    Methadone medical maintenance is the treatment of stable methadone-maintained patients in primary care physicians' offices under an exemption from federal methadone regulations. Reports from seven such programs in six states show high retention and low frequencies of illicit drug use. Patients and physicians indicate high levels of satisfaction. Although methadone maintenance has a long history of safety and efficacy, most methadone medical maintenance programs are no longer operating or accepting new patients. Federal regulations for standard methadone clinics allow some features of methadone medical maintenance, and advocacy for state approval of these changes is strongly recommended. PMID:26110221

    This paper discusses various difficulties which arise when the staff of a methadone maintenance clinic must come to grips with the manifest and latent issues in service delivery. A solution is suggested which involves severing the tie between methadone and the behaviors which are reinforced by its use. (Author)

    A comprehensive study of an urban methadone clinic with supervised urine analyses for illicit drugs was conducted over an 18 month period for a 133 patient cohort as they entered or remained in methadone maintenance for narcotic addiction. Overall retention during the study was 85%, with significantly (p < .05) higher daily methadone doses (mean 67.1 mg +/- 2.1) in those patients still in treatment at the end of the study. Predictably, illicit opioid use was dramatically reduced, to 10% as measured by urine toxicology in the last month of treatment. Moreover, significantly more patients stopped regular cocaine abuse (69%) than started using cocaine (10%, Fisher's exact test, p = .02). Thus, with effective methadone maintenance using adequate dosages, the majority of patients remain in treatment and reduce cocaine abuse as well as illicit opioid use, with implications for public health by reducing the spread of infectious diseases including hepatitis B, C, D and human immunodeficiency virus (HIV-1).

    Background: Clopidogrel is a prodrug that converts in the liver to an active thiol metabolite, which irreversibly inhibits the platelet P2Y12 adenosine diphosphate receptor. It seems that methadone as CYP2C19 inhibitor affects ticlopidine activity in vivo. This study aimed to test the ability of methadone in changing ticlopidine pharmacokinetics. Methods: We conducted a case–control study in 10 subjects. The cases (5 subjects) in our study were addicts who were receiving methadone maintenance treatment (MMT) for preventing opium withdrawal symptoms. The control group were opiate users before starting MMT. In both groups, the patients received clopidogrel (75mg/day) for 5 days. On the 6th day, the subjects returned to the clinic, blood samples were taken up to 12 hours following clopidogrel dosing in case and control groups. Plasma concentration of clopidogrel was measured by GC-MAS. Noncompartmental pharmacokinetic analysis was performed using Microsoft Excel software to estimate PK parameters. Results: In this study, methadone decreased clopidogrel clearance by 25% and increased the AUC0-inf nearly 1.3 fold during the coadministration of clopidogrel as an antiplatelet drug. Conclusion: A significant decrease in the clearance of clopidogrel during the coadministration of methadone consistent with a decrease in clopidogrel conversion to its active metabolite and this may decrease its efficacy and may have life-threatening consequences for the patients undergoing clopidogerel maintenance therapy.

    Opioid addiction influences many physiological functions including reactions of the immune system. The objective of this study was to investigate the immune system function in heroin addicted patients undergoing methadone maintenance treatment (MMT) compared to healthy controls. We tested the cytokine production of IL-1β, IL-6, IL-8, IL-10 and tumor necrosis factor (TNF)-α from a group of heroin addicts (n=34) and healthy controls (n=20). The results show that production of IL-1β, IL-6 and IL-8 was significantly higher in the group of methadone-maintained patients than in the healthy control group. Plasma TNF-α and IL-6 levels were significantly correlated with the dairy methadone dosage administered, and the IL-1β level was significantly correlated with the duration of methadone maintenance treatment. These findings suggest that methadone maintenance treatment influences the immune system functions of opioid-dependent patients and may also induce long-term systemic inflammation. PMID:25660662

    BACKGROUND. Interim methadone maintenance has been proposed as a method of providing clinically effective services to heroin addicts waiting for treatment in standard comprehensive methadone maintenance programs. METHODS. A clinic that provided initial medical evaluation, methadone medication, and AIDS education, but did not include formal drug abuse counseling or other social support services was established in New York City. A sample of 301 volunteer subjects recruited from the waiting list for treatment in the Beth Israel methadone program were randomly assigned to immediate entry into the interim clinic or a control group. RESULTS. There were no differences in initial levels of illicit drug use across the experimental and control groups. One-month urinalysis follow-up data showed a significant reduction in heroin use in the experimental group (from 63% positive at intake to 29% positive) with no change in the control group (62% to 60% positive). No significant change was observed in cocaine urinalyses (approximately 70% positive for both groups at intake and follow-up). A higher percentage of the experimental group were in treatment at 16-month follow-up (72% vs 56%). CONCLUSIONS. Limited services interim methadone maintenance can reduce heroin use among persons awaiting entry into comprehensive treatment and increase the percentage entering treatment. PMID:1659236

    Background Methadone maintenance has received little scientific attention regarding neurocognitive effects. This study is aimed to assess the neuropsychological performance of methadone maintenance patients (MMP) compared to those healthy controls. Methods Thirty-five MMP and 35 healthy controls, matched for age, gender, education and employment status, examined on a battery of tests aimed at assessing verbal fluency, executive functions, verbal memory, and working memory, using controlled oral word association test (COWAT), trial making test (TMT) Part A and B, Rey auditory verbal learning test (RAVLT), and backward digit span. Findings MMP performed significantly poorly than controls in cognitive domains of verbal fluency, executive function, and verbal memory. MMP did not exhibit impairment in working memory, and TMT Part A compared to controls. Conclusion These results suggest that methadone consumption induces significant cognitive impairment that could compromise drug-treatment outcomes in MMP. PMID:26885347

    2012-01-01

    Background Although methadone has been used for the maintenance treatment of opioid dependence for decades, it was not introduced in China or Taiwan until 2000s. Methadone-drug interactions (MDIs) have been shown to cause many adverse effects. However, such effects have not been scrutinized in the ethnic Chinese community. Methods The study was performed in two major hospitals in southern Taiwan. A total of 178 non-HIV patients aged ≥ 20 years who had participated in the Methadone Maintenance Treatment Program (MMTP) ≥ 1 month were recruited. An MDI is defined as concurrent use of drug(s) with methadone that may result in an increase or decrease of effectiveness and/or adverse effect of methadone. To determine the prevalence and clinical characteristics of MDIs, credible data sources, including the National Health Insurance (NHI) database, face-to-face interviews, medical records, and methadone computer databases, were linked for analysis. Socio-demographic and clinical factors associated with MDIs and co-medications were also examined. Results 128 (72%) MMTP patients took at least one medication. Clinically significant MDIs included withdrawal symptoms, which were found among MMTP patients co-administered with buprenorphine or tramadol; severe QTc prolongation effect, which might be associated with use of haloperidol or droperidol; and additive CNS and respiratory depression, which could result from use of methadone in combination with chlorpromazine or thioridazine. Past amphetamine use, co-infection with hepatitis C, and a longer retention in the MMTP were associated with increased odds of co-medication. Among patients with co-medication use, significant correlates of MDIs included the male gender and length of co-medication in the MMTP. Conclusions The results demonstrate clinical evidence of significant MDIs among MMTP patients. Clinicians should check the past medical history of MMTP clients carefully before prescribing medicines.

    This study evaluated the relationship between the plasma concentration of l-methadone and response to methadone in real-world patients, in order to identify a minimum plasma concentration above which methadone treatment is effective. Ninety-four patients with opioid dependence under maintenance methadone treatment were consecutively recruited. Response was defined as negative urine analyses in the three weeks prior to the blood sampling. The percentage of participants with a plasma l-methadone concentration between 100 and 250 ng/ml was 54.2% among those with a methadone dosage ≥60 mg/day. Plasma l-methadone concentrations were significantly higher in patients with negative urine analyses compared with those with positive urine analyses (median 93 vs. 77 ng/ml, Mann-Whitney test, P<0.05). Above plasma l-methadone concentrations of 200 ng/ml no heroin use was reported and urine analyses were negative. Moreover, above concentrations of 250 ng/ml craving was absent. Examination of demographic correlates of treatment outcome indicated that older age, a stable job and being married were protective against the use of heroin. Mean plasma l-methadone concentration was significantly lower in patients who used cannabis compared with those who did not use cannabis, after adjusting for methadone dosage. In conclusion our results identify specific cut-offs for plasma l-methadone concentrations about which therapeutic response is observed and provide new evidence that therapeutic response is associated with patient׳s demographic characteristics. This underscores the need to monitor plasma methadone concentrations as part of Drug Addiction Services routine practice, in order to provide an objective framework for changing the methadone dosage.

    Methadone maintenance treatment (MMT) has long been used to treat heroin-dependent patients. However, satisfaction with methadone in this patient population is unknown. The aim of this cross-sectional case-control study was to evaluate satisfaction with methadone in heroin-dependent patients with current substance use disorders (SUDs). Cases included 152 methadone-maintained patients with current SUD, requiring inpatient detoxification treatment, and controls included 33 methadone-maintained patients in sustained full remission for SUD. Satisfaction with methadone as a medication to treat heroin addiction was measured by using the Scale to Assess Satisfaction with Medications for Addiction Treatment-methadone for heroin addiction (SASMAT-METHER). The SASMAT-METHER subscales assess the following domains: personal functioning and well-being, antiaddictive effect on heroin, and antiaddictive effect on other substances. Compared with patients with remitted SUD, patients with current SUD scored lower on all SASMAT-METHER assessments. In such patients, overall SASMAT-METHER scores were independently and negatively associated with downward desired adjustment of methadone dose and days of heroin use during last month; although various sets of factors were independently associated with each of the SASMAT-METHER subscales, the only determinant of dissatisfaction on all subscales was the desire for downward adjustment of methadone dose. In summary, MMT patients with current SUD are less satisfied with methadone than MMT patients with remitted SUD. In patients with current SUD, downward desired adjustment of methadone dose and days of heroin use during last month are independently associated with overall dissatisfaction with methadone.

    Incarcerated intravenous heroin users have more problematic patterns of heroin use, but are less likely to access methadone maintenance treatment by their own initiative than heroin users in the community. The present study examined predictors for receiving methadone maintenance treatment post-release among incarcerated intravenous heroin users within a 24-month period. This cohort study recruited 315 incarcerated intravenous heroin users detained in 4 prisons in southern Taiwan and followed up within the 24-month period post-release. Cox proportional hazards regression analysis was applied to determine the predictive effects of sociodemographic and drug-use characteristics, attitude toward methadone maintenance treatment, human immunodeficiency virus serostatus, perceived family support, and depression for access to methadone maintenance treatment after release. There were 295 (93.7%) incarcerated intravenous heroin users released that entered the follow-up phase of the study. During the 24-month follow-up period, 50.8% of them received methadone maintenance treatment. After controlling for the effects of the detainment period before and after recruitment by Cox proportional hazards regression analysis, incarcerated intravenous heroin users who had positive human immunodeficiency virus serostatus (HR = 2.85, 95% CI = 1.80-4.52, p < .001) and had ever received methadone maintenance treatment before committal (HR = 1.94, 95% CI = 1.23-3.05, p < .01) were more likely to enter methadone maintenance treatment within the 24-month follow-up period. Positive human immunodeficiency virus serostatus with fully subsidized treatment and previous methadone maintenance treatment experiences predicted access of methadone maintenance treatment post-release. Strategies for getting familiar with methadone maintenance treatment during detainment, including providing methadone maintenance treatment prior to release and lowering the economic burden of receiving treatment, may

    Abstract Problem In Malaysia, human immunodeficiency virus (HIV) infection is highly concentrated among people who inject opioids. For this reason, the country undertook a three-phase roll-out of a methadone maintenance treatment (MMT) programme. In Phase 3, described in this paper, MMT was implemented within prisons and retention in care was assessed. Approach After developing standard operating procedures and agreement between its Prisons Department and Ministry of Health, Malaysia established pilot MMT programmes in two prisons in the states of Kelantan (2008) and Selangor (2009) – those with the highest proportions of HIV-infected prisoners. Community-based MMT programmes were also established in Malaysia to integrate treatment activities after prisoners’ release. Local setting Having failed to reduce the incidence of HIV infection, in 2005 Malaysia embarked on a harm reduction strategy. Relevant changes Standard operating procedures were modified to: (i) escalate the dose of methadone more slowly; (ii) provide ongoing education and training for medical and correctional staff and inmates; (iii) increase the duration of methadone treatment before releasing prisoners; (iv) reinforce linkages with community MMT programmes after prisoners’ release; (v) screen for and treat tuberculosis; (vi) escalate the dose of methadone during treatment for HIV infection and tuberculosis; and (vii) optimize the daily oral dose of methadone (> 80 mg) before releasing prisoners. Lessons learnt Prison-based MMT programmes can be effectively implemented but require adequate dosing and measures are needed to improve communication between prison and police authorities, prevent police harassment of MMT clients after their release, and improve systems for tracking release dates.

    The use and effectiveness of contingency contracting and systematic desensitization with heroin addicts being treated in methadone maintenance programs are discussed. Both behavior therapies can be practically implemented in methadone maintenance programs to supplement methadone pharmacotherapy. Contingency contracting has been effectively employed to reduce illicit drug use and to manage patients in the clinic. Systematic desensitization has less effect on actual heroin usage yet effectively reduces the fear of withdrawal and general anxiety, while improving self-image, assertiveness, and adjustment in the community. A clinic protocol that incorporates all three therapies-methadone maintenance, contingency contracting, and systematic desensitization-is proposed. PMID:11061683

    To improve the electrocardiogram screening process and early detection of patients at high risk for cardiac arrhythmias, the authors created a model in their clinic where they provided an onsite electrocardiogram screening that might be feasible and practical. The authors then performed a retrospective chart review to access the efficacy and feasibility of their new onsite procedure in identifying methadone maintained patients at high risk for cardiac arrhythmias. Records from all patients who are currently or had previously been maintained on methadone in the methadone maintenance program at the Atlanta VA Medical Center between 2002 and 2009 were evaluated. Of the 140 patients treated at the clinic between 2002 and 2009, 85 were excluded from the study because they had been treated as guests (had been in treatment in other clinics but received methadone dosing temporarily from our clinic), were treated in the clinic for less than 6 months, or dropped out of treatment. Thus, 55 patient charts were selected for review. Most patients (95%) received baseline and annual electrocardiogram screening. The average baseline QTc was (417 +/- 30) and most recent QTc (442 +/- 25). This QTc prolongation from baseline showed statistical significance (P < .0001). Sixty-seven percent of patients had statistically significant QTc prolongation from baseline but was less than 450 ms (mean: 428 +/- 16, P = .008). Twenty-seven percent of patients had statistically significant QTc prolongation from baseline of more 450 ms but was less than 500 ms (mean: 460 +/- 8, P < .0001). Six percent of patients had statistically significant QTc prolongation from baseline of more 500 ms (mean: 503 +/- 1.15, P = .027). Recent cocaine use was the only individual variable that showed statistically significant correlation with QTc prolongation (F = 6.98, P = .01).

    Methadone medical maintenance (MMM) reduces the reporting schedule for stable and well-functioning methadone maintenance patients to once a month, with counseling provided by medical staff. We report on the 12-month outcomes of 92 highly stable methadone maintenance patients randomly assigned to one of three study conditions: routine care, MMM at the methadone maintenance program, and MMM at a physician's office. Methadone medical maintenance patients received a 28-day supply of methadone, whereas routine care patients received five or six take-home methadone doses each week. All patients performed a medication recall once a month and submitted two urine samples each month. An adaptive stepped-care system of treatment intensification was used for patients who failed recall or who had drug-positive urine specimens. Seventy-seven patients completed the 12-month study period. Dropout was caused primarily by problems with handling methadone and disliking the recall frequency. There were low rates of drug use or failed medication recall. Treatment satisfaction was high in all groups, but the MMM patients initiated more new employment or family/social activities than did routine care patients over the study period. The stepped-care approach was well tolerated and matched patients to an appropriate step of service within a continuum of treatment intensity. PMID:17084792

    The authors examine methadone plasma levels in 31 depressed methadone-maintained opiate addicts enrolled in a 12-week placebo-controlled, double-blind study of sertraline. Between baseline and week 6, patients on sertraline showed a mean increase in methadone plasma level/dose (P/D) ratio of 26% (SD = 43%, range -32% to +118%), while patients on placebo showed a mean decrease of 16% (SD = 27%, range -62% to +50%). This difference was significant (p < 0.02). The sertraline and placebo groups did not differ in reported side effects or methadone dose adjustments. Between weeks 6 and 12, methadone P/D in the sertraline group decreased back towards baseline, and the treatment groups did not differ significantly at week 12. The results suggest sertraline may produce a modest increase in methadone serum levels over the first six weeks of treatment. Depression and anxiety disorders are common in methadone-maintained patients. Serotonin uptake inhibitors are attractive choices for treatment due to their low toxicity and low abuse potential, but these agents variously inhibit isoenzymes responsible for the metabolism of methadone. Clinicians treating depressed or anxious methadone patients with second-generation antidepressants should monitor for clinical signs of increased or decreased methadone levels and consider monitoring serum methadone levels.

Controlling for age, a stepwise discriminant analysis employing a backward elimination model was performed with the SCL-90-R's nine symptom factors to determine if the addicts described different levels of symptomatology. Interpersonal sensitivity and depression differentiated between the two groups; the ambulatory detoxification patients were more depressed and described less interpersonal sensitivity than the methadone maintenance patients. The results supported the contention that heroin addicts seeking ambulatory detoxification or methadone maintenance may display different symptoms. PMID:7128452

    Methadone maintenance therapy has been found to be an effective harm reduction treatment for opioid use disorder. However evidence of its benefits over a longer duration of treatment is limited as most studies focus on its short term benefits. As methadone maintenance therapy reaches a decade since its implementation in Malaysia, this study sought to examine the effectiveness of methadone treatment, change in quality of life among patients since entry to methadone treatment, as well as factors predicting the magnitude of change in quality of life. This study found that methadone maintenance therapy was effective in reducing heroin use, injecting practices and crime, and in improving in social functioning and physical symptoms, but not in reducing sex-related HIV risk-taking behavior. Though patients had a significantly better quality of life at follow-up than at entry to methadone maintenance therapy, the improvement in quality of life was not significantly greater as the duration of treatment increased. Age above 50 years old, human immunodeficiency virus (HIV) positive status and physical symptoms predicted a poorer improvement in quality of life between baseline and follow-up. On the other hand, patients with hepatitis B showed a greater improvement in quality of life in the social relationships domain compared to patients without hepatitis B. In conclusion, methadone maintenance therapy is an effective treatment for opioid use disorder and improves quality of life but its benefits in further improving quality of life beyond a decade of treatment need further evaluation.

  10. "Living with the dirty secret": problems of disclosure for methadone maintenance clients.

    1992-01-01

    This article focuses on the management of stigma by methadone maintenance patients. It explores (1) the consequences of this persistent stigma, which necessitates the need for secrecy, (2) the adaptations made in order to successfully "pass as normal," and (3) the contexts in which methadone-maintained individuals decide to disclose their stigmatized status. The data reported and analyzed were gathered between 1980 and 1989 during a series of studies funded by the National Institute on Drug Abuse. The three studies--"Women on Methadone," "Getting Off Methadone," and "Alameda County Methadone Study"--utilized qualitative, in-depth interviews and ethnographic sampling techniques, primarily chain referral sampling. After ten years of interviewing women and men in various stages of their methadone maintenance careers, recurring themes emerged, one of which was that being a methadone patient is a marginal identity; not quite junkie, not quite conventional. Clients' efforts to manage this stigmatized identity were often shrouded in anguish and secrecy. Methadone patients were in a kind of identity limbo; a holding pattern between two extremely different social worlds. They were trying to effect an identity transformation; however, in many circumstances they were still associated with and defined by their "dirty secret." PMID:1432404

    We sought to determine the prevalence, patterns, and correlates of past-month illicit methadone use and history of regular illicit use among stimulant-using methadone maintenance treatment patients. We obtained self-reported information on illicit methadone use from 383 participants recruited from six community-based methadone maintenance programs. Overall, 1.6% of participants reported illicit use in the past month, and 4.7% reported a history of regular use. Younger age and history of outpatient psychological treatment were associated with increased odds of past-month illicit use. Illicit methadone use among patients in maintenance programs is infrequent; however, a number of factors may increase risk of illicit use. PMID:18612886

    Methadone maintenance treatment (MMT) can induce impairments in brain function and structure, despite its clinical effectiveness. However, the effect of chronic MMT on brain white matter (WM) is not fully known. Thirty-three MMT patients underwent diffusion tensor imaging (DTI) twice – at the start of the study (Scan1) and one year later (Scan2). Tract-based spatial statistics were used to investigate changes in fractional anisotropy (FA), axial diffusivity (AD) and radial diffusivity (RD) between the two scans. The correlations between DTI indices and methadone consumption and neuropsychological status were analysed. We found significantly decreased FA, decreased AD and increased RD in Scan2 in extensive WM regions; overlapping regions were found in the left posterior limb and the retrolenticular part of internal capsule, superior and posterior corona radiata, bilateral external capsule and the right superior longitudinal fasciculus. In addition, the change of FA in the overlapping regions was positively correlated with the accumulated dosage of methadone use, the RD value in Scan2 and non-planning impulsiveness (NPI) measured at follow-up. The results suggest that methadone has damaging effects on WM integrity. The dose-dependent pattern and characteristics of the impairment may suggest new strategies for MMT. PMID:26794650

    Buprenorphine may be used to treat opioid dependence in office-based settings, but treatment models are needed to ensure access to psychosocial services needed by many patients. We describe a novel buprenorphine treatment program colocated with methadone maintenance and outpatient chemical dependency services. We conducted a retrospective chart review of the first 40 consecutive patients initiating buprenorphine treatment in this program to determine characteristics associated with treatment retention. Exclusion criteria were current alcohol or benzodiazepine dependence. Secondary drug users and patients who were psychiatrically or medically ill were included. At 6 months, 60% (n = 24) were retained, 13% (n = 5) tested positive for opiates, and 25% (n = 10) tested positive for secondary substances. Patients who were older (odds ratio [OR] per year of age = 1.1, confidence interval [CI] = 1.0-1.2) and those who were employed (OR = 9.8, CI = 1.8-53.1) were more likely to remain in treatment, but other variables were not associated with retention. Our experience demonstrates that buprenorphine can be successfully integrated into outpatient substance abuse treatment. PMID:17588493

    Analyses examined whether addicts reporting themselves coerced into drug abuse treatment by actions of the criminal justice system differed from voluntary admissions in their response to treatment, and whether such responsiveness varied across gender or ethnicity. Six hundred eighteen methadone maintenance clients admitted to programs in six southern California counties were categorized into high, moderate, and low legal coercion levels. Multivariate analysis of variance procedures for repeated measures (before, during, and after initial treatment episode) were used to test relevant hypotheses. Dependent variables included criminal justice system contact, criminal activities, drug and alcohol involvement, and measures of social functioning. Few differences within any measured domain were found among the three groups. All groups were similar in showing substantial improvement in levels of narcotics use, criminal activities, and most other behaviors during treatment with some regression in these behaviors posttreatment. Results support legal coercion as a valid motivation for treatment entry; those coerced into treatment respond in ways similar to voluntary admissions regardless of gender or ethnicity. PMID:8438834

    Three consecutive, professionally led (as opposed to self-help) groups following the 12-step program (TSP) were integrated into a methadone maintenance treatment (MMT) program that included 32 heroin-addicted individuals in recovery. This report describes our experience in meeting the challenges that arose and our conclusions regarding the therapeutic potential of this integration. A professional therapeutic staff guided the groups. In-depth interviews of 10 participants and the reflections of the group leaders provided data for learning about the groups' experience. Initially the participants rejected the concepts of Step 1, powerlessness and unmanageability of life. The assimilation of Step 4 (defining character defect) also aroused some resistance. The participants eventually adopted the pragmatic aspects of TSP, including its terminology. The establishment of a common language of recovery helped to create group coherence and a sense of belonging, and helped to meet the needs of those who felt stigmatized by both the nonaddicted and addicted population undergoing nonmethadone recovery. TSP could be adapted to various aspects of daily life, produced a sense of self-efficacy, and stimulated motivation for change. Therapeutic implications are discussed. PMID:20921264

    There are about 28,500 people who inject drugs (PWID) in Nepal and HIV prevalence among this group is high. Nepal introduced harm reduction services for PWID much earlier than other countries in South Asia. Methadone maintenance treatment (MMT) was first introduced in Nepal in 1994. This initial small scale MMT programme was closed in 2002 but reopened in 2007 as an emergency HIV prevention response. It has since been scaled up to include three MMT clinics and continuation of MMT is supported by the Ministry of Home Affairs (MOHA; the nodal ministry for drug supply reduction activities) and has been endorsed in the recent National Narcotics policy. Pressure from drug user groups has also helped its reintroduction. Interestingly, these developments have taken place during a period of political instability in Nepal, with the help of strong advocacy from multiple stakeholders. The MMT programme has also had to face resistance from those who were running drug treatment centres. Despite overcoming such troubles, the MMT programme faces a number of challenges. Coverage of MMT is low and high-risk injecting and sexual behaviour among PWID continues. The finance for MMT is largely from external donors and these donations have become scarce with the current global economic problems. With a multitude of developmental challenges for Nepal, the position of MMT in the national priority list is uncertain. Ownership of the programme by government, a cost-effective national MMT scale up plan and rigorous monitoring of its implementation is needed. PMID:23845916

  17. Better retention of Malaysian opiate dependents treated with high dose methadone in methadone maintenance therapy

    2010-01-01

    Background Methadone is a synthetic opiate mu receptor agonist that is widely used to substitute for illicit opiates in the management of opiate dependence. It helps prevent opiate users from injecting and sharing needles which are vehicles for the spread of HIV and other blood borne viruses. This study has the objective of determining the utility of daily methadone dose to predict retention rates and re-injecting behaviour among opiate dependents. Methods Subjects comprised opiate dependent individuals who met study criteria. They took methadone based on the Malaysian guidelines and were monitored according to the study protocols. At six months, data was collected for analyses. The sensitivity and specificity daily methadone doses to predict retention rates and re-injecting behaviour were evaluated. Results Sixty-four patients volunteered to participate but only 35 (54.69%) remained active and 29 (45.31%) were inactive at 6 months of treatment. Higher doses were significantly correlated with retention rate (p < 0.0001) and re-injecting behaviour (p < 0.001). Of those retained, 80.0% were on 80 mg or more methadone per day doses with 20.0% on receiving 40 mg -79 mg. Conclusions We concluded that a daily dose of at least 40 mg was required to retain patients in treatment and to prevent re-injecting behaviour. A dose of at least 80 mg per day was associated with best results. PMID:21167035

    This study intended to (1) describe the baseline patient satisfaction level and preferred coping strategies and (2) assess patient satisfaction and coping mechanisms pre- and postintervention. Patients on methadone maintenance treatment (MMT) in Terengganu, Malaysia, were randomized into either MMT or MMT plus auricular acupuncture (MMT + AA) groups. All received the standard MMT, while participants on MMT + AA underwent concurrent AA session thrice weekly for 2 months (each session = 30 minutes). Data analysis was carried out using SPSS 16.0, employing descriptive and nonparametric statistics. Participations were received from 97 eligible male patients (median age = 36.0 years; Malay = 97.9%). After screening for dropouts, only 69 patients were considered for subsequent analysis (MMT = 40; MMT + AA = 29). At preintervention, both groups did not differ significantly in the parameters investigated. During postintervention, no significant difference was detected for satisfaction level but coping-wise, substance use was significantly and frequently adopted by MMT + AA patients compared to MMT respondents (P < .05). On separate analysis, those who received MMT alone adopted active coping, venting, and self-blame significantly more frequently postintervention (P < .05). Nevertheless, no significant difference for coping styles of MMT + AA patients was exhibited over time (P >.05). The addition of AA therapy into the standard MMT treatment did not seem to influence patient satisfaction and their coping ways. PMID:23764566

    Background: Measurement of life quality as an index of health status has a widespread application in health care domain. Objectives: The current study aimed to determine the quality of life of referents to addiction cessation centers of Iran. Patients and Methods: In this cross-sectional study, 988 addicts who had referred to addiction cessation centers in Shahroud were studied through SF-36 questionnaire. The data were analyzed using linear regression in structural equation modeling and STATA 12 statistical software. Results: The mean ± SD age of the participants was 41.2 ± 11.8 years. Most of the referents used smoking followed by eating method of opium abuse. The mean ± SD score of life quality was 67.8 ± 17.2, the mean ± SD score of life quality in physical health dimension was 76.9 ± 26.7, and the mean ± SD score in mental health dimension was 64.5 ± 18.4. Univariate analysis showed a significant relationship between life quality and gender, place of residence, education, occupation, marital status, and income (P ≤ 0.05). However, in multivariate analysis a significant relationship was observed only between gender, socioeconomic status, and quality of life score. Conclusions: Although most studies have reported low and weak quality of life in addicts, the findings of this study shows that the life quality score of addicts is rather good. It seems that the maintenance treatment that addicts receive in addiction cessation centers has been effective in improving the quality of life of the patients. Hence, expanding methadone treatment centers can play a leading role in the improvement of life quality in addicts. PMID:26870708

    This study examined the relationship of pathological gambling to negative treatment outcomes for methadone maintenance patients aged 50 or older. The study included 130 methadone maintenance patients. Pathological gambling was determined using the Lie-Bet, a screen for pathological gambling; the outcomes were remaining in treatment and negative urine screens for drug use. Twenty percent of the sample identified as pathological gamblers. Pathological gambling was unrelated to remaining in treatment or negative urine screens. Although pathological gambling had no adverse influence on these treatment outcomes, the prevalence of pathological gambling suggests that screening for it may provide insights about other concerns.

    The World Health Organization classifies methadone as an essential medicine, yet methadone maintenance therapy remains widely unavailable in criminal justice settings throughout the United States. Methadone maintenance therapy is often terminated at the time of incarceration, with inmates forced to withdraw from this evidence-based therapy. We assessed whether these forced withdrawal policies deter opioid-dependent individuals in the community from engaging methadone maintenance therapy in two states that routinely force inmates to withdraw from methadone (N = 205). Nearly half of all participants reported that concern regarding forced methadone withdrawal during incarceration deterred them engaging methadone maintenance therapy in the community. Participants in the state where more severe methadone withdrawal procedures are used during incarceration were more likely to report concern regarding forced withdrawal as a treatment deterrent. Methadone withdrawal policies in the criminal justice system may be a broader treatment deterrent for opioid-dependent individuals than previously realized. Redressing this treatment barrier is both a health and human rights imperative. PMID:23433809

    Objective Promethazine has been reported to be misused in conjunction with opioids in several settings. Promethazine misuse by itself or in conjunction with opioids may have serious adverse health effects. To date, no prevalence data for the nonmedical use of promethazine has been reported. This study examines the prevalence and correlates of promethazine use in two different populations in San Francisco, California, USA: methadone maintenance clinic patients and community-based injection drug users (IDUs). Methods We analyzed urine samples for the presence of promethazine and reviewed the clinical records for 334 methadone maintenance patients at the county methadone clinic. Separately, we used targeted sampling methods to recruit and survey 139 community-based opioid IDUs about their use of promethazine. We assessed prevalence and factors associated with promethazine use with bivariate and multivariate statistics. Results The prevalence of promethazine positive urine samples among the methadone maintenance patients was 26 percent. Only 15 percent of promethazine positive patients had an active prescription for promethazine. Among IDUs reporting injection of opiates in the community-based survey, 17 percent reported having used promethazine in the past month; 24 percent of the IDUs who reported being enrolled in methadone treatment reported using promethazine in the past month. Conclusions The finding that one quarter of methadone maintenance patients in a clinic or recruited in community settings have recently used promethazine provides compelling evidence of significant nonmedical use of promethazine in this patient population. Further research is needed to establish the extent and nature of nonmedical use of promethazine. PMID:23385449

    The efficacy of methadone maintenance in opioid addiction was assessed in terms of programme retention rate and reduction of illicit opioid use by means of a meta-analysis of randomised, controlled and double blind clinical trials. The results were compared with interventions using buprenorphine and levo-acetylmethadol (LAAM). Trials were identified from the PubMed database from 1966 to December 1999 using the major medical subject headings 'methadone' and 'randomised controlled trial'. Data for a total of 1944 opioid-dependent patients from 13 studies were analysed. Sixty-four percent of patients received methadone, administered either as fixed or adjusted doses. Thus, 890 patients received > or = 50 mg/day (high dose group) and 392 were given < 50 mg/day (low dose group). Of 662 controls, 131 received placebo, 350 buprenorphine (265 at doses > or = 8 mg/day and 85 at doses < 8 mg/day) and 181 LAAM. High doses of methadone were more effective than low doses in the reduction of illicit opioid use (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.26--2.36). High doses of methadone were significantly more effective than low doses of buprenorphine (< 8 mg/day) for retention rates and illicit opioid use, but similar to high doses of buprenorphine (> or = 8 mg/day) for both parameters. Patients treated with LAAM had more risk of failure of retention than those receiving high doses of methadone (OR 1.92, 95% CI 1.32--2.78). It is proposed that in agonist-maintenance programmes, oral methadone at doses of 50 mg/day or higher is the drug of choice for opioid dependence. PMID:11841899

    A variety of studies evidenced a relationship between drug use disorders and sexual dysfunction. In particular, heroin and opioid agonist medications to treat heroin dependence have been found to be associated with erectile dysfunction and reduced libido. Controversial findings also indicate the possibility of factors other than the pharmacological effects of opioid drugs concurring to sexual dysfunction. With the present study, we investigated the link between sexual dysfunction and long-term exposure to opioid receptor stimulation (heroin dependence, methadone maintenance treatment, methadone dosage), the potentially related hormonal changes reflecting hypothalamus-pituitary-gonadal axis function and prolactin (PRL) pituitary release, the role of adverse childhood experiences in the clinical history and the concomitant symptoms of comorbid mental health disorders in contributing to sexual problems. Forty male patients participating in a long-term methadone treatment program were included in the present study and compared with 40 healthy control subjects who never used drugs nor abused alcohol. All patients and controls were submitted to the Arizona Sexual Experiences Scale (ASEX), Child Experiences of Care and Abuse-Questionnaire (CECA-Q) and the Symptom Check List-90 Scale. A blood sample for testosterone and PRL assays was collected. Methadone dosages were recorded among heroin-dependent patients on maintenance treatment. Methadone patients scored significantly higher than controls on the 5-item rating ASEX scale, on CECA-Q and on Symptoms Check List 90 (SCL 90) scale. Testosterone plasma levels were significantly lower and PRL levels significantly higher in methadone patients with respect to the healthy control group. ASEX scores reflecting sexual dysfunction were directly and significantly correlated with CECA-Q neglect scores and SCL 90 psychiatric symptoms total score. The linear regression model, when applied only to addicted patients, showed that

    Background With up to 40% of opioid injectors infected with HIV, Ukraine has one of the most concentrated HIV epidemics in the world, mainly due to unsterile injection practices and a historical absence of effective prevention services. Harm reduction programs, including syringe exchange and a small buprenorphine treatment program, were introduced in 2004 and methadone maintenance was allowed in 2007. Despite an initial expansion, by 2009, only 3221 injectors were receiving methadone treatment. A growing body of research on methadone maintenance has found high retention rates with reduction in opioid use and HIV risk behaviors. We report on the acceptability and initial outcome of methadone treatment as a function of HIV status, an issue that has not yet been reported for injectors in Ukraine. Methods Longitudinal observational study of a 12-week course of methadone treatment in 25 HIV+ and 25 HIV− opioid addicted individuals recruited from a harm reduction program and the city AIDS Center. Drug use and HIV risk were assessed at baseline and weeks 4, 8, 12 and 20; all patients were offered continued methadone maintenance in the Kyiv city program at the end of 12 weeks. Results Fifty-four individuals were asked if they were interested in the study and 50, demographically similar to other samples of opioid addicted Ukrainians, agreed to participate. Two died of non-study related causes; the other 48 completed assessments at weeks 4, 8 and 12, and 47 completed followups at week 20. Significant reductions were seen in use of heroin (p<. 0001), other opiates/analgesics (p< 0.0001), and HIV risk behaviors (drug, sex, total; all p <0.0001). All 48 patients chose to continue methadone after the 12-weeks of study medication ended. Unlike most opioid treatment studies, sexual risk was somewhat higher than injecting risk at study intake. Conclusions Methadone maintenance was well accepted by HIV+ and HIV− opioid dependent individuals and has the potential for significant

    Devising interventions to provide integrated treatment for addiction and medical problems is an urgent issue. This study piloted a structural intervention, Directly Administered Antiretroviral Therapy (DAART), to assist methadone-maintenance patients in HIV medication adherence. Twenty-four participants received: (1) antiretroviral medications at the methadone clinic daily before receiving their methadone; (2) take-home antiretroviral medication for days they were not scheduled to attend the methadone clinic, and (3) brief adherence counseling to address adherence barriers. DAART lasted 24 weeks, with a planned step-down to twice-weekly administration in weeks 25-36, followed by self-administration in weeks 37-48. Retention rates at weeks 24, 36, and 48 were 83, 92, and 75% respectively. DAART was associated with improvement in the proportion of participants achieving viral suppression as well as with high medication adherence rates (clinic-verified; 85% and self-reported 97%) during the active intervention phase. DAART was effective as an intervention but did not promote transition to self-administration. This study demonstrates that DAART is adaptable and simple enough to be implemented into methadone treatment programs interested in providing HIV adherence services. PMID:23007110

    Opiate addiction influences many physiological functions including immune responses. The objective of this study was to investigate the immune system function in heroin addicted patients submitted to methadone or buprenorphine maintenance treatment compared to untreated heroin addicts and healthy controls. Four groups were studied: group A included nine heroin addicted subjects, who were still injecting heroin; groups B and C were composed of 12 patients previously addicted to heroin, being treated with methadone (mean dosage 58+/-12.7 mg/day) or buprenorphine (mean dose 9.3+/-2.3mg/day) since at least 6 months; group D was composed of 15 sex and age matched healthy controls. Lymphoproliferation and peripheral mononuclear cell cultures production of the Th1 cytokines IL-2 and IFN-gamma, the Th2 cytokine IL-4, and of the pro-inflammatory cytokine TNF-alpha were evaluated in all the patients and controls. PHA-lymphoproliferation was lower in untreated heroin addicts than in controls, while it was normal in methadone and buprenorphine treated patients. An altered Th1/Th2 balance, characterized by reduced IL-4, IFN-gamma and TNF-alpha but normal IL-2 levels, was present in untreated heroin addicted subjects, while the Th1/Th2 balance was well conserved in the methadone and buprenorphine groups. These findings suggest that the immune system abnormalities in heroin addicted patients can be restored to almost normal values by controlled treatment with methadone and buprenorphine.

    The escalating problem of opiate dependence in Malaysia and the limitations of regimental approach of forced admission to rehabilitation centres had triggered the government to expand the methadone maintenance therapy to become a national programme. This study aimed to evaluate the short-term outcomes of the Methadone Maintenance Therapy programme in one of the busiest hospital in east coast Malaysia. We also explored the prevalence on non-compliance and factors associated to it. A total of 172 patient case notes at Methadone Clinic Hospital Tengku Ampuan Afzan (HTAA) were retrieved for relevant data. A short survey was also conducted to determine the subjects' current employment and marital status. The programme's retention rate was 62% and factors associated with poor compliance were unemployment, low quality of life scores and low dose of methadone. A special attention on the patients with these three risk factors may improve their compliance to MMT. The short-term evaluation of MMT at HTAA revealed favourable findings. PMID:23770945

    This study examined outcome variables for 160 opiate injection drug users (IDUs) who entered methadone maintenance between baseline and 6 month follow-up. Outcome variables of interest included drug use, productivity and HIV risk behaviors. Participants were recruited through street outreach in Denver, Colorado from 2000 through 2004 using targeted sampling. The sample was primarily male, 48% White, averaged 39 years of age and had been injecting drugs for an average of nearly 20 years. Significant improvements were found in univariate tests. Logistic regression revealed that spending more time in treatment was a significant predictor of positive outcomes on drug use and HIV risk behaviors. The results underscore the importance of retaining IDUs in methadone maintenance in order to maximize their treatment success. Results from this study show that time in treatment can affect many aspects of the participant’s life in a positive way, including reduction of HIV risk. PMID:19150202

    With some 30,000 dependent persons, opiate addiction constitutes a major public health problem in Switzerland. The Swiss Federal Office of Public Health (FOPH) has long played a leading role in the prevention and treatment of opiate addiction and in research on effective means of containing the epidemic of opiate addiction and its consequences. Major milestones on that path have been the successive "Methadone reports" published by that Office and providing guidance on the care of opiate addiction with substitution treatment. In view of updating the recommendations for the appropriateness of substitution treatment for opiate addiction, in particular for the prescription of methadone, the FOPH commissioned a multi-component project involving the following elements.

    Introduction Methadone has long been regarded as an effective treatment for opioid dependence. However, many patients discontinue maintenance therapy because of its side effects, with one of the most common being sexual dysfunction. Buprenorphine is a proven alternative to methadone. This study aimed to investigate sexual dysfunction in opioid-dependent men on buprenorphine maintenance treatment (BMT) and methadone maintenance treatment (MMT). The secondary aim was to investigate the correlation between sexual dysfunction and the quality of life in these patients. Methods Two hundred thirty-eight men participated in this cross-sectional study. Four questionnaires were used, the Mini International Neuropsychiatric Interview, Opiate Treatment Index, Malay version of the International Index of Erectile Function 15 (Mal-IIEF-15), and World Health Organization Quality of Life-BREF Scale. Multivariate analysis of covariance was used to examine the relationship between MMT and BMT and the Mal-IIEF 15 scores while controlling for all the possible confounders. Results The study population consisted of 171 patients (71.8%) on MMT and 67 (28.2%) on BMT. Patients in the MMT group who had a sexual partner scored significantly lower in the sexual desire domain (p < 0.012) and overall satisfaction (p = 0.043) domain compared with their counterparts in the BMT group. Similarly, patients in the MMT group without a sexual partner scored significantly lower in the orgasmic function domain (p = 0.008) compared with those in the BMT group without a partner. Intercourse satisfaction (p = 0.026) and overall satisfaction (p = 0.039) were significantly associated with the social relationships domain after adjusting for significantly correlated sociodemographic variables. Conclusions Sexual functioning is critical for improving the quality of life in patients in an opioid rehabilitation program. Our study showed that buprenorphine causes less sexual dysfunction than methadone. Thus

    Cocaine use is a significant problem among methadone maintenance clients. Contingency management (CM) is a reinforcement-based approach with demonstrated efficacy for reducing cocaine use. This study examines whether the efficacy of CM treatment for cocaine-dependent individuals receiving methadone maintenance for opioid dependence differs by ethnicity. Participants were 191 African American, Hispanic and White cocaine-dependent methadone maintenance clients, randomly assigned to standard methadone treatment or standard methadone treatment plus CM for 12 weeks. Hispanic participants were younger, less educated, and reported fewer years of cocaine use than African American and White participants and reported fewer years of heroin use than African American participants. African American participants were less likely to report a history of psychiatric symptoms or treatment compared to Hispanic and White participants. While CM was associated with longer duration of continuous cocaine abstinence and a greater proportion of submitted urine samples negative for cocaine, ethnicity was not related to treatment outcomes, and there was no significant interaction between treatment and ethnicity. CM appears to be an efficacious treatment for cocaine dependence among methadone maintenance clients, regardless of ethnicity. PMID:19290703

    Baseline drug use detected in urine toxicology has been shown to predict drug abuse treatment outcome, including response to contingency management interventions with drug abstinence as their target. This study examined the association between baseline urine test result and treatment outcome in stabilized methadone maintenance patients with ongoing stimulant use to determine whether abstinence incentives were differentially effective in those testing stimulant negative versus positive at study entry. Participants were 386 methadone-maintained patients who took part in a National Drug Abuse Treatment Clinical Trials Network multisite study aimed at reducing stimulant abuse during treatment (J. M. Peirce et al., 2006). At study intake, 24% of participants tested stimulant negative and 76% tested positive. Those testing negative at entry submitted 82% negative urines during the study versus 36% for those testing positive at entry (odds ratio [OR] = 8.67; confidence interval [CI] = 5.81-12.94). Compared with those receiving usual care, the addition of abstinence incentives resulted in a significant increase in stimulant-negative urine samples submitted during the study both for those testing negative at study entry (OR = 2.27; CI = 1.13- 4.75) and for those testing positive (OR = 1.84; CI = 1.25-2.71). These findings suggest that abstinence incentives have significant clinical benefits independent of initial drug use severity among methadone maintenance patients with ongoing stimulant drug use.

    Objectives Effective and safe pain management interventions in methadone maintenance treatment are needed. Methods We examined the feasibility (i.e., single session attendance) and acceptability (i.e., patient satisfaction, booster session attendance) of cognitive-behavioral therapy-informed groups for pain management: Coping with Pain, Relaxation Training, Group Singing, and Mindful Walking. Pre- and post-session measures were collected. Results 349 (out of a census of approximately 800) methadone-maintained patients attended at least one of the groups. Group satisfaction was high. Booster session attendance was numerically lower in Mindful Walking (15%) as compared to the other groups (at least 40%). Repeat attendance at Coping with Pain was associated with reduced characteristic pain intensity and depression, while repeat attendance at Relaxation Training was associated with decreased anxiety. Conclusions Coping with Pain, Relaxation Training, and Group Singing are transportable, affordable, adaptable, and tolerated well by patients with pain and show promise as components of a multimodal pain management approach in methadone maintenance treatment.

    Background: Methadone maintenance has remained the main modality of treatment for opioid dependent subjects. Side effects of methadone treatment may be potential obstacles to its continuation. Sleep quality and sexual function are two culture-based concerns, directly related to patients’ compliance with methadone maintenance treatment (MMT) program. Objectives: This research was conducted to examine the frequency of sleep disparity and sexual dysfunction in patients under MMT referring to MMT clinics of Kerman, Iran. Patients and Methods: In this cross-sectional study, 198 adult subjects under MMT for more than 6 months were enrolled. Measurement tool consisted of Pittsburgh sleep quality index (PSQI), Arizona sexual experience scale (ASEX), the 12-item general health questionnaire (GHQ-12), and a demographic questionnaire. The questionnaires were self-completed, except where individuals were illiterate. Results: Mean ± SD age of the subjects was 41.2 ± 7.9 years and 93.4% of them were male. More than half of them used heroin. Prevalence of poor sleeping and sexual dysfunction in patients under MMT were 67.7% and 18.2%, respectively. There was no association between sleep quality or sexual dysfunction and demographics or methadone dose. However, a significant correlation was observed between mental health and sleep quality (r =0.16, P = 0.033), and sexual function (r = 0.18, P = 0.011). Conclusions: Sleep quality showed a poorer profile than sexual function. Therefore, more emphasis should be laid on treatment of sleep disparity during follow up of MMT patients comparing to their sexual function. Patients should be reassured that probable sexual dysfunctions should not be regarded as a consequence of MMT. PMID:26870710

    The present report is an intent-to-treat analysis involving secondary data drawn from the first randomized clinical trial of prison-initiated methadone in the United States. This study examined predictors of treatment entry and completion in prison. A sample of 211 adult male prerelease inmates with preincarceration heroin dependence were randomly assigned to one of three treatment conditions: counseling only (counseling in prison; n= 70); counseling plus transfer (counseling in prison with transfer to methadone maintenance treatment upon release; n= 70); and counseling plus methadone (methadone maintenance in prison, continued in a community-based methadone maintenance program upon release; n= 71). Entered prison treatment (p <. 01), and completed prison treatment (p< .001) were significantly predicted by the set of 10 explanatory variables and favored the treatment conditions receiving methadone. The present results indicate that individuals who are older in age and have longer prison sentences may have better outcomes than younger individuals with shorter sentences, meaning they are more likely to enter and complete prison-based treatment. Furthermore, implications for the treatment of prisoners with prior heroin dependence and for conducting clinical trials may indicate the importance of examining individual characteristics and the possibility of the examination of patient preference.

    Poor sleep quality was frequently reported by opioid dependence patients during methadone maintenance therapy (MMT). The study investigated a sample of patients on MMT to investigate the severity and prevalence of sleep problems in MMT patients. We evaluated sleep quality and disturbances of 119 Malay male patients from MMT clinics in Kelantan, Malaysia between March and July 2013 using the Pittsburgh Sleep Quality Index (PSQI)-Malay version. Patients' demographic, clinical data, past drug history and methadone treatment variables were recorded. Patients averaged 37.5 years of age (SD 6.79) and their mean age of first time illicit drug use was 19.3 years (SD 4.48). Their mean age of entering MMT was 34.7 years (SD 6.92) and the mean duration in MMT was 2.8 years (SD 2.13). The mean current daily dosage of methadone was 77.8 mg (SD 39.47) and ranged from 20 to 360 mg. The mean global PSQI score was 5.6 (SD 2.79) and 43.7% patients were identified as 'poor sleepers' (global PSQI scores >5). This study confirms the poor overall sleep quality among patients on MMT. The prevalence and severity of sleep problems in MMT patients should not be underestimated. PMID:26826835

    The aims of this study were to examine unfavorable attitudes toward receiving methadone maintenance therapy (MMT) and associated factors among inmates using intravenous heroin in Taiwan. A total of 315 inmates using intravenous heroin were recruited. Their unfavorable attitudes toward receiving MMT after discharge from prison were evaluated using the Client Attitudes Toward Methadone Programs Scale. The associations of unfavorable attitudes toward receiving MMT with sociodemographic and drug-using characteristics, human immunodeficiency virus serostatus, perceived family support, and depression were examined using multiple regression analysis. The results of this study showed that the mean score of unfavorable attitudes toward receiving MMT, determined on the Client Attitudes Toward Methadone Programs Scale, was 9.918 (standard deviation=2.277, range=5-20). Heroin-using inmates who were young, started using heroin earlier, perceived many advantages and few disadvantages of heroin use, had never received MMT, and had severe depression, had unfavorable attitudes toward receiving MMT. Based on the results of this study, we suggest that inmates who have the factors associated with unfavorable attitudes toward receiving MMT should receive intervention and motivational interviewing to improve their attitudes toward MMT and to increase their opportunity to receive MMT after discharge from prison.

    China’s methadone maintenance treatment program was initiated in 2004 as a small pilot project in just eight sites. It has since expanded into a nationwide program encompassing more than 680 clinics covering 27 provinces and serving some 242 000 heroin users by the end of 2009. The agencies that were tasked with the program’s expansion have been confronted with many challenges, including high drop-out rates, poor cooperation between local governing authorities and poor service quality at the counter. In spite of these difficulties, ongoing evaluation has suggested reductions in heroin use, risky injection practices and, importantly, criminal behaviours among clients, which has thus provided the impetus for further expansion. Clinic services have been extended to offer clients a range of ancillary services, including HIV, syphilis and hepatitis C testing, information, education and communication, psychosocial support services and referrals for treatment of HIV, tuberculosis and sexually transmitted diseases. Cooperation between health and public security officials has improved through regular meetings and dialogue. However, institutional capacity building is still needed to deliver sustainable and standardized services that will ultimately improve retention rates. This article documents the steps China made in overcoming the many barriers to success of its methadone program. These lessons might be useful for other countries in the region that are scaling-up their methadone programs. PMID:21113034

    Experience from two HIV-preventive projects among drug abusers in Oslo, Norway, shows that HIV-positive drug abusers carry on their drug abuse independent of visits to residential drug-free treatment or prison. HIV-positive former drug abusers show a tendency to relapse to drug abuse. In terms of HIV-prevention among drug abusers it is important to reduce injection of drugs among HIV-positive drug abusers. Thus, methadone maintenance programmes should be considered in HIV-prevention in Norway. PMID:2363170

    Internet addiction is known to be associated with depression. The Internet Addiction Test (IAT) and the Center for Epidemiologic Studies Depression scale (CES-D) for depression were studied among non-selective methadone maintenance treatment patients from the United States (n = 164) and Israel (n = 113). Thirty percent were not exposed to the internet, and 2.9% (n = 8) had an "occasional/frequent problem." The IAT and CES-D scores correlated significantly (p = .03). The non-exposed group was older, less educated, and had more benzodiazepine abusers. Unlike other behavioral addictions that characterized these patients, the internet addiction problem is rare, but should not be ignored. PMID:26284288

    Methadone maintenance therapy (MMT) has been found effective in treating heroin addiction. Serious consideration should be given to the modality of methadone distribution, as it influences not only treatment outcome but the attitudes of policy makers and the community, too. On one hand, the choice of take-home methadone removes the need for daily attendance at a methadone clinic, which seems to improve patients' quality of life. On the other, this method, because of its lack of supervision and the absence of strict consumption monitoring, runs the risk of methadone misuse and diversion. In this study, we compared A) supervised daily consumption, B) contingent take-home incentives and C) non-contingent take-home in methadone maintenance in three groups of heroin-addicted patients attending three different MMT programmes. Retention rates at 12 months were significantly higher in contingent take-home patients (group B) than in those with supervised daily consumption (group A) and the non-contingent take-home (group C). Retention rates were higher in group A than in group C patients. Compared to patients in groups A and B, those in group C showed fewer negative urinalyses and higher rates of self-reported diversion and episodes of crime or violence. Results indicate a more positive outcomes following take-home methadone associated with behavioural incentives and other measures that aim to facilitate treatment compliance than those following daily supervised consumption. By contrast, non-contingent take-home methadone given to non-stabilized patients is associated with a high rate of diversion, along with more crime episodes and maladaptive behaviours. PMID:21147192

    Background Dual dependence on opiate and cocaine occurs in about 60% of patients admitted to methadone maintenance and negatively impacts prognosis (Kosten et al., 2003). Topiramate (TOP) is an antiepileptic drug that may have utility in the treatment of cocaine dependence because it enhances the GABAergic system, antagonizes the glutamatergic system, and has been identified by NIDA as one of only a few medications providing a “positive signal” warranting further clinical investigation. (Vocci and Ling, 2005). Method In this double-blind controlled clinical trial, cocaine dependent methadone maintenance patients (N=171) were randomly assigned to one of four groups. Under a factorial design, participants received either TOP or placebo, and monetary voucher incentives that were either contingent (CM) or non-contingent (Non-CM) on drug abstinence. TOP participants were inducted onto TOP over 7 weeks, stabilized for 8 weeks at 300 mg daily then tapered over 3 weeks. Voucher incentives were supplied for 12 weeks, starting during the fourth week of TOP induction. Primary outcome measures were cocaine abstinence (Y/N) as measured by thrice weekly urinalysis and analyzed using Generalized Estimating Equations (GEE) and treatment retention. All analyses were intent to treat and included the 12-week evaluation phase of combined TOP/P treatment and voucher intervention period. Results There was no significant difference in cocaine abstinence between the TOP vs P conditions nor between the CM vs Non-CM conditions. There was no significant TOP/CM interaction. Retention was not significantly different between the groups. Conclusion Topiramate is not efficacious for increasing cocaine abstinence in methadone patients. PMID:24814607

    Abstract Background The aim of this study was examination the relationship between mindfulness and drug craving in addicts undergoing methadone maintenance treatment. Methods The subjects of this research were 80 addicts undergoing methadone maintenance treatment selected through available sampling from four addiction treatment center in Ahvaz from March 2012 to September 2012. Two questionnaires to examine the variables of this study were the five facets mindfulness questionnaire (FFMQ) and hero-in craving questionnaire (HCQ). The data were analyzed using SPSS version 16. Results The Pearson correlational results indicated significant reverse relation between mindfulness factors and craving sub scales (P<0.05). Besides, the regression results indicated that four factors of mindfulness such as observation, describing, acting with awareness and non-reactivity to inner experience can totally predict 48 percent of craving variance (P<0.01 ). Conclusion There is a reverse relation between mindfulness and craving. Therefore we advise the researchers in addiction fields that in line with various studies that indicated effectiveness of mindfulness based interventions in improving various psychological problems, be researcher in effectiveness of this intervention in addiction fields. Moreover, we advise the addiction therapists to use mindfulness based interventions and technics in order to reduction of emotional and cognitive problems co morbidities with addiction such as craving that is one of potential factors affecting survival and relapse to drug abuse.

    The objective of this study was to determine what sociodemographic, lifestyle, or drug-related characteristics predict temporal changes in self reported drug injection frequencies among HIV-seronegative injection-drug users (IDUs) who were being given HIV testing and risk reduction counseling. The 277 subjects were given 4-11 quarterly interviews including detailed history of drug use and other HIV risk factors, HIV risk reduction counseling, and venipuncture for HIV antibody testing. A regression slope of change over time in drug injection frequency was calculated for each subject, and categories were created of decreasing temporal slope, increasing slope, relapse (decrease initially, then increase), or no substantial change. Only 44% of subjects decreased their drug injection frequencies despite repetitive HIV testing and counseling. In multivariate logistic analyses, decreasing temporal trends were associated with consistent enrollment in methadone maintenance (p < .1), whereas increasing trends conversely were associated with inconsistent enrollment (p < .01) and also with an absence of crack use (p < .01). Relapses were significantly associated with needle sharing with multiple partners and a low frequency of smoking. The data suggest that methadone maintenance facilitates a positive response to HIV risk reduction counseling. However, the fact that only a minority of subjects displayed a decreasing temporal trend in drug injection frequencies emphasizes the need for improved therapeutic and counseling techniques.

    Background: Methadone is a synthetic opioid, used in treatment of chronic pains. The current study was carried out to evaluate the QTc interval in Iranian causalities (Janbazan) of Iran-Iraq war receiving maintenance methadone treatment. Materials and Methods: In 2010, one hundred war causalities in Isfahan who chronically take daily dose of 20 mg or more of methadone (more than 2 weeks), and did not have the history of cerebrovascular or coronary artery diseases, cardiac pacemaker, congenital prolonged QTC, or taking drugs affecting QTc, or having electrolyte abnormalities, were selected for the study. An electrocardiogram was taken from each patient using cardiofax instrument, and QTC was calculated manually. The data was analyzed using SPSS software with descriptive statistical methods and Pearson's correlation coefficient. Findings: All patients were male and had the mean age of 45.6 ± 6.1 years. The patients received 20-240 mg methadone daily for 1 to 108 months. The QTc was prolonged in 25% of the patients (QTc 5 450 ms), with the mean of 472.72 ± 18.5 ms (range 450-508 ms) and the mean daily dose of methadone 85.2 ± 59.0 mg. No significant relationship was observed between QTC interval on the one hand, and methadone dose (R = 0.025, P = 0.8), duration of treatment (R =-0.048, P = 0.68), age (R = 0.037, P = 0.71), and weight (R = 0.1, P = 0.21) of the patients, on the other hand. None of the patients had faint, syncope, arrhythmia, or sudden death. Conclusion: Oral methadone causes prolongation of QTC interval. However, the dosage of methadone and duration of treatment were not statistically related to QTC interval. PMID:23267379

    Objectives: This study aimed to compare the QTc interval between low and high dose methadone groups and evaluate the pattern of QTc variation. Methods: This is a prospective cohort study conducted from December 2010 till August 2011 at Malaysian University of Science’s Hospital. Forty six subjects, grouped in high dose (>80mg) and low dose (<80mg) oral methadone, were followed-up at 4-weekly for QTc measurements. Relevant demographic and biochemical profiles were taken at intervals with concurrent QTc measurements. Results: No significant QTc differences between methadone dosage groups were found at Week 0 (434ms vs 444ms, p = 0.166) and week 8 (446.5ms vs 459ms, p = 0.076), but not at week 4(435ms vs 450ms, p = 0.029). However, there were significant associations between the groups with QTc prolongation at week 0 and 4 (OR 4.29(95% CI 1.01, 18.72) p=0.044 and OR 5.18 (95% CI 1.34, 20.06) p =0.013, respectively) but not at week 8 (OR 2.44 (95% CI 0.74, 8.01) p=0.139). On multivariate analysis, dose group was the sole significant factor for QTc prolongation for week 0 and 4 (p values 0.047 and 0.017, respectively), but not at week 8. Conclusion: High-dose methadone group is more likely to develop prolonged QTc than low-dose group. However, such effects were inconsistent and occurred even during chronic methadone therapy, mandating judicious QTc and serum methadone monitoring. PMID:24353706

    Aims Despite proven benefits of antiretroviral therapy (ART), many HIV-infected injection drug users (IDU) do not access treatment even in settings with free health care. We examined whether methadone maintenance therapy (MMT) increased initiation and adherence to ART among an IDU population with free health care. Design We prospectively examined a cohort of opioid-using antiretroviral-naïve HIV-infected IDU and investigated factors associated with initiation of antiretroviral therapy as well as subsequent adherence. Factors independently associated with time to first initiation of antiretroviral therapy were modelled using Cox proportional hazards regression. Findings Between May 1996 and April 2008, 231 antiretroviral-naïve HIV-infected opioid using IDU were enrolled, among whom 152 (65.8%) initiated ART, for an incidence density of 30.5 (95% confidence interval [CI]: 25.9–35.6) per 100 person-years. After adjustment for time-updated clinical characteristics and other potential confounders, use of MMT was independently associated with more rapid uptake of antiretroviral therapy (relative hazard = 1.62 [95% CI: 1.15–2.28]; p = 0.006). Those prescribed methadone also had higher rates of ART adherence after first antiretroviral initiation (odds ratio = 1.49 [95% CI: 1.07–2.08]; p = 0.019). Conclusion These results demonstrate that MMT contributes to more rapid initiation and subsequent adherence to ART among opioid-using HIV-infected IDU. Addressing international barriers to the use and availability of methadone may dramatically increase uptake of HIV treatment among this population. PMID:20331553

    Background China has recently adopted methadone maintenance treatment (MMT) as a national strategy to address the problem of drug abuse and related public health issues such as HIV and HCV infections. However, low enrollment and retention rates suggest that barriers may exist in MMT utilization. This study examined both patients’ perceptions and service providers’ perceptions of challenges in MMT implementation in China. Methods Four focus groups were conducted in two Chinese cities, Shanghai and Kunming, to explore the perceived and experienced barriers in MMT participation in China. All focus group discussions with participants were audio taped and transcribed. Atlas.ti 5.1 was used to analyze data. Results Service providers and patient participants reported positive experiences (e.g. effects of MMT in curbing withdrawal symptoms) but also expressed concerns about side effects and continued heroin use during MMT. They also identified barriers in participating and remaining in MMT, including affordability (fee requirement), acceptability (methadone as a substitution, dose, long-term nature), accommodation and accessibility (inconvenient operation hours, lack of transferability to other MMT clinics during travel) and competition between public health and public security. Conclusions The present findings have implications for reconsidering the current MMT policies and practices in order to improve access, utilization and, ultimately, the effectiveness of MMT in China.

    Methylphenidate, an amphetamine-like prescription medication for attention deficit hyperactivity disorder (ADHD) was suspected as being abused among methadone maintenance treatment (MMT) patients. We tested its presence in the routine urine monitoring of all patients in both Tel Aviv and Las Vegas MMT clinics. Data on demographic and addiction history, ADHD (Wender Utah Rating Scale), cognitive impairment (Mini Mental State Exam), and lifetime DSM-IV-TR psychiatric diagnosis from admission were retrieved, and retention following 6 months. None of the 190 patients in Las Vegas tested positive for methylphenidate, while 14.7% (45/306) did in Tel Aviv. Abusers were less educated (p = 0.01), had higher ADHD scores (p = 0.02), lower cognitive scores (p = 0.05), and a higher benzodiazepine (BDZ) abuse rate (p < 0.0005), with no difference in age, gender, duration in MMT, cannabis, opiates, and cocaine abuse and infectious disease. Of the methylphenidate abuse 42.2% have take-home methadone dose privileges. Not like opiate use, being methylphenidate positive did not relate to 6-months retention. Compared to Tel Aviv, Las Vegas patients were more educated, with lower BDZ, and cocaine abuse. The greater abuse of methylphenidate among ADHD subjects might indicate their using it as self-medication, raising a possible indication for its prescription for that subgroup of MMT patients. The high rate of methylphenidate abuse in Israel needs future study. PMID:25605438

    Whether methadone maintenance treatment (MMT) can improve the basal function of the hypothalamic–pituitary–adrenal (HPA) axis, which is suppressed by long-term heroin consumption, is a matter of debate. The stress state and depression and anxiety symptoms may affect the basal activity of the HPA axis in MMT patients. However, the effect of psychological factors on HPA activity was not simultaneously controlled in previous studies. This study investigated differences in HPA basal activity between MMT patients and controls using psychological variables as covariates. The participants included 52 MMT patients and 41 age-matched, non-heroin-dependent controls. Psychological states were self-reported with the Perceived Stress Scale, Self-Rating Depression Scale and Self-Rating Anxiety Scale. The hair cortisol level was adopted as a biomarker of HPA basal activity and was determined with liquid chromatography tandem mass spectrometry. The results revealed that MMT patients had significantly higher hair cortisol levels than the controls (p<0.05), but the difference was not significant (p>0.05) when the perceived stress, depression and anxiety scores were used as covariates. We concluded that patients with long-term MMT showed higher basal activity of the HPA axis. The high chronic stress state and increase in depression and anxiety symptoms may mask the suppression effect of methadone on the HPA activity. PMID:27010803

    Vietnam is among the countries with the highest rate of HIV transmission through injecting drug users. HIV prevalence among injecting drug users is 20% and up to 50% in many provinces. An estimated number of drug users in the country by the end of 2011 were 171,000 in which the most common is heroin (85%). Detoxification at home, community, and in rehabilitation centers have been the main modalities for managing heroin addiction until Methadone Maintenance Treatment (MMT) was piloted in 2008. Recent reports have demonstrated positive treatment outcomes. Incidence of HIV was found remarkably low among patients on MMT. Treatment has significantly improved the quality of life as well as stability for society. The government has granted the Ministry of Health (MoH) to expand Methadone treatment to at least 30 provinces to provide treatment for more than 80,000 drug users by 2015. The Vietnam Administration for HIV/AIDS Control (VAAC) and MOH have outlined the role and responsibility of key departments at the central and local levels in implementing and maintaining MMT treatment. This paper will describe the achievements of the MMT pilot program and the scaling-up plan as well as strategies to ensure quality and sustainability and to overcome the challenges in the coming years.

    To view methadone maintenance treatment (MMT) globally, it is necessary to accumulate data on MMT policy implementation under different health service systems. The aim of the current study is to provide empirical evidence about policy implementation of MMT and HIV infection control, as well as recommendations for improvement of MMT in the future. Based on China's national policy framework of MMT, policy implementation of MMT in Hubei province has two objectives: 1) to create linkages between health and public security, and 2) to provide integrated services for management of drug abusers. From 2007 to 2011, following the establishment of MMT clinics that provide methadone as well as HIV prevention services, the proportion of HIV infection among drug abusers decreased relatively quickly (12.12% → 5.77% → 5.19% → 2.39% → 2.04%). However, high drop-out rate and poor information management have been identified as particular problems which now need to be addressed. Furthermore, client drop-out from MMT programs may reflect social issues the clients encounter, and consequently, sustainable MMT development requires incorporation of social measures that help MMT clients return to society without discrimination, especially through family cooperation and employment opportunities.

    Abnormal interhemispheric functional connectivity is attracting more and more attention in the field of substance use. This study aimed to examine 1) the differences in interhemispheric functional connections of the insula with the contralateral insula and other brain regions between heroin users under methadone maintenance treatment (MMT) and healthy controls, and 2) the association between heroin users' interhemispheric insular functional connectivity using resting functional magnetic resonance imaging (fMRI) and the results of urine heroin analysis. Sixty male right-handed persons, including 30 with heroin dependence under MMT and 30 healthy controls, were recruited to this study. Resting fMRI experiments and urine heroin analysis were performed. Compared with the controls, the heroin users had a significantly lower interhemispheric insular functional connectivity. They also exhibited lower functional connectivity between insula and contralateral inferior orbital frontal lobe. After controlling for age, educational level and methadone dosage, less deviation of the interhemispheric insula functional connectivity was significantly associated with a lower risk of a positive urine heroin analysis result. Our findings demonstrated that the heroin users under MMT had abnormal long-range and interhemispheric resting functional connections. Those with a less dysfunctional interhemispheric insula functional connectivity had a lower risk of a positive urine heroin test. PMID:27497215

    130 patients from a methadone maintenance treatment program agreed to complete Symptoms Checklist 90-Revised (SCL-90R) and Alcohol Use Disorders Identification Test (AUDIT) self-report scales. Scores higher than the proposed cut-score on SCL-90R scale were observed on depression, obsessions-compulsions, paranoid ideation, anxiety, anger-hostility, somatization, interpersonal sensitivity, and psychoticism subscales. In sum, 42.9% of our sample exhibited depressive symptomatology, 34.9% obsessive-compulsive symptoms, 29.1% somatization, 27.2% anxiety symptoms, 22.2% paranoid ideation, 19% phobic anxiety, 15.1% psychoticism, and 15.1% hostility and 11.9% presented with symptoms of interpersonal sensitivity. Mean score on AUDIT scale was 6.9 ± 7.9. 63.0% of our participants scored below cut-off and were classified as having a low level of alcohol-related problems; 24.4% scored in the range of 8–15 which is an indication of alcohol abuse whereas 12.6% scored 16 and above indicative of serious abuse/addiction. Scores on AUDIT scale were positively correlated with length of time on methadone treatment, but not with length of time on drug use or age of our participants. Positive correlations were observed among AUDIT and SCL-90R scores, namely, with global severity index score, positive symptom distress index, positive symptom total, and all primary symptom dimensions subscales except phobic anxiety.

    The aims were to identify predictors of treatment retention in an Israeli methadone maintenance treatment (MMT) clinic, and to compare the findings to other international settings. We prospectively studied 492 patients admitted since 1993 through 10 years to an Israeli MMT clinic associated with a university-affiliated tertiary care medical center. Analyses (Kaplan Meier and Cox regression) included methadone dose and urinalysis results (for methadone, cocaine, opiates, benzodiazepines, THC, amphetamines) of each patient in the first month and after 1 year in treatment (or during the last month if the stay was >3 months and <1 year) and patients' characteristics (modified ASI). The 1-year retention rate was 74.4%; 65.8% stopped opiate abuse after 1 year in treatment. On admission, 13.6% of patients had used cocaine: there was a net decrease of 61.6% after 1 year. Factors predicting prolonged retention in MMT treatment (Cox regression) were daily methadone dose of 100mg or greater, negative urine for opiates after 1 year, and being a parent on admission. We conclude that our good outcome results (high rate of retention after 1 year (74.4%), high proportion of opiate abuse cessation (65.8%), and net reduction in cocaine abuse, similar to normal standards in other MMT clinics elsewhere in the world, justify the expansion of the MMT clinic network in Israel in order to make treatment available to all those who need it. A protocol favoring higher methadone dosage as appropriate is recommended. PMID:16219428

    This cross-sectional study examines predictors of heavy smoking among 256 male and female methadone maintenance therapy (MMT) clients from five MMT clinics in the Los Angeles area. The authors find that women report lower rates of heavy smoking than men (47% vs. 54%, respectively), in concordance with current literature pointing to gender differences in smoking behaviors. In particular, men who report heavy drinking, fair or poor health, and recent heroin use are more likely to report heavy smoking compared with men not reporting these factors. Women who report recent heroin use, a lifetime history of sex trade, and who have been ill enough to require a blood transfusion also have greater odds of reporting heavy cigarette smoking. Findings from this study may aid not only in designing gender-based smoking cessation programs for MMT clients but also in addressing the gender-based issues related to smoking in such a population.

    Hepatitis C virus (HCV) knowledge, attitudes, beliefs, and experiences (KABE) of 64 HCV antibody positive methadone maintenance treatment (MMT) patients were assessed in conjunction with acceptability of an on-site semi-structured HCV education session, HCV RNA diagnostic testing, HCV treatment motivational assessment, and initiation of HCV treatment. The KABE interviews were conducted in 2006 and 2007 in an urban New York State MMT clinic in affiliation with a NIDA-funded HCV research project. The majority had basic knowledge of HCV disease, but poor understanding of HCV testing and treatment. While the majority of participants expressed fear of HCV treatment side effects, 88% accepted HCV RNA testing and 78% expressed willingness to start HCV treatment with the majority of chronically infected choosing to start HCV treatment medications. Study limitations and implications are discussed. PMID:20141461

    This study sought to: (1) determine the prevalence of gambling disorder using the Diagnostic and Statistical Manual of Mental Disorders Version 5 (DSM-5; American Psychiatric Association in Diagnostic and statistical manual of mental disorders, American Psychiatric Publishing, Arlington, 2013) criteria; (2) identify the frequency and amount of money spent on gambling behaviors; and (3) determine demographic and treatment related predictors associated with gambling disorder in a substance using population. People receiving methadone maintenance treatment (N = 185) in an urban medical center consented to participate in the study. We used DSM-5 criteria to assess the 12-month prevalence of gambling disorder. Questions adapted from a previously developed measure were used to identify, describe and quantify the frequency of use and amount of money spent on gambling behaviors. Most participants were African-American (71.4 %), male (54.1 %), unmarried (76.8 %), unemployed (88.1 %) and had an income of <$20,000 (88.5 %). On average, participants were receiving 81.0 mg of methadone (SD: 22.8) daily. Nearly half (46.2 %) of participants met DSM-5 criteria for gambling disorder. Compared to those without gambling disorder, those with gambling disorder did not differ significantly with respect to demographic characteristics nor methadone dose. However, those with gambling disorder had been in methadone maintenance treatment for significantly less time. Those with gambling disorder were significantly more likely to report engaging in a variety of gambling behaviors. Given that the 12-month prevalence of DSM-5 defined gambling disorder was nearly 50 % future efforts to screen and treat gambling disorder in the context of methadone maintenance treatment are clearly warranted.

    Setting: Thirteen methadone maintenance treatment (MMT) clinics across Yunnan, the province with the highest human immunodeficiency virus (HIV) burden in China. Objectives: To determine, among HIV-negative participants on MMT, the proportion lost to follow-up (defined as those who missed the 6-monthly follow-up examination), factors associated with loss to follow-up (LFU), HIV seroconversion rate and factors associated with seroconversion. Design: Prospective cohort study from October 2008 to April 2011. All participants were administered a pre-tested structured questionnaire to capture associated factors and offered HIV testing every 6 months. χ2 test and log-binomial regression were used for data analysis. Results: Of 1146 participants, 541 (47%) were lost to follow-up in 2.5 years. Factors associated with higher LFU proportion include <6 months of previous MMT, inconvenient location of the MMT clinic and average methadone dose ⩽60 mg/day, with adjusted relative risks (RRs) of respectively 1.4 (95%CI 1.2–1.5), 1.2 (95%CI 1.0–1.4) and 1.1 (95%CI 1.0–1.3). The overall HIV seroconversion rate was 6.6 (95%CI 3.7–11.0) per 1000 person-years. Not living with a partner contributed to higher HIV rates, with an adjusted RR of 3.6 (95%CI 1.0–12.8). Conclusion: The retention rate of MMT participants in Yunnan was not satisfactory. Decentralising service delivery in the community and making directly observed treatment more convenient has the potential to improve retention. PMID:26423758

    Despite the high prevalence of hepatitis C virus (HCV) infection among drug users enrolled in methadone maintenance treatment programs, few drug users are being treated with combination therapy. The most significant barrier to treatment is lack of access to comprehensive HCV-related care. We describe a pilot program to integrate care for HCV infection with substance abuse treatment in a setting of maintenance treatment with methadone. This on-site, multidisciplinary model of care includes comprehensive screening and treatment for HCV infection, assessment of eligibility, counseling with regard to substance abuse, psychiatric services, HCV support groups, directly observed therapy, and enhanced linkages to a tertiary care system for diagnostic procedures. Our approach has led to high levels of adherence, with liver biopsy and substantial rates of initiation of antiviral therapy. Two cases illustrate the successful application of this model to patients with HCV infection complicated by active substance abuse and psychiatric comorbidity. PMID:15768345

    Experiences of stigma from others among people with a history of drug addiction are understudied in comparison to the strength of stigma associated with drug addiction. Work that has studied these experiences has primarily focused on stigma experienced from healthcare workers specifically even though stigma is often experienced from other sources as well. Because stigma has important implications for the mental health and recovery efforts of people in treatment, it is critical to better understand these experiences of stigma. Therefore, we characterize drug addiction stigma from multiple sources using qualitative methodology to advance understandings of how drug addiction stigma is experienced among methadone maintenance therapy patients and from whom. Results demonstrate that methadone maintenance therapy patients experience prejudice, stereotypes, and discrimination from friends and family, coworkers and employers, healthcare workers, and others. Discussion highlights similarities and differences in stigma experienced from these sources. PMID:23956702

    Objective Methadone maintenance treatment (MMT) was introduced to China in 2004 to reduce the harm of injecting drug users (IDUs). However, little is known about continued drug use, especially methamphetamine (MAMP), among MMT patients. Methods A survey was conducted among patients attending five major MMT clinics in Dehong Prefecture in 2014 to investigate the heroin and MAMP use and their associated risk factors. Participants were administered with face-to-face interviews, and urine tests for morphine and MAMP. Results A total of 2,121 were eligible and participated in the study. Among them, 220 (10.4%) were only positive for morphine, 12.9% were only positive for MAMP, and 196 (9.2%) were positive for both morphine and MAMP. Compared with neither use of heroin nor MAMP during MMT, heroin use (not using MAMP) was associated with ethnicity, shorter duration of MMT, lower dose of methadone, and having had no more than two sex partners in the past year; MAMP use (not using heroin) was associated with ethnicity, longer duration of MMT, higher dose of methadone and being aged <30 years (vs. ≥50 years); use of both heroin and MAMP was associated with being Dai minority (vs. Han), a marital status of divorced or widowed, having used drugs for ≥10 years and shorter duration of MMT. Conclusion These findings indicate the complexity in the treatment of heroin users and underscore the importance in prescribing appropriate methadone dosages in order to reduce both heroin and MAMP use.

    Although it is well established that methadone can be an effective treatment for opiate addiction, it is not clear how methadone maintenance affects cocaine use and cravings in individuals who self-administer both opiates and cocaine. In our attempt to explore the effect of methadone maintenance on the effects of cocaine, we first assessed the locomotor stimulatory effects of cocaine in rats maintained on methadone (0, 10, 20, or 30 mg/kg/day, via osmotic minipumps). Chronic methadone elevated baseline locomotion in a dose-dependent manner and did not reduce the direct stimulatory effects of cocaine (5 mg/kg). We then investigated the effects of the highest methadone maintenance dose (30 mg/kg/day) on heroin and cocaine seeking in extinction, and when it was precipitated by exposure to heroin, cocaine, or foot-shock stress in rats trained to self-administer both drugs in the same experimental context (heroin 0.05 mg/kg/inf; cocaine 0.5 mg/kg/inf, eight 3-h sessions each). In tests of reinstatement, rats responded selectively on the appropriate drug-associated lever after priming injections of heroin (0.25 mg/kg) or cocaine (20 mg/kg). Methadone maintenance blocked both cocaine- and heroin-induced reinstatement, but not stress-induced reinstatement, which was not lever selective. These results suggest that although methadone maintenance may not reduce the direct stimulatory effects of cocaine, it has the potential to reduce both spontaneous and cocaine-primed cocaine-seeking behavior.

    Background: Opioid use disorder is a serious international concern with limited treatment success. Men and women differ in their susceptibility to opioid use disorder and response to methadone treatment and can therefore benefit from sex-specific treatment. We performed a systematic review of the literature on outcomes of methadone maintenance treatment for opioid use disorder in men and women related to drug use, health status and social functioning. Methods: We searched PubMed, Embase, PsycINFO and CINAHL for observational or randomized controlled studies involving adults 18 years of age or older undergoing methadone treatment for opioid use disorder. Studies were included if they investigated sex differences in methadone treatment outcomes. Two authors independently reviewed and extracted data. Meta-analyses were performed when possible; risk of bias and quality of evidence were also assessed. Results: Twenty studies with 9732 participants were included, of which 18 were observational and 2 were randomized controlled trials. Men and women differed significantly in alcohol use (odds ratio [OR] 0.52, 95% confidence interval [CI] 0.31 to 0.86), amphetamine use (OR 1.47, 95% CI 1.12 to 1.94), legal involvement (OR 0.63, 95% CI 0.47 to 0.84) and employment during treatment (OR 0.39, 95% CI 0.21 to 0.73). Opioid use patterns were similar among men and women. Risk of bias was moderate, and quality of evidence was generally low. Interpretation: Sex differences were evident in polysubstance use, legal involvement and employment status among men and women receiving methadone treatment for opioid use disorders. Although the quality of evidence was low, our review highlights the need for improved implementation of sex-specific treatment strategies. PMID:26457294

    Background Using methadone maintenance therapy (MMT) clinics to deliver antiretroviral therapy (ART) is an effective strategy to promote treatment initiation and adherence for HIV-positive drug users. This paper describes the implementation barriers perceived by service providers for an intervention pilot designed to integrate ART services in MMT clinics. Methods The study was conducted in six MMT clinics in Sichuan province, China. Two service providers selected from each of the six clinics underwent training in administering ART. The trained providers delivered ART-related services in their clinics. A focus group was conducted among the service providers to assess their experiences and perceived challenges in delivering integrated services. Results Barriers at policy, institutional, provider, and client levels were identified. Policy level barriers included household registration restrictions and a lack of insurance coverage for testing expenses. Inefficient coordination between treatment sites and MMT clinics was an obstacle at the institutional level. Insufficient training and added workload were barriers at the provider level. Finally, conflict with daily dosing habits was identified as the primary reason that clients did not accept ART. Conclusion Although integrating ART into MMT clinics is beneficial, multilevel barriers to implementation need to be addressed. This study documents the need for treatment transferability and insurance coverage, protection of client confidentiality, proper provider training, coordination with treatment sites, and individualized ART service for MMT clients.

    This study identifies structural-level factors influencing methadone maintenance therapy (MMT) program implementation in China. Twenty-eight service providers and 560 randomly selected clients from 28 MMT clinics in the study area underwent face-to-face interviews. Number of clients, retention rate, coverage, and structural-level factors were collected from a survey of service providers. Individual-level factors and self-reported illicit drug use information were obtained from clients. Urine specimens were collected from the client participants to test for heroin use. Clinics affiliated with the local Centers for Disease Control and Prevention (CDC) had more clients, higher retention rates, and broader coverage than those not affiliated with the CDC. Longer operating hours, incentive for compliant clients, and comprehensive services were positively associated with client recruitment and coverage. Comprehensive services and incentives for compliant clients were negatively associated with concurrent illicit drug use. Comprehensive services should be incorporated into the MMT program. Extended operating hours and incentives for compliant clients should be implemented. PMID:20015606

    This study analyzed indicators of alcohol-related problems in opiate addicts before, during, and after leaving methadone maintenance treatment (MMT), in relation to illicit drug use and retention in treatment. The study was based on 204 patients, admitted to MMT for the first time between 1 January 1995 and 31 July 2000, and followed until 31 December 2000. Three measures were used to indicate alcohol use and alcohol-related problems; records of hospital care with an alcohol-related diagnosis, any treatment with alcohol-sensitizing drugs (disulfiram or calcium carbimide) during MMT, and results of the 5-hydroxytryptophol to 5-hydroxyindoleacetic acid ratio (5HTOL/5HIAA) in urine, a sensitive biomarker for recent drinking. Use of illicit drugs was determined by routine urine drug testing. About one third of the patients (n = 69) had a lifetime prevalence of hospital treatment for an alcohol-related diagnosis, 45 of whom had been hospitalized (mean 4.2 stays) prior to the start of MMT. There was a significant association (p<0.05) between the number of alcohol-related diagnoses prior to treatment and a positive 5HTOL/5HIAA test during MMT. The alcohol indicators first became positive on average 1.6 years after admission to treatment, compared with after about 4 months for illicit drugs. Use of cannabis or benzodiazepines was significantly associated with alcohol use. Female methadone patients with indications of alcohol-related problems relapsed more often into illicit drug use than did women without such indications (3.9 vs. 2.5 relapse periods/year; p<0.005), whereas no significant association was found for men. The results of the present study indicate that drinking problems among patients undergoing MMT is associated with an increased risk of relapse into illicit drug use and with discharge from treatment. Concurrent treatment of alcohol-related problems, including systematic monitoring of alcohol use, therefore should be recommended to reduce the risk for relapse

    In an effort to enhance patient safety in Opioid Treatment Programs (OTPs), the Substance Abuse and Mental Health Services Administration (SAMHSA) convened a multi-disciplinary Expert Panel on the Cardiac Effects of Methadone. Panel members reviewed the literature, regulatory actions, professional guidances, and OTPs’ experiences regarding adverse cardiac events associated with methadone. The Panel concluded that, to the extent possible, every OTP should have a universal Cardiac Risk Management Plan (incorporating clinical assessment, ECG assessment, risk stratification, and prevention of drug interactions) for all patients, and should strongly consider patient-specific risk minimization strategies (such as careful patient monitoring, obtaining ECGs as indicated by a particular patient’s risk profile, and adjusting the methadone dose as needed) for patients with identified risk factors for adverse cardiac events. The Panel also suggested specific modifications to informed consent documents, patient education, staff education, and methadone protocols. PMID:22026519

    Background Methadone substitution therapy is an effective harm reduction treatment method for opioid dependent persons. Ability to retain patients in methadone treatment is an accepted predictor of treatment outcomes. Objectives The current study evaluates the roles of psychiatric comorbidity, medical comorbidity, and sociodemographic characteristics as predictors of retention in methadone treatment utilizing retrospective analysis of data from a nationwide sample of patients in methadone treatment in the VA. Methods Data were gathered using the VA’s national health services use database. A cohort of veterans with a new episode of “opiate substitution” in fiscal year 1999 was identified, and their continuous service use was tracked through fiscal year 2002. The sample included a total of 2,363 patients in 23 VA medical centers. Survival analysis was used to explore factors associated with retention in methadone treatment. Results Younger age, having a serious mental illness, being African American, or having race recorded as unknown were associated with lower rates of retention in methadone treatment programs in this population of veterans (controlling for site). Conclusion Given that extended methadone treatment is associated with improved outcomes while patients remain in treatment, more longitudinal studies using primary data collection are needed to fully explore factors related to retention. For the VA population specifically, further research is necessary to fully understand the relationship between race/ethnicity and treatment retention. Scientific Significance This is the first retention study the authors are aware of that utilizes data from a nationwide, multisite, population of participants in methadone treatment. PMID:20465373

    This study evaluated the long-term effects of different psychosocial intervention models in methadone maintenance treatment (MMT) in Xi'an China. Patients from five MMT clinics were divided into three groups receiving MMT only, MMT with counseling psychology (CP) or MMT with contingency management (CM). A five-year follow-up was carried out with daily records of medication, monthly random urine morphine tests, and tests for anti-HIV and anti-HCV every six months. Drug use behavior was recorded six months after initial recruitment using a survey. Adjusted RRs and their 95% confidence intervals (CIs) were estimated using an unconditional logistic regression model or a Cox proportional hazard model. A total of 2662 patients were recruited with 797 in MMT, 985 in MMT with CP, and 880 in MMT with CM. Following six months of treatment, the injection rates of MMT with CP and MMT with CM groups were significantly lower than that of MMT (5.1% and 6.9% vs. 16.3%, x²  =  47.093 and 29.908, respectively; P<0.05). HIV incidences for MMT, MMT with CP and MMT with CM at the five year follow-up were 20.09, 0.00 and 10.02 per ten thousand person-years, respectively. HCV incidences were 18.35, 4.42 and 6.61 per hundred person-years, respectively, demonstrating that CP and CM were protective factors for HCV incidence (RR  =  0.209 and 0.414, with range of 0.146-0.300 and 0.298-0.574, respectively). MMT supplemented with CP or CM can reduce heroin use and related risk behaviors, thereby reducing the incidence of HIV and HCV. PMID:24498406

    Mental health problems are prevalent among drug users. Methadone maintenance treatment (MMT) is an evidence-based effective treatment for drug addiction; however, there are few studies investigating depression, suicidal ideation, and their related factors among MMT users. In this cross-sectional study, 648 MMT users were recruited from six MMT clinics in Guangzhou, China. Data were collected through face-to-face interviews by trained interviewers. Of all participants, 270 (42.7%) exhibited probable depression (Depression Subscale of the Chinese short version of Depression, Anxiety, and Stress Scale (DASS-D), score ≥ 10) and 99 (15.3%) reported having suicidal ideation in the last six months. After adjusting for significant socio-demographic characteristics, all studied variables, including drug use history, social support, family support for MMT use, and satisfaction toward MMT services were significantly associated with both probable depression and suicidal ideation in the last six months. Furthermore, depression fully mediated the associations between drug use history, satisfaction toward MMT services, and suicidal ideation. In the final multivariate models, probable depression was associated with social support (OR = 0.88, 95% CI = 0.83-0.93) and satisfaction toward MMT services provided by doctors (OR = 0.59, 95% CI = 0.40-0.86), while for suicidal ideation, social support (OR = 0.85, 95% CI = 0.78-0.92) and probable depression (OR = 5.94, 95% CI = 3.39-10.42) were significant. The findings suggest that there are unmet mental health needs among MMT users. For countries with limited resources of psychological services, mental health care toward MMT users should be implanted into current health care settings and incorporate components such as social support, family's understanding of MMT, and service satisfaction.

    The aim of this study was to assess the prevalence of a history of sexual abuse and its relation to psychiatric comorbidity among former opiate addicts currently on methadone maintenance treatment (MMT). We evaluated the history of sexual abuse and current clinical obsessive compulsive disorder (OCD), dissociative identity disorder (DID), and complex posttraumatic distress disorder (cPTSD), and administered the Life Events Inventory Questionnaire among 125 MMT patients (76 females and 49 males). Eighty (64%) patients had experienced sexual abuse, 69 (55.2%) met the criteria for clinical OCD, 20 (16.0%) for cPTSD and 13 (10.4%) for DID. More females had clinical OCD than males (63.2% vs. 42.9%, respectively, p=0.03). Sexually abused patients had higher rates of clinical OCD than their non-abused counterparts (67.5% vs. 33.3%, respectively, p<0.0005) and a higher mean number of negative life events (8.0±2.0 vs. 7.1±1.8, p=0.01). Sexually abused patients showed a trend towards a higher Dissociative Experiences Scale score (17.6±10.1 vs. 14.6±8.1, p=0.08) and rate of DID (13.8% vs. 4.4%, p=0.1), but no significant difference in the rate of cPTSD (17.5% vs. 13.3%, p=0.6) compared to non-abused subjects. The 80 sexually abused patients were mostly female (85%), and 57.5% of them were abused by a family member. In summary, more sexually abused MMT patients were diagnosed with clinical OCD and fewer with cPTSD and DID. Those with cPTSD were characterized by more negative life events, higher dissociation scores, and assaults by a family member. We conclude that sexually abused MMT patients should be screened for clinical OCD. PMID:22564825

    BACKGROUND: In order to improve the delivery of health services for chronic medical conditions in our methadone clinic, we added an onsite health screening and brief health counseling to the treatment plans for patients receiving methadone maintenance treatment at the Atlanta Veterans Affairs Medical Center (VAMC). We then conducted a follow up retrospective chart review to assess whether this intervention improved health outcome for those patients. METHODS: We reviewed the charts of one hundred and two patients who received treatment at Atlanta VAMC methadone clinic between 2002 and 2008. We sought to determine whether our increased health education and screening intervention was associated with improved: 1) Improved drug addiction outcome (as measured by comparing percentage of opiate and cocaine positive drug screens from admission to most recent). 2) Basic health screening, (as measured by the patient's compliance with primary care physicians (PCP) appointments and current smoking status). 3) Management of co-occurring medical conditions (as measured by levels of LDL cholesterol, hemoglobin A1c, and systolic blood pressure (SBP). 4) Presence of QTc prolongation (difference in QTc between baseline and most recent EKG). RESULTS: Illicit drug use (opiate and cocaine) markedly decreased in patients overall. The effect was more robust for those successfully "retained" (n=55, p<0.0001) in treatment, compared to those who "dropped out" (n=40, p=0.05) of treatment. Compliance with PCP appointments was high (82% and 88% before and after the onsite intervention, respectively) for "retained" patients. LDL cholesterol level was within normal range for all patients. A1c improved by 40% after the onsite intervention as reflected by the decreased percentage of patients with A1c > 7 % from before to after the intervention (90% vs. 50%, p=0.05). However, the prevalence of uncontrolled hypertension did not significantly improve after the onsite intervention (38% vs. 28%, p=0

    Background Patient satisfaction is an important component of quality in healthcare delivery. To inform the expansion of Methadone Maintenance Treatment (MMT) services in Vietnam, we examined the satisfaction of patients with regards to different services delivery models and identified its associated factors. Methods We interviewed 1,016 MMT patients at 5 clinics in Hanoi and Nam Dinh province. The modified SATIS instrument, a 10-item scale, was used to measure three dimensions: “Services quality and convenience”, “Health workers’ capacity and responsiveness” and “Inter-professional care”. Results The average score was high across three SATIS dimensions. However, only one third of patients completely satisfied with general health services and treatment outcomes. Older age, higher education, having any problem in self-care and anxiety/depression were negatively associated with patient’s satisfaction. Meanwhile, patients receiving MMT at clinics, where more comprehensive HIV and general health care services were available, were more likely to report a complete satisfaction. Conclusion Patients were highly satisfied with MMT services in Vietnam. However, treatment for drug users should go beyond methadone maintenance to address complicated health demands of drug users. Integrating MMT with comprehensive HIV and general health services together with improving the capacity of health workers and efficiency of services organisation to provide interconnected health care for drug users are critical for improving the outcomes of the MMT program.

    This pilot study simultaneously evaluated the effects of various factors, including genetic variations of CYP2B6, CYP2C19, and ABCB1, demographic characteristics, disease states, methadone-drug interactions (MDIs), and poly-substance use, on the treatment responses among non-HIV patients in the methadone maintenance treatment program (MMTP) in Taiwan. A total of 178 patients were recruited from two major hospitals that provided MMTP services in southern Taiwan, and information regarding concomitant medications and diseases was acquired from the National Health Insurance (NHI) program. The results demonstrated that the methadone maintenance dose, CYP2B6 785G allele, and ABCB1 2677T allele have positive effects on the methadone plasma concentration. In contrast, patients with HCV coinfection, alcohol problems, and psychiatric diseases may have a negative response to treatment. Thus, a comprehensive evaluation of treatment responses in the MMTP should include not only genetic polymorphisms in methadone metabolism and transporter proteins, but also concomitant diseases, MDIs, and poly-substance use. The results also suggest that personalized medicine may be indispensable for a better outcome of the MMTP. PMID:24455721

    Out-of-pocket (OOP) payments may burden Methadone Maintenance Clinic patients. Since treatment is fully subsidized by the government, financial constraint might lead to patients being made to pay or be given incentive for inconvenience of therapy. This study thus evaluates the characteristic and commitment of methadone therapy patient's in terms of OOP cost, Willingness-To-Pay (WTP) and Willingness-To-Accept (WTA) concept. This survey utilizes the questionnaire by Boris ova & Goodman (2003) on the OOP, WTP and WTA. The forty adult patient's selected medical records from year 2009-2011 were from an urban government methadone clinic. Subject's selection was by convenient sampling based on the predetermined criteria. Most were male (95%) and Malay (60%) was the predominant group. Patients were group into three income groups; ≤ RM1000, ≥ RM1000 -≤ RM2000 and ≥ RM3000. The average OOP cost per month was RM391.30 (s.d RM337.50), which is about 35% of employed patient's monthly income. The wide variation could be attributed by high inter-individual and significant differences between patients in terms of transport, times taken to clinic, cost per trip and weekly household income (p=<0.05). Patients with income of less than RM1000 showed the highest tendency to pay for treatment, asked for the least money for inconvenience and many are unwilling to accept any payments. These findings showed that WTP and WTA is less of a concern for patients in the low-income group. To conclude, OOP payment is not a treatment barrier for most of the urban MMT patients.

    Contingency management (CM) for drug abstinence has been applied to individuals independently even when delivered in groups. We developed a group CM intervention in which the behavior of a single, randomly selected, anonymous individual determined reinforcement delivery for the entire group. We also compared contingencies placed only on cocaine abstinence (CA) versus one of four behaviors (CA, treatment attendance, group CM attendance, and methadone compliance) selected randomly at each drawing. Two groups were formed with 22 cocaine-dependent community-based methadone patients and exposed to both CA and multiple behavior (MB) conditions in a reversal design counterbalanced across groups for exposure order. The group CM intervention proved feasible and safe. The MB condition improved group CM meeting attendance relative to the CA condition. PMID:19192861

    The present study investigated whether psychological and/or physiological measures of stress would impede induction onto methadone maintenance and predict early (<6 months) discontinuation. Compared with controls, opioid-dependent subjects displayed increased distress on the perceived stress scale (PSS) and post-traumatic stress disorder checklist (PCLC); 60% exhibited abnormal cortisol. Addiction severity index (ASI), drug-use, and stress indices explained between 17–37% of the variance in engagement including attendance, opioid abstinence, and methadone stabilization. Participants who discontinued treatment displayed poor engagement, abnormal cortisol, elevated withdrawal symptoms, higher distress, and increased ongoing opioid use versus compliant individuals. Discontinuation was initially related to drug-use severity; however, by 6 months, retention depended primarily upon cortisol abnormalities, which increased an individual’s discontinuation risk by 7.7-fold. These findings support admission screening with the ASI/cortisol for drop out, and stress/drug-use indices for engagement that together may enable clinically-relevant early recognition and interventions for prevention of stress-induced relapse in opioid-dependent populations.

    Background We sought to assess injection practices, means of acquiring and disposing of syringes, and utilization and knowledge of harm reduction resources among injection drug users (IDUs) entering methadone maintenance treatment (MMT). Methods Interviews with 100 consecutive patients, including 35 IDUs, entering a MMT program in the Bronx, NY. Results Utilization of unsafe syringe sources was reported by 69% of IDUs in our sample. Most (80%) IDUs reused syringes, and syringe sharing was also common. Fewer than half knew that non-prescription pharmacy purchase of syringes was possible. The most common means of disposing of injecting equipment were the trash (63%) and syringe exchange programs (49%). Conclusions These findings indicate that drug users entering treatment under-utilize sanctioned venues to obtain sterile syringes or safely dispose of used injection equipment. Programs providing services to drug users should adopt a proactive stance to address the safety and health issues faced by injectors. PMID:16503997

    Using the DSM-IV criteria for personality disorders, prevalence rates for these disorders were evaluated among methadone maintenance patients, with a psychometric test--the Millon Clinical Multiaxial Inventory (MCMI-III). We found that 77% of patients met the study criteria for at least one personality disorder. Of those who had a personality disorder, 20% had two personality disorders, 14% had three personality disorders, and 6% had four personality disorders. Rates of specific personality disorders are reported. Consistencies and divergence from existing research literature are noted. It is suggested that future research compare psychometrically based self-report questionnaires to a structured clinical interview format, within the same clinical population. PMID:15540490

    Objective The aim of this study was to evaluate the risk factors associated with dropout from Methadone Maintenance Treatment (MMT) clinics within a 1 year follow-up cohort study in China. Methods A data analysis is to explore the adherence of MMT during one year from three hundred and twenty patients with heroin dependence at five clinics (3 in Shanghai, 2 in Kunming) in China. All participants were from the part of China-United States cooperation project entitled “Research about improving the compliance and efficacy of methadone maintenance treatment in China”. Our data analysis includes the patients’ attendance in the 6 months clinical study and the data in another 6 months afterward. The data of patients at baseline were collected with the Addiction Severity Index (ASI) which is a semi-structured questionnaire covering socio-demographic characteristics and drug use history. The one year attendance after recruitment at the clinics and daily dose were abstracted from the MMT clinic register system. The Cox proportional hazards model were used to explore the risk factor of dropout, defined as seven consecutive days without methadone. Results By the end of 1 year of treatment 86 patients still remained in MMT without dropout (87% in Shanghai and 13% patients in Kunming). Over the entire 1-year period the median days of remaining in the program were 84 days (in Shanghai and Kunming were 317 days and 22 days).The factors associated with retention included age (HR = 0.98, 95%C.I.:0.96-0.99, P = 0.0062) and ASI alcohol scores (HR = 5.72, 95%C.I.:1.49-21.92, P = 0.0109) at baseline. Conclusion One year retention of newly recruited patients with heroin dependence was related to age and ASI alcohol scores at baseline. The adherence is poorer for the patients who are young and having more serious alcohol problems. PMID:24565169

    Methadone maintenance treatment (MMT) is commonly used for controlling opioid dependence, preventing withdrawal symptoms, and improving the quality of life of heroin-dependent patients. A steady-state plasma concentration of methadone enantiomers, a measure of methadone metabolism, is an index of treatment response and efficacy of MMT. Although the methadone metabolism pathway has been partially revealed, no genome-wide pharmacogenomic study has been performed to identify genetic determinants and characterize genetic mechanisms for the plasma concentrations of methadone R- and S-enantiomers. This study was the first genome-wide pharmacogenomic study to identify genes associated with the plasma concentrations of methadone R- and S-enantiomers and their respective metabolites in a methadone maintenance cohort. After data quality control was ensured, a dataset of 344 heroin-dependent patients in the Han Chinese population of Taiwan who underwent MMT was analyzed. Genome-wide single-locus and haplotype-based association tests were performed to analyze four quantitative traits: the plasma concentrations of methadone R- and S-enantiomers and their respective metabolites. A significant single nucleotide polymorphism (SNP), rs17180299 (raw p = 2.24 × 10−8), was identified, accounting for 9.541% of the variation in the plasma concentration of the methadone R-enantiomer. In addition, 17 haplotypes were identified on SPON1, GSG1L, and CYP450 genes associated with the plasma concentration of methadone S-enantiomer. These haplotypes accounted for approximately one-fourth of the variation of the overall S-methadone plasma concentration. The association between the S-methadone plasma concentration and CYP2B6, SPON1, and GSG1L were replicated in another independent study. A gene expression experiment revealed that CYP2B6, SPON1, and GSG1L can be activated concomitantly through a constitutive androstane receptor (CAR) activation pathway.

    Objectives: Our objective was to determine the impact that a patient's geographic status has on the efficacy of first-time methadone maintenance therapy (MMT) retention. Methods: We conducted an observational cohort study using administrative health care databases for patients who commenced methadone therapy between 2003 and 2012. Patients were stratified on the basis of their location of residence into 1 of 4 groups—Southern Urban, Southern Rural, Northern Urban, or Northern Rural. The primary outcome was continuous retention in treatment, defined as 1 year of uninterrupted therapy on the basis of prescription refill data. Mortality was measured as a secondary outcome. Results: We identified 17,211 patients initiating first-time MMT during this 10-year period. Nearly half of patients initiating therapy in northern regions completed 1 year of treatment (48.9%; N = 258 and 47.0%; N = 761 in Northern Rural and Urban regions, respectively), whereas lower rates of 40.6% (N = 410) and 39.3% (N = 5,518) occurred in Southern Rural and Urban regions, respectively. Patients residing in Northern Rural and Northern Urban regions were 31% (adjusted odds ratio = 1.31; 95% confidence interval [CI], 1.09%–1.58%] and 14% (adjusted odds ratio = 1.14; 95% CI, 1.02%–1.27%] more likely to be retained in treatment compared with those residing in Southern Urban regions. There was no significant difference in treatment retention between those residing in Southern Rural and Southern Urban regions. A mortality rate of 3% was observed within 1 year of patients initiating treatment, with patients in the Southern Rural region having the highest rate (4.85%). Conclusions: Our study identified regional differences in retention rates and mortality of first-time MMT. These findings may relate to geographic isolation and limited methadone program availability experienced in northern regions. We interpret the data to suggest that patients who have reduced access to

    Background In opiate-dependent individuals, abstinence results in deficits in cognitive functioning, which may be exacerbated by medication-associated sleep disruption. Method To assess cognitive function and the influence of sleep deprivation (SD), 14 healthy control (HC) and 22 methadone maintained (MM) participants completed the Continuous Performance Task (CPT) after a baseline night, a night of total SD, and two recovery sleep nights. The Digit Symbol Substitution Task (DSST) was administered at bedtime and in the morning. Secondary analyses separated MM participants into short- (<12 months; n=8) and long-term (≥12 months; n=14) treatment duration groups, and into low- (< 80 mg; n=9) and high-dose (≥ 80 mg; n=13) groups. Results Linear mixed model ANOVAs revealed that there was no effect of SD. Across all days MM participants had more errors of omission, fewer correct responses, and slower reaction times (RTs) on the CPT, and fewer accurate substitutions on the evening and morning DSST. Short-term MM participants exhibited slower RTs on the CPT, and fewer correct substitutions on the evening DSST compared to long-term MM participants. Low-dose MM participants had slower RTs on the CPT than HCs and high-dose MM participants. Conclusion These data demonstrate that methadone-maintained individuals exhibit poorer performance on tasks of psychomotor speed and selective attention/impulsivity, but with longer-term treatment, performance appears to return toward control levels. Furthermore, while one day of SD was enough to alter subjective reports of sleep quality, cognitive function may be more resilient. PMID:22552256

    Methadone maintenance therapy is an effective treatment for opiate dependence, but more than three-quarters of persons receiving the treatment report sleep quality disturbances. In this double-blind, randomized, controlled trial, we recruited 90 individuals receiving methadone for at least one month who reported sleep disturbances and had Pittsburgh Sleep Quality Index (PSQI) scores > 5. The purpose of this study was to determine whether Suan Zao Ren Tang, one of the most commonly prescribed traditional Chinese medications for treatment of insomnia, improves subjective sleep among methadone-maintained persons with disturbed sleep quality. Ninety patients were randomly assigned to intervention group (n = 45) and placebo group (n = 45), and all participants were analyzed. Compared with placebo treatment, Suan Zao Ren Tang treatment for four weeks produced a statistically significant improvement in the mean total PSQI scores (P = 0.007) and average sleep efficiency (P = 0.017). All adverse events (e.g., lethargy, diarrhea, and dizziness) were mild in severity. Suan Zao Ren Tang is effective for improving sleep quality and sleep efficiency among methadone-maintained patients with sleep complaints. PMID:26346534

    We conducted a survey to determine the rate of adherence to and factors associated with compliance with a methadone maintenance treatment program (MMTP) among injecting drug users in Nepal. We conducted face-to-face structured interviews with 165 methadone treatment patients aged 20-54 years during 5-20 April 2015. Data analysis included percentages, means, standard deviations, chi-square tests and multiple logistic regression analysis. Seventy-two point one percent of respondents had good adherence to a MMTP. Multiple logistic regression with 81.8% prediction showed respondents without a previous history of relapse were 2.7 times more likely to adhere to the MMTP than those with a history of relapse [Adjusted OR = 2.772; 95% Confidence interval (CI): 1.163-6.605]. Respondents with a good knowledge of the MMTP 9.4 times more likely to be adherent to the MMTP than those with a poor to fair knowledge of the MMTP (Adjusted OR = 9.464; 95% CI: 3.873-23.126). The likelihood of MMTP adherence was 4.5 times more likely when methadone treatment services were available than those where the availability of methadone treatment services were low to moderate (Adjusted OR = 4.553; 95% CI: 1.883-11.008). Knowledge and availability of MMTP need to be improved in the study area in Nepal. PMID:27244967

    Injection drug users (IDUs) are at high risk of acquiring HIV infection through preventable drug- and sex-related HIV risk behaviors. In recent decade, there has been a growing evidence that methadone maintenance treatment (MMT) is associated with a significant decrease in both drug- and sex-related risk behaviors among this high-risk population. The better understanding of the relationship between MMT and HIV-related risk behaviors will help to better inform future HIV prevention strategies, which may have policy implications as well. In this systematic review, we therefore aimed to explore the relevant literature to more clearly examine the possible impact of MMT on HIV risks behaviors among high-risk IDUs. The findings thus far suggest that MMT is associated with a significant decrease in injecting drug use and sharing of injecting equipment. Evidence on sex-related risk behavior is limited, but suggest that MMT is associated with a lower incidence of multiple sex partners and unprotected sex. The literature also suggests that the most significant factor in reducing HIV risks was treatment adherence. As such, more attention needs to be given in future studies to ensure the higher rates of access to MMT as well as to improve the adherence to MMT. PMID:27066590

    The efficacy and effectiveness of methadone maintenance treatment (MMT) in the medical management of opioid addiction has been well-established, but treatment outcomes are compromised by the continued use of licit and illicit drugs during MMT. The present study examined the relationship between in-treatment illicit drug use and retention and dropout of 604 MMT patients in Washington, D.C. Sixty-eight percent of patients did not test positive for an unprescribed drug during the study period. Of patients who tested positive for an illicit drug during the baseline period, 55% tested positive for cocaine, 44% for opiates, 23% for THC, 20% for benzodiazepines, 7% for PCP, and 4% for amphetamines. Those testing positive were three times more likely to leave treatment than those who did not test positive. Testing positive for one drug doubled the rate of attrition; testing positive for multiple drugs quadrupled the risk of attrition. Non-prescribed opioid or benzodiazepine use was a predictor of MMT dropout, but prescribed opioid or benzodiazepine use was not. Continued illicit drug use poses significant risk for subsequent premature termination of MMT. Assertive clinical management of continued illicit drug use could provide mechanisms to enhance MMT retention and long-term recovery outcomes. PMID:25052787

    Background Opiates are the main drugs of abuse, and Methadone Maintenance Treatment (MMT) is the most widely administered drug addiction treatment program in Iran. Our study aimed to investigate patterns of pre-treatment drug abuse, addiction treatment history and characteristics of patients in MMT in Tehran. Methods We applied a stratified cluster random sampling technique and conducted a cross-sectional survey utilizing a standard patient characteristic and addiction history form with patients (n = 810) in MMT. The Chi-square test and t-test served for statistical analyses. Results A clear majority of the participants were men (96%), more than 60% of whom were between 25 and 44 years of age, educated (89% had more than elementary education), and employed (>70%). The most commonly reported main drugs of abuse prior to MMT entry were opium (69%) and crystalline heroin (24%). The patients’ lifetime drug experience included opium (92%), crystalline heroin (28%), cannabis (16%), amphetamines (15%), and other drugs (33%). Crystalline heroin abusers were younger than opium users, had begun abusing drugs earlier, and reported a shorter history of opiate addiction. Conclusion Opium and crystalline heroin were the main drugs of abuse. A high rate of addiction using more dangerous opiate drugs such as crystalline heroin calls for more preventive efforts, especially among young men. PMID:22676557

    Accumulating findings suggest a relationship between partner violence and HIV risk among women, however, this issue has yet to be adequately researched among men. This study examines the relationship between perpetrating intimate partner violence and HIV risk behavior among a sample of men in methadone maintenance treatment programs (MMTPs). Data were collected on 273 sexually active men, who were recruited from four inner-city MMTP clinics. More than a third of the sample reported perpetrating intimate physical abuse and 15% reported severe physical abuse in the past 12 months. Results from multiple logistic regression analyses indicate that after adjusting for demographic, poverty, and drug-use factors, men who abused an intimate partner were almost 4 times more likely to have more than one intimate partner, almost 3 times more likely to have unprotected anal sex, and 2.6 times more likely to have sex with a drug-injecting sexual partner than their counterparts. This study showed that men who perpetrated partner violence were at higher risk for HIV transmission. HIV prevention interventions need to consider the complex relationship between partner violence and HIV risk. PMID:11547622

    While methadone maintenance treatment (MMT) is beneficial for heroin dependence, there is little information regarding the reductions in monetary cost and gains in productivity following MMT. The aim of this study was to evaluate the changes in the monetary cost of heroin addiction and productivity after one year of MMT. Twenty-nine participants from an MMT clinic were included. The monetary cost, productivity, quality of life (QOL) and mental health status were assessed at both baseline and one year follow-up. The average annual total cost was approximately US$26,485 (1.43 GDP per capita in 2010) at baseline, and decreased by 59.3% to US$10,784 (0.58 GDP) at follow-up. The mean number of months of unemployment dropped from 6.03 to 2.79, the mean income increased to exceed the basic salary, but only reached 45.3% of the national average monthly earnings. The participants׳ mental health improved, but their QOL scores did not increase significantly. After one year of MMT, the monetary cost of heroin addiction fell, both the productivity and mental health of the participants׳ improved, but limited gains were seen with regard to their QOL.

    Working memory is impaired in opioid-dependent individuals, yet the neural underpinnings of working memory in this population are largely unknown. Previous studies in healthy adults have demonstrated that working memory is supported by a network of brain regions that includes a cerebro-cerebellar circuit. The cerebellum, in particular, may be important for inner speech mechanisms that assist verbal working memory. This study used functional magnetic resonance imaging (fMRI) to examine brain activity associated with working memory in 5 opioid-dependent, methadone-maintained patients and 5 matched, healthy controls. An item recognition task was administered in two conditions: 1) a low working memory load “match” condition in which participants determined whether target letters presented at the beginning of the trial matched a probe item, and 2) a high working memory load “manipulation” condition in which participants counted two alphabetical letters forward of each of the targets and determined whether either of these new items matched a probe item. Response times and accuracy scores were not significantly different between the groups. FMRI analyses indicated that, in association with higher working memory load (“manipulation” condition), the patient group exhibited hyperactivity in the superior and inferior cerebellum and amygdala relative to that of controls. At a more liberal statistical threshold, patients exhibited hypoactivity in the left prefrontal and medial frontal/pre-SMA regions. These results indicate that verbal working memory in opioid-dependent individuals involves a disrupted cerebro-cerebellar circuit, and shed light on the neuroanatomical basis of working memory impairments in this population.

    2011-01-01

    Background Ongoing psychiatric symptoms and substance use are common difficulties experienced by clients enrolled in methadone maintenance treatment (MMT). However, little research to date has evaluated if specific types of current substance use are related to specific types of current psychiatric symptoms. The present study investigated these relationships with a sample of clients enrolled in a low-threshold MMT program (i.e., clients are not expelled if they continue to use substances). Some clients enrolled in low-threshold programs may never achieve complete abstinence from all substances. Thus, understanding the possibly perpetuating relationships between concurrent substance use and psychiatric symptoms is important. Understanding such relationships may aid in developing possible target areas of treatment to reduce substance use and/or related harms in this population. Methods Seventy-seven individuals were interviewed regarding methadone usage and current and past substance use. Current psychiatric symptoms were assessed using a modified version of the Psychiatric Diagnostic Screening Questionnaire (PDSQ). Relationships between types of substances used in the past 30 days and the types and number of psychiatric symptoms experienced in the same timeframe were examined. Results The majority of participants (87.0%) reported using alcohol, illicit substances, non-prescribed prescription opioids, or non-prescribed benzodiazepines in the past 30 days and 77.9% of participants reported currently experiencing psychiatric symptoms at levels that would likely warrant diagnosis. Current non-prescribed benzodiazepine use was a predictor for increased severity (i.e., symptom count) of almost all anxiety and mood disorders assessed. Conversely, number and presence of generalized anxiety symptoms and presence of social phobia symptoms predicted current non-prescribed benzodiazepine and alcohol use, respectively. Conclusions Individuals enrolled in the present low

    Today's methadone patients differ greatly from those of the past. Because of the rise of polydrug use and the HIV and hepatitis epidemics, treatment has become much more complex, which multiply the concerns and complexities of treatment. Patients entering methadone programs are also more commonly presenting at ages well into their 50s, 60s, and 70s; and this phenomenon of high rates continues to grow. The majority of these individuals in treatment have presented with a number of significant comorbid medical conditions that will progress and eventually lead to death. This aging cohort must be approached with a modified treatment plan that focuses on management and promoting healthy aging, while attending to their maximum delay of illness, disease, and disability. This article argues that it is necessary for counselors working with this group to adopt a palliative care philosophy. This article also makes recommendations in areas that counselors need to be knowledgeable and skilled in to provide appropriate palliative services specific to this aging population with multiple needs as they near end of life.

  5. Categorising methadone: Addiction and analgesia.

    Keane, Helen

    2013-11-01

    While methadone was first developed as an analgesic, and used for this purpose before it was adopted as a therapy for drug dependence, it is this latter use which has saturated its identity. Most of the literature and commentary on methadone discusses it in the context of methadone maintenance therapy (MMT). But one of the effects of the liberalization of opiate prescription for chronic pain which took place in the 1990s was the re-emergence of methadone as a painkiller. This article examines the relationship between methadone the painkiller and methadone the addiction treatment as it is constituted in recent medical research literature and treatment guidelines. It highlights the way medical discourse separates methadone into two substances with different effects depending on the problem that is being treated. Central to this separation is the classification of patients into addicts and non-addicts; and pain sufferers and non-pain sufferers. The article argues that despite this work of making and maintaining distinctions, the similarities in the way methadone is used and acts in these different medical contexts complicates these categories. The difficulties of keeping the 'two methadones' separate becomes most apparent in cases of MMT patients also being treated for chronic pain. PMID:23768774

    Aims Methadone maintenance treatment (MMT) is widely available in China; but, high rates of illicit opiate use and dropout are problematic. The aim of this study was to test whether cognitive behavioral therapy (CBT) in conjunction with MMT can improve treatment retention and reduce opiate use. Method A total of 240 opiate-dependent patients in community-based MMT clinics were randomly assigned to either weekly CBT plus standard MMT (CBT group, n=120) or standard MMT (control group, n=120) for 26 weeks. The primary outcomes were treatment retention and opiate-negative urine test results at 12 weeks and 26 weeks. The secondary outcomes were composite scores on the Addiction Severity Index (ASI) and total scores on the Perceived Stress Scale (PSS) at 12 weeks and 26 weeks. Results Compared to the control group in standard MMT, the CBT group had higher proportion of opiate-negative urine tests at both 12 weeks (59% vs. 69%, p<0.05) and 26 weeks (63% vs. 73%, p<0.05); however, the retention rates at 12 weeks (73.3% vs. 74.2%, p=0.88) and 26 weeks were not different (55.8% vs. 64.2%, p=0.19) between the two groups. At both 12 and 26 weeks, all of the ASI component scores and PSS total scores in the CBT group and control group decreased from baseline; but the CBT group exhibited more decreases in ASI employment scores at week 26 and more decrease in the PSS total score at week 12 and week 26. Conclusions CBT counselling is effective in reducing opiate use and improving employment function and in decreasing stress level for opiate-dependent patients in MMT in China.

    Background: The increase in high-risk injections and unsafe sexual behaviors has led to increased HIV infection prevalence among Intravenous Drug Users (IDUs). The high costs of HIV/AIDS care and low financial resources necessitate an economic evaluation to make the best decision for the control of HIV/AIDS. Objectives: This study was conducted to determine the cost-effectiveness of Methadone Maintenance Treatment (MMT) centers in HIV infection prevention among drug users. Materials and Methods: In this interventional study, we included all the seven MMT centers and the drug users registered there (n = 694). We calculated all the costs imposed on the government, i.e. Provider of case. Mathematical models were used to estimate the number of HIV cases averted from high-risk behaviors. Sensitivity analyses were performed to show the effects of uncertainty in parameters on the number of HIV cases averted and also Incremental Cost-Effectiveness Ratio (ICER). Results: Based on the averted models, the selected MMT centers could prevent 128 HIV cases during 1 year. The total cost was $ 547423 and that of HIV/AIDS care in the no intervention scenario was estimated $ 14171816. ICER was $ 106382 per HIV case averted. The results of the sensitivity analysis indicated that MMT intervention was cost-effective even in the worst scenario and ICER varied from $ 39149 to $ 290004 per HIV case averted. Conclusions: With regard to the high prevalence of drug injection among drug users and considering the high effectiveness and cost-effectiveness of MMT centers in preventing HIV infection, establishment of MMT centers in regional and national levels seems reasonable.

    Background Methadone maintenance treatment (MMT) reduces HIV risk behaviors and improves access to HIV-related services among drug users. In this study, we assessed the uptake and willingness of MMT patients to refer HIV testing and counseling (HTC) service to their sexual partners and relatives. Methods Health status, HIV-related risk behaviors, and HTC uptake and referrals of 1,016 MMT patients in Hanoi and Nam Dinh were investigated. Willingness to pay (WTP) for HTC was elicited using a contingent valuation technique. Interval and logistic regression models were employed to determine associated factors. Results Most of the patients (94.2%) had received HTC, 6.6 times on average. The proportion of respondents willing to refer their partners, their relatives and to be voluntary peer educators was 45.7%, 35.3%, and 33.3%, respectively. Attending MMT integrated with HTC was a facilitative factor for HTC uptake, greater WTP, and volunteering as peer educators. Older age, higher education and income, and HIV positive status were positively related to willingness to refer partners or relatives, while having health problems (mobility, usual care, pain/discomfort) was associated with lower likelihood of referring others or being a volunteer. Over 90% patients were willing to pay an average of US $17.9 for HTC service. Conclusion The results highlighted the potential role of MMT patients as referrers to HTC and voluntary peer educators. Integrating HIV testing with MMT services and applying users’ fee are potential strategies to mobilize resources and encourage HIV testing among MMT patients and their partners. PMID:27046029

    Aims In 2009, Mexico passed legislation to decriminalize drug possession and improve access to addiction treatment. We undertook research to assess the implementation of the reform among a cohort of people who inject drugs (PWID) in Tijuana. This study specifically sought to determine whether discretionary policing practices like extortion impact access to methadone maintenance therapy (MMT) in Tijuana, a city characterized by high levels of drug-related harms. Methods Generalized estimating equation analyses were used to construct longitudinal confounding models to determine the association between paying a police bribe and MMT enrolment among PWID in Tijuana enrolled in a prospective cohort study. Outcome of interest was MMT enrolment in the past six months. Data on police interactions and MMT enrolment were also obtained. Results Between October, 2011 and September, 2013, 637 participants provided 1,825 observations, with 143 (7.8%) reports of MMT enrolment during the study period. In a final confounding model, recently reporting being forced to pay a bribe to police was significantly associated with an increased likelihood of accessing MMT (Adjusted Odds Ratio = 1.69, 95% Confidence Interval: 1.02 – 2.81, p = 0.043). However, in 56 (39.2%) cases, MMT enrolment ceased within six months. The majority of participant responses cited the fact that MMT was too expensive (69.1%). Discussion Levels of MMT access were low. PWID who experienced police extortion were more likely to access MMT at baseline, though this association decreased during the study period. Coupled with the costs of MMT, this may compromise MMT retention among PWID. PMID:25655577

    Background Hepatitis C virus (HCV) is the most common viral infection among injecting drug users worldwide. We aimed to assess HCV antibody prevalence and associated risk factors among clients in the Chinese national methadone maintenance treatment (MMT) program. Methods Data from 296,209 clients who enrolled in the national MMT program between March 2004 and December 2012 were analyzed to assess HCV antibody prevalence, associated risk factors, and geographical distribution. Results Anti-HCV screening was positive for 54.6% of clients upon MMT entry between 2004 and 2012. HCV antibody prevalence at entry declined from 66.8% in 2005 to 45.9% in 2012. The most significant predictors of HCV seropositivity were injecting drug use (adjusted odds ratio [AOR]: 8.34, 95% confidence interval [CI]: 8.17–8.52, p<0.0001) and a history of drug use ≥9 years (AOR: 2.01, 95% CI: 1.96–2.06, p<0.0001). Being female, of Uyghur or Zhuang ethnicity, and unmarried were identified as demographic risk factors (all p-values<0.0001). Of the 28 provincial-level divisions included in the study, we found that 5 divisions had HCV antibody prevalence above 70% and 20 divisions above 50%. The HCV screening rate within 6 months after MMT entry greatly increased from 30.4% in 2004 to 93.1% in 2012. Conclusions The current HCV antibody prevalence remains alarmingly high among MMT clients throughout most provincial-level divisions in China, particularly among injecting drug users and females. A comprehensive prevention strategy is needed to control the HCV epidemic among MMT clients in China. PMID:26906025

    Despite the recent explosion of behavioral health interventions delivered on mobile devices, little is known about factors that make such applications practical, engaging and useful to their target audience. This study reports on the feasibility, acceptability and preliminary efficacy of a prototype of a novel, interactive mobile psychosocial intervention to reduce problematic drug use among clients in methadone maintenance treatment (MMT). A mixed-methods pilot study with new MMT clients (n=25) indicated that the mobile intervention approach was feasible, and that participants found the intervention highly acceptable and useful. On 100-point visual analog scale (VAS) items, participants reported high levels of liking the program (M=75.6), and endorsed it as useful (M=77.5), easy to use (M=80.7), and containing a significant amount of new information (M=74.8). When compared with 25 study participants who received standard MMT alone, pilot participants rated their treatment significantly higher in interestingness and usefulness, and were significantly more satisfied with their treatment. In qualitative interviews, participants reported using the mobile intervention in a range of settings, including during times of heightened risk for substance use, and finding it helpful in managing drug cravings. Additionally, pilot participants showed evidence of increased treatment retention and abstinence from illicit opioids (in terms of effect size) over a 3-month period relative to those in standard MMT, suggesting the application’s potential to enhance treatment outcomes. These promising findings suggest that an evidence-based mobile therapeutic tool addressing substance use may appeal to drug treatment clients and have clinical utility as an adjunct to formal treatment.

    Background: To evaluate the effectiveness of a relapse prevention cognitive-behavioral model, based on Marlatt treatment approach, in Opioid-dependent patients participating in the Methadone Maintenance Treatment (MMT) in Iran. Methods: The study consisted of 92 individuals treated with methadone in Iranian National Center of Addiction Studies (INCAS). Participants were randomized into two groups: educational intervention group (N=46) and control group (N=46). The intervention was comprised of 10 weekly 90 minute sessions, done during a period of 2.5 months based on the most high risk situations determined using Inventory Drug Taking Situation instrument. Relapse was defined as not showing up for MMT, drug use for at least 5 continuous days, and a positive urinary morphine test. Results: While, only 36.4% of the intervention group relapsed into drug use, 63.6% of the control group relapsed. The result of the logistic regressions showed that the odd ratio of the variable of intervention program for the entire follow up period was 0.43 (P<0.01). Further, the odd ratio of this variable in one month, three months, and 195 days after the therapy were 0.48 (P<.03), 0.31 (P<.02), and 0.13 (P<.02) respectively that revealed that on average, the probability of relapse among individuals in the intervention group was lower than patients in control group Conclusion: Relapse prevention model based on Marlatt treatment approach has an effective role in decreasing relapse rate. This model can be introduced as a complementary therapy in patients treated with methadone maintenance. PMID:26056645

    The purpose of this study was to investigate the effects of methadone treatment and buprenorphine treatment on retention in treatment, urine drug testing results, psychiatric status, social adjustment, and quality of life among patients involved in long-term treatment with the cited medications. Two hundred thirteen patients (106 on buprenorphine treatment and 107 on methadone treatment) were enrolled in this open study at the 3rd month of their treatment and followed up until the 12th month; those who left the program before the end of the 3rd month of their treatment were not included in the study sample. The results of this study show statistically significant improvements in opioid use, psychiatric status, and quality of life between the 3rd and 12th months for both medications. This study suggests the long-term efficacy of methadone treatment and buprenorphine treatment on symptoms of opioid addiction and quality of life. PMID:17588494

    Fifty-five former opioid addicts who have been methadone maintained patients for 10 or more years and whose urine has tested negative for drugs for 2 or more years were compared to 99 former opioid addicts who have been medication-free for 10 or more years. Groups were comparable in age and education, but the medication-free subjects were younger when having started opioids with more severe addiction scores. Methadone maintained patients presented with a higher proportion of psychiatric comorbidity and chronic pain. Their scores of perceived sleep quality and cognitive state were poorer than the medication-free individuals. Possible explanations of the differences are discussed in this article. PMID:26284418

    Background Methadone maintenance patients (MMP) often abuse other drugs, including alcohol. The combined use of methadone and alcohol could impair performance and daily functioning. Objective To examine the effects of methadone in combination with alcohol, as well as acute increases in methadone, on performance outcomes. Method This double blind, double-dummy, crossover study included 8 opioid dependent participants stabilized on methadone. Participants completed 6 inpatient sessions corresponding to methadone (100% or 150% of daily dose) and beverage (placebo, 0.25 or 0.50 g/kg alcohol). Performance tasks were completed before and after drug administration. Area under the timecourse values were analyzed by a 2 (methadone dose) by 3 (alcohol dose) repeated measures analysis of variance. Results Main effects of methadone were observed for two attention outcomes, suggesting reduced accuracy and slowed responding at an elevated methadone dose. In addition, main effects of alcohol were observed for episodic memory (false alarms and response bias) suggesting more impulsive responding as alcohol dose increased. No robust interactions of methadone and alcohol were observed for any outcome. Conclusions Study findings indicate that an acute increase in methadone (150%) and a moderate dose of alcohol (2–3 drinks) can impair distinct aspects of performance, although no significant interactive effect between methadone and alcohol was found. Future studies with larger sample sizes, larger doses, and more clinically informative tasks could expand on the present findings and further explore the cognitive consequences of concurrent opioid and alcohol use.

    Objective. To report the one-year retention rate and the prevalence of illicit opioid use and cocaine use in the Low-Threshold/High-Tolerance (LTHT) methadone maintenance treatment (MMT) clinic located in Saint John, New Brunswick, Canada. Methods. A description of the LTHT MMT clinic is provided. The one-year retention rate was determined by collecting data on patients who enrolled in the LTHT MMT clinic between August 04, 2009 and August 04, 2010. The prevalence of illicit drug use was determined using a randomly selected retrospective cohort of 84 participants. For each participant the results of six consecutive urine tests for the most recent three months were compared to the results of the first six consecutive urine tests after program entry. Results. The one-year retention rate was 95%, 67% of the cohort achieved abstinence from illicit opioids and an additional 13% abstained from cocaine use. Conclusion. The novel feature of the LTHT MMT clinic is that patients are not denied methadone because of lack of ancillary services. Traditional comprehensive MMT programs invest the majority of financial resources in ancillary services that support the biopsychosocial model, whereas the LTHT approach utilizes a medical model and directs resources at medical management.

    To determine the effect of sexual abuse history on chronic pain and its relation to opioid addiction and methadone maintenance treatment (MMT), we studied current women MMT patients, and women patients from a sexual abuse treatment center with no history of opioid addiction. Questionnaires included Chronic Pain, Chronic Severe Pain, the Yale-Brown Obsessive Compulsive Scale, the Dissociative Experiences Scale (DES), and the Structured Interview for Disorders of Extreme Stress (complex-PTSD). Chronic severe pain was most prevalent among sexually abused women with no history of opioid addiction (64% of 25), followed by sexually abused MMT women (30.9% of 68), and MMT women with no history of sexual abuse (25% of 8, p = 0.01). Pain severity correlated with dissociation and complex-PTSD scores. The sexually abused non-MMT women had higher rates of high dissociation scores (DES ≥ 30) and complex-PTSD, but fewer obsessive-compulsive disorder symptoms (scored ≥16) than the MMT sexually abused women. Chronic pain was found to be highly prevalent among sexually abused women, independent of being methadone-maintained with an addiction history. The high known prevalence of chronic pain among MMT patients, which may be attributable to opioid-induced hyperalgesia, may partially reflect the sexual abuse history, and should be targeted in future studies evaluating pain indices.

    There is a paucity of data to aid in assessing whether postmortem methadone findings in breastfed infants are clinically and/or toxicologically significant. Two cases are reported in which methadone was detected in deceased neonates whose mothers were enrolled in methadone maintenance programs and were breastfeeding. In addition to a complete autopsy and toxicological testing for alcohol, prescription medications, and drugs of abuse, pharmacogenetic analysis was performed for variants in genes related to methadone metabolism and response. In both cases, the postmortem methadone concentration measured in neonatal heart blood was higher than the maximum serum methadone concentration reported in living breastfed infants whose mothers were receiving methadone. However, additional analysis of antemortem blood indicated postmortem redistribution of methadone. Pharmacogenetic results were suggestive of a potential predisposition to methadone toxicity based on studies in adults; the significance of these findings in breastfed neonates requires further research. The medical cause of death was unascertained in both cases. PMID:26513313

  1. Harm reduction, methadone maintenance treatment and the root causes of health and social inequities: An intersectional lens in the Canadian context

    PubMed Central

    2011-01-01

    Background Using our research findings, we explore Harm Reduction and Methadone Maintenance Treatment (MMT) using an intersectional lens to provide a more complex understanding of Harm Reduction and MMT, particularly how Harm Reduction and MMT are experienced differently by people dependent on how they are positioned. Using the lens of intersectionality, we refine the notion of Harm Reduction by specifying the conditions in which both harm and benefit arise and how experiences of harm are continuous with wider experiences of domination and oppression; Methods A qualitative design that uses ethnographic methods of in-depth individual and focus group interviews and naturalistic observation was conducted in a large city in Canada. Participants included Aboriginal clients accessing mainstream mental health and addictions care and primary health care settings and healthcare providers; Results All client-participants had profound histories of abuse and violence, most often connected to the legacy of colonialism (e.g., residential schooling) and ongoing colonial practices (e.g., stigma & everyday racism). Participants lived with co-occurring illness (e.g., HIV/AIDS, Hepatitis C, PTSD, depression, diabetes and substance use) and most lived in poverty. Many participants expressed mistrust with the healthcare system due to everyday experiences both within and outside the system that further marginalize them. In this paper, we focus on three intersecting issues that impact access to MMT: stigma and prejudice, social and structural constraints influencing enactment of peoples' agency, and homelessness; Conclusions Harm reduction must move beyond a narrow concern with the harms directly related to drugs and drug use practices to address the harms associated with the determinants of drug use and drug and health policy. An intersectional lens elucidates the need for harm reduction approaches that reflect an understanding of and commitment to addressing the historical, socio

    Objective Client adherence is vital for effective methadone maintenance treatment (MMT). This study explores the pattern and associated factors of client adherence, drop-out and re-enrolment in the Chinese MMT programme over the period of 2006–2013. Methods This retrospective study was conducted in 14 MMT clinics in Guangdong Province, China. We employed Kaplan-Meier survival analysis to estimate the rates of drop-out and re-enrolment of MMT clients and multivariate Cox regression to identify associated factors. Results Among 1,512 study participants, 79% have experienced ‘drop-out’ during the 7-year study period. However, 82% ‘dropped-out’ clients resumed treatment at a later time. Low education level (junior high or below versus otherwise, HR = 1.21, 1.05–1.40), low methadone dosage in the first treatment episode (<50 ml versus ≥50 ml, HR = 1.84, 1.64–2.06) and higher proportion of positive urine test (≥50% versus<50%, HR = 3.72, 3.30–4.20) during the first treatment episode were strong predictors of subsequent drop-outs of the participants. Among the ‘dropped-out’ clients, being female (HR = 1.40, 1.23–1.60), being married (HR = 1.19, 1.09–1.30), and having a higher proportion of positive urine tests in the first treatment episode (≥50% versus<50%, HR = 1.35, 1.20–1.51) had greater likelihood of subsequent re-enrolment in MMT. Clients receiving lower methadone dosage (first treatment episode <50 ml versus ≥50 ml, HR = 1.12, 1.03–1.23; the last intake before drop-out <50 ml versus ≥50 ml, HR = 1.16, 1.04–1.30) were also more likely to re-enrol. Conclusion Persistent cycling in-and-out of clients in MMT programmes is common. Insufficient dosage and higher proportion of positive urine samples in the first treatment episode are the key determinants for subsequent client drop-out and re-enrolment. Interventions should target clients in their early stage of treatment to improve retention in the long term. PMID:26484772

    Background: Due to the chronic and recurrent nature of addiction, many people who quit drug addiction may slip back into the pattern of using drugs shortly after the detoxification period. Emotion-regulation strategies and resilience play an important role in preventing the recurrences of substance abuse. Objectives: This study aimed to compare the effects of methadone-maintenance therapy (MMT) and interactive therapy (a combination of MMT and cognitive-behavioral therapy) on improving emotion-regulation strategies and resilience among opiate-dependent clients. Patients and Methods: This pretest-posttest quasi-experimental study was performed on 60 patients with substance abuse admitted to Methadone Addiction Treatment Centers and Detox Centers in Sari within three months of therapy for their addiction (from October to December 2013). Then, the participants were randomly assigned to two different groups (n = 30) were examined in two groups of 30 people targeted to be available in the selected population. Participants in all three groups, before and after the intervention, filled out the questionnaires of Schutte emotional intelligence scale and Connor-Davidson resiliency questionnaire. Data were analyzed using the analysis of covariance method. Results: The results showed that an interactive therapy would be significantly more effective than the MMT on improving emotion-regulation strategies and promoting the resilience level among opiate-dependent clients. Moreover, the results showed that cognitive- behavior therapy combined with MMT may improve emotion-regulation strategies, and promote the amount of resiliency and recovery. Conclusions: The cognitive-behavior therapy combined with MMT can improve emotion-regulation strategies and resiliency and thus prevent the substance-abuse relapse. PMID:25821751

  5. Optimum Methadone Compliance Testing

    PubMed Central

    2006-01-01

    Executive Summary Objective The objective of this analysis was to determine the diagnostic utility of oral fluid testing collected with the Intercept oral fluid collection device. Clinical Need: Target Population and Condition Opioids (opiates or narcotics) are a class of drugs derived from the opium poppy plant that typically relieve pain and produce a euphoric feeling. Methadone is a long-acting synthetic opioid used to treat opioid dependence and chronic pain. It prevents symptoms of opioid withdrawal, reduces opioid cravings and blocks the euphoric effects of short-acting opioids such as heroin and morphine. Opioid dependence is associated with harms including an increased risk of exposure to Human Immunodeficiency Virus and Hepatitis C as well as other health, social and psychological crises. The goal of methadone treatment is harm reduction. Treatment with methadone for opioid dependence is often a long-term therapy. The Ontario College of Physicians and Surgeons estimates that there are currently 250 physicians qualified to prescribe methadone, and 15,500 people in methadone maintenance programs across Ontario. Drug testing is a clinical tool whose purpose is to provide objective meaningful information, which will reinforce positive behavioral changes in patients and guide further treatment needs. Such information includes knowledge of whether the patient is taking their methadone as prescribed and reducing or abstaining from using opioid and other drugs of abuse use. The results of drug testing can be used with behavior modification techniques (contingency management techniques) where positive reinforcements such as increased methadone take-home privileges, sustained employment or parole are granted for drug screens negative for opioid use, and negative reinforcement including loss of these privileges for drug screens positive for opioid used. Body fluids including blood, oral fluid, often referred to as saliva, and urine may contain metabolites and the

    An important interaction between opioid and dopamine systems has been indicated, and using opioids may negatively affect cognitive functioning. Memantine, a medication for Alzheimer's disease, increasingly is being used for several disorders and maybe important for cognitive improvement. Opioid-dependent patients undergoing methadone-maintenance-therapy (MMT) and healthy controls (HCs) were recruited. Patients randomly assigned to the experimental (5 mg/day memantine (MMT+M) or placebo (MMT+P) group: 57 in MMT+M, 77 in MMT+P. Those completed the cognitive tasks at the baseline and after the 12-week treatment were analyzed. Thirty-seven age- and gender-matched HCs, and 42 MMT+P and 39 MMT+M patients were compared. The dropout rates were 49.4% in the MMT+P and 26.3% in the MMT+M. Both patient groups' cognitive performances were significantly worse than that of the HCs. After the treatment, both patient groups showed improved cognitive performance. We also found an interaction between the patient groups and time which indicated that the MMT+M group's post-treatment improvement was better than that of the MMT+P group. Memantine, previously reported as neuroprotective may attenuate chronic opioid-dependence-induced cognitive decline. Using such low dose of memantine as adjuvant treatment for improving cognitive performance in opioid dependents; the dose of memantine might be a worthy topic in future studies. PMID:25989606

    Background: As one of the most important components of harm reduction strategy for high-risk groups, following the HIV epidemics, Methadone Maintenance Treatment (MMT) has been initiated in prisoners since 2003. In this paper, we aimed to assess the advantages and shortcomings of the MMT program from the perspective of people who were involved with the delivery of prison healthcare in Iran. Methods: On the basis of grounded theory and through conducting 14 Focus Group Discussions (FGDs), 7 FGDs among physicians, consultants, experts, and 7 FGDs among directors and managers of prisons (n= 140) have been performed. The respondents were asked about positive and negative elements of the MMT program in Iranian prisons. Results: This study included a total of 48 themes, of which 22 themes were related to advantages and the other 26 were about shortcomings of MMT programs in the prisons. According to participants’ views "reduction of illegal drug use and high-risk injection", "reduction of potentially high-risk behaviors" and "making positive attitudes" were the main advantages of MMT in prisons, while issues such as "inaccurate implementation", "lack of skilled manpower" and "poor care after release from prison" were among the main shortcomings of MMT program. Conclusions: MMT program in Iran’s prisons has achieved remarkable success in the field of harm reduction, but to obtain much more significant results, its shortcomings and weaknesses must be also taken into account by policy-makers.

    Although many studies have found an association between harm reduction interventions and reductions in incidence rates of Human Immunodeficiency Virus (HIV) infection, scant research explores the effects of harm reduction cross-nationally. This study used a year- and country-level fixed effects model to estimate the potential effects of needle-and-syringe programs (NSPs) and methadone maintenance therapy (MMT) on incidence rates of HIV in the general population and among people who inject drugs (PWID), in a sample of 28 European nations. After adjusting for Gross Domestic Product (GDP) and total expenditures on healthcare, we identified significant associations between years of MMT and NSP implementation and lower incidence rates of HIV among PWID and the general population. In addition to years of implementation of NSP and MMT, the greater proportion of GDP spent on healthcare was associated with a decrease in logged incidence rates of HIV. The findings of this study suggest that MMT and NSP may reduce incidence rates of HIV among PWID cross-nationally. The current study opens a new avenue of exploration, which allows for a focus on countrywide policies and economic drivers of the epidemic. Moreover, it highlights the immense importance of the adoption of harm reduction programs as empirically-based health policy as well as the direct benefits that are accrued from public spending on healthcare on incidence rates of HIV within the general population and among subpopulations of PWID.

    Objective: To assess concurrent heroin use and correlates among Methadone Maintenance Treatment (MMT) clients in Guangdong Province, China. Method: Demographic and drug use data were collected with a structured questionnaire, and MMT information was obtained from the MMT clinic registration system in Guangdong. Human immunodeficiency virus (HIV-) and hepatitis C virus (HCV) infected status and urine morphine results were obtained from laboratory tests. Logistic regressions were employed to investigate the factors associated with concurrent heroin use. Results: Among the 6848 participants, 75% continued using heroin more than once during the first 12 months after treatment initiation. Concurrent heroin use was associated with inharmonious family relationship (OR (odds ratio) = 1.49, 95% CI (confidence intervals): 1.24–1.78), HIV positivity (OR = 1.25, 95% CI: 1.01–1.55), having multiple sex partners (OR = 1.34, 95% CI: 1.07–1.69), having ever taken intravenous drugs (OR = 0.81, 95% CI: 0.69–0.95), higher maintenance dose (OR = 1.13, 95% CI: 1.01–1.28) and poorer MMT attendance (OR<20% = 1.32, 95% CI: 1.13–1.53; OR20%– = 1.33, 95% CI: 1.14–1.54; OR50%– = 1.69, 95% CI: 1.44–2.00). Among those who used heroin concurrently, the same factors, and additionally being older (OR35– = 1.26, 95% CI: 1.11–1.43; OR≥45 = 1.63, 95% CI: 1.30–2.05) and female (OR = 1.60, 95% CI: 1.28–2.00), contribute to a greater frequency of heroin use. Conclusions: Concurrent heroin use was prevalent among MMT participants in Guangdong, underscoring the urgent needs for tailored interventions and health education programs for this population.

    Background: Self-efficacy is the belief that one has the ability to implement the behaviors needed to produce a desired effect. There has been growing interest in the role of self-efficacy as a predictor and/or mediator of treatment outcome in a number of domains. Procrastination is a self-regulatory failure, defined as the voluntary delay of an intended course of action despite expecting to be worse off for the delay. Behavioral procrastination is a self-sabotage strategy that allows people to shift blame and avoid action; the decisional procrastination strategy is to put off making a decision when dealing with conflicts or choices. Procrastination has a great role in quitting drug addiction. Objectives: The aim of this study was to determine the relationship between procrastination and self-efficacy and other factors among intravenous drug users. Patients and Methods: This cross-sectional study was conducted on 178 intravenous drug users in the behavioral disease counseling, health center in Sari city, Mazandaran province, Iran, in 2013. The samples were selected through census sampling, descriptive and inferential statistics were used to measure the properties of distribution that depicts a set of data shown as frequency distribution tables, while for the mean and standard deviation, chi-square, Fisher and Spearman-Brown coefficients were used to analyze the data. Results: The mean age of the participants was 43 years. Seventy-two percent of them were married and opium was the first drug used. The first substance used in them was 54% of opium, 33% cannabis and 5% alcohol and 79% smoking. The reason of the first drug use in 32% of the subjects was temptation and in 10% a friend’s influence. The mean age of the first drug use was 23 years, and the frequency was 2 times per day. All of them had relapse at least once. Seven percent of them currently use other materials (2% crystal, 5% alcohol and opium and crack) both in methadone treatment. Behavioral

    Background Methadone maintenance treatment (MMT) has been available in Guangdong province, China since 2006. This study aims to estimate the prevalence levels of HIV, Hepatitis C (HCV), Tuberculosis (TB) and their co-infections and associated demographic and risk behaviours among MMT entrants. Method A total of 2296 drug users at the time of their MMT enrolment were recruited from four clinics during 2006-2011. Participants’ demographic characteristics, infection status and self-reported high-risk drug-use and sexual behaviours were surveyed. Log-linear contingency analysis was employed to investigate the demographic and behavioural differences between gender and drug-user type, while multivariate regression analysis was used to identify the associated factors of HIV, HCV and TB infections. Results Female drug users demonstrate significantly higher frequency of daily drug consumption (Log-linear contingency analysis, G2=10.86, p=0.013) and higher proportion of having had sex in the past three months (G2=30.22, p<0.001) than their male counterparts. Among injecting drug users, females also inject (χ2=16.15, p=0.001) and share syringes (χ2=13.24, p=0.004) more frequently than males. Prevalence of HIV, HCV and TB among MMT entrants are 6.3%, 78.7% and 4.4% respectively. Co-infections of HIV/HCV, HIV/TB, HCV/TB and HIV/HCV/TB reportedly infect 5.6%, 0.5%, 3.8% and 0.3% of study participants. Infection risks of HIV, HCV and TB are consistently associated with increasing length of drug use, injecting drugs, financial dependence and reduced sexual activities. Conclusion Injecting drug use is the major contributing factor in prevalence levels of HIV, HCV and TB among MMT entrants. Female drug users are more disadvantaged in their social status and risk-taking in their drug use behaviours than males. PMID:24116185

    Over the last 10 years we have registered in our district (about 500,000 inhabitants) 36 cases of fatal methadone poisoning, involving both patients on treatment and naive subjects: this is a significant increase of deaths due to methadone use, misuse or abuse compared with previous years. Twenty-four patients (66.7%) were on methadone maintenance programs for heroin detoxification, while 12 (33.3%) were taking the drug without a medical prescription. The average blood concentration of methadone in patients undergoing a maintenance program was 1.06 mg/L (0.21-3.37 mg/L), against 0.79 mg/L (0.2-3.15 mg/L) in those taking the non-prescribed drug. Since 111 heroin-related deaths were recorded in our district in the same period, the fact that there appear to be many methadone deaths (about a third of heroin-related deaths) cannot be overlooked. The aim of this work is to understand the possible reasons for such a large number of methadone-related deaths. On this subject, we have noticed that risks associated with methadone intake are often underestimated by clinicians prescribing the drug: sometimes methadone is prescribed without taking into account patient's tolerance to opiates, and a large number of subjects enrolled in methadone maintenance programs in Italy, have also been given take-home doses, thus increasing the risk of abuse and diversion.

    2014-01-01

    Background HIV-, HCV- and HIV/HCV co-infections among drug users have become a rapidly emerging global public health problem. In order to constrain the dual epidemics of HIV/AIDS and drug use, China has adopted a methadone maintenance treatment program (MMTP) since 2004. Studies of the geographic heterogeneity of HIV and HCV infections at a local scale are sparse, which has critical implications for future MMTP implementation and health policies covering both HIV and HCV prevention among drug users in China. This study aimed to characterize geographic patterns of HIV and HCV prevalence at the township level among drug users in a Yi Autonomous Prefecture, Southwest of China. Methods Data on demographic and clinical characteristics of all clients in the 11 MMTP clinics of the Yi Autonomous Prefecture from March 2004 to December 2012 were collected. A GIS-based geographic analysis involving geographic autocorrelation analysis and geographic scan statistics were employed to identify the geographic distribution pattern of HIV-, HCV- and co-infections among drug users. Results A total of 6690 MMTP clients was analyzed. The prevalence of HIV-, HCV- and co-infections were 25.2%, 30.8%, and 10.9% respectively. There were significant global and local geographic autocorrelations for HIV-, HCV-, and co-infection. The Moran’s I was 0.3015, 0.3449, and 0.3155, respectively (P < 0.0001). Both the geographic autocorrelation analysis and the geographic scan statistical analysis showed that HIV-, HCV-, and co-infections in the prefecture exhibited significant geographic clustering at the township level. The geographic distribution pattern of each infection group was different. Conclusion HIV-, HCV-, and co-infections among drug users in the Yi Autonomous Prefecture all exhibited substantial geographic heterogeneity at the township level. The geographic distribution patterns of the three groups were different. These findings imply that it may be necessary to inform or invent

    Maintenance therapy with methadone or buprenorphine-based regimens reduces opioid dependence and associated harms. The perception that methadone is more effective than buprenorphine for maintenance treatment has been based on low buprenorphine doses and excessively slow induction regimens used in early buprenorphine trials. Subsequent studies show that the efficacy of buprenorphine sublingual tablet (Subutex®) or buprenorphine/naloxone sublingual tablet (Suboxone®) is equivalent to that of methadone when sufficient buprenorphine doses, rapid induction, and flexible dosing are used. Although methadone remains an essential maintenance therapy option, buprenorphine-based regimens increase access to care and provide safer, more appropriate treatment than methadone for some patients.

  16. The nature of methadone diversion in England: a Merseyside case study

    PubMed Central

    2012-01-01

    Background Methadone maintenance treatment (MMT) is a key element in treatment for opiate addiction; however concerns about the diversion of methadone remain. More current empirical data on methadone diversion are required. This research investigated the market for diverted methadone in Merseyside, UK, in order to provide a case study which can be transferred to other areas undertaking methadone maintenance treatment on a large scale. Methods Questionnaires were completed (in interview format) with 886 past year users of methadone recruited both in and out of prescribing agencies. Topic areas covered included current prescribing, obtaining and providing methadone, reasons for using illicit methadone and other drug use. Results Large proportions of participants had obtained illicit methadone for use in the past year with smaller proportions doing so in the past month. Proportions of participants buying and being given methadone were similar. Exchange of methadone primarily took place between friends and associates, with 'dealers' rarely involved. Gender, age, whether participant's methadone consumption was supervised and whether the aims of their treatment had been explained to them fully, influenced the extent to which participants were involved in diverting or using diverted methadone. Conclusion Methadone diversion is widespread although drug users generally do not make use of illicit methadone regularly (every month). The degree of altruism involved in the exchange of methadone does not negate the potential role of this action in overdose or the possibility of criminal justice action against individuals. Treatment agencies need to emphasise these risks whilst ensuring that treatment aims are effectively shared with clients to ensure adherence to treatment. PMID:22243982

    This study investigated association between post-traumatic stress disorder (PTSD) and a 1-year follow-up heroin use among female clients in methadone clinics in Israel. Participants were 104 Israeli female clients from four methadone clinics (Mean age = 39.09, SD = 8.61) who reported victimization to childhood sexual abuse. We tested traces in urine of these female clients for heroin a year preceding and a year following the assessment of their PTSD. Results show that 54.2% reported symptoms that accedes the DSM-IV criteria for PTSD. We found that among childhood victimized women PTSD is associated with more frequent use of heroin at a 1-year follow-up even after controlling for duration of the stay at the clinic, background, other traumatic experiences and heroin use a year prior the assessment of their PTSD. This study shows the potential long-run negative consequences of childhood sexual abuse. Not only are these sexually abused women trapped into drug dependence and addiction, they cannot break the vicious cycle of continuing the use of illicit drugs even when treated for their addiction. One major practice implication is that treatment for PTSD proven efficacious will be provided in the methadone and other drug treatment services. PMID:20938876

    Objective Methadone maintenance treatment (MMT) has been implemented in China since 2004 and has expanded into a nationwide programme. This study aims to evaluate changes in social functioning, family relations and drug-related criminal behaviour among MMT clients in China. Design Systematic review and meta-analysis. Methods Both English and Chinese literature databases, including PubMed, Chongqing VIP Chinese Science and Technology Journals Database (CQVIP), China National Knowledge Infrastructure (CNKI) and Wanfang Data, were comprehensively searched over the period 2004–2014 for studied indicators. Study selection, quality assessment and data extraction were conducted according to the PRISMA (preferred reporting items for systematic reviews and meta-analyses) Statement. Meta-analyses were conducted using Comprehensive Meta-Analysis Biostat software. Results Thirty-eight articles were included in this review (1 in English and 37 in Chinese). The self-reported arrest rate decreased from 13.1% (95% CI 9.1% to 18.5%) at baseline to 3.4% (95% CI 1.5% to 7.7%) and 4.3% (95% CI 1.6% to 11.4%) after 6 and 12 months of MMT intervention, respectively. The rate of drug selling decreased from 7.6% (95% CI 3.8% to 14.8%) at baseline to 1.9% (95% CI 0.6% to 6.2%) and 3.0% (95% CI 1.0% to 8.9%) after 6 and 12 months of intervention, respectively. Similarly, the rates of selling sex for drugs and drug-related crime decreased from 5.3% (95% CI 2.4% to 11.1%) and 9.9% (95% CI 6.8% to 14.2%) at baseline to 1.1% (95% CI 0.5% to 2.3%) and 3.4% (95% CI 2.5% to 4.5%) at 6 months, then to 0.8% (95% CI 0.3% to 1.9%) and 3.4% (95% CI 0.8% to 13.1%) at 12 months after treatment initiation, respectively. In contrast, the rate of employment of clients and the proportion of clients having a good relationship with their family increased substantially from 26.4% (95% CI 22.9% to 30.1%) and 37.9% (95% CI 32.0% to 44.2%) to 41.6% (95% CI 36.6% to 48.0%) and 59.6% (95% CI 48.1% to 70

    Objective: Methadone poisoning can occur accidentally or intentionally for suicide or homicide purposes. The aim of this study was to evaluate the epidemiological and clinical manifestations of Methadone poisoning. Methods: A descriptive analytical study was performed from 2010 to 2012 in the poisoning emergency and clinical toxicology departments of Noor hospital affiliated with Isfahan University of Medical Sciences (Isfahan, Iran). All patients with Methadone poisoning within this period of time were investigated. Different variables were recorded in a checklist. Findings: A total of 385 patients were studied. About 85.7% had ingested only Methadone and 14.3% had ingested other medications with Methadone. Mean ± standard deviation of the age was 32.1 ± 15 years (range: 1-90). Most of the patients were male (76.4%). Nearly 40% of the patients were narcotic addicts, 25.5% were addicts under surveillance of Methadone maintenance therapy centers and 34.5% were non-addicts. Intentional poisoning was observed in most of the patients (57.7%). Most of the patients had a low level of consciousness on admission (58.2%). Respiratory depression and hypotension was observed in 35.6% and 12.7% of the cases as the most common symptoms. Regarding vital signs, there was a significant difference in respiratory rate on admission among different evaluated groups (P = 0.02). Length of hospital stay was 18.79 ± 0.72 h (range: 4-240 h, median: 15 h). About 57 patients (25.8%) from the intentionally poisoned patients and 19 patients (12.3%) from the unintentionally poisoned patients had a history of psychiatric disorder (P = 0.001). Most of the patients survived without complications. Conclusion: Addiction, age, gender, attempt to suicide and a history of psychiatric disorder were of the most important factors effective in Methadone poisoning, which should be considered in the public training and prevention of poisoning.

    To answer the question whether or not therapeutic methadone doses significantly reduce traffic-related performance of drivers on medically supervised methadone programmes, 34 methadone substitution patients, all of them volunteers, were subjected to a test series: the focus of the study was a psychophysical test battery consisting of 10 individual performance tests to assess essential functions with regard to driving ability, such as concentration, attention, reaction capability, memory, perception and sensorimotor coordination. In evaluating the results of the psychophysical tests, multiple drug use and subjective methadone influence at the time of the examination were taken into consideration but current methadone blood level was neglected. The results were compared to those of a control group. The methadone group (n = 34) consisted of 25 men and 9 women aged between 18 and 38. At the time of the study, the majority of the test persons (29) were on low dosage methadone maintenance (up to 60 mg/day). In the urine samples of approximately 2/3 of the test persons, evidence was found for multiple drug use together with other psychotropic substances, the most frequent (14) being cannabis metabolites. Referring to their driving practices, a mere 4 out of 29 drivers had not committed any driving offences. A comparison of the psychophysical performance of the whole methadone group (n = 34) with a control group demonstrated that the methadone substitution patients achieved rather lower results in almost all variables. These performance deficits were particularly conspicuous in sustained attention, sensorimotor coordination and reaction capability. 12 "methadone only" participants, i.e. methadone probands without any additional consumption of psychotropic substances showed-partly considerably-better performance than the methadone group as a whole and also achieved normal results in relation to the test norm. Nevertheless, once again, results tended to be of lower level in

    OBJECTIVES: This study sought to track changes in US heroin prices from 1988 to 1995 and to determine whether changes in the affordability of heroin were associated with changes in the use of heroin by users seeking methadone treatment, as indexed by methadone dose levels. METHODS: Data on the price of heroin were from the Drug Enforcement Administration; data on methadone doses were from surveys conducted in 1988, 1990, and 1995 of 100 methadone maintenance centers. Multivariable models that controlled for time and city effects were used to ascertain whether clinics in cities where heroin was less expensive had patients receiving higher doses of methadone, which would suggest that these patients had relatively higher physiological levels of opiate addiction owing to increased heroin use. RESULTS: The amount of pure heroin contained in a $100 (US) purchase has increased on average 3-fold between 1988 and 1995. The average dose of methadone in clinics was positively associated with the affordability of local heroin (P < .01). CONCLUSIONS: When heroin prices fall, heroin addicts require more methadone (a heroin substitute) to stabilize their addiction--evidence that they are consuming more heroin. PMID:10224975

    Many clients who undergo methadone maintenance (MM) treatment for heroin and other opiate dependence prefer abstinence from methadone. Attempts at methadone detoxification are often unsuccessful, however, due to distressing physical as well as psychological symptoms. Outcomes from a MM client who voluntarily participated in an Acceptance and Commitment Therapy (ACT) – based methadone detoxification program are presented. The program consisted of a 1-month stabilization and 5-month gradual methadone dose reduction period, combined with weekly individual ACT sessions. Urine samples were collected twice weekly to assess for use of illicit drugs. The participant successfully completed the program and had favorable drug use outcomes during the course of treatment, and at the one-month and one-year follow-ups. Innovative behavior therapies, such as ACT, that focus on acceptance of the inevitable distress associated with opiate withdrawal may improve methadone detoxification outcomes. PMID:20628479

    A new technique for simultaneous stereoselective kinetic studies of methadone enantiomers was developed using three deuterium-labeled forms of methadone and GLC-chemical-ionization mass spectrometry. A racemic mixture (1:1) of (R)-(-)-(2H5)methadone (l-form) and (S)-(R)-(2H3)methadone (d-form) was administered orally in place of a single daily dose of unlabeled (+/-)-(2H0)methadone in long-term maintenance patients. Racemic (+/-)-(2H8)methadone was used as an internal standard for the simultaneous quantitation of (2H0)-, (2H3)-, and (2H5)methadone in plasma and urine. A newly developed extraction procedure, using a short, disposable C18 reversed-phase cartridge and improved chemical-ionization procedures employing ammonia gas, resulted in significant reduction of the background impurities contributing to the ions used for isotopic abundance measurements. These improvements enabled the measurement of labeled plasma methadone levels for 120 hr following a single dose. This methodology was applied to the study of methadone kinetics in two patients; in both patients, the analgesically active l-enantiomer of the drug had a longer plasma elimination half-life and a smaller area under the plasma disappearance curve than did the inactive d-form.

  7. Are empty methadone bottles empty? An analytic study

    PubMed Central

    2014-01-01

    Background Methadone maintenance treatment is the most widely prescribed treatment for opiate dependence with proven benefits for patients. In naïve users or in case of recreational misuse, methadone can be a source of potentially lethal intoxications, resulting in fatal overdoses. A few cases of infantile intoxications have been described in the literature, some of which resulted in death. Nowadays, more than 50,000 bottles are used every day in France, most of which are thrown away in the bin. Relatives at home, especially children, can have access to these empty bottles. This study aims to determine whether the residual quantity of methadone in the bottles is associated with a risk of intoxication for someone who has a low tolerance to opiates, such as a child. Methods The methadone dosage left in a sample of 175 bottles recapped after use by the patients taking their maintenance treatment in an addiction treatment program centre was analysed during a 2-week period in March 2013. Results The mean residual quantity of methadone left in each bottle after use is 1.9 ± 1.8 mg and 3.3 ± 2.4 mg in the sample of 60 mg bottles. Conclusions There is a potential danger of accidental overdose with empty bottles of methadone syrup, especially for children. To take into account this hazard, several harm reduction strategies can be proposed, such as favouring the taking of the treatment within the delivery centres rather than the ‘take home’ doses, asking methadone users to bring back their used bottles, and raising patients’ awareness of the intoxication risks and the necessary everyday precautions. For stable patients with take home methadone, the use of capsules could be considered. PMID:24990630

    BACKGROUND Previous research has suggested possible sex-related differences in executive functioning among cocaine users; however, no studies specifically explain sex-related differences in neurocognitive impairment (NCI) among cocaine users receiving clinical care. Knowledge about this association can aid in the development of targeted prevention strategies to reduce adverse health outcomes. This study was designed to examine the sex-related differences in NCI among high-risk cocaine users receiving substance-abuse treatment. METHODS The Neuropsychological Impairment Scale (NIS) was administered to 199 cocaine users (98 men; 101 women), receiving methadone maintainance treatment, to assess self-reported NCI by identifying the patients’ awareness of neuropsychological symptoms. We used T-test comparison to find differences in NCI between men and women and multiple regression analysis to explore the relative contribution of sex to NCI. RESULTS Consistent with prior work, high NCI was evident within this sample, as indicated by high scores on most of the NIS subscales. Women reported greater impairment than men, as evidenced by significantly higher scores on several NIS subscales, after controlling for demographic and other confounding variables. Interestingly, cocaine craving significantly predicted NCI among men but not among women, as suggested by the significant association between cocaine craving and all except one of the NIS subscales. CONCLUSIONS These findings suggest that cocaine users enter into treatment with a range of NCI – with women having significantly more neurocognitive deficits than men – that may contribute to differential treatment outcomes. This highlights the need to include additional services such as neuropsychological screening and sex-specific treatment programs to optimally reduce adverse health outcomes in these high-risk, cognitively impaired patients.

    Both heroin-addicted individuals and methadone maintenance patients are likely to face untreated opioid withdrawal while incarcerated. Limited research exists concerning the withdrawal experiences of addicted inmates and their impact on individuals' attitudes and plans concerning drug abuse treatment. In the present study, 53 opioid dependent adults (32 in methadone treatment and 21 out of treatment) were interviewed in an ethnographic investigation of withdrawal experiences during incarceration. When treatment for opioid withdrawal was unavailable, detoxification experiences were usually described as negative and were often associated with a variety of unhealthy behaviors designed to relieve withdrawal symptoms. Negative methadone withdrawal experiences also negatively influenced participants' receptivity to seeking methadone treatment upon release. A minority of participants took a positive view of their withdrawal experience and saw it as an opportunity to detox from heroin or discontinue methadone. Findings support the importance of providing appropriate opioid detoxification and/or maintenance therapy to opioid-dependent inmates. PMID:19705676

    Gender-related differences in the pharmacological effects of drug are an emerging topic. This review examines gender differences in both pharmacokinetic and pharmacodynamic aspects of methadone, a long-acting opioid agonist that is prescribed as a treatment for opioid dependence and the management of chronic pain. Method: We performed a search in the Medline database from 1990 to 2014 in order to find published literature related to gender differences in pharmacokinetics (PK) and pharmacodynamics (PD) of methadone. Results: None of the studies were carried out with the primary or secondary aim to identify any gender differences in the pharmacokinetic profile of methadone. Importantly; high inter-subjects variability in PK parameters was found also intra female population. The reported differences in volume of distribution could be ascribed to the physiological differences between men and women in body weight and composition, taking into account that the dose of methadone was established irrespective of body weight of patients (Peles and Adelson, 2006). On the other hand, the few studies present in literature found no gender difference in some direct pharmacodynamic parameters. Some reports have suggested that female gender is associated with an increased risk for long-QT-related cardiac arrhythmias in methadone maintenance subjects. Conclusion: Even though it may be too simplistic to expect variability only in one parameter to explain inter-individual variation in methadone response, we believe that a better knowledge of gender-related differences might have significant implications for better outcomes in opioid dependence substitution therapy in women.

    Methadone maintenance treatment is the most widely available pharmacotherapy for opioid addiction and has been shown over a period of 40 years to be an effective and safe treatment. While women comprise approximately 40% of clients currently being treated in MMT programs, comparatively little research geared specifically toward this group has been published. This article begins with an overview of neurobiological studies on opioid addiction, including a discussion of gender differences, followed by a review of the pharmacology of methadone The authors then examine the particular needs and differences of women being treated in MMTs, including co-dependence with other substances, women’s health issues and psychosocial needs unique to this population. In conclusion, research shows that women have different substance abuse treatment needs in comparison to their male counterparts. One New York City MMT program that has attempted to address these differences is highlighted. PMID:20407977

    Narcotic withdrawal is often accompanied by an atypical depression which responds to resumption of narcotics. It was hypothesized that methadone might exert its antidepressant effects through monoamine oxidase (MAO) inhibition. The current study examined /sub 3/H-methadone distribution in rat brain and effects on regional MAO activity with acute doses (2.5 mg/kg) which approximate those found during chronic methadone maintenance in man. Limbic areas (amygdala, basomedial hypothalamus, caudate-putamen, hippocampus, preoptic nucleus), as well as pituitary and liver were assayed for MAO activity and methadone concentration. MAO activities did not differ significantly in acute methadone or saline-treated cage-mates at 1 or 24 hr. The concentrations of methadone at 1 hr ranged between 17 and 223 ng/100 mg wet wt tissue in the preoptic nucleus and pituitary, respectively. No significant correlation was found between change in MAO activity (MAO methadone/MAO saline) and methadone concentration in any region at 1 or 24 hr. This study does not support the hypothesis that methadone acts as an antidepressant through MAO inhibition, at least not following acute administration of this exogenous opioid.

    Summary Background Methadone is an effective treatment for opioid dependence. When people who are receiving methadone maintenance treatment for opioid dependence are incarcerated in prison or jail, most US correctional facilities discontinue their methadone treatment, either gradually, or more often, abruptly. This discontinuation can cause uncomfortable symptoms of withdrawal and renders prisoners susceptible to relapse and overdose on release. We aimed to study the effect of forced withdrawal from methadone upon incarceration on individuals’ risk behaviours and engagement with post-release treatment programmes. Methods In this randomised, open-label trial, we randomly assigned (1:1) inmates of the Rhode Island Department of Corrections (RI, USA) who were enrolled in a methadone maintenance-treatment programme in the community at the time of arrest and wanted to remain on methadone treatment during incarceration and on release, to either continuation of their methadone treatment or to usual care—forced tapered withdrawal from methadone. Participants could be included in the study only if their incarceration would be more than 1 week but less than 6 months. We did the random assignments with a computer-generated random permutation, and urn randomisation procedures to stratify participants by sex and race. Participants in the continued-methadone group were maintained on their methadone dose at the time of their incarceration (with dose adjustments as clinically indicated). Patients in the forced-withdrawal group followed the institution’s standard withdrawal protocol of receiving methadone for 1 week at the dose at the time of their incarceration, then a tapered withdrawal regimen (for those on a starting dose >100 mg, the dose was reduced by 5 mg per day to 100 mg, then reduced by 3 mg per day to 0 mg; for those on a starting dose ≤100 mg, the dose was reduced by 3 mg per day to 0 mg).

    (1) Methadone accounted for 2 percent of painkiller prescriptions and more than 30 percent of prescription painkiller deaths in 2009. (2) Data suggest that the rise in deaths from methadone overdose is not related to its use in treating drug abuse but, rather, to its use for pain management. (3) Preferred drug lists in most Medicaid programs identify methadone as a preferred drug for managing chronic pain, but most experts do no recommend it as a first choice. PMID:25556261

    AIMS This study examines the frequency and severity of arrest charges among heroin addicts randomly assigned to either interim methadone maintenance (IM) or to remain on a waiting list for methadone treatment. It was hypothesized that IM participants would have a: 1) lower number of arrests at 6 and 12 months and 2) lower mean crime severity scores at 6 and 12 months post-baseline. METHODS Available official arrest data were obtained for all 319 study participants for a period of 2 years before and after study enrollment. Crime severity ratings of charges were made using an established measure of crime severity. FINDINGS Participants randomly assigned to IM as compared to those on a waiting list had a significant reduction in number of arrests at 6 but not at 12 months from study enrollment. There were no significant differences in whether participants were arrested for a more severe crime but frequency of severe crime was relatively low in both groups. Additional post hoc analyses based on whether participants were in methadone treatment at 4 and 10 months after original random assignment to treatment condition revealed that those participants not in treatment at these follow-up assessment points were significantly more likely to be arrested and to have a higher mean crime severity rating at 12 and 24 months post-baseline assessment. CONCLUSIONS IM as compared to the waiting list condition, had a significant reduction in number of officially- recorded arrests from baseline to 6 months post-baseline. Those who were enrolled in methadone treatment at the 4 and 10 month follow-up assessment, regardless of initial assignment, had fewer arrests at 12 and 24 months post-baseline. PMID:19443133

    Objective: Priapism is defined by persistent, painful penile erection which occurs without sexual stimulation. Methadone is used as an analgesic and is also used in detoxification and maintenance protocol for opioid dependence treatment. Here we will report a case of a male with priapism after rapid discontinuation doses of methadone. Case presentation: The case was a young married male who referred to a psychiatry clinic due to long-time spontaneous erections. The patient had no history of mental disorders, trauma or sickle cell anemia. He used to smoke opium for five years and used methadone for four years at a dose of 17 cc daily, which he abruptly discontinued. Then he often experienced spontaneous and painful erections without physical or mental stimulation that caused him shame and embarrassment. Conclusion: In this case, chronology indicates that rapid discontinuation of methadone was possibly responsible for the occurrence of priapism. This may have happened due to a compensatory reaction to methadone side effect of erectile dysfunction, followed by its rapid withdrawal. PMID:26884791

    Although the efficacy of methadone maintenance treatment (MMT) in opioid dependence disorder has been well established, the influence of methadone pharmacokinetics in dose requirement and clinical outcome remains controversial. The aim of this study is to analyze methadone dosage in responder and nonresponder patients considering pharmacogenetic and pharmacokinetic factors that may contribute to dosage adequacy. Opioid dependence patients (meeting Diagnostic and Statistical Manual of Mental Disorders, [4th Edition] criteria) from a MMT community program were recruited. Patients were clinically assessed and blood samples were obtained to determine plasma concentrations of (R,S)-, (R) and (S)- methadone and to study allelic variants of genes encoding CYP3A5, CYP2D6, CYP2B6, CYP2C9, CYP2C19, and P-glycoprotein. Responders and nonresponders were defined by illicit opioid consumption detected in random urinalysis. The final sample consisted in 105 opioid dependent patients of Caucasian origin. Responder patients received higher doses of methadone and have been included into treatment for a longer period. No differences were found in terms of genotype frequencies between groups. Only CYP2D6 metabolizing phenotype differences were found in outcome status, methadone dose requirements, and plasma concentrations, being higher in the ultrarapid metabolizers. No other differences were found between phenotype and responder status, methadone dose requirements, neither in methadone plasma concentrations. Pharmacokinetic factors could explain some but not all differences in MMT outcome and methadone dose requirements. PMID:21589866

    Incarceration is a common experience for individuals with opioid use disorder, including those receiving medication assisted treatments (MAT), such as buprenorphine or methadone. In the United States, MAT is rarely available during incarceration. We were interested in whether challenges with methadone maintenance treatment during incarceration affected subsequent attitudes toward MAT following release. We conducted semi-structured interviews with 21 formerly incarcerated individuals with opioid use disorder in community substance abuse treatment settings. Interviews were audio recorded, transcribed, and analyzed using a grounded theory approach. Themes that emerged upon iterative readings of transcripts were discussed by the research team. The three main themes relating to methadone were: 1) rapid dose reduction during incarceration; 2) discontinuity of methadone during incarceration; and 3) post incarceration aversion to methadone. Participants who received methadone maintenance treatment prior to incarceration reported severe and prolonged withdrawal symptoms from rapid dose reductions or disruption of their methadone treatment during incarceration. The severe withdrawal during incarceration contributed to a subsequent aversion to methadone and adversely affected future decisions regarding reengagement in MAT. Though MAT is the most efficacious treatment for opioid use disorder, current penal policy, which typically requires cessation of MAT during incarceration, may dissuade individuals with opioid use disorder from considering and engaging in MAT after release from incarceration.

    Rats given 2-day oral administration of methadone (15 mg/kg, twice on day 1 and once on day 2) by gastric tube developed dispositional tolerance to methadone analgesia as demonstrated by a decrease in analgesic response and by an increase in methadone metabolism. The increased metabolism of methadone was evidenced by a decrease in brain concentration of /sup 14/C-methadone and increases in the percentages of total /sup 14/C in liver or urine as /sup 14/C-water-soluble metabolites (/sup 14/C-WSM) after the rats were challenged with a test dose of /sup 14/C-methadone. Two-day pretreatment with a combination of desipramine (DMI) (10 mg/kg, ip) and methadone (15 mg/kg, po) enhanced the development of dispositional tolerance to methadone analgesia which was evidenced by a greater decrease in the brain concentration of methadone and a greater increase in methadone metabolism as compared to those changes in rats pretreated with only methadone. Repeated treatment with DMI alone neither decreased the analgesic effect of methadone nor stimulated methadone metabolism. It is suggested that DMI given together with methadone promoted the induction of methadone metabolism in the liver by prolonging the enzyme-stimulating state of methadone, thus enhancing the development of dispositional tolerance to methadone. 20 references, 1 figure, 1 table.

    Methadone and buprenorphine are widely used for treating people with opioid dependence, including pregnant women. Prenatal exposure to opioids has devastating effects on the development of human fetuses and may induce long-term physical and neurobehavioral changes during postnatal maturation. This study aimed at comparing the behavioral outcomes of young rats prenatally exposed to buprenorphine, methadone, and morphine. Pregnant Sprague-Dawley rats were administered saline, morphine, methadone, and buprenorphine during embryonic days 3–20. The cognitive function, social interaction, anxiety-like behaviors, and locomotor activity of offsprings were examined by novel object recognition test, social interaction test, light–dark transition test, elevated plus-maze, and open-field test between 6 weeks and 10 weeks of age. Prenatal exposure to methadone and buprenorphine did not affect locomotor activity, but significantly impaired novel object recognition and social interaction in both male and female offsprings in the same manner as morphine. Although prenatal exposure to methadone or buprenorphine increased anxiety-like behaviors in the light–dark transition in both male and female offsprings, the effects were less pronounced as compared to that of morphine. Methadone affected elevated plus-maze in both sex, but buprenorphine only affected the female offsprings. These findings suggest that buprenorphine and methadone maintenance therapy for pregnant women, like morphine, produced detrimental effects on cognitive function and social behaviors, whereas the offsprings of such women might have a lower risk of developing anxiety disorders.

    Methadone treatment in chronic pain patients is still limited owing to misconceptions about addiction, safety, and its unique pharmacokinetic and pharmacodynamic properties. Nevertheless, patients with chronic noncancer pain are frequently treated with methadone at our Pain Centre either as the first opioid of choice, for specific pain conditions, or as a second-line opioid in patients developing tolerance or intractable side effects with other opioids. The aim of this study was to examine whether a nurse case management program of chronic pain patients treated with methadone is feasible and safe in trying to improve patients' care in an ambulatory setting. This program consisted of three phases: initial primary education session, telephone follow-up during methadone titration, and a subsequent maintenance period. The nurse case manager functioned autonomously and when required reported to and consulted the physician. The study included 75 subjects and was done over a nine-month period by completing follow-up questionnaires for every call. Of a total of 194 recorded calls, 41% were unscheduled. Forty-four percent of phone calls resulted in a methadone increase and 11% led to a decrease or cessation of methadone. No patients developed serious morbidity or mortality. Fifty-seven percent of patients were either satisfied or very satisfied with their treatment. A nurse-led case management program of methadone in chronic pain patients can improve patient care in an ambulatory setting. PMID:17723930

    We report five cases where fluvoxamine (FLVX) was added to maintenance treatment with methadone (MTD) in addict patients with affective disorders. In view of the implication of FLVX in several metabolic drug interactions, MTD plasma levels were measured before and after treatment with FLVX. A slight increase (approximately 20% of the MTD plasma level/dose ratio) occurred in two cases. In the remaining three patients, the interaction was more pronounced (40-100% increase of the MTD plasma level/dose ratio), with clinical manifestations of opiate withdrawal after stopping FLVX therapy in one case. Caution is needed when starting or stopping treatment with FLVX in patients receiving maintenance treatment with methadone. PMID:8160253

    Hospital-based neuropsychological services may provide the hospital with a new means of interfacing with the general medical community, especially neurologists and neurosurgeons. This could produce increased census through the evaluation and treatment of patients who may not have been referred to the psychiatric hospital previously. Additionally, it is a service that can be marketed to the legal community. The establishment of neuropsychological services is a relatively inexpensive project that requires little in the way of physical plant and personnel needs other than a qualified technician and neuropsychologist.

    Aims Methadone is characterized by wide intersubject variability regarding the dose needed to obtain full therapeutic response. We assessed the influence of sociodemographic, ethnic, clinical, metabolic and genotypic variables on methadone maintenance dose requirement in opioid-dependent responder patients. Methods Eighty-one stable patients (60 men and 21 women, 43.7 ± 8.1 years old, 63.1 ± 50.9 mg day−1 methadone), divided into quartiles with respect to the median daily dose, were enrolled and underwent clinical examination, treatment history and determination of liver/intestinal cytochrome P450 (CYP) 3A4 activity measured by the midazolam test, R,S-methadone trough concentration and clinically significant polymorphisms of the OPRM1, DRD2, COMT, ABCB1, CYP2B6, CYP3A5, CYP2C19 and CYP2D6 genes. Results Methadone maintenance dose was correlated to the highest dose ever used (r2 = 0.57, P < 0.0001). Fractioned methadone intake (odds ratio 4.87, 95% confidence interval 1.27–18.6, P = 0.02), bodyweight (odds ratio 1.57, 95% confidence interval 1.01–2.44, P = 0.04), history of cocaine dependence (80 vs. 44 mg day−1 in never-addict patients, P = 0.005) and ethnicity (Asian > Caucasian > African, P = 0.04) were independently associated with high-dose methadone in multiple regression analysis. A modest correlation was observed between liver/intestinal CYP3A4 activity and methadone dose at steady state (Spearman rank correlation coefficient [rs] = 0.21, P = 0.06) but not with highest dose ever used (rs = 0.15, P = 0.18) or dose-normalized R,S-methadone trough concentrations (rs = −0.05, P = 0.64). Concomitant CYP3A4 inhibitors only affected the relationship between methadone dose and R,S-methadone trough concentration. None of the genetic polymorphisms explored was predictive of the methadone maintenance dose. Conclusions Methadone maintenance dose was predicted by sociodemographic and clinical variables rather than genetic polymorphisms or liver/intestinal CYP

    Twelve male outpatients participating in a methadone maintenance treatment program were evaluated for the effects of acute administration of methadone on brain functioning (contingent negative variation or CNV), attention performance (reaction time and continuous performance test), and psychophysiological activity (heart rate and eye blink rate). Individual differences in response to methadone were assessed by classifying patients into two groups on the basis of basal CNV shapes: Type A (quick rise time) and type B (slow rise time). Methadone produced a pattern of increased electrical brain activity (CNV) and enhanced attention performance in type B patients and elevated heart rate and lowered eye blink rate in type A subjects. Results are interpreted in terms of the distraction-arousal and the eye blink-hedonia hypotheses. PMID:116287

    Contingency management (CM) is an effective treatment for promoting cocaine abstinence in patients receiving methadone maintenance. However, few studies have examined the effect of sex on treatment outcomes in this population. This study evaluated the impact of sex on longest duration of abstinence (LDA) and percent negative urine samples in 323 cocaine-using methadone patients from four randomized clinical trials comparing CM to standard methadone care. Overall, women had better treatment outcomes compared to men, demonstrated by an increase in both LDA and percentages of negative samples. Patients receiving CM also had significantly higher LDA and percentages of negative samples compared to patients receiving standard care, but sex by treatment condition effects were not significant. These data suggest that cocaine using methadone patients who are women have better substance use outcomes than men in interventions that regularly monitor cocaine use, and CM is equally efficacious regardless of sex.

    Objective Treatment with an opioid agonist such as methadone or buprenorphine is the standard of care for opioid use disorder. Persons with opioid use disorder are frequently hospitalized, and may be undertreated due to provider misinformation regarding the legality of prescribing methadone for inpatients. Using a case-based review, this article aims to describe effective management of active opioid withdrawal and ongoing opioid use disorder using methadone or buprenorphine among acutely ill, hospitalized patients. Methods We reviewed pertinent medical and legal literature and consulted with national legal experts regarding methadone for opioid withdrawal and opioid maintenance therapy in hospitalized, general medical and surgical patients, and describe a real-life example of successful implementation of inpatient methadone for these purposes. Results Patients with opioid use disorders can be effectively and legally initiated on methadone maintenance therapy or buprenorphine during an inpatient hospitalization by clinical providers and successfully transitioned to an outpatient methadone maintenance or buprenorphine clinic after discharge for ongoing treatment. Conclusions Inpatient methadone or buprenorphine prescribing is safe and evidence-based, and can be used to effectively treat opioid withdrawal and also serves as a bridge to outpatient treatment of opioid use disorders.

    It has been known that methadone maintenance treatment is the standard treatment of choice for pregnant opiate addicts. However, there are few data on newborn outcomes especially in the cross talk with other addictive agents. The present study was to investigate the effect of prenatal exposure to methadone on methamphetamine (METH)-induced behavioral sensitization as an indicator of drug addiction in later life. Pregnant rats received saline or methadone (7 mg/kg, s.c.) twice daily from E3 to E20. To induce behavioral sensitization, offspring (5 weeks old) were treated with METH (1mg/kg, i.p.) or saline once daily for 5 consecutive days. Ninety-six hours (day 9) after the 5th treatment with METH or saline, animals received a single dose of METH (1mg/kg, i.p.) or saline to induce the reinstated behavioral sensitization. Prenatal methadone treatment enhanced the level of development of locomotor behavioral sensitization to METH administration in adolescent rats. Prenatal methadone treatment also enhanced the reinstated locomotor behavioral sensitization in adolescent rats after the administration had ceased for 96 h. These results indicate that prenatal methadone exposure produces a persistent lesion in the dopaminergic system, as indicated by enhanced METH-induced locomotor behavioral sensitization (before drug abstinence) and reinstated locomotor behavioral sensitization (after short term drug abstinence) in adolescent rats. These findings show that prenatal methadone exposure may enhance susceptibility to the development of drug addiction in later life. This could provide a reference for drug usage such as methamphetamine in their offspring of pregnant woman who are treating with methadone. PMID:24157336

    To assess the views of opiate-dependent individuals about supervised methadone consumption. Three groups of opinions were sought: (i). new patients referred for assessment and treatment, using rating scales; (ii). the consensus view of the Methadone Alliance (a national users' forum); and (iii). the consensus view of a local service users' forum. All three groups expressed the view that supervised consumption has an important place in methadone treatments. Users understand the need for daily supervision of methadone and are generally willing to accept it. Users' views provide support for the introduction of flexible methadone prescribing regimes incorporating supervised consumption. Privacy in pharmacies and the possibility of moving away from supervision are important elements in an acceptable programme. Supervised consumption is an important component of safe, effective and responsible methadone prescribing. PMID:12745415

    This study examined retention rates and associated predictors of methadone maintenance treatment (MMT) duration among 128 newly admitted patients in Taiwan. A semi-structured questionnaire was used to obtain demographic and drug use history. Daily records of methadone taken and test results for HIV, HCV, and morphine toxicology were taken from a computerized medical registry. Cox regression analyses were performed to examine factors associated with MMT duration. MMT retention rates were 80.5%, 68.8%, 53.9%, and 41.4% for 3, 6, 12, and 18 months, respectively. Excluding 38 patients incarcerated during the study period, retention rates were 81.1%, 73.3%, 61.1%, and 48.9% for 3 months, 6 months, 12 months, and 18 months, respectively. No participant seroconverted to HIV and 1 died during the 18-months follow-up. Results showed that being female, imprisonment, a longer distance from house to clinic, having a lower methadone dose after 30 days, being HCV positive, and in the New Taipei city program predicted early patient dropout. The findings suggest favorable MMT outcomes of HIV seroincidence and mortality. Results indicate that the need to minimize travel distance and to provide programs that meet women’s requirements justify expansion of MMT clinics in Taiwan. PMID:25875531

    There is little information on bruxism related to illicit drug use. Prolonged drug use may damage the stomatognathic system via oral motor overactivity. The aim of the present study was to compare the rates of bruxism and temporomandibular disorders (TMDs) between prisoners with and without drug-use disorders, to evaluate the association between methadone treatment and bruxism and to assess the possible relationship between bruxism and pain. The sample included 152 male prisoners, 69 of whom were drug users maintained on methadone. All prisoners were examined by an experienced dentist and completed a questionnaire on their oral habits, with the aim of detecting signs or symptoms of TMD and/or bruxism. Additional data were collected from medical files. The prevalence of sleep bruxism and awake bruxism, but not of TMDs, was significantly higher among drug-user than non-drug user prisoners (52.2% vs. 34.9% for sleep bruxism, 59.7% vs. 30.1% for awake bruxism, and 46.3% vs. 25.6% for TMDs, respectively). Participants with awake bruxism were statistically more sensitive to muscle palpation compared with participants with sleep bruxism [rating scores (mean ± SD): 0.32 ± 0.21 vs. 0.19 ± 0.28, respectively]. An association was found between sleep bruxism and awake bruxism. It seems that there is a direct or an indirect association between methadone maintenance treatment and sleep bruxism or awake bruxism in male prisoners. PMID:27041534

    Injection drug use (IDU) continues to be a significant public health issue in the U.S. and internationally, and there is evidence to suggest that the burden of injection drug use and associated morbidity and mortality falls disproportionately on minority communities. IDU is responsible for a significant portion of new and existing HIV/AIDS cases in many parts of the world. In the U.S., the prevalence of HIV and hepatitis C virus is higher among populations of African-American and Latino injection drug users (IDUs) than among white IDUs. Methadone maintenance therapy (MMT) has been demonstrated to effectively reduce opiate use, HIV risk behaviors and transmission, general mortality and criminal behavior, but opiate-dependent minorities are less likely to access MMT than whites. A better understanding of the obstacles minority IDUs face accessing treatment is needed to engage racial and ethnic disparities in IDU as well as drug-related morbidity and mortality. In this study, we explore knowledge, attitudes and beliefs about methadone among 53 out-of-treatment Latino and African-American IDUs in Providence, RI. Our findings suggest that negative perceptions of methadone persist among racial and ethnic minority IDUs in Providence, including beliefs that methadone is detrimental to health and that people should attempt to discontinue methadone treatment. Additional potential obstacles to entering methadone therapy include cost and the difficulty of regularly attending a methadone clinic as well as the belief that an individual on MMT is not abstinent from drugs. Substance use researchers and treatment professionals should engage minority communities, particularly Latino communities, in order to better understand the treatment needs of a diverse population, develop culturally appropriate MMT programs, and raise awareness of the benefits of MMT.

    Objective The need for expansion of health services provided in drug treatment programs has been widely discussed since the beginning of the HIV epidemic among drug users. Service expansion has focused on various types of services including medical services (e.g., primary care) and harm reduction services (e.g., provision of sterile syringes). Methods A staff survey was conducted in eight methadone maintenance clinics in the New York/New Jersey area to assess attitudes towards the provision of harm reduction and other services in methadone clinics, and the relationship of these attitudes to other variables. Participants A total of 114 staff members in eight methadone maintenance clinics completed the survey. Results The majority of staff was supportive of adding services, over 90% supported medical services, and the majority supported harm reduction services such as syringe access and disposal services. Higher education and HIV knowledge levels were significant correlates of favorable attitudes toward service provision. Conclusion Support for providing harm reduction services in methadone maintenance clinics was found. Enhancing knowledge of staff regarding various types of health services, and engaging them in how best to institute new services, should be undertaken when new services are planned. PMID:22107879

    Heroin dependence is a major health and social problem associated with increased morbidity and mortality that adversely affects social circumstances, productivity, and healthcare and law enforcement costs. In the UK and many other Western countries, both methadone and buprenorphine are recommended by the relevant agencies for detoxification from heroin and for opioid maintenance therapy. However, despite obvious benefits due to its unique pharmacotherapy (eg, greatly reduced risk of overdose), buprenorphine has largely failed to overtake methadone in managing opioid addiction. The experience from the developing world (based on data from India) is similar. In this article we compare the advantages and disadvantages of the use methadone and buprenorphine for the treatment of opioid addiction from both a developed and developing world perspective; and explore some of the reasons why buprenorphine has not fulfilled the expectations predicted by many in the addictions field.

    Objectives: To study neonatal outcomes following buprenorphine/naloxone and methadone exposure during pregnancy. Methods: This study is a retrospective review of clinical and demographic information of 58 infants whose mothers were treated with buprenorphine/naloxone and 92 infants whose mothers were treated with methadone for opioid dependence during pregnancy. Results: Gestational age, birth weight, prematurity, admission to neonatal intensive care unit, and length of stay were similar between both groups of infants. Neonatal abstinence syndrome occurred less frequently among infants of mothers treated with buprenorphine/naloxone than those treated with methadone (64% and 80%, respectively, p = 0.03). All infants with neonatal abstinence syndrome were treated postnatally with methadone. There was a trend toward shorter duration of treatment and lower cumulative dosages of methadone among the buprenorphine/naloxone–exposed infants. Conclusions: No apparent significant adverse neonatal outcomes were detected following treatment with either maintenance medication; however, further prospective research is necessary to examine the safety and efficacy of buprenorphine/naloxone in pregnancy and its effects on the neonate.

    Specific deuterium labeling of methadone and use of gas chromatography-mass spectroscopy technique permits rapid and quanitative determination of the ratio of the labeled to unlabeled drug in body fluids. A trideuertiomethadone (methadone-d3) was shown to have exactly the same analgesic activity and toxicity in mice as methadone. The rates of absorption, distribution, and excretion of methadone-d3 and methadone were identical in rats. These observations suggest that methadone-d3 may be used as an in vivo marker for monitoring methadone intake of patients, and thus may improve the effectiveness of methadone treatment programs.

    There is a manifest lack of psychometrically sound instruments designed for specific and multidimensional assessment of satisfaction with methadone as a medication within the context of methadone maintenance treatment. Therefore, it may be worthwhile to assess the pertinence and utility of using a generic and multidimensional medication satisfaction instrument that has not been specifically developed for use in methadone maintenance treatment.The aim of this study was thus to explore the psychometric properties of the Spanish version of the Treatment Satisfaction Questionnaire for Medication (TSQM version 1.4 [Health Qual Life Outcomes. 2004;2:12]) in a sample of methadone-maintained heroin-dependent patients.Two hundred three methadone-maintained patients filled out the TSQM and other several measures related to the construct of patient satisfaction (eg, Verona Service Satisfaction Scale for methadone treatment). Dimensionality of the TSQM was assessed by means of a confirmatory factor analysis. Internal consistency was examined using the ordinal coefficient α. Spearman correlations were used to explore the relationship between the TSQM and the measures conceptually related to patient satisfaction.Regarding the dimensionality of the TSQM, its original factor structure adequately fitted the data (Satorra-Bentler χ58, 72.14 [P = 0.100]; root-mean-square error of approximation, 0.045; comparative fit index, 0.978). All but 1 of the 4 TSQM subscales showed acceptable to good internal consistency values (0.78-0.89). The dimensions of the TSQM were differentially and congruently correlated with related measures.The results strongly suggest the TSQM value as a brief, generic, and psychometrically sound instrument to assess satisfaction with methadone as a medication in a multidimensional manner. Notwithstanding, more research is needed not only to assess the generalizability of these findings but also to provide pieces of evidence for other psychometric properties

    This trial was aimed to estimate the pharmacokinetic interaction between voriconazole and methadone at steady state in male patients on methadone therapy and to characterize the safety and tolerability profile during the coadministration. Twenty-three patients on individualized methadone therapy (30 to 100 mg once daily) were enrolled into this randomized, patient- and investigator-blind, placebo-controlled, parallel-group study. Methadone pharmacokinetic samples were collected from patients receiving methadone alone as the baseline before they were randomized to coadminister either 200 mg voriconazole twice daily (BID) (400-mg BID loading doses on the first day) (n = 16) or matching placebo (n = 7) for the next 5 days. Pharmacokinetic samples for methadone and voriconazole were collected on the last day of voriconazole dosing. The safety data were collected throughout the study. Voriconazole increased the steady-state exposure of pharmacologically active enantiomer (R)-methadone: the mean area under the concentration-time curve from 0 to 24 h (AUC0-24) was increased by 47.2% (90% confidence intervals [CI]: 37.7%, 57.4%), and the mean peak concentration (Cmax) was increased by 30.7% (90% CI: 22.2%, 39.8%). The magnitude of increase in (S)-methadone exposure was greater than that of (R)-methadone: the AUC0-24 was increased by 103.4% (90% CI: 85.0%, 123.6%), and the Cmax was increased by 65.4% (90% CI: 52.6%, 79.2%). Methadone appeared to have no effect on the steady-state voriconazole pharmacokinetics compared to the historical data for voriconazole alone. Methadone patients receiving voriconazole showed no signs or symptoms of significant opioid withdrawal or overdose. Coadministration of 200 mg voriconazole BID with methadone was generally safe and well tolerated. Nevertheless, caution should be exercised when voriconazole is coadministered with methadone due to the increase in (R)-methadone exposure, which in turn may require a dose reduction of methadone.

    This cross-sectional study (n = 190) examined correlates of hospitalization for physical health problems among methadone maintenance therapy (MMT) clients with a history of alcohol abuse. The study was derived from baseline data collected for a longitudinal trial assessing the effect of motivational interviewing among alcohol-abusing adults undergoing MMT. The sample included clients who were 18–55 years of age, abusing alcohol, and receiving MMT from five large methadone maintenance clinics in the Los Angeles area. A structured questionnaire was used to collect the data. Correlates of hospitalization in logistic regression analysis included lack of social support, recent victimization, age of first alcohol use, chronic severe pain in the previous six months, not having children, and ethnicity. Identification of hospitalization risk factors among alcohol-abusing MMT clients is a first step to developing risk-reducing interventions designed to lower hospitalization rates in this population.

    Background To expand its public-sector treatment capacity, Baltimore City made buprenorphine treatment accessible to low-income, largely African American residents. This study compares the characteristics of patients entering methadone treatment v. buprenorphine treatment to determine whether BT was attracting different types of patients. Methods Participants consisted of two samples of adult heroin-dependent African Americans. The first sample was newly-admitted to a health center or a mental health center providing buprenorphine (N=200), and the second sample was newly-admitted to one of two hospital-based methadone programs (N=178). The Addiction Severity Index (ASI) and the Friends Supplemental Questionnaire were administered at treatment entry and data were analyzed with logistic regression. Results BT participants were more likely to be female (p=.017) and less likely to inject (p=.001). Participants with only prior buprenorphine treatment experience were nearly five time more likely to enter buprenorphine than methadone treatment (p<.001). Those with experience with both treatments were more than twice as likely to enter BT (OR=2.7, 95% CI=1.11–6.62; p=.028). In the 30 days prior to treatment entry, BT participants reported more days of medical problems (p=.002) and depression (p=.044), and were more likely to endorse a lifetime history of depression (p<.001). Conclusion Methadone and buprenorphine treatment provided in the public sector may attract different patient subpopulations. Providing buprenorphine treatment through drug treatment programs co-located with a health and mental health center may have accounted for their higher rates of medical and psychiatric problems and appears to be useful in attracting a diverse group of patients into public-sector funded treatment.

    Effective treatment for patients with opioid use problems is as critical as ever given the upsurge in heroin and prescription opioid abuse. Yet, results from prior studies show that the majority of methadone maintenance treatment (MMT) programs in the US have not provided dose levels that meet evidence-based standards. Thus, this paper examines the extent to which US MMT programs have made changes in the past 23 years to provide adequate methadone doses; we also identify factors associated with variation in program performance. Program directors and clinical supervisors of nationally-representative methadone treatment programs were surveyed in 1988 (n=172), 1990 (n=140), 1995 (n=116), 2000 (n=150), 2005 (n=146), and 2011 (n=140). Results show that the proportion of patients who received doses below 60 mg/day-the minimum recommended-declined from 79.5 to 22.8% in a 23-year span. Results from random effects models show that programs that serve a higher proportion of African-American or Hispanic patients were more likely to report low-dose care. Programs with Joint Commission accreditation were more likely to provide higher doses, as were a program that serves a higher proportion of unemployed and older patients. Efforts to improve methadone treatment practices have made substantial progress, but 23% of patients across the nation are still receiving doses that are too low to be effective. PMID:25012549

    Although buprenorphine is used worldwide as a safe and effective maintenance medication for opioid dependence, some countries have reported a growing incidence of abuse of this medication. Buprenorphine is considered to have lower abuse potential because of its partial agonist profile, but no studies have directly compared the reinforcing effects of buprenorphine with those of full mu opioid agonists in humans. The present double-blind, placebo-controlled inpatient study compared the reinforcing and subjective effects of intravenously administered buprenorphine (0.5, 2, and 8 mg) and methadone (5, 10, and 20 mg). Participants (n = 6) were detoxified from heroin during the first 1 to 2 weeks after admission. During subsequent weeks, participants received a sample drug dose and $20 on Monday, and they could self-administer either the sampled dose or $20 during one choice session per day on Thursday and Friday. Participants responded under a modified progressive ratio schedule during each choice session. All active doses maintained higher progressive ratio break points (largest completed ratio) than placebo. There were no significant differences in break point values between buprenorphine and methadone or among the different doses of drug. However, several subjective ratings, including "good drug effect", "high", and "liking" dose-dependently increased after administration of buprenorphine and methadone. The peak ratings for these effects did not significantly differ for the two drugs. These results demonstrate that under these experimental conditions, buprenorphine and methadone were equally effective in producing reinforcing and subjective effects. PMID:16144974

    To identify factors contributing to methadone-related deaths in Ontario in 2004, demographic factors, methadone blood levels, evidence of concurrent drug use, the source of methadone (prescribed or illicit), and its contribution in exacerbating preexistent disease were studied to identify users at risk for methadone toxicity and death. This retrospective study reviewed postmortem data, autopsy reports, police reports, hospital data, and postmortem toxicological analyses available in the Ontario Chief Coroner's Information System. There were 54 cases with methadone detected in postmortem blood samples. Of total, 9 cases were not included in the study because of incomplete documentation. About 11 deaths were due to methadone toxicity alone; 25 deaths were due to combined methadone and other drug toxicity (notably cocaine and alcohol); 7 deaths were due to the exacerbation of a preexisting disease by methadone; 1 death was due to disease alone, and 1 death was due to trauma sustained in a motor vehicle collision. A significant number of methadone-related deaths were due to illicit methadone ingestion, which exceeded the opioid tolerance level. The source of methadone in these cases was unknown. Drug addicts, unaware of the hazard of consuming other illicit or prescription drugs concurrently, are at risk. This study demonstrated that methadone toxicity is enhanced by underlying disease, especially in individuals with underlying cardiac and pulmonary pathology. PMID:20081524

    1. By use of a sensitive and specific fluorescence assay procedure it was shown that after subcutaneous administration to rats, (+/-)-methadone was concentrated in the lung. Lung to serum ratios ranging from 25 to 60 were obtained indicating that the rat lung tissue was capable of extracting (+/-)-methadone against a concentration gradient. 2. This phenomenon was investigated in vitro with rat lung slices incubated in Krebs-Ringer phosphate buffer (pH 7.4). The uptake was expressed in terms of tissue to medium concentration ratios (T/M ratio). 3. The principal observations were: (i) Studies on the time-course of the uptake showed that the T/M ratios of (+/-)-methadone increased rapidly during the first 60 min of incubation and then more slowly, with a plateau occurring at 180 min; (ii) The T/M ratio of (+/-)-methadone progressively increased from 9.5 to 17 as the pH of the incubation medium was varied from 6.2 to 7.5; (iii) When the concentration of (+/-)-methadone in the incubation medium was varied from 0.005 to 0.5 mM, the T/M ratio decreased rapidly suggesting self-saturation of the transport process. Beyond the medium concentration of 0.5 mM, the T/M ratio declined very slowly. 4. These results suggested that at low concentrations, (+/-)-methadone was transported predominantly by a self-saturable process while at higher concentrations it was transported by a process of simple diffusion. 5. At low concentrations (0.01 mM) the uptake of (+)-methadone was higher than that of (-)-isomer indicating stereo-specificity of the uptake process. The uptake of (+/-)-methadone at low concentration (0.01 mM) was significantly inhibited by low temperature, lack of O2, lack of glucose, lack of Na+ in the incubation medium, and by exposure of the tissue to high temperature (approximately 100 degrees C). The uptake was also inhibited by relatively high concentration of iodoacetate (1.0 mM) and of naloxone (1.0 mM). 6. Kinetic analysis of data showed that the diffusion constant

    The substance methadone is used for substitution therapy since the 1960s in the U.S. Mainly because of the endemic spread of HIV-1 infections among intravenous drug abusers methadone was made legally available through medical prescription in Austria in 1987. Legal authorities today also allow the patient to take home the necessary daily consumption for weekends or public holidays. The drug is distributed as a watery solution in tiny bottles, which are fitted with an ordinary screw cap. This kind of distribution may, however, have fatal consequences. This is demonstrated in the following case of accidental poisoning of an infant: A two-year-old girl whose parents were both participating in the substitution scheme was found dead in her bed in Vienna in 1997. Forensic autopsy revealed a methadone concentration in the liver tissue of 640 ng/g. The criminal investigation determined that the girl had opened a bottle of methadone solution and subsequently had taken the drug. Considering the circumstances of this accident, from the medical point of view safety devices for the screw caps of the methadone bottles should be required by law, in order to avoid future accidental poisoning.

    Background: Client characteristics provide useful information for designing programs that target individuals with risk factors for substance use and for determining client retention. Therefore, this study examined the profiles of clients attending a methadone clinic. Methods: A cross-sectional analysis of clients of a methadone clinic was conducted through a survey to obtain a profile of methadone clients. Results: Of the 51 patients who responded (response rate: 66.2%), the mean (SD) age at which they started substance use was 19.8 (5.1) years. Friends were cited as the most regular source of drugs (82.4%), and heroin was the most commonly used drug (98%). Daily substance use was reported by 72.5% of the respondents; 23.5% admitted to having stolen money to purchase drugs; 92.2% tried quitting substance use on their own and 98% stated that the main reason for registering at the clinic was that they wanted to stop their drug dependence. Approximately 60% of clients were receiving methadone doses of less than 60 mg/day. Conclusion: Heroin is still the most popular drug of abuse and most clients still receive methadone doses below the recommended level, despite evidence of poor patient retention rates associated with these low doses.

    Aims To test the efficacy and safety of varenicline as an aid to smoking cessation in methadone maintained smokers. Design Multicenter, randomized, double-blind, placebo-controlled trial with random assignment to 12 weeks of varenicline 1 mg twice daily (n=57) or matched placebo (n=55), with in-person and telephone counseling. Setting Urban methadone programmes in the Bronx, New York City, New York, USA. Participants: Methadone maintenance patients, smoking ≥5 cigarettes/day, interested in quitting, stable in methadone treatment, without current axis I psychiatric disorders, suicidal ideation, or recent suicide attempts. Measurements Seven-day point prevalence abstinence verified by expired carbon monoxide (CO) < 8 p.p.m at week 12 (primary outcome); CO-verified abstinence, cigarettes/day, incident axis I psychiatric illness, suicidal ideation or serious adverse events (SAEs) at weeks 2, 4, 8, 12 or 24 (secondary outcomes). Findings Baseline demographic, smoking and clinical factors were similar between groups. Retention at 24 weeks was 90%. Subjects receiving varenicline were more likely than those receiving placebo to achieve abstinence (10.5% v 0%, p = .03; effect size 10.5%, 95% CI 4.4 – 19.3%) and to reduce smoking (median 5 v 2 cigarettes/day, p<.001) at 12 weeks. These effects were not maintained after drug treatment ceased. Incident psychiatric illness (OR = 0.84, 95% CI 0.16, 4.4) and suicidality (OR = 0.88, 95% CI 0.2, 3.9) were not different between groups. There were no psychiatric or cardiac SAEs. Conclusions Varenicline can aid short-term smoking abstinence in methadone maintained smokers. PMID:24862167

    Background: Methadone is associated with a statistically significant increase in BMI in the first 2 years of treatment. Objectives: To evaluate the changes of body composition (bone mass, % fat, % muscle mass, % water, and basal metabolic rate) related to this increase. Patients and Methods: Changes in body composition were monitored, via bioelectrical impedance, in 29 patients in methadone treatment for opiate dependency (age 18 to 44, mean = 29.3, SD = 7.0, 13 men, 16 women). Results: Within one year from admission to treatment, a statistically significant (t-tests, P < 0.05) increase was noted in their body mass index (BMI), % of body fat, average body mass, and average basal metabolic rate, and relative decrease in their % of muscle mass and % of bone mass. Neither absolute bone mass nor muscle mass changed significantly. Conclusions: Physicians involved in care of methadone patients should recommend dietary and lifestyle changes to improve their overall health. PMID:27162765

    Hepatitis C virus (HCV) infection is common among people who inject drugs, including those managed with maintenance opioids. Pharmacokinetic interactions between opioids and emerging oral HCV antivirals merit evaluation. Daclatasvir is a potent pangenotypic inhibitor of the HCV NS5A replication complex recently approved for HCV treatment in Europe and Japan in combination with other antivirals. The effect of steady-state daclatasvir (60 mg daily) on stable plasma exposure to oral opioids was assessed in non-HCV-infected subjects receiving methadone (40 to 120 mg; n = 14) or buprenorphine plus naloxone (8 to 24 mg plus 2 to 6 mg; n = 11). No relevant interaction was inferred if the 90% confidence interval (CI) of the geometric mean ratio (GMR) of opioid area under the plasma concentration-time curve over the dosing interval (AUCτ) or maximum concentration in plasma (Cmax) with versus without daclatasvir was within literature-derived ranges of 0.7 to 1.43 (R- and S-methadone) or 0.5 to 2.0 (buprenorphine and norbuprenorphine). Dose-normalized AUCτ for R-methadone (GMR, 1.08; 90% CI, 0.94 to 1.24), S-methadone (1.13; 0.99 to 1.30), and buprenorphine (GMR, 1.37; 90% CI, 1.24 to 1.52) were within the no-effect range. The norbuprenorphine AUCτ was slightly elevated in the primary analysis (GMR, 1.62; 90% CI, 1.30 to 2.02) but within the no-effect range in a supplementary analysis of all evaluable subjects. Dose-normalized Cmax for both methadone enantiomers, buprenorphine and norbuprenorphine, were within the no-effect range. Standardized assessments of opioid pharmacodynamics were unchanged throughout daclatasvir administration with methadone or buprenorphine. Daclatasvir pharmacokinetics were similar to historical data. Coadministration of daclatasvir and opioids was generally well tolerated. In conclusion, these data suggest that daclatasvir can be administered with buprenorphine or methadone without dose adjustments. PMID:26124175

Four hundred forty participants were randomly assigned to either a control or a motivationally-enhanced viral hepatitis education and counseling intervention. Viral hepatitis A (HAV), B (HBV), and C (HCV) knowledge tests were administered at baseline, following each of two education sessions (post-education), and at a 3-month follow-up assessment. Results indicated a significant increase in knowledge of HAV, HBV, and HCV over time. No differences were found in knowledge between the intervention groups in knowledge acquisition regarding any of the hepatitis viruses suggesting that a motivational interviewing style may not augment hepatitis knowledge beyond standard counseling. A two-session viral hepatitis education intervention effectively promotes hepatitis knowledge and can be integrated in methadone treatment settings. PMID:24462241

    Objectives To explore methadone and 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) umbilical cord disposition, correlate with maternal methadone dose and neonatal outcomes, and evaluate the window of drug detection in umbilical cord of in utero illicit drug exposure. Methods Subjects, 19 opioid-dependent pregnant women from two clinical studies, one comparing methadone and buprenorphine pharmacotherapy for opioid-dependence treatment, and the second examining monetary reinforcement schedules to maintain drug abstinence. Correlations were calculated for methadone and EDDP umbilical cord concentrations and maternal methadone dose, and neonatal outcomes. Cocaine- and opiate-positive umbilical cord concentrations were compared to those in placenta and meconium, and urine specimens collected throughout gestation. Results Significant positive correlations were found for umbilical cord methadone concentrations and methadone mean daily dose, mean dose during the 3rd trimester and methadone cumulative daily dose. Umbilical cord EDDP concentrations and EDDP/methadone concentration ratios were positively correlated to newborn length, peak neonatal abstinence syndrome (NAS) score and time-to-peak NAS score. Methadone concentrations and EDDP/methadone ratios in umbilical cord and placenta were positively correlated. Meconium identified many more cocaine and opiate positive specimens than umbilical cord. Conclusion Umbilical cord methadone concentrations were correlated to methadone doses. Also, our results indicate that methadone and EDDP concentrations might help to predict NAS severity. Meconium proved to be more suitable than umbilical cord to detect in utero exposure to cocaine and opiates; however, umbilical cord could be useful when meconium is unavailable due to in utero or delayed expulsion.

    The aim of this study was to switch patients established on methadone opioid substitution therapy (OST) to morphine over 1 week. Subjects established on daily methadone OST (mean dose 60 mg/day) were switched to morphine slow-release capsules, dosed at 4× the previous total daily methadone dose, for 6 days, then given morphine syrup dosed q3h. All 27 subjects enrolled in this study completed the switch from methadone to morphine. Opioid withdrawal symptoms (OWS) peaked within 12-24 hours of starting morphine, and 24/27 subjects required higher daily morphine doses (mean 5.2× multiple). Pharmacokinetic evaluation showed that 91% of methadone was cleared during this time, with a mean elimination half-life of 59 hours. The most frequent treatment-emergent non-OWS adverse events were headache, nausea, constipation, and neck pain. The method described here appears to be a safe and acceptable approach to switch subjects from methadone to morphine. PMID:26763764

    This study assessed the reliability, validity, discriminative accuracy, and factor structure of the Detoxification Fear Survey Schedule (DFSS). Prevalence of detoxification fear and its correlates also were assessed. Random samples from three geographically, culturally, and racially disparate populations (N = 271) of treated opioid addicts were used. The DFSS had a test-retest r = .935 and demonstrated several indicants of validity. A briefer version (DFSS-14) showed superior psychometric properties and could identify correctly 81% of the detox fear subjects while it excluded 55% of nonfear subjects. The DFSS-14 had a replicated three-factor structure that accounted for 62.1% of total item variance in the validation sample. Factor two, probably best named dose reduction fear, was replicated in all populations. A cut-off score set at the nonfear mean is recommended for clinical use. A brief clinical interview of positive scorers quickly should eliminate false positives and, thus, efficiently identify most of those with detoxification fear. PMID:3667947

    Prevalence of prescription opioid abuse has increased dramatically in recent years in the United States generally, and a similar pattern of increasing prescription opioid use has also been noted among patients seeking treatment for opioid dependence. This study presents results from an internal quality assurance project conducted by an outpatient methadone maintenance (MM) treatment clinic which sought to examine the extent of ongoing oxycodone abuse among patients that might be going undetected with current urinalysis-testing methods. One hundred five MM patients provided 437 urine samples over a 6-week period. Samples were analyzed using the clinic's usual enzyme multiplied immunoassay test (EMIT) opiate assay (300 ng/ml opiate cutpoint) and a supplemental oxycodone test strip (100 ng/ml oxycodone cutpoint). The EMIT assay identified only 6% (20/437) of samples as positive for oxycodone, whereas the oxycodone test strip indicated that 19% (83/437) tested positive for recent oxycodone use. Inspection of patient characteristics revealed that oxycodone users were more likely to report a prescription opioid as their primary drug at intake, be in MM treatment for a significantly shorter duration, and provide significantly more opioid- and cocaine-positive urine samples. Overall, these data illustrate the potential importance of monitoring for ongoing oxycodone use in MM clinics. Although future efforts should examine this question using more rigorous experimental methods, findings from this initial project have implications for clinical issues such as evaluating patient stability in treatment, making medication-dosing decisions, and determining patient eligibility for methadone take-home privileges.

    Acute renal failure from rhabdomyolysis is a well-established clinical entity; however, rhabdomyolysis exclusively caused by the ingestion of methadone requiring hemodialysis is very uncommon. With a similar mechanism to opiates, methadone can cause rhabdomyolysis and further consequences. Given the increasing use of methadone as a therapy for opiate dependence, clinicians prescribing this medication should be aware of this life-threatening complication. PMID:25782567

    Methadone is largely used for the substitution management of opiate-dependent individuals but can also be easily found on the black market. The first cases involving repetitive sedation linked to the use of methadone and subsequent death of 2 babies are reported. At the autopsy, no particular morphologic changes were noted except for pulmonary and visceral congestion. There was no evidence of violence, and the pathologist in both cases found no needle marks. Toxicological analyses, as achieved by GC/MS, demonstrated both recent and repetitive methadone exposure. In case 1, a 14-month-old girl was found dead at home. Blood concentrations were 1071 and 148 ng/mL for methadone and EDDP, respectively. Hair (6 cm) tested positive at 1.91 and 0.82 ng/mg for methadone and EDDP, respectively. In case 2, a 5-month-old girl was taken to hospital in a pediatric unit for coma. Antemortem blood analysis demonstrated methadone exposure (142 ng/mL), and the baby was declared dead 12 days after admission. Hair analysis (5 cm) by segmentation was positive for methadone in the range 1.0 (root) to 21.3 ng/mg (end). The death of the babies was attributed to accidental asphyxia ina situation where methadone was considered as a chemical weapon. The mothers, who were the perpetrators in both cases, did not deny the use of methadone as a sedative drug. PMID:16404812

    We surveyed 150 methadone maintenance treatment (MMT) program patients about willingness to use, and perceived efficacy of, conventional and unconventional nonpharmacological stress-related treatments. Although levels of treatment willingness and perceived efficacy for both conventional and unconventional treatments were high, ratings for conventional interventions were, on average, significantly higher than those for unconventional ones. Dimensions of psychiatric distress—but not demographic or MMT characteristics—predicted treatment willingness for conventional therapies and treatment willingness and perceived efficacy for unconventional therapies. These findings are likely to have implications for resource and program planning in MMT programs. PMID:21314756

    Over the past 20 years, specialized programming for chemically dependent women has been recommended for improving psychosocial functioning and retention in treatment. This study examined the impact of a structured, six-week assertiveness and sexuality workshop for women at three community-based methadone maintenance programs. Results indicated that women who participated frequently in the women's groups (four to six sessions) showed greater increases in self-esteem and knowledge compared to women who participated infrequently (one to three sessions). In addition, level of participation was positively associated with length of stay in the treatment program after completing the workshop. PMID:7844654

    Use of the prescription opioid methadone for treatment of pain, as opposed to treatment of opioid use disorder (e.g., addiction), has been identified as a contributor to the U.S. opioid overdose epidemic. Although methadone accounted for only 2% of opioid prescriptions in 2009 (1), it was involved in approximately 30% of overdose deaths. Beginning with 2006 warnings from the Food and Drug Administration (FDA), efforts to reduce methadone use for pain have accelerated (2,3). The Office of the Assistant Secretary for Planning and Evaluation of the U.S. Department of Health and Human Services and CDC analyzed methadone distribution, reports of diversion (the transfer of legally manufactured methadone into illegal markets), and overdose deaths during 2002-2014. On average, the rate of grams of methadone distributed increased 25.1% per year during 2002-2006 and declined 3.2% per year during 2006-2013. Methadone-involved overdose deaths increased 22.1% per year during 2002-2006 and then declined 6.5% per year during 2006-2014. During 2002-2006, rates of methadone diversion increased 24.3% per year; during 2006-2009, the rate increased at a slower rate, and after 2009, the rate declined 12.8% per year through 2014. Across sex, most age groups, racial/ethnic populations, and U.S. Census regions, the methadone overdose death rate peaked during 2005-2007 and declined in subsequent years. There was no change among persons aged ≥65 years, and among persons aged 55-64 years the methadone overdose death rate continued to increase through 2014. Additional clinical and public health policy changes are needed to reduce harm associated with methadone use for pain, especially among persons aged ≥55 years. PMID:27387857

    Aims Methadone is standard pharmacotherapy for opioid-dependent pregnant women, yet the relationship between maternal methadone dose and neonatal abstinence syndrome (NAS) severity is still unclear. This research evaluated whether quantification of fetal methadone and drug exposure via meconium would reflect maternal dose and predict neonatal outcomes. Design Prospective clinical study Setting An urban drug treatment facility treating pregnant and post-partum women and their children Participants Forty-nine opioid-dependent pregnant women received 30–110 mg methadone daily. Measurements Maternal methadone dose, infant birth parameters and NAS assessments were extracted from medical records. Thrice-weekly urine specimens were screened for opioids and cocaine. Newborn meconium specimens were quantified for methadone, opioid, cocaine and tobacco biomarkers. Findings There was no relationship between meconium methadone concentrations, presence of opioids, cocaine and/or tobacco in meconium, maternal methadone dose or NAS severity. Opioid, cocaine and tobacco biomarkers also were found in 36.7, 38.7 and 81.1% of meconium specimens, respectively, and were associated with positive urine specimens in the third trimester. The presence of opioids other than methadone in meconium correlated with increased rates of preterm birth, longer infant hospital stays and decreased maternal time in drug treatment. Conclusions Methadone and its metabolite 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) concentrations in meconium did not predict infant birth parameters or NAS severity. Prospective urine testing defined meconium drug detection windows for opiates and cocaine as three months, rather than the currently accepted six months. The presence of opioids in meconium could be used as a biomarker for infants at elevated risk in the newborn period. PMID:20854338

    The effects of methadone maintenance treatment (MMT) on neurophysiological function are unclear. Using an auditory oddball paradigm, event-related potential (ERP) amplitudes and latencies were measured in 32 patients undertaking MMT, 17 opiate users who were addicted but not receiving substitution treatment and 25 healthy control subjects. Compared with healthy control subjects, the MMT and opiate user groups showed an increased P200 amplitude in response to target stimuli. The opiate user group also exhibited a decreased amplitude and an increased latency of N200, and a greater number of task-related errors than either healthy control subjects or patients undertaking MMT. There were no significant group differences in the P300 amplitude. However, it is noteworthy that the frontal P300 amplitude of the MMT group was greater than that of opiate users or healthy controls. Our findings suggest that altered sensory information processing associated with a history of opiate use remains in patients undertaking MMT. However, there are less marked ERP abnormalities in those receiving MMT than in active opiate users. The deficits in information processing associated with illicit opiate use are likely to be reduced during MMT. PMID:26038111

    Methadone is one of the most popular synthetic opioids in the world with some favorable properties making it useful both in the treatment of moderate to severe pain and for opioid addiction. Increased use of methadone has resulted in an increased prevalence of its toxicity, one aspect of which is cardiotoxicity. In this paper, we review the effects of methadone on the heart as well as cardiac concerns in some special situations such as pregnancy and childhood. Methods: We searched for the terms methadone, toxicity, poisoning, cardiotoxicity, heart, dysrhythmia, arrhythmia, QT interval prolongation, torsade de pointes, and Electrocardiogram (ECG) in bibliographical databases including TUMS digital library, PubMed, Scopus, and Google Scholar. This review includes relevant articles published between 2000 and 2013. The main cardiac effects of methadone include prolongation of QT interval and torsade de pointes. Other effects include changes in QT dispersion, pathological U waves, Taku-Tsubo syndrome (stress cardiomyopathy), Brugada-like syndrome, and coronary artery diseases. The aim of this paper is to inform physicians and health care staff about these adverse effects. Effectiveness of methadone in the treatment of pain and addiction should be weighed against these adverse effects and physicians should consider the ways to lessen such undesirable effects. This article presents some recommendations to prevent heart toxicity in methadone users. PMID:26869865

    Several studies reported high rates of psychiatric commorbidity among methadone patients. We examined the relationships of measures of psychopathology to outcomes of screening urine tests for cocaine, opiates, and benzodiazepines in a sample of 56 methadone patients. They also completed the Symptom Check List-90-Revised (SCL-90-R). The highest scales in the SCL-90-R profile of our patients were those indicating somatic discomfort, anger, phobic anxiety, paranoid ideation, and also obsessive-compulsive disorder symptoms (scores above the 39th percentile). The only significant correlations between urine tests and SCL-90-R psychopathology were those involving benzodiazepines: patients with urine tests positive for benzodiazepines had lower social self-confidence (r=0.48), were more obsessive-compulsive (r=0.44), reported a higher level of anger (r=0.41), of phobic tendencies (r=40), of anxiety (r=0.39), and of paranoid tendencies (r=0.38), and also reported more frequent psychotic symptoms (r=0.43).

On questioning it was discovered that the patient was receiving 50 mg of intramuscular methadone daily, in the community. She was a former intravenous drug user who had been enrolled into a methadone substitution programme for 10 years and had been receiving her methadone intramuscularly for the past 6 years. It had been discovered that her addiction was not solely to opioids but, moreover, to the process of injecting as well. She was diagnosed with obsessive compulsive disorder, with a needle fixation, and started on the intramuscular methadone regimen on which she has maintained abstinence from heroin for 6 years.

    Among agents for treatment of opioid addiction, methadone is a full mu-opioid receptor agonist, whereas buprenorphine is a partial agonist. Both are long-acting. Buprenorphine has a superior safety profile. Methadone is formulated for oral administration and buprenorphine for sublingual administration. A subdermal buprenorphine implant with a 6-month duration of action is being considered for approval by the U.S. Food and Drug Administration. Both medications reduce mortality rates and improve other outcomes. Data from a recent randomized controlled comparison of both medications (N = 1269) show better treatment retention with methadone but reduced illicit opioid use early in treatment with buprenorphine. Human immunodeficiency virus (HIV) risk behaviors were measured using the Risk Behavior Survey at baseline, 12 weeks, and 24 weeks for study completers. In the 30 days prior to treatment entry, 14.4% of the completers randomized to treatment with buprenorphine (n = 340) and 14.1% of the completers randomized to methadone treatment (n = 391) shared needles. The percent sharing needles decreased to 2.4% for buprenorphine and 4.8 for methadone in the 30 days prior to Week 24 (p < 0.0001). In the 30 days prior to treatment entry, 6.8% of the completers randomized to buprenorphine and 8.2% of the completers randomized to methadone had multiple sexual partners, with only 5.2% and 5.1%, respectively, reporting multiple partners at Week 24 (p < 0.04).

    Employment enhances the outcomes of substance dependency treatment. Unfortunately, although unemployed methadone treatment patients frequently state they are interested in a job, many fail to participate in vocational services when available. Unless patients become engaged, vocational services do not have an opportunity to be effective. This is the first study to explore a broad array of factors that may be associated with differential engagement in vocational services among methadone patients. The study was conducted in two methadone programs in New York City during 2001-2004. Unemployed methadone patients (n = 211) were voluntarily randomly assigned to either of two vocational counseling programs (standard vs. experimental) and followed for 6 months. The sample was 59% male, 75% minority group, aged 45 years on average, and in methadone treatment for 5 years on average. Being engaged in the vocational counseling programs was defined as five or more sessions with the counselor in the first 6 months after study entry. In multivariate analysis, the factors associated with higher engagement in vocational counseling were being non-Hispanic, having more education, a drug injection history, a crack use history, having chronic emotional/mental problems, better work attitudes, and assignment to the experimental vocational program. The results indicate that it is often the most "needy" unemployed methadone patients who become more engaged in vocational counseling. A vocational counseling model which emphasizes assertive outreach and attends to nonvocational clinical issues as well is more likely to engage patients. PMID:16798680

    The focus of drug policy in the UK has shifted markedly in the past 5 years to move beyond merely emphasising drug abstinence towards maximising individuals' opportunities for recovery. The UK government continues to recognise the prescribing of narcotic medications indicated for opiate dependence as a key element of these individuals' recovery journey. This article describes a small, naturalistic comparison of the efficacy of the two most commonly prescribed opiate substitute medications in the UK--methadone hydrochloride (methadone oral solution) and Suboxone (buprenorphine-naloxone sublingual tablets)--for reducing current heroin users' (n = 34) days of heroin use, and preventing short-term abstainers (n = 37) from relapsing to regular heroin use. All patients had been prescribed either methadone or Suboxone for maintenance for 6 months prior to intake. Results showed that when controlling for a number of patient-level covariates, both methadone and Suboxone significantly reduced current users' days of heroin use between the 90 days prior to intake and at the 8-month follow-up, with Suboxone yielding a significantly larger magnitude reduction in heroin use days than methadone. Methadone and Suboxone were highly and equally effective for preventing relapse to regular heroin use, with all but 3 of 37 (91.9%) patients who were abstinent at intake reporting past 90-day point prevalence heroin abstinence at the 8-month follow-up. Overall, prescribing methadone or Suboxone for eight continuous months was highly effective for initiating abstinence from heroin use, and for converting short-term abstinence to long-term abstinence. However, the study design, which was based on a relatively small sample size and was not able randomise patients to medication and so could not control for the effects of potential prognostic factors inherent within each patient group, means that these conclusions can only be made tentatively. These positive but preliminary indications of the

Subjects continued receiving a stable oral dose of either methadone (up to a maximum dose of 180 mg per day) or buprenorphine-naloxone (up to a maximum dose of 24 mg-6 mg per day) and also received oral faldaprevir (240 mg) once daily (QD) for 8 days following a 480-mg loading dose. Serial blood samples were taken for pharmacokinetic analysis. The pharmacodynamics of the opioid maintenance regimens were evaluated by the objective and subjective opioid withdrawal scales. Coadministration of faldaprevir with methadone or buprenorphine-naloxone resulted in geometric mean ratios for the steady-state area under the concentration-time curve from 0 to 24 h (AUC(0-24,ss)), the steady-state maximum concentration of the drug in plasma (C(max,ss)), and the steady-state concentration of the drug in plasma at 24 h (C(24,ss)) of 0.92 to 1.18 for (R)-methadone, (S)-methadone, buprenorphine, norbuprenorphine, and naloxone, with 90% confidence intervals including, or very close to including, 1.00 (no effect), suggesting a limited overall effect of faldaprevir. Although individual data showed moderate variability in the exposures between subjects and treatments, there was no evidence of symptoms of opiate overdose or withdrawal either during the coadministration of faldaprevir with methadone or buprenorphine-naloxone or after faldaprevir dosing was stopped. Similar faldaprevir exposures were observed in the methadone- and buprenorphine-naloxone-treated subjects. In conclusion, faldaprevir at 240 mg QD can be coadministered with methadone or buprenorphine-naloxone without dose adjustment, although given the relatively narrow therapeutic windows of these agents, monitoring for opiate overdose and withdrawal may still be appropriate.

    Background Prior research has demonstrated neuropsychological (NP) impairment in persons with histories of injection drug use (IDU), hepatitis C virus (HCV) infection, and methadone maintenance treatment (MMT), individually, but little is known about the NP effects of these three risk factors in combination. This issue is particularly important in China, which is addressing its highly HCV-comorbid IDU epidemic with widespread government sponsored MMT, especially in light of recent evidence suggesting that methadone may be neuroprotective in some circumstances. Methods We administered a comprehensive NP test battery to 195 Chinese heroin IDU individuals taking MMT (IDU+ group), the majority of whom were also HCV+ (87%; n = 169), and compared their NP performance to that of 198 demographically comparable, non-IDU Chinese controls (IDU− group). All participants in both groups tested negative for HIV infection, which is also a common comorbidity in the Chinese IDU population. Results The IDU+ group did not have an increased rate of global NP impairment, or perform significantly worse on any individual NP test measure. Within the IDU+ group, liver disease characteristics and reported details of heroin use were not significantly associated with NP performance. Conclusion Failure to detect NP impairment in IDU+ subjects with or without HCV infection was surprising, particularly considering the previously demonstrated sensitivity of our NP battery to neurocognitive disorders associated with HIV infection in China. One possible explanation, which should be explored in future research, is the potential neuroprotective effect of methadone in the context of HCV infection and/or heroin withdrawal. PMID:24508003

    While regulatory frameworks governing methadone maintenance therapy (MMT) require highly regimented treatment programs that shape treatment outcomes, little research has examined the effects of regulatory changes to these programs on those receiving treatment, and located their experiences within the wider context of social-structural inequities. In British Columbia (BC), Canada, provincial regulations governing MMT have recently been modified, including: replacing the existing methadone formulation with Methadose(®) (pre-mixed and 10 times more concentrated); prohibiting pharmacy delivery of methadone; and, prohibiting pharmacies incentives for methadone dispensation. We undertook this study to examine the impacts of these changes on a structurally vulnerable population enrolled in MMT in Vancouver, BC. Qualitative interviews were conducted with 34 people enrolled in MMT and recruited from two ongoing observational prospective cohort studies comprised of drug-using individuals in the six-month period in 2014 following these regulatory changes. Interview transcripts were analysed thematically, and by drawing on the concept of 'structural vulnerability'. Findings underscore how these regulatory changes disrupted treatment engagement, producing considerable health and social harms. The introduction of Methadose(®) precipitated increased withdrawal symptoms. The discontinuation of pharmacy delivery services led to interruptions in MMT and co-dispensed HIV medications due to constraints stemming from their structural vulnerability (e.g., poverty, homelessness). Meanwhile, the loss of pharmacy incentives limited access to material supports utilized by participants to overcome barriers to MMT, while diminishing their capacity to assert some degree of agency in negotiating dispensation arrangements with pharmacies. Collectively, these changes functioned to compromise MMT engagement and increased structural vulnerability to harm, including re-initiation of injection drug

    Long-term potentiation (LTP) of monosynaptically evoked field potentials (MEFP) in the dentate gyrus of freely moving rats following tetanization of the perforant pathway was investigated after peripheral application of substances which have been shown to influence NMDA receptor-mediated effects (dextromethorphan, methadone) as well as structurally related substances with similar antitussive effects (codeine, normethadone). The noncompetitive NMDA receptor antagonist MK 801 was also tested for comparison. Whereas under control conditions the field e.p.s.p. (excitatory postsynaptic potential) and the population spike of the MEFP were largely uninfluenced by these substances, different effects were seen after the induction of LTP. MK 801 (0.2 mg/kg i.p.) suppressed the induction of LTP of both the field e.p.s.p. and the population spike. Dextromethorphan (40 mg/kg i.p.) also prevented the potentiation of the field e.p.s.p. and the population spike, thus resembling MK 801 in its effect. Codeine (20 mg/kg i.p.), the levorotatory structural analogue of dextromethorphan had no effect. Methadone and normethadone did not influence the potentiation of the field e.p.s.p. or interfere with the induction of potentiation of the population spike but depressed its maintenance. The results obtained with MK 801 confirm those reported by others. Comparison of the effects of dextromethorphan with those of MK 801, suggests that there is a direct interaction with the NMDA receptor-ionophore complex. The effects of methadone and normethadone appear not to be linked to an interaction with opioid receptors, since naloxone did not influence the suppression of LTP caused by methadone. The possibility of interference with the NMDA receptor-ionophore complex is discussed. PMID:8449228

  16. Methadone treatment providers’ views of drug court policy and practice: a case study of New York State

    PubMed Central

    2013-01-01

    Background Specialized drug treatment courts are a central part of drug-related policy and programs in the United States and increasingly outside the U.S. While in theory they offer treatment as a humane and pragmatic alternative to arrest and incarceration for certain categories of drug offenses, they may exclude some forms of treatment–notably methadone maintenance treatment (MMT). We sought to understand from the perspective of treatment providers whether this exclusion existed and was of public health importance in New York State as a case example of a state heavily committed to drug courts and with varying court-level policies on MMT. Drug courts have been extensively evaluated but not with respect to exclusion of MMT and not from the perspective of treatment providers. Methods Qualitative structured interviews of 15 providers of MMT and 4 NGO advocates in counties with diverse court policies on MMT, with content analysis. Results Courts in some counties require MMT patients to “taper off” methadone in an arbitrary period or require that methadone be a “bridge to abstinence”. Treatment providers repeatedly noted that methadone treatment is stigmatized and poorly understood by some drug court personnel. Some MMT providers feared court practices were fueling non-medical use of prescription opiates. Conclusions Drug court practices in some jurisdictions are a barrier to access to MMT and may constitute discrimination against persons in need of MMT. These practices should be changed, and drug courts should give high priority to ensuring that treatment decisions are made by or in close consultation with qualified health professionals.

    The aim of this review was to update and summarize the scientific knowledge on the long term outcomes of the different pharmacological treatment options for opioid dependence currently available and to provide a critical discussion on the different treatment options based on these results. We performed a literature search using the PubMed databases and the reference lists of the identified articles. Data from research show that the three pharmacological options reviewed are effective treatments for opioid dependence with positive long term outcomes. However, each one has its specific target population and setting. While methadone and buprenorphine are first line options, heroin-assisted treatment is a second line option for those patients refractory to treatment with methadone with concomitant severe physical, mental, social and/or functional problems. Buprenorphine seems to be the best option for use in primary care offices. The field of opioid dependence treatment is poised to undergo a process of reinforcement and transformation. Further efforts from researchers, clinicians and authorities should be made to turn new pharmacological options into clinical reality and to overcome the structural and functional obstacles that maintenance programmes face in combatting opioid dependence.

    Unmanaged maternal opioid addiction poses health and social risks to both mothers and children in their care. Methadone maintenance treatment (MMT) is a targeted public health service to which nurses and other allied health professionals may refer these high risk families for support. Mothers participating in MMT to manage their addiction and their service providers were interviewed to identify resources to maximize mothers' engagement in treatment and enhance mothers' parenting capacity. Twelve mothers and six service providers were recruited from an outpatient Atlantic Canadian methadone treatment program. Two major barriers to engagement in MMT were identified by both mothers and service providers including (1) the lack of available and consistent childcare while mothers attended outpatient programs and (2) challenges with transportation to the treatment facility. All participants noted the potential benefits of adding supportive resources for the children of mothers involved in MMT and for mothers to learn how to communicate more effectively with their children and rebuild damaged mother-child relationships. The public health benefits of integrating parent-child ancillary supports into MMT for mothers are discussed. PMID:23738065

    Although an increasing number of children are born with prenatal methadone or buprenorphine exposure, little is still known about the potential long-term effects of these opioids. The aim of this study was to investigate executive function (EF) in children of women in opioid maintenance therapy (OMT). A total of 66 children (aged 48-57 months) participated in the study, 35 of which had histories of prenatal methadone or buprenorphine exposure. EF was measured using a battery of neuropsychological tests and the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Results showed that children of women in OMT perform lower on tasks of short-term memory and inhibition compared to nonexposed children, which was mainly associated with lower maternal education and employment rate. The OMT group scored significantly lower on all EF tasks compared to the nonexposed group, although scores fell within the average range on all measures. The development of these children should be monitored to assess for the possible problem behaviors and to promote optimal outcomes. PMID:25354916

    Background: The first methadone maintenance treatment clinic in Tanzania was launched in February 2011 to address an emerging HIV epidemic among people who inject drugs. We conducted a retrospective cohort study to understand factors associated with linkage to HIV care and explore how a methadone maintenance treatment clinic can serve as a platform for integrated HIV care and treatment. Methods: This study used routine programmatic and clinical data on clients enrolled in methadone at Muhimbili National Hospital from February 2011 to January 2013. Multivariable proportional hazards regression model was used to examine time to initial CD4 count. Results: Final analyses included 148 HIV-positive clients, contributing 31.7 person-years. At 30, 60, and 90 days, the probability of CD4 screening was 40% [95% confidence interval (CI): 32% to 48%], 55% (95% CI: 47% to 63%), and 63% (95% CI: 55% to 71%), respectively. Clients receiving high methadone doses (≥85 mg/d) [adjusted hazard ratio (aHR): 1.68, 95% CI: 1.03 to 2.74] had higher likelihood of CD4 screening than those receiving low doses (<85 mg/d). Clients with primary education or lower (aHR: 1.62, 95% CI: 1.05 to 2.51) and self-reported poor health (aHR: 1.96, 95% CI: 1.09 to 3.51) were also more likely to obtain CD4 counts. Clients with criminal arrest history (aHR: 0.56, 95% CI: 0.37 to 0.85]) were less likely to be linked to care. Among 17 antiretroviral therapy eligible clients (CD4 ≤ 200), 12 (71%) initiated treatment, of which 7 (41%) initiated within 90 days. Conclusions: Levels of CD4 screening and antiretroviral therapy initiation were similar to Sub-Saharan programs caring primarily for people who do not inject drugs. Adequate methadone dosing is important in retaining clients to maximize HIV treatment benefits and allow for successful linkage to services. PMID:26009835

  2. Factors associated with HCV risk practices in methadone-maintained patients: the importance of considering the couple in prevention interventions

    PubMed Central

    2014-01-01

    Background One important public health issue associated with opioid use today is the risk of hepatitis C (HCV) infection. Although methadone maintenance may help to decrease HCV-related risk practices, HCV risk behaviors persist and are strongly associated with specific substance use patterns, mental status and social context. The ANRS-Methaville study gave us the opportunity to better disentangle the different relationships between these various factors and HCV risk practices. Methods The ANRS-Methaville multisite randomized trial was designed to assess the feasibility of initiating methadone in primary care by comparing it with methadone initiation in specialized centers. This study recruited 195 participants initiating methadone maintenance and followed up for 12 months. Longitudinal data from this trial was used to acquire a greater understanding of HCV risk practices and their pattern of correlates in this population. We selected 176 patients who had data on HCV risk practices at M0 and M12, accounting for 312 visits. HCV risk practices were defined as follows: sharing needles or syringes, sharing drug paraphernalia, getting a tattoo or having a piercing in a non-professional context, sharing toiletry items. To identify factors associated with HCV risk practices, we performed a mixed logistic regression analysis. Results HCV risk practices were reported by 19% and 15% of participants at baseline and M12, respectively. After adjustment for age, cocaine use and alcohol dependence as well as suicidal risk, living in a couple with a non-drug user and in a couple with a drug user were both independent predictors of HCV risk practices (OR[CI95%] = 4.16 [1.42-12.12]; OR[CI95%] = 9.85 [3.13-31.06], respectively). Conclusions Identifying individuals at risk of HCV transmission during methadone treatment such as stimulant users, alcohol dependent individuals, and those at suicidal risk is necessary to optimize response to treatment.

    Voluntary methadone administration for the purpose of sedation eventually resulting in the infant's death is extremely infrequent, though it has been observed. In this report, we describe an autopsy case pertaining to a 32-month-old infant who was repeatedly exposed to methadone by his parents. Autopsy revealed a coarctation of the aorta with a focal stenosis located at the junction of the distal aortic arch and the descending aorta. Left ventricular hypertrophy was also observed. Both these findings were considered to not have played a role in the child's death. Methadone was detected in the femoral blood (0.633 mg/l), urine (5.25 mg/l), bile (2.64 mg/l), and gastric contents (1.08 mg). A segmental hair analysis showed the presence of methadone and morphine in both the proximal and distal portion of the lock. Methadone was also detected in nail samples. A segmental hair analysis performed on the younger brother of the deceased revealed the presence of methadone and morphine in both the proximal and distal segments, as well as the presence of 6-monoacetylmorphine exclusively in the distal portion. Though the parents denied any involvement in methadone administration or exposure for the purpose of sedation, the manner of death was listed as homicide. The case emphasizes the usefulness of hair analysis to identify threatening situations for the children of drug-dependent parents and possibly support measures by the authorities to recognize and intervene in these potentially fatal situations.

    The synthetic opioid methadone hydrochloride has a low molecular weight of 346 D, a high volume of distribution (4 - 7 L/kg), and is lipophilic. It is used as an analgesic and for the maintenance treatment of opiate dependence. In drug addicts, methadone is frequently involved in mixed intoxications that can lead to death. Here we present the case of a drug addict in whom a high cut-off dialysis membrane together with extended dialysis was used in the setting of suspected overdose and acute kidney injury. Although the observed dialyzer plasma clearance (31.5 mL/min) and reduction ratio (38%) were higher than previously reported for standard hemodialysis, the total amount of methadone in the spent dialysate after 1 extended dialysis session was quite low. Hence, even extended dialysis with a high cut-off membrane does not seem to offer a clinically relevant benefit in the setting of overdose for enhanced methadone removal. On the other hand, in patients undergoing high cut-off dialysis for the removal of light chains, methadone could still be used as an analgesic without an additional dose after high cut-off hemodialysis.

    An analysis of the first seven years of performance of our hospital-based emergency medical services (EMS) helicopter was conducted to evaluate the possible need for a second aircraft. A survey of seven hospitals currently operating two or more helicopters resulted in a consensus that one helicopter can effectively perform only 70 to 90 flights per month. The number of requests for our helicopter service has increased 148% from 610 to 1,512 in seven years while the number of completed missions has increased only 92% from 486 (40.5/month) to 935 (78/month). Requests denied due to inclement weather (265 in 1988) cannot be captured with a second visual-flight-rated (VFR) EMS helicopter; however, those missed due to maintenance requirements of the helicopter and overlapping requests (232 in 1988) can be captured. The need for a second aircraft exists when the number of requests for the service grows while the number of captured flights plateaus. Our data and industry survey suggests this will occur at 75 captured flights per month. Affordability and continued overall growth of trauma and other critical care referrals to the base hospital(s) is mandatory. This study provides a model for hospital-based EMS helicopter operators to apply to the decision whether to add a second aircraft. PMID:10296622

    Methadone has been the most commonly used pharmacotherapy for the treatment of opioid dependence in U.S. public sector treatment, but availability of buprenorphine as an alternative medication continues to increase. Drawing data from two community-based clinical trials that were conducted nearly contemporaneously, this study examined retention in methadone vs. buprenorphine treatment over 6 months among urban African Americans receiving treatment in one of four publicly-funded programs (N= 478; 178 methadone; 300 buprenorphine). Adjusting for confounds related to medication selection, survival analysis revealed that buprenorphine patients are at substantially higher risk of dropout compared to methadone patients (HR= 2.43; p< .001). Buprenorphine’s retention disadvantage appears to be concentrated in the earlier phases of treatment (approximately the first 50 days), after which risk of subsequent dropout becomes similar for the two medications. These findings confirm a retention disparity between methadone and buprenorphine in this population, and suggest potential avenues for future research to enhance retention in buprenorphine treatment.

    Individuals who use heroin and illicit opioids are at high risk for infection with human immunodeficiency virus (HIV) and other blood-borne pathogens, as well as incarceration. The purpose of the randomized trial reported here is to compare outcomes between participants who initiated methadone maintenance treatment (MMT) prior to release from incarceration, with those who were referred to treatment at the time of release. Participants who initiated MMT prior to release were significantly more likely to enter treatment postrelease (P < .001) and for participants who did enter treatment, those who received MMT prerelease did so within fewer days (P = .03). They also reported less heroin use (P = .008), other opiate use (P = .09), and injection drug use (P = .06) at 6 months. Initiating MMT in the weeks prior to release from incarceration is a feasible and effective way to improve MMT access postrelease and to decrease relapse to opioid use. PMID:22263710

  9. Lack of effect of chronic dextromethorphan on experimental pain tolerance in methadone-maintained patients.

    2008-09-01

    Good evidence exists to suggest that individuals on opioid maintenance for the treatment of addiction (i.e. methadone) are less tolerant of experimental pain than are matched controls or ex-opioid addicts, a phenomenon theorized to reflect opioid-induced hyperalgesia (OIH). Agonist activity at the excitatory ionotropic N-methyl-D-aspartate (NMDA) receptor on dorsal horn neurons has been implicated in the development of both OIH and its putative expression at the clinical level-opioid tolerance. The aim of this study was to evaluate the potential utility of the NMDA-receptor antagonist, dextromethorphan (DEX), to reverse or treat OIH in methadone-maintenance (MM) patients. Utilizing a clinical trial design and double-blind conditions, changes in pain threshold and tolerance [cold pressor (CP) and electrical stimulation (ES)] following a 5-week trial of DEX (titrated to 480 mg/day) in comparison with placebo was evaluated in a well-characterized sample of MM patients. The sample (n = 40) was 53% male and ethnically diverse (53% Latino, 28% African American, 10% White, 9% other), with a mean age of 48.0 years (SD = 6.97). Based on t-test analyses, no difference was found between groups on CP pain threshold, CP pain tolerance, ES pain threshold or ES pain tolerance, both pre- and postmedication. Notably, DEX-related changes significantly differed by gender, with women tending to show diminished tolerance for pain with DEX therapy. These results support that chronic high-dose NMDA antagonism does not improve tolerance for pain in MM patients, although a gender effect on DEX response is suggested. PMID:18507735

    The objective of this analysis was to compare the cost-effectiveness of clinic-based methadone maintenance therapy (MMT) and office-based buprenorphine maintenance therapy (BMT) from the perspective of third-party payers in the United States. The authors used a Markov cost-effectiveness model. A hypothetical cohort of 1000 adult, opioid-dependent patients was modeled over a 1-year time horizon. Patients were allowed to transition between the health states of in opioid dependence treatment and either abusing or not abusing opioids, or to have dropped out of treatment. Probabilities were derived from randomized clinical trials comparing methadone and buprenorphine. Costs included drug and administration, clinic visits, and therapy sessions. Effectiveness outcomes examined were (1) retention in the treatment program and (2) opioid abuse-free weeks. For retention in treatment at 1 year, MMT was more costly ($4,613 vs. $4,155) and more effective (20.3% vs. 15.9%) than BMT, resulting in an incremental cost-effectiveness ratio (ICER) of $10,437 per additional patient retained in treatment. MMT was also more effective than BMT in terms of opioid abuse-free weeks (9.2 vs. 9.1 weeks), resulting in an ICER of $8,515 per opioid abuse-free week gained. One-way sensitivity analyses found costs per week of MMT to have the largest impact on the retention-in-treatment outcome, whereas the probability of dropping out with MMT had the greatest impact on opioid abuse-free weeks. The authors conclude that MMT is cost-effective compared with BMT for the treatment of patients with opioid dependence. However, the treatment of substance abuse is complex, and decision makers should also consider individual patient characteristics when making coverage decisions. PMID:27007583

    2014-04-01

    The aim of this qualitative study was to examine the narratives of people who experience chronic pain (lasting 6 months or more) and were receiving methadone for the treatment of their opiate addiction through a major methadone clinic. This paper featured the pathway of how the participants developed chronic pain and addiction, and their beliefs of how prescription opioids would impact their addiction in the future. Thirty-four participants who experienced chronic pain and received methadone for treatment of opiate addiction were willing to tell the story of their experiences. The findings in three areas are presented: (a) whether participants experienced addiction first or pain first and how their exposures to addictive substances influenced their experiences, (b) the significance of recreational drug use and patterns of abuse behaviors leading to chronic pain, and (c) participants' experiences and beliefs about the potential for abuse of prescription opioid used for treatment of pain.

    Purpose There are more drug overdose deaths in the Untied States than motor vehicle fatalities. Yet the US vital statistics reporting system is of limited value because the data are delayed by four years. Poison centers report data within an hour of the event, but previous studies suggested a small proportion of poisoning deaths are reported to poison centers (PC). In an era of improved electronic surveillance capabilities, exposure calls to PCs may be an alternate indicator of trends in overdose mortality. Methods We used PC call counts for methadone that were reported to the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS®) System in 2006 and 2007. US death certificate data were used to identify deaths due to methadone. Linear regression was used to quantify the relationship of deaths and poison center calls. Results Compared to decedents, poison center callers tended to be younger, more often female, at home and less likely to require medical attention. A strong association was found with PC calls and methadone mortality (b = 0.88, se = 0.42, t = 9.5, df = 1, p<0.0001, R2 = 0.77). These findings were robust to large changes in a sensitivity analysis assessing the impact of underreporting of methadone overdose deaths. Conclusions Our results suggest that calls to poison centers for methadone are correlated with poisoning mortality as identified on death certificates. Calls received by poison centers may be used for timely surveillance of mortality due to methadone. In the midst of the prescription opioid overdose epidemic, electronic surveillance tools that report in real-time are powerful public health tools. PMID:22829925

  14. Methadone: six effects in search of a substance.

    What is the difference between heroin and methadone? Is this difference one of interpretation, where an 'opiate-like' substance is 'labelled' differently through social processes that arbitrarily describe methadone as 'legal' and 'therapeutic', and heroin as 'illegal' and 'harmful'? To study the nature of this difference, I follow two experiments in the United States and in France of methadone substitution, where medical practices attempt to replace heroin by methadone, and thereby to reduce the user's (illegal) drug use. In these trials, the experimenters ask precisely this question. The question of the nature of the difference between the substance's actions is further illustrated by the comparison between the substitution trials: when the experimenters describe methadone differently in different places and times, do they 'interpret' the drug differently, or is the drug itself different? I show that far too many elements vary from trial to trial to say that the 'interpretation' of the substance is all that varies. In order to explore the variation in detail, then, I draw on works about 'performance', and on the actor-network 'theory of action': what heroin and methadone do, but also also the very way in which they 'pass into action', is what varies in each trial. In the end, this question about difference is a question about action. In each trial, there is not from the start one substance with fixed or vague properties which one can then interpret in various manners. 'Substance' does not contain inherent actions from the start ('properties'). Rather, following the experimenters, it is possible to say that 'effects' are primary and that only at the end of the trial do the experimenters laboriously 'find substance' to effects.

    Background Treatment of opiate use disorders with methadone is complicated by wide interindividual variability in pharmacokinetics. To identify potentially contributing covariates in methadone pharmacokinetics, we used population pharmacokinetic modeling to estimate clearance (CL/F) and volume of distribution (V/F) for each methadone enantiomer in an ethnically diverse methadone maintained population. Methods Plasma levels of the opiate-active R-methadone and opiate-inactive S-methadone were measured in 206 methadone maintained subjects approximately two and twenty-three hours after a daily oral dose of racmethadone. A linear one-compartment population pharmacokinetic model with first-order conditional estimation with interaction (FOCE-I) was used to evaluate methadone CL/F and V/F. The influence of covariates on parameter estimates was evaluated using stepwise covariate modeling. Covariates included ethnicity, gender, weight, BMI, age, methadone dose, and 21 single nucleotide polymorphisms in genes implicated in methadone pharmacokinetics. Results In the final model, for each enantiomer, Hmong ethnicity reduced CL/F by approximately 30% and the rs2032582 (ABCB1 2677G > T/A) GG genotype was associated with a 20% reduction in CL/F. The presence of the rs3745274 minor allele (CYP2B6 515G > T) reduced CL/F by up to 20% for S-methadone only. A smaller effect of age was noted on CL/F for R-methadone. Conclusion This is the first report showing the influence of the rs2032582 and rs3745274 variants on methadone pharmacokinetics rather than simply dose requirements or plasma levels. Population pharmacokinetics is a valuable method for identifying the influences on methadone pharmacokinetic variability. PMID:25456329

    2013-01-01

    Background This study examined long-term improvement of quality of life amongst heroin users enrolled in methadone maintenance treatment (MMT). Methods The sample contained 553 heroin-dependent individuals from 4 hospitals in northern Taiwan who enrolled in MMT for an average of 184 days. Each patient signed a consent form and was assessed prospectively 3 times semi-annually. Quality of life was measured using the WHOQOL-BREF questionnaire, 26 items of which were scored by the participants. The WHOQOL-BREF consists of four domains: physical, psychological, social, and environmental. 285 and 155 participants completed 6-month and 12-month follow-ups respectively. Results After controlling for demographic and clinical characteristics, there were statistically significant improvements in the psychological and environmental domains between baseline and 6 months. Significant improvements were found in psychological and social domains between baseline and 12 months. Conclusions It is concluded that methadone maintenance treatment improves heroin users’ long-term quality of life in the psychological and social relationship domains. PMID:23865898

    Current methods of methadone analysis in untreated urine are traditionally limited to enzyme immunoassays (EIA) while confirmation techniques require specimen processing (i.e., sample clean-up) before analyzing by gas or liquid chromatography coupled with mass spectrometry (GC-MS or LC-MS-MS). EIA and traditional confirmation techniques can be costly and, at times inefficient. As an alternative approach, we present Direct Analysis in Real Time (DART™) coupled with both time-of-flight and triple quadrupole linear ion trap (Q-TRAP™) mass spectrometers for screening and confirming methadone in untreated urine specimens. These approaches require neither expensive kits nor sample clean-up for analysis. More importantly, the total combined analysis time for both screening and confirmation methods was <5 min per sample; in contrast to the 3-5 day process required by traditional EIA, GC-MS and LC-MS-MS techniques. To examine the fundamental protocol and its applicability for routine drug screening, studies were performed that included limits of detection, precision, selectivity and specificity, sample recovery and stability and method robustness. The methods described in this report were determined to be highly specific and selective; allowing for detection of methadone at 250 ng/mL, consistent with cutoffs for current EIA techniques (300 ng/mL). The results reported here demonstrate the DART™ MS platform provides rapid and selective methadone analysis and the potential for providing savings of both time and resources compared with current analysis procedures.

    Topical analgesics have many potential advantages over systemic administration. Prior work has shown potent analgesic activity of a number of topical opioids in the radiant heat tailflick assay. The current study confirms the analgesic activity of morphine and extends it to two other mu opioids, methadone and meperidine. Combinations of topical morphine and lidocaine are synergistic. Similarly, the combination of methadone and lidocaine is synergistic. While there appeared to be some potentiation with the combination of meperidine and lidocaine, it did not achieve significance. Systemically, prior studies have shown that co-administration of morphine and methadone was synergistic. The combination of morphine and methadone was also synergistic when given topically. In contrast, the combination of morphine and meperidine was not synergistic systemically and it was not synergistic topically. Thus, the pharmacology of topical opioids mimics that seen with systemic administration. Their activity in the topical model supports their potential utility while the local limitation of their actions offers the possibility of a reduced side-effect profile. PMID:20433826

    We studied the interaction of a single dose of different antidepressant medications with a single (acute) dose or implanted mini-pump (chronic) methadone administration in mice, using the hotplate assay. For the acute experiment, subthreshold doses of six antidepressant drugs were administered separately with a single dose of methadone. The addition of a subthreshold dose of desipramine or clomipramine to methadone produced significant augmentation of the methadone effect with each drug (p < 0.05). Fluvoxamine given at a fixed subthreshold dose induced a synergistic effect only with a low methadone dose. Escitalopram, reboxetine and venlafaxine given separately, each at a fixed subthreshold dose, induced no interaction. Possible clinical implications of these findings are that while escitalopram, reboxetine and venlafaxine do not affect methadone's antinociception in mice and are safe to be given together with methadone when indicated, fluvoxamine, clomipramine and desipramine considerably augment methadone-induced effects and should be avoided in this population due to the risk of inducing opiate overdose. For the chromic experiment, when a subthreshold dose of either escitalopram, desipramine or clomipramine was injected to mice following 2 weeks of methadone administration with the mini-pump, none of the antidepressant drugs strengthened methadone's analgesic effect. Further studies are needed before possible clinical implications can be drawn. PMID:24057890

    Racemic methadone is increasingly used to manage cancer pain. The authors studied 13 terminally ill patients with cancer pain, who underwent switching (rotation) from morphine to methadone. The relationship between initial morphine dose and final methadone dose, the pharmacokinetics of R- and S- methadone, and the degree of pain control and side effects were investigated. Preswitching serum morphine concentrations and second daily plasma concentrations of methadone were measured. The brief pain inventory (BPI) was used to assess pain every second day. "Worst pain" as measured by the BPI improved by >/=20% in 6 of the 13 patients. The mean morphine to methadone conversion ratio was 5.2 with wide interpatient variability (range 1.3 to 11). Average steady-state concentrations were 197 (98 to 379) mug/L and 272 (55 to 378) mug/L for R- and S-methadone, respectively. Mean population pharmacokinetic parameters for a 1-compartment model were 455 L and 338 L for apparent volume of distribution and 53.3 hours and 31.5 hours for half-life for R- and S- methadone, respectively. Bayesian estimates of apparent oral clearance for individual patients were 0.082 (0.052 to 0.112) L/kg/h and 0.117 (0.061 to 0.173) L/kg/h for R- and S- methadone, respectively (mean and 95% confidence interval). The low and variable clearance values generally resulted in slow achievement of steady-state concentrations over several days; inappropriately high plasma methadone levels occurred in 1 patient. Whereas optimal pain control was achieved in 46% of patients, there was no relationship with plasma concentrations of methadone. Best practice for methadone use in this patient group should include monitoring of both pain and methadone concentration. PMID:16778720

    Rationale Limited pharmacological data are available to guide methadone treatment during pregnancy and postpartum. Objectives Study goals were to: 1) Characterize changes in methadone dose across childbearing, 2) Determine enantiomer-specific methadone withdrawal kinetics from steady-state during late pregnancy, 3) Assess enantiomer-specific changes in methadone level/dose (L/D) ratios across childbearing, and 4) Explore relationships between CYP2B6, CYP2C19 and CYP3A4 single nucleotide polymorphisms and maternal dose, plasma concentration and L/D. Methods Methadone dose changes and timed plasma samples were obtained for women on methadone (n=25) followed prospectively from third trimester of pregnancy to three months postpartum. Results Participants were primarily white, Medicaid insured and multiparous. All women increased their dose from first to end of second trimester (mean peak increase=23 mg/day); 71% of women increased from second trimester to delivery (mean peak increase=19 mg/day). Half took a higher dose 3 months postpartum than at delivery despite significantly larger clearance during late pregnancy. Third trimester enantiomer-specific methadone half-lives (range R-methadone 14.7-24.9 hours; S-methadone 8.02-18.9 hours) were about half of those reported in non-pregnant populations. In 3 women with weekly 24-hour methadone levels after delivery, L/D increased within 1-2 weeks after delivery. Women with the CYP2B6 Q172 variant GT genotype have consistently higher L/D values for S-methadone across both pregnancy and postpartum. Conclusions Most women require increases in methadone dose across pregnancy. Given the shorter half-life and larger clearances during pregnancy, many pregnant women may benefit from split methadone dosing. L/D increases quickly after delivery and doses should be lowered rapidly after delivery. PMID:22926004

    The ability of hospital-based car seat rental programs to provide car seats inexpensively throughout an entire state and the effect of these rental programs on car seat usage by newborns were evaluated. In July 1979 individuals and groups committed to child passenger safety formed a coalition called Vermont SEAT (Seatbelts Eliminate Automobile Tragedies). During the next 3 years SEAT asked the major hospitals in the state to allow volunteers to operate car seat rental programs on their premises. The number of rental programs increased from 0 to 13; the percentage of newborns born in a hospital with a rental program increased from 0% to 99%. The estimated statewide rate of car seat usage by newborns, based on observations at discharge at five hospitals, increased from 15% to 70%. These findings suggest that a network of hospital-based car seat rental programs operated by volunteers can make car seats readily available throughout a state or region, and can significantly increase car seat usage by newborns. It is recommended that such programs be a part of comprehensive strategies to improve child passenger safety. PMID:6835761

    Opioid abuse and addiction have increased in frequency in the United States over the past 20 years. In 2009, an estimated 5.3 million persons used opioid medications nonmedically within the past month, 200000 used heroin, and approximately 9.6% of African Americans used an illicit drug. Racial and ethnic minorities experience disparities in availability and access to mental health care, including substance use disorders. Primary care practitioners are often called upon to differentiate between appropriate, medically indicated opioid use in pain management vs inappropriate abuse or addiction. Racial and ethnic minority populations tend to favor primary care treatment settings over specialty mental health settings. Recent therapeutic advances allow patients requiring specialized treatment for opioid abuse and addiction to be managed in primary care settings. The Drug Addiction Treatment Act of 2000 enables qualified physicians with readily available short-term training to treat opioid-dependent patients with buprenorphine in an office-based setting, potentially making primary care physicians active partners in the diagnosis and treatment of opioid use disorders. Methadone and buprenorphine are effective opioid replacement agents for maintenance and/or detoxification of opioid-addicted individuals. However, restrictive federal regulations and stigmatization of opioid addiction and treatment have limited the availability of methadone. The opioid partial agonist-antagonist buprenorphine/naloxone combination has proven an effective alternative. This article reviews the literature on differences between buprenorphine and methadone regarding availability, efficacy, safety, side-effects, and dosing, identifying resources for enhancing the effectiveness of medication-assisted recovery through coordination with behavioral/psychological counseling, embedded in the context of recovery-oriented systems of care.

    In Denmark, fatal poisoning among drug addicts is often related to methadone. The primary mechanism contributing to fatal methadone overdose is respiratory depression. Concurrent use of other central nervous system (CNS) depressants is suggested to heighten the potential for fatal methadone toxicity. Reduced tolerance due to a short-time abstinence period is also proposed to determine a risk for fatal overdose. The primary aims of this study were to investigate if concurrent use of CNS depressants or reduced tolerance were significant risk factors in methadone-related fatalities using segmental hair analysis. The study included 99 methadone-related fatalities collected in Denmark from 2008 to 2011, where both blood and hair were available. The cases were divided into three subgroups based on the cause of death; methadone poisoning (N=64), poly-drug poisoning (N=28) or methadone poisoning combined with fatal diseases (N=7). No significant differences between methadone concentrations in the subgroups were obtained in both blood and hair. The methadone blood concentrations were highly variable (0.015-5.3, median: 0.52mg/kg) and mainly within the concentration range detected in living methadone users. In hair, methadone was detected in 97 fatalities with concentrations ranging from 0.061 to 211ng/mg (median: 11ng/mg). In the remaining two cases, methadone was detected in blood but absent in hair specimens, suggesting that these two subjects were methadone-naive users. Extensive poly-drug use was observed in all three subgroups, both recently and within the last months prior to death. Especially, concurrent use of multiple benzodiazepines was prevalent among the deceased followed by the abuse of morphine, codeine, amphetamine, cannabis, cocaine and ethanol. By including quantitative segmental hair analysis, additional information on poly-drug use was obtained. Especially, 6-acetylmorphine was detected more frequently in hair specimens, indicating that regular abuse of

    As the most populated Persian Gulf country in West Asia, methamphetamine use in methadone maintenance treatment (MMT) is a new health concern in Iran. Methamphetamine use in MMT can originate in methadone misconceptions or the stimulant effects of methamphetamine use. Several research studies have highlighted the prevalence of methamphetamine use in Iran and conducting further studies on this issue is being developed. Opiate use is treated with MMT. But, there is no effective pharmacological treatment for methamphetamine use and cognitive-behavioral interventions have still remained the best practice. As a psychostimulant drug, methamphetamine use can lead to poor treatment outcomes or even treatment failure among patients in MMT. Therefore, the implementation of methamphetamine education and prevention programs in MMT is required. Prescribing adequate methadone dose and the treatment of comorbidities as well as, doing a series of activities outside treatment is underscored. Methamphetamine use has a chronic nature and methamphetamine treatment is a long-term procedure with a high rate of relapse. Therefore, the implementation of long-term motivational interviewing, teaching necessary skills to prevent relapse and case management is highlighted. A long-term collaboration between treatment teams, patients and their families is suggested to manage methamphetamine use in MMT. PMID:26578071

    The cost of providing and receiving treatment for opioid dependence can determine its adoption. To compare the cost of clinic-based methadone (MC, n=23), office-based methadone (MO, n=21), and office-based buprenorphine (BO, n=34) we performed an analysis of treatment and patient costs over 6 months of maintenance in patients who had previously been stabilized for at least one year. We performed statistical comparisons using ANOVA and chi-square tests and performed a sensitivity analysis varying cost estimates and intensity of clinical contact. The cost of providing one month of treatment per patient was $147 (MC), $220 (MO) and $336 (BO) (p<0.001). Mean monthly medication cost was $93 (MC), $86 (MO) and $257 (BO) (p<0.001). The cost to patients was $92 (MC), $63 (MO) and $38 (BO) (p=0.102). Sensitivity analyses, varying cost estimates and clinical contact, result in total monthly costs of $117 to $183 (MC), $149 to $279 (MO), $292 to $499(BO). Monthly patient costs were $84 to $133 (MC), $55 to $105 (MO) and $34 to $65 (BO). We conclude that providing clinic-based methadone is least expensive. The price of buprenorphine accounts for a major portion of the difference in costs. For patients, office-based treatment may be less expensive. PMID:18804923

    Low-dose memantine might have anti-inflammatory and neurotrophic effects mechanistically remote from an NMDA receptor. We investigated whether add-on memantine reduced cytokine levels and benefitted patients with opioid dependence undergoing methadone maintenance therapy (MMT) in a randomized, double-blind, controlled 12-week study. Patients were randomly assigned to a group: Memantine (5 mg/day) (n = 53) or Placebo (n = 75). The methadone dose required and retention in treatment were monitored. Plasma tumor necrosis factor (TNF)-α, C-reactive protein (CRP), interleukin (IL)-6, IL-8, transforming growth factor (TGF)-β1, and brain-derived neurotrophic factor (BDNF) levels were examined during weeks 0, 1, 4, 8, and 12. General linear mixed models were used to examine therapeutic effect. After 12 weeks, Memantine-group required a somewhat lower methadone dose than did Placebo-group (P = 0.039). They also had significantly lower plasma TNF-α and significantly higher TGF-β1 levels. We provide evidence of the benefit of add-on memantine in opioid dependent patients undergoing MMT.

    Simulation is a frequently used method for training students in health care professions and has recently gained acceptance in acute care hospital settings for use in educational programs and competency testing. Although hospital-based simulation is currently limited primarily to use in skills acquisition, expansion of the use of simulation via a modified Quality Health Outcomes Model to address systems factors such as the physical environment and human factors such as fatigue, reliance on memory, and reliance on vigilance could drive system-wide changes. Simulation is an expensive resource and should not be limited to use for education and competency testing. Well-developed, peer-reviewed simulations can be used for environmental factors, human factors, and interprofessional education to improve patients' outcomes and drive system-wide change for quality improvement initiatives.

Pharmacotherapies for this disorder using mu opiate agonists (methadone and levomethadyl acetate) and partial agonists have been developed in the last 40 years. Agonist pharmacotherapy with oral methadone for the treatment of opiate dependence was developed in clinical pharmacology studies at Rockefeller University by Dole, Nyswander, and Kreek. Further studies by this laboratory and others established that moderate to high dose treatment with methadone (80-120 mg) reduced or eliminated opiate use in outpatient settings with consequent reductions in morbidity and up to 4-fold reductions in mortality. Levomethadyl acetate (LAAM), a congener of methadone, is biotransformed to active metabolites responsible for its longer duration of action. The Federal Regulations regarding the dispensation of methadone and LAAM have recently been revised to facilitate the treatment of patients under a "medical maintenance" model. Future regulatory reform will likely involve the establishment of rules for "office based opioid treatment." PMID:12220607

    For monitoring compliance of methadone or buprenorphine maintenance patient, a method for the simultaneous determination of methadone, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), buprenorphine, norbuprenorphine, opiates (morphine, codeine, 6-monoacetylmorphine) in urine by superficially porous liquid chromatography tandem mass spectrometry was developed and validated. After enzyme digestion and liquid-liquid extraction, reverse-phase separation was achieved in 5.2 min and quantification was performed by multiple reaction monitoring. Chromatographic separation was performed at 40 °C on a reversed phase Poroshell column with gradient elution. The mobile phase consisted of water and methanol, each containing 0.1% formic acid, at a flow rate of 0.32 mL/min. Intra-day and inter-day precision were less than 12.1% and accuracy was between -9.8% and 13.7%. Extraction efficiencies were more than 68%. Although ion suppression was detected, deuterated internal standards compensated for these effects. Carryover was minimal, less than 0.20%. All analytes were stable at room temperature for 16 h, 4 °C for 72 h, and after three freeze-thaw cycles. The assay also fulfilled compound identification criteria in accordance with the European Commission Decision 2002/657/EC. We analyzed 62 urine samples from patients received maintenance therapy and found that 54.8% of the patient samples tested were detected for morphine, codeine, or 6-monoacetylmorphine. This method provides a reliable and simultaneous quantification of opiates, maintenance drugs, and their metabolites in urine samples. It facilitates the routine monitoring in individuals prescribed the drug to ensure compliance and help therapeutic process. PMID:23507455

    Methadone maintenance treatment (MMT) has been used as a treatment for opiate dependence since the mid-1960s. Evidence suggests that methadone binds to mu opiate receptors as do other opiates and induces changes in neurophysiological function. However, little is known, about how neural activity within the higher frequency gamma band (>30 Hz) while at rest changes in those stabilized on MMT despite its association with the excitation-inhibition balance within pyramidal-interneuron networks. Our study investigated differences in resting gamma power (37-41 Hz) between patients undergoing MMT for opiate dependence, illicit opiate users, and healthy controls subjects. Electroencephalographic data were recorded from 26 sites according to the international 10-20 system. Compared with the healthy controls subjects, people either undergoing MMT (mean difference [MD] = 0.32, 95% CI = 0.09-0.55, P < .01) or currently using illicit opiates (MD = 0.31, 95% CI = 0.06-0.56, P = .01) exhibited significant increased gamma power. The sLORETA (standardized low-resolution electromagnetic tomography) between-group comparison revealed dysfunctional neuronal activity in the occipital, parietal, and frontal lobes in the patients undergoing MMT. A more severe profile of dysfunction was observed in those using illicit opiates. Our findings suggest that long-term exposure to opioids is associated with disrupted resting state network, which may be reduced after MMT. PMID:26002855

    Outcomes are presented from opioid-dependent outpatients (N = 81) participating in a new community-based initiative designed to improve access to enhanced substance abuse and psychiatric services in the publicly-supported methadone maintenance treatment network in Baltimore, Maryland. The initiative, entitled Community Access to Specialized Treatment (CAST), is located at the Addiction Treatment Services (ATS), a program within this network. Network programs referred patients engaged in unremitting drug use and at risk for discharge to CAST, where they received methadone substitution, individual and group counseling within an adaptive platform, behavioral contingencies to reinforce adherence, and on-site psychiatric evaluation and care. Patients returned to their referring program after producing at least two consecutive weeks of drug-negative urine samples and full counseling adherence. CAST was well-utilized by the community. Patients had high rates of adherence to scheduled individual and group counseling services (93% and 73%, respectively); 43% of referrals successfully completed the program in an average of 101 days. This community-wide service delivery approach is a novel alternative to integrating intensive substance abuse and psychiatric care at each program within a treatment network. PMID:19717272

    Background Methadone is a unique µ-opioid receptor agonist. Although several researchers have insisted that the pharmacological effects of methadone are mediated through the blockade of NMDA receptor, the underlying mechanism by which methadone exerts its distinct pharmacological effects compared to those of other µ-opioid receptor agonists is still controversial. In the present study, we further investigated the pharmacological profile of methadone compared to those of fentanyl and morphine as measured mainly by the discriminative stimulus effect and in vitro assays for NMDA receptor binding, µ-opioid receptor-internalization, and µ-opioid receptor-mediated β-arrestin recruitment. Results We found that fentanyl substituted for the discriminative stimulus effects of methadone, whereas a relatively high dose of morphine was required to substitute for the discriminative stimulus effects of methadone in rats. Under these conditions, the non-competitive NMDA receptor antagonist MK-801 did not substitute for the discriminative stimulus effects of methadone. In association with its discriminative stimulus effect, methadone failed to displace the receptor binding of MK801 using mouse brain membrane. Methadone and fentanyl, but not morphine, induced potent µ-opioid receptor internalization accompanied by the strong recruitment of β-arrestin-2 in µ-opioid receptor-overexpressing cells. Conclusions These results suggest that methadone may, at least partly, produce its pharmacological effect as a β-arrestin-biased µ-opioid receptor agonist, similar to fentanyl, and NMDA receptor blockade is not the main contributor to the pharmacological profile of methadone.

    While methadone has been available for over 50 years, its use in opiate dependence has overshadowed its use as an analgesic. Within the last 10-15 years, though, methadone has been increasingly used to manage neuoropathic pain and cancer pain, but its use is causing an alarming number of deaths in the U.S. Last June, The Charleston Gazette ran a series titled "The Killer Cure" by Scott Finn and Tara Tuckwiller that found that the number of Americans whose deaths were caused by methadone rose from 790 in 1999 to 2,992 in 2003. The series also reported other statistics from the National Center for Health Statistics that revealed that West Virginia ranked first per capita in methadone overdose deaths, and that methadone was more likely involved in overdose deaths than any other prescription drug. Methadone has several unique properties that can be beneficial in the treatment of neuropathic pain and cancer pain unresponsive to other opioids, but some of these properties make it very dangerous and difficult to prescribe properly. As a result of these factors, methadone should not be the first-choice drug for pain and it should not be used in opioid-naive patients. The goal of this article is to provide a review of the properties and protocols for safe prescribing of methadone to help physicians recognize situations where this drug offers the greatest advantage as an analgesic.

    Severely obese patients affected by two or more chronic conditions which could mutually influence their outcome and disability can be defined as "complex" patients. The presence of multiple comorbidities often represents an obstacle for being admitted to clinical settings for the treatment of metabolic diseases. On the other hand, clinical Units with optimal standards for the treatment of pathological conditions in normal-weight patients are often structurally and technologically inadequate for the care of patients with extreme obesity. The aims of this review paper were to review the intrinsic (anthropometrics, body composition) and extrinsic (comorbidities) determinants of disability in obese patients and to provide an up-to-date definition of hospital-based multidisciplinary rehabilitation programs for severely obese patients with comorbidities. Rehabilitation of such patients require a here-and-now multidimensional, comprehensive approach, where the intensity of rehabilitative treatments depends on the disability level and severity of comorbidities and consists of the simultaneous provision of physiotherapy, diet and nutritional support, psychological counselling, adapted physical activity, specific nursing in hospitals with appropriate organizational and structural competences.

    Aims The purpose of this study was to (i) describe the weight, weight-related perceptions and lifestyle behaviours of hospital-based nurses, and (ii) explore the relationship of demographic, health, weight and job characteristics with lifestyle behaviours. Background The obesity epidemic is widely documented. Worksite initiatives have been advocated. Nurses represent an important part of the hospital workforce and serve as role models when caring for patients. Methods A sample of 194 nurses from six hospitals participated in anthropometric measurements and self-administered surveys. Results The majority of nurses were overweight and obese, and some were not actively involved in weight management behaviours. Self-reported health, diet and physical activity behaviours were low, although variable by gender, age and shift. Reports of co-worker norms supported low levels of healthy behaviours. Conclusions Findings reinforce the need to address the hospital environment and culture as well as individual behaviours for obesity control. Implications for nursing management Nurse managers have an opportunity to consider interventions that promote a climate favourable to improved health habits by facilitating and supporting healthy lifestyle choices (nutrition and physical activity) and environmental changes. Such efforts have the potential to increase productivity and morale and decrease work-related disabilities and improve quality of life. PMID:19793242

    Illicit use of opiates is the fastest growing substance use problem in the United States, and the main reason for seeking addiction treatment services for illicit drug use throughout the world. It is associated with significant morbidity and mortality related to human immunodeficiency virus, hepatitis C, and overdose. Treatment for opiate addiction requires long-term management. Behavioral interventions alone have extremely poor outcomes, with more than 80% of patients returning to drug use. Similarly poor results are seen with medication-assisted detoxification. This article provides a topical review of the three medications approved by the Food and Drug Administration for long-term treatment of opiate dependence: the opioid-agonist methadone, the partial opioid-agonist buprenorphine, and the opioid-antagonist naltrexone. Basic mechanisms of action and treatment outcomes are described for each medication. Results indicate that maintenance medication provides the best opportunity for patients to achieve recovery from opiate addiction. Extensive literature and systematic reviews show that maintenance treatment with either methadone or buprenorphine is associated with retention in treatment, reduction in illicit opiate use, decreased craving, and improved social function. Oral naltrexone is ineffective in treating opiate addiction, but recent studies using extended-release naltrexone injections have shown promise. Although no direct comparisons between extended-release naltrexone injections and either methadone or buprenorphine exist, indirect comparison of retention shows inferior outcome compared with methadone and buprenorphine. Further work is needed to directly compare each medication and determine individual factors that can assist in medication selection. Until such time, selection of medication should be based on informed choice following a discussion of outcomes, risks, and benefits of each medication. PMID:22873183

    We surveyed 150 methadone maintenance treatment program (MMTP) patients about pain, pain treatment utilization, perceived efficacy of prior pain treatment, and interest in pursuing pain treatment at the MMTP. Respondents with chronic severe pain (CSP) (i.e., pain lasting at least 6 months with moderate to severe pain intensity or significant pain interference) and “some pain” (i.e., pain reported in the previous week but not CSP) endorsed similar rates of past-week and lifetime allopathic or standard medical (with the exception of lifetime medical use of non-opiate medication) and complementary and alternative medicine (CAM) utilization for pain reduction. Prior pain treatments were perceived to be less effective by CSP than SP patients but both groups had equivalent high rates of interest in pain treatment associated with the MMTP. These findings may have implications for resource and program planning in MMT programs. PMID:19874157

    Background Methadone is the therapeutic agent of choice for the treatment of opiate addiction in pregnancy. The co-consumption (heroin, cocaine) which may influence the effects of methadone is frequent. Therefore, the impact of cocaine and heroin on the placental transfer of methadone and the placental tissue was investigated under in vitro conditions. Methods Placentae (n = 24) were ex-vivo perfused with medium (m) (control, n = 6), m plus methadone (n = 6), m plus methadone and cocaine (n = 6) or m plus methadone and heroin (n = 6). Placental functionality parameters like antipyrine permeability, glucose consumption, lactate production, hormone production (hCG and leptin), microparticles release and the expression of P-glycoprotein were analysed. Results Methadone accumulated in placental tissue. Methadone alone decreased the transfer of antipyrine from 0.60 +/- 0.07 to 0.50 +/- 0.06 (fetal/maternal ratio, mean +/- SD, P < 0.01), whereas the combination with cocaine or heroin increased it (0.56 +/- 0.08 to 0.68 +/- 0.13, P = 0.03 and 0.58 +/- 0.21 to 0.71 +/- 0.24; P = 0.18). Microparticles (MPs) released from syncytiotrophoblast into maternal circuit increased by 30% after cocaine or heroin (P < 0.05) and the expression of P-glycoprotein in the tissue increased by ≥ 49% after any drug (P < 0.05). All other measured parameters did not show any significant effect when methadone was combined with cocaine or heroine. Conclusion The combination of cocaine or heroin with methadone increase antipyrine permeability. Changes of MPs resemble findings seen in oxidative stress of syncytiotrophoblast. PMID:19519880

    Reinforcing properties of psychoactive substances are considered to be critically involved in the development and maintenance of substance dependence. While accumulating evidence suggests that the sensitivity to reinforcement values may generally be altered in chronic substance users, relatively little is known about the influence reinforcing feedback exerts on ongoing decision-making in these individuals. Decision-making was investigated using the Cambridge Risk Task, in which there is a conflict between an unlikely large reward option and a likely small reward option. Responses on a given trial were analyzed with respect to the outcome on the previous trial, providing a measure of the impact of prior feedback in modulating behavior. Five different groups were compared: (i) chronic amphetamine users, (ii) chronic opiate users in methadone maintenance treatment (MMT), (iii) chronic users of illicit heroin, (iv) ex-drug users who had been long-term amphetamine / opiate users but were abstinent from all drugs of abuse for at least 1 year and (v) matched controls without a history of illicit substance use. Contrary to our predictions, choice preference was modified in response to feedback only in opiate users enrolled in MMT. Following a loss, the MMT opiate group chose the likely small reward option significantly less frequently than controls and heroin users. Our results suggest that different opiates are associated with distinctive behavioral responses to feedback. These findings are discussed with respect to the different mechanisms of action of heroin and methadone.

    Context In developing countries, corneal diseases are the second leading cause of blindness. This corneal blindness can be treated through corneal transplantation. Though the present infrastructure is strong enough to increase keratoplasty numbers at a required rate, India has largest corneal blind population in the world. So a constant supply of high quality donor corneal tissue is the key factor for reduction of prevalence of corneal blindness. Considering the magnitude of corneal blindness and shortage of donor cornea, there is a huge gap in the demand and supply. Aim To study the potential for hospital based retrieval of donor corneal tissue in Hassan district hospital after analysing the indicated and contraindicated causes of deaths, so that hospital corneal retrieval program in Hassan district hospital can be planned. Materials and Methods The cross-sectional, retrospective and record-based study included all hospital deaths with age group more than two years occurred during one year period (January 2014 to December 2014). Data regarding demographic profile, cause of death, treatment given and presence of any systemic diseases were collected. The causes of deaths which are contraindicated for the retrieval of corneas were analysed and noted. The contraindications were based on the NPCB guidelines for standard of eye banking in India 2009. Results Out of 855 deaths, number of deaths in males (565) was greater than females (290). Numbers of deaths were highest between 41-60 years age group (343). Deaths due to HIV, septicaemia, meningitis, encephalitis, disseminated malignancies were contraindicated for corneal retrieval. Corneas could be retrieved from 736 deaths out of 855. Potential for corneal retrieval in a period of one year in Hassan District hospital was 86%. Conclusion Hospital corneal retrieval program has got a great potential to bridge the gap between the need for the cornea and actually collected corneas which will contribute enormously in

  10. Phenomenologies of the Akratic Self: Masculinity, Regrets, and HIV among Men on Methadone

    2006-01-01

    This study explores the motivational bargaining processes that constitute an “act” of heterosexual HIV risk-taking by focusing on the narrative viewpoint of two men in methadone maintenance treatment programs in the Harlem section of New York City. These men reported sexual episodes with complex motivational “event grammars” that were analyzed using qualitative methods. Building on the concept of akrasia (failure to convert intentions into action), I argue that HIV risky heterosex results from temporal displacements of instrumental rationality by two other equally relevant orientations of sexual action, namely, affectual and normative. I conclude that sexual risk occurs in the context of emotions and normative presentations of the masculine self. Consequently, a man's risk of loosing footing or consistent face vis-à-vis his female sex partner, and not the risks of HIV, becomes a priority of the sexual interaction. Sexuality is at its core social and, hence, subject to more powerful forces than personal safety or behaviorist reward. PMID:16755387

    The purpose of this study was to identify whether heroin relapse is associated with changes in the functional connectivity of the default mode network (DMN) during methadone maintenance treatment (MMT). Resting-state functional magnetic resonance imaging (fMRI) data of chronic heroin relapsers (HR) (12 males, 1 female, age: 36.1 ± 6.9 years) and abstainers (HA) (11males, 2 female; age: 42.1 ± 8.1 years) were investigated with an independent component analysis to address the functional connectivity of their DMN. Group comparison was then performed between the relapsers and abstainers. Our study found that the left inferior temporal gyrus and the right superior occipital gyrus associated with DMN showed decreased functional connectivity in HR when compared with HA, while the left precuneus and the right middle cingulum had increased functional connectivity. Mean intensity signal, extracted from left inferior temporal gyrus of HR patients, showed a significant negative correlation corresponding to the degree of heroin relapse. These findings suggest that altered functional connectivity of DMN may contribute to the potential neurobiological mechanism(s) of heroin relapse and have a predictive value concerning heroin relapse under MMT.

    Substance use and a history of childhood sexual abuse have both been identified as risk factors for unprotected sex among women, yet questions remain as to how their combined influence may differentially affect sexual risk behavior. In the current study a Generalized Linear Mixed Model was used to examine the interaction effect between current cocaine and opioid use and a history of childhood sexual abuse (CSA) on number of unprotected sexual occasions (USO) in a sample of 214 sexually active women in outpatient methadone maintenance treatment programs. Results show significant interaction effects between drug use in the past 30 days and CSA on unprotected sexual occasions. These interactions, however, differ depending on type of drug used and CSA status. For women with CSA, an increase in days of cocaine use was significantly associated with an increase in USO, whereas an increase in number of days of opiate use was not significantly associated with an increase in USO. In contrast, for women who did not report CSA, an increase in number of days of cocaine use was associated with a significant decrease in USO and number of days of opiate use was significantly correlated with an increase in USO. Findings indicate that CSA is related to unprotected sexual occasions depending on drug type and severity of use. Women with childhood sexual abuse using cocaine are at particularly high risk for having unprotected sex, which suggests that this group of women should be specifically targeted for HIV prevention interventions.

    Objective Methadone Maintenance Therapy (MMT) and detoxification to abstinence are among the most common treatment options for opiate-dependent patients. This paper compares personality traits in detoxified former heroin users and those on MMT in order to assess their relevance to treatment selection. Methods Twenty-six formerly heroin-dependent subjects receiving MMT (MM), 33 formerly heroin-dependent subjects withdrawn from MMT (MW), and 43 healthy controls were compared on the Millon Clinical Multiaxial Inventory-II (MCMI-II) and the Temperament and Character Inventory (TCI). Results On the TCI, MM patients had higher Novelty Seeking and lower Self Directedness scores than controls. Both MM and MW subjects scored higher than controls on multiple MCMI-II scales. MW but not MM subjects scored higher than controls on 2 Cluster A scales and the Delusional Disorder scale. Conclusions Schizophrenia-spectrum pathology in former opiate users may be greater than previously recognized and could potentially be relevant to treatment selection. PMID:15992397

    Introduction: Drug users have high rates of tobacco use and tobacco-related disease. Telephone quitlines promote smoking cessation, but their reach among drug users is unknown. We thus aimed to assess utilization of and barriers to telephone quitlines among methadone-maintained smokers. Methods: Subjects were opioid-dependent smokers in Bronx, New York, methadone treatment programs who were enrolled in a clinical trial of varenicline. All subjects were offered referral to a free, proactive quitline. We examined quitline records, surveyed barriers to quitline use, and queried reasons for declining referral. Results: Of the 112 subjects enrolled, 47% were male, 54% were Hispanic, and 28% were Black. All subjects were offered referral, and 25 (22% of study participants) utilized the quitline. Quitline utilizers (vs. nonutilizers) were significantly more likely to have landline phone service (72 vs. 42%, p = .01), interest in quitline participation (92 vs. 62%, p < .01), and willingness to receive calls (96 vs. 76%, p = .02). Nonutilizers were significantly more likely to report cell phone service lapse (38 vs. 14%, p = .04), and difficulty charging cell phones (19 vs. 0%, p = .02). Reasons for quitline refusal included: (a) skepticism of quitline efficacy; (b) aversion to telephone communication; (c) competing life demands (e.g., drug treatment, shelter); and (d) problems with cell phone service or minutes. Conclusions: Despite several limitations to quitline access among methadone-maintained smokers, routine quitline referral was associated with 22% utilization. To expand provision of smoking cessation treatment to opioid-dependent smokers, interventions to promote routine quitline referral in substance abuse treatment programs warrant investigation.

    2016-01-01

    Background: Opiates such as morphine are the most powerful analgesics, but their protracted use is restrained by the development of tolerance to analgesic effects. Recent works suggest that tolerance to morphine might be due to its inability to promote mu opioid receptor endocytosis, and the co-injection of morphine with a mu opioid receptor internalizing agonist like [D-Ala2,N-Me-Phe4,Gly-ol5]enkephalin reduces tolerance to morphine. So far, no studies have been conducted to evaluate the ability of methadone to reduce morphine tolerance in morphine-pretreated animals, a treatment sequence that could be encountered in opiate rotation protocol. We investigated the ability of methadone (a mu opioid receptor internalizing agonist used in therapy) to reverse morphine tolerance and the associated cellular mechanisms in the periaqueductal gray matter, a region involved in pain control. Methods: We measured analgesic response following a challenge dose of morphine in the hot plate test and investigated regulation of mu opioid receptor (coupling and endocytosis) and some cellular mechanisms involved in tolerance such as adenylate cyclase superactivation and changes in N-methyl-d-aspartate receptor subunits expression and phosphorylation state. Results: A chronic treatment with morphine promoted tolerance to its analgesic effects and was associated with a lack of mu opioid receptor endocytosis, adenylate cyclase overshoot, NR2A and NR2B downregulation, and phosphorylation of NR1. We reported that a methadone treatment in morphine-treated mice reversed morphine tolerance to analgesia by promoting mu opioid receptor endocytosis and blocking cellular mechanisms of tolerance. Conclusions: Our data might lead to rational strategies to tackle opiate tolerance in the frame of opiate rotation. PMID:26390873

    Purpose The incidence of retinal detachment in Blacks is generally considered to be low though there are few supporting studies in Africa. This study, thus, aimed at describing the clinical profile of patients with retinal detachment in Southwest Ethiopia. Methods A hospital-based study was done on all consecutive retinal detachment patients who presented to Jimma University Hospital over six months period. A semi-structured questionnaire was used to collect patients’ sociodemographic characteristics and clinical history. Comprehensive anterior and posterior segment eye examinations were done and risk factors were sought for. Statistical tests were considered significant if P < 0.05. Results A total of 94 eyes of 80 patients (1.5%) had retinal detachment (RD) and about 69% of patients were symptomatic for over a month before presentation. The mean age was 41.4 years (SD ±16.5). Fourteen patients (17.5%) had bilateral RD. At presentation, 61 eyes (64.9%) were blind from RD and 11 (13.8%) patients were bilaterally blind from RD. Rhegmatogenous RD was seen in 55 eyes (58.5%) and tractional RD in 22 eyes (23.4%). The most common risk factors were ocular trauma (32 eyes, 34.0%), myopia (23 eyes, 24.5%), posterior uveitis (13 eyes, 13.8%) and diabetic retinopathy (9 eyes, 9.6%). Most retinal breaks (25 eyes, 43.1%) were superotemporal and horse-shoe tear was the most common (19 eyes, 20.2%). Macula was off in 77 eyes (81.9%) and 38 eyes (69.1% of RRD eyes) had grade C proliferative vitreoretinopathy (PVR). Macular status was significantly associated with PVR (P=0.011), and duration of symptoms (RR=1.25, 95%CI: 1.059-1.475, P=0.040). Conclusions A significant numbers of patients with ocular problem had retinal detachment, and nearly two third of the patients presented late. Trauma and myopia were the most important risk factors. People should be educated to improve their health seeking behavior and use eye safety precautions to prevent ocular trauma. PMID:24086614

    We present a case of T.M. admitted to University Department of Psychiatry, Split University Hospital Center, in Croatia, because of the acute psychotic reaction (F23.9). The patient's urine tested positive for methadone without a history of methadone ingestion. Urine drug screen was performed with the COBAS Integra Methadone II test kit (kinetic interaction of microparticles in solution /KIMS/ methodology) by Roche. Drugs that have been shown to cross-react with methadone feature a tricyclic structure with a sulfur and nitrogen atom in the middle ring, which is common for both quetiapine and methadone. Therefore, it is plausible that this structural similarity between quetiapine and methadone could underlie the cross-reactivity on methadone drug screen. Besides quetiapine, a number of routinely prescribed medications have been associated with triggering false-positive urine drug screen results. Verification of the test results with a different screening test or additional analytical tests should be performed to avoid adverse consequences for the patients. PMID:23115954

    Background Over 80% of people in methadone treatment smoke cigarettes, and existing smoking cessation interventions have been minimally effective. Objective To develop an Information-Motivation-Behavioral Skills (IMB) Model of behavior change based smoking cessation intervention for methadone maintained smokers, we examined smoking cessation related information, motivation, and behavioral skills in this population. Methods Current or former smokers in methadone treatment (n=35) participated in focus groups. Ten methadone clinic counselors participated in an individual interview. A content analysis was conducted using deductive and inductive approaches. Results Commonly known information, motivation, and behavioral skills factors related to smoking cessation were described. These factors included: the health effects of smoking and treatment options for quitting (information); pregnancy and cost of cigarettes (motivators); and coping with emotions, finding social support, and pharmacotherapy adherence (behavioral skills). Information, motivation, and behavioral skills factors specific to methadone maintained smokers were also described. These factors included: the relationship between quitting smoking and drug relapse (information), the belief that smoking is the same as using drugs (motivator); and coping with methadone clinic culture and applying skills used to quit drugs to quitting smoking (behavioral skills). Information, motivation, and behavioral skills strengths and deficits varied by individual. Conclusions Methadone maintained smokers could benefit from research on an IMB Model based smoking cessation intervention that is individualized, addresses IMB factors common among all smokers, and also addresses IMB factors unique to this population.

    Type 1 diabetes is an autoimmune disease characterized by inflammation of pancreatic islets and destruction of {beta} cells by the immune system. Opioids have been shown to modulate a number of immune functions, including T helper 1 (Th1) and T helper 2 (Th2) cytokines. The immunosuppressive effect of long-term administration of opioids has been demonstrated both in animal models and humans. The aim of this study was to determine the effect of methadone, a {mu}-opioid receptor agonist, on type 1 diabetes. Administration of multiple low doses of streptozotocin (STZ) (MLDS) (40mg/kg intraperitoneally for 5 consecutive days) to mice resulted in autoimmune diabetes. Mice were treated with methadone (10mg/kg/day subcutaneously) for 24days. Blood glucose, insulin and pancreatic cytokine levels were measured. Chronic methadone treatment significantly reduced hyperglycemia and incidence of diabetes, and restored pancreatic insulin secretion in the MLDS model. The protective effect of methadone can be overcome by pretreatment with naltrexone, an opioid receptor antagonist. Also, methadone treatment decreased the proinflammatory Th1 cytokines [interleukin (IL)-1{beta}, tumor necrosis factor-{alpha} and interferon-{gamma}] and increased anti-inflammatory Th2 cytokines (IL-4 and IL-10). Histopathological observations indicated that STZ-mediated destruction of {beta} cells was attenuated by methadone treatment. It seems that methadone as an opioid agonist may have a protective effect against destruction of {beta} cells and insulitis in the MLDS model of type 1 diabetes.

  20. There is no age limit for methadone: a retrospective cohort study

    PubMed Central

    2011-01-01

    Background Data from the US indicates that methadone-maintained populations are aging, with an increase of patients aged 50 or older. Data from European methadone populations is sparse. This retrospective cohort study sought to evaluate the age trends and related developments in the methadone population of Basel-City, Switzerland. Methods The study included methadone patients between April 1, 1995 and March 31, 2003. Anonymized data was taken from the methadone register of Basel-City. For analysis of age distributions, patient samples were split into four age categories from '20-29 years' to '50 years and over'. Cross-sectional comparisons were performed using patient samples of 1996 and 2003. Results Analysis showed a significant increase in older patients between 1996 and 2003 (p < 0.001). During that period, the percentage of patients aged 50 and over rose almost tenfold, while the proportion of patients aged under 30 dropped significantly from 52.8% to 12.3%. The average methadone dose (p < 0.001) and the 1-year retention rate (p < 0.001) also increased significantly. Conclusions Findings point to clear trends in aging of methadone patients in Basel-City which are comparable, although less pronounced, to developments among US methadone populations. Many unanswered questions on medical, psychosocial and health economic consequences remain as the needs of older patients have not yet been evaluated extensively. However, older methadone patients, just as any other patients, should be accorded treatment appropriate to their medical condition and needs. Particular attention should be paid to adequate solutions for persons in need of care. PMID:21592331

    Aim. Poor sleep quality due to pain has been reported among opioid-dependent male patients on methadone maintenance therapy (MMT) but objective pain data are lacking. This study aimed to investigate the rate of pain-sensitivity using cold pressor test (CPT) and the relationship between pain-sensitivity and sleep quality in this population. Methods. A total of 168 male participants were included into the study. Objective pain-tolerance was evaluated at 0 h and at 24 h after the first CPT. Malay version of the Pittsburgh Sleep Quality Index (PSQI) and the subjective opiate withdrawal scale (SOWS) questionnaires were administered to evaluate the quality of sleep and withdrawal symptoms, respectively. Results. The mean age of study participants was 37.22 (SD 6.20) years old. Mean daily methadone dose was 76.64 (SD 37.63) mg/day, mean global PSQI score was 5.47 (SD 2.74) and mean averaged SOWS score was 5.43 (SD 6.91). The averaged pain-tolerance time ranged from 7 to 300 s with a mean time of 32.16 (SE 2.72) s, slightly below the cut-off score of 37.53 s. More specifically, 78.6% (n = 132) of participants were identified as pain-sensitive (averaged pain-tolerance time ≤37.53 s), and 36 (21.4%) participants were pain-tolerant (averaged pain-tolerance time >37.53 s). The pain-sensitive group reported poorer sleep quality with mean (SD) PSQI of 5.78 (2.80) compared with the pain-tolerant group with mean (SD) PSQI of 4.31 (2.18) (p = 0.005). With analysis of covariance, pain-sensitive group was found to have higher global PSQI scores (adjusted mean 5.76, 95% CI 5.29; 6.22) than pain-tolerant participants (adjusted mean 4.42, 95% CI 3.52; 5.32) (p = 0.010). Conclusions. Majority of opioid-dependent male patients on methadone treatment are pain-sensitive with CPT. Poor sleep quality is associated with cold pressor pain-sensitivity. Pain and sleep complaints in this male population should not be overlooked. PMID:25870765

    A case of death attributed to methadone acute poisoning in an infant aged 11 months is reported. A sudden infant death syndrome (SIDS) was suspected, whereas a traumatic cause of death was excluded regarding autopsy findings. Specimens were submitted to a large toxicological analysis, which included ethanol measurement by HS-GC-FID, a targeted screening for drugs of abuse and various prescription drug classes followed by quantification using UPLC-MS/MS methods. Methadone and its metabolite (EDDP) were detected in all the tested fluids, as well as in hair, with a blood concentration of methadone considered as lethal for children (73 ng/mL). The cause of death was determined to be acute "methadone poisoning", and the manner of death was "accidental". A discussion of the case circumstances, the difficulties with the interpretation of toxicological findings in children (blood concentration and hair testing), and the origin of exposure are discussed.

    Strict control routines of prescribed opiate intake in opioid maintenance treatment, OMT, are used to reduce the risk of diversion and non-prescribed methadone and buprenorphine use. While maintaining a focus on aspects of control, this article explores motivations for and practices of methadone and buprenorphine use, both inside and outside of prison and among imprisoned individuals in OMT. The participants in this qualitative study were subjected to tight external control regimes in their opioid maintenance schemes in prison, as they were prior to imprisonment due to varying degrees of 'non-compliance'. We nevertheless found them to exhibit a considerable amount of self-control, self-regulation and/or self-initiation of external control. Among the participants, a ceaseless surveillance of processes associated with methadone and buprenorphine use throughout diverse situations, relations and contexts was encountered. We conclude that, in opioid maintenance treatment, some individuals might know what particular configurations of internal and external control they need in order to achieve their own treatment goals. The drug users' capacities for execution of control, as well as their delegations of control to others, may be seen as resources throughout the course of treatment. PMID:24594221

    In order to develop a fast and simple procedure for methadone analysis in biological fluids, a graphite paste electrode (GPE) was modified with the ion-pair of methadone-phosphotungstic acid, and multiwalled carbon nanotubes (MWCNTs). Optimized composition of the electrode with respect to graphite powder:paraffin oil:MWCNTs:ion pair, was 58:30:8:4 (w/w%). The electrode showed a near-Nernstian slope of 58.9 ± 0.3 mV/decade for methadone in a wide linear range of 1.0 × 10(-8)-4.6 × 10(-3)M, with a detection limit of 1.0 × 10(-8)M. The electrode response was independent of pH in the range of 5-11, with a fast response time (~4s) at 25 °C. The sensor showed high selectivity and was successfully applied to the determination of sub-micromolar concentrations of methadone in human blood serum and urine samples, with recoveries in the range of 95-99.8%. The average recovery of methadone from tablets (5 mg/tablet) by using the proposed method was 98%. The life time of the modified electrode was more than 5 months, due to the characteristic of GPE which can be cut off and fresh electrode surface be available. A titration procedure was performed for methadone analysis by using phosphotungstic acid, as titrating agent, which showed an accurate end point and 1:1 stoichiometry for the ion-pair formed (methadone:phosphotungstic acid). The simple and rapid procedure as well as excellent detection limit and selectivity are some of the advantages of the proposed sensor for methadone. PMID:27040192

    Objective Increasing use of methadone in withdrawal programs has increased methadone poisoning in children. This research aimed to study the causes of incidence of poisoning in children and its side-effects. Materials & Methods In this research, The hospital records of all methadone-poisoned children referred to Hamadan’s Be’sat Hospital from June 2007 to March 2013, were studied. Children with a definite history of methadone use or proven existence of methadone in their urine, were studied. Results During 5 years, 62 children with the mean age of 53.24±29.50 months were hospitalized due to methadone use. There was a significant relationship between delayed referral to hospital and increased bradypnea. According to their history, 25.8% and 58.1% of the children had been poisoned by methadone tablet and syrup, respectively. The most common initial complaint expressed by parents, was decreased consciousness (85.5%). During the initial examination, decreased consciousness, meiosis, and respiratory depression were observed in 91.9%, 82.3%, and 69.4% of the cases, respectively. Nine patients required mechanical ventilation. There was a significant relationship between the need for mechanical ventilation and seizure with initial symptom of emesis. There were two cases of death (3.2%), both of which were secondary to prolonged hypoxia and brain death. There was a significant relationship between poor patient prognosis (death) and presence of cyanosis in early symptoms, seizure, hypotension, duration of decreased consciousness, and duration of mechanical ventilation. Conclusion This research indicated that the occurrence of seizure, hypotension, and cyanosis in the early stages of poisoning is associated with an increased risk of side effects and death and are serious warning signs. Early diagnosis and intervention can improve outcomes of methadone-poisoned children. PMID:24949049

    Objective To examine the population-wide overdose risk emerging from the prescription of methadone and buprenorphine for opioid substitution treatment in England and Wales. Design Retrospective administrative data study. Setting National databases for England and Wales. Participants/cases Drug-related mortality data were drawn from the Office for National Statistics, and prescription data for methadone and buprenorphine were obtained from the National Health Service for the years 2007–2012. During this 6-year period, a total of 2366 methadone-related deaths and 52 buprenorphine-related deaths were registered, corresponding to 17 333 163 methadone and 2 602 374 buprenorphine prescriptions issued. The analysis encompassed poisoning deaths among members of the wider population of England and Wales who consumed, but were not prescribed these medications, in addition to patients prescribed methadone or buprenorphine. Main outcome measures Mortality risk: substance-specific overdose rate per 1000 prescriptions issued; relative risk ratio of methadone in relation to buprenorphine. Results During the years 2007–2012, the pooled overdose death rate was 0.137/1000 prescriptions of methadone, compared to 0.022/1000 prescriptions of buprenorphine (including buprenorphine-naloxone). The analysis generated a relative risk ratio of 6.23 (95% CI 4.79 to 8.10) of methadone in relation to buprenorphine. UK Borders Agency data were taken into consideration and revealed that only negligible amounts of methadone and buprenorphine were seized on entering UK territory between 2007 and 2012, suggesting domestic diversion. Conclusions Our analysis of the relative safety of buprenorphine and methadone for opioid substitution treatment reveals that buprenorphine is six times safer than methadone with regard to overdose risk among the general population. Clinicians should be aware of the increased risk of prescribing methadone, and tighter regulations are needed to prevent its

    Purpose. Methadone, a synthetic opioid agonist, is an effective alternative to strong opioids (morphine, hydromorphone, oxycodone, and buprenorphine) and is widely available as an oral formulation. Few data have been published so far on the use of intravenous (i.v.) methadone for the management of severe or refractory cancer pain. Methods. We followed 10 consecutives cancer patients with severe pain, treated with IV methadone. All had advanced disease and had already received strong opioids, some in association with ketamine. Pain was assessed at T0, T24 hours, and at the end of the treatment. Results. All patients benefited from the switch to IV methadone with a reduction of pain on VAS after 24 hours (median: 4/10; range 0–5) until the end of the treatment (all cases <3/10). The median starting dose was 100 mg/day (range 20–400) and the final dose remained stable with a median of 100 mg/day (range 27–700). The median duration of IV methadone was 11 days (range 2–59). No cardiac toxicity had been observed. Conclusions. IV methadone is an effective pain relieving alternative for the treatment of severe cancer pain, especially in refractory pain syndrome. Moreover, we did not observe any toxicity (neurological or cardiac) or any other major side effects and the treatment was overall well tolerated. More extensive comparative studies should be planned.

    Background Recent policy initiatives in Baltimore City, MD significantly reduced access disparities between methadone and buprenorphine in the publicly-funded treatment sector. Objectives This study examines reasons for choosing buprenorphine over methadone among patients with access to both medications. Methods This study was embedded within a larger clinical trial conducted at two outpatient substance abuse treatment programs offering buprenorphine. Qualitative and quantitative data on treatment choice were collected for new patients starting buprenorphine treatment (n=80). The sample consisted of predominantly urban African American (94%) heroin users who had prior experience with non-prescribed street buprenorphine (85%) and opioid agonist treatment (68%). Qualitative data were transcribed and coded for themes, while quantitative data were analyzed using descriptive and bivariate statistics. Results Participants typically conveyed their choice of buprenorphine treatment as a decision against methadone. Buprenorphine was perceived as a helpful medication while methadone was perceived as a harmful narcotic with multiple unwanted physical effects. Positive experiences with non-prescribed “street buprenorphine” were a central factor in participants’ decisions to seek buprenorphine treatment. Conclusions Differences in service structure between methadone and buprenorphine did not strongly influence treatment-seeking decisions in this sample. Personal experiences with medications and the street narrative surrounding them play an important role in treatment selection decisions. Scientific Significance This study characterizes important decision factors that underlie patients’ selection of buprenorphine over methadone treatment. PMID:23617873

    Background Methadone is a synthetic opioid that has been used to relieve severe pain in addiction withdrawal. Unfortunately, due to non-standard supply and storage, the incidence of poisoning and deaths caused by this drug is increasing daily. The purpose of this study was to determine the underlying causes of methadone poisoning in children admitted to Kerman Afzalipour Hospital, Kerman University of Medical Sciences, Iran, during 2012. Methods This cross-sectional study was performed on 105 children diagnosed with methadone poisoning and admitted to the pediatric emergency ward at Kerman Afzalipour Hospital. The required information was recorded through interviews with parents, patient examination, and if necessary telephone calls with the parents. The data were analyzed using SPSS software. Findings Mean age of children was 3.9 ± 2.4 years and 59.0% of them were boys. Most parents had a high school diploma or a lower level of education. In all cases, a family member or relative, or at least one person in a party they attended was an addict. In most cases, methadone was fed to the child by mistake instead of water or other drugs. Parental substance abuse, employment status, and family income were significantly associated with methadone poisoning. Conclusion Training of methadone storage in individuals who need to use this drug can help to prevent accidental ingestion and poisoning of children. PMID:27274794

    Background Despite growing concern about illicit methadone use in the US and other countries, there is little data about the prevalence and correlates of methadone use in large urban areas. We assessed the prevalence and examined correlates of lifetime and recent illicit methadone use in New York City (NYC). Methods 1,415 heroin, crack, and cocaine users aged 15–40 years were recruited in NYC between 2000 and 2004 to complete interviewer-administered questionnaires. Results In multivariable logistic regression, non-injection drug users who used illicit methadone were more likely to be heroin dependent, less than daily methamphetamine users and to have a heroin using sex partner in the last two months. Injection drug users who used illicit methadone were more likely to use heroin daily, share injection paraphernalia and less likely to have been in a detoxification program and to have not used marijuana in the last six months. Conclusion The results overall suggest that illicit (or street) methadone use is likely not a primary drug of choice, but is instead more common in concert with other illicit drug use. PMID:18957116

    1. Following a subcutaneous dose (4mg/kg) of [3H]methadone, peak levels of drug occurred in plasma, tissues and selected areas of the central nervous system (CNS) 2h after injection in both non-tolerant and tolerant dogs. Highest concentrations of methadone were attained in bile and lung compared to other tissues. 2. Levels of methadone in plasma, tissue and CNS of tolerant and non-tolerant animals were not markedly different up to 8h after injection, but a much faster rate of egression of free drug (lower t1/2) was observed subsequently in tolerant dogs. 3. Peak levels of methadone in various areas of the CNS ranged between 2-7 (spinal cord) to 3-6 (thalamus) mug/g in non-tolerant and 3-0 -rebellum) to 4-1 (thalamus) mug/g in tolerant dogs 2h after injection. No marked accumulation of methadone occurred in selected areas of the CNS in spite of the persistence of drug in these areas. 4. The plasma protein electrophoretic profiles did not differ between control, non-tolerant and tolerant dogs. 5. Similar qualitative patterns of metabolites were observed in non-tolerant and tolerant dogs and the development of tolerance did not appear to modify the metabolic pathways of methadone.

    The neutron therapy facility at the Gershenson Radiation Oncology Center, Harper University Hospital in Detroit has been operational since September 1991. The d(48.5)+Be beam is produced in a gantry mounted superconducting cyclotron designed and built at the National Superconducting Cyclotron Laboratory (NSCL). Measurements were performed in order to obtain the physical characteristics of the neutron beam and to collect the data necessary for treatment planning. This included profiles of the dose distribution in a water phantom, relative output factors and the design of various beam modifiers, i.e., wedges and tissue compensators. The beam was calibrated in accordance with international protocol for fast neutron dosimetry. Dosimetry and radiobiology intercomparions with three neutron therapy facilities were performed prior to clinical use. The radiation safety program was established in order to monitor and reduce the exposure levels of the personnel. The activation products were identified and the exposure in the treatment room was mapped. A comprehensive quality assurance (QA) program was developed to sustain safe and reliable operation of the unit at treatment standards comparable to those for conventional photon radiation. The program can be divided into three major parts: maintenance of the cyclotron and related hardware; QA of the neutron beam dosimetry and treatment delivery; safety and radiation protection. In addition the neutron beam is used in various non-clinical applications. Among these are the microdosimetric characterization of the beam, the effects of tissue heterogeneity on dose distribution, the development of boron neutron capture enhanced fast neutron therapy and variety of radiobiology experiments.

  3. Rationale and design of a randomized controlled trial of varenicline directly observed therapy delivered in methadone clinics

    Background Tobacco cessation medication adherence is one of the few factors shown to improve smoking cessation rates among methadone-maintained smokers, but interventions to improve adherence to smoking cessation medications have not yet been tested among methadone treatment patients. Methadone clinic-based, directly observed therapy (DOT) programs for HIV and tuberculosis improve adherence and clinical outcomes, but have not been evaluated for smoking cessation. We describe a randomized controlled trial to evaluate whether a methadone clinic-based, directly observed varenicline therapy program increases adherence and tobacco abstinence among opioid-dependent drug users receiving methadone treatment. Methods/Design We plan to enroll 100 methadone-maintained smokers and randomize them to directly observed varenicline dispensed with daily methadone doses or treatment as usual (self-administered varenicline) for 12 weeks. Our outcome measures are: 1) pill count adherence and 2) carbon monoxide-verified tobacco abstinence. We will assess differences in adherence and abstinence between the two treatment arms using repeated measures models. Discussion This trial will allow for rigorous evaluation of the efficacy of methadone clinic-based, directly observed varenicline for improving adherence and smoking cessation outcomes. This detailed description of trial methodology can serve as a template for the development of future DOT programs and can guide protocols for studies among opioid-dependent smokers receiving methadone treatment.

    In Amsterdam a longitudinal, prospective and multidisciplinary study on the development of infants of drug-dependent mothers (IDDM) was started in 1983: 35 IDDM and 35 reference infants were originally enrolled. The drug-dependent women had used combinations of methadone, heroin, cocaine and other drugs during pregnancy. Of the IDDM, 80% had to be treated pharmaceutically for neonatal abstinence symptoms (NAS). Physical, neurological, cognitive and the socio-emotional development of the children were studied regularly from birth until 5.5 years of age. Differences between the reference group and the IDDM were found most clearly in cognitive development. The IDDM also had more behavioural problems at some of the ages studied. No group differences were seen in motor development. So far the results of the study show that IDDM and their caregivers need extra support in order to improve early communication and the children's cognitive development. PMID:7531042

    Whilst unsupervised injectable methadone and diamorphine treatment has been part of the British treatment system for decades, the numbers receiving injectable opioid treatment (IOT) has been steadily diminishing in recent years. In contrast, there has been a recent expansion of supervised injectable diamorphine programs under trial conditions in a number of European and North American cities, although the evidence regarding the safety, efficacy and cost effectiveness of this treatment approach remains equivocal. Recent British clinical guidance indicates that IOT should be a second-line treatment for those patients in high-quality oral methadone treatment who continue to regularly inject heroin, and that treatment be initiated in newly-developed supervised injecting clinics. The Randomised Injectable Opioid Treatment Trial (RIOTT) is a multisite, prospective open-label randomised controlled trial (RCT) examining the role of treatment with injected opioids (methadone and heroin) for the management of heroin dependence in patients not responding to conventional substitution treatment. Specifically, the study examines whether efforts should be made to optimise methadone treatment for such patients (e.g. regular attendance, supervised dosing, high oral doses, access to psychosocial services), or whether such patients should be treated with injected methadone or heroin. Eligible patients (in oral substitution treatment and injecting illicit heroin on a regular basis) are randomised to one of three conditions: (1) optimized oral methadone treatment (Control group); (2) injected methadone treatment; or (3) injected heroin treatment (with access to oral methadone doses). Subjects are followed up for 6-months, with between-group comparisons on an intention-to-treat basis across a range of outcome measures. The primary outcome is the proportion of patients who discontinue regular illicit heroin use (operationalised as providing >50% urine drug screens negative for markers of

    For people seeking treatment, the course of heroin addiction tends to be chronic and relapsing, and longer duration of treatment is associated with better outcomes. Heroin addiction is strongly associated with deviant behaviour and crime, and the objectives in treating heroin addiction have been a blend of humane support, rehabilitation, public health intervention and crime control. Reduction in street heroin use is the foundation on which all these outcomes are based. The pharmacological basis of maintenance treatment of dependent individuals is to minimize withdrawal symptoms and attenuate the reinforcing effects of street heroin, leading to reduction or cessation of street heroin use. Opioid maintenance treatment can be moderately effective in suppressing heroin use, although deviations from evidence-based approaches, particularly the use of suboptimal doses, have meant that treatment as delivered in practice may have resulted in poorer outcomes than predicted by research. Methadone treatment has been ‘programmatic’, with a one-size-fits-all approach that in part reflects the perceived need to impose discipline on deviant individuals. However, differences in pharmacokinetics and in side-effects mean that many patients do not respond optimally to methadone. Injectable diamorphine (heroin) provides a more reinforcing medication for some ‘nonresponders’ and can be a valuable option in the rehabilitation of demoralized, socially excluded individuals. Buprenorphine, a partial agonist, is a less reinforcing medication with different side-effects and less risk of overdose. Not only is it a different medication, but also it can be used in a different paradigm of treatment, office-based opioid treatment, with less structure and offering greater patient autonomy.

    Background Methadone is an effective and inexpensive opioid for cancer pain treatment. It has been reported as difficult to use in the outpatient setting due to its variable relative potency and long half-life. The purpose of this study was to determine the outcome of methadone initiation or rotation for cancer pain treatment in outpatient settings. Methods Chart review of 189 consecutive patients who underwent methadone initiation or rotation in our palliative care outpatient center. Data were collected regarding demographic and clinical characteristics, symptoms, and opioid side effects at baseline and for 2 follow up visits(F1,F2). Failure was defined as methadone discontinuation by the palliative care physician or patient's hospitalization for uncontrolled pain or methadone-related side effects at F1. Results 100(53%) initiations and 89(47%) rotations were conducted. Success rates for methadone initiation and rotation were 82/89(92%) and 85/100(84%) respectively. Mean(standard deviation) age was 60(11) years. 100(53%) patients were female, 138(73%) white, 182(96%) had solid cancers. The main reason for rotation was pain (65/89 patients, 47%). Median(interquartile range, IR) pain scores (Edmonton Symptom Assessment System/0–10) were 6(5–8), 4(3–6), and 3(2–5) at baseline, F1, and F2, respectively(p<0.0001). Median(IR) daily methadone dose for initiation and rotation was 10(5–15)mg and 15(10–30)mg at F1(p<0.0001) and 10(8–15)mg and 18(10–30)mg at F2(p<0.0001), respectively. Constipation and nausea improved (p<0.005) after initiation/rotation to methadone. Frequency of sedation, hallucinations, myoclonus, and delirium did not increase after initiation/rotation to methadone. Conclusions Outpatient methadone initiation and rotation for cancer pain treatment were safe, with high success rate and low side effect profile. PMID:19924788

    Background Opioids are commonly administered to critically ill children for analgesia and sedation, but many patients experience opioid withdrawal upon discontinuation. The authors’ institution developed a protocol for using methadone to prevent opioid withdrawal in children who have received morphine by continuous IV infusion for 5 days or longer in the pediatric intensive care unit (PICU). Objectives The primary objectives were to determine if opioids were tapered according to the protocol and to determine the conversion ratio for IV morphine to oral methadone that was used. Secondary objectives were to describe the methadone dosage used and the clinical outcomes, to evaluate adjustments to methadone dosing, and to report the incidence of adverse effects. Methods A retrospective analysis of charts was conducted for pediatric patients who had received morphine by continuous IV infusion for 5 days or longer followed by methadone in the PICU between May 2008 and August 2009. Validated scoring systems (the Withdrawal Assessment Tool and the State Behavioral Scale) were used to assess symptoms of withdrawal and degree of sedation, respectively. Results Forty-three patients were included in the study, with median age of 8 months (range 0.25–201 months). For 31 patients (72%), the protocol was not used, and there were no patients for whom the protocol was followed to completion. The median duration of weaning was 10 days (range 0–91 days). The conversion ratio for IV morphine to oral methadone was 1:0.78 for anticipated 5-day weaning and 1:0.98 for anticipated 10-day weaning. During the first 10 days of weaning, 18 patients (42%) experienced withdrawal symptoms. The methadone dose was increased for 11 (26%) of the 43 patients. Patients were sedated for a median of 1 day (range 0–9 days), were comfortable for a median of 6.5 days (range 1–64 days), and were agitated for a median of 2.5 days (range 0–23 days). Naloxone was required for 2 patients. Conclusions

    This randomized, controlled study (n = 256) was conducted to compare three interventions designed to promote hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccination completion, among clients undergoing methadone maintenance treatment (MMT) in Los Angeles and Santa Monica. The participants were randomized into three groups: Motivational Interviewing-Single Session (MI-Single), Motivational Interviewing-Group (MI-Group), or Nurse-Led Hepatitis Health Promotion (HHP). All three treatment groups received the 3-series HAV/HBV vaccine. The MI sessions were provided by trained therapists, the Nurse-Led HHP sessions were delivered by a research nurse. The main outcome variable of interest was improvement in HBV and HCV knowledge, measured by a 6-item HBV and a 7-item HCV knowledge and attitude tool that was administered at baseline and at 6-month follow-up. The study results showed that there was a significant increase in HBV- and HCV-related knowledge across all three groups (p < 0.0001). There were no significant differences found with respect to knowledge acquisition among the groups. Irrespective of treatment group, gender (P = 0.008), study site (P < 0.0001) and whether a participant was abused as a child (P = 0.017) were all found to be predictors of HCV knowledge improvement; only recruitment site (P < 0.0001) was found to be a predictor of HBV knowledge. The authors concluded that, although MI-Single, MI-Group and Nurse-Led HHP are all effective in promoting HBV and HCV knowledge acquisition among MMT clients, Nurse-Led HHP may be the method of choice for this population as it may be easier to integrate and with additional investigation may prove to be more cost efficient.

    2011-01-01

    Background In the last few years there seems to be an emerging interest for including the patients' perspective in assessing methadone maintenance treatment (MMT), with treatment satisfaction surveys being the most commonly-used method of incorporating this point of view. The present study considers the perspective of patients on MMT when assessing the outcomes of this treatment, acknowledging the validity of this approach as an indicator. The primary aim of this study is to evaluate the concordance between improvement assessment performed by two members of the clinical staff (a psychiatrist and a nurse) and assessment carried out by MMT patients themselves. Method Patients (n = 110) and their respective psychiatrist (n = 5) and nurse (n = 1) completed a scale for assessing how the patient's condition had changed from the beginning of MMT, using the Patient Global Impression of Improvement scale (PGI-I) and the Clinical Global Impression of Improvement scale (CGI-I), respectively. Results The global improvement assessed by patients showed weak concordance with the assessments made by nurses (Quadratic-weighted kappa = 0.13, p > 0.05) and by psychiatrists (Quadratic-weighted kappa = 0.19, p = 0.0086), although in the latter, concordance was statistically significant. The percentage of improved patients was significantly higher in the case of the assessments made by patients, compared with those made by nurses (90.9% vs. 80%, Z-statistic = 2.10, p = 0.0354) and by psychiatrists (90.9% vs. 50%, Z-statistic = 6.48, p < 0.0001). Conclusions MMT patients' perception of improvement shows low concordance with the clinical staff's perspective. Assessment of MMT effectiveness should also focus on patient's evaluation of the outcomes or changes achieved, thus including indicators based on the patient's experiences, provided that MMT aim is to be more patient centred and to cover different needs of patients themselves.

    2014-01-01

    Background Health technology assessment (HTA) is increasingly performed at the local or hospital level where the costs, impacts, and benefits of health technologies can be directly assessed. Although local/hospital-based HTA has been implemented for more than two decades in some jurisdictions, little is known about its effects and impact on hospital budget, clinical practices, and patient outcomes. We conducted a mixed-methods systematic review that aimed to synthesize current evidence regarding the effects and impact of local/hospital-based HTA. Methods We identified articles through PubMed and Embase and by citation tracking of included studies. We selected qualitative, quantitative, or mixed-methods studies with empirical data about the effects or impact of local/hospital-based HTA on decision-making, budget, or perceptions of stakeholders. We extracted the following information from included studies: country, methodological approach, and use of conceptual framework; local/hospital HTA approach and activities described; reported effects and impacts of local/hospital-based HTA; factors facilitating/hampering the use of hospital-based HTA recommendations; and perceptions of stakeholders concerning local/hospital HTA. Due to the great heterogeneity among studies, we conducted a narrative synthesis of their results. Results A total of 18 studies met the inclusion criteria. We reported the results according to the four approaches for performing HTA proposed by the Hospital Based HTA Interest Sub-Group: ambassador model, mini-HTA, internal committee, and HTA unit. Results showed that each of these approaches for performing HTA corresponds to specific needs and structures and has its strengths and limitations. Overall, studies showed positive impacts related to local/hospital-based HTA on hospital decisions and budgets, as well as positive perceptions from managers and clinicians. Conclusions Local/hospital-based HTA could influence decision-making on several aspects

    The purpose of this project was to define education and training requirements for hospital-based dentists to efficiently and meaningfully participate in a hospital disaster response. Eight dental faculty with hospital-based training and/or military command and CBRNE (chemical, biological, radiological, nuclear, and explosive) expertise were recruited as an expert panel. A consensus set of recommended educational objectives for hospital-based dentists was established using the following process: 1) identify assumptions supported by all expert panelists, 2) determine current advanced dental educational training requirements, and 3) conduct additional training and literature review by various panelists and discussions with other content and systems experts. Using this three-step process, educational objectives that the development group believed necessary for hospital-based dentists to be effective in treatment or management roles in times of a catastrophic event were established. These educational objectives are categorized into five thematic areas: 1) disaster systems, 2) triage/medical assessment, 3) blast and burn injuries, 4) chemical agents, and 5) biological agents. Creation of training programs to help dentists acquire these educational objectives would benefit hospital-based dental training programs and strengthen hospital surge manpower needs. The proposed educational objectives are designed to stimulate discussion and debate among dental, medical, and public health professionals about the roles of dentists in meeting hospital surge manpower needs.

    Importance Growing methadone use in pain management has raised concerns regarding its safety relative to other long-acting opioids. Methadone may increase risk for both lethal respiratory depression related to accidental overdose and life-threatening ventricular arrhythmias. Objective To compare risk of out-of-hospital death in users of methadone for non-cancer pain to that for comparable users of sustained-release (SR) morphine. Design Retrospective cohort study. Setting Tennessee Medicaid, 1997 through 2009. Participants Cohort included current users of morphine SR or methadone 30–74 years of age without cancer or other life-threatening illness and not in a hospital or nursing home. At cohort entry, 32,742 and 6,014 had filled a prescription for morphine SR or methadone, respectively. The median age was 48 years, 58% were female, and comparable proportions had received cardiovascular, psychotropic, and other musculoskeletal medications. Nearly 90% of patients received the opioid for either back or other musculoskeletal pain. The median daily doses prescribed for morphine SR and methadone were 90mg and 40mg, respectively. Main Outcomes and Measures The primary study endpoint was out-of-hospital mortality, given that opioid-related deaths typically occur outside the hospital. Results There were 477 deaths during 28,699 person years of followup, or 166 deaths per 10,000 person-years. After control for study covariates, current methadone users had a 46% increased risk of death during followup, with an adjusted hazard ratio (HR) of 1.46 (95% confidence interval 1.17–1.83, p = .0008), resulting in 72 (27–130) excess deaths per 10,000 person-years. Methadone users of doses ≤20mg/day, the lowest dose quartile, had increased risk (HR =1.59 [1.01–2.51], p = .0461) relative to a comparable dose of morphine SR (<60mg/day). Conclusions and Relevance The increased risk of death observed for users of methadone, even for low doses, supports recommendations that it

    Introduction: Methadone has been used as a drug to detoxify opioid tolerance. Naloxane precipitated morphine withdrawal behaviours were attenuated by venlafaxine as an antidepressant. On the contrary, after detoxifying the opioids, spontaneous withdrawal syndrome may occur with pain sensitivity. Therefore the present study aimed to examine the effects of chronic methadone (70 mg/kg, in drinking water, 7 days), venlafaxine (80 mg/kg/day, intraperitoneally, 7 days) and their combinations with the spontaneous morphine withdrawal syndrome and pain sensitivity. Methods: Twenty eight young male Sprague-Dawley rats were randomly divided into 4 groups: control, venlafaxine treated, methadone treated and venlafaxine + methadone treated. Morphine sulfate (10 mg/kg/day, subcutaneously, 4 days) was injected to all animals. Then primary withdrawal behaviours and tail flick test were performed. The test was then followed by methadone or its vehicle administration. Second intervention was venlafaxine or its vehicle injection. Then final withdrawal behaviours and tail flick test were performed. Results: Combination of chronic methadone substitution and venlafaxine administration, significantly reduced freezing behaviour of spontaneous morphine withdrawal syndrome (P<0.01, 379±144%). Chronic methadone administration (P<0.05, 35±8% difference with venlafaxine treated group) induced hyperalgesia. A positive correlation (P=0.001, +63%) was observed between the animals final freezing scores and their response latencies to the painful stimulus. Discussion: Combination of chronic methadone and venlafaxine administrations reduces freezing withdrawal behaviour. Further investigations on analgesic interventions are needed to overcome this hyperalgesia.

  15. Disciplining addictions: the bio-politics of methadone and heroin in the United States.

    PubMed

    Bourgois, P

    2000-06-01

    Biomedical understanding of methadone as a magic-bullet pharmacological block to the euphoric effects of heroin is inconsistent with epidemiological and clinical data. An ethnographic perspective on the ways street-based heroin addicts experience methadone reveals the quagmire of power relations that shape drug treatment in the United States. The phenomenon of the methadone clinic is an unhappy compromise between competing discourses: A criminalizing morality versus a medicalizing model of addiction-as-a-brain-disease. Treatment in this context becomes a hostile exercise in disciplining the unruly misuses of pleasure and in controlling economically unproductive bodies. Most of the biomedical and epidemiological research literature on methadone obscures these power dynamics by technocratically debating dosage titrations in a social vacuum. A foucaultian critique of the interplay between power and knowledge might dismiss debates over the Swiss experiments with heroin prescription as merely one more version of biopower disciplining unworthy bodies. Foucault's ill-defined concept of the specific intellectual as someone who confronts power relations on a practical technical level, however, suggests there can be a role for political as well as theoretical engagement with debates in the field of applied substance abuse treatment. Meanwhile, too many heroin addicts who are prescribed methadone in the United States suffer negative side effects that range from an accentuated craving for polydrug abuse to a paralyzing sense of impotence and physical and emotional discomfort.

    A 6-year-old male child was scheduled for a dental procedure requiring conscious sedation. Prior to the procedure, the child was administered a dental cocktail containing chloral hydrate, hydroxyzine, and methadone. After returning from the dentist, the child appeared groggy and was allowed to sleep. A few hours later, he was found unresponsive, and following resuscitation attempts at a local medical center, he was pronounced dead. Toxicological analyses of femoral blood indicated the presence of hydroxyzine at less than 0.54 μg/mL, trichloroethanol (TCE) at 8.3 μg/mL, and methadone at 0.51 μg/mL. No meperidine was detected. The cause of death was reported to be due to the toxic effects of methadone. The toxicological analysis was corroborated by the analysis of the contents of the dental cocktail, which revealed the presence of hydroxyzine, chloral hydrate, and methadone. Residue from a control sample obtained from the same pharmacy, but administered to a different subject, was found to contain hydroxyzine, chloral hydrate, and meperidine. This report represents the first known fatality due to accidental substitution of methadone in a dental cocktail. PMID:21871161

    This study examined the uses of diverted methadone and buprenorphine among opiate-addicted individuals recruited from new admissions to methadone programs and from out-of-treatment individuals recruited from the streets. Self-report data regarding diversion were obtained from surveys and semi-structured qualitative interviews. Approximately 16% (n=84) of the total sample (N=515) reported using diverted (street) methadone 2–3 times per week for six months or more, and for an average of 7.8 days (SD=10.3) within the past month. The group reporting lifetime use of diverted methadone as compared to the group that did not report such use was less likely to use heroin and cocaine in the 30 days prior to admission (ps < .01) and had lower ASI Drug Composite scores (p < .05). Participants in our qualitative sub-sample (n=22) indicated that street methadone was more widely used than street buprenorphine and that both drugs were largely used as self-medication for detoxification and withdrawal symptoms. Participants reported using low dosages and no injection of either medication was reported. PMID:19874152

    A statewide network of hospital-based low-cost car seat rental and educational programs, operated by volunteers, was begun in Vermont in 1979. In four years the rate of correct car seat usage by newborns at hospital discharge increased from less than 16% to 71%. High usage rates appear to continue in the first two years of life. It is hypothesized that availability of car seats, direct educational intervention in the hospitals, high visibility, and indirect educational processes in the community contributed to these changes. It is concluded that hospital-based programs should be included in comprehensive strategies to improve child passenger safety. PMID:6520003

    Methadone is a drug that has found widespread utility in the management of opioid addiction and pain. Along with its popularity, methadone has also earned an infamous reputation for causing prolongation of the QT interval and an increased risk of torsades de pointes. In this article we will give a brief overview of the long QT syndromes, followed by an in-depth look at the current pathophysiologic mechanisms of methadone induced QT prolongation, a review of the existing literature and the current concepts regarding the prevention and management of methadone induced torsades de pointes. In addition, we explore the idea and implications of a genetic link between methadone induced prolongation of the QT interval and torsades de pointes. PMID:24653586

  2. Poor Man's Methadone: A Case Report of Loperamide Toxicity.

    2015-12-01

    Loperamide, a common over-the-counter antidiarrheal drug and opioid derivative, is formulated to act upon intestinal opioid receptors. However, at high doses, loperamide crosses the blood-brain barrier and reaches central opioid receptors in the brain, leading to central opiate effects including euphoria and respiratory depression. We report the case of a young man found dead in his residence with a known history of drug abuse. At autopsy, the only significant findings were a distended bladder and bloody oral purge. Drug screening found nontoxic levels of alprazolam, fluoxetine, and marijuana metabolites. Liquid chromatography time-of-flight mass spectrometry found an unusual set of split isotope peaks consistent with chlorine. On the basis of autopsy and toxicological findings, loperamide toxicity was suspected because of its opioid properties and molecular formula containing chlorine. A sample of loperamide was analyzed by liquid chromatography time-of-flight mass spectrometry, resulting in a matching mass and retention time to the decedent's sample. Subsequently, quantitative testing detected 63 ng/mL of loperamide or more than 6 times of therapeutic peak concentration. Cause of death was determined as "toxic effects of loperamide with fluoxetine and alprazolam." Because of its opioid effects and easy accessibility, loperamide is known as "poor man's methadone" and may go undetected at medical and forensic drug screening. PMID:26355852

    Expectations about future behavior have been shown to have a positive relationship with subsequent behavior. For patients in drug treatment, recovery should manifest changes in drug use and in cognitive perceptions of being able to refrain from use. The present study identified latent patterns of the longitudinal relationship between drug use expectation and illegal drug use during treatment. Latent variable mixture modeling identified three patterns of change over successive 3-month intervals during treatment: Improvers (48%), Decliners (33%), and Continuing Users (19%). The sample consisted of 497 patients in community-based outpatient methadone treatment. The utility of the latent patterns was shown through their relationship to treatment engagement, where Continuing Users had lower counseling rapport and time in treatment. These latent patterns also differed on drug use measures at follow-up. Additional analyses of expectations with measures of opioid use, cocaine use, or criminality yielded similar latent patterns. Expectations about future drug use were found to be a useful measure of cognitive change corresponding to drug use change. Its potential as a brief treatment management tool is noted. PMID:17218066

    Objectives This manuscript evaluates physician monitoring practices and incidence of cardiac side effects following initiation of methadone for treatment of chronic pain as compared to patients who began treatment for chronic pain with morphine sustained release (SR). Design We retrospectively reviewed medical record data on all new initiations of methadone and compared results of physician monitoring practices to patients with new initiations of morphine SR. A standardized chart tool was used to capture clinical data. Data related to health service utilization and clinical diagnoses were obtained from the VA clinical information system. Setting A single VA medical center in the Pacific Northwest. Patients Chronic pain patients prescribed methadone (n=92) or morphine (n=90) in the calendar year 2008. Results There was no difference between patients prescribed methadone versus patients prescribed morphine SR in the likelihood of receiving an electrocardiogram (ECG) prior to initiating medication (53% versus 54%) or in the year after opioid initiation (37% versus 40%). The two groups also did not differ in rates of developing prolonged QTc intervals (>450 ms) (11% versus 17%). Seventy-two percent of all patients discontinued their long-acting opioid regimens before 90 days due to adverse effects or insufficient pain relief. Conclusion Despite recommendations for standardized assessment and cardiac risk monitoring, few patients prescribed methadone received an ECG, and this occurred at a rate that did not differ from patients prescribed morphine SR. Patients discontinued both medications at high rates. Further research is needed to evaluate the clinical significance of QTc prolongation in patients treated with methadone. PMID:24353045

    Background: This study was designed to evaluate the role of epidural methadone-lidocaine in cancer pain combined or not to epidural dexamethasone. Methods: In all, 72 cancer patients, 32- to 67-year-old were randomized to six groups (n=12) and prospectively studied to examine analgesia and adverse effects for 3 weeks. Patients received single-dose protocol epidural test drugs: Control group (CG) received epidural 40-mg lidocaine diluted to 10-ml volume with saline. Dexamethasone group (DG) 40-mg lidocaine plus 10-mg dexamethasone. The 2.5MetG 2.5-mg epidural methadone with 40-mg lidocaine; the 5MetG, 5-mg epidural methadone plus 40-mg lidocaine, the 7.5MetG, 7.5-mg epidural methadone plus 40-mg lidocaine and finally the 7.5Met-DexG, 7.5-mg methadone with 40-mg lidocaine and 10-mg dexamethasone. Results: Groups CG, DG and 2.5MetG were similar regarding analgesia and side effects. Patients from 5MetG and 7.5MetG took 3±1 and 5±1 days, respectively, to restart oral morphine. Patients from 7.5MetDG took 14±2 to restart oral morphine (P<0.001). Daily somnolence and appetite improved in the 7.5MetDG during 2-week evaluation (P<0.005). Fatigue improved for both DG and 7.5MetDG during 2-week evaluation (P<0.005). By the third week of evaluation, all patients were similar. Conclusions: Epidural methadone plus lidocaine resulted in dose-dependent analgesia, further improved by epidural dexamethasone, which also improved fatigue. PMID:23322191

    2013-01-01

    Background Illicit use of methadone and buprenorphine has been described as a growing problem in Sweden in recent years, and has been associated with an increased drug-related mortality. Critics claim that the substances have become popular among adolescents and that they function as a gateway to heroin use. The aim of this study is to investigate, firstly, the extent to which illicit use of methadone and buprenorphine occurs among adolescents and young adults in Sweden, and secondly, at what stage in a user’s drug career these substances tend to appear. Methods The study is based on surveys and structured interviews on drug use among various populations of young people, in addition to qualitative interviews with 86 informants who, in their professional capacity, encounter adolescents or young adults who are using illicit drugs. Results Illicit use of methadone and buprenorphine is rare among young people in Sweden. According to high school surveys, less than 0.1% have tried these substances. Among young drug users in general, few have tried the substances, and there is nothing to indicate that they act as gateway drugs. Among adolescents and young adults with severe drug problems, however, the illicit use of methadone and buprenorphine is more common (54% in a compulsory care sample). These substances normally enter the drug career late, and few use them as their main drug of choice. Other prescription drugs, like benzodiazepines and tramadol, are used by adolescents to a far greater extent. Diversion and illicit use of methadone and buprenorphine is not seen as a serious problem by the professionals interviewed. A general view is that the substances are mainly used by people with a heroin or polydrug addiction, often for “self-medication” purposes. However, several informants express concern that methadone and buprenorphine may cause fatalities among young drug users without an opioid tolerance. Conclusions Illicit use of methadone and buprenorphine among

    Introduction Elder abuse, a universal human rights problem, is associated with many negative consequences. In most jurisdictions, however, there are no comprehensive hospital-based interventions for elder abuse that address the totality of needs of abused older adults: psychological, physical, legal, and social. As the first step towards the development of such an intervention, we undertook a systematic scoping review. Objectives Our primary objective was to systematically extract and synthesize actionable and applicable recommendations for components of a multidisciplinary intersectoral hospital-based elder abuse intervention. A secondary objective was to summarize the characteristics of the responses reviewed, including methods of development and validation. Methods The grey and scholarly literatures were systematically searched, with two independent reviewers conducting the title, abstract and full text screening. Documents were considered eligible for inclusion if they: 1) addressed a response (e.g., an intervention) to elder abuse, 2) contained recommendations for responding to abused older adults with potential relevance to a multidisciplinary and intersectoral hospital-based elder abuse intervention; and 3) were available in English. Analysis The extracted recommendations for care were collated, coded, categorized into themes, and further reviewed for relevancy to a comprehensive hospital-based response. Characteristics of the responses were summarized using descriptive statistics. Results 649 recommendations were extracted from 68 distinct elder abuse responses, 149 of which were deemed relevant and were categorized into 5 themes: Initial contact; Capacity and consent; Interview with older adult, caregiver, collateral contacts, and/or suspected abuser; Assessment: physical/forensic, mental, psychosocial, and environmental/functional; and care plan. Only 6 responses had been evaluated, suggesting a significant gap between development and implementation of

    The main goal of periodontal therapy is to establish an oral environment compatible with periodontal health by the physical disruption of the plaque biofilm and adjunctive chemical means if required. Implicit in this objective is the ongoing requirement of detection and interception of new and recurrent disease, which continues at selected intervals for the life of the dentition after the initial ("active") phase of periodontal treatment. This concept of ongoing periodontal maintenance therapy has been embraced as the mandatory requirement for favourable periodontal outcomes based on institutional clinical trials and in practice-based studies in various parts of the world. This review examines the ramifications of periodontal maintenance therapy based upon a multi-level assessment of logistic issues and risk factors at three levels: (1) The patient level - treatment time; patient attendance compliance; and homecare measures, antiseptics/antibiotics and smoking. (2) The level of the individual tooth - tooth loss; and evaluation of success versus survival. (3) The level of each tooth surface ("site") - probing depth, loss of attachment and bleeding on probing; and changes in clinical attachment levels. In spite of the diversity of studies conducted, there is agreement on the efficacy of periodontal maintenance therapy when compared with studies on untreated populations and in treated cases that were not maintained.

    INTRODUCTION Concomitant opioid abuse is a serious problem among patients receiving methadone maintenance treatment (MMT) for opioid use disorder. This is an exploratory study that aims to identify predictors of the length of time a patient receiving MMT for opioid use disorder remains abstinent (relapse-free). METHODS Data were collected from 250 MMT patients enrolled in addiction treatment clinics across Southern Ontario. The impact of certain clinical and socio-demographic factors on the outcome (time until opioid relapse) was determined using a Cox proportional hazard model. RESULTS History of injecting drug use behavior (hazard ratio (HR): 2.26, P = 0.042), illicit benzodiazepine consumption (HR: 1.07, P = 0.002), and the age of onset of opioid abuse (HR: 1.10, P < 0.0001) are important indicators of accelerated relapse among MMT patients. Conversely, current age is positively associated with duration of abstinence from illicit opioid use, serving as a protective factor against relapse (HR: 0.93, P = 0.003). CONCLUSION This study helps to identify patients at increased risk of relapse during MMT, allowing health care providers to target more aggressive adjunct therapies toward high-risk patients.

    Although there is an abundance of interventional studies to increase breastfeeding rates, little is known about how to support and promote breastfeeding among mothers on opioid maintenance treatment (OMT). The studies on maternal OMT mainly focus on medication excreted in breast milk and breastfeeding benefits for infants with neonatal abstinence syndrome (NAS). We aim to review interventions to improve breastfeeding outcomes among mothers on OMT to make recommendations for practice and future research. We searched CINAHL, PubMed, PsycINFO, and the Cochrane Database of Systematic Reviews for articles, preferably experimental/quasi-experimental studies published within the past 10 years, that examined interventions to increase rates of breastfeeding initiation and duration among mothers on OMT. Nine studies met our inclusion criteria, comprising 5 categories: 4 combined obstetric and addiction care, 1 rooming-in, 1 Baby-Friendly hospital, 2 inpatient/outpatient NAS treatment, and 1 divided methadone dose. Breastfeeding rates were relatively higher for divided methadone dose (81% initiated any breastfeeding) and rooming-in (62% initiated any breastfeeding); lower in Baby-Friendly hospital (24%) and inpatient/outpatient NAS treatment (45% and 24%, respectively); and mixed in combined obstetric and addiction care programs (2 studies reported 70% and 76%; 2 studies reported 17% and 28%). Studies that included both methadone and buprenorphine did not specify breastfeeding results by medication. We recommend future research to differentiate breastfeeding types and duration by OMT medication. Qualitative studies are needed to explore maternal view on breastfeeding regarding need, barrier, and motivating factors in order to develop effective interventions to promote breastfeeding among mothers on OMT.

    Background: Inadequate pain control has a significant role in maternal and neonatal health in early post-partum period which interferes with breastfeeding and has a negative influence on child normal growth. The aim of this study is evaluation of subcutaneous methadone effectiveness on post-operative pain control. Materials and Methods: Double blind randomized prospective clinical trial involving 60 term pregnancy patients through 2008 to 2009 Undergo cesarean. Inclusion criteria: Prime gravid candidate of elective cesarean and spinal anesthesia class 1 or 2. Known case of drug allergy and methadone interaction, addiction, uncontrolled medical disease excluded. Case group injected 10 mg of subcutaneous methadone in the site of incision before final suture. Morphine was a pain reliever in follow up examination. Data include mean of pain, nausea and vomiting, MAP, etc., collected and analyzed by independent-T test and Man Whitney test. Results: Although mean usage of morphine between groups was not significant statistically but the mean pain severity (P value < 0.05) and mean satisfactory (P value = 0.02) was statistically significant between groups. Other parameters were not statistically significant. Conclusion: We suggest subcutaneous methadone as a safe pain reliever in post cesarean section patients. PMID:25337527

    Waiting lists for methadone treatment have existed in many U.S. communities, but little is known nationally about what patient and service system factors are related to admission delays that stem from program capacity shortfalls. Using a combination of national data sources, this study examined patterns in capacity-related admission delays to outpatient methadone treatment in 40 U.S. metropolitan areas (N = 28,920). Patient characteristics associated with admission delays included racial/ethnic minority status, lower education, criminal justice referral, prior treatment experience, secondary cocaine or alcohol use, and co-occurring psychiatric problems. Injection drug users experienced fewer delays, as did self-pay patients and referrals from health care and addiction treatment providers. Higher community-level utilization of methadone treatment was associated with delay, whereas delays were less common in communities with higher utilization of alternative modalities. These findings highlight potential disparities in timely admission to outpatient methadone treatment. Implications for improving treatment access and service system monitoring are discussed.

    Opioid use during pregnancy can result in the newborn being physically dependent on the substance, thus experiencing drug withdrawal, termed neonatal abstinence syndrome (NAS). Buprenorphine and methadone are two drugs used to treat opioid withdrawal and are approved for use in pregnancy. Quantification of these compounds in umbilical cord plasma would help assess in utero exposure of neonates in cases of buprenorphine or methadone use during pregnancy. An LC-MS/MS method using solid-phase extraction sample preparation was developed and validated for the simultaneous quantification of methadone, buprenorphine, norbuprenorphine, and glucuronide metabolites in umbilical cord plasma. The average accuracy (percentage error) and precision (relative standard deviation) were <15% for each validated concentration. Our data establishes a 2 week maximum freezer storage window in order to achieve the most accurate cord plasma concentrations of these analytes. Additionally, we found that the umbilical cord tissue analysis was less sensitive compared with analysis with umbilical cord blood plasma, indicating that this may be a more appropriate matrix for determination of buprenorphine and metabolite concentrations. This method was successfully applied to the analysis of cord blood from women with known buprenorphine or methadone use during pregnancy. PMID:25808363

    OBJECTIVES: This study examined two major methadone treatment factors, visit frequency and methadone dose, posited to be important in reducing intravenous drug use and human immunodeficiency virus (HIV) transmission. METHODS: One hundred fifty opiate-dependent subjects randomly assigned to four groups received 50 or 80 mg of methadone and attended a clinic 2 or 5 days per week. RESULTS: Survival analysis indicated higher dropout rates for groups having five vs two visits per week (Chi2[1]=7.76). Higher proportions of opiate-positive results on urine screens were associated with lower methadone doses (F[1,91]=4.74). CONCLUSIONS: Receiving take-home doses early in treatment enhanced treatment retention. The 50-mg dose combined with five visits per week produced the worst outcome. Fewer visits enhanced retention at 50 mg, but opiate use rates were higher at this dose than they were for either 80-mg group. The HIV infection rate at entry was 9%. No subjects seroconverted during the study. Risk behaviors for acquired immunodeficiency syndrome declined over time regardless of group/dose assignment. These results have important implications for modification of regulatory and clinic policy changes. PMID:9584030

    1988-05-01

    We developed a method of analyzing revenues and expenses in a hospital-based ambulatory pediatric practice. Results of an analysis of the Children's Medical Group (CMG) at the University of Chicago Medical Center demonstrate how changes in collection rates, practice expenses, and hospital underwriting contribute to the financial outcome of the practice. In this analysis, certain programmatic goals of the CMG are achieved at a level of just under 12,000 patient visits per year. At this activity level, pediatric residency program needs are met and income to the CMG physicians is maximized. An ethical problem from the physician's perspective is created by seeking profit maximization. To accomplish this end, the CMG physicians would have to restrict their personal services to only the better-paying patients. This study serves to underscore the importance of hospital-based physicians and hospital administrators structuring fiscal incentives for physicians that mutually meet the institutional goals for the hospital and its physicians.

    This article provides radiologists with the information that they need to know to participate meaningfully in negotiating or renegotiating an exclusive hospital-based radiology service agreement. It discusses the contract negotiation process, including how to identify and prioritize contract objectives, and how to assess and create bargaining leverage. Options for achieving contract longevity, for resolving "turf" issues and for achieving financial objectives are also addressed. The article further explains the key regulatory issues that shape exclusive hospital-based radiology service agreements, including antitrust, fraud and abuse, Stark Law, HIPAA, tax, and Medicare reimbursement considerations. The author discusses the contract negotiation process from both the radiology group and hospital perspectives. He suggests that successful negotiation will depend on "fitting" the group's contracting agenda with the hospital's priorities, organizational structure, culture and resources. PMID:17411635

    In circumstances in which child sexual abuse/assault is suspected, pediatric guidelines recommend referral to services such as multidisciplinary hospital-based violence treatment centers, for specialized medical treatment, forensic documentation, and counseling. As little is known about how such services are perceived, the objective of this case report was to measure the satisfaction of nonoffending guardians of child sexual abuse/assault victims who presented for care at Ontario's hospital-based sexual assault treatment centers. Of the 1,136 individuals who reported sexual abuse/assault and were enrolled in a province-wide service evaluation, 58 were 11 years old and younger. Thirty-three guardians completed a survey. Ratings of care were overwhelmingly positive, with 97% of respondents indicating that they would recommend these services. Nonetheless, it is important to evaluate these pediatric sexual assault services frequently to ensure ongoing optimal, family-centered care. PMID:26910267

    Little published information exists to guide health care institutions in establishing syringe exchange program (SEP) services. To address this gap, this article discusses organizational issues encountered in the implementation of a hospital-based SEP in San Francisco, California (USA). Investigators collaborated with a community organization in implementing a county hospital-based SEP. SEP services integrated into a public hospital presented unique challenges directly related to their status as a health care institution. In the course of introducing SEP services into a hospital setting as part of a clinical trial, various ethical, legal, and logistical issues were raised. Based on these experiences, this paper provides guidance on how to integrate an SEP into a traditional health care institution. PMID:20397875

    Major changes brought about by managed care have redefined the nursing profession. Current trends such as case management, downsizing, restructuring of the workforce, and changes in the patient profile have had numerous effects, particularly on job satisfaction among hospital-based nurses. Strategies to improve job satisfaction during this era of increased managed care penetration include enhanced communication mechanisms, support from hospital administration, implementation of care models that promote professional nursing practice, adequate staffing, and competitive salaries and benefits.

    Background An innovative, three-year training programme, the Bachelor of Clinical Medical Practice (BCMP), for mid-level medical healthcare workers was started in 2009 by the Department of Family Medicine, University of Pretoria. Aim To measure the students’ perceptions of the instructional quality of district hospital-based training. Setting Training of students took place at clinical learning centres in rural district hospitals in the Mpumalanga and Gauteng provinces. Methods A survey using the MedEd IQ questionnaire was performed in 2010 and 2011 to measure BCMP second- and third-year students’ perceptions of instructional quality of district hospital-based training. The MedEd IQ questionnaire is composed of four subscales: preceptor activities, learning opportunities, learner involvement and the learning environment. Composite scores of instructional quality were used to present results. Results The preceptor activities, learning opportunities and the learning environment were considered by second- and third-year BCMP students to be of consistently high instructional quality. In the area of learner involvement, instructional quality increased significantly from second to third year. Conclusion Overall, instructional quality of district hospital-based training was high for both second- and third-year BCMP students, and the instructional quality of learner involvement being significantly higher in third year students. The MedEd IQ tool was a useful tool for measuring instructional quality and to inform programme quality improvement. PMID:27543282

    Background The P300 component of the auditory evoked potential is an indicator of attention dependent target processing. Only a few studies have assessed cognitive function in substituted opiate addicts by means of evoked potential recordings. In addition, P300 data suggest that chronic nicotine use reduces P300 amplitudes. While nicotine and opiate effects combine in addicted subjects, here we investigated the P300 component of the auditory event related potential in methadone substituted opiate addicts with and without concomitant non-opioid drug use in comparison to a group of control subjects with and without nicotine consumption. Methods We assessed 47 opiate addicted out-patients under current methadone substitution and 65 control subjects matched for age and gender in an 2-stimulus auditory oddball paradigm. Patients were grouped for those with and without additional non-opioid drug use and controls were grouped for current nicotine use. P300 amplitude and latency data were analyzed at electrodes Fz, Cz and Pz. Results Patients and controls did not differ with regard to P300 amplitudes and latencies when whole groups were compared. Subgroup analyses revealed significantly reduced P300 amplitudes in controls with nicotine use when compared to those without. P300 amplitudes of methadone substituted opiate addicts were in between the two control groups and did not differ with regard to additional non-opioid use. Controls with nicotine had lower P300 amplitudes when compared to patients with concomitant non-opioid drugs. No P300 latency effects were found. Conclusion Attention dependent target processing as indexed by the P300 component amplitudes and latencies is not reduced in methadone substituted opiate addicts when compared to controls. The effect of nicotine on P300 amplitudes in healthy subjects exceeds the effects of long term opioid addiction under methadone substitution. PMID:17986348

    Background Many opiate users require prescribed medication to help them achieve abstinence, commonly taking the form of a detoxification regime. In UK prisons, drug users are nearly universally treated for their opiate use by primary care clinicians, and once released access GP services where 40% of practices now treat drug users. There is a paucity of evidence evaluating methadone and buprenorphine (the two most commonly prescribed agents in the UK) for opiate detoxification. Aim To evaluate whether buprenorphine or methadone help to achieve drug abstinence at completion of a reducing regimen for heroin users presenting to UK prison health care for detoxification. Design Open-label, pragmatic, randomised controlled trial in three prison primary healthcare departments in the north of England. Method Prisoners (n = 306) using illicit opiates were recruited and given daily sublingual buprenorphine or oral methadone, in the context of routine care, over a standard reduced regimen of not more than 20 days. The primary outcome measure was abstinence from illicit opiates at 8 days post detoxification, as indicated by urine test (self-report/clinical notes where urine sample was not feasible). Secondary outcomes were also recorded. Results Abstinence was ascertained for 73.7% at 8 days post detoxification (urine sample = 52.6%, self report = 15.2%, clinical notes = 5.9%). There was no statistically significant difference in the odds of achieving abstinence between methadone and buprenorphine (odds ratio [OR] = 1.69; 95% confidence interval [CI] = 0.81 to 3.51; P = 0.163). Abstinence was associated solely with whether or not the participant was still in prison at that time (15.22 times the odds; 95% CI = 4.19 to 55.28). The strongest association for lasting abstinence was abstinence at an earlier time point. Conclusion There is equal clinical effectiveness between methadone and buprenorphine in achieving abstinence from opiates at 8 days post detoxification within prison

    In the current experiment, we used the saccadometric test to study the effect of a single therapeutic dose of methadone on the integrity of cortico-subcortical brain functioning. In this prospective study, we used the Saccadometer System (Advanced Clinical Instrumentation, Cambridge, UK). The saccadometric test was performed before and 1.5 hours after methadone dosing. We analyzed the following saccadic parameters: latency, duration, amplitude, average and peak velocity, and processing performance (promptness) as well as a number of different types of saccades (like correct/incorrect, under/overshoot, and left-sided/right-sided). The sample consists of 40 subjects with an average 18 years of opioid addiction. The mean age is 35.3 ± 7 (80% males and 20% females). The mean period of heroin dependence is 15.3 ± 6.3 years. The mean daily dose of methadone in substitution therapy is 90 ± 26.5 mg. After administration of a single therapeutic dose of methadone, there were statistically significant differences in the values of saccade duration and latency when compared to the values before the drug administration. Average duration of saccade was significantly longer [51.40 ± 8.75 ms versus 48.93 ± 6.91 ms, z = 2.53, p = .01] and average latency was significantly longer [198.85 ± 52.57 ms versus 183.05 ± 30.95 ms, z = 2.09 p < .03]. This is the first study to test the therapeutic effect of daily methadone dosing on the integrity of the cortico-subcortical brain functions as measured by the saccadometry. More research is needed to explore the effect of illicit opioid use on the integrity of brain structures and functions, and the protective effect of opioid agonist therapy on reversing the damaging effects of illicit opioid use.

    Methadone (MET) maintenance has been used successfully for many years in the rehabilitation of heroin addicts. MET, a typical m{mu}-opioid receptor agonist, exists as two enantiomers and is used clinically as the racemic mixture. However, R-(-)-MET has a 10-fold higher affinity for m{mu} receptors than S-(+)-MET (IC{sub 50}: 3.0 nM and 26.4 nM, respectively) and R-(-)-MET is almost entirely responsible for the therapeutic actions of the racemate. In order to examine the pharmacokinetics and stereoselectivity of the drug, we have synthesized both [{sup 11}C]MET and R-(-)-[{sup 11}C]MET. Preparing the precursor by one-step approach to the N-demethylated methadone was precluded as other investigators cited problems with intramolecular cyclization. Therefore, a four-step synthesis using MET (or R-(-)-MET) as starting material was required to obtain the precursor, followed by a two-step radiolabeling synthesis (N-methylation followed by oxidation) to obtain [{sup 11}C]MET (or R-(-)-[{sup 11}C]MET). Comparative PET studies in the same baboon showed peak striatal uptake was 0.022%/cc at 5 minutes with a half time of clearance from peak of 100 minutes for R-(-)-[{sup 11}C]MET and a peak uptake of 0.013%/cc with a half time of 90 min for [{sup 11}C]MET. R-(-)-[{sup 11}C]MET also showed a slower disappearance in plasma. Both tracers showed higher C-11 in basal ganglia (BG), thalamus and midbrain relative to the cerebellum (CB) and occipital cortex (OC) but the BG/OC ratio was higher for R-(-)-[{sup 11}C]MET (1.3 vs 1.1). Pretreatment with naloxone (1 mg/kg, iv) increased R-(-)-[{sup 11}C]MET uptake in all brain regions whereas unlabeled MET slightly increased C-11 clearance in BG, OC and CB. These initial results show higher brain concentration and specificity of the pharmacologically active enantiomer of methadone along with significant non-specific binding.

    In this commentary, we take the recent introduction of methadone treatment in response to emerging problems of HIV linked to heroin addiction in Kenya as a case for reflecting on the social science of implementation science. We offer a framework of 'evidence-making intervention' which we hold as distinct from mainstream 'evidence-based intervention' approaches. Whilst accepting that interventions are shaped in their contexts, evidence-based intervention approaches tend to imagine a stable intervention object with universal effect potential. By contrast, an evidence-making intervention approach investigates how an intervention, and the knowledge which constitutes it, is made locally, through its processes of implementation. Drawing on qualitative research generated in Kenya prior to (2012-2013) and during (2014-2015) the implementation of methadone treatment, we explore the making of 'methadone promise' as a case of evidence-making intervention. We show how enactments of methadone promise make multiple methadones, through which a binary is negotiated between the narratives of methadone as hope for addiction recovery and methadone as hope for HIV prevention. Addiction recovery narratives predominate, despite methadone's incorporation into policy via its globally supported HIV prevention evidence-base. Key practices in the making of methadone promise in Kenya include its medicalization, and renaming, as 'medically assisted treatment' - or simply 'MAT' - which distance it from prior constitutions elsewhere as a drug of substitution, and the visualisation of its effects wherein unhealthy people can be seen and shown to have become well. We also show how actors seek to protect the story of methadone promise from counter narratives, including through mass media projects. We conclude that there is no single biomedical object of methadone intervening on a single biological body across contexts, and no single universe of evidence. By giving weight to local rather than

    Previous studies suggest that fatal poisoning deaths involving methadone occur more frequently on the weekends. We assessed changes in the daily pattern of mortality because of methadone poisoning following a review of drug misuse services in 1996 and publication of revised clinical guidelines in 1999. We also compared this to the daily pattern of deaths involving heroin/morphine. The Office for National Statistics provided data on all deaths in England and Wales between 1993 and 2003 for which methadone and heroin/morphine were mentioned on the coroner's certificate of death registration after inquest, with or without alcohol or other drugs. There were 3098 deaths involving methadone. The death rate increased up to 1997 and then declined. Initially, there was a marked excess of deaths occurring on Saturdays. The rate of decline was greatest for deaths occurring on Saturdays. As a result, the Saturday peak disappeared (P = 0.006). There were 6328 deaths involving heroin/morphine. No change in the daily pattern of heroin/morphine deaths was observed during the study period. Although the marked change in the epidemiology of methadone deaths coincided with recommendations for service redevelopment and clinical management of methadone treatment, the contribution of improved prescribing practice or treatment services is unclear.

    Analysing drug residues in wastewater (wastewater analysis) to monitor the consumption of those drugs in the population has become a complementary method to epidemiological surveys. In this method, the excretion factor of a drug (or the percentage of drug metabolites excreted through urine) is a critical parameter for the back-estimation of the consumption of a drug. However, this parameter is usually derived from a small database of human pharmacokinetic studies. This is true for methadone and codeine, the two most commonly used opioids and also common substances of abuse. Therefore, we aimed to refine the current excretion factors used for estimating methadone and codeine by analysing published data from the literature on the excretion of methadone, its main metabolite, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), and codeine. Our review included both human drug pharmacokinetic studies and wastewater analysis studies. We found that while the commonly used excretion factor of methadone (~27.5%) was relatively accurate, the excretion factor of EDDP, a better biomarker for methadone consumption in sewer epidemiology, should be twice that of methadone (i.e. 55%) instead of the current equal or half values. For codeine, the excretion factor should be ~30% instead of 63.5% or 10% as previously used in wastewater analysis studies. Data from wastewater analysis studies could be used in this way to refine the excretion factors of the drugs of interest. PMID:27295047

    Cocaine decreases methadone and buprenorphine plasma concentrations. HIV infection and/or antiretroviral medication use may impact these relationships. We sought to determine the association between recent cocaine use and methadone and buprenorphine concentrations in HIV-infected and uninfected subjects in clinical care. R- and S-methadone or buprenorphine and norbuprenorphine concentrations were assessed at 0.5, 1, 2, and 24 hours after dosing in subjects with confirmed cocaine use and abstinence. We compared methadone and buprenorphine concentrations for cocaine use vs. abstinence, by HIV status in 16 subjects receiving methadone (6 HIV-infected) and 17 receiving buprenorphine (8 HIV-infected). With recent cocaine use, peak R-methadone (244 vs. 297 ng/mL, p = 0.03) and peak S-methadone (285 vs. 339 ng/mL); p = 0.03 concentrations were lower in HIV-uninfected subjects only. Peak buprenorphine and norbuprenorphine concentrations were unchanged regardless of cocaine use or HIV status. Cocaine may decrease methadone concentrations in HIV-uninfected subjects. HIV infection or its treatment may attenuate cocaine's effect on methadone. PMID:25480096

    Background: Massage therapy is offered increasingly in US medical facilities. Although the United States has many massage schools, their education differs, along with licensure and standards. As massage therapy in hospitals expands and proves its value, massage therapists need increased training and skills in working with patients who have various complex medical concerns, to provide safe and effective treatment. These services for hospitalized patients can impact patient experience substantially and provide additional treatment options for pain and anxiety, among other symptoms. The present article summarizes the initial development and description of a hospital-based massage therapy course at a Midwest medical center. Methods: A hospital-based massage therapy course was developed on the basis of clinical experience and knowledge from massage therapists working in the complex medical environment. This massage therapy course had three components in its educational experience: online learning, classroom study, and a 25-hr shadowing experience. The in-classroom study portion included an entire day in the simulation center. Results: The hospital-based massage therapy course addressed the educational needs of therapists transitioning to work with interdisciplinary medical teams and with patients who have complicated medical conditions. Feedback from students in the course indicated key learning opportunities and additional content that are needed to address the knowledge and skills necessary when providing massage therapy in a complex medical environment. Conclusions: The complexity of care in medical settings is increasing while the length of hospital stay is decreasing. For this reason, massage provided in the hospital requires more specialized training to work in these environments. This course provides an example initial step in how to address some of the educational needs of therapists who are transitioning to working in the complex medical environment. PMID

    Background Data from hospital-based registers and medical records offer valuable sources of information for clinical and epidemiological research purposes. However, conducting high-quality epidemiological research requires valid and complete data sources. Objective To assess completeness and validity of a hospital-based clinical register – the Obstetric Database – using a national register and medical records as references. Methods We assessed completeness of a hospital-based clinical register – the Obstetric Database – by linking data from all women registered in the Obstetric Database as having given birth in 2013 to the National Patient Register with coverage of all births in 2013. Validity of eleven selected indicators from the Obstetric Database was assessed using medical records as a golden standard. Using a random sample of 250 medical records, we calculated proportion of agreement, sensitivity, specificity, and positive and negative predictive values for each indicator. Two assessors independently reviewed medical records and inter-rater reliability was calculated as proportion of agreement and Cohen’s κ coefficient. Results We found 100% completeness of the Obstetric Database when compared to the Danish National Patient Register. Except for one delivery all 6,717 deliveries were present in both registers. Proportion of agreement between the Obstetric Database and medical records ranged from 91.1% to 99.6% for the eleven indicators. The validity measures ranged from 0.70 to 1.00 indicating high validity of the Obstetric Database. κ coefficients from the inter-rater reliability ranged from 0.71 to 1.00. Conclusion Completeness and validity of the Obstetric Database were found acceptable when using the National Patient Register and medical records as golden standards. The Obstetric Database therefore offers a valuable source for examining clinical, administrative, and research questions. PMID:26648757

    Introduction Hospital based delivery has been an expensive experience for poor households because of hidden costs which are usually unaccounted in hospital costs. The main aim of this study was to estimate the hidden costs of hospital based delivery and determine the factors associated with the hidden costs. Methods A hospital based cross-sectional study was conducted among 384 post-partum mothers with their husbands/house heads during the discharge time in Manipal Teaching Hospital and Western Regional Hospital, Pokhara, Nepal. A face to face interview with each respondent was conducted using a structured questionnaire. Hidden costs were calculated based on the price rate of the market during the time of the study. Results The total hidden costs for normal delivery and C-section delivery were 243.4 USD (US Dollar) and 321.6 USD respectively. Of the total maternity care expenditures; higher mean expenditures were found for food & drinking (53.07%), clothes (9.8%) and transport (7.3%). For postpartum women with their husband or house head, the total mean opportunity cost of “days of work loss” were 84.1 USD and 81.9 USD for normal delivery and C-section respectively. Factors such as literate mother (p = 0.007), employed house head (p = 0.011), monthly family income more than 25,000 NRs (Nepalese Rupees) (p = 0.014), private hospital as a place of delivery (p = 0.0001), C-section as a mode of delivery (p = 0.0001), longer duration (>5days) of stay in hospital (p = 0.0001), longer distance (>15km) from house to hospital (p = 0.0001) and longer travel time (>240 minutes) from house to hospital (p = 0.007) showed a significant association with the higher hidden costs (>25000 NRs). Conclusion Experiences of hidden costs on hospital based delivery and opportunity costs of days of work loss were found high. Several socio-demographic factors, delivery related factors (place and mode of delivery, length of stay, distance from hospital and travel time) were associated

    Background Both methadone- and buprenorphine-treated opioid-dependent patients frequently show cognitive deficits in attention, working memory, and verbal memory. However, no study has compared these patient groups with each other during early opioid substitution treatment (OST). Therefore, we investigated attention, working memory, and verbal memory of opioid-dependent patients within six weeks after the introduction of OST in a naturalistic setting and compared to those of healthy controls. Methods The sample included 16 methadone-, 17 buprenorphine/naloxone-treated patients, and 17 healthy controls matched for sex and age. In both groups buprenorphine was the main opioid of abuse during the recent month. Benzodiazepine codependence, recent use, and comedication were also common in both patient groups. Analysis of variance was used to study the overall group effect in each cognitive test. Pair-wise group comparisons were made, when appropriate Results Methadone-treated patients, as a group, had significantly slower simple reaction time (RT) compared to buprenorphine/naloxone-treated patients. In Go/NoGo RT methadone patients were significantly slower than controls. Both patient groups were significantly debilitated compared to controls in working memory and verbal list learning. Only methadone patients were inferior to controls in story recall. In simple RT and delayed story recall buprenorphine/naloxone patients with current benzodiazepine medication (n = 13) were superior to methadone patients with current benzodiazepine medication (n = 13). When methadone patients were divided into two groups according to their mean dose, the patient group with a low dose (mean 40 mg, n = 8) showed significantly faster simple RT than the high dose group (mean 67 mg, n = 8). Conclusion Deficits in attention may only be present in methadone-treated early phase OST patients and may be dose-dependent. Working memory deficit is common in both patient groups.

    Background: Substance dependence disorder is a psychiatric disorders with different factors that influence its nature, severity, outcome, and treatment options. Objectives: This study evaluates the effectiveness of Acceptance-Commitment Therapy (ACT) to decrease anxiety and depression in patients with opioid dependencies who are undergoing methadone maintenance treatment (MMT). Materials and Methods: The present study was done in Mashhad from 2011-2012. Twenty-eight patients (18-50 yr) with opioid dependency who were on MMT were selected using purposive sampling and were divided equally between case and control groups. The case group received 8 sessions of individual psychotherapy with ACT. The level of depression and anxiety of these patients were measured using the Beck Depression Inventory-II and Beck Anxiety Inventory before the initiation of ACT as a pretest, 2 weeks after the termination of ACT as the posttest, and 3-months after the termination as a follow-up. The collected data was analyzed with SPSS (ver. 20) using χ2, paired t-test, ANOVA, and MANOVA. Results: The pretest-posttest-follow up of anxiety showed no significant differences between the two groups (P = 0.05); however, the case group had lower depression scores in the posttest and follow-up than the control group (P = 0.04). Evaluating the results of the case group revealed that depression significantly decreased in the posttest group when compared to the pretest (P = 0.01) and there were no significant decreases in the follow up compared to the pretest (P = 0.34). Conclusion: Short-term ACT for opioid dependent patients on MMT are not associated with a significant decrease in the level of anxiety; however, it is associated with a significant decrease in the level of depression. Nonetheless, this reduction was not maintained long term. PMID:26251660

    Background and aims Although an increasing number of children are born to mothers in opioid maintenance therapy (OMT), little is known about the long-term effects of these opioids. Previous studies suggest an association between prenatal OMT exposure and difficulties in eye movement control. Also, the effects of tobacco smoking on eye movements have been reported. The present study examined the influence of eye movements, i.e. smooth pursuit, on visuomotor capabilities in children of smoking mothers in OMT. Design The study comprised a 2 (OMT versus contrast group) × 2 (slow versus fast smooth pursuit) between-subject factorial design. Setting The cognitive developmental research unit at the University of Oslo, Norway. Participants Participants were 26 4-year-old children of tobacco-smoking women in OMT and 23 non-exposed 4-year-old children, with non-smoking mothers, matched by gender and age. Measurement Eye movements and smooth pursuit were recorded using a Tobii 1750 eyetracker. Visuomotor functions were examined by Bender test. Findings The OMT group tracked slowly moving objects with smooth pursuit in a similar manner to their non-exposed peers. When fast smooth pursuit was measured, the OMT group of children tracked the object more slowly than the contrast group, P = 0.02, ηp2 = 0.11. A regression analysis showed that fast smooth pursuit predicted children’s performance on a visuomotor task, R2 = 0.37. Conclusion Impaired eye-tracking skills in 4-year-old children exposed to methadone or buprenorphine and tobacco prenatally could inhibit the development of some cognitive functions in later life.

    Significant proportions of opiate-dependent persons entering methadone treatment are also addicted to cocaine and continue to use cocaine during treatment. One standard response to cocaine use has been inpatient detoxification. This study examined the effectiveness of this procedure by comparing pre- and posttreatment urine toxicologies for methadone patients who had been hospitalized for cocaine withdrawal. The results showed a negligible effect on cocaine abstinence (less than 1 out of 10 patients abstinent 12 weeks after detox) and a modest reduction in the frequency of cocaine use (one-quarter decline in urine tests positive after 12 weeks). These findings raise serious doubts about the cost-effectiveness of inpatient cocaine detoxification. Better strategies need to be implemented to enhance the chances of remaining abstinent once detoxified. PMID:9219143

    The fragile X-associated tremor ataxia syndrome (FXTAS) is caused by the premutation in FMR1 gene. Recent reports of environmental toxins appear to worsen the progression of FXTAS. Here we present a case of male adult with FXTAS and a long history of methadone use. The patient shows a faster progression in both symptoms of disease and MRI changes compared to what is typically seen in FXTAS. There has been no research regarding the role of narcotics in onset, progression, and severity of FXTAS symptoms. However, research has shown that narcotics can have a negative impact on several neurodegenerative diseases, and we hypothesize that in this particular case, methadone may have contributed to a faster progression of FXTAS as well as exacerbating white matter disease through RNA toxicity seen in premutation carriers.

    Perioperative management of patients receiving opioid addiction therapy presents a unique challenge for the anesthesiologist. The goal of pain management in this patient population is to effectively manage postoperative pain, to improve patient satisfaction and outcomes, and to reduce the cost of health care. Multimodal analgesics, including nonsteroid anti-inflammatory drugs, intravenous acetaminophen, gabapentanoid agents, and low-dose ketamine infusions, have been used to improve postoperative pain and to reduce postoperative opioid use. Patients on long-term opioid management therapy with methadone and buprenorphine require special considerations. Recommendations and options for treating postoperative pain in patients on methadone and buprenorphine are outlined below. Other postoperative pain management options include patient-controlled analgesia, intravenous, and transdermal, in addition to neuraxial and regional anesthesia techniques. Special patient populations include the parturient on long-term opioid therapy. Recommendations for use of opioids in these patients during labor and delivery and in the postpartum period are discussed. PMID:26879874

    Postmortem redistribution (PMR) refers to the site- and time-related blood drug concentration variations after death. We compared central blood (cardiac and subclavian) with peripheral blood (femoral and popliteal) concentrations of diazepam, methadone, and morphine. To our knowledge, popliteal blood has never been compared with other sites. Intracardiac blood (ICB), subclavian blood (SB), femoral blood (FB), and popliteal blood (PB) were sampled in 30 cases. To assess PMR, mean concentrations and ratios were compared. Influence of postmortem interval on mean ratios was also assessed. Results show that popliteal mean concentrations were lower than those for other sites for all three drugs, even lower than femoral blood; mean ratios suggested that the popliteal site was less subject to PMR, and estimated postmortem interval did not influence ratios except for diazepam and methadone FB/PB. In conclusion, our study is the first to explore the popliteal site and suggests that popliteal blood is less prone to postmortem redistribution. PMID:27364283

    Mothering and methadone can occur together with the right resources and support. Methadone mothers need to be seen in the context of their social risks and environment. Societal attitudes, social capital, and other contextual variables can be changed through policy. The purpose of this article is to describe the contextual risks experienced by drug abusing mothers in order to direct further research and policy changes that protect their children. Research has focused on biological or genetic determinants, but now social risks and environmental factors are shaping current literature about substance abuse in pregnancy. Significant risk factors, taken from the literature, are detailed, such as intimate partner violence and mental health co-morbidities. Racial differences and the effect of place on pregnant substance abusers are also discussed. Policy recommendations address the barriers substance abusing women face in their journey toward a healthy pregnancy. PMID:24066650

    Rationale Acute doses of buprenorphine can precipitate withdrawal in opioid dependent persons. The likelihood of this withdrawal increases as a function of the level of physical dependence. Objectives To test the acute effects of sublingual buprenorphine/naloxone tablets in volunteers with a higher level of physical dependence. The goal was to identify a dose that would precipitate withdrawal (Phase 1), then determine if withdrawal could be attenuated by splitting this dose (Phase 2). Methods Residential laboratory study; subjects (N=16) maintained on 100 mg per day of methadone. Phase 1: Randomized, double blind, triple dummy, within subject study. Conditions were sublingual buprenorphine/naloxone (4/1, 8/2, 16/4, 32/8 mg), intramuscular naloxone (0.2 mg), oral methadone (100 mg), or placebo. Medication conditions were randomized, but buprenorphine/naloxone doses were ascending within the randomization. Phase 2: Conditions were methadone, placebo, naloxone, 100% of the buprenorphine/naloxone dose that precipitated withdrawal in Phase 1 (full dose), and 50% of this dose administered twice in a session (split dose). Analyses covaried by trough methadone serum levels. Results Six subjects did not complete the study. Of the ten who completed, three tolerated up to 32/8 mg of buprenorphine/naloxone without evidence of precipitated withdrawal. For the seven completing both phases, split doses generally produced less precipitated withdrawal compared to full doses. Conclusions There is considerable between subject variability in sensitivity to buprenorphine's antagonist effects. Low, repeated doses of buprenorphine/naloxone (e.g., 2/0.5 mg) may be an effective mechanism for safely dosing this medication in persons with higher levels of physical dependence. PMID:17517480

    Topiramate is being investigated as a potential pharmacotherapy for the treatment of addictive disorders. However, its cognitive side effects raise concerns about its use, especially in populations with cognitive impairment, such as persons with chronic substance use disorders. This study investigated the topiramate's cognitive effects in individuals dually dependent on cocaine and opioids as part of a double-blind, randomized, controlled trial of topiramate for the cocaine dependence treatment. Following five weeks of stabilization on daily oral methadone (M=96 mg), participants were randomized to topiramate (n=18) or placebo (n=22). Cognitive testing took place at two time points: study weeks 4-5 to assess baseline performance and 10-13 weeks later to assess performance during stable dosing (300 mg topiramate or placebo). All participants were maintained on methadone at both testing times, and testing occurred two hours after the daily methadone plus topiramate/placebo administration. The topiramate and placebo groups did not differ on sex, level of education, premorbid intelligence, methadone dose, or illicit drug use. Topiramate slowed psychomotor and information processing speed, worsened divided attention, reduced n-back working memory accuracy, and increased the false alarm rate in recognition memory. Topiramate had no effects on visual processing, other measures of psychomotor function, risk-taking, self-control, Sternberg working memory, free recall, and metamemory. These findings indicate that topiramate may cause cognitive impairment in this population. This effect may limit its acceptability and use as a treatment in individuals with chronic opiate and cocaine use disorders, among whom pre-existing cognitive impairments are common. PMID:25365653

    We evaluated a comprehensive hospital-based infant safe sleep education program on parental education and safe sleep behaviors in the home using a cross-sectional survey of new parents at hospital discharge (HD) and 4-month follow-up (F/U). Knowledge and practices of infant safe sleep were compared to the National Infant Sleep Position Study benchmark. There were 1092 HD and 490 F/U surveys. Supine sleep knowledge was 99.8% at HD; 94.8% of families planned to always use this position. At F/U, 97.3% retained supine knowledge, and 84.9% maintained this position exclusively (P < .01). Knowledge of crib as safest surface was 99.8% at HD and 99.5% F/U. Use in the parents' room fell to 91.9% (HD) and 68.2% (F/U). Compared to the National Infant Sleep Position Study, the F/U group was more likely to use supine positioning and a bassinette or crib. Reinforcing the infant sleep safety message through intensive hospital-based education improves parental compliance with sudden infant death syndrome risk reduction guidelines. PMID:25670685

    Hospital-based nurse educators are in a prime position to mentor future nurse leaders; however, they need to first develop their own leadership practices. The goal was to establish a learning community where hospital-based nurse educators could develop their own nursing leadership practices within an online environment that included teaching, cognitive, and social presence. Using a pretest/posttest-only nonexperimental design, 35 nurse educators from three Canadian provinces engaged in a 12-week online learning community via a wiki where they learned about exemplary leadership practices and then shared stories about their own leadership practices. Nurse educators significantly increased their own perceived leadership practices after participation in the online community, and teaching, cognitive, and social presence was determined to be present in the online community. It was concluded that leadership development can be enhanced in an online learning community using a structured curriculum, multimedia presentations, and the sharing and analysis of leadership stories. Educators who participated should now be better equipped to role model exemplary leadership practices and mentor our nurse leaders of the future. PMID:24256766

    This scoping review provides current global understanding of the rapidly evolving nurse practitioner role within hospital settings, and considers the level of understanding of its enactment within interprofessional teamwork. Arksey and O'Malley's framework was used to explore recent primary research, reviews, and gray literature in two ways. First, hospital-based nurse practitioner literature was mapped to country of origin, and thematically summarized. Second, clearly developed and consistently defined key interprofessional concepts were identified in the interprofessional literature then conceptually mapped to the nurse practitioner studies by their operationalization. The nurse practitioner review located 103 abstracts. Twenty-nine, originating from four countries, met the inclusion criteria. The interprofessional concept review identified a total of 137 relevant abstracts, however, only ten met the inclusion criteria. Understanding the nurse practitioner role within hospital teams remains limited due to a small number of countries producing evidence, the lack of nurse practitioner role title standardization hindering consistent knowledgebase development, and limited application and inconsistent operationalization of concepts within nurse practitioner research. Research focused on role enactment is needed to understand the uniqueness of the hospital-based nurse practitioner role. PMID:24330003

    The aim of this study was to measure the temporal effects of intramuscular methadone administration on the minimum anesthetic concentration (MAC) of isoflurane in hens, and to evaluate the effects of the isoflurane-methadone combination on heart rate and rhythm, blood pressure and ventilation. Thirteen healthy adult hens weighing 1.7 ± 0.2 kg were used. The MAC of isoflurane was determined in each individual using the bracketing method. Subsequently, the reduction in isoflurane MAC produced by methadone (3 or 6 mg kg-1, IM) was determined by the up-and-down method. Stimulation was applied at 15 and 30 minutes, and at 45 minutes if the bird had not moved at 30 minutes. Isoflurane MAC reduction was calculated at each time point using logistic regression. After a washout period, birds were anesthetized with isoflurane and methadone, 6 mg kg-1 IM was administered. Heart rate and rhythm, respiratory rate, blood gas values and invasive blood pressure were measured at 1.0 and 0.7 isoflurane MAC, and during 45 minutes after administration of methadone once birds were anesthetized with 0.7 isoflurane MAC. Fifteen minutes after administration of 3 mg kg-1 of methadone, isoflurane MAC was reduced by 2 (-9 to 13)% [logistic regression estimate (95% Wald confidence interval)]. Administration of 6 mg kg-1 of methadone decreased isoflurane MAC by 29 (11 to 46)%, 27 (-3 to 56)% and 10 (-8 to 28)% after 15, 30 and 45 minutes, respectively. Methadone (6 mg kg-1) induced atrioventricular block in three animals and ventricular premature contractions in two. Methadone caused an increase in arterial blood pressure and arterial partial pressure of carbon dioxide, while heart rate and pH decreased. Methadone, 6 mg kg-1 IM significantly reduced isoflurane MAC by 30% in hens 15 minutes after administration. At this dose, methadone caused mild respiratory acidosis and increase in systemic blood pressure. PMID:27018890

  4. Patterns of non-compliant buprenorphine, levomethadone, and methadone use among opioid dependent persons in treatment

    2014-01-01

    Background The non-compliant use of opioid substitution treatment (OST) medicines is widespread and well-documented. However, less is known about characteristics of non-compliant OST medicine use and the factors that predict it. The two main goals of this study are to compare characteristics of non-compliant levomethadone, methadone, and buprenorphine use and to explore factors that may differentially predict it among opioid dependent persons in treatment. Methods Data from 595 opioid dependent patients with non-compliant OST medicine use were analyzed. Characteristics of use between substances were compared using chi-squared tests and predictive factors were explored through multinomial logistic regressions. Results Non-compliant levomethadone and methadone use was characterized by more frequent parallel consumption of other psychoactive substances and intravenous use, whereas buprenorphine was more often procured without a prescription. Regarding predictive factors, methadone was perceived to relieve withdrawal symptoms better than buprenorphine and levomethadone was perceived as being better at modulating the effects of other substances and worst at enhancing mood. Conclusions Patterns of non-compliant use differ according to OST medicine. These patterns are considered with the reduction of non-compliant use and the improvement of treatment in mind.

    This study examined cannabinoid-opioid interactions within the same subjects on measures of discrimination, antinociception, horizontal locomotion, and catalepsy. Male Sprague-Dawley rats were trained to discriminate Δ(9)-tetrahydrocannabinol (THC, 3 mg/kg) from vehicle. THC alone (0.32-10 mg/kg) dose-dependently increased THC-appropriate lever responding and decreased response rate. THC alone also produced paw pressure antinociception and decreased locomotor activity, but did not produce catalepsy. Methadone (0.32-5.6 mg/kg) and naltrexone (0.32-3.2 mg/kg) alone produced low THC-appropriate lever responding up to doses that decreased response rate. When combined with THC, methadone (1.0 mg/kg) flattened the THC discrimination curve, but did not affect antinociceptive or motoric effects of THC. Naltrexone did not alter any effects of THC. In rats that were not trained to discriminate THC from vehicle, 1.0 mg/kg methadone did enhance THC antinociception. These results suggest that μ-opioid receptor agonists can disrupt the discriminative stimulus effects of cannabinoids while not significantly altering their antinociceptive or motoric effects, in chronically drug-exposed subjects. Further research is required to determine whether opioid enhancement of cannabinoid antinociception is limited to acute exposure, or simply requires higher doses in chronically drug-exposed subjects.

  6. Do methadone and buprenorphine have the same impact on psychopathological symptoms of heroin addicts?

    PubMed Central

    2011-01-01

    Background The idea that the impact of opioid agonist treatment is influenced by the psychopathological profile of heroin addicts has not yet been investigated, and is based on the concept of a specific therapeutic action displayed by opioid agents on psychopathological symptoms. In the present report we compared the effects of buprenorphine and methadone on the psychopathological symptoms of 213 patients (106 on buprenorphine and 107 on methadone) in a follow-up study lasting 12 months. Methods Drug addiction history was collected by means of the Drug Addiction History Rating Scale (DAH-RS) and psychopathological features were collected by means of the Symptom Checklist-90 (SCL-90), using a special five-factor solution. Toxicological urinalyses were carried out for each patient during the treatment period. Results No statistically significant differences were detected in psychopathological symptoms, including 'worthlessness-being trapped', 'somatization', and 'panic-anxiety'. Methadone proved to be more effective on patients characterized by 'sensitivity-psychoticism', whereas buprenorphine was more effective on patients displaying a 'violence-suicide' symptomatology. Conclusions Heroin-dependent patients with psychiatric comorbidities may benefit from opioid agonist treatment not only because it targets their addictive problem, but also, precisely due to this, because it is effective against their mental disorder too.

    This study evaluated whether acepromazine or methadone reduced behavioral parameters, overall excitement, and activity associated with midazolam administration to healthy dogs. Dogs received midazolam (M) alone [M: 0.25 mg/kg body weight (BW)] or with methadone (MM) (MM: 0.75 mg/kg BW) or acepromazine (MA) (MA: 0.03 mg/kg BW) or saline (S) solution alone, all intramuscularly. Two blinded observers evaluated behavioral parameters using video recordings 30 min before and after injection of drugs. Accelerometery was used to evaluate “total activity counts” (TAC) at baseline and post-treatment. Post-treatment excitement scores were significantly higher in M and MA compared to baseline, M and MM compared to S, and M compared to MA. Behavioral parameters showed significantly higher proportions of “pacing” post-treatment in all groups receiving midazolam, and “restlessness,” “chewing/licking,” and “sniffing” in M. No significant differences were found for TAC at baseline and post-treatment. Midazolam-induced paradoxical behavioral changes (excitation, panting, pacing, restlessness, licking/chewing, and vocalization) were not prevented by acepromazine or methadone in healthy dogs.

    The current literature shows that the offspring of female rats exposed to methadone or ethanol display similar neurochemical and neurobehavioral alterations, and suggests that these drugs may be operating through a common mechanism. If this hypothesis is true, their effect on the endogenous opioid systems should be qualitatively similar. In this study virgin females were treated with methadone or 10% ethanol oral solution starting prior to conception and continued throughout gestation. When the offspring had reached 15 or 30 days of age they were sacrificed, the brain was removed and prepared for opioid receptor binding studies. ({sup 3}H)DAGO and ({sup 3}H)DADLE were used as ligands for the mu and delta receptors, respectively. These studies show significant treatment-related differences in both the number of mu and delta binding sites as well as in apparent receptor affinity. Significant sex- and age-related differences between treatments were also observed. These data show that methadone and ethanol, while manifesting some similar neurochemical and behavioral effects, have unique effects on opioid receptor binding, suggesting that they may be acting by different mechanisms.

    A validated method for quantifying methadone, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, cocaine, benzoylecgonine, 6-acetylmorphine, morphine, and codeine in human placenta by liquid chromatography–ion trap mass spectrometry is described. Specimens (1 g) were homogenized and subjected to solid-phase extraction. Chromatographic separation was performed on a Synergi Polar RP column with a gradient of 0.1% formic acid and acetonitrile. The method was linear from 10 to 2000 ng/g for methadone and 2.5 to 500 ng/g for other analytes. Limits of detection were 0.25–2.5 ng/g, imprecisions < 9.1%CV, analytical recoveries 84.4–113.3%, extraction efficiencies > 46%, matrix effects −8.0–129.9%, and process efficiencies 24.2–201.0%. Method applicability was demonstrated by analysis of five placenta specimens from opioid-dependent women receiving methadone pharmacotherapy, with methadone doses ranging from 65 to 95 mg on the day of delivery. These are the first data on placenta concentrations of methadone and metabolites after controlled drug administration. Detection of other common drugs of abuse in placenta will also improve our knowledge of the usefulness of this matrix for detecting in utero drug exposure and studying disposition of drugs in the maternal-fetal dyad.

    The study aimed to identify similarities and differences among ketamine, methadone users, and non-drug-using controls, on impulsivity, antisocial personality, and related cognitive abilities. A case-control observational design was used to compare the impulsivity and cognitive function of ketamine users (n = 51), methadone users (n=59), and controls (n=60). Antisocial personality traits and emotion states were also measured. One-way ANOVAs and planned post hoc pair-wise tests were used to analyze the data. Compared to non-drug-using controls, ketamine and methadone users had elevated scores on BIS and Pd scale of the MMPI, poorer performance on 2-back task, Stop-signal task, and Stroop test. Ketamine users performed the worst in the 2-back accuracy and Stop miss rate compared to methadone users and controls. There were no significant differences between the groups on the Iowa Gambling Task. Ketamine users did not show deficits in decision-making but exhibited strong impulsivity, antisocial personality, and poor response inhibition and working memory at levels similar to methadone users. These deficits may reflect vulnerability to addiction. This suggests that future treatment programs for ketamine users could address drug users' impulsive cognition and psychopathic deviance.

    Hospital chaplaincy and spiritual care services are important to patients' medical care and well-being; however, little is known about healthcare providers' experiences receiving spiritual support. A phenomenological study examined the shared experience of spiritual care between hospital chaplains and hospital-based healthcare providers (HBHPs). Six distinct themes emerged from the in-depth interviews: Awareness of chaplain availability, chaplains focus on building relationships with providers and staff, chaplains are integrated in varying degrees on certain hospital units, chaplains meet providers' personal and professional needs, providers appreciate chaplains, and barriers to expanding hospital chaplains' services. While HBHPs appreciated the care received and were able to provide better patient care as a result, participants reported that administrators may not recognize the true value of the care provided. Implications from this study are applied to hospital chaplaincy clinical, research, and training opportunities. PMID:26207904

    Recent developments in linac technology have led to the design of a hospital-based proton linac for fast neutron therapy. The 180 microamp average current allows beam to be diverted for radioisotope production during treatments while maintaining an acceptable dose rate. During dedicated operation, dose rates greater than 280 neutron rads per minute are achievable at depth, DMAX = 1.6 cm with source to axis distance, SAD = 190 cm. Maximum machine energy is 70 MeV and several intermediate energies are available for optimizing production of isotopes for Positron Emission Tomography and other medical applications. The linac can be used to produce a horizontal or a gantry can be added to the downstream end of the linac for conventional patient positioning. The 70 MeV protons can also be used for proton therapy for ocular melanomas. 17 refs., 1 fig., 1 tab.

    Background Psoriasis vulgaris is a chronic inflammatory skin disease with an immune-genetic background. It has been reported as an independent risk factor for coronary heart disease (CHD) in the United States and Europe. The purpose of this study was to investigate the association between psoriasis and CHD in a hospital-based population in Japan. Methods For 113,065 in-hospital and clinic patients at our institution between January 1, 2011 and January 1, 2013, the diagnostic International Classification of Diseases (ICD)-10 codes for CHD, hypertension, dyslipidemia, diabetes, and psoriasis vulgaris were extracted using the medical accounting system and electronic medical record, and were analyzed. Results The prevalence of CHD (n = 5,167, 4.5%), hypertension (n = 16,476, 14.5%), dyslipidemia (n = 9,236, 8.1%), diabetes mellitus (n = 11,555, 10.2%), and psoriasis vulgaris (n = 1,197, 1.1%) were identified. The prevalence of CHD in patients with hypertension, dyslipidemia, diabetes, and psoriasis vulgaris were 21.3%, 22.2%, 21.1%, and 9.0%, respectively. In 1,197 psoriasis patients, those with CHD were older, more likely to be male, and had more number of the diseases surveyed by ICD-10 codes. Multivariate analysis showed that psoriasis vulgaris was an independent associated factor for CHD (adjusted odds ratio [OR]: 1.27; 95% confidence interval [CI]: 1.01–1.58; p = 0.0404) along with hypertension (adjusted OR: 7.78; 95% CI: 7.25–8.36; p < 0.0001), dyslipidemia (adjusted OR: 2.35; 95% CI: 2.19–2.52; p < 0.0001), and diabetes (adjusted OR: 2.86; 95% CI: 2.67–3.06; p < 0.0001). Conclusion Psoriasis vulgaris was independently associated with CHD in a hospital-based population in Japan. PMID:26910469

    Background: Very few hospital-based or population-based studies are published in the context to the epidemiologic profile of pediatric brain tumors (PBTs) in India and Indian subcontinent. Aim: To study the demographic and histopathologic profile of PBTs according to World Health Organization 2007 classification in a single tertiary health care center in India. Materials and Methods: Data regarding age, gender, topography, and histopathology of 76 pediatric patients (0–19 years) with brain tumors operated over a period of 24 months (January-2012 to December-2013) was collected retrospectively and analyzed using EpiInfo 7. Chi-square test and test of proportions (Z-test) were used wherever necessary. Results: PBTs were more common in males (55.3%) as compared to females (44.7%) with male to female ratio of 1.23:1. Mean age was 10.69 years. Frequency of tumors was higher in childhood age group (65.8%) when compared to adolescent age group (34.2%). The most common anatomical site was cerebellum (39.5%), followed by hemispheres (22.4%). Supratentorial tumors (52.6%) were predominant than infratentorial tumors (47.4%). Astrocytomas (40.8%) and embryonal tumors (29.0%) were the most common histological types almost contributing more than 2/3rd of all tumors. Craniopharyngiomas (11.8%) and ependymomas (6.6%) were the third and fourth most common tumors, respectively. Conclusion: Astrocytomas and medulloblastomas are the most common tumors among children and adolescents in our region, which needs special attention from the neurosurgical department of our institute. Demographic and histopathologic profile of cohort in the present study do not differ substantially from that found in other hospital-based and population-based studies except for slight higher frequency of craniopharyngiomas.

    OBJECTIVE: To study a novel surveillance system introduced in Mpumalanga Province, a rural area in the north-east of South Africa, in an attempt to address deficiencies in the system of notification for infectious conditions that have the potential for causing outbreaks. METHODS: Hospital-based infection control nurses in all of Mpumalanga's 32 public and private hospitals were trained to recognize, report, and respond to nine clinical syndromes that require immediate action. Sustainability of the system was assured through a schedule of regular training and networking, and by providing feedback to the nurses. The system was evaluated by formal review of hospital records, evidence of the effective containment of a cholera outbreak, and assessment of the speed and appropriateness of responses to other syndromes. FINDINGS: Rapid detection, reporting and response to six imported cholera cases resulted in effective containment, with only 19 proven secondary cholera cases, during the two-year review period. No secondary cases followed detection and prompt response to 14 patients with meningococcal disease. By the end of the first year of implementation, all facilities were providing weekly zero-reports on the nine syndromes before the designated time. Formal hospital record review for cases of acute flaccid paralysis endorsed the value of the system. CONCLUSION: The primary goal of an outbreak surveillance system is to ensure timely recognition of syndromes requiring an immediate response. Infection control nurses in Mpumalanga hospitals have excelled in timely weekly zero-reporting, participation at monthly training and feedback sessions, detection of priority clinical syndromes, and prompt appropriate response. This review provides support for the role of hospital-based nurses as valuable sentinel surveillance agents providing timely data for action. PMID:11217663

    ALMA is an interferometer composed of 66 independent systems, with specific maintenance requirements for each subsystem. To optimize the observation time and reduce downtime maintenance, requirements are very demanding. One subsystem with high maintenance efforts is cryogenics and vacuum. To organize the maintenance, the Cryogenic and Vacuum department is using and implementing different tools. These are monitoring and problem reporting systems and CMMS. This leads to different maintenance approaches: Preventive Maintenance, Corrective Maintenance and Condition Based Maintenance. In order to coordinate activities with other departments the preventive maintenance schedule is kept as flexible as systems allow. To cope with unavoidable failures, the team has to be prepared to work under any condition with the spares on time. Computerized maintenance management system (CMMS) will help to manage inventory control for reliable spare part handling, the correct record of work orders and traceability of maintenance activities. For an optimized approach the department is currently evaluating where preventive or condition based maintenance applies to comply with the individual system demand. Considering the change from maintenance contracts to in-house maintenance will help to minimize costs and increase availability of parts. Due to increased number of system and tasks the cryo team needs to grow. Training of all staff members is mandatory, in depth knowledge must be built up by doing complex maintenance activities in the Cryo group, use of advanced computerized metrology systems.

    Aim and objective: To describe the study design of a randomised controlled trial with the aim of comparing two different regimes for children with newly diagnosed type 1 diabetes; hospital-based care and hospital-based home care. Background: Procedures for hospital admission and sojourn in connection with diagnose vary greatly worldwide and the existing evidence is insufficient to allow for any conclusive determination of whether hospital-based or home-based care is the best alternative for most families. Comparative studies with adequate power and outcome measurements, as well as measurements of cost-effectiveness are needed. Design: The study design was based on the Medical Research Council framework for complex interventions. After two to three days with hospital-based care, children between the ages of 3 and 16 were randomised to receive either continued hospital-based care for a total of 1-2 weeks or hospital-based home care, which refers to specialist care in a home-based setting. The trial started in March 2008 at a University Hospital in Sweden and was closed in September 2011 when a sufficient number of children according to power calculation, were included. The primary outcome was the child’s metabolic control during the following two years. Secondary outcomes were set to evaluate the family and child situation as well as the organisation of care. Discussion: Childhood diabetes requires families and children to learn to perform multiple daily tasks. Even though intervention in health care is complex with several interacting components entailing practical and methodological difficulties, there is nonetheless, a need for randomised controlled trials in order to evaluate and develop better systems for the learning processes of families that can lead to long-term improvement in adherence and outcome.

    The aim of this study was to evaluate the effectiveness of opium tincture versus methadone syrup in the management of acute withdrawal syndrome in opium dependent patients during the detoxification period. In this double-blind randomized controlled study, a total of 74 adult male raw opium dependent patients were treated with opium tincture or methadone syrup 2 times daily for 5 consecutive days. Detoxification was initiated by tapered dose reductions to reach abstinence. At the end of the 10th day, the medications were discontinued. The Objective Opioid Withdrawal Scale was used to assess withdrawal symptoms every day. Significant decreases on the Objective Opioid Withdrawal Scale were found for both treatment methods during the study period (p < .0001). However, there was no significant difference between groups on the total Objective Opioid Withdrawal Scale, and adverse effects existed. Opium tincture can be considered as a potential substitute for methadone syrup for suppression of raw opium withdrawal symptoms, with minimal adverse effects. PMID:26566681

    Background: The objective of this study was to determine the effectiveness of MMT program among injecting drug users (IDUs) in Kota Bharu, Kelantan. Methods: The study was a retrospective study based on the records of injecting drug users (IDUs) involved in the MMT program from November 2005 to 31st Jan 2008, registered at the Psychiatric Clinic of Hospital Raja Perempuan Zainab II. Opiate Treatment Index (OTI) was used as the research instrument. Repeated measures ANCOVA was used to compare the mean scores during the entry period and after completing twelve months of MMT program after adjusted for age, marital status, and level of education. Results: A total of 117 file records were reviewed. There was significant reduction in the mean scores after 12 months of heroin Q score, HIV Risk-taking Behavior Scale and health scale after adjusted for age, marital status, and level of education. For Heroin Q score, mean difference was 2.01 (95% CI: 1.45, 2.56), for HIV Risk-taking Behavior Scale, mean difference was 7.64 (95% CI: 6.03, 9.26), and for health scale, mean difference was 5.35(95% CI: 3.90, 6.79). Conclusion: This study supports the evidence that MMT program is effective in treating heroin and opiate dependence. PMID:23613645

    Background This secondary analysis examined the impact of methadone initiated in prison on post-release HIV risk behaviors. The parent study was a three-group randomized clinical trial in which participants received drug abuse counseling in prison and were randomly assigned to: (1) passive referral to substance abuse treatment upon release; (2) guaranteed methadone treatment admission upon release; and (3) methadone in prison and guaranteed continuation of methadone upon release. Methods Participants were 211 adult males with pre-incarceration histories of opiate dependence. The AIDS Risk Assessment was administered at baseline (in prison) and at 1-, 3-, 6-, and 12-months post-release. Data were analyzed for the entire sample (N = 211) as well as the subsamples who reported injecting drugs in the 30 days prior to incarceration (n = 131) and who reported having unprotected sex in that time frame (n = 144) using generalized linear mixed model on an intent-to-treat basis. Results There were no significant changes in sex- or drug-risk by Condition over Time. There were significant Time and Condition main effects for the total sample as well as the injector subsample for drug-risk behaviors. There were no significant Condition main effects for HIV sex–risk behaviors, but there were significant Time main effects. Conclusions Methadone initiated in prison or immediately post-release is associated with reduced HIV drug-risk compared to counseling in prison without methadone and passive referral to treatment at release. Participation in several drug- and sex-risk behaviors also showed significant declines during the post-release time periods. PMID:22882399

    Medication-assisted treatment for opioid dependence is safe and effective, yet negative perceptions about methadone and buprenorphine may discourage patients from entering treatment. One source of information that may influence viewers' perceptions is television. We performed a content analysis of a popular reality television program on addiction treatment. Although many patients had histories of opioid use, there were no positive messages about methadone or buprenorphine. The two main messages were that they (1) are primarily drugs of abuse, and (2) not acceptable treatment options. These messages reinforce negative stereotypes and may perpetuate stigma. There were multiple missed opportunities to provide evidence-based information. PMID:22587811

    AIM: To examine effects of chronic methadone usage on bowel visualization, preparation, and repeat colonoscopy. METHODS: In-patient colonoscopy reports from October, 2004 to May, 2009 for methadone dependent (MD) patients were retrospectively evaluated and compared to matched opioid naive controls (C). Strict criteria were applied to exclude patients with risk factors known to cause constipation or gastric dysmotility. Colonoscopy reports of all eligible patients were analyzed for degree of bowel visualization, assessment of bowel preparation (good, fair, or poor), and whether a repeat colonoscopy was required. Bowel visualization was scored on a 4 point scale based on multiple prior studies: excellent = 1, good = 2, fair = 3, or poor = 4. Analysis of variance (ANOVA) and Pearson χ2 test were used for data analyses. Subgroup analysis included correlation between methadone dose and colonoscopy outcomes. All variables significantly differing between MD and C groups were included in both univariate and multivariate logistic regression analyses. P values were two sided, and < 0.05 were considered statistically significant. RESULTS: After applying exclusionary criteria, a total of 178 MD patients and 115 C patients underwent a colonoscopy during the designated study period. A total of 67 colonoscopy reports for MD patients and 72 for C were included for data analysis. Age and gender matched controls were randomly selected from this population to serve as controls in a numerically comparable group. The average age for MD patients was 52.2 ± 9.2 years (range: 32-72 years) years compared to 54.6 ± 15.5 years (range: 20-81 years) for C (P = 0.27). Sixty nine percent of patients in MD and 65% in C group were males (P = 0.67). When evaluating colonoscopy reports for bowel visualization, MD patients had significantly greater percentage of solid stool (i.e., poor visualization) compared to C (40.3% vs 6.9%, P < 0.001). Poor bowel preparation (35.8% vs 9.7%, P < 0.001) and

    Background The lack of methadone pharmacokinetic data in children and neonates restrains dosing to achieve the target concentration in these populations. A minimum effective analgesic concentration of methadone in opioid naïve adults is 0.058 mg.L−1, while no withdrawal symptoms were observed in neonates suffering opioid withdrawal if plasma concentrations of methadone were above 0.06 mg.L−1. The racemate of methadone which is commonly used in pediatric and anaesthetic care is metabolized to EDDP (2-ethylidine-1,5-dimethyl-3,3-diphenylpyrrolidine) and EMDP (2-ethyl-5-methyl-3,3-diphenylpyrroline). Methods Data from 4 studies (age 33 weeks PMA-15 years) were pooled (n=56) for compartment analysis using nonlinear mixed effects modeling. Parameter estimates were standardized to a 70 kg person using an allometric model approach. Investigation was made of the racemate and metabolite (EDDP and EMDP) dispositions. In addition, neonatal data (n=7) allowed further study of R and S enantiomer pharmacokinetics. Results A three-compartment linear disposition model best described the observed time-concentration profiles with additional compartments for metabolites. Population parameter estimates (between subject variability) were central volume (V1) 21.5 (29%) L.70kg−1, peripheral volumes of distribution V2 75.1 (23%) L.70kg−1, V3 484 (8%) L.70kg−1, clearance (CL) 9.45 (11%) L.h−1.70kg−1 and inter-compartment clearances Q2 325 (21%) L.h−1.70kg−1, Q3 136 (14%) L.h−1.70kg−1. EDDP formation clearance was 9.1 (11%) L.h−1.70kg−1, formation clearance of EMDP from EDDP 7.4 (63%) L.h−1.70kg−1, elimination clearance of EDDP was 40.9 (26%) L.h−1.70kg−1, and the rate constant for intermediate compartments 2.17 (43%) /h. Conclusions Current pharmacokinetic parameter estimates in children and neonates are similar to those reported in adults. There was no clearance maturation with age. Neonatal enantiomer clearances were similar to those described in adults

  6. Facilities maintenance handbook

    NASA Technical Reports Server (NTRS)

    1991-01-01

    This handbook is a guide for facilities maintenance managers. Its objective is to set minimum facilities maintenance standards. It also provides recommendations on how to meet the standards to ensure that NASA maintains its facilities in a manner that protects and preserves its investment in the facilities in a cost-effective manner while safely and efficiently performing its mission. This handbook implements NMI 8831.1, which states NASA facilities maintenance policy and assigns organizational responsibilities for the management of facilities maintenance activities on all properties under NASA jurisdiction. It is a reference for facilities maintenance managers, not a step-by-step procedural manual. Because of the differences in NASA Field Installation organizations, this handbook does not assume or recommend a typical facilities maintenance organization. Instead, it uses a systems approach to describe the functions that should be included in any facilities maintenance management system, regardless of its organizational structure. For documents referenced in the handbook, the most recent version of the documents is applicable. This handbook is divided into three parts: Part 1 specifies common definitions and facilities maintenance requirements and amplifies the policy requirements contained in NMI 8831. 1; Part 2 provides guidance on how to meet the requirements of Part 1, containing recommendations only; Part 3 contains general facilities maintenance information. One objective of this handbook is to fix commonality of facilities maintenance definitions among the Centers. This will permit the application of uniform measures of facilities conditions, of the relationship between current replacement value and maintenance resources required, and of the backlog of deferred facilities maintenance. The utilization of facilities maintenance system functions will allow the Centers to quantitatively define maintenance objectives in common terms, prepare work plans, and

    The purpose of this prospective nonrandomized study was to evaluate time spent at home, place of death and differences in sociodemographic and medical characteristics of patients, with cancer in palliative stage, receiving either hospital-based advanced home care (AHC), including 24-hour service by a multidisciplinary palliative care team or conventional hospital care (CC). Recruitment to the AHC group and to the study was a two-step procedure. The patients were assigned to either hospital-based AHC or CC according to their preferences. Following this, the patients were asked to participate in the study. Patients were eligible for the study if they had malignant disease, were older than 18 years and had a survival expectancy of 2-12 months. A total of 297 patients entered the study and 280 died during the study period of two and a half years, 117 in the AHC group and 163 in the CC group. Significantly more patients died at home in the AHC group (45%) compared with the CC group (10%). Preference for and referral to hospital-based AHC were not related to sociodemographic or medical characteristics. However, death at home was associated with living together with someone. Advanced hospital-based home care targeting seriously ill cancer patients with a wish to remain at home enable a substantial number of patients to die in the place they desire. PMID:15540666

    Hospital-based and community-based studies were conducted to understand the prevalence and mode of transmission of Cryptosporidium parvum infection in Surabaya, Indonesia. In both studies people with and without diarrhea were examined for oocysts. A community-based survey included questionnaires to a community and stool examination of cats. Questionnaires covered demographic information, health status, and hygienic indicators. In the hospital, C. parvum oocysts were found in 26 (2.8%) of 917 patients with diarrhea and 15 (1.4%) of 1,043 control patients. The most susceptible age was less than two years old. The prevalence was higher during the rainy season. A community-based study again showed that C. parvum oocysts were frequently detected in diarrhea samples (8.2%), exclusively during rainy season. Thirteen (2.4%) of 532 cats passed C. parvum oocysts. A multiple logistic regression model indicated that contact with cats, rain, flood, and crowded living conditions are significant risk factors for Cryptosporidium infection. PMID:9790442

    Purpose: Quality improvement programs in Europe have had a markedly beneficial effect on the processes and outcomes of rectal cancer care. The quality of rectal cancer care in the United States is not as well understood, and scalable quality improvement programs have not been developed. The purpose of this article is to describe the implementation of a hospital-based quality assessment program for rectal cancer, targeting both community and academic hospitals. Methods: We recruited 10 hospitals from a surgical quality improvement organization. Nurse reviewers were trained to abstract rectal cancer data from hospital medical records, and abstracts were assessed for accuracy. We conducted two surveys to assess the training program and limitations of the data abstraction. We validated data completeness and accuracy by comparing hospital medical record and tumor registry data. Results: Nine of 10 hospitals successfully performed abstractions with ≥ 90% accuracy. Experienced nurse reviewers were challenged by the technical details in operative and pathology reports. Although most variables had less than 10% missing data, outpatient testing information was lacking from some hospitals' inpatient records. This implementation project yielded a final quality assessment program consisting of 20 medical records variables and 11 tumor registry variables. Conclusion: An innovative program linking tumor registry data to quality-improvement data for rectal cancer quality assessment was successfully implemented in 10 hospitals. This data platform and training program can serve as a template for other organizations that are interested in assessing and improving the quality of rectal cancer care. PMID:24839288

    Introduction Co-infection of Japanese Encephalitis (JE) and Cysticercosis is attributed mainly to the common epidemiological features between the two diseases. Not much is known about the clinical implications of one infection over the other. Aim The study aimed at establishing whether JE-Cysticercosis co-infection is prevalent in the Upper Assam districts and to explore additional details about such co-infections both clinically and epidemiologically. Materials and Methods The present study was a retrospective cross-sectional hospital based study conducted between July 2013 and June 2014 and included 272 Acute Encephalitis Syndrome (AES) patients. Out of this, 137 JE positive and 135 non-JE Acute encephalitis patients were taken as cases and controls respectively. The diagnosis of JE and Cysticercosis was established by ELISA. Statistical Analysis EpiInfo ver. 7 was used for statistical analysis. Chi-square was used and p-value < 0.05 was considered to be statistically significant. Results The association of Cysticercosis with JE was found to be statistically significant (14.6%, p = 0.0019) in the cases with reference to the controls (3.7%). Moreover, the co-infections were found to be more common in case of adults (19.32%, p = 0.0360); with males having a greater odds (5.25, p = 0.0008) of harbouring the parasite as compared to females. Conclusion The study proves that the association of Cysticercosis and JE holds true in this region. PMID:27437215

    Recognizing the importance of the case manager as a system integrator, United Health Services, Inc. (UHS), a hospital-based health care system located in upstate New York, implemented several diverse case management models. Case managers were working in a variety of settings, often in isolation. It was determined that a system-wide case management education program would accomplish two goals: (a) provide all case managers within the UHS system with similar case management practice skills and language, and (b) provide an opportunity for case managers to meet, share role responsibilities and common case management issues, and use each other as resources. With input from leadership throughout the UHS system, a 4-week case management education program was developed and presented. Participants included multidisciplinary staff who had case management responsibilities within the system. Sessions were taught by UHS staff experts in a number of different disciplines. A teaching guide and manual were developed to supplement the didactic material. Feedback from the program was provided via written participant evaluation and follow-up discussions. PMID:8000326

    The objective is to identify factors associated with women's satisfaction towards the care provided by the health professionals during hospital assisted delivery and identify how those factors influence their general levels of satisfaction. The cohort hospital based study was carried out in connection with the Birth in Brazil research. 15,688 women were included, interviewed at home, through the phone, from March 2011 to February 2012. All the variables that compose the professional/pregnant woman relationship (waiting time, respect, privacy, clarity of explanations, possibility of asking questions and participating in the decisions) and schooling remained independently associated with general satisfaction towards delivery care, in the adjusted model. The white women assisted in the southeastern and southern regions of the country, by the private sector and with a companion present gave a better evaluation of the care provided. Women value the way in which they are assisted by the health professionals, and there are inequalities in the way they are treated based on skin color, geographic region and financial situation.

    Objectives. To compare home-based rehabilitation with the standard hospital rehabilitation in terms of improving knee joint mobility and recovery of muscle strength and function in patients after a total knee replacement. Materials and Methods. A non-randomised controlled trial was conducted. Seventy-eight patients with a prosthetic knee were included in the study and allocated to either a home-based or hospital-based rehabilitation programme. Treatment included various exercises to restore strength and joint mobility and to improve patients' functional capacity. The primary outcome of the trial was the treatment effectiveness measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results. The groups did not significantly differ in the leg side (right/left) or clinical characteristics (P > 0.05). After the intervention, both groups showed significant improvements (P < 0.001) from the baseline values in the level of pain (visual analogue scale), the range of flexion-extension motion and muscle strength, disability (Barthel and WOMAC indices), balance, and walking. Conclusions. This study reveals that the rehabilitation treatments offered either at home or in hospital settings are equally effective. PMID:25961017

    The Legislative Action Interest Group (LAIG) is a hospital-based health policy forum that engages nurses in exploring clinical implications of existing and pending health policies and regulations, while also creating a feedback loop to inform policy makers about the realities nursing practice and patient care. The LAIG is a collaborative effort between the hospital's Department of Nursing and Patient Care Services and the Office of Government Relations at an academic children's hospital. Nurses participating in the LAIG forums build a working knowledge of health policy and can articulate the practice realities for policy decision makers. Participants explore the political context of nursing and pediatric policies while learning about the state legislative process. Beyond the monthly meetings, members build policy advocacy skills and have testified at public hearings, met with state and federal legislators, and led tours for policy makers through the hospital. The LAIG model also benefits the government relations staff by providing time for them to discuss clinical implications of pending policies with nurses from practice settings in the hospital. Forum discussions enhance the ability of the hospital's lobbyists to articulate practice implications of health policy to lawmakers. This case study, describing the origin, structure, operations, and outcomes of the LAIG model, and has implications for nurses in hospitals and academic settings who are interested in engaging in policy work. Opportunities to research the sustainability, replicability, and patient-centered outcomes of LAIG forums represent future work needed to advance nursing's participation in policy. PMID:26880725

    Avoidance of dental care and neglect of oral health may occur in patients with inherited bleeding disorders because of concerns about perioperative and postoperative bleeding, but this is likely to result in the need for crisis care, and more complex and high-risk procedures. Most routine dental care in this special needs group can be safely managed in the general dental setting following consultation with the patient's haematologist and adherence to simple protocols. Many of the current protocols for dental treatment of patients with inherited bleeding disorders were devised many years ago and now need revision. There is increasing evidence that the amount of factor cover previously recommended for dental procedures can now be safely reduced or may no longer be required in many cases. There is still a need for close cooperation and discussion between the patient's haematologist and dental surgeon before any invasive treatment is performed. A group of hospital based dentists from centres where patients with inherited bleeding disorders are treated met and, after discussions, a management protocol for dental treatment was formulated.

    Successful implementation of universal patient education programs requires training large numbers of nursing staff in new content and procedures and maintaining fidelity to program standards. In preparation for statewide adoption of a hospital based universal education program, nursing staff at 85 hospitals and 1 birthing center in North Carolina received standardized training. This article describes the training program and reports findings from the process, outcome and impact evaluations of this training. Evaluation strategies were designed to query nurse satisfaction with training and course content; determine if training conveyed new information, and assess if nurses applied lessons from the training sessions to deliver the program as designed. Trainings were conducted during April 2008-February 2010. Evaluations were received from 4358 attendees. Information was obtained about training type, participants' perceptions of newness and usefulness of information and how the program compared to other education materials. Program fidelity data were collected using telephone surveys about compliance to delivery of teaching points and teaching behaviors. Results demonstrate high levels of satisfaction and perceptions of program utility as well as adherence to program model. These findings support the feasibility of implementing a universal patient education programs with strong uptake utilizing large scale systematic training programs. PMID:26341727

    To examine uptake of a novel emergency food system at five cancer clinics in New York City, hospital-based food pantries, and predictors of use, among low-income urban cancer patients. This is a nested cohort study of 351 patients who first visited the food pantries between October 3, 2011 and January 1, 2013. The main outcome was continued uptake of this food pantry intervention. Generalized estimating equation (GEE) statistical analysis was conducted to model predictors of pantry visit frequency. The median number of return visits in the 4 month period after a patient's initial visit was 2 and the mean was 3.25 (SD 3.07). The GEE model showed that younger patients used the pantry less, immigrant patients used the pantry more (than US-born), and prostate cancer and Stage IV cancer patients used the pantry more. Future long-term larger scale studies are needed to further assess the utilization, as well as the impact of food assistance programs such as the this one, on nutritional outcomes, cancer outcomes, comorbidities, and quality of life. Cancer patients most at risk should be taken into particular consideration. PMID:26070869

    2013-05-01

    A 52-year-old man with a medical history of intravenous drug abuse was admitted to our hospital with syncope due to torsades de pointes (TdP). Two days earlier, he had used methadone. The electrocardiogram showed a prolonged corrected QT interval (QTc) of 600 ms. Continuous telemetry observation showed multiple episodes of TdP. The patient was diagnosed with bradyarrhythmia-induced TdP with acquired long QT syndrome resulting from methadone use. The QTc normalised within 2 weeks after discontinuation of the methadone. In this case of a patient with opioid dependency, there is a reasonable risk of repeated methadone use. Therefore, implantable cardioverter defibrillator or pacemaker implantation is justified but risky because of possible infections when using intravenous drugs. Given the high mortality rates seen in untreated illicit opioid users, this patient needs an alternative pharmacological treatment. Buprenorphine is an opiate-receptor agonist associated with less QTc prolongation. The patient was referred to a rehab clinic and treated with an oral combination of buprenorphine and naloxone (Suboxone). During this therapy, his QTc remained normal. PMID:22020456

    The aims of this pilot study were: (a) to test the feasibility of prolonged exposure (PE) therapy conducted by a social worker staff on female patients in methadone program clinics who were survivors of child sexual abuse or rape and (b) to examine preliminary outcomes of PE on posttraumatic stress disorder (PTSD), depression, and illicit drug use at pre- and posttreatment, and up to 12-month follow-ups. Twelve female methadone patients who were survivors of child sexual abuse or rape diagnosed with PTSD were enrolled in 13-19 weekly individual PE sessions. Assessments were conducted at pre-, mid-, and posttreatment, as well as at 3, 6, and 12-month follow-ups. The treatment outcomes measures included PTSD symptoms, depressive symptoms, and illicit drug use. Ten of the 12 study patients completed treatment. PTSD and depressive symptoms showed significant reduction. No relapse to illicit drug use was detected. These preliminary results suggest that PE may be delivered by methadone social workers with successful outcomes. Further research should test the efficacy of PE among methadone patients in a randomized control trial with standard care as the control condition. PMID:26399489

    Objective Contingency management (CM) reduces cocaine use in methadone patients, but only about 50% of patients respond to CM interventions. This study evaluated whether increasing magnitudes of reinforcement will improve outcomes. Methods Cocaine-dependent methadone patients (N = 240) were randomized to one of four 12-week treatment conditions: usual care (UC), UC plus “standard” prize CM in which average expected prize earnings were about $300, UC plus high magnitude prize CM in which average expected prize earnings were about $900, or UC plus voucher CM with an expected maximum of about $900 in vouchers. Results All three CM conditions yielded significant reductions in cocaine use relative to UC, with effect sizes (d) ranging from 0.38 to 0.59. No differences were noted between CM conditions, with at least 55% of patients in each CM condition achieving one week or more of cocaine abstinence versus 35% in UC. During the 12 weeks after the intervention ended, CM increased time until relapse relative to UC, but the effects of CM were no longer significant at a 12-month follow-up. Conclusions Providing the standard magnitude of $300 in prizes was as effective as larger magnitude CM in cocaine-dependent methadone patients in this study. Given its strong evidence base and relatively low costs, standard magnitude prize CM should be considered for adoption in methadone clinics to encourage cocaine abstinence, but new methods need to be developed to sustain abstinence.

    Opioid substitution treatment (OST) is still controversial, despite positive results. The issue of diversion to the illicit drug market is a cornerstone in the criticism typically voiced against the treatment. Little research is available concerning how professionals who work in OST view the issue of diversion. In this article, we discuss existing ideas and attitudes toward diversion of methadone and buprenorphine among OST staff in Sweden. The article is based on semi-structured interviews with 25 professionals working in eight OST-programs in southern Sweden. Diversion was seen as a deleterious phenomenon by the interviewees. Three problematic aspects were highlighted: medical risks in the form of overdose fatalities and the recruitment of new opiate/opioid users; negative consequences for the legitimacy of OST; and moral objections, since diversion means that the patients remain in a criminal environment. However, positive aspects were also highlighted. Illicit methadone or buprenorphine is perceived as safer than heroin. In this way, diversion can fulfill a positive function; for instance, if there is a shortage of access to regular treatment. Patients who share their medication with opioid-dependent friends are seen as less culpable than those who sell to anyone for money. PMID:25364995

    Whereas research has suggested that drug-involved men are at disproportionately high risk of engaging in transmission risk behaviors for HIV and of perpetrating intimate partner violence (IPV) against women, only a few cross-sectional studies have examined the relationship between IPV and HIV/sexually transmitted infection (STI) transmission risks among heterosexual, drug-involved men. This study builds on previous cross-sectional research by using a longitudinal design to examine the temporal relationships between perpetration of IPV and different HIV/STI transmission risks among a random sample of 356 men on methadone assessed at baseline (wave 1), 6 months (wave 2), and 12 months (wave 3). The findings indicate that (1) perpetration of IPV in the past 6 months at wave 1 was associated with having more than one intimate partner, buying sex, and sexual coercion at subsequent waves and that (2) noncondom use, injecting drugs, and sexual coercion at wave 1 were associated with subsequent IPV. The temporal relationships between perpetration of IPV and HIV risks found in this study underscore the need for HIV prevention interventions targeting men on methadone to consider IPV and HIV risks as cooccurring problems.

    Homelessness is a primary concern for community health. Scientific literature on homelessness is wide ranging and diverse. One opportunity to add to existing literature is the development and testing of affordable, easily implemented methods for measuring the impact of homeless on the healthcare system. Such methodological approaches rely on the strengths in a multidisciplinary approach, including providers, both healthcare and homeless services and applied clinical researchers. This paper is a proof of concept for a methodology which is easily adaptable nationwide, given the mandated implementation of homeless management information systems in the United States and other countries; medical billing systems by hospitals; and research methods of researchers. Adaptation is independent of geographic region, budget restraints, specific agency skill sets, and many other factors that impact the application of a consistent methodological science based approach to assess and address homelessness. We conducted a secondary data analysis merging data from homeless utilization and hospital case based data. These data detailed care utilization among homeless persons in a small, Appalachian city in the United States. In our sample of 269 persons who received at least one hospital based service and one homeless service between July 1, 2012 and June 30, 2013, the total billed costs were $5,979,463 with 10 people costing more than one-third ($1,957,469) of the total. Those persons were primarily men, living in an emergency shelter, with pre-existing disabling conditions. We theorize that targeted services, including Housing First, would be an effective intervention. This is proposed in a future study. PMID:24894404

    Today, hospitals are involved extensively in social marketing and promotional activities. Recently, investigators from the Centers for Disease Control and Prevention (CDC) estimated that routine testing of hospital patients for human immunodeficiency virus (HIV) could identify more than 100,000 patients with previously unrecognized HIV infections. Several issues are assessed in this paper. These include hospital support for voluntary HIV testing and AIDS education and the impact that treating AIDS patients has on the hospital's image. Also tested is the hypothesis that certain hospitals, such as for-profit institutions and those outside the AIDS epicenters, would be less supportive of hospital-based AIDS intervention strategies. To assess these issues, a national random sample of 193 executives in charge of hospital marketing and public relations were surveyed between December 1992 and January 1993. The survey was part of an ongoing annual survey of hospitals and included questions about AIDS, health education, marketing, patient satisfaction, and hospital planning. Altogether, 12.4 percent of executives indicated their hospital had a reputation for treating AIDS patients. Among hospitals without an AIDS reputation, 34.1 percent believed developing one would be harmful to the hospital's image, in contrast to none in hospitals that had such a reputation (chi 2 = 11.676, df = 1, P = .0006). Although 16.6 percent did not know if large-scale HIV testing should be implemented, a near majority (47.7 percent) expressed some support. In addition, 15 percent reported that HIV-positive physicians on the hospital's medical staff should not be allowed to practice medicine, but 32.1 percent indicated that they should.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7638335

    Injuries account for a large burden of mortality and morbidity in the State of Qatar. No comprehensive study has been conducted on all types of injuries in the State of Qatar. The objective of this study was to determine the trend in the number, incidence and pattern of injuries in the State of Qatar. This hospital-based study is a retrospective analysis of 53,366 patients treated at the accident and emergency and trauma centres for injuries during the period from 2006 to 2010. Injuries were determined according to the ICD 10 criteria. The details of the entire trauma patients who were involved in occupational/domestic injuries were extracted from the database of the Emergency Medical Services (EMS), Hamad Medical Corporation. Our results demonstrated that the rates of injury remained relatively stable in the State of Qatar over the five-year period. Those most at risk of injury were non-Qatari males who were below 30 years. Road traffic accidents (RTA) (36.7%) followed by falls causing back injuries (11.0%) were the most common types of injuries during the period. Most of the injuries occurred at the head for both males (17.7%) and females (13.5%); this was consistently the case across all of the age groups. The greatest proportion of RTA (21.2%), industrial machinery injuries (16.4%), construction injuries (15.5%), recreational sporting injuries (20.5%) and beach/sea/ocean injuries (15.0%) resulted in head injuries. Intervention efforts need to be aimed at reducing occupational injuries, RTA injuries and work-related hazards in the State of Qatar. PMID:22455450

    Background: Viral hepatitis is a major public health problem throughout the world. It is the inflammation of the liver due to the infection of any of the five main hepatic viruses A to E and it affects the liver through different modes of transmission. This study mainly aims at the frequency and distribution of viral hepatitis based on age and sex during a time period of 5 years. Materials and Methods: This is a hospital-based retrospective study of 5 years at a tertiary level hospital in Kerala state in India. Medical records department of the hospital follow the guidelines of International Classification of Diseases-10 for coding the diseases. The data on frequency and distribution of viral hepatitis based on age and sex during a period of 5 years from April 2005 to March 2010 were collected and analyzed and ‘z’ test was used for finding out the difference in proportions. Result: Out of 818 cases, 76.03% were males and 23.96% were females. The preponderance of males was apparent in all types of viral hepatitis infection. The high risk groups were the adults in the age group of 20-39 years. The main cause in the present study was hepatitis E virus (HEV) and followed by hepatitis A virus (HAV). Of total viral hepatitis cases, 31.54% were due to HAV, 6.35% hepatitis B virus, 0.85% hepatitis C virus and 61.24% were due to HEV respectively. In the present study, there was no case of hepatitis D virus has reported. The case fatality rate of viral hepatitis in the present study was minor than 1% (0.98%); whereas males were 0.96%; females of 1.02%. Conclusion: Taking the safety measures including vaccination and proper management of waste materials are the only solution to control or eradicate this infection. PMID:25191049

    The entire staff of the hospital-based home care (HBHC) at Motala (n = 35) participated in a study concerning work stress and job satisfaction. A significant number of the patients in the HBHC have advanced malignancies and most of them are terminally ill. A total of 219 questions about stress and job satisfaction were asked in a self-administered questionnaire. Only 3%-17% of the staff often or very often experienced stress factors such as high expectations, confusing orders, or lack of information. Instead, a majority stated that they often/very often experienced different aspects of job satisfaction, such as meaningfulness, security, and stimulation. Staff members stating that they often were proud/very proud of their jobs, members feeling that their skill and experience were needed, as well as staff members who often received praise from their superiors, were less prone to look for other jobs (p less than 0.01, p less than 0.05, and p less than 0.05, respectively). Those who often/very often were allowed to take initiatives of their own more often regarded their jobs as non-monotonous (p less than 0.05) and stimulating to their personal development (p less than 0.001). Despite demanding jobs with severely ill patients, most of the staff gave high ratings for different aspects of job satisfaction. This positive spirit was also reflected in the exceptionally low job turnover among them. Possible explanations may be a careful selection of personnel and an organization which both stimulates the staff's own initiatives and provides support when necessary. PMID:1941357

    Objective To evaluate a hospital-based educational program to increase child safety restraint knowledge and use among birthing mothers. Methods A prospective experimental and control study was performed in the Obstetrics department of hospitals. A total of 216 new birthing mothers from two hospitals (114 from intervention hospital and 102 from comparison hospital) were recruited and enrolled in the study. Intervention mothers received a height chart, an 8-minute video and a folded pamphlet regarding child safety restraint use during their hospital stay after giving birth. Evaluation data on the child safety seat (CSS) awareness, attitudes, and use were collected among both groups before and after the intervention. An additional phone interview was conducted among the intervention mothers two months after discharge. Results No significant differences existed between groups when comparing demographics. Over 90% of the intervention mothers found the educational intervention to be helpful to some extent. A significantly higher percentage of mothers in the intervention than the comparison group reported that CSS are necessary and are the safest seating practice. Nearly 20% of the intervention mothers actually purchased CSS for their babies after the intervention. While in both the intervention and comparison group, over 80% of mothers identified the ages of two through five as needing CSS, fewer than 50% of both groups identified infants as needing CSS, even after the intervention. Conclusion The results indicated that child safety restraint education implemented in hospitals helps increase birthing mothers' overall knowledge and use of CSS. Further efforts are needed to address specific age-related needs to promote car seats use among infants. PMID:25133502

Methods A cross-sectional survey was distributed to children's hospital-based SRC directors. Survey categories included: funding sources, customer base, items sold, items given free of charge, education provided and directors’ needs. Results 32/38 (84.2%) SRC sites (affiliated with 30 hospitals) completed the survey. SRCs were in many hospital locations including lobby (28.1%), family resource centres (12.5%), gift shop/retail space (18.8%), mobile units (18.8%) and patient clinics (12.5%). 19% of respondents reported that their SRC was financially self-sustainable. Sales to patients predominated (mean of 44%); however, hospital employees made up a mean of 20% (range 0–60%) of sales. 78.1% of SRCs had products for children with special healthcare needs. Documentation kept at SRC sites included items purchased (96.9%), items given free of charge (65.6%) and customer demographics (50%). 56.3% of SRCs provided formal injury prevention education classes. The SRCs’ directors’ most important needs were finances (46.9%), staffing (50%) and space (46.9%). All of the directors were ‘somewhat interested’ or ‘very interested’ in each of the following: creation of a common SRC listserv, national SRC data bank and multisite SRC research platform. Conclusions SRCs are located in many US children's hospitals, and can be characterised as heterogeneous in location, products sold, data kept and ability to be financially sustained. Further research is needed to determine best practices for SRCs to maximise their impact on injury prevention. PMID:24667383

    Background and Objectives: Urinary incontinence is a problem that creates both physical and psychological nuisance to a woman. This problem needs to be studied in detail in Indian population because of lack of precise data. The objectives of this study were to study the prevalence and risk factors of urinary incontinence in Indian women. Materials and Methods: This hospital-based cross-sectional study conducted from August 2005 to June 2007 included women attending gynecology OPD (consulters) and hospital employees (nonconsulters). Subjects who were incontinent were asked a standard set of questions. Incontinence was classified as urge, stress, or mixed based on symptoms. A univariate followed by multivariate analysis was done to look for risk factors. Results: Of 3000 women enrolled, 21.8% (656/3000) women were incontinent. There was no significant difference in incontinence rate between consulters and nonconsulters [618/2804 (22.1%) vs. 38/196 (19.4%); P value = 0.6). Of the total women having incontinence, highest numbers were found to have stress incontinence [73.8% (484/656)] followed by mixed [16.8% (110/656)] and urge incontinence [9.5% (62/656)]. Age more than 40 years; multiparity; postmenopausal status; body mass index more than 25; history of diabetes and asthma; and habit of taking tea, tobacco, pan, and betel are risk factors found to be associated with increased prevalence of urinary incontinence in univariate analysis. On multivariate analysis, age more than 40 years, multiparity, vaginal delivery, hysterectomy, menopause, tea and tobacco intake, and asthma were found to be significantly associated with overall incontinence. Stress incontinence was separately not associated with menopause. Urge incontinence was not associated with vaginal delivery. Conclusion: Urinary incontinence is a bothersome problem for women. Simple questionnaire can help to detect this problem and diagnose associated risk factors, so that necessary steps can be taken in its

    OBJECTIVE: To assess decleration and acceleration in the disease process in the initial phase of epilepsy in children with new onset tonic-clonic seizures. STUDY DESIGN: Hospital based follow up study. SETTING: Two university hospitals, a general hospital, and a children's hospital in the Netherlands. PATIENTS: 204 children aged 1 month to 16 years with idiopathic or remote symptomatic, newly diagnosed, tonic-clonic seizures, of whom 123 were enrolled at time of their first ever seizure; all children were followed until the start of drug treatment (78 children), the occurrence of the fourth untreated seizure (41 children), or the end of the follow up period of two years (85 untreated children). MAIN OUTCOME MEASURES: Analysis of disease pattern from first ever seizure. The pattern was categorised as decelerating if the child became free of seizures despite treatment being withheld. In cases with four seizures, the pattern was categorised as decelerating if successive intervals increased or as accelerating if intervals decreased. Patterns in the remaining children were classified as uncertain. RESULTS: A decelerating pattern was found in 83 of 85 children who became free of seizures without treatment. Three of the 41 children with four or more untreated seizures showed a decelerating pattern and eight an accelerating pattern. In 110 children the disease process could not be classified, mostly because drug treatment was started after the first, second, or third seizure. The proportion of children with a decelerating pattern (42%, 95% confidence interval 35% to 49%) may be a minimum estimate because of the large number of patients with an uncertain disease pattern. CONCLUSIONS: Though untreated epilepsy is commonly considered to be a progressive disorder with decreasing intervals between seizures, a large proportion of children with newly diagnosed, unprovoked tonic-clonic seizures have a decelerating disease process. The fear that tonic-clonic seizures commonly

    Background Japanese encephalitis (JE) is presumed to be endemic throughout Asia, yet only a few cases have been reported in tropical Asian countries such as Indonesia, Malaysia and the Philippines. To estimate the true disease burden due to JE in this region, we conducted a prospective, hospital-based surveillance with a catchment population of 599,120 children less than 12 years of age in Bali, Indonesia, from July 2001 through December 2003. Methods Balinese children presenting to any health care facility with acute viral encephalitis or aseptic meningitis were enrolled. A "confirmed" diagnosis of JE required the detection of JE virus (JEV)-specific IgM in cerebrospinal fluid, whereas a diagnosis of "probable JE" was assigned to those cases in which JEV-specific IgM was detected only in serum. Results In all, 86 confirmed and 4 probable JE cases were identified. The annualized JE incidence rate was 7.1 and adjusted to 8.2 per 100,000 for children less than 10 years of age over the 2.5 consecutive years of study. Only one JE case was found among 96,920 children 10–11 years old (0.4 per 100,000). Nine children (10%) died and 33 (37%) of the survivors had neurological sequelae at discharge. JEV was transmitted in Bali year-round with 70% of cases in the rainy season. Conclusion JE incidence and case-fatality rates in Bali were comparable to those of other JE-endemic countries of Asia. Our findings contradict the common wisdom that JE is rare in tropical Asia. Hence, the geographical range of endemic JE is broader than previously described. The results of the study support the need to introduce JE vaccination into Bali. PMID:16603053

    Pyodermas are a common group of infectious dermatological conditions on which few studies have been conducted. This study aimed to characterise the clinical and bacteriological profile of pyodermas, and to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) infection in primary pyodermas in a dermatology outpatient department in Kashmir. Methods We conducted a hospital based cross-sectional study in the outpatient Department of Dermatology, Sexually Transmitted Diseases and Leprosy of Shri Maharaja Hari Singh Hospital, Srinagar, Jammu and Kashmir, India. Patients presenting with primary pyodermas were included in the study. A detailed history and complete physical and cutaneous examination was carried out along with microbiological testing to find aetiological microorganisms and their respectiveantimicrobial susceptibility patterns. Antimicrobial susceptibility testing, including that for methicillin resistance, was carried out by standard methods as outlined in the current Clinical and Laboratory Standards Institute guidelines. Results In total, 110 patients were included; the age of the study population ranged from 3 to 65 years (mean age 28 years); 62% were male. Poor personal hygiene was noted in 76 (69%). Furunculosis (56; 51%) was the most common clinical presentation. Staphylococcus aureus was isolated in 89 (81%) of cases, and MRSA formed 54/89 (61%) of Staphylococcus aureus isolates. All MRSA strains were sensitive to vancomycin. Conclusion The prevalence of MRSA was high in this sample of communityacquired primary pyodermas. It is therefore important to monitor the changing trends in bacterial infection and their antimicrobial susceptibility patterns and to formulate a definite antibiotic policy which may be helpful in decreasing the incidence of MRSA infection.

    Abstract Background The goal of this study was to describe the hospital-based incidence of traumatic spinal cord injury in Tehran, Iran. Methods We retrospectively reviewed the hospital records of traumatic spinal cord injury patients, admitted between March 2010 and July 2011 in 61/68 hospitals of Tehran. Results Overall, 138 cases of traumatic spinal cord injury were identified. The majority of patients were male (84.8%). The mean age was 33.2 ± 14.3 years. 54.3% patients were residing in Tehran and the others were referred from other cities. The mean annual incidence of hospitalized traumatic spinal cord injury patients of Tehran was 10.5/1,000,000/year (95% confidence interval: 9-12). Fall was the leading cause of injury (45.7%), followed by road traffic crash (40.6%). The most common cause of tetraplegia (cervical traumatic spinal cord injury) was road traffic crash. The duration of hospital stay for tetraplegia and paraplegia (thoracic and lumbar traumatic spinal cord injury) was 22.7±23.7 and 12.5±7.5, respectively (P<0.001). Early surgery (surgical decompression within 24 h) was done for 19% of the patients. The median day of hospitalization for early and late surgery was 7.5 and 12, respectively (P=0.044). Conclusion Preventing traumatic spinal cord injury should focus on males, age group of 21-30 years, falls and road traffic crash. More studies are suggested to evaluate the incidence of non-hospitalized traumatic spinal cord injury patients. PMID:25988093

    In clinical trials, methadone, but not morphine, appeared to prevent beneficial effects of lubiprostone, a ClC-2 Cl(-) channel activator, on opioid-induced constipation. Effects of methadone and morphine on lubiprostone-stimulated Cl(-) currents were measured by short circuit current (Isc) across T84 cells. Whole cell patch clamp of human ClC-2 (hClC-2) stably expressed in HEK293 cells and in a high expression cell line (HEK293EBNA) as well as human CFTR (hCFTR) stably expressed in HEK293 cells was used to study methadone and morphine effects on recombinant hClC-2 and hCFTR Cl(-) currents. Methadone but not morphine inhibited lubiprostone-stimulated Isc in T84 cells with half-maximal inhibition at 100 nM. Naloxone did not affect lubiprostone stimulation or methadone inhibition of Isc. Lubiprostone-stimulated Cl(-) currents in hClC-2/HEK293 cells, but not forskolin/IBMX-stimulated Cl(-) currents in hCFTR/HEK293 cells, were inhibited by methadone, but not morphine. HEK293EBNA cells expressing hClC-2 showed time-dependent, voltage-activated, CdCl2-inhibited Cl(-) currents in the absence (control) and the presence of lubiprostone. Methadone, but not morphine, inhibited control and lubiprostone-stimulated hClC-2 Cl(-) currents with half-maximal inhibition at 100 and 200-230 nM, respectively. Forskolin/IBMX-stimulated hClC-2 Cl(-) currents were also inhibited by methadone. Myristoylated protein kinase inhibitor (a specific PKA inhibitor) inhibited forskolin/IBMX- but not lubiprostone-stimulated hClC-2 Cl(-) currents. Methadone caused greater inhibition of lubiprostone-stimulated currents added before patching (66.1 %) compared with after patching (28.7 %). Methadone caused inhibition of lubiprostone-stimulated Cl(-) currents in T84 cells and control; lubiprostone- and forskolin/IBMX-stimulated recombinant hClC-2 Cl(-) currents may be the basis for reduced efficacy of lubiprostone in methadone-treated patients.

    Industrial plants have become more complex due to technological advancement. This has made the task of maintenance more difficult. The maintenance costs in terms of resources and downtime loss are so high that maintenance function has become a critical factor in a plant's profitability. Industry should devote as much forethought to the management of maintenance function as to production. Maintenance has grown from an art to a precise, technical engineering science. Planning, organizing scheduling and control of maintenance using modern techniques pays dividends in the form of reduced costs and increased reliability. The magnitude and the dimension of maintenance have multiplied due to development in the engineering technologies. Production cost and capacities are directly affected by the breakdown time. Total operating cost including the maintenance cost plays an important role in replacement dimension. The integrated system approach would bring forth the desired results of high maintenance standards. The standards once achieved and sustained, would add to the reliability of the plan and relieve heavy stresses and strains on the engineering logistic support. (author)

    Background Decision analysis in hospital-based settings is becoming more common place. The application of modeling and simulation approaches has likewise become more prevalent in order to support decision analytics. With respect to clinical decision making at the level of the patient, modeling and simulation approaches have been used to study and forecast treatment options, examine and rate caregiver performance and assign resources (staffing, beds, patient throughput). There us a great need to facilitate pharmacotherapeutic decision making in pediatrics given the often limited data available to guide dosing and manage patient response. We have employed nonlinear mixed effect models and Bayesian forecasting algorithms coupled with data summary and visualization tools to create drug-specific decision support systems that utilize individualized patient data from our electronic medical records systems. Methods Pharmacokinetic and pharmacodynamic nonlinear mixed-effect models of specific drugs are generated based on historical data in relevant pediatric populations or from adults when no pediatric data is available. These models are re-executed with individual patient data allowing for patient-specific guidance via a Bayesian forecasting approach. The models are called and executed in an interactive manner through our web-based dashboard environment which interfaces to the hospital's electronic medical records system. Results The methotrexate dashboard utilizes a two-compartment, population-based, PK mixed-effect model to project patient response to specific dosing events. Projected plasma concentrations are viewable against protocol-specific nomograms to provide dosing guidance for potential rescue therapy with leucovorin. These data are also viewable against common biomarkers used to assess patient safety (e.g., vital signs and plasma creatinine levels). As additional data become available via therapeutic drug monitoring, the model is re-executed and projections are

    Background Plasmodium malariae is a slow-growing parasite with a wide geographic distribution. Although generally regarded as a benign cause of malaria, it has been associated with nephrotic syndrome, particularly in young children, and can persist in the host for years. Morbidity associated with P. malariae infection has received relatively little attention, and the risk of P. malariae-associated nephrotic syndrome is unknown. Methodology/Principal Findings We used data from a very large hospital-based surveillance system incorporating information on clinical diagnoses, blood cell parameters and treatment to describe the demographic distribution, morbidity and mortality associated with P. malariae infection in southern Papua, Indonesia. Between April 2004 and December 2013 there were 1,054,674 patient presentations to Mitra Masyarakat Hospital of which 196,380 (18.6%) were associated with malaria and 5,097 were with P. malariae infection (constituting 2.6% of all malaria cases). The proportion of malaria cases attributable to P. malariae increased with age from 0.9% for patients under one year old to 3.1% for patients older than 15 years. Overall, 8.5% of patients with P. malariae infection required admission to hospital and the median length of stay for these patients was 2.5 days (Interquartile Range: 2.0–4.0 days). Patients with P. malariae infection had a lower mean hemoglobin concentration (9.0g/dL) than patients with P. falciparum (9.5g/dL), P. vivax (9.6g/dL) and mixed species infections (9.3g/dL). There were four cases of nephrotic syndrome recorded in patients with P. malariae infection, three of which were in children younger than 5 years old, giving a risk in this age group of 0.47% (95% Confidence Interval; 0.10% to 1.4%). Overall, 2.4% (n = 16) of patients hospitalized with P. malariae infection subsequently died in hospital, similar to the proportions for the other endemic Plasmodium species (range: 0% for P. ovale to 1.6% for P. falciparum

    Background Recent experience with pandemic influenza A(H1N1)pdm09 highlighted the importance of global surveillance for severe respiratory disease to support pandemic preparedness and seasonal influenza control. Improved surveillance in the southern hemisphere is needed to provide critical data on influenza epidemiology, disease burden, circulating strains and effectiveness of influenza prevention and control measures. Hospital-based surveillance for severe acute respiratory infection (SARI) cases was established in New Zealand on 30 April 2012. The aims were to measure incidence, prevalence, risk factors, clinical spectrum and outcomes for SARI and associated influenza and other respiratory pathogen cases as well as to understand influenza contribution to patients not meeting SARI case definition. Methods/Design All inpatients with suspected respiratory infections who were admitted overnight to the study hospitals were screened daily. If a patient met the World Health Organization’s SARI case definition, a respiratory specimen was tested for influenza and other respiratory pathogens. A case report form captured demographics, history of presenting illness, co-morbidities, disease course and outcome and risk factors. These data were supplemented from electronic clinical records and other linked data sources. Discussion Hospital-based SARI surveillance has been implemented and is fully functioning in New Zealand. Active, prospective, continuous, hospital-based SARI surveillance is useful in supporting pandemic preparedness for emerging influenza A(H7N9) virus infections and seasonal influenza prevention and control.

    The role of the leader of a medical unit has evolved over time to expand from simply a medical role to a more managerial one. This study aimed to explore how the behavior of a hospital-based emergency department's (ED's) leader might be related to ED unit performance and ED employees' work satisfaction. One hundred and twelve hospital-based EDs in Taiwan were studied: 10 in medical centers, 32 in regional hospitals, and 70 in district hospitals. Three instruments were designed to assess leader behaviors, unit performance and employee satisfaction in these hospital-based EDs. A mail survey revealed that task-oriented leader behavior was positively related to ED unit performance. Both task- and employee-oriented leader behaviors were found to be positively related to ED nurses' work satisfaction. However, leader behaviors were not shown to be related to ED physicians' work satisfaction at a statistically significant level. Some ED organizational characteristics, however, namely departmentalization and hospital accreditation level, were found to be related to ED physicians' work satisfaction. PMID:21159414
