    The institution of methadone maintenance as a treatment modality for heroin addiction in the mid-1960s was part of the growing medicalization of social problems in the United States. The definition of deviance as "sickness" rather than "badness" set the stage for America's first harm-reduction strategy. By the 1970s methadone maintenance was seen as a way to reduce drug-related crime, and federally funded programs proliferated. Accompanying methadone's phenomenal expansion was increased regulation, bureaucratization, and criticism. The early 1980s brought the Reagan era, fiscal austerity, the new "just say no" abstinence morality, and demedicalization of methadone maintenance. By the time needle-sharing was recognized as a major contributing factor in the spread of HIV, methadone had been transformed into a largely fee-for-service, short-term, begrudgingly tolerated treatment modality. Ironically, while other countries were able to use methadone to curb the spread of AIDS, the United States refused to facilitate its expansion, and in fact impeded it. To the frustration of proponents and consumers, this original harm-reduction tool, with the potential to impact the epidemic, was demedicalized and remains marginalized. PMID:7562261

    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

    Using data from an evaluation of methadone maintenance treatment, this study investigated factors associated with continued involvement in crime during treatment, and in particular whether there appeared to be differences in effectiveness of treatment between different methadone clinics. The methodology was an observational study, in which 304 patients attending three low-intervention, private methadone clinics in Sydney were interviewed on three occasions over a twelve month period. Outcome measures were self-reported criminal activity and police department records of convictions. By self-report, crime dropped promptly and substantially on entry to treatment, to a level of acquisitive crime about one-eighth that reported during the last addiction period. Analysis of official records indicated that rates of acquisitive convictions were significantly lower in the in-treatment period compared to prior to entry to treatment, corroborating the changes suggested by self-report. Persisting involvement in crime in treatment was predicted by two factors: the cost of persisting use of illicit drugs, particularly cannabis, and ASPD symptom count. Treatment factors also were independently predictive of continued involvement in crime. By both self-report and official records, and adjusting for subject factors, treatment at one clinic was associated with greater involvement in crime. This clinic operated in a chaotic and poorly organized way. It is concluded that crime during methadone treatment is substantially lower than during street addiction, although the extent of reduction depends on the quality of treatment being delivered.

  6. Pharmacogenomics of methadone maintenance treatment.

    Methadone is the major opioid substitution therapy for opioid dependence. Dosage is highly variable and is often controlled by the patient and prescriber according to local and national policy and guidelines. Nevertheless many genetic factors have been investigated including those affecting its metabolism (CYP2B6-consistent results), efflux transport (P-gp-inconsistent results), target μ-opioid receptor (μ-opioid receptor-inconsistent results) and a host of other receptors (DRD2) and signaling elements (GIRK2 and ARRB2; not replicated). None by themselves have been able to substantially explain dosage variation (the major but not sole end point). When multiple genes have been combined such as ABCB1, CYP2B6, OPRM1 and DRD2 a greater contribution to dosage variation was found but not as yet replicated. As stabilization of dosage needs to be made rapidly, it is imperative that larger internationally based studies be instigated so that genetic contribution to dosage can be properly assessed, which may or may not tailor to different ethnic groups and each country's policy towards an outcome that benefits all.

    Few well-controlled studies have examined psychomotor and cognitive performance in methadone maintenance patients (MMP). In the present study, performance of 18 opioid-dependent MMP was evaluated relative to that of 21 control participants without substance abuse histories. The MMP and control groups were balanced with respect to gender, race, age, years of education, current employment status, current reading level, and estimated IQ score. Recent drug abstinence was verified by urine testing. Participants with a urine screen positive for benzodiazepines or a breathalyzer test positive for alcohol prior to performance testing were excluded. To avoid testing under conditions of acute heroin or cocaine intoxication, but without testing under conditions of acute withdrawal, participants with current use of heroin or cocaine were only required to abstain for 24 h prior to performance testing. MMP exhibited impairment relative to controls in psychomotor speed (digit symbol substitution and trail-making tests), working memory (two-back task), decision making (gambling task), and metamemory (confidence ratings on a recognition memory test); results also suggested possible impairment in inhibitory mechanisms (Stroop color-word paradigm). MMP did not exhibit impairment in time estimation, conceptual flexibility or long-term memory. The wide range of impaired functions is striking, and may have important implications for daily functioning in MMP. Further research is necessary to determine the clinical significance of the impairments in laboratory-based tests for daily performance in the natural environment, as well as to differentiate impairments due to acute methadone dosing, chronic methadone maintenance, chronic poly-drug abuse, and other factors.

    Background Methadone Maintenance Treatment is a useful method for opioid dependents, which results in harm reduction and increased quality of life in opioid dependents. The prevalence of psychiatric disorders in addicts is higher than in the general population which can interfere with the course and treatment of substance dependents and decrease the efficacy of treatment. Methods This descriptive, cross-sectional study was aimed to determine the correlation between psychiatric disorders and methadone dosage. It was performed on 154 patients of Kerman Shahid Beheshti Hospital’s Methadone Clinic during a six month period from Dec 2010 to Jul 2011. The study population was chosen by convenience sampling. The searching tools were Socio-Demographic Questionnaire, psychiatric structured interview based on DSM-IV-TR, Beck Depression Inventory, Young Mania Rating Scales, and Anxiety and Depression Rating Scales. Findings Significant correlations were observed between increased methadone dosage and antisocial personality disorder. In addition, significant positive correlations were observed between increased methadone dosage and Hamilton anxiety scores, Hamilton depression scores and Young Mania scores. Conclusion High methadone dosage may be a marker of coexisting psychiatric disorders in patients on methadone maintenance treatment which indicates the necessity of devoting further attention to this group. Psychiatric services should be open and accessible to the patients, especially those who seek treatment voluntarily. Early diagnosis and treatment of patients with coexisting psychiatric disorders may increase the efficacy of methadone maintenance treatment. PMID:24494130

    Gas chromatography-mass spectrometry quantitative method was developed to monitor concentrations of methadone and its metabolite 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) in plasma and urine of patients. The developed method was simple, accurate and reproducible to quantify methadone and EDDP in plasma and urine samples in the concentration range of 15-1,000 and 50-2,000 ng/mL, respectively. The proposed analytical method was applied to plasma and urine samples obtained from 96 patients undergoing methadone maintenance treatment (MMT) with daily methadone doses of 2-120 mg/day. Urinary methadone excretion was observed to be significantly affected by pH, in which the ratio of methadone to EDDP was two times higher in acidic urine (P = 0.029). The findings of this study further enhance the guidelines for monitoring of methadone treatment among outpatients. Methadone-to-EDDP ratio in urine was found to be consistent at 24 and 4 h, hence suggesting the possibility that outpatients may be monitored with single urine sample in order to check for compliance. This study which provides data on peak concentrations of methadone and EDDP as well as the ratio of both compounds has added to the body of knowledge regarding pharmacokinetic properties of methadone among heroin-dependent patients under MMT.

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

    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

    2016-01-01

    Study Objectives: Methadone maintenance treatment (MMT) patients have a high prevalence of central sleep apnea and ataxic breathing related to damage to central respiratory rhythm control. However, the quantification of sleep apnea indices requires laborious manual scoring, and ataxic breathing pattern is subjectively judged by visual pattern recognition. This study proposes a semi-automated technique to characterize respiratory variability in MMT patients. Methods: Polysomnography, blood, and functional outcomes of sleep questionnaire (FOSQ) from 50 MMT patients and 20 healthy subjects with matched age, sex, and body mass index, were analyzed. Inter-breath intervals (IBI) were extracted from the nasal cannula pressure signal. Variability of IBI over 100 breaths was quantified by standard deviation (SD), coefficient of variation (CV), and scaling exponent (α) from detrended fluctuation analysis. The relationships between these variability measures and blood methadone concentration, central sleep apnea index (CAI), apnea-hypopnea index (AHI), and clinical outcome (FOSQ), were then examined. Results: MMT patients had significantly higher SD and CV during all sleep stages. During NREM sleep, SD and CV were correlated with blood methadone concentration (Spearman R = 0.52 and 0.56, respectively; p < 0.01). SD and CV were also correlated with CAI (R = 0.63 and 0.71, p < 0.001, respectively), and AHI (R = 0.45 and 0.58, p < 0.01, respectively). Only α showed significant correlation with FOSQ (R = −0.33, p < 0.05). Conclusions: MMT patients have a higher respiratory variability during sleep than healthy controls. Semi-automated variability measures are related to apnea indices obtained by manual scoring and may provide a new approach to quantify opioid-related sleep-disordered breathing.

    Background Intimate partner violence (IPV) is a highly prevalent and concerning problem among methadone maintenance populations, and previous studies have shown a relationship between a history of IPV and increased substance use and affective disturbances. Methods The current study examined 1) the association between recent IPV victimization and alcohol and cocaine use and 2) the relationship between recent IPV victimization and depression in a sample of smokers (n=203) in methadone maintenance treatment (MMT). Participants in this study completed a battery of assessments that included standard questionnaires of trauma, alcohol and substance use, and depression. Parallel logistic and linear regression models were used to estimate the adjusted association of IPV victimization and depressive symptoms and evaluate the adjusted association of victimization with recent substance use. Results Participants recently victimized by partners were shown to have significantly higher mean CES-D scores (b = 0.54, 95%CI 0.07; 1.02, p < .05) and were found to have a 6 times greater likelihood of cocaine use (OR = 6.65, 95%CI 1.61; 27.46, p < .01) after controlling for age, gender, education, opiate use and ethnicity. Conclusions These findings support the notion that IPV victimization can potentially increase depression and other substance use among MMT patients, which can have a deleterious impact on treatment.

    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

    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.

    We describe the historical underpinnings of negative attitudes towards methadone and how these affect medical decisions. Current developments have increased the understanding of the origins of opioid addiction, such as how receptor system dysfunction may affect the ability to remain abstinent once out of treatment. Specialized topics include the pregnant addict, the role of methadone maintenance in limiting the spread of the acquired immunodeficiency syndrome, and patients with a dual diagnosis. We also describe issues that arise when methadone is used in conjunction with prescribed or abused drugs, noting pharmacologic alternatives and adjuncts to methadone treatment. Finally, we comment on treatment issues such as methadone patients in 12-step programs and the growing legitimacy of this treatment method.

    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

    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

    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.

    Pregnant women in methadone maintenance therapy may have poor nutrition during pregnancy. In 2006–2008, methadone treated pregnant women (n = 22) were recruited at an urban academic medical center and compared with non-drug using pregnant women (n = 119) at 20–35 weeks gestation. We measured adiposity using pre-pregnancy body mass index (BMI), dietary intake using a food frequency questionnaire, and micronutrient and essential fatty acid status using biomarkers. Methadone treated women had lower BMI, consumed more calories, had lower serum carotenoid concentrations and higher plasma homocysteine concentrations than controls. The study’s limitations and implications for future research are discussed. PMID:22217127

    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

    To characterize sleep disorders in methadone maintenance treatment (MMT) patients, we evaluated sleep quality of 101 non-selective patients from our MMT clinic in Israel between July, 2003 and July, 2004 by using the self-report questionnaire Pittsburgh Sleep Quality Index (PSQI). Patients' urine tests were analyzed for methadone metabolite, opiates, benzodiazepine, cocaine, cannabis and amphetamines. Their urine results for drug abuse throughout the months prior to filling in the questionnaire and their maintenance methadone doses were recorded. Drug abuse was defined by at least one positive urine test. Methadone serum levels were available in 55 patients, assessed by Gas Chromatography Mass Spectroscopy. The patients' self-reported chronic pain questionnaires and their diagnosed psychiatric disorders were analyzed. Out of the 101 study patients, 78.2% were male, 52.5% had psychiatric disorders, 46.5% reported having chronic pain and 46.5% had positive urine for benzodiazepine. The mean daily methadone dose was 157+/-52.9 mg. The mean PSQI score was 9+/-4.8 (75.2% had scores >5 indicating "poor sleepers"). PSQI scores were higher in patients with positive urine for benzodiazepine, chronic pain and psychiatric disorders and they correlated with years of opiate abuse before admission to MMT, and with the methadone dose (r=0.48, p<0.0005). The latter two also correlated with each other. The PSQI was not correlated with duration in MMT, gender, age, abuse of opiates, cannabis or cocaine. We concluded that sleep disorders should be evaluated and treated among MMT patients, particularly in those with psychiatric disorders, benzodiazepine abuse, chronic pain and high methadone dose.

    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: Methadone maintenance treatment programs implemented in Aboriginal communities have proven to be beneficial for the control of opioid addiction and its associated consequences, but the perceptions and opinions of different community members about these programs remain elusive. The goal of this study was to determine the perceptions of members of a First Nation community in New Brunswick, Canada, on the implementation of a methadone maintenance treatment program and its effects on the community. Methods: We conducted a qualitative study using semistructured focus group discussions with 3 distinct groups composed of health care professionals and influential community members, patients in the methadone maintenance treatment program and community members at large. Thematic analysis of discussion transcripts was performed. Results: A total of 22 partipants were included in the 3 focus groups. All groups of participants expressed that patients in the program are stigmatized and marginalized. Discussions also revealed widespread misconceptions about the program. Participants associated the program with improvements in community-level outcomes and in parenting abilities of patients, but also with difficulties preserving family unity. Interpretation: Despite being culturally adapted to the community, elements surrounding the methadone maintenance treatment program in this First Nation community appear to be misunderstood and stigmatized. It may be beneficial to provide community education on these programs to assure community buy-in for the successful implementation of harm reduction programs in Aboriginal communities. PMID:27730106

    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

    The study examined whether closing of a methadone maintenance clinic in Israel on the Sabbath was associated with adverse patient outcomes. One take-home dose of methadone was given to all patients for that day regardless of whether they had earned take-home privileges. No difference was found in dropout rates for the six-month periods before and after Saturday closure was initiated. Results of random, twice-weekly urinalyses for all patients did not indicate increased use of heroin. The findings suggest that closure of a methadone clinic at least one day a week does not jeopardize patient outcome. Cutting hours of operation would reduce workload and enable clinics to function more economically.

    After changing the weekend closure of our methadone maintenance clinic from 1 to 2 days, we compared patients' retention in treatment, discount payment privileges, take-home doses, and rate of drugs in urine tests during the 6 months before and after the change. No differences were found in the 6-month retention rate (94.6% and 95.4%, respectively), take-home dose privileges (60.9% and 58%, respectively), or the rate of urines positive to all substance abuse. Expanding closure of the clinic for a 2-day weekend had no adverse effect on treatment parameters, suggesting that a methadone maintenance clinic may keep the same hours as other hospital's outpatient clinics.

    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

    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.

    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

    Injection drug users constitute 60% of the more than 4 million people in the United States with hepatitis C virus (HCV), including many methadone maintenance patients. Few data exist describing clinical outcomes for patients receiving HCV treatment on-site in a methadone maintenance settings. In this retrospective study, we describe clinical outcomes for 73 patients receiving HCV treatment on-site in a methadone maintenance treatment program. Fifty-five percent of patients achieved end-of-treatment response, and 45% achieved sustained viral response. These treatment response rates are nearly equivalent to previously published HCV treatment response rates, despite high prevalences of ongoing drug use (49%), psychiatric comorbidity (67%), and HIV coinfection (32%). These data show that on-site HCV treatment with pegylated interferon and ribavirin is effective in methadone-maintained patients, many of whom are active drug users, psychiatrically ill, or HIV coinfected, and that methadone maintenance treatment programs represent an opportunity to safely treat chronic hepatitis C.

    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.

    Background The aim of this study was to estimate the cost-effectiveness of injectable extended release naltrexone (XR-NTX) compared to methadone maintenance and buprenorphine maintenance treatment (MMT and BMT respectively) for adult males enrolled in treatment for opioid dependence in the United States from the perspective of state-level addiction treatment payers. Methods We used a Markov model with daily time cycles to estimate the incremental cost per opioid-free day in a simulated cohort of adult males ages 18–65 over a six-month period from the state health program perspective. Results XR-NTX is predicted to be more effective and more costly than methadone or buprenorphine in our target population, with an incremental cost per opioid-free day gained relative to the next-most effective treatment (MMT) of $72. The cost-effectiveness of XR-NTX relative to MMT was driven by its effectiveness in deterring opioid use while receiving treatment. Conclusions XR-NTX is a cost-effective medication for treating opioid dependence if state addiction treatment payers are willing to pay at least $72 per opioid-free day. PMID:25775099

    The aim of the study was to evaluate the nutritional status of opiate dependent patients before and after 4 years of participation in the methadone maintenance treatment. The examinations were performed in 30 opiates addicted persons (7 women and 23 men). The initial examination (exam 1) was done during the patients qualification for the methadone program, preceding methadone administration and final examination (exam 2) after 4 years of the treatment. In order to estimate the nutritional status body mass, the height, the arm circumference and the thickness of the triceps and subscapular fat-skin folds were measured. On the basis of them the BMI and mid arm muscle circumference (MAMC) were counted. The measurements of the body composition (using the bioimpedance method) were performed. The changes between the results of subsequent examination were tested using the t-Student test. In the examination that took place after 4 years of follow-up, body weight loss in the group of women was observed (mean--1.7 kg). It was followed by the decrease of BMI value (from 20.3 to 19.8 kg/m2). In both examinations the percentage of fatty tissue in general body mass was significantly below recommended values (10.7% in both examinations--the recommended values are 20%-22%). In the group of men an increase in body weight (mean--8.8 kg) and BMI value (from 23.3 to 25.9 kg/m2) was noticed. Arm circumference, muscle arm circumference and fat-skin folds values were increased. The analysis of particular body components showed increased fatty body mass (11.9% in the first and 18.5% in the second examination--the recommended values 16-19%) together with the decrease of lean body mass and body water.

    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

    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

    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.

    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

    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.

    Aims This study examines the preliminary outcomes of an intervention targeting service providers in methadone maintenance therapy clinics in China. The intervention effects on both service providers and clients are reported. Design The MMT CARE intervention pilot was developed and implemented collaboratively with local health educators. After three group intervention sessions, trained providers in intervention clinics delivered two individual motivational interviewing sessions with their clients. Settings Six clinics in Sichuan, China, were randomized to either the MMT CARE intervention condition or a standard care condition. Participants A total of 41 providers and 179 clients were sampled from the six clinics. Measurements At baseline and 3-, 6-, and 9-month assessments, providers completed self-administrated paper/pencil questionnaires regarding provider-client interaction, methadone maintenance therapy knowledge, perceived job-related stigma, and clinic support. Clients completed a face-to-face survey about their concurrent drug use and drug avoidance self-efficacy. Mixed-effects regression models with clinic-level random effect were used to assess the intervention effects. Findings Significant intervention effects for providers were found in improved methadone maintenance therapy knowledge, provider-client interaction, and perceived clinic support. For clients, better improvements in drug avoidance self-efficacy and reduced concurrent drug use were observed for the intervention compared to the standard care group. Conclusions The methadone maintenance therapy CARE intervention targeting providers in methadone maintenance clinics can improve providers’ treatment knowledge and their interaction with clients. The intervention can also reduce clients’ drug using behavior through motivational interviewing sessions conducted by trained providers. PMID:22788780

    Background Methadone is a synthetic opioid and receptor agonist morphine; thus, its consumption has the effects and side effects of opioid. Methadone maintenance treatment (MMT) is used as an alternative treatment for people who are suffering from substance abuse and do not have the ability to withdraw. Despite its benefits, this drug also has side effects. The purpose of this study was to investigate the effects of methadone treatment on sexual function, sleep, and weight after 6 months. Methods The study subjects consisted of 200 patients who had referred to the Methadone Clinic of Shahid Beheshti Training Hospital, Kerman, Iran, during a 6-month period and were treated using MMT. Data collection tools consisted of the demographic questionnaire, Pittsburgh sleep quality index (PSQI), and Arizona sexual experience scale (ASEX). The questionnaires were completed by the participants before and 6 months after the treatment. Findings The results of this study showed that methadone consumption has significant effects on sexual dysfunction, sleep disorders, and weight gain. Conclusion The consideration of the side effects of MMT can result in consumers’ commitment to the treatment. PMID:26322207

    AIMS To investigate the influence of different cytochrome P450 (CYP) activities and other potential covariates on the disposition of methadone in patients on methadone maintenance therapy (MMT). METHODS Eighty-eight patients (58 male; 21–55 years; 84 White) on MMT were studied. CYP2D6 activity [3 h plasma metabolic ratio of dextromethorphan (DEX) to dextrorphan (DOR)] was determined in 44 patients (29 male; 24–55 years), CYP1A2 activity (salivary caffeine elimination half-life) in 44 patients (21 male; 24–55 years) and CYP3A activity (oral clearance of midazolam) in 49 patients (33 male; 23–55 years). Data on all three CYPs were obtained from 32 subjects. Total plasma concentrations of (RS)-methadone and total and unbound plasma concentrations of both enantiomers were measured by LC/MS. Population pharmacokinetics and subsequent multiple regression analysis were used to calculate methadone oral clearance and to identify its covariates. RESULTS Between 61 and 68% of the overall variation in total plasma trough concentrations of (RS)-, (R)- and (S)-methadone was explained by methadone dose, duration of addiction before starting MMT, CYP3A activity and illicit morphine use. CYP3A activity explained 22, 16, 15 and 23% of the variation in unbound (R)-, unbound (S)-, total (RS)- and total (S)-methadone clearances, respectively. Neither CYP2D6 nor CYP1A2 activity was related to methadone disposition. CONCLUSIONS CYP3A activity has a modest influence on methadone disposition. Inhibitors and inducers of this enzyme should be monitored in patients taking methadone. PMID:19133059

    Background Little is known about attitudes toward and experiences with opioid maintenance therapy (OMT) among people who inject drugs in Malaysia, a country where people who inject drugs comprise 1.3% of the adult population. Methods In 2010, 460 people who inject drugs in Greater Kuala Lumpur, Malaysia were surveyed to evaluate attitudes toward and experience with OMT and treatment readiness. Attitudes towards OMT with both methadone and buprenorphine were assessed using an opinions scale. Multivariable linear regression was used to assess correlates of treatment readiness, measured with the 19-item Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES). Results All 460 participants used opioids and nearly all (99.1%) met criteria for opioid dependence. Few had had previous experience with methadone (9.3%) or buprenorphine (12.6%) maintenance therapy, yet many had used methadone (55.2%) or buprenorphine (51.7%) outside of treatment settings. Fifteen percent had injected buprenorphine in the past month, and of the few that were currently receiving buprenorphine maintenance therapy, almost all were injecting it. The majority of subjects exhibited a moderate level of treatment readiness and a preference for methadone over buprenorphine. Those with low treatment readiness scores were more likely to have previous experience with compulsory drug detention centers (p<0.01), needle/syringe exchange programs (p<0.005), or be of Indian ethnicity (p<0.001). Past use of methadone (p<0.01), older age (p<0.001), stress symptom severity (p<0.001), and sharing of needles or syringes (p<0.05) were associated with higher treatment readiness scores. Conclusion There are suboptimal levels of OMT experience among people who inject drugs that may be improved by addressing factors that influence patient attitudes. Those individuals with moderate treatment readiness may be targeted by brief motivational and cognitive interventions in primary care, prisons or OMT clinics

    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

    Personality disorders and particularly antisocial personality disorders (APD) are quite frequent in opioid-dependent subjects. They show various personality traits: high neuroticism, high impulsivity, higher extraversion than the general population. Previous studies have reported that some but not all personality traits improved with treatment. In a previous study, we found a low rate of APD in a French population of opioid-dependent subjects. For this reason, we evaluated personality traits at intake and during maintenance treatment with methadone. Methods - The form A of the Eysenck Personality Inventory (EPI) was given to opioid addicts at intake and after 6 and 12 months of methadone treatment. Results - 134 subjects (96 males and 38 females) took the test at intake, 60 completed 12 months of treatment. After 12 months, the EPI Neuroticism (N) and the Extraversion-introversion (E) scale scores decreased significantly. The N score improved in the first 6 months, while the E score improved only during the second 6 months of treatment. Compared to a reference group of French normal controls, male and female opioid addicts showed high N and E scores. Demographic data and EPI scores of patients who stayed in treatment for 12 months did not differ significantly from those of dropouts (n=23). Patients with a history of suicide attempts (SA) started to use heroin at an earlier age and they showed a higher E score and a tendency for a higher N score at intake. Discussion - The two personality dimensions of the EPI changed during MMT, and the N score converged towards the score of normal controls. Opioid addicts differ from normal controls mostly in their N score. The EPI did not help to differentiate 12-month completers from dropouts. Higher E scores in patients with an SA history might reflect a higher impulsivity, which has been linked to suicidality in other patient groups.

    Background Retention in treatment is a key factor to the success of methadone maintenance treatment (MMT) and considered an important measure in evaluation of treatment effectiveness. Objectives This study aimed to investigate the retention rate and predictors of retention in MMT in Rafsanjan. Patients and Methods This was a historical cohort study. A total of 1396 patients admitted between March 2011 and March 2012 in 16 MMT clinics (13 private and 3 state clinics) in Rafsanjan, entered the study and their retention rate was examined for one year. The patients’ data abstracted from their medical records using checklists and collected by clinics’ staff. Data analyses were performed using SPSS 15.0 and SAS 9.1. Kaplan-Meier method and Cox proportional hazards model were used to determine the retention rate and identify predictors of retention, respectively. Results The mean age of 1396 patients was 37.65 ± 10.77 years and most patients were men (93.8%). The mean and median of retention duration were 193.22 ± 3.83 and 153 ± 9.54 days, respectively. Three-month and one-year retention rates were 66.0% and 34.4%, respectively. Predictor variables of one-year retention in Cox proportional hazards model were high methadone dosage, polysubstance abuse and treatment under state clinics. Conclusions In this study, retention rate was lower compared to previous studies from other countries. The results suggested that program related factors are better predictors of retention than individual related ones. PMID:27803890

    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

    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.

    The utility of traits associated with Antisocial Personality Disorder in making risk assessments of violent and nonviolent crimes was examined in 254 subjects sampled from a methadone maintenance population. A factor analysis of a number of baseline measures resulted in five factors measuring hostility, insecure attachment, impaired reality testing, antisocial personality, and empathy. These factors were used in logistic regression analysis to predict charges for violent and nonviolent crimes over a 2-year period. Individuals with high scores on the antisocial personality factor had an increased risk of both violent and nonviolent criminal charges. Individuals with low scores on the empathy factor were at high risk for violent crimes. In an analysis using the factor components rather than the factors, the measures of perspective-taking and a socialization were associated with violent criminal charges, and the measure of psychopathy, but not antisocial behavior, was associated with nonviolent criminal charges. The results support the use of measures of personality traits in addition to measures of a history of antisocial behavior in making violence risk assessments in substance-dependent patients. The DSM construct and diagnosis of Antisocial Personality Disorder may be enhanced by greater emphasis on personality traits associated with antisocial behavior.

    Five cigarette smoking methadone maintenance patients (MMP) participated in a within-subjects (A-B-A-B) study involving repeated application of carbon monoxide (CO)-contingent payments for reductions in smoke intake. To replicate and extend findings from an earlier study in non-drug-abusing smokers (Stitzer & Bigelow, 1982), we used the same contingent reinforcement procedure that involved the delivery of a monetary payment ($5) for CO readings which were 50% or less than the average value of readings obtained during the prior noncontingency period. Although four of the five subjects earned the contingent payment on at least three of the eight occasions, the overall effect of the intervention on CO level was nonsignificant. Daily smoking records revealed significantly lower rates during the first contingency intervention for the group as a whole. Significant correlations between CO and the time interval since smoking prior to CO measurement were found. The rather modest intervention effects suggest that important parameters be considered when designing contingency management procedures to reduce cigarette smoking in this difficult population of drug abusers.

    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

    Objectives Opioid-dependent patients treated with methadone have subjective sleep complaints and disrupted sleep on polysomnography (PSG). Previous studies of sleep-disordered breathing (SDB) in this population have focused on central sleep apnea (CSA). Our objectives were to: (1) characterize obstructive sleep apnea (OSA) and CSA in patients in methadone maintenance treatment (MMT) for opioid dependence; (2) examine factors associated with SDB in this population; and (3) investigate whether SDB was related to severity of subjective sleep complaints in MMT patients with subjective sleep disturbances. Methods We analyzed OSA and CSA from one night of home PSG in 71 patients who were in MMT for at least 3 months and had a Pittsburgh Sleep Quality Inventory (PSQI) score > 5. Results OSA (defined as obstructive apnea-hypoponea index (OAHI) ≥ 5) was observed in 35.2% of our sample. OSA was associated with higher body mass index, longer duration in MMT, and non-Caucasian race. CSA (defined as central apnea index (CAI) ≥ 5) was observed in 14.1% of the sample. CSA was not associated with methadone dose or concomitant drug use. Subjective sleep disturbance measured with the PSQI was not related to OSA or CSA. Conclusions SDB was common in this sample of MMT patients and OSA was more common than CSA. Given the lack of association between presence of SDB and severity of subjective sleep difficulties, factors other than sleep apnea must account for complaints of disturbed sleep in this population.

    Background Little is known about the experience of chronic pain and the occurrence of illicit drug use behaviors in the population enrolled in methadone maintenance treatment (MMT) programs. Methods This is a secondary analysis of longitudinal data from two MMT samples enrolled in a randomized controlled trial of hepatitis care coordination. Patients completed pain, illicit drug use, and other questionnaires at baseline and 3, 9, and 12 months later. Associations were sought over time between the presence or absence of clinically significant pain (average daily pain ≥ 4 or mean pain interference ≥ 4 during the past week) and current illicit drug use (i.e., non-therapeutic opioid, cocaine or amphetamine use identified from self-report or urine drug screening). Results Of 404 patients providing complete data, within-patient variability in pain and illicit drug use was high across the 4 assessment periods. While 263 denied pain at baseline, 118 (44.9%) later experienced clinically significant pain during ≥ 1 follow-up assessments. Of 180 patients (44.6%) without evidence of illicit drug use at baseline, only 109 (27.0%) had similar negative drug use at all follow-up assessments. Across four assessment periods, there was no significant association between pain group status and current illicit drug use. Conclusions This one-year longitudinal analysis did not identify a significant association between pain and illicit drug use in MMT populations. This finding conflicts with some earlier investigations and underscores the need for additional studies to clarify the complex association between pain and substance use disorders in patients in MMT program settings.

    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

    Objectives Despite high rates of hepatitis C virus (HCV) infection, relatively few current or former injection drug users receive evaluation and treatment for HCV. Here, we demonstrate the feasibility and effectiveness of integrating HCV care and methadone maintenance treatment (MMT). We hypothesized that colocation of these services would result in improved access to and utilization of HCV care. Methods In this retrospective observational study, all patient charts from a single MMT clinic were reviewed 2 years after HCV care and MMT were integrated. Information obtained included screening for and counseling about HCV infection status, on-site HCV treatment and outcomes, and demographic and substance abuse data. Results Two hundred ninety-one patient charts were reviewed. Two hundred eighty-one (99%) patients were screened for HCV antibody (HCV-Ab), and 188 (65%) were positive. Forty-nine (17%) patients were HIV/HCV coinfected. Ninety-eight percent of the HCV-Ab-positive patients received HCV counseling. Hundred fifty-nine (85%) of the HCV-Ab-positive patients were eligible to receive further evaluation and treatment for HCV on site, and 125 (78%) accepted. Hundred eighteen (94%) patients were tested for chronic HCV, and 83 were determined to have chronic HCV. Twenty-five patients received liver biopsy; low-stage disease was found in 7 patients. Twenty-one patients initiated HCV treatment. Sustained viral response was achieved in 8 patients. Seventeen patients had contraindications to HCV treatment. Further workup was prevented or delayed in 45 patients for various reasons, most commonly due to personal choice (29 patients). Conclusions This study demonstrates that current and former injection drug users can be engaged successfully in evaluation and treatment of HCV infection when these services are collocated with MMT.

    Methadone maintenance treatment (MMT) is efficacious in reducing drug use that may improve HIV/AIDS care and treatment outcomes. This study evaluated the incremental cost-effectiveness of MMT for HIV-positive drug users from the perspective of health service providers. A sample of 370 HIV-positive drug users (age: mean ± SD: 29.5 ± 5.9 years; 95.7% male) taking MMT in multi-sites was assessed at baseline, three, six and nine months. Costs of MMT services were analyzed and converted to the year 2009. Quality-adjusted life years (QALYs) were modeled from changes in health-related quality of life of patients using the modified World Health Organization Quality of Life - Brief Version (WHOQOL-BREF). Inverse probability-of-treatment weights, constructed using propensity score of non-responses, were applied to adjust for potential confounding. Over nine months, MMT substantially improved QALYs of HIV/AIDS patients (0.076 QALY [0.066-0.084]). The increments in QALY were large and stabilized in those patients taking antiretroviral treatment and abstinent to drug use. For one QALY gained, the MMT program would cost US$3745.3, approximately 3.2 times Vietnam GDP per capita in 2009. The cost-effectiveness of MMT intervention was robust against HIV advanced status or co-morbidity, e.g., TB treatment, but it might not be cost-effective for those patients who continued to use drug. Findings of this study indicate that providing MMT for HIV-positive drug users is a cost-effective intervention in Vietnam. Integrating MMT to HIV/AIDS care and treatment services would be beneficial in injection-driven HIV epidemics.

    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.

    Opioid maintenance treatment (OMT) is the most widely used treatment for opioid dependence. Maintenance programmes differ in various aspects and may also change over time. This paper investigates the changes in treatment practices within a national OMT programme during a 10 year period (2002-2011), especially with regard to the prescribing of methadone and buprenorphine. Data (n=34,001) were collected by annual assessments questionnaires. In 2002, only 16% of the OMT patients received buprenorphine as their maintenance medication. By 2011 this percentage had increased significantly (p<.001) to 50.3%. In the same period the number of patients more than tripled (from 1,984 to 6,640, p<.001), and programme attrition rates decreased (p=.020). This relatively rapid shift is a part of the increasing reliance of addiction medicine upon a range of medications administered by different routes which has not been previously charted within a national treatment programme.

    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.

    Background Compliance with methadone maintenance treatment (MMT) in China is poor. Objective To evaluate the effects of adjunctive contingency management (CM) on the efficacy of methadone maintenance treatment (MMT) in patients with opioid dependence. Hypothesis A 12-week prize-based contingency management (CM) intervention can increase the retention and compliance of heroin abusers to standardized MMT programs in Shanghai. Methods 160 heroin-dependent patients from three voluntary MMT clinics in Shanghai were randomly assigned to a treatment as usual group (MMT, n=80) and an intervention group (MMT+CM, n=80). Daily use of methadone was recorded and urine drug tests were conducted weekly during the first 12 weeks and then at week 16, week 20 and week 24. Results The 12-week retention rates for the intervention (MMT+CM) and treatment-as-usual (MMT) groups were both quite high: 87.5% and 86.2%, respectively. The average durations of using methadone in the two groups were equal (70 days versus 71 days, respectively). There was a non-significant increase in the mean longest drug-free period (7.4 weeks versus 6.5 weeks) and in the mean number of negative urine tests (7.9 versus 7.6). Secondary analysis of the 24-week outcomes (12 weeks after termination of the adjunctive CM treatment) also found no significant differences between the groups. Among those who remained in the program the severity of addiction as assessed by the Addiction Severity Index decreased dramatically over the 24 weeks but, again, there were no significant differences in the addiction measures between those in the intervention group and those in the treatment-as-usual group. Conclusion Prize-based CM is not effective in improving the retention and compliance of heroin abusers to MMT in Shanghai. The main reasons for failure to replicate western studies were the unexpectedly high baseline rates of compliance in this sample (86%) and the relatively weak financial incentives provided by the CM program

    Methadone maintenance treatment (MMT) is safe and effective for heroin addiction, but the neural basis of the length effects of long-term MMT on brain activity during craving in former heroin addicts is unclear. This study explored it by comparing the brain activations of heroin addicts with different length of MMT during pictorial presentation of heroin-related cue. Fifteen male former heroin addicts successfully treated by MMT less than 1 year (Group A), 15 matched patients with 2-3 year MMT (Group B) and 17 healthy controls underwent functional magnetic resonance imaging while heroin-related and neutral stimuli were present to them. Subjective cue-elicited craving was measured with visual analog scale before and after imaging. Then, partial correlation analysis to reveal the relationship between drug-related blood oxygen level dependent (BOLD) signal intensity and heroin or methadone use history. Finally, self-reported craving was not different between Group A and B before and after scanning. Compared with Group A, Group B had a significant reduced brain activity to heroin-related minus neural cues in the bilateral caudate. After controlling for the variable heroin use history, the drug-related BOLD signal intensity in the bilateral caudate was negatively correlated with MMT duration and total methadone consumption. When MMT history was controlled, the drug-related activity intensity in right caudate had a positive correlation with heroin daily dosage. Long-term MMT may improve heroin-craving response by modulating the impaired function in the bilateral dorsal striatum caused by former heroin use.

    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

    Background: Sleep disturbance is a common complaint of patients undergoing methadone maintenance therapy (MMT). There are limited studies about the effect of different treatments on insomnia due to MMT. In this study, we evaluated the effect of cognitive-behavioral treatment for insomnia (CBTI) on sleep disorders in patients undergoing MMT. Methods: Twenty-two patients with insomnia due to MMT (aged 18-60 years) participated in this randomized double-blind clinical trial. The intervention group received CBTI from a clinical psychologist for 8 weeks, whereas the control group received behavioral placebo therapy (BPT). The duration of individual sessions was 45 minutes, which was conducted once a week. The primary outcome was sleep disturbance assessed with Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using SPSS software version 19. Results: Eleven patients were assigned to each group. Two groups were matched according to demographic characteristics (age, marital status, education, and daily methadone doses). Although PSQI score was significantly reduced during weeks 5 and 8 after both interventions, there was a significant difference in intervention versus time interaction (P<0.02). The effects of CBTI versus placebo were significantly different (P<0.001). The time course was also significant (P<0.001). Conclusion: This study showed that CBTI is more effective than BPT in overall sleep quality. We recommend further studies, with a larger sample, on CBTI in patients undergoing MMT. PMID:26379345

    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.

    STAR, a methadone clinic in Portland, Oregon employs a psychoeducational approach in an attempt to provide coherent, comprehensive treatment in meeting diverse client needs. Two hundred and thirty-eight STAR clients completed a 133 item survey as part of an evaluative review of the efficacy of the psychoeducational model. Clients were asked about their perceived treatment needs and expectations, drug use, criminality, mental and physical health, social and economic stability, and their sense of self-worth and life satisfaction. Respondents reported that receiving methadone was the most useful and best liked aspect of treatment, followed by individual counseling, and education and skill classes. Clients indicated low rates of criminal behavior and drug use, but acknowledged high rates of psychological symptoms including depression, anxiety, and irritability, and rated as very important the need to reduce drug use and to improve health, to achieve a sense of life satisfaction, to enhance feelings about self and relationships, especially those with their children. A majority of the respondents had less than adequate income, and a substantial minority had less than a high school education. Longer time in treatment at STAR was associated with reduced heroin and cocaine use and improvements in social, economic and legal realms. The discussion focuses on implications for methadone treatment in general and possible modifications of the STAR program.

    There is increasing concern over whether standard health care services, such as substance abuse treatment, adequately account for important cultural influences, yet studies focusing on the impact of cultural influences on substance abuse treatment continue to be limited. The current study prospectively examined the effects of two cultural factors (ethnic identity and spirituality) on substance abuse treatment outcomes among Hispanic American clients (N=114) enrolled in methadone maintenance treatment. In addition, this study examined whether a commonly studied treatment factor (i.e., self-efficacy) significantly influenced treatment outcomes. Higher levels of self-efficacy at intake were related to increased odds of reported heroin abstinence and a lower number of drugs used at 1-year follow-up. Greater levels of ethnic identity were related to a greater number of drugs used at follow-up. No significant effects were found for spirituality.

    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) has become an important modality of substitution treatment for opioid addicts in China since 2006. However, data are limited regarding the change in sexual function from heroin use to MMT and the influence of sexual dysfunction (SD) during MMT on patient's life and treatment. Face-to-face in-depth interviews were conducted with 13 male and 14 female MMT patients, five of their partners, and three clinicians. The interviews took place in four MMT clinics in Guangdong Province between August 2010 and February 2011. The patients and their partners were asked separately for their perceptions of patient's sexual function during MMT, and the influence of SD on personal/family life and treatment. The main SD problems patients perceived were libido inhibition and decreased sexual pleasure. Methadone was thought to have a stronger inhibition effect on sexual desire than heroin. SD decreased quality of patient's sexual life and damaged intimate relationships. There was a gender difference in coping with SD. Men generally tended to refuse, escape, or alienate their partners. Women tended to hide sexual listlessness, endure sexual activity and tried to satisfy their partners. SD might increase risk of voluntary dropout from treatment and illicit drug use during treatment. Patients with SD did not get any effective therapy from clinicians and they also lacked skills on coping with SD-related problems. Sexual dysfunction prevented patients from reconstructing a normal intimate relationship, and affected stability of maintenance treatment. Response to patient's SD and SD-related problems from clinicians was inadequate. There is a need to develop a clinical guide to deal with both SD itself and SD-related problems. PMID:23092392

    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.

    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.

    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

    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.

    Illicit drug trade has re-emerged in China since 1979 and the number of drug addicts had increased. Syphilis is mainly spread through sexual contact and blood. The incidence of syphilis is high among drug users. Methadone maintenance treatment (MMT) clinics have been implemented in China since 2004. The aim of this study was to estimate the prevalence and risk factors of syphilis among drug users at MMT clinics in China between 2004 and 2013. Chinese and English databases (CBM, CNKI, Weipu, Pubmed) of literature were searched for studies reporting syphilis among drug users in MMT clinics from 2004 to 2013. The prevalence estimates and risk factors were summarized through a systematic review and meta-analysis of published literatures. In all, 29 eligible articles with a total of 8899 drug users, were selected in this review. The pooled prevalence of syphilis infection was 7.78% (95%CI: 5.83%-9.99%). The meta-analyses demonstrated significant differences in syphilis infection rates between men and women (OR = 0.34 [95%CI: 0.26-0.45]) but not between drug users and non-intravenous drug users (OR = 0.82 [95%CI: 0.51-1.32]). Enhanced detection of syphilis and health promotion is warranted in MMT clinics in China.

    Background The Ministry of Health, Treatment and Medical Education of Iran has recently announced an estimated figure of 200,000 injecting drug users (IDUs). The aim of this study was to pilot a national program using demographics, types of drug abuse and prevalence of blood-borne infections among IDUs. Methods: In order to elicit data on demographics, types of drug abuse and prevalence of blood-borne infections among IDUs, a questionnaire was designed in the Bureau of Mental-Social Health and Addiction in collaboration with Iran’s Drug Control Headquarters of the Police Department. Therapeutical alliance of addiction in Shafagh Center was based on Methadone Maintenance Therapy (MMT). Results: Among 402 reported IDUs most of them were male, single and in age range of 20 to 39 years old with 72.7% history of imprisonment. Most of them had elementary and high school education and a history of addiction treatment. The majority were current users of opioid, heroin and crack. The prevalence of blood-borne infections was 65.9% and 18.8% for HCV and HIV/AIDS infections, respectively. Conclusion: Prevention programs about harm reduction, treatment and counseling should include young IDUs as a core focus of their intervention structure. PMID:23967426

  1. The relationship between self-reported substance use and psychiatric symptoms in low-threshold methadone maintenance treatment clients

    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

    Methadone is a synthetic opioid that binds to the κ-opioid receptor with a low affinity. This study tested the hypotheses that the genetic polymorphisms in the κ-opioid receptor 1 (OPRK1) gene region are associated with methadone treatment responses in a Taiwan methadone maintenance treatment (MMT) cohort. Seventeen single nucleotide polymorphisms (SNPs) in OPRK1 were selected and genotyped on DNA of 366 MMT patients. Six SNPs from rs7843965 to rs1051660 (intron 2 to exon 2) were significantly associated with body weight (P < 0.007). A haplotype of 4 SNPs rs7832417-rs16918853-rs702764-rs7817710 (exon 4 to intron 3) was associated with bone or joint aches (P ≤ 0.004) and with the amount of alcohol use (standard drinks per day; global P < 0.0001). The haplotype rs10958350-rs7016778-rs12675595 was associated with gooseflesh skin (global P < 0.0001), yawning (global P = 0.0001), and restlessness (global P < 0.0001) withdrawal symptoms. The findings suggest that genetic polymorphisms in OPRK1 were associated with the body weight, alcohol use, and opioid withdrawal symptoms in MMT patients.

    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

    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.

  7. 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.

    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.

    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

    SUMMARY Insomnia afflicts many individuals, but particularly those in chronic methadone treatment. Studies examining sleep deprivation (SD) have begun to identify sleep restoration processes involving brain bioenergetics. The technique [31]P magnetic resonance spectroscopy (MRS) can measure brain changes in the high-energy phosphates: alpha-, beta-, and gamma-nucleoside triphosphate (NTP). In the present study, 21 methadone-maintained (MM) and 16 control participants underwent baseline (BL), SD (40 wakeful hrs), recovery1 (RE1), and recovery2 (RE2) study nights. Polysomnographic sleep was recorded each night and [31]P MRS brain scanning conducted each morning using a 4T MR scanner (dual-tuned proton/phosphorus headcoil). Interestingly, increases in total sleep time (TST) and sleep efficiency index (SEI) commonly associated with RE sleep were not apparent in MM participants. Analysis of methadone treatment duration revealed that the lack of RE sleep increases in TST and SEI were primarily exhibited by short-term MM participants (methadone<12 months), while RE sleep in long-term MM (methadone>12 months) participants was more comparable to control participants. Slow wave sleep increased during RE1, but there was no difference between MM and control participants. Spectral power analysis revealed that compared to control participants; MM participants had greater delta, theta, and alpha spectral power during BL and RE sleep. [31]P MRS revealed that elevations in brain beta-NTP (a direct measure of ATP) following RE sleep were greater in MM compared to control participants. Results suggest that differences in sleep and brain chemistry during RE in MM participants may be reflective of a disruption in homeostatic sleep function. PMID:19775835

    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.

    Opioid-induced constipation (OIC) is one of the major side effects in patients receiving methadone maintenance treatment (MMT). Quite often, constipation becomes a factor significantly affecting therapeutic options and choices. Currently used approaches are symptomatic and in many cases ineffective. At the same time, it is well known that the gastrointestinal system is a subject for psychosomatic influences. In this case report, we describe an unexpected outcome of placebo administration in a patient suffering from OIC since her participation in MMT. The patient participated in a triple-blind randomised placebo-controlled trial of naloxone for treatment of OIC. As part of the study crossover design, the patient received 1 week of placebo followed by 1 week of naloxone, and had significant improvement in her bowel functioning when receiving placebo, then returned to baseline during the second week of the study.

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

    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

    Background Despite evidence of low transfer of methadone into breast milk and the potential physical and psychological benefits that breastfeeding offers for methadone-exposed mothers and infants, the rate of breastfeeding initiation in this population is about half that reported nationally. This study describes the perceptions surrounding breastfeeding decisions and management among pregnant and postpartum women taking methadone. Methods Seven pregnant women and four postpartum women enrolled in methadone maintenance programs participated in semi-structured, audio-taped interviews and focus groups, respectively, about their breastfeeding experiences. Transcripts were analyzed and coded using qualitative content analysis. Results Three major content categories were indentified: (1) fears, barriers and misconceptions about breastfeeding while taking methadone; (2) motivation and perceived benefits of breastfeeding; and (3) sources of information, support, and anxiety about general breastfeeding management and breastfeeding while taking methadone. Lack of support from the healthcare community and misinformation about the dangers of combining breastfeeding and methadone therapy represented significant, yet modifiable, barriers to breastfeeding success in methadone-exposed women. Conclusions Interventions to increase the prevalence of breastfeeding among women taking methadone should address identified logistical, educational, and psychological barriers and consider inclusion of women themselves, partners, peers, and clinicians. In particular, clinicians who care for methadone-exposed mothers and infants should be educated on therapeutic communication, up-to-date breastfeeding contraindications, and the health benefits of breastfeeding in this population.

    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

  2. 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

    Methadone is a long-acting opioid agonist that is frequently prescribed as a treatment for opioid addiction. Almost all methadone maintenance patients are smokers, and there is a correlation between smoking habit and use of methadone. Methadone administration increases tobacco smoking, and heavy smokers use higher doses of methadone. Nevertheless, methadone maintenance patients are willing to quit smoking although their quit rates are low. Studies on nicotine-methadone interactions provide an example of the bedside-to-bench approach, i.e., observations in clinical settings have been studied experimentally in vivo and in vitro. In vivo studies have revealed the interplay between nicotine and the endogenous opioid system. At the receptor level, methadone has been shown to be an agonist of human α7 nAChRs and a non-competitive antagonist of human α4β2 and α3* nAChRs. These drugs do not have significant interactions at the level of drug metabolism, and thus the interaction is most likely pharmacodynamic. The net effect of the interaction may depend on individual characteristics because pharmacogenetic factors influence the disposition of both methadone and nicotine. PMID:26231941

    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.

    The present study examines the factor structure of the existing Neuropsychological Impairment Scale (NIS) through the use of exploratory factor analysis (EFA). The NIS is a brief, self-report measure originally designed to assess neurocognitive impairment (NCI) by having patients rate a range of items that may influence cognitive functioning. Stabilized patients on methadone maintenance therapy (MMT; N=339) in New Haven, CT who reported drug- or sex-related HIV risk behaviors in the past 6 months were administered the full 95-item NIS. An EFA was then conducted using principal axis factoring and orthogonal varimax rotation. The EFA resulted in retaining 57 items, with a 9-factor solution that explained 54.8% of the overall variance. The revised 9-factor measure--now referred to as the Brief Inventory of Neuro-cognitive Impairment (BINI)--showed a diverse set of factors with excellent to good reliability (i.e., F1 α=0.97 to F9 α=0.73). This EFA suggests the potential utility of using the BINI in the context of addiction treatment. Further research should examine the utility of this tool within other clinical care settings.

    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.

    A rapid gas-liquid chromatographic assay is developed for the quantification of methadone (Mtd) and its major metabolite, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), in biological fluids of opiate addicts. After alkaline extraction from samples with lidocaine hydrochloride as internal standard, Mtd and EDDP are separated on SP-2250 column at 220 degrees C and detected with a thermionic detector. The chromatographic time is about 6 min. The relative standard deviations (R.S.D.) of Mtd and EDDP standards are between 1.5 and 5.5%. Most drugs of abuse (morphine, codeine, narcotine, cocaine, benzoylecgonine, cocaethylene, dextropropoxyphene etc) are shown not to interfere with this technique. The method has been applied to study the levels of Mtd and EDDP metabolite in serum, saliva and urine of patients under maintenance treatment for opiate dependence. EDDP levels were found higher than those of Mtd in urine samples from four treated patients, but lower in serum and undetectable in saliva. However, Mtd concentrations were higher in saliva than in serum.

    Background Methadone maintenance treatment (MMT) is widely recognized as an effective method of combatting narcotic addiction. MMT reduces heroin withdrawal symptoms and, thus, makes it possible to provide the psychological and social support that is essential to the rehabilitation of drug users. Aim Compare the severity of depressive symptoms in heroin users who are currently receiving MMT to that of heroin users who are not receiving MMT. Methods We administered the 13-item version of the Beck Depression Inventory (BDI-13) and a demographic history form to 929 heroin users who had been receiving MMT at nine methadone treatment clinics in three Chinese cities for an average of 9 months and to 238 heroin users who had enrolled in a MMT program at the centers but had not yet begun MMT. Results Seventy-nine percent (188/238) of the untreated individuals reported depressive symptoms compared to 68% (628/929) of the individuals receiving MMT (χ2=11.69, p<0.001). The median (interquartile range) BDI score in the untreated group was 10.4 (7.9-11.4) compared to 8.0 (5.7-11.6) in the MMT group (Z=2.75, p=0.006). In the MMT group, there was a negative correlation between the severity of reported depressive symptoms and the duration of participation in the MMT program (rs=-0.24, Z=2.88, p=0.004). Multivariate linear regression analysis showed that after adjusting for all demographic variables the treated group still had less severe depressive symptoms than the untreated group. After adjusting for the effect of MMT treatment, depressive symptoms were more severe in heroin users who self-reported poor family relationships (standardized regression coefficient β=0.118, t=6.56, p<0.001) and in those who were divorced (β=0.120, t=3.73, p<0.001). Conclusions Moderate to severe depressive symptoms are common in heroin users. MMT is associated with lower levels of depressive symptoms in heroin users, but prospective randomized controlled trials are needed to determine whether or

    Background Methadone maintenance treatment (MMT) is widely recognized as an effective method of combatting narcotic addiction. MMT reduces heroin withdrawal symptoms and, thus, makes it possible to provide the psychological and social support that is essential to the rehabilitation of drug users. Aim Compare the severity of depressive symptoms in heroin users who are currently receiving MMT to that of heroin users who are not receiving MMT. Methods We administered the 13-item version of the Beck Depression Inventory (BDI-13) and a demographic history form to 929 heroin users who had been receiving MMT at nine methadone treatment clinics in three Chinese cities for an average of 9 months and to 238 heroin users who had enrolled in a MMT program at the centers but had not yet begun MMT. Results Seventy-nine percent (188/238) of the untreated individuals reported depressive symptoms compared to 68% (628/929) of the individuals receiving MMT (χ2=11.69, p<0.001). The median (interquartile range) BDI score in the untreated group was 10.4 (7.9-11.4) compared to 8.0 (5.7-11.6) in the MMT group (Z=2.75, p=0.006). In the MMT group, there was a negative correlation between the severity of reported depressive symptoms and the duration of participation in the MMT program (rs=-0.24, Z=2.88, p=0.004). Multivariate linear regression analysis showed that after adjusting for all demographic variables the treated group still had less severe depressive symptoms than the untreated group. After adjusting for the effect of MMT treatment, depressive symptoms were more severe in heroin users who self-reported poor family relationships (standardized regression coefficient β=0.118, t=6.56, p<0.001) and in those who were divorced (β=0.120, t=3.73, p<0.001). Conclusions Moderate to severe depressive symptoms are common in heroin users. MMT is associated with lower levels of depressive symptoms in heroin users, but prospective randomized controlled trials are needed to determine whether or

    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

    Depression and opiate-use disorders (abuse, dependence) often co-occur, each condition complicating the course and outcome of the other. It has been recommended that clinicians prescribe antidepressant therapy for mood symptoms in patients with active substance-use disorders, but whether antidepressants are effective in this specific population is not entirely clear. Therefore, the aim of this study was to examine the efficacy of antidepressants in patients with unipolar major depressive disorder (MDD) and/or dysthymic disorder (DD) with comorbid opiate-use disorders currently in methadone maintenance treatment (MMT). Medline/PubMed publication databases were searched for randomized, double-blind, placebo-controlled trials of antidepressants used as monotherapy for the treatment of MDD/DD in patients with comorbid opiate-use disorders currently in MMT. The search was limited to articles published between January 1, 1980, and June 30, 2010 (inclusive). Four manuscripts were found eligible for inclusion in our analysis (n = 317 patients). We found no statistically significant difference in response rates between antidepressant and placebo therapy in trials of MDD/DD patients with comorbid opiate-use disorders currently in MMT (risk ratio for response, 1.182; 95% CI: 0.822-1.700; P = 0.366). These results show no difference in the depressive outcome of patients with comorbid opiate-use disorders on MMT whether they are on medication or placebo. Future studies examining the effectiveness of antidepressants while controlling for several variables such as psychosocial treatment and assessing the specific classes of antidepressants are needed.

    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.

    2009-09-01

    This essay reviews four texts which critically analyse methadone maintenance therapy using Foucault as a key theoretical framework: [Friedman, J., & Alicea, M. (2001). Surviving heroin: Interviews with women in methadone clinics. Florida: University Press of Florida], [Bourgois, P. (2000). Disciplining addictions: The bio-politics of methadone and heroin in the United States. Culture Medicine and Psychiatry, 24, 165-195], [Bull, M. (2008). Governing the heroin trade: From treaties to treatment. Ashgate: Aldershot], and [Fraser, S., & valentine, k. (2008). Substance & substitution: Methadone subjects in liberal societies. New York: Palgrave Macmillan]. Taken together these works demonstrate one trajectory in the development of critical drug studies over the past decade. While all four view MMT as a regulatory technology which aims to create productive and obedient subjects, their understandings of the power relations of the clinic are quite distinct. The first two texts emphasise the social control of drug users, the third, issues of governmentality and liberal political practice, while the fourth engages with ontological questions about substances themselves. Thus while Foucauldian analysis has become familiar in social studies of drugs and alcohol, new uses for its conceptual tools continue to emerge.

  20. The geographic distribution patterns of HIV-, HCV- and co-infections among drug users in a national methadone maintenance treatment program in Southwest China

    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

    The number of opiate addicted patients treated with opioid replacement therapy is continuously increasing. In Germany, 57.7% of these patients are treated with methadone and 18.6% with buprenorphine. This maintenance therapy provides several advantages while addicted pregnant women and their foetus have a high benefit from appropriate replacement therapy. However, the recommendations concerning breast feeding during an opioid replacement therapy are discussed controversially, because methadone as well as buprenorphine accumulate in breast milk. This accumulation might cause damages to the newborn's health; so, child benefits of breast feeding have to be balanced with possible health risks.This review provides an overview of a selective literature search based on the PubMed-database and german consensus recommendations. Used search terms included: (methadone*) AND (breastfeeding OR lactation), (methadone*) AND (human milk), (buprenorphine*) AND (breastfeeding OR lactation) and (buprenorphine*) AND (human milk).According to the available literature, addicted women, substinated with methadone or buprenorphine are allowed to breast feed their newborns. The advantages of breast feeding prevail the risks of an infant opiate intoxication caused by methadone or buprenorphine.

    2010-01-01

    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.

    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

    There are currently over 7000 patients enrolled in opioid maintenance treatment (OMT) programs in Norway. A rise in methadone-related deaths proportional to increasing methadone sales over the period 2000-2006 has been observed, but the causative factors for these fatalities have been elusive. In the present study, individual characteristics, methadone concentrations and additional toxicological findings were analyzed. Methadone intoxication deaths (n = 264) were divided into 3 groups according to toxicological findings in whole blood: group 1 - methadone detected alone, or together with one additional drug at low or therapeutic levels, or a low concentration of ethanol (<1 g/L) (n = 21); group 2 - multiple additional drugs/substances detected below lethal levels (n = 175); group 3 - one or more additional drugs/substances detected at lethal levels, or ethanol >3 g/L (n = 55). Methadone blood concentrations in decedents who had been enrolled in OMT were higher than for decedents not in treatment, in all groups. Blood methadone concentrations around 1 mg/L were present in fatal multi-drug intoxications in OMT patients. Results suggest that some patients may be at risk of dying when combining therapeutic concentrations of methadone with other psychoactive substances. Somatic disease was a common finding among deceased OMT patients. Concentrations in methadone users not enrolled in OMT were predominantly between 0.3 and 0.4 mg/L and were not related to the presence of other drugs. However, methadone concentrations below 0.1 mg/L may be associated with intoxication following methadone use, both alone and in combination with other drugs. Younger male users (mean age 34 years) seemed to have a higher susceptibility to methadone intoxication.

    AIMS—To examine whether hyperphagia is a clinically significant problem in infants born to women receiving methadone maintenance.
METHODS—The volume of feeds, changes in infant body weight, as well as occurrence of adverse clinical effects in infants withdrawing from methadone were studied during the first month of life. A retrospective chart review was conducted for all infants at San Francisco General between 1992 and 1995, born to women receiving methadone maintenance during their pregnancy. Forty four infants were identified and the data obtained from hospital medical records. The daily oral intake of these infants was recorded during the first month of life. The incidence of hyperphagia (oral intake> 190 cc/kg/day) was measured. Associations between infant oral intake and maternal methadone dose were studied using correlation analysis as well as Anova for repeated measures. Adverse clinical symptoms were also recorded. A subset of premature infants was studied separately.
RESULTS—The incidence of hyperphagia was 26% by day 8 and 56% by day 16 of life in the infants. Hyperphagia was not associated with maternal methadone dose or with infant withdrawal scores. Infants who were hyperphagic lost significantly more weight during the first week of life than those who were not. Despite significantly greater intake, the hyperphagic infants did not gain weight more rapidly during the first month of life compared with those infants with lower oral intake. Infants who were hyperphagic (maximum intake of 290 cc/kg/day) did not experience increased vomiting, aspiration, diarrhoea, or abdominal distention.
CONCLUSIONS—Hyperphagia is commonly found in infants withdrawing from methadone and can be persistent in a significant number. Hyperphagia was not associated with either increased neonatal weight gain or with adverse gastrointestinal consequences. Hyperphagia may occur in infants withdrawing from methadone who have high metabolic demands due to clinical

    In order to study possible interactions between opioids and cigarette smoking, we examined the effects of oral methadone administration on the smoking behavior of five male methadone-maintenance patients. Isolated subjects smoked their regular brand of cigarettes ad libitum in a naturalistic laboratory environment while reading or watching television. Ninety minutes before each daily 2-hr smoking session subjects received either placebo, dextromethorphan (a taste blind) or one of three doses of methadone, 0.5, 1.0 or 2.0 times their regular maintenance dose (40-60 mg). Each subject received each treatment five times, in a mixed order across days. Methadone pretreatment resulted in a dose-related increase in the number of cigarettes smoked per session (from a mean of 2.8 after placebo to 5.6 after the high dose of methadone). The total time spent puffing during the session increased from a mean of 27 sec after placebo to 74 sec after the high dose of methadone. CO levels in expired air (a measure of actual smoke inhalation) showed corresponding dose-related increases. Methadone administration also resulted in dose-related decreases in pupil diameter and increases in subjective ratings of smoking satisfaction and dose-strength. Dextromethorphan had no significant effects on any measure of smoking behavior or subjective response. The results demonstrate that methadone can produce substantial increases in cigarette smoking and may have implications regarding the proposed role of endogenous opioids in the smoking process.

    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

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.

    A 7-year followup of three male samples of 1971-1973 methadone maintenance admissions was conducted: a random sample of 100; a sample of 136 who had a minimum of 30 months remaining on civil addict parole status at the time of methadone entry; and a matched sample of 136 not on parole. Ninety percent of those not decreased were interviewed. The overall sample spent 58% of the nonincarcerated follow-up interval on methadone. This resulted in a large decline in daily heroin use and associated criminal behavior measures. The addition of parole supervision with urine testing resulted in only marginal improvements in behavior over that attributable to maintenance alone; however, the parole status did significantly reduce the length of intervals of daily heroin use both prior and subsequent to methadone entry.

    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.

    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.

    This study aimed at develop and validate the procedure for collecting exhaled breath for drug testing. Patients receiving methadone maintenance treatment were recruited for the study. Methadone levels were measured using liquid chromatography- electrospray-tandem mass spectrometry. The sampling device was based on a 47-mm C(18) filter and used under pressure to aid flow through the filter. The mouth was rinsed before sampling, and the device was constructed to protect against any saliva contamination. Methadone was present in breath samples before and after the daily intake of methadone. The mean (± SD) pre-dose level was found to be 135 ± 109 pg/min (n = 48, median 121). The exhaled methadone increased after dose intake. Saliva levels of methadone were high in comparison with exhaled breath levels. Saliva contamination was suspected in about 10% of the collected samples. Similar results were obtained using 1, 3, and 10 min sampling times. The inter- and intraindividual variability were found to be similar and in the order of 50%. Alternative sampling using XAD-2 beads and solid-phase microextraction fiber was found to be possible and enables sampling with low back pressure and with no need for pump assistance. The presented results confirm that breath testing is a new possibility for the detection of drugs of abuse.

  18. Gender differences in pharmacokinetics and pharmacodynamics of methadone substitution therapy

    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.

Although 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. 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.

    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.

    To assess the effects of chronic methadone administration on locomotor, social, and eating behavior od drug-native individuals under circumstances approximating those of methadone "maintenance" clinics, we gave single, daily oral doses of methadone to 5 Macaca radiata monkeys living in a social group. We obtained motor activity counts automatically during 6 weeks of baseline, 10 weeks of drug administration, and 3 weeks of post-drug abstinence. Social behaviors of association, dominance, submission, and sexuality were counted 5 days per week, and animal weights, food eaten and food-reinforced work were recorded. Plasma methadone levels were near those achieved in mechadone clincs. Methadone produced mixed stimulation and sedation in the daytime, with stimulation predominating for 4 hrs following administration. At night the subjects moved less while taking the drug. Associative behaviors were reduced by methadone, but dominance, submission, and sexual behaviors were not altered. The monkeys ate less while taking the drug, losing weight and working less for food. In these primates methadone had significant stimulant properties, impaired important social behaviors, and reduced the potency of food as a reinforcer of work. The results are compared with methadone's effects upon humans.

    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

    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.

    Background. Sudden sensorineural hearing loss (SSHL) caused by opiate abuse or overuse has been well documented in the medical literature. Most documented case reports have involved either heroin or hydrocodone/acetaminophen. Recently, case reposts of methadone induced SSHL have been published. Case Report. We present the case of a 31-year-old man who developed SSHL after a methadone overdose induced stupor. He was subsequently restarted on methadone at his regular dose. On follow-up audiometry exams, he displayed persistent moderately severe sensorineural hearing loss bilaterally. Discussion. This case is notable because unlike all but one previously reported case, the patient—who was restated on methadone—did not make a complete recovery. Conclusion. Methadone overuse in rare cases causes SSHL. PMID:23983704

    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

    The effect of methadone treatment on the nonstress test (NST) was studied. Thirty narcotic-addicted gravidas on methadone maintenance underwent NSTs, performed and interpreted in a standard manner, before and 1 hour after taking the usual methadone dose. Urines were screened for commonly abused substances on the day of testing. Mean gestation when tested was 34 weeks and mean methadone dose was 26 mg/day. All urines were positive for methadone, six for cocaine, two for opiates, and one for amphetamines. The reactivity of the NSTs performed 1 hour after methadone ingestion was decreased significantly compared with that of tests performed before medication (P less than .04). Decreases in the frequencies of fetal movements and fetal heart rate accelerations were significant (P less than .001 and P less than .01, respectively). These results suggest that methadone treatment altered the morphology of the NST, which may limit the reliability of this test for determining fetal well-being in these high-risk gravidas if time of medication is not taken into consideration.

    2014-10-01

    Hurricane Sandy led to the closing of many major New York City public hospitals including their substance abuse clinics and methadone programs, and the displacement or relocation of thousands of opioid-dependent patients from treatment. The disaster provided a natural experiment that revealed the relative strengths and weaknesses of methadone treatment in comparison to physician office-based buprenorphine treatment for opioid dependence, two modalities of opioid maintenance with markedly different regulatory requirements and institutional procedures. To assess these two modalities of treatment under emergency conditions, semi-structured interviews about barriers to and facilitators of continuity of care for methadone and buprenorphine patients were conducted with 50 providers of opioid maintenance treatment. Major findings included that methadone programs presented more regulatory barriers for providers, difficulty with dose verification due to impaired communication, and an over reliance on emergency room dosing leading to unsafe or suboptimal dosing. Buprenorphine treatment presented fewer regulatory barriers, but buprenorphine providers had little to no cross-coverage options compared to methadone providers, who could refer to alternate methadone programs. The findings point to the need for well-defined emergency procedures with flexibility around regulations, the need for a central registry with patient dose information, as well as stronger professional networks and cross-coverage procedures. These interventions would improve day-to-day services for opioid-maintained patients as well as services under emergency conditions.

    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.

    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

    It has long been known that maternal addiction to opiates during pregnancy produces passive addiction in the newborn. When the synthetic opiate, methadone, became widely used for the treatment of heroin addiction, attention was focused on its possible reproductive and developmental toxicity. The clinical data clearly indicate that prenatal exposure to methadone produces a neonatal abstinence syndrome and that the symptoms, characterized by generalized CNS arousal, persist for as long as 4-6 month after birth. Long-term neurobehavioral follow-up studies to pre-school age have not found any obvious cognitive impairments or deficits in IQ. Some of the children, however, may be at risk for developing problems of fine motor coordination and attention deficit disorder that are likely to lead to poor school performance. These effects probably have complex origins and include primary drugs effects, postnatal/environmental interactions and genetic susceptibilities. Regardless of their interpretation, however, it is important to emphasize that from a risk/benefit point of view, most workers would agree that methadone maintenance poses far fewer hazards, both to the mother and her offspring, than continued abuse of heroin with its associated medical complications, psychosocial turmoil, but most importantly, risk of HIV infection. Because of their pharmacological relevance to the issue of human kinetics, it is hoped that the more recent animal studies of prenatal methadone exposure using the osmotic mini-pump will shed more light on the problem of developmental toxicity.(ABSTRACT TRUNCATED AT 250 WORDS)

    Methadone maintenance treatment (MMT) is the standard of care during pregnancy for opioid-dependency, showing efficacy in improving prenatal care and reducing risk of relapse. By design, however, MMT is only intended to prevent withdrawal thus facilitating cognitive behavioural interventions. In order to maximize the benefits of MMT, it is essential that methadone is both properly prescribed and that additional addiction treatment is concurrently administered. This study aims to determine the effectiveness of MMT engagement in high-risk pregnant women in reducing polydrug use by objective laboratory examination of neonatal meconium. Patients and Methods Over a 29-month period, the Motherisk Laboratory at the Hospital for Sick Children in Toronto analyzed meconium samples as per request by social services and hospitals for drugs of abuse. Results Of the 904 meconium samples received, 273 were tested for methadone with 164 positive and 109 negative for methadone. Almost half of the methadone positive samples (46.34%) were also positive for at least one other opioid compound, which did not differ statistically from the methadone-negative control samples (46.79%; Chi square test, p=0.94). No differences were found between the methadone positive and negative groups in rates of concurrent amphetamines, cocaine, cannabis, and alcohol use indicating a similar risk of polydrug use between pregnant women taking or not taking methadone in this population. Discussion The high rates of additional opioid and other drug use in the MMT group, suggest that MMT is failing this population of patients. It is possible that methadone doses during pregnancy are not appropriately adjusted for changes in pharmacokinetic parameters (e.g. blood volume, renal function) during the second and third trimesters. This may result in sub-therapeutic dosing creating withdrawal symptoms leading to additional substance use. Alternatively, these results may be demonstrating a substantial lack in

    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.

    The relationship between the quantity of methadone ingested by the pregnant mother, the quantity of methadone in maternal and neonatal body fluids, and the subsequent neonatal withdrawal course was studied. The severity of the neonatal withdrawal syndrome was found to be related to the total dose of methadone ingested by the mother during the last 12 weeks of pregnancy (p less than 0.02), the maternal dose of methadone at delivery (p less than 0.01), and the intrapartum serum methadone levels (p less than 0.01). The cord blood levels of methadone were consistently lower than the maternal serum levels. Amniotic fluid methadone levels were not constantly related to maternal or neonatal serum methadone levels. Concentrations of methadone 10 to 60 times greater than that of cord blood were found in neonatal urine.

    In a randomized double-blind study, the clinical efficacy of methadone vs. methadone and guanfacine was assessed in terms of evolution of opioid withdrawal symptoms during inpatient detoxification. A total of 144 patients were included and randomly allocated to three different treatment groups: methadone alone, and two combined treatment schedules (methadone plus 3 or 4 mg of guanfacine). No differences were observed among the three groups with regard to retention rate throughout the study period. Both therapies, methadone and methadone plus guanfacine, determined a slight increase in withdrawal scores when methadone was discontinued. However, guanfacine was unable to effectively control methadone-associated withdrawal symptoms. These results indicate that guanfacine does not effectively reduce the opioid withdrawal symptoms.

    Opioid substitution treatment (OST) for opioid dependence may be limited by adverse events (AEs). Increasing the range of therapeutic options optimizes outcomes and facilitates patient management. An international, multi-center, two-phase study investigated the efficacy and safety of slow-release oral morphine (SROM) versus methadone in patients receiving methadone therapy for opioid dependence. In phase 1 (two way cross-over, 11 weeks each period) patients were randomized to SROM or methadone oral solution. In phase 2 (25 weeks), patients continued treatment with SROM (group A) or switched from methadone to SROM (group B). In total, 211 out of 276 completed phase 1 and 198 entered phase 2 (n=95 group A, n=103 group B). Treatment with both SROM and methadone was well tolerated. However, the mean QTc-interval associated with methadone was significantly longer than that under SROM. Higher treatment satisfaction, fewer cravings for heroin, and lower mental stress were reported with SROM. This study adds a significant further weight of evidence that SROM is an effective and well tolerated long-term maintenance treatment for opioid dependence with a beneficial risk profile compared to methadone regarding cardiac effects and supports its clinical utility.

    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.

    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

    2012-01-01

    Background In France, the rapid scale-up of buprenorphine, an opioid maintenance treatment (OMT), in primary care for drug users has led to an impressive reduction in HIV prevalence among injecting drug users (IDU) but has had no major effect on Hepatitis C incidence. To date, patients willing to start methadone can only do so in a methadone clinic (a medical centre for drug and alcohol dependence (CSAPA) or a hospital setting) and are referred to primary care physicians after dose stabilization. This study aims to assess the effectiveness of methadone in patients who initiated treatment in primary care compared with those who initiated it in a CSAPA, by measuring abstinence from street opioid use after one year of treatment. Methods/Design The ANRS-Methaville study is a randomized multicenter non-inferiority control trial comparing methadone induction (lasting approximately 2 weeks) in primary care and in CSAPA. The model of care chosen for methadone induction in primary care was based on study-specific pre-training of all physicians, exclusion criteria and daily supervision of methadone during the initiation phase. Between January 2009 and January 2011, 10 sites each having one CSAPA and several primary care physicians, were identified to recruit patients to be randomized into two groups, one starting methadone in primary care (n = 147), the other in CSAPA (n = 48). The primary outcome of the study is the proportion of participants abstinent from street opioids after 1 year of treatment i.e. non-inferiority of primary care model in terms of the proportion of patients not using street opioids compared with the proportion observed in those starting methadone in a CSAPA. Discussion The ANRS-Methaville study is the first in France to use an interventional trial to improve access to OMT for drug users.

    Longer retention in drug abuse treatment is associated with better patient outcomes and research indicates the first 12 months of methadone treatment are critical to patient success. Nevertheless, large-scale multi-site longitudinal studies over the past three decades indicate that the majority of patients drop out during the first year of methadone treatment. Through an examination of 42 qualitative interviews with patients prematurely discharged from six methadone treatment programs in Baltimore, this paper highlights factors patients describe as contributing to their reasons for being discharged within the first 12 months of the treatment. The two most consistent themes are program-related factors and incarceration. The former factors are richly described through patients’ words and underscore the ways in which patients’ perceptions of control exerted by the program and by the medication and misunderstandings of program structure can lead to premature discharge. Patients’ reasons for discharge were compared to counselors’ reasons as indicated in discharge summary forms. An analysis of the patterns of agreement and disagreement are presented. Patient-centered program and policy implications are discussed. PMID:19999682

  9. Methadone diversion as a protective strategy: the harm reduction potential of 'generous constraints'.

    PubMed

    Harris, Magdalena; Rhodes, Tim

    2013-11-01

    Methadone maintenance treatment is evidenced as a successful harm reduction initiative in regard to the prevention of blood borne viruses and other injecting related harms. This is attributable to reductions in heroin use and injecting equipment sharing incidents, yet the means by which these are achieved are rarely elaborated. Methadone diversion is predominantly presented in a negative light; associated with overdose and other harms. In our qualitative London-based study with 37 people who inject drugs, 35 on substitution therapies, we found that methadone self regulation and diversion played a prominent role in helping participants to manage their drug use, prevent withdrawal, cement social relationships, and inadvertently protect against hepatitis C transmission. The ability of participants to enact these 'indigenous harm reduction strategies' was constrained to various degrees by their treatment dosing protocols. In this article we explore the strategies participants enacted with methadone, the role of 'generous constraints' in this enactment and the associated production and reduction of risk. In order to reengage people who inject drugs with harm reduction interventions, it is necessary for initiatives to take stock of the indigenous strategies that individuals are already utilising and - in the case of methadone self regulation - support them by the implementation of more generous constraints.

    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.

    Aims To measure the interdose milk to plasma ratio (M/P) of R- and S-methadone during multiple dosing in lactating mothers taking medium to high doses of methadone (> 40 mg daily), and to assess likely infant exposure. Methods Eight mother/child pairs were studied, initially during their postpartum hospital stay (immature milk), and where possible again after 15 days (mature milk). The women were on a methadone maintenance programme with daily doses of ≥40 mg day−1. Venous blood was collected at 0, 1, 2, 4, 6, 8, 12, and 24 h and milk was collected from both breasts at 0–4, 4–8, 8–12, 12–16, 16–20, and 20–24 h after dose. R- and S-methadone were quantified by h.p.l.c. The areas under the plasma and milk concentration-time curves (AUC) were estimated and M/PAUC was calculated. The relative infant dose of both enantiomers was estimated as the product of drug concentration in milk and an average daily milk intake of 0.15 l kg−1. Results For immature milk (n = 8) the M/PAUC for R-methadone was 0.68 (95% CI 0.48, 0.89) and for S-methadone 0.38 (0.26, 0.50). For mature milk (n = 2) the M/PAUCs for R-methadone were 0.39 and 0.54 and for S-methadone 0.24 and 0.30, respectively. The estimated doses of R- and S-methadone that would be received by the infant via immature milk were 3.5% (2.05, 5.03%) and 2.1% (1.3, 2.8%), respectively, of the maternal dose (assuming 50% of each enantiomer in the dose). The relative infant dose for R- plus S-methadone together was 2.8% (1.7, 3.9%). Conclusions Breastfeeding during medium to high dose methadone appears to be ‘safe’ according to conventional criteria because the dosage is < 10%. However because the absolute dose received by the infant is dependent on the maternal dose rate, the risk-benefit ratio should be considered for each individual case. The doses of methadone received via milk are unlikely to be sufficient to prevent the neonatal abstinence syndrome. PMID:11736879

  13. Methadone adverse reaction presenting with large increase in plasma methadone binding: a case series

    PubMed Central

    2011-01-01

    Introduction The use of methadone as an analgesic is on the increase, but it is widely recognized that the goal of predictable and reproducible dosing is confounded by considerable variability in methadone pharmacokinetics, and unpredictable side effects that include sedation, respiratory depression and cardiac arrhythmias. The mechanisms underlying these unpredictable effects are frequently unclear. Here, to the best of our knowledge we present the first report of an association between accidental methadone overexposure and increased plasma protein binding, a new potential mechanism for drug interactions with methadone. Case presentation We describe here the cases of two patients who experienced markedly different responses to the same dose of methadone during co-administration of letrozole. Both patients were post-menopausal Caucasian women who were among healthy volunteers participating in a clinical trial. Under the trial protocol both patients received 6 mg of intravenous methadone before and then after taking letrozole for seven days. One woman (aged 59) experienced symptoms consistent with opiate overexposure after the second dose of methadone that were reversed by naloxone, while the other (aged 49) did not. To understand the etiology of this event, we measured methadone pharmacokinetics in both patients. In our affected patient only, a fourfold to eightfold increase in methadone plasma concentrations after letrozole treatment was observed. Detailed pharmacokinetic analysis indicated no change in metabolism or renal elimination in our patient, but the percentage of unbound methadone in the plasma decreased 3.7-fold. As a result, the volume of distribution of methadone decreased approximately fourfold. The increased plasma binding in our affected patient was consistent with observed increases in plasma protein concentrations. Conclusions The marked increase in the total plasma methadone concentration observed in our patient, and the enhanced pharmacodynamic

    Methadone is not a new analgesic drug [69]. Several studies have demonstrated that methadone is a valid alternative to morphine, hydromorphone, and fentanyl for the treatment of cancer-related pain, and extensive reviews on the subject have been published in recent years [10,23,25,64,70,71]. Most people involved in pain therapy, however, are not well informed about the properties of methadone. The authors believe that the low cost of methadone paradoxically contributes to the limited knowledge of its characteristics and to the restricted therapeutic use of this drug. The low cost of methadone means there is little financial incentive for pharmaceutical companies to invest in research or to disseminate scientific information. Unfortunately, the lack of scientific information from pharmaceutical companies frequently results in a lack of knowledge on the part of physicians. Unless the existing approach changes, both culturally and politically, ignorance about methadone will persist among medical experts. The low cost of methadone, rather than being an advantage, will result in the limited exploitation of an effective drug.

    This prospective study (n=190) examined correlates of alcohol use from baseline data of a longitudinal trial conducted among moderate and heavy alcohol users receiving methadone maintenance therapy (MMT). The sample included MMT clients who were 18-55 years of age, and were receiving MMT from five large methadone maintenance clinics in the Los Angeles area. Half of the sample was heavy drinkers and nearly half (46%) reported heroin use. Using a structured questionnaire, correlates of heavy alcohol use included White and Hispanic ethnicity, and fair or poor physical health combined with older age (> or =50 years). We also found that MMT clients who were younger than 50 years, regardless of health status, were more likely to be heavy drinkers. Compared with moderate alcohol consumers, a greater number of heavy alcohol users also experienced recent victimization. To optimize MMT, alcohol screening should be part of routine assessment and alcohol treatment should be made available within MMT programs. Moreover, special consideration should be provided to the most vulnerable clients, such as the younger user, those with a long-term and current history of heavy drug use, and those victimized and reporting fair or poor health. In addition, promoting attention to general physical and mental health problems within MMT programs may be beneficial in enhancing health outcomes of this population.

    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.

    Background More than 50% of incarcerated individuals have a history of substance use, and over 200,000 individuals with heroin addiction pass through American correctional facilities annually. Opiate replacement therapy (ORT) with methadone or buprenorphine is an effective treatment for opiate dependence and can reduce drug-related disease and recidivism for inmates. Provision of ORT is nevertheless a frequently neglected intervention in the correctional setting. Objective and Methods We surveyed the 50 state; Washington, District of Columbia (DC); and Federal Department of Corrections' medical directors or their equivalents about their facilities' ORT prescribing policies and referral programs for inmates leaving prison. Results We received responses from 51 of 52 prison systems nationwide. Twenty-eight prison systems (55%) offer methadone to inmates in some situations. Methadone use varies widely across states: over 50% of correctional facilities that offer methadone do so exclusively for pregnant women or for chronic pain management. Seven states' prison systems (14%) offer buprenorphine to some inmates. The most common reason cited for not offering ORT was that facilities “prefer drug-free detoxification over providing methadone or buprenorphine.” Twenty-three states' prison systems (45%) provide referrals for some inmates to methadone maintenance programs after release, which increased from 8% in 2003; 15 states' prison systems (29%) provide some referrals to community buprenorphine providers. Conclusion Despite demonstrated social, medical, and economic benefits of providing ORT to inmates during incarceration and linkage to ORT upon release, many prison systems nationwide still do not offer pharmacological treatment for opiate addiction or referrals for ORT upon release.

    Individuals on methadone maintenance for the treatment of addiction (MM) are demonstrated to be hyperalgesic to cold-pressor pain in comparison to matched controls and ex-opioid addicts, a finding described as clinical evidence of opioid-induced hyperalgesia (OIH). Interestingly, opioids induce hyperalgesia via many of the same neuro-inflammatory and central sensitization processes that occur with the development of neuropathic pain. Evaluated in this study was the efficacy of a key pharmacotherapy for neuropathic pain, gabapentin (GPN), to reverse OIH in MM patients. Utilizing a clinical trial design and double blind conditions, changes in cold-pressor pain threshold and tolerance following a five-week trial of GPN (titrated to 2400mg/day) were evaluated at peak and trough methadone plasma levels in a well-characterized MM sample. Drug abstinence was encouraged via an escalating payment schedule, and compliance monitored via pill counts and GPN plasma levels; entered into the analyses were only those subjects compliant and abstinent throughout the study (approx 45%). Utilizing change scores from baseline, significant improvements in cold-pressor pain threshold and pain tolerance were observed at both peak and trough methadone levels (p < 0.05). Notably, drop-out rates due to medication side effects were low (2%) and the medication was well-tolerated. These results support that GPN, as prescribed for the treatment of neuropathic pain, is effective in decreasing OIH in patients who are abstinent and stable in methadone treatment. PMID:20163921

    Two studies were conducted to investigate the effectiveness of contingency management techniques in promoting punctual counseling attendance among methadone maintenance patients. In Study 1, 50 participants were recruited from an inner-city methadone maintenance program. Study 1 used an A-B-A design with baseline, intervention, and return-to-baseline phases. On-time attendance was reinforced during the intervention phase with a voucher that was redeemable for a draw out of a box containing 100 tokens with values varying from 0.00 dollars to 100.00 dollars. Methadone maintenance patients who exhibited poor attendance during baseline showed a significant positive response during the contingency management intervention phase. Study 2 used the same design as Study 1 except that the 52 participants were randomized into reinforcement groups that received either the variable rate of reinforcement as in Study 1 or a fixed value reinforcer of 3.25 dollars. As in Study 1, Poor Attenders significantly improved counseling attendance during the intervention. There were no differences between the variable and fixed reinforcement groups. Overall, results suggest that targeting Poor Attenders with contingency management techniques may be a cost-effective method of improving counseling attendance. Targeting Poor Attenders early in treatment may be especially important for improving treatment outcomes.

    Methadone has been defined as an agent to draw addicts out of the street life into "straight" society. However, the complementary perspective of the streets sees methadone as a new, widely available drug to be integrated into a subculture previously dominated by heroin. This article discusses the adaptation to methadone and its implications. (NQ)

    1977-01-01

    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

    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.

    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

    The aim of this study was to evaluate the effectiveness of an educational method of providing viral hepatitis education for methadone maintenance patients. 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.

    Nicotine-methadone interactions have been studied in human beings and in various experimental settings regarding addiction, reward and pain. Most methadone maintenance treatment patients are smokers, and methadone administration has been shown to increase cigarette smoking. Previous in vitro studies have shown that methadone is a non-competitive antagonist at rat α3β4 nicotinic acetylcholine receptors (nAChR) and an agonist at human α7 nAChRs. In this study, we used cell lines expressing human α4β2, α7 and α3* nAChRs to compare the interactions of methadone at the various human nAChRs under the same experimental conditions. A [(3) H]epibatidine displacement assay was used to determine whether methadone binds to the nicotinic receptors, and (86) Rb(+) efflux and changes in intracellular calcium [Ca(2+) ]i were used to assess changes in the functional activity of the receptors. Methadone displaced [(3) H]epibatidine from nicotinic agonist-binding sites in SH-EP1-hα7 and SH-SY5Y cells, but not in SH-EP1-hα4β2 cells. The Ki values for methadone were 6.3 μM in SH-EP1-hα7 cells and 19.4 μM and 1008 μM in SH-SY5Y cells. Methadone increased [Ca(2+) ]i in all cell lines in a concentration-dependent manner, and in SH-EP1-hα7 cells, the effect was more pronounced than the effect of nicotine treatment. In SH-EP1-hα4β2 cells, the effect of methadone was negligible compared to that of nicotine. Methadone pre-treatment abolished the nicotine-induced response in [Ca(2+) ]i in all cell lines expressing nAChRs. In SH-EP1-hα4β2 and SH-SY5Y cells, methadone had no effect on the (86) Rb(+) efflux, but it antagonized the nicotine-induced (86) Rb(+) ion efflux in a non-competitive manner. These results suggest that methadone is an agonist at human α7 nAChRs and a non-competitive antagonist at human α4β2 and α3* nAChRs. This study adds further support to the previous findings that opioids interact with nAChRs, which may underlie their frequent co

    Aim The interindividual variability in the dose required for effective methadone maintenance treatment (MMT) for opioid addiction may be influenced in part by genetic variations in genes encoding pharmacodynamic factors of methadone. This study was conducted to identify some of these variants. Materials & methods This study focused on 11 genes encoding components of the opioidergic (OPRM1, POMC and ARRB2), the dopaminergic (ANKK1 and DRD2) and the glutamatergic pathways (GRIN1 and GRIN2A), as well as the neurotrophin system (NGFB, BDNF, NTRK1 and NTRK2). The study includes 227 Israeli patients undergoing stable MMT. Results Out of the 110 variants analyzed, 12 SNPs (in BDNF, NTRK2, OPRM1, DRD2 and ANKK1) were associated with methadone dose (nominal p < 0.05). Of these SNPs, ANKK1 rs7118900 and DRD2 rs2283265 are known to affect gene expression. Logistic regression of five representative SNPs discriminated between individuals requiring a methadone dose of >120 mg/day and <120 mg/day (p = 0.019), and showed moderate sensitivity and specificity (AUC of 0.63 in receiver operating characteristic analysis). Conclusion This data should stimulate further research on the potential influence and clinical significance of these variants on MMT. PMID:23651024

    Despite the importance of counseling in methadone maintenance treatment, many patients do not take advantage of these services. Incentives for attending group counseling were offered to methadone-maintained patients during an orientation phase of treatment or during required attendance at a relapse group later in treatment. Upon attending each counseling session, patients could draw for prizes under an escalating draw system with a 50% probability that draws would result in a prize. Incentives included small (1dollar), moderate (5 dollars), and large (20 dollars) prizes, with chances of winning inversely related to prize costs, and a maximum possible total of 160 dollars per patient. It was anticipated that this policy would provide a relatively low-cost approach to improving counseling attendance in our methadone clinic. The incentive policy significantly increased the percent of counseling sessions attended (52% vs. 76%) and promoted periods of continuous attendance. These data further support the effectiveness of low-cost incentive programs in enhancing counseling attendance among methadone patients.

    Male and female Sprague-Dawley rats were given dl-methadone (5 mg/kg) for at least 3 months and then mated. The drug was continued throughout pregnancy and after delivery. The newly born pups were divided into two groups. One group was tested for in vivo methadone tolerance, while the animals in the othergroup were used to prepare organotypic cerebellar cultures. Various amounts of dl-methadone were added to the media of half of these cerebellum cultures. The effect of the drug in the medium was assessed by measuring explant outgrowth. Similar experiments were carried out with control animals. Statistical analysis of the data obtained in the in vivo portion of the experiment indicates that the pups of methadone-treated mothers tolerate methadone better than those of untreated mothers. The culture experiments revealed that the addition of methadone to the medium reduced explant outgrowth size and this was a dose-related effect. Also, there was significantly less outgrowth from explants prepared using pups of methadone-treated mothers as compared to the controls. There was no significant difference in the effect of methadone on the growth of cultures prepared from the methadone-tolerant and control animals.

    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

    This study evaluates concentrations of methadone in breast milk and plasma among a sample of methadone-maintained women in the immediate perinatal period. Twelve methadone-maintained, lactating women provided blood and breast milk specimens 1, 2, 3, and 4 days after delivery. Specimens were collected at the time of trough (just before methadone dose) and peak (3 hours after dosing) maternal methadone levels. Paired specimens of foremilk (prefeed) and hindmilk (postfeed) were obtained at each sampling time. Although there was a significant increase in methadone concentration in breast milk over time for the peak postfeed sampling time, t(22) = 2.40, P = .0255, methadone concentrations in breast milk were small, ranging from 21 to 314 ng/mL, and were unrelated to maternal methadone dose. Results obtained from this study contribute to the recommendation of breastfeeding for methadone-maintained women regardless of methadone dose. PMID:17478871

    BACKGROUND Methadone maintenance for heroin dependence reduces illicit drug use, crime, HIV risk, and death. Typical dosages have increased over the past few years, based on strong experimental and clinical evidence that dosages under 60 mg/day are inadequate and that dosages closer to 100 mg/day produce better outcomes. However, there is little experimental evidence for the benefits of exceeding 100 mg/day, or for individualizing methadone dosages. We sought to provide such evidence. METHODS We combined individualized methadone dosages over 100 mg/day with voucher-based cocaine-targeted contingency management (CM) in 58 heroin- and cocaine-dependent outpatients. Participants were randomly assigned to receive a fixed dose increase from 70 mg/day to 100 mg/day, or to be eligible for further dose increases (up to 190 mg/day, based on withdrawal symptoms, craving, and continued heroin use). All dosing was double-blind. The main outcome measure was simultaneous abstinence from heroin and cocaine. RESULTS We stopped the study early due to slow accrual. Cocaine-targeted CM worked as expected to reduce cocaine use. Polydrug use (effect-size h = .30) and heroin craving (effect-size d = .87) were significantly greater in the flexible/high-dose condition than in the fixed-dose condition, with no trend toward lower heroin use in the flexible/high-dose participants. CONCLUSIONS Under double-blind conditions, dosages of methadone over 100 mg/day, even when prescribed based on specific signs and symptoms, were not better than 100 mg/day. This counterintuitive finding requires replication, but supports the need for additional controlled studies of high-dose methadone. PMID:23195924

    This study examined the effects of contingent vs. non-contingent delivery of a methadone dose supplement on relapse to illicit opiate use in the context of a methadone outpatient detoxification program. Following a 3-week methadone stabilization period on 30 mg, patients (N = 39) were randomly assigned to a contingent, a non-contingent, or a control treatment group. All patients received identical gradual reductions in their assigned methadone dose. During the dose reduction period (weeks 4-11), members of the contingent (N = 13) and non-contingent groups (N = 13) could obtain daily methadone-dose supplements up to 20 mg, but contingent group members could obtain supplements only if their most recent urinalysis results were opiate negative. Control subjects (N = 13) did not have dose increases available. The contingent group presented significantly lower opiate-positive urines during weeks 8-11 (14% positive) of the detox than the non-contingent (38% positive) or control (50% positive) groups. Additionally, the availability of extra methadone improved treatment retention and increased clinic attendance above levels observed in the control group. The potential for further use of methadone's reinforcing properties in the treatment of opiate dependence is discussed.

    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

    The effects of oral methadone on respiration, ventilation, pupillary diameter, and plasma concentrations of estrone, estradiol, and progesterone were investigated in healthy nonpregnant women, 21 to 29 yr old. All women were in the follicular phase of the menstrual cycle. The study design was a randomized, double-blind, placebo-controlled trial. Six women received 15 mg methadone . HCl, and six received placebo. Alveolar ventilation and oxygen consumption before treatments correlated with plasma progesterone concentration (r2 = 0.85 and 0.68) but the slope and x-intercept of the ventilatory response to carbon dioxide curve did not. Female sex steroids in plasma were not affected by methadone. Mean elimination half-life of methadone from serum was 19 hr. Methadone-induced respiratory depression and miosis lasted more than 48 hr. The intensity of these changes was a linear function of the logarithm of the serum methadone concentration. Plasma progesterone concentration is an important determinant of resting ventilation and metabolism in the follicular phase of the menstrual cycle but endogenous progesterone does not protect women from the respiratory depressant effects of methadone.

    National data indicate that patients treated with buprenorphine for opiate use disorders are more likely to be White, highly educated, and to have greater incomes than those receiving methadone, but patterns of buprenorphine dissemination across demographic areas have not been documented in major metropolitan areas where poverty, minority populations and injection heroin use are concentrated. Rates of buprenorphine and methadone treatment are compared among areas of New York City defined by their income and ethnic/racial composition. Residential social areas (hereinafter called social areas) were defined as aggregations of ZIP codes with similar race/ethnicity and income characteristics, and were formed based on clustering techniques. Treatment rates were obtained for each New York City ZIP code: buprenorphine treatment rates were based on the annual number of buprenorphine prescriptions written, and the methadone treatment rate on the number of methadone clinic visits for persons in each ZIP code. Treatment rates were correlated univariately with ethnicity and income characteristics of ZIP codes. Social area treatment rates were compared using individual ANOVA models for each rate. Buprenorphine and methadone treatment rates were significantly correlated with the ethnicity and income characteristics of ZIP codes, and treatment rates differed significantly across the social areas. Buprenorphine treatment rates were highest in the social area with the highest income and lowest percentage of Black and Hispanic residents. Conversely, the methadone treatment rate was highest in the social area with the highest percentage of low income and Hispanic residents. The uneven dissemination of 0pioid maintenance treatment in New York City may be reflective of the limited public health impact of buprenorphine in ethnic minority and low income areas. Specific policy and educational interventions to providers are needed to promote the use of buprenorphine for opiate use disorders

    BACKGROUND It is suspected that there is a continuum of impairment among prenatally drug-exposed infants, such that opioid and/or poly-drug exposure confers the highest risk for adverse neonatal outcomes than other classes of substances or single substance exposures. Suitable control groups are difficult to identify. This study compared fetal neurobehavioral development and infant outcomes in offspring of three groups of pregnant women in drug treatment. Exposure groups include: Methadone + other illicit substances (MM+Poly) and two groups currently abstinent for poly drug exposures: Methadone only (MM/A) and Non-methadone (NM/A). METHODS Forty-nine women (19 MM+Poly, 18 MM/A, and 12 NM/A) underwent fetal monitoring at 36 weeks gestation at peak and trough levels of methadone (MM+Poly; MM/A) or at comparable morning and afternoon times (NM/A). Fetal heart rate (FHR), heart rate variability (FHRV) and motor activity (FM) data were collected. Infant measures included birth outcomes and Neonatal Abstinence Syndrome (NAS) assessment. RESULTS As compared to the NM/A group, cardiac measures were decreased in methadone-exposed fetuses at peak levels. FHR was significantly more suppressed in the MM+Poly group. FM was significantly lower in the MM/A versus the NM/A group at both peak and trough, indicative of more persistent exposure effects. The MM+Poly group delivered one week earlier and required NAS pharmacological treatment twice as often as the MM/A group. CONCLUSIONS Results support the notion that poly-drug exposure may potentiate the effects of methadone on the fetus and infant and highlights the need for intensified treatment for methadone-maintained women who abuse other substances.

    Objectives Methadone-related overdose deaths increased in the United States by 468% from 1999 to 2005. Current studies associate the nonmedical use of methadone with methadone-related deaths. This study describes medical examiner cases in rural Virginia in 2004 with methadone identified by toxicology and compares cases according to source of methadone. Methods In 2004, all intentional and unintentional poisoning deaths from the Office of The Chief Medical Examiner, Western District of Virginia, were reviewed to identify cases in which methadone was a direct or contributing cause of death. The Virginia Prescription Monitoring Program was reviewed for prescription opioids in the name of these identified decedents. Decedent participation in local opioid treatment programs (OTP) was also assessed. Results The source of methadone in the 61 methadone-related overdose deaths was mostly nonprescribed (67%), although 28% of decedents were prescribed methadone for analgesia. Only 5% of decedents were actively enrolled in an OTP. The majority of deaths were attributed to polysubstance overdose. Conclusions The majority of methadone overdose deaths in this study were related to illicit methadone use, rather than prescribed or OTP uses. Interventions to decrease methadone-related deaths should focus on reduction of nonprescription use of methadone. PMID:21844834

    Like all health care services, case management is a process that relies on information. Based on the experiences in implementing computer information systems in six hospital-based case management programs, several financial, technical, and management issues are reviewed. These issues, which are also relevant for other specialized hospital-based programs, include information priorities, user acceptance, quantifying data, data entry methods, data security, and systems integration. The lessons learned regarding these issues are discussed, and categories of software alternatives are presented.

    The effects of steady-state faldaprevir on the safety, pharmacokinetics, and pharmacodynamics of steady-state methadone and buprenorphine-naloxone were assessed in 34 healthy male and female subjects receiving stable addiction management therapy. 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.

    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

    2012-01-01

    The psychometric properties of the Iowa Personality Disorder Screen (IPDS) were examined in 150 methadone-maintained patients who completed measures of demographic, psychopathology, substance use, pain, and methadone maintenance treatment (MMT) characteristics. An exploratory factor analysis revealed a two-factor solution that explained 45 percent of the scale variance. The first factor captured internalizing tendencies, such as inhibition and hypersensitivity to others. The second factor comprised externalizing tendencies, such as impulsivity and insensitivity to others. The IPDS item subsets, derived factors, and the total score were significantly related to race/ethnicity but not sex. The effects of race/ethnicity were controlled statistically when the IPDS was compared to other measures of psychopathology, self-reported substance use, pain variables, and MMT characteristics. In general, the IPDS appears to be reliable and valid for use with methadone-maintained patients. The two-factor structure found in this study may have clinical utility and merits further investigation in other MMT samples. PMID:23398100

    Purpose This study explores the current QoL of opiate-dependent individuals who started outpatient methadone treatment at least 5 years ago and assesses the influence of demographic, psychosocial, drug and health-related variables on individuals’ QoL. Methods Participants (n = 159) were interviewed about their current QoL, psychological distress and severity of drug-related problems, using the Lancashire Quality of Life Profile, the Brief Symptom Inventory and the Addiction Severity Index. Potential determinants of QoL were assessed in a multiple linear regression analysis. Results Five years after the start of methadone treatment, opiate-dependent individuals report low QoL scores on various domains. No association was found between drug-related variables and QoL, but a significant negative impact of psychological distress was identified. Severity of psychological distress, taking medication for psychological problems and the inability to change one’s living situation were associated with lower QoL. Having at least one good friend and a structured daily activity had a significant, positive impact on QoL. Conclusions Opiate-dependent individuals’ QoL is mainly determined by their psychological well-being and a number of psychosocial variables. These findings highlight the importance of a holistic approach to treatment and support in methadone maintenance treatment, which goes beyond fixing the negative physical consequences of opiate dependence.

    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

    Objective The aim of this study was to examine the association of pain catastrophizing and pain coping strategies with characteristic pain intensity (an average of worst, least, and typical pain intensity in the past week) and recent pain-related disability (an average of three measures of past week pain interference) in opioid dependent patients enrolled in a methadone maintenance treatment program (MMTP) who reported recent pain. Design Cross-sectional survey. Patients One hundred and eight MMTP patients who reported recent pain. Measures Participants completed measures of demographics, pain status (i.e. “chronic severe pain” [pain lasting at least 6 months with at least moderate pain intensity or significant pain interference in the past week] vs. “some pain” [pain in the past week not meeting the threshold of chronic severe pain]), characteristic pain intensity, recent pain-related disability, somatization, depression, catastrophizing, and pain coping strategies. Results Catastrophizing explained a significant proportion of the variance in characteristic pain intensity (14%) and recent pain-related disability (11%) after controlling for demographics, pain status, somatization, and depression. Mirroring the findings of studies of non-opioid dependent chronic pain patients, greater catastrophizing was associated with greater pain intensity and increases in recent pain-related disability. On average, the chronic severe pain group reported higher levels of catastrophizing than the some pain group. Conclusion Consistent with studies of patients with chronic pain who are not opioid dependent, our findings emphasize the importance of assessing and addressing catastrophizing in MMTP patients with pain.

    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

    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

    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.

    In this article the familiar functioning of subjects addict to opioids included in a maintenance programme with methadone will be analyzed, trying to identify whether belonging to one type of family (family typology) or another, according to Olson's Familiar Functioning Model, is related to the level of deterioration or severity of addiction of the different areas associated to consumption . The sample is composed by 69 subjects (N=69) users of the Servicio de Atención a las Drogodependencias (SAD) in Centro de Servicios Sociales Comunitarios del Ayuntamiento de Alcalá de Guadaíra (Seville). In order to evaluate the functioning and the family typology of these subjects the Escala de Cohesión y Adaptación Familiar--CAF-1--Spanish version of FACES III was used. In order to evaluate the level of deterioration, the Spanish version of the 5th edition of the personal, clinical semistructured interview Addiction Severity Index--ASI4--was applied. The results indicate that the subjects included in balanced families present more addiction severity in two dimensions of the ASI: Alcohol and Employment/Support and are, moreover, the ones that take greater doses of methadone.

    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

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

    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.

    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.

    Despite the clear efficacy of methadone for opioid dependence, one less desirable phenomenon associated with methadone may be weight gain. We examined changes in body mass index (BMI) among patients entering methadone treatment. A retrospective chart review was conducted for 96 patients enrolled in an outpatient methadone clinic for ≥6 months. The primary outcome of BMI was assessed at intake and a subsequent physical examination approximately 1.8±0.95 years later. Demographic, drug use and treatment characteristics were also examined. There was a significant increase in BMI following intake (p < 0.001). Mean BMIs increased from 27.2±6.8 to 30.1±7.7 kg/m2, translating to a 17.8-pound increase (10% increase in body weight) in the overall patient sample. Gender was the strongest predictor of BMI changes (p < 0.001), with significantly greater BMI increases in females than males (5.2 vs. 1.7 kg/m2, respectively). This translates to a 28-pound (17.5%) increase in females vs. a 12-pound (6.4%) increase in males. In summary, methadone treatment enrollment was associated with clinically significant weight gain, particularly among female patients. This study highlights the importance of efforts to help patients mitigate weight gain during treatment, particularly considering the significant health and economic consequences of obesity for individuals and society more generally.

  17. Characterization of methadone overdose: clinical considerations and the scientific evidence.

    PubMed

    Wolff, Kim

    2002-08-01

    Overdosing with methadone is a growing phenomenon in Britain and other countries due to the increase in prescription and the availability of this compound. Little is known of the circumstances surrounding methadone death due to some extent to the difficulty of defining drug-related death and also the difficulty of collecting clinical and biographical data in a predominantly illegal and marginal milieu. However, the evidence points to highest risk at night (to this end manifestations of its toxicity often go unrecognized) in those whose usual tolerance has been reduced and occurring some considerable time after ingestion. Further investigations are needed to elucidate fully the mechanism and spectrum of methadone overdose. Death from methadone is eminently preventable more so because of the long-term nature of the clinical sequelae. Indeed the key issue with methadone that sets it apart from other opioids is its potential for delayed toxicity. Consequently steps should be taken to disseminate the salient facts to all those who come into contact with the drug.

    This article examines the use of volunteers within hospital-based long-term care case management programs. As hospitals diversify into long-term care, the roles played by volunteers are also diversifying. A brief description of the involvement of volunteers with the frail elderly is followed by a comparison of the roles and relationships of volunteers within existing hospital auxiliaries and long-term care case management programs. Three models for structuring hospital-based volunteer programs that address the needs of the frail elderly within diverse communities are presented. Implications surrounding the involvement of volunteers beyond hospital walls are discussed.

    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

    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.

    2014-01-01

    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

    Background As a measure of quality, ambulatory surgery centers have begun reporting rates of hospital transfer at discharge. However, this may underestimate patient’s acute care needs after care. We conducted this study to determine rates and evaluate variation in hospital transfer and hospital-based, acute care within 7 days among patients discharged from ambulatory surgery centers. Methods Using data from the Healthcare Cost and Utilization Project, we identified adult patients who underwent a medical or surgical procedure between July 2008 and September 2009 at ambulatory surgery centers in California, Florida, and Nebraska. The primary outcomes were hospital transfer at the time of discharge and hospital-based, acute care (emergency department visits or hospital admissions) within 7-days expressed as the rate per 1,000 discharges. At the ambulatory surgery center level, rates were adjusted for age, sex, and procedure-mix. Results We studied 3,821,670 patients treated at 1,295 ambulatory surgery centers. At discharge, the hospital transfer rate was 1.1/1,000 discharges (95% CI, 1.1–1.1). Among patients discharged home, the hospital-based, acute care rate was 31.8/1,000 discharges (95% CI, 31.6–32.0). Across ambulatory surgery centers, there was little variation in adjusted hospital transfer rates (median=1.0/1,000 discharges [25th–75th percentile=1.0–2.0]), while substantial variation existed in adjusted hospital-based, acute care rates (28.0/1,000 [21.0–39.0]). Conclusions Among adult patients undergoing ambulatory surgery center care, hospital transfer at discharge is a rare event. In contrast, the hospital-based, acute care rate is nearly 30-fold higher, varies across centers, and may be a more meaningful measure for discriminating quality. PMID:24787100

    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

    In the last years the interest in monitoring drug exposure with human sweat as alternative biological fluid, is increasing. Sweat collection is convenient, less invasive and difficult to adulterate compared to traditional specimens. The objective of this study was to determine the excretion profile of methadone and other drugs into human sweat. Pharmscope sweat patches (Medical Europe Diagnostic, Madrid, Spain) were used on heroin abusers under methadone treatment. Sweat patches were applied to 10 heroin addicts and 3 drug free volunteers admitted into the study. Sweat patches were worn for about 1 week; urine, saliva and hair samples were collected at the time of the removal of patches. After the extraction, sweat eluates were directly analyzed by GC/MS for the presence of nicotine, cotinine, caffeine, methadone, EDDP and cocaine. The extracts were subsequently derivatized to detect benzoylecgonine, ecgonine methyl ester, morphine, codeine and 6-acetylmorphine. No false positive results were obtained on the drug free samples. All the patches showed positive results for methadone. Cocaine was detected in two cases. Mainly the parent drug was identified rather than the metabolites. The results obtained show the usefulness of sweat as complementary specimen to saliva and urine providing a longer detection window. Moreover, sweat testing offers the advantage of being a non-invasive means of obtaining information about drug exposure.

    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

    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.

    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

    Hospital-based physicians (HBPs) have been the recipients of considerable attention in health policy debates in recent years. This paper discusses issues and trends concerning HBPs and presents evidence on practice characteristics, compensation methods, and incomes of anesthesiologists, pathologists, and radiologists. Some comparisons with office-based MDs are included. The primary data source is composed of physician surveys sponsored by the Health Care Financing Administration and conducted by the National Opinion Research Center in 1977 and 1978. Findings generated from these surveys support past research showing that radiology is the most lucrative HBP specialty, followed by pathology and anesthesiology; hospital-based practice tends to be considerably more lucrative than office-based practice, taken as a whole. Survey findings are discussed in light of current policy developments in the health services sector. PMID:10309258

    The American population is aging, medical technology is advancing, and life expectancies are on the rise. At the same time hospitals are looking for additional sources of income due to the pressures of government regulations and managed care. One of the options for hospitals looking for additional sources of income is the hospital-based but free-standing comprehensive wellness and fitness center. Such centers go beyond the facilities, programs and services offered by traditional health and fitness centers. In addition to physical fitness programs, hospital-based wellness centers offer programs in CPR, nutrition, weight control and many other programs of interest to an aging but active American populace. This research documents the hospital industry, wellness industry and the prospects of success or failure for he hospital attempting such a venture. The focus of the research is the experience of a particular hospital with regard to the programs, facilities and services deemed most important by its target market. PMID:10163917

    Abstract Background and Objectives Breastfeeding, a public health priority, improves outcomes for infants. Methadone is dispensed as a racemic mixture; R-methadone is the active enantiomer. Pharmacologic data for R-methadone in breastmilk could improve risk–benefit decision-making for treatment of lactating women. This study estimated infant exposure to R- and S-methadone via breastmilk by theoretic infant dose (TID) and relative infant dose (RID) and reported the milk-to-maternal plasma (M/P) ratio. Methods Women treated with methadone doses of 40–200 mg/day (mean, 102 mg/day) provided concomitantly collected plasma and breastmilk samples 1–6 days after delivery. Most (16 of 20) samples were taken at the time of peak maternal plasma levels; thus infant exposure estimates are for maximum possible exposure. Concentrations of R- and S-methadone were measured in maternal plasma and breastmilk; M/P ratio, TID, and RID were calculated for each enantiomer and total methadone. Results The 20 participants were 18–38 years old and publicly insured; a quarter did not complete high school, and only one was not white. R-Methadone concentration was 1.3–3.0 times that of S-methadone in all breastmilk samples. The mean (SD) R-, S-, and total methadone M/P ratios were 0.52 (0.28), 0.28 (0.15), and 0.40 (0.21), respectively. Mean (range) R-, S-, and total methadone TID were 0.02 mg/kg/day (0.004–0.099), 0.013 mg/kg/day (0.002–0.071), and 0.033 mg/kg/day (0.006–0.170), respectively. Mean (range) RID of R-, S-, and total methadone were 2.7% (0.7–10.1%), 1.6% (0.3–7.2%), and 2.1% (0.52–8.8%), respectively. Conclusions R-Methadone is found in higher concentrations than S-methadone in breastmilk. Even at high methadone doses, breastmilk methadone concentrations were relatively low and support American Academy of Pediatrics recommendations that dose should not be a factor in determining whether women on methadone breastfeed.

    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.

    Over the past several years, Medical Examiners in Kentucky and around the nation have observed a dramatic rise in drug intoxication deaths involving the prescription medication methadone. This documented rise in methadone-related deaths requires a better understanding of methadone's pathophysiology and the ways it contributes to significantly increase morbidity and mortality. This study reviews 176 fatalities ascribed to methadone toxicity by the Office of the Chief Medical Examiner in Kentucky between 2000 and 2004. Postmortem toxicological analysis recorded a more than 10-fold increase in methadone toxicity fatalities, rising from 6 cases in 2000 to 68 cases in 2003. Of the 176 methadone-related fatalities, methadone was the only drug detected in postmortem blood and urine toxicological analyses in 11 (6.25%) cases. The mean methadone blood concentration of all 176 cases was 0.535 mg / L (0.02-4.0). The following psychoactive medications were detected: antidepressants (39.8%), benzodiazepines (32.4%), and other opioids in addition to methadone (27.8%). Cannabinoids were detected in 44 (28.4%) cases and cocaine or metabolite in 34 (21.9%) cases. Of the 95 cases with a known history of methadone use, 46 (48.4%) involved prescription by private physician. The interpretation of blood methadone concentrations alone or combined with other psychoactive drugs requires consideration of the subject's potential chronic use of and tolerance to the drug. A thorough investigation into the practices of procurement and use/abuse of methadone is essential to arrive at the proper designation of the cause of death.

    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

    Numerous studies have identified strategies to reduce mechanical ventilation duration by targeting appropriate sedation levels. However, applicability of these strategies to critically injured patients with burn injury has not been established. At our medical center, methadone is commonly used early in the care of burn patients to treat background pain and limit the development of opioid tolerance. The aim of this study is to evaluate the effect of early methadone initiation in critically injured burn patients requiring mechanical ventilation. This retrospective study compared patients who received early methadone with patients who did not while mechanically ventilated with the primary outcome of ventilator-free days in a 28-day period. Those who received methadone within 4 days of intubation and remained ventilated for 2 days after the first dose were included in the methadone group. Propensity scores were used to match up to three control patients to each methadone patient. Seventy patients (18 methadone and 52 matched control patients) were included in the final evaluation. Patients in the methadone group averaged 16.5 ventilator-free days compared with 11.5 in the control group (P = .03). There was no statistical difference in the duration of intensive care unit or hospital length of stay between groups. Our results suggest that early methadone initiation may have a significant effect on ventilator outcomes in critically injured patients with burn injury. However, further research is warranted.

    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.

    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.

    The purpose of this study was to compare the outcomes of a hospital-based home-care model with those of a conventional outpatient follow-up for mentally ill patients in Taiwan by means of cost-effectiveness analysis. The study design was a two group posthoc design. We interviewed 40 mentally ill patients who were followed up in the psychiatric outpatient department. Another 40 mentally ill patients who participated in a hospital based home care program were also interviewed. The outcome measures we used for interviews were disease maintenance behavior, psychotic symptoms, social function, service satisfaction, and cost. The cost for each patient was the sum of costs for all direct mental health services. The cost-effectiveness ratio showed that the costs of the hospital-based home care model (4.3) were lower than those of conventional outpatient follow-up (13.5) and that over a one-year period, the hospital-based home care model was associated with improvements in mental conditions, social functional outcomes, and service satisfaction. The improved outcomes and the lower costs in the hospital-based home care program support the view that it is the most cost-effective of the two. Policy makers may consider this analysis as they allocate resources and develop policy for the care of mentally ill patients.

    A Medical Information System must be current if it is to be a viable adjunct to patient care within a hospital setting. Hospital-based customization provides a means of achieving this timeliness with maximum user satisfaction. It, however, requires a major commitment in personnel time as well as additional software and training expenses. The enhanced control of system modifications and overall flexibility in planning the change process result in enthusiastic support of this approach by many hospitals. The key factors for success include careful selection of local personnel with adequate vendor support, extensive QA control, thorough auditing/validation and direct user involvement.

    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.

    This was a retrospective chart review to evaluate various risk factors associated with in-hospital mortality and intubation risk in acute methadone overdose. All patients admitted to an academic hospital in Tehran, Iran, during a 10-year period (2000-2009) constituted the study sample. Exclusion criteria were significant comorbidities and age under 18 years. Outcome variables were in-hospital mortality and being intubated during admission. A total of 802 patients were enrolled in the study. There were 15 (1.8%) deaths due to methadone overdose or its complications. The number of yearly admissions was 15 patients in 2000, 16 in 2001, 16 in 2002, 18 in 2003, 23 in 2004, 38 in 2005, 59 in 2006, 110 in 2007, 206 in 2008 and 301 in 2009. Based on logistic regression analysis, the most important independent variable predicting mortality was length of admission in toxicology ward [OR (95% CI): 1.6 (1.1-2.3)]. For the prediction of intubation, independent variables were Glasgow Coma Scale (GCS) score of 5-9 [OR (95% CI): 356.5 (9.8-12907.4)] in the emergency department (ED), miosis in the ED [356.9 (1.4-87872.5)] and respiratory rate in the ED [1.5 (1.1-2.1)]. Linear regression model for length of hospitalization showed patient age as the most important variable for prediction of this outcome. Despite a relatively low mortality rate, the increasing number of methadone-poisoned patients requires special attention to this common intoxication. Careful disposition of patients from ED to ordinary wards or intensive care units and also from higher to lower levels of care should be considered in methadone overdose. PMID:26301535

    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.

    Background In recent years there has been a sharp increase in the use of illicit methadone as well as methadone-related overdose deaths. Objective The purpose of this study is to describe factors associated low- and high-frequency methadone use in a cohort of rural Appalachian drug users. Methods Interviews assessing sociodemographics, illicit drug use and drug treatment, psychiatric disorders, health, and sociometric drug network characteristics were conducted with 503 rural drug users between 2008 and 2010. A two-level mixed effects regression model was utilized to differentiate low- (one use per month or less in the past 6 months) versus high-frequency (daily or weekly use in the past 6 months) illicit methadone users. Results The lifetime prevalence of illicit methadone use in this population was 94.7% (n=476) and slightly less than half (46.3%) were high-frequency users. In the mixed effects regression model, initiating illicit methadone use at a younger age was associated with high-frequency illicit methadone use. Whereas taking a prescribed medication for a physical problem, undergoing additional weeks of outpatient drug free treatment, daily OxyContin® use in the past month, and having fewer ties and second order connections in the drug network reduced the odds of high-frequency illicit methadone use. Conclusions Rates of illicit methadone use and high-frequency illicit methadone use among this sample of rural drug users were considerably higher than those previously reported in the literature. Health practitioners in rural areas should routinely screen for illicit opioid use, including methadone. PMID:23841864

  11. Recent developments in maintenance prescribing and monitoring in the United Kingdom.

    After a brief historical review of British drug legislation and public and governmental attitudes, this paper describes the wide range of policies and practices that have appeared since the explosion of illicit drug abuse in the 1960s. The spectrum goes from a reluctance to prescribe at all to maintenance on injectable opiates. Comparisons are made with differing attitudes to the availability of abortion in public health services. Compared with 5 years ago, about three times more methadone is being prescribed. There is a steady increase in prescriptions for injectable methadone but heroin maintenance is still rare. The "British System" permits great flexibility in the choice of opiates for maintenance. Some amphetamine-prescribing programmes also exist. Hair analysis for drugs to monitor levels of both prescribed and unprescribed drugs is a welcome and promising alternative to undignified and often misleading urine tests. PMID:10101376

    Aim: To assess the usefulness of cord and serum methadone concentrations at 2 days of age in predicting the severity of neonatal abstinence syndrome (NAS) in infants whose mothers received methadone during pregnancy. Methods: After informed consent, infants were enrolled if they were delivered at 35 weeks gestation or greater. Relevant information was collected from maternal notes. A sample of cord blood was taken at delivery, with a follow up sample at 48 hours of age. The samples were analysed in batches, and the results were unavailable to the attending clinical staff. Infants were treated for NAS on clinical grounds according to a standardised scoring system. Results: Twenty five of 36 eligible infants over the 21 month period of the study were enrolled. Of these, 12 required treatment for NAS. Maternal methadone dose did not predict the need for treatment. However, infants who required treatment had significantly lower methadone concentrations in cord blood than the group who did not receive treatment (31 v 88 ng/ml respectively; p  =  0.029). Paired blood samples for methadone concentrations were available for 17 infants. All but one of the 12 infants who required treatment had undetectable concentrations of methadone in the postnatal sample, whereas the median postnatal methadone concentration in untreated infants was 23 ng/ml (p  =  0.002). Conclusions: Methadone concentrations taken from cord blood may identify infants at greater risk of neonatal withdrawal and therefore requiring treatment. PMID:15321955

  13. The glycosylation of AGP and its associations with the binding to methadone.

    Methadone remains the most common form of pharmacological therapy for opioid dependence; however, there is a lack of explanation for the reports of its relatively low success rate in achieving complete abstinence. One hypothesis is that in vivo binding of methadone to the plasma glycoprotein alpha-1-acid glycoprotein (AGP), to a degree dependent on the molecular structure, may render the drug inactive. This study sought to determine whether alterations present in the glycosylation pattern of AGP in patients undergoing various stages of methadone therapy (titration < two weeks, harm reduction < one year, long-term > one and a half years) could affect the affinity of the glycoprotein to bind methadone. The composition of AGP glycosylation was determined using high pH anion exchange chromatography (HPAEC) and intrinsic fluorescence analysed to determine the extent of binding to methadone. The monosaccharides galactose and N-acetyl-glucosamine were elevated in all methadone treatment groups indicating alterations in AGP glycosylation. AGP from all patients receiving methadone therapy exhibited a greater degree of binding than the normal population. This suggests that analysing the glycosylation of AGP in patients receiving methadone may aid in determining whether the therapy is likely to be effective.

  15. Methadone as an analgesic: a review of the risks and benefits.

    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.

    2016-02-01

    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.

    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

  20. Maintenance Medication for Opiate Addiction: The Foundation of Recovery

    PubMed Central

    Bart, Gavin

    2012-01-01

    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 HIV, 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 FDA for long-term treatment of opiate dependence: the opioid agonist methadone, the opioid partial 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. While no direct comparisons between extended release naltrexone injections and either methadone or buprenorphine exist, indirect comparison of retention shows inferior outcome compared to methadone and buprenorphine. Further work is needed to compare directly 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

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

    PubMed Central

    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.

    The psychiatric care of opioid users receiving agonist therapies is often complicated by high rates of illicit drug use (Brooner et al., 2013). The present study evaluates if illicit drug use (i.e., opioids, cocaine, sedatives) detected at the start of psychiatric care affects treatment response. Methadone maintenance patients (n = 125) with at least one current psychiatric disorder completed a 3-month randomized clinical trial evaluating the efficacy of financial incentives on attendance to on-site integrated substance abuse and psychiatric services (Kidorf et al., 2013). The present study re-analyzes the data set by grouping participants into one of two conditions based on the 4-week baseline observation: (1) no illicit drug use (baseline negative; n = 50), or (2) any illicit drug use (baseline positive; n = 75). All participants received a similar schedule of psychiatric services, and had good access to prescribed psychiatric medications. The Global Severity Index (GSI) of the Hopkins Symptom Checklist-Revised was administered monthly to evaluate changes in psychiatric distress. Results showed that while both conditions evidenced similar utilization of on-site psychiatric services, baseline negative participants remained in treatment somewhat longer (80.7 vs. 74.8 days, p = .04) and demonstrated greater reductions in GSI scores than baseline positive participants at month 3 (p = .004). These results have implications for interpreting previous studies that have shown inconsistent efficacy of pharmacotherapy and other psychiatric treatments, and for providing clinical care for patients with co-occurring substance use and psychiatric disorders.

    While higher levels of dispositional optimism are associated with decreased levels of psychopathology and pain, and higher levels of mental health functioning—important outcomes in opioid treatment programs—a paucity of studies has examined dispositional optimism among individuals with opioid use disorders. The aim of this study was to examine the clinical correlates (i.e., psychopathology, pain status) of dispositional optimism in opioid dependent patients enrolled in methadone maintenance treatment (MMT). A survey targeting demographics, pain, psychopathology, and dispositional optimism was administered to 150 MMT patients. In multivariable analyses, higher levels of dispositional optimism were significantly associated with lower levels of depression, screened personality disorder criteria, screened symptoms of PTSD, and pain-related emotional strain. In comparison to those without a history of chronic pain (i.e., non-cancer related physical pain lasting at least 3 months), MMT patients who reported either lifetime or current chronic pain exhibited significantly lower levels of dispositional optimism. The associations among higher levels of dispositional optimism, lower levels of psychopathology, and lower pain-related emotional strain suggest that research focusing on the efficacy of specific interventions to promote dispositional optimism in MMT patients is warranted.

    This study is an observational cross-sectional study aimed to examine the possible demographic and social characteristics of patients enrolled at the Methadone Maintenance Therapy Adherence Clinic (MMTAC) in Malaysia. Medical records from year 2009 - 2011 were Reviewed. Demographic, social characteristics and laboratory examinations such as age, gender, race, clinic attendances and urine analysis were recorded. Subjects were selected by means of convenient sampling but based on the specified inclusion and exclusion criteria. Data were analyzed by either Chi-square test, Fisher's exact test Mann-Whitney U-test, with the limit of significance was set at p < 0.05. Demographically, this study found that the ratio of Malays, Chinese and Indian enrolled to the MMTAC program is similar to the distribution of races in Malaysia. Their starting age for drug use was between 14-35 years and the age to enrolment between 30-58 years. Socially, many are unemployed, lowly educated and married. Most are drug users with a high percentage of HCV accompanied with impaired liver function. Retention rate was 87% but illicit drug use was at 57.50%. However, percentage of employment increased significantly after therapy. The study managed to identify several demographical and social distributions of patients attending the MMTAC. Although attendance rate was high, many were on illicit drug use. Nevertheless, employment rate improved significantly.

    This clinical trial evaluated a contingency management intervention designed to improve medication adherence among HIV-positive methadone maintenance patients. After a 4-week baseline observation phase, eligible participants (N=66) were randomly assigned to: (a) medication coaching sessions every other week to assist with adherence strategies (comparison group) or (b) medication coaching plus voucher reinforcement for opening electronic medication caps on time (voucher group). Baseline adherence (percent doses taken/percent total possible doses) was 51% using electronic measurement, 75% using self-report and 75% using pill count. The intervention was provided for 12 weeks, with a 4-week follow-up. The primary outcome results of the clinical trial indicated effectiveness during the intervention, with significant mean adherence differences between voucher and comparison groups using electronic measurement (78% versus 56%), pill count (86% versus 75%), and self-report (87% versus 69%). Differences between groups faded after vouchers were discontinued. Contingency management shows promise as a strategy to promote antiretroviral medication adherence in this population.

  7. Methadone Reverses Analgesic Tolerance Induced by Morphine Pretreatment

    PubMed Central

    Posa, Luca; Accarie, Alison; Marie, Nicolas

    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

    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.

    Buprenorphine and methadone are opioid-receptor agonists used as opioid substitution therapy during pregnancy to limit exposure of the fetus to cycles of opioid withdrawal and reduce the risk of infectious comorbidities of illicit opioid use. As part of a comprehensive care plan, such therapy may result in improved access to prenatal care, reduced illicit drug use, reduced exposure to infections associated with intravenous drug use, and improved maternal nutrition and infant birth weight. This article describes differences in patient selection between the two drugs, their relative safety during pregnancy, and changes in daily doses as a guide for prescribing clinicians.

  10. A Retrospective Evaluation of Inpatient Transfer from High-Dose Methadone to Buprenorphine Substitution Therapy.

    PubMed

    2015-10-01

    The product license of buprenorphine/naloxone for opioid substitution therapy indicates reducing methadone concentrations to 30 mg or less per day for a minimum of 1 week before transferring patients to buprenorphine and no sooner than 24 hours after the last methadone dose, because of the risk of precipitated withdrawal and a corresponding high risk of relapse to opioid use. There are few studies describing high-dose methadone transfers. This retrospective case review assessed the feasibility of transferring patients on methadone doses above 30 mg/day to buprenorphine or buprenorphine/naloxone in the inpatient setting. Six of seven patients on 60-120 mg/day of methadone successfully completed the transfer, and four cases tested negative for opiates at long-term follow-up (6-15 months). This suggests that methadone transfer to buprenorphine can be performed rapidly without the need to taper methadone doses in patients indicated for a therapeutic switch. This small study is hypothesis-generating; larger, well-designed trials are needed to define a protocol that can be used routinely to improve and widen transfers to buprenorphine when indicated.

    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.

    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.

    Increasing rates of maternal opioid use during pregnancy and neonatal withdrawal, termed neonatal abstinence syndrome (NAS), are public health concerns. Prenatal buprenorphine maintenance treatment (BMT) versus methadone maintenance treatment (MMT) may improve neonatal outcomes, but associations vary. To summarize evidence, we used a random-effects meta-analysis model and estimated summary measures of BMT versus MMT on several outcomes. Sensitivity analyses evaluated confounding, publication bias, and heterogeneity. Subjects were 515 neonates whose mothers received BMT and 855 neonates whose mothers received MMT and who were born from 1996 to 2012 and who were included in 12 studies. The unadjusted NAS treatment risk was lower (risk ratio=0.90, 95% confidence interval (CI): 0.81, 0.98) and mean length of hospital stay shorter (-7.23 days, 95% CI: -10.64, -3.83) in BMT-exposed versus MMT-exposed neonates. In treated neonates, NAS treatment duration was shorter (-8.46 days, 95% CI: -14.48, -2.44) and morphine dose lower (-3.60 mg, 95% CI: -7.26, 0.07) in those exposed to BMT. BMT-exposed neonates had higher mean gestational age and greater weight, length, and head circumference at birth. Fewer women treated with BMT used illicit opioids near delivery (risk ratio=0.44, 95% CI: 0.28, 0.70). Simulations suggested that confounding by indication could account for some of the observed differences. Prenatal BMT versus MMT may improve neonatal outcomes, but bias may contribute to this protective association. Further evidence is needed to guide treatment choices.

    Background: It is well known that contact with some physical, chemical or biological compounds can increase the incidence of mutation. Among these compounds, are pharmaceuticals that meet long duration of use and potentially could be misused and taken more than the ordered dosage. Objectives: The aim of this study was to evaluate mutagenic effect of methadone in addicted patients referred to Imam Khomeini Hospital in Ahvaz by single cell gel electrophoresis technic or comet assay. Patients and Methods: In this study, 90 subjects were divided into dichromate treated group, no treated healthy volunteers group and test group. Each group included 30 subjects. Screening was performed according to questionnaire and qualified subjects were entered the study. Blood samples were collected and lymphocytes were isolated, mixed with low melting point agarose for slide preparation according to standard method. Slides were analyzed using fluorescence microscope and comet patterns were assessed. Results: The mutagenicity index in addicted group was robustly higher than healthy volunteers. Fortunately, this significant difference was lower than positive control. Conclusions: Genome instability in addicted patients was demonstrated in this study. Controversially, considering incoherent results of previous studies and our data, more studies in longer duration of methadone use are needed to elucidate the consequence. PMID:25866713

    Voltage-dependent ionic currents were recorded from squid giant fiber lobe neurons using the whole-cell patch-clamp technique. When applied to the bathing solution, methadone was found to block IK, I Na and I Ca. Both I Na and I Ca were reduced without apparent change in kinetics and exhibited IC(50)'s of 50-100 and 250-500 mu M, respectively, at +10 mV. In contrast, IK was reduced in a time-dependent manner that is well fit by a simple model of open channel block (K(D)= 32+/- or 2 mu M, +60 mV, 10 degrees Celsius). The mechanism of I(K) block was examined in detail and involves a direct action of methadone, a tertiary amine, on K channels rather than an opioid receptor-mediated pathway. The kinetics of I(K) block resemble those reported for internally applied long chain quaternary ammonium (QA) compounds; and recovery from I(K) block is QA-like in its slow time course and strong dependence on holding potential. A quaternary derivative of methadone (N-methyl-methadone) only reproduced the effects of methadone on I(K) when included in the pipette solution; this compound was without effect when applied externally. I(K) block thus appears to involve diffusion of methadone into the cytoplasm and occlusion of the open K channel at the internal QA blocking site by the protonated form of the drug. This proposed mode of action is supported by the pH and voltage dependence of block as well as by the observation that high external K+ speeds the rate of drug dissociation. In addition, the effect of methadone on I(K) evoked during prolonged (300 ms) depolarizations suggests that methadone block may interfere with endogenous K+ channel inactivation. The effects of temperature, methadone stereoisomers, and the methadone-like drugs propoxyphene and nor-propoxyphene on IK block were examined. Methadone was also found to block I(K) in GH3 cells and in chick myoblasts.

    Chronic hepatitis C virus (HCV) infection is highly prevalent among current and former drug users. However, the minority of patients enrolled in drug treatment programs have initiated HCV treatment. New models are needed to overcome barriers to care. In this retrospective study, we describe the implementation and outcomes of 42 patients treated in a Concurrent Group Treatment (CGT) program. Patients participated in weekly provider-led group treatment sessions which included review of side effects; discussion of adherence and side effect management; administration of interferon injections; brief physical exam; and ended with brief meditation. Of the first 27 patients who initiated CGT, 42% achieved a sustained viral response. Additionally, 87% (13/15) of genotype-1 infected patients treated with direct acting antiviral agent achieved an undetectable viral load at 24 weeks. The CGT model may be effective in overcoming barriers to treatment and improving adherence and outcomes among patients enrolled in drug treatment programs. PMID:23036920

    Background Drug users (DUs) are at high risk of viral hepatitis A, B, and C (HAV, HBV, HCV). Methods We examined the prevalence of HAV, HBV, and HCV, associated factors, and vaccine seroconversion among drug treatment program participants in a randomized controlled trial of hepatitis care coordination. Results Of 489 participants, 44% and 47% required HAV/HBV vaccination, respectively; 59% were HCV positive requiring linkage to care. Factors associated with serologic statuses, and vaccine seroconversion are reported; implications for strategies in drug treatment settings are discussed. Conclusions Results suggest generalizable strategies for drug treatment programs to expand viral hepatitis screening, prevention, vaccination and linkage to care. PMID:25299236

    Drug--including opioid--dependence is common in correctional populations, however little research exists on interventions for women offenders. Based on retrospective administrative data, we examined rates of return to custody (RTC) among three samples of Canadian federal women offenders with problematic opioid use (total n=137): (1) a group initiated on MMT during incarceration who continued MMT post-release (MMT-C; n=25); (2) a group initiated on MMT but who terminated treatment post-release (MMT-T; n=67), and (3) a non-MMT control group (MMT-N; n=45). Study groups were similar regarding socio-demographic, drug use and criminogenic indicators. Based on an unadjusted Cox proportional hazards model, the MMT-C group had a 65% lower risk of RTC than the MMT-N (reference) group (HR 0.35, CI 0.13-0.90); RTC risk was not different between the MMT-T and the reference group. Most RTCs were for technical revocations (e.g. violation of a legal condition of their release). Continuous MMT following release from corrections appears to be effective in reducing recidivism in women offenders with opioid problems; barriers to MMT in the study population should be better understood and ameliorated.

    Contexte : Treize centres de traitement par méthadone (MMT) dans le Yunnan, la province la plus touchée par le virus de l'immunodéficience humaine (VIH) en Chine.Objectifs : Déterminer, parmi les participants VIH négatifs, la proportion de perdus de vue (ceux qui ont manqué l'examen de suivi à 6 mois), les facteurs associés à cet abandon du suivi, le taux de séroconversion VIH et les facteurs associés.Schéma : Etude prospective de cohorte d'octobre 2008 à avril 2011. Tous les participants ont rempli un questionnaire structuré prétesté afin d'identifier ces facteurs et on leur a proposé un test VIH tous les 6 mois. L'analyse des données a été réalisée à l'aide du test χ(2) et de la régression logarithmique binomiale.Résultats : Sur 1146 patients, 541 (47%) ont été perdus de vue en 2 ans et demi. Les facteurs associé à cet abandon comprenaient : <6 mois de séjour préalable dans un centre MMT, localisation peu pratique du centre et dose moyenne de méthadone ⩽60 mg/jour avec un risque relatif (RR) ajusté de 1,4 (IC95% 1,2–1,5), 1,2 (IC95% 1,0–1,4) et 1,1 (IC95% 1,0–1,3), respectivement. Le taux global de séroconversion était de 6,6% personnes-années (IC95% 3,7–11). Le fait de ne pas vivre avec un partenaire contribuait à un taux plus élevé de VIH avec un RR ajusté de 3,6 (IC95% 1,0–12,8).Conclusion : Le taux de rétention des participants à un traitement en centre MMT au Yunnan n'était pas satisfaisant. Une prestation de services décentralisée au niveau communautaire avec observation directe du traitement serait plus pratique et pourrait améliorer cette rétention.

    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

    This study compared urinary 5-hydroxytryptophol (5HTOL) with breath-ethanol testing as objective ways to disclose recent drinking by outpatients attending a methadone maintenance treatment clinic. Information about quantity and frequency of alcohol use was obtained by confidential self-reports. Random screening was performed on Mondays-Fridays in connection with routine clinic visits for methadone dosing. An observed urine sample for monitoring of illicit drug use and determination of 5HTOL, expressed as a ratio to 5-hydroxyindole-3-acetic acid (5HIAA), was obtained from 202 patients (59 women and 143 men), 16 of whom refused to complete the self-report and/or do a breath-ethanol test. Patients taking disulfiram or calcium carbimide for alcohol detoxification were excluded. Among the 177 subjects remaining, 47 (26.6%) reported intake of any alcohol on the previous day (range, 10-230 g ethanol; median, 40). Only four of those could be identified by a positive breath-test, while 17 showed a urinary 5HTOL/5HIAA ratio above the cutoff limit. Their alcohol consumption (median, 60 g) was significantly higher compared with those showing ratios within the reference interval (median, 35 g). The sensitivity of 5HTOL/5HIAA testing for detecting self-reported drinking in excess of 50 g ethanol was 77%. An additional nine patients who claimed abstinence still showed abnormal 5HTOL/5HIAA ratios, and so did three of the patients who refused to do a breath-ethanol test and/or complete the self-report. Altogether, 59 of 190 methadone-maintained patients (31.1%) had been drinking any alcohol on the previous day (i.e. Sunday-Thursday) according to self-report and/or urinalysis data, 29 (49.2%) of whom were identified by the urinary 5HTOL/5HIAA ratio and only four (6.8%) by utilizing breathalyzer.

    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

    Chronic treatment of pain with opiate drugs can lead to analgesic tolerance and drug dependence. Although all opiate drugs can promote tolerance and dependence in practice, the severity of those unwanted side effects differs depending on the drug used. Although each opiate drug has its own unique set of pharmacological profiles, methadone is the only clinically used opioid drug that produces substantial receptor endocytosis at analgesic doses. Here, we examined whether moderate doses of methadone carry any benefits over chronic use of equianalgesic morphine, the prototypical opioid. Our data show that chronic administration of methadone produces significantly less analgesic tolerance than morphine. Furthermore, we found significantly reduced precipitated withdrawal symptoms after chronic methadone treatment than after chronic morphine treatment. Finally, using a novel animal model with a degrading μ-opioid receptor we showed that, although endocytosis seems to protect against tolerance development, endocytosis followed by receptor degradation produces a rapid onset of analgesic tolerance to methadone. Together, these data indicated that opioid drugs that promote receptor endocytosis and recycling, such as methadone, may be a better choice for chronic pain treatment than morphine and its derivatives that do not.

    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.

    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

    Several researchers have examined the personality of chemical abusers by employing a multivariate clustering strategy. All of these studies focused on hospitalized inpatient addicts. Only one included females in the study. The purpose of this study is to examine the transposed data factor analytically derived profiles of female methadone maintained outpatients. All clients were given the Mini-Mult short form version of the Minnesota Multiphasic Personality Inventory. Seventy profiles were randomly selected from 130 female profiles. Program Factor of the Analyses of Behavioral Sciences Data program series was employed in statistically processing this data. Descriptions of the five factors are provided. Most of the profile types seem to fall into the normal or personality disordered categories. Forth-two percent of the profiles were normal, 24% were Personality Disorders, 6% were Neurotic, and 28% were unclassified using five factors.

  19. Pharmacological maintenance treatments of opiate addiction.

    PubMed

    Bell, James

    2014-02-01

    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.

    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.

    2012-01-01

    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

  2. Patient and clinician's ratings of improvement in methadone-maintained patients: Differing perspectives?

    PubMed Central

    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.

    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.

    Morphine and methadone share the property of μ-opioid receptor agonism yet have markedly different cardiovascular actions suggesting additional properties are at play. We investigated the i.v. dose-response relationships of the opioids on cardiovascular metameters in anaesthetised rats in the absence or presence of H1- and H2-receptor antagonism and the μ-opioid antagonist naloxone. In vitro tissue assays were employed to define more clearly cardiac and vascular mechanisms of action. Morphine (9, 30, 90mg/kg i.v.) decreased heart rate (HR) and mean arterial pressure (MAP) - responses that were blocked by naloxone pretreatment (10mg/kg i.v.). In contrast, methadone (3, 10, 30mg/kg i.v.) caused dramatic short-lived (1-3min) bradycardia, hypotension and lengthening of the QT interval before stabilising 5min after i.v. dosing. Only the steady-state responses of HR and MAP were blocked by naloxone. Mepyramine (10mg/kg i.v.) and cimetidine (100mg/kg i.v.) also blocked the naloxone-sensitive components. In isolated small mesenteric arteries precontracted by K(+) 62mM or endothelin-1, methadone (1-30μM) relaxed vessels while morphine (1-100μM) had no effect. Pretreatment with naloxone (10μM), indomethacin (30μM) or nitro-l-arginine (100μM) did not affect the relaxation to methadone. In rat isolated left atria, morphine and methadone inhibited inotropic responses at high concentrations (100μM). In rat papillary muscle and right atria, methadone was more than 30 times more potent at lengthening the refractory period and slowing the atrial rate than morphine. We conclude that methadone is a potent vasodilator agent, possibly through blocking L-type calcium channels.

    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.

    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

    1. In microsomes prepared from three human livers, methadone competitively inhibited the O-demethylation of dextromethorphan, a marker substrate for CYP2D6. The apparent Ki value of methadone ranged from 2.5 to 5 microM. 2. Two hundred and fifty-two (252) white Caucasians, including 210 unrelated healthy volunteers and 42 opiate abusers undergoing treatment with methadone were phenotyped using dextromethorphan as the marker drug. Although the frequency of poor metabolizers was similar in both groups, the extensive metabolizers among the opiate abusers tended to have higher O-demethylation metabolic ratios and to excrete less of the dose as dextromethorphan metabolites than control extensive metabolizer subjects. These data suggest inhibition of CYP2D6 by methadone in vivo as well. 3. Because methadone is widely used in the treatment of opiate abuse, inhibition of CYP2D6 activity in these patients might contribute to exaggerated response or unexpected toxicity from drugs that are substrates of this enzyme.

    Prolongation of the QT interval associated with ventricular arrhythmias has been the most common cause of the restriction or withdrawal of drugs from the market in the past 10 years. Methadone, a synthetic opioid that is increasingly used for the management of chronic pain, has recently been implicated in the development of the prolonged QT syndrome. We present a case report of a patient who developed a prolonged QT while being treated with oral methadone for a chronic pain syndrome. Of particular interest in this patient is the fluctuation of the QT interval at a stable dose of methadone, suggesting that a single normal electrocardiogram (ECG) does not guarantee that the patient is not at risk of ventricular arrhythmias. After reviewing the current literature, we suggest that there is no dose of methadone that may be considered to be completely safe. Other risk factors for prolonged QT interval such as underlying cardiac abnormalities, electrolyte disturbances, and concurrent medications should be sought, and all patients should be monitored with serial ECGs even when methadone doses remain stable.

    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

    While opioid dependence has more treatment agents available than other abused drugs, none are curative. They can, however, markedly diminish withdrawal symptoms and craving, and block opioid effects due to lapses. The most effective withdrawal method is substituting and tapering methadone or buprenorphine, α-2 Adrenergic agents can ameliorate untreated symptoms or substitute for agonists if not available. Shortening withdrawal by precipitating it with narcotic antagonists has been studied, but the methods are plagued by safety issues or persisting symptoms. Neither the withdrawal agents nor the methods are associated with better long-term outcome, which appears mostly related to post-detoxification treatment. Excluding those with short-term habits, the best outcome occurs with long-term maintenance on methadone or buprenorphine accompanied by appropriate psychosocial interventions. Those with strong external motivation may do well on the antagonist naltrexone. Currently, optimum duration of maintenance on either is unclear. Better agents are needed to impact the brain changes related to addiction. PMID:18286804

    Research demonstrates that injection drug users with HIV and/or AIDS have difficulty adhering to complex regimens of HIV medications. Because of the risk of increased viral resistance associated with irregular medication adherence, there is considerable clinical need to assist clients who abuse substances in taking their antiretroviral medications on time and as directed. This article outlines intervention strategies to improve medication adherence among clients who are in methadone maintenance. In this treatment manual, the authors delineate contingency management procedures, including voucher incentives and a fishbowl lottery prize system. They also describe intervention elements and adherence tools for medication coaching. The purpose of this manual is to describe the intervention procedures for clinicians and to serve as a resource for drug abuse treatment programs that serve clients who are HIV-positive.

    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

    Abuse of prescription opioids is a growing problem. The number of methadone pain pills distributed now exceeds liquid methadone used in opioid treatment, and the increases in buprenorphine indicators provide evidence of the need to monitor and intervene to decrease the abuse of this drug. The need for additional and improved data to track trends is discussed, along with findings as to the characteristics of the users and combinations of drugs. Data on toxicities related to methadone or buprenorphine, particularly in combination with other prescribed drugs, are presented and clinical implications and considerations are offered. These findings underscore the need for physicians to be aware of potential toxicities and to educate their patients regarding these issues. PMID:20132124

    This article provides an overview and discussion of the collective maternal, fetal and neonatal outcome research on women maintained on methadone or buprenorphine during pregnancy. Its focus is on an assessment of the comparative effectiveness of methadone and buprenorphine pharmacotherapy, with particular attention given to recent findings from the literature. Recommendations for clinical practice are outlined, and directions for future research are presented. Findings from comparative studies of methadone and buprenorphine underscore the efficacy of both medications in preventing relapse to illicit opioid use in the treatment of opioid-dependent pregnant patients, as well as the simplicity of induction onto methadone and patient retention while receiving such therapy. Fetal monitoring suggests that buprenorphine results in less fetal cardiac and movement suppression than does methadone. The clinical implications of these findings need future exploration. For the neonate, evidence from studies using a wide range of designs, including retrospective chart reviews, prospective observational studies, and randomized clinical trials, show consistent results, with prenatal exposure to buprenorphine resulting in less severe neonatal abstinence syndrome relative to methadone. Any medication given to pregnant women should be prescribed only after considering the risk : benefit ratio for the maternal-fetal dyad. Medication choices for each opioid-dependent patient during pregnancy need to be made on a patient-by-patient basis, taking into consideration the patient's opioid dependence history, previous and current treatment experiences, medical circumstances and treatment preferences. Moreover, for a full remission of opioid addiction to be sustainable, both post-partum and across the lifespan, treatment providers must not rely solely on medication to treat their patients but should also utilize women-specific comprehensive treatment models that address the underlying

    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.

    The development and approval of levo-alpha-acetylmethadol (LAAM) as a pharmacotherapeutic agent in opioid agonist therapy provided an alternative to methadone. Clinicians recognized the potential benefits that LAAM, a synthetic mu agonist with pharmacological properties which differ from those of methadone,could have in the treatment management of addicts in opioid agonist therapy. We report our experience utilizing LAAM from 1995 to 1999 at the Hines VA opioid agonist therapy clinic. The addition of LAAM to the clinic's treatment armamentarium has resulted in management options that have improved the areas of patient recruitment, patient retention, patient traffic, take-home medication, detoxification, and treatment outcomes.

  19. Illicit use of methadone and buprenorphine among adolescents and young adults in Sweden

    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

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.

    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.

    It's been the trend for some years that, with their own particular set of challenges and constraints, hospital-based home health agencies have struggled to maintain profitability and efficiency in their operations. That can especially be true for hospital-based agencies operating in more rural areas, even as such agencies have been shown to play an important--or even critical--role in ensuring individuals in the communities they serve have access to needed treatment and health care services. Two executives who've successfully led a rural hospital-based agency discuss how to engage employees, referral sources, and communities and instill the right core philosophy to help your business succeed and grow.

    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.

    This review article summarizes the results of all available clinical trials considering the use of slow-release oral morphine (SROM) for opioid maintenance treatment (OMT). All studies published up to October 2010 and assessing SROM for OMT in adult patients are included. Three independent reviewers assessed the selected articles using a standardized checklist. Study design, study length and number of subjects included were recorded. Data about retention rate (proportion of participants remaining under maintenance treatment at the end of the study), quality of life, withdrawal symptoms, craving, additional drug consumption, driving capacity and adverse events were collected. We identified 13 articles corresponding to nine clinical trials considering the use of SROM for OMT. Among them, only one was a randomized trial and one was a controlled not randomized trial. All other studies were uncontrolled. Retention rates were good (from 80.6 to 95%) with SROM maintenance, but similar retention rates were obtained with methadone. Most of the studies showed that quality of life, withdrawal symptoms, craving and additional drug consumption improved with SROM. However, there was no comparison with other maintenance drugs. As most of the studies assessing SROM efficacy were uncontrolled, there is no definite evidence that SROM is an effective alternative to methadone for OMT. PMID:21265874

    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

    Objective Methadone coverage is poor in many countries due in part to methadone induction being possible only in specialized care (SC). This multicenter pragmatic trial compared the effectiveness of methadone treatment between two induction models: primary care (PC) and SC. Methods In this study, registered at ClinicalTrials.Gov (NCT00657397), opioid-dependent individuals not on methadone treatment for at least one month or receiving buprenorphine but needing to switch were randomly assigned to start methadone in PC (N = 155) or in SC (N = 66) in 10 sites in France. Visits were scheduled at months M0, M3, M6 and M12. The primary outcome was self-reported abstinence from street-opioids at 12 months (M12) (with an underlying 15% non-inferiority hypothesis for PC). Secondary outcomes were abstinence during follow-up, engagement in treatment (i.e. completing the induction period), retention and satisfaction with the explanations provided by the physician. Primary analysis used intention to treat (ITT). Mixed models and the log-rank test were used to assess the arm effect (PC vs. SC) on the course of abstinence and retention, respectively. Results In the ITT analysis (n = 155 in PC, 66 in SC), which compared the proportions of street-opioid abstinent participants, 85/155 (55%) and 22/66 (33%) of the participants were classified as street-opioid abstinent at M12 in PC and SC, respectively. This ITT analysis showed the non-inferiority of PC (21.5 [7.7; 35.3]). Engagement in treatment and satisfaction with the explanations provided by the physician were significantly higher in PC than SC. Retention in methadone and abstinence during follow-up were comparable in both arms (p = 0.47, p = 0.39, respectively). Conclusions Under appropriate conditions, methadone induction in primary care is feasible and acceptable to both physicians and patients. It is as effective as induction in specialized care in reducing street-opioid use and ensuring engagement and

    2008-01-01

    Background The prevalence of smoking is very high among methadone users. As a method of delivering health education, computers can be utilized effectively. However computer-assisted education in methadone users has not been evaluated systematically. Objective This study was aimed at assessing feasibility and patient acceptance of an interactive educational module of a multi-component smoking cessation counseling computer program for former illicit drug users treated in an outpatient methadone clinic. Methods The computer-mediated education for hazards of smoking utilized in this study was driven by major constructs of adult learning theories. The program interface was tailored to individuals with minimal computer experience and was implemented on a touch screen tablet PC. The number of consecutive methadone-treated current smokers enrolled in the study was 35. After providing socio-demographic and smoking profiles, the patients were asked to use the educational program for 40 minutes. The impact of the computer-mediated education was assessed by administering a pre- and post-intervention Hazards of Smoking Knowledge Survey (HSKS). An attitudinal survey and semi-structured qualitative interview were used after the educational session to assess the opinions of participants about their educational experience. Results The computer-mediated education resulted in significant increase of HSKS scores from 60.5 ± 16.3 to 70.4 ± 11.7 with t value 3.69 and P < .001. The majority of the patients (78.8%) felt the tablet PC was easy to use, and most of the patients (91.4%) rated the educational experience as good or excellent. After controlling for patient baseline characteristics, the effect of computer-mediated education remained statistically significant. Conclusions Computer-assisted education using tablet PCs was feasible, well-accepted, and an effective means of providing hazards of smoking education among methadone users. PMID:18984556

    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: To assess patients' satisfaction and to evaluate methadone therapy program, it is important to understand the experiences of opium dependents during the treatment period in methadone centers and determine the quality of this program and revise standards based on that. This study aimed to describe the nature and structure of patients' experiences during treatment in methadone centers. Methods: This was a qualitative method using phenomenology. Sampling was purposive and the participants were selected from opium dependents referred to Kerman methadone centers during 2007. Sampling continued until data saturation and the sample size was 32. Colaizzi's method was applied for data analysis. Findings: The findings of this study included 27 codes categorized in four main groups: experiences of structure, personnel, patients, and regulations. These four categories showed the main structure of experiences in methadone centers. Conclusion: Lack of treatment centers in near-by cities or the problems of those centers suggest that it is necessary to establish new centers or solve the problems of centers in near-by cities. The type of patients referring to the centers plays a role in treatment process. The regular presence of physicians and other personnel and their concerns and care for patients as well as longer working hours of the centers have roles in patients' satisfaction and increase of consistency with treatment. Discussing the rules and regulations of the center with patients including the obligatory of daily reference to the center to obtain medicine and injections sound necessary. Also, it is necessary to find ways for solving problems of urine tests. PMID:24494087

    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

    Background: One of the problems that addicts suffer from is decreased libido. Erectile dysfunction has been reported in men using opioids for treatment of heroin addiction. Objective: The study was performed to investigate the effects of morphine and detoxification with methadone as causes of sexual dysfunction in addiction. Methods and Methods: A total of 40 adult male rats (Wistar) were used. Animals were divided in to 4 groups. Control groups received saline for 30 days. Other 2 groups received 10 mg/kg morphine on day 1 and the morphine doses increased daily by 2 mg/kg increments per day until in day 30 a maximum of 68 mg/kg twice daily was achieved. Withdrawal syndrome sings were evaluated. At the end of period, one group of 2 morphine dependent groups was treated with methadone during 14 days. Animals in group 4 (saline solution+ methadone) received saline for 30 consecutive days and then detoxified with methadone during 14 days. Partial weights of seminal vesicles, testes, prostates, seminal vesicles content, concentrations of luteinizing hormone, follicle stimulating hormone, and testosterone in serum were determined. Results: In the dependent group serum levels of testosterone (p<0.001), folicle stimulating hormone (p=0.0097) and luteinizing hormone (p=0.0031) as well as the weights of testes (p=0.0051), partial weights of prostates, seminal vesicles and seminal vesicles contents (p<0.001) were reduced as compared with control group. In the morphine dependent animals detoxified with methadone, testosterone concentrations and seminal vesicles contents remained lower than levels in the control group (p<0.001). Conclusion: The results suggest that morphine dependence may impair the reproductive function in male rats. PMID:26221126

    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.

    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

    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

    Iatrogenic opioid abstinence syndrome (IOAS) is a common complication in critically ill infants and children receiving prolonged exposure to continuous infusions of opioids. Although no guidelines are available regarding management of IOAS in children, several treatment options are available, including clonidine, morphine, and methadone. Methadone is commonly prescribed due to its long half-life and antagonism of the N-methyl-d-aspartate receptor. Different approaches, such as weight-based and formula-based methods, have been used to determine the initial methadone dosing regimen. Because of the vast differences in the recommended dosing regimen from these sources, we conducted a literature search to identify articles evaluating the initial methadone dosing regimen for prevention and/or treatment of IOAS in children. Specifically, we evaluated the reported frequency of withdrawal and oversedation after initiation of methadone treatment. Our literature search was limited to English-language articles in the MEDLINE (1950-March 2011), EMBASE (1988-March 2011), International Pharmaceutical Abstracts (1970-March 2011), and Cochrane Library (1996-March 2011) databases. Relevant abstracts and reference citations were also reviewed. A total of eight reports representing 183 patients were included in the analysis. There was wide discrepancy in the initial methadone dosing regimen. Approximately one-third of all patients experienced withdrawal after starting methadone, and there did not appear to be a difference between weight-based and formula-based regimens. Seven patients experienced oversedation; however, not all articles reported this complication. It appears that a standard approach to initial methadone dosing does not exist because withdrawal occurred despite the regimen started. Therefore, it seems best to begin with the lowest dose possible and titrate to the child's response to avoid complications such as oversedation. Routine monitoring should be performed in all

    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

    This study examined outcomes and their predictors among 181 probationers enrolling in opioid agonist maintenance with methadone or levo-alpha-acetylmethadol (LAAM). Participants were interviewed at treatment entry and 2-, 6-, and 12-month follow-ups. Treatment retention and frequency of heroin use, cocaine use, and income-generating criminal activity were examined using survival and longitudinal analyses. Participants reported marked reductions in drug use and crime relative to treatment entry. A number of patient characteristics associated with various outcomes were identified. The findings support engaging probationers in treatment and highlight patient factors that might influence outcomes.

    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

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.

    Increasing attention is being focused on hospital-based programs that address the needs of the frail elderly. This article reports results from a demonstration of hospital-based case management (HBCC). Baseline, 3-, 6-, and 12-month assessment data are analyzed to determine why clients terminated from HBCC programs. Subsamples of community- and hospital-originated clients are examined to determine what factors predict case management termination. About half of both hospital- and community-originated clients left case management within 12 months because of death, nursing home placement, referral to another case management agency, relocation out of the service area, or discharge as self-sufficient. Hospital-originated clients were more likely to die within the first 6 months after entering case management than were community-originated clients. Cognitive and functional abilities were important predictors of termination status.

    Unlike research ethics committees, which were created in 1988, the number of functioning hospital based ethical organisations in France, such as clinical ethics committees, is unknown. The objectives of such structures are diverse. A recent law created regional ethical forums, the objectives of which are education, debate, and research in relation to healthcare ethics. This paper discusses the current situation in France and the possible evolution and conflicts induced by this law. The creation of official healthcare ethics structures raises several issues.

    Hospitals often promote healthy lifestyles, but little is known about nurses' actual diet and physical activity. Greater understanding about these lifestyle choices for clinical nurses may improve existing hospital-based programs and/or create desirable services. This article discusses a study that considered diet and physical activity of clinical nurses, using elements of Pender's self-care theory as a conceptual framework. Study methods included a cross-sectional, correlational design and a convenience sample of 278 nurses who worked on units with 24 hours/day and seven days-per-week responsibilities. Participants completed diet and exercise questionnaires about perceptions of attitudes and opinions, barriers, diet benefits/exercise motivators, self-efficacy, and locus of control, and personal and work characteristics. Diet and activity categories were created. Study results demonstrated that over 50% of nurses had moderately healthy diets but were insufficiently active. Healthy diet and physical activity levels were associated with higher self-efficacy, more diet benefits and physical activity motivators, fewer perceived barriers, and confidence in body image. The article discussion and conclusion sections note areas for future research and suggest that focused interventions that address benefits, motivators, and self-efficacy may increase participation in hospital-based programs and enhance healthy lifestyle for hospital-based clinical nurses.

    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: 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

    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.

    All drug-associated deaths from 1989 to 2000 were analysed at the Institute of Forensic Medicine in Cologne. Information concerning sex, gender, drug consumption, time, place and circumstances of death were analysed. A number of 605 cases were recorded; in 518 cases a toxicological analysis was possible and in 171 an autopsy was performed. When it was possible to determine the cause of death form the information available, acute drug intoxication was recorded in 65%. Heroin head the list of identified substances. Sixty-three percent of the specimens showed a combination of several substances, especially a combination of morphine, benzodiazepines, other medications and alcohol. In comparison with other studies the percentage of methadone-positive specimens is low, even though the proportion of specimens positive for methadone increased from 1989 to 2000. This analysis is discussed using background information concerning the management of substitution therapy and the available literature.

    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.

For these men and women in their forties and fifties, their progression to a leadership role helping others with their recovery validated the spiritual transformation they regarded as underlying their own recovery process. Assumption of this new leadership/helper role marked a tangible sign that their deepened spirituality allowed them to assume a new, higher function in a struggle with the addiction that had plagued their lives. For these peer leaders, methadone was at the core of the group experience and an aid to spiritual transformation.

    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

    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

    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

  19. Effect of prenatal methadone and ethanol on opioid receptor development in rats

    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.

  20. 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.

    1999-12-01

    To evaluate the importance of self-help groups and the patients' readiness to participate in such groups a sample of 675 methadone patients in Hamburg was asked by means of questionnaires. 43% of the patients had heard of self-help groups. One quarter of them (10% of the whole sample) had participated in self-help groups at some time. The greatest importance of self-help organisations is attached to a representation of the interests of methadone patients to improve their overall situation. Another important purpose of self-help groups is seen in getting help for legal, financial and social problems. Getting in contact with other clients or offering breakfast/lunch, washing clothes or shower facilities etc. is not evaluated as an important task for self-help organisations. Patients who are working on a regular basis and living in stable conditions are less interested in participating in self-help groups. Thus, the participants in self-help groups can hardly benefit from the experiences of the socially better integrated methadone patients.

    A task-based behavioral contingency-the "treatment reinforcement plan" (TRP)-was implemented with cocaine-using methadone patients to increase treatment engagement and retention. Subjects (N = 57) were rewarded up to $15 per week in travel/food/entertainment vouchers for the completion of tasks related to their individual treatment needs. Eighteen types of tasks were contracted and completed with varying frequency. The largest categories of tasks were related to therapy attendance (N = 272; 58% completed), obtaining public entitlements (N = 165; 61% completed), medical/psychiatric appointments (N = 155; 70% completed), and obtaining Medicaid (N = 96; 54% completed). The highest proportion of tasks completed were related to human immunodeficiency virus (HIV) testing/education (N = 19; 100% completed), managing money (N = 17, 94% completed), and legal matters (N = 16, 88% completed). Successful TRP involvement during months 1-2 predicted longer retention in methadone treatment, greater therapy attendance during months 3-6, and lower proportion of cocaine-positive urines at 6-month follow-up. This research supports recent findings that early treatment engagement is associated with improved therapeutic relationships, increased retention, and reduced cocaine use. Behavioral counseling techniques may be especially helpful in addressing the complex needs of high-risk methadone patients, which in turn may facilitate treatment process and positive outcomes.

    Serotonin syndrome is a syndrome identified by a triad of altered mental status, neuromuscular overactivity, and autonomic instability caused by the overstimulation of serotonin in the central nervous system and periphery. Serotonin syndrome may be provoked with the addition or increase in serotonergic agents such as selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, tricyclic antidepressants, and monoamine oxidase inhibitors as well as other agents with serotonergic properties. Some narcotics, including fentanyl and methadone, have these properties and may be associated with the development of serotonin syndrome when used in conjunction with other agents. Currently, there are no identified case reports of narcotics as the sole agent causing serotonin syndrome. This report provides a brief overview of serotonin syndrome, particularly with cases involving administration of narcotics such as fentanyl and methadone. The case described is the first report associated with fentanyl and methadone without the coadministration of other serotonergic agents, and a possible drug interaction with voriconazole is discussed. This raises awareness of using multiple serotonergic narcotics and the potential precipitation of serotonin syndrome.

    The authors examined the factors associated with methadone patients' decisions about participating in a clinic-based AIDS prevention protocol. Despite the offer of incentives, only 27 percent attended AIDS education and only 12 percent obtained voluntary HIV antibody (ab) testing. However, AIDS education was attended by proportionately more of those who were at highest risk for AIDS because of current intravenous drug use. The availability of HIV-ab testing neither encouraged nor discouraged participation in AIDS education. Patients who were relatively more likely to choose HIV-ab testing were older, had been or were married, had plans to have children, believed the test to be useful, and believed that their counselors support their decision to be tested. Those who declined to be tested were reluctant to confront the emotional aspects of their risk status, were concerned about possible breaches of confidentiality, and doubted the value of testing. The implications of the findings for implementing AIDS prevention measures in methadone programs are discussed. Programs need either to require attendance at AIDS education or give patients an incentive to attend. HIV-ab testing should be available but should remain voluntary. A stronger medical rationale for testing is developing and may increase future participation. Methadone programs must continue to engage patients actively in AIDS risk reduction efforts.

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

    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 article presents the outcomes of an innovative vocational rehabilitation model designed for methadone-maintained patients -- the Customized Employment Supports (CES) model. CES counselors work intensively with a small caseload of patients to overcome the vocational as well as non-vocational barriers that hinder employment, with the goal of attaining rapid job placement. A randomized clinical trial was implemented at two methadone treatment programs in New York City and was funded by the National Institute on Drug Abuse The study tested the hypothesis that patients assigned to the experimental (CES) condition would have better employment outcomes than those assigned to a control condition who received standard vocational counseling at the programs. The data were collected from May 2001 through April 2005. The efficacy sample for the analysis consisted of 168 patients who completed follow-up interviews. The sample was 58% male, 75% minority group, average age 45 years, and in methadone treatment for an average of five years. The results supported the hypothesis for two measures of employment; i.e., the CES group was significantly more likely than the control group to obtain both any paid employment and informal paid employment. However, there were no significant differences for competitive employment or total earnings. The study's limitations are noted. Implications of the findings for the improvement of vocational rehabilitation for addiction patients are discussed.

    Aim To assess the relative frequency of reporting of adverse events involving ventricular arrhythmia, cardiac arrest, QTc prolongation, or torsade de pointes to the US Food and Drug Administration (FDA) between buprenorphine and methadone. Design Retrospective pharmacoepidemiologic study Setting Adverse drug events spontaneously reported to the FDA between 1969-June 2011 originating in 196 countries (71% events from the US). Cases Adverse event cases mentioning methadone (n=14,915) or buprenorphine (n=7,283) were evaluated against all other adverse event cases (n= 4,796,141). Measurements The primary outcome was the composite of ventricular arrhythmia or cardiac arrest. The secondary outcome was the composite of QTc prolongation or torsade de pointes. The proportional reporting ratio (PRR) was used to identify disproportionate reporting defined as a PRR>2, χ2 error>4, with ≥3 cases. Findings There were 132 (1.8%) ventricular arrhythmia/cardiac arrest and 19 (0.3%) QTc prolongation/torsade de pointes cases associated with buprenorphine compared with 1729 (11.6%) ventricular arrhythmia/cardiac arrest and 390 (2.6%) QTc prolongation/torsade de pointes cases involving methadone. PRRs associated with buprenorphine were not significant for ventricular arrhythmia/cardiac arrest (1.1 95% confidence interval (CI) 0.9–1.3, χ2=1.2) or QTc prolongation/torsade de pointes (1.0 95% CI 0.7–1.9, χ2=0.0006), but were for methadone (7.2 95% CI 6.9–7.5, χ2=9160; 10.6 95% CI 9.7–11.8, χ2=3305, respectively). Conclusion In spontaneously reported adverse events, methadone is associated with disproportionate reporting of cardiac arrhythmias, whereas buprenorphine is not. Although these findings probably reflect clinically relevant differences, a causal connection cannot be presumed and disproportionality analysis cannot quantify absolute risk per treatment episode. Population-based studies to definitively quantify differential incidence rates are warranted. PMID:26075588

    A number of studies point to methadone exposure in utero as a possible risk factor in the developing mother-infant relationship in the first year of life. This study is part of a larger, national follow-up of 38 infants prenatally exposed to methadone or buprenorphine and 36 comparison, low-risk infants. The aim of the present paper is to assess the quality of mother-infant relationship when the infants are 6 months old. Videotaped mother-infant interactions were rated in a global scale (NICHD). Maternal and infant contributions collapsed into the variables "infant style" and "maternal style" showed that the only factor making significant contribution to the outcome measure "dyadic mutuality" was maternal style. The importance of group membership (exposed versus non-exposed), was reduced when controlling for maternal drug use prior to opioid maintenance treatment (OMT), maternal depression and parenting stress as well as infants' developmental status and sensory-integrative functions. This suggests that prediction of dyadic mutuality should be based on individual characteristics rather than group characteristics. These results support previous research findings that methadone and buprenorphine use per se does not have direct influence on the quality of early mother-infant relationship, but tailored follow-up procedures targeting drug-free pregnancies and parenting support are beneficial for women in OMT and their children.

    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.

    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

    Aims: (1) To measure the prevalence of burnout, psychological morbidity, job satisfaction, job stress, and consideration of alternate work among multidisciplinary hospital based child and youth protection (CYP) professionals; (2) to understand the relations between these variables; and (3) to understand the reasons for leaving among former programme members. Methods: Mailed survey of current and former members of all Canadian academic hospital based CYP programmes. Surveys for current members contained validated measures of burnout, psychological morbidity, job satisfaction/stress, and questions about consideration of alternate work. Surveys for former members examined motivation(s) for leaving. Results: One hundred and twenty six of 165 current members (76.4%) and 13/14 (92.9%) former members responded. Over one third (34.1%) of respondents exhibited burnout while psychological morbidity was present in 13.5%. Job satisfaction was high, with 68.8% finding their job "extremely" or "quite" satisfying, whereas 26.2% found their job "extremely" or "quite" stressful. Psychological morbidity, job satisfaction, and job stress were not associated with any of the demographic variables measured, but burnout was most prevalent among non-physician programme members. Almost two thirds of current members indicated that they had seriously considered a change in work situation. Former members indicated that burnout and high levels of job stress were most responsible for their decision to leave and that increasing the number of programme staff and, consequently, reducing the number of hours worked would have influenced their decision to stay. Conclusions: Current levels of burnout and the large proportion of individuals who have contemplated leaving the service suggest a potential crisis in Canadian hospital based CYP services.

    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.

    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

    Poultry-borne salmonellosis is the most common form of foodborne infection in Scotland for which the vehicle can be identified, yet little is known about the costs imposed on society by this disease, or the costs of preventing it. The present study identifies and values the costs of a hospital based outbreak of poultry-borne salmonellosis. Account is taken of costs falling on individuals, the health services and society as a whole. Depending on assumptions made about the value of 'intangibles', the cost of the outbreak is estimated to be between pounds 200,000 and pounds 900,000. PMID:3338505

    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.

    On September 25th, 1987 methadone was legalized in Austria for therapeutic use in drug addiction treatment in case of: 1. Long-term drug addiction with intravenous application of the drug, and several unsuccessful withdrawal therapies and/or 2. opiate addiction through intravenous application of the drug along with an existing HIV-1 infection. Since than, 291 patients were treated with methadone at the drug-dependency outpatient clinic of the Psychiatric Clinic of the University of Vienna. In 1990, 96 patients treated for more than one year were investigated using a standardized questionnaire. The image in which crime, prostitution, poverty, ill health all merge was broken by this decriminalization. Methadone treatment offers a first step toward social rehabilitation for drug addicts who have been living as criminals on the fringe of society.

    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

    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.

    The purpose of this study is to explore the factors associated with outsourcing of information systems (IS) in hospital-based health care delivery systems, and to determine if there is a difference in IS outsourcing activity based on the strategic value of the outsourced functions. IS sourcing behavior is conceptualized as a case of vertical integration. A synthesis of strategic management theory (SMT) and transaction cost economics (TCE) serves as the theoretical framework. The sample consists of 1,365 hospital-based health care delivery systems that own 3,452 hospitals operating in 2004. The findings indicate that neither TCE nor SMT predicted outsourcing better than the other did. The findings also suggest that health care delivery system managers may not be considering significant factors when making sourcing decisions, including the relative strategic value of the functions they are outsourcing. It is consistent with previous literature to suggest that the high cost of IS may be the main factor driving the outsourcing decision.

    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

    BACKGROUND Untreated opioid dependence in pregnant women is associated with adverse birth outcomes. Buprenorphine and methadone are options for opioid agonist medication-assisted treatment during pregnancy. OBJECTIVE The aim of this study was to describe adverse birth outcomes observed with buprenorphine or methadone treatment compared to the general population in Sweden. METHODS Pregnant women and their corresponding births during 2005–2011 were identified in the Swedish Medical Birth Register. Data on stillbirth, neonatal/infant death, mode of delivery, gestational age at birth, Apgar score, growth outcomes, neonatal abstinence syndrome, and congenital malformations were examined. Frequencies were compared using two-sided Fisher’s exact tests. Unadjusted estimates of birth outcomes for women treated with buprenorphine or methadone were compared to the registered general population. RESULTS A total of 746,257 pregnancies among 538,178 unique women resulted in 746,485 live births. Among the 194 women treated with buprenorphine (N = 176) or methadone (N = 52), no stillbirths or neonatal/infant deaths occurred. Neonatal abstinence syndrome developed in 23.3% and 38.5% of infants born to mothers treated with buprenorphine and methadone, respectively. The frequency of the selected adverse birth outcomes assessed in women treated with buprenorphine as compared to the general population was not significantly different. However, a significantly higher frequency of preterm birth and congenital malformations was observed in women treated with methadone as compared to the general population. Compared with the general population, methadone-treated women were significantly older than buprenorphine-treated women, and both treatment groups began prenatal care later, were more likely to smoke cigarettes, and did not cohabitate with the baby’s father. CONCLUSIONS An increased frequency of the selected adverse birth outcomes was not observed with buprenorphine treatment

    The present study aims to explore whether an impairment in emotional facial expressions (EFE) decoding is specific to alcoholism compared with opiate dependence. An EFE decoding test consisting of 16 photographs of EFE portraying happiness, anger, sadness and disgust was administered to five different groups of 30 subjects each: recently detoxified alcoholics (RA); opiate addicts under methadone maintenance treatment (OM); detoxified opiate addicts (OA); detoxified subjects with both alcohol and opiate dependence antecedents (DAO); and normal controls (NC). Repeated measures analysis of variance using a multivariate approach was conducted on EFE decoding accuracy scores with group as the between-subjects factor. Accuracy scores were significantly lower in RA and DAO than in OM and OA, which had significantly lower scores than NC. Low accuracy scores in RA and DAO confirm previous results indicating that alcoholism is associated with impaired EFE recognition. Results in OM and OA indicate that opiate dependence is also associated with an impaired EFE decoding but less than in alcoholism. Alcohol and opiate chronic consumption could both exercise a deleterious effect on EFE-decoding brain function, alcohol having the most severe impact. Alternatively, EFE-decoding problems could be present before the development of alcohol and opiate dependence, with an additional effect of chronic alcohol consumption on EFE decoding. In this context, EFE-decoding impairment could reflect a more general emotional intelligence deficit in addicted populations.

    Developmental features of the P2 auditory ERP in a change detection paradigm were examined in infants prenatally exposed to methadone. Opiate dependent pregnant women maintained on methadone replacement therapy were recruited during pregnancy (N = 60). Current and historical alcohol and substance use, SES, and psychiatric status were assessed with a maternal interview during the third trimester. Medical records were used to collect information regarding maternal medications, monthly urinalysis, and breathalyzer to confirm comorbid drug and alcohol exposures. Between birth and 4 months infant ERP change detection performance was evaluated on one occasion with the oddball paradigm (.2 probability oddball) using pure-tone stimuli (standard = 1 kHz and oddball = 2 kHz frequency) at midline electrode sites, Fz, Cz, Pz. Infant groups were examined in the following developmental windows: 4-15, 16-32, or 33-120 days PNA. Older groups showed increased P2 amplitude at Fz and effective change detection performance at P2 not seen in the newborn group. Developmental maturation of amplitude and stimulus discrimination for P2 has been reported in developing infants at all of the ages tested and data reported here in the older infants are consistent with typical development. However, it has been previously reported that the P2 amplitude difference is detectable in neonates; therefore, absence of a difference in P2 amplitude between stimuli in the 4-15 days group may represent impaired ERP performance by neonatal abstinence syndrome or prenatal methadone exposure.

  14. 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

    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.

    Primary immunodeficiency disorders (PID) are under-reported from the developing world. We present data regarding diagnosis and outcome from a hospital-based registry in India. Forty-seven patients fulfilled diagnostic criteria. Majority were males. Subgroups were disorders of immune dysregulation-29%, B&T-cell abnormalities-28%, predominant antibody deficiencies-23%, other well-defined immunodeficiencies-15%, and phagocyte disorders-4%. Molecular diagnosis was attempted in 12 and was positive in seven. Overall 24 children died. Only three out of 28 children needing stem cell transplant (SCT) underwent the same. Registry data highlights that molecular diagnosis and SCT are a rarity for children with PIDs in the developing world and mortality is high.

    The authors' hospital embarked on a three-component, multidisciplinary, hospital-based antimicrobial use program to cut costs and reduce inappropriate antimicrobial use. Initially, antimicrobial use patterns and costs were monitored for 12 months. For the next two years, an antimicrobial use program was implemented consisting of three strategies: automatic therapeutic interchanges; antimicrobial restriction policies; and parenteral to oral conversion. The program resulted in a reduction in the antimicrobial portion of the total pharmacy drug budget from 41.6% to 28.2%. Simultaneously, the average cost per dose per patient day dropped from $11.88 in 1991 to $10.16 in 1994. Overall, mean monthly acquisition cost savings rose from $6,810 in 1992 to $27,590 in 1994. This study demonstrates that a multidisciplinary antimicrobial use program in a Canadian hospital can effect dramatic cost savings and serve as a quality assurance activity of physician antimicrobial prescribing behaviour.

    Innovative medical devices offer solutions to medical problems and greatly improve patients' outcomes. Like National Health Technology Assessment (HTA) agencies, hospitals face numerous requests for innovative and costly medical devices. To help local decision-makers, different approaches of hospital-based HTA (HB-HTA) have been adopted worldwide. The objective of the present paper is to explore HB-HTA models for adopting innovative medical devices in France and elsewhere. Four different models have been conceptualized: "ambassador" model, "mini-HTA" model, "HTA unit" model and "internal committee". Apparently, "HTA unit" and "internal committee" (or a mixture of both models) are the prevailing HB-HTA models in France. Nevertheless, some weaknesses of these models have been pointed out in previous works. Only few examples involving hospital pharmacists have been found abroad, except in France and in Italy. Finally, the harmonization of the assessment of innovative medical devices in France needs a better understanding of HB-HTA practices.

    The Beaumont Health System BioBank was established in 2008, not only to leverage the potential to collect biospecimens for translational research, but to undertake such research in a seamless facility that combined high quality biobanking with state-of-the-art laboratory platforms geared towards biospecimen-based research. This report describes the challenge of sustaining a hospital-based biobank with an operating budget exceeding $1,000,000 in a financial climate that favors short-term fiscal goals rather than long-term scientific ambitions. Some of the key areas that are discussed include grants, philanthropy, accreditation, process improvement and commercialization of samples and services. We conclude that grants are not a feasible avenue, in our case, to support a biobank and that philanthropy and commercialization represent the best options for external funding to support stalling internal support, in order to sustain the operations of the BioBank.

    This paper examines current advances in hospital-based patient education, and delineates the role of the hospital librarian in these programs. Recently, programs of planned patient education have been recognized by health care personnel and the public as being an integral part of health care delivery. Various key elements, including legislative action, the advent of audiovisual technology, and rising health care costs have contributed to the development of patient education programs in hospitals. As responsible members of the hospital organization, hospital librarians should contribute their expertise to patient education programs. They are uniquely trained with skills in providing information on other health education programs; in assembling, cataloging, and managing collections of patient education materials; and in providing documentation of their use. In order to demonstrate the full range of their skills and to contribute to patient care, education, and research, hospital librarians should actively participate in programs of planned patient education.

    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.

    To determine the prevalence of dry eye diseases in general clinical ophthalmic practice in a hospital-based population in West Bengal, Eastern India, a cross-sectional study was undertaken among 3023 subjects with the age of > or = 30 years, attending general ophthalmic clinic in a tertiary eye hospital. Demographics, detailed history and 6-items McMonnies' dry eye questionnaire were asked. Tear film break-up time (TBUT), Schirmer-I test, Rose Bengal (RB) staining, slit lamp examination and Meibomian gland dysfunction (MGD) were studied. Dry eye diseases were significantly higher in women than in men ie, 51.9% versus 48.1% (p < 0.01). Symptom-based dry eye (one or more symptoms present often or most of the time) was diagnosed in 1234 subjects (40.8%). With symptoms and at least one sign [TBUT < 10 seconds, RB staining (van Bjisterveld score: 4 or more) and Schirmer-I test = 5 mm in 5 minutes], the prevalence of dry eye was 786 (26%). Different grades of MeibOmian gland dysfunction (MGD) were detected in 957 cases (31.7%). Primary Sjogren syndrome was found in 21.5%; and 10.9% patients of dry eye had some form of systemic collagen vascular disorders. Using computers was not a risk factor in this geographical area. No significant correlation was seen between significant symptoms and positive signs in the study population. The prevalence of dry eye disease is high in West Bengal, Eastern India in hospital-based population. The risk is higher with age, female gender, systemic collagen diseases and with oral antidepressant/anxiolytic medication. Meibomian gland dysfunction is found to be common among dry eye subjects.

    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

    Knowledge concerning the distribution of methadone in postmortem human tissue and the effect of postmortem redistribution on methadone is today limited making the choice of a suitable substitute for femoral blood difficult when this is not available. Cardiac blood, femoral blood, muscle, and brain tissue concentrations of the enantiomers of methadone and its metabolite 2-ethyl-1,5-dimethyl-3,3-diphenylpyrrolinium were recorded for 155 postmortem cases. Brain and muscle tissue concentrations exceeded the femoral blood concentrations with a median fold of 2.3 and 1.6, respectively, but both had a better correlation than cardiac blood to femoral blood concentrations. The Kruskal-Wallis test showed a significant dependency on time and body mass index for some of the matrix ratios over femoral blood. We conclude brain or muscle tissue may constitute a better alternative for measurement of methadone than cardiac blood for situations in which femoral blood is not available, despite concentrations in both matrices being systematically higher.

    The efficacy of clonidine, methadone, and guanfacine in rapid detoxification of heroin inpatients was assessed in a randomized controlled clinical trial. Signs and symptoms of abstinence and of side effects were analysed in 90 heroin addicts successfully completing a 12-day inpatient trial. All patients fit DSM-III criteria for opioid dependence, the age range being 18 to 36 years. All three drugs were effective in controlling abstinence; however, the course of abstinence was different in the methadone group as compared to the adrenergic agonists, the latter showing limitations in their ability to suppress withdrawal manifestations. While mean number of withdrawal signs and symptoms was significantly lower during days 2 to 5 in the methadone group (p less than 0.01), adrenergic agonists were slightly more effective at the end of the trial. Incidence of side effects was closely related to the dose administered. Hypotensive action of adrenergic agonists was more marked in orthostatic position. The present results suggest that methadone is superior to adrenergic agonists. Between these drugs clonidine appears to be less effective than guanfacine in controlling some withdrawal manifestations, and causes more side effects, mainly of cardiovascular nature.

    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.

    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

    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.

    SYNOPSIS Objective To (1) examine the subjective experience of parenting stress as a mediator between 2 distal stressors (sociodemographic risk and global psychological maladjustment), and examine the parenting of methadone-maintained mothers, and (2) identify maladaptive and adaptive parenting correlates of specific types of parenting stress. Design We analyzed baseline data from interviews conducted with 74 methadone-maintained mothers who expressed interest in a randomized clinical trial study testing the efficacy of a relational parenting intervention. Baseline measures included questionnaires on maternal psychological maladjustment, parenting stress, parenting problems, and children’s maladjustment. Three series of hierarchical linear regressions were conducted to test the mediation model and specificity of associations. Results Parenting stress mediated the associations between sociodemographic risk and 2 maladaptive parenting domains (aggression and neglect) and between psychological maladjustment and all 5 parenting domains examined (aggression, neglect, affective interactions, limit setting, and autonomy), although correlations were modest. Child-focused stress was associated with higher levels of aggression, limit-setting problems, and restricted autonomy. Stress derived from the mother – child relationship was associated with higher levels of neglect and affective withdrawal. Conclusions Although preliminary in nature, results of this study indicate the importance of understanding the role of internal mechanisms (e.g., parenting stress) in the parenting processes of addicted women and examining specific correlates of their parenting problems.

    BACKGROUND While agonist replacement therapies are effective for managing opioid dependence, community treatment programs are increasingly choosing detoxification. Unfortunately, success rates for opioid detoxification are very low, in part, due to physical and psychological symptoms associated with opioid withdrawal. Few behavior therapies specifically address the distressing experiences specific to opioid withdrawal. A novel behavioral treatment, Acceptance and Commitment Therapy (ACT), works from the premise that the avoidance of unpleasant private experiences (thoughts, feelings, bodily sensations) is ubiquitous yet may be pathogenic, resulting in treatment drop-out and further drug use. METHODS This Stage I pilot study developed and tested an ACT-based opioid detoxification behavioral therapy. Opioid dependent patients (N = 56) who were attending a licensed methadone clinic were randomized to receive either 24 individual therapy sessions of ACT or Drug Counseling (DC) in the context of a 6-month methadone dose reduction program. RESULTS While no difference was found on opioid use during treatment, 37% of participants in the ACT condition were successfully detoxified at the end of treatment compared to 19% of those who received DC. Fear of detoxification was also reduced across time in the ACT condition relative to DC. CONCLUSION This first study of ACT to assist opioid detoxification indicates promise. Research is needed to refine specific treatment strategies for this population to further strengthen effects. PMID:22425411

    This study investigates the association between cigarette use and current mood/anxiety disorders among pregnant opioid-dependent patients. Pregnant methadone-maintained women (N = 122) completed the Addiction Severity Index and Structured Clinical Interview for DSM-IV. Participants were categorized based on past 30 days cigarette use: no (n = 15) and any smoking (n = 107); this latter group was then subdivided into light (one to ten cigarettes/day; n = 55), and heavy smokers (11+ cigarettes/day; n = 52). Any smoking was significantly associated with any current mood/anxiety disorder (p < 0.001), any current mood disorder (p = 0.007), and any current anxiety disorder (p < 0.001). No significant association was found between specific level of cigarette use and mood/anxiety disorders. This association between smoking and psychiatric disorders has implications for the mental and physical health of methadone-maintained women and their children, and may contribute to the understanding of the physiological mechanisms underlying smoking and nicotine dependence.

    Methadone is widely used in treatment of short-acting opiate addiction. The on-off effects of opioids have been documented to have profound differences from steady-state opioids. We hypothesize that opioids play important roles in either generalized arousal (GA) or aversive state of arousal during opioid withdrawal. Both male and female C57BL6 mice received steady-state methadone (SSM) through osmotic pumps at 10 or 20 mg/kg/day and GA was measured in voluntary motor activity, sensory responsivity, and contextual fear conditioning. SSM did not have any effect on those GA behaviors in either sex. Females had higher activity and less fear conditioning than males. The effects of SSM on stress responsive orexin gene expression in the lateral hypothalamus (LH) and medial hypothalamus (MH, including perifornical and dorsomedial areas) were measured after the behavioral tests. Females showed significantly lower basal LH (but not MH) orexin mRNA levels than males. A panel of GA stressors increased LH orexin mRNA levels in females only; these increases were blunted by SSM at 20 mg/kg. In summary, SSM had no effect on GA behaviors. In females, SSM blunted the GA stress-induced LH orexin gene expression. PMID:19045944

    Increasing the availability of, and streamlining the admissions process to, methadone treatment have consistently been the focus of national plans to address the acquired immune deficiency syndrome (AIDS) epidemic. This article uses simplified time-series analysis to evaluate one of the first methadone treatment Waiting List Reduction Demonstration Grants. The demonstration grant significantly increased both the number of people requesting intake appointments from 35 to 100 per month and the percentage of kept appointments from 33% to 54%. An additional 100 slots (an entire year's waiting list) were filled in fewer than three months and actually resulted in a net increase in the length of the waiting list. Relative to the preceding two years, new clients during the grant period were significantly more likely to be 41 or older, African-American, unemployed, daily opioid users, daily cocaine users, and dependent on public assistance to finance treatment. Controlling for the source of treatment financing (a case-mix adjustment), there were no significant changes in retention rates. The program's static client capacity rose from 310 prior to the grant to a peak of 449 during the grant, with a leveling to 410 after the grant. Given that it is clearly more humane and less expensive to treat people who want treatment rather than wait for them to commit a crime and be arrested or even executed, this study strongly suggests the need to make more treatment available on demand.

    Background Drug abuse is a major public health problem. Some believe that when dissociation fails to defend against emotional, physical, or sexual trauma, the person will find relief from unpleasant thoughts and emotions in opium use. On the other hand, personality disorders are considered as important predictors of treatment outcomes in drug abusers. Due to lack of adequate research in this regard, we evaluated dissociative disorders and personality traits of opium addicts on methadone treatment. Methods This cross-sectional analytic study included 111 non-psychotic subjects on methadone treatment (case group) and 69 non-addicts (control group). After recording demographic characteristics, Dissociative Experiences Scale (DES) and Millon Multiaxial Inventory III were applied to assess dissociative symptoms and clinical personality patterns of all participants. Findings Dissociative symptoms were significantly more common in the case group than in the control group (P = 0.044). While hysterionic personality disorder was more frequent in the control group (P = 0.008), sadistic, antisocial, and schizotypal personality disorders were significantly more common in the case group (P = 0.008, 0.002, and 0.023, respectively). Conclusion We found relations between history of drug dependence, dissociative symptoms, and personality disorders. Therefore, the mentioned disorders need to be kept in mind while planning addiction treatment modalities and identifying high risk groups. PMID:24494154

    Objective Septic shock is associated with increased long-term morbidity and mortality. However, little is known about the use of hospital-based acute care in survivors after hospital discharge. The objectives of the study were to examine the frequency, timing, causes, and risk factors associated with Emergency Department (ED) visits and hospital readmissions within 30 days of discharge. Design Retrospective cohort study. Setting Tertiary, academic hospital in the United States. Patients Patients admitted with septic shock (serum lactate ≥ 4 mmol/L or refractory hypotension) and discharged alive to a non-hospice setting between 2007 and 2010. Interventions None. Measurements and Main Results The co-primary outcomes were all-cause hospital readmission and ED visits (treat-and-release encounters) within 30 days to any of the three health system hospitals. Of 269 at-risk survivors, 63 (23.4%, 95% confidence interval (CI): 18.2, 28.5) were readmitted within 30 days of discharge and another 12 (4.5%, 95% CI: 2.3, 7.7) returned to the ED for a treat-and-release visit. Readmissions occurred within 15 days of discharge in 75% of cases and were more likely in oncology patients (p=0.001) and patients with a longer hospital length of stay (p=0.04). Readmissions were frequently due to another life-threatening condition and resulted in death or discharge to hospice in 16% of cases. The reasons for readmission were deemed potentially related to the index septic shock hospitalization in 78% (49/63) of cases. The most common cause was infection-related, accounting for 46% of all 30-day readmissions, followed by cardiovascular or thromboembolic events (18%). Conclusions The use of hospital-based acute care appeared to be common in septic shock survivors. Encounters often led to readmission within 15 days of discharge, were frequently due to another acute condition, and appeared to result in substantial morbidity and mortality.

    2016-01-01

    Background: Tattooing has become increasingly popular, particularly among young people. However, little is known about the tattoo practices in North-East India. Objectives: The primary objective of this study was to know the reasons and motivations of tattoo application and tattoo removal in individuals asking for tattoo removal. The secondary objective was to identify the demography, methods and safety of tattoo practices in these tattooed individuals. Materials and Methods: A hospital-based cross-sectional study was carried out in 212 consecutive individuals seeking tattoo removal. Chi-square and Fisher's exact tests were performed for intergroup comparisons. Results: There were 178 (84%) males and 34 (16%) females. The mean ± standard deviation (SD) age of individuals seeking tattoo removal was 21.8 ± 4 years. The mean ± SD age of doing tattoo was 15.8 ± 3 years. Most individuals possessed an amateur tattoo (94.3%), 4.2% a professional one and 1.4% had a combination. Sewing needle was the most common instrument used for making tattoos in 51.4%. The individuals made their tattoos in an unsterile manner in 49.1%. The most common reason for doing tattoo was for fashion in 87.7%. The participants wanted tattoo removal to qualify for jobs, especially in armed forces in 49.5% and due to regret in 21.7%. Black was the most preferred colour in 37.3% followed by green in 28.3%. The fabric ink was the choice of ink in maximum number of individuals, i.e. 93.9%. Limitations: It was a hospital-based study done only on individuals seeking tattoo removal. It needs caution to generalise the findings in population. In addition, there may be recall bias in the participants. Conclusion: The tattoo was done mostly below 18 years of age in a crude unsterile way. The individuals had poor risk perceptions about various infections and complications of tattooing. There is an urgent need to caution and educate the youngsters and school-going children about safe tattooing and

    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)

    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.

    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.

    Objective To examine the effect of reductions in hospital-based (HB) skilled nursing facility (SNF) bed supply on the rate of rehospitalization of patients discharged to any SNF from zip codes that lost HB beds. Data Source We used Medicare enrollment records, Medicare hospital and SNF claims, and nursing home Minimum Dataset assessments and characteristics (OSCAR) to examine nearly 10 million Medicare fee-for-service hospital discharges to SNFs between 1999 and 2006. Study Design We calculated the number of HB and freestanding (FS) SNF beds within a 22 km radius from the centroid of all zip codes in which Medicare beneficiaries reside in all years. We examined the relationship between HB and FS bed supply and the rehospitalization rates of the patients residing in corresponding zip codes in different years using zip code fixed effects and instrumental variable methods including extensive sensitivity analyses. Principal Findings Our estimated coefficients suggest that closure of 882 HB homes during our study period resulted in 12,000–18,000 extra rehospitalizations within 30 days of discharge. The effect was largely concentrated among the most acutely ill, high-need patients. Conclusions SNF patient-based prospective payment resulted in closure of higher cost HB facilities that had served most postacute patients. As other, less experienced SNFs replaced HB facilities, they were less able to manage high acuity patients without rehospitalizing them. PMID:23033808

    Background Regret is an unavoidable corollary of clinical practice. Physicians and nurses perform countless clinical decisions and actions, in a context characterised by time pressure, information overload, complexity and uncertainty. Objective To explore feelings associated with regretted clinical decisions or interventions of hospital-based physicians and nurses and to examine how these regrets are coped with. Method Qualitative study of a volunteer sample of 12 physicians and 13 nurses from Swiss University Hospitals using semi-structured interviews and thematic analysis Results All interviewees reported at least one intense regret, which sometimes led to sleep problems, or taking sickness leave. Respondents also reported an accumulation effect of small and large regrets, which sometimes led to quitting one's unit or choosing another specialty. Respondents used diverse ways of coping with regrets, including changing their practices and seeking support from peers and family but also suppression of thoughts related to the situation and ruminations on the situation. Another coping strategy was acceptance of one's limits and of medicine's limits. Physicians reported that they avoided sharing with close colleagues because they felt they could lose their credibility. Conclusions Since regret seems related to both positive and negative consequences, it is important to learn more about regret coping among healthcare providers and to determine whether training in coping strategies could help reduce negative consequences such as sleep problems, absenteeism, or turnover.

    Within the hospital based imaging department at Methodist Willowbrook, outpatient, inpatient, and emergency patients are all performed on the same equipment with the same staff. The critical nature of the patient is the deciding factor as to who gets done first and in what order procedures are performed. After an aggressive adoption of Intentional Tools, the imaging department was finally able to move from a two year mean Press Ganey, outpatient satisfaction average score of 91.2 and UHC percentile ranking of 37th to a mean average of 92.1 and corresponding UHC ranking of 60th percentile. It was at the 60th percentile ranking that the department flat lined. Using the Six Sigma DMAIC process, opportunity for further improvement was identified. A two week focus pilot was conducted specifically on areas identified through the Six Sigma process. The department was able to jump to 88th percentile ranking and a mean of 93.7. With pay for performance focusing on outpatient satisfaction and a financial incentive to improving and maintaining the highest scores, it was important to know where the imaging department should apply its financial resources to obtain the greatest impact.

    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

    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

    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.

    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

    Japanese encephalitis virus (JEV) is endemic in the Philippines but the incidence and burden of disease are not well established. We conducted a prospective hospital-based study at San Lazaro Hospital, a tertiary level hospital in Manila, from September 2005 to December 2006. Cases were determined using an in-house dengue and Japanese encephalitis (JE) enzyme-linked immunosorbent assay in order to detect the proportion of JE cases among the acute encephalitis syndrome (AES) cases admitted to our hospital. Fifteen patients were found to have AES, of whom 6 (40%) had confirmed JE. Of the JE cases, 4 were females and 2 were males with an age range of 3-14 years. Three of the 6 JE cases occurred during July. The most common signs and symptoms on admission among JE cases were: fever, headache, loss of appetite, neck rigidity and altered sensorium. JE likely comprises a significant proportion of hospitalized AES cases among children from Manila and nearby provinces. Further studies on the nation-wide prevalence and distribution of JE in the Philippines are needed to guide health authorities in disease control and prevention strategies.
