Aim: In this paper, we aim to provide an updated source of information for nonmedical prescribing (NMP) in New Zealand (NZ). Methods: A variety of NZ sources were used to collect data: legislation, policy documents and information from professional and regulatory organizations, and education providers. Results: In NZ, the legal categories for prescribers include authorized, designated, and delegated prescribers. Authorized prescribers include dentists, midwives, nurse practitioners, and optometrist prescribers. Designated prescribers include pharmacist prescribers, registered nurse prescribers, and dietitian prescribers. There are no delegated prescribers in NZ at this time. There is variation in the regulation, educational programmes and prescribing competencies used by the different prescribing health professionals involved in NMP in NZ. Conclusion: This update collates relevant information relating to NMP in NZ into one consolidated document and provides policy makers with a current overview of prescribing rights, service delivery models, training requirements, and prescribing competencies used for NMP in NZ. As NMP in NZ continues to expand and evolve, this paper will form a baseline for future NMP research in NZ. NZ needs to develop overarching NMP policy to enable consistency in the various aspects of NMP, thereby delivering a safe and sustainable NMP service in NZ. PMID:29090084

Inappropriate prescribing is a major health care issue, especially regarding older patients on polypharmacy. Multiple implicit and explicit prescribing tools have been developed to improve prescribing, but these have hardly ever been used in combination. The Systematic Tool to Reduce Inappropriate Prescribing (STRIP) combines implicit prescribing tools with the explicit Screening Tool to Alert physicians to the Right Treatment and Screening Tool of Older People's potentially inappropriate Prescriptions criteria and has shared decision-making with the patient as a critical step. This article describes the STRIP and its ability to identify potentially inappropriate prescribing. The STRIP improved general practitioners' and final-year medical students' medication review skills. The Web-application STRIP Assistant was developed to enable health care providers to use the STRIP in daily practice and will be incorporated in clinical decision support systems. It is currently being used in the European Optimizing thERapy to prevent Avoidable hospital admissions in the Multimorbid elderly (OPERAM) project, a multicentre randomized controlled trial involving patients aged 75 years and older using multiple medications for multiple medical conditions. In conclusion, the STRIP helps health care providers to systematically identify potentially inappropriate prescriptions and medication-related problems and to change the patient's medication regimen in accordance with the patient's needs and wishes. This article describes the STRIP and the available evidence so far. The OPERAM study is investigating the effect of STRIP use on clinical and economic outcomes. © 2017 John Wiley & Sons, Ltd.

Prescribing is a core activity for general practitioners, yet significant variation in the quality of prescribing has been reported. This suggests there may be room for improvement in the application of the current best research evidence. There has been substantial investment in technologies and interventions to address this issue, but effect sizes so far have been small to moderate. This suggests that prescribing is a decision-making process that is not sufficiently understood. By understanding more about prescribing processes and the implementation of research evidence, variation may more easily be understood and more effective interventions proposed. An ethnographic study in three Scottish general practices with diverse organizational characteristics. Practices were ranked by their performance against Audit Scotland prescribing quality indicators, incorporating established best research evidence. Two practices of high prescribing quality and one practice of low prescribing quality were recruited. Participant observation, formal and informal interviews, and a review of practice documentation were employed. Practices ranked as high prescribing quality consistently made and applied macro and micro prescribing decisions, whereas the low-ranking practice only made micro prescribing decisions. Macro prescribing decisions were collective, policy decisions made considering research evidence in light of the average patient, one disease, condition, or drug. Micro prescribing decisions were made in consultation with the patient considering their views, preferences, circumstances and other conditions (if necessary).Although micro prescribing can operate independently, the implementation of evidence-based, quality prescribing was attributable to an interdependent relationship.

The drug use process suffers from problems related to quality and cost that have not responded well to administrative or educational interventions. In many cases, attempts to improve the quality of physician prescribing have been clumsy, often based on intuition. This article begins by describing the drug use process and the role of prescribing in that process. In the following section, we describe what is known about how physicians make drug choice decisions. The paper concludes with suggestions, based on evidence, about the design of strategies for influencing prescribing.

In March of 2015, the United States Department of Health and Human Services identified 3 priority areas to reduce opioid use disorders and overdose, which are as follows: opioid-prescribing practices; expanded use and distribution of naloxone; and expansion of medication-assisted treatment. In this narrative review of overdose prevention and the role of prescribers and pharmacists in distributing naloxone, we address these priority areas and present a clinical scenario within the review involving a pharmacist, a patient with chronic pain and anxiety, and a primary care physician. We also discuss current laws related to naloxone prescribing and dispensing. This review was adapted from the Prescribe to Prevent online continuing medical education module created for prescribers and pharmacists (http://www.opioidprescribing.com/naloxone_module_1-landing).

Electronic prescribing has improved the quality and safety of care. One barrier preventing widespread adoption is the potential detrimental impact on workflow. We used time-motion techniques to compare prescribing times at three ambulatory care sites that used paper-based prescribing, desktop, or laptop e-prescribing. An observer timed all prescriber (n = 27) and staff (n = 42) tasks performed during a 4-hour period. At the sites with optional e-prescribing >75% of prescription-related events were performed electronically. Prescribers at e-prescribing sites spent less time writing, but time-savings were offset by increased computer tasks. After adjusting for site, prescriber and prescription type, e-prescribing tasks took marginally longer than hand written prescriptions (12.0 seconds; -1.6, 25.6 CI). Nursing staff at the e-prescribing sites spent longer on computer tasks (5.4 minutes/hour; 0.0, 10.7 CI). E-prescribing was not associated with an increase in combined computer and writing time for prescribers. If carefully implemented, e-prescribing will not greatly disrupt workflow.

Socioeconomic determinants of prescribed and non-prescribed medicine consumption in Austria.

Equitable access to health care is a goal subscribed to in many European economies. But while a growing body of literature studies socioeconomic inequalities in health service use, relatively little is still known about inequalities in medicine consumption. Against this background, this study investigates the (socioeconomic) determinants of medicine use in the Austrian context. Multivariate logistic regressions were estimated based on the European Health Interview Survey, including representative information of the Austrian population above age 25 (n = 13 291) for 2006/2007. As dependent variables, we used prescribed and non-prescribed medicine consumption as well as prescribed polypharmacy. Socioeconomic status was operationalized by employment status, education and net equivalent income. Health indicators (self-assessed health, chronic conditions), demographic characteristics (age, sex) and outpatient visits were included as control variables. Socioeconomic status revealed opposing utilization patterns: while individuals with higher education and income were more likely to consume non-prescribed medicines, the less educated were more likely to take prescribed medicines. Lower socioeconomic groups also showed a higher likelihood for prescribed polypharmacy. For the consumption of both medicine types, the main socioeconomic determinant was high income. In an additional analysis, lower socioeconomic groups were found to more likely report prescription purposes as the main reason for consulting a practitioner. These results point to different behavioural responses to ill health, not least determined by institutional incentives in the Austrian health care system. © The Author 2014.

The drug information literatures usually contains thousands of drugs, which much of them were rare or never prescribed by the physicians. It caused pharmacy students must learn thousands of drugs that will depleted resources and the study result was not effective. The aim of the study was to identify 200 items of drugs that mostly prescribed by the physicians in the pharmacies at Medan City. The study was a descriptive study that used a cross sectional survey methodology. The 200 items of drugs that mostly prescribed by the physician obtained from the pharmacies selected regarding to random sampling method. The study was conducted from August to September 2016. The 200 items of drugs that mostly prescribed by the physician resulted from 21.962 prescribed drugs item of 16.352 prescriptions of 100 pharmacies. The list revealed that the most prescribed drugs was amoxicilline (5.55 %), followed by dexamethasone (4.44%), mefenamic acid (3.73%), cetirizine (3.16%), and ciprofloxacine (2.97%). It shows that the antibiotic drug was the most prescribed drug by the physician in pharmacies at Medan City. Further studies are required to develop the study card from the list.

The objectives of this study were: 1) to establish criteria for evaluating handheld computerized prescribing systems; and 2) to evaluate out-of-box performance and features of a new, Palm Operating System (OS)-based, handheld, wireless wide area network (WWAN) prescribing system. The system consisted of a Palm Vx handheld organizer, a Novatel Minstrel V wireless modem, OmniSky wireless internet access and ePhysician ePad 1.1, the Palm OS electronic prescribing software program. A dermatologist familiar with healthcare information technology conducted an evaluation of the performance and features of a new, handheld, WWAN electronic prescribing system in an office practice during a three-month period in 2000. System performance, defined as transmission success rate, was determined from data collected during the three-month trial. Evaluation criteria consisted of an analysis of features found in electronic prescribing systems. All prescriptions written for all patients seen during a three-month period (August - November, 2000) were eligible for inclusion. Prescriptions written for patients who intended to fill them at pharmacies without known facsimile receiving capabilities were excluded from the study. The performance of the system was evaluated using data collected during the study. Criteria for evaluating features of electronic prescribing systems were developed and used to analyze the system employed in this study. During this three-month trial, 200 electronic prescriptions were generated for 132 patients included in the study. Of these prescriptions, 92.5 percent were successfully transmitted to pharmacies. Transmission failures resulted from incorrect facsimile numbers and non-functioning facsimile machines. Criteria established for evaluation of electronic prescribing systems included System (Hardware & Software), Costs, System Features, Printing & Transmission, Formulary & Insurance, Customization, Drug Safety and Security.

Dr. Fred Walter (Stony Brook University) has requested AAVSO observers' assistance in monitoring NR TrA (Nova TrA 2008) in support of upcoming XMM Newton observations. The XMM observations will take place 2017 March 13 06:21 through March 14 10:34 UT. Walter writes: "NR TrA (Nova TrA 2008) is a compact eclipsing system with a 5.5 hour period. It was a normal Fe II nova that, upon reaching quiescence, took on the appearance of a super-soft source in the optical high state, which suggests an extremely high mass accretion rate. The optical spectrum is dominated by hot permitted lines of O VI, N V, C IV, and He II. Some nova-like variables have similar spectra, though generally without the hot emission lines. Primary eclipse is broad - nearly 40% of the orbit - and deeper at shorter wavelengths, which suggests the eclipse of a hot accretion disk. Primary eclipse depth is about 1 mag at V. There appears to be a shallow secondary eclipse.The primary aim [of the XMM observations] is to detect and characterize the eclipse at X-ray and UV wavelengths. We will obtain low cadence BVRI/JHK observations with SMARTS/Andicam. We request AAVSO support to obtain continuous photometric time series simultaneous with the XMM observation. Any filters are acceptable, but standard Johnson B, V or Cousins R, I are preferred. Clear filters are acceptable. Time resolution better than 5 minutes and uncertainties (outside of eclipse) <0.02 mag are preferred. The best ephemeris I have is: minimum light at JD 55956.822 + 0.219109E. This is based on data from 2013-2015." Finder charts with sequence may be created using the AAVSO Variable Star Plotter (https://www.aavso.org/vsp).

Predicting prescribed magnification.

To determine the best method of estimating the optimum magnification needed by visually impaired patients. The magnification of low vision aids prescribed to 187 presbyopic visually impaired patients for reading newspapers or books was compared with logMAR distance and near acuity (at 25 cm) and magnification predicted by +4 D step near additions. Distance letter (r = 0.58) and near word visual acuity (r = 0.67) were strongly correlated to the prescribed magnification as were predictive formulae based on these measures. Prediction using the effect of proximal magnification resulted in a similar correlation (r = 0.67) and prediction was poorer in those who did not benefit from proximal magnification. The difference between prescribed and predicted magnification was found to be unrelated to the condition causing visual impairment (F = 2.57, p = 0.08), the central visual field status (F = 0.57, p = 0.57) and patient psychology (F = 0.44, p = 0.51), but was higher in those prescribed stand magnifiers than high near additions (F = 5.99, p < 0.01). The magnification necessary to perform normal visual tasks can be predicted in the majority of cases using visual acuity measures, although measuring the effect of proximal magnification demonstrates the effect of stronger glasses and identifies those in whom prescribed magnification is more difficult to predict.

Future perspectives on nonmedical prescribing

Many countries have implemented nonmedical prescribing (NMP) and many others are scoping prescribing practices with a view to developing NMP. This paper provides a future perspective on NMP in light of findings of an umbrella review of aspects of NMP. This is followed by coverage of the Scottish Government strategy of pharmacist prescribing and finally, consideration of two key challenges. The review identified seven systematic reviews of influences on prescribing decision-making, processes of prescribing, and barriers and facilitators to implementation. Decision making was reported as complex with many, and often conflicting, influences. Facilitators of NMP included perceived improved patient care and professional autonomy, while barriers included lack of defined roles and resource pressures. Three systematic reviews explored patient outcomes that were noted to be equivalent or better to physician prescribing. In particular, a Cochrane review of 46 studies of clinical, patient-reported, and resource-use outcomes of NMP compared with medical prescribing showed positive intervention-group effects. Despite positive findings, authors highlighted high bias, poor definition and description of ‘prescribing’ and the ‘prescribing process’ and difficulty in separating NMP effects from the contributions of other healthcare team members. While evidence of benefit and safety is essential to inform practice, for NMP to be implemented and sustained on a large scale, there needs to be clear commitment at the highest level. The approach being taken by the Scottish Government to pharmacist prescribing implementation may inform developments in other professions and countries. The vision is that by 2023, all pharmacists providing pharmaceutical care will be pharmacist-independent prescribers. There are, however, challenges to implementing NMP into working practice; two key challenges are the need for sustainable models of care and evaluation research. These challenges could

We determine episodic and high-quantity prescribers' contribution to opioid prescriptions and total morphine milligram equivalents in California, especially among individuals prescribed large amounts of opioids. This was a cross-sectional descriptive analysis of opioid prescribing patterns during an 8-year period using the de-identified Controlled Substance Utilization Review and Evaluation System (CURES) database, the California subsection of the prescription drug monitoring program. We took a 10% random sample of all patients and stratified them by the amount of prescription opioids obtained during their maximal 90-day period. We identified "episodic prescribers" as those whose prescribing pattern included short-acting opioids on greater than 95% of all prescriptions, fewer than or equal to 31 pills on 95% of all prescriptions, only 1 prescription in the database for greater than 90% of all patients to whom they gave opioids, fewer than 6 prescriptions in the database to greater than 99% of patients given opioids, and fewer than 540 prescriptions per year. We identified top 5% prescribers by their morphine milligram equivalents per day in the database. We examined the relationship between patient opioid prescriptions and provider type, with the primary analysis performed on the patient cohort who received only short-acting opioids in an attempt to avoid guideline-concordant palliative, oncologic, and addiction care, and a secondary analysis performed on all patients. Among patients with short-acting opioid only, episodic prescribers (14.6% of 173,000 prescribers) wrote at least one prescription to 25% of 2.7 million individuals but were responsible for less than 9% of the 10.5 million opioid prescriptions and less than 3% of the 3.9 billion morphine milligram equivalents in our sample. Among individuals with high morphine milligram equivalents use, episodic prescribers were responsible for 2.8% of prescriptions and 0.6% of total morphine milligram equivalents

OBJECTIVE: To describe benzodiazepine prescribing for elderly people living in the community in British Columbia, and to compare such prescribing with an indicator of current guidelines. DESIGN: Descriptive analysis of pharmacy billing data. SETTING: Province of British Columbia. PARTICIPANTS: All elderly persons (age 65 and older) dispensed benzodiazepines by community pharmacies in British Columbia during 1990. MAIN OUTCOME MEASURE: Potentially inappropriate prescriptions were defined by a maximum 2-month limit of 20 diazepam equivalents daily, as determined by the BC Drug Usage Review Program in consultation with experts in the field. Physicians' rates of potentially inappropriate prescribing were determined per 100 benzodiazepine prescriptions written. RESULTS: Almost 24% of elderly people in British Columbia were prescribed benzodiazepines at least once during 1990. Of these, 17.1% were given potentially inappropriate prescriptions. Physicians who prescribed benzodiazepines most frequently had the highest rates of potentially inappropriate prescriptions. CONCLUSION: Prescribing practice does not correspond with our indicator of current guidelines. PMID:7756916

In this work, we present transit timing variations detected for the exoplanet TrES-5b. To obtain the necessary amount of photometric data for this exoplanet, we have organized an international campaign to search for exoplanets based on the Transit Timing Variation method (TTV) and as a result of this we collected 30 new light curves, 15 light curves from the Exoplanet Transit Database (ETD) and 8 light curves from the literature for the timing analysis of the exoplanet TrES-5b. We have detected timing variations with a semi-amplitude of A ≈ 0.0016 days and a period of P ≈ 99 days. We carried out the N-body modeling based on the three-body problem. The detected perturbation of TrES-5b may be caused by a second exoplanet in the TrES-5 system. We have calculated the possible mass and resonance of the object: M ≈ 0.24MJup at a 1:2 Resonance.

The aim of this study was to examine prescribing trends for benzodiazepines and Z-drugs to General Medical Services (GMS) patients in Ireland. A repeated cross-sectional analysis of the national pharmacy claims database was conducted for GMS patients aged ≥16 years from 2005 to 2015. Prescribing rates per 1000 eligible GMS population were calculated with 95% confidence intervals (CIs). Negative binomial regression was used to determine longitudinal trends and compare prescribing rates across years, gender and age groups. Duration of supply and rates of concomitant benzodiazepine and Z-drug prescribing were determined. Age (16-44, 45-64, ≥65 years) and gender trends were investigated. Benzodiazepine prescribing rates decreased significantly from 225.92/1000 population (95% CI 224.94-226.89) in 2005 to 166.07/1000 population (95% CI 165.38-166.75) in 2015 (P < 0.0001). Z-drug prescribing rates increased significantly from 95.36/1000 population (95% CI 94.73-96.00) in 2005 to 109.11/1000 population (95% CI 108.56-109.67) in 2015 (P = 0.048). Approximately one-third of individuals dispensed either benzodiazepines or Z-drugs were receiving long-term prescriptions (>90 days). The proportion of those receiving >1 benzodiazepine and/or Z-drug concomitantly increased from 11.9% in 2005 to 15.3% in 2015. Benzodiazepine and Z-drug prescribing rates were highest for older women (≥65 years) throughout the study period. Benzodiazepine prescribing to the GMS population in Ireland decreased significantly from 2005 to 2015, and was coupled with significant increases in Z-drug prescribing. The study shows that benzodiazepine and Z-drug prescribing is common in this population, with high proportions of individuals receiving long-term prescriptions. Targeted interventions are needed to reduce potentially inappropriate long-term prescribing and use of these medications in Ireland. © 2018 The British Pharmacological Society.

Effects of an e-Prescribing interface redesign on rates of generic drug prescribing: exploiting default options.

Increasing the use of generic medications could help control medical costs. However, educational interventions have limited impact on prescriber behavior, and e-prescribing alerts are associated with high override rates and alert fatigue. Our objective was to evaluate the effect of a less intrusive intervention, a redesign of an e-prescribing interface that provides default options intended to "nudge" prescribers towards prescribing generic drugs. This retrospective cohort study in an academic ambulatory multispecialty practice assessed the effects of customizing an e-prescribing interface to substitute generic equivalents for brand-name medications during order entry and allow a one-click override to order the brand-name medication. Among drugs with generic equivalents, the proportion of generic drugs prescribed more than doubled after the interface redesign, rising abruptly from 39.7% to 95.9% (a 56.2% increase; 95% confidence interval, 56.0-56.4%; P < .001). Before the redesign, generic drug prescribing rates varied by therapeutic class, with rates as low as 8.6% for genitourinary products and 15.7% for neuromuscular drugs. After the redesign, generic drug prescribing rates for all but four therapeutic classes were above 90%: endocrine drugs, neuromuscular drugs, nutritional products, and miscellaneous products. Changing the default option in an e-prescribing interface in an ambulatory care setting was followed by large and sustained increases in the proportion of generic drugs prescribed at the practice. Default options in health information technology exert a powerful effect on user behavior, an effect that can be leveraged to optimize decision making. © The Author 2016.

2012-11-01

To establish the baseline prescribing error rate in a tertiary paediatric intensive care unit (PICU) and to determine the impact of a zero tolerance prescribing (ZTP) policy incorporating a dedicated prescribing area and daily feedback of prescribing errors. A prospective, non-blinded, observational study was undertaken in a 12-bed tertiary PICU over a period of 134 weeks. Baseline prescribing error data were collected on weekdays for all patients for a period of 32 weeks, following which the ZTP policy was introduced. Daily error feedback was introduced after a further 12 months. Errors were sub-classified as 'clinical', 'non-clinical' and 'infusion prescription' errors and the effects of interventions considered separately. The baseline combined prescribing error rate was 892 (95 % confidence interval (CI) 765-1,019) errors per 1,000 PICU occupied bed days (OBDs), comprising 25.6 % clinical, 44 % non-clinical and 30.4 % infusion prescription errors. The combined interventions of ZTP plus daily error feedback were associated with a reduction in the combined prescribing error rate to 447 (95 % CI 389-504) errors per 1,000 OBDs (p < 0.0001), an absolute risk reduction of 44.5 % (95 % CI 40.8-48.0 %). Introduction of the ZTP policy was associated with a significant decrease in clinical and infusion prescription errors, while the introduction of daily error feedback was associated with a significant reduction in non-clinical prescribing errors. The combined interventions of ZTP and daily error feedback were associated with a significant reduction in prescribing errors in the PICU, in line with Department of Health requirements of a 40 % reduction within 5 years.

TR-BREATH: Time-Reversal Breathing Rate Estimation and Detection.

PubMed

Chen, Chen; Han, Yi; Chen, Yan; Lai, Hung-Quoc; Zhang, Feng; Wang, Beibei; Liu, K J Ray

2018-03-01

In this paper, we introduce TR-BREATH, a time-reversal (TR)-based contact-free breathing monitoring system. It is capable of breathing detection and multiperson breathing rate estimation within a short period of time using off-the-shelf WiFi devices. The proposed system exploits the channel state information (CSI) to capture the miniature variations in the environment caused by breathing. To magnify the CSI variations, TR-BREATH projects CSIs into the TR resonating strength (TRRS) feature space and analyzes the TRRS by the Root-MUSIC and affinity propagation algorithms. Extensive experiment results indoor demonstrate a perfect detection rate of breathing. With only 10 s of measurement, a mean accuracy of can be obtained for single-person breathing rate estimation under the non-line-of-sight (NLOS) scenario. Furthermore, it achieves a mean accuracy of in breathing rate estimation for a dozen people under the line-of-sight scenario and a mean accuracy of in breathing rate estimation of nine people under the NLOS scenario, both with 63 s of measurement. Moreover, TR-BREATH can estimate the number of people with an error around 1. We also demonstrate that TR-BREATH is robust against packet loss and motions. With the prevailing of WiFi, TR-BREATH can be applied for in-home and real-time breathing monitoring.

Safe prescribing: a titanic challenge

Routledge, Philip A

2012-01-01

A range of health workforce strategies are needed to address health service demands in low-, middle- and high-income countries. Non-medical prescribing involves nurses, pharmacists, allied health professionals, and physician assistants substituting for doctors in a prescribing role, and this is one approach to improve access to medicines. To assess clinical, patient-reported, and resource use outcomes of non-medical prescribing for managing acute and chronic health conditions in primary and secondary care settings compared with medical prescribing (usual care). We searched databases including CENTRAL, MEDLINE, Embase, and five other databases on 19 July 2016. We also searched the grey literature and handsearched bibliographies of relevant papers and publications. Randomised controlled trials (RCTs), cluster-RCTs, controlled before-and-after (CBA) studies (with at least two intervention and two control sites) and interrupted time series analysis (with at least three observations before and after the intervention) comparing: 1. non-medical prescribing versus medical prescribing in acute care; 2. non-medical prescribing versus medical prescribing in chronic care; 3. non-medical prescribing versus medical prescribing in secondary care; 4 non-medical prescribing versus medical prescribing in primary care; 5. comparisons between different non-medical prescriber groups; and 6. non-medical healthcare providers with formal prescribing training versus those without formal prescribing training. We used standard methodological procedures expected by Cochrane. Two review authors independently reviewed studies for inclusion, extracted data, and assessed study quality with discrepancies resolved by discussion. Two review authors independently assessed risk of bias for the included studies according to EPOC criteria. We undertook meta-analyses using the fixed-effect model where studies were examining the same treatment effect and to account for small sample sizes. We compared

A Technological Innovation to Reduce Prescribing Errors Based on Implementation Intentions: The Acceptability and Feasibility of MyPrescribe

Background Although prescribing of medication in hospitals is rarely an error-free process, prescribers receive little feedback on their mistakes and ways to change future practices. Audit and feedback interventions may be an effective approach to modifying the clinical practice of health professionals, but these may pose logistical challenges when used in hospitals. Moreover, such interventions are often labor intensive. Consequently, there is a need to develop effective and innovative interventions to overcome these challenges and to improve the delivery of feedback on prescribing. Implementation intentions, which have been shown to be effective in changing behavior, link critical situations with an appropriate response; however, these have rarely been used in the context of improving prescribing practices. Objective Semistructured qualitative interviews were conducted to evaluate the acceptability and feasibility of providing feedback on prescribing errors via MyPrescribe, a mobile-compatible website informed by implementation intentions. Methods Data relating to 200 prescribing errors made by 52 junior doctors were collected by 11 hospital pharmacists. These errors were populated into MyPrescribe, where prescribers were able to construct their own personalized action plans. Qualitative interviews with a subsample of 15 junior doctors were used to explore issues regarding feasibility and acceptability of MyPrescribe and their experiences of using implementation intentions to construct prescribing action plans. Framework analysis was used to identify prominent themes, with findings mapped to the behavioral components of the COM-B model (capability, opportunity, motivation, and behavior) to inform the development of future interventions. Results MyPrescribe was perceived to be effective in providing opportunities for critical reflection on prescribing errors and to complement existing training (such as junior doctors’ e-portfolio).

Early experiences with E-prescribing.

PubMed

Halamka, John

2006-01-01

Most physicians understand that e-prescribing will reduce medical errors and will be perceived by patients as making the prescription process easier. However, they are skeptical about a number of things. They worry whether their office processes will be improved or streamlined; e-prescribing will interface seamlessly with their existing practice management software; training and support will be available; e-prescribing data will be seamlessly transferable to an electronic health record when they implement a more advanced clinical record system for their practice; and if they will achieve a return on investment. Early adopting clinicians in Massachusetts can convince the majority of clinicians to adopt e-prescribing by sharing their motivations for adopting e-prescribing, the challenges that they needed to overcome, the hardware and software requirements, and integration into their office workflow. Finally, interaction with the physicians and practice managers in the audience makes the adoption of e-prescribing seem both reasonable and exciting. Resources such as vendor lists, questions to ask, and hardware and software requirements also need to be readily available and in a form that non-technical staff can read and understand. Physicians who know the "why" would also like to know

Barriers to electronic prescribing: Nebraska pharmacists' perspective.

Electronic prescribing (e-prescribing) and its accompanying clinical decision support capabilities have been promoted as means for reducing medication errors and improving efficiency. The objectives of this study were to identify the barriers to adoption of e-prescribing among nonparticipating Nebraska pharmacies and to describe how the lack of pharmacy participation impacts the ability of physicians to meet meaningful use criteria. We interviewed pharmacists and/or managers from nonparticipating pharmacies to determine barriers to the adoption of e-prescribing. We used open-ended questions and a structured questionnaire to capture participants' responses. Of the 23 participants, 10 (43%) reported plans to implement e-prescribing sometime in the future but delayed participation due to transaction fees and maintenance costs, as well as lack of demand from customers and prescribers to implement e-prescribing. Nine participants (39%) reported no intention to e-prescribe in the future, citing start-up costs for implementing e-prescribing, transaction fees and maintenance costs, happiness with the current system, and lack of understanding about e-prescribing's benefits and how to implement e-prescribing. The barriers to e-prescribing identified by both late adopters and those not willing to accept e-prescriptions were similar and were mainly initial costs and transaction fees associated with each new prescription. For some rural pharmacies, not participating in e-prescribing may be a rational business decision. To increase participation, waiving or reimbursing transaction fees, based on demographic or financial characteristics of the pharmacy, may be warranted. © 2012 National Rural Health Association.

High-efficiency L-band T/R Module: Development Results

NASA Technical Reports Server (NTRS)

Edelstein, Wendy N.; Andricos, Constantine; Wang, Feiyu; Rutled, David B.

2005-01-01

Future interferometric synthetic aperture radar (InSAR) systems require electronically scanned phased-array antennas, where the transmit/receive (T/R) module is a key component. The T/R module efficiency is a critical figure of merit and has direct implications on the power dissipation and power generation requirements of the system. Significant improvements in the efficiency of the T/R module will make SAR missions more feasible and affordable. The results of two high-efficiency T/R modules are presented, each based on different power amplifier technologies. One module uses a 30W GaAs Class-AlB power amplifier and the second module uses a 70W LD-MOS Class-ElF power amplifier, where both modules use a common low power section. Each module operates over an 80MHz bandwidth at L-band (1.2GHz) with an overall module efficiency greater than 58%. We will present the results of these two T/R modules that have been designed, built and tested.

Prescribing practices amid the OxyContin crisis: examining the effect of print media coverage on opioid prescribing among physicians.

Borwein, Alexandra; Kephart, George; Whelan, Emma; Asbridge, Mark

2013-12-01

The pain medication OxyContin (hereafter referred to as oxycodone extended release) has been the subject of sustained, and largely negative, media attention in recent years. We sought to determine whether media coverage of oxycodone extended release in North American newspapers has led to changes in prescribing of the drug in Nova Scotia, Canada. An interrupted time-series design examined the effect of media attention on physicians' monthly prescribing of opioids. The outcome measures were, for each physician, the monthly proportions of all opioids prescribed and the proportion of strong opioids prescribed that were for oxycodone extended release. The exposure of interest was media attention defined as the number of articles published each month in 27 North American newspapers. Variations in media effects by provider characteristics (specialty, prescribing volume, and region) were assessed. Within-provider changes in the prescribing of oxycodone extended release in Nova Scotia were observed, and they followed changes in media coverage. Oxycodone extended release prescribing rose steadily prior to receiving media attention. Following peak media attention in the United States, the prescribing of oxycodone extended release slowed. Likewise, following peak coverage in Canadian newspapers, the prescribing of oxycodone extended release declined. These patterns were observed across prescriber specialties and by prescriber volume, though the magnitude of change in prescribing varied. This study demonstrates that print media reporting of oxycodone extended release in North American newspapers, and its continued portrayal as a social problem, coincided with reductions in the prescribing of oxycodone extended release by physicians in Nova Scotia.

Prescribing Errors Involving Medication Dosage Forms

PubMed Central

Lesar, Timothy S

2002-01-01

CONTEXT Prescribing errors involving medication dose formulations have been reported to occur frequently in hospitals. No systematic evaluations of the characteristics of errors related to medication dosage formulation have been performed. OBJECTIVE To quantify the characteristics, frequency, and potential adverse patient effects of prescribing errors involving medication dosage forms . DESIGN Evaluation of all detected medication prescribing errors involving or related to medication dosage forms in a 631-bed tertiary care teaching hospital. MAIN OUTCOME MEASURES Type, frequency, and potential for adverse effects of prescribing errors involving or related to medication dosage forms. RESULTS A total of 1,115 clinically significant prescribing errors involving medication dosage forms were detected during the 60-month study period. The annual number of detected errors increased throughout the study period. Detailed analysis of the 402 errors detected during the last 16 months of the study demonstrated the most common errors to be: failure to specify controlled release formulation (total of 280 cases; 69.7%) both when prescribing using the brand name (148 cases; 36.8%) and when prescribing using the generic name (132 cases; 32.8%); and prescribing controlled delivery formulations to be administered per tube (48 cases; 11.9%). The potential for adverse patient outcome was rated as potentially “fatal or severe” in 3 cases (0.7%), and “serious” in 49 cases (12.2%). Errors most commonly involved cardiovascular agents (208 cases; 51.7%). CONCLUSIONS Hospitalized patients are at risk for adverse outcomes due to prescribing errors related to inappropriate use of medication dosage forms. This information should be considered in the development of strategies to prevent adverse patient outcomes resulting from such errors. PMID:12213138

Nurse prescribing: reflections on safety in practice.

PubMed

Bradley, Eleanor; Hynam, Brian; Nolan, Peter

2007-08-01

This qualitative study explores how recently qualified nurse prescribers describe, and rate, the safety of their prescribing. Internationally, the costs of drug errors are enormous and they can have serious implications for staff and patients. Nurses are now undertaking extended prescribing practice throughout the UK. Nurse prescribers work across different work settings and although safe prescribing is a priority in all of them, it is essential to ascertain the conditions that foster the highest levels of safety and how nurses can be supported in practice. Thirty-one nurses form the West Midlands area of England agreed to participate in an in-depth interview which sought to elicit their responses to various aspects of their prescribing work. They came from a variety of specialities and from hospital, community and general practice backgrounds. On completion of their training nurses were acutely aware of the responsibility that prescribing imposed on them. Although this awareness was thought to encourage caution and safety, it may also account for the fact that 26% of the nurses (n=8) had not prescribed since qualifying. Nurses felt that the multidisciplinary team had a vital role to play in supporting their prescribing practice as did collaborative working. It is concluded that those working in specialty areas that are less well-defined in terms of scope of practice (e.g. older adult nursing and learning disability) would benefit in particular from ongoing mentoring relationships with experienced prescribers and the development of individual formularies.

Implementing nurse prescribing: a case study in diabetes.

PubMed

Stenner, Karen; Carey, Nicola; Courtenay, Molly

2010-03-01

This paper is a report of a study exploring the views of nurses and team members on the implementation of nurse prescribing in diabetes services. Nurse prescribing is adopted as a means of improving service efficiency, particularly where demand outstretches resources. Although factors that support nurse prescribing have been identified, it is not known how these function within specific contexts. This is important as its uptake and use varies according to mode of prescribing and area of practice. A case study was undertaken in nine practice settings across England where nurses prescribed medicines for patients with diabetes. Thematic analysis was conducted on qualitative data from 31 semi-structured interviews undertaken between 2007 and 2008. Participants were qualified nurse prescribers, administrative staff, physicians and non-nurse prescribers. Nurses prescribed more often following the expansion of nurse independent prescribing rights in 2006. Initial implementation problems had been resolved and few current problems were reported. As nurses' roles were well-established, no major alterations to service provision were required to implement nurse prescribing. Access to formal and informal resources for support and training were available. Participants were accepting and supportive of this initiative to improve the efficiency of diabetes services. The main factors that promoted implementation of nurse prescribing in this setting were the ability to prescribe independently, acceptance of the prescribing role, good working relationships between doctors and nurses, and sound organizational and interpersonal support. The history of established nursing roles in diabetes care, and increasing service demand, meant that these diabetes services were primed to assimilate nurse prescribing.

Alprazolam prescribing in Tasmania: a two-fold intervention designed to reduce inappropriate prescribing and concomitant opiate prescription.

PubMed

Hooper, Stuart; Bruno, Raimondo; Sharpe, Mary; Tahmindjis, Alex

2009-08-01

The population rate of alprazolam prescribing in Tasmania has been more than double that of national rates. Serious adverse events have been observed through co-administration of opioid medications with alprazolam. A two-fold intervention, comprising GP education coupled with changes to prescribing regulations, was designed with the intention to decrease inappropriate prescribing of alprazolam and thereby reduce adverse outcomes. The aim of this study was to assess the impact of the intervention on prescribing rates. We measured the number of alprazolam prescriptions for the years prior to and the year following the intervention. Health Insurance Commission data were utilized to enable comparison of subsidized prescription rates for alprazolam in Tasmania, and compared with national data. Participants were registered medical practitioners in Tasmania who were potential prescribers of alprazolam. The interventions were three GP Education Meetings during June 2007, one in each of the major regions of Tasmania, regarding evidence-based interventions for panic disorder. Changes to regulatory procedures to minimize co-prescription of alprazolam with opioids was implemented in September 2007. A reduction in alprazolam prescribing in Tasmania occurred after the interventions. Education can be an effective strategy to influence prescribing behaviour of doctors. It is likely that this effect can be augmented by adoption of more stringent regulatory requirements.

Psychiatric Prescribers' Experiences With Doctor Shoppers.

PubMed

Worley, Julie; Johnson, Mary; Karnik, Niranjan

2015-01-01

Doctor shopping is a primary method of prescription medication diversion. After opioids, benzodiazepines and stimulants are the next most common prescription medications used nonmedically. Studies have shown that patients who engage in doctor shopping find it fun, exciting, and easy to do. There is a lack of research on the prescriber's perspective on the phenomenon of doctor shopping. This study investigates the experiences of prescribers in psychiatry with patients who engage in doctor shopping. Fifteen prescribers including psychiatrists and psychiatric nurse practitioners working in outpatient psychiatry were interviewed to elicit detailed information about their experiences with patients who engage in doctor shopping. Themes found throughout the interview were that psychiatric prescribers' experience with patients who engage in doctor shopping includes (a) detecting red flags, (b) negative emotional responding, (c) addressing the patient and the problem, and (d) inconsistently implementing precautions. When red flags were detected when prescribing controlled drugs, prescribers in psychiatry experienced both their own negative emotional responses such as disappointment and resentment as well as the negative emotions of the patients such as anger and other extreme emotional responses. Psychiatric prescribers responded to patient's doctor shopping in a variety of ways such as changing their practice, discharging the patients or taking steps to not accept certain patients identified as being at risk for doctor shopping, as well as by talking to the patient and trying to offer them help. Despite experiencing doctor shopping, the prescribers inconsistently implemented precautionary measures such as checking prescription drug monitoring programs. © The Author(s) 2015.

A model of methods for influencing prescribing: Part I. A review of prescribing models, persuasion theories, and administrative and educational methods.

PubMed

Raisch, D W

1990-04-01

The purpose of this literature review is to develop a model of methods to be used to influence prescribing. Four bodies of literature were identified as being important for developing the model: (1) Theoretical prescribing models furnish information concerning factors that affect prescribing and how prescribing decisions are made. (2) Theories of persuasion provide insight into important components of educational communications. (3) Research articles of programs to improve prescribing identify types of programs that have been found to be successful. (4) Theories of human inference describe how judgments are formulated and identify errors in judgment that can play a role in prescribing. This review is presented in two parts. This article reviews prescribing models, theories of persuasion, studies of administrative programs to control prescribing, and sub-optimally designed studies of educational efforts to influence drug prescribing.

Automation bias in electronic prescribing.

Clinical decision support (CDS) in e-prescribing can improve safety by alerting potential errors, but introduces new sources of risk. Automation bias (AB) occurs when users over-rely on CDS, reducing vigilance in information seeking and processing. Evidence of AB has been found in other clinical tasks, but has not yet been tested with e-prescribing. This study tests for the presence of AB in e-prescribing and the impact of task complexity and interruptions on AB. One hundred and twenty students in the final two years of a medical degree prescribed medicines for nine clinical scenarios using a simulated e-prescribing system. Quality of CDS (correct, incorrect and no CDS) and task complexity (low, low + interruption and high) were varied between conditions. Omission errors (failure to detect prescribing errors) and commission errors (acceptance of false positive alerts) were measured. Compared to scenarios with no CDS, correct CDS reduced omission errors by 38.3% (p < .0001, n = 120), 46.6% (p < .0001, n = 70), and 39.2% (p < .0001, n = 120) for low, low + interrupt and high complexity scenarios respectively. Incorrect CDS increased omission errors by 33.3% (p < .0001, n = 120), 24.5% (p < .009, n = 82), and 26.7% (p < .0001, n = 120). Participants made commission errors, 65.8% (p < .0001, n = 120), 53.5% (p < .0001, n = 82), and 51.7% (p < .0001, n = 120). Task complexity and interruptions had no impact on AB. This study found evidence of AB omission and commission errors in e-prescribing. Verification of CDS alerts is key to avoiding AB errors. However, interventions focused on this have had limited success to date. Clinicians should remain vigilant to the risks of CDS failures and verify CDS.

False responses of Renilla luciferase reporter control to nuclear receptor TR4.

2017-06-01

Renilla luciferase reporter is a widely used internal control in dual luciferase reporter assay system, where its transcription is driven by a constitutively active promoter. However, the authenticity of the Renilla luciferase response in some experimental settings has recently been questioned. Testicular receptor 4 (TR4, also known as NR2C2) belongs to the subfamily 2 of nuclear receptors. TR4 binds to a direct repeat regulatory element in the promoter of a variety of target genes and plays a key role in tumorigenesis, lipoprotein regulation, and central nervous system development. In our experimental system using murine pituitary corticotroph tumor AtT20 cells to investigate TR4 actions on POMC transcription, we found that overexpression of TR4 resulted in reduced Renilla luciferase expression whereas knockdown TR4 increased Renilla luciferase expression. The TR4 inhibitory effect was mediated by the TR4 DNA-binding domain and behaved similarly to the GR and its agonist, Dexamethasone. We further demonstrated that the chimeric intron, commonly present in various Renilla plasmid backbones such as pRL-Null, pRL-SV40, and pRL-TK, was responsible for TR4's inhibitory effect. The results suggest that an intron-free Renilla luciferase reporter may provide a satisfactory internal control for TR4 at certain dose range. Our findings advocate caution on the use of Renilla luciferase as an internal control in TR4-directed studies to avoid misleading data interpretation.

Massive stars near Eta Carinae - The stellar content of TR 14 and TR 16

NASA Astrophysics Data System (ADS)

1993-03-01

The stellar content of the region around the star Eta Carinae, including the two Galactic OB clusters Tr 14 and Tr 16, are investigated using CCD photometry and spectroscopy. A physical H-R diagram is constructed which shows that several stars are located above the 85-solar mass track, as well as that the location of Eta Carinae is consistent with the interpretation that it is a very massive star undergoing a normal evolutionary stage. The W-R star which is present in this region is lower in luminosity than expected. The initial mass function derived, which is similar to two other young Galactic clusters studied, has a slope flatter than some regions in the Magellanic Clouds that are also rich in massive stars. The most luminous and massive stars near Eta Carinae are not significantly more than the most luminous and massive stars found in the Magellanic Clouds.

The role of prescribed burn associations in the application of prescribed fires in rangeland ecosystems.

Risk and liability concerns regarding fire affect people's attitudes toward fire and have led to human-induced alterations of fire regimes. This has, in turn, contributed to brush encroachment and degradation of many grasslands and savannas. Efforts to successfully restore such degraded ecosystems at the landscape scale in regions of the United States with high proportions of private lands require the reintroduction of fire. Prescribed Burn Associations (PBA) provide training, equipment, and labor to apply fire safely, facilitating the application of this rangeland management tool and thereby reducing the associated risk. PBAs help build networks and social capital among landowners who are interested in using fire. They can also change attitudes toward fire and enhance the social acceptability of using prescribed fire as a management practice. PBAs are an effective mechanism for promoting the widespread use of prescribed fire to restore and maintain the biophysical integrity of grasslands and savannas at the landscape scale. We report findings of a project aimed at determining the human dimensions of using prescribed fire to control woody plant encroachment in three different eco-regions of Texas. Specifically, we examine membership in PBAs as it relates to land manager decisions regarding the use of prescribed fire. Perceived risk has previously been identified as a key factor inhibiting the use of prescribed fire by landowners. Our results show that perceived constraints, due to lack of skill, knowledge, and access to equipment and membership in a PBAs are more important factors than risk perceptions in affecting landowner decisions about the use of fire. This emphasizes the potential for PBAs to reduce risk perceptions regarding the application of prescribed fire and, therefore, their importance for restoring brush-encroached grasslands and savannas.

Except in remote areas, most prescribed fires will have some effect on members of the public. It is therefore important for land managers to work with the public before, during, and after a prescribed burn. To do this effectively, managers need to have an accurate idea of what people do and do not think about prescribed fire and they need to understand what shapes...

The incorporation of medication indications into the prescribing process to improve patient safety is discussed. Currently, most prescriptions lack a key piece of information needed for safe medication use: the patient-specific drug indication. Integrating indications could pave the way for safer prescribing in multiple ways, including avoiding look-alike/sound-alike errors, facilitating selection of drugs of choice, aiding in communication among the healthcare team, bolstering patient understanding and adherence, and organizing medication lists to facilitate medication reconciliation. Although strongly supported by pharmacists, multiple prior attempts to encourage prescribers to include the indication on prescriptions have not been successful. We convened 6 expert panels to consult high-level stakeholders on system design considerations and requirements necessary for building and implementing an indications-based computerized prescriber order-entry (CPOE) system. We summarize our findings from the 6 expert stakeholder panels, including rationale, literature findings, potential benefits, and challenges of incorporating indications into the prescribing process. Based on this stakeholder input, design requirements for a new CPOE interface and workflow have been identified. The emergence of universal electronic prescribing and content knowledge vendors has laid the groundwork for incorporating indications into the CPOE prescribing process. As medication prescribing moves in the direction of inclusion of the indication, it is imperative to design CPOE systems to efficiently and effectively incorporate indications into prescriber workflows and optimize ways this can best be accomplished.

Mental health pharmacists as interim prescribers

PubMed Central

2017-01-01

Introduction: Turnover leading to fluctuations in prescriber availability presents many challenges, most notably in access to and continuity of care. In 2015, the Veterans Affairs Eastern Colorado Healthcare System (VA ECHCS) experienced a period of significant mental health prescriber turnover leading to patient utilization of psychiatric emergency services (PES) for nonemergent medication management. The resulting increase in volume placed excessive stress on PES prescribers. Mental health pharmacists have opportunities to provide interim medication management while patients are between prescribers. Methods: This study was a retrospective, cohort study of patients unassigned to an outpatient mental health prescriber due to prescriber turnover, receiving care at VA ECHCS between October 1, 2015, and February 28, 2016. The primary outcome was the number of pharmacist interventions performed. Secondary outcomes characterize the interventions performed and describe the change in the mean monthly volume of patients presenting to PES. Results: In this veteran population, 152 interventions were performed in 81 unique patients. The most common intervention was prescription renewals (80%). Interventions most commonly involved antidepressants (28%), antipsychotics (10%), and mood stabilizers (10%). Before initiation of the clinic, Denver VA PES experienced a mean of 300 monthly visits. After clinic implementation, PES visits decreased significantly to a mean of 237 visits per month (P = .041). Discussion: The pharmacist interim prescriber clinic was associated with a significant decrease in mean number of patients seen per month in PES. The success of the clinic also contributed to interest by the mental health service to expand clinical pharmacy services.

Overprescribing of oxycodone is a contributor to the epidemic of prescription opioid misuse and deaths. Practice models to optimize oxycodone prescribing and supply need to be evaluated. We explored the impact of pharmacist-assisted discharge prescribing and medication review on oxycodone prescribing and supply for patients discharged from surgical wards. A retrospective audit was conducted on two surgical inpatient wards following a 16-week prospective pre- and post-intervention study. During the pre-intervention period, discharge prescriptions were prepared by hospital doctors and then reviewed by a ward pharmacist (WP) before being dispensed. Post-intervention, prescriptions were prepared by a project pharmacist in consultation with hospital doctors and then reviewed by a WP and dispensed. Proportion of patients who were prescribed, and proportion supplied, oxycodone on discharge; Median amount (milligrams) of oxycodone prescribed and supplied, for patients who were prescribed and supplied at least one oxycodone-containing preparation, respectively. A total of 320 and 341 patients were evaluated pre- and post-intervention, respectively. Pre-intervention, 75.6% of patients were prescribed oxycodone; after WP review, 60.3% were supplied oxycodone (P<.01); the median amount both prescribed and supplied was 100 milligrams/patient. Post-intervention, 68.6% of patients were prescribed oxycodone; after WP review, 57.8% were supplied oxycodone (P<.01); median amount prescribed and supplied was 50 milligrams/patient (difference in amount prescribed and supplied: 50 milligrams, P<.01). WP review of doctor-prepared prescriptions reduced the proportion of patients who were supplied oxycodone but not the amount supplied/patient. Having a pharmacist assist with prescribing reduced the amount of oxycodone supplied. © 2017 John Wiley & Sons Ltd.

The number of nurses able to independently prescribe medicines in England has risen steadily in recent years. To evaluate the adequacy of nurses' educational preparation for independent prescribing and to describe nurses' experiences of their continuing professional development as prescribers in practice. Postal questionnaire survey. Random sample of 246 nurses registered as nurse independent prescribers with the Nursing and Midwifery Council. The majority of nurses considered that the initial taught course element of their education programme met their needs, either to some extent (61% 151/246), or completely (22% 54/246). Most nurses (77% 190/246) received the specified 12 days support from their supervising medical practitioner and most were satisfied and positive about this experience. Nearly all of the nurses (>95%) reported that they were able to maintain a range of specified prescribing competencies in practice. Two thirds (62% 152/246) of the sample reported that they were receiving support/supervision for prescribing. Ninety five per cent (233/246) of the sample also reported that they engaged in self-directed informal continuing professional development, but only half of the sample had experience of formally provided professional development opportunities. Approximately half (52% 127/246) of the sample identified needs for continuing professional development. This first national survey of the education and professional development experiences of nurse independent prescribers in England provides evidence which highlights areas in which national policy is working well, and also points up issues which may need addressing as the roll out of nurse prescribing continues. The study also highlights characteristics and issues that health care policy makers and nurse educationalists internationally may wish to consider in developing and refining their own nurse prescriber education programmes.

2013-03-01

Antimicrobial use is known to select for the emergence of resistant strains of bacteria; therefore prudent use in both human and veterinary medicine is essential to preserve their efficacy. To characterise antimicrobial prescribing patterns in UK equine practice and evaluate factors associated with prescribing. A postal questionnaire including 4 clinical scenarios was sent to 740 veterinary surgeons that treat horses. Data were collected on the clinician, their practice and sources of information regarding antimicrobials and their use. Multivariable logistic regression analysis was used to ascertain factors associated with 5 outcomes; prescribing off-licence drugs; prescribing at incorrect doses; prescribing 3rd or 4th generation cephalosporins; prescribing fluoroquinolones and prescribing potentiated sulphonamides. Questionnaires were completed by 38% of veterinary surgeons who were sent questionnaires. Less than 1% of practices had antimicrobial use guidelines. Trimethoprim-sulphonamides were most commonly prescribed in each clinical scenario. Eleven percent of prescriptions were for antimicrobial drugs not licensed for use in horses in the UK. Five percent of prescriptions for licensed antimicrobials were under the recommended dose rate and 56% over the recommended dose rate. Fluoroquinolones and 3rd and 4th generation cephalosporins accounted for 1 and 3% of prescriptions, respectively. Veterinary surgeons working at referral practices were more likely to prescribe 3rd and 4th generation cephalosporins and fluoroquinolones and off-licence antimicrobials whereas those working in first-opinion practices were more likely to prescribe potentiated sulphonamides. Sources of information regarding antimicrobials also had an effect on prescribing. Prescription of antimicrobials at inappropriate doses was common even when provided with the weight of the animal. It is uncommon for UK equine veterinary practices to have guidelines for antimicrobial use. The introduction of

2008-01-01

The aim of this study was to identify the factors that influence prescribing of new drugs among general practitioners, endocrinologists and psychiatrists. Four focus groups were conducted with GPs, endocrinologists and psychiatrists on sources of awareness and influences on prescribing of new drugs. Pharmaceutical companies were the most important source for becoming aware of new drugs. There were many influences on the decision to prescribe a new drug, the most important being efficacy, safety, cost and advantage over existing therapies. Endocrinologists placed greater emphasis on evidence from clinical trials and scientific conferences, and psychiatrists and GPs placed more weight on pharmaceutical representatives, colleagues and specialists. New drug prescribing occurs in a complex environment with many influences. Effective interventions to promote rational, safe and effective prescribing of new drugs will need to be cognisant of these factors.

Physician prescribing behavior and its impact on patient-level outcomes.

2011-12-01

Concerns over rising drug costs, pharmaceutical advertising, and potential conflicts of interest have focused attention on physician prescribing behavior. We examine how broadly physicians prescribe within the 10 most prevalent therapeutic classes, the factors affecting their choices, and the impact of their prescribing behavior on patient-level outcomes. Retrospective study from 2005 to 2007 examining prescribers with at least 5 initial prescriptions within a class from 2005 to 2007. Medical and pharmacy claims are linked to prescriber information from 146 different health plans, reflecting 1975 to 8923 unique providers per drug class. Primary outcomes are the number of distinct drugs in a class initially prescribed by a physician over 1- and 3-year periods, medication possession ratio, and out-of-pocket costs. In 8 of 10 therapeutic classes, the median physician prescribes at least 3 different drugs and fewer than 1 in 6 physicians prescribe only brand drugs. Physicians prescribing only 1 or 2 drugs in a class are more likely to prescribe the most advertised drug. Physicians who prescribe fewer drugs are less likely to see patients with other comorbid conditions and varied formulary designs. Prescribing fewer drugs is associated with lower rates of medication adherence and higher out-ofpocket costs for drugs, but the effects are small and inconsistent across classes. Physicians prescribe more broadly than commonly perceived. Though narrow prescribers are more likely to prescribe highly advertised drugs, few physicians prescribe these drugs exclusively. Narrow prescribing has modest effects on medication adherence and out-of-pocket costs in some classes.

2009-12-01

To assess the types and frequency of antibiotic prescriptions by Belgian dentists, the indications for antibiotic prescription, and dentists' knowledge about recommended practice in antibiotic use. In this cross-sectional survey, dental practitioners were asked to record information about all antibiotics prescribed to their patients during a 2-week period. The dental practitioners were also asked to complete a self-administered questionnaire regarding demographic data, prescribing practices, and knowledge about antibiotic use. A random sample of 268 Belgian dentists participated in the survey. During the 2-week period, 24 421 patient encounters were recorded; 1033 patients were prescribed an antibiotic (4.2%). The median number of prescriptions per dentist for the 2 weeks was 3. Broad spectrum antibiotics were most commonly prescribed: 82% of all prescriptions were for amoxycillin, amoxycillin-clavulanic acid and clindamycin. Antibiotics were often prescribed in the absence of fever (92.2%) and without any local treatment (54.2%). The most frequent diagnosis for which antibiotics were prescribed was periapical abscess (51.9%). Antibiotics were prescribed to 63.3% of patients with periapical abscess and 4.3% of patients with pulpitis. Patterns of prescriptions were confirmed by the data from the self-reported practice. Discrepancies between observed and recommended practice support the need for educational initiatives to promote rational use of antibiotics in dentistry in Belgium.

Pharmacists in Canadian provinces are at different stages of applying prescribing legislation into practice. The purpose of this environmental scan was to examine differences in legislation, remuneration, professional uptake, continuing education requirements and continuing education resources relating to pharmacist prescribing for ambulatory ailments, with a focus on continuing education. Data were collected between May and December 2016 using websites and communication with provincial professional regulatory bodies, advocacy bodies, drug coverage programs and other organizations that offer continuing education for pharmacists. Training requirements to prescribe for ambulatory ailments vary provincially, including no training requirements, online tutorials and a comprehensive application process. Government-funded remuneration for prescribing services is absent in most provinces. Pharmacist uptake of the training required to obtain prescribing authority ranges from 30% to 100% of pharmacists. Continuing education programs on the topic of prescribing across the country include online courses, in-person courses, webinars, panel discussions and preparation courses. Many aspects of pharmacist prescribing for ambulatory ailments, including the style and content of continuing education resources, vary from province to province. Further research on this topic would help to determine the effect of these differences on the success of incorporating pharmacist prescribing into practice.

A systematic review of educational interventions to change behaviour of prescribers in hospital settings, with a particular emphasis on new prescribers

PubMed Central

Brennan, Nicola; Mattick, Karen

2013-01-01

Aims Prescribing is a complex task and a high risk area of clinical practice. Poor prescribing occurs across staff grades and settings but new prescribers are attributed much of the blame. New prescribers may not be confident or even competent to prescribe and probably have different support and development needs than their more experienced colleagues. Unfortunately, little is known about what interventions are effective in this group. Previous systematic reviews have not distinguished between different grades of staff, have been narrow in scope and are now out of date. Therefore, to inform the design of educational interventions to change prescribing behaviour, particularly that of new prescibers, we conducted a systematic review of existing hospital-based interventions. Methods Embase, Medline, SIGLE, Cinahl and PsychINFO were searched for relevant studies published 1994–2010. Studies describing interventions to change the behaviour of prescribers in hospital settings were included, with an emphasis on new prescibers. The bibliographies of included papers were also searched for relevant studies. Interventions and effectiveness were classified using existing frameworks and the quality of studies was assessed using a validated instrument. Results Sixty-four studies were included in the review. Only 13% of interventions specifically targeted new prescribers. Most interventions (72%) were deemed effective in changing behaviour but no particular type stood out as most effective. Conclusion Very few studies have tailored educational interventions to meet needs of new prescribers, or distinguished between new and experienced prescribers. Educational development and research will be required to improve this important aspect of early clinical practice. PMID:22831632

Resistance to triazoles in Aspergillus fumigatus has been reported in azole-naive patients in Europe, Asia, Australia and North America. This resistance has been linked to fungicide-driven mutations in the cyp51A gene and its promoter region. We investigated the presence of environmental azole-resistant A. fumigatus strains related to the use of azole fungicides in Colombia. Soil samples were collected from flower beds, flower fields and public gardens from the outskirts, suburbs and city centre of Bogotá. Out of the 86 soil samples taken, 17 (19.8%) grew A. fumigatus of whom eight (9.3%) contained 40 strains able to grow on azole-containing itraconazole and/or voriconazole supplemented media. All but one triazole-resistant strains were isolated from soil samples collected from flower fields and flower beds (39/40). Importantly, the majority had the TR46/Y121F/T289A, TR34/L98H, and TR53 molecular resistance mechanisms and one azole resistant strain had a wild-type cyp51A gene. Soil samples from flower fields and beds contained 4 azole fungicides (penconazole, difenoconazole, tetraconazole and tebuconazole) above the limit of detection. Our findings underline the need for extensive investigations to determine azole-resistant A. fumigatus prevalence in both clinical and environmental samples in other regions of Latin America.

We generated TR4 knockout mice and compared skeletal development with their wild type littermates. Primary bone marrow cells were cultured and we assayed bone differentiation by alkaline phosphatase and alizarin red staining. Primary calvaria were cultured and osteoblastic marker genes were detected by quantitative PCR. Luciferase reporter assays, chromatin immunoprecipitation (ChIP) assays, and electrophoretic mobility shift assays (EMSA) were performed to demonstrate TR4 can directly regulate bone differentiation marker osteocalcin. We first found mice lacking TR4 might develop osteoporosis. We then found that osteoblast progenitor cells isolated from bone marrow of TR4 knockout mice displayed reduced osteoblast differentiation capacity and calcification. Osteoblast primary cultures from TR4 knockout mice calvaria also showed higher proliferation rates indicating lower osteoblast differentiation ability in mice after loss of TR4. Mechanism dissection found the expression of osteoblast markers genes, such as ALP, type I collagen alpha 1, osteocalcin, PTH, and PTHR was dramatically reduced in osteoblasts from TR4 knockout mice as compared to those from TR4 wild type mice. In vitro cell line studies with luciferase reporter assay, ChIP assay, and EMSA further demonstrated TR4 could bind directly to the promoter region of osteocalcin gene and induce its gene expression at the transcriptional level in a dose dependent manner. Together, these results demonstrate TR4 may function as a novel transcriptional factor to play pathophysiological roles in maintaining normal osteoblast activity during the bone development and remodeling, and disruption of TR4 function may result in multiple skeletal abnormalities.

Drug advertising and prescribing

A study of the amount of drug advertisements received by general practitioners and the amount of the drugs practitioners prescribed showed a strong correlation of 0·80. Analysis suggests that a straight line graphic relationship provides the best fit for the results obtained. Further analysis of the quantity of advertising in relation to the amount of prescribing revealed two groups of drugs: those which were relatively more and those which were relatively less often advertised in proportion to the number of prescriptions issued for them.

The estimated incidence of mitochondrial diseases in humans is approximately 1:5000 to 1:10,000, whereas the molecular mechanisms for more than 50% of human mitochondrial disease cases still remain unclear. Here we report that mice lacking testicular nuclear receptor 4 (TR4−/−) suffered mitochondrial myopathy, and histological examination of TR4−/− soleus muscle revealed abnormal mitochondrial accumulation. In addition, increased serum lactate levels, decreased mitochondrial ATP production, and decreased electron transport chain complex I activity were found in TR4−/− mice. Restoration of TR4 into TR4−/− myoblasts rescued mitochondrial ATP generation capacity and complex I activity. Further real-time PCR quantification and promoter studies found TR4 could modulate complex I activity via transcriptionally regulating the complex I assembly factor NDUFAF1, and restoration of NDUFAF1 level in TR4−/− myoblasts increased mitochondrial ATP generation capacity and complex I activity. Together, these results suggest that TR4 plays vital roles in mitochondrial function, which may help us to better understand the pathogenesis of mitochondrial myopathy, and targeting TR4 via its ligands/activators may allow us to develop better therapeutic approaches.

District nurses' prescribing practice and its link to structural conditions.

PubMed

Blanck, Susanne; Engström, Maria

2015-10-01

To describe district nurses' (DNs') prescribing practice and examine associations between DNs' self-reported prescribing frequency, opinions about prescribing, and structural conditions/empowerment. A cross-sectional and correlational design was employed. Data were collected during 2012 using questionnaires and a prescribing register. A random sample of 150 DNs from 32 primary care centers in Sweden was invited. DNs' ability to prescribe is used to a relatively small extent and access to "opportunities" and "informal power" seems to be the most important structural empowerment conditions for increased prescribing frequency and positive opinions about prescribing. The results support Kanter's theory of structural empowerment. This article regarding restricted prescribing shows how important structural conditions/empowerment is to DNs' prescribing and employers have to enhance nurses' access to especially the structures "opportunities" and "informal power" to increase nurse prescribing. More targeted support and training are needed in different prescribing areas to make use of DNs' prescription qualification to a greater extent. ©2015 American Association of Nurse Practitioners.

PHYSICIAN PRESCRIBING BEHAVIOR AND ITS IMPACT ON PATIENT-LEVEL OUTCOMES

Joyce, Geoffrey F.; Carrera, Mariana; Goldman, Dana P.; Sood, Neeraj

2013-01-01

OBJECTIVE Concerns over rising drug costs, pharmaceutical advertising and potential conflicts of interest have focused attention on physician prescribing behavior. We examine how broadly physicians prescribe within the ten most prevalent therapeutic classes, the factors affecting their choices, and its impact on patient-level outcomes. STUDY DESIGN Retrospective study from 2005 to 2007 examining prescribers with at least five initial prescriptions within a class from 2005–2007. Medical and pharmacy claims are linked to prescriber information from 146 different health plans, reflecting 1,975 to 8,923 unique providers per drug class. METHODS Primary outcomes are the number of distinct drugs in a class initially prescribed by a physician over 1- and 3-year periods, medication possession ratio, and out of pocket costs. RESULTS In 8 of 10 therapeutic classes, the median physician prescribes at least 3 different drugs and less than one in six physicians prescribes only brand drugs. Physicians prescribing only one or two drugs in a class are more likely to prescribe the most advertised drug. Physicians who prescribe fewer drugs are less likely to see patients with other comorbid conditions and varied formulary designs. Prescribing fewer drugs is associated with lower rates of medication adherence and higher out-of-pocket costs for drugs, but the effects are small and inconsistent across classes. CONCLUSIONS Physicians prescribe more broadly than commonly perceived. Though narrow prescribers are more likely to prescribe highly advertised drugs, few physicians prescribe these drugs exclusively. Narrow prescribing has modest effects on medication adherence and out of pocket costs in some classes. PMID:22216870

[TRIAP]-derived decoy peptides have anti-inflammatory properties. In this study, we synthesized a TRIAP-derived decoy peptide (TR6) containing, the N-terminal portion of the third helical region of the [TIRAP] TIR domain (sequence "N"-RQIKIWFQNRRMKWK and -KPGFLRDPWCKYQML-"C"). We evaluated the effects of TR6 on lipopolysaccharide-induced mastitis in mice. In vivo, the mastitis model was induced by LPS administration for 24h, and TR6 treatment was initiated 1h before or after induction of LPS. In vitro, primary mouse mammary epithelial cells and neutrophils were used to investigate the effects of TR6 on LPS-induced inflammatory responses. The results showed that TR6 significantly inhibited mammary gland hisopathologic changes, MPO activity, and LPS-induced production of TNF-α, IL-1β and IL-6. In vitro, TR6 significantly inhibited LPS-induced TNF-α and IL-6 production and phosphorylation of NF-κB and MAPKs. In conclusion, this study demonstrated that the anti-inflammatory effect of TR6 against LPS-induced mastitis may be due to its ability to inhibit TLR4-mediated NF-κB and MAPK signaling pathways. TR6 may be a promising therapeutic reagent for mastitis treatment. Copyright © 2015. Published by Elsevier B.V.

The Orphan Nuclear Receptor TR4 Is a Vitamin A-activated Nuclear Receptor

DOE Office of Scientific and Technical Information (OSTI.GOV)

Zhou, X. Edward; Suino-Powell, Kelly M.; Xu, Yong

2015-11-30

Testicular receptors 2 and 4 (TR2/4) constitute a subgroup of orphan nuclear receptors that play important roles in spermatogenesis, lipid and lipoprotein regulation, and the development of the central nervous system. Currently, little is known about the structural features and the ligand regulation of these receptors. Here we report the crystal structure of the ligand-free TR4 ligand binding domain, which reveals an autorepressed conformation. The ligand binding pocket of TR4 is filled by the C-terminal half of helix 10, and the cofactor binding site is occupied by the AF-2 helix, thus preventing ligand-independent activation of the receptor. However, TR4 exhibitsmore » constitutive transcriptional activity on multiple promoters, which can be further potentiated by nuclear receptor coactivators. Mutations designed to disrupt cofactor binding, dimerization, or ligand binding substantially reduce the transcriptional activity of this receptor. Importantly, both retinol and retinoic acid are able to promote TR4 to recruit coactivators and to activate a TR4-regulated reporter. These findings demonstrate that TR4 is a ligand-regulated nuclear receptor and suggest that retinoids might have a much wider regulatory role via activation of orphan receptors such as TR4.« less

TR32DB - Management of Research Data in a Collaborative, Interdisciplinary Research Project

NASA Astrophysics Data System (ADS)

Curdt, Constanze; Hoffmeister, Dirk; Waldhoff, Guido; Lang, Ulrich; Bareth, Georg

2015-04-01

The management of research data in a well-structured and documented manner is essential in the context of collaborative, interdisciplinary research environments (e.g. across various institutions). Consequently, set-up and use of a research data management (RDM) system like a data repository or project database is necessary. These systems should accompany and support scientists during the entire research life cycle (e.g. data collection, documentation, storage, archiving, sharing, publishing) and operate cross-disciplinary in interdisciplinary research projects. Challenges and problems of RDM are well-know. Consequently, the set-up of a user-friendly, well-documented, sustainable RDM system is essential, as well as user support and further assistance. In the framework of the Transregio Collaborative Research Centre 32 'Patterns in Soil-Vegetation-Atmosphere Systems: Monitoring, Modelling, and Data Assimilation' (CRC/TR32), funded by the German Research Foundation (DFG), a RDM system was self-designed and implemented. The CRC/TR32 project database (TR32DB, www.tr32db.de) is operating online since early 2008. The TR32DB handles all data, which are created by the involved project participants from several institutions (e.g. Universities of Cologne, Bonn, Aachen, and the Research Centre Jülich) and research fields (e.g. soil and plant sciences, hydrology, geography, geophysics, meteorology, remote sensing). Very heterogeneous research data are considered, which are resulting from field measurement campaigns, meteorological monitoring, remote sensing, laboratory studies and modelling approaches. Furthermore, outcomes like publications, conference contributions, PhD reports and corresponding images are regarded. The TR32DB project database is set-up in cooperation with the Regional Computing Centre of the University of Cologne (RRZK) and also located in this hardware environment. The TR32DB system architecture is composed of three main components: (i) a file-based data

IMPORTANCE “Nudges” that influence decision making through subtle cognitive mechanisms have been shown to be highly effective in a wide range of applications, but there have been few experiments to improve clinical practice. OBJECTIVE To investigate the use of a behavioral “nudge” based on the principle of public commitment in encouraging the judicious use of antibiotics for acute respiratory infections (ARIs). DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial in 5 outpatient primary care clinics. A total of 954 adults had ARI visits during the study timeframe: 449 patients were treated by clinicians randomized to the posted commitment letter (335 in the baseline period, 114 in the intervention period); 505 patients were treated by clinicians randomized to standard practice control (384 baseline, 121 intervention). INTERVENTIONS The intervention consisted of displaying poster-sized commitment letters in examination rooms for 12 weeks. These letters, featuring clinician photographs and signatures, stated their commitment to avoid inappropriate antibiotic prescribing for ARIs. MAIN OUTCOMES AND MEASURES Antibiotic prescribing rates for antibiotic-inappropriate ARI diagnoses in baseline and intervention periods, adjusted for patient age, sex, and insurance status. RESULTS Baseline rates were 43.5% and 42.8% for control and poster, respectively. During the intervention period, inappropriate prescribing rates increased to 52.7% for controls but decreased to 33.7% in the posted commitment letter condition. Controlling for baseline prescribing rates, we found that the posted commitment letter resulted in a 19.7 absolute percentage reduction in inappropriate antibiotic prescribing rate relative to control (P = .02). There was no evidence of diagnostic coding shift, and rates of appropriate antibiotic prescriptions did not diminish over time. CONCLUSIONS AND RELEVANCE Displaying poster-sized commitment letters in examination rooms decreased inappropriate

Objectives: Pharmacists in Canadian provinces are at different stages of applying prescribing legislation into practice. The purpose of this environmental scan was to examine differences in legislation, remuneration, professional uptake, continuing education requirements and continuing education resources relating to pharmacist prescribing for ambulatory ailments, with a focus on continuing education. Methods: Data were collected between May and December 2016 using websites and communication with provincial professional regulatory bodies, advocacy bodies, drug coverage programs and other organizations that offer continuing education for pharmacists. Results: Training requirements to prescribe for ambulatory ailments vary provincially, including no training requirements, online tutorials and a comprehensive application process. Government-funded remuneration for prescribing services is absent in most provinces. Pharmacist uptake of the training required to obtain prescribing authority ranges from 30% to 100% of pharmacists. Continuing education programs on the topic of prescribing across the country include online courses, in-person courses, webinars, panel discussions and preparation courses. Conclusion: Many aspects of pharmacist prescribing for ambulatory ailments, including the style and content of continuing education resources, vary from province to province. Further research on this topic would help to determine the effect of these differences on the success of incorporating pharmacist prescribing into practice. PMID:28894501

How is medication prescribing ceased? A systematic review.

Medication prescribing is a complex process where the focus tends to be on starting new medication, changing a drug regimen, and continuing a drug regimen. On occasion, a prudent approach to prescribing may necessitate ending an ongoing course of medication, either because it should not have been started in the first place; because its continued use would cause harm; or because the medication is no longer effective. To identify effective strategies for stopping pre-existing prescribing in situations where continued prescribing may no longer be clinically warranted. Systematic searches for English-language reports of experimental and quasi-experimental research were conducted in PubMed (1951-November 2009), EMBASE (1966-September 2008), and International Pharmaceutical Abstract b (1970-September 2008). A manual search for relevant review articles and a keyword search of a local database produced by a previous systematic search for prescribing influence and intervention research were also conducted. Following initial title screening for relevance 2 reviewers, using formal assessment and data extraction tools, independently assessed abstracts for relevance and full studies for quality before extracting data from studies selected for inclusion. Of 1306 articles reviewed, 12 were assessed to be of relevant, high-quality research. A variety of drugs were examined in the included studies with benzodiazepines the most common. Studies included in the review tested 9 different types of interventions. Effective interventions included patient-mediated interventions, manual reminders to prescribers, educational materials given to patients, a face-to-face intervention with prescribers, and a case of regulatory intervention. Partially effective interventions included audit and feedback, electronic reminders, educational materials alone sent to prescribers, and distance communication combined with educational materials sent to prescribers.

e-Learning initiatives to support prescribing

Preparing medical students to prescribe is a major challenge of undergraduate education. They must develop an understanding of clinical pharmacology and acquire knowledge about drugs and therapeutics, as well as the skills to prescribe for individual patients in the face of multiple variables. The task of delivering the learning required to achieve these attributes relies upon limited numbers of teachers, who have increasingly busy clinical commitments. There is evidence that training is currently insufficient to meet the demands of the workplace. e-Learning provides an opportunity to improve the learning experience. The advantages for teachers are improved distribution of learning content, ease of update, standardization and tracking of learner activities. The advantages for learners are ease of access, greater interactivity and individual choice concerning the pace and mix of learning. Important disadvantages are the considerable resource required to develop e-Learning projects and difficulties in simulating some aspects of the real world prescribing experience. Pre-requisites for developing an e-Learning programme to support prescribing include academic expertise, institutional support, learning technology services and an effective virtual learning environment. e-Learning content might range from complex interactive learning sessions through to static web pages with links. It is now possible to simulate and provide feedback on prescribing decisions and this will improve with advances in virtual reality. Other content might include a student formulary, self-assessment exercises (e.g. calculations), a glossary and an on-line library. There is some evidence for the effectiveness of e-Learning but better research is required into its potential impact on prescribing. PMID:22509885

Generic medicines: Greek physicians' perceptions and prescribing practices.

The penetration of generic drugs in the Greek pharmaceutical market is placed among the weakest in the EU. The Greek regulatory framework does not systematically support the development of this subsector and physicians are not provided with incentives for prescribing generics. The aim of this study was to investigate the prescribing profile of physicians in Greece with a focus on the factors that influence their decision on generics prescribing. A structured questionnaire was sent by mail to a random national sample of 1463 physicians, stratified by sex, specialty and geographical region. The response rate was 82.3%. Greek physicians have a positive view on generics but they prefer to prescribe the original products. According to our analysis, physician's age and their opinion on generics' efficacy and effectiveness are identified as important determinants of their prescribing decision. The primary reason that could make them change their prescribing habits is the appearance of side-effects. Patients' insurance coverage and income, as well as the drug cost are also referred as factors that influence their prescribing decision. Despite the fact that they do not usually prescribe generics in their clinical practice, they are willing to substitute an original drug by a generic product. Our findings suggest that Greek physicians could be persuaded to prescribe generic medicines, if a generic promotion policy was introduced in the country. To develop such a policy, a set of supply side and demand-side measures should be implemented along with provision of information on generics to physicians during their education and clinical practice.

Co-prescribing naloxone does not increase liability risk.

PubMed

Davis, Corey S; Burris, Scott; Beletsky, Leo; Binswanger, Ingrid

2016-01-01

The opioid overdose epidemic claims the lives of tens of thousands of Americans every year. Opioid overdose is reversible by the administration of naloxone, a pure antagonist now available in formulations specifically designed and labeled for layperson use. Despite broad support for layperson access to naloxone from professional organizations, health officials, and clinical experts, qualitative studies suggest that some providers have concerns about legal risks associated with naloxone prescribing, particularly co-prescribing naloxone to pain patients. Such concerns are unfounded. The legal risk associated with prescribing naloxone is no higher than that associated with any other medication and is lower than many. Additionally, laws in a majority of states provide explicit legal protections for providers who prescribe or dispense naloxone, in many cases extending this protection to prescriptions issued to friends, family members, and others. In this large and increasing number of states, the liability risk of prescribing or dispensing naloxone in good faith to a patient at risk of overdose (or, in states where such prescribing is permitted, to an associate of such a patient) is either extremely low or absent entirely. Where a prescriber determines, in his or her clinical judgment, that a patient is at risk of overdose, co-prescribing naloxone is a reasonable and prudent clinical and legal decision. No clinician should fail or refuse to issue such a prescription based on liability concerns.

Why are patients prescribed proton pump inhibitors? Retrospective analysis of link between morbidity and prescribing in the General Practice Research Database

Bashford, James N R; Norwood, Jeff; Chapman, Stephen R

1998-01-01

Objectives: To establish the relation between new prescriptions for proton pump inhibitors and recorded upper gastrointestinal morbidity within a large computerised general practitioner database. Design: Retrospective survey of morbidity and prescribing data linked to new prescriptions for proton pump inhibitors and comparison with licensed indications between 1991 and 1995. Setting: General Practice Research Database and prescribing analysis and cost (PACT) data for the former West Midlands region. Subjects: Information for 612 700 patients in the General Practice Research Database. Anonymous PACT data for all general practitioners in West Midlands region. Main outcome measures: Diagnostic codes linked to the first prescriptions issued for proton pump inhibitors; relation between new prescriptions and licensed indications; yearly change in ratio of new to repeat prescriptions and prescribing volumes measured as defined daily doses. Results: Oesophagitis was the commonest recorded indication in 1991, accounting for 31% of new prescriptions, but was third in 1995 (14%). During the study new prescriptions increased substantially, especially for duodenal disease (780%) and non-ulcer dyspepsia (690%). In 1995 non-specific morbidity accounted for 46% of new prescriptions. The total volume of prescribing rose 10-fold between 1991 and 1995, when repeat prescribing accounted for 77% of the total. Conclusions: Changes in recorded morbidity associated with new prescriptions of proton pump inhibitors did not necessarily reflect changes in licensed indications. Although general practitioners seemed to respond to changes in licensing, particularly for duodenal and gastric disease, prescribing for unlicensed indications non-ulcer dyspepsia and non-specific abdominal pain increased. Key messages There has been much speculation about the reasons behind the substantial rise in prescribing of proton pump inhibitors, especially their use for minor symptoms. We used the General

To estimate the impact of the first year of new Pharmaceutical Benefits Scheme (PBS) prescribing criteria that dictate eligibility for national health scheme subsidy of testosterone prescribing. Analysis of cumulative PBS data. Retrospective analysis of testosterone prescribing from PBS data. Nil MAIN OUTCOME MEASURES: PBS expenditure analysed by total expenditure, by state, and by product type as well as the age, indication, and prescriber type for new testosterone treatment. Total PBS expenditure continued to exceed $20 million in 2014 before declining from 2015 with changes that were uniform by state and product type. Prior to 2015, over 80% were for men aged over 40 years of age for low circulating testosterone in the absence of reproductive system disorders ("Low T") initiated by GPs. From 2015, these features were markedly reduced without changing the numbers of new prescriptions for pathological reproductive disorders or specialist initiations. The short-term impact of 2015 PBS criteria showed highly effective and well-targeted curbing of off-label testosterone prescribing. The findings indicate that the main driver for the recent upsurge in testosterone prescribing was treatment of middle-aged men for "Low T" initiated by GPs. © 2017 Government of New South Wales.

The social act of electronic medication prescribing.

PubMed

Aarts, Jos

2013-01-01

Prescribing medication is embedded in social norms and cultures. In modern Western health care professionals and policy makers have attempted to rationalize medicine by addressing cost-effectiveness of diagnostic and therapeutic treatments and the development of guidelines and protocols based on the outcomes of clinical studies. These notions of cost-effectiveness and evidence-based medicine have also been embedded in technology such as electronic prescribing systems. Such constraining systems may clash with the reality of clinical practice, where formal boundaries of responsibility and authorization are often blurred. Such systems may therefore even impede patient care. Medication is seen as the essence of medical practice. Prescribing is a social act. In a hospital medications may be aimed at treating a patient for a specific condition, in primary care the professional often meets the patient with her or his social and cultural notions of a health problem. The author argues that the design and implementation of electronic prescribing systems should address the social and cultural context of prescribing. Especially in primary care, where health problems are often ill defined and evidence-based medicine guidelines do not always work as intended, studies need to take into account the sociotechnical character of electronic prescribing systems.

Customization in Prescribing for Bipolar Disorder

2011-01-01

For many disorders, patient heterogeneity requires physicians to customize their treatment to each patient’s needs. We test for the existence of customization in physicians’ prescribing for bipolar disorder, using data from a naturalistic clinical effectiveness trial of bipolar disorder treatment (STEP-BD), which did not constrain physician prescribing. Multinomial logit is used to model the physician’s choice among five combinations of drug classes. We find that our observed measure of the patient’s clinical status played only a limited role in the choice among drug class combinations, even for conditions such as mania that are expected to affect class choice. However, treatment of a patient with given characteristics differed widely depending on which physician was seen. The explanatory power of the model was low. There was variation within each physician’s prescribing, but the results do not suggest a high degree of customization in physicians’ prescribing, based on our measure of clinical status.

Opioid analgesic use and disorders have dramatically increased among the general American population and those receiving methadone maintenance treatment (MMT). Most research among MMT patients focuses on opioid analgesics misuse or disorders; few studies focus on MMT patients prescribed opioid analgesics. We describe demographic, clinical, and substance use characteristics of MMT patients prescribed opioid analgesics and compare them with MMT patients not prescribed opioid analgesics. We conducted a cross-sectional secondary data analysis using screening interviews from a parent study. From 2012 to 2015, we recruited adults from 3 MMT Bronx clinics. Questionnaire data included patterns of opioid analgesic use, substance use, comorbid illnesses, and demographic characteristics. Our main dependent variable was patients' report of currently taking prescribed opioid analgesics. To compare characteristics between MMT patients prescribed and not prescribed opioid analgesics, we conducted chi-square tests, t tests, and Mann-Whitney U tests. Of 611 MMT patients, most reported chronic pain (62.0%), hepatitis C virus (HCV) infection (52.1%), and current use of illicit substances (64.2%). Of the 29.8% who reported currently taking prescribed opioid analgesics, most misused their opioid analgesics (57.5%). Patients prescribed (versus not prescribed) opioid analgesics were more likely to report human immunodeficiency virus (HIV) infection (adjusted odds ratio [aOR] = 1.6, 95% confidence interval [CI]: 1.1-2.3) and chronic pain (aOR = 7.6, 95% CI: 4.6-12.6). Among MMT patients primarily in 3 Bronx clinics, nearly one third reported taking prescribed opioid analgesics. Compared with patients not prescribed opioid analgesics, those prescribed opioid analgesics were more likely to report chronic pain and HIV infection. However, between these patients, there was no difference in illicit substance use. These findings highlight the complexity of addressing chronic pain in MMT patients.

Our main dependent variable was patients’ report of currently taking prescribed opioid analgesics. To compare characteristics between MMT patients prescribed and not prescribed opioid analgesics, we conducted chi-squared tests, t-tests, and Mann-Whitney U tests. Results Of 611 MMT patients, most reported chronic pain (62.0%), HCV infection (52.1%), and currently using illicit substances (64.2%). Of the 29.8% who reported currently taking prescribed opioid analgesics, most misused their opioid analgesics (57.5%). Patients prescribed (versus not prescribed) opioid analgesics were more likely to report HIV infection (aOR=1.6, 95% CI: 1.1–2.3) and chronic pain (aOR=7.6, 95% CI: 4.6–12.6). Conclusion Among MMT patients primarily in three Bronx clinics, nearly one-third reported taking prescribed opioid analgesics. Compared to patients not prescribed opioid analgesics, those prescribed opioid analgesics were more likely to report chronic pain and HIV infection. However, between these patients, there was no difference in illicit substance use. These findings highlight the complexity of addressing chronic pain in MMT patients. PMID:26731299

Superconductivity in Cage Compounds LaTr2Al20 with Tr = Ti, V, Nb, and Ta

Electrical resistivity, magnetic susceptibility, and specific heat measurements on single crystals of LaTr2Al20 (Tr = Ti, V, Nb, and Ta) revealed that these four compounds exhibit weak-coupling superconductivity with transition temperatures Tc = 0.46, 0.15, 1.05, and 1.03 K, respectively. LaTi2Al20 is most probably a type-I superconductor, which is quite rare among intermetallic compounds. Single-crystal X-ray diffraction suggests "rattling" anharmonic large-amplitude oscillations of Al ions (16c site) on the Al16 cage, while no such feature is suggested for the cage-center La ion. Using a parameter dGFS quantifying the "guest free space" of the cage-center ion, we demonstrate that nonmagnetic RTr2Al20 superconductors are classified into two groups, i.e., (A) dGFS ≠ 0 and Tc correlates with dGFS, and (B) dGFS ≃ 0 and Tc seems to be governed by other factors.

e-Learning initiatives to support prescribing.

PubMed

Maxwell, Simon; Mucklow, John

2012-10-01

Preparing medical students to prescribe is a major challenge of undergraduate education. They must develop an understanding of clinical pharmacology and acquire knowledge about drugs and therapeutics, as well as the skills to prescribe for individual patients in the face of multiple variables. The task of delivering the learning required to achieve these attributes relies upon limited numbers of teachers, who have increasingly busy clinical commitments. There is evidence that training is currently insufficient to meet the demands of the workplace. e-Learning provides an opportunity to improve the learning experience. The advantages for teachers are improved distribution of learning content, ease of update, standardization and tracking of learner activities. The advantages for learners are ease of access, greater interactivity and individual choice concerning the pace and mix of learning. Important disadvantages are the considerable resource required to develop e-Learning projects and difficulties in simulating some aspects of the real world prescribing experience. Pre-requisites for developing an e-Learning programme to support prescribing include academic expertise, institutional support, learning technology services and an effective virtual learning environment. e-Learning content might range from complex interactive learning sessions through to static web pages with links. It is now possible to simulate and provide feedback on prescribing decisions and this will improve with advances in virtual reality. Other content might include a student formulary, self-assessment exercises (e.g. calculations), a glossary and an on-line library. There is some evidence for the effectiveness of e-Learning but better research is required into its potential impact on prescribing. © 2012 The Authors.

New ternary arsenides AE 3TrAs 3 (AE = Sr, Ba; Tr = Al, Ga) and their phosphide analogs Sr 3GaP 3 and Ba 3AlP 3 have been prepared by reactions of the respective elements at high temperatures. Single-crystal X-ray diffraction studies reveal that Sr 3AlAs 3 and Ba 3AlAs 3 adopt the Ba 3AlSb 3-type structure (Pearson symbol oC56, space group Cmce, Z = 8). This structure is also realized for Sr 3GaP 3 and Ba 3AlP 3. Likewise, the compounds Sr 3GaAs 3 and Ba 3GaAs 3 crystallize with the Ba 3GaSb 3-type structure (Pearson symbol oP56, space groupmore » Pnma, Z = 8). Both structures are made up of isolated pairs of edge-shared AlPn 4 and GaPn 4 tetrahedra (Pn = pnictogen, i.e., P or As), separated by the alkaline-earth Sr 2+ and Ba 2+ cations. In both cases, there are no homoatomic bonds, hence, regardless of the slightly different atomic arrangements, both structures can be rationalized as valence-precise [AE 2+] 3[Tr 3+][Pn 3-] 3, or rather [AE 2+] 6[Tr 2Pn 6] 12-, i.e., as Zintl phases.« less

Type-1 regulatory T (TR1) cells are Foxp3-negative IL-10-producing CD4+ T cells with potent immune suppressive properties but their requirements for lineage development have remained elusive. Here we show that TR1 cells constitute the most abundant regulatory population after allogeneic bone marrow transplantation (BMT), express the transcription factor Eomesodermin (Eomes) and are critical for the prevention of graft-versus-host disease (GVHD). We demonstrate that Eomes is required for TR1 cell differentiation during which it acts in concert with the transcription factor B-lymphocyte-induced maturation protein-1 (Blimp-1) by transcriptionally activating IL-10 expression and repressing differentiation into other Th lineages. We further show that Eomes induction in TR1 cells requires T-bet and donor macrophage-derived IL-27. We thus define the cellular and transcriptional control of TR1 cell differentiation during bone marrow transplantation, opening new avenues to therapeutic manipulation. PMID:28738016

Purpose To describe the practice settings and prescribing practices of oncology pharmacists with additional prescribing authorization. Methods A descriptive, cross-sectional survey of all oncology pharmacists in Alberta was conducted using a web-based questionnaire over four weeks between March and April 2016. Pharmacists were identified from the Cancer Services Pharmacy Directory and leadership staff in Alberta Health Services. Descriptive statistics were used to describe the practice setting, prescribing practices, motivators to apply for additional prescribing authorization, and the facilitators and barriers of prescribing. Logistic regression was used to explore factors associated with having additional prescribing authorization. Results The overall response rate was 41% (71 of 175 pharmacists). Oncology pharmacists with additional prescribing authorization made up 38% of respondents. They primarily worked in urban, tertiary cancer centers, and practiced in ambulatory care. The top 3 clinical activities they participated in were medication reconciliation, medication counseling/education, and ambulatory patient assessment. Respondents thought additional prescribing authorization was most useful for ambulatory patient assessment and follow-up. Antiemetics were prescribed the most often. The median number of prescriptions written in an average week of clinical work was 5. Competence, self-confidence, and the potential impact on patient care/perceived impact on work environment were the strongest facilitators of prescribing. The strongest motivators to apply for additional prescribing authorization were relevancy to practice, the potential for increased efficiency, and advancing the profession. Conclusion The current majority of oncology pharmacist prescribing in Alberta occurs in ambulatory care with a large focus on antiemetic prescribing. Pharmacists found additional prescribing authorization most useful for ambulatory patient assessment and follow-up.

Control of invasive weeds with prescribed burning

2006-01-01

Prescribed burning has primarily been used as a tool for the control of invasive late-season annual broadleaf and grass species, particularly yellow starthistle, medusahead, barb goatgrass, and several bromes. However, timely burning of a few invasive biennial broadleaves (e.g., sweetclover and garlic mustard), perennial grasses (e.g., bluegrasses and smooth brome), and woody species (e.g., brooms and Chinese tallow tree) also has been successful. In many cases, the effectiveness of prescribed burning can be enhanced when incorporated into an integrated vegetation management program. Although there are some excellent examples of successful use of prescribed burning for the control of invasive species, a limited number of species have been evaluated. In addition, few studies have measured the impact of prescribed burning on the long-term changes in plant communities, impacts to endangered plant species, effects on wildlife and insect populations, and alterations in soil biology, including nutrition, mycorrhizae, and hydrology. In this review, we evaluate the current state of knowledge on prescribed burning as a tool for invasive weed management.

Aims To demonstrate an epidemiological method to assess predictors of prescribing errors. Methods A retrospective case-control study, comparing prescriptions with and without errors. Results Only prescriber and drug characteristics were associated with errors. Prescriber characteristics were medical specialty (e.g. orthopaedics: OR: 3.4, 95% CI 2.1, 5.4) and prescriber status (e.g. verbal orders transcribed by nursing staff: OR: 2.5, 95% CI 1.8, 3.6). Drug characteristics were dosage form (e.g. inhalation devices: OR: 4.1, 95% CI 2.6, 6.6), therapeutic area (e.g. gastrointestinal tract: OR: 1.7, 95% CI 1.2, 2.4) and continuation of preadmission treatment (Yes: OR: 1.7, 95% CI 1.3, 2.3). Conclusions Other hospitals could use our epidemiological framework to identify their own error predictors. Our findings suggest a focus on specific prescribers, dosage forms and therapeutic areas. We also found that prescriptions originating from general practitioners involved errors and therefore, these should be checked when patients are hospitalized. PMID:11874397

Thus far, research on plant hemoglobins (Hbs) has mainly concentrated on symbiotic and non-symbiotic Hbs, and information on truncated Hbs (TrHbs) is scarce. The aim of this study was to examine the origin, structure and localization of the truncated Hb (PttTrHb) of hybrid aspen (Populus tremula L. × tremuloides Michx.), the model system of tree biology. Additionally, we studied the PttTrHb expression in relation to non-symbiotic class1 Hb gene (PttHb1) using RNAi-silenced hybrid aspen lines. Both the phylogenetic analysis and the three-dimensional (3D) model of PttTrHb supported the view that plant TrHbs evolved vertically from a bacterial TrHb. The 3D model suggested that PttTrHb adopts a 2-on-2 sandwich of α-helices and has a Bacillus subtilis -like ligand-binding pocket in which E11Gln and B10Tyr form hydrogen bonds to a ligand. However, due to differences in tunnel cavity and gate residue (E7Ala), it might not show similar ligand-binding kinetics as in Bs-HbO (E7Thr). The immunolocalization showed that PttTrHb protein was present in roots, stems as well as leaves of in vitro -grown hybrid aspens. In mature organs, PttTrHb was predominantly found in the vascular bundles and specifically at the site of lateral root formation, overlapping consistently with areas of nitric oxide (NO) production in plants. Furthermore, the NO donor sodium nitroprusside treatment increased the amount of PttTrHb in stems. The observed PttTrHb localization suggests that PttTrHb plays a role in the NO metabolism.

To describe facilitators and barriers in relation to the growth of nurse prescribing competence from the perspective of the nurses studying in a prescribing programme. The number of nurses enrolled in a nurse prescribing programme is rapidly increasing in Finland. However, few studies on nurse prescribing education are available and therefore research is needed, particularly from the point of view of nurses studying in the programme. The descriptive, qualitative study used the text of student online learning diaries as data during a 14-month prescribing programme. The sample consisted of 31 nurses, public health nurses or midwives enrolled in a prescribing programme at a university of applied sciences. The data were analysed using the inductive analysis method. The growth of nurses' prescribing competence was facilitated by learning clinical examination of the patient, networking with peers, receiving support from the workplace and supervisors, doctors' positive attitude towards nurse prescribing and being able to apply competencies directly to nursing practice. The barriers to the growth of nurses' prescribing competence were unclear job description, incomplete care plans and concerns about how consultation with doctors will be organised and realised. The results show that, for the purpose of developing the new role and position of nurse prescribers, educators and nursing managers must invest more in staff awareness of nurse prescribing education and also offer more support to nurse prescribers in their workplaces. The results of this study can be used especially in countries where nurse prescribing education is only in the process of being planned or has just been started. Heads of nursing and educators in prescribing education will benefit from the results when creating expanded job descriptions for nurses and supporting networking between students during the period of training. © 2016 John Wiley & Sons Ltd.

Characteristics of high and low prescribers of antibiotics in German primary care were analysed using population data. We aimed to evaluate differences in prescribing rates and factors being associated with high prescribing, and whether high prescribers made the diagnosis of perceived bacterial infections more often. Routine data were provided by the Bavarian Association of Statutory Health Insurance Physicians. Routine data are delivered by primary care practices on a quarterly basis. We analysed data from 2011 and 2012. Patients older than 15 years with respiratory tract infections consulting a primary care physician were selected (6.647 primary care practices). Patient and physician characteristics associated with high prescribing were identified using stepwise logistic regression. Mean prescribing rate of antibiotics was 24.9%. Prescribing rate for high prescribers was 43.5% compared to 8.5% for low prescribers. High prescribers made the diagnosis of perceived bacterial infections more often (Mhigh = 64.5%, Mlow = 45.2%). In the adjusted regression model, perceived bacterial infections were strongly associated with high prescribing (OR = 13.9, 95% CI [10.2, 18.8]). Treating patients with comorbidities was associated with lower prescribing of antibiotics (OR = 0.6, 95% CI [0.4, 0.8]). High prescribers had a higher practice volume, a higher degree of prescribing dominance, and were situated more often in deprived areas and in rural settings. Compared to findings of studies in other European countries, prescribing rates were low. There was a considerable difference between prescribing rates of high and low prescribers. Diagnostic labelling was the best predictor for high prescribing. Current guidelines recommend considering antibiotic treatment for patients with co-morbidities. In our study, treating a large number of high-risk patients was not associated with high prescribing.

Ross, Sarah; Maxwell, Simon

2012-01-01

Prescribing is one of the commonest tasks expected of new doctors and is a complex process involving a mixture of knowledge, judgement and skills. Preparing graduates to be prescribers is one of the greatest challenges of modern undergraduate medical education and there is some evidence to suggest that training could be improved. The aims of this article are (i) to review some of the challenges of delivering effective prescribing education, (ii) to provide a clear statement of the learning outcomes in clinical pharmacology and prescribing that should be expected of all medical graduates and (iii) to describe a curriculum that might enable students to achieve these outcomes. We build on the previous curriculum recommendations of the British Pharmacological Society and take into account those of other key bodies, notably the General Medical Council. We have also reviewed relevant evidence from the literature and set our work in the context of recent trends in medical education. We divide our recommended learning objectives into four sections: principles of clinical pharmacology, essential drugs, essential therapeutic problems and prescribing skills. Although these will not necessarily be accepted universally we believe that they will help those who design and map undergraduate curricula to explore potential gaps and identify improvements.

2016-12-01

Antipsychotic use among young children has grown rapidly despite a lack of approval by the U.S. Food and Drug Administration (FDA) for broad use in this age group. Characteristics of physicians who prescribed antipsychotics to young children were identified, and prescribing patterns involving young children and adults were compared. Physician-level prescribing data from IMS Health's Xponent database were linked with American Medical Association Masterfile data and analyzed. The sample included all U.S. psychiatrists and a random sample of 5% of family medicine physicians who wrote at least ten antipsychotic prescriptions per year from 2008 to 2011 (N=31,713). Logistic and hierarchical binomial regression models were estimated to examine physician prescribing for children ages zero to nine, and the types and numbers of ingredients used for children versus adults ages 20 to 64 were compared. Among antipsychotic prescribers, 42.2% had written at least one antipsychotic prescription for young children. Such prescribing was more likely among physicians age ≤39 versus ≥60 (odds ratio [OR]=1.70) and physicians in rural versus nonrural areas (OR=1.11) and was less likely among males (OR=.93) and graduates of a top-25 versus a lower-ranked U.S. medical school (OR=.87). Among physicians who prescribed antipsychotics to young children and adults, 75.0% of prescriptions for children and 35.7% of those for adults were for drugs with an FDA-approved indication for that age. Fewer antipsychotic agents were prescribed for young children (median=2) versus adults (median=7). Prescribing antipsychotics for young children was relatively common, but prescribing patterns differed between young children and adults.

Few studies describe drug utilization in pregnancy focusing on prescribing practices. This study is part of a larger survey on perinatal care in the City of Rio de Janeiro, Brazil. The type of hospital (public, contracted out by the Unified National Health System, or private) determined the stratification of 10,072 hospitalized post-partum women, who were asked about medication used during pregnancy. Hospital records supplied information on drugs prescribed during labor. Drugs were classified according to the Anatomical Therapeutic Chemical (ATC) system. Another system was used for specific cases of referred use. A mean of 2.08 drugs was prescribed during labor, and a mean of 2.3 was reported during pregnancy. Anesthetics, antibiotics, oxytocin, and analgesics were the most frequently prescribed during labor, with significant differences between strata. Ferrous sulfate, vitamins, scopolamine, and acetaminophen were the main drugs reported during pregnancy. Women who had attempted abortion referred use of various kinds of tea (49.7%) and misoprostol (9.2%). The drug utilization pattern was consistent with the literature. This study offers knowledge on prescribing patterns during labor and self-reported use during pregnancy in both the public and private sectors.

Distance Mapping in Proteins Using Fluorescence Spectroscopy: The Tryptophan-Induced Quenching (TrIQ) Method

PubMed Central

Mansoor, Steven E.; DeWitt, Mark A.; Farrens, David L.

2014-01-01

Studying the interplay between protein structure and function remains a daunting task. Especially lacking are methods for measuring structural changes in real time. Here we report our most recent improvements to a method that can be used to address such questions. This method, which we now call Tryptophan induced quenching (TrIQ), provides a straightforward, sensitive and inexpensive way to address questions of conformational dynamics and short-range protein interactions. Importantly, TrIQ only occurs over relatively short distances (~5 to 15 Å), making it complementary to traditional fluorescence resonance energy transfer (FRET) methods that occur over distances too large for precise studies of protein structure. As implied in the name, TrIQ measures the efficient quenching induced in some fluorophores by tryptophan (Trp). We present here our analysis of the TrIQ effect for five different fluorophores that span a range of sizes and spectral properties. Each probe was attached to four different cysteine residues on T4 lysozyme and the extent of TrIQ caused by a nearby Trp was measured. Our results show that for smaller probes, TrIQ is distance dependent. Moreover, we also demonstrate how TrIQ data can be analyzed to determine the fraction of fluorophores involved in a static, non-fluorescent complex with Trp. Based on this analysis, our study shows that each fluorophore has a different TrIQ profile, or "sphere of quenching", which correlates with its size, rotational flexibility, and the length of attachment linker. This TrIQ-based "sphere of quenching" is unique to every Trp-probe pair and reflects the distance within which one can expect to see the TrIQ effect. It provides a straightforward, readily accessible approach for mapping distances within proteins and monitoring conformational changes using fluorescence spectroscopy. PMID:20886836

Prescribed fires have many benefits, but existing ignition methods are dangerous, costly, or inefficient. This paper presents the design and evaluation of a micro-UAS that can start a prescribed fire from the air, while being operated from a safe distance and without the costs associated with aerial ignition from a manned aircraft. We evaluate the performance of the system in extensive controlled tests indoors. We verify the capabilities of the system to perform interior ignitions, a normally dangerous task, through the ignition of two prescribed fires alongside wildland firefighters.

Family medicine providers at a large family medicine clinic were surveyed regarding their impression of the impact, utility and safety of the Primary Care Prescribing Psychologist (PCPP) model in which a prescribing psychologist is embedded in a primary care clinic. This article describes the model and provides indications of its strengths and weaknesses as reported by medical providers who have utilized the model for the past 2 years. A brief history of prescribing psychology and the challenges surrounding granting psychologists the authority to prescribe psychotropic medication is summarized. Results indicate family medicine providers agree that having a prescribing psychologist embedded in the family medicine clinic is helpful to their practice, safe for patients, convenient for providers and for patients, and improves patient care. Potential benefits of integrating prescribing psychology into primary care are considered and directions for future research are discussed.

How Physician Perspectives on E-Prescribing Evolve over Time

Patel, Vaishali; Pfoh, Elizabeth R.; Kaushal, Rainu

2016-01-01

Summary Background Physicians are expending tremendous resources transitioning to new electronic health records (EHRs), with electronic prescribing as a key functionality of most systems. Physician dissatisfaction post-transition can be quite marked, especially initially. However, little is known about how physicians’ experiences using new EHRs for e-prescribing evolve over time. We previously published a qualitative case study about the early physician experience transitioning from an older to a newer, more robust EHR, in the outpatient setting, focusing on their perceptions of the electronic prescribing functionality. Objective Our current objective was to examine how perceptions about using the new HER evolved over time, again with a focus on electronic prescribing. Methods We interviewed thirteen internists at an academic medical center-affiliated ambulatory care clinic who transitioned to the new EHR two years prior. We used a grounded theory approach to analyze semi-structured interviews and generate key themes. Results We identified five themes: efficiency and usability, effects on safety, ongoing training requirements, customization, and competing priorities for the EHR. We found that for even experienced e-prescribers, achieving prior levels of perceived prescribing efficiency took nearly two years. Despite the fact that speed in performing prescribing-related tasks was highly important, most were still not utilizing system short cuts or customization features designed to maximize efficiency. Alert fatigue remained common. However, direct transmission of prescriptions to pharmacies was highly valued and its benefits generally outweighed the other features considered poorly designed for physician workflow. Conclusions Ensuring that physicians are able to do key prescribing tasks efficiently is critical to the perceived value of e-prescribing applications. However, successful transitions may take longer than expected and e-prescribing system features that

The perceived demand for and barriers to pharmacist prescribing in the community pharmacy setting were studied. Qualitative interviews were conducted with 19 consumers, 20 community pharmacists, and 8 reimbursement decision-makers from payer organizations between April and June 2015. Respondents were invited to participate in a daylong interview process online. Interviews with consumers and pharmacists were conducted using online bulletin board technology. Telephone interviews were conducted with reimbursement decision-makers. As with all qualitative research, the sample sizes used were restrictive and sufficient to gauge the perceptions of those respondents only. Interview responses were not intended to be generalizable to the groups or populations from which the respondents came. There was a continuum of interest in pharmacist prescribing across the three constituencies. Consumers were predominantly resistant to the notion; however, one third were more positive about the idea. Community pharmacists were more open, particularly when prescribing was restricted to a limited set of conditions or medications. Reimbursement decision-makers were most receptive to the notion. Key barriers to pharmacist prescribing included low awareness of current pharmacist prescribing authority among consumers, concerns about the adequacy of pharmacist training, potential conflicts of interest when the prescriber was also a dispenser, and potential liability issues. Consumer respondents were generally resistant to the notion of pharmacist prescribing, with most viewing pharmacists as dispensers and not prescribers. Community pharmacists were more open to the idea, while reimbursement decision-makers were the most receptive to the notion of pharmacist prescribing.

Nurse prescribing: radicalism or tokenism?

PubMed

McCartney, W; Tyrer, S; Brazier, M; Prayle, D

The creation of The Medical Products (Prescription by Nurses, etc.) Act 1992 has been generally welcomed by the nursing profession. This article seeks to introduce a note of scepticism about the assumed motivations for its introduction through an analysis of various legal, ethical, economic and political dimensions. In reviewing the position of nursing vis-à-vis medicine it is argued that one of the ways that nursing has sought to improve its professional position is to take on work previously done by doctors, and nurse prescribing can be seen in the context of the concurrent de-regulation of medicines, allowing greater access to medicines and therefore greater consumer choice. This de-regulation stems from the liberation ideology of the previous Conservative government. Viewed in this way nurse prescribing, particularly with reference to the limited nature of the nursing formulary, can be seen to be anomalous. In the light of this analysis, the reasons generally put forward (notably in the Crown Report 1989) for the introduction of nurse prescribing could be seen to be peripheral to its real purpose. It is argued that the most convincing reasons for its introduction relate to the medical profession as a social institution. It is proposed that the three primary aims behind the introduction of nurse prescribing are: the saving of money; the transfer of routine medical work to nursing; and a challenge to the professional monolith of medicine.

Prostaglandin E2 inhibits Tr1 cell differentiation through suppression of c-Maf

PubMed Central

Hooper, Kirsten Mary; Kong, Weimin

Prostaglandin E2 (PGE2), a major lipid mediator abundant at inflammatory sites, acts as a proinflammatory agent in models of inflammatory/autoimmune diseases by promoting CD4 Th1/Th17 differentiation. Regulatory T cells, including the IL-10 producing Tr1 cells counterbalance the proinflammatory activity of effector Th1/Th17 cells. Tr1 cell differentiation and function are induced by IL-27, and depend primarily on sustained expression of c-Maf in addition to AhR and Blimp-1. In agreement with the in vivo proinflammatory role of PGE2, here we report for the first time that PGE2 inhibits IL-27-induced differentiation and IL-10 production of murine CD4+CD49b+LAG-3+Foxp3- Tr1 cells. The inhibitory effect of PGE2 was mediated through EP4 receptors and induction of cAMP, leading to a significant reduction in c-Maf expression. Although PGE2 reduced IL-21 production in differentiating Tr1 cells, its inhibitory effect on Tr1 differentiation and c-Maf expression also occurred independent of IL-21 signaling. PGE2 did not affect STAT1/3 activation, AhR expression and only marginally reduced Egr-2/Blimp-1 expression. The effect of PGE2 on CD4+CD49b+LAG-3+ Tr1 differentiation was not associated with either induction of Foxp3 or IL-17 production, suggesting a lack of transdifferentiation into Foxp3+ Treg or effector Th17 cells. We recently reported that PGE2 inhibits the expression and production of IL-27 from activated conventional dendritic cells (cDC) in vivo and in vitro. The present study indicates that PGE2 also reduces murine Tr1 differentiation and function directly by acting on IL-27-differentiating Tr1 cells. Together, the ability of PGE2 to inhibit IL-27 production by cDC, and the direct inhibitory effect on Tr1 differentiation mediated through reduction in c-Maf expression, represent a new mechanistic perspective for the proinflammatory activity of PGE2.

Acutely transforming retrovirus AKT8 in rodent T cell lymphoma (Akt) phosphorylates and regulates the function of many cellular proteins involved in processes such as metabolism, apoptosis and proliferation. However, the precise mechanisms by which Akt promotes cell survival and inhibits apoptosis have been characterized in part only. TR3, an orphan receptor, functions as a transcription factor that can both positively or negatively regulate gene expression. We have reported previously that the translocation of TR3 from the nucleus to the mitochondria can elicit a proapoptotic effect in gastric cancer cells. In our present study, we demonstrate that Akt phosphorylates cytoplasmic TR3 through its physical interaction with the N-terminus of TR3. When coexpressed with Akt, TR3 mitochondrial targeting was blocked and this protein adopted a diffuse expression pattern in the cytoplasm. Moreover, Akt displayed an ability to disrupt the interaction of TR3 with Bcl-2, which is thought to be a critical requirement for mitochondrial TR3 to elicit apoptosis. Consistently, insulin was also found to induce the phosphorylation of TR3 and abolish 12-O-tetradecanoylphorbol-13-acetate-induced mitochondrial localization, which was dependent upon the activation of the phophatidylinositol-3-OH-kinase-Akt signaling pathway. Taken together, our current data demonstrate a unique role for Akt in inhibiting TR3 functions that are not related to transcriptional activity but that correlate with the regulation of its mitochondrial association. This may represent a novel signal pathway by which Akt exerts its antiapoptotic effects in gastric cancer cells, i.e. by regulating the phosphorylation and redistribution of orphan receptors.

Dental prescribing in Wales and associated public health issues.

PubMed

Karki, A J; Holyfield, G; Thomas, D

2011-01-08

Dental prescribing data in Wales have not been studied in detail previously. The analysis of national data available from Health Solutions Wales showed that dental prescribing in Wales accounted for 9% of total antibacterial prescribing in primary care in 2008. Penicillin and metronidazole constituted the bulk of antibiotics prescribed by dentists. Since the publication of National Institute for Health and Clinical Excellence (NICE) guidance (March 2008) on prophylaxis against infective endocarditis, dental prescriptions for amoxicillin 3g sachets and clindamycin capsules have decreased. Dental prescriptions for fluoride preparations increased in number from 2007 to 2008. Dental prescribing of controlled drugs raises no concern. The figure for antibiotic prescribing in Wales is similar to that of England. Nevertheless, the figure seems a little high, indicating potential inappropriate prescribing behaviour among dentists. Antibiotic resistance is a major public health issue and many patients each year die from infections from bacterial strains that are resistant to one or more antibiotics. Inappropriate use of antibiotics is a major cause of antibiotic resistance and every effort should be made to reduce the number of inappropriate antibiotic prescriptions in dental practice.

Air Pollution Episodes Associated with Prescribed Burns

Air pollution events associated with wildfires have been associated with extreme health impacts. Prescribed burns are an important tool to reduce the severity of wildfires. However, if undertaken during unfavourable meteorological conditions, they too have the capacity to trigger extreme air pollution events. The Australian state of New South Wales has increased the annual average area treated by prescribed burn activities by 45%, in order to limit wildfire activity. Prescribed burns need to be undertaken during meteorological conditions that allow the fuel load to burn, while still allowing the burn to remain under control. These conditions are similar to those that inhibit atmospheric dispersion, resulting in a fine balance between managing fire risk and managing ambient air pollution. During prescribed burns, the Sydney air shed can experience elevated particulate matter concentrations, especially fine particulates (PM2.5) that occasionally exceed national air quality standards. Using pollutant and meteorological data from sixteen monitoring stations in Sydney we used generalized additive model and CART analyses to profile the meteorological conditions influencing air quality during planned burns. The insights gained from this study will help improve prescribed burn scheduling in order to reduce the pollution risk to the community, while allowing fire agencies to conduct this important work.

Prescribing behavior of general practitioners: competition matters.

PubMed

Schaumans, Catherine

2015-04-01

General Practitioners (GP) have limited means to compete. As quality is hard to observe by patients, GPs have incentives to signal quality by using instruments patients perceive as quality. I investigate whether GPs prescribe more units when confronted with more competition. As there is no monetary benefit in doing so, this type of (perceived) quality competition originates from GPs satisfying patients' expectations. Market level data on per capita and per contact number of items prescribed by GPs is studied for the Belgian market of General Practitioners. I hypothesize that GP competition has a positive impact on the prescribed volume, after controlling for medical needs and GP characteristics. Properly controlling for medical needs implies the use of a two-stage linear regression model. The analysis indicates that a higher number of GPs per capita results in a higher number of units prescribed by GPs, both per capita and per contact. This is consistent with quality competition in the GP market, while inconsistent with alternatives explanations (GP scarcity, GP inducement and GP dispersing prescription in time). GPs prescribe more units when there is more competition to satisfy patients' expectations. The paper thus presents empirical evidence of (perceived) quality competition.

Challenges in health visitor prescribing in a London primary care trust.

PubMed

Thurtle, Val

2007-11-01

In this primary care trust there was limited health visitor prescribing. A case study approach sought to identify reasons for this, to lead to recommendations and changes to develop health visitor prescribing. The situation was examined using qualitative methods to consider the opportunities and challenges in health visitor prescribing. Semi-structured interviews with eighteen health visitors and managers explored their views of health visitor prescribing and its position within the PCT. The findings demonstrated only three health visitors prescribed; yet the majority were positive about prescribing, both for clients and health visitor development. Practitioners recognised their difficult working context and felt that organisational systems were not supportive of prescribing. A culture of prescribing was not felt to be in evidence, but was seen as a realistic possibility. Recommendations for change focused on the organisation and practitioners, with improved communication and structures supportive of prescribing. There was a need for practitioners to be active in learning so that they could share knowledge, experience and commitment to prescribing in locally based groups.

Importance Inappropriate antimicrobial prescribing leads to antimicrobial resistance and suboptimal clinical outcomes. Changing antimicrobial prescribing is a complex behavioral process that is not often taken into account in antimicrobial stewardship programs. Objective To examine whether an antimicrobial stewardship approach grounded in behavioral theory and focusing on preserving prescriber autonomy and participation is effective in improving appropriateness of antimicrobial prescribing in hospitals. Design, Setting, and Participants The Dutch Unique Method for Antimicrobial Stewardship (DUMAS) study was a prospective, stepped-wedge, participatory intervention study performed from October 1, 2011, through December 31, 2015. Outcomes were measured during a baseline period of 16 months and an intervention period of 12 months. The study was performed at 7 clinical departments (2 medical, 3 surgical, and 2 pediatric) in a tertiary care medical center and a general teaching hospital in the Netherlands. Physicians prescribing systemic antimicrobial drugs for any indication for patients admitted to the participating departments during the study period were included in the study. Interventions We offered prescribers a free choice of how to improve their antimicrobial prescribing. Prescribers were stimulated to choose interventions with higher potential for success based on a root cause analysis of inappropriate prescribing. Main Outcomes and Measures Appropriateness of antimicrobial prescriptions was determined using a validated approach based on guideline adherence and motivated guideline deviation and measured with repeated point prevalence surveys (6 per year). Appropriateness judgment was masked for the study period. Antimicrobial consumption was extracted from pharmacy records and measured as days of therapy per admission. We used linear and logistic mixed-model regression analysis to model outcomes over time. Results A total of 1121 patient cases with 700

Physicians face the choice of multiple ingredients when prescribing drugs in many therapeutic categories. For conditions with considerable patient heterogeneity in treatment response, customizing treatment to individual patient needs and preferences may improve outcomes. To assess variation in the diversity of antipsychotic prescribing for mental health conditions, a necessary although not sufficient condition for personalizing treatment. To identify patient caseload, physician, and organizational factors associated with the diversity of antipsychotic prescribing. Using 2011 data from Pennsylvania's Medicaid program, IMS Health's HCOSTM database, and the AMA Masterfile, we identified 764 psychiatrists who prescribed antipsychotics to 10 patients. We constructed three physician-level measures of diversity/concentration of antipsychotic prescribing: number of ingredients prescribed, share of prescriptions for most preferred ingredient, and Herfindahl-Hirschman index (HHI). We used multiple membership linear mixed models to examine patient caseload, physician, and healthcare organizational predictors of physician concentration of antipsychotic prescribing. There was substantial variability in antipsychotic prescribing concentration among psychiatrists, with number of ingredients ranging from 2-17, share for most preferred ingredient from 16%-85%, and HHI from 1,088-7,270. On average, psychiatrist prescribing behavior was relatively diversified; however, 11% of psychiatrists wrote an average of 55% of their prescriptions for their most preferred ingredient. Female prescribers and those with smaller shares of disabled or serious mental illness patients had more concentrated prescribing behavior on average. Antipsychotic prescribing by individual psychiatrists in a large state Medicaid program varied substantially across psychiatrists. Our findings illustrate the importance of understanding physicians' prescribing behavior and indicate that even among specialties

Rates of adult women receiving contraceptive provision when simultaneously prescribed a known teratogen are alarmingly low. The prevalence of this behavior among pediatric providers and their adolescent patients is unknown. The objective of this study was to describe pediatric provider behaviors for prescribing teratogens concurrently with counseling, referral, and/or prescribing of contraception (collectively called contraceptive provision) in the adolescent population. A retrospective review was conducted examining visits in 2008-2012 by adolescents aged 14 to 25 years in which a known teratogen (US Food and Drug Administration pregnancy risk category D or X) was prescribed. The electronic medical records were queried for demographic information, evidence of contraceptive provision, and menstrual and sexual histories. The data were analyzed using standard statistical methods. Within 4172 clinic visits, 1694 females received 4506 prescriptions for teratogenic medications. The most commonly prescribed teratogens were topiramate, methotrexate, diazepam, isotretinoin, and enalapril. The subspecialties prescribing teratogens most frequently were neurology, hematology-oncology, and dermatology. Overall, contraceptive provision was documented in 28.6% of the visits. Whites versus nonwhites and older versus younger girls were more likely to receive contraceptive provision. The presence of a federal risk mitigation system for the teratogen also increased the likelihood of contraceptive provision. Our data demonstrate female adolescents prescribed teratogens receive inadequate contraception provision, which could increase their risk for negative pregnancy outcomes. Although the presence of a federal risk mitigation system appears to improve contraceptive provision, these systems are costly and, in some instances, difficult to implement. Efforts to improve provider practices are needed. Copyright © 2016 by the American Academy of Pediatrics.

The mitosis-meiosis transition is essential for spermatogenesis. Specific and timely downregulation of the transcription factor DMRT1, and consequent induction of Stra8 expression, is required for this process in mammals, but the molecular mechanism has remained unclear. Here, we show that β-TrCP, the substrate recognition component of an E3 ubiquitin ligase complex, targets DMRT1 for degradation and thereby controls the mitosis-meiosis transition in mouse male germ cells. Conditional inactivation of β-TrCP2 in male germ cells of β-TrCP1 knockout mice resulted in sterility due to a lack of mature sperm. The β-TrCP-deficient male germ cells did not enter meiosis, but instead underwent apoptosis. The induction of Stra8 expression was also attenuated in association with the accumulation of DMRT1 at the Stra8 promoter in β-TrCP-deficient testes. DMRT1 contains a consensus β-TrCP degron sequence that was found to bind β-TrCP. Overexpression of β-TrCP induced the ubiquitylation and degradation of DMRT1. Heterozygous deletion of Dmrt1 in β-TrCP-deficient spermatogonia increased meiotic cells with a concomitant reduction of apoptosis. Collectively, our data indicate that β-TrCP regulates the transition from mitosis to meiosis in male germ cells by targeting DMRT1 for degradation. © 2017.

Influencing prescribing in English primary care: the views of primary care organisations.

Mason, Anne; Drummond, Michael; Towse, Adrian; Cooke, Jonathan

2004-07-01

The rapid rise of prescribing expenditure is a concern in many industrialised countries and methods to manage medicines are widely employed. The purpose of this study was to identify the approaches to improve primary care prescribing by primary care organisations (PCOs) in the National Health Service (NHS) in England. A questionnaire (Management of Medicines, MANMED) was mailed to prescribing advisers and prescribing leads in 332 PCOs. A response rate of 66% (220/332) was achieved. Most PCOs report the improvement of the quality of prescribing as their top priority, followed by budget adherence at both practice and PCO levels. Prescribing advisers typically offer several forms of support: practice visits, prescribing reviews, indicators of prescribing, prescribing newsletters, hands-on support, seminars and local formularies. PCOs are pursuing a wide range of prescribing initiatives, covering, on average, seven different therapeutic areas. National targets are the main driver for prescribing initiatives but other key influences include inappropriate prescribing and clinical governance. Although cost considerations are important, improving the quality of prescribing is perceived as the overriding principle on which PCO prescribing strategy is based. Multifaceted prescribing support is widespread and national targets are the largest single factor influencing choice of therapeutic area for prescribing initiatives. Diversity in approaches presents the opportunity to improve the evidence base for medicines management. Not only could such research inform PCOs in their central aim of improving the quality of prescribing within the NHS, but it may also offer insights of relevance to other countries if the influence of process and context upon the effectiveness of medicines management is systematically explored.

Financial incentives have been suggested to be effective in increasing the quality and efficiency of drug prescribing. Concern has been raised in relation to potential negative consequences on the quality of care. To describe and analyse the impact of an incentives model linking payment with adherence to drug and therapeutics committee (DTC) guidelines and self-reflection of prescribing pattern in a 'prescribing quality report'. The study was performed in the county of Stockholm, Sweden, with 139 (out of 154) primary healthcare centres (PHCs) participating in the project and 15 PHCs not participating. The study consisted of two parts: a quantitative observational study of prescribing patterns and a qualitative analysis of the submitted prescribing quality reports. All prescriptions issued from PHCs and dispensed at pharmacies during October to December 2005 and October to December 2006 were analysed, using adherence to the regional DTC guidelines as the main outcome measure. Adherence was assessed using the drug utilisation 90% methodology, i.e. focusing on drugs constituting 90% of the prescribed volume and the proportion of drugs included in the guidelines. The qualitative analysis focused on reports on the quality of drug prescribing submitted by each PHC in early 2007. The 139 PHCs participating in the programme accounted for 85% of all prescriptions issued in primary care during October to December 2006. Mean adherence to guidelines increased among participating practices by 3.3 percentage units (95% confidence interval (CI) 2.9-3.7%) to 83% (82.6-83.7%) during the year. The adherence among practices not participating increased by 3.1 percentage units (95% CI 1.7-4.4%) to 78.8% (95% CI 76.7-80.9%). The higher adherence achieved during the year corresponded to savings estimated at five times greater than the cost of running the programme including the financial incentives. In addition, many areas for improving prescribing were identified, such as limiting the

Prescribing without evidence – pregnancy

PubMed Central

Thomas, Simon H L; Yates, Laura M

2012-01-01

Prescribing of medicines during pregnancy is common, and for some groups of women is essential for maintaining maternal and therefore fetal health. Pregnant women and prescribers are rightly concerned, however, about the potential adverse fetal effects of medicines. These may include fetal death or stillbirth, congenital malformations, developmental impairment, neonatal effects or late carcinogenesis. It is therefore essential that the risks and benefits for mother and fetus are considered carefully before prescribing in pregnancy. This is often challenging because of the paucity of information available. To complicate the issue further, drug pharmacokinetics are commonly altered in pregnancy, potentially affecting optimal dosing as well as interpretation of plasma concentration measurements, with specific information on individual drugs seldom available. Most drugs cross the placenta, especially lipophilic drugs and those with low plasma protein binding. Active membrane transporters also have an important role in enhancing or preventing drug transfer, although this is not yet clearly understood. Animal studies have limited applicability to humans because of species-specific effects, and clinical trials in pregnancy are only undertaken in special circumstances. Prescribers therefore need to rely on observational studies of fetal outcomes following drug exposure in human pregnancy. These often involve limited numbers, and data are also subject to confounding and bias, making interpretation difficult. It therefore remains essential that appropriate mechanisms for systematic data collection, including congenital malformation registries, teratology information services, pregnancy registers and linked population registries, are maintained and enhanced to increase the amount and quality of information available.

OGLE-TR-113-b is a giant exoplanet that was discovered independently by Bouchy et al. (2004, A&A, 421, L13), and by Konacki et al. (2004, ApJ, 609, L37). We present high quality near-IR and optical data during the transit of this planet in front of the star OGLE-TR-113 (V=14.42, α =10:52:24.4 and δ =-61:26:48.5). The K-band observations were obtained in May 2005 with SOFI+NTT, located at ESO La Silla (Chile), and the V-band observations were obtained in April 2005 with VIMOS+VLT, located at ESO Paranal (Chile). After the data reduction process and difference image photometry, it was possible to achieve millimagnitude precision for the transit light curves in both bands. The planetary transit is clearly seen for the first time in the K-band, with similar amplitudes A = 0.03 mag in both V, I, and K, confirming the planetary size of the OGLE-TR-113 companion. Our monitoring program for this and other OGLE transit candidates using accurate optical and near-IR photometry allows us to discard false positives (binaries, blends, giants, etc), and to refine the star/planet parameters.

We systematically design materials using topology optimization to achieve prescribed nonlinear properties under finite deformation. Instead of a formal homogenization procedure, a numerical experiment is proposed to evaluate the material performance in longitudinal and transverse tensile tests under finite deformation, i.e. stress-strain relations and Poissons ratio. By minimizing errors between actual and prescribed properties, materials are tailored to achieve the target. Both two dimensional (2D) truss-based and continuum materials are designed with various prescribed nonlinear properties. The numerical examples illustrate optimized materials with rubber-like behavior and also optimized materials with extreme strain-independent Poissons ratio for axial strain intervals of εi∈[0.00, 0.30].

Audits of antibiotic prescribing in a Bristol hospital.

1983-01-01

Audits of antibiotic prescribing were done for periods of up to eight weeks in two successive years on medical, surgical, orthopaedic, gynaecology, obstetric, and urology wards and in an accident and emergency department. Clinical details were matched with antibiotic prescribing, and the appropriateness of the latter was judged independently by two medical microbiologists. Only when they agreed was an individual prescription included in the analysis. Overall, 28% of prescriptions in 1979 and 35% in 1980 were judged as unnecessary, with 17% and 16%, respectively, being for inappropriate choices of antibiotic. An educational programme about antibiotic prescribing carried out between the audits had no beneficial effect overall. Though the results compared favourably with those of audits published, prescribing could still be much improved. To judge by the failure of education, however, this might be difficult to achieve. Most prescriptions were written by junior staff, who in the absence of guidance from their seniors and because of their frequent moves would require a widespread and continual education programme. Published concern about the quality of antibiotic prescribing appears to be justified. PMID:6401484

Background There is a lack of large comprehensive studies in developing countries on paediatric in-patient prescribing errors in different settings. Objectives To determine the characteristics of in-patient prescribing errors among paediatric patients. Setting General paediatric wards, neonatal intensive care units and paediatric intensive care units in government hospitals in Malaysia. Methods This is a cross-sectional multicentre study involving 17 participating hospitals. Drug charts were reviewed in each ward to identify the prescribing errors. All prescribing errors identified were further assessed for their potential clinical consequences, likely causes and contributing factors. Main outcome measures Incidence, types, potential clinical consequences, causes and contributing factors of the prescribing errors. Results The overall prescribing error rate was 9.2% out of 17,889 prescribed medications. There was no significant difference in the prescribing error rates between different types of hospitals or wards. The use of electronic prescribing had a higher prescribing error rate than manual prescribing (16.9 vs 8.2%, p < 0.05). Twenty eight (1.7%) prescribing errors were deemed to have serious potential clinical consequences and 2 (0.1%) were judged to be potentially fatal. Most of the errors were attributed to human factors, i.e. performance or knowledge deficit. The most common contributing factors were due to lack of supervision or of knowledge. Conclusions Although electronic prescribing may potentially improve safety, it may conversely cause prescribing errors due to suboptimal interfaces and cumbersome work processes. Junior doctors need specific training in paediatric prescribing and close supervision to reduce prescribing errors in paediatric in-patients.

To evaluate the impact of generic substitution decision support on electronic (e-) prescribing of generic medications. The authors analyzed retrospective outpatient e-prescribing data from an academic medical center and affiliated network for July 1, 2005-September 30, 2008 using an interrupted time-series design to assess the rate of generic prescribing before and after implementing generic substitution decision support. To assess background secular trends, e-prescribing was compared with a concurrent random sample of hand-generated prescriptions. Proportion of generic medications prescribed before and after the intervention, evaluated over time, and compared with a sample of prescriptions generated without e-prescribing. The proportion of generic medication prescriptions increased from 32.1% to 54.2% after the intervention (22.1% increase, 95% CI 21.9% to 22.3%), with no diminution in magnitude of improvement post-intervention. In the concurrent control group, increases in proportion of generic prescriptions (29.3% to 31.4% to 37.4% in the pre-intervention, post-intervention, and end-of-study periods, respectively) were not commensurate with the intervention. There was a larger change in generic prescribing rates among authorized prescribers (24.6%) than nurses (18.5%; adjusted OR 1.38, 95% CI 1.17 to 1.63). Two years after the intervention, the proportion of generic prescribing remained significantly higher for e-prescriptions (58.1%; 95% CI 57.5% to 58.7%) than for hand-generated prescriptions ordered at the same time (37.4%; 95% CI 34.9% to 39.9%) (p<0.0001). Generic prescribing increased significantly in every specialty. Implementation of generic substitution decision support was associated with dramatic and sustained improvements in the rate of outpatient generic e-prescribing across all specialties.

Aims Prescribing errors are common and inadequate preparation of prescribers appears to contribute. A junior doctor-led prescribing tutorial programme has been developed for Edinburgh final year medical students to increase exposure to common prescribing tasks. The aim of this study was to assess the impact of these tutorials on students and tutors. Methods One hundred and ninety-six tutorials were delivered to 183 students during 2010–2011. Each student completed a questionnaire after tutorial attendance which explored their previous prescribing experiences and the perceived benefits of tutorial attendance. Tutors completed a questionnaire which evaluated their teaching experiences and the impact on their prescribing practice. Student tutorial attendance was compared with end-of-year examination performance using linear regression analysis. Results The students reported increased confidence in their prescribing knowledge and skills after attending tutorials. Students who attended more tutorials also tended to perform better in end-of-year examinations (Drug prescribing: r = 0.16, P = 0.015; Fluid prescribing: r = 0.18, P = 0.007). Tutors considered that participation enhanced their own prescribing knowledge and skills. Although they were occasionally unable to address student uncertainties, 80% of tutors reported frequently correcting misconceptions and deficits in student knowledge. Ninety-five percent of students expressed a preference for prescribing training delivered by junior doctors over more senior doctors. Conclusions A ‘near-peer’ junior doctor-led approach to delivering prescribing training to medical students was highly valued by both students and tutors. Although junior doctors have relatively less clinical experience of prescribing, we believe that this can be addressed by training and academic supervision and is outweighed by the benefits of these tutorials.

Nurse prescribing ethics and medical marketing.

PubMed

Adams, J

This article suggests that nurse prescribers require an awareness of key concepts in ethics, such as deontology and utilitarianism to reflect on current debates and contribute to them. The principles of biomedical ethics have also been influential in the development of professional codes of conduct. Attention is drawn to the importance of the Association of the British Pharmaceutical Industry's code of practice for the pharmaceutical industry in regulating marketing aimed at prescribers.

Background Physicians face the choice of multiple ingredients when prescribing drugs in many therapeutic categories. For conditions with considerable patient heterogeneity in treatment response, customizing treatment to individual patient needs and preferences may improve outcomes. Aims of the Study To assess variation in the diversity of antipsychotic prescribing for mental health conditions, a necessary although not sufficient condition for personalizing treatment. To identify patient caseload, physician, and organizational factors associated with the diversity of antipsychotic prescribing. Methods Using 2011 data from Pennsylvania’s Medicaid program, IMS Health’s HCOS™ database, and the AMA Masterfile, we identified 764 psychiatrists who prescribed antipsychotics to ≥10 patients. We constructed three physician-level measures of diversity/concentration of antipsychotic prescribing: number of ingredients prescribed, share of prescriptions for most preferred ingredient, and Herfindahl-Hirschman index (HHI). We used multiple membership linear mixed models to examine patient caseload, physician, and healthcare organizational predictors of physician concentration of antipsychotic prescribing. Results There was substantial variability in antipsychotic prescribing concentration among psychiatrists, with number of ingredients ranging from 2-17, share for most preferred ingredient from 16%-85%, and HHI from 1,088-7,270. On average, psychiatrist prescribing behavior was relatively diversified; however, 11% of psychiatrists wrote an average of 55% of their prescriptions for their most preferred ingredient. Female prescribers and those with smaller shares of disabled or serious mental illness patients had more concentrated prescribing behavior on average. Discussion Antipsychotic prescribing by individual psychiatrists in a large state Medicaid program varied substantially across psychiatrists. Our findings illustrate the importance of understanding physicians�

Nurse prescriber-patient consultations: a case study in dermatology.

This paper is a report of a study exploring the content and processes in consultations between nurse prescribers and patients with dermatological conditions. Communication skills, consultation time, information and follow-up are central to the treatment and management of patients with dermatological conditions. The contribution nurses make to the care of these patients has great potential. A multiple case study was conducted with 10 practice settings across England in which nurses prescribed medicines for patients with dermatological conditions. Data were collected between June 2006 and September 2007 using semi-structured interviews (n = 40), patient questionnaires (n = 165/200) and videotaped observations of nurse consultations (n = 40). Data analysis included thematic analysis, descriptive statistics, chi-square and non-parametric tests. Nurses believed that their holistic approach to assessment, combined with their prescribing knowledge, improved prescribing decisions. Listening and explanation of treatments were aspects of nurse communication that were rated highly by patients. Listening and dealing sensitively with emotions were also aspects of the videotaped consultations that were rated highly by assessors. Nurses were less consistent in providing information about medicines. Triangulated data from this study suggest that nurse prescribing enhances the care of patients with dermatological conditions through improved prescribing decisions. If patients are to be more involved in this decision-making, nurses must give them more information about their medicines. The benefits of prescribing were most evident in the practices of dermatology specialist nurses. Further evidence is required to identify whether prescribing by specialist nurses offers similar benefits in other therapeutic areas.

Estimates of geographic variation among states and counties in the prevalence of opioid prescribing are developed using data from a large (135M) representative national sample of opioid prescriptions dispensed during 2008 by 37,000 retail pharmacies. Statistical analyses are used to estimate the extent to which county variation is explained by characteristics of resident populations, their healthcare utilization, proxy measures of morbidity, availability of healthcare resources, and prescription monitoring laws. Geographic variation in prevalence of prescribed opioids is large, greater than variation observed for other healthcare services. Counties having the highest prescribing rates for opioids were disproportionately located in Appalachia and in Southern and Western states. The number of available physicians was by far the strongest predictor of amounts prescribed, but only one-third of county variation is explained by the combination of all measured factors. Wide variation in prescribing opioids reflects weak consensus regarding the appropriate use of opioids for treating pain, especially chronic non-cancer pain. Patients’ demands for treatment have increased, more potent opioids have become available, an epidemic of abuse has emerged, and calls for increased government regulation are growing. Greater guidance, education and training in opioid prescribing are needed for clinicians to support appropriate prescribing practices. Perspective Wide geographic variation that does not reflect differences in the prevalence of injuries, surgeries, or conditions requiring analgesics raises questions about opioid prescribing practices. Low prescription rates may indicate under-treatment, while high rates may indicate overprescribing and insufficient attention to risks of misuse. PMID:23031398

Short-term medical missions (STMMs) have increased and are viewed as a way to extend care in low- and middle-income countries (LMICs). Although benefits may exist, visiting teams may lack insight into using medications safely and effectively. The primary objective was to assess prescribing differences between US-based and Dominican Republic (DR) healthcare providers on STMMs in the DR. A retrospective database review between January 2013 and 2015 was conducted. Data from US and DR groups were compared for differences in diagnoses, medication classes prescribed and prescriptions per patient. The mean number of medical conditions diagnosed per patient in the DR (n=423) and US groups (n=1585) were 1.4±0.9 and 1.0±0.8, respectively. The diagnosis of infectious diseases was the same as non-communicable diseases. The DR group prescribed more medications at each patient encounter (mean 2.6 vs 2.2, respectively; p<0.001). The US group prescribed more antibiotics for respiratory infections (US 46.2% vs DR 25.0%; p=0.0001), used more metronidazole than albendazole alone for parasite infections (p=0.0022) and used more oral fluconazole for vaginal candidiasis (p<0.0001) and tinea infections (US 44.6%, DR 14.3%, respectively; p=0.0020). Although some significant prescribing differences exist between US and DR providers, many similarities were present. Visiting providers should understand the medication use system and disease burden before providing care in an LMIC. © The Author 2017.

Antimicrobial stewardship (AMS) programmes have been developed with the intention of reducing inappropriate and unnecessary use of antimicrobials, while improving the quality of patient care and locally helping prevent the development of antimicrobial resistance. An important aspect of AMS programmes is the qualitative assessment of prescribing through antimicrobial prescribing surveys (APS), which are able to provide information about the prescribing behaviour within institutions. Owing to lack of standardization of audit tools and the resources required, qualitative methods for the assessment of antimicrobial use are not often performed. The aim of this study was to design an audit tool that was appropriate for use in all Australian hospitals, suited to local user requirements and included an assessment of the overall appropriateness of the prescription. In November 2011, a pilot APS was conducted across 32 hospitals to assess the usability and generalizability of a newly designed audit tool. Following participant feedback, this tool was revised to reflect the requirements of the respondents. A second pilot study was then performed in November 2012 across 85 hospitals. These surveys identified several areas that can be targets for quality improvement at a national level, including: documentation of indication; surgical prophylaxis prescribed for >24 h; compliance with prescribing guidelines; and the appropriateness of the prescription. By involving the end users in the design and evaluation, we have been able to provide a practical and relevant APS tool for quantitative and qualitative data collection in a wide range of Australian hospital settings. © The Author 2015.

1998-09-01

The occultation of the star Tr176 by Triton (Mc Donald & Elliot, AJ 109, 1352, 1995) was observed on 18 July 1997 from three stations in Queensland, Australia (Bundaberg, Ducabrook and Lochington) and one station in Texas, USA (Brownsville). All observations were made with CCD (no filter) and with portable C14 telescopes, except at Bundaberg, where a fixed 48-cm telescope was used. Time sampling rate ranges from 0.33 sec (Bundaberg) to 0.66 sec (Ducabrook and Lochington), with the intermediate value 0.5 sec at Brownsville. Isothermal fits were performed to the lightcurves in order to determine the isothermal temperature, T_iso, and the radius at half-level, R_{1/2}, of Triton's atmosphere (assumed to be composed of pure N_2). Considering the level of noise, we cannot detect any departure from isothermal profiles, and we do not see any deviations from spherical shape. A global fit yields T_iso = 53.7 +/- 2 K and R_{1/2} = 1456 +/- 3 km. We also derive the pressure at 1400 km: p1400 = 1.9 +/- 0.3 mu bars. We will discuss these results and compare them with previous works obtained by Voyager teams from the 1989 observations, and by Olkin et al. (Icarus 129, 178, 1997), who analyze two Triton occultations observed in July 1993 (Tr60) and August 1995 (Tr148). We observe a general increase of pressure at 1400 km, since Olkin et al. derive p1400 = 1.4 +/- 0.1 mu bars from the Tr148 event. This result is actually confirmed by a recent work by Elliot et al., (Nature 393, 765 1998), who note a global warming on Triton, based in particular on a new HST occultation observation in November 1997 (Tr180).

Aim To identify experience with and attitudes towards paediatric off-label prescribing in primary care. Method A prospective questionnaire survey was sent to a sample of Scottish primary care practices (346 doctors in 80 general practices located throughout Scotland). Results Two hundred and two (58%) completed questionnaires were returned. Over 70% of GPs admitted to being familiar with the concept, and 40% to knowingly prescribing off-label. The most important sources of paediatric prescribing information were the British National Formulary (81%), personal experience (71%) and previous prescription notes (45%). The most common reason given by GPs for off-label prescribing was prescribing for a younger age than recommended, although prescribing data confirm that age is the least important and dose the most important reason for such prescribing. When asked to comment upon different causes for off-label prescribing, 80% of respondents expressed appropriate awareness of and concern for the described scenarios. Over 97% of GPs ranked development of paediatric formulations and clearer dosage information more highly than clinical trials as a means to reducing off-label prescribing. Conclusions Despite high levels of off-label prescribing in primary care in the UK, the majority of GPs claimed to be familiar with the concept, although less than half were aware of this common practice. A clear disparity between perceived and actual reasons for off-label prescribing was noted, possibly due to a reliance on personal experience, colleague experience or previous patient prescription notes as a guide to prescribing.

Drug-drug interactions (DDIs) are common in clinical care and pose serious risks for patients. Electronic health records display DDI alerts that can influence prescribers, but the interface design of DDI alerts has largely been unstudied. In this study, the objective was to apply human factors engineering principles to alert design. It was hypothesized that redesigned DDI alerts would significantly improve prescribers' efficiency and reduce prescribing errors. In a counterbalanced, crossover study with prescribers, two DDI alert designs were evaluated. Department of Veterans Affairs (VA) prescribers were video recorded as they completed fictitious patient scenarios, which included DDI alerts of varying severity. Efficiency was measured from time-stamped recordings. Prescribing errors were evaluated against predefined criteria. Efficiency and prescribing errors were analyzed with the Wilcoxon signed-rank test. Other usability data were collected on the adequacy of alert content, prescribers' use of the DDI monograph, and alert navigation. Twenty prescribers completed patient scenarios for both designs. Prescribers resolved redesigned alerts in about half the time (redesign: 52 seconds versus original design: 97 seconds; p<.001). Prescribing errors were not significantly different between the two designs. Usability results indicate that DDI alerts might be enhanced by facilitating easier access to laboratory data and dosing information and by allowing prescribers to cancel either interacting medication directly from the alert. Results also suggest that neither design provided adequate information for decision making via the primary interface. Applying human factors principles to DDI alerts improved overall efficiency. Aspects of DDI alert design that could be further enhanced prior to implementation were also identified.

The road to pharmacist prescribing in Alberta Health Services.

The implementation of policy within a health organization to support a new legislative and regulatory framework of pharmacist prescribing in the Canadian province of Alberta is described. The evolution of pharmacists' practice activities to encompass medication management through independent prescribing authority has occurred in many jurisdictions around the world. In 2007, Alberta pharmacists were granted the most progressive scope of practice in all of North America. Pursuant to a series of legislative and regulatory initiatives enacted since 2000, the provincial health authority, Alberta Health Services (AHS), has worked to (1) establish a policy framework that supports pharmacist prescribing, (2) provide opportunities for pharmacist prescribing in both inpatient and ambulatory care practice environments, and (3) provide motivation and resources for AHS pharmacists to acquire "additional prescribing authorization" (APA) that enables them to independently prescribe and manage patients' ongoing drug therapy. Pharmacists with APA currently are permitted to prescribe all medications requiring a prescription, with the exception of opiates and other controlled substances; efforts to expand pharmacist prescribing to include those medications are ongoing. Currently, nearly half of all AHS pharmacists have APA. The health authority plans to make APA a standard expectation for all clinical pharmacists working in collaborative practice settings. Opportunities provided to Alberta pharmacists by legislation have been embraced by the provincial health authority. The AHS leadership remains committed to ensuring that its pharmacists practice to the full extent of their scope of practice and actively encourages and supports them in their efforts to provide optimal patient care.

There is evidence of inappropriate medication use, causing unnecessary costs for health systems, particularly those with limited resources. Overprescription is commonly reported and can lead to antibiotic resistance. Prescribing patterns differ between countries; little is known about paediatric prescribing practices in Africa. To investigate prescribing practices in children in The Gambia, West Africa. A retrospective survey of prescribing practices in children under 5 years of age based on WHO protocol DAP/93.1 was conducted. Twenty government-run health centres across all six regions in The Gambia were assessed. The first 10 encounters each month in 2010 were recorded. For each encounter, patient demographics, diagnoses and medications were recorded as per protocol. Two thousand and four hundred patient encounters were included. The mean number of medications per encounter was 2.2 (median 2.0, IQR 2.0-3.0). Across different geographical regions within The Gambia antibiotics were prescribed in 63.4% (IQR 62.8-65.8%) and micronutrients in 21.7% (IQR 15.3-27.1%) of patient encounters. There was evidence of high antibiotic prescription in children with cough and coryzal symptoms (54.5%; IQR 35.8-59.0%) and simple diarrhoea without dehydration (44.8%; IQR 36.7-61.3%). 74.8% (IQR 71.8-76.1%) of medications were prescribed generically. The study showed an overprescription of antibiotics and substantial usage of micronutrients despite a lack of international evidence-based guidelines. Cost-effective interventions to improve prescribing practices are called for and more studies with a focus on rational prescribing in paediatrics in low-income settings are urgently required to fill the gap in current knowledge.

Abstract Sorafenib is the only Food and Drug Administration (FDA)-approved first-line therapy shown to have survival benefit for patients with advanced hepatocellular carcinoma (HCC). Patients with advanced HCC are often but not exclusively transferred from non-oncologists to oncologists to initiate systemic therapy. The objective of this study was to assess whether sorafenib prescribing by non-oncologists has any impact on utilization, adverse effects, cost or outcome. This was a retrospective cohort study utilizing data from patients prescribed sorafenib for HCC within Veterans Health Administration hospitals with 100% chart abstraction to confirm HCC diagnosis, identify prescribing provider specialty (oncology versus gastroenterology/hepatology), and obtain data required for cancer staging by the Barcelona Clinic Liver Cancer (BCLC) system. The primary outcome was overall survival from the time of sorafenib prescription. A total of 4903 patients who prescribed sorafenib for HCC were identified, for whom 340 patients (6.9%) were prescribed drug by a non-oncologist (Onc). BCLC Stage, age, Child–Turcotte–Pugh score, and comorbidity indices were similar between patients prescribed sorafenib by oncologists and non-oncologists. Oncologists more often discontinued sorafenib due to progression, whereas non-oncologists were more likely to continue sorafenib until death resulting in greater pill utilization and cost. Overall survival in both unadjusted and multivariable models showed no significant impact of prescriber type on survival (222 vs 217 days, P = .96), confirmed with propensity-matched subcohorts. Similar survival outcomes were observed for patients with HCC prescribed sorafenib by non-oncologists and oncologists, suggesting that non-oncologists with expertise in the management of HCC can safely and effectively administer sorafenib.

A review of the factors influencing antimicrobial prescribing.

Calbo, Esther; Alvarez-Rocha, Luis; Gudiol, Francisco; Pasquau, Juan

2013-09-01

There are multiple benefits of appropriate antimicrobial prescribing: it has a direct impact on clinical outcomes, avoids adverse effects, is cost effective and, perhaps most importantly, it helps to prevent the emergence of resistance. However, any physician can prescribe antibiotics, which is not the case with other clinically relevant drugs. There is great variability in the prescribing physician's (PP) training, motivation, workload and setting, including accessibility to infectious diseases consultants and/or diagnostic techniques, and therefore there is a high risk of inappropriate prescription. Many antibiotic prescribing errors occur around the selection and duration of treatment. This includes a low threshold for the indication of antibiotics, delayed initiation of treatment when indicated, limited knowledge of local antimicrobial resistance patterns by the PPs, errors in the final choice of dose, route or drug and a lack of de-escalation. Similarly, the prescription of prophylactic antibiotics to prevent surgical site infections, despite being commonly accepted, is suboptimal. Factors that may explain suboptimal use are related to the absence of well-defined protocols, poor knowledge of prophylactic protocols, miscommunication or disagreement between physicians, logistical problems, and a lack of audits. A proper understanding of the prescribing process can guide interventions to improve the PP's practices. Some of the potential interventions included in a stewardship program are education in antimicrobial prescribing, information on the local resistance patterns and accessibility to a qualified infectious diseases consultant.

2008-09-01

To determine whether drug samples are associated with physicians prescribing fewer generic, less costly medications. We conducted a retrospective study at a large university-affiliated internal medicine practice containing over 70 physicians. Using a pharmacy database, we identified all prescriptions written to uninsured or Medicaid patients that belonged to one of four classes of chronic medications. For the 9 months before and after the clinic closed its drug sample closet, we calculated the percentage of medications prescribed as generics and the mean cost of a 30-day supply of a prescription. Of 8911 prescriptions, 1973 met inclusion criteria. For uninsured patients, the percentage of medications prescribed as generics rose from 12% to 30% after the clinic closed its drug sample closet (P = 0.004). By consecutive three month periods, the percentage of prescribed generic medications rose steadily to a maximum of 40% (P < 0.001). For Medicaid patients, there was no significant change in generic prescribing (63% generic with samples versus 65% generic without samples, P = 0.42). Two factors were associated with generic prescribing in logistic regression: the absence of drug samples (OR 4.54, 95% CI 1.37-15.0) and the prescriber being an attending physician (OR 5.26, 95% CI 2.24-12.4). There was no statistically significant change in cost for either group. Physicians were three times more likely to prescribe generic medications to uninsured patients after drug samples were removed from the office. Drug samples may paradoxically lead to higher costs if physicians with access to samples prescribe more brand-name only drugs.

The objective of this study is to survey general prescribing behaviour by Belgian companion animal veterinarians and to assess agreement of these practices with current treatment guidelines. Therefore an online survey was administered with five realistic and frequently occurring first-line cases to primary-care veterinary practitioners. For each case a predefined pattern of questions were asked about whether or not they would prescribe antimicrobials, if they would prescribe a non-antimicrobial treatment and if they would perform additional diagnostic steps. The responses were compared with recommendations in national guidelines and recent literature. The overall most prescribed antimicrobials were potentiated amoxicillin (43.0 per cent), fluoroquinolones (14.7 per cent), third-generation and fourth-generation cephalosporins (10.9 per cent) and tetracyclines (10.9 per cent). Only 48.3 per cent of the veterinarians complied with the guidelines in nearly all of the clinical scenarios (ie, prescribing antimicrobials when indicated, not prescribing antimicrobials when it is not indicated). Moreover, when prescribing highest priority critically important antimicrobials, susceptibility testing on bacterial cultures was performed in only 12.4 per cent of the prescriptions. The results showed that the prescribing behaviour of antimicrobial compounds by primary-care veterinary practitioners in dogs and cats is often not in agreement with national guidelines. Focus in improvement of this prescribing behaviour should be on performing the appropriate diagnostic steps and decreasing the use of highest priority critically important antimicrobials. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

Background Electronic prescribing system implementation is recommended to improve patient safety and general practitioner's discharge information communication. There is a paucity of information about hospital staff perspectives before and after system implementation. Objective To explore hospital staff views regarding prescribing and discharge communication systems before and after hospital electronic prescribing and medicines administration (HEPMA) system implementation. Setting A 560 bed United Kingdom district general hospital. Methods Semi-structured face-to-face qualitative interviews with a purposive sample of hospital staff involved in the prescribing and discharge communication process. Interviews transcribed verbatim and coded using the Framework Approach. Behavioural aspects mapped to Theoretical Domains Framework (TDF) to highlight associated behavioural change determinants. Main outcome measure Staff perceptions before and after implementation. Results Nineteen hospital staff (consultant doctors, junior doctors, pharmacists and advanced nurse practitioners) participated before and after implementation. Pre-implementation main themes were inpatient chart and discharge letter design and discharge communication process with issues of illegible and inaccurate information. Improved safety was anticipated after implementation. Post-implementation themes were improved inpatient chart clarity and discharge letter quality. TDF domains relevant to staff behavioural determinants preimplementation were knowledge (task or environment); skills (competence); social/professional roles and identity; beliefs about capabilities; environmental context and resources (including incidents). An additional two were relevant post-implementation: social influences and behavioural regulation (including self-monitoring). Participants described challenges and patient safety concerns pre-implementation which were mostly resolved post-implementation. Conclusion HEPMA implementation

Potentially inappropriate prescribing (PIP) is common in older people in primary care, as evidenced by a significant body of quantitative research. However, relatively few qualitative studies have investigated the phenomenon of PIP and its underlying processes from the perspective of general practitioners (GPs). The aim of this paper is to explore qualitatively, GP perspectives regarding prescribing and PIP in older primary care patients. Semi-structured qualitative interviews were conducted with GPs participating in a randomised controlled trial (RCT) of an intervention to decrease PIP in older patients (≥70 years) in Ireland. Interviews were conducted with GP participants (both intervention and control) from the OPTI-SCRIPT cluster RCT as part of the trial process evaluation between January and July 2013. Interviews were conducted by one interviewer and audio recorded. Interviews were transcribed verbatim and a thematic analysis was conducted. Seventeen semi-structured interviews were conducted (13 male; 4 female). Three main, inter-related themes emerged (complex prescribing environment, paternalistic doctor-patient relationship, and relevance of PIP concept). Patient complexity (e.g. polypharmacy, multimorbidity), as well as prescriber complexity (e.g. multiple prescribers, poor communication, restricted autonomy) were all identified as factors contributing to a complex prescribing environment where PIP could occur, as was a paternalistic-doctor patient relationship. The concept of PIP was perceived to be of variable usefulness to GPs and the criteria to measure it may be at odds with the complex processes of prescribing for this patient population. Several inter-related factors contributing to the occurrence of PIP were identified, some of which may be amenable to intervention. Improvement strategies focused on improved management of polypharmacy and multimorbidity, and communication across primary and secondary care could result in substantial improvements

Benefits of nurse prescribing for patients in pain: nurses' views.

PubMed

Stenner, Karen; Courtenay, Molly

2008-07-01

This paper is a report of a study to explore nurses' views on the benefits of adopting the role of prescribing for patients with acute and chronic pain. It was envisioned that the advent of nurse prescribing would be beneficial to the efficiency and effectiveness of the United Kingdom National Health Service. Research to date does indeed indicate that nurse prescribing can be beneficial to patients, nurses and the health service in general. Despite the expansion of nurse prescribing, there is little evidence of its impact according to nurses working in specialist areas, such as with patients in acute and chronic pain. Interviews were conducted during 2006 and 2007 with 26 nurses qualified to prescribe medicines for patients in acute and chronic pain. This was a qualitative study and a thematic analysis was conducted. Nurses reported a number of benefits, including faster access to treatment, improved quality of care, more appropriate prescribing of medication, improved safety, improved relations and communication with patients, greater efficiency and cost effectiveness. Nurses benefited from increased job satisfaction, credibility with patients and healthcare professionals and also gained knowledge through prescribing. There is potential for the benefits of nurse prescribing to be expanded beyond the United Kingdom in settings where nurses hold similar roles in the treatment of pain, although further research using a wider range of research methods is recommended to substantiate these findings.

2013-02-10

The Apache Point Survey of Transit Lightcurves of Exoplanets (APOSTLE) observed 11 transits of TrES-3b over two years in order to constrain system parameters and look for transit timing and depth variations. We describe an updated analysis protocol for APOSTLE data, including the reduction pipeline, transit model, and Markov Chain Monte Carlo analyzer. Our estimates of the system parameters for TrES-3b are consistent with previous estimates to within the 2{sigma} confidence level. We improved the errors (by 10%-30%) on system parameters such as the orbital inclination (i {sub orb}), impact parameter (b), and stellar density ({rho}{sub *}) compared to previousmore » measurements. The near-grazing nature of the system, and incomplete sampling of some transits, limited our ability to place reliable uncertainties on individual transit depths and hence we do not report strong evidence for variability. Our analysis of the transit timing data shows no evidence for transit timing variations and our timing measurements are able to rule out super-Earth and gas giant companions in low-order mean motion resonance with TrES-3b.« less

Improved fabrication of focused single element P(VDF–TrFE) transducer for high frequency ultrasound applications

PubMed Central

Jeong, Jong Seob; Shung, K. Kirk

2013-01-01

We present an improved fabrication technique for the focused single element poly (vinylidene fluoride–trifluoroethylene) P(VDF–TrFE) transducer. In this work, a conductive epoxy for a backing layer was directly bonded to the 25 μm thick P(VDF–TrFE) film and thus made it easy to conform the aperture of the P(VDF–TrFE) transducer. Two prototype focused P(VDF–TrFE) transducers with disk- and ring-type aperture were fabricated and their performance was evaluated using the UBM (Ultrasound Biomicroscopy) system with a wire phantom. All transducers had a spherically focused aperture with a low f-number (focal depth/aperture size = 1). The center frequency of the disk-type P(VDF–TrFE) transducer was 23 MHz and −6 dB bandwidth was 102%. The ring-type P(VDF–TrFE) transducer had 20 MHz center frequency and −6 dB bandwidth of 103%. The measured pulse echo signal had reduced reverberation due to no additional adhesive layer between the P(VDF–TrFE) film and the backing layer. Hence, the proposed method is promising to fabricate a single element transducer using P(VDF–TrFE) film for high frequency applications. PMID:23021238

Prescribed burning to restore grasslands is more complicated than just setting a fire or, worse, letting a fire burn. We will examine how fire may be used to restore a more desirable landscape. First, any area that might be considered for prescribed fire should be thoroughly evaluated. Soils are paramount as they will indicate what we can expect from a given site. Then...

Electronic prescribing in pediatrics: toward safer and more effective medication management.

Johnson, Kevin B; Lehmann, Christoph U

2013-04-01

This technical report discusses recent advances in electronic prescribing (e-prescribing) systems, including the evidence base supporting their limitations and potential benefits. Specifically, this report acknowledges that there are limited but positive pediatric data supporting the role of e-prescribing in mitigating medication errors, improving communication with dispensing pharmacists, and improving medication adherence. On the basis of these data and on the basis of federal statutes that provide incentives for the use of e-prescribing systems, the American Academy of Pediatrics recommends the adoption of e-prescribing systems with pediatric functionality. This report supports the accompanying policy statement from the American Academy of Pediatrics recommending the adoption of e-prescribing by pediatric health care providers.

Little is known about the prevalence of opioid shoppers in clinical practices and the relation between prescriber characteristics and the risk of having opioid shoppers. Describe the prevalence of opioid shoppers in prescribers' practices. Assess the relation between prescribers' characteristics and patient opioid shopping behavior. Retrospective cohort study using a large US retail prescription database. Patients with ≥1 opioid dispensing were followed 18 months. These patients' prescribers are the focus of the study. A patient was a "shopper" if he or she had opioid prescriptions written by ≥1 prescriber with ≥1 day of overlap filled at ≥3 pharmacies and a "heavy shopper" if he or she had ≥5 shopping episodes. The proportions of shoppers by prescriber and the proportion of prescribers with ≥1 shopper or heavy shopper were calculated. Among 858,290 opioid prescribers, most (87 percent) had no shoppers and 98 percent had no heavy shoppers. Prescribers who were aged 70-79 years, male, or who prescribed schedule II opioids had an increased likelihood of having shoppers. As the number of patients for whom a prescriber prescribed opioids increased, the proportion of shoppers also increased. Prescribers with 66 or more patients receiving opioids, who represented 25 percent of prescribers, prescribed for 82 percent of all shoppers. The great majority of opioid prescribers appear to have no shoppers in their practice. Any educational program will be more cost effective if targeted to prescribers of schedule II opioids with a large volume of patients requiring opioids.

To assess the impact of a closed-loop electronic prescribing, automated dispensing, barcode patient identification and electronic medication administration record (EMAR) system on prescribing and administration errors, confirmation of patient identity before administration, and staff time. Before-and-after study in a surgical ward of a teaching hospital, involving patients and staff of that ward. Closed-loop electronic prescribing, automated dispensing, barcode patient identification and EMAR system. Percentage of new medication orders with a prescribing error, percentage of doses with medication administration errors (MAEs) and percentage given without checking patient identity. Time spent prescribing and providing a ward pharmacy service. Nursing time on medication tasks. Prescribing errors were identified in 3.8% of 2450 medication orders pre-intervention and 2.0% of 2353 orders afterwards (p<0.001; chi(2) test). MAEs occurred in 7.0% of 1473 non-intravenous doses pre-intervention and 4.3% of 1139 afterwards (p = 0.005; chi(2) test). Patient identity was not checked for 82.6% of 1344 doses pre-intervention and 18.9% of 1291 afterwards (p<0.001; chi(2) test). Medical staff required 15 s to prescribe a regular inpatient drug pre-intervention and 39 s afterwards (p = 0.03; t test). Time spent providing a ward pharmacy service increased from 68 min to 98 min each weekday (p = 0.001; t test); 22% of drug charts were unavailable pre-intervention. Time per drug administration round decreased from 50 min to 40 min (p = 0.006; t test); nursing time on medication tasks outside of drug rounds increased from 21.1% to 28.7% (p = 0.006; chi(2) test). A closed-loop electronic prescribing, dispensing and barcode patient identification system reduced prescribing errors and MAEs, and increased confirmation of patient identity before administration. Time spent on medication-related tasks increased.

Clinical nurse specialist prescriber characteristics and challenges in Oregon.

PubMed

Klein, Tracy

2015-01-01

The purpose of this study was to assess role characteristics of clinical nurse specialists (CNSs) with prescriptive authority in Oregon 10 years after passage of Senate Bill 460. Factors examined included role preparation and mentorship, use and maintenance of authority, prescribing benefits and barriers, and types of drugs/nondrugs prescribed. This study was a descriptive survey using both quantitative and qualitative analysis. The sample was obtained from a list provided on June 13, 2014, by the Oregon State Board of Nursing of all CNSs in Oregon who had ever been granted prescriptive authority (n = 40). Twenty-nine with active authority, 7 with expired authority, and 4 with inactive status were sampled. E-mail distribution with Qualtrics software was released on June 27, 2014. Reminder e-mails were sent at 1 and 2 weeks. Of the 38 e-mails successfully delivered, 23 responses were received for a total response rate of 60%. Clinical nurse specialists successfully maintained their authority in Oregon and felt well prepared for their role. Their prescribing mentorship included nurse and nonnurse prescribers. They were most likely to have ever prescribed psychiatric, noncontrolled analgesics and durable medical equipment. They most frequently prescribed nutrition/electrolytes/fluids, durable medical equipment, and controlled analgesics. Lapse in authority was attributed to constraints regarding certification or credentialing in the role. Clinical nurse specialists uniformly expressed benefits from prescriptive authority. There were no differences in perceptions of preparation based on type of mentorship or educational modality for completion of prescribing requirements. There were systems barriers including lack of employer and colleague support to use of authority. Durable medical equipment authority is important to the CNS role. Clinical nurse specialists valued and maintained their prescriptive authority despite barriers. Further research is recommended to support

In 2009, Florida initiated a statewide prescription drug-monitoring program (PDMP) to encourage safer prescribing of controlled substances and reduce drug abuse and diversion. Data supporting the utility of such programs in the emergency department (ED) is scarce. This study sought to determine the effect of PDMP data on controlled substance prescribing from the ED. In this pre-post study utilizing a historical control, pharmacists in the ED provided prescribers with a summary of the PDMP data for their patients. The number of controlled substances prescribed in the intervention group was compared with that prescribed in the historical control to determine if the intervention resulted in a change in the average number of controlled substance prescribed. Among the 710 patients evaluated, providing prescribers with PDMP data did not alter the average number of controlled substance per patient prescribed (0.23 controlled substances per patient in the historical control compared with 0.28 controlled substances per patient in the intervention group; 95% confidence interval [CI], -0.016 to 0.116; P = .125). All prescribers surveyed indicated that having PDMP data altered their controlled substance prescribing and felt more comfortable prescribing controlled substances. Although the results did not demonstrate a change in the average number of controlled substances prescribed when prescribers were provided with PDMP data, results from the survey indicate that prescribers felt the data altered their prescribing of controlled substances, and thus were more contented prescribing controlled substances.

Overprescription of antibiotics is a continuing problem in primary care. This study aims to assess the antibiotic prescribing rates and antibiotic choices for upper respiratory tract infections (URTI) and urinary tract infections (UTI) in Malaysian primary care. Antibiotic prescribing data for URTI and UTI was extracted from a morbidity survey of randomly selected primary care clinics in Malaysia. Analysis was performed of 1,163 URTI and 105 UTI encounters. Antibiotic prescribing rates for URTI and UTI were 33.8% and 57.1% respectively. Antibiotic prescribing rates were higher in private clinics compared to public clinics for URTI, but not for UTI. In URTI encounters, the majority of antibiotics prescribed were penicillins and macrolides, but penicillin V was notably underused. In UTI encounters, the antibiotics prescribed were predominantly penicillins or cotrimoxazole. Greater effort is needed to bring about evidence based antibiotic prescribing in Malaysian primary care, especially for URTIs in private clinics.

Prescriber and institutional barriers and facilitators of clozapine use: A systematic review.

2018-06-04

As clozapine is under-prescribed in persons with treatment-resistant schizophrenia (TRS), it is necessary to better identify the determinants of health inequalities in access to clozapine use. To identify mental health professionals' characteristics or attitudes and institutional characteristics facilitating or limiting clozapine prescribing. We systematically searched multiple electronic databases for articles reporting: (i) mental health professionals' attitudes and characteristics favoring or limiting clozapine prescribing; (ii) institutional characteristics associated with variations in clozapine prescribing; (iii) interventions aimed at enhancing clozapine prescribing. Data were synthesized narratively. A total of 31 articles reporting findings of 29 studies published from 1993 to 2017 in 11 countries fulfilled our inclusion criteria. The main prescriber-related barriers to clozapine prescribing are lack of personal prescribing experience and concern with pharmacological characteristics of clozapine (blood monitoring and adverse effects). Lack of knowledge about the effectiveness of clozapine does not appear as a major determinant of under-prescription. Institutional-related characteristics favoring clozapine prescribing are prescribers' adherence to evidence-based medicine principles and learning by modelling from experienced clozapine prescribers. Effective strategies to increase access to clozapine in persons with TRS include implementation of integrated clozapine clinics, simplification of blood monitoring, education for prescribers and contact with experienced prescribers. Programs addressing barriers in clozapine prescription need to be disseminated more broadly to ensure persons with TRS have access to evidenced based treatments such as clozapine. Inequality in access to clozapine care should be more systematically handled by mental health facilities and health regulatory agencies. Copyright © 2018 Elsevier B.V. All rights reserved.

The pharmacist as prescriber: a discourse analysis of newspaper media in Canada.

Schindel, Theresa J; Given, Lisa M

2013-01-01

Legislation to expand the scope of practice for pharmacists to include authority to independently prescribe medications in Alberta, Canada was announced in 2006 and enacted in April 2007. To date, very little research has explored public views of pharmacist prescribing. This study analyzes newspaper media coverage of pharmacist prescribing 1 year before and 2 years after prescribing was implemented. News items related to pharmacist prescribing were retrieved from 2 national, Canadian newspapers and 5 local newspapers in Alberta over a 3-year period after the announcement of pharmacist prescribing. A purposive sample of 66 texts including news items, editorials, and letters were retrieved electronically from 2 databases, Newscan and Canadian Newsstand. This study uses social positioning theory as a lens for analyzing the discourse of pharmacist prescribing. The results demonstrate a binary positioning of the debate on pharmacist prescribing rights. Using social positioning theory as a lens for analysis, the results illustrate self- and other-positioning of pharmacists' expected roles as prescribers. Themes related to the discourse on pharmacist prescribing include qualifications, diagnosis, patient safety, physician support, and conflict of interest. Media representations of pharmacist prescribing point to polarized views that may serve to shape public, pharmacist, physician, and others' opinions of the issue. Multiple and contradictory views of pharmacist prescribing coexist. Pharmacists and pharmacy organizations are challenged to bring clarity and consistency about pharmacist prescribing to better serve the public interest in understanding options for health care services.

Wilson, Mark

2018-05-01

UK prescribing legislation changes made in 2006 and 2012 enabled appropriately qualified nurses to prescribe any licensed medication, and all controlled drugs in schedule 2-5 of the Misuse of Drugs Regulations 2001, for any medical condition within their clinical competence. Critical Care Outreach nurses who are independent nurse prescribers are ideally placed to ensure that acutely ill patients receive treatment without delay. The perceived challenge was how Critical Care Outreach nurses would be able to safely prescribe for a diverse patient group. This study informs this developing area of nurse prescribing in critical care practice. The aims of the audit were to: identify which medications were prescribed; develop a critical care outreach formulary; identify the frequency, timing and number of prescribing decisions being made; identify if prescribing practice changed over the years and provide information for our continuing professional development. This article reports on data collected from a 5-year retrospective audit; of prescribing activity undertaken by nine independent nurse prescribers working in a 24/7 Critical Care Outreach team of a 600-bedded district general hospital in the UK. In total, 8216 medication items were prescribed, with an average of 2·6 prescribed per shift. The most commonly prescribed items were intravenous fluids and analgesia, which were mostly prescribed at night and weekends. The audit has shown that Critical Care Outreach nurse prescribing is feasible in a whole hospital patient population. The majority of prescribing occurred after 16:00 and at night. Further research would be beneficial, particularly looking at patient outcomes following reviews from prescribing critical care outreach nurses. The audit is one of the only long-term studies that describes prescribing practice in Critical Care Outreach teams in the UK. © 2017 British Association of Critical Care Nurses.

Enantiospecific recognition of DNA sequences by a proflavine Tröger base.

PubMed

Bailly, C; Laine, W; Demeunynck, M; Lhomme, J

2000-07-05

The DNA interaction of a chiral Tröger base derived from proflavine was investigated by DNA melting temperature measurements and complementary biochemical assays. DNase I footprinting experiments demonstrate that the binding of the proflavine-based Tröger base is both enantio- and sequence-specific. The (+)-isomer poorly interacts with DNA in a non-sequence-selective fashion. In sharp contrast, the corresponding (-)-isomer recognizes preferentially certain DNA sequences containing both A. T and G. C base pairs, such as the motifs 5'-GTT. AAC and 5'-ATGA. TCAT. This is the first experimental demonstration that acridine-type Tröger bases can be used for enantiospecific recognition of DNA sequences. Copyright 2000 Academic Press.

1993-01-01

In February 1991, a mail survey was used to poll a sample consisting of about 10 per cent of Ontario's general dentists. The data obtained provided information about the radiographs prescribed by dentists for five different patient types, which were described to the respondents. The per cent agreement between the radiographic procedures prescribed by Ontario dentists and the ADA-approved Center for Devices and Radiological Health (CDRH) guidelines ranged from three per cent to 79 per cent, depending on patient type and disease risk. For each patient and risk type, there was considerable variation in the radiographs prescribed.

Aims The sources of prescribing information are legion but there is little knowledge about which are actually used in practice by doctors when prescribing. The aims of this study were to determine the sources of prescribing information considered important by doctors, establish which were used in practice, and investigate if hospital and primary care physicians differed in their use of the sources. Methods Two hundred general practitioners (GPs) and 230 hospital doctors were asked to rate information sources in terms of their importance for prescribing ‘old’ and ‘new’ drugs, and then to name the source from which information about the last new drug prescribed was actually derived. Results Among 108 GPs, the Drugs and Therapeutics Bulletin and medical journal articles were most frequently rated as important for information on both old and new drugs while pharmaceutical representatives and hospital/consultant recommendations were more important for information on new drugs, as opposed to old. In practice, information on the last new drug prescribed was derived from pharmaceutical representatives in 42% of cases and hospital/consultant recommendations in 36%, with other sources used infrequently. Among 118 hospital doctors, the British National Formulary (BNF) and senior colleagues were of greatest theoretical importance. In practice, information on the last new drug prescribed was derived from a broad range of sources: colleagues, 29%; pharmaceutical representatives, 18%; hospital clinical meetings, 15%; journal articles, 13%; lectures, 10%. GPs and hospital doctors differed significantly in their use of pharmaceutical representatives (42% vs 18%) and colleagues (7% vs 29%) as sources of prescribing information (P < 0.0001 for both). Conclusions The sources most frequently rated important in theory were not those most used in practice, especially among GPs.

A variety of programming techniques and methods of training have been employed to change physician behavior. Didactic continuing medical education lectures and clinical guidelines have had minimal impact, although endorsement of national professional guidelines by local opinion leaders appears to have a positive influence on the impact of professional guidelines. Interactive, hands-on workshops, performance reporting, and peer/patient feedback are also effective. Changing prescribing habits has been equally difficult. Drug utilization letters involving both pharmacist and physician have more impact than do letters sent only to the physician. Academic detailing, when properly executed, has been consistently effective. When combined with these strategies, closed formularies become a powerful tool in changing prescribing behavior.

During ancient times, fire was an important factor shaping European landscapes. Nowadays, prescribed burning can be one of the most effective conservation tools for the management of open landscapes, controlling dominant species, reducing accumulated litter or decreasing wildfire risk. In a prescribed burning experiment, we studied the effects of fire on dry alkaline grasslands. We tested whether autumn prescribed burning can be an alternative conservation measure in these grasslands. We selected six sites in Hungary: in three sites, prescribed burning was applied in November 2011, while three sites remained unburnt. We studied the effects of fire on soil characteristics, plant biomass and on the vegetation and arthropod assemblages (isopods, spiders, ground beetles and rove beetles). Soluble salt content increased significantly in the burnt sites, but soil pH, organic matter, potassium and phosphorous did not change. We found that prescribed fire had several positive effects from the nature conservation viewpoint. Diversity and the number of flowering shoots were higher, and the cover of the dominant grass was lower in the burnt sites. Graminoid biomass was lower, while total, green and forb biomass were higher in the burnt plots compared to the control ones. Our findings suggest that prescribed burning fire did not harm arthropods; species-level analyses showed that out of the most abundant invertebrate species, the abundance of ten was not affected, one decreased and one increased after burning. Our findings highlight that mosaic prescribed fire is a viable management tool in open landscapes, because it supports plant diversity and does not threaten arthropods.

Here we present the results for four 'hot-Jupiter systems' with near-solar stars-HAT-P-4, TrES-3, TrES-2, and WASP-3. We observe 10 transits of HAT-P-4, estimating the planet radius R{sub p} = 1.332 {+-} 0.052 R{sub Jup}, the stellar radius R{sub *} = 1.602 {+-} 0.061 R{sub sun}, the inclination i = 89.67 {+-} 0.30 deg, and the transit duration from first to fourth contact {tau} = 255.6 {+-} 1.9 minutes. Formore » TrES-3, we observe seven transits and find R{sub p} = 1.320 {+-} 0.057 R{sub Jup}, R{sub *} = 0.817 {+-} 0.022 R{sub sun}, i = 81.99 {+-} 0.30 deg, and {tau} = 81.9 {+-} 1.1 minutes. We also note a long-term variability in the TrES-3 light curve, which may be due to star spots. We observe nine transits of TrES-2 and find R{sub p} = 1.169 {+-} 0.034 R{sub Jup}, R{sub *} = 0.940 {+-} 0.026 R{sub sun}, i = 84.15 {+-} 0.16 deg, and {tau} = 107.3 {+-} 1.1 minutes. Finally, we observe eight transits of WASP-3, finding R{sub p} = 1.385 {+-} 0.060 R{sub Jup}, R{sub *} = 1.354 {+-} 0.056 R{sub sun}, i = 84.22 {+-} 0.81 deg, and {tau} = 167.3 {+-} 1.3 minutes. We present refined orbital periods and times of transit for each target. We state 95% confidence upper limits on the secondary eclipse depths in our broadband visible bandpass centered on 650 nm. These limits are 0.073% for HAT-P-4, 0.062% for TrES-3, 0.16% for TrES-2, and 0.11% for WASP-3.

To provide information on the profile and practice of nurses in the UK who prescribe medication for pain. Pain is widely under-reported and under-treated and can have negative consequences for health and psychosocial well-being. Indications are that nurses can improve treatment and access to pain medications when they prescribe. Whilst nurses working in many practice areas treat patients with pain, little is known about the profile, prescribing practice or training needs of these nurses. A descriptive questionnaire survey. An online questionnaire was used to survey 214 nurses who prescribed for pain in the UK between May and July 2010. Data were analysed using descriptive statistics and non-parametric tests. Half the participants (50%) worked in primary care, 32% in secondary care and 14% worked across care settings. A range of services were provided, including general practice, palliative care, pain management, emergency care, walk-in-centres and out-of-hours. The majority (86%) independently prescribed 1-20 items per week. Non-opioid and weak opioids analgesics were prescribed by most (95%) nurses, whereas fewer (35%) prescribed strong opioids. Training in pain had been undertaken by 97% and 82% felt adequately trained, although 28% had problems accessing training. Those with specialist training prescribed a wider range of pain medications, were more likely to prescribe strong opioids and were more often in pain management roles. Nurses prescribe for pain in a range of settings with an emphasis on the treatment of minor ailments and acute pain. A range of medications are prescribed, and most nurses have access to training. The nursing contribution to pain treatment must be acknowledged within initiatives to improve pain management. Access to ongoing training is required to support nurse development in this area of practice to maximise benefits. © 2012 Blackwell Publishing Ltd.

Prescribing is an essential element of health visiting practice. This initiative used the payment framework of Commissioning for Quality and Innovation (CQUIN) to develop health visiting practice across a large health visiting workforce in the East Midlands. A focus on emollient prescribing practice was agreed and a guidance booklet regarding preferred emollient products was produced, based on the local formulary Each health visitor benefitted from receiving additional training and was given a guidance booklet to inform their practice. Targets were set for each quarter to demonstrate an improved prescribing adherence to the preferred product list.The targets were achieved for each quarter. Prescribing rates and confidence improved across the service. Therefore, it was demonstrated that specific guidance and ongoing support can improve prescribing practice within the health visiting service.

Transactivation of the proximal promoter of human oxytocin gene by TR4 orphan receptor

The human testicular receptor 4 (TR4) shares structural homology with members of the nuclear receptor superfamily. Some other members of this superfamily were able to regulate the transcriptional activity of the human oxytocin (OXT) promoter by binding to the first DR0 regulatory site. However, little investigation was conducted systematically in the study of the second dDR4 site of OXT proximal promoter, and the relationship between the first and the second sites of OXT promoter. Here, we demonstrated for the first time that TR4 could increase the proximal promoter activity of the human OXT gene via DR0, dDR4, and OXT (bothmore » DR0 and dDR4) elements, respectively. TR4 might induce OXT gene expression through the OXT element in a dose-dependent manner. However, there is no synergistic effect between DR0 and dDR4 elements during TR4 transactivation. Taken together, these results suggested that TR4 should be one of important regulators of OXT gene expression.« less

Electronic prescribing (e-prescribing) with formulary decision support (FDS) prompts prescribers to prescribe lower-cost medications and may help contain health care costs. In April 2004, 2 large Massachusetts insurers began providing an e-prescribing system with FDS to community-based practices. Using 18 months (October 1, 2003, to March 31, 2005) of administrative data, we conducted a pre-post study with concurrent controls. We first compared the change in the proportion of prescriptions for 3 formulary tiers before and after e-prescribing began, then developed multivariate longitudinal models to estimate the specific effect of e-prescribing when controlling for baseline differences between intervention and control prescribers. Potential savings were estimated using average medication costs by formulary tier. More than 1.5 million patients filled 17.4 million prescriptions during the study period. Multivariate models controlling for baseline differences between prescribers and for changes over time estimated that e-prescribing corresponded to a 3.3% increase (95% confidence interval, 2.7%-4.0%) in tier 1 prescribing. The proportion of prescriptions for tiers 2 and 3 (brand-name medications) decreased correspondingly. e-Prescriptions accounted for 20% of filled prescriptions in the intervention group. Based on average costs for private insurers, we estimated that e-prescribing with FDS at this rate could result in savings of $845,000 per 100,000 patients. Higher levels of e-prescribing use would increase these savings. Clinicians using e-prescribing with FDS were significantly more likely to prescribe tier 1 medications, and the potential financial savings were substantial. Widespread use of e-prescribing systems with FDS could result in reduced spending on medications.

The use and overuse of antibiotics in humans is a major contributor to the selection of antibiotic resistance organisms. Recent evidence has shown that primary care prescribing selects for resistances of clinical importance. The National Prescribing Service runs both educational and audit activities. The latter provide some insight into general practice attitudes toward antibiotic prescribing.

To investigate the antibiotic prescribing training received by dental students, clinical experience in treating child patients, awareness of antibiotic prescribing guidelines, preparedness in antibiotic prescribing, and compliance with antibiotic prescribing guidelines for the management of dental infections in children. This was a cross-sectional study involving final year dentals students from Malaysian and Asian dental schools. A self-administered questionnaire consisting of five clinical case scenarios was e-mailed to all final year students at selected dental schools. Students' responses were compared for each clinical case scenario with the prescribing guidelines of the American Academy of Pediatric Dentistry and the American Dental Association. Compliance in each scenario was tested for association with their preparedness in antibiotic prescribing, previous training on antibiotic prescribing and awareness of antibiotic prescribing guidelines using Chi-square test. Data collected were analyzed using SPSS statistics version 20. A total of 108 completed responses were received. About 74 (69%) students were from Malaysian dental schools. The compliance rate with prescribing guidelines ranged from 15.7% to 43.5%. Those attending Malaysian dental schools (47.3%) and those who had treated child patient more often (46.3%) were more likely (P < 0.05) to be aware of the guidelines. Those who had received antibiotic prescribing training (21.3%) were more likely to think they were well prepared in antibiotic prescribing (P < 0.05). Final year dental students had low awareness and compliance with antibiotic prescribing guidelines. Further research is needed to investigate how compliance with the guidelines may be enhanced.

2018-06-01

The classical nova NR TrA was discovered as an O-type optically-thick classical nova. There is no evidence that it formed dust. Within four years the envelope became sufficiently thin to reveal an eclipsing accretion disk-dominated system with orbitally-modulated permitted lines of C IV, N V, and O VI. XMM observations reveal a non-eclipsing soft X-ray source and a deeply-eclipsing UV continuum. We will present the first ten years of optical spectral evolution of this system accompanied by ten years of BVRIJHK photometry, with an eye to deciphering the current nature of the system.

The impact of nurse prescribing on the clinical setting.

PubMed

Creedon, Rena; Byrne, Stephen; Kennedy, Julia; McCarthy, Suzanne

To investigate the impact nurse prescribing has on the organisation, patient and health professional, and to identify factors associated with the growth of nurse prescribing. Systematic search and narrative review. Data obtained through CINAHL, PubMed, Science direct, Online Computer Library Centre (OCLC), databases/websites, and hand searching. English peer-reviewed quantitative, qualitative and mixed-method articles published from September 2009 through to August 2014 exploring nurse prescribing from the perspective of the organisation, health professional and patient were included. Following a systematic selection process, studies identified were also assessed for quality by applying Cardwell's framework. From the initial 443 citations 37 studies were included in the review. Most studies were descriptive in nature. Commonalities addressed were stakeholders' views, prescribing in practice, jurisdiction, education and benefits/barriers. Prescriptive authority for nurses continues to be a positive addition to clinical practice. However, concerns have emerged regarding appropriate support, relationships and jurisdictional issues. A more comprehensive understanding of nurse and midwife prescribing workloads is required to capture the true impact and cost-effectiveness of the initiative.

Physicians prescribing new medications often do not convey important medication-related information. This study tests an intervention to improve physician-patient communication about newly prescribed medications. We conducted a controlled clinical trial of patients in 3 primary care practices, combining data from patient surveys with audio-recorded physician-patient interactions. The intervention consisted of a 1-hour physician-targeted interactive educational session encouraging communication about 5 basic elements regarding a new prescription and a patient information handout listing the 5 basic elements. Main outcome measures were the Medication Communication Index (MCI), a 5-point index assessed by qualitative analysis of audio-recorded interactions (giving points for discussion of medication name, purpose, directions for use, duration of use, and side effects), and patient ratings of physician communication about new prescriptions. Twenty-seven physicians prescribed 113 new medications to 82 of 256 patients. The mean MCI for medications prescribed by physicians in the intervention group was 3.95 (SD = 1.02), significantly higher than that for medications prescribed by control group physicians (2.86, SD = 1.23, P <.001). This effect held regardless of medication type (chronic vs nonchronic medication). Counseling about 3 of the 5 MCI components was significantly higher for medications prescribed by physicians in the intervention group, as were patients' ratings of new medication information transfer (P = .02). Independent of intervention or control groups, higher MCI scores were associated with better patient ratings about information about new prescriptions (P = .003). A physician-targeted educational session improved the content of and enhanced patient ratings of physician communication about new medication prescriptions. Further work is required to assess whether improved communication stimulated by the intervention translates into better clinical outcomes.

Objectives To assess the impact of a closed‐loop electronic prescribing, automated dispensing, barcode patient identification and electronic medication administration record (EMAR) system on prescribing and administration errors, confirmation of patient identity before administration, and staff time. Design, setting and participants Before‐and‐after study in a surgical ward of a teaching hospital, involving patients and staff of that ward. Intervention Closed‐loop electronic prescribing, automated dispensing, barcode patient identification and EMAR system. Main outcome measures Percentage of new medication orders with a prescribing error, percentage of doses with medication administration errors (MAEs) and percentage given without checking patient identity. Time spent prescribing and providing a ward pharmacy service. Nursing time on medication tasks. Results Prescribing errors were identified in 3.8% of 2450 medication orders pre‐intervention and 2.0% of 2353 orders afterwards (p<0.001; χ2 test). MAEs occurred in 7.0% of 1473 non‐intravenous doses pre‐intervention and 4.3% of 1139 afterwards (p = 0.005; χ2 test). Patient identity was not checked for 82.6% of 1344 doses pre‐intervention and 18.9% of 1291 afterwards (p<0.001; χ2 test). Medical staff required 15 s to prescribe a regular inpatient drug pre‐intervention and 39 s afterwards (p = 0.03; t test). Time spent providing a ward pharmacy service increased from 68 min to 98 min each weekday (p = 0.001; t test); 22% of drug charts were unavailable pre‐intervention. Time per drug administration round decreased from 50 min to 40 min (p = 0.006; t test); nursing time on medication tasks outside of drug rounds increased from 21.1% to 28.7% (p = 0.006; χ2 test). Conclusions A closed‐loop electronic prescribing, dispensing and barcode patient identification system reduced prescribing errors and MAEs, and increased confirmation of patient identity before

2008-10-01

To reduce prescribing errors in an intensive care unit by providing prescriber education in tutorials, ward-based teaching and feedback in 3-monthly cycles with each new group of trainee medical staff. Prescribing audits were conducted three times in each 3-month cycle, once pretraining, once post-training and a final audit after 6 weeks. The audit information was fed back to prescribers with their correct prescribing rates, rates for individual error types and total error rates together with anonymised information about other prescribers' error rates. The percentage of prescriptions with errors decreased over each 3-month cycle (pretraining 25%, 19%, (one missing data point), post-training 23%, 6%, 11%, final audit 7%, 3%, 5% (p<0.0005)). The total number of prescriptions and error rates varied widely between trainees (data collection one; cycle two: range of prescriptions written: 1-61, median 18; error rate: 0-100%; median: 15%). Prescriber education and feedback reduce manual prescribing errors in intensive care.

How well are general practice trainees prepared for paediatric prescribing?

Isa, N M; Taylor, Michael W; Helms, Peter J; McLay, James S

2009-03-01

We invited 232 General Practice Trainees to complete an on-line questionnaire to assess how they rated their training for the task of paediatric prescribing and therapeutics in the community. Of the 166 (71%) respondents who completed the questionnaire, 26.5% recalled specific teaching about paediatric prescribing and 59.6% covering one or more relevant topic during their undergraduate years. Undertaking a paediatric post during vocational training was associated with greater prescribing confidence (P < 0.001); however, 35% of respondents were not intending to undertake such a post. This study suggests that many GP trainees perceive their paediatric prescribing training as inadequate.

Non-prescribed use of pain relievers among adolescents in the United States.

2008-04-01

We examined gender-specific prevalences, patterns, and correlates of non-prescribed use of pain relievers - mainly opioids - in a representative sample of American adolescents (N=18,678). Data were drawn from the public use data file of the 2005 U.S. National Survey on Drug Use and Health, a survey of non-institutionalized American household residents. The patterns of non-prescribed use of prescription pain relievers were examined, and logistic regression procedures were conducted to identify correlates of non-prescribed use. Approximately one in 10 adolescents aged 12-17 years reported non-prescribed use of pain relievers in their lifetime (9.3% in males and 10.3% in females). The mean age of first non-prescribed use was 13.3 years, which was similar to the mean age of first use of alcohol and marijuana but older than the age of first inhalant use. Among all non-prescribed users, 52% reported having used hydrocodone products (Vicodin, Lortab, Lorcet, and Lorcet Plus, and hydrocodone), 50% had used propoxyphene (Darvocet or Darvon) or codeine (Tylenol with codeine), and 24% had used oxycodone products (OxyContin, Percocet, Percodan, and Tylox). Approximately one quarter (26%) of all non-prescribed users had never used other non-prescribed or illicit drugs. There were gender variations in correlates of non-prescribed use. Use of non-prescribed pain relievers occurs early in adolescence. Research is needed to understand whether early use of non-prescribed pain relievers is related to later drug use.

E-Prescribing Errors in Community Pharmacies: Exploring Consequences and Contributing Factors

Stone, Jamie A.; Chui, Michelle A.

2014-01-01

Objective To explore types of e-prescribing errors in community pharmacies and their potential consequences, as well as the factors that contribute to e-prescribing errors. Methods Data collection involved performing 45 total hours of direct observations in five pharmacies. Follow-up interviews were conducted with 20 study participants. Transcripts from observations and interviews were subjected to content analysis using NVivo 10. Results Pharmacy staff detected 75 e-prescription errors during the 45 hour observation in pharmacies. The most common e-prescribing errors were wrong drug quantity, wrong dosing directions, wrong duration of therapy, and wrong dosage formulation. Participants estimated that 5 in 100 e-prescriptions have errors. Drug classes that were implicated in e-prescribing errors were antiinfectives, inhalers, ophthalmic, and topical agents. The potential consequences of e-prescribing errors included increased likelihood of the patient receiving incorrect drug therapy, poor disease management for patients, additional work for pharmacy personnel, increased cost for pharmacies and patients, and frustrations for patients and pharmacy staff. Factors that contribute to errors included: technology incompatibility between pharmacy and clinic systems, technology design issues such as use of auto-populate features and dropdown menus, and inadvertently entering incorrect information. Conclusion Study findings suggest that a wide range of e-prescribing errors are encountered in community pharmacies. Pharmacists and technicians perceive that causes of e-prescribing errors are multidisciplinary and multifactorial, that is to say e-prescribing errors can originate from technology used in prescriber offices and pharmacies.

Wee1, the Cdc2 inhibitory kinase, needs to be down-regulated at the onset of mitosis to ensure rapid activation of Cdc2. Previously, we have shown that human somatic Wee1 (Wee1A) is down-regulated both by protein phosphorylation and degradation, but the underlying mechanisms had not been elucidated. In the present study, we have identified the β-transducin repeat-containing protein 1/2 (β-TrCP1/2) F-box protein-containing SKP1/Cul1/F-box protein (SCF) complex (SCFβ-TrCP1/2) as an E3 ubiquitin ligase for Wee1A ubiquitination. Although Wee1A lacks a consensus DS(p)GXXS(p) phospho-dependent binding motif for β-TrCP, recognition of Wee1A by β-TrCP depended on phosphorylation, and two serine residues in Wee1A, S53 and S123, were found to be the most important phosphorylation sites for β-TrCP recognition. We have found also that the major M-phase kinases polo-like kinase 1 (Plk1) and Cdc2 are responsible for the phosphorylation of S53 and S123, respectively, and that in each case phosphorylation generates an unconventional phospho-degron (signal for degradation) that can be recognized by β-TrCP. Phosphorylation of Wee1A by these kinases cooperatively stimulated the recognition and ubiquitination of Wee1A by SCFβ-TrCP1/2 in vitro. Mutation of these residues or depletion of β-TrCP by small-interfering RNA treatment increased the stability of Wee1A in HeLa cells. Moreover, our analysis indicates that β-TrCP-dependent degradation of Wee1A is important for the normal onset of M-phase in vivo. These results also establish the existence of a feedback loop between Cdc2 and Wee1A in somatic cells that depends on ubiquitination and protein degradation and ensures the rapid activation of Cdc2 when cells are ready to divide.

2009-03-01

To update 2 comprehensive reviews of systematic reviews on prescribing interventions and identify the latest evidence about the effectiveness of the interventions. Systematic searches for English-language reports of experimental and quasi-experimental research were conducted in PubMed (1951-May 2007), EMBASE (1974-March 2008), International Pharmaceutical Abstracts (1970-March 2008), and 11 other bibliographic databases of medical, social science, and business research. Following an initial title screening process and after selecting 6 specific intervention categories (identified from the previous reviews) in community settings, 2 reviewers independently assessed abstracts and then full studies for relevance and quality and extracted relevant data using formal assessment and data extraction tools. Results were then methodically incorporated into the findings of the 2 earlier reviews of systematic reviews. DATA SELECTION AND SYNTHESIS: Twenty-nine of 26,314 articles reviewed were assessed to be of relevant, high-quality research. Audit and feedback, together with educational outreach visits, were the focus of the majority of recent, high-quality research into prescribing interventions. These interventions were also the most effective in improving prescribing practice. A smaller number of studies included a patient-mediated intervention; this intervention was not consistently effective. There is insufficient recent research into manual reminders to confidently update earlier reviews and there remains insufficient evidence to draw conclusions regarding the effectiveness of local consensus processes or multidisciplinary teams. Educational outreach as well as audit and feedback continue to dominate research into prescribing interventions. These 2 prescribing interventions also most consistently show positive results. Much less research is conducted into other types of interventions and there is still very little effort to systematically test why interventions do or do

The United States is in the midst of an opioid epidemic. These medications continue to be used to manage pain associated with osteoarthritis, despite mounting evidence questioning the benefits. The rate at which opioids are prescribed for osteoarthritis is largely unknown. We sought to identify rates of opioid prescriptions for osteoarthritis and identify factors associated with higher rates of prescribing. We queried the Humana, Inc. administrative claims database from 2007 to 2014. Patients with osteoarthritis were identified using International Classification of Diseases 9th Revision codes and classified as having hip, knee, or any joint osteoarthritis. Claims data were reviewed to identify opioid prescriptions associated with a diagnosis of osteoarthritis. Rates of prescribing were trended over time and stratified by sex, age, and geographic region. From 2007 to 2014, 17.0% of patients with any joint osteoarthritis, 13.4% of patients with hip osteoarthritis, and 15.9% with knee osteoarthritis were prescribed an opioid for their condition. Yearly rates of prescription were fairly stable over this period. Patients in the South had the highest odds of opioid prescription, while those in the Northeast had the lowest. Patients ≤49 years old were more likely to receive a prescription than those ≥50 years old. This study provides important epidemiologic data about the use of opioids for osteoarthritis. Despite increasing evidence calling proposed benefits into question and increasing awareness of risks of opioids, prescribing rates remained stable between 2007 and 2014. This provides important baseline data as we work to combat excessive and inappropriate opioid use within the United States. Copyright © 2017 Elsevier Inc. All rights reserved.

To audit oxygen prescribing in a children's hospital following the introduction of a new paediatric medication chart, which incorporates an oxygen prescription section. In June 2015 a 1-day snapshot audit was carried out across all wards in the children's hospital. All patients receiving oxygen on that day were included:▸ The audit was repeated in July 2015.▸ The standards for the audit were set at 100% in accordance with our local guidelines.1 ▸ All patients receiving oxygen should have a prescription. Of these:▸ All patients should have target saturations identified.▸ All patients should have an administration device identified.▸ All patients should have a nurse signature on the chart within the last 12 hrs. In June, 13 patients were receiving oxygen on the audit day. 0/14 had a prescription.In July, 18 patients were receiving oxygen on the audit day. (14 critical care, 4 medicine).4/18 had an oxygen prescription (22%). These were all medical patients. Of these, 4 patients had a target saturation identified (100%), 1 had a device prescribed (25%), and 4 had a nurse signature within the last 12 hrs (100%). The initial audit showed no compliance with either local or national guidance for oxygen prescribing.1 2 The re-audit showed improved prescribing on the medical wards but not within critical care. The new paediatric medication chart was launched early in 2015, along with a training package for doctors, nurses and pharmacists. This was in response to the National Patient Safety Agency (NPSA) rapid response report on oxygen safety in hospitals.3 There was a gap between the training and the new charts being available which may have led to the poor results in the first audit. Increased awareness of the charts and the initial audit results probably helped improve prescribing in the re-audit. For medical patients, prescribing and monitoring was good, although device was infrequently prescribed. Critical care have not engaged with the new chart

We report on observations of several transit events of the transiting planet TrES-2 obtained with the Cassegrain-Teleskop-Kamera at the University Observatory Jena. Between March 2007 and November 2008 ten different transits and almost a complete orbital period were observed. Overall, in 40 nights of observation 4291 exposures (in total 71.52 h of observation) of the TrES-2 parent star were taken. With the transit timings for TrES-2 from the 34 events published by the TrES-network, the Transit Light Curve project and the Exoplanet Transit Database plus our own ten transits, we find that the orbital period is P=(2.470614± 0.000001) d, a slight change by ˜ 0.6 s compared to the previously published period. We present new ephemeris for this transiting planet. Furthermore, we found a second dip after the transit which could either be due to a blended variable star or occultation of a second star or even an additional object in the system. Our observations will be useful for future investigations of timing variations caused by additional perturbing planets and/or stellar spots and/or moons. Based on observations obtained with telescopes of the University Observatory Jena, which is operated by the Astrophysical Institute of the Friedrich-Schiller-University Jena and the 80cm telescope of the Wendelstein Observatory of the Ludwig-Maximilians-University Munich.

While approximately half of all qualified hospital pharmacist independent prescribers (PIPs) in Scotland are active prescribers, there are major differences in prescribing activity across geographical areas. This study aimed to explore, through focus groups, interviews and a questionnaire, hospital PIPs' perceptions of factors associated with prescribing activity and to investigate the infrastructure required to better support active prescribing by PIPs. Findings reinforced the perceived positive impact of supportive pharmacy leadership within the organisation, recognition that prescribing is integral to the clinical pharmacist role and a work environment conducive to prescribing.

Stern, R S

1996-08-01

Topical corticosteroids are widely used in the treatment of skin diseases. These preparations vary greatly in potency. They are available in both brand name and generic formulations, as well as in combination products. Our purpose was to determine the pattern of topical corticosteroids prescribing in the United States and the relation of patient and prescriber attributes to the type of corticosteroid preparation prescribed. Data from the 1989 to 1991 National Ambulatory Medical Care Survey were used to estimate the number of visits with a topical corticosteroid preparation prescribed and to identify prescribers with specific characteristics. In the United States, topical corticosteroids are prescribed or recommended at an average of 14 million visits per year to office-based health practitioners. Forty percent of these visits were to dermatologists. Dermatologists were 3.9 times more likely to prescribe very high potency steroids than were other physicians. Physicians other than dermatologists were 8.4 times more likely than dermatologists to prescribe combination agents containing moderate- or high-potency topical corticosteroids and an antiinfective agent. The pattern of topical corticosteroid prescribing is substantially different for dermatologists and other physicians. These differences may reflect differences in severity or complexity of the disease or differences in prescribing habits. The importance of these differences to the outcome of treated patients is not established.

Carberry, Martin; Connelly, Sarah; Murphy, Jennifer

2013-05-01

To determine the prescribing activity of different staff groups within intensive care unit (ICU) and combined high dependency unit (HDU), namely trainee and consultant medical staff and advanced nurse practitioners in critical care (ANPCC); to determine the number and type of prescription errors; to compare error rates between prescribing groups and to raise awareness of prescribing activity within critical care. The introduction of government legislation has led to the development of non-medical prescribing roles in acute care. This has facilitated an opportunity for the ANPCC working in critical care to develop a prescribing role. The audit was performed over 7 days (Monday-Sunday), on rolling days over a 7-week period in September and October 2011 in three ICUs. All drug entries made on the ICU prescription by the three groups, trainee medical staff, ANPCCs and consultant anaesthetists, were audited once for errors. Data were collected by reviewing all drug entries for errors namely, patient data, drug dose, concentration, rate and frequency, legibility and prescriber signature. A paper data collection tool was used initially; data was later entered onto a Microsoft Access data base. A total of 1418 drug entries were audited from 77 patient prescription Cardexes. Error rates were reported as, 40 errors in 1418 prescriptions (2·8%): ANPCC errors, n = 2 in 388 prescriptions (0·6%); trainee medical staff errors, n = 33 in 984 (3·4%); consultant errors, n = 5 in 73 (6·8%). The error rates were significantly different for different prescribing groups (p < 0·01). This audit shows that prescribing error rates were low (2·8%). Having the lowest error rate, the nurse practitioners are at least as effective as other prescribing groups within this audit, in terms of errors only, in prescribing diligence. National data is required in order to benchmark independent nurse prescribing practice in critical care. These findings could be used to inform research and role

Nurses are able to prescribe independently from a list of nearly 250 prescription only medicines for a range of over 100 medical conditions or, from the whole British National Formulary as a supplementary prescriber. There is some evidence available on the prescribing practices of district nurses and health visitors and early independent extended prescribers. Little or no attention has focussed on supplementary nurse prescribing. To provide an overview of the prescribing practices of independent extended/supplementary nurse prescribers and the factors that facilitate or inhibit prescribing. National questionnaire survey. United Kingdom. A convenience sample of 868 qualified independent extended/supplementary nurse prescribers self-completed a written questionnaire. A total of 756 (87%) used independent extended prescribing; 304 (35%) used supplementary prescribing to treat a range of chronic conditions (including asthma, diabetes and hypertension); 710 (82%) nurses worked in primary care. Nurses in general practice reported the largest number of reasons preventing prescribing. Reasons included the inability to computer generate prescriptions and to implement the Clinical Management Plan. Nurses in primary care reported more continuing professional development needs. These needs included update on prescribing policy and the treatment management of conditions. A total of 277 (32%) nurses were unable to access continuing professional development. Independent extended/supplementary nurse prescribers work predominantly in primary care and do prescribe medicines. These nurses are highly qualified and have many years clinical experience. Supplementary prescribing is used by a minority of nurses. Implementing the Clinical Management Plan is a barrier preventing the use of this mode of prescribing. The continuing professional development needs of independent extended/supplementary nurse prescribers are frequently unmet. It will become increasingly important that these needs

Background We examined gender-specific prevalences, patterns, and correlates of non-prescribed use of pain relievers—mainly opioids—in a representative sample of American adolescents (N = 18,678). Methods Data were drawn from the public use data file of the 2005 U.S. National Survey on Drug Use and Health, a survey of non-institutionalized American household residents. The patterns of non-prescribed use of prescription pain relievers were examined, and logistic regression procedures were conducted to identify correlates of non-prescribed use. Results Approximately one in 10 adolescents aged 12−17 years reported non-prescribed use of pain relievers in their lifetime (9.3% in males and 10.3% in females). The mean age of first non-prescribed use was 13.3 years, which was similar to the mean age of first use of alcohol and marijuana but older than the age of first inhalant use. Among all non-prescribed users, 52% reported having used hydrocodone products (Vicodin, Lortab, Lorcet, and Lorcet Plus, and hydrocodone), 50% had used propoxyphene (Darvocet or Darvon) or codeine (Tylenol with codeine), and 24% had used oxycodone products (OxyContin, Percocet, Percodan, and Tylox). Approximately one quarter (26%) of all non-prescribed users had never used other non-prescribed or illicit drugs. There were gender variations in correlates of non-prescribed use. Conclusions Use of non-prescribed pain relievers occurs early in adolescence. Research is needed to understand whether early use of non-prescribed pain relievers is related to later drug use.

Electronic prescribing in ambulatory practice: promises, pitfalls, and potential solutions.

PubMed

Papshev, D; Peterson, A M

2001-07-01

To examine advantages of and obstacles to electronic prescribing in the ambulatory care environment. MEDLINE and International Pharmaceutical Abstract searches were conducted for the period from January 1980 to September 2000. Key words were electronic prescribing, computerized physician order entry, prior authorization, drug utilization review, and consumer satisfaction. In September 2000, a public search engine (www.google.com) was used to find additional technical information. In addition, pertinent articles were cross-referenced to identify other resources. Articles, symposia proceedings, and organizational position statements published in the United States on electronic prescribing and automation in healthcare are cited. Electronic prescribing can eliminate the time gap between point of care and point of service, reduce medication errors, improve quality of care, and increase patient satisfaction. Considerable funding requirements, segmentation of healthcare markets, lack of technology standardization, providers' resistance to change, and regulatory indecisiveness create boundaries to the widespread use of automated prescribing. The potential solutions include establishing a standardizing warehouse or a router and gaining stakeholder support in implementation of the technology. Electronic prescribing can provide immense benefits to healthcare providers, patients, and managed care. Resolution of several obstacles that limit feasibility of this technology will determine its future.

Rationalising prescribing: Evidence, marketing and practice-relevant knowledge.

PubMed

Wadmann, Sarah; Bang, Lia E

2015-06-01

Initiatives in the name of 'rational pharmacotherapy' have been launched to alter what is seen as 'inappropriate' prescribing practices of physicians. Based on observations and interviews with 20 general practitioners (GPs) in 2009-2011, we explored how attempts to rationalise prescribing interact with chronic care management in Denmark. We demonstrate how attempts to rationalise prescribing by informing GPs about drug effects, adverse effects and price do not satisfy GPs' knowledge needs. We argue that, for GPs, 'rational' prescribing cannot be understood in separation from the processes that enable patients to use medication. Therefore, GPs do much more to obtain knowledge about medications than seek advice on 'rational pharmacotherapy'. For instance, GPs also seek opportunities to acquaint themselves with the material objects of medication and medical devices. We conceptualise the knowledge needs of GPs as a need for practice-relevant knowledge and argue that industry sales representatives are granted opportunity to access general practice because they understand this need of GPs.

To explore types of e-prescribing errors in community pharmacies and their potential consequences, as well as the factors that contribute to e-prescribing errors. Data collection involved performing 45 total hours of direct observations in five pharmacies. Follow-up interviews were conducted with 20 study participants. Transcripts from observations and interviews were subjected to content analysis using NVivo 10. Pharmacy staff detected 75 e-prescription errors during the 45 h observation in pharmacies. The most common e-prescribing errors were wrong drug quantity, wrong dosing directions, wrong duration of therapy, and wrong dosage formulation. Participants estimated that 5 in 100 e-prescriptions have errors. Drug classes that were implicated in e-prescribing errors were antiinfectives, inhalers, ophthalmic, and topical agents. The potential consequences of e-prescribing errors included increased likelihood of the patient receiving incorrect drug therapy, poor disease management for patients, additional work for pharmacy personnel, increased cost for pharmacies and patients, and frustrations for patients and pharmacy staff. Factors that contribute to errors included: technology incompatibility between pharmacy and clinic systems, technology design issues such as use of auto-populate features and dropdown menus, and inadvertently entering incorrect information. Study findings suggest that a wide range of e-prescribing errors is encountered in community pharmacies. Pharmacists and technicians perceive that causes of e-prescribing errors are multidisciplinary and multifactorial, that is to say e-prescribing errors can originate from technology used in prescriber offices and pharmacies.

[Prescribing antibiotics for sore throat: a persistent habit].

PubMed

Damoiseaux, Roger A M J; Venekamp, Roderick P

2015-01-01

Recently the revision of the guideline of the Dutch College of General Practitioners on sore throat has been published. Again, one of the key messages is restricting the use of antibiotics. In the Netherlands general practitioners prescribe antibiotics in 50% of cases of tonsillitis. Although there has been a decrease in the number of antibiotic prescriptions for tonsillitis in the last 30 years, they are still being prescribed twice as often as is recommended by the guideline. The beliefs of both patient and doctor play an important role in prescribing and better communication might help to improve the situation. Public campaigns can also help by providing the best knowledge on the effectiveness of antibiotics to the public.

2011-01-01

Objective Expert authorities recommend clinical decision support systems to reduce prescribing error rates, yet large numbers of insignificant on-screen alerts presented in modal dialog boxes persistently interrupt clinicians, limiting the effectiveness of these systems. This study compared the impact of modal and non-modal electronic (e-) prescribing alerts on prescribing error rates, to help inform the design of clinical decision support systems. Design A randomized study of 24 junior doctors each performing 30 simulated prescribing tasks in random order with a prototype e-prescribing system. Using a within-participant design, doctors were randomized to be shown one of three types of e-prescribing alert (modal, non-modal, no alert) during each prescribing task. Measurements The main outcome measure was prescribing error rate. Structured interviews were performed to elicit participants' preferences for the prescribing alerts and their views on clinical decision support systems. Results Participants exposed to modal alerts were 11.6 times less likely to make a prescribing error than those not shown an alert (OR 11.56, 95% CI 6.00 to 22.26). Those shown a non-modal alert were 3.2 times less likely to make a prescribing error (OR 3.18, 95% CI 1.91 to 5.30) than those not shown an alert. The error rate with non-modal alerts was 3.6 times higher than with modal alerts (95% CI 1.88 to 7.04). Conclusions Both kinds of e-prescribing alerts significantly reduced prescribing error rates, but modal alerts were over three times more effective than non-modal alerts. This study provides new evidence about the relative effects of modal and non-modal alerts on prescribing outcomes. PMID:21836158

Building a standards-based and collaborative e-prescribing tool: MyRxPad.

PubMed

2011-01-01

MyRxPad (rxp.nlm.nih.gov) is a prototype application intended to enable a practitioner-patient collaborative approach towards e-prescribing: patients play an active role by maintaining up-to-date and accurate medication lists. Prescribers make well-informed and safe prescribing decisions based on personal medication records contributed by patients. MyRxPad is thus the vehicle for collaborations with patients using MyMedicationList (MML). Integration with personal medication records in the context of e-prescribing is thus enabled. We present our experience in applying RxNorm in an e-prescribing setting: using standard names and codes to capture prescribed medication as well as extracting information from RxNorm to support medication-related clinical decision.

Opioid-Prescribing Patterns of Emergency Physicians and Risk of Long-Term Use

2017-01-01

BACKGROUND Increasing overuse of opioids in the United States may be driven in part by physician prescribing. However, the extent to which individual physicians vary in opioid prescribing and the implications of that variation for long-term opioid use and adverse outcomes in patients are unknown. METHODS We performed a retrospective analysis involving Medicare beneficiaries who had an index emergency department visit in the period from 2008 through 2011 and had not received prescriptions for opioids within 6 months before that visit. After identifying the emergency physicians within a hospital who cared for the patients, we categorized the physicians as being high-intensity or low-intensity opioid prescribers according to relative quartiles of prescribing rates within the same hospital. We compared rates of long-term opioid use, defined as 6 months of days supplied, in the 12 months after a visit to the emergency department among patients treated by high-intensity or low-intensity prescribers, with adjustment for patient characteristics. RESULTS Our sample consisted of 215,678 patients who received treatment from low-intensity prescribers and 161,951 patients who received treatment from high-intensity prescribers. Patient characteristics, including diagnoses in the emergency department, were similar in the two treatment groups. Within individual hospitals, rates of opioid prescribing varied widely between low-intensity and high-intensity prescribers (7.3% vs. 24.1%). Long-term opioid use was significantly higher among patients treated by high-intensity prescribers than among patients treated by low-intensity prescribers (adjusted odds ratio, 1.30; 95% confidence interval, 1.23 to 1.37; P<0.001); these findings were consistent across multiple sensitivity analyses. CONCLUSIONS Wide variation in rates of opioid prescribing existed among physicians practicing within the same emergency department, and rates of long-term opioid use were increased among patients who had

Prescribing psychotropic drugs to adults with an intellectual disability

SUMMARY Mental illness is common in people with intellectual disability. They may also have physical health problems which can affect their mental state. Difficulties in communication can contribute to mental health problems being overlooked. These may present with changes in behaviour. Psychological management is usually preferable to prescribing psychotropic drugs. Behavioural approaches are the most appropriate way to manage challenging behaviour. If a drug is considered, prescribers should complete a thorough diagnostic assessment, exclude physical and environmental contributions to symptoms, and consider medical comorbidities before prescribing. Where possible avoid psychotropics with the highest cardiometabolic burden. Prescribe the minimum effective dose and treatment length, and regularly monitor drug efficacy and adverse effects. There is insufficient evidence to support the use of psychotropics for challenging behaviour. They should be avoided unless the behaviour is severe and non-responsive to other treatments.

Among pediatricians, perceived knowledge of efficacy, tolerability, dosing, and side effects of antidepressants represent significant sources of variability in the use of these medications in youth with depressive and anxiety disorders. Importantly, the qualitative factors that relate to varying levels of comfort with antidepressants and willingness to prescribe are poorly understood. Using a mixed-methods approach, in-depth interviews were conducted with community-based and academic medical center-based pediatricians (N = 14). Interviews were audio recorded and iteratively coded; themes were then generated using inductive thematic analysis. The relationship between demographic factors, knowledge of antidepressants, dosing, and side effects, as well as prescribing likelihood scores for depressive disorders, anxiety disorders or co-morbid anxiety and depressive disorders, were evaluated using mixed models. Pediatricians reported antidepressants to be effective and well-tolerated. However, the likelihood of individual physicians initiating an antidepressant was significantly lower for anxiety disorders relative to depressive disorders with similar functional impairment. Pediatricians considered symptom severity/functional impairment, age and the availability of psychotherapy as they considered prescribing antidepressants to individual patients. Antidepressant choice was related to the physician׳s perceived knowledge and comfort with a particular antidepressant, financial factors, and the disorder-specific evidence base for that particular medication and consultation with mental health practitioners. Pediatricians noted similar efficacy and tolerability profiles for antidepressants in youth with depressive disorders and anxiety disorders, but tended to utilize "therapy first" approaches for anxiety disorders relative to depressive disorders. Parental and family factors that influenced prescribing of antidepressants by pediatricians included parental ambivalence

Objectives. To evaluate knowledge and prescribing changes following a 2-month public health detailing campaign (one-to-one educational visits) about judicious opioid analgesic prescribing conducted among health care providers in Staten Island, New York City, in 2013. Methods. Three detailing campaign recommendations were (1) a 3-day supply of opioids is usually sufficient for acute pain, (2) avoid prescribing opioids for chronic noncancer pain, and (3) avoid high-dose opioid prescriptions. Evaluation consisted of a knowledge survey, and assessing prescribing rates and median day supply per prescription. Prescribing data from the 3-month period before the campaign were compared with 2 sequential 3-month periods after the campaign. Results. Among 866 health care providers visited, knowledge increased for all 3 recommendations (P < .01). After the campaign, the overall prescribing rate decreased similarly in Staten Island and other New York City counties (boroughs), but the high-dose prescribing rate decreased more in Staten Island than in other boroughs (P < .01). Median day supply remained stable in Staten Island and increased in other boroughs. Conclusions. The public health detailing campaign improved knowledge and likely prescribing practices and could be considered by other jurisdictions to promote judicious opioid prescribing. PMID:27400353

Pharmaceutical marketing research and the prescribing physician.

PubMed

Greene, Jeremy A

2007-05-15

Surveillance of physicians' prescribing patterns and the accumulation and sale of these data for pharmaceutical marketing are currently the subjects of legislation in several states and action by state and national medical associations. Contrary to common perception, the growth of the health care information organization industry has not been limited to the past decade but has been building slowly over the past 50 years, beginning in the 1940s when growth in the prescription drug market fueled industry interest in understanding and influencing prescribing patterns. The development of this surveillance system was not simply imposed on the medical profession by the pharmaceutical industry but was developed through the interactions of pharmaceutical salesmen, pharmaceutical marketers, academic researchers, individual physicians, and physician organizations. Examination of the role of physicians and physician organizations in the development of prescriber profiling is directly relevant to the contemporary policy debate surrounding this issue.

Prokinetics prescribing in paediatrics: evidence on cisapride, domperidone, and metoclopramide.

Domperidone and metoclopramide are prokinetics commonly prescribed off-label to infants and younger children in an attempt to treat gastro-oesophageal reflux symptoms. Another prokinetic drug, cisapride, was used but withdrawn in 2000 in the United Kingdom because of serious arrhythmic adverse events. Medicines and Healthcare Products Regulatory Agency issued safety warnings for domperidone in May 2012 and restricted its indications. We report here national primary care prescribing trends and safety signals of these drugs in children. We used data from the General Practice Research Database between 1990 and 2006 for children <18 years. Descriptive statistics and Poisson regressions were performed to characterise prescribing trends. We examined safety signals in nested case-control studies. The proportion of children <2 years old being prescribed one of the medications doubled during the study period. Prescriptions of domperidone increased 10-fold, mainly following the withdrawal of cisapride in 2000. Prescriptions of metoclopramide did not change significantly. Despite the increase in prescriptions of domperidone, no new safety signals were identified. These data showed dramatic changes in prescribing of cisapride and domperidone despite the lack of good-quality supporting evidence. It is possible that these prescribing trends were influenced by published guidelines. Even if produced without robust efficacy and safety evidence, published guidelines can influence clinicians and consequently affect prescribing. Therefore, improving the evidence base on prokinetics to inform future guidelines is vital. The lack of new safety signals during this period would support the development of suitable powered clinical studies.

What use is generic prescribing?

PubMed Central

Archer, Michael

1985-01-01

The dispensing of generic preparations at four dispensing chemist shops was investigated by means of a questionnaire. Certain generic prescriptions result in the dispensing of proprietary products despite the existence of generic preparations, and the pharmacist may be reimbursed for the cost of the proprietary drug which has been dispensed. Not all generic prescriptions result in the dispensing of cheaper drugs because of the methods of payment to chemists. If doctors write more generic prescriptions there will ultimately be more dispensing of generic products. Even in the case of drugs still under patent, prescribing by generic name should be encouraged. The savings achieved by generic prescribing are to some extent at the cost of the dispensing chemists. The method and scale of payments for dispensing requires urgent review. PMID:4032358

Azole-resistant Aspergillus fumigatus harboring the TR34/L98H or TR46/Y121F/T289A alterations is increasingly found in Europe and Asia. Here, we present the first clinical cases of TR46/Y121/T289A and three cases of TR34/L98H outside the cystic fibrosis (CF) population in Denmark and the results of environmental surveys. Four patients (2012 to 2014) with 11 A. fumigatus and 4 Rhizomucor pusillus isolates and 239 soil samples (spring 2010 and autumn 2013, respectively) with a total of 113 A. fumigatus isolates were examined. Aspergillus isolates were screened for azole resistance using azole-containing agar. Confirmatory susceptibility testing was done using the EUCAST microbroth dilution EDEF 9.1 reference method. For relevant A. fumigatus isolates, CYP51A sequencing and microsatellite genotyping were performed. Three patients harbored TR34/L98H isolates. Two were azole naive at the time of acquisition and two were coinfected with wild-type A. fumigatus or R. pusillus isolates, complicating and delaying diagnosis. The TR46/Y121F/T289A strain was isolated in 2014 from a lung transplant patient. Genotyping indicated that susceptible and resistant Aspergillus isolates were unrelated and that no transmission between patients occurred. Azole resistance was not detected in any of the 113 soil isolates. TR34/L98H and TR46/Y121F/T289A alterations appear to be emerging in the clinical setting in Denmark and now involve azole-naive patients. Two recent soil-sampling surveys in Denmark were unable to indicate any increased prevalence of azole-resistant A. fumigatus in the environment. These findings further support the demand for real-time susceptibility testing of all clinically relevant isolates and for studies investigating the seasonal variation and ecological niches for azole-resistant environmental A. fumigatus.

Despite guidelines and campaigns to change prescribing behavior, General Practitioners (GPs) continue to overprescribe benzodiazepines (BZDs). New approaches to improve prescribing are needed. Using behavior change techniques and tailoring interventions to user characteristics are vital to promote behavior change. This study evaluated the impact of an e-module on factors known to determine BZD prescribing practice. A tailored e-module that focuses on avoiding initial BZD prescriptions (and using psychological interventions as an alternative) was developed and offered to GPs in vocational training. Three self-report assessments took place: at baseline, immediately after the module (short term) and at least six months after completion (long term). Assessed determinants include GPs' attitudes concerning treatment options, perceptions of the patient and self-efficacy beliefs. Readiness to adhere to prescribing guidelines was evaluated through assessing motivation, self-efficacy and implementability of non-pharmacological interventions. Changes in determinants were analyzed using the Wilcoxon signed-rank test. Changes in readiness to adhere to guidelines was analyzed using the nonparametric McNemar Bowker test. A desirable, significant and durable impact on determinants of BZD prescribing was observed. GPs (n = 121) underwent desirable changes in their attitudes, perceptions and self-efficacy beliefs and these changes remained significant months after the intervention. Barriers to using a non-pharmacological approach often cited in literature remained absent and were not highlighted by the intervention. Furthermore a significant impact on GPs' readiness to adhere to guidelines was observed. Participants reported change in their ability to cope with psychosocial consultations and to have tried using non-pharmacological interventions. Tailoring an e-intervention to target group (GPs) characteristics appears to be successful in promoting behavioral change in GPs

Yorkgitis, Brian K; Bryant, Elizabeth; Raygor, Desiree; Brat, Gabriel; Smink, Douglas S; Crandall, Marie

Opioid abuse and misuse is a public health crisis. A national effort to reduce this phenomenon is ongoing. Residents represent a large pool of opioid prescribers but, are often not the target for opioid prescribing education (OPE). We developed a survey to assess current opioid prescribing practices and education among surgical residents. An Institutional Review Board and Association of Program Directors in Surgery approved survey was electronically mailed to surgical program directors (PDs). The survey included questions regarding residency type, location, number of graduates per year, perceived value of OPE, residency policy on prescribing outpatients controlled substances, presence of OPE, and preferred method of OPE. A total of 248 PDs were e-mailed the survey with 110 complete responses (44.4%). Of all 104 (94.5%) allow residents to prescribe outpatient opioids with 24 (23.1%) limiting the opioid class prescribed. A total of 29 (27.9%) programs require residents to obtain their own Drug Enforcement Administration registration. Only 22 (20.0%) programs had in place mandatory OPE, 7 (6.4%) PDs were unsure if OPE was a mandatory educational requirement. Furthermore, 70 (79.5%) of programs currently without OPE are considering adding it. Didactic lecture (18, 81.8%) is the most common modality for OPE. The mode time dedicated to OPE was 1 hour. When PDs were asked about which method would be best to deliver OPE, the most common response was case-based scenarios (39, 35.5%). Bivariate statistics were performed and no association was found between OPE and program characteristics'. Most surgical residency programs allow residents to prescribe outpatient opioids, very few require OPE. The most common method of OPE was didactic lectures. To enhance a resident's knowledge in prescribing opioids, programs should incorporate OPE into their curriculum. Copyright © 2017 Association of Program Directors in Surgery.

Changing antibiotic prescribing by educational marketing.

PubMed

Landgren, F T; Harvey, K J; Mashford, M L; Moulds, R F; Guthrie, B; Hemming, M

A controlled cross-over study in 12 Victorian public hospitals was performed to examine the power of marketing techniques in influencing prescribing. The targeted prescribing behaviour was the use of antibiotic prophylaxis in surgery, and the criteria for judging the appropriateness of therapy were its duration and timing, as are detailed in the fourth edition of the booklet Antibiotic guidelines. The first intervention was mounted in 1985 in six hospitals (two metropolitan teaching hospitals, one suburban general hospital and three rural hospitals), and six matched hospitals acted as control hospitals. One year later, the intervention was mounted in the six hospitals that previously had been the control hospitals. The interventional campaign consisted of material that was similar to that which is used by the pharmaceutical industry, including an "academic" representative. Its effect was assessed by audits that were performed before and after the first interventional campaign and again, one year later, after the second interventional campaign. The proportion of antibiotic courses that were assessed as satisfactory in terms of duration increased significantly after the first campaign in the hospitals where the intervention was mounted. No significant changes in prescribing occurred in the control hospitals. In the hospitals which were control hospitals in 1985, and in which the intervention occurred in 1986, the proportion of antibiotic courses that were assessed as satisfactory also increased significantly after the interventional campaign. A fall-off in performance occurred during the 12 months after the campaign in the 1985-interventional hospitals. Calculated cost savings more than outweighed the costs of the campaign. We conclude that inappropriate prescribing behaviour in hospitals can be modified successfully by educational marketing techniques.

Controlled Substance Prescribing Patterns--Prescription Behavior Surveillance System, Eight States, 2013.

PubMed

Paulozzi, Leonard J; Strickler, Gail K; Kreiner, Peter W; Koris, Caitlin M

Drug overdose is the leading cause of injury death in the United States. The death rate from drug overdose in the United States more than doubled during 1999-2013, from 6.0 per 100,000 population in 1999 to 13.8 in 2013. The increase in drug overdoses is attributable primarily to the misuse and abuse of prescription drugs, especially opioid analgesics, sedatives/tranquilizers, and stimulants. Such drugs are prescribed widely in the United States, with substantial variation by state. Certain patients obtain drugs for nonmedical use or resale by obtaining overlapping prescriptions from multiple prescribers. The risk for overdose is directly associated with the use of multiple prescribers and daily dosages of >100 morphine milligram equivalents (MMEs) per day. 2013. The Prescription Behavior Surveillance System (PBSS) is a public health surveillance system that allows public health authorities to characterize and quantify the use and misuse of prescribed controlled substances. PBSS began collecting data in 2012 and is funded by CDC and the Food and Drug Administration. PBSS uses standard metrics to measure prescribing rates per 1,000 state residents by demographic variables, drug type, daily dose, and source of payment. Data from the system can be used to calculate rates of misuse by certain behavioral measures such as use of multiple prescribers and pharmacies within specified time periods. This report is based on 2013 de-identified data (most recent available) that represent approximately one fourth of the U.S. Data were submitted quarterly by prescription drug monitoring programs (PDMPs) in eight states (California, Delaware, Florida, Idaho, Louisiana, Maine, Ohio, and West Virginia) that routinely collect data on every prescription for a controlled substance to help law enforcement and health care providers identify misuse or abuse of such drugs. In all eight states, opioid analgesics were prescribed approximately twice as often as stimulants or benzodiazepines

Biological information frequently manifests its "meaning" through instruction or actual production of formal bio-function. Such information is called prescriptive information (PI). PI programs organize and execute a prescribed set of choices. Closer examination of this term in cellular systems has led to a dichotomy in its definition suggesting both prescribed data and prescribed algorithms are constituents of PI. This paper looks at this dichotomy as expressed in both the genetic code and in the central dogma of protein synthesis. An example of a genetic algorithm is modeled after the ribosome, and an examination of the protein synthesis process is used to differentiate PI data from PI algorithms.

Assessment of lnternational Space Station (ISS) Lithium-ion Battery Thermal Runaway (TR)

NASA Technical Reports Server (NTRS)

Graika, Jason

2017-01-01

This task was developed in the wake of the Boeing 787 Dreamliner lithium-ion battery TR incidents of January 2013 and January 2014. The Electrical Power Technical Discipline Team supported the Dreamliner investigations and has followed up by applying lessons learned to conduct an introspective evaluation of NASA's risk of similar incidents in its own lithium-ion battery deployments. This activity has demonstrated that historically NASA, like Boeing and others in the aerospace industry, has emphasized the prevention of TR in a single cell within the battery (e.g., cell screening) but has not considered TR severity-reducing measures in the event of a single-cell TR event. center dotIn the recent update of the battery safety standard (JSC 20793) to address this paradigm shift, the NASA community included requirements for assessing TR severity and identifying simple, low-cost severity reduction measures. This task will serve as a pathfinder for meeting those requirements and will specifically look at a number of different lithium-ion batteries currently in the design pipeline within the ISS Program batteries that, should they fail in a Dreamliner-like incident, could result in catastrophic consequences. This test is an abuse test to understand the heat transfer properties of the cell and ORU in thermal runaway, with radiant barriers in place in a flight like test in on orbit conditions. This includes studying the heat flow and distribution in the ORU. This data will be used to validate the thermal runaway analysis. This test does not cover the ambient pressure case. center dotThere is no pass/ fail criteria for this test.

Teen pregnancy and sexually transmitted infection (STI) rates continue to be significant public health problems in the United States. While general pediatricians are in a unique position to improve these issues by addressing contraception with their adolescent patients, there are no data describing their current prescribing patterns. This study sought to elucidate the beliefs and prescribing patterns of general pediatricians and pediatrics residents and to distinguish whether these were affected by practice setting, level of training, or gender. General pediatricians and pediatrics residents affiliated with Lurie Children's Hospital in Chicago, IL, were asked to complete a survey regarding adolescent contraception. Questions were related to obtaining information about contraception, contraceptive counseling, knowledge of contraceptive methods, prescribing patterns of contraceptives, and concerns about individual contraceptive methods. 120 physicians of an eligible 411 physicians participated in this study (29%). 79% of participants had prescribed at least 1 contraceptive method. The most commonly prescribed method was oral contraceptive pills at 72%. We noted few differences in prescribing patterns based on above criteria. Numerous misconceptions existed among participants, including a high rate of concern about infertility with IUD use (29% among physicians who prescribed at least 1 method of contraception). General pediatricians can improve their rates of prescribing contraception to adolescents, and could utilize more of the approved methods. One way to do so may be to implement educational interventions among general pediatricians. Copyright © 2013 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc.

Over 50,000 non-medical healthcare professionals across the United Kingdom now have prescribing capabilities. However, there is no evidence available with regards to the extent to which non-medical prescribing (NMP) has been implemented within organisations across a strategic health authority (SHA). The aim of the study was to provide an overview of NMP across one SHA. NMP leads across one SHA were asked to supply the email addresses of NMPs within their organisation. One thousand five hundred and eighty five NMPs were contacted and invited to complete an on-line descriptive questionnaire survey, 883 (55.7%) participants responded. Data was collected between November 2010 and February 2011. The majority of NMPs were based in primary care and worked in a team of 2 or more. Nurse independent supplementary prescribers were the largest group (590 or 68.6%) compared to community practitioner prescribers (198 or 22.4%), pharmacist independent supplementary prescribers (35 or 4%), and allied health professionals and optometrist independent and/or supplementary prescribers (8 or 0.9%). Nearly all (over 90%) of nurse independent supplementary prescribers prescribed medicines. Approximately a third of pharmacist independent supplementary prescribers, allied health professionals, and community practitioner prescribers did not prescribe. Clinical governance procedures were largely in place, although fewer procedures were reported by community practitioner prescribers. General practice nurses prescribed the most items. Factors affecting prescribing practice were: employer, the level of experience prior to becoming a non-medical prescriber, existence of governance procedures and support for the prescribing role (p < 0.001). NMP in this strategic health authority reflects national development of this relatively new role in that the majority of non-medical prescribers were nurses based in primary care, with fewer pharmacist and allied health professional prescribers.

Background Appropriate medication prescribing for nursing home residents remains a challenge. Objective The purpose of this study was to conduct a narrative review of the published literature describing randomized controlled trials that used interventions to improve suboptimal prescribing in nursing homes. Methods The PubMed, International Pharmaceutical Abstracts, and EMBASE databases were searched for articles published in the English language between January 1975 and December 2009, using the terms drug utilization, pharmaceutical services, aged, long-term care, nursing homes, prescribing, geriatrics, and randomized controlled trial. A manual search of the reference lists of identified articles and the authors’ files, book chapters, and recent review articles was also conducted. Abstracts and posters from meetings were not included in the search. Studies were included if they: (1) had a randomized controlled design; (2) had a process measure outcome for quality of prescribing or a distal outcome measure for medication-related adverse patient events; and (3) involved nursing home residents. Results Eighteen studies met the inclusion criteria for this review. Seven of those studies described educational approaches using various interventions (eg, outreach visits) and measured suboptimal prescribing in different manners (eg, adherence to guidelines). Two studies described computerized decision-support systems to measure the intervention’s impact on adverse drug events (ADEs) and appropriate drug orders. Five studies described clinical pharmacist activities, most commonly involving a medication review, and used various measures of suboptimal prescribing, including a measure of medication appropriateness and the total number of medications prescribed. Two studies each described multidisciplinary and multifaceted approaches that included heterogeneous interventions and measures of prescribing. Most (15/18; 83.3%) of these studies reported statistically significant

Objectives To evaluate the prescribing patterns of compound mixtures of cough and cold liquid medications, known as mezclitas, which are prescribed to patients with respiratory illnesses in Puerto Rico. Secondary objectives include assessing the potential safety of these mixtures and patients’ perception of them. Methods Using a cross sectional study approach, a convenience sample was obtained from five pharmacies in Puerto Rico, from October 2008 to October 2009. Patients were asked to complete a 9-item questionnaire of demographic information, in addition to their mezclita prescription data. Results The mean age of patients was 43 years with a range of less than 12 months to 101 years. For children ≤ four years of age, 71% were prescribed cough and cold medications. Sixty-four percent of the prescriptions were given to females. The most prevalent ingredient employed was guaifenesin, which appeared in about 77% of the mezclitas. ‘Common cold’ was the principal diagnosis for 62% of the prescriptions, of which 75% of these prescriptions contained a corticosteroid and 17% contained a beta2 agonist bronchodilator. The top medical prescribing specialty was general medicine (51%). Thirty-eight percent of hypertensive patients were prescribed a decongestant. The majority of diabetic patients (60%) were dispensed a corticosteroid. Most (74%) patients reported that they had a rapid and good response to their mezclita. Conclusion Mezclitas were most commonly prescribed for acute symptoms of upper respiratory illness by general physicians, despite possible side effects. This study suggests that the prescription patterns of mezclitas do not always consider evidence-based medicine treatment guidelines. PMID:23038886

Background Pain is a frequent symptom among patients in the hospital. Pain management is a key quality indicator for hospitals and hospitalists are encouraged to frequently assess and treat pain. Optimal opioid prescribing, described as safe, patient-centered and informed opioid prescribing, may be at odds with the priorities of current hospital care, which focuses on patient-reported pain control rather than the potential long-term consequences of opioid use. Objective We aimed to understand physicians’ attitudes, beliefs and practices towards opioid prescribing during hospitalization and discharge. Design In-depth, semi-structured interviews Setting Two university hospitals, a safety-net hospital, a Veterans Affairs hospital, and a private hospital located in Denver, Colorado or Charleston, South Carolina. Participants Hospitalists (N=25) Measurements We systematically analyzed transcribed interviews and identified emerging themes using a team-based mixed inductive and deductive approach. Results Although hospitalists felt confident in their ability to control acute pain using opioid medications, they perceived limited success and satisfaction when managing acute exacerbations of chronic pain with opioids. Hospitalists recounted negative sentinel events which altered opioid prescribing practices in both the hospital setting and at the time of hospital discharge. Hospitalists described prescribing opioids as a pragmatic tool to facilitate hospital discharges or prevent readmissions. At times, this left them feeling conflicted about how this practice could impact the patient over the long term. Conclusions Strategies to provide adequate pain relief to hospitalized patients, which allow hospitalists to safely and optimally prescribe opioids while maintaining current standards of efficiency, are urgently needed.

Transcriptional gene silencing (TGS) can serve as an innate immunity against invading DNA viruses throughout Eukaryotes. Geminivirus code for TrAP protein to suppress the TGS pathway. Here, we identified an Arabidopsis H3K9me2 histone methyltransferase, Su(var)3-9 homolog 4/Kryptonite (SUVH4/KYP), as a bona fide cellular target of TrAP. TrAP interacts with the catalytic domain of KYP and inhibits its activity in vitro. TrAP elicits developmental anomalies phenocopying several TGS mutants, reduces the repressive H3K9me2 mark and CHH DNA methylation, and reactivates numerous endogenous KYP-repressed loci in vivo. Moreover, KYP binds to the viral chromatin and controls its methylation to combat virus infection. Notably, kyp mutants support systemic infection of TrAP-deficient Geminivirus. We conclude that TrAP attenuates the TGS of the viral chromatin by inhibiting KYP activity to evade host surveillance. These findings provide new insight on the molecular arms race between host antiviral defense and virus counter defense at an epigenetic level.

Specific intestinal microbiota has been shown to induce Foxp3(+) regulatory T cell development. However, it remains unclear how development of another regulatory T cell subset, Tr1 cells, is regulated in the intestine. Here, we analyzed the role of two probiotic strains of intestinal bacteria, Lactobacillus casei and Bifidobacterium breve in T cell development in the intestine. B. breve, but not L. casei, induced development of IL-10-producing Tr1 cells that express cMaf, IL-21, and Ahr in the large intestine. Intestinal CD103(+) dendritic cells (DCs) mediated B. breve-induced development of IL-10-producing T cells. CD103(+) DCs from Il10(-/-), Tlr2(-/-), and Myd88(-/-) mice showed defective B. breve-induced Tr1 cell development. B. breve-treated CD103(+) DCs failed to induce IL-10 production from co-cultured Il27ra(-/-) T cells. B. breve treatment of Tlr2(-/-) mice did not increase IL-10-producing T cells in the colonic lamina propria. Thus, B. breve activates intestinal CD103(+) DCs to produce IL-10 and IL-27 via the TLR2/MyD88 pathway thereby inducing IL-10-producing Tr1 cells in the large intestine. Oral B. breve administration ameliorated colitis in immunocompromised mice given naïve CD4(+) T cells from wild-type mice, but not Il10(-/-) mice. These findings demonstrate that B. breve prevents intestinal inflammation through the induction of intestinal IL-10-producing Tr1 cells.

Objective To examine gender differences in prescribing of antipsychotic medications (APMs) according to their liability for weight gain and other metabolic side effects. Method We identified 4,510 patients with schizophrenia or bipolar disorders receiving usual care in a VA healthcare network in the U.S. mid-Atlantic region who initiated treatment with an APM between 10/2006 and 9/2011. We used multivariable logistic regression to examine gender differences in the likelihood of incident prescription of APMs with low versus medium/high metabolic risk, adjusting for fiscal year of prescribing and selected Veteran demographic, mental health, and physical health characteristics. Results Overall, 58% of women were prescribed an APM with a low risk of metabolic side effects compared to 45% of men (p < 0.001). In multivariable analysis, women Veterans were 1.47 times as likely as men to be prescribed a low metabolic risk APM (95% CI: 1.26–1.73, p<0.001). Several demographic and clinical covariates were also independently related to prescribing of APMs by level of metabolic risk. Conclusions The results may suggest that prescribing choices for APMs by VA mental health prescribers and female Veterans reflect a growing awareness of the potential adverse health consequences of these treatments in women.

Antibiograms have effectively improved antibiotic prescribing in acute-care settings; however, their effectiveness in skilled nursing facilities (SNFs) is currently unknown. To develop SNF-specific antibiograms and identify opportunities to improve antibiotic prescribing. Cross-sectional and pretest-posttest study among residents of 3 Maryland SNFs. Antibiograms were created using clinical culture data from a 6-month period in each SNF. We also used admission clinical culture data from the acute care facility primarily associated with each SNF for transferred residents. We manually collected all data from medical charts, and antibiograms were created using WHONET software. We then used a pretest-posttest study to evaluate the effectiveness of an antibiogram on changing antibiotic prescribing practices in a single SNF. Appropriate empirical antibiotic therapy was defined as an empirical antibiotic choice that sufficiently covered the infecting organism, considering antibiotic susceptibilities. We reviewed 839 patient charts from SNF and acute care facilities. During the initial assessment period, 85% of initial antibiotic use in the SNFs was empirical, and thus only 15% of initial antibiotics were based on culture results. Fluoroquinolones were the most frequently used empirical antibiotics, accounting for 54.5% of initial prescribing instances. Among patients with available culture data, only 35% of empirical antibiotic prescribing was determined to be appropriate. In the single SNF in which we evaluated antibiogram effectiveness, prevalence of appropriate antibiotic prescribing increased from 32% to 45% after antibiogram implementation; however, this was not statistically significant ([Formula: see text]). Implementation of antibiograms may be effective in improving empirical antibiotic prescribing in SNFs.

Few studies have examined the variations among individual physicians in prescribing antipsychotics for schizophrenia. This study examined clinical practice variations in the route and dosage of antipsychotic medication prescribed for inpatients with schizophrenia by 11 different psychiatrists. The sample consisted of 130 patients with a DSM-III-R diagnosis of schizophrenia who had received inpatient care at a state hospital or Veterans Affairs medical center in the southeastern United States in 1992-1993. Mixed-effects regression models were developed to explore the influence of individual physicians and hospitals on route of antipsychotic administration (oral or depot) and daily antipsychotic dose, controlling for patient case-mix variables (age, race, sex, duration of illness, symptom severity, and substance-abuse diagnosis). The average daily antipsychotic dose was 1092 +/- 892 chlorpromazine mg equivalents. Almost half of the patients (48%) were prescribed doses above or below the range recommended by current practice guidelines. The proportion of patients prescribed depot antipsychotics was significantly different at the 2 hospitals, as was the antipsychotic dose prescribed at discharge. Individual physicians and patient characteristics were not significantly associated with prescribing practices. These data, which were obtained before clinical practice guidelines were widely disseminated, provide a benchmark against which to examine more current practice variations in antipsychotic prescribing. The results raise several questions about deviations from practice guidelines in the pharmacological treatment of schizophrenia. To adequately assess quality and inform and possibly further develop clinical practice guideline recommendations for schizophrenia, well-designed research studies conducted in routine clinical settings are needed.

Prescribed burning is commonly used to reduce the risk of severe wildfire. However, further information about the associated environmental effects is required to help forest managers select the most appropriate treatment. To address this question, we evaluated if fire severity during spring prescribed burning significantly affects the resprouting ability of two common shrub species in shrubland under a Mediterranean climate in NW Spain. Fire behaviour and temperatures were recorded in tagged individuals of Erica australis and Pterospartum tridentatum during prescribed burning. The number and length of resprouted shoots were measured three times (6, 12 and 18 months) after the prescribed burning. The influence of a series of fire severity indicators on some plant resprouting vigour parameters was tested by canonical correlation analysis. Six months and one year after prescribed burning, soil burn severity (measured by the absolute reduction in depth of the organic soil layer, maximum temperatures in the organic soil layer and the mineral soil surface during burning and the post-fire depth of the organic soil layer) reduced the resprouting vigour of E. australis and P. tridentatum. In contrast, direct measurements of fire effects on plants (minimum branch diameter, duration of temperatures above 300 °C in the shrub crown and fireline intensity) did not affect the post-fire plant vigour. Soil burn severity during spring prescribed burning significantly affected the short-term resprouting vigour in a mixed heathland in Galicia. The lack of effects eighteen months after prescribed burning indicates the high resilience of these species and illustrates the need to conciliate fire prevention and conservation goals.

A newly organic capacitor was conceived with a variable capacitance using the inverse piezoelectric effect. The device consists of two parallel plates of carbon nanotubes (CNTs), known for their large surface area, high sensitivity and high electric conductivity, separated by a thin film of a dielectric layer of Polyinylidene fluoride and trifluoroehtylene (P(VDF-TrFE)) promising material for piezoelectric and ferroelectric properties. The obtained architecture is the CNT/PVDF-TrFE/CNT capacitor device. In this study, an ultra-thin film of P(VDF-TrFE) (54/46) with thickness of 20 nm was elaborated on highly oriented pyrolytic graphite (HOPG) by spin-coating. The morphology of the ultra-thin film and the mechanical behavior of CNT/P(VDF-TrFE)/CNT system were studied using the atomic force microscopy (AFM) combined with a lock-in amplifier in contact mode. All changes in applied voltage induce a change in thin film thickness according to the inverse piezoelectric effect that affect, consequently the capacitance. The results showed that the ratio of capacitance change ΔC to initial capacitance C0 is ΔC/C0=5%. This value is sufficient to use P(VDF-TrFE) as variable organic capacitor.

Do prescribed prompts prime sensemaking during group problem solving?

Many researchers and textbooks have promoted the use of rigid prescribed strategies for encouraging development of expert-like problem-solving behavior in novice students. The University of British Columbia's introductory algebra-based course for non-physics majors uses Context-Rich problems with a prescribed six-step strategy. We have coded audio recordings of group problem-solving sessions to analyze students' epistemological framing based on the implicit goal of their discussions. By treating the goal of "understanding the physics of the situation" as sensemaking, we argue that prescribed problem-solving prompts are not sufficient to induce subsequent sensemaking discussion.

Prescribing contraception for young women.

Since 2002, specially qualified nursing sisters and midwives have had the right to prescribe contraceptive pills for women aged 16 to 19. This arrangement has since been expanded to cover hormonal contraception, with the exception of the hormonal coil. The purpose of this study is to evaluate the arrangement. The prescription register uses pseudonyms and contains a number of facts about user, medication and prescriber. A database of women born in 1989, totalling 29,821, has been designed as a unit for analysis. 75 and 79% of the cohort had filled at least one prescription for contraceptive pills or hormonal contraception by the end of the calendar year in which they turned 19. Almost 12% had filled at least one prescription for the mini-pill, while far fewer had filled prescriptions for vaginal hormone ring, contraceptive injection, contraceptive patch or hormonal coil. Doctors issued two third of the prescriptions. Nursing sisters wrote more prescriptions than doctors for the age group 17-18. The period of time during which they had been using the contraceptive pill and the mini-pill did not depend on who prescribed them. The fact that close to 80% of the cohort born in 1989 has filled at least one prescription for hormonal contraception shows that there is a high degree of awareness about preventing unplanned pregnancy. Extending the right to write prescriptions to nurses and midwives has increased the availability of contraception, and young women are taking advantage of this option.

Public concern about the prescription of hypnosedative drugs (mostly benzodiazepines) led to a controlled trial of an educational intervention to promote rational prescribing by general practitioners (GPs). This paper describes the educational intervention and its process evaluation. In urban and rural New South Wales 137 GPs were visited in office hours by a GP or pharmacist who had undergone communication skills training. Material offered to GPs included relaxation tapes and a booklet of problem-orientated management guidelines. The interview had three stages: rapport was established, then educational material was introduced and finally the visitor sought the doctor's agreement to review five patients on long-term benzodiazepines. The visits were well received. Several measures were composed to reflect doctors' motivation and interest in non-drug management; there was virtually no correlation between any of these process measures and the trial outcome: a change in prescribing behaviour. Self-rating of benzodiazepine prescribing greatly underestimated actual self-reported incidents of prescribing. We interpret this as a reminder that we do not always do what we mean to do, and that we do not always do what we think we do.

Factors influencing pharmacists’ adoption of prescribing: qualitative application of the diffusion of innovations theory

Background In 2007, Alberta became the first Canadian jurisdiction to grant pharmacists a wide range of prescribing privileges. Our objective was to understand what factors influence pharmacists’ adoption of prescribing using a model for the Diffusion of Innovations in healthcare services. Methods Pharmacists participated in semi-structured telephone interviews to discuss their prescribing practices and explore the facilitators and barriers to implementation. Pharmacists working in community, hospital, PCN, or other settings were selected using a mix of random and purposive sampling. Two investigators independently analyzed each transcript using an Interpretive Description approach to identify themes. Analyses were informed by a model explaining the Diffusion of Innovations in health service organizations. Results Thirty-eight participants were interviewed. Prescribing behaviours varied from non-adoption through to product, disease, and patient focused use of prescribing. Pharmacists’ adoption of prescribing was dependent on the innovation itself, adopter, system readiness, and communication and influence. Adopting pharmacists viewed prescribing as a legitimization of previous practice and advantageous to instrumental daily tasks. The complexity of knowledge required for prescribing increased respectively in product, disease and patient focused prescribing scenarios. Individual adopters had higher levels of self-efficacy toward prescribing skills. At a system level, pharmacists who were in practice settings that were patient focused were more likely to adopt advanced prescribing practices, over those in product-focused settings. All pharmacists stated that physician relationships impacted their prescribing behaviours and individual pharmacists’ decisions to apply for independent prescribing privileges. Conclusions Diffusion of Innovations theory was helpful in understanding the multifaceted nature of pharmacists’ adoption of prescribing. The characteristics

Patient adherence to prescribed antimicrobial drug dosing regimens.

The aim of this article is to review current knowledge about the clinical impact of patients' variable adherence to prescribed anti-infective drug dosing regimens, with the aim of renewing interest and exploration of this important but largely neglected area of therapeutics. Central to the estimation of a patient's adherence to a prescribed drug regimen is a reliably compiled drug dosing history. Electronic monitoring methods have emerged as the virtual 'gold standard' for compiling drug dosing histories in ambulatory patients. Reliably compiled drug dosing histories are consistently downwardly skewed, with varying degrees of under-dosing. In particular, the consideration of time intervals between protease inhibitor doses has revealed that ambulatory patients' variable execution of prescribed dosing regimens is a leading source of variance in viral response. Such analyses reveal the need for a new discipline, called pharmionics, which is the study of how ambulatory patients use prescription drugs. Properly analysed, reliable data on the time-course of patients' actual intake of prescription drugs can eliminate a major source of unallocated variance in drug responses, including the non-response that occurs and is easily misinterpreted when a patient's complete non-execution of a prescribed drug regimen is unrecognized clinically. As such, reliable compilation of ambulatory patients' drug dosing histories has the promise of being a key step in reducing unallocated variance in drug response and in improving the informational yield of clinical trials. It is also the basis for sound, measurement-guided steps taken to improve a patient's execution of a prescribed dosing regimen.

Reasons for suboptimal metformin prescribing are unclear, but may be due to perceived risk of lactic acidosis. The purpose of this study is to describe provider attitudes regarding metformin prescribing in various patient situations. An anonymous, electronic survey was distributed electronically to 76 health care providers across the nation. The 14-item survey contained demographic questions and questions related to prescribing of metformin for T2DM in various patient situations, including suboptimal glycemic control, alcohol use, history of lactic acidosis, and varying degrees of severity for certain health conditions, including renal and hepatic dysfunction, chronic obstructive pulmonary disease, and heart failure. There were a total of 100 respondents. For suboptimal glycemic control, most providers (75%) would increase metformin from 1500 to 2000 mg daily; however, 25% would add an alternate agent, such as a sulfonylurea (18%) or dipeptidyl peptidase-4 inhibitor (7%). Although 51% of providers would stop metformin based on serum creatinine thresholds, the remainder would rely on glomerular filtration rate thresholds of <60 mL/min (15%), <30 mL/min (33%), or <15 mL/min (1%) to determine when to stop metformin. For heart failure, 45% of providers would continue metformin as currently prescribed regardless of severity. Most providers would adjust metformin for varying severity of hepatic dysfunction (74%) and alcohol abuse (40%). Despite evidence supporting the cardiovascular benefits of metformin, provider attitudes toward prescribing metformin are suboptimal in certain patient situations and vary greatly by provider. © Copyright 2015 by the American Board of Family Medicine.

1. The effect of providing information about medicines by a short 'sales' interview between individual general practitioners and an 'academic representative' on prescribing was investigated. 2. The promotional campaign was designed to encourage a rational approach to prescribing of non-steroidal anti-inflammatory agents in an intervention group of 101 general practitioners selected at random from the Leeds Family Practitioner Committee (FPC). The remaining general practitioners in the Leeds FPC acted as a reference group. 3. The prescribing data for each group for 5 months immediately prior to and 5 months following intervention were compared. 4. Intervention produced a significant increase (P less than 0.005) in the prescribing cost of ibuprofen, the non-steroidal promoted as first choice agent, which was sustained for at least 5 months. 5. Prescribing of the second choice agent, piroxicam, decreased in the reference group but not in the intervention group. 6. There was a decrease in the average prescribing cost of pounds 6.60 per doctor per month in the intervention group compared with the reference group. PMID:1540493

To evaluate the validity and reliability of the Turkish version of the Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire for patients with Achilles tendinopathy. Fifty-five patients with a diagnosis of Achilles tendinopathy and 55 healthy subjects were included in the study. VISA-A questionnaires were translated and culturally adapted into Turkish. The final Turkish version (VISA-A-Tr) was tested for reliability on healthy individuals and patients. Tests for internal consistency, validity and structure were performed on 55 patients. The VISA-A-Tr showed good test-retest reliability (Pearson's r=0.99, p<0.001). The patients with Achilles tendinopathy had a significantly lower score (p<0.001) than the healthy individuals. The VISA-A-Tr score correlated significantly with the Stanish tendon grading system (Spearman's r=-0.86; p<0.001). The VISA-A-Tr is a valid and reliable tool for evaluating the severity of Achilles tendinopathy.

The prescribing behavior to prescribe high-priced drugs has been hypothesized to be related to the increasing drug expenditures in China, but little empirical evidence exists. The purpose of this study was to examine whether Chinese physicians, driven by financial incentives, tend to prescribe high-priced drugs. The 2000-2008 drug data in the Yangtze River Basin Hospitals' Drug Use Analysis System were analyzed to examine the prescription patterns of penicillins and cephalosporins in Shanghai. Among the top-100 drugs (by volume), cephalosporins cost as 1.1- 2.3 times as penicillins and their volume was 1.7-18.2 times. Revenues generated from prescribing cephalosporins were 3.4-24.2 times as those from prescribing penicillins. The tendency of prescribing relatively high-priced drugs was observed given the same chemical name, dosage, and specification but different trade names. Furthermore, high-priced drugs remained on the top-100 list with increasing volumes, while some lower-priced drugs exited from the list due to decreases in volumes. Facing the policy dilemmas, the Chinese government needs to implement a new financially rewarding system in which hospitals and physicians are able to achieve financial gains in a cost-effective way including prescribing similar drugs with lower prices. Reforming hospitals' payment methods is necessary and feasible to reshape financial incentives of healthcare providers. The combination of the global budget policy and financial incentive measures would be likely to change providers' prescribing behaviors towards a cost-effective direction.

The literature suggests that positive results of catheter urine cultures frequently lead to unnecessary antimicrobial prescribing, which therefore represents an important target for stewardship. To assess the appropriateness of antibiotic prescribing in response to the results of urine cultures from patients with indwelling urinary catheters. This retrospective study was conducted at a tertiary care centre and involved adults with indwelling urinary catheters from whom urine specimens were obtained for culture. Patients with positive or negative culture results were identified from microbiology laboratory reports. The medical records of consecutive patients were screened to select a sample of 80 inpatients (40 per group). Abstracted patient histories were independently evaluated by an expert panel of 3 infectious diseases consultants blinded to the decisions of prescribers and of fellow panelists. The primary end point was concordance of each patient's treatment decision (with respect to the indication) between the expert panel (based on majority agreement, i.e., at least 2 of the 3 expert panelists) and the prescriber. The secondary end points were unnecessary days of therapy and selected outcomes over a predefined period after urine was obtained for culture. A total of 591 charts were screened to generate the targeted number of patients. Baseline demographic characteristics were comparable for the 2 groups, except antibiotic exposure before urine collection was significantly more frequent for the group with negative culture results. The treatment decision was concordant in 40% (16/40) of the patients with a positive culture result and 85% (34/40) of those with a negative culture result (p < 0.001). The most common reason for discordance was administration of antibiotics when not indicated (23 of 24 patients with a positive result and 5 of 6 patients with a negative result), which accounted for 165 and 32 unnecessary days of therapy per 1000 inpatient

Prescribed fires as ecological surrogates for wildfires: A stream and riparian perspective

Forest managers use prescribed fire to reduce wildfire risk and to provide resource benefits, yet little information is available on whether prescribed fires can function as ecological surrogates for wildfire in fire-prone landscapes. Information on impacts and benefits of this management tool on stream and riparian ecosystems is particularly lacking. We used a beyond-BACI (Before, After, Control, Impact) design to investigate the effects of a prescribed fire on a stream ecosystem and compared these findings to similar data collected after wildfire. For 3 years after prescribed fire treatment, we found no detectable changes in periphyton, macroinvertebrates, amphibians, fish, and riparian and stream habitats compared to data collected over the same time period in four unburned reference streams. Based on changes in fuels, plant and litter cover, and tree scorching, this prescribed fire was typical of those being implemented in ponderosa pine forests throughout the western U.S. However, we found that the extent and severity of riparian vegetation burned was substantially lower after prescribed fire compared to nearby wildfires. The early-season prescribed fire did not mimic the riparian or in-stream ecological effects observed following a nearby wildfire, even in catchments with burn extents similar to the prescribed fire. Little information exists on the effects of long-term fire exclusion from riparian forests, but a "prescribed fire regime" of repeatedly burning upland forests while excluding fire in adjacent riparian forests may eliminate an important natural disturbance from riparian and stream habitats.

Prescribing medical cannabis in Canada: Are we being too cautious?

PubMed

Lake, Stephanie; Kerr, Thomas; Montaner, Julio

2015-04-30

There has been much recent discussion and debate surrounding cannabis in Canada, including the prescribing of medical cannabis for therapeutic purposes. Certain commentators - including the Canadian Medical Association (CMA) - have denounced the prescribing of cannabis for medical purposes due to a perceived lack of evidence related to the drug's efficacy, harms, and mechanism of action. In this commentary, we present arguments in favour of prescribing medical cannabis in Canada. We believe the anti-cannabis position taken by CMA and other commentators is not entirely evidence-based. Using the example of neuropathic pain, we present and summarize the clinical evidence surrounding smoked or vapourized cannabis, including recent evidence pertaining to the effectiveness of cannabis in comparison to existing standard pharmacotherapies for neuropathy. Further, we outline how the concerns expressed regarding cannabis' mechanism of action are inconsistent with current decision-making processes related to the prescribing of many common pharmaceuticals. Finally, we discuss potential secondary public health benefits of prescribing cannabis for pain-related disorders in Canada and North America.

We investigated the association between respiratory prescribing, air quality and deprivation in primary health care. Most previous studies have used data from secondary and tertiary care to quantify air pollution effects on exacerbations of asthma and chronic obstructive pulmonary disease (COPD). However, these outcomes capture patients who suffer from relatively severe symptoms. This is a population-based ecological study. We analysed respiratory medication (salbutamol) prescribed monthly by 63 primary care practices, UK. Firstly, we captured the area-wide seasonal variation in prescribing. Then, using the area-wide variation in prescribing as an offset, we built a mixed-effects model to assess the remaining variation in relation to air quality and demographic variables. An increase of 10 μg/m(3) in ambient PM10 was associated with an increase of 1% (95% CI: 0.1-2%) in salbutamol prescribing. An increase of 1 SD in income and employment deprivation was associated with an increase of 20.5% (95% CI: 8.8-33.4%) and 14.7% (95% CI: 4.3-26.2%) in salbutamol prescribing rate, respectively. The study provides evidence that monthly respiratory prescribing in primary care is a useful indicator of the extent to which air pollution exacerbates asthma and COPD symptoms. Respiratory prescribing was higher on deprived populations.

To facilitate the future implementation of an electronic prescribing system, this case study modeled prescription management processes in various primary care settings. The Vanderbilt e-prescribing design team conducted initial interviews with clinic managers, physicians and nurses, and then represented the sequences of steps carried out to complete prescriptions in activity diagrams. The diagrams covered outpatient prescribing for patients during a clinic visit and between clinic visits. Practice size, practice setting, and practice specialty type influenced the prescribing processes used. The model developed may be useful to others engaged in building or tailoring an e-prescribing system to meet the specific workflows of various clinic settings. PMID:16622168

Effects of prescribed fires on soil properties: A review.

Alcañiz, M; Outeiro, L; Francos, M; Úbeda, X

2018-02-01

Soils constitute one of the most valuable resources on earth, especially because soil is renewable on human time scales. During the 20th century, a period marked by a widespread rural exodus and land abandonment, fire suppression policies were adopted facilitating the accumulation of fuel in forested areas, exacerbating the effects of wildfires, leading to severe degradation of soils. Prescribed fires emerged as an option for protecting forests and their soils from wildfires through the reduction of fuels levels. However such fires can serve other objectives, including stimulating the regeneration of a particular plant species, maintaining biological diversity or as a tool for recovering grasslands in encroached lands. This paper reviews studies examining the short- and long- term impacts of prescribed fires on the physical, chemical and biological soil properties; in so doing, it provides a summary of the benefits and drawbacks of this technique, to help determine if prescribed fires can be useful for managing the landscape. From the study conducted, we can affirm that prescribed fires affects soil properties but differ greatly depending on soil initial characteristics, vegetation or type of fire. Also, it is possible to see that soil's physical and biological properties are more strongly affected by prescribed fires than are its chemical properties. Finally, we conclude that prescribed fires clearly constitute a disturbance on the environment (positive, neutral or negative depending on the soil property studied), but most of the studies reviewed report a good recovery and their effects could be less pronounced than those of wildfires because of the limited soil heating and lower fire intensity and severity.

2015-01-01

Purpose This research investigated the reported optometric prescribing criteria of Israeli optometrists. Methods An online questionnaire based on previous studies was distributed via email and social networking sites to optometrists in Israel. The questionnaire surveyed the level of refractive error at which respondents would prescribe for different types of refractive error at various ages with and without symptoms. Results 124 responses were obtained, yielding a response rate of approximately 12–22%, 92% of whom had trained in Israel. For all refractive errors, the presence of symptoms strongly influenced prescribing criteria. For example, for 10–20 year old patients the degree of hyperopia for which 50% of practitioners would prescribe is +0.75 D in the presence of symptoms but twice this value (+1.50 D) in the absence of symptoms. As might be expected, optometrists prescribed at lower degrees of hyperopia for older compared with younger patients. There was a trend for more experienced practitioners to be less likely to prescribe for lower degrees of myopia and presbyopia. Practitioner gender, country of training, the type of practice environment, and financial incentives were not strongly related to prescribing criteria. Conclusions The prescribing criteria found in this study are broadly comparable with those in previous studies and with published prescribing guidelines. Subtle indications suggest that optometrists may become more conservative in their prescribing criteria with experience. PMID:26520884

Electronic systems that facilitate prescribing, administration and dispensing of medicines (ePrescribing systems) are at the heart of international efforts to improve the safety, quality and efficiency of medicine management. Considering the initial costs of procuring and maintaining ePrescribing systems, there is a need to better understand how to accelerate and maximise the financial benefits associated with these systems. We sought to investigate how different sectors are approaching the realisation of returns on investment from ePrescribing systems in U.K. hospitals and what lessons can be learned for future developments and implementation strategies within healthcare settings. We conducted international, multi-disciplinary, round-table discussions with 21 participants from different backgrounds including policy makers, healthcare organisations, academic researchers, vendors and patient representatives. The discussions were audio-recorded, transcribed and then thematically analysed with the qualitative analysis software NVivo10. There was an over-riding concern that realising financial returns from ePrescribing systems was challenging. The underlying reasons included substantial fixed costs of care provision, the difficulties in radically changing the medicines management process and the lack of capacity within NHS hospitals to analyse and exploit the digital data being generated. Any future data strategy should take into account the need to collect and analyse local and national data (i.e. within and across hospitals), setting comparators to measure progress (i.e. baseline measurements) and clear standards guiding data management so that data are comparable across settings. A more coherent national approach to realising financial benefits from ePrescribing systems is needed as implementations progress and the range of tools to collect information will lead to exponential data growth.

PVDF and P(VDF-TrFE) nano- and micro- structures are widely used due to their potential applications in several fields, including sensors, actuators, vital sign transducers, and energy harvesters. In this study, we developed vertically aligned P(VDF-TrFE) core-shell structures using high modulus polyurethane acrylate (PUA) pillars as the support structure to maintain the structural integrity. In addition, we were able to improve the piezoelectric effect by 1.85 times from 40 ± 2 to 74 ± 2 pm/V when compared to the thin film counterpart, which contributes to the more efficient current generation under a given stress, by making an effective use ofmore » the P(VDF-TrFE) thin top layer as well as the side walls. We attribute the enhancement of piezoelectric effects to the contributions from the shell component and the strain confinement effect, which was supported by our modeling results. We envision that these organic-based P(VDF-TrFE) core-shell structures will be used widely as 3D sensors and power generators because they are optimized for current generations by utilizing all surface areas, including the side walls of core-shell structures.« less

Background A computerized physician order entry (CPOE) system with embedded clinical decision support can reduce medication errors in hospitals, but might increase the time taken to generate orders. Aims We aimed to quantify the effects of temporal (month, day of week, hour of shift) and other factors (grade of doctor, prior experience with the system, alert characteristics, and shift type) on the time taken to generate a prescription order. Setting A large university teaching hospital using a locally developed CPOE system with an extensive audit database. Design We retrospectively analyzed prescription orders from the audit database between August 2011 and July 2012. Results The geometric mean time taken to generate a prescription order within the CPOE system was 11.75 s (95% CI 11.72 to 11.78). Time to prescribe was most affected by the display of high-level (24.59 s (24.43 to 24.76); p<0.001) or previously unseen (18.87 s (18.78 to 18.96); p<0.001) alerts. Prescribers took significantly less time at weekends (11.29 s (11.23 to 11.35)) than on weekdays (11.88 s (11.84 to 11.91); p<0.001), in the first (11.25 s (11.16 to 11.34); p<0.001) and final (11.56 s (11.47 to 11.66); p<0.001) hour of their shifts, and after the first month of using the system. Conclusions The display of alerts, prescribing experience, system familiarity, and environment all affect the time taken to generate a prescription order. Our study reinforces the need for appropriate alerts to be presented to individuals at an appropriate place in the workflow, in order to improve prescribing efficiency. PMID:25074989

Northrop Grumman TR202 LOX/LH2 Deep Throttling Engine Technology Project Status

2010-01-01

NASA's Propulsion and Cryogenic Advanced Development (PCAD) project is currently developing enabling propulsion technologies in support of future lander missions. To meet lander requirements, several technical challenges need to be overcome, one of which is the ability for the descent engine(s) to operate over a deep throttle range with cryogenic propellants. To address this need, PCAD has enlisted Northrop Grumman Aerospace Systems (NGAS) in a technology development effort associated with the TR202 engine. The TR202 is a LOX/LH2 expander cycle engine driven by independent turbopump assemblies and featuring a variable area pintle injector similar to the injector used on the TR200 Apollo Lunar Module Descent Engine (LMDE). Since the Apollo missions, NGAS has continued to mature deep throttling pintle injector technology. The TR202 program has completed two series of pintle injector testing. The first series of testing used ablative thrust chambers and demonstrated igniter operation as well as stable performance at discrete points throughout the designed 10:1 throttle range. The second series was conducted with calorimeter chambers and demonstrated injector performance at discrete points throughout the throttle range as well as chamber heat flow adequate to power an expander cycle design across the throttle range. This paper provides an overview of the TR202 program, describing the different phases and key milestones. It describes how test data was correlated to the engine conceptual design. The test data obtained has created a valuable database for deep throttling cryogenic pintle technology, a technology that is readily scalable in thrust level.

Specific intestinal microbiota has been shown to induce Foxp3+ regulatory T cell development. However, it remains unclear how development of another regulatory T cell subset, Tr1 cells, is regulated in the intestine. Here, we analyzed the role of two probiotic strains of intestinal bacteria, Lactobacillus casei and Bifidobacterium breve in T cell development in the intestine. B. breve, but not L. casei, induced development of IL-10-producing Tr1 cells that express cMaf, IL-21, and Ahr in the large intestine. Intestinal CD103+ dendritic cells (DCs) mediated B. breve-induced development of IL-10-producing T cells. CD103+ DCs from Il10 −/−, Tlr2 −/−, and Myd88 −/− mice showed defective B. breve-induced Tr1 cell development. B. breve-treated CD103+ DCs failed to induce IL-10 production from co-cultured Il27ra −/− T cells. B. breve treatment of Tlr2 −/− mice did not increase IL-10-producing T cells in the colonic lamina propria. Thus, B. breve activates intestinal CD103+ DCs to produce IL-10 and IL-27 via the TLR2/MyD88 pathway thereby inducing IL-10-producing Tr1 cells in the large intestine. Oral B. breve administration ameliorated colitis in immunocompromised mice given naïve CD4+ T cells from wild-type mice, but not Il10 −/− mice. These findings demonstrate that B. breve prevents intestinal inflammation through the induction of intestinal IL-10-producing Tr1 cells. PMID:22693446

Safer Prescribing and Care for the Elderly (SPACE): feasibility of audit and feedback plus practice mail-out to patients with high-risk prescribing.

PubMed

Wallis, Katharine; Tuckey, Rebecca

2017-06-01

INTRODUCTION High-risk prescribing in general practice is common and places patients at increased risk of adverse events. AIM The Safer Prescribing and Care for the Elderly (SPACE) intervention, comprising audit and feedback plus practice mail-out to patients with high-risk prescribing, was designed to promote medicines review and support safer prescribing. This study aims to test the SPACE intervention feasibility in general practice. METHODS This feasibility study involved an Auckland Primary Health Organisation (PHO), a clinical advisory pharmacist, two purposively sampled urban general practices, and seven GPs. The acceptability and utility of the SPACE intervention were assessed by semi- structured interviews involving study participants, including 11 patients with high-risk prescribing. Interviews were audio-recorded, transcribed verbatim and analysed using a general inductive approach to identify emergent themes. RESULTS The pharmacist said the SPACE intervention facilitated communication with GPs, and provided a platform for their clinical advisory role at no extra cost to the PHO. GPs said the feedback session with the pharmacist was educational but added to time pressures. GPs selected 29 patients for the mail-out. Some GPs were concerned the mail-out might upset patients, but patients said they felt cared for. Some patients intended to take the letter to their next appointment and discuss their medicines with their GP; others said there were already many things to discuss and not enough time. Some patients were confused by the medicines information brochure. DISCUSSION The SPACE intervention is feasible in general practice. The medicines information brochure needs simplification. Further research is needed to test the effect of SPACE on high-risk prescribing.

Background In Nigeria, only medical doctors, dentists and some nurses in primary care facilities have the legal right to prescribe medicines to patients. Patients' access to prescription medicines can be seriously affected by the shortage of prescribers leading to longer waiting times in hospitals. Objective This research was carried out to investigate stakeholders' views on granting prescribing authority to pharmacists in Nigeria. Setting The study was conducted in Nigeria. Methods Qualitative, semi-structured interviews were conducted with 43 Nigerian stakeholders including policymakers, pharmacists, doctors and patient group representatives. Transcribed interviews were entered into the QSR NVivo 10 software and analysed using a thematic approach. Main outcome measure Stakeholders' perception on the granting of prescribing authority to pharmacists in Nigeria. Results Three major themes emerged from the interviews: (1) prescribing as a logical role for pharmacists, (2) pharmacist prescribing- an opportunity or a threat and (3) the potential barriers to pharmacist prescribing. Many non-medical stakeholders including pharmacists and patient group representatives supported an extended role for pharmacists in prescribing while the majority of medical doctors including those in policy making were reluctant to do so. Generally, all stakeholders perceived that pharmacist prescribing represents an opportunity to increase patients' access to medicines, reduce doctors' workload and promote the utilisation of pharmacists' skills. However, many stakeholders including pharmacists and doctors commonly identified pharmacists' inadequate skills in diagnosis, medical resistance and shortage of pharmacists as potential barriers to the introduction of pharmacist prescribing in Nigeria. Conclusion The present study showed a split of opinion between participants who were medical doctors and those who were non-doctors in their support for pharmacist prescribing. However, all

Nurses make a valuable contribution to pain services and have the potential to improve the safety and effectiveness of pain management. A recent addition to the role of the specialist pain nurse in the United Kingdom has been the introduction of prescribing rights, however there is a lack of literature about their role in prescribing pain medication. The aim of this study was to develop a profile of the experience, role and prescribing practice of these nurses. A descriptive questionnaire survey. 192 National Health Service public hospital inpatient pain services across the United Kingdom. 161 qualified nurse prescribers were invited to participate, representing 98% of known nurse prescribers contributing to inpatient pain services. The survey was completed in November 2009 by 137 nurses; a response rate of 85%. Compared with nurse prescribers in the United Kingdom in general, participants were highly qualified and experienced pain specialists. Fifty-six percent had qualified as a prescriber in the past 3 years and 22% reported that plans were underway for more nurses to undertake a nurse prescribing qualification. Although all participants worked in inpatient pain services, 35% also covered chronic pain (outpatient) services and 90% treated more than one pain type. A range of pain medications were prescribed, averaging 19.5 items per week. The role contained a strong educational component and contributed to informing organisational policy on pain management. Prescribing was said to improve nurses' ability to promote evidence-based practice but benefits were limited by legislation on prescribing controlled drugs. Findings demonstrate that pain nurses are increasingly adopting prescribing as part of their advanced nurse role. This has implications for the development needs of pain nurses in the United Kingdom and the future role development of nurses in other countries. Copyright © 2011 Elsevier Ltd. All rights reserved.

Prescribed and self-reported seasonal training of distance runners.

PubMed

Hewson, D J; Hopkins, W G

1995-12-01

A survey of 123 distance-running coaches and their best runners was undertaken to describe prescribed seasonal training and its relationship to the performance and self-reported training of the runners. The runners were 43 females and 80 males, aged 24 +/- 8 years (mean +/- S.D.), training for events from 800 m to the marathon, with seasonal best paces of 86 +/- 6% of sex- and age-group world records. The coaches and runners completed a questionnaire on typical weekly volumes of interval and strength training, and typical weekly volumes and paces of moderate and hard continuous running, for build-up, pre-competition, competition and post-competition phases of a season. Prescribed training decreased in volume and increased in intensity from the build-up through to the competition phase, and had similarities with 'long slow distance' training. Coaches of the faster runners prescribed longer build-ups, greater volumes of moderate continuous running and slower relative paces of continuous running (r = 0.19-0.36, P < 0.05), suggesting beneficial effects of not training close to competition pace. The mean training volumes and paces prescribed by the coaches were similar to those reported by the runners, but the correlations between prescribed and reported training were poor (r = 0.2-0.6). Coaches may therefore need to monitor their runners' training more closely.

Reconstruction of sound source signal by analytical passive TR in the environment with airflow

Wei, Long; Li, Min; Yang, Debin; Niu, Feng; Zeng, Wu

2017-03-01

In the acoustic design of air vehicles, the time-domain signals of noise sources on the surface of air vehicles can serve as data support to reveal the noise source generation mechanism, analyze acoustic fatigue, and take measures for noise insulation and reduction. To rapidly reconstruct the time-domain sound source signals in an environment with flow, a method combining the analytical passive time reversal mirror (AP-TR) with a shear flow correction is proposed. In this method, the negative influence of flow on sound wave propagation is suppressed by the shear flow correction, obtaining the corrected acoustic propagation time delay and path. Those corrected time delay and path together with the microphone array signals are then submitted to the AP-TR, reconstructing more accurate sound source signals in the environment with airflow. As an analytical method, AP-TR offers a supplementary way in 3D space to reconstruct the signal of sound source in the environment with airflow instead of the numerical TR. Experiments on the reconstruction of the sound source signals of a pair of loud speakers are conducted in an anechoic wind tunnel with subsonic airflow to validate the effectiveness and priorities of the proposed method. Moreover the comparison by theorem and experiment result between the AP-TR and the time-domain beamforming in reconstructing the sound source signal is also discussed.

Medication errors are globally huge in magnitude and associated with high morbidity and mortality together with high costs and legal problems. Medication errors are caused by multiple factors related to health providers, consumers and health system, but most prescribing errors are preventable. This paper is the third of 3 review articles that form the background for a series of 5 interconnected studies of prescribing patterns and medication errors in the public and private primary health care sectors of Saudi Arabia. A MEDLINE search was conducted to identify papers published in peer-reviewed journals over the previous 3 decades. The paper reviews the etiology, prevention strategies, reporting mechanisms and the myriad consequences of medication errors.

To explore the potential for community pharmacist prescribing in terms of usefulness, pharmacists' confidence, and appropriateness, in the context of asthma management. Twenty community pharmacists were recruited using convenience sampling from a group of trained practitioners who had already delivered asthma services. These pharmacists were asked to complete a scenario-based questionnaire (9 scenarios) modelled on information from real patients. Pharmacist interventions were independently reviewed and rated on their appropriateness according to the Respiratory Therapeutic Guidelines (TG) by three expert researchers. In seven of nine scenarios (78%), the most common prescribing intervention made by pharmacists agreed with TG recommendations. Although the prescribing intervention was appropriate in the majority of cases, the execution of such interventions was not in line with guidelines (i.e. dosage or frequency) in the majority of scenarios. Due to this, only 47% (76/162) of the interventions overall were considered appropriate. However, pharmacists were deemed to be often following common clinical practice for asthma prescribing. Therefore 81% (132/162) of prescribing interventions were consistent with clinical practice, which is often not guideline driven, indicating a need for specific training in prescribing according to guidelines. Pharmacists reported that they were confident in making prescribing interventions and that this would be very useful in their management of the patients in the scenarios. Community pharmacists may be able to prescribe asthma medications appropriately to help achieve good outcomes for their patients. However, further training in the guidelines for prescribing are required if pharmacists are to support asthma management in this way.

There are concerns with inappropriate prescribing of medicines among dentists especially antimicrobials. It is more concerning if this increases resistance rates. This study aimed to address this by assessing patterns of drugs prescribed for outpatients attending a hospital dental clinic in Nigeria. The findings will be used to plan future interventions, particularly around antimicrobial prescribing, where there are concerns. Medical records of patients attending the dental clinic of a leading teaching hospital in Nigeria were evaluated. Patients referred for admission, without a prescription, or prescribed medicines without a documented diagnosis were excluded. Overall, 607 prescriptions were analysed, 314 (51.7%) were for females. Periodontal and gum diseases (414; 68.1%) were the most frequent diagnoses, followed by pulpitis (49; 8.2%), and dentoalveolar abscess (43; 7.1%). A total of 1798 medicines were prescribed for all patients with a mean of 3.0 ± 0.48 medicines per prescription. Antimicrobials (1178; 65.5%) and analgesics (620; 34.5%) were the two drug classes prescribed. Ascorbic acid and vitamin B complex were prescribed for 361 (59.5%) patients. Among antimicrobials, amoxicillin (564; 95.1%) either alone or combined with clavulanic acid was the most frequently prescribed, followed by metronidazole (561; 94.6%). Brand name prescribing was also appreciably higher than WHO recommendations. Polypharmacy, brand name prescriptions, and the frequent prescription of antimicrobials were common practices at the dental clinic of this teaching hospital in Nigeria. We suggest a review of the current standard treatment guidelines in Nigeria to guide dentists on current knowledge- and evidence-based treatment of common oral diseases.

Opioid misuse is a public health crisis that stems in part from overprescribing by health-care providers. Surgical residents are commonly responsible for prescribing opioids at patient discharge, and residency program directors (PDs) are charged with their residents' education. Because each hospital and state has different opioid prescribing policies, we sought to assess PDs' knowledge about local controlled substance prescribing polices. A survey was emailed to surgery PDs that included questions regarding residency characteristics and knowledge of state regulations. A total of 247 PDs were emailed with 110 (44.5%) completed responses. One hundred and four (94.5%) allow residents to prescribe outpatient opioids; one was unsure. Sixty-three (57.3%) respondents correctly answered if their state required opioid prescribing education for full licensure. Twenty-two (20.0%) were unsure if their state required opioid prescribing education for licensure. Sixty-four (58.2%) respondents answered correctly if a prescription monitor programs use is required in their state. Twenty-nine (26.4%) were unsure if a state prescription monitor programs existed. Seventy-six (69.1%) PDs answered correctly about their state's requirement for an additional registration to prescribe controlled substances; 10 (9.1%) did not know if this was required. Twenty-nine (27.9%) programs require residents to obtain individual drug enforcement agency registration; 5 (4.8%) were unsure if this was required. Most programs allow residents to prescribe outpatient opioids. However, this survey demonstrated a considerable gap in PDs' knowledge about controlled substance regulations. Because they oversee surgical residents' education, PDs should be versed about their local policies in this matter. Copyright © 2018 Elsevier Inc. All rights reserved.

Pilot evaluation of a method to assess prescribers' information processing of medication alerts.

Prescribers commonly receive alerts during medication ordering. Prescribers work in a complex, time-pressured environment; to enhance the effectiveness of safety alerts, the effort needed to cognitively process these alerts should be minimized. Methods to evaluate the extent to which computerized alerts support prescribers' information processing are lacking. To develop a methodological protocol to assess the extent to which alerts support prescribers' information processing at-a-glance; specifically, the incorporation of information into their working memory. We hypothesized that the method would be feasible and that we would be able to detect a significant difference in prescribers' information processing with a revised alert display that incorporates warning design guidelines compared to the original alert display. A counterbalanced, within-subject study was conducted with 20 prescribers in a human-computer interaction laboratory. We tested a single alert that was displayed in two different ways. Prescribers were informed that an alert would appear for 10s. After the alert was shown, a white screen was displayed, and prescribers were asked to verbally describe what they saw; indicate how many total warnings; and describe anything else they remembered about the alert. We measured information processing via the accuracy of prescribers' free recall and their ability to identify that three warning messages were present. Two analysts independently evaluated participants' responses against a comprehensive catalog of alert elements and then discussed discrepancies until reaching consensus. This feasibility study demonstrated that the method seemed to be effective for evaluating prescribers' information processing of medication alert displays. With this method, we were able to detect significant differences in prescribers' recall of alert information. The proportion of total data elements that prescribers were able to accurately recall was significantly greater for the

As the majority of prescribing in hospital is undertaken by intern doctors, the aims of this systematic review were to compile the evidence of the qualitative literature on the views and experiences of intern doctors and to examine the role of the pharmacist in assisting in prescribing by interns. A systematic review of the qualitative literature was done according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. The findings were synthesized using thematic analysis. Seven publications were included. Factors influencing prescribing behaviour were related to the environment; collaboration in medical teams; hierarchical structures; and patient and individual factors. This review confirmed that interns’ prescribing behaviour is influenced by multiple factors, and further highlighted the need for an educational intervention that supports the intern completing the prescribing task in a complex environment, and not just addresses the presumed knowledge gap(s).

A single-chip CMOS-based (complementary-metal-oxide-semiconductorbased) transmit/receive (T/R) module is being developed for L-band radar systems. Previous T/R module implementations required multiple chips employing different technologies (GaAs, Si, and others) combined with off-chip transmission lines and discrete components including circulators. The new design eliminates the bulky circulator, significantly reducing the size and mass of the T/R module. Compared to multi-chip designs, the single-chip CMOS can be implemented with lower cost. These innovations enable cost-effective realization of advanced phased array and synthetic aperture radar systems that require integration of thousands of T/R modules. The circulator is a ferromagnetic device that directs the flow of the RF (radio frequency) power during transmission and reception. During transmission, the circulator delivers the transmitted power from the amplifier to the antenna, while preventing it from damaging the sensitive receiver circuitry. During reception, the circulator directs the energy from the antenna to the low-noise amplifier (LNA) while isolating the output of the power amplifier (PA). In principle, a circulator could be replaced by series transistors acting as electronic switches. However, in practice, the integration of conventional series transistors into a T/R chip introduces significant losses and noise. The prototype single-chip T/R module contains integrated transistor switches, but not connected in series; instead, they are connected in a shunt configuration with resonant circuits (see figure). The shunt/resonant circuit topology not only reduces the losses associated with conventional semiconductor switches but also provides beneficial transformation of impedances for the PA and the LNA. It provides full singlepole/ double-throw switching for the antenna, isolating the LNA from the transmitted signal and isolating the PA from the received signal. During reception, the voltage on

This research investigated the reported optometric prescribing criteria of Israeli optometrists. An online questionnaire based on previous studies was distributed via email and social networking sites to optometrists in Israel. The questionnaire surveyed the level of refractive error at which respondents would prescribe for different types of refractive error at various ages with and without symptoms. 124 responses were obtained, yielding a response rate of approximately 12-22%, 92% of whom had trained in Israel. For all refractive errors, the presence of symptoms strongly influenced prescribing criteria. For example, for 10-20 year old patients the degree of hyperopia for which 50% of practitioners would prescribe is +0.75 D in the presence of symptoms but twice this value (+1.50 D) in the absence of symptoms. As might be expected, optometrists prescribed at lower degrees of hyperopia for older compared with younger patients. There was a trend for more experienced practitioners to be less likely to prescribe for lower degrees of myopia and presbyopia. Practitioner gender, country of training, the type of practice environment, and financial incentives were not strongly related to prescribing criteria. The prescribing criteria found in this study are broadly comparable with those in previous studies and with published prescribing guidelines. Subtle indications suggest that optometrists may become more conservative in their prescribing criteria with experience. Copyright © 2015 Spanish General Council of Optometry.

The positive intrinsic negative (PIN) diode switch which is designed to protect the receiver from burnout or damage on transmission and channel the echo signal to the receiver on reception is outlined. The receiver must be protected firmly. A schematic diagram of a transformer rectifier (TR-ATR) switch for the Urbana Radar is shown. The T/R switch consists of a half wavelength coaxial cavity with tuning condenser and PIN diodes. Two UM4300 PIN diodes were mounted between the inner and outer conductor. The dc biasing voltage required for the PIN diodes is supplied by a control circuit. On transmission, the PIN diodes are forward biased to about 0.5 amperes. On reception, about 10 volts reverse voltage is applied to the diodes, which produces an initial reverse current to speed the recovery time. The T/R switch characteristics are estimated and the result of testing at different peak transmitter powers from 410 kW to 1500 kW is shown.

There is controversy regarding the optimal dialysate sodium concentration for hemodialysis patients. Dialysate sodium concentrations of 134 to 138 mEq/L may decrease interdialytic weight gain and improve hypertension control, whereas a higher dialysate sodium concentration may offer protection to patients with low serum sodium concentrations and hypotension. We conducted a quality improvement project to explore the hypothesis that prescribed and delivered dialysate sodium concentrations may differ significantly. Cross-sectional quality improvement project. 333 hemodialysis treatments in 4 facilities operated by Dialysis Clinic, Inc. Measure dialysate sodium to assess the relationships of prescribed and measured dialysate sodium concentrations. Magnitude of differences between prescribed and measured dialysate sodium concentrations. Dialysate sodium measured pre- and late dialysis. The least square mean of the difference between prescribed minus measured dialysate sodium concentration was -2.48 (95% CI, -2.87 to -2.10) mEq/L. Clinics with a greater number of different dialysate sodium prescriptions (clinic 1, n=8; clinic 2, n=7) and that mixed dialysate concentrates on site had greater differences between prescribed and measured dialysate sodium concentrations. Overall, 57% of measured dialysate sodium concentrations were within ±2 mEq/L of the prescribed dialysate sodium concentration. Differences were greater at higher prescribed dialysate sodium concentrations. We only studied 4 facilities and dialysate delivery machines from 2 manufacturers. Because clinics using premixed dialysate used the same type of machine, we were unable to independently assess the impact of these factors. Pressures in dialysate delivery loops were not measured. There were significant differences between prescribed and measured dialysate sodium concentrations. This may have beneficial or deleterious effects on clinical outcomes, as well as confound results from studies assessing the

Prescribing errors are an important cause of patient safety incidents and are frequently caused by junior doctors. This might be because the prescribing competence of final-year medical students is poor as a result of inadequate clinical pharmacology and therapeutic (CPT) education. We reviewed the literature to investigate which prescribing competencies medical students should have acquired in order to prescribe safely and effectively, and whether these have been attained by the time they graduate. PubMed, EMBASE and ERIC databases were searched from the earliest dates up to and including January 2017, using the terms 'prescribing', 'competence' and 'medical students' in combination. Articles describing or evaluating essential prescribing competencies of final-year medical students were included. Twenty-five articles describing, and 47 articles evaluating, the prescribing competencies of final-year students were included. Although there seems to be some agreement, we found no clear consensus among CPT teachers on which prescribing competencies medical students should have when they graduate. Studies showed that students had a general lack of preparedness, self-confidence, knowledge and skills, specifically regarding general and antimicrobial prescribing and pharmacovigilance. However, the results should be interpreted with caution, given the heterogeneity and methodological weaknesses of the included studies. There is considerable evidence that final-year students have insufficient competencies to prescribe safely and effectively, although there is a need for a greater consensus among CPT teachers on the required competencies. Changes in undergraduate CPT education are urgently required in order to improve the prescribing of future doctors. © 2018 VU University Medical Centre.

"Nudges" that influence decision making through subtle cognitive mechanisms have been shown to be highly effective in a wide range of applications, but there have been few experiments to improve clinical practice. To investigate the use of a behavioral "nudge" based on the principle of public commitment in encouraging the judicious use of antibiotics for acute respiratory infections (ARIs). Randomized clinical trial in 5 outpatient primary care clinics. A total of 954 adults had ARI visits during the study timeframe: 449 patients were treated by clinicians randomized to the posted commitment letter (335 in the baseline period, 114 in the intervention period); 505 patients were treated by clinicians randomized to standard practice control (384 baseline, 121 intervention). The intervention consisted of displaying poster-sized commitment letters in examination rooms for 12 weeks. These letters, featuring clinician photographs and signatures, stated their commitment to avoid inappropriate antibiotic prescribing for ARIs. Antibiotic prescribing rates for antibiotic-inappropriate ARI diagnoses in baseline and intervention periods, adjusted for patient age, sex, and insurance status. Baseline rates were 43.5% and 42.8% for control and poster, respectively. During the intervention period, inappropriate prescribing rates increased to 52.7% for controls but decreased to 33.7% in the posted commitment letter condition. Controlling for baseline prescribing rates, we found that the posted commitment letter resulted in a 19.7 absolute percentage reduction in inappropriate antibiotic prescribing rate relative to control (P = .02). There was no evidence of diagnostic coding shift, and rates of appropriate antibiotic prescriptions did not diminish over time. Displaying poster-sized commitment letters in examination rooms decreased inappropriate antibiotic prescribing for ARIs. The effect of this simple, low-cost intervention is comparable in magnitude to costlier, more

To assess nurse practitioners' interactions with pharmaceutical industry promotional activities and their perception of information reliability and self-reported prescribing behaviors. Self-administered online survey. A nationally randomized sample of nurse practitioner prescribers was surveyed. Eligibility criteria included current clinical practice and licensure to prescribe medications in their state of practice. A total of 263 responses were analyzed. Almost all respondents (96%) reported regular contact with pharmaceutical sales representatives, and most (71%) reported receiving information on new drugs directly from pharmaceutical sales representatives some or most of the time. A large portion (66%) dispensed drug samples regularly to their patients, and 73% believed that samples were somewhat or very helpful in learning about new drugs. Eighty-one percent of respondents thought that it was ethically acceptable to give out samples to anyone, and 90% believed that it was acceptable to attend lunch and dinner events sponsored by the pharmaceutical industry. Almost half (48%) stated that they were more likely to prescribe a drug that was highlighted during a lunch or dinner event. Most respondents stated that it was ethically acceptable for speakers to be paid by industry. Nurse practitioner prescribers had extensive contact with pharmaceutical industry promotional activities such as pharmaceutical representative contact, receipt of drug samples, and regular attendance at industry-sponsored meal events and continuing education programs. They reported that industry interface with nurse practitioner prescribers in the form of sponsored meals, education events, and paid speakers was ethically acceptable.

Antimicrobial resistance is a worldwide threat to public health. Acute respiratory tract infections are the main reason for antibiotic prescribing in the Spanish paediatric population. The aim of the study was to describe the frequency of antibiotic prescription and their pattern of use in acute respiratory tract infections diagnosed in children in Primary Care in Aragón (Spain). A study was conducted over a 1-year period on children between 0 and 14 years-old, recording all episodes of acute otitis, acute pharyngotonsillitis, non-specific upper respiratory infection, and acute bronchitis. The proportion of episodes within each diagnosis receiving an antibiotic prescription was calculated, and the prescribing pattern was determined. Half (50%) of the children in Aragón were diagnosed with a respiratory tract infection during the study period. Non-specific upper respiratory infection was the most frequent diagnosis. An antibiotic was prescribed in 75% of pharyngotonsillitis episodes, 72% of otitis, 27% of bronchitis, and 16% of non-specific upper respiratory infections. Broad spectrum antibiotics, mainly amoxicillin and amoxicillin-clavulanic, were predominantly prescribed. Antibiotic prescribing in respiratory tract infections in children was generally high, and the choice of antibiotics was probably inappropriate in a high percentage of cases. Therefore an improvement in antibiotic prescribing in children appears to be needed. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

Abstract The aim of this study was to identify and examine the differences in opinions held by health care professionals and the general public concerning the right to administer and prescribe medication which has been awarded to nurses and midwives in Poland. The study was conducted from December 1, 2014 to July 1, 2015, in randomly selected primary health care clinics, among 2227 individuals, including 849 subjects representing medical personnel of primary health care and 1378 patients receiving primary care services. The study used 2 versions of a questionnaire. The relationships were examined with χ2 test for independence and Kruskal–Wallis test. Health professionals do not believe the new rights awarded to nurses and midwives will reduce the waiting time for medical consultations (P < 0.001). Nurses’ qualifications for the new tasks were most highly rated by patients, whereas the least favorable opinion was expressed by doctors (P < 0.001). To introduce nurse prescribing it is necessary to develop a suitable strategy enabling implementation of the government's initiative and facilitating the process of taking up the new task by nurses.

To Prescribe or Not to Prescribe? Consumer Access to Life-Enhancing Products

2017-01-01

Abstract With rapid biotechnological advances in specialty drugs and direct-to-consumer advertising, consumers are under tremendous pressure to look, perform, feel, and live better. This is often accomplished through the use of life-enhancing products, sometimes referred to as performance-enhancing products, which can be accessed only through a gatekeeper, such as a physician. Integrating consumer and medical research, this article investigates how physicians make trade-offs between objective medical and nonmedical factors to determine consumers’ access to life-enhancing products by examining US pediatric endocrinologists’ prescription decisions for growth hormone (GH) for healthy but short children. The results of a conjoint study indicate that consumer medical criteria have less impact on a physician’s decision to prescribe GH if the consumer requests a prescription or the physician believes in the intangible product benefits, and more impact when the product is more expensive. A physician’s length of experience increases the impact of consumer medical criteria and decreases the influence of a consumer’s preference for a prescription on the decision to prescribe. Overall, this research shows that not all consumers have equal access to life-enhancing products; their access depends on a complex combination of medical and nonmedical factors related to the consumer, product, and the physician.

Choline is an essential nutrient for phospholipids and acetylcholine biosynthesis in normal development of fetus. In the present study, we investigated the functional characteristics of choline transport system and inhibitory effect of cationic drugs on choline transport in rat conditionally immortalized syncytiotrophoblast cell line (TR-TBT). Choline transport was weakly Na(+) dependent and significantly influenced by extracellular pH and by membrane depolarization. The transport process of choline is saturable with Michaelis-Menten constants (K(m)) of 68microM and 130microM in TR-TBT 18d-1 and TR-TBT 18d-2 respectively. Choline uptake in the cells was inhibited by unlabeled choline and hemicholinium-3 as well as various organic cations including guanidine, amiloride and acetylcholine. However, the prototypical organic cation tetraethylammonium and cimetidine showed very little inhibitory effect of choline uptake in TR-TBT cells. RT-PCR revealed that choline transporter-like protein 1 (CTL1) and organic cation transporter 2 (OCT2) are expressed in TR-TBT cells. The transport properties of choline in TR-TBT cells were similar or identical to that of CTL1 but not OCT2. CTL1 was also detected in human placenta. In addition, several cationic drugs such as diphenhydramine and verapamil competitively inhibited choline uptake in TR-TBT 18d-1 with K(i) of 115microM and 55microM, respectively. Our results suggest that choline transport system, which has intermediate affinity and weakly Na(+) dependent, in TR-TBT seems to occur through a CTL1 and this system may have relevance with the uptake of pharmacologically important organic cation drugs.

P(VDF/TrFE) morphologies and crystalline lamellae orientations dependence on substrates characterized by scanning probe microscopy

Ultra-thin films of the polyvinylidene fluoride and trifluoroethylene (P(VDF/TrFE)) copolymer were elaborated on various different substrates by the spin coating method. The purpose of this paper is to study the P(VDF/TrFE) morphologies and crystalline lamellae orientation dependence on substrates. We chose the potassium chloride (KCl), Sodium Chloride (NaCl) and Potassium Bromide (KBr) with the [110] direction and the highly ordered pyrolytic graphite (HOPG) substrates because they present different crystallographic structures. The atomic force microscopy is used for imaging P(VDF/TrFE) morphologies with nanometer resolution and determining the surface roughness. The analysis of the AFM topography images revealed that the P(VDF/TrFE) film has, almost, the same texture on KCl, NaCl or on KBr substrates and their crystalline lamellae had grown in two preferred orientations. Unlike the HOPG substrate, their crystalline lamellae were entangled, randomly oriented and positioned adjacent to each other. The growth texture of the P(VDF/TrFE) copolymer showed experimentally a strong dependence on substrate types. Since the P(VDF/TrFE) is ferroelectric, piezoelectric and pyroelectric, this finding may lead to potential applications.

Background: Pharmacists in Canada have been prescribing since 2007. This review aims to explore the volume, array and nature of research activity on Canadian pharmacist prescribing and to identify gaps in the existing literature. Methods: We conducted a scoping review to examine the literature on prescribing by pharmacists in Canada according to methodological trends, research areas and key findings. We searched for peer-reviewed research articles and abstracts in the Ovid MEDLINE, Ovid EMBASE and International Pharmaceutical Abstracts databases without any date limitations. A standardized form was used to extract information. Results: We identified 156 articles; of these, 26 articles and 12 abstracts met inclusion criteria. One-half of the research studies (20) used quantitative methods, including surveys, trials and experimental designs; 11 studies used qualitative methods and 7 used other methods. Research on pharmacist prescribing demonstrated an improvement in patient outcomes (13 studies), varied stakeholder perceptions (10 studies) and factors that influence this practice change (11 studies). Pharmacist prescribing was adopted when pharmacists practised patient-centred care. Stakeholders held contrasting perceptions of pharmacist prescribing. Discussion: Canadian research has demonstrated the benefit of pharmacist prescribing on patient outcomes, which is not present in the international literature. Future research may consider a meta-analysis addressing the impact on patient health. Gaps in research include comparisons between provinces, effects on physicians’ services, overall patient safety and access to health care systems and economic implications for society. Conclusion: A growing body of research on pharmacist prescribing has captured the early impact of prescribing on patient outcomes, perceptions of practice and practice change. Opportunities exist for pan-Canadian research that examines the system impact. PMID:26600824

Prescribing family criticism as a paradoxical intervention.

PubMed

Bergman, J S

1983-12-01

Two case studies are presented in which parental criticism of children was prescribed in two fused families, who in part were fused because of the mutual and intense criticism between the parents and children. In both cases, prescribing the criticism resulted in blocking the parental criticism, thus forcing the family members to interact in new and different ways. Blocking the criticism permitted the individuals and the family to evolve to the next developmental stages in the family life cycle. Discussion is detailed as to why the prescription of family criticism led to shifts in the family system.

Evoking prescribed spike times in stochastic neurons

Single cell stimulation in vivo is a powerful tool to investigate the properties of single neurons and their functionality in neural networks. We present a method to determine a cell-specific stimulus that reliably evokes a prescribed spike train with high temporal precision of action potentials. We test the performance of this stimulus in simulations for two different stochastic neuron models. For a broad range of parameters and a neuron firing with intermediate firing rates (20-40 Hz) the reliability in evoking the prescribed spike train is close to its theoretical maximum that is mainly determined by the level of intrinsic noise.

Prescribing glucose requires complex calculations because glucose is present in parenteral and enteral nutrition and drug vehicles, making it error prone and contributing to the burden of prescribing errors. Evaluation of the impact of a computerized physician order entry (CPOE) system with clinical decision support (CDS) for glucose control in neonatal intensive care patients (NICU) focusing on hypo- and hyperglycemic episodes and prescribing time efficiency. An interrupted time-series design to examine the effect of CPOE on hypo- and hyperglycemias and a crossover simulation study to examine the influence of CPOE on prescribing time efficiency. NICU patients at risk for glucose imbalance hospitalized at the University Medical Center Utrecht during 2001-2007 were selected. The risks of hypo- and hyperglycemias were expressed as incidences per 100 patient days in consecutive 3-month intervals during 3 years before and after CPOE implementation. To assess prescribing time efficiency, time needed to calculate glucose intake with and without CPOE was measured. No significant difference was found between pre- and post-CPOE mean incidences of hypo- and hyperglycemias per 100 hospital days of neonates at risk in every 3-month period (hypoglycemias, 4.0 [95% confidence interval, 3.2-4.8] pre-CPOE and 3.1 [2.7-3.5] post-CPOE, P = .88; hyperglycemias, 6.0 [4.3-7.7] pre-CPOE and 5.0 [3.7-6.3] post-CPOE, P = .75). CPOE led to a significant time reduction of 16% (1.3 [0.3-2.3] minutes) for simple and 60% (8.6 [5.1-12.1] minutes) for complex calculations. CPOE including a special CDS tool preserved accuracy for calculation and control of glucose intake and increased prescribing time efficiency.

There are contrasting opinions on the use of prescribed burning management in European grasslands. On the one hand, prescribed burning can be effectively used for the management of open landscapes, controlling dominant species, reducing accumulated litter or decreasing wildfire risk. On the other hand burning can have a detrimental impact on grassland biodiversity by supporting competitor grasses and by threatening several rare and endangered species, especially arthropods. We studied the effects of prescribed burning in alkaline grasslands of high conservation interest. Our aim was to test whether dormant-season prescribed burning can be an alternative conservation measure in these grasslands. We selected six sites in East-Hungary: in three sites, a prescribed fire was applied in November 2011, while three sites remained unburnt. We studied the effects of burning on soil characteristics, plant biomass and on the composition of vegetation and arthropod assemblages (isopods, spiders, ground beetles and rove beetles). Soil pH, organic matter, potassium and phosphorous did not change, but soluble salt content increased significantly in the burnt sites. Prescribed burning had several positive effects from the nature conservation viewpoint. Shannon diversity and the number of flowering shoots were higher, and the cover of the dominant grass Festuca pseudovina was lower in the burnt sites. Graminoid biomass was lower, while total, green and forb biomass were higher in the burnt plots compared to the control. The key finding of our study was that prescribed burning did not decrease the abundance and diversity of arthropod taxa. Species-level analyses showed that out of the most abundant invertebrate species, 10 were not affected, 1 was negatively and 1 was positively affected by burning. Moreover, our results suggest that prescribed burning leaving unburnt patches can be a viable management tool in open landscapes, because it supports plant diversity and does not threaten

OBJECTIVE The optimal approach to auditing outpatient antimicrobial prescribing has not been established. We assessed how different types of electronic data-including prescriptions, patient-visits, and International Classification of Disease, Tenth Revision (ICD-10) codes-could inform automated antimicrobial audits. DESIGN Outpatient visits during 2016 were retrospectively reviewed, including chart abstraction, if an antimicrobial was prescribed (cohort 1) or if the visit was associated with an infection-related ICD-10 code (cohort 2). Findings from cohorts 1 and 2 were compared. SETTING Primary care clinics and the emergency department (ED) at the Iowa City Veterans Affairs Medical Center. RESULTS In cohort 1, we reviewed 2,353 antimicrobial prescriptions across 52 providers. ICD-10 codes had limited sensitivity and positive predictive value (PPV) for validated cases of cystitis and pneumonia (sensitivity, 65.8%, 56.3%, respectively; PPV, 74.4%, 52.5%, respectively). The volume-adjusted antimicrobial prescribing rate was 13.6 per 100 ED visits and 7.5 per 100 primary care visits. In cohort 2, antimicrobials were not indicated in 474 of 851 visits (55.7%). The antimicrobial overtreatment rate was 48.8% for the ED and 59.7% for primary care. At the level of the individual prescriber, there was a positive correlation between a provider's volume-adjusted antimicrobial prescribing rate and the individualized rates of overtreatment in both the ED (r=0.72; P<.01) and the primary care setting (r=0.82; P=0.03). CONCLUSIONS In this single-center study, ICD-10 codes had limited sensitivity and PPV for 2 infections that typically require antimicrobials. Electronically extracted data on a provider's rate of volume-adjusted antimicrobial prescribing correlated with the frequency at which unnecessary antimicrobials were prescribed, but this may have been driven by outlier prescribers.

Excessive opioid prescribing is common after curative-intent surgery, but little is known about what factors influence prescribing behaviors among surgeons. To identify targets for intervention, we performed a qualitative study of opioid prescribing after curative-intent surgery using the Theoretical Domains Framework, a well-established implementation science method for identifying factors influencing healthcare provider behavior. Prior to data collection, we constructed a semi-structured interview guide to explore decision making for opioid prescribing. We then conducted interviews with surgical oncology providers at a single comprehensive cancer center. Interviews were recorded, transcribed verbatim, then independently coded by two investigators using the Theoretical Domains Framework to identify theoretical domains relevant to opioid prescribing. Relevant domains were then linked to behavior models to select targeted interventions likely to improve opioid prescribing. Twenty-one subjects were interviewed from November 2016 to May 2017, including attending surgeons, resident surgeons, physician assistants, and nurses. Five theoretical domains emerged as relevant to opioid prescribing: environmental context and resources; social influences; beliefs about consequences; social/professional role and identity; and goals. Using these domains, three interventions were identified as likely to change opioid prescribing behavior: (1) enablement (deploy nurses during preoperative visits to counsel patients on opioid use); (2) environmental restructuring (provide on-screen prompts with normative data on the quantity of opioid prescribed); and (3) education (provide prescribing guidelines). Key determinants of opioid prescribing behavior after curative-intent surgery include environmental and social factors. Interventions targeting these factors are likely to improve opioid prescribing in surgical oncology.

Aims Prescribing errors are an important cause of patient safety incidents and are frequently caused by junior doctors. This might be because the prescribing competence of final‐year medical students is poor as a result of inadequate clinical pharmacology and therapeutic (CPT) education. We reviewed the literature to investigate which prescribing competencies medical students should have acquired in order to prescribe safely and effectively, and whether these have been attained by the time they graduate. Methods PubMed, EMBASE and ERIC databases were searched from the earliest dates up to and including January 2017, using the terms ‘prescribing’, ‘competence’ and ‘medical students’ in combination. Articles describing or evaluating essential prescribing competencies of final‐year medical students were included. Results Twenty‐five articles describing, and 47 articles evaluating, the prescribing competencies of final‐year students were included. Although there seems to be some agreement, we found no clear consensus among CPT teachers on which prescribing competencies medical students should have when they graduate. Studies showed that students had a general lack of preparedness, self‐confidence, knowledge and skills, specifically regarding general and antimicrobial prescribing and pharmacovigilance. However, the results should be interpreted with caution, given the heterogeneity and methodological weaknesses of the included studies. Conclusions There is considerable evidence that final‐year students have insufficient competencies to prescribe safely and effectively, although there is a need for a greater consensus among CPT teachers on the required competencies. Changes in undergraduate CPT education are urgently required in order to improve the prescribing of future doctors. PMID:29315721

PVDF and P(VDF-TrFE) nano- and micro- structures have been widely used due to their potential applications in several fields, including sensors, actuators, vital sign transducers, and energy harvesters. In this study, we developed vertically aligned P(VDF-TrFE) core-shell structures using high modulus polyurethane acrylate (PUA) pillars as the support structure to maintain the structural integrity. In addition, we were able to improve the piezoelectric effect by 1.85 times from 40 ± 2 to 74 ± 2 pm/V when compared to the thin film counterpart, which contributes to the more efficient current generation under a given stress, by making an effective use of the P(VDF-TrFE) thin top layer as well as the side walls. We attribute the enhancement of piezoelectric effects to the contributions from the shell component and the strain confinement effect, which was supported by our modeling results. We envision that these organic-based P(VDF-TrFE) core-shell structures will be used widely as 3D sensors and power generators because they are optimized for current generations by utilizing all surface areas, including the side walls of core-shell structures.

Appropriate antibiotic prescribing is an essential strategy to reduce the spread of antibiotic resistance. US prescribing practices have not been thoroughly characterized. We analyzed outpatient antibiotic prescribing data to identify where appropriate antibiotic prescribing interventions could have the most impact. Oral antibiotic prescriptions dispensed during 2011 were extracted from the IMS Health Xponent database. The number of prescriptions and census denominators were used to calculate prescribing rates. Prescription totals were calculated for each provider specialty. Regression modeling was used to examine the association between socioeconomic and population health factors and prescribing rates. Healthcare providers prescribed 262.5 million courses of antibiotics in 2011(842 prescriptions per 1000 persons). Penicillins and macrolides were the most common antibiotic categories prescribed. The most commonly prescribed individual antibiotic agent was azithromycin. Family practitioners prescribed the most antibiotic courses (24%). The prescribing rate was higher in the South census region (931 prescriptions per 1000 persons) than in the West (647 prescriptions per 1000 persons; P < .001); this pattern was observed among all age groups, including children ≤ 2 and persons ≥ 65 years of age. Counties with a high proportion of obese persons, infants and children ≤ 2 years of age, prescribers per capita, and females were more likely to be high prescribing by multivariable analysis (adjusted odds ratio, >1.0). Efforts to characterize antibiotic prescribing practices should focus on the South census region and family practitioners. Further understanding of the factors leading to high prescribing among key target populations will inform appropriate prescribing interventions.

Vagge, Aldo; Nelson, Leonard B

2017-09-01

The present review article is an update on the current evidence about compliance to the prescribed occlusion treatment for amblyopia. In particular, the authors focus on the predictors and causes of noncompliance and possible interventions to increase it. Compliance with prescribed occlusion treatment is often challenging. Reported rates of compliance range widely from 49% to 87%. Objective monitoring of occlusion has opened up new research opportunities and allow the design of effective therapeutic regimens. Also, predictors and causes of noncompliance have been investigated and their knowledge may help the clinician to improved compliance with prescribed occlusion treatment for amblyopia. Although many of the studies assessing the effectiveness of interventions to increase compliance to patching treatment for amblyopia have many limitations, evidences support that use of educational supports, parents, and patient understanding on the importance of patching and written information should be considered to increase compliance with patching.

The audit of drug prescribing pattern in under-five children is essential in identifying the various types of non-rational prescribing such as polypharmacy and irrational use of antimicrobials. The primary objective of this study was to determine the drug prescribing pattern for children aged below five years attending the paediatric outpatient clinic of a tertiary hospital in Ado-Ekiti, South-West Nigeria. A cross-sectional study was carried out using the medical records of patients who attended the paediatric clinic of the hospital between April 1 and October 30, 2013. The medical records of patients aged below five years were selected monthly for the period of the study using a regular interval ratio. Drug use indicators were assessed using the WHO guidelines on investigation of drug use in health care facilities. There were 293(55.7%) prescriptions collected from male patients and 233(44.3% from female patients with a total of 1369 prescribed drugs (2.6 ± 1.1 drugs per prescription). A total of three hundred and seventy-four (71.1%) patients had at least one antibiotic prescribed with antibiotics accounting for 28.2% of all drugs prescribed, while 13.5% of all encounters had an injection prescribed. Prescribing by generic name was done in 68.9 ± 26.5% of all prescribed medications, and 60.4% of all prescribed medications were from the latest version of the Nigerian Essential Drug List. Three hundred and twelve children (59.3%) had at least one anti-malarial drug prescribed while analgesics drugs accounted for 6.1% of all prescriptions. This study showed that over-prescription of antibiotics, significant use of injections and prescribing by generic name are real issues among Nigerian paediatric prescribers.

Impact of smoke from prescribed burning: Is it a public health concern?

Given the increase in wildfire intensity and frequency worldwide, prescribed burning is becoming a more common and widespread practice. Prescribed burning is a fire management tool used to reduce fuel loads for wildfire suppression purposes and occurs on an annual basis in many parts of the world. Smoke from prescribed burning can have a substantial impact on air quality and the environment. Prescribed burning is a significant source of fine particulate matter (PM2.5 aerodynamic diameter<2.5µm) and these particulates are found to be consistently elevated during smoke events. Due to their fine nature PM2.5 are particularly harmful to human health. Here we discuss the impact of prescribed burning on air quality particularly focussing on PM2.5. We have summarised available case studies from Australia including a recent study we conducted in regional Victoria, Australia during the prescribed burning season in 2013. The studies reported very high short-term (hourly) concentrations of PM2.5 during prescribed burning. Given the increase in PM2.5 concentrations during smoke events, there is a need to understand the influence of prescribed burning smoke exposure on human health. This is important especially since adverse health impacts have been observed during wildfire events when PM2.5 concentrations were similar to those observed during prescribed burning events. Robust research is required to quantify and determine health impacts from prescribed burning smoke exposure and derive evidence based interventions for managing the risk. Given the increase in PM2.5 concentrations during PB smoke events and its impact on the local air quality, the need to understand the influence of PB smoke exposure on human health is important. This knowledge will be important to inform policy and practice of the integrated, consistent, and adaptive approach to the appropriate planning and implementation of public health strategies during PB events. This will also have important implications

Ensuring appropriate prescribing is an important challenge for the health service, and the need for research that takes account of the reasons behind individual general practitioners' (GPs) prescribing decisions has been highlighted. To explore differences among GPs in their decisions to prescribe new drugs. Qualitative approach, using in-depth semistructured interviews. Northern and Yorkshire Health Authority Region. Participants were identified from a random sample of 520 GPs in a quantitative study of patterns of uptake of eight recently introduced drugs. Purposeful sampling ensured inclusion of GPs prescribing any of the eight drugs and working in a range of practice settings. Fifty-six GPs were interviewed, using a topic guide. Interviews were recorded on audiotape. Transcribed text was methodically coded and data were analysed by constantly comparing emerging themes. Both low and high prescribers shared a view of themselves as conservative in their prescribing behaviour. Low prescribers appeared to conform more strongly to group norms and identified a consensus among practice partners in prescribing and cost-consciousness. Conformism to group norms was represented by a commitment to practice formularies. High prescribers more often expressed themselves to be indifferent to drug costs and a shared practice ethos. A shift in the attitudes of some GPs is required before cost-effectiveness is routinely incorporated in drug prescribing. The promotion of rational prescribing is likely to be more successful if efforts are focused on GPs' appreciation of cost issues and attitudes towards shared decision-making and responsibility.

Opioid analgesics are effective and appropriate therapy for many types of acute pain. Epidemiologic evidence supports a direct relationship between increased opioid prescribing and increases in opioid use disorders and overdoses. To tailor our residency curriculum, we designed and fielded an unannounced standardized patient (USP) case involving a patient with acute back pain who is requesting Vicodin (5/325 mg). We describe residents' case management and examine whether their management decisions, including opioid prescribing, were related to their core clinical skills. Results are based on 50 (USP) visits with residents in 2 urban primary care clinics. Highly trained USPs portrayed a patient with acute lower back pain who was taking leftover Vicodin with effective pain relief but was running out. We describe how residents managed this case, using both USP report and chart review data, and compare summary clinical skills scores between those who prescribed Vicodin and those who did not. Of the 50 residents, 18 prescribed Vicodin (10-60 pills). Among those who did not prescribe (32/50), most (50%) prescribed ibuprofen. Eighty-three percent of the prescribers and 72% of nonprescribers ordered physical therapy (nonsignificant). Of the 18 prescribers, 13 documented checking the prescription monitoring database. Prescribers had significantly better communication scores than nonprescribers (relationship development: 80% vs. 58% well done, P = .029; patient education: 59% vs. 31% well done, P = .018). Assessment summary scores were also higher (60% vs. 46%) but not significantly (P = .060). Patient satisfaction and activation scores were higher in the prescribers than nonprescribers (71% vs. 39%, P = .004 and 48% vs. 26%, P = .034, respectively). Most Vicodin prescribers did not follow prescribing guidelines, and they demonstrated better communication and assessment skills than the nonprescribers. Results suggest the need to guide residents in using a systematic approach

Clinically irrelevant but psychologically important factors such as patients' expectations for antibiotics encourage overprescribing. We aimed to (a) provide missing causal evidence of this effect, (b) identify whether the expectations distort the perceived probability of a bacterial infection either in a pre- or postdecisional distortions pathway, and (c) detect possible moderators of this effect. Family physicians expressed their willingness to prescribe antibiotics (Experiment 1, n₁ = 305) or their decision to prescribe (Experiment 2, n₂ = 131) and assessed the probability of a bacterial infection in hypothetical patients with infections either with low or high expectations for antibiotics. Response order of prescribing/probability was manipulated in Experiment 1. Overall, the expectations for antibiotics increased intention to prescribe (Experiment 1, F(1, 301) = 25.32, p < .001, η p ² = .08, regardless of the response order; Experiment 2, odds ratio [OR] = 2.31, and OR = 0.75, Vignettes 1 and 2, respectively). Expectations for antibiotics did not change the perceived probability of a bacterial infection (Experiment 1, F(1, 301) = 1.86, p = .173, η p ² = .01, regardless of the response order; Experiment 2, d = -0.03, and d = +0.25, Vignettes 1 and 2, respectively). Physicians' experience was positively associated with prescribing, but it did not moderate the expectations effect on prescribing. Patients' and their parents' expectations increase antibiotics prescribing, but their effect is localized-it does not leak into the perceived probability of a bacterial infection. Interventions reducing the overprescribing of antibiotics should target also psychological factors. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Background Medication error is an important contributor to patient morbidity and mortality and is associated with inadequate patient safety measures. However, prescribing-safety tools specifically designed for use in general practice are lacking. Aim To identify and update a set of prescribing-safety indicators for assessing the safety of prescribing in general practice, and to estimate the risk of harm to patients associated with each indicator. Design and setting RAND/UCLA consensus development of indicators in UK general practice. Method Prescribing indicators were identified from a systematic review and previous consensus exercise. The RAND Appropriateness Method was used to further identify and develop the indicators with an electronic-Delphi method used to rate the risk associated with them. Twelve GPs from all the countries of the UK participated in the RAND exercise, with 11 GPs rating risk using the electronic-Delphi approach. Results Fifty-six prescribing-safety indicators were considered appropriate for inclusion (overall panel median rating of 7–9, with agreement). These indicators cover hazardous prescribing across a range of therapeutic indications, hazardous drug–drug combinations and inadequate laboratory test monitoring. Twenty-three (41%) of these indicators were considered high risk or extreme risk by 80% or more of the participants. Conclusion This study identified a set of 56 indicators that were considered, by a panel of GPs, to be appropriate for assessing the safety of GP prescribing. Twenty-three of these indicators were considered to be associated with high or extreme risk to patients and should be the focus of efforts to improve patient safety. PMID:24686882

OBJECTIVES: The objective was to explore whether prescribing variation is associated with duration of antidepressant use during the acute phase of treatment. Improving quality of care and increasing the extent to which treatment is patient-centered and customized are interrelated goals. Prescribing variation may be considered a marker of customization, and could be associated with better antidepressant treatment adherence. METHODS: A cross-sectional secondary data analysis examining the association between providers' antidepressant prescribing variation and patient continuity of antidepressant treatment. The data source was two states' Medicaid claims for dual-eligible Medicaid/Medicare patients. The sample included 383 patients with new episodes of antidepressant treatment, representing 70 providers with at least four patients in the sample. We tested two alternate measures of prescribing concentration: 1) share of prescriber's initial antidepressant prescribing accounted for by the two most common regimens, and 2) Herfindahl index. The HEDIS performance measure of effective acute-phase treatment (at least 84 out of 114 days with antidepressant) was the dependent variable. KEY FINDINGS: In multivariate analyses, the concentration measure based on the top two regimens was significant and inversely related to duration adequacy (p <.05). The Herfindahl index measure showed a trend towards a similar inverse relationship (p<.10). CONCLUSIONS: The findings provide some support for the hypothesized relationship between prescribing variation and adequate antidepressant treatment duration during the acute phase of treatment. Future work with more detailed, clinical longitudinal data could extend this inquiry to better understand the causal mechanisms using a more direct measure of customized care.

The goal of this study was to investigate patterns of ambulatory antibiotic use and to identify factors associated with broad-spectrum antibiotic prescribing for pediatric urinary tract infections (UTIs). We examined antibiotics prescribed for UTIs for children aged younger than 18 years from 1998 to 2007 using the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey. Amoxicillin-clavulanate, quinolones, macrolides, and second- and third-generation cephalosporins were classified as broad-spectrum antibiotics. We evaluated trends in broad-spectrum antibiotic prescribing patterns and performed multivariable logistic regression to identify factors associated with broad-spectrum antibiotic use. Antibiotics were prescribed for 70% of pediatric UTI visits. Trimethoprim-sulfamethoxazole was the most commonly prescribed antibiotic (49% of visits). Broad-spectrum antibiotics were prescribed one third of the time. There was no increase in overall use of broad-spectrum antibiotics (P = .67); however, third-generation cephalosporin use doubled from 12% to 25% (P = .02). Children younger than 2 years old (odds ratio: 6.4 [95% confidence interval: 2.2-18.7, compared with children 13-17 years old]), females (odds ratio: 3.6 [95% confidence interval: 1.6-8.5]), and temperature ≥ 100.4°F (odds ratio: 2.9 [95% confidence interval: 1.0-8.6]) were independent predictors of broad-spectrum antibiotic prescribing. Race, physician specialty, region, and insurance status were not associated with antibiotic selection. Ambulatory care physicians commonly prescribe broad-spectrum antibiotics for the treatment of pediatric UTIs, especially for febrile infants in whom complicated infections are more likely. The doubling in use of third-generation cephalosporins suggests that opportunities exist to promote more judicious antibiotic prescribing because most pediatric UTIs are susceptible to narrower alternatives.

BACKGROUND: Good clinical practice in primary care includes periodic review of repeat prescriptions. Markers of prescriptions that may need review have been described, but manually checking all repeat prescriptions against the markers would be impractical. AIM: To investigate the feasibility of computerising the application of repeat prescribing quality checks to electronic patient records in United Kingdom (UK) primary care. DESIGN OF STUDY: Software performance test against benchmark manual analysis of cross-sectional convenience sample of prescribing documentation. SETTING: Three general practices in Greater Manchester, in the north west of England, during a 4-month period in 2001. METHOD: A machine-readable drug information resource, based on the British National Formulary (BNF) as the 'gold standard' for valid drug indications, was installed in three practices. Software raised alerts for each repeat prescribed item where the electronic patient record contained no valid indication for the medication. Alerts raised by the software in two practices were analysed manually. Clinical reaction to the software was assessed by semi-structured interviews in three practices. RESULTS: There was no valid indication in the electronic medical records for 14.8% of repeat prescribed items. Sixty-two per cent of all alerts generated were incorrect. Forty-three per cent of all incorrect alerts were as a result of errors in the drug information resource, 44% to locally idiosyncratic clinical coding, 8% to the use of the BNF without adaptation as a gold standard, and 5% to the inability of the system to infer diagnoses that, although unrecorded, would be 'obvious' to a clinical reading the record. The interviewed clinicians supported the goals of the software. CONCLUSION: Using electronic records for secondary decision support purposes will benefit from (and may require) both more consistent electronic clinical data collection across multiple sites, and reconciling clinicians

Resistance to the use of prescribed fire is strong among many private land managers despite the advantages it offers for maintaining fire-adapted ecosystems. Even managers who are aware of the benefits of using prescribed fire as a management tool avoid using it, citing potential liability as a major reason for their aversion. Recognizing the importance of prescribed fire for ecosystem management and the constraints current statutory schemes impose on its use, several states in the United States have undertaken prescribed burn statutory reform. The stated purpose of these statutory reforms, often called "right to burn" or "prescribed burning" acts, is to encourage prescribed burning for resource protection, public safety, and land management. Our research assessed the consequences of prescribed burn statutory reform by identifying legal incentives and impediments to prescribed fire application for ecosystem restoration and management, as well as fuel reduction. Specifically, we explored the relationship between prescribed burning laws and decisions made by land managers by exploiting a geographic-based natural experiment to compare landowner-prescribed fire use in contiguous counties with different regulations and legal liability standards. Controlling for potentially confounding variables, we found that private landowners in counties with gross negligence liability standards burn significantly more hectares than those in counties with simple negligence standards (F6,72 = 4.16, P = 0.046). There was no difference in hectares burned on private land between counties with additional statutorily mandated regulatory requirements and those requiring only a permit to complete a prescribed burn (F6,72 = 1.42, P = 0.24) or between counties with burn ban exemptions for certified prescribed burn managers and those with no exemptions during burn bans (F6,72 = 1.39, P = 0.24).

International Non-proprietary Name (INN) prescribing is the use of the name of the active ingredient(s) instead of the brand name for prescribing. In Belgium, INN prescribing began in 2005 and a major policy change occurred in 2012. The aim was to explore the opinions of Dutch-speaking general practitioners (GPs) and pharmacists. An electronic questionnaire with 39 five-point Likert scale statements and one open question was administered in 2013. Multivariate analysis was performed with multiple linear regression on a sum score for benefit statements and for drawback statements. Answers to the open question were qualitatively analysed. We received 745 valid responses with a representable sample for both subgroups. Participants perceived the motives to introduce INN prescribing as purely economic (to reduce pharmaceutical expenditures for the government and the patient). Participants accepted the concept of INN prescribing, but 88% stressed the importance of guaranteed treatment continuity, especially in older, chronic patients, to prevent patient confusion, medication non-adherence and erroneous drug use. In conclusion, the current way in which INN prescribing is applied in Belgium leads to many concerns among primary health professionals about patient confusion and medication adherence. Slightly adapting the current concept of INN prescribing to these concerns can turn INN prescribing into one of the major policies in Belgium to reduce pharmaceutical expenditures and to stimulate rational drug prescribing. © 2014 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

Prescribed fires are a common nature conservation practice. They are executed by several parties with limited coordination among them, and little consideration for wildfire occurrences and habitat requirements of fire-dependent species. Here, we gathered data on prescribed fires and wildfires in Sweden during 2011-2015 to (i) evaluate the importance and spatial extent of prescribed fires compared to wildfires and (ii) illustrate how a database can be used as a management tool for prescribed fires. We found that on average only 0.006% (prescribed 65%, wildfires 35%) of the Swedish forest burns per year, with 58% of the prescribed fires occurring on clearcuts. Also, both wildfires and prescribed fires seem to be important for the survival of fire-dependent species. A national fire database would simplify coordination and make planning and evaluation of prescribed fires more efficient. We propose an adaptive management strategy to improve the outcome of prescribed fires.

OBJECTIVE: To analyze the prevalence and types of prescribing and dispensing errors occurring with high-alert medications and to propose preventive measures to avoid errors with these medications. INTRODUCTION: The prevalence of adverse events in health care has increased, and medication errors are probably the most common cause of these events. Pediatric patients are known to be a high-risk group and are an important target in medication error prevention. METHODS: Observers collected data on prescribing and dispensing errors occurring with high-alert medications for pediatric inpatients in a university hospital. In addition to classifying the types of error that occurred, we identified cases of concomitant prescribing and dispensing errors. RESULTS: One or more prescribing errors, totaling 1,632 errors, were found in 632 (89.6%) of the 705 high-alert medications that were prescribed and dispensed. We also identified at least one dispensing error in each high-alert medication dispensed, totaling 1,707 errors. Among these dispensing errors, 723 (42.4%) content errors occurred concomitantly with the prescribing errors. A subset of dispensing errors may have occurred because of poor prescription quality. The observed concomitancy should be examined carefully because improvements in the prescribing process could potentially prevent these problems. CONCLUSION: The system of drug prescribing and dispensing at the hospital investigated in this study should be improved by incorporating the best practices of medication safety and preventing medication errors. High-alert medications may be used as triggers for improving the safety of the drug-utilization system. PMID:22012039

2018-01-05

Prescription opioid overdoses have increased dramatically in recent years, with the highest rates among Medicaid enrollees. High-risk prescribing includes practices associated with overdoses and a range of additional opioid-related problems. To identify individual- and county-level factors associated with high-risk prescribing among Medicaid enrollees receiving opioids. In a four-states, cross-sectional claims data study, Medicaid enrollees 18-64 years old with a new opioid analgesic treatment episode 2007-2009 were identified. Multivariate regression analyses were conducted to identify factors associated with high-risk prescribing, defined as high-dose opioid prescribing (morphine equivalent daily dose ≥100 mg for >6 days), opioid overlap, opioid-benzodiazepine overlap. High-risk prescribing occurred in 39.4% of episodes. Older age, rural county of residence, white race, and major depression diagnosis were associated with higher rates of all types of high-risk prescribing. Individuals with prior opioid, alcohol, and hypnotic/sedative use disorder diagnoses had lower odds of high-dose opioid prescribing but higher odds of opioid overlap and opioid-benzodiazepine overlap than individuals without such disorders. High-dose opioid prescribing in Massachusetts was less common than in California, Illinois, and New York, whereas the rate of benzodiazepine overlap in Massachusetts was more common than in other states. Conclusions/Importance: High-risk prescribing was common and associated with several important demographic, clinical, and community factors. Findings can be used to inform targeted interventions designed to reduce such prescribing, and given state variation observed, further research is needed to better understand the effects of state policies on high-risk prescribing.

The impact of the Canterbury earthquakes on prescribing for mental health.

2015-08-01

The aim of this study is to evaluate the impact of the Canterbury earthquakes on the mental health of the local population by examining prescribing patterns of psychotropic medication. Dispensing data from community pharmacies for antidepressants, antipsychotics, anxiolytics and sedatives/hypnotics are routinely recorded in a national database. The close relationship between prescribing and dispensing provides the opportunity to assess prescribing trends for Canterbury compared to national data and therefore examines the longitudinal impact of the earthquakes on prescribing patterns. Short-term increases in the use of anxiolytics and sedatives/hypnotics were observed after the most devastating February 2011 earthquake, but this effect was not sustained. There were no observable effects of the earthquakes on antidepressant or antipsychotic dispensing. Short-term increases in dispensing were only observed for the classes of anxiolytics and sedatives/hypnotics. No sustained changes in dispensing occurred. These findings suggest that long-term detrimental effects on the mental health of the Canterbury population were either not present or have not resulted in increased prescribing of psychotropic medication. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Prescribed Velocity Gradients for Highly Viscous SPH Fluids with Vorticity Diffusion.

PubMed

Peer, Andreas; Teschner, Matthias

2017-12-01

Working with prescribed velocity gradients is a promising approach to efficiently and robustly simulate highly viscous SPH fluids. Such approaches allow to explicitly and independently process shear rate, spin, and expansion rate. This can be used to, e.g., avoid interferences between pressure and viscosity solvers. Another interesting aspect is the possibility to explicitly process the vorticity, e.g., to preserve the vorticity. In this context, this paper proposes a novel variant of the prescribed-gradient idea that handles vorticity in a physically motivated way. In contrast to a less appropriate vorticity preservation that has been used in a previous approach, vorticity is diffused. The paper illustrates the utility of the vorticity diffusion. Therefore, comparisons of the proposed vorticity diffusion with vorticity preservation and additionally with vorticity damping are presented. The paper further discusses the relation between prescribed velocity gradients and prescribed velocity Laplacians which improves the intuition behind the prescribed-gradient method for highly viscous SPH fluids. Finally, the paper discusses the relation of the proposed method to a physically correct implicit viscosity formulation.

Children with asthma require multiple medications, and cost may be a barrier to care. The purpose of this study was to determine how often physicians ask about cost when prescribing new asthma medication and to identify factors influencing queries. We surveyed pediatricians and family physicians and asked whether they asked about cost when prescribing new asthma medication and if cost was a barrier to prescribing. One third of physicians (35%) reported that concern for cost to the family was a barrier to prescribing. Half reported not asking their patients about drug costs. Pediatricians were less likely to ask about cost (odds ratio [OR] = 0.43; 95% confidence interval [CI] = 0.20–0.92) when compared with family physicians. For every 10% increase in the number of privately insured patients, a physician was less likely to ask about cost (OR = 0.83; 95% CI = 0.74–0.94). Communication about medication costs should be included in childhood asthma management. PMID:19164133

New photometric follow-up observations of transitting 'hot Jupiters' TrES-3b and Qatar-1b are presented. Weighted mean values of the solutions of light curves in R-filter for both planetary systems are reported and compared with the previous results. The transit light curves were analysed using the WINFITTER code. The physical properties of the planets were estimated. The planet radii are found to be Rp = 1.381 ± 0.033RJ for TrES-3b and Rp = 1.142 ± 0.025RJ for Qatar-1b. Transit times and their uncertainties were also determined and a new linear ephemeris was computed for both systems. Analysis of transit times showed that a significant signal could not be determined for TrES-3b, while weak evidence was found for Qatar-1b, which might be tested using more precise future transit times.

Hans Georg Trüper (1936–2016) and His Contributions to Halophile Research

Prof. Hans Georg Trüper, one of the most important scientists in the field of halophile research, passed away on 9 March 2016 at the age of 79. I here present a brief obituary with special emphasis on Prof. Trüper’s contributions to our understanding of the halophilic prokaryotes and their adaptations to life in hypersaline environments. He has pioneered the study of the halophilic anoxygenic phototrophic sulfur bacteria of the Ectothiorhodospira—Halorhodospira group. Some of the species he and his group isolated from hypersaline and haloalkaline environments have become model organisms for the study of the mechanisms of haloadaptation: the functions of three major organic compounds – glycine betaine, ectoine, and trehalose – known to serve as “compatible solutes” in halophilic members of the Bacteria domain, were discovered during studies of these anoxygenic phototrophs. Prof. Trüper’s studies of hypersaline alkaline environments in Egypt also led to the isolation of the first known extremely halophilic archaeon (Natronomonas pharaonis). The guest editors dedicate this special volume of Life to the memory of Prof. Hans Georg Trüper. PMID:27187481

Comparing personality disorder models: cross-method assessment of the FFM and DSM-IV-TR.

PubMed

Samuel, Douglas B; Widiger, Thomas W

2010-12-01

The current edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; American Psychiatric Association, 2000) defines personality disorders as categorical entities that are distinct from each other and from normal personality traits. However, many scientists now believe that personality disorders are best conceptualized using a dimensional model of traits that span normal and abnormal personality, such as the Five-Factor Model (FFM). However, if the FFM or any dimensional model is to be considered as a credible alternative to the current model, it must first demonstrate an increment in the validity of the assessment offered within a clinical setting. Thus, the current study extended previous research by comparing the convergent and discriminant validity of the current DSM-IV-TR model to the FFM across four assessment methodologies. Eighty-eight individuals receiving ongoing psychotherapy were assessed for the FFM and the DSM-IV-TR personality disorders using self-report, informant report, structured interview, and therapist ratings. The results indicated that the FFM had an appreciable advantage over the DSM-IV-TR in terms of discriminant validity and, at the domain level, convergent validity. Implications of the findings and directions for future research are discussed.

Objective: Irrational pharmacotherapy is a widespread health care problem, and knowing the prescription practices of physicians at an institutional level can present solutions. This study aimed to investigate whether physicians’ prescribing patterns showed differences at the level of the health care institution. Materials and Methods: Photocopies of 3201 prescriptions written at primary health care centers (PHCs), public hospitals, private hospitals, and university hospitals (UHs) were collected from 10 provinces in Turkey. The prescriptions were evaluated according to prescribing indicators, and the details of drug utilization were compared for different health care institutions. Results: The average number of medicines per prescription was 2.83, and the highest average was noted in PHCs (2.96). The average cost per prescription was US $51.57, and the highest average cost was found in UHs (US $166.10). The most frequently prescribed drug group was different among health care institutions. With the exception of UHs, the “cold-cough medicines” were the most frequently prescribed medicines at all of the institutions. Thirty-nine percent of the prescriptions included antibiotics. Conclusion: Despite the similarities between the distributions of diagnoses on prescriptions by health care institutions, the contents of the prescriptions showed differences. The high levels of prescriptions for “cold-cough medicines,” whose use is widely debated, and the widespread tendency of physicians to prescribe antibiotics suggest that there is a growing need for disseminating the principles of rational pharmacotherapy. Furthermore, institutional differences must be considered when conducting rational pharmacotherapy programs. PMID:25610260

Reducing antibiotic prescribing in Australian general practice: time for a national strategy.

In Australia, the antibiotic resistance crisis may be partly alleviated by reducing antibiotic use in general practice, which has relatively high prescribing rates - antibiotics are mostly prescribed for acute respiratory infections, for which they provide only minor benefits. Current surveillance is inadequate for monitoring community antibiotic resistance rates, prescribing rates by indication, and serious complications of acute respiratory infections (which antibiotic use earlier in the infection may have averted), making target setting difficult. Categories of interventions that may support general practitioners to reduce prescribing antibiotics are: regulatory (eg, changing the default to "no repeats" in electronic prescribing, changing the packaging of antibiotics to facilitate tailored amounts of antibiotics for the right indication and restricting access to prescribing selected antibiotics to conserve them), externally administered (eg, academic detailing and audit and feedback on total antibiotic use for individual GPs), interventions that GPs can individually implement (eg, delayed prescribing, shared decision making, public declarations in the practice about conserving antibiotics, and self-administered audit), supporting GPs' access to near-patient diagnostic testing, and public awareness campaigns. Many unanswered clinical research questions remain, including research into optimal implementation methods. Reducing antibiotic use in Australian general practice will require a range of approaches (with various intervention categories), a sustained effort over many years and a commitment of appropriate resources and support.

This study was carried out to: (1) explore the views of pharmacists in Nigeria on the extension of prescribing authority to them and determine their willingness to be prescribers and (2) identify the potential facilitators and barriers to introducing pharmacist prescribing in Nigeria. An online cross-sectional survey was conducted from August to October 2014 among 775 pharmacists recruited from the Facebook group of the Pharmaceutical Society of Nigeria using a simple random technique. The questionnaire used for the survey was developed based on the review of the literature and previous qualitative studies conducted in Nigeria. The instrument was evaluated for content validity by two external pharmacy practice researchers and the reliability of items assessed using internal consistency tests. Data obtained from the survey were entered into SPSS v.22, and descriptive statistics were generated. Relationships between variables were evaluated using the chi-square test, and P < 0.05 was considered statistically significant. The response rate was 40.6% (315/775). Three hundred and six (97.1%) respondents agreed that pharmacists should be given prescribing authority. Of these 306, 295 (96.4%) were willing to be prescribers, and just over half of them (148/295; 50.2%) would prefer to prescribe in collaboration with medical doctors. Of those willing to be prescribers, 285 (96.6%) reported that they would need additional training. The most perceived areas of training needed were in the principles of differential diagnosis (81.4%), pathophysiology of diseases (74.0%) and interpretation of laboratory results (68.1%). Respondents identified increasing patients' access to care (308/315; 97.8%) and better utilisation of pharmacists' skills (307/315; 97.5%) as the most likely facilitators to pharmacist prescribing in Nigeria. On the other hand, resistance from the medical doctors (299/315; 94.9%) and pharmacists' inadequate skills in diagnosis (255/315; 81.0%) were perceived as

A pilot qualitative study to explore stakeholder opinions regarding prescribing quality indicators

2012-01-01

Background Information on prescribing quality of diabetes care is required by health care providers, insurance companies, policy makers, and the public. Knowledge regarding the opinions and preferences of all involved parties regarding prescribing quality information is important for effective use of prescribing quality indicators. Methods Between June and December 2009 we conducted semi structured interviews with 16 key-informants representing eight different organizations in the Netherlands involved in healthcare quality measurement and improvement. The interview guide included topics on participants’ opinions and preferences regarding existing types of prescribing quality indicators in relation to their aim of using quality information. Content analysis methods were used to process the resulting transcripts following the framework of predetermined themes. Results Findings from this qualitative study of stakeholder preferences showed that indicators focusing on undertreatment are found important by all participants. Furthermore, health care providers and policy makers valued prescribing safety indicators, insurance companies prioritized indicators focusing on prescribing costs, and patients’ organization representatives valued indicators focusing on interpersonal side of prescribing. Representatives of all stakeholders preferred positive formulation of the indicators to motivate health care providers to participate in health improvement programs. A composite score was found to be most useful by all participants as a starting point of prescribing quality assessment. Lack of information on reasons for deviating from guidelines recommendations appeared to be the most important barrier for using prescribing quality indicators. According to the health care providers, there are many legitimate reasons for not prescribing the recommended treatment and these reasons are not always taken into account by external evaluators. The latter may cause mistrust of health care

2015-01-01

Objectives Evaluate health plan interventions targeting physician chronic opioid therapy (COT) prescribing. Methods In 2006, Group Health’s (GH) integrated group practice (IGP) initiated diverse interventions targeting COT prescriber norms and practices. In 2010, the IGP implemented a COT guideline, including a mandated online course for physicians managing COT. These interventions were not implemented in GH’s network practices. We compared trends in GH-IGP and network practices for 2006–12 in the percent of patients receiving COT and their opioid dose. We compared physician beliefs before versus after the mandated course and pre- to post-course changes in COT dosing for IGP physicians who took the course. Results From 2006 to 2012, mean (SE) daily opioid dose among IGP COT patients (intervention setting) declined from 74.1 (1.9) mg. morphine equivalent dose (MED) to 48.3 (1.0) mg. MED. Dose changes among GH network COT patients (control setting) were modest—88.2 (5.0) mg. MED in 2006 to 75.7 (2.3) mg. MED in 2012. Among physicians taking the mandated course in 2011, we observed pre- to post-course changes toward more conservative opioid prescribing beliefs. However, COT dosing trends did not change pre- to post-course. Discussion Following initiatives implemented to alter physician prescribing practices and norms, mean opioid dose prescribed to COT patients declined more in intervention than control practices. Physicians reported more conservative beliefs regarding opioid prescribing immediately after completing an online course in 2011, but the course was not associated with additional reductions in mean daily opioid dose prescribed by physicians completing the course.

Introduction: European countries need to learn from each other to address unsustainable increases in pharmaceutical expenditures. Objective: To assess the influence of the many supply and demand-side initiatives introduced across Europe to enhance prescribing efficiency in ambulatory care. As a result provide future guidance to countries. Methods: Cross national retrospective observational study of utilization (DDDs – defined daily doses) and expenditure (Euros and local currency) of proton pump inhibitors (PPIs) and statins among 19 European countries and regions principally from 2001 to 2007. Demand-side measures categorized under the “4Es” – education engineering, economics, and enforcement. Results: Instigating supply side initiatives to lower the price of generics combined with demand-side measures to enhance their prescribing is important to maximize prescribing efficiency. Just addressing one component will limit potential efficiency gains. The influence of demand-side reforms appears additive, with multiple initiatives typically having a greater influence on increasing prescribing efficiency than single measures apart from potentially “enforcement.” There are also appreciable differences in expenditure (€/1000 inhabitants/year) between countries. Countries that have not introduced multiple demand side measures to counteract commercial pressures to enhance the prescribing of generics have seen considerably higher expenditures than those that have instigated a range of measures. Conclusions: There are considerable opportunities for European countries to enhance their prescribing efficiency, with countries already learning from each other. The 4E methodology allows European countries to concisely capture the range of current demand-side measures and plan for the future knowing that initiatives can be additive to further enhance their prescribing efficiency.

Many woodland understories are managed with prescribed fire. While prescribed burns intended to manipulate understory vegetation and fuels usually do not cause excessive tree mortality, sublethal canopy damage may occur and can affect tree vigor and reproductive output. We monitored Quercus garryana trees in western Washington, USA with multiple...

A potential consequence of using prescribed fire is heat-related injury to timber trees. Scars formed following fire injuries are often associated with extensive decay in hardwoods. The ability to predict scarring caused by prescribed fire is important when multiple management goals are incorporated on a single forest site.

Due to the high rates of inappropriate antibiotic prescribing for presumed urinary tract infections (UTIs) in nursing home (NH) residents, we sought to examine the antibiotic prescribing pathway and the extent to which it agrees with the Loeb criteria; findings can suggest strategies for antibiotic stewardship. Chart review of 260 randomly-selected cases from 247 NH residents treated with an antibiotic for a presumed UTI in 31 NHs in North Carolina. We examined the prescribing pathway from presenting illness, to the prescribing event, illness work-up and subsequent clinical events including emergency department use, hospitalization, and death. Analyses described the decision-making processes and outcomes and compared decisions made with Loeb criteria for initiation of antibiotics. Of 260 cases, 60% had documented signs/symptoms of the presenting illness and 15% met the Loeb criteria. Acute mental status change was the most commonly documented sign/symptom (24%). NH providers (81%) were the most common prescribers and ciprofloxacin (32%) was the most commonly prescribed antibiotic. Fourteen percent of presumed UTI cases included a white blood cell count, 71% included a urinalysis, and 72% had a urine culture. Seventy-five percent of cultures grew at least one organism with ≥100,000 colony-forming units/milliliter and 12% grew multi-drug resistant organisms; 28% of antibiotics were prescribed for more than 7 days, and 7% of cases had a subsequent death, emergency department visit, or hospitalization within 7 days. Non-specific signs/symptoms appeared to influence prescribing more often than urinary tract-specific signs/symptoms. Prescribers rarely stopped antibiotics, and a minority prescribed for overly long periods. Providers may need additional support to guide the decision-making process to reduce antibiotic overuse and antibiotic resistance. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Shrub-Steppe Early Succession Following Juniper Cutting and Prescribed Fire

Pinus- Juniperus L. (Piñon-juniper) woodlands of the western United States have expanded in area nearly 10-fold since the late 1800's. Juniperus occidentalis ssp. occidentalis Hook. (western juniper) dominance in sagebrush steppe has several negative consequences, including reductions in herbaceous production and diversity, decreased wildlife habitat, and higher erosion and runoff potentials. Prescribed fire and mechanical tree removal are the main methods used to control J. occidentalis and restore sagebrush steppe. However, mature woodlands become difficult to prescribe burn because of the lack of understory fuels. We evaluated partial cutting of the woodlands (cutting 25-50% of the trees) to increase surface fuels, followed by prescribed fire treatments in late successional J. occidentalis woodlands of southwest Idaho to assess understory recovery. The study was conducted in two different plant associations and evaluated what percentage of the woodland required preparatory cutting to eliminate remaining J. occidentalis by prescribed fire, determined the impacts of fire to understory species, and examined early post-fire successional dynamics. The study demonstrated that late successional J. occidentalis woodlands can be burned after pre-cutting only a portion of the trees. Early succession in the cut-and-burn treatments were dominated by native annual and perennial forbs, in part due to high mortality of perennial bunchgrasses. By the third year after fire the number of establishing perennial grass seedlings indicated that both associations would achieve full herbaceous recovery. Cutting-prescribed fire combinations are an effective means for controlling encroaching late successional J. occidentalis and restoring herbaceous plant communities. However, land managers should recognize that there are potential problems associated with cutting-prescribed fire applications when invasive weeds are present.

A majority of doctor-patient meetings result in the patient getting a prescription. This underlines the need for a high-quality prescription process. While studies have been made on single therapeutic drug groups, a complete study of the physicians' general thought process that comprises the prescription of all drugs still remains to be made. To identify variations in ways of understanding drug prescribing among GPs. A descriptive qualitative study was conducted with 20 Swedish physicians. Informants were recruited purposively and their understandings about prescribing were studied in semi-structured interviews. Data were analysed using a phenomenographic approach. Five categories were identified as follows: (A) GP prescribed safe, reliable and well-documented drugs for obvious complaints; (B) GP sought to convince the patient of the most effective drug treatment; (C) GP chose the best drug treatment taking into consideration the patient's entire life situation; (D) GP used clinical judgement and close follow-up to minimize unnecessary drug prescribing and (E) GP prescribed drugs which are cheap for society and environmentally friendly. The categories are interrelated, but have different foci: the biomedical, the patient and the society. Each GP had more than one view but none included all five. The findings also indicate that complexity increases when a drug is prescribed for primary or secondary prevention. GPs understand prescribing differently despite similar external circumstances. The most significant factor to influence prescribing behaviour was the physician's patient relation approach. GPs may need to reflect on difficulties they face while prescribing to enhance their understandings.

Hints of Period Change for OGLE-TR-113b

We present six new transits of the hot Jupiter OGLE-TR-113b observed with MagIC on the Magellan Telescopes between January 2007 and May 2009. We update the system parameters and revise the planetary radius, where the error is dominated by stellar radius uncertainties. The new transit midtimes reveal no transit timing variations from a constant ephemeris over two years, which places an upper limit of 1-2 Earth masses on any perturber in a 1:2 or 2:1 mean-motion resonance with OGLE-TR-113b. Combining the new transit epochs with five epochs published between 2002 and 2006, we find hints that the orbital period of the planet may not be constant, with the best fit indicating the period is decreasing by 60±15 milliseconds per year. If real, this change in period could result from either a long-period (more than 8 years) timing variation due to an external perturber, or more intriguingly from the orbital decay of the planet. The detection of a changing period is still tentative and must be checked with additional observations. If a period decay is confirmed, OGLE-TR-113b will be the first planet observed to be falling onto its star. This would enable direct tests of tidal stability and dynamical models of close-in planets and place observational constraints on the value of stellar tidal energy dissipation factors.

The association between industry payments to physicians and prescribing rates of the brand-name medications that are being promoted is controversial. In the United States, industry payment data and Medicare prescribing records recently became publicly available. To study the association between physicians' receipt of industry-sponsored meals, which account for roughly 80% of the total number of industry payments, and rates of prescribing the promoted drug to Medicare beneficiaries. Cross-sectional analysis of industry payment data from the federal Open Payments Program for August 1 through December 31, 2013, and prescribing data for individual physicians from Medicare Part D, for all of 2013. Participants were physicians who wrote Medicare prescriptions in any of 4 drug classes: statins, cardioselective β-blockers, angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers (ACE inhibitors and ARBs), and selective serotonin and serotonin-norepinephrine reuptake inhibitors (SSRIs and SNRIs). We identified physicians who received industry-sponsored meals promoting the most-prescribed brand-name drug in each class (rosuvastatin, nebivolol, olmesartan, and desvenlafaxine, respectively). Data analysis was performed from August 20, 2015, to December 15, 2015. Receipt of an industry-sponsored meal promoting the drug of interest. Prescribing rates of promoted drugs compared with alternatives in the same class, after adjustment for physician prescribing volume, demographic characteristics, specialty, and practice setting. A total of 279 669 physicians received 63 524 payments associated with the 4 target drugs. Ninety-five percent of payments were meals, with a mean value of less than $20. Rosuvastatin represented 8.8% (SD, 9.9%) of statin prescriptions; nebivolol represented 3.3% (7.4%) of cardioselective β-blocker prescriptions; olmesartan represented 1.6% (3.9%) of ACE inhibitor and ARB prescriptions; and desvenlafaxine represented 0.6% (2.6%) of

Correctional facilities are a major provider of mental health care throughout the United States. In spite of the numerous benefits of providing care in this setting, clinicians are sometimes concerned about entering into correctional care because of uncertainty in prescribing practices. This article provides an introduction to prescription drug use, abuse, and diversion in the correctional setting, including systems issues in prescribing, commonly abused prescription medications, motivation for and detection of prescription drug abuse, and the use of laboratory monitoring. By understanding the personal and systemic factors that affect prescribing habits, the clinician can develop a more rewarding correctional practice and improve care for inmates with mental illness.

Primary Tr1 cells from metastatic melanoma eliminate tumor-promoting macrophages through granzyme B- and perforin-dependent mechanisms.

In malignant melanoma, tumor-associated macrophages play multiple roles in promoting tumor growth, such as inducing the transformation of melanocytes under ultraviolet irradiation, increasing angiogenesis in melanomas, and suppressing antitumor immunity. Because granzyme B- and perforin-expressing Tr1 cells could specifically eliminate antigen-presenting cells of myeloid origin, we examined whether Tr1 cells in melanoma could eliminate tumor-promoting macrophages and how the interaction between Tr1 cells and macrophages could affect the growth of melanoma cells. Tr1 cells were characterized by high interleukin 10 secretion and low Foxp3 expression and were enriched in the CD4 + CD49b + LAG-3 + T-cell fraction. Macrophages derived from peripheral blood monocytes in the presence of modified melanoma-conditioned media demonstrated tumor-promoting capacity, exemplified by improving the proliferation of cocultured A375 malignant melanoma cells. But when primary Tr1 cells were present in the macrophage-A375 coculture, the growth of A375 cells was abrogated. The conventional CD25 + Treg cells, however, were unable to inhibit macrophage-mediated increase in tumor cell growth. Further analyses showed that Tr1 cells did not directly eliminate A375 cells, but mediated the killing of tumor-promoting macrophages through the secretion of granzyme B and perforin. The tumor-infiltrating interleukin 10 + Foxp3 - CD4 + T cells expressed very low levels of granzyme B and perforin, possibly suggested the downregulation of Tr1 cytotoxic capacity in melanoma tumors. Together, these data demonstrated an antitumor function of Tr1 cells through the elimination of tumor-promoting macrophages, which was not shared by conventional Tregs.

Fusarium wilt (also known as Panama disease) is one of the most destructive banana diseases, and greatly hampers the global production of bananas. Consequently, it has been very detrimental to the Chinese banana industry. An infected plant is one of the major causes of the spread of Fusarium wilt to nearby regions. It is essential to develop an efficient and environmentally sustainable disease control method to restrict the spread of Fusarium wilt. We isolated Trichoderma spp from the rhizosphere soil, roots, and pseudostems of banana plants that showed Fusarium wilt symptoms in the infected areas. Their cellulase activities were measured by endoglucanase activity, β-glucosidase activity, and filter paper activity assays. Safety analyses of the Trichoderma isolates were conducted by inoculating them into banana plantlets. The antagonistic effects of the Trichoderma spp on the Fusarium pathogen Foc tropical Race 4 (Foc TR4) were tested by the dual culture technique. Four isolates that had high cellulase activity, no observable pathogenicity to banana plants, and high antagonistic capability were identified. The isolates were used to biodegrade diseased banana plants infected with GFP-tagged Foc TR4, and the compost was tested for biological control of the infectious agent; the results showed that the fermentation suppressed the incidence of wilt and killed the pathogen. This study indicates that Trichoderma isolates have the potential to eliminate the transmission of Foc TR4, and may be developed into an environmentally sustainable treatment for controlling Fusarium wilt in banana plants.

Commentary on the Federal Government's Role in Influencing E-prescribing Use and Research

PubMed Central

Odukoya, Olufunmilola K; Chui, Michelle A

2012-01-01

Electronic prescribing (e-prescribing) is one of the most studied areas of health information technology due to advocacy for its use by influential organizations such as the Institute of Medicine (IOM). In the United States, the federal government has played a significant role in encouraging use of e-prescribing technology and in stimulating associated research nationwide. The federal government has increased e-prescribing research initiatives through agencies such as the Agency for Healthcare Research and Quality (AHRQ) and the Health Resources and Services Administration (HRSA). Initial initiatives focused on the development of standards for e-prescribing systems and implementation. In recent times, e-prescribing research initiatives have become more focused on identifying unintended consequences of using this technology and identifying new possibilities of use that were previously not envisioned. Continuous studies of how healthcare professionals are interfacing with this new technology, how systems have been implemented, and the impact of this technology on healthcare processes and outcomes are crucial.

General practitioner (GP) prescribing accounts for about 10% of NHS expenditure. GPs at the top of the range have annual prescribing costs that are almost twice as much as those at the bottom of the range. This variation cannot be accounted for purely in terms of differences in underlying need for health care. To describe the relationship between GPs' prescribing costs and their attitudes towards prescribing decisions and prescribing information sources, and to identify potentially modifiable attitudinal and behavioural factors associated with high cost prescribing. A postal questionnaire was designed on the basis of hypotheses developed from a literature search and an earlier qualitative survey. This questionnaire was sent to a national sample of GPs with equal numbers of practices in the upper, middle, and lowest quintile of prescribing costs. GP practices in England. 1714 GPs in NHS practice. GPs' self-reported practices, attitudes and personal characteristics. There was a 64% response rate. Responders were more likely to be from larger practices, in less deprived areas, and with lower prescribing costs than were non-responders. Multivariable analysis showed that GPs with high prescribing costs were significantly more likely to work in dispensing practices, in practices with low income populations, in single handed practices, and in practices without a GP trainer. They were also significantly more likely to see drug company representatives more frequently, to prescribe newly available drugs more freely, to prescribe more readily to patients who expect a prescription, to report high levels of frustration from lack of time in the consultation, to find unsatisfactory those consultations which ended in advice only, and to express dissatisfaction with their review methods for repeat prescribing. They were significantly less likely to find useful criticism of prescribing habits by colleagues, and to check the BNF rather than other sources when uncertain about an

The structure of DSM-IV-TR personality disorder diagnoses in NESARC: a reanalysis.

2013-12-01

Cox, Clara, Worobec, and Grant (2012) recently presented results from a series of analyses aimed at identifying the factor structure underlying the DSM-IV-TR (APA, 2000) personality diagnoses assessed in the large NESARC study. Cox et al. (2012) concluded that the best fitting model was one that modeled three lower-order factors (the three clusters of PDs as outlined by DSM-IV-TR), which in turn loaded on a single PD higher-order factor. Our reanalyses of the NESARC Wave 1 and Wave 2 data for personality disorder diagnoses revealed that the best fitting model was that of a general PD factor that spans each of the ten DSM-IV PD diagnoses, and our reanalyses do not support the three-cluster hierarchical structure outlined by Cox et al. (2012) and DSM-IV-TR. Finally, we note the importance of modeling the Wave 2 assessment method factor in analyses of NESARC PD data.

Recently, more women were provided with 6-mercaptopurine (6-MP) during pregnancy. Therefore, we attempted to clarify the transport mechanisms of 6-MP through blood-placenta barrier using rat conditionally immortalized syncytiotrophoblast cell lines (TR-TBTs). The uptake of 6-MP was time- and ATP dependent, but sodium independent in TR-TBTs. 6-MP was eliminated over 50% from the cells within 30 min. The uptake of 6-MP was saturable with Michaelis-Menten constant values of 198 μM and 250 μM in TR-TBT 18d-1 and TR-TBT 18d-2, respectively. 6-Thioguanine, azathioprine, and hypoxantine, structural analogues of 6-MP, strongly inhibited [(14) C]6-MP uptake. Equilibrative nucleoside transporter (ENT) inhibitors, adenosine and uridine, significantly inhibited [(14) C]6-MP uptake. However, several organic anions and cations had no effect on [(14) C]6-MP uptake in TR-TBTs. These results suggest that sodium-independent transporters, ENTs, may be involved in 6-MP uptake at the placenta. In addition, multidrug resistance protein (MRP) inhibitors, methotrexate, probenecid, cefmetazole, and sulfinpyrazone, significantly increased the accumulation of [(14) C]6-MP in the cells. It is indicated that 6-MP may be eliminated across the blood-placental barrier via MRPs. TR-TBTs expressed mRNA of ENT1, ENT2, MRP4, and MRP5. These findings are important for the therapy of acute lymphoblastic leukemia and autoimmune diseases of pregnant women, and should be useful data in elucidating teratogenicity of 6-MP during pregnancy.

In bioaugmentation technology, survival of inoculant in the treatment system is prerequisite but remains to be a crucial hurdle. In this study, we bioaugmented the denitrification tank of a piggery wastewater treatment system with the denitrifying bacterium Pseudomonas stutzeri strain TR2 in two pilot-scale experiments, with the aim of reducing nitrous oxide (N(2)O), a gas of environmental concern. In the laboratory, strain TR2 grew well and survived with high concentrations of nitrite (5-10 mM) at a wide range of temperatures (28-40°C). In the first augmentation of the pilot-scale experiment, strain TR2 inoculated into the denitrification tank with conditions (30°C, ~0.1 mM nitrite) survived only 2-5 days. In contrast, in the second augmentation with conditions determined to be favorable for the growth of the bacterium in the laboratory (40-45°C, 2-5 mM nitrite), strain TR2 survived longer than 32 days. During the time when the presence of strain TR2 was confirmed by quantitative real-time PCR, N(2)O emission was maintained at a low level even under nitrite-accumulating conditions in the denitrification and nitrification tanks, which provided indirect evidence that strain TR2 can reduce N(2)O in the pilot-scale system. Our results documented the effective application of growth conditions favorable for strain TR2 determined in the laboratory to maintain growth and performance of this strain in the pilot-scale reactor system and the decrease of N(2)O emission as the consequence.

Previous research developed a new method for locating prescribing errors in rapidly discontinued electronic medication orders. Although effective, the prospective design of that research hinders its feasibility for regular use. Our objectives were to assess a method to retrospectively detect prescribing errors, to characterize the identified errors, and to identify potential improvement opportunities. Electronically submitted medication orders from 28 randomly selected days that were discontinued within 120 minutes of submission were reviewed and categorized as most likely errors, nonerrors, or not enough information to determine status. Identified errors were evaluated by amount of time elapsed from original submission to discontinuation, error type, staff position, and potential clinical significance. Pearson's chi-square test was used to compare rates of errors across prescriber types. In all, 147 errors were identified in 305 medication orders. The method was most effective for orders that were discontinued within 90 minutes. Duplicate orders were most common; physicians in training had the highest error rate ( p  < 0.001), and 24 errors were potentially clinically significant. None of the errors were voluntarily reported. It is possible to identify prescribing errors in rapidly discontinued medication orders by using retrospective methods that do not require interrupting prescribers to discuss order details. Future research could validate our methods in different clinical settings. Regular use of this measure could help determine the causes of prescribing errors, track performance, and identify and evaluate interventions to improve prescribing systems and processes.

Prescribed burning impact on forest soil properties--a Fuzzy Boolean Nets approach.

Castro, Ana C Meira; Paulo Carvalho, Joao; Ribeiro, S

2011-02-01

The Portuguese northern forests are often and severely affected by wildfires during the Summer season. These occurrences significantly affect and negatively impact all ecosystems, namely soil, fauna and flora. In order to reduce the occurrences of natural wildfires, some measures to control the availability of fuel mass are regularly implemented. Those preventive actions concern mainly prescribed burnings and vegetation pruning. This work reports on the impact of a prescribed burning on several forest soil properties, namely pH, soil moisture, organic matter content and iron content, by monitoring the soil self-recovery capabilities during a one year span. The experiments were carried out in soil cover over a natural site of Andaluzitic schist, in Gramelas, Caminha, Portugal, which was kept intact from prescribed burnings during a period of four years. Soil samples were collected from five plots at three different layers (0-3, 3-6 and 6-18) 1 day before prescribed fire and at regular intervals after the prescribed fire. This paper presents an approach where Fuzzy Boolean Nets (FBN) and Fuzzy reasoning are used to extract qualitative knowledge regarding the effect of prescribed fire burning on soil properties. FBN were chosen due to the scarcity on available quantitative data. The results showed that soil properties were affected by prescribed burning practice and were unable to recover their initial values after one year. Copyright © 2010 Elsevier Inc.

2016-01-01

Objective To understand the professional and psychosocial factors that influence physicians' antibiotic-prescribing habits in the inpatient setting. Design We conducted semi-structured interviews with 30 inpatient physicians. Interviews consisted of open-ended questions and flexible probes based on participants' responses. Interviews were audio recorded, transcribed, de-identified, and reviewed for accuracy and completeness. Data were analyzed using emergent thematic analysis. Setting Two teaching hospitals in Indianapolis, IN Participants Thirty inpatient physicians (10 physicians-in-training, 20 supervising staff) Results Participants recognized that antibiotics are over-used, and many admitted to prescribing antibiotics even when the clinical evidence of infection was uncertain. Over-prescription was largely driven by anxiety about missing an infection while potential adverse effects of antibiotics did not strongly influence decision-making. Participants did not routinely disclose potential adverse effects of antibiotics to inpatients. Physicians-in-training were strongly influenced by the antibiotic prescribing behavior of their supervising staff physicians. Participants sometimes questioned their colleagues' antibiotic-prescribing decisions but frequently avoided providing direct feedback or critique, citing obstacles of hierarchy, infrequent face-to-face encounters, and the awkwardness of these conversations. Conclusion There is a physician-based culture of prescribing antibiotics, which involves over-using antibiotics and not challenging colleagues' decisions. The potential adverse effects of antibiotics do not strongly influence decision-making in this sample. A better understanding of these factors could be leveraged in future efforts to improve antibiotic-prescribing in the inpatient setting. PMID:26078017

This study describes the taxonomy of methods used by pharmaceutical companies to influence physicians’ NSAID prescribing behaviors and elicits physicians’ perceptions of and counter-balances to these influences. Study Design In-depth interviews analyzed using the constant comparative method of qualitative data analysis. Methods Qualitative interviews were conducted with physicians representing various clinical specialties. Interviews were transcribed and coded inductively using grounded theory. Recruitment was stopped at 25 participants after the attainment of thematic saturation, when no new concepts emerged from ongoing analysis of consecutive interviews. Results Physicians described a variety of influences that shaped their NSAID prescribing behaviors, including detailing and direct contact with pharmaceutical representatives, requests from patients inspired by direct-to-consumer advertisements, and marketing during medical school and residency training. Physicians described practice guidelines, peer-reviewed evidence and opinions of local physician experts as important counterweights to pharmaceutical company influence. Local physician experts interpreted and provided context for new clinical evidence, practice guidelines and NSAID related marketing. Conclusions The social and communicative strategies used by pharmaceutical companies can be adapted to improve physicians’ adoption of guidelines for safer NSAID prescribing. The communicative interactions between local experts and other physicians who prescribe NSAIDs may be the critical target for future interventions to promote safer NSAID prescribing. PMID:19341315

Because the longleaf ecosystem evolved with and is adapted to frequent fire, every 2 to 8 years, prescribed burning is often useful for restoring understory communities to a diverse ground layer of grasses, herbs, and small shrubs. This restoration provides habitat for a number of plant and animal species that are restricted to or found mostly in longleaf pine...

Prescribing decisions are a complex phenomenon and influenced by many pharmacological and non-pharmacological factors. Little is known about the actual prescribing behaviors of physicians or the factors behind their prescribing decisions. The objective of this study was to explore the factors that influence physicians' prescribing decisions and the role of the marketing activities by pharmaceutical companies in this decision-making process. A semi-structured interview with the critical incident technique method was used to encourage physicians to describe the particular situations of prescribing for specific newly marketed drugs. All interviews were transcribed verbatim and thematic content analysis with systematic and comprehensive coding was employed to identify categories of physicians' reasons for either prescribing or not of the study drugs. Factors that influence prescribing of the study drugs (223 critical incidents) were categorized in six major themes. Drug characteristics, the most frequently mentioned by physicians as reasons of prescribe, were implicated in 70 (31.4%) incidents, followed by pharmaceutical company mentioned in 53 (23.8%) incidents, indications, 31 (13.9%) incidents, and patient contexts, 26 (11.7%) incidents. Environmental factors as information and evidence were implicated in 22 (9.9%) incidents, and physician factor, 21 (9.4%) incidents. Prescribing is a complex process and physicians integrate different factors. Although physicians make a considerable on patient contexts and treatment outcomes, they still rely on their personal experiences when making prescribing in addition to firms' source of information and firms' marketing activities.

This study explored the lived experiences of clinical nurse specialists who can prescribe independently in their role of providing support to patients with palliative care needs within the community. Part 1 of this study examined how the study was carried out; this second part explores the findings. The nurses reported that being able to prescribe enabled them to provide seamless, holistic care, which gave patients faster access to medicines, especially at weekends when their GP was unavailable. Prompt availability of medicines led to effective symptom control and consequently a better quality of life for patients. The main barrier to prescribing was difficulty in accessing patient records. Independent prescribing by community nurse specialists is beneficial for patients receiving palliative care and their families while they are being cared for at home, and provides job satisfaction for the nurses.

Background Recent studies on prescribing among outpatients in hospitals in Western Nepal are lacking. The main objectives of the study were to obtain information on the morbidity pattern among outpatients and to analyze prescribing using drug use indicators. Methods A retrospective hospital record based study from 01.01.2004 to 31.12.2004 was carried out among individuals attending the outpatient department (OPD) of the Manipal Teaching hospital, Pokhara, Western Nepal. A total of 32,017 new patients attended the OPD during the study period. Systematic random sampling (1 in every 20 patients) was done and 1600 patients selected. After excluding patients visiting the emergency department, those who got admitted and whose records were not available, 1261 cases were analyzed. The demographic details, morbidity pattern, average number of drugs prescribed, percentage of drugs prescribed by generic names and from the Essential drug list of Nepal (Essential drugs are those which satisfy the priority healthcare needs of the population), percentage of encounters with an antibiotic and an injection prescribed were noted. Results 1261 patients made 1772 visits. Upper respiratory tract infection and acid peptic disease were the most common diagnoses. The mean number of drugs was 1.99. Only 19.5% and 39.6% of drugs were prescribed by generic name and from the Essential drug list. Antibiotics and injections were prescribed in 26.4% and 0.96% of encounters. Cetrizine, vitamins, amoxicillin, the combination of paracetamol and ibuprofen and ranitidine were most commonly prescribed. Conclusions Upper respiratory tract infections and acid peptic disease were the common illnesses. Generic prescribing and use of essential drugs were low. Some of the drug combinations being used were irrational. Prescriber education may be helpful in encouraging rational prescribing. PMID:18523618

Insight into factors that influence antibiotic prescribing is crucial when developing interventions aimed at a more rational use of antibiotics. We examined factors that influence antibiotic prescribing in long-term care facilities, and present a conceptual model that integrates these factors. Semi-structured qualitative interviews were conducted with physicians (n = 13) and nursing staff (n = 13) in five nursing homes and two residential care homes in the central-west region of the Netherlands. An iterative analysis was applied to interviews with physicians to identify and categorize factors that influence antibiotic prescribing, and to integrate these into a conceptual model. This conceptual model was triangulated with the perspectives of nursing staff. The analysis resulted in the identification of six categories of factors that can influence the antibiotic prescribing decision: the clinical situation, advance care plans, utilization of diagnostic resources, physicians' perceived risks, influence of others, and influence of the environment. Each category comprises several factors that may influence the decision to prescribe or not prescribe antibiotics directly (e.g. pressure of patients' family leading to antibiotic prescribing) or indirectly via influence on other factors (e.g. unfamiliarity with patients resulting in a higher physician perceived risk of non-treatment, in turn resulting in a higher tendency to prescribe antibiotics). Our interview study shows that several non-rational factors may affect antibiotic prescribing decision making in long-term care facilities, suggesting opportunities to reduce inappropriate antibiotic use. We developed a conceptual model that integrates the identified categories of influencing factors and shows the relationships between those categories. This model may be used as a practical tool in long-term care facilities to identify local factors potentially leading to inappropriate prescribing, and to subsequently

General Medical Practitioners (GPs) in the United Kingdom are usually the first point of contact with the National Health Service (NHS) for patients. They provide the majority of ambulatory care for their practice population and act as 'gatekeepers' for referral onwards to other services. This article investigates the influence of the purchasing authority prescribing advisors (PAs), including pharmacists and GPs on the prescribing habits in Salford, England, an inner city area in the North of England, close to the city of Manchester. The PAs became known as the prescribing CIA, and used the strategy of Control, progressing to Influence and Autonomy, to develop a mature partnership between the GPs, PAs and other health care professionals. Information collated from prescribing (PACT) data, by the Prescription Pricing Authority, was used to make comparisons between different practices within an area. Savings made by making rational changes in prescribing, were used to enhance practice development for the benefit of patient care.

Spectacles are routinely prescribed by the ophthalmologist and dispensed by the opticians. We investigated how frequently the spectacles are not dispensed as prescribed and whether the frequency of inaccurate spectacles would decrease if the patients, at the time of collecting spectacles, ask the optician to verify that the spectacles have been dispensed accurately. We found inaccurate spectacles in about one-third of our patients and incorrect spherocylinders more frequently with an error in the spherical element and cylinder axis. These inaccuracies decreased significantly when patients while collecting spectacles, asked the optician to verify the accuracy of the spectacles dispensed. It is suggested that while prescribing spectacles, the patients should be made aware of the possibility of dispensing errors. To decrease the frequency of incorrect spectacles, the patients while collecting spectacles, should ask the optician to check whether the spectacles have been dispensed accurately.
