Computational models of reinforcement learning have helped dissect discrete components of reward-related function and characterize neurocognitive deficits in psychiatric illnesses. Stimulus novelty biases decision-making, even when unrelated to choice outcome, acting as if possessing intrinsic reward value to guide decisions toward uncertain options. Heightened novelty seeking is characteristic of attention deficit hyperactivity disorder, yet how this influences reward-related decision-making is computationally encoded, or is altered by stimulant medication, is currently uncertain...

Objective: Available studies on implementation of evidence-based psychotherapy (EBP) for patients attending Department of Veterans Affairs (VA) residential post-traumatic stress disorder (PTSD) programs rely on therapist self-report of EBP delivery. Patient-level data on receipt of EBP are needed both to corroborate therapist self-report and to understand patient factors that predict receipt of EBPs for PTSD. Materials and Methods: We identified 159 therapists from 38 VA residential PTSD programs who responded to a survey about EBP implementation during the 2015 fiscal year (FY15)...

In 1999, the Institute of Medicine reported that 98,000 people die each year due to medical errors. In the following years, the focus on hospital quality was intensified nationally, with policymakers providing evidence-based practice guidelines for improving health care quality. However, these innovations (evidence-based guidelines) that were being produced at policy levels were not translating to clinical practice at the hospital organizational level easily, and stark variations continued to persist, in the quality of health care...

Studies of adult patients have demonstrated that weekend admissions compared with weekday admissions had a significantly higher hospital mortality rate. We have reviewed the literature to determine if the timing of admission, for example, weekend or weekday, influenced mortality and morbidity in children. Seventeen studies reported the effect of timing of admission on mortality, and only four studies demonstrated an increase in those admitted at the weekend. Meta-analysis of the results of 15 of the studies demonstrated there was no significant weekend effect...

BACKGROUND: Patient safety measurement remains a global challenge. Patients are an important but neglected source of learning; however, little is known about what patients can add to our understanding of safety. We sought to understand the incidence and nature of patient-reported safety concerns in hospital. METHODS: Feedback about the experience of safety within hospital was gathered from 2471 inpatients as part of a multicentre, waitlist cluster randomised controlled trial of an intervention, undertaken within 33 wards across three English NHS Trusts, between May 2013 and September 2014...

Clinical pharmacists should be increasingly important members of the healthcare team in developing countries such as Pakistan. Survey of literature was conducted to identify the determinants of clinical pharmacy in Pakistan. Lack of trained human capital, shortage of resources, patient overburden, inefficient pharmacy education curriculum, and limited job opportunities are some of the determinants of clinical pharmacy profession in developing countries. The underutilization of clinical pharmacists paves the way for an increased incidence of medication errors, adverse drug events, irrational prescribing, and suboptimal therapeutic outcomes...

To date, a large amount of retrospectively collected data about treatment of neurosurgical pathology have been accumulated. Modern methods of medical statistics are necessary for correct interpretation of the data. The article purpose is to demonstrate application of one of the modern methods, Propensity Score Matching (PSM), in neurosurgery. The use of PSM avoids misinterpretation of retrospectively collected data and obviates errors in planning further prospective studies. For the past 10 years, the number of published international PSM-based studies has increased more than 10-fold, with the number of articles by Russian authors accounting for less than 0...

The Netherlands Medicines Evaluation Board (MEB) was recently informed about a serious pipamperone overdose in a 6-year-old boy, which happened because the boy was given the medication in streams rather than in drops. This article describes the use of drops in pharmaceutical patient care and explains why the MEB has maintained marketing authorization for the product on the basis of currently available information. The MEB urgently requests the healthcare professional groups to report all problems concerning drug use to the Netherlands Pharmacovigilance Centre Lareb, and the Portal for Patient Safety; this is the only way in which it can be verified whether incidental medication errors are actually, and continue to be, incidental...

BACKGROUND: Medication is not always delivered in a safe dosing format. Up to 33% of medication errors can be attributed to confusing packaging or labelling. CASE DESCRIPTION: A 6-year-old boy with ADHD, for which he was being treated with methylphenidate and pipamperone drops, was brought to the A&E department with signs of severe encephalopathy. He had apparently been given pipamperone in streams rather than in drops in the previous months. The pipamperone level in his blood was raised to toxic levels...

OBJECTIVES: In undergraduate medical education, the topics of errors in medicine and patient safety are under-represented. The aim of this study was to explore undergraduate medical students' behavioural intentions when confronted with an error. DESIGN: A qualitative case vignette survey was conducted including one of six randomly distributed case scenarios in which a hypothetical but realistic medical error occurred. The six scenarios differed regarding (1) who caused the error, (2) the presence of witnesses and (3) the consequences of the error for the patient...

BACKGROUND: One of the central challenges of third millennium medicine is the abatement of medical errors. Among the most frequent and hardiest causes of misdiagnosis are cognitive errors produced by faulty medical reasoning. These errors have been analyzed from the perspectives of cognitive psychology and empirical medical studies. We introduce a neurocognitive model of medical diagnosis to address this issue. METHODS: We construct a connectionist model based on the associative nature of human memory to explore the non-analytical, pattern-recognition mode of diagnosis...
