An Application of the Multi-Level Heuristic for the Heterogeneous Fleet Vehicle Routing Problem
The Multi-Level heuristic is used to investigate the heterogeneous fleet vehicle routing problem (HFVRP). The initial solution for the Multi-Level heuristic is obtained by Dijkstra\u27s algorithm based on a cost network constructed by the sweep algorithm and the 2-opt procedure. The proposed algorithm uses a number of local search operators such as swap, 1-0 insertion, 2-opt, and Dijkstra\u27s Algorithm. In addition, in order to improve the search process, a diversification procedure is applied. The proposed algorithm is thentested on the data sets from the literature
Patients with Cluster A Personality Disorders in Psychotherapy: An Effectiveness Study
Abstract BACKGROUND: While psychopharmacological studies are common in patients with cluster A personality disorders, the effects of psychotherapy have received little attention. The aim of this study is to explore whether psychotherapeutic treatment yields health gains for these patients. METHODS: The study was conducted between March 2003 and June 2008 in 6 mental health care centres in the Netherlands, with a sample of 57 patients with a DSM-IV-TR axis II cluster A diagnosis. Patients were assigned to 3 settings of psychotherapeutic treatment (outpatient, day hospital, inpatient), and effectiveness was assessed at 18 months after baseline. An intention-to-treat analysis was conducted for psychiatric symptoms (Brief Symptom Inventory), psychosocial functioning (Outcome Questionnaire-45) and quality of life (EQ-5D), using multilevel statistical modelling. As the study was non-randomised, the propensity score method was used to control for initial differences. RESULTS: Patients in the day hospital and inpatient group improved substantially in terms of psychiatric symptoms, social and interpersonal functioning, and quality of life. Patients in the outpatient group showed less improvement. Direct comparison of the improvement of psychiatric symptoms showed significant results in favour of day hospital (p = 0.046) and inpatient (p = 0.01) treatment, as compared to outpatient treatment. However, due to substantial baseline differences, this direct comparison should be judged carefully. CONCLUSIONS: Cluster A psychopathology is not a contraindication to benefit from psychotherapy. This is especially true for more intensive forms like inpatient and day hospital treatment. Future research should focus more on psychotherapeutic treatment to gain further insight into effective treatment options for this patient grou

Rationale, design and conduct of a randomised controlled trial evaluating a primary care-based complex intervention to improve the quality of life of heart failure patients: HICMan (Heidelberg Integrated Case Management) : study protocol
Background: Chronic congestive heart failure (CHF) is a complex disease with rising prevalence, compromised quality of life (QoL), unplanned hospital admissions, high mortality and therefore high burden of illness. The delivery of care for these patients has been criticized and new strategies addressing crucial domains of care have been shown to be effective on patients' health outcomes, although these trials were conducted in secondary care or in highly organised Health Maintenance Organisations. It remains unclear whether a comprehensive primary care-based case management for the treating general practitioner (GP) can improve patients' QoL. Methods/Design: HICMan is a randomised controlled trial with patients as the unit of randomisation. Aim is to evaluate a structured, standardized and comprehensive complex intervention for patients with CHF in a 12-months follow-up trial. Patients from intervention group receive specific patient leaflets and documentation booklets as well as regular monitoring and screening by a prior trained practice nurse, who gives feedback to the GP upon urgency. Monitoring and screening address aspects of disease-specific selfmanagement, (non)pharmacological adherence and psychosomatic and geriatric comorbidity. GPs are invited to provide a tailored structured counselling 4 times during the trial and receive an additional feedback on pharmacotherapy relevant to prognosis (data of baseline documentation). Patients from control group receive usual care by their GPs, who were introduced to guidelineoriented management and a tailored health counselling concept. Main outcome measurement for patients' QoL is the scale physical functioning of the SF-36 health questionnaire in a 12-month follow-up. Secondary outcomes are the disease specific QoL measured by the Kansas City Cardiomyopathy questionnaire (KCCQ), depression and anxiety disorders (PHQ-9, GAD-7), adherence (EHFScBS and SANA), quality of care measured by an adapted version of the Patient Chronic Illness Assessment of Care questionnaire (PACIC) and NTproBNP. In addition, comprehensive clinical data are collected about health status, comorbidity, medication and health care utilisation. Discussion: As the targeted patient group is mostly cared for and treated by GPs, a comprehensive primary care-based guideline implementation including somatic, psychosomatic and organisational aspects of the delivery of care (HICMAn) is a promising intervention applying proven strategies for optimal care.

Clinical reasoning by pharmacists: A scoping review
BACKGROUND: Clinical reasoning is considered a core competency for pharmacists, but there is a lack of conceptual clarity that complicates teaching and assessment. This scoping review was conducted to identify, map, and examine evidence on used cognitive processes and their conceptualization of clinical reasoning by pharmacists. METHODS: In March 2021, seven databases were searched for relevant primary research studies. Included were studies that examined cognitive processes in pharmacists while addressing a clinical scenario in a pharmacy-related setting. Using descriptive analysis, study characteristics, conceptualizations, operationalizations, and key findings were mapped, summarized, and examined. Results were reported using Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. RESULTS: From 2252 abstracts, 17 studies were included that examined clinical reasoning in the context of forming a diagnosis (n = 9) or determining medication appropriateness (n = 4). Most studies conceptualized clinical reasoning as a context-dependent cognitive process whereby pharmacists apply and integrate knowledge and clinical experience to interpret available clinical data. Different terms labelled pharmacists' reasoning that showed analytical and intuitive approaches to clinical scenarios, either separately or combined. Medication review studies reported a predominance of analytical reasoning. The majority of diagnosis-forming studies in primary care identified no distinct cognitive reasoning pattern when addressing self-care scenarios. IMPLICATIONS: This overview reflects a small but growing body of research on clinical reasoning by pharmacists. It is recommended that this competence be taught by explicating and reflecting on clinical reasoning as separate stage of the clinical decision-making process with transparent cognitive processes
Factors influencing pharmacists' clinical decision making in pharmacy practice
BACKGROUND: Pharmacists' clinical decision-making is considered a core process of pharmaceutical care in pharmacy practice, but little is known about the factors influencing this process. OBJECTIVE: To identify factors influencing clinical decision-making among pharmacists working in pharmacy practice. METHODS: Semi-structured interviews were conducted with pharmacists working in primary, secondary, and tertiary care settings in the Netherlands between August and December 2021. A thematic analysis was conducted using an inductive approach. The emerged themes were categorized into the Capability-Opportunity-Motivation-Behaviour (COM-B) model domains. RESULTS: In total, 16 pharmacists working in primary care (n = 7), secondary care (n = 4) or tertiary care (n = 5) were interviewed. Factors influencing pharmacists' capability to make clinical decisions are a broad theoretical knowledge base, clinical experience, and skills, including contextualizing data, clinical reasoning, and clinical judgment. The pharmacy setting, data availability, rules and regulations, intra- and interprofessional collaboration, education, patient perspectives, and time are mentioned as factors influencing their opportunity. Factors influencing pharmacists' motivation are confidence, curiosity, critical thinking, and responsibility. CONCLUSIONS: The reported factors covered all domains of the COM-B model, implying that clinical decision-making is influenced by a combination of pharmacists' capability, opportunity, and motivation. Addressing these different factors in pharmacy practice and education may improve pharmacists' clinical decision-making, thereby improving patient outcomes
Patients' Perspectives on the Development of Prescription Opioid Use Disorder in Patients with Chronic Non-Cancer Pain
INTRODUCTION: In the past decade, prescription opioid use increased exponentially and concomitantly opioid use disorders (OUD) are becoming more common. Several risk factors for developing OUD have been identified, but little is known regarding the patients' perspective on developing a prescription OUD. METHODS: We recruited 25 adults undergoing treatment for prescription OUD. In-depth, semi-structured interviews focussed on experiences with long-term opioid use, knowledge and attitudes regarding opioids, and access to opioids. A directed content analysis was conducted on the transcribed interviews using NVivo. RESULTS: Participants showed that the development of an OUD is affected by various factors which could be grouped into three themes: (1) experiences driving initiation, (2) experiences driving continuation, and (3) experiences with prescription OUD. Besides the need for pain management, the dynamics of patient-provider communication, care coordination, provider vigilance, and environmental support all contributed to the way patients used their opioids. CONCLUSION: Patients' experiences illustrate that the first stage of the development of prescription OUD differs from the development of other substance addictions. Negative reinforcement might play a more prominent role in the early phase of prescription opioid use. Patients expressed a lack of guidance, both at the start of use and long-term use, easy access to new prescriptions and a lack of monitoring as main drivers of the development. Poorly controlled pain and subjective stress fuelled continuous opioid use
Validity evidence for summative performance evaluations in postgraduate community pharmacy education
Introduction: Workplace-based assessment of competencies is complex. In this study, the validity of summative performance evaluations (SPEs) made by supervisors in a two-year longitudinal supervisor-trainee relationship was investigated in a postgraduate community pharmacy specialization program in the Netherlands. The construct of competence was based on an adapted version of the 2005 Canadian Medical Education Directive for Specialists (CanMEDS) framework. Methods: The study had a case study design. Both quantitative and qualitative data were collected. The year 1 and year 2 SPE scores of 342 trainees were analyzed using confirmatory factor analysis and generalizability theory. Semi-structured interviews were held with 15 supervisors and the program director to analyze the inferences they made and the impact of SPE scores on the decision-making process. Results: A good model fit was found for the adapted CanMEDS based seven-factor construct. The reliability/precision of the SPE measurements could not be completely isolated, as every trainee was trained in one pharmacy and evaluated by one supervisor. Qualitative analysis revealed that supervisors varied in their standards for scoring competencies. Some supervisors were reluctant to fail trainees. The competency scores had little impact on the high-stakes decision made by the program director. Conclusions: The adapted CanMEDS competency framework provided a valid structure to measure competence. The reliability/precision of SPE measurements could not be established and the SPE measurements provided limited input for the decision-making process. Indications of a shadow assessment system in the pharmacies need further investigation
Pharmacists and pharmacy students' perceptions on how a new teaching model supports their clinical decision-making
Background and purpose: Clinical decision-making (CDM) is crucial in pharmacy practice, necessitating effective teaching in undergraduate and postgraduate pharmacy education. This study aims to explore undergraduates and postgraduates' perceptions of how a new teaching model supports their CDM when addressing patient cases. Educational activity and setting: Implemented in a full-day CDM course for pharmacy students and a half-day course for pharmacists in the Netherlands, the model, accompanied by a learning guide, facilitated CDM in patient cases. Eight courses were conducted between September 2022 to June 2023, followed by an online survey measuring participants' agreement on how the model supported their CDM, using a 5-point Likert scale. Additionally, three open-ended questions were included to elicit learning outcomes and self-development opportunities. Findings: Of 175 invited participants, 159 (91%) completed the survey. Most agreed the teaching model supported their CDM, particularly in considering the patient's healthcare needs and context (96%), and exploring all available options (96%). Participants found the model provided a clear structure (97%), and fostered critical thinking (93%). The most frequently mentioned learning outcomes and self-development opportunities included collecting sufficient relevant information, maintaining a broad perspective, and decelerating the process to avoid premature closure. Participants agreed that the teaching model helped them to make clinical decisions. Both undergraduate and postgraduate pharmacy education could possibly benefit from the teaching model's implementation in supporting pharmacy students and pharmacists conducting CDM in pharmacy practice
