Differences between physicians' and nurse practitioners' viewpoints on reasons for clozapine underprescription.

ABSTRACT: INTRODUCTION:Clozapine (CLZ) is the only proven effective therapy for treatment-resistant schizophrenia, but it is underutilized across the globe. Previous findings suggest a lack of experience with CLZ prescription and concerns about CLZ's pharmacological characteristics are the prime reasons for CLZ underutilization. To our knowledge, it is currently unknown whether the reasons for underutilization and suggested solutions differ between physicians and nurse practitioners. Such differences are important as nurse practitioners are becoming increasingly involved in prescribing CLZ. METHODS:To examine to what degree physicians and nurse practitioners differ with regard to their take on reasons for CLZ underutilization and suggested solutions, an online questionnaire was distributed to physicians and nurse practitioners. The primary outcome was to compare the patient-related and prescriber-related reasons for CLZ underprescription between physicians and nurse practitioners, while secondary outcome measures included the potential solutions to prevent this underprescription. RESULTS:Physicians (N = 112) and nurse practitioners (N = 41) agreed that the two most common reasons for underprescription (patient-related and prescriber-related) were refusal to undergo regular blood tests and side-effect concerns. They also agreed that the third most common prescriber-related reason was medical complications. Physicians rated patients' unwillingness to switch medication as the third most common reason for CLZ underprescription, whereas nurse practitioners rated refusal to undergo baseline bloodtests as the third most common reason. The solutions to reduce underprescription largely corresponded between both groups. CONCLUSIONS:We conclude that slight differences exist between physicians' and nurse practitioners' viewpoints on patient-related and prescriber-related reasons for CLZ underprescription. Future research projects should involve patients to elucidate whether the patient-related factors put forward by prescribers align with the patients' opinions.

Project description:ObjectivesThis study aimed to gain insight into how substitution of elderly care physicians (ECPs) by nurse practitioners (NPs), physician assistants (PAs) or registered nurses (RNs) in nursing homes is modelled in different contexts and what model in what context contributes to perceived quality of healthcare. Second, this study aimed to provide insight into elements that contribute to an optimal model of substitution of ECPs by NPs, PAs or RNs.DesignA multiple-case study was conducted that draws on realist evaluation principles.SettingSeven nursing homes in the Netherlands PARTICIPANTS: The primary participants were NPs (n=3), PAs (n=2) and RNs (n=2), working in seven different nursing homes and secondary participants were included; ECPs (n=15), medical doctors (MDs) (n=2), managing directors/managers/supervisors (n=11), nursing team members (n=33) and residents/relatives (n=78).Data collectionData collection consisted of: (1) observations of the NP/PA/RN and an ECP/MD, (2) interviews with all participants, (3) questionnaires filled out by the NP/PA/RN, ECPs/MDs and managing directors/managers and (4) collecting internal policy documents.ResultsAn optimal model of substitution of ECPs seems to be one in which the professional substitutes for the ECP largely autonomously, well-balanced collaboration occurs between the ECP and the substitute, and quality of healthcare is maintained. This model was seen in two NP cases and one PA case. Elements that enabled NPs and PAs to work according to this optimal model were among others: collaborating with the ECP based on trust; being proactive, decisive and communicative and being empowered by organisational leaders to work as an independent professional.ConclusionsCollaboration based on trust between the ECP and the NP or PA is a key element of successful substitution of ECPs. NPs, PAs and RNs in nursing homes may all be valuable in their own unique way, matching their profession, education and competences.

Project description:IntroductionIn developed countries, substituting physicians with nurse practitioners, physician assistants and nurses (physician substitution) occurs in nursing homes as an answer to the challenges related to the ageing population and the shortage of staff, as well as to guarantee the quality of nursing home care. However, there is great diversity in how physician substitution in nursing homes is modelled and it is unknown how it can best contribute to the quality of healthcare. This study aims to gain insight into how physician substitution is modelled and whether it contributes to perceived quality of healthcare. Second, this study aims to provide insight into the elements of physician substitution that contribute to quality of healthcare.Methods and analysisThis study will use a multiple-case study design that draws upon realist evaluation principles. The realist evaluation is based on four concepts for explaining and understanding interventions: context, mechanism, outcome and context-mechanism-outcome configuration. The following steps will be taken: (1) developing a theory, (2) conducting seven case studies, (3) analysing outcome patterns after each case and a cross-case analysis at the end and (4) revising the initial theory.Ethics and disseminationThe research ethics committee of the region Arnhem Nijmegen in the Netherlands concluded that this study does not fall within the scope of the Dutch Medical Research Involving Human Subjects Act (WMO) (registration number 2015/1914). Before the start of the study, the Board of Directors of the nursing home organisations will be informed verbally and by letter and will also be asked for informed consent. In addition, all participants will be informed verbally and by letter and will be asked for informed consent. Findings will be disseminated by publication in a peer-reviewed journal, international and national conferences, national professional associations and policy partners in national government.
