Aim To explore evidence reporting facilitators and barriers to implementation of nurse prescribing and provide practical recommendations for evidence‐informed implementation and adoption of nurse prescribing under a supervision model. Background As demand for access to quality health care services increases, health professional roles are expanding to meet population needs. Nurse prescribing has been effective in some countries and is being considered globally to address growing health care demand. Successful implementation of health service models requires careful planning and consideration. No existing reviews have examined implementation factors in the literature. Design Integrative review. Data sources CINAHL, MEDLINE, PubMed and EMBASE databases were searched from inception to 15 April 2020. Review methods This integrative review is guided by Whittemore and Knafl and adheres to PRISMA reporting guidelines. The sustainability of innovation framework was used to synthesize data concerning implementation and sustainability factors (i.e. innovation, organizational, political, workforce and financial) for nurse prescribing. Results A total of 39 articles were reviewed with literature predominantly reporting findings related to non‐medical and nurse prescribing under various models. Variable evidence was found to inform nurse prescribing across five implementation and sustainability factors identifying several areas that require in‐depth consideration. Very little evidence is available on nurse prescribing under supervision. Conclusion Introduction of service reform is often costly. This review highlights gaps in the literature and raises areas for consideration prior to implementation of this new service delivery model. The introduction of nurse prescribing must be planned and informed by available evidence to support effective adoption, practice and patient outcomes. Impact There are significant gaps in evidence related to nurse prescribing under a supervision model. Based on the evidence synthesized in this review, this paper provides practical recommendations for health service providers, managers, clinicians, educators and researchers to support implementation and adoption of nurse prescribing.
Purpose To examine the perspectives of medical and nursing health professionals concerning their roles and responsibilities in providing dietary and exercise advice to cancer survivors, and referrals to allied health professionals. Methods An integrative review. PubMed, CINAHL, PsycINFO, Embase, Web of Science databases, and bibliographies of relevant studies were searched from December 2011 to June 2021. All studies were eligible for inclusion. The Mixed-Methods Appraisal Tool (MMAT) was used to critically appraise included studies. Data were extracted and synthesised regarding the perspectives of medical and nursing health professionals on their roles, responsibilities, barriers, and facilitators. Results Twenty-one studies involving 3401 medical and nursing health professionals and 264 cancer survivors of diverse cancer types were included. Ten quantitative, nine qualitative, and two mixed-methods studies were eligible. All included studies met at least 80% of the quality criteria in the MMAT. Major findings include the following: (1) medical and nursing health professionals were unclear on their roles in providing dietary and exercise advice to cancer survivors but agreed they play a key role in referrals to dietitians and exercise professionals; (2) most cancer survivors valued the involvement of their general practitioner when receiving dietary and exercise advice. Conclusion Although medical and nursing health professionals understand that referrals to allied health professionals form part of their role, there is a lack of clarity regarding their roles to provide dietary and exercise advice to cancer survivors. Future studies should address barriers and facilitators of dietary and exercise advice and referral by medical and nursing health professionals.
Cancer-associated malnutrition, or cachexia, stemming from cancer or its treatments, is particularly prevalent in metastatic cancers, and is often interrelated with sarcopenia and frailty. Evidence suggests that dietary supplements play a role in managing these conditions. As metastatic cancer cells are associated with notable genomic and phenotypic alterations, response to dietary supplements may differ between metastatic and non-metastatic cancers. However, research in this area is lacking. This scoping review aims to identify the dietary supplements that have been studied in patients with metastatic cancers and malnutrition-related conditions, along with their proposed effects, mechanisms, outcome measures, and tools used. A systematic search was conducted across databases, including MEDLINE, EMBASE, CINAHL, and clinical trial registries. Of the initial 6535 records screened, a total of 48 studies were included, covering a range of dietary supplements—vitamins, minerals, antioxidants, proteins, amino acids, fatty acids, fiber, and others. While the types of dietary supplements included varied across cancer types, omega-3 and carnitine were investigated most often. Proposed relevant attributes of dietary supplements included their antioxidant, anti-inflammatory, anti-cancer, and immunomodulatory properties. Overall, there was a paucity of interventional studies, and more randomized controlled trials are warranted.
Aim:The aim was to explore nurses' preparedness to expand their practice to prescribe medicines under a supervision model. Design:This was a cross-sectional study. Methods: A convenience sample of Australian nurses recruited from memberships of State-based Nursing and Midwifery Unions and professional bodies from diverse care settings. Nurses undertook an online researcher-constructed survey between March and July 2021 to identify current prescribing practices, motivations for undertaking education in prescribing and perceived barriers to implementation of nurse prescribing under supervision. Data related to demographics, nursing experience and barriers to becoming a prescriber were analysed descriptively. Logistic regression was used to model nursing experience variables with desire to become a prescriber.Results: A total of 4424 nurses participated with the majority (n = 3645, 82%) reporting they were highly likely to expand their practice to prescribe medicines under supervision. The main motivations to prescribe were to enhance patient care and job satisfaction. Nurses were more likely to want to prescribe if they had <10 years experience (95% CI = 0.3-0.5, p < 0.001), held a bachelor's degree (95% CI = 1.3-2.2, p < 0.001) or higher qualification (95% CI = 1.8-2.9, p < 0.001). Most reported lack of acknowledgement of increased responsibility and workloads (n = 4098, 93%), and insufficient organizational support (n = 4197, 95%) may prevent uptake of nurse prescribing. Conclusions:Most Australian nurses demonstrated their preparedness to embrace the role of prescribing under supervision. The perceived barriers identified in this study can inform future implementation of this expanded nursing role. Impact:The Nursing and Midwifery Board of Australia has proposed a standard of practice to enable nurses to prescribe under supervision. Models of nurse prescribing are being considered globally to address population needs. Successful adoption of this practice is dependent on aspects such as key personnel's acceptance of the initiative.
