Understanding health professional role integration in complex adaptive systems: a multiple-case study of physician assistants in Ontario, Canada

Factors influencing the development, recruitment, integration, retention and career development of advanced practice providers in hospital health care teams: a scoping review

BACKGROUND

Advanced practice providers (APPs), including physician assistants/associates (PAs), nurse practitioners (NPs) and other non-physician roles, have been developed largely to meet changing healthcare demand and increasing workforce shortages. First introduced in primary care in the US, APPs are prevalent in secondary care across different specialty areas in different countries around the world. In this scoping review, we aimed to summarise the factors influencing the development, recruitment, integration, retention and career development of APP roles in hospital health care teams.

METHODS

We conducted a scoping review and searched Ovid MEDLINE, Ovid Embase, Ovid Global Health, Ovid PsycINFO and EBSCOhost CINAHL to obtain relevant articles published between Jan 2000 and Apr 2023 that focused on workforce management of APP roles in secondary care. Articles were screened by two reviewers independently. Data from included articles were charted and coded iteratively to summarise factors influencing APP development, recruitment, integration, retention and career development across different health system structural levels (macro-, meso- and micro-level).

RESULTS

We identified and analysed 273 articles that originated mostly from high-income countries, e.g. the US (n = 115) and the UK (n = 52), and primarily focused on NP (n = 183) and PA (n = 41). At the macro-level, broader workforce supply, national/regional workforce policies such as work-hour restrictions on physicians, APP scope of practice regulations, and views of external collaborators, stakeholders and public representation of APPs influenced organisations' decisions on developing and managing APP roles. At the meso-level, organisational and departmental characteristics, organisational planning, strategy and policy, availability of resources, local experiences and evidence as well as views and perceptions of local organisational leaders, champions and other departments influenced all stages of APP role management. Lastly at the micro-level, individual APPs' backgrounds and characteristics, clinical team members' perceptions, understanding and relationship with APP roles, and patient perceptions and preferences also influenced how APPs are developed, integrated and retained.

CONCLUSIONS

We summarised a wide range of factors influencing APP role development and management in secondary care teams. We highlighted the importance for organisations to develop context-specific workforce solutions and strategies with long-term investment, significant resource input and transparent processes to tackle evolving healthcare challenges.

Revisiting the unmet mental health needs in Canada: Can PAs be part of the solution?

ABSTRACT

In Canada, unmet mental health care needs remain a major issue despite mental disorders ranking as the second largest source of years lost to disability. As discussions continue on alternative models of healthcare to reduce the long waiting times for mental health treatment, leveraging the skills and resources available from physician associates/assistants (PAs) and NPs becomes imperative. Relatively few PAs in Canada work in psychiatry, despite widespread acceptance in other medical disciplines. Sustainable funding models for the training, recruitment, and retention of PAs in mental health care are vital. More research, policy development, and interprofessional collaboration can enhance the effective integration of PAs into mental health care.

Patient Experience With Primary Care Physician Assistants in Ontario, Canada: Impact of Trust, Knowledge, and Access to Care

Physician assistants (PAs) have been integrated into primary care settings to reduce wait times and to optimize continuity of care. Though previous studies suggest that PA utilization leads to improved healthcare access, few studies have investigated patient experience with primary care PAs in Canada. The objective of this study is to explore patient perspectives on primary care PAs in Ontario. A patient survey was developed and distributed to patients seen by PAs in 4 family medicine practices across Ontario, Canada. Results demonstrate that many patients are highly satisfied with their experience including the PA's ability to address their medical needs, establish rapport, and provide fast access to care (including same-day and after-hours appointments). Despite preferring to see a physician for more complex concerns, participants felt that PAs demonstrate similar medical knowledge, competencies, and scope of practice as family physicians. Patients demonstrated a solid understanding of the PA role and recognized the collaborative PA-physician relationship. These findings describe successful patient awareness and acceptance of the PA profession, largely due to positive PA-patient interactions in family medicine settings.

Physician ratings of physician assistant competencies and their experiences and satisfaction working with physician assistants: Results from the supervising physician survey in Ontario, Canada

Physician Assistants (PAs) are a relatively new addition to the Ontario healthcare system. To understand the impact of the PA role, this study investigated supervising physician satisfaction and perception of PA roles, interprofessional team integration, pandemic supports, and barriers and enablers to PA employment. A web-based survey was conducted of 118 physician supervisors of Ontario PA education program alumni. PAs were employed in a variety of community and hospital settings. In addition to patient care, PAs were involved teaching (65.6%), quality improvement (52.7%), and mentorship (40.0%). Overall, 92.9% of physicians indicated they were satisfied with their PAs. Important barriers to hiring PAs included maintaining PA salaries, billing limitations, and PA shortages. PAs have established themselves as valuable and competent members of healthcare teams. By continuing to explore the enablers and barriers to PA employment from the physician perspective, health leaders can continue to optimize and support role integration.

Where are Canada's PAs in 2023?

ABSTRACT

The physician assistant/associate (PA) role in Canada is slowly expanding from two provinces and 301 PAs in 2012 to five provinces with 959 PAs and 119 clinical assistants in 2022. This article reviews Canadian PA education, healthcare challenges, and future growth, providing a brief look at where in 2023 the 1,215 members of the Canadian Association of Physician Assistants are found, and some anticipated directions.

Application of complexity theory in health and social care research: a scoping review

BACKGROUND

Complexity theory has been chosen by many authors as a suitable lens through which to examine health and social care. Despite its potential value, many empirical investigations apply the theory in a tokenistic manner without engaging with its underlying concepts and underpinnings.

OBJECTIVES

The aim of this scoping review is to synthesise the literature on empirical studies that have centred on the application of complexity theory to understand health and social care provision.

METHODS

This scoping review considered primary research using complexity theory-informed approaches, published in English between 2012 and 2021. Cochrane Database of Systematic Reviews, MEDLINE, CINAHL, EMBASE, Web of Science, PSYCHINFO, the NHS Economic Evaluation Database, and the Health Economic Evaluations Database were searched. In addition, a manual search of the reference lists of relevant articles was conducted. Data extraction was conducted using Covidence software and a data extraction form was created to produce a descriptive summary of the results, addressing the objectives and research question. The review used the revised Arksey and O'Malley framework and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews (PRISMA-ScR).

RESULTS

2021 studies were initially identified with a total of 61 articles included for extraction. Complexity theory in health and social care research is poorly defined and described and was most commonly applied as a theoretical and analytical framework. The full breadth of the health and social care continuum was not represented in the identified articles, with the majority being healthcare focused.

DISCUSSION

Complexity theory is being increasingly embraced in health and care research. The heterogeneity of the literature regarding the application of complexity theory made synthesis challenging. However, this scoping review has synthesised the most recent evidence and contributes to translational systems research by providing guidance for future studies.

CONCLUSION

The study of complex health and care systems necessitates methods of interpreting dynamic prcesses which requires qualitative and longitudinal studies with abductive reasoning. The authors provide guidance on conducting complexity-informed primary research that seeks to promote rigor and transparency in the area.

REGISTRATION

The scoping review protocol was registered at Open Science Framework, and the review protocol was published at BMJ Open (https://bit.ly/3Ex1Inu).

Critical perspectives on rehabilitation education, practice and process: northern Honduras case study

BACKGROUND

Rehabilitation services are an integral part of patient care, but in many developing countries, they are not prioritized and either unavailable or easily accessible to those who need them. Although the need for rehabilitation services is increasing in Honduras, rehabilitation workers are not included in the health care model that guides the care provided to communities, particularly in rural and remote areas. To understand the need for providing impactful rehabilitation services in disadvantaged communities, we explored the education and perception of the community relating to rehabilitation, investigated training available for rehabilitation workers, and examined the rehabilitation processes and practices in Northern Honduras from stakeholders' experiences.

METHODS

We utilized a qualitative descriptive and interpretive approach grounded in case study methodology to understand rehabilitation education, process, and practice in Northern Honduras. Three rehabilitation centres were purposefully selected as the cases, and participants consisted of rehabilitation workers and managers from these centres. We collected data via interviews and focus group sessions. We analyzed the data via thematic analysis using NVivo version 12.

RESULTS

In Northern Honduras, rehabilitation workers' limited training and continuing education, along with awareness about rehabilitation by community members and other health providers influence rehabilitation care. Although policies and initiatives to support people with disabilities and the broader community in need of rehabilitation exist, most policies are not applied in practice. The sustainability of rehabilitation services, which is rooted in charity, is challenged by the small range of funding opportunities strongly affecting rehabilitation care processes and clinical practices. The lack of trust and awareness from the medical profession towards rehabilitation workers sets a major barrier to referrals, interdisciplinary work, and quality of life for individuals in need of rehabilitation.

CONCLUSION

This study advances knowledge of the need to increase understanding of rehabilitation care among community members and health providers, improve care processes and resources, and foster interprofessional practice, to enhance the quality of care and promote equitable care delivery, especially in rural and remote communities.

The impact of care of the elderly certificates of added competence on family physician practice: results from a pan-Canadian multiple case study

Background

Family physicians serve an important role in the care of older adults, and have variable levels of training and comfort navigating this complex patient population. The Care of the Elderly (COE) Certificate of Added Competence offered by The College of Family Physicians of Canada recognizes family physicians with advanced expertise in older adult healthcare. We explored how COE training and certification impacts primary care delivery to older patients, including factors that impact group practice.

Methods

We conducted a secondary analysis of multiple case study data to explore similarities and differences within and across cases. We defined cases as a practice or collective of family physicians working within a defined group of patients in an interconnected community. We analyzed semi-structured interview transcripts (n = 48) from six practice groups of family physicians across Canada using conventional (unconstrained, inductive) content analysis.

Results

We identified similarities and differences in how COE family physicians function within their group practice and the broader healthcare system. In some cases, COE certifications increased patients’ access to geriatric resources by reducing travel and wait times. Some physicians observed minimal changes in their role or group practice after earning the COE designation, including continuing to largely function as a generalist. While family physicians tended to highly value their COE CAC, this designation was differentially recognized by others.

Conclusions

Our findings highlight the impacts and limitations of COE training and certification, including an opportunity for COE family physicians to fill knowledge and practice gaps. As the number of older adults in Canada continues to grow and increasingly rely on primary care services, COE family physicians are uniquely positioned to strengthen the health system’s capacity to deliver specialized geriatric care.

Interprofessional Education - A Mandate for Today's Radiology Curriculum

Interprofessional education (IPE) brings educators and learners from two or more health professions together in a collaborative learning environment, specifically assuring that learners function as a team to provide patient-centered care, with each team member contributing a unique perspective. The Liaison Committee on Medical Education, the Accreditation Council for Graduate Medical Education, and the American Board of Radiology have endorsed interprofessional and team communication as essential core competencies. Radiology educators must understand, include, and optimize IPE in their pedagogy; as a specialty, radiology must innovate more interprofessional experiences for medical students, residents and other allied health professions.

Continuing to enhance the quality of case study methodology in health services research

Case study methodology has grown in popularity within Health Services Research (HSR). However, its use and merit as a methodology are frequently criticized due to its flexible approach and inconsistent application. Nevertheless, case study methodology is well suited to HSR because it can track and examine complex relationships, contexts, and systems as they evolve. Applied appropriately, it can help generate information on how multiple forms of knowledge come together to inform decision-making within healthcare contexts. In this article, we aim to demystify case study methodology by outlining its philosophical underpinnings and three foundational approaches. We provide literature-based guidance to decision-makers, policy-makers, and health leaders on how to engage in and critically appraise case study design. We advocate that researchers work in collaboration with health leaders to detail their research process with an aim of strengthening the validity and integrity of case study for its continued and advanced use in HSR.

The role of the physician associate: an overview

The physician assistant role in healthcare delivery was first introduced during the 1960s in the USA as a solution to doctor shortages, greater population healthcare needs and increasing healthcare provision costs. Since then, many countries worldwide have utilized the successful USA physician assistant model as a benchmark to guide both physician assistant training and the incorporation of the role into their healthcare systems. While the USA retained the title physician assistant, Ireland and the UK use the title physician associate. Physician assistants/associates are trained in the generalist medical model and function under the supervision of a doctor. Tasks relating to the role include the following: taking patient's medical histories, performing examinations, making diagnosis, requesting tests, analysing results and the initiation of treatment. They practice across a broad range of specialities and settings. Physician assistants in the USA and the Netherlands have prescribing privileges. Statutory regulation for physician assistants/associates lays the groundwork for prescribing privileges and such regulation is under consideration by the government in the UK. Studies indicate that doctors and patients are largely satisfied with the contribution of this profession to healthcare services and physician assistants/associates report good job satisfaction.

Physician associate/assistant contributions to cancer diagnosis in primary care: a rapid systematic review

BACKGROUND

Symptom recognition and timely referral in primary care are crucial for the early diagnosis of cancer. Physician assistants or associates (PAs) have been introduced in 18 healthcare systems across the world, with numbers increasing in some cases to address primary care physician shortages. Little is known about their impact on suspected cancer recognition and referral. This review sought to summarise findings from observational studies conducted in high income countries on PAs' competence and performance on processes concerned with the quality of recognition and referral of suspected cancer in primary care.

METHOD

A rapid systematic review of international peer-reviewed literature was performed. Searches were undertaken on OVID, EMBASE, Web of Science, and CINAHL databases (2009-2019). Studies were eligible if they reported on PA skills, processes and outcomes relevant to suspected cancer recognition and referral. Title and abstract screening was followed by full paper review and data extraction. Synthesis of qualitative and quantitative findings was undertaken on three themes: deployment, competence, and performance. Preliminary findings were discussed with an expert advisory group to inform interpretation.

RESULTS

From 883 references, 15 eligible papers were identified, of which 13 were from the USA. Seven studies reported on general clinical processes in primary care that would support cancer diagnosis, most commonly ordering of diagnostic tests (n = 6) and referrals to specialists (n = 4). Fewer papers reported on consultation processes, such as examinations or history taking (n = 3) Six papers considered PAs' competence and performance on cancer screening. PAs performed similarly to primary care physicians on rates of diagnostic tests ordered, referrals and patient outcomes (satisfaction, malpractice, emergency visits). No studies reported on the timeliness of cancer diagnosis.

CONCLUSION

This review of peer-reviewed literature combined with advisory group interpretation suggests the introduction of PAs into primary care may maintain the quality of referrals and diagnostic tests needed to support cancer diagnosis. It also highlights the lack of research on several aspects of PAs' roles, including outcomes of the diagnostic process.
