Comprehensiveness in Primary Care: A Scoping Review

Context: Associated with system efficiency and patient-perceived quality, comprehensiveness is widely recognized as foundational to high-quality primary care. However, there is concern that comprehensiveness is declining and that primary care physicians are providing a narrower range of services. Efforts to address this perceived decline are hampered by the many different and sometimes vague definitions of comprehensiveness in current use. This scoping review explored how comprehensiveness in primary care is conceptualized and defined in order to map its attributes in support of being able to more clearly and precisely define this key concept in research, practice, and policy.

Methods: We conducted a scoping review, following the methods of Arksey and O’Malley and Levac and colleagues. The search included terms for two key concepts: primary care and comprehensiveness. Developed in Ovid Medical Literature Analysis and Retrieval System Online (MEDLINE), the search was adapted for Cumulated Index in Nursing and Allied Health Literature (CINAHL) and Embase, as well as for gray literature. After a multistep review, included sources underwent detailed data extraction.

Findings: A total of 360 sources were extracted; 57% were empirical studies and 65% were published between 2010 and 2022. Across these sources, we identified nine attributes of comprehensiveness in primary care. We mapped these attributes into two conceptual domains: breadth of care (services, settings, health needs and conditions, patients served, and availability) and approach to care (one-stop shop, whole-person care, referrals and coordination, and longitudinal care). Additionally, we identified three enablers of comprehensiveness, namely structures and resources, teams, and competency.

Conclusions: The conceptual map of comprehensiveness in primary care offers a valuable tool that supports clarity for future use of the term comprehensiveness. The domains and attributes we identified can be used to develop definitions and measures that are appropriate to research, practice, and policy contexts, enabling more precise efforts to improve primary care systems.
