Methods used to identify the prevalence of palliative care needs: An integrative review

Early identification of palliative care (PC) needs is crucial to provide appropriate holistic care to patients. The objective of this integrative review is to synthesize the methods used to identify the prevalence of PC needs.

An integrative review search of the Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus with full text, ProQuest, Wiley InterScience, ScienceDirect, Scopus, PubMed, and Web of Science with publications from 2010 to 2020 was carried out in English. Empirical studies examining the methods used to determine the prevalence of PC needs were included. The methods of data extraction of the included articles were categorized by data source, study setting, and data collector. Quality appraisal was performed using QualSyst.

Of the 5,410 articles screened, 29 were included in this review. Two articles identified the prevalence of PC needs in a community that was supported by a network of volunteers, while 27 studies considered this at a continent, country, hospital, and/or primary care facility level as represented by physicians, nurses, and researchers.

Various methods have been used to determine the prevalence of PC needs, and the outcomes are valuable for policymakers in developing PC services when allocating resources at the national and community levels. Future research to identify PC needs across health settings, especially primary care facilities, should consider providing PC across a spectrum of care settings.
