Characteristics of medical deserts and approaches to mitigate them: a scoping review.

INTRODUCTION: Medical deserts are increasingly considered problematic and many countries employ a multitude of actions and initiatives to achieve a better distribution of the health workforce (HWF). This study systematically maps research and provides an overview of the definitions/characteristics of medical deserts. It also identifies contributing factors and approaches to mitigate medical deserts. METHODS: Embase, MEDLINE, CINAHL, Web of Science Core Collection, Google Scholar and The Cochrane Library were searched from inception to May 2021. Studies reporting primary research on definitions, characteristics, contributing factors and approaches to mitigate medical deserts were included. Two independent reviewers assessed studies for eligibility, extracted data and clustered studies. RESULTS: Two-hundred and forty studies were included (49% Australia/New Zealand, 43% North America, 8% Europe). All used observational designs except for five quasi-experimental studies. Studies provided definitions (n=160), characteristics (n=71), contributing/associated factors (n=113), and approaches to mitigate medical deserts (n=94). Most medical deserts were defined by the density of the population in an area. Contributing/associated factors consisted in sociodemographic/characteristics of HWF (n=70), work-related factors (n=43) and lifestyle conditions (n=34). Approaches focused on training adapted to the scope of rural practice (n=79), HWF distribution (n=3), support and infrastructure (n=6) and innovative models of care (n=7). DISCUSSION: Our study provides the first scoping review on definitions, characteristics, contributing/associated factors and approaches to mitigate medical deserts. We identified gaps such as the scarcity of longitudinal studies to investigate factors contributing to medical deserts, and interventional studies to evaluate the effectiveness of approaches to mitigate medical deserts.

Recruitment and retention of general practitioners in European medical deserts: a systematic review.

INTRODUCTION: Despite policies aiming at universal health coverage by ensuring availability and accessibility of general practitioners (GPs), medically underserved areas are still present in Europe. This systematic review aims to summarize and compare literature on interventions and their potential effectiveness of GP recruitment and retention in these underserved areas ('medical deserts') from 2011 onwards. METHODS: PubMed and Embase were used to identify publications, applying a two-stage selection process. All types of study designs, published in the past 10 years, were included if they discussed a possible intervention for GP recruitment or retention covering an underserved area in an EU-27/EEA/EFTA country (part of the European Union, the European Economic Area or the European Free Trade Association). Exclusion criteria were abstracts or full text not available, conference abstracts, poster presentations, books or overlapping secondary literature. Identified interventions were classified into four categories: 'education', 'professional and personal support', 'financial incentives' and 'regulation'. Eligible articles were critically appraisal by two authors (JB, LF), independently, by using the Joanna Briggs Institute checklist. RESULTS: Of the 294 publications initially retrieved, 25 publications were included. Of them, 14 (56%) described educational interventions, 13 (52%) professional and personal support, and 11 (40%) financial or regulatory interventions. Overlapping categories were often described (56%). The effectiveness of educational or supportive interventions has mainly been evaluated cross-sectionally, whereby causal inference on future GP availability cannot be implied. Few and mixed results were found for the effectiveness of financial and regulatory interventions, because period co-interventions were not taken into account during the study. CONCLUSION: In the past 10 years, educational and supportive interventions to improve GP recruitment and retention have been reported most frequently, but often overlapping strategies are seen. While multiple strategies have potential to be effective, their limited evaluation makes it difficult to provide suggestions for policymakers to adapt their GP recruitment and retention strategies aiming at a best-practice approach in European medical deserts.

Characteristics of Medical Deserts and Approaches to Mitigate Their Health Workforce Issues: A Scoping Review of Empirical Studies in Western Countries.

BACKGROUND: Medical deserts are considered a problematic issue for many Western countries which try to employ multitude of policies and initiatives to achieve a better distribution of their health workforce (HWF). The aim of this study was to systematically map research and provide an overview of definitions, characteristics, contributing factors and approaches to mitigate medical deserts within the European Union (EU)-funded project "ROUTE-HWF" (a Roadmap OUT of mEdical deserts into supportive Health WorkForce initiatives and policies). METHODS: We performed a scoping review to identify knowledge clusters/research gaps in the field of medical deserts focusing on HWF issues. Six databases were searched till June 2021. Studies reporting primary research from Western countries on definitions, characteristics, contributing factors, and approaches were included. Two independent reviewers assessed studies for eligibility, extracted data and clustered studies according to the four defined outcomes. RESULTS: Two-hundred and forty studies were included (n=116, 48% Australia/New Zealand; n=105, 44% North America; n=20, 8% Europe). All used observational designs except for five quasi-experimental studies. Studies provided definitions (n=171, 71%), characteristics (n=95, 40%), contributing factors (n=112, 47%), and approaches to mitigate medical deserts (n=87, 36%). Most medical deserts were defined by the density of the population in an area. Contributing factors to HWF issues in medical deserts consisted in work-related (n=55, 23%) and lifestyle-related factors (n=33, 14%) of the HWF as well as sociodemographic characteristics (n=79, 33%). Approaches to mitigate them focused on training adapted to the scope of rural practice (n=67, 28%), HWF distribution (n=3, 1%), support/infrastructure (n=8, 3%) and innovative models of care (n=7, 3%). CONCLUSION: Our study provides the first scoping review that presents and categorizes definitions, characteristics, contributing factors, and approaches to mitigate HWF issues in medical deserts. We identified gaps such as the scarcity of longitudinal studies to investigate the impact of factors contributing to medical deserts, and interventional studies to evaluate the effectiveness of approaches to mitigate HWF issues.
