Diabetes in the context of incarceration: A scoping review

The burden of chronic conditions, like diabetes, is disproportionately carried by people facing social disadvantages (e.g., those with experiences of incarceration). A dearth of knowledge remains about this topic. We conducted a scoping review to determine the extent of literature about diabetes management and/or self-management in relation to incarceration.

We used the Arksey and O'Malley five stage process, recommendations by Levac et al., and the PRISMA Extension for Scoping Reviews Checklist. Core search terms for diabetes were combined using the Boolean operator AND with terms relevant to incarceration. We initially searched the following electronic academic databases on January 5, 2021, and then updated these searches on September 7, 2022: APA PsycInfo, CINAHL, Criminal Justice Abstracts, EMBASE, MEDLINE, Scopus, and SocINDEX. There were no restrictions on language, study design, quality, location, time, and sex or gender differences. We searched for research articles, conference proceedings, dissertations and theses, government documents, and organization documents. We then searched for other forms of literature using an electronic database (ProQuest Dissertations and Theses - Global), the internet search engine Google, and various corrections and diabetes websites in August 2021 and then updated these searches in September 2022. We also reviewed the reference lists of the final selected documents to identify additional literature.

The search from the seven databases identified 3076 records. The search from other sources (e.g., websites) identified an additional 1077 records. A total of 40 documents met our final inclusion criteria and were included in this review. The type of research conducted was primarily quantitative in nature. Clinic and education interventions were most commonly investigated. Clinical outcomes were often reported. Most guidelines were targeted at healthcare providers. Much of the literature originated from high-income countries, which may not be fully applicable for different contexts like low-income countries. Many interventions were associated with improved outcomes.

Administrators can use our findings to develop appropriate policies for this population. Tailored diabetes education for this population and healthcare providers may improve management practices. Our findings offer key insights for improving diabetes care and outcomes for this underserved population. Addressing the diabetes-specific health needs of these people may improve overall public health.
