Enhancing Type 2 Diabetes Management Involving Healthcare Professionals in Primary Care

Background: Current evidence on diabetes care interventions is either fragmented or focused on specific interventions targeting healthcare professionals or patients. This study aims to categorize diabetes care interventions involving physicians or nurses and their impact on health outcomes for individuals with diabetes. Additionally, it aimed to determine the proportion of favorable findings across healthcare intervention categories. Methods: This scoping review was conducted in primary care settings and guided by a health system framework. We searched articles from inception to June 2022 in databases including CENTRAL, MEDLINE, Embase, PsycINFO, and CINAHL. The classification of healthcare interventions was guided by the Cochrane Effective Practice and Organization of Care taxonomy and health system framework. Results: Results were reported following the PRISMA Extension for Scoping Reviews. From the initial pool of 13,406 articles, 116 met the eligibility criteria and reported interventions conducted across 119 countries or regions, of which 94 were high-level economies. Five healthcare intervention categories were identified: transforming the workforce; service content; re-designing the service delivery system; information and communication technology; and multifaceted. Patient health outcomes were classified into 3 overarching categories with 11 subcategories: clinical outcomes, behavioral outcomes, and psychosocial outcomes. The proportion of statistically significant favorable findings differed across intervention categories and outcome domains. Multifaceted interventions showed relatively higher proportions of favorable findings for clinical outcomes, whereas re-designing the service delivery system interventions showed relatively higher proportions for behavioral outcomes. ICT interventions frequently reported favorable findings related to blood glucose indicators. Conclusions: This study provides a comprehensive overview of healthcare interventions and health outcomes for diabetes in primary care settings. It emphasizes the importance of tailored interventions, delivery methods, and technology integration for effective diabetes management, advocating for a comprehensive approach from individual to societal levels.
