Diabetes Prevention in a U.S. Healthcare System: A Portrait of Missed Opportunities

Abstract

Introduction: Type 2 diabetes is a widespread, preventable illness. The U.S. Preventive Services Task Force (USPSTF) has screening guidelines for diabetes prevention. The aim is to establish the extent to which U.S. Preventive Services Task Force's guidelines for prediabetes screening, diagnosis, and treatment are followed in a large health system and to identify missed opportunities for diabetes prevention.

Methods: A comprehensive analysis of the electronic health records for the entire patient population of a large health center between August 1, 2019 and October 31, 2020 was analyzed, focusing on 21,448 patients eligible for prediabetes screening according to USPSTF recommendations. Compliance with U.S. Preventive Services Task Force recommendations for screening, diagnosis, and treatment was assessed.

Results: Of the 21,448 patients identified as eligible for prediabetes screening, 13,465 (62.8%) were screened in accordance with the USPSTF recommendations. Of those patients screened, 3,430 met the requirements for a prediabetes diagnosis. Only 185 (5.4%) of patients who screened positive for prediabetes received a formal diagnosis of prediabetes, and no patients who received a diagnosis received appropriate treatment for their prediabetes. Women were more likely than men to be screened (p<0.001), and non-Hispanic Whites were less likely than non-Hispanic Blacks and Hispanics to be formally diagnosed even after screening positive (p<0.001).

Conclusions: Although a majority of eligible patients receive appropriate screening for prediabetes, diagnosis and treatment of patients who screen positive for prediabetes is not common practice. Future research and policy may benefit from a focus on classifying diabetes prevention as a quality metric and incentivizing behaviors consistent with diabetes prevention.
