Purpose: To explore whether patients with diabetes mellitus (DM) who met Comprehensive Diabetes Care Healthcare Effectiveness Data and Information Set (HEDIS) metrics had a reduced likelihood of experiencing unplanned emergency department (ED) visits, hospitalizations, or mortality. Introduction: The prevalence of DM among U.S. adults is approximately 15% and continues to rise. To enhance care for individuals with DM, Comprehensive Diabetes Care HEDIS quality measures have been established. These measures encompass criteria such as blood pressure control, hemoglobin A1c (HbA1c) levels, and the completion of an annual eye examination. However, the connection of these metrics to health outcomes remains insufficiently studied. Methods: This study comprised a retrospective, cross-sectional exploratory analysis of established patients aged 18 years or older with DM receiving primary care within a suburban integrated delivery network (IDN). Multivariate logistic regression was used to analyze patient characteristics, including demographics, sociomedical factors, and biometrics. Outcome variables encompassed one or more unplanned ED visits (including urgent care), one or more unplanned hospitalizations, or mortality within the one-year study period. Results: Out of 28,929 patients with DM, 5293 (18.3%) had ≥1 ED visit, 3725 (12.9%) had ≥1 hospital admission, and 614 (2.1%) died during 2022. After controlling for available demographic and sociomedical factors, patients with poor HbA1c control (considered HbA1c > 9.0) in the year prior were more likely to experience an ED visit in the study year (adjusted odds ratio [aOR] = 1.292, 95% CI, 1.121-1.489, p < 0.001). Patients who achieved HbA1c control (considered HbA1c < 8.0) in the year prior were less likely to experience an ED visit (aOR = 0.845, 95% CI, 0.763-0.936, p = 0.001) and less likely to experience a hospitalization in the study year (aOR = 0.878, 95% CI, 0.779-0.989, p = 0.032). Patients who completed an eye exam in the year prior were less likely to experience a hospitalization (aOR = 0.913, 95% CI, 0.847-0.984, p = 0.017) or die (aOR = 0.694, 95% CI, 0.579-0.831, p < 0.001) in the study year. Finally, patients who completed microalbumin testing in the year prior were less likely to experience an ED visit (aOR = 0.902, 95% CI, 0.84-0.968, p = 0.004), or die (aOR = 0.464, 95% CI, 0.389-0.554, p < 0.001). Conclusion: Achieving HbA1c control in the previous year is linked to decreased likelihood of experiencing an unplanned ED visit or hospitalization. An eye exam in the year prior was associated with decreased likelihood of hospitalization or death. Further research into interventions aimed at enhancing DM management and reducing associated complications may have potential to enhance patient health outcomes while reducing health care costs.
