This study evaluates an employer-based diabetes/prediabetes screening intervention that invited at-risk employees via letters, secure e-mails, and automated voice messages to complete blood glucose testing at a health plan facility.
Quasi-experimental cohort study among health plan members insured by two employers that received the intervention and three employers that were selected as control sites.
The proportion of at-risk members that completed a screening was higher in the intervention group than in the control group (36% vs 13%, P < 0.001, adjusted for patient characteristics). Among those screened in the intervention group, the presence of obesity, hypertension, hyperlipidemia, and tobacco use were significant predictors of having a result that indicated diabetes or prediabetes (P < 0.05, all comparisons).
A low-intensity, employer-based intervention conducted in collaboration with a health care delivery system effectively increased screening for diabetes/prediabetes.
