Prevalence and predictors of delayed clinical diagnosis of Type 2 diabetes: a longitudinal cohort study.

Diagnostic delays are prevalent for both rare diseases and for common conditions such as type 2 diabetes. This retrospective cohort study in Northern California found that 30% of patients with laboratory evidence of new type 2 diabetes experienced at least a 1-year delay before a diabetes diagnosis was added to their chart. The authors suggest automated tools to facilitate earlier diabetes diagnosis and treatment.
