Adherence to the American Diabetes Association retinal screening guidelines for population with diabetes in the United States
Abstract
Purpose (1) To assess long-term adherence to American Diabetes Association guideline-recommended retinal screening among population with diabetes in the United States. (2) To determine factors associated with long-term adherence to routine eye screening exams. Methods A retrospective cohort study was conducted in adult patients with diabetes identified from January 2009 to December 2010. Patients were followed until disenrollment, death, or study end date (December 2013). A patient was defined as adherent when having at least one exam in each 12-month period if there was evidence of retinopathy, or at least one exam in each 24-month period if there was no evidence of retinopathy. Multivariate logistic regressions were used to investigate patient demographics and other baseline characteristics associated with adherence to guidelines. Results A total of 204,073 patients were identified; the mean age (SD) was 61 (13) years and 48% were female. Overall, 71.1% were adherent to the retinal screening guidelines during a median of 4.8 years of follow-up including 27.7% who received an eye exam every year. Patient socioeconomic status (younger age, black race, lower income/education), less comorbidity, insulin use, higher specialist copayment plans, and proxies for poor patient behavior (lower adherence to the oral hypoglycemic agents, less diabetes education, hemoglobin A1C >9%) were associated with nonadherence to routine eye screening exams. Conclusion During nearly 5 years of foll…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
