Pinheiro LC, et al. - Given an increased risk of infections, hospitalizations, and mortality among cancer patients with diabetes, researchers sought to characterize diabetes care management patterns among patients with cancer in the year before and, separately, after a cancer diagnosis. Using the Surveillance, Epidemiology, and End Results (SEER) cancer registry linked to Medicare claims data, they assessed data of a total of 32,728 diabetic patients with cancer and 32,728 matched noncancer controls. Following diagnosis, modest, but significantly lower, rates of diabetes care use was reported among patients with cancer vs controls. They observed greater declines in hemoglobin A1c testing, low-density lipoprotein testing, and receipt of all diabetes indicators 12 months before to after diagnosis in patients with cancer. Findings thereby suggest that patients with cancer in the year after diagnosis reported less diabetes care compared with controls.
