While public hospitals provide significant amounts of inpatient, outpatient, emergent, and supportive services to patients, little is known about the care of patients with diabetes across public hospitals, or the extent to which disparities in diabetes outcomes exist within these systems.

In 2002-3, the National Public Health and Hospital Institute assembled a quality improvement consortium involving 7 public hospital systems that provide care to over 125,000 patients with diabetes on an annual basis. We obtained demographic, clinical, and utilization data over a 3-year period on a random sample of 3,000 patients with diabetes from each system. Using patients' last HbA1c value, we measured the proportion of patients with poor glycemic control and explored whether glycemic control varied by race/ethnicity, insurance status, or use of outpatient services. Overall, 69% of patients were non-White minorities, and 42% were uninsured.

Overall, 26% of patients had poor glycemic control. Poor glycemic control was more common among Blacks (29%) and Hispanics (31%) than Whites (19%) or Asians (16%) (P<.001) and was greater among the uninsured (33%) than those with Medicaid (24%), commercial insurance (24%) or Medicare (17%) (P<.001). Adjusting for age, sex, race/ethnicity, insurance, and outpatient utilization, Blacks and Hispanics had worse glycemic control (8.3% and 8.2%) than Whites or Asians (7.8% and 7.9%), as did the uninsured (8.2%) compared to Medicaid (8.0%), commercially insured (7.9%) and Medicare (7.5%) (P<.001).

Despite limited resources and the challenges posed by caring for diverse and vulnerable populations, public hospital systems perform at a level comparable to other health systems with regard to glycemic control. Our results suggest that public hospital systems should target access for the uninsured, continuity of care for all patients, and quality of care for minority populations.
