CONTEXT: Higher rates of microvascular complications have been reported for minorities. Disparate access to quality health care is a common explanation for ethnic disparities in diabetic complication rates in the US population. Examining an ethnically diverse population with uniform health care coverage may be useful. OBJECTIVE: To assess ethnic disparities in the incidence of diabetic complications within a nonprofit prepaid health care organization. DESIGN AND SETTING: Longitudinal observational study conducted January 1, 1995, through December 31, 1998, at Kaiser Permanente Medical Care Program in northern California. PARTICIPANTS: A total of 62 432 diabetic patients, including Asians (12%), blacks (14%), Latinos (10%), and whites (64%). MAIN OUTCOME MEASURES: Incident myocardial infarction (MI), stroke, congestive heart failure (CHF), and nontraumatic lower extremity amputation (LEA), defined by primary hospitalization discharge diagnosis, procedures, or underlying cause of death; and end-stage renal disease (ESRD), defined as renal insufficiency requiring renal replacement therapy or transplantation for survival or by underlying cause of death. RESULTS: Patterns of ethnic differences were not consistent across complications and frequently persisted despite adjustment for a wide range of demographic, socioeconomic, behavioral, and clinical factors. Adjusted hazard ratios (relative to that of whites) were 0.56, 0.68, and 0.68 for blacks, Asians, and Latinos, respectively (P<.001), for MI; 0.76 and 0.72 for Asians and Latinos, respectively (P<.01), for stroke; 0.70 and 0.61 for Asians and Latinos, respectively (P<.01), for CHF; 0.40 for Asians (P<.001) for LEA; and 2.03, 1.85, and 1.46 for blacks, Asians, and Latinos, respectively (P<.01), for ESRD. There were no statistically significant black-white differences for stroke, CHF, or LEA and no Latino-white differences for LEA. CONCLUSIONS: This study confirms previous reports of elevated incidence of ESRD among ethnic minorities, despite uniform medical care coverage, and provides new evidence that rates of other complications are similar or lower relative to those of whites. The persistence of ethnic disparities after adjustment suggests a possible genetic origin, the contribution of unmeasured environmental factors, or a combination of these factors.

Advanced stages of the diabetic foot syndrome complicated by ischemia and osteomyelitis frequently result in minor amputation, followed by impaired wound healing and higher-level amputation in the context of regular health structures. Even in specialized foot care centers, peripheral arterial occlusive disease and osteomyelitis still represent the greatest challenge in the strife for limb salvage. Whereas the treatment of nonischemic foot lesions has increasingly become a matter of conservative medicine within recent years, for advanced diabetic foot wounds a multidisciplinary treatment policy is essential. A well-coordinated treatment concept aiming at the elimination of the most relevant prognostic factors ischemia and osteomyelitis is required to achieve high limb salvage rates. Surgical revascularization by distal bypass is a crucially important element of this approach. Percutaneous transluminal angioplasty represents a complementary option for short-segment arterial occlusive disease. Foot-sparing minor surgery improves healing time and rates. A specialized diabetologic foot care clinic provides preclinical diagnosis, planning of inpatient procedures, and selection of patients requiring hospitalization for surgical intervention. In addition, it safeguards postinterventional care for wounds with secondary healing and measures of secondary prevention.
