A cross-sectional study was conducted to investigate whether glucose control in 20 non-insulin-dependent diabetic subjects seen at a remote rural clinic was comparable to control achieved in 66 diabetic subjects seen at the regional hospital clinic. Sampling was done to assure that study subjects were representative of all care-seeking, diagnosed diabetics in a well-defined Navajo community. The two groups of patients were comparable in terms of age, sex, and duration of diabetes from time of diagnosis. Compliance with care, hospitalization rates, and complication rates were similar in each group. Results showed no significant differences in glycemic control between the rural clinic (mean fasting plasma glucose = 177, mean random plasma glucose = 227) and the regional hospital clinic (mean fasting plasma glucose = 187, mean random plasma glucose = 249). The percentages of diabetics under "acceptable" control by American Diabetes Association guidelines was 40 percent at the rural clinic and 29 percent at the hospital clinic (P greater than .05). The authors conclude that adequacy of glycemic control in diabetics is not compromised by providing care at a remote rural clinic.
