[Quality of care of patients with diabetes mellitus living in a rural area of Germany].
METHODS
In a population based study the quality of diabetes care of insulin-treated diabetic patients aged 16 to 60 years and living in a rural area was studied. The parameters of metabolic control as well as the incidence of acute complications (severe hypoglycemia with the need of glucose or glucagon injection, ketoacidosis with hospital admission) were assessed by examination and with a standardized questionnaire in 81% of the target population (type-1/type-2-diabetic patients: n = 25/33). Also, in all the patients diabetic long-term complications (retinopathy, nephropathy, amputations of the lower extremities) were examined. 76% of the patients with type-1-diabetes and 91% of the patients with type-2-diabetes mellitus completed standardized questionnaires to assess quality of life and treatment satisfaction.


RESULTS
In type-1-diabetic patients HbA1c was 9.38 +/- 1.6%. In type-2-diabetic patients it was 9.53 +/- 1.91%. None of the patients examined was regularly treated by a specialized physician/diabetologist. The goal of metabolic control, a HbA1c value below 7.2%, was reached only by 4% of the patients with type-1-and 12% of the patients with type-2-diabetes mellitus. In multivariate analysis the most important factor associated with HbA1c was in type-1-diabetic patients female sex (R-squared = 0.17, c = 0.38, p = 0.059); in patients with type-2-diabetes mellitus it was the number of insulin injections per day (R-squared = 0.37, c = 0.19, p = 0.0096). All other factors investigated in the model (diabetes duration, insulin dosage/kg body weight, frequency of blood- or urine-glucose self-monitoring/week, body mass index, educational level) showed no significant associations. Quality of life and treatment satisfaction of the patients were good and comparable to other trials.


CONCLUSIONS
Out of other studies there is evidence for better metabolic control in patients regularly treated by specialized physicians/diabetologists and in patients who participated in structured treatment and teaching programs. These features must be the main goals of treatment for all patients with diabetes mellitus.
