Diabetes care and complications in primary care in the Tshwane district of South Africa.

AIMS

To describe the diabetic population receiving primary care from the Tshwane district public health services and to assess the quality of care of members of this population, their level of disease control and the extent of their complications.

METHODS

A cluster-randomised trial was conducted in 12 primary care clinics in Tshwane district. A total of 599 diabetic patients attending these clinics for review were consecutively interviewed and clinically examined. Data on the care received was also obtained from their clinical records for the previous 12 months. Patients randomised to the active arm of the study were screened for complications.

RESULTS

The mean age was 58 years and 80.5% had a body mass index (BMI) ≥25 kg/m(2). Sixty-eight percent of patients were female. Acceptable glycaemic control and LDL-cholesterol were found for only 27% and 33% of patients, respectively (HbA1c<7%; LDL<2.5 mmol/l). Despite more than 79% of patients reporting to be hypertensive, 68% of patients had a systolic blood pressure above 130 mmHg and 64% had a diastolic blood pressure above 80 mmHg. Evaluating patient records of the preceding year, screening for eye complications was only reported in 8.2%, feet complications in 6.5%, kidney complications in 21.4% and cardiovascular complications in 7.8%. The screening prevalences found were 29% for retinopathy, 22% for maculopathy, 5% for neuropathy (neurothesiometer), 7% for nephropathy (eGFR stages 3-5), 17% for possible infarction (Rose questionnaire) and 36% for severe erectile dysfunction (SHIM questionnaire).

CONCLUSION

Diabetes care and screening for complications at primary care level in the Tshwane district were found to be sub-optimal. Measures should be taken to address this.
