Primary care management of non-institutionalized elderly diabetic patients: The S.AGES cohort - Baseline data

S.AGES is a multicenter prospective cohort study of non-institutionalized patients aged 65 and over with atrial fibrillation, type 2 diabetes or chronic pain. Its objective is to describe the medical management in primary care. This article presents the baseline characteristics of subjects in the diabetes subcohort and compares the results to those from cohorts of older diabetic patients.

From April 2009 to June 2011, 983 patients were included in the diabetes subcohort by 213 primary care providers. Demographic data, geriatric parameters and the history, characteristics and treatment of the diabetes were recorded at baseline.

The mean age was 76.7 ± 5.9 years. Most patients were living independently, with no cognitive impairment and in relatively good health. The duration of diabetes was 11.3 ± 8.7 years with average HbA1c of 6.9 ± 1.0%. 20% of patients had macrovascular disease, 33% renal failure, 14.6% ocular complication and 7.1% neuropathy. The first-line antidiabetic treatment was metformin (61.2%) and 18% of patients had used insulin. Treatment intensified with the worsening of diabetic symptoms. When compared to those from French and North American cohorts, the results showed increased complications and use of insulin with age, disease duration and severity.

Due to the method of recruitment, S.AGES patients were generally healthy with well-controlled diabetes. However, the results were consistent with those from other cohorts. Three-year follow-up is expected to study the management of diabetic patients aged 65 and over in primary care.
