Abstract: | AimsTo investigate the frequency and predictors (diabetes care and treatment, comorbidity) of documented hypoglycaemia in primary care patients with insulin-treated type 2 diabetes.MethodsData from 32,545 patients (mean age: 70 (SD 11) years, 50.3% males) from 1072 practices were retrospectively analyzed (Disease Analyzer database Germany: 09/2011–08/2012). Logistic regression (≥1 documented hypoglyemia) was used to adjust for confounders (age, sex, practice characteristics, diabetes treatment regimen).ResultsThe prevalence of patients (12 months) with at least one reported hypoglycaemia was 2.2% (95% CI: 2.0–2.4%). The adjusted odds of having hypoglycemia were increased for renal failure (OR; 95% CI: 1.26; 1.16–1.37), autonomic neuropathy (1.34; 1.20–1.49), and adrenocortical insufficiency (3.08; 1.35–7.05). Patients with mental disorders including dementia (1.49; 1.31–1.69), depression (1.24; 1.13–1.35), anxiety (1.18; 1.01–1.37), and affective disorders (1.80; 1.36–2.38) also showed an increased odds of having hypoglycemia. Location of the practice in an urban area was associated with a lower odds ratio (0.74; 0.68–0.80).ConclusionsBoth individual patient characteristics (e.g. comorbidity) and regional factors (practice location) have a substantial impact on hypoglycaemia in primary care patients with insulin therapy. |
