Abstract

Patient adherence is an important component of an efficient therapy. For diabetes patients it may contribute to controlled glucose values and reduction of adverse outcomes. We aim to examine a potential association of Lower Austrian diabetes patients' adherence concerning their disease monitoring and mortality. Using a retrospective cohort study design, claims data of 55,873 diabetes patients were examined for regular HbA1c lab tests that served as a proxy for monitoring related adherence. The cumulative incidence of mortality was estimated in the total study population and separately for different levels of adherence using the product-limit method. Mortality was compared between the different levels of adherence by the log-rank test. The cumulative incidence of mortality after one and two years was 4.2% and 8.7%. Patients with low adherence had a significantly higher risk of mortality than patients with high adherence (p < 0.001). Further results of a multivariable analysis will be presented at the conference. According to our preliminary univariate analysis, monitoring related adherence seems to be substantially beneficial for diabetes patients in Lower Austria.

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
