ABSTRACT: Introduction
The primary aim of this analysis was to explore whether glycemic control (glycated hemoglobin [HbA1c] <7%) and the incidence of hypoglycemia are different between Chinese patients with type 2 diabetes mellitus (T2DM) receiving oral antihyperglycemic medication (OAM)-only or insulin-only regimens.Methods
Physicians in nine Chinese cities completed surveys (Adelphi Real World Diabetes Disease Specific Programme) from October 2011 to March 2012. Key information collected included patients' demographic and clinical characteristics, HbA1c levels, and hypoglycemia incidence. Patients receiving OAM-only (n = 1077) or insulin-only (n = 292) regimens for ≥6 months who had most recent HbA1c results available and measured within 3 months of survey completion were included. The primary and secondary outcomes were glycemic control and the incidence of hypoglycemia. Primary (multivariate logistic regression analysis with adjustment for potential confounders) and sensitivity analyses (propensity score matching method) were performed.Results
A higher proportion of patients in the insulin-only group achieved glycemic control than patients in the OAM-only group (41.8% vs 35.9%). Insulin-only treatment was associated with significantly (P = 0.013) better glycemic control than OAM-only treatment (odds ratio [95% confidence interval]: 1.48 [1.09, 2.01]). A higher proportion of patients in the insulin-only group experienced hypoglycemia (overall) than patients in the OAM-only group (33.3% vs 14.4%). Insulin-only treatment was associated with significantly (P < 0.001) increased overall hypoglycemia compared with OAM-only treatment (odds ratio [95% confidence interval]: 2.38 [1.72, 3.29]). Sensitivity analysis results were consistent with the primary analysis results.Conclusions
The results of this analysis provide important real-world information on glycemic control and hypoglycemia in Chinese patients with T2DM, which may be useful for guiding evidenced-based management. Notably, Chinese patients with T2DM receiving OAM-only had poorer glycemic control compared with those receiving insulin-only therapy, although patients receiving OAM-only were less likely to experience hypoglycemic events.
