Despite its established efficacy, insulin use remains underutilized. Together with a colleague, Carolina Jo, MD, we conducted a study to determine the prevalence of poor glycemic control among ambulatory type 2 diabetes mellitus patients on insulin, and to evaluate the correlations between insulin dose, diabetes duration, adverse effects, glycemic control and treatment satisfaction based on the Insulin Treatment Satisfaction Questionnaire (ITSQ) score. We performed a one-year cross-sectional study using consecutive sampling technique conducted at the clinics of endocrinologists / diabetologists in a tertiary hospital in the Philippines. Chi-square test was used for categorical data, two-sample independent t-test for continuous data, Pearson's correlation coefficient (r) for correlation, and logistic regression for the prediction of outcome. Computations were made using Epi Infoâ?¢ v7.1.4.0. Among 111 patients, 74.55% had poor glycemic control, 42.34% experienced hypoglycemia episodes and 46.85% gained weight since their last visit. Mean ITSQ score was 77.5 out of 100. Mean frequency of hypoglycemic episodes was 1.9 since last visit, and mean body weight change was +0.15 kg. The occurrence of hypoglycemia and weight gain did not differ between insulin regimens (P= 0.35 and 0.31, respectively). The frequency of daily insulin injections and the dosage of insulin correlated significantly with the frequency of hypoglycemia (r= 0.266, P= 0.004 and r= 0.33, P= 0.0004, respectively). Increased frequency of hypoglycemic episodes was associated with lower treatment satisfaction (r= -0.241, P= 0.01). The frequency of daily insulin injections and ITSQ score were significantly correlated with good glycemic control (OR= 1.933, P= 0.015 and OR= 1.044, P= 0.032, respectively). In conclusion, the prevalence of poor glycemic control among ambulatory type 2 DM patients on insulin in our institution remains high. Treatment satisfaction and frequency of daily insulin injections correlated significantly with good glycemic control. Publications 1. Sandoval MA, Co JM, Lo TE, Berberabe E.
