Brazilian multicenter study for the evaluation of patients' satisfaction of blood glucose self-monitoring with BGStar® blood glucose meter in insulinized patients with diabetes mellitus type 1 and 2. Issue 1 (December 2016) - Hissa, Miguel
Abstract Background Diabetes mellitus (DM) is considered a global epidemic, and patient self-management education and support are critical in preventing and reducing the risk of complications. Self-monitoring of blood glucose (SMBG) is essential for care of individuals with DM, helping patients to achieve and maintain target blood glucose levels. The purpose of this study is to compare the satisfaction of insulinized DM patients on SMBG with use of investigational blood glucose meter (BGM) versus their routine device. Methods A national, multicenter, open-label, phase 4 study was conducted on patients with type 1 or 2 DM under insulin therapy regimen, who were asked to use investigational BGM instead of their usual BGM device. The study was performed in 12 centers in Brazil for 12 weeks, with an extension period of 12 weeks. The primary endpoint was to measure the variation on the patients' level of satisfaction with investigational versus routine BGM, between visits, using a Visual Analogue Scale (VAS). Secondary endpoints addressed handling aspects, satisfaction, adherence and level of functionality and safety of investigational BGM. Results The study included 292 patients (36.6 % DM1 and 63.4 % DM2), mean age 50.9 years old (±17.3 years), 57.5 % females. There was statistically significant improvement in global satisfaction with investigational BGM compared with routine BGM according to VAS [mean VAS score raised from 78.8 mm (SD = 18.0) to 90.8 mm (SD = 12.2) between visits]. After 12 weeks, level of satisfaction with investigational BGM according to questionnaires was superior to routine BGM regardless of age group (p < 0.001), type of DM (p < 0.001) or insulin regimen (p < 0.001). Investigational BGM was also regarded as safe, with 10 patients (3.4 %) reporting a total of 13 adverse events during the study. Conclusions Levels of satisfaction during SMBG were higher with use of investigational BGM and the device was deemed safe and easy to handle.
