Evaluación de la satisfacción del paciente diabético con la utilización del glucómetro portátil BGSTAR© mediante el cuestionario SATIGLU

Objectives

To assess satisfaction of patients diagnosed with Diabetes Mellitus (DM), type 1 and 2, with use of the portable glucometer BGStar^© using the previously validated SATIGLU questionnaire. The relationships between satisfaction level and adherence to continuous glucose monitoring, insulin therapy, and with the level of glycemic control (% HbA1c), were also studied.

Material and method

Epidemiological, multicenter, cross-sectional study that included 221 diabetic patients aged over 18 years, receiving treatment with insulin and using the BGStar^© glucometer. Socio-demographic and clinical data were collected, as well as treatment and adherence data. Patients self-completed the SATIGLU questionnaire and Morisky-Green (M-G). A descriptive analysis was carried out on the SATIGLU scores and other study variables. An analysis was performed to calculate the association between satisfaction scores and the number of insulin injections and the number of glucose controls (Spearman rho), and with the adherence to treatment classification according to M-G, and with the glycemic control classification according to % HbA1c. Multiple Linear Regression analysis was conducted to identify the variables associated with SATIGLU scores.

Results

Mean age (SD) 57.96 (15.60) years; 56.60% male; 80.82% T2DM; good glycemic control (% HbA1c≤7), 65.30%. Mean (SD) insulin injections/day, 2.35 (1.34), and blood glucose/day controls 2.56 (1.29), with 75.57% showing adherence to therapy (M-G). A positive correlation was found between the SATIGLU and the number of glycemic controls (rho = 0.251; P=.001) and of insulin injections (rho = 0.235; P=.001). SATIGLU scores were higher in adherent patients and in those with better glycemic control (P<.0001). The regression model showed that the variables associated with satisfaction were: adherence (B= 7.006; P<.0001), and the number of glycemic controls (B= 3,214; P=.014).

Conclusions

The patients studied showed high satisfaction with the BGStar^© glucometer, with a high level of adherence to insulin therapy. They also had more insulin injections, a higher number of glycemic controls, and a better DM control.
