OBJECTIVES: To analyse the quality of life in insulin-dependent patients and resource consumption due to poor metabolic control after the standarization of glycated hemoglobin measure with A1CNOW+ and the glycemia measure with CONTOUR USB. METHODS: An observational, prospective, multicentre study in patients with diabetes, insulin-dependent, with poor metabolic control has been conducted.  Distribution of the ESDQOL questionnaire which contains the domains satisfaction, impact, social /vocational, concern regarding diabetes and degree of perception of QoL at baseline, at 3 and 6 months. The score of the domains and the full questionnaire is measured on a scale 0-100; where lower scores indicate a higher QoL. Also, Visual Analogic Scale was used to assess the patient's own perception of their quality of life. The resource consumption is analysed for urgent attention due to poor metabolic control, the use of resources included are visits to emergency department, income, length of hospital stay and additional consultations. RESULTS: The evolution of the domains in satisfaction goes from 35.9 at baseline to 31.5 at 6 months. The impact improves from 27.9 at baseline to 26.0 at 6 months, social/vocational concern 25, 8 to 22.4 as well as concerns related to diabetes from 37.7 to 33, 1. Also the degree of perceived improvement in VAS was 2.1 points. All analysed results were statistically significant. At baseline there were 26 patients (7.9%) who required urgent attention due to poor metabolic control in the previous 3 months versus 9 patients (2.8) who requested urgent attention on data collected at 6 months. CONCLUSIONS: CONTOUR USB device to measure glycemia and A1CNow device to measure HbA1C  improve the quality of life of patients and reduce the use of resources due to poor control.
