IntroductionQuality of Life (QoL) is quantitated by assessing physical and social functioning and perceived physical and mental well-being. It is an important health outcome in its own right, representing the ultimate goal of all health interventions. QoL is of particular concern to those patients with chronic diseases. Type 2 diabetes mellitus (T2DM) is a chronic disease and is associated with short-term and long-term complications which can negatively affect patients' well-being, health status and QoL. Compared to persons without diabetes, most studies reported worse QoL for people with diabetes, especially regarding physical functioning and wellbeing.
1,2Diabetes places a significant burden upon health related quality of life (HRQoL), with patients experiencing a reduction in both total and health life years as a result of disability and related comorbidities. Additional challenges arise during the management of diabetes, where the fear of hypoglycaemia, fear of insulin injections and complex treatment regimens are major concerns among patients and have an impact on QoL. The relationship between QoL and diabetes is bidirectional; aspects of diabetes may negatively impact QoL and impaired QoL may also negatively influence diabetes self-management and thus health outcomes and treatment satisfaction (TS).3 Diabetes therapy such as receiving insulin has the potential to affect QoL in both negative and positive ways. Clearly, QoL can be impeded by concerns about needles/pain, hassles of frequent injections, fears and episodes of hypoglycaemia, weight gain, and other potential adverse events. On the other hand, improved glycaemic control can have positive ramifications and also reduce diabetic complications.
AbstractObjectives: To assess the quality of life (QoL) of insulin-naïve people with Type 2 Diabetes Mellitus (T2DM) inadequately controlled on oral antidiabetic drugs (OADs)) after the addition of insulin glargine through the use of self-reported questionnaires (ADDQoL, DTSQs and DTSQc).Design: Insulin-naïve Greek patients with T2DM >1 year inadequately controlled on at least 2 OADs as assessed by HbA1c between 7.0%-9.0% were recruited. The addition of insulin glargine to the treatment was initiated within one month prior to enrollment and patients were evaluated at the beginning of the study and at 3 and 6months through HbA1c measurements and self-reported quality of life questionnaires. Data were analyzed using descriptive statistics.Results: HbA1c (%) ±SD decreased from 8.3±0.5to 7.4±0.7and 7.2±0.6at 3 and 6months, respectively (p<0.001). No significant changes in symptomatic hypoglycemia and no severe hypoglycemia were reported. Concerning the ADDQoL-19, the "present" QoL score improved from 0.42± 0.97 to 0.79±0.81 and 0.93± 0.82 (p<0.001), the "If no Diabete...
