Systematic Review of Adherence, Compliance and Quality of Life in Type 2 Diabetes Patients. Kumar J 1 B. Pharm. D.M.M, Nair R 2 PhD 1,2 College of Pharmacy, University of Toledo, Toledo, OH, USA . To systematically review the studies that evaluate the quality of life as an outcome of adherence or compliance in type 2 diabetes patients. Diabetes mellitus is one of the most common chronic diseases. In 2007, 246 million people worldwide have diabetes. By 2025, the figure is expected to rise to 380 million. Type 2 diabetes constitute about 85% to 95% of all diabetic cases 1 . In type 2 diabetes, either the body does not produce enough insulin or the cells ignore insulin. Type 2 diabetes leads to serious vascular, nephrologic, neurologic and ophthalmological complications 2 . Non adherence with therapeutic regimens among diabetic patients is a continuing problem 3 . Enhancing adherence to treatment may lead to improved clinical outcomes and reduced number of complications 4 . The patients perception of treatment effectiveness is becoming increasingly important to choose the treatment regimen for chronic diseases such as diabetes. The tools used to measure patients perceptions are quality of life and other patients reported outcomes. When Interventions improve patient perception about their mental and physical health, this improvement enhances patients commitment to self management and their adherence with treatment regimen, which leads to patients’ improved quality of life 5 . Various types of interventions have been studied either to improve treatment adherence or quality of life in diabetes patients. It is important to evaluate change in quality of life due to interventions aimed at improving patients’ adherence. Studies were excluded if they: 1) Measure adherence or quality of life due to use of a different drug treatment 2) Retrospective database studies mentioning adherence were not included . Abbreviations: RCT, Randomized control trials; HbA1C, Glycosylated hemoglobin; I, Intervention group; C, Control group, BMI, Body mass index; GFR, Glomerular filtration rate The main aim of this literature review was to evaluate studies that measure quality of life as an outcome due to intervention used to improve adherence. However, no studies has look quality of life as outcome associated with interventions used to improve adherence/compliance. Table 2: Characteristics of interventions studies that measures quality of life Table 1: Characteristics of Interventions studies that measures adherence The literature search was done by searching the Cochrane library, Ohiolink and Pubmed for articles published between Jan, 2000 and Mar, 2008 to identify interventions containing information on improving adherence and quality of life in type 2 diabetes patients. Search terms included key words, “Diabetes mellitus type 2”, “patient compliance, health education, patient education, physician patient relations” and “Quality of life”.

Background: Objective: Methods Inclusion criteria Results Initial search resulted in 2229 abstracts. Many of these abstract were overlapping as one key search term diabetes mellitus, type 2 was common. After applying the inclusion/exclusion criteria, 8 studies were identified from USA, Korea, Australia, Croatia, Israel and Thailand. The major finding were: References ,[object Object],[object Object],[object Object],[object Object],Conclusion Discussion The authors searched only three databases to identify the relevant articles. The systematic review done on a similar topic by Lindemeyer et al reported that Embase contributed 63.6%, Medline 36.4%, and the Cochrane database 51.5% of relevant articles in their review 6 . The author did not have access to other databases such as Embase at his academic institution. The articles mentioned in this review might not represent the all relevant articles available on the topic. Exclusion criteria Enhanced adherence to treatment recommendation can lead to better clinical outcome and reduced number of complications in type 2 diabetes. The enhanced adherence and improved clinical outcomes can lead to improve quality of life for patients. It is important to measure change in quality of life due to intervention aimed at improving adherence.
