N03 Medication adherence in relation to Health-related Quality of Life in patients with Inflammatory Bowel Disease – A cross-sectional study


 
 
 Inflammatory Bowel Diseases are chronic diseases often with complex treatment. The treatment is lifelong and complex and may include several different pharmaceutical groups and sometimes surgery. Not rarely is treatment resistance developed and the treatment may come with different degrees of side effects. Earlier research has shown insufficient to medication adherence and a lower degree of health-related quality of life in patients with inflammatory bowel disease.
 The aim is to describe the relationship between medication adherence and health-related quality of life in a Swedish population diagnosed with inflammatory bowel disease. Additional research questions are if any risk factors of low medication adherence can be identified from the collected variables.
 
 
 
 This cross-sectional study included N=206 patients from three different regions in Sweden. The questionnaires MMAS-8 and Short Health Scale were used combined with a questionnaire regarding patient characteristics. The data and patient characteristics were described and analyzed using descriptive statistics.
 Ethical approval has been received from the Regional Ethical Review Board, Linköping, Sweden (no.: 2015/369-31).
 
 
 
 The majority of patients had Ulcerative Colitis (62.6%) There were no significant differences between the different groups of Inflammatory Bowel Disease regarding patient characteristics apart from having gone through surgical procedures, which were more common in patients with Crohn’s disease. A small correlation was shown between medication adherence and the health-related quality of life dimension social function (rho = -0.146; p <0.05). Medication adherence showed no significant correlations to the remaining health-related quality of life dimensions: disease related worry, symptom burden and sense of general well-being. Possible risk factors identified for low medication adherence were age between 30 and 50, working at high occupational level, and higher educational level.
 
 
 
 The complexity of measuring medication adherence has been established, making it difficult to make any certain conclusions regarding the hypothesis in this report. This study showed no clear association between medication adherence and health-related quality of life in patients with inflammatory bowel disease. However, it visualized the need of optimizing the instruments used to measure medication adherence in individuals with a non-conventional treatment plan
