Compliance with treatment of patients with glaucoma
Introduction: Glaucoma is progressive, chronic optic neuropathy, causing visual field damage and progressive loss of sight. This is a leading cause of preventable blindness and most often asymptomatic disease. Recommended management of glaucoma typically includes the use of medication(s). Compliance rates vary between 25 and 59%. Patient reported outcomes (PRO's) are an umbrella term, covering a broad range of health data reported by patients. PRO's self reported questionnaires are developed to assess several aspects of patient health status, including treatment satisfaction and adherence. Study objective: To assess patient satisfaction with medication effectiveness, medication side effects, convenience and overall treatment satisfaction. Material and method: Using a crosssectional study design, glaucoma patients had been recruited, and examined at the Centre for Sight "Oftalmika" in Belgrade, Serbia in the period between May 15th and June 15th 2011. The questionnaire used in research was the Treatment Satisfaction Questionnaire for Medication Version ii (TSQM). Results: Total of 73 glaucoma patients filled out the Treatment Satisfaction Questionnaire. The mean age was 62.8 years. Satisfaction score for TSQM subscales: Effectiveness, Side Effects, and Convenience and Overall Satisfaction have not showed statistically significant difference between the subscales. The participants are satisfied with the treatment effectiveness, independently on gender, age, level of the education, and the difference within the family life style. Participants from the secondary educational level (iSCED levels) showed significantly lower satisfaction with the side effects than others. Also, there is a significantly higher level of satisfaction with treatment, for the people who live alone. Overall, the study determined that there is a statistically significant positive linear correlation between overall satisfaction with treatment and its determinants. Conclusion: Our respondents showed a high level of satisfaction with therapy. Patients' satisfaction with treatment was higher in patients who believe that the therapy is effective, who are not bothered with the influence of side effects and are satisfied with the therapeutic schemes.
