AIM: To estimate the overall drug compliance for local Chinese glaucoma patients on long-term topical treatment. METHODS: This was a retrospective cross-sectional study. Fifty-seven primary glaucoma patients from the subspecialty clinic of a publicly-funded tertiary care hospital in Hong Kong completed a questionnaire on compliance with topical glaucoma medication, attitude towards glaucoma and therapy and vision related quality of life. Noncompliance was defined as reporting missing more than or equal to 10% of the prescribed topical glaucoma medication during the 2wk immediately prior to the consultation. Relationships between noncompliance and demographics, attitude, disease and treatment status was studied. Cost was estimated with quality of life and direct medical cost involved with noncompliance. Multivariable logistic regression on noncompliance was performed on selected factors. RESULTS: Compliance was calculated as 75% (95% CI: 64%-87%) among 57 subjects (mean age 69y, female 51%). No statistical significant relationship was established between noncompliance and any single factors or outcomes. Age (P=0.048) and forgetfulness (P=0.064) were found to be marginally significant predictive factors on noncompliance in multivariable logistic regression. Noncompliance might be related (P=0.130) to poorer self-rated vision-associated quality of life. The societal cost of noncompliance was estimated to be over 2510 life-years and US$ 3.7 million territory-wide. CONCLUSION: The compliance of Chinese glaucoma patients in Hong Kong is comparable to other parts in the world, and carries detrimental impacts on individual and societal levels. Age and forgetfulness are two possible independent predictors for noncompliance.
