Real-World Practices of Pentosan Polysulfate Maculopathy Screening in Various Clinical Settings and Practice-Associated Factors

초록

Objectives: This study investigated the practice patterns of pentosan polysulfate (PPS) maculopathy screening in various clinical settings and demographic and clinical characteristics associated with these screening practices using a health claims database. Methods: In this nationwide population-based study, data from the Health Insurance Review and Assessment database in South Korea were analyzed to identify patients who underwent PPS. The participants were categorized based on whether they had undergone a baseline examination (the first ophthalmic examination since PPS prescription) within one year of PPS use, subsequent monitoring within one year of the baseline examination, or recent monitoring within a 1-year period before the study end date. Demographic and clinical factors were compared between the groups, and factors associated with screening practices were identified using logistic regression analyses. Results: Significant differences in screening practices were observed based on sex, age, residence, the medical specialty of the prescribing physician, indications for PPS use, and hospital type of prescription. Older patients who received PPS prescriptions from urologists were more likely to undergo baseline and monitoring examinations. Logistic regression analyses revealed that older age, female sex, and a longer duration of PPS use were significantly associated with baseline screening. Subsequent and recent monitoring was significantly associated with age, duration of PPS use, and treatment at primary hospitals. Conclusions: This study underscores the variability in screening practices for PPS users based on demographic and clinical factors, emphasizing the need for standardized guidelines. Enhanced awareness and timely referral for maculopathy screening, particularly among non-urological specialties, are essential.
