Background: Gastrointestinal (GI) drugs are often co-prescribed with other medications to prevent GI complications. This study aimed to evaluate the prescribing pattern of potentially unnecessary GI drugs in patients with acute cystitis who were prescribed oral antibiotics and investigate the influencing factors affecting this. Methods: We identified female patients ≥20 years with acute cystitis who visited the outpatient clinic and were prescribed oral antibiotics between July and December by analyzing Health Insurance Review and Assessment Service (HIRA)-National Patients Sample (NPS)-2019 data. Patients with no prior history of GI disorders within 180 days prior to acute cystitis, excluding or including the date of diagnosis of acute cystitis, were selected (Group A and B). Multiple logistic regression analysis was performed to estimate the factors affecting the prescription of potentially unnecessary GI drugs. Results: A total of 1,544 in Group A and 552 patients in Group B were included for the final analysis. Potentially unnecessary GI d rugs w ere presc ribed in 1 ,176 p atients in G roup A ( 76.2%) and 231 patients in Group B (41.8%). Third generation cephalosporines and sulfonamides showed the lower odds ratio for prescribing GI drugs than penicillins. Prescribers from Urology clinics showed more than twice odds ratio for the prescription of GI drugs compared to prescribers from internal medicine clinics. Conclusion: The results of this study showed that potentially unnecessary GI drug prescriptions for patients with acute cystitis were high in South Korea. The positive risk factors affecting the prescription of unnecessary GIs were not patient-related factor but healthcare facility and prescriber-related factors.
