Introduction: The long waiting time for service is a potential problem that always has an impact on patient complaints in several health care facilities. Objective: This study aims to determine the factors related to waiting time for Outpatient Pharmacy services at Hermina Daan Mogot Hospital in 2022. Method: This type of research is quantitative with a cross-sectional study design. Data collection used secondary data obtained for 1 week retrospectively through the PASHMINA application using a form. Result and Discussion: The results showed that 69.3% of the waiting time for pharmaceutical services was inappropriate,60.6% finished drug prescriptions,51.9% <3items and 53.8% used BPJS payment. The results of the Chi square test showed that there was a relationship between the type of prescription (p-value=0.004, PR=1.709), number of drug items (p-value=0.0001, PR=3.023), payment status (p-value 0.0001) and waiting time for pharmaceutical services.
