Background Day surgery, also known as same-day surgery, involves admitting and discharging patients on the same day, aiming to reduce hospital stays. However, various factors can necessitate unplanned inpatient admission. This study assessed admission rates following day surgery and evaluated the causes and associated risk factors, including patient characteristics, type of anesthesia, type of surgery, and time of arrival at the day surgery unit, at Buraidah Central Hospital, Qassim, Saudi Arabia. Methods A retrospective cohort study was conducted in Buraidah Central Hospital, Qassim, Saudi Arabia, using medical records of patients who underwent day surgery between January 2022 and December 2023. Data on demographics, cause of admission, comorbidities, surgery type, anesthesia, and arrival time at the day surgery unit were analyzed. Results Of 3,806 patients who underwent day surgery during the study period, 293 (7.6%) were converted to inpatient care. Most admitted patients were aged 18-59 years, men, and overweight. The primary reasons for admission were the need for further observation and close monitoring. Laparoscopic cholecystectomy was the most common procedure, followed by adenotonsillectomy. Women undergoing laparoscopic cholecystectomy had a higher conversion rate than men. Adenotonsillectomy was more common among patients admitted due to complications. Conclusion The conversion rate from day surgery to inpatient care was 7.6%, higher than the rates reported in other hospitals. This may be linked to the high prevalence of laparoscopic cholecystectomy, which had an 18.3% local conversion rate. General anesthesia was associated with higher conversion rates. No intensive care unit (ICU) admissions were recorded, suggesting severe complications were rare despite the conversions.
