Key result
The presence of respiratory disease, BMI greater than 40, and increasing age were identified as significant risk factors for unanticipated hospital admission within 48 hours following ambulatory surgery.
Why the study?
Unanticipated admissions after ambulatory surgery affect hospital flow and costs, and identifying preoperative risk factors can help improve patient selection.

What are the risk factors for unanticipated hospital admission following ambulatory surgery?
Odds Ratio: 0.323
p-value: p=0.001
Increasing age, BMI > 40, and respiratory diseases are significant risk factors for unanticipated hospital admission within 48 hours after ambulatory surgery.
May guide ambulatory surgery patient selection; hypothesis-generating and requires prospective validation.
Context: Unanticipated admissions following ambulatory surgery significantly affect hospital admission and operation room flow. Most of the factors responsible for unanticipated admission following ambulatory surgery were preventable. It is, therefore, crucial to improve patient selection criteria and to identify the risk factors for unanticipated admission during preoperative period. These unanticipated admissions have now been considered as quality care indicator and a target to improve healthcare costs. Aims: To assess the reasons and risk factors for unanticipated hospital admission after ambulatory surgery. Settings and Design: Security Forces Hospital, Riyadh, Kingdom of Saudi Arabia. Methods and Materials: In this case-control study, cases who were re-admitted within 48 hours following ambulatory surgery were included. The convenience sampling was used to identify controls. Data including patients' demographics, type of anesthesia and surgery, any intraoperative or postoperative complications, etc., were extracted. Statistical Analysis Used: Descriptive statistics is used to summarize the study variables. Mean and standard deviation were used for quantitative variables. Percentage and frequencies were used for qualitative variables. Univariate and multivariate logistic regressions were used to assess risk factors for unanticipated hospital admission after ambulatory surgery. Results: There were 153 cases and 147 controls in this study. The study found postoperative pain as the most common reason for re-admission after ambulatory surgery followed by bleeding, fever, and asthma exacerbation. Multivariate logistic regression showed age, BMI more than 40, and presence of respiratory disease as risk factors ( P < 0.05). Conclusions: Age, high BMI more than 40, and presence of respiratory disease increase the risk of unanticipated hospital admission after ambulatory surgery.

Alharthi et al. (2022) conducted a case-control in Ambulatory surgery (n=300). Patient risk factors (respiratory disease, BMI > 40, increasing age) vs. Patients without these risk factors was evaluated on Unanticipated hospital admission within 48 hours after ambulatory surgery (OR 0.323, p=0.001). The presence of respiratory disease, BMI greater than 40, and increasing age were identified as significant risk factors for unanticipated hospital admission within 48 hours following ambulatory surgery.
