Summary
Unanticipated admissions after ambulatory surgery occur in 1.42% of patients. Factors like older age, male sex, and longer surgery increase risk, while improved care pathways can reduce these events.
Area of Science:
- Anesthesiology and Perioperative Medicine
- Surgical Outcomes Research
Background:
- Ambulatory surgery offers benefits but carries risks of unplanned hospital admissions.
- Understanding the drivers of these admissions is crucial for improving patient safety and resource allocation.
Purpose of the Study:
- To investigate the incidence, causes, and predictive factors of unanticipated admissions following ambulatory surgery.
- To identify patient and procedural characteristics associated with increased risk of post-discharge admission.
Main Methods:
- Prospective data collection from 15,172 ambulatory surgery patients over 32 months.
- Statistical modeling to identify and classify predictive factors for unanticipated admission.
Main Results:
- Overall incidence of unanticipated admission was 1.42%.
- Predictive factors included older age, male sex, American Society of Anesthesiologists (ASA) status II/III, longer anesthesia duration, late afternoon procedures, and postoperative complications (bleeding, pain, nausea, vomiting, drowsiness).
- Ear, Nose, and Throat (ENT) surgery had the highest admission rate (18.2%), while gynecology had the lowest (0.4%).
Conclusions:
- Targeting earlier operating times for specific procedures may reduce admissions.
- Preoperative screening for adequate home support and proactive management of postoperative issues like pain and nausea are recommended.
- Implementing clinical pathways can mitigate risks and decrease the incidence of unanticipated admissions.
