The Established Acute Surgical Unit: A reduction in nighttime appendicectomy without increased morbidity

Area of Science:

• Surgical Outcomes
• Acute Care Models
• Appendicectomy Management

Background:

• Nighttime surgery for non-life-threatening conditions is linked to poorer outcomes.
• Delaying surgery for acute appendicitis can be detrimental.
• The Acute Surgical Unit (ASU) model aims to optimize surgical care delivery.

Purpose of the Study:

• To evaluate the impact of the ASU model on nighttime surgery rates for appendicectomy.
• To assess changes in patient outcomes following the implementation of the ASU model.

Main Methods:

• Retrospective review of medical records for patients undergoing appendicectomy.
• Analysis of primary outcomes including nighttime surgery rate, time to surgery, perforation, complication rates, and length of stay.
• Comparison of data from pre-ASU, early ASU, and established ASU periods.

Main Results:

• Nighttime surgery rates significantly decreased across ASU implementation phases (46.9% to 28.3%).
• Mean time from presentation to surgery increased (14.43 to 18.65 hours), with no significant increase in perforation rates.
• Length of stay significantly decreased between early and established ASU groups (3.1 to 2.8 days).
• No statistically significant increase in complications for nighttime appendicectomies was observed.

Conclusions:

• The ASU model effectively reduced nighttime appendicectomies.
• Implementation of the ASU model did not lead to increased morbidity or length of stay.
• The ASU model demonstrates a safe and efficient approach to managing appendicectomy patients.
