Area of Science:

Healthcare Management
Surgical Operations
Patient Flow Optimization

Background:

Efficient operating room utilization is crucial for hospital cost-benefit and reducing patient wait times.
A non-commissioned "Twilight" operating room concept was introduced to address elective surgery backlogs and mitigate capacity issues.
Closure of an affiliated hospital operating suite necessitated alternative solutions for elective operative time.

Purpose of the Study:

To evaluate the feasibility and impact of an after-hours "Twilight" operating room on reducing elective surgery waiting lists.
To assess the safety and effectiveness of extended operating room hours for elective procedures.
To provide a strategy for restoring surgical activity impacted by external factors like the COVID-19 pandemic.

Main Methods:

A retrospective audit of a 10-month period was conducted following the implementation of the "Twilight" operating room.
Included in the analysis were patients from 13 non-commissioned Saturday operative sessions.
Data collected focused on surgical procedures performed and patient outcomes.

Main Results:

A total of 223 surgical procedures were successfully completed within the study timeframe.
The majority of patients undergoing procedures were classified as American Society of Anaesthesiologists (ASA) Class 2.
Procedures spanned multiple subspecialties including General Surgery, Orthopaedics, Gynaecology, Urology, Plastic Surgery, and Dental Surgery, with no major complications reported.

Conclusions:

The "Twilight" operating room model proved feasible for conducting elective surgeries outside standard hours.
This approach significantly reduced the hospital's elective surgery waiting time.
No major post-operative complications were observed, indicating a safe and effective strategy for enhancing surgical capacity.
