Summary
Operating room turnover time (TOT) is significantly impacted by the time of day. Early case completion before 1400 and consistent surgical teams are key to improving operating room efficiency and reducing costs.
Area of Science:
- Healthcare Management
- Surgical Operations
- Health Services Research
Background:
- Efficient operating room (OR) management is crucial for healthcare economics.
- Resource allocation directly impacts hospital revenue and expenditure.
- Optimizing OR processes is essential for financial sustainability.
Purpose of the Study:
- To evaluate the impact of surgical, anesthesiology, and nursing team composition on OR turnover time (TOT).
- To determine the influence of the time of day on OR efficiency.
- To identify factors affecting operating room turnover time.
Main Methods:
- Retrospective review of elective surgical cases (July 2017–March 2018).
- Analysis of 2174 cases across 13 specialties at a single academic hospital.
- Multivariate regression to identify predictors of TOT.
Main Results:
- Consistent surgical teams (specialty, surgeon, anesthesiologist) were associated with lower TOT.
- Cases completed before 1400 demonstrated significantly reduced TOT.
- A cutoff time of 1400 showed high sensitivity and specificity for predicting TOT differences.
Conclusions:
- The time of day significantly influences OR turnover time.
- Staffing patterns and scheduling impact OR efficiency.
- Further research is needed to optimize OR operations and reduce costs.

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
