Objective:
to analyze the factors that influence turnover time in the operating rooms of an oncological hospital.
Method:
a cross-sectional, retrospective study with a sample of 2,929 surgeries performed between February and November 2023 in the surgical center of a philanthropic oncological hospital in northern Paraná. Data were collected from reports completed simultaneously by the circulating nurse during surgeries, recording times for turnover time calculation. Statistical analysis used correlation and variance tests (p<0.05).
Results:
minor surgeries had lower turnover time (median 35 minutes, IQR 27-55 minutes) compared to major surgeries (median 40 minutes, IQR 34.25-64.75 minutes; p<0.001). Positive correlations with higher turnover time were observed in the intervals from patient entry into the operating room to start of anesthesia (r=0.11, p<0.001), anesthesia to incision (r=0.17, p<0.001), and incision to surgical closure (r=0.18, p<0.001). Main reasons for delays were surgeons in other rooms (n=281; 25%), afternoon starts (n=161; 14%), and nursing delays (n=128; 11%).
Conclusion:
minor surgical procedures, surgeons in others operating rooms, and nursing delays influence turnover time. The positive correlations highlight the interdependence of operative processes.
