Abstract
Background
The association between PACU workload periods and prolonged PACU stay remains unclear. This study evaluated the association between different workload periods and prolonged PACU stay after elective surgery under general anesthesia.
Methods
This retrospective cohort study included 16,327 elective surgical patients between February and September 2024. PACU workload periods were categorized into low-activity, routine-activity, subpeak-activity, and peak-activity periods. Prolonged PACU stay was defined as a stay exceeding 2 h. Multivariable logistic regression analysis was performed to identify factors associated with prolonged PACU stay.
Results
The overall incidence of prolonged PACU stay was 4.18%. Compared with the low-activity period, routine-activity (aOR = 2.59, 95% CI: 1.73–3.98), subpeak-activity (aOR = 1.75, 95% CI: 1.20–2.65), and peak-activity periods (aOR = 1.83, 95% CI: 1.27–2.72) were independently associated with prolonged PACU stay (all p < 0.01). Advanced age, comorbidities, surgical complexity, longer operation duration, and greater intraoperative fluid administration were also associated with prolonged PACU stay.
Conclusion
Higher PACU workload periods were independently associated with prolonged PACU stay after general anesthesia. These findings support workload-based optimization of perioperative resource allocation and patient transfer workflow.

Original data from clinical investigations. In particular: Primary research papers from RCTs, observational studies, epidemiological studies; pre-specified sub-analyses; pooled analyses. [Always peer reviewed]
Meta-analyses. [Always peer reviewed]
Systematic reviews. From October 2009, special priority will be given to systematic reviews. [Always peer reviewed]
Non-systematic/narrative reviews. From October 2009, reviews that are not systematic will be considered only if they include a discrete Methods section that must explicitly describe the authors'' approach. Special priority will, however, be given to systematic reviews. [Always peer reviewed]
