Laparoscopic Appendectomy and Cholecystectomy Timing Predicts Hand-Offs but Not Miscounts

Intraoperative hand-offs are poorly coordinated and associated with risk of surgical miscount. We evaluated hand-off patterns for nursing staff during two common operations hypothesizing that hand-off patterns would be associated with increased surgical miscounts and vary during operations performed standard versus nonstandard operating hours.

We retrospectively analyzed laparoscopic cholecystectomy (N = 3888) and appendectomy (N = 1768) from 2012 to 2021 at a single institution using electronic medical records. We evaluated intraoperative hand-off patterns and the presence of miscounts for operations performed during standard versus nonstandard hours. Standard operating hours were defined as M-F 7:30 am to 5:00 pm.

Across 5656 operations, 10 cases had surgical miscounts and were significantly longer than those without (156.5 versus 101 min P = 0.0178). More than half (51.3%) of cases had no identified hand-offs, and 42.9% of cases occurred during nonstandard hours. Cases during standard versus nonstandard hours were more likely to have hand-offs (56.0% versus 38.9%), P < 0.0001 and had shorter interval between hand-offs (64 versus 75 min), P < 0.0001. The period between patient entry to the room and intubation, which includes initial counts, had a disproportionately high percentage of hand-offs (P < 0.0001).

Variability in hand-off occurrence and frequency in operations performed during standard and nonstandard hours suggest that hand-offs are influenced by staffing patterns. Few surgical miscounts occurred but were associated with longer cases. Hand-offs disproportionately occurred between patient entry and intubation, with a potential for disruption of initial instrument counts. Future work optimizing hand-off coordination is an opportunity to mitigate risk to patients.
