Key result
Overlapping surgery was not significantly associated with differences in in-hospital mortality (1.9% vs 1.6%; P=.21) or complications, but was associated with increased surgery length.
Why the study?
Overlapping surgery is of concern because of potential adverse outcomes, but its association with mortality, complications, and length of surgery needed evaluation.
Does overlapping surgery increase mortality, complications, and length of surgery in patients undergoing common operations?
Cohort (n=66,430)
Yes
Does overlapping surgery increase mortality, complications, and length of surgery in patients undergoing common operations?
Effect estimate: difference 0.3% (95% CI -0.2% to 0.7%)
Absolute Event Rate: 1.9% vs 1.6%
p-value: p=.21
Overlapping surgery is not associated with increased in-hospital mortality or complications overall, but it increases surgery length and may increase adverse outcomes in high-risk patients.

Should not yet change practice; leaves open questions on high-risk subgroups and efficiency trade-offs.
Sun et al. (2019) conducted a cohort in Patients undergoing total knee or hip arthroplasty, spine surgery, CABG, or craniotomy (n=66,430). Overlapping surgery vs. Nonoverlapping surgery was evaluated on In-hospital mortality (difference 0.3%, 95% CI -0.2% to 0.7%, p=.21). Overlapping surgery was not significantly associated with differences in in-hospital mortality (1.9% vs 1.6%; P=.21) or complications, but was associated with increased surgery length.
