The impact of co-surgeons on complication rates and healthcare cost in patients undergoing microsurgical breast reconstruction: analysis of 8680 patients.

We identified a total of 8680 patients, out of whom 7531 (87%) underwent MSBR with a SS and 1149 (13%) had a CS. Over the study period, the annual incidence rate of MSBR cases using CS increased from 7.2% in 2010 to 23.3% in 2017 (p < 0.001). Following propensity score matching, complications, emergency room visits, readmissions, and reoperations were all similar between the CS and SS groups. The median total healthcare cost was higher for the CS group [US $76,227 (IQR $67,879) vs. $61,340 (IQR $54,318); p < 0.0001], CONCLUSIONS: Use of the CS approach in MSBR has become increasingly prevalent over time. Analyses of a national claims database suggested that the use of CS is a safe option for patients undergoing MSBR. Further research is needed to optimize CS utilization from a costs and outcomes perspective.
