Complication and readmission rates stratified by surgeon volume

Surgeon annual hip arthroscopy volume	30-day complication	90-day complication	30-day readmission	90-day readmission	N
<102	11(0.15%)	20(0.28%)	52(0.72%)	161(2.23%)	7204
102–163	5(0.35%)	5(0.35%)	7(0.49%)	20(1.39%)	1440
164–339	2(0.11%)	3(0.17%)	6(0.34%)	15(0.85%)	1766
≥340	1(0.15%)	2(0.29%)	1(0.15%)	4(0.58%)	686
Fisher’s exact test	P = 0.385	P = 0.791	P = 0.102	P<0.001

P-values denote chi-square comparison of rates, with significant differences identified in 90-day readmission rates. Further comparisons identified a significantly higher readmission rate in the group performing less than 102 cases per/year, compared to those performing 164–339 cases/year (P < 0.001) and those performing >340 cases/year (P  = <0.001).
