Quantifying and interpreting inequality of surgical site infections among operating rooms.

摘要: The incidence of surgical site infection differs among operating rooms (ORs). However, cost effectiveness interventions targeting ORs depends on counts. purpose this study was to quantify the inequality counts ORs. We performed a single-centre historical cohort elective cases spanning 160-week period from May 2017 2020, identifying within 90 days using International Classification Diseases, Tenth Revision, Clinical Modification diagnosis codes. used Gini index measure infections As reference, for household disposable income in US 0.39, and 0.31 Canada. There were 3,148 (3.67%) 85,744 studied. 20% 57 with most least accounted 44% (99% confidence interval [CI], 36 52) 5% CI, 2 8), respectively. 0.40 0.50), which is comparable US. more minutes (Spearman correlation ρ = 0.68; P < 0.001), but generally not total (ρ 0.11; 0.43). Moderately long (3.3 4.8 hr) had large effect, having greater incidences infection, while being so long as have just one case per day OR. substantially 557 observed combinations OR specialty (Gini 0.85; 99% 0.81 0.88). Inequality substantial caused by both in the cases. due principally to inequality
