Extracranial-Intracranial Bypass Surgery: Impact of Caseload

Extracranial-Intracranial Bypass Surgery: Impact of Caseload Impact of Hospital Caseload and Elective admission on Outcomes Following Extracranial-Intracranial Bypass Surgery Abstract Background Limited information exists evaluating the impact of hospital caseload and elective admission on outcomes following patients undergoing extracranial-intracranial (ECIC) bypass surgery. Using the Nationwide Inpatient Sample (NIS) for the years 2001 through 2014, we evaluated the impact of hospital caseload and elective admission on outcomes following bypass. Methods In an observational cohort study, weighted estimates were used to investigate the association of hospital caseload and elective admission on short-term outcomes following bypass surgery using multivariable regression techniques. Results Overall 10,679 patients (mean age: 43.39Â ±19.63 years; 59% female) underwent bypass across 495 non-federal US hospitals. In multivariable models, we noted patients undergoing bypass at high volume centers were associated with decreased probability of mortality(OR:0.39;95% CI:0.22-0.70;p
