The present study utilized the American College of Surgeons National Surgical Quality Improvement (NSQIP) database to investigate patients undergoing aRCR from 2015 to 2021. The NSQIP database is a validated resource for tracking surgical outcomes, with data sourced from over 600 de-identified hospitals across the United States, collected by trained surgical clinical reviewers. Since the database is entirely de-identified, this study is exempt from approval by the University's Institutional Review Board.
Patients undergoing aRCR were identified using Current Procedural Terminology (CPT) code 29827, excluding those under 18 years of age. Additional exclusion criteria included cases missing variables such as age, height, weight, gender, functional status, American Society of Anesthesiologists (ASA) classification, discharge destination, and CHF status.
Analyzed variables included patient demographics, comorbidities, preoperative laboratory values, and 30-day postoperative complications. Demographic variables covered sex, age, BMI, preoperative functional status, ASA classification, smoking status, and steroid usage. Preoperative comorbidities included insulin-dependent diabetes, hypertension requiring medication, chronic obstructive pulmonary disease (COPD), bleeding disorders, and disseminated cancer. The analysis also included various complications occurring within 30 days postoperatively, such as sepsis, septic shock, pneumonia, reintubation, cardiac event (cardiac arrest requiring resuscitation or myocardial infarction), bleeding requiring transfusion, deep vein thrombosis requiring therapy, pulmonary embolism, failure to wean off the ventilator within 48 hours, deep and superficial incisional surgical site infections (SSI), wound dehiscence, readmission, reoperation, non-home discharge, mortality, and length of stay (LOS) > 2 days. A composite variable, "any complication," was created to include any of the mentioned complications occurring within 30 days postoperatively.
A total of 47,601 patients underwent primary aRCR in NSQIP from 2015 to 2021. Of these, 1,039 cases were excluded as follows: 413 for missing height/weight, 1 for uncategorical gender, 548 for missing functional health status before surgery, 68 for missing ASA classification, and 9 for unknown discharge destination. There were 46,562 patients remaining after exclusion criteria: 46,436 patients were included in the no CHF cohort and 126 patients were included in the CHF cohort (Figure I). CHF was defined by NSQIP as the inability of the heart to pump enough blood to meet the metabolic needs of the body or a situation where the heart can do so only at increased ventricular filling pressure. The criteria used to qualify patients with CHF are delineated in Table I.
Statistical analyses were performed using SPSS Software version 26.0. Bivariate logistic regression was utilized to examine differences in demographics and comorbidities between the two groups. To identify independent relationships between CHF and postoperative complications, multivariate logistic regression was conducted, adjusting for significant associations. Results were expressed as odds ratios (OR) with 95% confidence intervals (CI), and statistical significance was determined at P < 0.05.
