A Meta-Analysis to Derive Population-Based Quality Benchmarks of the Incidence of Surgical Site Infection after Lower Limb Revascularization Surgery. Ann Vasc Surg 2024; 104:81-92. [PMID: 37453466 DOI: 10.1016/j.avsg.2023.06.030] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 06/14/2023] [Accepted: 06/21/2023] [Indexed: 07/18/2023]
Abstract
BACKGROUND The reported incidence of surgical site infection (SSI) after lower limb revascularization surgery varies. We conducted a systematic review and meta-analysis of population-based studies reporting the incidence of SSI in adults who underwent these surgeries in high-income countries to derive SSI quality benchmarks. METHODS We searched MEDLINE, EMBASE, CENTRAL, and Evidence-Based Medicine Reviews (inception-to-April 28th, 2022) for population-based studies estimating the cumulative incidence of SSI among adults who underwent lower limb revascularization surgery for peripheral artery disease (PAD) in high-income countries. Two investigators independently screened abstracts and full-text articles, extracted data, and assessed risks of bias. We used random-effects models to pool data and GRADE to assess certainty. RESULTS Among 6,258 citations, we included 53 studies (n = 757,726 patients); 8 of which (n = 435,769 patients) reported nonoverlapping data that were meta-analyzed. The pooled cumulative incidence of any SSI was 6.0 in 100 patients [95% confidence interval (CI) = 4.3-8.0 in 100 patients; n = 8 studies; n = 435,769 patients; moderate certainty]. The cumulative incidence of Szilagyi grade I (cellulitis), grade II (subcutaneous tissue), and grade III (prosthetic graft) SSI was 6.5 in 100 patients (95% CI = 4.3-8.6 in 100 patients; n = 2 studies; n = 39,645 patients; low certainty), 2.1 in 100 patients (95% CI = 2.0-2.3 in 100 patients; n = 2 studies; low certainty), and 0.4 in 100 patients (95% CI = 0.4-0.4 in 100 patients; n = 1 study; n = 333,275 patients; low certainty), respectively. The pooled cumulative incidence of any early (in-hospital/≤30-days) and late (>30-days) SSI was 6.2 in 100 patients (95% CI = 4.4-8.0 in 100 patients; n = 7 studies; n = 431,273 patients; moderate certainty) and 3.7 in 100 patients (95% CI = 2.2-5.2 in 100 patients; n = 2 studies; n = 10,565 patients; low certainty), respectively. CONCLUSIONS This systematic review derived population-based benchmarks of the incidence of any SSI; Szilagyi I, II, and III SSI; and early and late SSI after lower limb revascularization surgery. These may be used by practicing surgeons and healthcare leaders/administrators to guide quality improvement efforts in the United States and perhaps other countries.

The Attributable Mortality of Postoperative Bleeding Exceeds the Attributable Mortality of Postoperative Venous Thromboembolism. Anesth Analg 2021; 132:82-88.

Abstract
BACKGROUND Bleeding and venous thromboembolic disease are considered important sources of postoperative morbidity and mortality. Clinically, treatment of these 2 disorders is often competing. We sought to better understand the relative contributions of bleeding and venous thromboembolic disease to postoperative attributable mortality in a national cohort. METHODS A retrospective analysis of the 2006-2017 American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database was performed to assess the adjusted odds ratio and attributable mortality for postoperative bleeding and venous thromboembolism, adjusted by year. RESULTS After adjustment for confounding variables, bleeding exhibited a high postoperative attributable mortality in every year studied. Venous thromboembolism appeared to contribute minimal attributable mortality. CONCLUSIONS Bleeding complications are a consistent source of attributable mortality in surgical patients, while the contribution of venous thromboembolic disease appears to be minimal in this analysis. Further studies are warranted to better understand the etiology of this disparity.

Trends, factors, and disparities associated with length of stay after lower extremity bypass for tissue loss. J Vasc Surg 2020; 73:190-199. [PMID: 32442606 DOI: 10.1016/j.jvs.2020.04.511] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Accepted: 04/17/2020] [Indexed: 12/13/2022]
Abstract
OBJECTIVE The objective of this study was to determine predictors of increased length of stay (LOS) in patients who underwent lower extremity bypass for tissue loss. METHODS Using 2011 to 2016 National Surgical Quality Improvement Program vascular targeted databases, we compared demographics, comorbidities, procedural characteristics, and 30-day outcomes of patients who had expected LOS vs extended LOS (>75th percentile, 9 days) after nonemergent lower extremity bypass for tissue loss. We also compared factors associated with short LOS (<25th percentile, 4 days) and extended LOS (>75th percentile, 9 days) vs the interquartile range of LOS (4-9 days). Yearly trends and independent predictors were determined by linear and logistic regression. This study was exempt from Institutional Review Board approval. RESULTS In 4964 analyzed patients, there were no significant yearly trends or changes in LOS in the recent 5 years (P > .05). Overall 30-day mortality, major amputation, and reintervention rates were 1.6%, 4.5%, and 4.8%, respectively, also with no significant yearly trends (all P > .05). On univariate analysis, nonwhite race, dependent functional status, transfers, dialysis, congestive heart failure, hypertension, beta blockers, distal bypass targets, and extended operative time were associated with extended LOS (P < .05). Extended LOS was also associated with higher rates of 30-day major adverse limb and cardiac events, additional procedures related to wound care, deep venous thrombosis, complications (pulmonary, renal, septic, bleeding, and wound), and discharge to facility but lower 30-day readmission rates. After adjustment for covariates, the independent factors for extended LOS included dialysis, beta blockers, prolonged operative time, reintervention, major amputation, additional procedures related to wound care, deep venous thrombosis, complications (pulmonary, renal, septic, bleeding, and wound), and discharge to facility (P < .05). On the other hand, multivariable analysis showed that patients with expected LOS were significantly more likely to have been of white race or readmitted postoperatively (P < .05). CONCLUSIONS From 2011 to 2016, there were no significant changes in LOS. Efforts to decrease LOS without increasing readmission rates while focusing on some of the identified factors, including preventable postoperative complications and pre-existing socioeconomic factors, may improve the overall vascular care of these challenging patients.

Abstract
A variety of existing perioperative informatics tools offer clinicians and researchers the opportunity to improve the delivery of care and clinical outcomes for patients undergoing cardiac and vascular surgery. Many of these tools can be used to improve the reliability of the care delivery process through the application of clinical decision support tools and/or quality improvement methodologies at a number of junctures. In this review, the authors will offer a concise overview of the existing perioperative informatics literature, with a focus on tools considered to be of utility in confronting the unique challenges inherent to cardiac and vascular surgery. The authors also highlight areas that they believe are of interest for future targeted inquiry.
