Abstract
Purpose We aimed to investigate the impact of enhanced in-hospital infection prevention during the coronavirus disease 2019 (COVID-19) pandemic on postoperative pneumonia in older surgical patients. Patients and Methods We retrospectively reviewed the electronic medical records of consecutive patients ≥70 years who underwent elective surgery between 2017 and 2021 at our institution. All perioperative variables were retrieved from the electronic medical records. The primary outcome was new-onset postoperative pneumonia during the hospitalization period. Since February 2020, our institution implemented a series of policies to enhance infection prevention, hence patients were divided into groups according to whether they underwent surgery before or during the COVID-19 pandemic. An interrupted time series analysis was performed to evaluate the difference between pre- and post-intervention slopes of the primary outcome. Results Among the 29,387 patients included in the study, 10,547 patients underwent surgery during the COVID-19 pandemic. Although there was a decreasing trend of the monthly incidence rate of postoperative pneumonia compared to before the COVID-19 pandemic, there was no statistical significance in the trend (slope before COVID-19 period: β-coefficient, -0.007; 95% CI, -0.022 to 0.007). Conclusion Our study revealed that enhanced in-hospital infection prevention implemented to manage the COVID-19 pandemic did not significantly affect the decreasing trend of postoperative pneumonia at our institution.

Postoperative Supplemental Oxygen in Liver Transplantation (PSOLT) does not reduce the rate of infections: results of a randomized controlled trial. BMC Med 2023; 21:51. [PMID: 36782227 PMCID: PMC9924861 DOI: 10.1186/s12916-023-02741-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2022] [Accepted: 01/18/2023] [Indexed: 02/15/2023] Open
Abstract
BACKGROUND Despite inconsistent evidence, international guidelines underline the importance of perioperative hyperoxygenation in prevention of postoperative infections. Further, data on safety and efficacy of this method in liver transplant setting are lacking. The aim was to evaluate efficacy and safety of postoperative hyperoxygenation in prophylaxis of infections after liver transplantation. METHODS In this randomized controlled trial, patients undergoing liver transplantation were randomly assigned to either 28% or 80% fraction of inspired oxygen (FiO2) for 6 postoperative hours. Infections occurring during 30-day post-transplant period were the primary outcome measure. Secondary outcome measures included 90-day mortality, 90-day severe morbidity, 30-day pulmonary complications, durations of hospital and intensive care unit stay, and 5-day postoperative bilirubin concentration, alanine and aspartate transaminase activity, and international normalized ratio (INR) (clinicatrials.gov NCT02857855). RESULTS A total of 193 patients were included and randomized to 28% (n = 99) and 80% (n = 94) FiO2. With similar patient, operative, and donor characteristics in both groups, infections occurred in 34.0% (32/94) of patients assigned to 80% FiO2 as compared to 23.2% (23/99) of patients assigned to 28% FiO2 (p = 0.112). Patients randomized to 80% FiO2 more frequently developed severe complications (p = 0.035), stayed longer in the intensive care unit (p = 0.033), and had higher bilirubin concentration over first 5 post-transplant days (p = 0.043). No significant differences were found regarding mortality, duration of hospital stay, pulmonary complications, and 5-day aspartate and alanine transaminase activity and INR. CONCLUSIONS Postoperative hyperoxygenation should not be used for prophylaxis of infections after liver transplantation due to the lack of efficacy. TRIAL REGISTRATION ClinicalTrials.gov NCT02857855. Registered 7 July 2016.

Abstract
OBJECTIVE To compare the early results of mass and layered closure of upper abdominal transverse incisions. SUMMARY OF BACKGROUND DATA Contrary to midline incisions, data on closure of transverse abdominal incisions are lacking. METHODS This is the first analysis of a randomized controlled trial primarily designed to compare mass with layered closure of transverse incisions with respect to incisional hernias. Patients undergoing laparotomy through upper abdominal transverse incisions were randomized to either mass or layered closure with continuous sutures. Incisional surgical site infection (incisional-SSI) was the primary end-point. Secondary end-points comprised suture-to-wound length ratio (SWLR), closure duration, and fascial dehiscence (clinicatrials.gov NCT03561727). RESULTS A total of 268 patients were randomized to either mass (n=134) or layered (n=134) closure. Incisional-SSIs occurred in 24 (17.9%) and 8 (6.0%) patients after mass and layered closure, respectively (P =0.004), with crude odds ratio (OR) of 0.29 [95% confidence interval (95% CI) 0.13-0.67; P =0.004]. Layered technique was independently associated with fewer incisional-SSIs (OR: 0.29; 95% CI 0.12-0.69; P =0.005). The number needed to treat, absolute, and relative risk reduction for layered technique in reducing incisional-SSIs were 8.4 patients, 11.9%, and 66.5%, respectively. Dehiscence occurred in one (0.8%) patient after layered closure and in two (1.5%) patients after mass closure (P >0.999). Median SWLR were 8.1 and 5.6 (P <0.001) with median closure times of 27.5 and 25.0 minutes (P =0.044) for layered and mass closures, respectively. CONCLUSIONS Layered closure of upper abdominal transverse incisions should be preferred due to lower risk of incisional-SSIs and higher SWLR, despite clinically irrelevant longer duration.

Evaluation of the costing methodology of published studies estimating costs of surgical site infections: A systematic review. Infect Control Hosp Epidemiol 2021; 43:898-914. [PMID: 34551830 DOI: 10.1017/ice.2021.381] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Surgical site infections (SSIs) are associated with increased length of hospitalization and costs. Epidemiologists and infection control practitioners, who are in charge of implementing infection control measures, have to assess the quality and relevance of the published SSI cost estimates before using them to support their decisions. In this review, we aimed to determine the distribution and trend of analytical methodologies used to estimate cost of SSIs, to evaluate the quality of costing methods and the transparency of cost estimates, and to assess whether researchers were more inclined to use transferable studies. METHODS We searched MEDLINE to identify published studies that estimated costs of SSIs from 2007 to March 2021, determined the analytical methodologies, and evaluated transferability of studies based on 2 evaluation axes. We compared the number of citations by transferability axes. RESULTS We included 70 studies in our review. Matching and regression analysis represented 83% of analytical methodologies used without change over time. Most studies adopted a hospital perspective, included inpatient costs, and excluded postdischarge costs (borne by patients, caregivers, and community health services). Few studies had high transferability. Studies with high transferability levels were more likely to be cited. CONCLUSIONS Most of the studies used methodologies that control for confounding factors to minimize bias. After the article by Fukuda et al, there was no significant improvement in the transferability of published studies; however, transferable studies became more likely to be cited, indicating increased awareness about fundamentals in costing methodologies.

Ann Thorac Surg 2021; 113:1274-1281. [PMID: 33882292 DOI: 10.1016/j.athoracsur.2021.04.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 03/01/2021] [Accepted: 04/01/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Expedited discharge (within 24 hours) following lung resection has received scrutiny due to concerns for higher readmissions and paradoxically increased costs. The present study examined the impact of expedited discharge on hospitalization costs and unplanned readmissions using a nationally-representative sample. In addition, we sought to determine inter-hospital practice variation. METHODS Adults undergoing elective lobar or sublobar resection were identified using the 2016-2018 Nationwide Readmissions Database, while those with postoperative duration of hospitalization >5 days or experienced any perioperative complication, were excluded. Patients were classified as Expedited if postoperative hospitalization was 0 or 1 day and otherwise as Routine. Inverse probability of treatment weighing was utilized to adjust for intergroup differences. Hospitals were ranked according to risk-adjusted early discharge rates. Multivariable regression models were developed to assess the association of expedited discharge on nonelective 30-day readmissions as well as associated mortality and costs. RESULTS Of an estimated 84,152 patients, 13,834 (16.4%) comprised the Expedited group. Compared to Routine, Expedited were younger, less likely to have chronic obstructive pulmonary disease and undergo open procedures. Following adjustment, early discharge was associated with lower incremental costs (β coefficient: -$3.6K, 95%CI: -4.4 - -2.8) as well as similar readmissions (odds ratio: 0.89, 95%CI: 0.70 - 1.13) and related-mortality. Nearly half (48.1%) of all hospitals performed zero early discharges. CONCLUSIONS Expedited discharge following lung resection is a feasible management strategy and is associated with decreased costs and similar readmission risk compared to the norm. Select individuals should be strongly considered for expedited discharge following lung resection.
