Implementing Enhanced Recovery Pathways: A Qualitative Study of Factors That Distinguished Higher Performing Hospitals.

OBJECTIVE: The aim of this study was to explore barriers and facilitators to implementing enhanced recovery pathways, with a focus on identifying factors that distinguished hospitals achieving greater levels of implementation success. BACKGROUND: Despite the clinical effectiveness of enhanced recovery pathways, the implementation of these complex interventions varies widely. While there is a growing list of contextual factors that may affect implementation, little is known about which factors distinguish between higher and lower levels of implementation success. METHODS: We conducted in-depth interviews with 168 perioperative leaders, clinicians, and staff from 8 US hospitals participating in the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery. Guided by the Consolidated Framework for Implementation Research, we coded interview transcripts and conducted a thematic analysis of implementation barriers and facilitators. We also rated the perceived effect of factors on different levels of implementation success, as measured by hospitals' adherence with 9 process measures over time. RESULTS: Across all hospitals, factors with a consistently positive effect on implementation included information-sharing practices and the implementation processes of planning and engaging. Consistently negative factors included the complexity of the pathway itself, hospitals' infrastructure, and the implementation process of "executing" (particularly in altering electronic health record systems). Hospitals with the greatest improvement in process measure adherence were distinguished by clinicians' positive knowledge and beliefs about pathways and strong leadership support from both clinicians and executives. CONCLUSION: We draw upon diverse perspectives from across the perioperative continuum of care to qualitatively describe implementation factors most strongly associated with successful implementation of enhanced recovery pathways.

Association of Housing Status With Types of Operations and Postoperative Health Care Utilization.

OBJECTIVE: To analyze the association between housing status and the nature of surgical care provided, health care utilization, and operational outcomes. BACKGROUND: Unhoused patients have worse outcomes and higher health care utilization across multiple clinical domains. However, little has been published describing the burden of surgical disease in unhoused patients. METHODS: We conducted a retrospective cohort study of 111,267 operations from 2013 to 2022 with housing status documented at a single, tertiary care institution. We conducted unadjusted bivariate and multivariate analyses adjusting for sociodemographic and clinical characteristics. RESULTS: A total of 998 operations (0.8%) were performed for unhoused patients, with a higher proportion of emergent operations than housed patients (56% vs 22%). In unadjusted analysis, unhoused patients had longer length of stay (18.7 vs 8.7 days), higher readmissions (9.5% vs 7.5%), higher in-hospital (2.9% vs 1.8%) and 1-year mortality (10.1% vs 8.2%), more in-hospital reoperations (34.6% vs 15.9%), and higher utilization of social work, physical therapy, and occupational therapy services. After adjusting for age, sex, comorbidities, insurance status, and indication for operation, as well as stratifying by emergent versus elective operation, these differences went away for emergent operations. CONCLUSIONS: In this retrospective cohort analysis, unhoused patients more commonly underwent emergent operations than their housed counterparts and had more complex hospitalizations on an unadjusted basis that largely disappeared after adjustment for patient and operative characteristics. These findings suggest issues with upstream access to surgical care that, when unaddressed, may predispose this vulnerable population to more complex hospitalizations and worse longer term outcomes.

Pandemic Recovery: Persistent Disparities in Access to Elective Surgical Procedures.

OBJECTIVE: To examine potential disparities in patient access to elective procedures during the recovery phase of the COVID-19 pandemic. SUMMARY OF BACKGROUND DATA: Elective surgeries during the pandemic were limited acutely. Access to surgical care was restored in a recovery phase but backlogs and societal shifts are hypothesized to impact surgical access. METHODS: Adults with electronic health record orders for procedures ("procedure requests"), from March 16 to August 25, 2019 and March 16 to August 25, 2020, were included. Logistic regression was performed for requested procedures that were not scheduled. Linear regression was performed for wait time from request to scheduled or completed procedure. RESULTS: The number of patients with procedure requests decreased 20.8%, from 26,789 in 2019 to 21,162 in 2020. Patients aged 36-50 and >65 years, those speaking non-English languages, those with Medicare or no insurance, and those living >100 miles away had disproportionately larger decreases. Requested procedures had significantly increased adjusted odds ratios (aORs) of not being scheduled for patients with primary languages other than English, Spanish, or Cantonese [aOR 1.60, 95% confidence interval (CI) 1.12-2.28]; unpartnered marital status (aOR 1.21, 95% CI 1.07-1.37); uninsured or self-pay (aOR 2.03, 95% CI 1.53-2.70). Significantly longer wait times were seen for patients aged 36-65 years; with Medi-Cal insurance; from ZIP codes with lower incomes; and from ZIP codes >100 miles away. CONCLUSIONS: Patient access to elective surgeries decreased during the pandemic recovery phase with disparities based on patient age, language, marital status, insurance, socioeconomic status, and distance from care. Steps to address modifiable disparities have been taken.

Bacterial Decontamination: Bowel Preparation and Chlorhexidine Bathing.

Infectious complications following bowel surgery continues to be a leading cause of postoperative morbidity. Both patient- and procedure-related factors contribute to risk. Compliance with evidence-based process measures is the best strategy for prevention of surgical site infections. Three process measures that aim to reduce the bacterial load present at the time of surgery are mechanical bowel preparation, oral antibiotics, and chlorhexidine bathing. There is heightened awareness of surgical site infections, in part due to improved access to reliable postoperative complication data for colon surgery as well as incorporation of surgical site infection into public reporting and pay-for-performance payment models. As a result, the literature has improved with regard to the effectiveness of these methods in reducing infectious complications. Herein, we provide the evidence to support adoption of these practices into colorectal surgery infection prevention programs.

Accelerating Surgical Site Infection Abstraction With a Semi-automated Machine-learning Approach.

OBJECTIVE: To demonstrate that a semi-automated approach to health data abstraction provides significant efficiencies and high accuracy. BACKGROUND: Surgical outcome abstraction remains laborious and a barrier to the sustainment of quality improvement registries like ACS-NSQIP. A supervised machine learning algorithm developed for detecting SSi using structured and unstructured electronic health record data was tested to perform semi-automated SSI abstraction. METHODS: A Lasso-penalized logistic regression model with 2011-3 data was trained (baseline performance measured with 10-fold cross-validation). A cutoff probability score from the training data was established, dividing the subsequent evaluation dataset into "negative" and "possible" SSI groups, with manual data abstraction only performed on the "possible" group. We evaluated performance on data from 2014, 2015, and both years. RESULTS: Overall, 6188 patients were in the 2011-3 training dataset and 5132 patients in the 2014-5 evaluation dataset. With use of the semi-automated approach, applying the cut-off score decreased the amount of manual abstraction by >90%, resulting in < 1% false negatives in the "negative" group and a sensitivity of 82%. A blinded review of 10% of the "possible" group, considering only the features selected by the algorithm, resulted in high agreement with the gold standard based on full chart abstraction, pointing towards additional efficiency in the abstraction process by making it possible for abstractors to review limited, salient portions of the chart. CONCLUSION: Semi-automated machine learning-aided SSI abstraction greatly accelerates the abstraction process and achieves very good performance. This could be translated to other post-operative outcomes and reduce cost barriers for wider ACS-NSQIP adoption.

Opioid prescribing practices at hospital discharge for surgical patients before and after the Centers for Disease Control and Prevention's 2016 opioid prescribing guideline.

BACKGROUND: The Centers for Disease Control and Prevention's (CDC) March 2016 opioid prescribing guideline did not include prescribing recommendations for surgical pain. Although opioid over-prescription for surgical patients has been well-documented, the potential effects of the CDC guideline on providers' opioid prescribing practices for surgical patients in the United States remains unclear. METHODS: We conducted an interrupted time series analysis (ITSA) of 37,009 opioid-naïve adult patients undergoing inpatient surgery from 2013-2019 at an academic medical center. We assessed quarterly changes in the discharge opioid prescription days' supply, daily and total doses in oral morphine milligram equivalents (OME), and the proportion of patients requiring opioid refills within 30 days of discharge. RESULTS: The discharge opioid prescription declined by -0.021 (95% CI, -0.045 to 0.003) days per quarter pre-guideline versus -0.201 (95% CI, -0.223 to -0.179) days per quarter post-guideline (p < 0.0001). Likewise, the mean daily and total doses of the discharge opioid prescription declined by -0.387 (95% CI, -0.661 to -0.112) and -7.124 (95% CI, -9.287 to -4.962) OME per quarter pre-guideline versus -2.307 (95% CI, -2.560 to -2.055) and -20.68 (95% CI, -22.66 to -18.69) OME per quarter post-guideline, respectively (p < 0.0001). Opioid refill prescription rates remained unchanged from baseline. CONCLUSIONS: The release of the CDC opioid guideline was associated with a significant reduction in discharge opioid prescriptions without a concomitant increase in the proportion of surgical patients requiring refills within 30 days. The mean prescription for opioid-naïve surgical patients decreased to less than 3 days' supply and less than 50 OME per day by 2019.

Successful Implementation of Enhanced Recovery in Elective Colorectal Surgery is Variable and Dependent on the Local Environment.

OBJECTIVE: To evaluate local hospital success with enhanced recovery implementation as measured by colorectal surgery process measure (PM) compliance and characterize local environment factors associated with success within a contemporary quality improvement collaborative. SUMMARY BACKGROUND DATA: Enhanced recovery programs (ERP) have proven an effective perioperative quality improvement strategy, but local variation in implementation can hinder patient outcome improvement. METHODS: Individual hospitals participating in a national colorectal ERP quality improvement program were evaluated with quantitative (patient-level process and outcome) and qualitative (survey and structured interviews with hospital teams) data between 2017 and 2020. Hospitals with implementation success were identified: high performers (80% of elective colorectal surgery patients compliant with >6/9 PMs) and high improvers (top quartile of PM adherence improvement over time). Hospital and implementation characteristics were compared with chi-square tests. Trends in average annual outcome change were estimated with logistic and linear regression. RESULTS: Of 207 total hospitals, 62 were characterized as High Performance and 52 as High Improvement. High Performance hospitals were larger, with more annual colorectal surgeries (128 vs 101, P = 0.039). Qualitative assessment revealed fewer barriers of staff buy-in and competing priorities, and more experience with standardized perioperative care in High Performance hospitals. High Improvement hospitals had lower baseline PM adherence (54.1% vs 69.6%, P < 0.001) and less experience with standardized perioperative care (30.8% vs 58.1%, P < 0.001) but were noted to have a positive trend in annual patient outcomes: annual morbidity (Δ-1.14% vs -0.20%, P = 0.035), readmission (Δ-1.85% vs 0.002%, P = 0.037), and prolonged length of stay (Δ-3.94 vs -1.19, P = 0.037) compared to Low Improvement hospitals. CONCLUSIONS: When evaluating a collection of hospitals implementing ERP, only half of hospitals reached consistent High Performance or high improvement. Characteristics of the local environment need further study to understand the barriers to effective implementation in a pragmatic setting.

Instilling Resiliency in Surgical Education: The Benefits of Longitudinal Medical Student Learning.

The longitudinal clerkship has been recognized as an innovative, unique model in medical education that demonstrates significantly higher student and preceptor satisfaction with comparable long-term outcomes like performance on standardized examinations. At the center of this model is the student-preceptor relationship, which promotes effective student-directed learning and personal and professional relationships with established faculty mentors. The University of California, San Francisco (UCSF) has two clerkships models: a traditional or "block" model consisting of 2-month sequential clinical rotations in seven core clerkships, and a longitudinal model that integrates parallel out-patient clinical experiences over the entire year with one-on-one faculty preceptors from each core discipline with focused 2-week intensive inpatient rotations. In the setting of the Covid-19 pandemic beginning in Spring of 2020, this arrangement allowed for a natural experiment to evaluate the resiliency of the respective models in the face of unprecedented disruptions in education and healthcare delivery. As described in this perspective, both clerkships required rapid pivots; however, students enrolled in the longitudinal clerkship were more likely to develop stronger relationships with surgical faculty and felt more prepared for making career choices. Medical school curricula may benefit from incorporating longitudinal components, as this model provided flexibility and fostered greater faculty-student mentorship in the setting of disruption to medical education.

Patient Perceptions on Barriers and Facilitators to Accessing Low-acuity Surgery During COVID-19 Pandemic.

BACKGROUND: The onset of the COVID-19 pandemic led to the postponement of low-acuity surgical procedures in an effort to conserve resources and ensure patient safety. This study aimed to characterize patient-reported concerns about undergoing surgical procedures during the pandemic. METHODS: We administered a cross-sectional survey to patients who had their general and plastic surgical procedures postponed at the onset of the pandemic, asking about barriers to accessing surgical care. Questions addressed dependent care, transportation, employment and insurance status, as well as perceptions of and concerns about COVID-19. Mixed methods and inductive thematic analyses were conducted. RESULTS: One hundred thirty-five patients were interviewed. We identified the following patient concerns: contracting COVID-19 in the hospital (46%), being alone during hospitalization (40%), facing financial stressors (29%), organizing transportation (28%), experiencing changes to health insurance coverage (25%), and arranging care for dependents (18%). Nonwhite participants were 5 and 2.5 times more likely to have concerns about childcare and transportation, respectively. Perceptions of decreased hospital safety and the consequences of possible COVID-19 infection led to delay in rescheduling. Education about safety measures and communication about scheduling partially mitigated concerns about COVID-19. However, uncertainty about timeline for rescheduling and resolution of the pandemic contributed to ongoing concerns. CONCLUSIONS: Providing effective surgical care during this unprecedented time requires both awareness of societal shifts impacting surgical patients and system-level change to address new barriers to care. Eliciting patients' perspectives, adapting processes to address potential barriers, and effectively educating patients about institutional measures to minimize in-hospital transmission of COVID-19 should be integrated into surgical care.

Evidence Review Conducted for the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery: Focus on Anesthesiology for Colorectal Surgery.

The Agency for Healthcare Research and Quality, in partnership with the American College of Surgeons and the Johns Hopkins Medicine Armstrong Institute for Patient Safety and Quality, has developed the Safety Program for Improving Surgical Care and Recovery (ISCR), which is a national effort to disseminate best practices in perioperative care to more than 750 hospitals across multiple procedures in the next 5 years. The program will integrate evidence-based processes central to enhanced recovery and prevention of surgical site infection, venous thromboembolic events, catheter-associated urinary tract infections with socioadaptive interventions to improve surgical outcomes, patient experience, and perioperative safety culture. The objectives of this review are to evaluate the evidence supporting anesthesiology components of colorectal (CR) pathways and to develop an evidence-based CR protocol for implementation. Anesthesiology protocol components were identified through review of existing CR enhanced recovery pathways from several professional associations/societies and expert feedback. These guidelines/recommendations were supplemented by evidence made further literature searches. Anesthesiology protocol components were identified spanning the immediate preoperative, intraoperative, and postoperative phases of care. Components included carbohydrate loading, reduced fasting, multimodal preanesthesia medication, antibiotic prophylaxis, blood transfusion, intraoperative fluid management/goal-directed fluid therapy, normothermia, a standardized intraoperative anesthesia pathway, and standard postoperative multimodal analgesic regimens.

Evidence Review Conducted for the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery: Focus on Anesthesiology for Bariatric Surgery.

Enhanced recovery after surgery protocols for bariatric surgery are increasingly being implemented, and reports suggest that they may be associated with superior outcomes, reduced length of hospital stay, and cost savings. The Agency for Healthcare Research and Quality, in partnership with the American College of Surgeons and the Johns Hopkins Medicine Armstrong Institute for Patient Safety and Quality, has developed the Safety Program for Improving Surgical Care and Recovery. We have conducted an evidence review to select anesthetic interventions that positively influence outcomes and facilitate recovery after bariatric surgery. A literature search was performed for each intervention, and the highest levels of available evidence were considered. Anesthesiology-related interventions for pre- (carbohydrate loading/fasting, multimodal preanesthetic medications), intra- (standardized intraoperative pathway, regional anesthesia, opioid minimization and multimodal analgesia, protective ventilation strategy, fluid minimization), and postoperative (multimodal analgesia with opioid minimization) phases of care are included. We have summarized the best available evidence to recommend the anesthetic components of care for enhanced recovery after surgery for bariatric surgery. There is evidence in the literature, and from society guidelines, to support the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery goals for bariatric surgery.

Evidence Review Conducted for the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery: Focus on Anesthesiology for Total Hip Arthroplasty.

Successes using enhanced recovery after surgery (ERAS) protocols for total hip arthroplasty (THA) are increasingly being reported. As in other surgical subspecialties, ERAS for THA has been associated with superior outcomes, improved patient satisfaction, reduced length of hospital stay, and cost savings. Nonetheless, the adoption of ERAS to THA has not been universal. The Agency for Healthcare Research and Quality, in partnership with the American College of Surgeons and the Johns Hopkins Medicine Armstrong Institute for Patient Safety and Quality, has developed the Safety Program for Improving Surgical Care and Recovery. We have conducted an evidence review to select anesthetic interventions that positively influence outcomes and facilitate recovery after THA. A literature search was performed for each intervention, and the highest levels of available evidence were considered. Anesthesiology-related interventions for pre- (carbohydrate loading/fasting, multimodal preanesthetic medications), intra- (standardized intraoperative pathway, regional anesthesia, ventilation, tranexamic acid, fluid minimization, glycemic control), and postoperative (multimodal analgesia) phases of care are included. We have summarized the best available evidence to recommend the anesthetic components of care for ERAS for THA. There is evidence in the literature and from society guidelines to support the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery goals for THA.

Evidence Review Conducted for the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery: Focus on Anesthesiology for Hip Fracture Surgery.

Enhanced recovery after surgery (ERAS) protocols represent patient-centered, evidence-based, multidisciplinary care of the surgical patient. Although these patterns have been validated in numerous surgical specialities, ERAS has not been widely described for patients undergoing hip fracture (HFx) repair. As part of the Agency for Healthcare Research and Quality Safety Program for Improving Surgical Care and Recovery, we have conducted a full evidence review of interventions that form the basis of the anesthesia components of the ERAS HFx pathway. A literature search was performed for each protocol component, and the highest levels of evidence available were selected for review. Anesthesiology components of care were identified and evaluated across the perioperative continuum. For the preoperative phase, the use of regional analgesia and nonopioid multimodal analgesic agents is suggested. For the intraoperative phase, a standardized anesthetic with postoperative nausea and vomiting prophylaxis is suggested. For the postoperative phase, a multimodal (primarily nonopioid) analgesic regimen is suggested. A summary of the best available evidence and recommendations for inclusion in ERAS protocols for HFx repair are provided.

Enhanced Recovery after Surgery for Colorectal Surgery: A Review of the Economic Implications.

Enhanced Recovery After Surgery (ERAS) programs are transdisciplinary, evidence-based perioperative protocols that aim to standardize best practices and increase the value of delivered healthcare. Quality improvement programs such as ERAS for colorectal surgery have been linked to a reduction in rates of hospital-acquired infections (HAIs) including surgical site infection as well as a reduction in overall length of stay. Importantly, to achieve these results, hospitals must commit to fostering transdisciplinary collaboration across surgery, anesthesiology, and nursing, as well as alignment between frontline providers and hospital executives. This requires upfront investment as well as ongoing resource allocation to sustain the program but given the magnitude of the potential impact of a successful ERAS program on multiple domains of quality and safety, the investment will easily reap ongoing rewards. The purpose of this manuscript is to outline implementation and sustainability costs of an ERAS program as well as discuss the potential cost savings related to the program to further inform hospitals considering adoption of this approach to care.

Prognostic and Predictive Clinicopathologic Factors of Squamous Anal Canal Cancer in HIV-Positive and HIV-Negative Patients: Does HAART Influence Outcomes?

BACKGROUND: The incidence of squamous cell carcinoma (SCC) of the anal canal has been rising over the past decades, especially in patients infected with human immunodeficiency virus (HIV). Despite the advent of potent multidrug regimens to treat HIV-termed highly active antiretroviral therapy (HAART), anal SCC rates have not declined, and the impact of HAART on anal SCC remains controversial. AIM: The purpose of this study was to define outcomes of anal SCC treatment in HIV-positive and HIV-negative patients. METHODS AND MATERIALS: A retrospective single-institution analysis was performed on all patients with anal SCC treated at the Johns Hopkins Hospital between 1991 and 2010. The primary outcomes measured were 5-year overall survival (5-year OS), median survival, and relapse rates. RESULTS: Our search identified 93 patients with anal SCC. Patients had a mean age of 54 years; 37.6% were male, and 21.5% were HIV-positive. Median follow-up was 28 months. Relapse occurred in 16.1% of patients. Median time to relapse was 20 months. Relapse rates were slightly higher with HIV-positive versus negative patients (30.0 vs. 12.3%) but did not reach statistical significance (p = 0.06). Among HIV-positive patients, those who relapsed were more likely to be on HAART than those who did not relapse (83.3 vs. 14.3%, p = 0.007). 5-year OS was 58.9% for the total group of patients with no significant difference between those who relapsed versus those who did not (76.2 vs. 54.5%, p = 0.20). No survival difference was seen between HIV-positive and negative patients. Survival was associated with AJCC stage in all patients. CONCLUSION: In our small series, HIV infection was not associated with a significantly higher relapse rate or worse 5-year OS among patients with anal SCC. HAART was associated with a higher rate of relapse in HIV-positive patients. AJCC staging predicted survival in both relapsed and non-relapsed patients regardless of HIV status.

Review of the enhanced recovery pathway for children: perioperative anesthetic considerations.

PURPOSE: Enhanced recovery after surgery (ERAS) pathways have been used for two decades to improve perioperative recovery in adults. Nevertheless, little is known about their effectiveness in children. The purpose of this review was to consider pediatric ERAS pathways, review the literature concerned with their potential benefit, and compare them with adult ERAS pathways. SOURCE: A PubMed literature search was performed for articles that included the terms enhanced recovery and/or fast track in the pediatric perioperative period. Pediatric patients included those from the neonatal period through teenagers and/or youths. PRINCIPAL FINDINGS: The literature search revealed a paucity of articles about pediatric ERAS. This lack of academic investigation is likely due in part to the delayed acceptance of ERAS in the pediatric surgical arena. Several pediatric studies examined individual components of adult-based ERAS pathways, but the overall study of a comprehensive multidisciplinary ERAS protocol in pediatric patients is lacking. CONCLUSION: Although adult ERAS pathways have been successful at reducing patient morbidity, the translation, creation, and utility of instituting pediatric ERAS pathways have yet to be realized.

Treating Wisely: The Surgeon's Role in Antibiotic Stewardship.

: Antibiotic resistance continues to receive national attention as a leading public health threat. In 2015, President Barack Obama proposed a National Action Plan to Combat Antibiotic-Resistant Bacteria to curb the rise of "superbugs," bacteria resistant to antibiotics of last resort. Whereas many antibiotics are prescribed appropriately to treat infections, there continue to be a large number of inappropriately prescribed antibiotics. Although much of the national attention with regards to stewardship has focused on primary care providers, there is a significant opportunity for surgeons to embrace this national imperative and improve our practices. Local quality improvement efforts suggest that antibiotic misuse for surgical disease is common. Opportunities exist as part of day-to-day surgical care as well as through surgeons' interactions with nonsurgeon colleagues and policy experts. This article discusses the scope of the antibiotic misuse in surgery for surgical patients, and provides immediate practice improvements and also advocacy efforts surgeons can take to address the threat. We believe that surgical antibiotic prescribing patterns frequently do not adhere to evidence-based practices; surgeons are in a position to mitigate their ill effects; and antibiotic stewardship should be a part of every surgeons' practice.

Impact of Enhanced Recovery After Surgery and Fast Track Surgery Pathways on Healthcare-associated Infections: Results From a Systematic Review and Meta-analysis.

OBJECTIVE: The aim of this study was to establish if enhanced recovery after surgery (ERAS) and fast track surgery (FTS) protocols are associated with reduction in healthcare-associated infection (HAIs). BACKGROUND: Evidence suggests that prevention strategies for HAIs should be multifaceted and transdisciplinary. ERAS and FTS protocols are collaborative approaches to perioperative care which reduce length of stay but may also be an effective strategy for reducing HAIs. METHODS: We performed a meta-analysis of randomized trials involving either ERAS or FTS for abdominal or pelvic surgery. Primary outcome included postoperative incidence of 3 major HAIs: lung infection (LI), urinary tract infection (UTI), and surgical site infection (SSI). RESULTS: Among all included trials, ERAS/FTS was associated with a significant reduction in postoperative LI [risk ratio (RR) = 0.38; 95% confidence interval (CI) = 0.23-0.61; P < 0.0001; I = 0%], UTI (RR = 0.42; 95% CI = 0.23-0.76; P = 0.004; I = 0%), and SSI (RR = 0.75; 95% CI = 0.58-0.98; P = 0.04; I = 0%) compared with conventional controls. Sensitivity analysis performed following the exclusion of high risk of bias publications did not appreciably affect these results. ERAS/FTS was also associated with a significant decrease in hospital length of stay (standard mean difference = -0.83; 95% CI = -0.92 to -0.75; P < 0.0001; P for heterogeneity <0.0001, I = 93%). Subgroup analysis of trials involving colorectal surgery and open incision also resulted in significant reduction in all 3 HAIs among ERAS/FTS compared with conventional counterparts. CONCLUSIONS: Our results suggest ERAS/FTS protocols are powerful tools to prevent HAIs. Further study is needed to establish the mechanism. Providers should consider adoption of similar transdisciplinary programs to reduce perioperative HAIs and at the same time improve the value of surgical care.
