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.

Establishing the Essential Role of Household Extenders for Surgeon Wellbeing.

OBJECTIVE: The aim of this study was to investigate the association between a change in household support during the Covid-19 pandemic and surgeon stress. BACKGROUND: The hours and unpredictability of surgical practice often necessitate the employment of household extenders (eg, child caregivers) to maintain a safe home environment for surgeons and their families. The Covid-19 pandemic destabilized these relationships and provided an opportunity to reflect on the role that household extenders play in a surgical household. METHODS: A multi-institutional telephone survey of surgeons practicing at five geographically diverse academic institutions was conducted (May 15, 2020-June 5, 2020). Surgeons were classified by change in household extenders (HE) during the pandemic (decrease, increase, no change, or none). The primary outcome was self-reported surgeon stress level. Multivariable linear regression was used to examine the relationship between change in HE and surgeon stress, adjusting for training and relationship status, the presence of pets and children in the household, and study site. RESULTS: The majority (182, 54.3%) of surgeons employed HE before the pandemic; 121 (36.1%) reported a decrease in HE during the pandemic, 9 (2.7%) reported an increase, and 52 (15.5%) reported no change. Stress scores varied significantly by change in HE group ( P = 0.016). After controlling for potential confounders, having an increase in HE was associated with a higher stress score (+1.55 points) than having no decrease in HE (P = 0.033), and having a decrease in HE was associated with a higher stress score (+0.96 points) than having no decrease ( P = 0.004). CONCLUSIONS: Household extenders play a vital and complex role in enabling the healthcare workforce to care of the population. Surgeons who experienced a change in household extenders reported the highest stress levels. We suggest that health systems should proactively support surgeons by supporting the household extender workforce.

Enhanced Recovery After Surgery (ERAS®) Society Consensus Guidelines for Emergency Laparotomy Part 3: Organizational Aspects and General Considerations for Management of the Emergency Laparotomy Patient.

BACKGROUND: This is Part 3 of the first consensus guidelines for optimal care of patients undergoing emergency laparotomy using an enhanced recovery after surgery (ERAS) approach. This paper addresses organizational aspects of care. METHODS: Experts in management of the high-risk and emergency general surgical patient were invited to contribute by the International ERAS® Society. PubMed, Cochrane, Embase, and MEDLINE database searches were performed for ERAS elements and relevant specific topics. Studies were selected with particular attention to randomized clinical trials, systematic reviews, meta-analyses and large cohort studies, and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation system. Recommendations were made on the best level of evidence, or extrapolation from studies on elective patients when appropriate. A modified Delphi method was used to validate final recommendations. RESULTS: Components of organizational aspects of care were considered. Consensus was reached after three rounds of a modified Delphi process. CONCLUSIONS: These guidelines are based on best current available evidence for organizational aspects of an ERAS® approach to patients undergoing emergency laparotomy and include discussion of less common aspects of care for the surgical patient, including end-of-life issues. These guidelines are not exhaustive but pull together evidence on important components of care for this high-risk patient population. As much of the evidence is extrapolated from elective surgery or emergency general surgery (not specifically laparotomy), many of the components need further evaluation in future studies.

Consensus Guidelines for Perioperative Care for Emergency Laparotomy Enhanced Recovery After Surgery (ERAS®) Society Recommendations Part 2-Emergency Laparotomy: Intra- and Postoperative Care.

BACKGROUND: This is Part 2 of the first consensus guidelines for optimal care of patients undergoing emergency laparotomy (EL) using an Enhanced Recovery After Surgery (ERAS) approach. This paper addresses intra- and postoperative aspects of care. METHODS: Experts in aspects of management of high-risk and emergency general surgical patients were invited to contribute by the International ERAS® Society. PubMed, Cochrane, Embase, and Medline database searches were performed for ERAS elements and relevant specific topics. Studies on each item were selected with particular attention to randomized clinical trials, systematic reviews, meta-analyses, and large cohort studies and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Recommendations were made on the best level of evidence, or extrapolation from studies on elective patients when appropriate. A modified Delphi method was used to validate final recommendations. Some ERAS® components covered in other guideline papers are outlined only briefly, with the bulk of the text focusing on key areas pertaining specifically to EL. RESULTS: Twenty-three components of intraoperative and postoperative care were defined. Consensus was reached after three rounds of a modified Delphi Process. CONCLUSIONS: These guidelines are based on best available evidence for an ERAS® approach to patients undergoing EL. These guidelines are not exhaustive but pull together evidence on important components of care for this high-risk patient population. As much of the evidence is extrapolated from elective surgery or emergency general surgery (not specifically laparotomy), many of the components need further evaluation in future studies.

Quality Improvement Initiative Implementation at the Unit or Hospital Level.

Quality improvement efforts take considerable commitment, including mentorship, training, and resources. Leveraging an established framework, such as that outlined by the American College of Surgeons, to design, implement, and analyze quality improvement projects offers the best chance for success. Herein, we illustrate the application of this framework to a gap in advance care planning for surgical patients. This article helps outline how to go from identifying and outlining a problem, to articulating a clearly defined project goal that is specific, measurable, attainable, relevant, and timebound, and later implementing and analyzing a gap in quality identified at the unit (e.g., service line, inpatient unit, clinic) or hospital level.

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.

Exploring the Experience of the Surgical Workforce During the Covid-19 Pandemic.

OBJECTIVE: To explore the impact of the Covid-19 pandemic on the stress levels and experience of academic surgeons by training status (eg, housestaff or faculty). BACKGROUND: Covid-19 has uniquely challenged and changed the United States healthcare system. A better understanding of the surgeon experience is necessary to inform proactive workforce management and support. METHODS: A multi-institutional, cross-sectional telephone survey of surgeons was conducted across 5 academic medical centers from May 15 to June 5, 2020. The exposure of interest was training status. The primary outcome was maximum stress level, measured using the validated Stress Numerical Rating Scale-11 (range 0-10). RESULTS: A total of 335 surveys were completed (49.3% housestaff, 50.7% faculty; response rate 63.7%). The mean maximum stress level of faculty was 7.21 (SD 1.81) and of housestaff was 6.86 (SD 2.06) (P = 0.102). Mean stress levels at the time of the survey trended lower amongst housestaff (4.17, SD 1.89) than faculty (4.56, SD 2.15) (P = 0.076). More housestaff (63.6%) than faculty (40.0%) reported exposure to individuals with Covid-19 (P < 0.001). Subjects reported inadequate personal protective equipment in approximately a third of professional exposures, with no difference by training status (P = 0.557). CONCLUSIONS: During the early months of the Covid-19 pandemic, the personal and professional experiences of housestaff and faculty differed, in part due to a difference in exposure as well as non-work-related stressors. Workforce safety, including adequate personal protective equipment, expanded benefits (eg, emergency childcare), and deliberate staffing models may help to alleviate the stress associated with disease resurgence or future disasters.

The Relationship Between Surgeon Gender and Stress During the Covid-19 Pandemic.

OBJECTIVE: To investigate the relationship between surgeon gender and stress during the Covid-19 pandemic. BACKGROUND: Although female surgeons face difficulties integrating work and home in the best of times, the Covid-19 pandemic has presented new challenges. The implications for the female surgical workforce are unknown. METHODS: This cross-sectional, multi-center telephone survey study of surgeons was conducted across 5 academic institutions (May 15-June 5, 2020). The primary outcome was maximum stress level, measured using the validated Stress Numerical Rating Scale-11. Mixed-effects generalized linear models were used to estimate the relationship between surgeon stress level and gender. RESULTS: Of 529 surgeons contacted, 337 surgeons responded and 335 surveys were complete (response rate 63.7%). The majority of female respondents were housestaff (58.1%), and the majority of male respondents were faculty (56.8%) (P = 0.008). A greater proportion of male surgeons (50.3%) than female surgeons (36.8%) had children ≤18 years (P = 0.015). The mean maximum stress level for female surgeons was 7.51 (SD 1.49) and for male surgeons was 6.71 (SD 2.15) (P < 0.001). After adjusting for the presence of children and training status, female gender was associated with a significantly higher maximum stress level (P < 0.001). CONCLUSIONS: Our findings that women experienced more stress than men during the Covid-19 pandemic, regardless of parental status, suggest that there is more to the gendered differences in the stress experience of the pandemic than the added demands of childcare. Deliberate interventions are needed to promote and support the female surgical workforce during the pandemic.

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.

Guidelines for Perioperative Care for Emergency Laparotomy Enhanced Recovery After Surgery (ERAS) Society Recommendations: Part 1-Preoperative: Diagnosis, Rapid Assessment and Optimization.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) protocols reduce length of stay, complications and costs for a large number of elective surgical procedures. A similar, structured approach appears to improve outcomes, including mortality, for patients undergoing high-risk emergency general surgery, and specifically emergency laparotomy. These are the first consensus guidelines for optimal care of these patients using an ERAS approach. METHODS: Experts in aspects of management of the high-risk and emergency general surgical patient were invited to contribute by the International ERAS® Society. Pubmed, Cochrane, Embase, and MEDLINE database searches on English language publications were performed for ERAS elements and relevant specific topics. Studies on each item were selected with particular attention to randomized controlled trials, systematic reviews, meta-analyses and large cohort studies, and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Recommendations were made on the best level of evidence, or extrapolation from studies on non-emergency patients when appropriate. The Delphi method was used to validate final recommendations. The guideline has been divided into two parts: Part 1-Preoperative Care and Part 2-Intraoperative and Postoperative management. This paper provides guidelines for Part 1. RESULTS: Twelve components of preoperative care were considered. Consensus was reached after three rounds. CONCLUSIONS: These guidelines are based on the best available evidence for an ERAS approach to patients undergoing emergency laparotomy. Initial management is particularly important for patients with sepsis and physiological derangement. These guidelines should be used to improve outcomes for these high-risk patients.

Impact of the coronavirus disease 2019 pandemic on an academic vascular practice and a multidisciplinary limb preservation program.

With the aggressive resource conservation necessary to face the coronavirus disease 2019 pandemic, vascular surgeons have faced unique challenges in managing the health of their high-risk patients. An early analysis of patient outcomes after pandemic-related practice changes suggested that patients with chronic limb threatening ischemia have been presenting with more severe foot infections and are more likely to require major limb amputation compared with 6 months previously. As our society and health care system adapt to the new changes required in the post-coronavirus disease 2019 era, it is critical that we pay special attention to the most vulnerable subsets of patients with vascular disease, particularly those with chronic limb threatening ischemia and limited access to care.

High Compliance to an Enhanced Recovery Pathway for Patients ≥65 Years Undergoing Major Small and Large Intestinal Surgery Is Associated With Improved Postoperative Outcomes.

OBJECTIVE: This study was performed to evaluate compliance to an Enhanced Recovery Pathway (ERP) among patients ≥65 years and determine the effect of compliance on postoperative outcomes. SUMMARY BACKGROUND DATA: ERPs improve postoperative outcomes in patients undergoing major surgery. Given the inherent decline of the older surgical patient, the benefit of an ERP in this population has been questioned. METHODS: Patients undergoing major small and large intestinal surgery prior to and following ERP implementation at the Johns Hopkins Medical Institutions were entered into the ACS-NSQIP database. Outcomes included ERP compliance rates, complications, length of stay (LOS), and 30-day readmission rates were determined for older patients. RESULTS: Nine hundred seventy-four patients (693 < 65 yrs and 281 ≥ 65 yrs) were included. Of those ≥ 65 years, 142 (51%) were entered prior to and 139 (49%) were entered following ERP implementation. More ERP than pre-ERP patients underwent laparoscopic procedures (45.3% vs. 32.4%, P = 0.02), had disseminated malignancies (9.4% vs. 2.8%, P = 0.03), and smoked (14.4% vs. 4.9%, P = 0.01). Overall compliance was 74.5%, and 47% of older ERP patients achieved high compliance (≥75% compliance with ERP variables). High compliance was associated with a 30% decrease LOS (IRR: 0.7 P = 0.001) and 60% decrease in major (CD ≥ II) complications (OR: 0.4 P = 0.05). CONCLUSION: LOS and complication rates following implementation of an ERP were significantly improved in highly compliant elderly patients. Interventions to further improve outcomes should target decreasing variability by increasing individual compliance with an effective clinical pathway.
