Emergency general surgery transfer to lower acuity facility: The role of right-sizing care in emergency general surgery regionalization

Acute Care Surgery Model: High Quality Care for Higher Risk Populations

INTRODUCTION

Emergency General Surgery (EGS) represent a wide spectrum of diseases with high complication and mortality rates. Race, insurance, and socioeconomic status have been associated with mortality in EGS patients. Acute care surgery (ACS) models have previously shown improved outcomes for EGS patients. We hypothesized that transition to an ACS model would increase access to care for underserved and higher risk EGS patients in a community hospital, without a change in mortality.

METHODS

This retrospective cohort study included adult EGS patients from 2017 to 2021 with current procedural terminology (CPT) codes of colectomy, small-bowel resection, peptic-ulcer surgery, appendectomy, or cholecystectomy. In July 2020, the hospital transitioned from a traditional model to an ACS model. Patients were analyzed for 42-month before (pre-ACS) and 18-month after (post-ACS) transition. Primary outcome was mortality; secondary outcomes were 30-day postoperative emergency department visits and readmission.

RESULTS

We analyzed 467 pre-ACS and 238 post-ACS patients. After transition, patients were more likely to be Black, older, self-pay, and have higher Elixhauser Comorbidity Index (ECI) scores. Rates of cholecystectomies increased and appendectomies decreased after transition. Adjusting for age, race, and ECI, there were no changes in 30-day all-cause mortality (0.9% versus 2.1%, P = 0.63), length of stay (2.7-days versus 3-days, P = 0.91) and rate of postop emergency department visits (7.5% versus 11.3%, P = 0.16). There was a significant increase in hospital readmission after the ACS transition (5.1 versus 10.5%, P = 0.001, odds ratio 5.3).

CONCLUSIONS

After implementation of an ACS model, we found an increase in EGS patients who were older, Black, underinsured, with higher ECI without change in mortality. Implementation of ACS models at community hospitals may increase access to quality care for underserved and higher risk patient populations.

Does practice make perfect? The impact of hospital and surgeon volume on complications after intra-abdominal procedures

BACKGROUND

There is increasing interest in the regionalization of surgical procedures. However, evidence on the volume-outcome relationship for emergency intra-abdominal surgery is not well-synthesized. This systematic review and meta-analysis summarize evidence regarding the impact of hospital and surgeon volume on complications.

METHODS

We identified cohort studies assessing the impact of hospital/surgeon volume on postoperative complications after emergency intra-abdominal procedures, with data collected after the year 2000 through a literature search without language restriction in the PubMed, Web of Science, and Cochrane databases. A weighted overall complication rate was calculated, and a random effect regression model was used for a summary odds ratio. A sensitivity analysis with the removal of studies contributing to heterogeneity was performed (PROSPERO: CRD42022358879).

RESULTS

The search yielded 2,153 articles, of which 9 cohort studies were included and determined to be good quality according to the Newcastle Ottawa Scale. These studies reported outcomes for the following procedures: cholecystectomy, colectomy, appendectomy, small bowel resection, peptic ulcer repair, adhesiolysis, laparotomy, and hernia repair. Eight studies (2,358,093 patients) with available data were included in the meta-analysis. Low hospital volume was not significantly associated with higher complications. In the sensitivity analysis, low hospital volume was significantly associated with higher complications when appropriate heterogeneity was achieved. Low surgeon volume was associated with higher complications, and these findings remained consistent in the sensitivity analysis.

CONCLUSION

We found that hospital and surgeon volume was significantly associated with higher complications in patients undergoing emergency intra-abdominal surgery when appropriate heterogeneity was achieved.

Remote triage practices in general surgery patients from freestanding emergency departments: A 6-year analysis

BACKGROUND

Freestanding emergency departments have risen in popularity as a means to expand access to care. Although some evaluation of freestanding emergency department utility in specific patient populations exists, management of surgical patients via remote triage and disposition has not been previously described. We report our experience with remote triage to discharge home, level I trauma center, or community hospital admission for general surgery patients who present to an affiliated freestanding emergency department.

METHODS

A retrospective cohort study of patients presenting to freestanding emergency departments requiring surgical consultation between 2016 and 2021 was conducted. Outcomes included disposition, length of stay, surgical intervention, 30-day mortality, and readmission. Undertriage and overtriage rates were calculated and defined as the following: (1) discharge undertriage-discharge home with 30-day emergency department visit/readmission; 2) transfer undertriage-transfers to community hospital requiring transfer to trauma center; and (3) overtriage-admissions <24 hours without surgery.

RESULTS

Of 1,105 patients, 15% were discharged home, 27% were transferred to trauma centers, and 58% were transferred to community hospitals. Patients admitted to trauma centers were older and had higher acuity pathology, whereas patients admitted to community hospitals had higher operative rates with shorter lengths of stay, operating room time, 30-day readmission, and mortality. Transfer undertriage was 0.9% (n = 6), with only 1 patient requiring transfer from a community hospital to a trauma center for disease acuity. Discharge undertriage was 12% (n = 20) due to worsening or persistent pathology. Overtriage was 5.5% (n = 52), with most having a partial small bowel obstruction or ambiguous diagnostic imaging requiring observation.

CONCLUSION

Remote surgery triage at freestanding emergency departments, without an in-person examination, demonstrated both low undertriage and overtriage rates, reflecting appropriate triage practices.

Virtual triage from freestanding emergency departments: a propensity score-weighted analysis of short-term outcomes in emergency general surgery

BACKGROUND

Freestanding emergency departments (FSEDs) have generated improved hospital metrics, including decreased ED wait times and increased patient selection. Patient outcomes and process safety have not been evaluated. This study investigates the safety of FSED virtual triage in the emergency general surgery (EGS) patient population.

METHODS AND PROCEDURES

A retrospective review evaluated all adult EGS patients admitted to a community hospital between January 2016 and December 2021 who either presented at a FSED and received virtual evaluation from a surgical team (fEGS) or presented at the community hospital emergency department and received in-person evaluation from the same surgical group (cEGS). Patients' demographics, acute care utilization history, and clinical characteristics at the onset of the index visit were used to build a propensity score model and stabilized Inverse Probability of Treatment Weights (IPTW) were used to create a weighted sample. Multivariable regression models were then employed to the weighted sample to evaluate the treatment effect of virtual triage compared to in-person evaluation on short-term outcomes, including length of stay (LOS) and 30-day readmission and mortality. Variables which occurred during the index visit (such as surgery duration and type of surgery) were adjusted for in the multivariable analyses.

RESULTS

Of 1962 patients, 631 (32.2%) were initially evaluated virtually (fEGS) and 1331 (67.8%) underwent an in-person evaluation (cEGS). Baseline characteristics demonstrated significant differences between the cohorts in gender, race, payer status, BMI, and CCI score. Baseline risks were well balanced in the IPTW-weighted sample (SD range 0.002-0.18). Multivariable analysis found no significant differences between the balanced cohorts in 30-day readmission, 30-day mortality, and LOS (p > 0.05 for all).

CONCLUSION

Patients who undergo virtual triage have similar outcomes to those who undergo in-person triage for EGS diagnoses. Virtual triage at FSED for these EGS patients may be an efficient and safe means for initial evaluation.

Greater patient sharing between hospitals is associated with better outcomes for transferred emergency general surgery patients

BACKGROUND

Access to emergency surgical care has declined as the rural workforce has decreased. Interhospital transfers of patients are increasingly necessary, and care coordination across settings is critical to quality care. We characterize the role of repeated hospital patient sharing in outcomes of transfers for emergency general surgery (EGS) patients.

METHODS

A multicenter study of Wisconsin inpatient acute care hospital stays that involved transfer of EGS patients using data from the Wisconsin Hospital Association, a statewide hospital discharge census for 2016 to 2018. We hypothesized that higher proportion of patients transferred between hospitals would result in better outcomes. We examined the association between the proportion of EGS patients transferred between hospitals and patient outcomes, including in-hospital morbidity, mortality, and length of stay. Additional variables included hospital organizational characteristics and patient sociodemographic and clinical characteristics.

RESULTS

One hundred eighteen hospitals transferred 3,197 emergency general surgery patients over the 2-year study period; 1,131 experienced in-hospital morbidity, mortality, or extended length of stay (>75th percentile). Patients were 62 years old on average, 50% were female, and 5% were non-White. In the mixed-effects model, hospitals' proportion of patients shared was associated with lower odds of an in-hospital complication; specifically, when the proportion of patients shared between two hospitals doubled, the relative odds of any outcome changed by 0.85.

CONCLUSION

Our results suggest the importance of emergent relationships between hospital dyads that share patients in quality outcomes. Transfer protocols should account for established efficiencies, familiarity, and coordination between hospitals.

Impact of COVID-19 on common non-elective general surgery diagnoses

BACKGROUND

During the COVID-19 pandemic, public health and hospital policies were enacted to decrease virus transmission and increase hospital capacity. Our aim was to understand the association between COVID-19 positivity rates and patient presentation with EGS diagnoses during the COVID pandemic compared to historical controls.

METHODS

In this cohort study, we identified patients ≥ 18 years who presented to an urgent care, freestanding ED, or acute care hospital in a regional health system with selected EGS diagnoses during the pandemic (March 17, 2020 to February 17, 2021) and compared them to a pre-pandemic cohort (March 17, 2019 to February 17, 2020). Outcomes of interest were number of EGS-related visits per month, length of stay (LOS), 30-day mortality and 30-day readmission.

RESULTS

There were 7908 patients in the pre-pandemic and 6771 in the pandemic cohort. The most common diagnoses in both were diverticulitis (29.6%), small bowel obstruction (28.8%), and appendicitis (20.8%). The lowest relative volume of EGS patients was seen in the first two months of the pandemic period (29% and 40% decrease). A higher percentage of patients were managed at a freestanding ED (9.6% vs. 8.1%) and patients who were admitted were more likely to be managed at a smaller hospital during the pandemic. Rates of surgical intervention were not different. There was no difference in use of ICU, ventilator requirement, or LOS. Higher 30-day readmission and lower 30-day mortality were seen in the pandemic cohort.

CONCLUSIONS

In the setting of the COVID pandemic, there was a decrease in visits with EGS diagnoses. The increase in visits managed at freestanding ED may reflect resources dedicated to supporting outpatient non-operative management and lack of bed availability during COVID surges. There was no evidence of a rebound in EGS case volume or substantial increase in severity of disease after a surge declined.

Cost Differences Between Teaching and Nonteaching Hospitals for Older Adults Requiring Emergency General Surgery Procedures in the State of Maryland

BACKGROUND

Older adults (OAs; ≥ 65 years) comprise a growing population in the United States and are anticipated to require an increasing number of emergency general surgery procedures (EGSPs). The aims of this study were to identify the frequency of EGSPs and compare cost of care in OAs managed at teaching hospitals (THs) vs nonteaching hospitals (NTHs).

METHODS

A retrospective review of data from the Maryland Health Services Cost Review Commission database from 2009 to 2018 for OAs undergoing EGSPs was undertaken. Data collected included demographics, all patient-refined (APR)-severity of illness (SOI), APR-risk of mortality (ROM), Charlson Comorbidity Index (CCI), EGSPs (partial colectomy (PC), small bowel resection, cholecystectomy, operative management of peptic ulcers, lysis of adhesions, appendectomy, and laparotomy, categorized hospital charges, length of stay (LOS), and mortality.

RESULTS

Of the 55,401 OAs undergoing EGSPs in this study, 28,575 (51.6%) were treated at THs and 26,826 (48.4%) at NTHs. OAs at THs presented with greater APR-ROM (major 25.6% vs 24.9%, extreme 22.6% vs 22.0%, P=.01), and CCI (3.1±3 vs 2.7±2.8, P<.001) compared to NTHs. Lysis of adhesions, cholecystectomy, and PC comprised the overall most common EGSPs. Older adults at THs incurred comparatively higher median hospital charges for every EGSP due to increased room charges and LOS. Mortality was higher at THs (6.13% vs 5.33%, P<.001).

CONCLUSION

While acuity of illness appears similar, cost of undergoing EGSPs for OAs is higher in THs vs NTHs due to increased LOS. Future work is warranted to determine and mitigate factors that increase LOS at THs.
