Cost Burden and Mortality in Rural Emergency General Surgery Transfer Patients

Impact of Tele-Triage Pathways on Short-Stay Admission after Transfer to a Regional Burn Center for Acute Burn Injury

BACKGROUND

Regionalized care for burn-injured patients requires accurate triage. In 2016, we implemented a tele-triage system for acute burn consultations. We evaluated resource utilization following implementation, hypothesizing that this system would reduce short-stay admissions and prioritize inpatient care for those with higher burn severity.

STUDY DESIGN

We conducted a retrospective study of all transferred patients with acute burn injuries from January 1, 2010 to December 31, 2015, and January 1, 2017 to December 31, 2019. We evaluated the proportions of short-stay admissions (discharges less than 24 hours without operative intervention, ICU admission, or concern for nonaccidental trauma) among patients transferred before (2010 to 2015) and after (2017 to 2019) triage system implementation. Multivariable Poisson regression was used to evaluate factors associated with short-stay admissions. Interrupted time series analysis was used to evaluate the effect of the triage system.

RESULTS

There were 4,688 burn transfers (3,244 preimplementation and 1,444 postimplementation) in the study periods. Mean age was higher postimplementation (32 vs 29 years, p < 0.001). Median hospital length of stay (LOS) and ICU LOS were both 1 day higher, more patients underwent operative intervention (19% vs 16%), and median time to first operation was 1 day lower postimplementation. Short-stay admissions decreased from 50% (n = 1,624) to 39% (n = 561), and patients were 17% less likely to have a short-stay admission after implementation (adjusted relative risk [aRR], 0.83; 95% CI, 0.8 to 0.9). Pediatric patients younger than 15 years old composed 43% of all short-stay admissions and were much more likely than adult patients to have a short-stay admission independent of transfer timing (aRR, 2.36; 95% CI, 1.84 to 3.03).

CONCLUSIONS

Tele-triage burn transfer center protocols reduced short-stay admissions and prioritized inpatient care for patients with more severe injuries. Pediatric patients remain more likely to have short-stay admission after transfer.

Emergency General Surgery Transfers to Definitive Care: An Assessment of Patient and Systemic Factors in Appendicitis Referrals

Patients presenting to the emergency department (ED) with an Emergency General Surgery (EGS) problem often require transfer to a tertiary facility. Issues impacting EGS mirror the same issues trauma surgery faced prior to the implementation of current trauma guidelines. This study analyzed the cost, time, and transport resource utilization of EGS patients with acute appendicitis when transferred from network hospitals to a level II trauma center. This was a retrospective study. Patients were transferred by a critical or specialty care transport team 62% of the time, although no skills performed required a critical or specialty care provider. The median time from decision to transfer to incision was 254 minutes, with an average transport time of 27 minutes. This study suggests that there is an opportunity to improve access to the operating room and to decrease resource utilization of specialty care and critical care transport for patients.

Complexity of Transferred Geriatric Adults Requiring Emergency General Surgery: A Rural Tertiary Center Experience

INTRODUCTION

As the American population ages, the number of geriatric adults requiring emergency general surgery (EGS) care is increasing. EGS regionalization could significantly affect the pattern of care for rural older adults. The aim of this study was to determine the current pattern of care for geriatric EGS patients at our rural academic center, with a focus on transfer status.

MATERIALS AND METHODS

We performed a retrospective chart review of patients aged ≥65 undergoing EGS procedures within 48 h of admission from 2014 to 2019 at our rural academic medical center. We collected demographic, admission, operative, and outcomes data. The primary outcomes of interest were mortality and nonhome discharge. Univariate and multivariate analyses were performed.

RESULTS

Over the 5-y study period, 674 patients underwent EGS procedures, with 407 (60%) transferred to our facility. Transfer patients (TPs) had higher American Society of Anesthesiology (ASA) scores (P < 0.001), higher rates of open abdomen (13% versus 5.6%, P = 0.001), and multiple operations (24 versus 11%, P < 0.001) than direct admit patients. However, after adjustment there was no difference in mortality (OR 1.64; 95% CI, 0.82-3.38) or nonhome discharge (OR 1.49; 95% CI, 0.95-2.36).

CONCLUSIONS

At our institution, the majority of rural geriatric EGS patients were transferred from another hospital for care. These patients had higher medical and operative complexity than patients presenting directly to our facility for care. After adjustment, transfer status was not independently associated with in-hospital mortality or nonhome discharge. These patients were appropriately transferred given their level of complexity.

Documenting surgical triage in rural surgical networks: Formalising existing structures

OBJECTIVE

It is essential that the embedded process of rural case selection be highlighted and documented to provide reassurance of rigour across rural surgical services supported by generalist surgeons, general practitioners with enhanced surgical skills and general practitioner anaesthetists. This enables feedback and improves the triage and case selection process to ensure the highest quality outcomes. Therefore, this research aims to explore participants' rational criteria for decision making around rural case selection.

DESIGN

Participants participated in a series of semi-structured in-depth interviews which were coded and underwent thematic analysis.

SETTING

Six community hospitals in British Columbia, Canada.

PARTICIPANTS

General practitioners with enhanced surgical skills, general practitioner anaesthetists, local maternity care providers, and specialists.

RESULTS

Based on participant accounts, rural surgical and obstetrical decision-making processes for local patient selection or regional referral had five major components: (1) Clinical Factors, (2) Physician Factors, (3) Patient Factors, (4) Consensus Between Providers and (5) the Availability of Local Resources.

CONCLUSION

Decision-making processes around rural surgical and obstetrical patient selection are complex and require comprehensive understanding of local capacity and resources. Current policies and guidelines fail to consider the varying capacities of each rural site and should be hospital specific.

Emergency General Surgery Quality Improvement: A Review of Recommended Structure and Key Issues

Emergency general surgery (EGS) accounts for 11% of hospital admissions, with more than 3 million admissions per year and more than 50% of operative mortality in the US. Recent research into EGS has ignited multiple quality improvement initiatives, and the process of developing national standards and verification in EGS has been initiated. Such programs for quality improvement in EGS include registry formation, protocol and standards creation, evidenced-based protocols, disease-specific protocol implementation, regional collaboratives, targeting of high-risk procedures such as exploratory laparotomy, focus on special populations like geriatrics, and targeting improvements in high opportunity outcomes such as failure to rescue. The authors present a collective narrative review of advances in quality improvement structure in EGS in recent years and summarize plans for a national EGS registry and American College of Surgeons verification for this under-resourced area of surgery.

High Resource Utilization in Emergent Versus Elective General Surgery

BACKGROUND

In an era of pay for performance metrics, we sought to increase understanding of factors driving high resource utilization (HRU) in emergent (EGS) versus same-day elective (SDGS) general surgery patients.

METHODS

General surgery procedures from the 2016 ACS-NSQIP public use file were grouped according to the first four digits of the primary procedure CPT code. Groups having at least 100 of both elective and emergent cases were included (22 groups; 83,872 cases). HRU patients were defined as those in-hospital >7D, returned to the OR, readmitted, and/or had morbidity likely requiring an intensive care unit (ICU)stay. Independent NSQIP predictors of HRU were identified through forward regression; P for entry < 0.05, for exit > 0.10.

RESULTS

Of all patients, 33% were HRU. The three highest HRU procedures (total colectomy, enterolysis, and ileostomy) comprised a higher proportion of EGS than SDGS cases (10.3 versus 2.6%, P < 0.001). The duration of operation was 40 Min lower in EGS after adjustment. Thirty-nine of the remaining 40 HRU predictors were higher in EGS including preoperative SIRS/Sepsis (50 versus 2%), ASA classification IV-V (31 versus 5%), albumin <3.5 g/dL (40 versus 12%), transfers (26 versus 2%, P's < 0.001), septuagenarians (35 versus 25%) and disseminated cancer (6.3 versus 4.8%, P's < 0.001); while sex did not differ. After adjustment, EGS patients remained more likely to be HRU (odds ratio 2.5, 95% CI 2.4 - 2.6, P < 0.001).

CONCLUSIONS

EGS patients utilize significantly more resources than SDGS patients above what can be adjusted for in the clinically robust ACS-NSQIP dataset. Distinctive payment and value-based performance models are necessary for EGS.

Transfer Status and 90-Day Mortality in ICU Patients with Sepsis: A Propensity Matched Analysis

BACKGROUND

Timely identification and management of sepsis in surgical patients is crucial, and transfer status may delay optimal treatment of these patients. The objective of this study was to compare in-house and 90-day mortality between patients primarily admitted or transferred into the surgical ICU (SICU) at a tertiary referral center.

MATERIAL AND METHODS

All patients admitted to the SICU with a diagnosis of sepsis (Sepsis III) were reviewed at a single institution between 2014 to 2019 (n = 1489). Demographics, comorbidities, and sepsis presentation were compared between transferred (n = 696) and primary patients (n = 793). Primary outcomes evaluated were in-house and 90 day mortality in an unmatched and propensity score matched cohorts. A P value < 0.05 was considered statistically significant.

RESULTS

Transfer patients were more likely to have obesity (60% versus 49%, P < 0.005), a higher median SOFA (6 (4-8) versus 5 (3-8), P = 0.007), and require vasopressors on admission (42% versus 35%, P = 0.004). Compared to primary patients, transfer patients exhibited higher rates of respiratory failure (76% versus 69%, P = 0.003), in-house (30% versus 17%, P < 0.005), and 90 day mortality (36% versus 24%, P < 0.005). After matching, transferred patients were associated with 75% and 83% increased odds of in-house and 90 day mortality after controlling for age, sex, race, comorbidities, BMI, and sepsis severity.

CONCLUSIONS

Transfer status is associated with an over 80% increase in the odds of 90 day mortality for patients admitted to the SICU with sepsis. Aggressive patient identification and earlier transfer of those at higher risk of death may reduce this effect.

Geographic Variation in Appendiceal Perforation Rates in Canada: a Population-Based Cohort Study

BACKGROUND

We hypothesized that patients living in rural neighborhoods experience delayed access to surgical services manifesting in increased appendiceal perforation rates in cases of appendicitis.

METHODS

This population-based cohort study included adult patients with acute appendicitis in Canada (excluding Quebec) between April 2008 and March 2015. The main outcome of interest was rate of perforation. Predictors of interest included socioeconomic, geographic, and individual predictors of perforation. Spatial analysis was used to analyze spatial clustering of perforation.

RESULTS

We identified 143,195 patients throughout the course of the study. The average perforation rate across our study was 35.9% (n = 51,456). Cluster analysis identified 286 (24%) neighborhoods with perforation rates greater than the average. Rural neighborhoods had a 1.89 times higher odds of being in a high perforation cluster (95% CI 1.08-3.08, p = 0.024). Compared to neighborhoods > 75 km from the admitting hospital, closer neighborhoods were less likely to be in a high perforation cluster (0-35 km OR 0.64, 95% CI 0.38-0.98, p = 0.049; 36-75 km OR 0.60, 95% CI 0.37-0.92, p = 0.019). Patients admitted to small community hospitals had a 0.51 times lower odds of perforation than those admitted to academic centers (95% CI 0.47-0.54, p < 0.001) and those who lived in high perforation clusters had a 1.42 times higher odds of perforation (95% CI 1.39-1.46, p < 0.001).

CONCLUSION

Neighborhoods located far from hospitals have increased appendiceal perforation rates. Also, patients with appendicitis treated at small community hospitals have significantly lower odds of perforation. From a policy point of view, patients with symptoms of appendicitis can be safely treated at the nearest hospital.

An evaluation of emergency general surgery transfers and a call for standardization of practices

BACKGROUND

There is an increasing trend toward regionalization of emergency general surgery, which burdens patients. The absence of a standardized, emergency general surgery transfer algorithm creates the potential for unnecessary transfers. The aim of this study was to evaluate clinical reasoning prompting emergency general surgery transfers and to initiate a discussion for optimal emergency general surgery use.

METHODS

Consecutive emergency general surgery transfers (December 2018 to May 2019) to 2 tertiary centers were prospectively enrolled in an institutional review board-approved protocol. Clinical reasoning prompting transfer was obtained prospectively from the accepting/consulting surgeon. Patient outcomes were used to create an algorithm for emergency general surgery transfer.

RESULTS

Two hundred emergency general surgery transfers (49% admissions, 51% consults) occurred with a median age of 59 (18 to 100) and body mass index of 30 (15 to 75). Insurance status was 25% private, 45% Medicare, 21% Medicaid, and 9% uninsured. Weekend transfers (Friday to Sunday) occurred in 45%, and 57% occurred overnight (6:00 pm to 6:00 am). Surgeon-to-surgeon communication occurred with 22% of admissions. Pretransfer notification occurred with 10% of consults. Common transfer reasons included no surgical coverage (20%), surgeon discomfort (24%), or hospital limitations (36%). A minority (36%) underwent surgery within 24 hours; 54% did not require surgery during the admission. Median length of stay was 6 (1 to 44) days.

CONCLUSION

Conditions prompting emergency general surgery transfers are heterogeneous in this rural state review. There remains an unmet need to standardize emergency general surgery transfer criteria, incorporating patient and hospital factors and surgeon availability. Well-defined requirements for communication with the accepting surgeon may prevent unnecessary transfers and maximize resource allocation.
