Factors associated with Interhospital transfers of emergency general surgery patients from emergency departments

A National Analysis of Racial and Sex Disparities Among Interhospital Transfers for Emergency General Surgery Patients and Associated Outcomes

INTRODUCTION

Studies focusing on Emergency General Surgery (EGS) and Interhospital Transfer (IHT) and the association of race and sex and morbidity and mortality are yet to be conducted. We aim to investigate the association of race and sex and outcomes among IHT patients who underwent emergency general surgery.

METHODS

A retrospective review of adult patients who were transferred prior to EGS procedures using the National Surgery Quality Improvement Project from 2014 to 2020. Multivariable logistic regression models were used to compare outcomes (readmission, major and minor postoperative complications, and reoperation) between interhospital transfer and direct admit patients and to investigate the association of race and sex for adverse outcomes for all EGS procedures. A secondary analysis was performed for each individual EGS procedure.

RESULTS

Compared to patients transferred directly from home, IHT patients (n = 28,517) had higher odds of readmission [odds ratio (OR): 1.004, 95% confidence interval (CI) (1.002-1.006), P < 0.001], major complication [adjusted OR: 1.119, 95% CI (1.117-1.121), P < 0.001), minor complication [OR: 1.078, 95% CI (1.075-1.080), P < 0.001], and reoperation [OR: 1.014, 95% CI (1.013-1.015), P < 0.001]. In all EGS procedures, Black patients had greater odds of minor complication [OR 1.041, 95% CI (1.023-1.060), P < 0.001], Native Hawaiian and Pacific Islander patients had greater odds of readmission [OR 1.081, 95% CI (1.008-1.160), P = 0.030], while Asian and Hispanic patients had lower odds of adverse outcome, and female patients had greater odds of minor complication [OR 1.017, 95% CI (1.008-1.027), P < 0.001].

CONCLUSIONS

Procedure-specific racial and sex-related disparities exist in emergency general surgery patients who underwent interhospital transfer. Specific interventions should be implemented to address these disparities to improve the safety of emergency procedures.

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.

Racial and ethnic disparities in interhospital transfer for complex emergency general surgical disease across the United States

BACKGROUND

Differential access to specialty surgical care can drive health care disparities, and interhospital transfer (IHT) is one mechanism through which access barriers can be realized for vulnerable populations. The association between race/ethnicity and IHT for patients presenting with complex emergency general surgery (EGS) disease is understudied.

METHODS

Using the 2019 Nationwide Emergency Department Sample, we identified patients 18 years and older with 1 of 13 complex EGS diseases based on International Classification of Diseases, Tenth Revision , diagnosis codes. The primary outcome was IHT. A series of weighted logistic regression models was created to determine the association of race/ethnicity with the primary outcome while controlling for patient and hospital characteristics.

RESULTS

Of 387,610 weighted patient encounters from 989 hospitals, 59,395 patients (15.3%) underwent IHT. Compared with non-Hispanic White patients, rates of IHT were significantly lower for non-Hispanic Black (15% vs. 17%; unadjusted odds ratio (uOR) [95% confidence interval (CI)], 0.58 [0.49-0.68]; p < 0.001), Hispanic/Latinx (HL) (9.0% vs. 17%; uOR [95% CI], 0.48 [0.43-0.54]; p < 0.001), Asian/Pacific Islander (Asian/PI) (11% vs. 17%; uOR [95% CI], 0.84 [0.78-0.91]; p < 0.001), and other race/ethnicity (12% vs. 17%; uOR [95% CI], 0.68 [0.57-0.81]; p < 0.001) patients. In multivariable models, the adjusted odds of IHT remained significantly lower for HL (adjusted odds ratio [95% CI], 0.76 [0.72-0.83]; p < 0.001) and Asian/PI patients (adjusted odds ratio [95% CI], 0.73 [0.62-0.86]; p < 0.001) but not for non-Hispanic Black and other race/ethnicity patients ( p > 0.05).

CONCLUSION

In a nationally representative sample of emergency departments across the United States, patients of minority race/ethnicity presenting with complex EGS disease were less likely to undergo IHT when compared with non-Hispanic White patients. Disparities persisted for HL and Asian/PI patients when controlling for comorbid conditions, hospital and residential geography, neighborhood socioeconomic status, and insurance; these patients may face unique barriers in accessing surgical care.

Impact of interhospital transfer on emergency department timeliness of care and in-hospital outcomes of adult non-trauma patients

Background

Patients who present to the emergency department (ED) from interhospital transfer (IHT) and non-IHT are known to have differences in various clinical outcomes including mortality. The ED timeliness of care is an effective indicator of the quality of ED care and operational efficiency. The impact of IHT on ED timeliness of care remains unclear. We evaluated the association between IHT and ED timeliness of care or in-hospital outcomes in adult non-trauma patients.

Methods

Data of consecutive hospital admission of adult non-trauma patients who visited the ED of a medical center from January 2018 to Jun 2020 were retrospectively analyzed. The patients were divided into IHT and non-IHT cohorts. Various data were recorded. The ED length of stay (LOS) was measured as the outcome of ED timeliness of care, while hospital LOS and in-hospital death were measured as the in-hospital outcomes. Multiple regression analyses were performed using unmatched and propensity-matched cohorts. In the later analyses, both groups were propensity matched for sex, age, and other covariates that showed significant differences between two groups to achieve a 1:4 balanced cohort.

Results

Data on 1856 IHT patients and 16295 non-IHT patients were analyzed. IHT was associated with a shorter ED LOS, longer hospital LOS, and higher odds of in-hospital death compared with non-IHT in unmatched and propensity-matched analyses. The shorter ED LOS was due to the slightly longer interval of arrival to ED physicians (∼1 min) and considerably shorter intervals of ED physicians to decision (∼120 min) and decision to departure (∼105 min). Risk stratification revealed that IHT was associated with a shorter ED LOS in patients with all levels (1-5) of Taiwan Triage and Acuity Scale (TTAS) and associated with longer hospital LOS and higher odds of in-hospital death in patients with TTAS level ≥3.

Conclusions

IHT was associated with a shorter ED LOS, longer hospital LOS, and higher odds of in-hospital death in adult non-trauma patients compared with non-IHT. The expedited ED timeliness of care in the IHT cohort was due to considerably shorter intervals of both ED physicians to decision and decision to disposition.

Impact of inter-hospital transfer on outcomes of urgent cholecystectomy

BACKGROUND

This study used a national cohort to characterize the impact of inter-hospital transfer status on outcomes following nonelective cholecystectomy for cholecystitis.

METHODS

Nonelective cholecystectomies were identified using the 2016-2019 National Inpatient Sample. Multivariable models adjusting for patient and hospital characteristics were utilized to assess outcomes of interest.

RESULTS

Of an estimated 530,696 patients, 5.3% were transferred. Transferred patients were older, more often male, and more likely to report income in the 0^th-25th percentile, compared to others. After adjustment, transfer was associated with increased odds of infectious complications (AOR 1.31, 95%CI 1.06-1.60) and non-home discharge (AOR 1.59, 95%CI 1.45-1.74), but not mortality. Transfer was linked to a $600 cost decrement at the operating hospital (95%CI -$880-330).

CONCLUSIONS

Transfer status is associated with greater postoperative infection, but not mortality. Given that disparities may play a role in transfer decisions, more work must be done to identify transfer drivers and improve patient outcomes.

Where to next? An exploration of patients with disability and complex needs who leave acute care hospitals via an interim discharge pathway

ObjectiveTo examine the characteristics and circumstances of admitted patients with disability who require individualised supports to leave hospital and who experience interim discharge arrangements.MethodsThe study used a retrospective exploratory design. Medical chart reviews of patients with disability who required funded support to leave hospital were conducted. The records of 224 patients admitted to one of three hospital facilities in South-East Queensland, Australia, between May 2017 and January 2020 were reviewed. Information about hospital facility, demographic characteristics, disability type, support needs, discharge destination, and reasons for interim discharges were extracted for analysis.ResultsForty of 224 patients were discharged to an interim destination. Inter-hospital transfers were the most common interim discharge arrangement. Being divorced or separated was the only demographic variable associated with having an interim discharge arrangement for admitted patients with disability. More patients with disability who experienced an interim discharge required accommodation supports and behavioural supports compared to patients who were not involved in interim discharges.ConclusionsPatients with disability with minimal informal support and who rely on a sophisticated mix of individualised supports to leave hospital may be more susceptible to interim discharge arrangements. Early identification of these patients and formal mechanisms for ensuring continuous coordination of ongoing transitions and supports is critical to avoid sub-optimal outcomes. Future research is needed to capture a complete picture of the series of transitions of interim discharged patients with disability leaving acute care facilities and the quality of their supports and outcomes.

Factors influencing interhospital transfer delays in emergency general surgery: a systematic review and narrative synthesis

BACKGROUND

Emergency general surgery is an emerging public health issue globally, with substantial healthcare burden. Interhospital transfer of critically unwell surgical patients has been the mainstay of bridging gaps in surgical coverage in regional and rural locations, despite evidence of greater morbidity and mortality. Delays in transfer invariably occurs and compounds the situation. Our aim was to examine the factors influencing interhospital transfer delays in emergency general surgical patients.

METHODS

A systematic search of PubMED and EmBase, was performed by two researchers from 2020 to 23rd Feb 2021, for English articles related to interhospital transfer delays in emergency general surgical patients, with an age of >16. Articles were critically appraised and data were extracted into a pre-specified data extraction form. No data was suitable for statistical analysis and a narrative synthesis was performed instead.

RESULTS

Six relevant articles were identified from the search. All studies were retrospective cohort studies with moderate to high risk of bias. Lack of consultant surgeon input, after hours transfer, need for intensive care bed and poor transfer documentation may have a role in interhospital transfer delays. Patients with public health insurance, multiple comorbidities and non-emergency medical conditions experience longer transfer request time and may be at risk of precipitating interhospital transfer delays. Transfer delays are seen in transfers over longer distances.

CONCLUSION

There is a paucity of knowledge on what and how factors influence interhospital transfer delays in emergency general surgical patients. Well-designed prospective cohort studies are required to bridge this knowledge gap.

Predictors of interhospital transfer delays in acute surgical patient deaths in Australia: a retrospective study

BACKGROUND

Interhospital transfers in Australia facilitate access to acute surgical services, however transfer delays can occur. The aims of this study were to examine Australian mortality audit data on acute surgical patients who were transferred after presenting with a surgical emergency, and to identify modifiable predictors of transfer delay.

METHODS

Surgical admissions between 1 January 2001 and 18 August 2020 were retrospectively extracted from the Australian and New Zealand Audit of Surgical Mortality database. Relevant factors and themes of interest were collated. Results were presented as odds ratios (OR) and 95% confidence intervals (CI), with statistical significance defined as P <0.05.

RESULTS

After exclusion, a final 8270 cases were analysed. Non-modifiable predictors identified were female gender (OR 1.34, 95% CI 1.05-1.70, P = 0.0184), comorbidities (OR 1.50, 95% CI 1.40-161, P <0.0001) and major non-trauma non-vascular specialty (OR 1.54 to 7.77, depending on specialty, P < 0.05). Modifiable predictors were inadequate clinical assessment (OR 49.48, 95% CI 32.91-74.38, P <0.0001), poor communication (OR 6.62, 95% CI 3.70-11.85, P <0.0001) and multiple transfers (OR 6.30, OR 95% 4.31-9.21, P <0.0001). Age, lack of bed and after-hours transfer did not predict transfer delays. Metropolitan transfers was protective against transfer delays (OR 0.64, 95% CI 0.47-0.86, P = 0.0035).

CONCLUSION

In the view of the receiving surgeon or assessor, all transfer delays potentially contributed to patient deaths, and may have been preventable. Strategies directed at modifiable factors could minimize delays. Increased surgical services in non-metropolitan regions could reduce need for transfer. Prospective data is required to examine if the same predictors are observed in surgical patients who survive.

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.
