Acute Care Surgery Program: Mentoring Fellows and Patient Outcomes

The Impact of Concurrent Multi-Service Coverage on Quality and Safety in Trauma Care

BACKGROUND

At many trauma centers in the United States, one acute care surgeon is responsible for overnight coverage of both the emergency general surgery (EGS) and trauma services. The impact of this scheduling phenomenon on the quality and safety of trauma care has not been studied.

METHODS

Overnight (12:00 AM to 7:00 AM) trauma admissions to an academic Level 1 trauma center from 2013-2015 were studied after the institution adopted this scheduling phenomenon. Admissions were divided into two groups based on whether the admitting surgeon covered only the trauma service, or both the trauma and EGS services ("multi-service coverage"). Four major outcomes (e.g., mortality and complications), six quality metrics (e.g., time to first OR visit and unplanned transfers to the ICU), and procedural utilization patterns were compared.

RESULTS

A total of 1046 admissions were included. There were no differences in any major outcomes between the two exposure groups, including any National Trauma Data Bank-defined complication (OR 1.1, 95% CI 0.8-1.5, P= 0.5). Quality metrics dependent on the admitting surgeon remained unchanged, including attending presence at the highest-level trauma activations within 15 min of arrival (93% versus 86%, P= 0.07) and time to urgent operative intervention (68 min versus 82 min, P= 0.9). There were no differences in the number of laboratory and imaging studies (4.1 versus 4.1, P= 0.9) or bedside interventions (1.8 versus 2.1, P= 0.4) performed per patient by the admitting surgeon. Multivariate logistic regression did not identify multi-service coverage as an independent risk factor for adverse patient outcomes or quality metrics.

CONCLUSIONS

Trauma admissions under a surgeon covering multiple services simultaneously had similar outcomes, quality metrics, and procedural utilization patterns compared to trauma admissions under surgeons covering only the trauma service. Despite concerns that multiple-service coverage may overburden one acute care surgeon, time-dependent quality metrics and studies done during the initial workup of trauma patients remained unchanged. These findings suggest that simultaneous trauma and EGS service coverage by one acute care surgeon does not adversely impact trauma patient care.

Systematic review with meta-analysis of the impact of surgical fellowship training on patient outcomes

Background

The number of surgeons entering fellowship training before independent practice is increasing. This may have a negative impact on surgeons in training. The impact of fellowship training on patient outcomes is not yet known. This review aimed to investigate the impact of fellowship training in surgery on patient outcomes.

Methods

A systematic review of the literature was conducted to identify studies exploring the structural and surgeon-specific characteristics of fellowship training on patient outcomes. Data from these studies were extracted, synthesized and reported qualitatively, or quantitatively through meta-analysis.

Results

Twenty-three studies were included. The mortality rate for patients in centres with an affiliated fellowship programme was lower than that for centres without (odds ratio 0·86, 95 per cent c.i. 0·84 to 0·88), as was the rate of complications (odds ratio 0·90, 0·78 to 1·02). Surgeons without fellowship training converted more laparoscopic operations to open surgery than those with fellowship training (risk ratio (RR) 1·04, 95 per cent c.i. 1·03 to 1·05). Comparison of outcomes for senior surgeons versus current fellows showed no differences in rates of mortality (RR 1·00, 1·00 to 1·01), complications (RR 1·03, 0·98 to 1·08) or conversion to open surgery (RR 1·01, 1·00 to 1·01).

Conclusion

Fellowship training appears to have a positive impact on patient outcomes.

Recommendations for laparoscopic liver resection: a report from the second international consensus conference held in Morioka

The use of laparoscopy for liver surgery is increasing rapidly. The Second International Consensus Conference on Laparoscopic Liver Resections (LLR) was held in Morioka, Japan, from October 4 to 6, 2014 to evaluate the current status of laparoscopic liver surgery and to provide recommendations to aid its future development. Seventeen questions were addressed. The first 7 questions focused on outcomes that reflect the benefits and risks of LLR. These questions were addressed using the Zurich-Danish consensus conference model in which the literature and expert opinion were weighed by a 9-member jury, who evaluated LLR outcomes using GRADE and a list of comparators. The jury also graded LLRs by the Balliol Classification of IDEAL. The jury concluded that MINOR LLRs had become standard practice (IDEAL 3) and that MAJOR liver resections were still innovative procedures in the exploration phase (IDEAL 2b). Continued cautious introduction of MAJOR LLRs was recommended. All of the evidence available for scrutiny was of LOW quality by GRADE, which prompted the recommendation for higher quality evaluative studies. The last 10 questions focused on technical questions and the recommendations were based on literature review and expert panel opinion. Recommendations were made regarding preoperative evaluation, bleeding controls, transection methods, anatomic approaches, and equipment. Both experts and jury recognized the need for a formal structure of education for those interested in performing major laparoscopic LLR because of the steep learning curve.

Nontrauma emergency surgery: optimal case mix for general surgery and acute care surgery training

BACKGROUND

To examine the case mix and patient characteristics and outcomes of the nontrauma emergency (NTE) service in an academic Division of Acute Care Surgery.

METHODS

An NTE service (attending, chief resident, postgraduate year-3 and postgraduate year-2 residents, and two physician assistants) was created in July 2005 for all urgent and emergent inpatient and emergency department general surgery patient consults and admissions. An NTE database was created with prospective data collection of all NTE admissions initiated from November 1, 2007. Prospective data were collected by a dedicated trauma registrar and Acute Physiology and Chronic Health Evaluation-intensive care unit (ICU) coordinator daily. NTE case mix and ICU characteristics were reviewed for the 2-year time period January 1, 2008, through December 31, 2009. During the same time period, trauma operative cases and procedures were examined and compared with the NTE case mix.

RESULTS

Thousand seven hundred eight patients were admitted to the NTE service during this time period (789 in 2008 and 910 in 2009). Surgical intervention was required in 70% of patients admitted to the NTE service. Exploratory laparotomy or laparoscopy was performed in 449 NTE patients, comprising 37% of all surgical procedures. In comparison, only 118 trauma patients (5.9% of admissions) required a major laparotomy or thoracotomy during the same time period. Acuity of illness of NTE patients was high, with a significant portion (13%) of NTE patients requiring ICU admission. NTE patients had higher admission Acute Physiology and Chronic Health Evaluation III scores [61.2 vs. 58.8 (2008); 58.2 vs. 55.8 (2009)], increased mortality [(9.71% vs. 4.89% (2008); 6.78% vs. 5.16% (2009)], and increased readmission rates (15.5% vs. 7.4%) compared with the total surgical ICU (SICU) admissions.

CONCLUSION

In an era of declining operative caseload in trauma, the NTE service provides ample opportunity for complex general surgery decision making and operative procedures for surgical residency education, including advanced surgical critical care management. In addition, creation of an NTE service provides an optimal general surgery case mix, including major abdominal operations, that can augment declining trauma surgery caseloads, maintain acute care faculty surgical skills, and support general and acute care surgery residency training.

Impact of acute care surgery to departmental productivity

BACKGROUND

The face of trauma surgery is rapidly evolving with a paradigm shift toward acute care surgery (ACS). The formal development of ACS has been viewed by some general surgeons as a threat to their practice. We sought to evaluate the impact of a new division of ACS to both departmental productivity and provider satisfaction at a University Level I Trauma Center.

METHODS

Two-year retrospective analysis of annual work relative value unit (wRVU) productivity, operative volume, and FTEs before and after establishment of an ACS division at a University Level I trauma center. Provider satisfaction was measured using a 10-point scale. Analysis completed using Microsoft Excel with a p value less than 0.05 significant.

RESULTS

The change to an ACS model resulted in a 94% increase in total wRVU production (78% evaluation and management, 122% operative; p<0.05) for ACS, whereas general surgery wRVU production increased 8% (-15% evaluation and management, 14% operative; p<0.05). Operative productivity was substantial after transition to ACS, with 129% and 44% increases (p<0.05) in operative and elective case load, respectively. Decline in overall general surgery operative volume was attributed to reduction in emergent cases. Establishment of the ACS model necessitated one additional FTE. Job satisfaction substantially improved with the ACS model while allowing general surgery a more focused practice.

CONCLUSIONS

The ACS practice model significantly enhances provider productivity and job satisfaction when compared with trauma alone. Fears of a productivity impact to the nontrauma general surgeon were not realized.

Does regionalization of acute care surgery decrease mortality?

BACKGROUND

During the initial development of an Emergency General Surgery (EGS) service, severity of illness (SOI) can be expected to be high and should decrease as the service matures. We hypothesize that a matured regional EGS service would show decreasing mortality and length of stay (LOS) over time.

METHODS

We performed a retrospective study of a prospectively collected EGS registry data from 2004 to 2009. Patients were included if they had been discharged from the EGS service and were stratified by year of discharge. Systemic inflammatory response syndrome, sepsis, shock, peritonitis, perforation, and acute renal failure were used as markers of SOI. Patients were defined as high acuity if they had one or more of these SOI markers. Differences in mortality, LOS, intensive care unit admissions, SOI, charges, and distance were compared across and between years using nonparametric statistical tests (Fisher's exact, Wilcoxon rank-sum, and Kruskal-Wallis tests).

RESULTS

A total of 3,439 patients met study criteria. The mean age was 47 years ± 17.5 years. The majority of the patients were female (1,813, 47.3%). The overall LOS was 6.4 days ± 9.4 days (median, 4 days). In all, 2,331 (67.8%) of the patients underwent operation. Over the course of the study period, the SOI indicators stabilized at between 13% and 17% of the patient population with at least one indicator. During that time period, mortality steadily decreased from 4.9% to 1.3% (p < 0.5).

CONCLUSION

Despite consistently high SOI, a dedicated and matured EGS service demonstrated a decrease in mortality and LOS.
