Under-triage of severely injured patients presenting to non-trauma centers (failure to transfer to a trauma center) remains problematic despite quality improvement efforts. Insights from the ...behavioral science literature suggest that physician heuristics (intuitive judgments), and in particular the representativeness heuristic (pattern recognition), may contribute to under-triage. However, little is known about how the representativeness heuristic is instantiated in practice.
A multi-disciplinary group of experts identified candidate characteristics of "representative" severe trauma cases (e.g., hypotension). We then reviewed the charts of patients with moderate-to-severe injuries who presented to nine non-trauma centers in western Pennsylvania from 2010-2014 to assess the association between the presence of those characteristics and triage decisions. We tested bivariate associations using χ2 and Fisher's Exact method and multivariate associations using random effects logistic regression.
We identified 235,605 injured patients with 3,199 patients (1%) having moderate-to-severe injuries. Patients had a median age of 78 years (SD 20.1) and mean Injury Severity Score of 10.9 (SD 3.3). Only 759 of these patients (24%) were transferred to a trauma center as recommended by the American College of Surgeons clinical practice guidelines. Representative characteristics occurred in 704 patients (22%). The adjusted odds of transfer were higher in the presence of representative characteristics compared to when they were absent (aOR 1.7, 95% CI: 1.4-2.0, p < 0.001).
Most moderate-to-severely injured patients present without the characteristics representative of severe trauma. Presence of these characteristics is associated with appropriate transfer, suggesting that modifying physicians' heuristics in trauma may improve triage patterns.
Injury to the inferior vena cava (IVC) can produce bleeding that is difficult to control. Endovascular balloon occlusion provides rapid vascular control without extensive dissection and may be useful ...in large venous injuries, especially in the juxtarenal IVC. We describe the procedural steps, technical considerations, and clinical scenarios for using the Bridge occlusion balloon (Philips) in IVC trauma. We present a single-center case series of 5 patients in which endovascular balloon occlusion of the IVC was used for hemorrhage control. All 5 patients were men (median age 35, range 22 to 42 years). They all sustained penetrating injuries-4 gunshot wounds and 1 stab wound. Median presenting Shock Index was 0.7 (range 0.5 to 1.5). Median initial lactate was 5.4 mmol/L (range 4.6 to 6.9 mmol/L). There were 2 suprarenal IVC injuries, 2 juxtarenal injuries, and 3 infrarenal injuries. Four patients underwent primary repair of their injury, and one underwent IVC ligation. Four patients had intraoperative Resuscitative Endovascular Balloon Occlusion of the Aorta for inflow control and afterload support. The median number of total blood products transfused during the initial operation was 37 units (range 16 to 77 units). Four patients underwent damage control operations, and one patient had a single definitive operation. Four of the 5 patients (80%) survived to discharge with the lone mortality being due to other injuries. Endovascular balloon occlusion serves as a valuable adjunct in the management of IVC injury and demonstrates the potential of hybrid open-endovascular operative techniques in abdominal vascular trauma.
Perforated peptic ulcer is a morbid emergency general surgery condition. Best practices for postoperative care remain undefined. Surgical dogma preaches practices such as peritoneal drain placement, ...prolonged nil per os, and routine postoperative enteral contrast imaging despite a lack of evidence. We aimed to evaluate the role of postoperative enteral contrast imaging in postoperative perforated peptic ulcer care. Our primary objective was to assess effects of routine postoperative enteral contrast imaging on early detection of clinically significant leaks.
We conducted a multicenter retrospective cohort study of patients who underwent repair of perforated peptic ulcer between July 2016 and June 2018. We compared outcomes between those who underwent routine postoperative enteral contrast imaging and those who did not.
Our analysis included 95 patients who underwent primary/omental patch repair. The mean age was 60 years, and 54% were male. Thirteen (14%) had a leak. Eighty percent of patients had a drain placed. Nine patients had leaks diagnosed based on bilious drain output without routine postoperative enteral contrast imaging. Use of routine postoperative enteral contrast imaging varied significantly between institutions (30%–87%). Two late leaks after initial normal postoperative enteral contrast imaging were confirmed by imaging after a clinical change triggered the second study. Two patients had contained leaks identified by routine postoperative enteral contrast imaging but remained clinically well. Duration of hospital stay was longer in those who received routine postoperative enteral contrast imaging (12 vs 6 days, median; P = .000).
Routine postoperative enteral contrast imaging after perforated peptic ulcer repair likely does not improve the detection of clinically significant leaks and is associated with increased duration of hospital stay.
A majority of severely injured patients fail to receive care at trauma centers (undertriage), in part, because of physician judgment. We previously developed two educational video games that reduced ...physicians' undertriage compared with control in two clinical trials. In this secondary analysis, we investigated heterogeneity of treatment effect of the interventions by assessing physicians' preexisting practice patterns in claims data. We hypothesized that physicians with high preexisting undertriage would benefit most from game-based training.
Using Medicare claims records from 2010 to 2015, we measured physicians' preexisting triage practices before their participation in one of two trials conducted in 2016 and 2017. We categorized physicians as having received game-based training versus control and noted their postintervention simulation triage performance in the trials. We used multivariable linear regression models to assess the heterogeneity of game-based training effect among physicians with high and low preexisting undertriage.
Of the 394 eligible physicians from our trials, we identified 275 (70%) with claims for Medicare fee-for-service beneficiaries suffering severe injury between 2010 and 2015. On average, the physicians were 44 y old (SD 8.4) with 12 y (SD 8.2) of experience. We found significant interaction between preexisting practice and intervention efficacy (P = 0.04). Physicians with high undertriage before enrollment improved significantly with game-based training compared with the control (46% versus 63%, P < 0.001). Those with low preexisting undertriage did not (58% versus 56%, P = 0.76).
Using claims-based data, we found heterogeneity of treatment effect of interventions designed to recalibrate physician heuristics. Physicians with high preexisting undertriage benefited most from game-based training.
The rising incidence of liver disease has complicated the management of common surgical pathologies. Hernias, in particular, are problematic given the shortage of high-quality data and differing ...expert opinions. We aim to provide a narrative review of hernia management in cirrhosis as a first step toward developing evidence-based recommendations for the care of these patients.
A literature review using separate search strings was conducted for PubMed and Cochrane Central Register of Controlled Trials databases. Review articles, conference abstracts, randomized clinical trials, and observational studies were included. Articles without a focus on patients with end-stage liver disease were excluded. Manuscripts were selected based on relevance to perioperative risk assessment, medical optimization, surgical decision-making, and considerations of hernia repair in patients with cirrhosis.
The existing literature is varied with regard to focus and quality of data. Of the 4516 articles identified, 51 full-text articles were selected for review. In general, there is evidence to suggest that individuals with compensated cirrhosis may successfully undergo and benefit from hernia repair. Patients at high risk for decompensated cirrhosis may be best served by nonoperative management.
Carefully selected patients with cirrhosis may proceed with herniorrhaphy. A multidisciplinary approach is essential to provide high-quality care and improve outcomes.
Multiple studies have shown the significantly increased post-operative morbidity and mortality of patients undergoing palliative operations. It has been proposed by some authors that the American ...College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database can be used reliably to develop risk-calculators or as an aid for clinical decision-making in advanced cancer patients. ACS-NSQIP is a population-based database that by design only captures outcomes data for the first 30-day following an operation. We considered the suitability of these data as a tool for decision-making in the advanced cancer patient.
Six-year retrospective review of a single institution's ACS-NSQIP database for cases identified as "Disseminated Cancer". Procedures performed with palliative intent were identified and analyzed.
Of 7,763 patients within the ACS-NSQIP database, 138 (1.8%) were identified as having "Disseminated Cancer". Of the remaining 7,625 entries only 4,486 contained complete survival data for analysis. Thirty-day mortality within the "Disseminated Cancer" group was higher when compared to all other surgical patients (7.9% vs. 0.9%, P<0.001). Explicit chart review of these 138 patients revealed that 32 (23.2%) had undergone operations with palliative intent. Overall survival for palliative and non-palliative operations was significantly different (104 vs. 709 days, P<0.001). When comparing palliative to non-palliative procedures using ACS-NSQIP data, we were unable to detect a difference in 30-day mortality (9.4% vs. 7.5%, P=0.72).
Calculations utilizing ACS-NSQIP data fail to demonstrate the increased mortality associated with palliative operations. Patients diagnosed with advanced cancer are not adequately represented within the database due to the limited number of cases collected. Also, more suitable outcomes measures for palliative operations such as pain relief, functional status, and quality of life, are not captured. Therefore, the sole use of thirty-day morbidity and mortality data contained in the ACS-NSQIP database is insufficient to make sound decisions for surgical palliation.
