The Economic Effects on Acute Care Surgery in a New York City Public Hospital During the COVID Pandemic.

BACKGROUND: Since the start of the COVID-19 pandemic, less acute care surgical procedures have been performed and consequently hospitals have experienced significant revenue loss. We aim to investigate these procedures performed before and after the start of the COVID-19 pandemic, as well as their effect on the economy. METHODS: This is a retrospective analysis of patients who underwent cholecystectomies and appendectomies during March-May 2019 compared to the same time period in 2020 using Chi-square and t-tests. RESULTS: There were 345 patients who presented with appendicitis or cholecystitis to Elmhurst Hospital Center during the March-May 2019 and 2020 time period. There were three times as many total operations, or about 75%, in 2019 (261) compared to 2020 (84). There was a decrease in the number of admissions from 2019 to 2020 for both acute cholecystitis (149 vs 43, respectively) and acute appendicitis (112 vs 41, respectively). The largest decrease in the number of admissions in 2020 compared to 2019 was observed in April 2020 (98 vs 9, P < .01) followed by May [69 vs 20, P < .01], and March [94 vs 55, P < .01]. Corresponding to the decrease in operative patterns was a noticeable six-time reduction in revenue for the procedures in 2019 ($187,283) compared to 2020 ($30,415). CONCLUSION: We observed almost a triple reduction in the number of cholecystitis and appendicitis procedures performed during the 2020 pandemic surge as compared to the 2019 pre-pandemic data. Elmhurst hospital also experienced four times the loss of revenue during the same time period.

Outcome of Prophylactic Postoperative Negative Pressure Wound Treatment in Colorectal Cancer Patients.

BACKGROUND: Wound infection is a common cause of morbidity in colorectal surgery. We speculated that a prophylactic Negative Pressure Wound Treatment (NPWT) is associated with less postoperative wound complications for colorectal cancer patients who undergo a colectomy. METHODS: Multivariate analysis was used to investigate the association between NPWT and wound complications for patients with colorectal cancer who underwent a colectomy using data from the National Surgical Quality Improvement Program (NSQIP) database during the 2013 - 2019 period. RESULTS: We investigated 96 105 patients who underwent colectomy for colorectal cancer during 2013-2019 within the database. Negative Pressure Wound Treatment was utilized for 270 patients following the principal procedure (.3%). Patients who had NPWT had dirtier wounds, less bowel preparation, more extensive surgery (total colectomy vs partial colectomy), higher stoma creation, and more non-elective operations. Multiple factors were associated with postoperative wound complications such as smoking Adjusted Odd Ratio (AOR:1.27, P < .01), chronic steroid use (AOR: 1.30, P < .01), obesity (AOR: 1.54, P < .01), and serum albumin level less than 3.5 g/dL (AOR: 1.29, P < .01). Overall, there was no significant decrease in wound complications using NPWT (AOR: .66, P = .14). However, a sub-group of patients who underwent emergent/urgent operation had a significant lower risk of wound complications using NPWT (AOR: .3, CI: .09-.99, P = .04). CONCLUSION: Prophylactic NPWT is associated with a decrease in wound complications of patients who underwent an emergent/urgent colectomy for colorectal cancer. However, we could not find any significant decrease in wound complications for elective colorectal procedures for colorectal cancer. Further clinical trials are needed to confirm these study results.

Short Term Outcomes of Open and Minimally Invasive Approaches to Segmental Colectomy for Benign Colovesical Fistula.

Background: We speculated that a minimally invasive (MIS) colectomy for colovesical fistula is associated with less morbidity compared to an open colectomy. Methods: Multivariate analysis using logistic regression was used to investigate the outcomes of patients who underwent colectomy for benign colovesical fistula during 2012-2017 by surgical approach using the NSQIP database. Results: We identified 748 patients underwent partial colectomy for benign colovesical fistula during 2012-2017. Surgeons used the MIS approach in 72.7% of operations, with a conversion rate of 13.1%. The MIS approach was associated with lower morbidity (27.4% vs. 43.1%, AOR: 0.46, P=0.02) compared to the open approach. The mean operation duration was longer in MIS operations compared to open (225 min vs. 201 min, P < 0.01). The robotic approach to colectomy showed no significant difference in morbidity (28.4% vs. 27.2%, P=0.77) but a decrease in conversion rate (8.1% vs. 13.8%, P < 0.01) and an increase in operation length (249 min vs. 222 min, mean difference: 27 min, P < 0.01) compared to a laparoscopic approach. There was no significant difference in the anastomotic leak rate between MIS and open approaches (3.7% vs. 5.4%, P=0.14) and between laparoscopic and robotic approaches (2.8% vs. 3.8%, P=0.99). Conclusions: We found a 72.7% utilization rate of MIS approach to colectomy for benign colovesical fistula in the NSQIP hospitals with a 13.6% conversion rate. Patients with MIS approach had significantly lower morbidity compared to open. A robotic approach to partial colectomy has the same morbidity risk with a decreased conversion rate compared to laparoscopic approach.

Minimally Invasive Surgical Approach to Toxic Colitis.

BACKGROUND: We aimed to compare outcomes of surgical treatments of toxic colitis (infectious/inflammatory/ischemic) by the extent of colectomy (partial vs total colectomy) and different surgical approaches (minimally invasive surgery (MIS) vs open). METHODS: Multivariate analysis using logistic regression was used to investigate outcomes of patients with toxic colitis who underwent emergent colectomy during 2012-2019 by surgical approach and the extent of resection using NSQIP database. RESULTS: Overall, 2,104 adult patients underwent emergent colectomy for toxic colitis within NSQIP database during 2012-2019. Overall, 1,578 (75.4%) underwent total colectomy with colostomy, 486 (23.2%) underwent partial colectomy with colostomy, and 28 (1.3%) underwent partial colectomy with anastomosis. Overall, 198 (9.4%) of procedures were minimally invasive (MIS) with a 40.1% conversion rate to open. Thirty days mortality and morbidity of the patients were 31 and 86%, respectively. There was no significant difference in mortality of partial colectomy without anastomosis compared to total colectomy (P = .86) and partial colectomy with anastomosis (P = .64). Anastomosis was associated with 32.3% anastomosis leakage and 17.9% reoperation. MIS approach was associated with significant decrease in mortality (8.6 vs 33.3%, AOR: .35, P < .01) and morbidity (62.9 vs 87.8%, AOR: .49, P < .01) of patients. CONCLUSION: Patients with toxic colitis undergoing surgical treatment have high mortality and morbidity. An MIS approach when possible is significantly associated with decreased morbidity and mortality of patients. There was no significant difference in outcomes seen when extending the resection in multivariate analysis. Anastomosis is associated with a high anastomosis leakage and need for reoperation risk.

Stop flailing: The impact of bicortically displaced rib fractures on pulmonary outcomes in patients with chest trauma - an American Association for the Surgery of Trauma multi-institutional study.

BACKGROUND: Current evaluation of rib fractures focuses almost exclusively on flail chest with little attention on bicortically displaced fractures. Chest trauma that is severe enough to cause fractures leads to worse outcomes. An association between bicortically displaced rib fractures and pulmonary outcomes would potentially change patient care in the setting of trauma. We tested the hypothesis that bicortically displaced fractures were an important clinical marker for pulmonary outcomes in patients with nonflail rib fractures. METHODS: This nine-center American Association for the Surgery of Trauma multi-institutional study analyzed adults with two or more rib fractures. Admission computerized tomography scans were independently reviewed. The location, degree of rib fractures, and pulmonary contusions were categorized. Univariate and multivariate logistic regression analyses were performed to identify independent predictors of pneumonia, acute respiratory distress syndrome (ARDS), and tracheostomy. Analyses were performed in nonflail patients and also while controlling for flail chest to determine if bicortically displaced fractures were independently associated with outcomes. RESULTS: Of the 1,110 patients, 103 (9.3%) developed pneumonia, 78 (7.0%) required tracheostomy, and 30 (2.7%) developed ARDS. Bicortically displaced fractures were present in 277 (25%) of patients and in 206 (20.3%) of patients without flail chest. After adjusting for patient demographics, injury, and admission physiology, negative pulmonary outcomes occurred over twice as frequently in those with bicortically displaced fractures without flail chest (n = 206) when compared with those without bicortically displaced fractures-pneumonia (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.1-3.6), ARDS (OR, 2.6; 95% CI, 1.0-6.8), and tracheostomy (OR, 2.7; 95% CI, 1.4-5.2). When adjusting for the presence of flail chest, bicortically displaced fractures remained an independent predictor of pneumonia, tracheostomy, and ARDS. CONCLUSION: Patients with bicortically displaced rib fractures are more likely to develop pneumonia, ARDS, and need for tracheostomy even when controlling for flail chest. Future studies should investigate the utility of flail chest management algorithms in patients with bicortically displaced fractures. LEVEL OF EVIDENCE: Prognostic and epidemiological study, level III.

A Novel Risk Score to Predict Post-Trauma Mortality in Nonagenarians.

BACKGROUND: Nonagenarians represent a rapidly growing age group who often have functional limitations and multiple comorbidities, predisposing them to trauma. AIMS: The purpose of this study was to identify patient characteristics, hospital complications, and comorbidities that predict in-hospital mortality in the nonagenarian population following trauma. We also sought to create a scoring system using these variables. SETTINGS AND DESIGN: This study was a retrospective chart review. METHODS: We reviewed the medical records of 548 nonagenarian trauma patients admitted to two Level I trauma centers from 2006 to 2015. Statistical analysis was performed using logistic regression and a machine learning model, which calculated significant variables and computed a scoring system. RESULTS: The in-hospital mortality rate was 7.1% (n = 39). Significant predictors of mortality were cardiac comorbidity, neuro-concussion, New Injury Severity Score (ISS) 16+, striking an object, ISS 25-75, and pulmonary and cardiac complications. Significant variables were assigned a numeric value. A score of 5+ carried a 41.1% mortality risk, 79% sensitivity, and 91% specificity. A score of 10+ had an associated 81.8% mortality risk with 31% specificity and 99% sensitivity. CONCLUSIONS: Our findings identified reliable predictors of mortality in nonagenarian population posttrauma. The scoring system performs with good specificity and sensitivity and incrementally correlates with mortality risk.

A Descriptive Analysis of EtOH Intoxication in our Latino Trauma Patients: An Indication for a Preventive Program.

We sought to determine patterns of injury in our Latino trauma community targeting alcohol (EtOH) intoxication as an influential variable. With the information gained in our culturally specific and culturally sensitive trauma community, we can use the information to fine-tune our trauma preventive medicine programs. Trauma injuries are the third largest contributor to racial disparities in the United States. Alcohol is involved in approximately half of all trauma admissions to trauma centers around the country. Some investigators have shown that Latinos have higher rates of high-risk drinking, and this factor is independently associated with mortality after trauma. This study is a retrospective review of 524 Latino blunt and penetrating trauma admissions for years (2012-2014). Electronic medical records with the hospital trauma registry charts were evaluated. The trauma registry database included age, gender, EtOH, mechanism of injury, location, insurance, and disposition. Statistical significance was used with chi-square test. Our results show a predominantly male population with falls being the primary mechanism of injury. Intoxicated injuries occurred mostly at bars/clubs, but a substantial amount occurred at the workplace. Despite having a majority of the injuries occurring with patients that have Medicaid or Charity Care insurance, a certain amount of the alcohol-related injuries had private insurance. Many of our Latino trauma patients are still suffering from trauma-related EtOH intoxication. With the information obtained from our project, we will be able to fine-tune and target our trauma preventive medicine program to provide education for our inner-city Latino community of EtOH intoxication-related trauma injuries.

Effusive-constrictive tuberculous pericarditis in the setting of penetrating abdominal trauma.

Tuberculous pericarditis is rare in developed nations and is most commonly associated with effusive-constrictive pericarditis. We present the case of a 33-year-old man with a self-inflicted mid-abdominal stab wound. The patient underwent an exploratory laparotomy, revealing a grade IV pancreatic transection and injuries to the portal vein, right renal vein, inferior vena cava and the superior mesenteric vein. Repair of the vessels was performed and a pancreaticojejunostomy with a gastrojejunostomy was created for the pancreatic injury. The patient's hospital course was complicated by tuberculous effusive-constrictive pericarditis requiring emergent median sternotomy with opening of the pericardial sac and eventual expiration. The final cultures from the pericardial fluid demonstrated tuberculosis.

Utilizing quantitative measures of visceral adiposity in evaluating trauma patient outcomes.

INTRODUCTION: Body mass index (BMI) has commonly been used as a parameter to assess obesity in trauma patients. However, the variability of height and weight data in trauma patients limits the use of BMI as an accurate assessment tool in the trauma population. Quantitative radiologic measurements of visceral adiposity is an accurate method for assessing obesity in patients but requires further analysis before it can be accepted as a measurement tool for trauma patients. METHODS: A retrospective review of trauma cases with pre-operative CT scan from 2008 to 2015 produced 57 patients for evaluation. Preoperative BMI was calculated using measured height (m2) and weight (kg). Radiologic measurements of adiposity were obtained from preoperative CT scans using OsiriX DICOM viewer software. Visceral fat areas (VFA) and subcutaneous fat areas (SFA) were measured from a single axial slice at the level of L4-L5 intervertebral space. RESULTS: No statistically significant results were found relating visceral fat:subcutaneous fat ratios to length of stay or post-operative complications. Initial clinical observations noting an increased incidence of complications among patients with a V/S ≥ 0.4 demonstrates a possible link between obesity and poor outcomes in trauma patients. A statistically significant correlation was noted between length of stay, peri-nephric fat and injury severity score. DISCUSSION AND CONCLUSION: Our pilot study should be viewed as the foundation for a larger prospective study, utilizing quantitative measurements of visceral adiposity to assess outcomes in trauma patients.
