Psychiatric Diagnoses Are Associated With Postoperative Disparities in Patients Undergoing Major Colorectal Operations

BACKGROUND

Over 50% of hospitalized patients have comorbid psychiatric diagnoses, resulting in increased risk of morbidity such as longer lengths of stay, worse health-related quality of life, and increased mortality. However, data regarding colorectal surgery postoperative outcomes in patients with psychiatric diagnoses (PD) are limited.

METHODS

We queried a single institution's National Surgical Quality Improvement Program from 2013-2019 for major colorectal procedures. Postsurgical outcomes for patients with and without PD were compared. Primary outcomes were prolonged length of stay (pLOS) and 30-day readmission.

RESULTS

From a total of 1447 patients, 402 (27.8%) had PD. PD had more smokers (20.9% vs 15%) and higher mean body mass index (29.1 kg/m2 vs 28.2 kg/m2). Bivariate outcomes showed more surgical site infections (SSI) (10.2% vs 6.12%), reoperation (9.45% vs 6.35%), and pLOS (34.8% vs 29.0%) (all P values <.05) in the PD group. On multivariate analysis, PD had higher likelihood of reoperation (OR 1.53, 95% CI: [1.02-2.80]) and SSI (OR 1.82, 95% CI: [1.25-2.66]).

DISCUSSION

Psychiatric diagnoses are a risk factor for adverse outcomes after colorectal procedures. Further studies are needed to evaluate the benefit of perioperative mental health support services for these patients.

Use of a 5-Item Modified Frailty Index for Assessing Outcomes After Hartmann's Reversal: An ACS-NSQIP Study

BACKGROUND

Half of all patients with an end colostomy after sigmoid colectomy (Hartmann's procedure) never undergo Hartmann's reversal, frequently secondary to frailty. This retrospective cohort study evaluates the utility of a five-item modified frailty index (mFI-5) in predicting post-operative outcomes after Hartmann's reversal.

METHODS

The National Surgery Quality Improvement Program (NSQIP) database captured patients with elective Hartmann's reversals from 2011 to 2020. Clinical covariates were evaluated with univariate analysis and modified Poisson regression to determine association with overall morbidity, overall mortality, and extended length of stay (eLOS) when categorized by mFI-5 score.

RESULTS

15,172 patients underwent elective Hartmann's reversal (91.6% open and 8.4% laparoscopic). Patients were grouped by mFI-5 score (0: 48.7%, 1: 38.2%, ≥ 2: 13.1%). Adjusted multivariable analysis showed frail patients (mFI-5≥2) had increased overall mortality (OR 2.23, 95% CI 1.21-4.11), morbidity (OR 1.23, 95% CI 1.12-1.35), and eLOS (OR 1.12, 95% 1.02-1.23). Among frail patients, a laparoscopic approach was associated with decreased overall morbidity (OR .64, 95% CI 0.56-.73) and decreased eLOS (OR .46, 95% CI 0.39-.54) when compared to open approach.

DISCUSSION

An mFI-5 of ≥2 was associated with greater morbidity, mortality, and eLOS following Hartmann's reversal. However, there were no mortality or eLOS differences in patients with an mFI-5 of 1 and only a 14% increase in any morbidity, making these patients potentially good candidates for Hartmann's reversal. Furthermore, laparoscopic surgery was associated with a protective effect for overall morbidity and eLOS, potentially mitigating some of the risk associated with higher frailty scores.

The impact of month and season on the incidence of giant cell arteritis: an Intelligent Research in Sight (IRIS) Registry analysis

PURPOSE

Previous investigations into the relationship between season and the incidence of giant cell arteritis (GCA) have produced conflicting results. This study aimed to explore the impact of season and new diagnoses of GCA in a more definitive sense by employing the large dataset of the Intelligent Research in Sight (IRIS) database.

METHODS

The IRIS Registry was queried to identify new cases of GCA from 2013 to 2021. Statistical analyses were performed to determine the significance of the relationship between the time of year and the incidence of GCA on regional and nationwide bases via Cochran's Q statistical test.

RESULTS

A total of 27,339 eyes with a new diagnosis of GCA were identified. Neither the month nor the season of the year correlated with the incidence of GCA, regardless of geographic location within the USA (p > 0.05 for each variable).

CONCLUSIONS

In the USA, the incidence of GCA does not appear to vary by month or season. While this finding contradicts certain previous studies that identified a relationship, the cohort of patients identified from the IRIS Registry is much larger than that of previous investigations. Clinicians should be mindful of the possibility of GCA, regardless of the time of the year.

The Relationship Between Manifestation of Diabetes Insipidus and Estimated Glomerular Filtration Rate in Brain Death

OBJECTIVES

Systematic reviews have revealed that up to 50% of patients with brain death have residual hypothalamic/pituitary activity based on the absence of central diabetes insipidus (DI). We hypothesized that different degrees of renal dysfunction may impact the presence of DI in patients with brain death.

DESIGN

Single-center prospective data collection.

SETTING

ICUs in a tertiary academic hospital.

PATIENTS

All adult patients declared brain dead over 12 years.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

DI was diagnosed by polyuria, low urine specific gravity, and increasing serum sodium, measured in close proximity. Renal function was assessed by the estimated glomerular filtration rate (eGFR), calculated using the simplified modification of diet in renal disease equation. Analysis was completed in 192 of 234 patients with brain death after excluding those with missing data, those younger than 18 years and those on vasopressin infusions. One hundred twenty-two patients (63.5%) developed DI and 70 patients (36.5%) did not. The proportion of DI decreased significantly with decreasing eGFR: for eGFR greater than 60 mL/min, DI was present in 77.2%; for eGFR 15-60 mL/min, DI was present in 54.5%; for eGFR 14.9-9.8 mL/min, DI was present in 32%; none of the 14 patients with eGFR less than or equal to 9.7 mL/min ever experienced DI ( p < 0.001). Using logistic regression, for every 10 mL/min decrease in eGFR, the odds of DI decreased 0.83 times (95% CI, 0.76-0.90, p < 0.001).

CONCLUSIONS

Renal dysfunction significantly impacts DI's clinical manifestation in brain death. We report that patients who experience brain death with severe renal dysfunction may not develop clinical signs of DI.

Lunchbox trial: A randomized phase III trial of cisplatin and irradiation followed by carboplatin and paclitaxel versus sandwich therapy of carboplatin and paclitaxel followed by irradiation then carboplatin and paclitaxel for advanced endometrial carcinoma

BACKGROUND

The objective was to compare sequencing strategies for treatment of advanced endometrial carcinoma.

METHODS

Patients were eligible if they had FIGO 2009 Stage III or IVA endometrial carcinoma or Stage I or II serous or clear cell endometrial carcinoma and positive cytology. Patients were randomized to: Cisplatin 50 mg/m2 IV Days 1 and 29 plus radiation followed by Carboplatin AUC 5 or 6 plus Paclitaxel 175 mg/m2 q 21 days for 4 cycles (chemoRT then chemo) vs. Carboplatin AUC 6 plus Paclitaxel 175 mg/m2 q 21 days for 3 cycles followed by radiation followed by Carboplatin AUC 5 or 6 plus Paclitaxel 175 mg/m2 q 21 days for 3 cycles (sandwich therapy). Futility analysis was planned. The primary objective was to determine if chemoRT then chemo improves recurrence-free survival (RFS) compared to sandwich therapy.

RESULTS

Of the 48 patients enrolled at 8 sites, 42 patients were eligible for futility analysis, and the trial was closed early. The median follow-up was 30.9 months. The 3-year RFS was 85.7% (95% confidence interval [CI], 62 to 95) in the chemoRT then chemo arm and 73.4% (95% CI, 43 to 89) in the sandwich therapy group (p = 0.58). The 3-year overall survival (OS) was 88.4% (95% CI, 61 to 97) in the chemoRT then chemo arm and 80.9% (95% CI, 51 to 93) in the sandwich therapy group (p = 0.55).

CONCLUSION

There was no observed significant difference between chemoRT then chemo compared to sandwich therapy in terms of RFS, OS, or adverse events, although the trial was underpowered and closed early due to low accrual.

Children and Restraints Study in Emergency Ambulance Transport: An Observational Study and Analysis of Current Pediatric Ambulance Transport Practices

OBJECTIVES

The aims of this study were to identify the pediatric transport methods used by Emergency Medical Services (EMS) personnel in our area and to highlight the need for federal standards to unify prehospital transport of children.

METHODS

Children and Restraints Study in Emergency Ambulance Transport is a retrospective observational study of EMS arrivals to an academic pediatric emergency department for 1 year. Review of existing security footage from the ambulance entrance focused on the appropriateness of the selected restraints and the correctness of their application. A total of 3034 encounters were adequate for review and were matched to an emergency department encounter. Weight and age were identified from the chart. Patient weight was used in conjunction with video review to assess for the appropriateness of restraint selection.

RESULTS

A total of 53.5% (1622) of patients were transported using a weight appropriate device or restraint system. In 77.1% of all cases (2339), the devices or restraint systems were applied incorrectly. The best results were observed for commercial pediatric restraint devices (54.5% secured appropriately) and for convertible car seats (55.5%). Ambulance cot was used alone in 69.35% of all transports despite it being the appropriate choice in just 18.2% of transports.

CONCLUSIONS

Our findings confirmed that most pediatric patients transported by EMS are not appropriately secured and are at increased injury in a crash and potentially during normal vehicle operation. Opportunity exists for regulators, industry, and leaders in EMS and pediatrics to develop fiscally and operationally prudent techniques and devices to improve the safety of children in ambulances.

Association of open globe injury characteristics with outcome measures in the emergency department

PURPOSE

To evaluate the association of demographic and clinical features of emergency department (ED) patients presenting with open globe injuries (OG) with outcomes such as inpatient admission rate, length of stay (LOS), and total cost.

METHODS

The Nationwide Emergency Department Sample database 2018 and 2019 was used to analyze the association of demographic and clinical features of OG patients with outcome measures.

RESULTS

8404 OG patients were identified. Medicaid patients were associated with higher ED costs and a higher frequency of extended LOS. The 70+ age group was associated with higher inpatient admission. Frail patients were associated with significantly increased likelihood of inpatient admission, higher likelihood of extended LOS and higher total combined ED cost. Falls and being struck were associated with shorter LOS.

CONCLUSION

This study describes the most common demographic and clinical characteristics of OGIs that present to the ED, as well as the association of these characteristics with outcome measures such as inpatient admission rates, LOS, and total cost. The study further identified potential high-risk patients for prolonged length of stay. The findings will better optimize patient care protocols to improve outcomes.

Changing Faces: Factors Associated with the Intention to Pursue Plastic Surgery and Practice in Underserved Areas

Improving the number of plastic and reconstructive surgeons who provide care to patients in underserved communities is critical to achieving health equity. We aimed to identify factors associated with graduating medical students' intentions to pursue plastic surgery and practice in underserved areas.

Methods

De-identified data for US medical school graduates were obtained from the Association of American Medical Colleges for students who matriculated in academic years 2007-2008 and 2011-2012. Data collected included self-reported demographic and future practice intentions. Multivariate analysis was conducted to determine indicators of students' interest in plastic surgery, and their intention to practice in underserved areas.

Results

Of the 57,307 graduating US medical students in our cohort who completed the Graduation Questionnaire, 532 (0.9%) reported an intention to pursue plastic surgery. Hispanic [adjusted odds ratio (aOR): 1.45; 95% confidence interval (95% CI), 1.07-1.98] and multiracial (aOR: 1.59; 95% CI, 1.03-2.45) students were more likely to pursue plastic surgery compared with other surgical specialties. Among students interested in plastic surgery, compared with non-Hispanic White students, Black (aOR: 6.15; 95% CI, 1.96-19.26) students were more likely to report intention to practice in underserved areas. Students with community-engagement experiences were more likely to report intention to practice in underserved areas.

Conclusions

Diversity among medical trainees pursuing plastic and reconstructive surgery is critical for maintaining and expanding plastic surgery services rendered in underserved areas. These findings suggest that student demographics and experiences with community-engagement experiences are positive indicators of practicing in underserved communities.

A Contemporary Review of Surgical Approach and Outcomes in Pediatric Hypertrophic Pyloric Stenosis

INTRODUCTION

In order to define optimal resources and outcome standards for infant pyloromyotomy, we sought to perform a contemporary analysis of surgical approach (laparoscopic versus open) and outcomes.

METHODS

The National Surgical Quality Improvement Project Pediatrics Participant Use File (NSQIP PUF) was queried from 2016 to 2020. Utilization of laparoscopy was trended over time. Complication rates and length of stay were compared by operative approach.

RESULTS

9752 pyloromyotomies were included in the analysis. The utilization of laparoscopy steadily increased over the study time period (66% to 79%) and was associated with a shorter operative time. On multivariate regression, the utilization of laparoscopy was associated with a lower risk of overall complications, length of stay, and superficial surgical site infections. Overall complication rates were lower than previously reported (2.02%). The most common complication was superficial infection (1.2%).

CONCLUSIONS

In facilities reporting to pediatric National Quality Improvement Project, utilization of laparoscopy has steadily increased, and complication rates are lower than previously reported. Complication rates and length of stay were lower with the laparoscopic approach in this contemporary cohort. These results offer benchmarks for quality improvement initiatives. The laparoscopic approach should be standard in facilities performing this procedure.

From transabdominal to totally extra-peritoneal robotic ventral hernia repair: observations and outcomes

PURPOSE

While robotic-assisted hernia repair has increased the popularity of minimally invasive hernia surgery, selecting between the types of approaches is a challenge for both experts and novices alike. In this study, we compared a single surgeon's early experience transitioning from transabdominal hernia repair with sublay mesh in either the pre-peritoneal or retrorectus space (TA-SM) and enhanced-view totally extra-peritoneal (eTEP) ventral hernia repair in the peri-operative and long-term post-operative time periods.

METHODS

We conducted a retrospective review of 50 eTEP and 108 TA-SM procedures to collect demographics, intraoperative details, and 30-day and 1-year post-operative outcomes. Statistical analysis was performed utilizing Chi-square analysis, Fisher's test, and two sample t-tests with equal variances.

RESULTS

There were no significant differences in patient demographics or comorbidities. eTEP patients had larger defects (109.1 cm² vs. 31.8 cm², p = 0.043) and mesh used (432.8 cm² vs. 137.9 cm², p = 0.001). Operative times were equivalent (158.3 ± 90.6 min eTEP and 155.8 ± 65.2 min TA-SM, p = 0.84), but conversion to alternate procedure type was higher for the transabdominal approach (4% eTEP vs. 22% TA-SM, p < 0.05). Hospital stay was less in the eTEP cohort (1.3 days vs. 2.2 days, p < 0.05). Within 30 days, there were no significant differences in emergency visits or hospital readmissions. There was a greater propensity for eTEP patients to develop seromas (12.0% vs. 1.9%, p < 0.05). At 1 year, there was no statistically significant difference in recurrence rate (4.56% eTEP vs. 12.2% TA-SM, p = 0.28) respective to average time to recurrence (9.17 months eTEP vs. 11.05 months TA-SM).

CONCLUSION

The eTEP approach can be adopted safely and efficiently, and may have superior peri-operative outcomes including fewer conversions and reduced hospital stay.

Evaluation of Safety Measures at a Medical Summer Camp During the SARS-CoV-2 Pandemic

INTRODUCTION

SARS-CoV-2 poses challenges for the safe delivery of a camp experience with a medically complex camper population. Multiple studies have investigated the effect of nonpharmaceutical interventions for preventing SARS-CoV-2 transmission in traditional summer camp settings, but none in the medical summer camp settings. Our objective was to describe and evaluate the nonpharmaceutical interventions on SARS-CoV-2 transmission rate in a medical summer camp setting.

METHODS

This was a single-institution cross-sectional study conducted between June 2021 and August 2021 in a rural summer camp setting in upstate New York. Nonpharmaceutical interventions consisted of prearrival guidance on low-risk activities, obtaining negative SARS-CoV-2 polymerase chain reaction results within 72 h prior to arrival, adult SARS-CoV-2 vaccine mandate, universal masking mandate, small cohorts, daily symptom screening, and rapid testing on site. Primary cases were defined as an individual with a positive SARS-CoV-2 test result of any type while at camp or 2 wk after departure from camp without any known exposure at camp; secondary cases were defined as cases from potential exposures within camp.

RESULTS

Two hundred and ninety-three campers were included. Nine individuals were tested owing to potentially infectious symptoms while at camp. Thirty-four campers were tested because they arrived from a county with an a priori intermediate level of SARS-CoV-2 community spread. Zero on-site rapid tests were positive for SARS-CoV-2.

CONCLUSIONS

We describe the implementation of multilayered nonpharmaceutical interventions at a medical summer camp during the SARS-CoV-2 pandemic.

Should Teachers Carry Guns? An Emergency Room Survey of Parents of Two New York Communities

INTRODUCTION

The purpose of this study was to compare parents' perceptions of threats and solutions to school gun violence in two different communities.

METHODS

Parents of school-aged children visiting emergency rooms of two large trauma centers in Upstate New York (UNY) and New York City (NYC), between October 2019 and December 2020, were surveyed (UNY: n=202, NYC: n=100). Responses were compared by site, firearm experience, and concern for school safety.

RESULTS

Respondents from the two sites differed by sociodemographic characteristics. Of the 302 respondents, 64% feared a school shooting incident, but UNY respondents were less likely to report concern (46.5% vs 99%, p<0.001). UNY respondents were more likely to feel safe for their children (75.3% vs 7%, p<0.001) and to report feeling safer if guns were available to teachers (22.3% vs 6%, p <0.001). Both sites' respondents agreed on the need for armed police presence (76.7% vs 74%, p=0.11). Of the 193 parents concerned about a school shooting, 11.9% indicated feeling safer if guns were available to teachers versus 25.7% of those who were not (p=0.002). Agreement on solutions for making schools safer differed by the site. NYC respondents were unanimously supportive, but UNY support ranged from 52% for metal detectors to 84.5% for controlled entry points.

CONCLUSION

Although perceptions of child safety and experience with guns varied by location, most parents agreed on potential solutions, that it should be the security officers, not teachers, who should be carrying firearms and that armed police should be present in schools to provide safety.

First-generation and continuing-generation college graduates' application, acceptance, and matriculation to U.S. medical schools: a national cohort study

Many U.S. medical schools conduct holistic review of applicants to enhance the socioeconomic and experiential diversity of the physician workforce. The authors examined the role of first-generation college-graduate status on U.S. medical school application, acceptance, and matriculation, hypothesizing that first-generation (vs. continuing-generation) college graduates would be less likely to apply and gain acceptance to medical school.Secondary analysis of de-identified data from a retrospective national-cohort study was conducted for individuals who completed the 2001-2006 Association of American Medical Colleges (AAMC) Pre-Medical College Admission Test Questionnaire (PMQ) and the Medical College Admissions Test (MCAT). AAMC provided medical school application, acceptance, and matriculation data through 06/09/2013. Multivariable logistic regression models identified demographic, academic, and experiential variables independently associated with each outcome and differences between first-generation and continuing-generation students. Of 262,813 PMQ respondents, 211,216 (80.4%) MCAT examinees had complete data for analysis and 24.8% self-identified as first-generation college graduates. Of these, 142,847 (67.6%) applied to U.S. MD-degree-granting medical schools, of whom 86,486 (60.5%) were accepted, including 14,708 (17.0%) first-generation graduates; 84,844 (98.1%) acceptees matriculated. Adjusting for all variables, first-generation (vs. continuing-generation) college graduates were less likely to apply (odds ratio [aOR] 0.84; 95% confidence interval [CI], 0.82-0.86) and be accepted (aOR 0.86; 95% CI, 0.83-0.88) to medical school; accepted first-generation college graduates were as likely as their continuing-generation peers to matriculate. Students with (vs. without) paid work experience outside hospitals/labs/clinics were less likely to apply, be accepted, and matriculate into medical school. Increased efforts to mitigate structural socioeconomic vulnerabilities that may prevent first-generation college students from applying to medical school are needed. Expanded use of holistic review admissions practices may help decision makers value the strengths first-generation college graduates and other underrepresented applicants bring to medical educationand the physician workforce.

SARS-CoV-2 With Concurrent Respiratory Viral Infection as a Risk Factor for a Higher Level of Care in Hospitalized Pediatric Patients

OBJECTIVE

As of early 2021, there have been over 3.5 million pediatric cases of SARS-CoV-2, including 292 pediatric deaths in the United States. Although most pediatric patients present with mild disease, they are still at risk for developing significant morbidity requiring hospitalization and intensive care unit (ICU) level of care. This study was performed to evaluate if the presence of concurrent respiratory viral infections in pediatric patients admitted to the hospital with SARS-CoV-2 was associated with an increased rate of ICU level of care.

DESIGN

A multicenter, international, noninterventional, cross-sectional study using data provided through The Society of Critical Care Medicine Discovery Network Viral Infection and Respiratory Illness Universal Study database.

SETTING

The medical ward and ICU of 67 participating hospitals.

PATIENTS

Pediatric patients younger than 18 years hospitalized with SARS-CoV-2.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

A total of 922 patients were included. Among these patients, 391 required ICU level care and 31 had concurrent non-SARS-CoV-2 viral coinfection. In a multivariate analysis, after accounting for age, positive blood culture, positive sputum culture, preexisting chronic medical conditions, the presence of a viral respiratory coinfection was associated with need for ICU care (odds ratio, 3.6; 95% confidence interval, 1.6-9.4; P < 0.01).

CONCLUSIONS

This study demonstrates an association between concurrent SARS-CoV-2 infection with viral respiratory coinfection and the need for ICU care. Further research is needed to identify other risk factors that can be used to derive and validate a risk-stratification tool for disease severity in pediatric patients with SARS-CoV-2.

Detection of Ischemic Colitis on Routine Lower Endoscopy and Its Implications After Repair of Ruptured Abdominal Aortic Aneurysm

BACKGROUND

Ischemic colitis (IC) is a known significant complication after repair of a ruptured abdominal aortic aneurysm (rAAA). Lower endoscopy (colonoscopy or flexible sigmoidoscopy) is a helpful adjunct to aid decision making for surgical exploration. We believe routine use of lower endoscopy after rAAA repair provides better patient care through expeditious diagnosis and surgical care.

METHODS

We performed a retrospective chart review of rAAA repairs from 2008 to 2019. All patients undergo screening lower endoscopy after rAAA repair at our institution. The incidence of IC, mortality, and diagnostic characteristics of routine lower endoscopy was analyzed.

RESULTS

Of these, 182 patients underwent rAAA repair, among which 139 (76%) underwent routine lower endoscopy. Ischemic colitis of any grade was diagnosed in 25% of patients. The 30-day mortality was 11% compared to 19% in those without lower endoscopy. The presence of IC portended a 4-fold increase in mortality rate compared to those without (26% vs 6%, P = .005). Surgical exploration rate was 8% after routine lower endoscopy. Grade III ischemia on lower endoscopy had a sensitivity of 50% (95% CI 12-88) and specificity of 99% (95% CI 94-100) for transmural necrosis.

DISCUSSION

We found increased incidence of IC and reliable diagnostic characteristics of routine lower endoscopy in predicting the presence of transmural colonic ischemia. There was decreased mortality with use of routine lower endoscopy but this was not statistically significant.

Patients' Perspectives on Emergency Department COVID-19 Vaccination and Vaccination Messaging Through Randomized Vignettes

Objectives:

Emergency departments (EDs) could play an important role in the COVID-19 pandemic response by reaching patients who would otherwise not seek vaccination in the community. Prior to expanding COVID-19 vaccination to the acute care setting, we assessed ED patients’ COVID-19 vaccine status, perspectives, and hypothetical receptivity to ED-based vaccination.

Methods:

From January 11 through March 31, 2021, we conducted a multisite (Albany Medical Center, Boston Medical Center, Buffalo General Hospital, University of Cincinnati Medical Center, and Upstate Medical Center), cross-sectional survey of ED patients, with embedded randomization for participants to receive 1 of 4 vignette vaccination messages (simple opt-in message, recommendation by the hospital, community-oriented message, and acknowledgment of vaccine hesitancy). Main outcomes included COVID-19 vaccination status, prior intention to be vaccinated, and receptivity to randomized hypothetical vignette messages.

Results:

Of 610 participants, 122 (20.0%) were vaccinated, 234 (38.4%) had prior intent to be vaccinated, 111 (18.2%) were unsure as to prior intent, and 143 (23.4%) had no prior intent to be vaccinated. Vaccine hesitancy (participants who were vaccine unsure or did not intend to receive the vaccine) was associated with the following: age <45 years, female, non-Hispanic Black, no primary health care, and no prior influenza vaccination. Overall, 364 of 565 (64.4%; 95% CI, 60.3%-68.4%) were willing to accept a hypothetical vaccination in the ED. Among participants with prior vaccine hesitancy, a simple opt-in message resulted in the highest acceptance rates to hypothetical vaccination (39.7%; 95% CI, 27.6%-52.8%).

Conclusions:

EDs have appropriate patient populations to initiate COVID-19 vaccination programs as a supplement to community efforts. A simple opt-in approach may offer the best messaging to reach vaccine-hesitant ED patients.

Is Metformin Use Associated with Prolonged Overall Survival in Patients with Soft Tissue Sarcoma? A SEER-Medicare Study

BACKGROUND

Metformin, an oral drug used to treat patients with diabetes, has been associated with prolonged survival in patients with various visceral carcinomas. Although the exact mechanisms are unknown, preclinical translational studies demonstrate that metformin may impair tumor cellular metabolism, alter matrix turnover, and suppress oncogenic signaling pathways. Currently used chemotherapeutic agents have not been very successful in the adjuvant setting or for treating patients with metastatic sarcomas. We wanted to know whether metformin might be associated with improved survival in patients with a soft tissue sarcoma.

QUESTIONS/PURPOSES

In patients treated for a soft tissue sarcoma, we asked: (1) Is there an association between metformin use and longer survival? (2) How does this association differ, if at all, among patients with and without the diagnosis of diabetes?

METHODS

The Surveillance, Epidemiology, and End Results-Medicare (SEER-Medicare) database was used to identify patients with a diagnosis of soft tissue sarcoma from 2007 to 2016. Concomitant medication use was identified using National Drug Codes using the Medicare Part D event files. This database was chosen because of the large number of captured sarcoma patients, availability of tumor characteristics, and longitudinal linkage of Medicare data. A total of 14,650 patients were screened for inclusion. Patients with multiple malignancies, diagnosis at autopsy, or discrepant linkage to the Medicare database were excluded. Overall, 4606 patients were eligible for the study: 598 patients taking metformin and 4008 patients not taking metformin. A hazard of mortality (hazard ratio) was analyzed comparing patients taking metformin with those patient groups not taking metformin and expressed in terms of a 95% confidence interval. Cox regression analysis was used to control for patient-specific, disease-specific, and treatment-specific covariates.

RESULTS

Having adjusted for disease-, treatment-, and patient-specific characteristics, patients taking metformin experienced prolonged survival compared with all patients not taking metformin (HR 0.76 [95% CI 0.66 to 0.87]). Associated prolonged survival was also seen when patients taking metformin were compared with those patients not on metformin irrespective of a diabetes diagnosis (HR 0.79 [95% CI 0.66 to 0.94] compared with patients with a diagnosis of diabetes and HR 0.77 [95% CI 0.67 to 0.89] compared with patients who did not have a diagnosis of diabetes).

CONCLUSION

Without suggesting causation, we found that even after controlling for confounding variables such as Charlson comorbidity index, tumor grade, size, stage, and surgical/radiation treatment modalities, there was an association between metformin use and increased survival in patients with soft tissue sarcoma. When considered separately, this association persisted in patients not on metformin with and without a diabetes diagnosis. Although metformin is not normally prescribed to patients who do not have a diabetes diagnosis, these data support further study, and if these findings are substantiated, it might lead to the performance of multicenter, prospective clinical trials about the use of metformin as an adjuvant therapy for the treatment of soft tissue sarcoma in patients with and without a preexisting diabetes diagnosis.

LEVEL OF EVIDENCE

Level III, therapeutic study.

Influence of Society for Academic Emergency Medicine Foundation's Research Training Grant on postaward academic federal funding

OBJECTIVES

The objective was to measure the impact of the Society for Academic Emergency Medicine Foundation's (SAEMF) Research Training Grant (RTG) by comparing academic success in grant recipients versus non-recipient applicants. Our primary outcome was subsequent federal funding as a principal investigator (PI) or multiple principal investigator (MPI). Our secondary outcomes included subsequent K-award funding, R-series funding, R01 funding, and academic productivity measured by first author peer-reviewed publications.

METHODS

The authors examined all SAEMF RTG applicants from 2002 through 2019 (n = 109). Data were collected using the National Institutes of Health RePORTER database, a literature search using PubMed, and an online survey sent to all RTG applicants. Relative risks (RRs) with 95% confidence intervals (95% CI) were calculated.

RESULTS

Over 18 years, 18 of 109 (16.5%) RTG applicants were awarded by SAEMF. Subsequent federal funding as PI or MPI was obtained by 11 of the 18 RTG recipients compared to 29 of the 91 nonrecipients (61% vs. 33%, RR = 1.9; 95% CI = 1.2-3.1). The RTG award was also associated with increased probability of receiving a federal Career Development Award (K-series) (RR 2.0; 95% CI 1.1-3.9) and R-series award (RR 2.0; 95% CI 1.1-3.9) but not an R01 award (RR 2.1; 95% CI 0.8-5.3). The median number of first-authored peer reviewed manuscripts did not differ between RTG award recipients (14, IQR 8,44) and nonrecipients (14, IQR 6,30) (p = 0.5) though RTG recipients had a higher percentage of their publications as a first author (49% vs. 33%, p = 0.04).

CONCLUSIONS

SAEMF RTG awards were associated with increased probability of future federal funding, including career development awards and R-series awards but not R01 awards. RTG recipients also had a higher percentage of their peer reviewed publications as first author.

Computed Tomography Scan Utilization in Pediatric Trauma: Impact on Length of Stay and Incidence of False Positive Findings

INTRODUCTION

Computerized tomography (CT) scans are the mainstay of diagnostic imaging in blunt trauma. Particularly in pediatric trauma, utilization of CT scans has increased exponentially in recent years. Concerns regarding radiation exposure to this vulnerable population have resulted in increased scrutiny of practice. What is not known is if liberal imaging practices decrease length of stay by eliminating the need for clinical observation, and the impact of false-positive rates from liberal use of CT scanning on clinical outcomes.

METHODS

Medical records from a nonaccredited pediatric trauma center with a practice of liberal imaging were reviewed over a 2-year period. Total CT scans obtained were recorded, in addition to length of stay, age, and Injury Severity Score (ISS). Rates of clinically significant imaging findings were recorded, as were false positive findings and complications of imaging.

RESULTS

Out of 735 children, 58% underwent CT scanning, and if scanned, received an average of 2.4 studies. Clinically significant findings were documented in 20% of head CTs, 2% of cervical spine CTs, 3.5% of chest CTs, 24% of facial CTs, and 14.7% of abdominal CTs. False-positive findings were found in 1.5% of head CTs, 1.2% of cervical spine CTs, 2.4% of chest CTs, and 2.5% of abdominal CTs. Liberal CT scanning was not associated with decreased length of stay. In contrast, obtaining CT scans on more than 4 body regions was independently predictive of longer length of stay, independent of ISS.

CONCLUSIONS

False-positive rates of CT scans for trauma were low in this cohort. However, when scanning the cervical spine or the chest, for every 2 clinically significant findings obtained, there was at least one false positive result, calling into question the practice of liberal imaging of these regions. Liberal utilization of CT scan did not allow for more rapid discharge home, and for more than 4 CTs was independently associated with longer hospital stay.

Characteristics of medical students interested in emergency medicine with intention to practice in underserved areas

OBJECTIVES

Emergency departments serve a wide variety of racial, ethnic, socioeconomic, and gender backgrounds. It is currently unknown what characteristics of students who express interest in emergency medicine (EM) are associated with a simultaneous desire to work in medically underserved areas. We hypothesize that those who are underrepresented in medicine, are female, learn another language, and have more student debt will be more likely to practice in a medically underserved area.

METHODS

Data from the National Board of Medical Examiners, Association of American Medical Colleges (AAMC) Student Record System, and the AAMC Graduation Questionnaire were collected on a national cohort of 92,013 U.S. medical students who matriculated from 2007 through 2012. Extracted variables included planned practice area, intention to practice in underserved areas, race/ethnicity, sex, medical school experiences, age at matriculation, debt at graduation, and first-attempt USMLE Step 1 score.

RESULTS

EM-intending students who identified as female, non-Hispanic Black/African American, or Latinx/Hispanic; had a larger debt at graduation; had experiences with health education in the community; had global health experience; and had learned more than one language were more likely to report an intention to practice in underserved areas.

CONCLUSION

With the increasing importance of physician diversity to match those of the community being served, this study identifies factors associated with a desire of EM students to work in underserved areas. Medical schools and EM residencies may wish to consider these factors in their admissions process.

US Medical Licensing Exam Performance and American Board of Surgery Qualifying and Certifying Examinations

BACKGROUND

Program directors use United States Medical Licensing Exam (USMLE) scores as criteria for ranking applicants. First-time pass rates of the American Board of Surgery (ABS) Qualifying (QE) and Certifying (CE) Examinations have become important measures of residency program quality. USMLE Step 1 will become pass/fail in 2022.

STUDY DESIGN

American Board of Surgery QE and CE success rates were assessed considering multiple characteristics of highly ranked (top 20) applicants to 22 general surgery programs in 2011. Chi-square, t-test, Wilcoxon Rank sum, linear and logistic regression were used, as appropriate.

RESULTS

The QE and CE first attempt pass rates were 96% (235/244) and 86% (190/221), respectively. QE/CE success was not significantly associated with sex, race, research experience, or publications. Alpha Omega Alpha (AΩA) status was associated with success on the index CE (98% vs 83%; p = 0.008). Step 1 and Step 2 Clinical Knowledge (CK) scores of surgeons who passed QE on their first attempt were higher than scores of those who failed (Step 1: 233 vs 218; p = 0.016); (Step 2CK: 244 vs 228, p = 0.009). For every 10-point increase in Step 1 and 2CK scores, the odds of passing CE on the first attempt increased 1.5 times (95% CI 1.12, 2.0; p = 0.006) and 1.5 times (95% CI 1.11, 2.02, p = 0.008), respectively. For every 10-point increase in Steps 1 and 2CK scores, the odds of passing the QE on the first attempt increased 1.85 times (95% CI 1.11, 3.09; p = 0.018) and 1.86 times (95% CI 1.14, 3.06, p = 0.013), respectively.

CONCLUSIONS

USMLE Step 1 and Step 2 CK examination scores correlate with American Board of Surgery QE and CE performance and success. The USMLE decision to transition Step 1 to a pass/fail examination will require program directors to identify other factors that predict ABS performance for ranking applicants.

Change in Frequency of Invasive and Noninvasive Respiratory Support in Critically Ill Pediatric Subjects

BACKGROUND

Noninvasive respiratory support has become more popular in the pediatric population and may prevent or replace invasive procedures, such as endotracheal intubation, in certain circumstances. The objective was to examine the frequency of invasive and noninvasive respiratory support from 2009 to 2017 in critically ill pediatric patients and to determine patient-related factors associated with invasive support using the Virtual Pediatric Systems, LLC database.

METHODS

This was an analysis of prospectively collected data on admissions with respiratory support from 17 pediatric ICUs from 2009 to 2017 reported within the Virtual Pediatric Systems database. We determined the frequency of invasive and noninvasive respiratory support over the study period by measuring the number of admissions with either invasive or noninvasive support within a given year divided by the total number of pediatric ICU admissions with respiratory support during the same year. Factors associated with invasive support were examined in univariate and multivariate regressions.

RESULTS

A total of 69,262 cases of respiratory support were included. There was a decrease in the rate of invasive support over the study period from 66.9% to 48.5% (P value for test of trend < .001) and an increase in the rate of noninvasive support from 28.7% to 57.7% (P value for test of trend < .001). Trauma cases and subjects < 1 month old were more likely to receive invasive support. Cases occurring in later years and subjects with Black or Hispanic race were less likely to receive invasive support.

CONCLUSIONS

From 2009 to 2017, the frequency of admissions with invasive respiratory support decreased, and those with noninvasive respiratory support increased. By 2017, the frequency of noninvasive respiratory support was greater than that of invasive respiratory support.

Pediatric evidence-based imaging guidelines for adult trauma providers significantly reduces radiation exposure to children

Introduction

Evidence suggests that stand-alone pediatric trauma centers outperform adult and combined adult/pediatric trauma centers in limiting radiation exposure to injured children. We sought to determine the impact of implementing evidence-based guidelines for pediatric imaging at a combined adult (level 1) and pediatric (level 2) center. The initiative focused on trauma/critical care surgeons as the pediatric surgeons did not participate in the resuscitation and initial evaluation of injured children.

Methods

Imaging guidelines were developed from existing clinical studies. After 3 months of education, guidelines were implemented, and regular feedback was given to providers regarding compliance. Data were collected from the trauma registry for all pediatric patients (aged less than 15 years), in calendar years 2017 (pre-guideline) and 2019 (post-guideline). All admissions were analyzed, with subgroup analysis of children with multisystem trauma admitted to the trauma surgery service.

Results

Following guideline implementation, mean computed tomography (CT) scans per injured child fell by over 50% (.93 vs .45). For patients admitted to the trauma service, the mean fell by 58% (1.82 vs 0.76). The number of patients receiving more than 1 CT significantly decreased for all children (26% vs 10%), and particularly those admitted to the trauma service (52% vs 17%). During this time, there was only one injury missed at the initial admission, which was clinically insignificant (non-displaced skull fracture).

Conclusions

Implementation of evidence-based guidelines for imaging eliminates disparity in practices between a combined adult/pediatric trauma center and stand-alone pediatric trauma centers.

Biomarkers Predictive of Extubation and Survival of COVID-19 Patients

Purpose

Many patients with COVID-19 who develop acute respiratory distress syndrome (ARDS) require prolonged periods of mechanical ventilation. Mechanical ventilation may amplify ventilator-associated complications and extend resource utilization. A better understanding of prognostic indicators could help in the planning and distribution of resources, particularly in resource-limited areas. We analyzed laboratory studies of intubated COVID-19 patients with the goal of identifying biomarkers that may predict extubation success and survival to discharge.

Methods

A retrospective chart review was performed on all COVID-19 patients requiring mechanical ventilation between January 3, 2020, and January 7, 2020, in a single academic tertiary care center in Northeastern New York State. The electronic medical record was used to collect 14 laboratory variables at three time points: admission, intubation, and extubation (including terminal extubation) for all intubated intensive care unit (ICU) patients treated for COVID-19. Mean laboratory values were analyzed with the Mann-Whitney U test. Categorical variables were analyzed with the two-sample Wilcoxon rank-sum test.

Results

Seventy-two patients met the inclusion criteria. Forty-three patients were male. The mean age was 61 years. The overall mortality was 50%. On admission, intubated patients who survived had significantly higher platelet counts (p=0.024), and absolute lymphocyte counts (ALC; p=0.047). Notably, ferritin (p=0.018) and aspartate transaminase (AST; p=0.0045) levels were lower in survivors.

At the time of intubation, survivors again had a higher platelet count (p=0.024) and ALC (p=0.037) levels. They had a lower D-dimer (p=0.0014), ferritin (p=0.0015), lactate dehydrogenase (LDH; p=0.0145), and AST (p=0.018) compared to intubated patients who died.

At extubation, survivors had higher platelet count (p=0.0002), ALC (p=0.0013), and neutrophil/lymphocyte ratio (NLR; p=0.0024). Survivors had lower d-dimer (p=0.035), ferritin (p=0.0012), CRP (p=0.045), LDH (p=0.002), AST (p<0.001), and ALK (p=0.0048).

Conclusions

Biomarkers associated with increased risk of mortality include platelet count, ALC, lymphocyte percentage, NLR, D-dimer, ferritin, C-reactive protein (CRP), AST, alanine transaminase (ALT), and alkaline phosphatase (ALK). This study provides additional evidence that these biomarkers have prognostic value in patients with severe COVID-19. The goal is to find objective surrogate markers of disease improvement or success of extubation. When considered within the larger body of data, it is our hope that a mortality risk calculator can be generated for intubated COVID-19 patients.

High-Dose vs Standard-Dose Amoxicillin Plus Clavulanate for Adults With Acute Sinusitis: A Randomized Clinical Trial

IMPORTANCE

Acute bacterial sinusitis is common, but currently recommended antibiotic treatment provides minimal benefit.

OBJECTIVE

To confirm the previous finding that high-dose amoxicillin plus clavulanate (with double the amount of amoxicillin) may be superior to standard-dose amoxicillin plus clavulanate in adults.

DESIGN, SETTING, AND PARTICIPANTS

This double-blind, comparative-effectiveness randomized clinical trial was conducted from February 26, 2018, through May 10, 2020, at the academic primary care internal medicine and pediatrics practice of Albany Medical Center, located in Cohoes, New York. Participants included adults aged 18 years or older who were prescribed amoxicillin plus clavulanate for acute bacterial sinusitis diagnosed in accordance with the Infectious Diseases Society of America guidelines.

INTERVENTIONS

Amoxicillin 875 mg with clavulanate 125 mg plus either placebo (standard dose) or amoxicillin 875 mg (high dose) twice a day for 7 days.

MAIN OUTCOMES AND MEASURES

The primary efficacy outcome was a global rating of "a lot better" or "no symptoms" at the end of 3 days of treatment using a Global Rating of Improvement scale, with outcomes ranging from 1 (a lot worse) to 6 (no symptoms). The primary adverse effect outcome was severe diarrhea at 3 or 10 days after the start of treatment.

RESULTS

At an unplanned interim analysis prompted by COVID-19 restrictions, 157 of a projected 240 participants had been enrolled (mean age, 48.5 [range, 18.7-84.0] years; 117 women [74.5%]), with 79 randomized to the standard dose and 78 to the high dose; 9 and 12, respectively, withdrew or were lost to follow-up before the assessment of the primary outcome. At day 3, 31 of 70 participants (44.3%) in the standard-dose group reported a global rating of "a lot better" or "no symptoms," as did 24 of 66 (36.4%) in the high-dose group, for a difference of -7.9% (95% CI, -24.4% to 8.5%; P = .35). The study was, therefore, stopped for futility. Diarrhea was common in both groups by day 3, with any diarrhea reported in 29 of 71 participants (40.8%) receiving the standard dose and 28 of 65 (43.1%) receiving the high dose and severe diarrhea reported in 5 of 71 (7.0%) and 5 of 65 (7.7%), respectively.

CONCLUSIONS AND RELEVANCE

The results of this randomized clinical trial suggest that adults treated for clinically diagnosed acute sinusitis did not appear to benefit from taking high-dose compared with standard-dose amoxicillin plus clavulanate.

Impact of Enhanced Recovery after Surgery Protocols on Opioid Prescriptions at Discharge after Major Urological Cancer Surgery

INTRODUCTION

Enhanced recovery after surgery protocols are designed to limit the use of opioids during inpatient stay to facilitate recovery and early discharge. It is not clear whether the enhanced recovery after surgery related limitations on opioids are associated with opioid prescribing at discharge. We wished to evaluate whether the enhanced recovery after surgery efforts had an impact on opioid prescriptions given after discharge following major urological cancer surgery.

METHODS

We reviewed the opioid prescription data following hospital discharge after major urological cancer surgery from 2016 to 2018, including cystectomy, renal surgery (total, partial) and prostatectomy. Patient calls and refill requests were recorded for 30 days after discharge. Multivariable analysis was performed to evaluate the effect of various factors on normalized opioid tablets given at discharge.

RESULTS

A total of 409 patients met the inclusion criteria, with 207 before and 202 after ERAS protocols. Following enhanced recovery after surgery, potent opioid (oxycodone, hydrocodone) prescriptions decreased by 53% while tramadol use increased by more than four-fold (p <0.001). Reduction in opioid prescriptions was noted for prostatectomy (30%, p <0.001), cystectomy (27%, p=0.02) and all renal procedures (32%, p <0.001) after enhanced recovery after surgery protocol. On multivariable analysis, enhanced recovery after surgery protocol was an independent predictor of reduced opioids given at discharge.

CONCLUSIONS

Enhanced recovery after surgery protocol implementation was associated with a significant decrease in the opioid prescriptions at discharge after all major urological cancer procedures. Prescribing patterns shifted away from more potent opioids. These findings provide a benchmark for further interventions and reduction in the outpatient opioid prescriptions after open and minimally invasive surgery.

KEY WORDS

enhanced recovery after surgery; opioid epidemic; pain management; medication therapy management; analgesics, opioid.

Disparities in Acute Pain Treatment by Cognitive Status in Older Adults With Hip Fracture

BACKGROUND

We examined the disparities in emergency department (ED) pain treatment based on cognitive status in older adults with an acute hip fracture.

METHODS

Observational study in an academic ED in the Bronx, New York. One hundred forty-four adults aged 65 years and older with acute hip fracture were administered the Telephone Interview for Cognitive Status (TICS) while in the ED. The primary outcome was receipt of any parenteral analgesic. The risk factor of interest was cognitive impairment (TICS ≤ 25). Secondary outcomes included receipt of any opioid, receipt of any analgesic, total dose of analgesics in intravenous morphine equivalent units (MEQ), and time to receiving first analgesic.

RESULTS

Of the 87 (60%) study patients who were cognitively impaired, 60% received a parenteral analgesic compared to 79% of the 57 cognitively unimpaired patients (RR 0.76 [95% CI 0.61, 0.94]). The effect of cognitive impairment on receiving any opioids (RR: 0.81, 95% CI 0.67, 0.98) and any analgesic (RR: 0.85; 95% CI: 0.71, 1.01) was similar. The median analgesic dose in cognitively impaired patients was significantly lower than in cognitively unimpaired patients (4 MEQ vs 8 MEQ, p = .003).

CONCLUSION

Among older adults presenting to the ED with acute hip fracture, cognitive impairment was independently associated with lower likelihood of receiving analgesia and lower amount of opioid analgesia.

Pediatric cervical spine injury in the United States: Defining the burden of injury, need for operative intervention, and disparities in imaging across trauma centers

BACKGROUND

Pediatric cervical spine injury (PCSI) in children is rare. Incidence of PCSI requiring intervention is not known, and imaging practices for screening in United States trauma centers are not well described.

METHODS

The 2016 NTDB was queried for patients younger than 15 years with PCSI. Incidence of PCSI, operative interventions, and imaging rates were analyzed by age and ACS accreditation status.

RESULTS

Of 84,554 children, 873 (1.03%) had PCSI. Patients <4 years were less likely to have PCSI (0.68% vs. 1.1%, RR 0.59, p < 0.001). 165 children (0.20%) required an intervention for PCSI. 12.8% of all children were screened for PCSI with imaging, 9.3% with CT, and 3.2% with plain X-rays. In spite of similar injury and intervention rates, stand-alone pediatric trauma centers were less likely than others to image patients without PCSI (11% vs. 13% p < 0.001), less likely to utilize CT scan (5.8% vs. 10.6% p < 0.001) and more likely to utilize plain films (5.2% vs. 2.4% p < 0.001).

CONCLUSION

Despite exceedingly low rates of PSCI requiring intervention (0.2%), imaging rates for screening are significant. Stand-alone pediatric trauma centers outperform others in limiting unnecessary imaging.

Demographic Factors and Academic Outcomes Associated With Taking a Leave of Absence From Medical School

This cross-sectional study uses 2007-2012 data from the Association of American Medical Colleges’ Matriculating Student Questionnaire to evaluate student factors and academic outcomes associated with taking a leave of absence from medical school.

1059. Evaluating Hepatitis C Screening Rates and Successful Interventions at an Outpatient Medicine/Pediatrics Practice

Background

Despite the 2013 United States Preventive Services Task Force (USPSTF) recommendations, Hepatitis C (HCV) screening rates among patients born between 1945-1965 has remained below 25% (MacLean, 2018). At our outpatient academic suburban primary care practice in Albany County, NY, our hepatitis C baseline prior to interventions was 31.75%. In collaboration with Project FOCUS through Gilead, our practice attempted to increase screening rates among this birth cohort.

Methods

We performed a retrospective chart review on patients eligible for HCV screening with birth years 1945-1965 at the time of their visit at the Albany Med Internal Medicine/Pediatrics practice. We report monthly HCV screening from January 2018 to April 2020. In addition, we determined whether HCV screening rates differed by race, gender, ethnicity, private vs public insurance, and risk stratification or RAF (standard vs. high-risk patient).

Results

The chance that a test conducted for eligible patients increased from 29.9% (pre-intervention) to 58.76% in 2019 (post-intervention). From June 2019- December 2019, the testing rates were consistently above the 2019 average (Figure 1). There were no significant differences in HCV screening due to gender, race, ethnicity, or type of insurance (Table 1).

Figure 1. Hepatitis C Screening Rates at an Outpatient Medicine/Pediatrics Practice 2018-2020

Conclusion

In this outpatient Med/Peds practice, hepatitis C screening rates increased dramatically after incorporation of an EMR prompt, as well as nursing-generated orders for patients due for screening. There was no statistical difference in screening based on race, ethnicity, gender, or insurance type. Of note, high-risk patients were more likely to be screened, perhaps as they receive more case management services and are more likely to be in the office, increasing the opportunities for screening. The next step would be to adapt these interventions to screening all patients age 18-79, as per the updated 2020 USPSTF guidelines.

1058. Demographics of Hepatitis C Virus Antibody and RNA Positivity within an Emergency Department Screening Program

Background

In support of the recent United States Preventive Services Task Force’s (USPSTF) revised recommendations for non-targeted HCV screening, we have noted a shift away from active infections within the birth cohort (patients born between 1945-1965), as these individuals have often undergone successful treatment, and a shift towards younger adults who are RNA positive, especially people who use intravenous drugs (PWID).

Methods

Located in Northeastern New York State, Albany Medical Center conducts routine emergency department (ED) HCV screening, with active linkage to care. We performed a retrospective study of our HCV linkage to care data from April 2019 to June 2020. Patients were offered screening if they belonged to the birth cohort, were PWID, or at staff discretion. We estimated the effect of birth cohort, intravenous drug use and other potential risk factors on RNA positivity via Chi-square tests and Modified Poisson Regression.

Results

There were 242 people that were HCV antibody positive. The mean age was 50.9 years-old, with 118 (46.8%) in the birth cohort and 103 (42.56%) PWID. As compared to the birth cohort, a significantly greater proportion of non-birth cohort patients were PWID (62% vs 21.2%, p< 0.01) and homeless (17.7% vs 9.3%, p=0.05). Birth cohort patients were 0.55 times (95%CI: 0.39 to 0.79) less likely to be RNA positive. PWID were 2.22 times (95% CI: 1.58 to 3.13) and homeless people were 2.05 times (95% CI: 1.50 to 2.80) more likely to be RNA positive. After multivariable adjustment, birth cohort was not a significant risk factor for RNA positivity but PWID (RR: 1.84; 95% CI: 1.26 to 2.68) and homelessness (RR: 1.69; 95% CI: 1.20 to 2.39) were significantly associated with RNA positivity.

Conclusion

These data suggest that the RNA positivity rate is higher among the non-birth cohort age group but is explained by the higher prevalence of drug use and homeless. The findings support USPSTF’s new guidelines for testing all adults and shed light on the demographics of populations at risk for active infection vs. populations who are antibody positive and RNA negative. Further research might explore (a) whether these findings are applicable to other clinical settings and geographic locations and (b) the feasibility of targeting patients with active infection in settings such as the ED.

The Impact of an Enhanced Recovery Program on Loop Ileostomy Closure

BACKGROUND

The implementation of enhanced recovery after surgery (ERAS) protocols has decreased the length of stay (LOS) and complications in colorectal procedures. However, little data has been published on the subset of patients undergoing loop ileostomy closure. We investigated the outcomes of loop ileostomy reversals prior to and after initiation of an ERAS protocol.

METHODS

Patients undergoing ileostomy reversal over a 5-year period by 4 colorectal surgeons were studied and divided into pre-ERAS patients and ERAS patients in a retrospective, case-control study. Patient demographics, comorbidities, LOS, underlying disease process, index intra-abdominal procedure, readmission rate, and complications were evaluated.

RESULTS

Overall, 208 patients were analyzed 149 pre-ERAS and 59 ERAS-with median LOS significantly lower in the ERAS group than the pre-ERAS group (50.8 hours vs. 96.1 hours, P < .0001). In subgroup analysis, the LOS was significantly lower if the index procedure performed was laparoscopic when comparing ERAS to pre-ERAS (49.9 hours vs. 96.6 hours, P < .001). ERAS did not confer a significant decrease in the LOS during ileostomy reversal with open index procedures (72.9 hours vs. 95.5 hours, P = .05).

CONCLUSION

Utilizing an ERAS protocol is safe and effective for loop ileostomy closure with a shorter LOS and no difference in complication rates or 30-day readmission rates.

The Effect of an Enhanced Recovery Program on Elective Right Hemicolectomies for Crohn's Disease vs. Colon Cancer: A Retrospective Cohort Analysis

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols are widely employed in colorectal surgery, successful in reducing postoperative morbidities and hospital length of stay (LOS). However, ERAS effects on the inflammatory bowel disease population remain unclear. This study examines the postoperative course of both Crohn's disease (CD) and colon cancer (CC) patients after elective right hemicolectomies and compares the effectiveness of ERAS protocol.

METHODS

A retrospective analysis was performed on patients with CD and CC undergoing elective right hemicolectomies and ileocecectomies from January 2014 through June 2016 (pre-ERAS) and January 2017 through April 2019 (post-ERAS) from a single tertiary care center. Patient demographics and perioperative variables were examined, including prolonged postoperative ileus (PPOI), hospital LOS, and 30-day readmission.

RESULTS

98 CC patients and 91 CD patients met the inclusion criteria. The pre-ERAS CC and post-ERAS CC cohorts were significantly different: post-ERAS had fewer patients with congestive heart failure and chronic obstructive pulmonary disease and had higher albumin levels. The pre-ERAS CC cohort had significantly longer operative durations and higher rates of concomitant procedures than the post-ERAS CC cohort. Both patients with CC and CD had a reduction in LOS with implementation of ERAS, decreasing by 2.24 days (P = .002) and 1.21 days (P = .038), respectively. There was a reduction in rates of organ space infections with CD (pre .132, post .00, P = .007). There was a trend towards an increased rate of PPOI with CD (Pre .079, Post .226, P = .062).

DISCUSSION

The ERAS protocol significantly reduced LOS for both groups, without increasing 30-day readmission rates or other morbidities.

Management of Nonoperative Diverticulitis : Is Surgical Admission Always Best?

BACKGROUND

Institutional pathways (IPs) allow efficient utilization of health care resources. Recent literature reports decreased hospital length of stay (LOS), complications, and costs with the admittance of surgical disease to surgical services. Our study aimed to demonstrate that admission to surgery for nonoperative, acute diverticulitis reduces hospital LOS, and cost, with comparable complication rates.

METHODS

In January 2017, we defined IPs for diverticulitis, mandating emergency department admission to a surgical service. Patients admitted from October 2015 to June 2016 (pre-protocol, control cohort) were compared with those admitted January 2017-September 2018 (post-protocol, IP cohort). Primary outcomes included hospital LOS, direct cost, indirect cost, total cost, and 30-day readmission. Student's 2-tailed t-test and chi-square analysis were utilized, with statistical significance P < .05.

RESULTS

Nonoperative management of acute diverticulitis occurred in 62 (74%) patients in the control cohort. One hundred and eleven patients (85%) were admitted to the IP cohort. Patient characteristics were similar, except for a higher percentage of surgical patients utilizing private insurance and younger in age. Interestingly, no difference in hospital LOS (3.8 vs 4.7 days; P = 0.07), direct cost ($2639.44 vs $3251.52; P = .19), or overall cost ($5968.67 vs $6404.08, P = .61) was found between cohorts. Thirty-day readmission rates were comparable at 8% and 11% (P = .59).

CONCLUSION

Institutional policy mandating admissions for patients receiving nonoperative management of diverticulitis to surgical services does not reduce hospital LOS or cost. This argues that admission to medical services may be an acceptable practice. This raises the question, is acute diverticulitis always a surgical issue?

Perioperative Outcomes of Thoracoscopic Reoperations for Clinical Recurrence of Pulmonary Malignancy

The utility of thoracoscopic lung surgery is well established, however, reoperation for pulmonary resections has not been thoroughly studied. We sought to evaluate patient perioperative outcomes following redo thoracoscopic pulmonary resections for malignancy by comparing first and second ipsilateral operations. We included patients undergoing redo thoracoscopic pulmonary resections for clinically recurrent disease following prior lung resection for malignancy from January 1, 2011 to May 31, 2019. Nonmalignant indications were excluded. We analyzed type of procedure, diagnosis, rate of conversion to open, estimated blood loss, operating time, margin status, length of stay and complications. Forty-one patients met our inclusion criteria. The median age was 68 years (range 13-84) and 20 were women. Redo operations had longer lengths of stay with a trend toward higher rate of conversion to thoracotomy, but other perioperative outcomes were similar. No difference in outcomes was seen when patients were grouped by indication for reoperation (recurrence, multiple primaries, and metastasis) or approach of first operation (VATS vs open). However, patients undergoing an anatomic resection after a prior anatomic resection had more complications, higher blood loss, higher rate of conversions to thoracotomy, significantly longer length of stay and longer operative times than nonanatomic resections. Thoracoscopic reoperation for recurrent, metachronous, or metastatic cancer to the lung is a reasonable approach. However, the surgeon must recognize and counsel patients that in patients undergoing a redo anatomic resection, thoracoscopic reoperations are more difficult with more adverse outcomes.

Do Lidocaine Patches Reduce Opioid Use in Acute Rib Fractures?

BACKGROUND

Pain control is an important aspect of rib fracture management. With a rise in multimodal care approaches, we hypothesized that transdermal lidocaine patches reduce opioid utilization in hospitalized patients with acute rib fractures not requiring continuous opioid infusion.

METHODS

We performed a retrospective analysis of adult trauma patients with acute rib fractures admitted to the Trauma Service from January 2011 to October 2018. We compared patients who received transdermal lidocaine patches to those who did not and evaluated cumulative opioid consumption, expressed in morphine milligram equivalents (MMEs). Secondary outcomes included the rate of pulmonary complications and length of hospital stay.

RESULTS

Of the 21 190 trauma admissions, 3927 (18.5%) had rib fractures. Overall, 1555 patients who received continuous opioid infusion were excluded. Of the remaining 2372 patients, 725 (30.6%) patients received lidocaine patches. The mean total MME of patients who received lidocaine patches was 55.7 MME (30.7 MME on multivariate analysis) and was lower than that of patients who did not receive lidocaine patches (P ≤ .01). There was no difference in hospital length of stay (no lidocaine patches vs received lidocaine patches: 6.2 days vs 6.5 days, P = .34) or pulmonary complications (1.7% vs 2.8%, P = .08).

DISCUSSION

In admitted trauma patients with acute rib fractures not requiring continuous intravenous opiates, lidocaine patch use was associated with a significant decrease in opiate utilization during the patients' hospital course.

Physician Renewal of Chronically Prescribed Controlled Substances Based on Urine Drug Test Results

Objective: The effect of specific urine drug testing (UDT) results on physician prescribing habits has not been well described. The primary objective was to report renewal rates of chronically prescribed controlled substances based on types of inconsistent UDT results. Methods: We conducted a retrospective chart review over a 5-month period comparing prescription renewals rates for patients with consistent versus inconsistent UDTs. Inconsistent UDTs were defined by prescribed drug not detected or the presence of heroin, cocaine, nonprescribed opioids, nonprescribed benzodiazepines, or marijuana. Results: Of the 474 UDTs reviewed, 214 (45.1%) were inconsistent. The most common findings among inconsistent UDTs, including overlapping results, were prescribed drug not detected (26.8%) and the presence of marijuana (20.7%), nonprescribed opioids (9.9%), and nonprescribed benzodiazepines (6.1%). In contrast, cocaine (5.5%) and heroin (0.4%) were less likely to be found on UDTs for this population. The relative risk (RR) of prescription renewal was 0.64 (95% CI 0.57-0.71) for inconsistent UDTs versus consistent UDTs. Within the inconsistent UDTs, the renewal rates when marijuana (79.6%) or nonprescribed opioids or benzodiazepines (63.6%) were present were much higher than when heroin or cocaine were present (0.0%; P < .001). Patients whose prescribed controlled substance was not detected had a 55.8% renewal rate. Conclusions: Prescription renewal rates were high when patient UDTs contained nonprescribed marijuana, opioids, and benzodiazepines, or when the prescribed drug was not detected. Prescription renewal rates were low when illicit drugs, such as heroin and cocaine, were detected.

Racial disparities after stoma construction in colorectal surgery

AIM

Racial disparities are under-recognized among patients undergoing colorectal surgery. The purpose of this study was to determine the complication rates and surgical outcomes stratified by race and ethnicity among patients undergoing colorectal surgery with intestinal stoma creation.

METHOD

The ACS NSQIP database from 2013 to 2016 was used. Colon, rectum and small bowel cases requiring intestinal stoma creation were selected. Both African-American and other groups of minority patients were compared with Caucasian patients using a complex multivariable analysis model. Primary outcomes of interest were complication rates, mortality and extended hospital length of stay.

RESULTS

The study included 38 088 admissions. After multivariable analysis, African-American patients still had a prolonged length of hospital stay and higher complication rates. Other minorities also had a prolonged length of hospital stay and higher complication rates.

CONCLUSIONS

Both African-American and other groups of minority patients requiring an ostomy suffer significantly higher postoperative complication rates and a prolonged hospital length of stay, even after comorbidity adjustment. Access to care, socioeconomic status and comorbid disease management are all important factors for minority patients who undergo colorectal surgery requiring intestinal stoma construction.

Attainment of Guideline-Directed Medical Treatment in Stable Ischemic Heart Disease Patients With and Without Chronic Kidney Disease

BACKGROUND

Stable ischemic heart disease (SIHD) is prevalent in patients with chronic kidney disease (CKD); however, whether guideline-directed medical therapy (GDMT) is adequately implemented in patients with SIHD and CKD is unknown.

HYPOTHESIS

Use of GDMT and achievement of treatment targets would be higher in SIHD patients without CKD than in patients with CKD.

METHODS

This was a retrospective study of 563 consecutive patients with SIHD (mean age 67.8 years, 84% Caucasians, 40% females). CKD was defined as an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.73m² using the four-variable MDRD Study equation. We examined the likelihood of achieving GDMT targets (prescription of high-intensity statins, antiplatelet agents, renin-angiotensin-aldosterone system inhibitors (RAASi), and low-density lipoprotein cholesterol levels < 70 mg/dL, blood pressure < 140/90 mmHg, and hemoglobin A1C < 7% if diabetes) in patients with (n = 166) and without CKD (n = 397).

RESULTS

Compared with the non-CKD group, CKD patients were significantly older (72 vs 66 years; p < 0.001), more commonly female (49 vs 36%; p = 0.002), had a higher prevalence of diabetes (46 vs 34%; p = 0.004), and left ventricular systolic ejection fraction (LVEF) < 40% (23 vs. 10%, p < 0.001). All GDMT goals were achieved in 26% and 24% of patients with and without CKD, respectively (p = 0.712). There were no between-group differences in achieving individual GDMT goals with the exception of RAASi (CKD vs non-CKD: adjusted risk ratio 0.73, 95% CI 0.62-0.87; p < 0.001).

CONCLUSIONS

Attainment of GDMT goals in SIHD patients with CKD was similar to patients without CKD, with the exception of lower rates of RAASi use in the CKD group.

Are there variations in timing to tracheostomy in a tertiary academic medical center?

BACKGROUND

It is unclear what drives variation in timing to tracheostomy among different patients.

METHODS

Age, ethnicity, admission service, and income were retrospectively collected for patients undergoing tracheostomy in a Level 1 trauma center from 2007 to 2017. The primary outcome was time to tracheostomy with early tracheostomy (ET) or late tracheotomy (LT) defined as 3-7 or ≥ 10 days post-intubation, respectively. Secondary outcomes included length of stay (LOS), ventilator associated pneumonia, and mortality.

RESULTS

Among 1,640 patients, more men had ET compared to women (30% vs 28%; p = 0.05). The mean time to tracheostomy was 11.2 ± 7.7 days. Neurology and trauma patients had significantly shorter time to tracheostomy compared to other services. Age, ethnicity, and income showed no differences in timing to tracheostomy. Patients who underwent LT had a longer LOS (46 vs 32 days, p < 0.01) and higher mortality (19% vs 13% p < 0.01).

CONCLUSIONS

There were no disparities in timing to tracheostomy based on age, ethnicity, or income. We detected a hesitation in performing tracheostomies by certain providers with shorter LOS and improved mortality in ET.

A NSQIP analysis of trends in surgical outcomes for rectal cancer: What can we improve upon?

BACKGROUND

There is significant variation in rectal cancer outcomes in the USA, and reported outcomes have been inferior to those in other countries. In recognition of this fact, the American College of Surgeons (ACS) recently launched the Commission on Cancer (CoC) National Accreditation Program for Rectal Cancer (NAPRC) in an effort to further optimize rectal cancer care. Large surgical databases will play an important role in tracking surgical and oncologic outcomes. Our study sought to explore the trends in surgical outcomes over the decade prior to the NAPRC using a large national database.

METHODS

The ACS National Surgical Quality Improvement Program (NSQIP) database from 2005 to 2017 was used to select colorectal cancer cases which were divided into abdominal-colonic (AC) and pelvic-rectal (PR) cohorts based upon the operation performed. Outcomes of interest were occurrence of any major surgical complication, mortality within 30 days of procedure, and postoperative length of stay (LOS). Chi-square and two sample t-tests were used to evaluate association between various risk factors and outcomes. Modified Poisson regression was used to compare and estimate the unadjusted and adjusted effect of procedure type on the outcomes. STATA 15.1 was used for analysis and statistical significance was set at 0.05.

RESULTS

A total of 34,159 patients were analyzed. AC cases constituted 50.7% of the overall cohort. The two groups were relatively similar in demographic distribution, but the PR patients had higher rates of hypoalbuminemia and were sicker (ASA class 3 or greater). Rates of non-sphincter preserving operations ranged from 30 to 34%. Higher complication rates in the PR cohort were mainly infectious and surgical site complications, while rates of deep vein thrombosis and pulmonary embolism were similar between the two cohorts. On bivariate analysis, rates of mortality were similar between the two groups (AC: 1.02% vs PR: 0.91%, p = 0.395), while PR patients were found to be 1.36 times (95% CI: 1.32-1.41) more likely to have major complications and 1.40 times (95% CI: 1.35-1.44) more likely to have an extended LOS as compared to the AC patients. After multivariable analysis, PR patients continued to have a higher likelihood of major complications (IRR: 1.31, 95% CI 1.25-1.36) and extended LOS (IRR: 1.38, 95% CI: 1.33-1.43). 10-year trends showed a significant reduction in the percentage of patients with prolonged lengths of hospitalization as well as a reduction of nearly 20% in the mean LOS, but without improvement in morbidity or mortality.

CONCLUSIONS

Patients undergoing PR operations were more likely to have had major complications than were patients who underwent AC procedures; unfortunately no improvement in the rate of these complications or in mortality occurred. Perhaps the significant reduction in LOS is due in part to an increased prevalence of minimally invasive surgery and/or enhanced recovery protocols. Data were found to be lacking within NSQIP for several important variables including key oncologic data, stratification by surgical volume, and patient geographic location. We anticipate that the NAPRC should help improve PR surgical and oncologic outcomes including decreasing morbidity and mortality rates during the next decade.

Factors associated with Tdap vaccination receipt during pregnancy: a cross-sectional study

OBJECTIVE

Pertussis morbidity and mortality disproportionately affect infants younger than 1 year, who constitute 70% of deaths from pertussis. In 2017, 43% of infants younger than 6 months diagnosed with pertussis were hospitalized. In 2012, the Advisory Committee on Immunization Practices recommended that all pregnant women should receive Tdap (tetanus-diphtheria-acellular pertussis) vaccine between 27- and 36-weeks gestation in an effort to reduce infant pertussis morbidity and mortality. However, Tdap vaccination rates among pregnant women remain far from robust. The aim of this study was to assess factors associated with maternal Tdap uptake to help providers identify best practices that can improve Tdap receipt and identify women at risk for not receiving this important vaccine.

STUDY DESIGN

A retrospective cross-sectional study.

METHODS

A review of prenatal and delivery records was performed on all maternal-infant dyads with infants older than 36 weeks gestation admitted to the term nursery at Albany Medical Center from January 1, 2016 to April 16, 2016. A chi-squared analysis using STATA®, version 14.1, was performed to determine if any variables were associated with Tdap uptake, with statistical significance defined as P < 0.05. Multivariate analysis was performed to identify the variables which had the greatest effect on Tdap receipt.

RESULTS

Tdap vaccine was received by 65.8% of pregnant women (n = 400) in the study; median gestational age of receipt was 30 weeks. Maternal influenza vaccine receipt, infant hepatitis B vaccine receipt, provider recommendation of Tdap vaccination, and on-site availability of Tdap vaccine were all positively associated with maternal Tdap receipt during pregnancy.

CONCLUSION

Receipt of Tdap by pregnant women was highest in those who had received a provider recommendation about its benefits and who also received influenza vaccine during pregnancy. Because women who received the influenza vaccine themselves and also consented to have their infants receive the hepatitis B vaccine had significantly higher uptake rates, encouraging vaccines usage and combating vaccine hesitancy in general can improve Tdap uptake rates. A small, but statistically significant association with receipt of assisted reproductive technologies was also seen, meriting future research.
