A comparison of the psychometric properties of a person-administered vs. automated screening tool for posttraumatic stress disorder (PTSD) in traumatically injured patients

BACKGROUND

The American College of Surgeons Committee on Trauma (ACS-CoT) mandated that trauma centers have mental health screening and referral protocols in place by 2023. This study compares the Injured Trauma Survivor Screen (ITSS) and the Automated Electronic Medical Record (EMR) Screen to assess their performance in predicting risk for posttraumatic stress disorder (PTSD) within the same sample of trauma patients to inform trauma centers' decision when selecting a tool to best fit their current clinical practice.

METHODS

This was a secondary analysis of three prospective cohort studies of traumatically injured patients (N = 255). The ITSS and Automated EMR Screen were compared using receiver operating characteristic curves to predict risk of subsequent PTSD development. PTSD diagnosis at 6-month follow-up was assessed using the Clinician Administered PTSD Scale for DSM-5.

RESULTS

Just over half the sample screened positive on the ITSS (57.7%), while 67.8% screened positive on the Automated EMR Screen. The area under the curve (AUC) for the two screens was not significantly different (ITSS AUC = 0.745 versus Automated EMR Screen AUC = 0.694, p = 0.21), similar performance in PTSD risk predication within the same general trauma population. The ITSS and Automated EMR Screen had similar sensitivities (86.5%, 89.2%), and specificities (52.5%, 40.9%) respectively at their recommended cut-off points.

CONCLUSION

Both screens are psychometrically comparable. Therefore, trauma centers considering screening tools for PTSD risk to comply with the ACS-CoT 2023 mandate should consider their local resources and patient population. Regardless of screen selection, screening must be accompanied by a referral process to address the identified risk.

Physiologic parameters and radiologic findings can predict pulmonary complications and guide management in traumatic rib fractures

BACKGROUND

Traumatic rib fracture is associated with a high morbidity rate and identifying patients at risk of developing pulmonary complications (PC) can guide management and potentially decrease unnecessary intensive care admissions. Therefore, we sought to assess and compare the utility of a physiologic parameter, vital capacity (VC), with the admission radiologic findings (RibScore) in predicting PC in patients with rib fractures.

METHODS

This is a single-center retrospective review (2015-2018) of all adult (≥18 years) patients admitted to a Level I trauma center with traumatic rib fracture. Exclusion criteria included no CT scan and absence of VC within 48 h of admission. The cohort was stratified into two groups based on presence or absence of PC (pneumonia, unplanned intubation, unplanned transfer to the intensive care unit for a respiratory concern, or the need for a tracheostomy). Multivariable logistic regression models were constructed to identify predictors of PC.

RESULTS

A total of 654 patients met the inclusion criteria of whom 70 % were males. The median age was 51 years and fall (48 %) was the most common type of injury. A total of 36 patients (5.5 %) developed a pulmonary complication. These patients were more likely to be older, had a higher ISS, and were more likely to require a tube thoracostomy placement. On multivariable logistic regression, first VC ≤30 % (AOR: 4.29), day 1 VC ≤30 % (AOR: 3.61), day 2 VC ≤30 % (AOR: 5.54), Δ(Day2-Day1 VC) (AOR: 0.96), and RibScore ≥2 (AOR: 3.19) were significantly associated with PC. On discrimination analysis, day 2 VC had the highest area under the receiver operating characteristic curve (AuROC), 0.81, and was superior to first VC and day 1 VC in predicting PC. There was no statistically significant difference in predicting PC between day 2 VC and RibScore. On multivariable analysis, first VC ≤30 %, day 1 VC ≤30 %, day 2 VC ≤30 %, and admission RibScore ≥2 were associated with prolonged hospital and ICU LOS.

CONCLUSION

VC and RibScore emerged as independent predictors of PC. However, VC was not found to be superior to RibScore in predicting PC. Further prospective research is warranted to validate the findings of this study.

Thoracic Cavity Irrigation Prevents Retained Hemothorax and Decreases Surgical Intervention in Trauma Patients

INTRODUCTION

Retained hemothorax (HTX) is a common complication following thoracic trauma. Small studies demonstrate the benefit of thoracic cavity irrigation at the time of tube thoracostomy for the prevention of retained HTX. We sought to assess the effectiveness of chest irrigation in preventing retained HTX leading to a secondary surgical intervention.

METHODS

We performed a single-center retrospective study from 2017-2021 at a Level I trauma center comparing bedside thoracic cavity irrigation via tube thoracostomy (TT) versus no irrigation. Using the trauma registry, patients with traumatic HTX were identified. Exclusion criteria were TT placement at an outside hospital, no TT within 24 hours of admission, thoracotomy or video-assisted thoracoscopic surgery (VATS) prior to or within 6 hours after TT placement, VATS as part of rib fixation or diaphragmatic repair, and death within 96 hours of admission. Bivariate and multivariable analyses were conducted.

RESULTS

A total of 370 patients met the inclusion criteria, of whom 225 (61%) were irrigated. Patients who were irrigated were more likely to suffer a penetrating injury (41% vs 30%, p = 0.03) and less likely to have a flail chest (10% vs 21%, p = 0.01) (Table 1). On bivariate analysis, irrigation was associated with lower rates of VATS (6% vs 19%, p < 0.001) and retained HTX (10% vs 21%, p < 0.001) (Figure 1). The irrigated cohort had a shorter TT duration (4 vs 6 days, p < 0.001) and hospital length of stay (LOS) (7 vs 9 days, p = 0.04). On multivariable analysis, thoracic cavity irrigation had lower odds of VATS (aOR: 0.37, 95%CI: 0.30-0.54), retained HTX (aOR: 0.42, 95%CI: 0.25-0.74), and a shorter TT duration (β: -1.58, 95%CI: -2.52, -0.75).

CONCLUSION

Our 5-year experience with thoracic irrigation confirms findings from smaller studies that irrigation prevents retained HTX and decreases the need for surgical intervention.

A Pilot Project of a Post Discharge Care Team for Firearm Injury Survivors Decreases Emergency Department Utilization, Hospital Readmission Days, and Cost

BACKGROUND

Persons of low socioeconomic status are overrepresented in the firearm injury patient population and may experience challenges in accessing complex outpatient health systems. Consequently, outpatient care for these patients is plagued by poor follow-up and increased emergency department (ED) utilization. We developed a Post Discharge Care Team (PDCT) consisting of a dedicated trauma nurse navigator and medical social worker to bridge the gap between hospital discharge and outpatient care to improve recovery.

METHODS

Adult firearm injury survivors admitted to the trauma service were randomized 1:1 to receive either PDCT services or standard of care (SOC) workflows. The PDCT nurse provided education and set expectations regarding injuries, wound care, and outpatient follow up. The PDCT social worker performed a comprehensive assessment to identify concerns including housing and financial instability, food insecurity, or transportation issues. The primary outcome was ED utilization, with secondary outcomes including readmissions and overall healthcare costs compared between groups.

RESULTS

In the first six months of the study, a total of 44 patients were randomized to PDCT and 47 to SOC. There were 10 patients who visited the ED in the PDCT group compared to 16 in the SOC group (p = 0.23) for a total of 14 and 23 ED visits, respectively. There were 14 patients in the PDCT and 11 patients in the SOC groups who were readmitted (p = 0.31), but the PDCT group was readmitted for 27.9 fewer hospital days. After accounting for programmatic costs, the PDCT had a hospital savings of $34,542.71.

CONCLUSION

A collaborative, specialized Post Discharge Care Team for firearm injury survivors consisting of a dedicated trauma nurse navigator and medical social worker decreased outpatient ED utilization, readmission days, and was cost effective. Trauma centers with high volumes of penetrating trauma should consider a similar model to improve outpatient care for firearm injury survivors.

A Collaborative Multidisciplinary Trauma Program Improvement Team Improves VTE Chemoprophylaxis Guideline Compliance In Non-Operative Stable TBI

BACKGROUND

Delays in initiating venous thromboembolism (VTE) prophylaxis in patients suffering from traumatic brain injury (TBI) persist despite guidelines recommending early initiation. We hypothesized that the expansion of a Trauma Program Performance Improvement (PI) team will improve compliance of early (24-48 hour) initiation of VTE prophylaxis and will decrease VTE events in TBI patients.

METHODS

We performed a single-center retrospective review of all TBI patients admitted to a Level I trauma center before (2015-2016,) and after (2019-2020,) the expansion of the Trauma Performance Improvement and Patient Safety (PIPS) team and the creation of trauma process and outcome dashboards. Exclusion criteria included discharge or death within 48 hours of admission, expanding intracranial hemorrhage on CT scan, and a neurosurgical intervention (craniotomy, pressure monitor, or drains) prior to chemoprophylaxis initiation.

RESULTS

A total of 1,112 patients met the inclusion criteria, of which 54% (n = 604) were admitted after Trauma PIPS expansion. Following the addition of a dedicated PIPS nurse in the trauma program and creation of process dashboards, the time from stable CT to VTE prophylaxis initiation decreased (52 hours to 35 hours; p < 0.001) and more patients received chemoprophylaxis at 24-48 hours (59% from 36%, p < 0.001) after stable head CT. There was no significant difference in time from first head CT to stable CT (9 vs 9 hours; p = 0.15). The Contemporary group had a lower rate of VTE events (1% vs 4%; p < 0.001) with no increase in bleeding events (2% vs 2%; p = 0.97). On multivariable analysis, being in the Early cohort was an independent predictor of VTE events (aOR: 3.74; 95%CI: 1.45-6.16).

CONCLUSION

A collaborative multidisciplinary Trauma PIPS team improves guideline compliance. Initiation of VTE chemoprophylaxis within 24-48 hours of stable head CT is safe and effective.

Open versus endovascular repair of penetrating non-aortic arterial injuries: A systematic review and meta analysis

BACKGROUND

Non-aortic arterial injuries are common and are associated with high morbidity and mortality. Historically, open surgical repair (OSR) was the conventional method of repair. With recent advancements in minimally invasive techniques, endovascular repair (ER) has gained popularity. We sought to compare outcomes in patients undergoing endovascular and open repairs of traumatic non-aortic penetrating arterial injuries.

METHODS

A systematic review and meta-analysis was conducted using MEDLINE (OVID), Web of Science, Cochrane Library, and Scopus Database from January 1st, 1990, to March 20th, 2023. Titles and abstracts were screened, followed by full text review. Articles assessing clinically important outcomes between OSR and ER in penetrating arterial injuries were included. Exclusion criteria included blunt injuries, aortic injuries, pediatric populations, review articles, and non-English articles. Odds ratios (OR) and Cohen's d ratios were used to quantify differences in morbidity and mortality.

RESULTS

A total of 3770 articles were identified, of which 8 met inclusion criteria and were included in the review. The articles comprised a total of 8369 patients of whom 90 % were male with a median age of 28 years. 85 % of patients were treated with OSR while 15 % underwent ER. With regards to injury characteristics, those who underwent ER were less likely to present with concurrent venous injuries (OR: 0.41; 95 %CI: 0.18, 0.94; p = 0.03). Regarding hospital outcomes, patients who underwent ER had a lower likelihood of in-hospital or 30-day mortality (OR: 0.72; 95 %CI: 0.55, 0.95; p = 0.02) and compartment syndrome (OR: 0.29, 95 %CI: 0.12, 0.71; p = 0.007). The overall risk of bias was moderate.

CONCLUSION

Endovascular repair of non-aortic penetrating arterial injuries is increasingly common, however open repair remains the most common approach. Compared to ER, OSR was associated with higher odds of compartment syndrome and mortality. Further prospective research is warranted to determine the patient populations and injury patterns that most significantly benefit from an endovascular approach.

Improved follow-up care for gun violence survivors in the Trauma Quality of Life Clinic

Background

Outpatient follow-up represents a crucial opportunity to re-engage with gun violence survivors (GVS) and to facilitate positive health outcomes. Current outpatient models for firearm-related injuries and trauma care are inconsistent and unstandardized across trauma centers. This project describes the patient population served by the multidisciplinary Trauma Quality of Life (TQoL) Clinic for GVS. Also of primary interest was the outpatient follow-up services used by patients prior to their clinic appointment. Subsequent referrals placed during Clinic, as well as rate of attendance, was a secondary aim.

Methods

This was a descriptive retrospective analysis of a quality improvement project of the TQoL Clinic. Data were extracted from the electronic medical record and were supplemented with information from the trauma registry and the hospital-based violence intervention program database. Descriptive statistics characterized the patient population served. A Χ2 analysis was used to compare no-show rates for the TQoL Clinic against two historical cohorts of trauma clinic attendees.

Results

Most attendees were young (M=32.0, SD=1.8, range=15-88 years), Black (80.1%), and male (82.0%). Of the 306 total TQoL Clinic attendees, 82.3% attended their initial scheduled appointment. Most non-attendee patients rescheduled their appointments (92.1%), and 89.5% attended the rescheduled appointment. TQoL Clinic demonstrated a significantly lower no-show rate than the traditional trauma clinic model, including after the implementation of the hospital's inpatient violence intervention program (χ2(2)=75.52, p<0.001).

Conclusion

The TQoL Clinic has demonstrated improved outpatient follow-up to address the comprehensive needs of GVS. Trauma centers with high gunshot wound volume should consider the implementation of the multidisciplinary TQoL Clinic model to increase access to care and to continue partnership with violence intervention programs to address health outcomes in those most at risk of future morbidity and mortality.

A Prescribing Guideline Decreases Postoperative Opioid Prescribing in Emergency General Surgery

INTRODUCTION

Patients prescribed higher opioid dosages have a higher risk of persistent opioid use, overdose, and death. There is a lack of standardization for opioid prescribing for acute surgical pain in emergency general surgery (EGS) patients. We hypothesized that implementing a guideline to standardize opioid prescribing would be associated with a decrease in prescribing at hospital discharge for EGS patients without increasing additional postdischarge refills.

METHODS

This was a quasi-experimental study evaluating opioid prescribing by EGS providers before and after the implementation of a prescribing guideline. Patients were assigned to preguideline and postguideline groups based on admission date surrounding the implementation of the guideline. The primary outcome was the proportion of patients receiving an opioid prescription for ≥50 Morphine Milligram Equivalents (MME) per day on hospital discharge.

RESULTS

There were 227 patients in the preguideline group and 226 patients in the postguideline group. After guideline implementation, median total MME prescribed decreased from 113 (interquartile range = 75) to 75 (interquartile range = 75, P = 0.03). The proportion of patients receiving a prescription for daily MME ≥50 also decreased from 75% to 25% (P ≤0.01). There were no increases in requested refills (17% versus 16%, P = 0.72) or received refills (14% versus 14%, P = 0.98). Guideline compliance ranged from 75% in ventral hernia repair patients to 94% in laparoscopic cholecystectomy patients.

CONCLUSIONS

A departmental guideline to standardize postoperative opioid prescriptions was associated with a decrease in the amount of MMEs prescribed to EGS patients without an increase in requested or received refills.

Early career acute care surgeons' priorities and perspectives: A mixed-methods analysis to better understand full-time employment

BACKGROUND

Understanding the expectations of early career acute care surgeons will help clarify the practice and employment models that will attract and retain high-quality surgeons, thereby sustaining our workforce. This study aimed to outline the clinical and academic preferences and priorities of early career acute care surgeons and to better define full-time employment.

METHODS

A survey on clinical responsibilities, employment preferences, work priorities, and compensation was distributed to early career acute care surgeons in the first 5 years of practice. A subset of agreeable respondents underwent virtual semistructured interviews. Both quantitative and thematic analysis were used to describe current responsibilities, expectations, and perspectives.

RESULTS

Of 471 surgeons, 167 responded (35%), the majority of whom were assistant professors within the first 3 years of practice (80%). The median desired clinical volume was 24 clinical weeks and 48 call shifts per year, 4 weeks less than their median current clinical volume. Most respondents (61%) preferred a service-based model. The top priorities cited in choosing a job were geography, work schedule, and compensation. Qualitative interviews identified themes related to defining full-time employment, first job expectations and realities, and the often-misaligned system and surgeon.

CONCLUSION

Understanding the perspectives of early career surgeons entering the workforce is important particularly in the field of acute care surgery where no standard workload or practice model exists. The wide variety of expectations, practice models, and schedule preferences may lead to a mismatch between surgeon desires and employment expectation. Consistent employment standards across our specialty would provide a framework for sustainability.

The efficacy of various Enoxaparin dosing regimens in general surgery patients: A systematic review

BACKGROUND

Patients undergoing surgical procedures are at an increased risk of venous thromboembolism events. A fixed Enoxaparin dosing regimen is the standard of care for chemoprophylaxis in most institutions; however, breakthrough venous thromboembolism events are still reported. We aimed to systematically review the literature to determine the ability of various Enoxaparin dosing regimens to achieve adequate prophylactic anti-Xa levels for venous thromboembolism prevention in hospitalized general surgery patients. Additionally, we aimed to assess the correlation between subprophylactic anti-Xa levels and the development of clinically significant venous thromboembolism events.

METHODS

A systematic review was conducted using major databases from January 1, 1993, to February 17, 2023. Two independent researchers screened titles and abstracts, followed by a full-text review. Articles were included if Enoxaparin dosing regimens were evaluated by anti-Xa levels. Exclusion criteria included systematic reviews, pediatric population, nongeneral surgery (defined as trauma, orthopedics, plastics, and neurosurgery), and non-Enoxaparin chemoprophylaxis. The primary outcome was peak Anti-Xa level measured at steady state concentration. The risk of bias was assessed using the Risk of Bias in Nonrandomized studies-of Intervention tool.

RESULTS

A total of 6,760 articles were extracted, of which 19 were included in the scoping review. Nine studies included bariatric patients, whereas 5 studies explored abdominal surgical oncology patients. Three studies assessed thoracic surgery patients, and 2 studies included patients undergoing "general surgery" procedures. A total of 1,502 patients were included. The mean age was 47 years, and 38% were males. The percentages of patients reaching adequate prophylactic anti-Xa levels were 39%, 61%, 15%, 50%, and 78% across the 40 mg daily, 40 mg twice daily, 30 mg twice daily, and weight-tiered, and body mass index-based groups, respectively. The overall risk of bias was low to moderate.

CONCLUSION

Fixed Enoxaparin dosing regimens are not correlated with adequate anti-Xa levels in general surgery patients. Additional research is warranted to assess the efficacy of dosing regimens based on novel physiologic parameters (such as estimated blood volume).

Anti-Factor Xa Monitoring of Enoxaparin Thromboembolism Prophylaxis in Emergency General Surgery Patients

BACKGROUND

Rates of venous thromboembolism (VTE) remain high in emergency general surgery (EGS) patients despite chemical VTE prophylaxis. Emerging literature supports anti-factor Xa (AFXa) monitoring for patients on enoxaparin (LMWH), though a significant knowledge gap remains regarding the optimal dosing and monitoring in EGS patients. We hypothesize that standard dose VTE prophylaxis regimens provide inadequate VTE prophylaxis in EGS patients.

STUDY DESIGN

A prospective cohort study of all adult EGS patients at a single institution between August 2021-February 2022 receiving standard dose LMWH for VTE prophylaxis was performed. AFXa levels were obtained 4-hours following the third dose of enoxaparin with a target range of 0.3-0.5 IU/mL. Adjustment to dosing and repeat AFXa measurement after the adjusted 3 rd dose was obtained.

RESULTS

A total of 81 patients underwent AFXa monitoring, the majority (75%) of whom were started on 40 mg LMWH daily. Initial peak AFXa measurement was low in 87.7% of patients (mean 0.16 IU/mL). Of patients who had an initial low AFXa, remained admitted, and underwent dosing adjustment and AFXa reassessment (27%), the majority were adjusted to either 30mg or 40mg LMWH twice daily (23.7% and 55%, respectively), with 82% of patients remaining low. There were no significant differences in demographics or body mass index between those with low vs. adequate AFXa levels at either initial or subsequent measurement.

CONCLUSION

Standard LMWH dosing provides inadequate AFXa inhibition for adequate VTE prophylaxis. These findings highlight the importance of ongoing AFXa monitoring and the need to establish clinical protocols to improve VTE prophylaxis in EGS patients.

Isolated Enterococcus faecalis pulmonary valve endocarditis without precipitating risk factors: A case report describing delayed need for surgery three years after antimicrobial therapy

INTRODUCTION AND IMPORTANCE

Isolated Enterococcus faecalis pulmonary valve endocarditis (PVE) without precipitating risk factors is exceeding rare, as fewer than ten cases have been published in the literature, most of which did not require surgical intervention.

CASE PRESENTATION

An elderly individual presented for evaluation of dyspnea, fatigue, dizziness, weight loss, and a low-grade fever. The patient denied intravenous drug abuse, blood-borne viral infection, cardiac trauma, congenital heart disease, and immunocompromise. Echocardiography identified a large vegetation on the right pulmonary valve leaflet consistent with isolated PVE. Blood cultures grew E. faecalis. Computed tomography failed to reveal an infectious source. The patient completed a six-week course of antibiotics and was followed with serial echocardiography for three years, but subsequently developed severe pulmonic insufficiency and right heart failure necessitating pulmonary valve replacement.

CLINICAL DISCUSSION

Isolated PVE is responsible for less than 2.0% of all cases of infective endocarditis. The vast majority of reported cases are associated with risk factors and are caused by gram-positive organisms including Staphylococcus species and Streptococcus viridans. Echocardiography identifies most cases of isolated PVE. Septic embolization of vegetation fragments to lung parenchyma is common. Surgery is reserved for patients who are unresponsive to antibiotics or those who develop severe pulmonary insufficiency with symptoms of right heart failure, as seen here.

CONCLUSION

We present an unusual case of isolated E. faecalis PVE without known risk factors that required pulmonary valve replacement three years after antimicrobial therapy.

A simple algorithm to improve quality while reducing resource utilization in evaluation of suspected appendicitis in children

BACKGROUND

With similar effectiveness of ultrasonography, our institution replaced CT imaging with ultrasound for diagnosing appendicitis in children. An unexpected consequence was the overutilization of ultrasound. Our objective was to establish measures that could help prevent this overuse.

METHODS

A retrospective chart review of 327 consecutive pediatric patients evaluated for appendicitis between October 2014 and September 2015 at our institution was performed. Data on clinical, radiographic, and histopathologic findings were reviewed. Diagnostic accuracy of US and white blood cell (WBC) values was determined. An algorithm was created.

RESULTS

327 (100%) patients received an ultrasound for suspected appendicitis. WBC of 10,000/μl was determined to be the primary discriminant for management and ultrasound utilization. If a WBC ≥10,000/μL had been utilized as criteria for imaging, 49.5% fewer patients would have received an ultrasound.

CONCLUSIONS

Clinical exam, WBC count, and surgery consultation prior to ultrasonography can lessen then need for ultrasound utilization in children with suspected appendicitis.
