Retention of Knowledge After Opioid Education in Surgical Interns

BACKGROUND

In many academic centers, opioid prescribing is managed primarily by residents with little or no formal opioid education. The present study evaluates intern knowledge and comfort with appropriate opioid prescribing 7 months after an organized opioid education effort.

MATERIALS AND METHODS

A repeat knowledge and attitude survey was sent to surgical interns who had completed an initial opioid education training session 7 months before the study. Results were compared to post-education assessment results in the same cohort.

SETTING

16 general surgery and podiatric surgery interns at a single academic medical center.

RESULTS

The mean percentage of correct answers on follow-up was 67.6% identical to the average post-session score of 67.6%. Interns reported comfort with opioid prescribing increased to a mean score of 5.9 (out of 10) on follow-up compared to post-session score of 5.19.

CONCLUSIONS

Surgical interns have significant gaps in knowledge for optimal prescribing and management of opioid prescriptions. Targeted education demonstrates significant and lasting improvement in opioid assessment scores, but there remains room for improvement.

Emergency department thoracotomy in children: A Pediatric Trauma Society, Western Trauma Association, and Eastern Association for the Surgery of Trauma systematic review and practice management guideline

BACKGROUND

The role of emergency department resuscitative thoracotomy (EDT) in traumatically injured children has not been elucidated. We aimed to perform a systematic review and create evidence-based guidelines to answer the following PICO (population, intervention, comparator, and outcome) question: should pediatric patients who present to the emergency department pulseless (with or without signs of life [SOL]) after traumatic injuries (penetrating thoracic, penetrating abdominopelvic, or blunt) undergo EDT (vs. no EDT) to improve survival and neurologically intact survival?

METHODS

Using Grading of Recommendations Assessment, Development and Evaluation methodology, a group of 12 pediatric trauma experts from the Pediatric Trauma Society, Western Trauma Association, and Eastern Association for the Surgery of Trauma assembled to perform a systematic review. A consensus conference was conducted, a database was queried, abstracts and manuscripts were reviewed, data extraction was performed, and evidence quality was determined. Evidence tables were generated, and the committee voted on guideline recommendations.

RESULTS

Three hundred three articles were identified. Eleven studies met the inclusion criteria and were used for guideline creation, providing 319 pediatric patients who underwent EDT. No data were available on patients who did not undergo EDT. For each PICO, the quality of evidence was very low based on the serious risk of bias and serious or very serious imprecision.

CONCLUSION

Based on low-quality data, we make the following recommendations. We conditionally recommend EDT when a child presents pulseless with SOL to the emergency department following penetrating thoracic injury, penetrating abdominopelvic injury and after blunt injury if emergency adjuncts point to a thoracic source. We conditionally recommend against EDT when a pediatric patient presents pulseless without SOL after penetrating thoracic and penetrating abdominopelvic injury. We strongly recommend against EDT in the patient without SOL after blunt injury.

Nonfatal Injuries Sustained in Mass Shootings in the US, 2012-2019: Injury Diagnosis Matrix, Incident Context, and Public Health Considerations

INTRODUCTION

The epidemic of gun violence in the United States (US) is exacerbated by frequent mass shootings. In 2021, there were 698 mass shootings in the US, resulting in 705 deaths and 2,830 injuries. This is a companion paper to a publication in JAMA Network Open, in which the nonfatal outcomes of victims of mass shootings have been only partially described.

METHODS

We gathered clinical and logistic information from 31 hospitals in the US about 403 survivors of 13 mass shootings, each event involving greater than 10 injuries, from 2012-19. Local champions in emergency medicine and trauma surgery provided clinical data from electronic health records within 24 hours of a mass shooting. We organized descriptive statistics of individual-level diagnoses recorded in medical records using International Classification of Diseases codes, according to the Barell Injury Diagnosis Matrix (BIDM), a standardized tool that classifies 12 types of injuries within 36 body regions.

RESULTS

Of the 403 patients who were evaluated at a hospital, 364 sustained physical injuries-252 by gunshot wound (GSW) and 112 by non-ballistic trauma-and 39 were uninjured. Fifty patients had 75 psychiatric diagnoses. Nearly 10% of victims came to the hospital for symptoms triggered by, but not directly related to, the shooting, or for exacerbations of underlying conditions. There were 362 gunshot wounds recorded in the Barell Matrix (1.44 per patient). The Emergency Severity Index (ESI) distribution was skewed toward higher acuity than typical for an emergency department (ED), with 15.1% ESI 1 and 17.6% ESI 2 patients. Semi-automatic firearms were used in 100% of these civilian public mass shootings, with 50 total weapons for 13 shootings (Route 91 Harvest Festival, Las Vegas. 24). Assailant motivations were reported to be associated with hate crimes in 23.1%.

CONCLUSION

Survivors of mass shootings have substantial morbidity and characteristic injury distribution, but 37% of victims had no GSW. Law enforcement, emergency medical systems, and hospital and ED disaster planners can use this information for injury mitigation and public policy planning. The BIDM is useful to organize data regarding gun violence injuries. We call for additional research funding to prevent and mitigate interpersonal firearm injuries, and for the National Violent Death Reporting System to expand tracking of injuries, their sequelae, complications, and societal costs.

Association of Postsurgical Opioid Refills for Patients With Risk of Opioid Misuse and Chronic Opioid Use Among Family Members

IMPORTANCE

The US health care system is experiencing a sharp increase in opioid-related adverse events and spending, and opioid overprescription may be a key factor in this crisis. Ambient opioid exposure within households is one of the known major dangers of overprescription.

OBJECTIVE

To quantify the association between the postsurgical initiation of prescription opioid use in opioid-naive patients and the subsequent prescription opioid misuse and chronic opioid use among opioid-naive family members.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was conducted using administrative data from the database of a US commercial insurance provider with more than 35 million covered individuals. Participants included pairs of patients who underwent surgery from January 1, 2008, to December 31, 2016, and their family members within the same household. Data were analyzed from January 1 to November 30, 2018.

EXPOSURES

Duration of opioid exposure and refills of opioid prescriptions received by patients after surgery.

MAIN OUTCOMES AND MEASURES

Risk of opioid misuse and chronic opioid use in family members were calculated using inverse probability weighted Cox proportional hazards regression models.

RESULTS

The final cohort included 843 531 pairs of patients and family members. Most pairs included female patients (445 456 [52.8%]) and male family members (442 992 [52.5%]), and a plurality of pairs included patients in the 45 to 54 years age group (249 369 [29.6%]) and family members in the 15 to 24 years age group (313 707 [37.2%]). A total of 3894 opioid misuse events (0.5%) and 7485 chronic opioid use events (0.9%) occurred in family members. In adjusted models, each additional opioid prescription refill for the patient was associated with a 19.2% (95% CI, 14.5%-24.0%) increase in hazard of opioid misuse in family members. The risk of opioid misuse appeared to increase only in households in which the patient obtained refills. Family members in households with any refill had a 32.9% (95% CI, 22.7%-43.8%) increased adjusted hazard of opioid misuse. When patients became chronic opioid users, the hazard ratio for opioid misuse among family members was 2.52 (95% CI, 1.68-3.80), and similar patterns were found for chronic opioid use.

CONCLUSIONS AND RELEVANCE

This cohort study found that opioid exposure was a household risk. Family members of a patient who received opioid prescription refills after surgery had an increased risk of opioid misuse and chronic opioid use.

Injury Characteristics, Outcomes, and Health Care Services Use Associated With Nonfatal Injuries Sustained in Mass Shootings in the US, 2012-2019

IMPORTANCE

Civilian public mass shootings (CPMSs) in the US result in substantial injuries. However, the types and consequences of these injuries have not been systematically described.

OBJECTIVE

To describe the injury characteristics, outcomes, and health care burden associated with nonfatal injuries sustained during CPMSs and to better understand the consequences to patients, hospitals, and society at large.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective case series of nonfatal injuries from 13 consecutive CPMSs (defined as ≥10 injured individuals) from 31 hospitals in the US from July 20, 2012, to August 31, 2019, used data from trauma logs and medical records to capture injuries, procedures, lengths of stay, functional impairment, disposition, and charges. A total of 403 individuals treated in hospitals within 24 hours of the CPMSs were included in the analysis. Data were analyzed from October 27 to December 5, 2021.

EXPOSURES

Nonfatal injuries sustained during CPMSs.

MAIN OUTCOMES AND MEASURES

Injuries and diagnoses, treating services, procedures, hospital care, and monetary charges.

RESULTS

Among the 403 individuals included in the study, the median age was 33.0 (IQR, 24.5-48.0 [range, 1 to >89]) years, and 209 (51.9%) were women. Among the 386 patients with race and ethnicity data available, 13 (3.4%) were Asian; 44 (11.4%), Black or African American; 59 (15.3), Hispanic/Latinx; and 270 (69.9%), White. Injuries included 252 gunshot wounds (62.5%) and 112 other injuries (27.8%), and 39 patients (9.7%) had no physical injuries. One hundred seventy-eight individuals (53.1%) arrived by ambulance. Of 494 body regions injured (mean [SD], 1.35 [0.68] per patient), most common included an extremity (282 [57.1%]), abdomen and/or pelvis (66 [13.4%]), head and/or neck (65 [13.2%]), and chest (50 [10.1%]). Overall, 147 individuals (36.5%) were admitted to a hospital, 95 (23.6%) underwent 1 surgical procedure, and 42 (10.4%) underwent multiple procedures (1.82 per patient). Among the 252 patients with gunshot wounds, the most common initial procedures were general and trauma surgery (41 [16.3%]) and orthopedic surgery (36 [14.3%]). In the emergency department, 148 of 364 injured individuals (40.7%) had 199 procedures (1.34 per patient). Median hospital length of stay was 4.0 (IQR, 2.0-7.5) days; for 50 patients in the intensive care unit, 3.0 (IQR, 2.0-8.0) days (13.7% of injuries and 34.0% of admissions). Among 364 injured patients, 160 (44.0%) had functional disability at discharge, with 19 (13.3%) sent to long-term care. The mean (SD) charges per patient were $64 976 ($160 083).

CONCLUSIONS AND RELEVANCE

Civilian public mass shootings cause substantial morbidity. For every death, 5.8 individuals are injured. These results suggest that including nonfatal injuries in the overall burden of CPMSs may help inform public policy to prevent and mitigate the harm caused by such events.

Impact of time to surgery on mortality in hypotensive patients with noncompressible torso hemorrhage: An AAST multicenter, prospective study

BACKGROUND

Death from noncompressible torso hemorrhage (NCTH) may be preventable with improved prehospital care and shorter in-hospital times to hemorrhage control. We hypothesized that shorter times to surgical intervention for hemorrhage control would decrease mortality in hypotensive patients with NCTH.

METHODS

This was an AAST-sponsored multicenter, prospective analysis of hypotensive patients aged 15+ years who presented with NCTH from May 2018 to December 2020. Hypotension was defined as an initial systolic blood pressure (SBP) ≤ 90 mm Hg. Primary outcomes of interest were time to surgical intervention and in-hospital mortality.

RESULTS

There were 242 hypotensive patients, of which 48 died (19.8%). Nonsurvivors had higher mean age (47.3 vs. 38.8; p = 0.02), higher mean New Injury Severity Score (38 vs. 29; p < 0.001), lower admit systolic blood pressure (68 vs. 79 mm Hg; p < 0.01), higher incidence of vascular injury (41.7% vs. 21.1%; p = 0.02), and shorter median (interquartile range, 25-75) time from injury to operating room start (74 minutes [48-98 minutes] vs. 88 minutes [61-128 minutes]; p = 0.03) than did survivors. Multivariable Cox regression showed shorter time from emergency department arrival to operating room start was not associated with improved survival (p = 0.04).

CONCLUSION

Patients who died arrived to a trauma center in a similar time frame as did survivors but presented in greater physiological distress and had significantly shorter times to surgical hemorrhage intervention than did survivors. This suggests that even expediting a critically ill patient through the current trauma system is not sufficient time to save lives from NCTH. Civilian prehospital advance resuscitative care starting from the patient first contact needs special consideration.

Charges, length of stay, and complication associations with trauma center ownership in adult patients with mild to moderate trauma

BACKGROUND

For-profit (FP) trauma centers (TCs) charge more for trauma care than not-for-profit (NFP) centers. We sought to determine charges, length of stay (LOS), and complications associations with TC ownership status (FP, NFP, and government) for three diagnoses among patients with overall low injury severity.

METHODS

Adult patients treated at TCs with an International Classification of Diseases-based injury severity score (ICISS) survival probability ≥ 0.85 were identified. Only those who with a principal diagnosis of femur, tibial or rib fractures were included.

RESULTS

Total charges were significantly higher at FP centers than NFP and lower at government centers (89.6% and -12.8%, respectively). FP TCs had a 12.5% longer LOS and government TCs had a 20.4% longer LOS than NFP TCs.

CONCLUSION

Patients presenting to FP TCs with mild/moderate femur, tibial, or rib fractures experienced higher charges and increased LOS compared with government or NFP centers. There was no difference in overall complication rates.

Serial hemoglobin monitoring in adult patients with blunt solid organ injury: less is more

Background

Patients who sustain blunt solid organ injury to the liver, spleen, or kidney and are treated nonoperatively frequently undergo serial monitoring of their hemoglobin (Hb). We hypothesized that among initially hemodynamically stable patients with blunt splenic, hepatic, or renal injuries treated without an operation, scheduled monitoring of serum Hb values may be unnecessary as hemodynamic instability, not merely Hb drop, would prompt intervention.

Methods

We performed a retrospective review of patients admitted to our urban Level 1 trauma center following blunt trauma with any grade III, IV, or V liver, spleen, or kidney injury from January 1, 2016 to December 31, 2016. Patients who were hemodynamically unstable and went directly to the operating room or interventional radiology were excluded. Patients who required any urgent or unplanned operative or angiographic intervention were compared with patients who did not require an intervention. Routine demographic and outcome variables were obtained and bivariate and multivariate regression statistics were performed using Stata V.10.

Results

A total of 138 patients were included in the study. Age (39.3 vs 41.4, p=0.51), mean injury severity score (26.7 vs 22.1, p=0.12), and admission Hb (11.9 vs 12.8, p=0.06) did not differ significantly between the two groups. The number of Hb draws (9.2 vs 10, p=0.69) and the associated change in Hb (3.7 vs 3.5, p=0.71) did not differ significantly between the two groups. Only splenic grade predicted need for urgent intervention (3.5 vs 2, p<0.001). All patients who required an operative or radiologic intervention did so based on change in hemodynamics or severity of splenic grade, per our institutional protocol, and not Hb trend.

Discussion

Among patients with blunt solid organ injury, a need for emergent intervention in the form of laparotomy or angioembolization occurs within the first hours of injury. Routine scheduled Hb measurements did not change management in our cohort.

Postsurgical prescriptions for opioid naive patients and association with overdose and misuse: retrospective cohort study

OBJECTIVE

To quantify the effects of varying opioid prescribing patterns after surgery on dependence, overdose, or abuse in an opioid naive population.

DESIGN

Retrospective cohort study.

SETTING

Surgical claims from a linked medical and pharmacy administrative database of 37 651 619 commercially insured patients between 2008 and 2016.

PARTICIPANTS

1 015 116 opioid naive patients undergoing surgery.

MAIN OUTCOME MEASURES

Use of oral opioids after discharge as defined by refills and total dosage and duration of use. The primary outcome was a composite of misuse identified by a diagnostic code for opioid dependence, abuse, or overdose.

RESULTS

568 612 (56.0%) patients received postoperative opioids, and a code for abuse was identified for 5906 patients (0.6%, 183 per 100 000 person years). Total duration of opioid use was the strongest predictor of misuse, with each refill and additional week of opioid use associated with an adjusted increase in the rate of misuse of 44.0% (95% confidence interval 40.8% to 47.2%, P<0.001), and 19.9% increase in hazard (18.5% to 21.4%, P<0.001), respectively.

CONCLUSIONS

Each refill and week of opioid prescription is associated with a large increase in opioid misuse among opioid naive patients. The data from this study suggest that duration of the prescription rather than dosage is more strongly associated with ultimate misuse in the early postsurgical period. The analysis quantifies the association of prescribing choices on opioid misuse and identifies levers for possible impact.

Geographic Distribution of Trauma Burden, Mortality, and Services in the United States: Does Availability Correspond to Patient Need?

BACKGROUND

The association between the need for trauma care and trauma services has not been characterized previously. We compared the distribution of trauma admissions with state-level availability of trauma centers (TCs), surgical critical care (SCC) providers, and SCC fellowships, and assessed the association between trauma care provision and state-level trauma mortality.

STUDY DESIGN

We obtained 2013 state-level data on trauma admissions, TCs, SCC providers, SCC fellowship positions, per-capita income, population size, and age-adjusted mortality rates. Normalized densities (per million population [PMP]) were calculated and generalized linear models were used to test associations between provision of trauma services (higher-level TCs, SCC providers, and SCC fellowship positions) and trauma burden, per-capita income, and age-adjusted mortality rates.

RESULTS

There were 1,345,024 trauma admissions (4,250 PMP), 2,496 SCC providers (7.89 PMP), and 1,987 TCs across the country, of which 521 were Level I or II (1.65 PMP). There was considerable variation between the top 5 and bottom 5 states in terms of Level I/Level II TCs and SCC surgeon availability (approximately 8.0/1.0), despite showing less variation in trauma admission density (1.5/1.0). Distribution of trauma admissions was positively associated with SCC provider density and age-adjusted trauma mortality (p ≤ 0.001), and inversely associated with per-capita income (p < 0.001). Age-adjusted mortality was inversely associated with the number of SCC providers PMP. For every additional SCC provider PMP, there was a decrease of 618 deaths per year.

CONCLUSIONS

There is an inequitable distribution of trauma services across the US. Increases in the density of SCC providers are associated with decreases in mortality. There was no association between density of trauma admissions and location of Level I/Level II TCs. In the wake of efforts to regionalize TCs, additional efforts are needed to address disparities in the provision of quality care to trauma patients.
