A tale of two cities: Policing and firearm homicides in Boston and Philadelphia

BACKGROUND

Recent political movements have raised questions about the effectiveness of police funding, but the impact of law enforcement budgets on firearm violence is unknown. We hypothesized that department funding and measures of police activity would be associated with decreased shootings and firearm homicides (FHs) in two major cities with different police funding patterns.

METHODS

We collected data from the following sources: district attorney's offices, police departments, Federal Bureau of Investigation Uniform Crime Reporting program, the Centers for Disease Control, the Annual Survey of Public Employment and Payroll, and the American Community Survey. Data included demographics, police department budgets, number of officers, homicide clearance rates, firearms recovered, shootings, and FHs, 2015 to 2020. Totals were normalized to population and number of shootings. We used panel linear regression to measure associations between policing variables, shootings, and FHs while adjusting for covariates.

RESULTS

Firearm homicides significantly increased in Philadelphia. In Boston, the trend was less clear, although there was an increase in 2020. Police budget normalized to shootings trended toward a decrease in Philadelphia and an increase in Boston. The number of firearms recovered annually appeared to increase in Boston but peaked midstudy in Philadelphia. In multivariable analyses, police budget was associated with neither shootings nor FHs. However, increased firearm recovery was associated with lower shooting ( β = -0.0004, p = 0.022) and FH ( β = -0.00005, p = 0.004) rates.

CONCLUSION

Philadelphia and Boston demonstrated differences in police funding, 2015 to 2020. While budget is not associated with shootings or FHs, firearm recovery is suggesting that removal of firearms from circulation remains key. The impact this has on vulnerable populations requires further investigation.

Loss of independence after traumatic injury: A patient-centered study

BACKGROUND

Patient-reported outcomes of postdischarge functional status can provide insight into patient recovery experiences not typically reflected in trauma registries. Injuries may be characterized by a long-term loss of independence. We sought to examine factors predictive of patient-reported, postdischarge loss of independence in trauma patients.

METHODS

Trauma patients admitted to 1 of 3 level I trauma centers were contacted by phone between 6 to 12 months after hospital discharge to complete the Revised Trauma Quality of Life survey. Loss of independence was defined as a new need for assistance with at least one activity of daily living or transition to living in an institutional setting. Patients with severe traumatic brain injury or spinal cord injury were excluded. Multivariable logistic regression analyses were performed to identify predictors of loss of independence.

RESULTS

801 patients were included. The median age was 65 (interquartile range: 46-76) years, 46.1% were female, and the median Injury Severity Score was 9 (interquartile range: 9-13). Two hundred seventy-one patients (33.8%) experienced a loss of independence, most commonly requiring assistance walking up stairs. The main predictors of loss of independence were persistent daily pain (odds ratio: 3.83, 95% confidence interval: [2.90-5.04], P < .001), length of hospital stay (odds ratio: 1.04, 95% confidence interval: [1.01-1.09], P = .021) and income below the national median (odds ratio: 1.46, 95% confidence interval: [1.12-1.91], P = .006). Perceived social support (odds ratio: 0.75, 95% confidence interval: [0.66-0.85], P < .001) was protective against loss of independence.

CONCLUSION

Injury is associated with a relatively high rate of long-term loss of independence. Ensuring adequate social support systems for patients postdischarge may help them regain functional independence after injury.

Trial Participation and Outcomes Among English-Speaking and Spanish-Speaking Patients With Appendicitis Randomized to Antibiotics: A Secondary Analysis of the CODA Randomized Clinical Trial

Importance

Spanish-speaking participants are underrepresented in clinical trials, limiting study generalizability and contributing to ongoing health inequity. The Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial intentionally included Spanish-speaking participants.

Objective

To describe trial participation and compare clinical and patient-reported outcomes among Spanish-speaking and English-speaking participants with acute appendicitis randomized to antibiotics.

Design, Setting, and Participants

This study is a secondary analysis of the CODA trial, a pragmatic randomized trial comparing antibiotic therapy with appendectomy in adult patients with imaging-confirmed appendicitis enrolled at 25 centers across the US from May 1, 2016, to February 28, 2020. The trial was conducted in English and Spanish. All 776 participants randomized to antibiotics are included in this analysis. The data were analyzed from November 15, 2021, through August 24, 2022.

Intervention

Randomization to a 10-day course of antibiotics or appendectomy.

Main Outcomes and Measures

Trial participation, European Quality of Life-5 Dimensions (EQ-5D) questionnaire scores (higher scores indicating a better health status), rate of appendectomy, treatment satisfaction, decisional regret, and days of work missed. Outcomes are also reported for a subset of participants that were recruited from the 5 sites with a large proportion of Spanish-speaking participants.

Results

Among eligible patients 476 of 1050 Spanish speakers (45%) and 1076 of 3982 of English speakers (27%) consented, comprising the 1552 participants who underwent 1:1 randomization (mean age, 38.0 years; 976 male [63%]). Of the 776 participants randomized to antibiotics, 238 were Spanish speaking (31%). Among Spanish speakers randomized to antibiotics, the rate of appendectomy was 22% (95% CI, 17%-28%) at 30 days and 45% (95% CI, 38%-52%) at 1 year, while in English speakers, these rates were 20% (95% CI, 16%-23%) at 30 days and 42% (95% CI 38%-47%) at 1 year. Mean EQ-5D scores were 0.93 (95% CI, 0.92-0.95) among Spanish speakers and 0.92 (95% CI, 0.91-0.93) among English speakers. Symptom resolution at 30 days was reported by 68% (95% CI, 61%-74%) of Spanish speakers and 69% (95% CI, 64%-73%) of English speakers. Spanish speakers missed 6.69 (95% CI, 5.51-7.87) days of work on average, while English speakers missed 3.76 (95% CI, 3.20-4.32) days. Presentation to the emergency department or urgent care, hospitalization, treatment dissatisfaction, and decisional regret were low for both groups.

Conclusions and Relevance

A high proportion of Spanish speakers participated in the CODA trial. Clinical and most patient-reported outcomes were similar for English- and Spanish-speaking participants treated with antibiotics. Spanish speakers reported more days of missed work.

Injury-related emergency department visits and unplanned readmissions are associated with worse long-term mental and physical health

BACKGROUND

The risk factors for unplanned emergency department (ED) visits and readmission after injury and the impact of these unplanned visits on long-term outcomes are not well understood. We aim to: 1) describe the incidence of and risk factors for injury-related ED visits and unplanned readmissions following injury and, 2) explore the relationship between these unplanned visits and mental and physical health outcomes 6-12 months post-injury.

METHODS

Trauma patients with moderate-to-severe injury admitted to one of three Level-I trauma centers were asked to complete a phone survey to assess mental and physical health outcomes at 6-12 months. Patient reported data on injury-related ED visits and readmissions was collected. Multivariable regression analyses were performed controlling for sociodemographic and clinical variables to compare subgroups.

RESULTS

Of 7,781 eligible patients, 4675 were contacted and 3,147 completed the survey and were included in the analysis. 194 (6.2%) reported an unplanned injury-related ED visit and 239 (7.6%) reported an injury-related readmission. Risk factors for injury-related ED visits included: younger age, Black race, a lower level of education, Medicaid insurance, baseline psychiatric or substance abuse disorder and penetrating mechanism. Risk factors for unplanned injury-related readmission included younger age, male sex, Medicaid insurance, substance abuse disorder, greater injury severity and penetrating mechanism of injury. Injury-related ED visits and readmissions were associated with significantly higher rates of PTSD, chronic pain and new injury-related functional limitations in addition to lower SF-12 mental and physical composite scores.

CONCLUSIONS

Injury-related ED visits and unplanned readmissions are common after hospital discharge following treatment of moderate-severe injury and are associated with worse mental and physical health outcomes.

History repeats itself: Impact of mental illness on violent reinjury and hospital reencounters among female victims of interpersonal violence

BACKGROUND

Violence-related reinjury impacts both patients and health care systems. Mental illness (MI) is prevalent among violently injured individuals. The relationship between preexisting MI and violent reinjury among women has not been fully characterized. Our objective was to determine if risk of hospital reencounter-violent reinjury and all-cause-was associated with preexisting MI at time of index injury among female victims of violence.

METHODS

All females (15-100 + years) presenting to a level I trauma center with violent injury (2002-2019) surviving to discharge were included (N = 1,056). Exposure was presence of preexisting MI. The primary outcome was hospital reencounters for violent reinjury and all-cause within one year (through 2020). The secondary outcome was the development of a new MI within one year of index injury. Odds of reencounter and development of new MI for those with and without preexisting MI were compared with multivariable logistic regression, stratified for interaction when appropriate.

RESULTS

There were 404 women (38%) with preexisting MI at time of index injury. Approximately 11% of patients with preexisting MI experienced violent reinjury compared to 5% of those without within 1 year ( p < 0.001). Specifically, those with MI in the absence of concomitant substance use had more than three times the odds of violent reinjury (adjusted Odds Ratio, 3.52 (1.57, 7.93); p = 0.002). Of those with preexisting MI, 64% had at least one reencounter for any reason compared to 46% of those without ( p < 0.001 ) . Odds of all-cause reencounter for those with preexisting MI were nearly twice of those without (adjusted Odds Ratio, 1.81 [1.36, 2.42]; p < 0.0001).

CONCLUSION

Among female victims of violence, preexisting MI is associated with a significantly increased risk of hospital reencounter and violent reinjury within the first year after index injury. Recognition of this vulnerable population and improved efforts at addressing MI in trauma patients is critical to ongoing prevention efforts to reduce violent reinjury.

Perception of Treatment Success and Impact on Function with Antibiotics or Appendectomy for Appendicitis: A Randomized Clinical Trial with an Observational Cohort

OBJECTIVE

To compare secondary patient reported outcomes of perceptions of treatment success and function for patients treated for appendicitis with appendectomy vs. antibiotics at 30 days.

SUMMARY BACKGROUND DATA

The Comparison of Outcomes of antibiotic Drugs and Appendectomy trial found antibiotics noninferior to appendectomy based on 30-day health status. To address questions about outcomes among participants with lower socioeconomic status, we explored the relationship of sociodemographic and clinical factors and outcomes.

METHODS

We focused on 4 patient reported outcomes at 30 days: high decisional regret, dissatisfaction with treatment, problems performing usual activities, and missing >10 days of work. The randomized (RCT) and observational cohorts were pooled for exploration of baseline factors. The RCT cohort alone was used for comparison of treatments. Logistic regression was used to assess associations.

RESULTS

The pooled cohort contained 2062 participants; 1552 from the RCT. Overall, regret and dissatisfaction were low whereas problems with usual activities and prolonged missed work occurred more frequently. In the RCT, those assigned to antibiotics had more regret (Odd ratios (OR) 2.97, 95% Confidence intervals (CI) 2.05-4.31) and dissatisfaction (OR 1.98, 95%CI 1.25-3.12), and reported less missed work (OR 0.39, 95%CI 0.27-0.56). Factors associated with function outcomes included sociodemographic and clinical variables for both treatment arms. Fewer factors were associated with dissatisfaction and regret.

CONCLUSIONS

Overall, participants reported high satisfaction, low regret, and were frequently able to resume usual activities and return to work. When comparing treatments for appendicitis, no single measure defines success or failure for all people. The reported data may inform discussions regarding the most appropriate treatment for individuals.

PICLN modulates alternative splicing and light/temperature responses in plants

Plants undergo transcriptome reprograming to adapt to daily and seasonal fluctuations in light and temperature conditions. While most efforts have focused on the role of master transcription factors, the importance of splicing factors modulating these processes is now emerging. Efficient pre-mRNA splicing depends on proper spliceosome assembly, which in plants and animals requires the methylosome complex. Ion Chloride nucleotide-sensitive protein (PICLN) is part of the methylosome complex in both humans and Arabidopsis (Arabidopsis thaliana), and we show here that the human PICLN ortholog rescues phenotypes of Arabidopsis picln mutants. Altered photomorphogenic and photoperiodic responses in Arabidopsis picln mutants are associated with changes in pre-mRNA splicing that partially overlap with those in PROTEIN ARGININE METHYL TRANSFERASE5 (prmt5) mutants. Mammalian PICLN also acts in concert with the Survival Motor Neuron (SMN) complex component GEMIN2 to modulate the late steps of UsnRNP assembly, and many alternative splicing events regulated by PICLN but not PRMT5, the main protein of the methylosome, are controlled by Arabidopsis GEMIN2. As with GEMIN2 and SM PROTEIN E1/PORCUPINE (SME1/PCP), low temperature, which increases PICLN expression, aggravates morphological and molecular defects of picln mutants. Taken together, these results establish a key role for PICLN in the regulation of pre-mRNA splicing and in mediating plant adaptation to daily and seasonal fluctuations in environmental conditions.

Utilization of torso computed tomography for the evaluation of ground level falls: More imaging does not equal better care

INTRODUCTION

Computed tomography (CT) of the chest (CTC), abdomen, and pelvis (CTAP) is common when assessing trauma patients in the emergency department. However, unnecessary imaging can expose patients to unneeded radiation and increase healthcare costs. Here, we characterize the use of torso CT imaging for the evaluation of ground level falls (GLF) at a single level 1 trauma center.

PATIENTS AND METHODS

We conducted a retrospective review of all patients ≥18 years old presenting to a single level 1 trauma center with a GLF (1m or less) in 2015-2019. Data were obtained through chart review. Descriptive statistics were used to summarize patient characteristics. Multivariable logistic regression was used to assess factors leading to patients obtaining torso CT imaging. The utility of CT imaging in identifying injuries that changed management was also evaluated.

RESULTS

Of the 1,195 patients captured during the study period, 492 patients had a positive torso physical exam (PE), and 703 had a negative torso PE. Of patients with a negative torso PE, 127 CTC and 142 CTAP were obtained, with only 5.5% CTC identifying traumatic injuries not previously diagnosed on chest radiograph (CXR), and only 0.7% CTAP identifying new injuries not identified on pelvic radiograph (PXR). Multivariable logistic regression demonstrated that only a positive PE was significantly associated with the identification of abnormal imaging findings on torso CT. A negative PE, CXR, and PXR have a negative predictive value of 98%.

DISCUSSION

These data suggest that patients with a negative PE, even if intoxicated, intubated, or with a decreased GCS, are highly unlikely to have new, clinically relevant findings on torso CT imaging.

CONCLUSION

Using PE, CXR, and PXR as a screening tool in patients sustaining GLF, which if negative close to obviates the need for torso CT, may reduce healthcare costs and radiation exposure without compromising patient care.

Intersection of Race, Ethnicity, and Sex in New Functional Limitations after Injury: Black and Hispanic Female Survivors at Greater Risk

BACKGROUND

The impact of disparities at the intersection of multiple marginalized social identities is poorly understood in trauma. We sought to evaluate the joint effect of race, ethnicity, and sex on new functional limitations 6 to 12 months postinjury.

STUDY DESIGN

Moderately to severely injured patients admitted to one of three Level I trauma centers were asked to complete a phone-based survey assessing functional outcomes 6 to 12 months postinjury. Multivariate adjusted regression analyses were used to compare functional limitations by race and ethnicity alone, sex alone, and the interaction between both race and ethnicity and sex. The joint disparity and its composition were calculated across race and sex strata.

RESULTS

Included were 4,020 patients: 1,621 (40.3%) non-Hispanic White male patients, 1,566 (39%) non-Hispanic White female patients, 570 (14.2%) Black or Hispanic/Latinx male patients, and 263 (6.5%) Black or Hispanic/Latinx female patients (BHF). The risk-adjusted incidence of functional limitations was highest among BHF (50.6%) vs non-Hispanic White female patients (39.2%), non-Hispanic White male patients (35.8%), and Black or Hispanic male patients (34.6%; p < 0.001). In adjusted analysis, women (odds ratio 1.35 [95% CI 1.16 to 1.57]; p < 0.001) and Blacks or Hispanic patients (odds ratio 1.28 [95% CI 1.03 to 1.58]; p = 0.02) were more likely to have new functional limitations 6 to 12 months postinjury. When sex and race were analyzed together, BHF were more likely to have new functional limitations compared with non-Hispanic White male patients (odds ratio 2.12 [1.55 to 2.90]; p < 0.001), with 63.5% of this joint disparity being explained by the intersection of race and ethnicity and sex.

CONCLUSION

More than half of the race and sex disparity in functional limitations experienced by BHF is explained by the unique experience of being both minority and a woman. Intermediate modifiable factors contributing to this intersectional disparity must be identified.

Association of Patient Belief About Success of Antibiotics for Appendicitis and Outcomes: A Secondary Analysis of the CODA Randomized Clinical Trial

Importance

A patient's belief in the likely success of a treatment may influence outcomes, but this has been understudied in surgical trials.

Objective

To examine the association between patients' baseline beliefs about the likelihood of treatment success with outcomes of antibiotics for appendicitis in the Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial.

Design, Setting, and Participants

This was a secondary analysis of the CODA randomized clinical trial. Participants from 25 US medical centers were enrolled between May 3, 2016, and February 5, 2020. Included in the analysis were participants with appendicitis who were randomly assigned to receive antibiotics in the CODA trial. After informed consent but before randomization, participants who were assigned to receive antibiotics responded to a baseline survey including a question about how successful they believed antibiotics could be in treating their appendicitis.

Interventions

Participants were categorized based on baseline survey responses into 1 of 3 belief groups: unsuccessful/unsure, intermediate, and completely successful.

Main Outcomes and Measures

Three outcomes were assigned at 30 days: (1) appendectomy, (2) high decisional regret or dissatisfaction with treatment, and (3) persistent signs and symptoms (abdominal pain, tenderness, fever, or chills). Outcomes were compared across groups using adjusted risk differences (aRDs), with propensity score adjustment for sociodemographic and clinical factors.

Results

Of the 776 study participants who were assigned antibiotic treatment in CODA, a total of 425 (mean [SD] age, 38.5 [13.6] years; 277 male [65%]) completed the baseline belief survey before knowing their treatment assignment. Baseline beliefs were as follows: 22% of participants (92 of 415) had an unsuccessful/unsure response, 51% (212 of 415) had an intermediate response, and 27% (111 of 415) had a completely successful response. Compared with the unsuccessful/unsure group, those who believed antibiotics could be completely successful had a 13-percentage point lower risk of appendectomy (aRD, -13.49; 95% CI, -24.57 to -2.40). The aRD between those with intermediate vs unsuccessful/unsure beliefs was -5.68 (95% CI, -16.57 to 5.20). Compared with the unsuccessful/unsure group, those with intermediate beliefs had a lower risk of persistent signs and symptoms (aRD, -15.72; 95% CI, -29.71 to -1.72), with directionally similar results for the completely successful group (aRD, -15.14; 95% CI, -30.56 to 0.28).

Conclusions and Relevance

Positive patient beliefs about the likely success of antibiotics for appendicitis were associated with a lower risk of appendectomy and with resolution of signs and symptoms by 30 days. Pathways relating beliefs to outcomes and the potential modifiability of beliefs to improve outcomes merit further investigation.

Caveat emptor: The accuracy of claims data in appendicitis research

BACKGROUND

International Classification of Disease, ninth/tenth revision codes are used to identify patients with appendicitis and classify severity of disease for research and hospital reimbursement. We sought to determine accuracy of International Classification of Disease, ninth/tenth revision codes in classifying appendicitis as uncomplicated versus complicated (defined as perforated, necrotic, or abscess) compared with the clinical gold standard: surgeon characterization of the appendix in the operative report.

METHODS

Retrospective review of operative reports and discharge International Classification of Disease, ninth/tenth revision codes for patients ≥18 years old who underwent noninterval, nonincidental appendectomy between January 2012 and December 2019 at a tertiary referral center. Sensitivity, specificity, and positive predictive value were calculated for International Classification of Disease, ninth/tenth revision codes to classify appendicitis accurately as complicated compared with surgeon description. ICD-9/10 codes and surgeon description were categorized into complicated/uncomplicated based on the American Association for the Surgery of Trauma grading system.

RESULTS

In the study, 1,495 patients with acute appendicitis underwent appendectomy. Per surgeon description, 200 (13%) were complicated and 1,295 (87%) uncomplicated. Compared with surgeon description, discharge International Classification of Disease, ninth/tenth revision codes did not accurately identify complicated appendicitis: sensitivity = 0.68, positive predictive value = 0.77. As a sensitivity analysis, the cohort was stratified by public versus private payers, and the results did not change.

CONCLUSION

International Classification of Disease, ninth/tenth revision codes do not accurately identify surgeon-described complicated appendicitis. Nearly one-third of the cases of complicated appendicitis were coded as uncomplicated. Such misclassification negatively impacts reimbursement for complicated appendicitis care and could lead to misleading results in research and quality improvement activities that rely on these codes.

Analysis of Outcomes Associated With Outpatient Management of Nonoperatively Treated Patients With Appendicitis

IMPORTANCE

In the Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial, which found antibiotics to be noninferior, approximately half of participants randomized to receive antibiotics had outpatient management with hospital discharge within 24 hours. If outpatient management is safe, it could increase convenience and decrease health care use and costs.

OBJECTIVE

To assess the use and safety of outpatient management of acute appendicitis.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study, which is a secondary analysis of the CODA trial, included 776 adults with imaging-confirmed appendicitis who received antibiotics at 25 US hospitals from May 1, 2016, to February 28, 2020.

EXPOSURES

Participants randomized to antibiotics (intravenous then oral) could be discharged from the emergency department based on clinician judgment and prespecified criteria (hemodynamically stable, afebrile, oral intake tolerated, pain controlled, and follow-up confirmed). Outpatient management and hospitalization were defined as discharge within or after 24 hours, respectively.

MAIN OUTCOMES AND MEASURES

Outcomes compared among patients receiving outpatient vs inpatient care included serious adverse events (SAEs), appendectomies, health care encounters, satisfaction, missed workdays at 7 days, and EuroQol 5-dimension (EQ-5D) score at 30 days. In addition, appendectomy incidence among outpatients and inpatients, unadjusted and adjusted for illness severity, was compared.

RESULTS

Among 776 antibiotic-randomized participants, 42 (5.4%) underwent appendectomy within 24 hours and 8 (1.0%) did not receive their first antibiotic dose within 24 hours, leaving 726 (93.6%) comprising the study population (median age, 36 years; range, 18-86 years; 462 [63.6%] male; 437 [60.2%] White). Of these participants, 335 (46.1%; site range, 0-89.2%) were discharged within 24 hours, and 391 (53.9%) were discharged after 24 hours. Over 7 days, SAEs occurred in 0.9 (95% CI, 0.2-2.6) per 100 outpatients and 1.3 (95% CI, 0.4-2.9) per 100 inpatients; in the appendicolith subgroup, SAEs occurred in 2.3 (95% CI, 0.3-8.2) per 100 outpatients vs 2.8 (95% CI, 0.6-7.9) per 100 inpatients. During this period, appendectomy occurred in 9.9% (95% CI, 6.9%-13.7%) of outpatients and 14.1% (95% CI, 10.8%-18.0%) of inpatients; adjusted analysis demonstrated a similar difference in incidence (-4.0 percentage points; 95% CI, -8.7 to 0.6). At 30 days, appendectomies occurred in 12.6% (95% CI, 9.1%-16.7%) of outpatients and 19.0% (95% CI, 15.1%-23.4%) of inpatients. Outpatients missed fewer workdays (2.6 days; 95% CI, 2.3-2.9 days) than did inpatients (3.8 days; 95% CI, 3.4-4.3 days) and had similar frequency of return health care visits and high satisfaction and EQ-5D scores.

CONCLUSIONS AND RELEVANCE

These findings support that outpatient antibiotic management is safe for selected adults with acute appendicitis, with no greater risk of complications or appendectomy than hospital care, and should be included in shared decision-making discussions of patient preferences for outcomes associated with nonoperative and operative care.

Self-selection vs Randomized Assignment of Treatment for Appendicitis

Importance

For adults with appendicitis, several randomized clinical trials have demonstrated that antibiotics are an effective alternative to appendectomy. However, it remains unknown how the characteristics of patients in such trials compare with those of patients who select their treatment and whether outcomes differ.

Objective

To compare participants in the Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) randomized clinical trial (RCT) with a parallel cohort study of participants who declined randomization and self-selected treatment.

Design, Setting, and Participants

The CODA trial was conducted in 25 US medical centers. Participants were enrolled between May 3, 2016, and February 5, 2020; all participants were eligible for at least 1 year of follow-up, with all follow-up ending in 2021. The randomized cohort included 1094 adults with appendicitis; the self-selection cohort included patients who declined participation in the randomized group, of whom 253 selected appendectomy and 257 selected antibiotics. In this secondary analysis, characteristics and outcomes in both self-selection and randomized cohorts are described with an exploratory analysis of cohort status and receipt of appendectomy.

Interventions

Appendectomy vs antibiotics.

Main Outcomes and Measures

Characteristics among participants randomized to either appendectomy or antibiotics were compared with those of participants who selected their own treatment.

Results

Clinical characteristics were similar across the self-selection cohort (510 patients; mean age, 35.8 years [95% CI, 34.5-37.1]; 218 female [43%; 95% CI, 39%-47%]) and the randomized group (1094 patients; mean age, 38.2 years [95% CI, 37.4-39.0]; 386 female [35%; 95% CI, 33%-38%]). Compared with the randomized group, those in the self-selection cohort were less often Spanish speaking (n = 99 [19%; 95% CI, 16%-23%] vs n = 336 [31%; 95% CI, 28%-34%]), reported more formal education (some college or more, n = 355 [72%; 95% CI, 68%-76%] vs n = 674 [63%; 95% CI, 60%-65%]), and more often had commercial insurance (n = 259 [53%; 95% CI, 48%-57%] vs n = 486 [45%; 95% CI, 42%-48%]). Most outcomes were similar between the self-selection and randomized cohorts. The number of patients undergoing appendectomy by 30 days was 38 (15.3%; 95% CI, 10.7%-19.7%) among those selecting antibiotics and 155 (19.2%; 95% CI, 15.9%-22.5%) in those who were randomized to antibiotics (difference, 3.9%; 95% CI, -1.7% to 9.5%). Differences in the rate of appendectomy were primarily observed in the non-appendicolith subgroup.

Conclusions and Relevance

This secondary analysis of the CODA RCT found substantially similar outcomes across the randomized and self-selection cohorts, suggesting that the randomized trial results are generalizable to the community at large.

Citizenship and Social Responsibility in Surgery: A Review

Importance

Social determinants of health have been shown to be key drivers of disparities in access to surgical care and surgical outcomes. Though the concept of social responsibility has received growing attention in the medical field, little has been published contextualizing social responsibility in surgery. In this narrative review, we define social responsibility as it relates to surgery, explore the duty of surgeons to society, and provide examples of social factors associated with adverse surgical outcomes and how they can be mitigated.

Observations

The concept of social responsibility in surgery has deep roots in medical codes of ethics and evolved alongside changing views on human rights and the role of social factors in disease. The ethical duty of surgeons to society is based on the ethical principles of benevolence and justice and is grounded within the framework of the social contract. Surgeons have a responsibility to understand how factors such as patient demographics, the social environment, clinician awareness, and the health care system are associated with inequitable patient outcomes. Through education, we can empower surgeons to advocate for their patients, address the causes and consequences of surgical disparities, and incorporate social responsibility into their daily practice.

Conclusions and Relevance

One of the greatest challenges in the field of surgery is ensuring that surgical care is provided in an equitable and sustainable way. Surgeons have a duty to understand the factors that lead to health care disparities and use their knowledge, skills, and privileged position to address these issues at the individual and societal level.

Impact of COVID-19 on outcomes after trauma the impact of the COVID-19 pandemic on functional and mental health outcomes after trauma

Background

The COVID-19 pandemic has led to decreased access to care and social isolation, which have the potential for negative psychophysical effects. We examine the impact of the pandemic on physical and mental health outcomes after trauma.

Methods

Patients in a prospective study were included. The cohort injured during the pandemic was compared to a cohort injured before the pandemic. We performed regression analyses to evaluate the association between the COVID-19 pandemic and physical and mental health outcomes.

Results

1,398 patients were included. In adjusted analysis, patients injured during the pandemic scored significantly worse on the SF-12 physical composite score (OR 2.21; [95% CI 0.69–3.72]; P = 0.004) and were more likely to screen positive for depression (OR 1.46; [1.02–2.09]; P = 0.03) and anxiety (OR 1.56; [1.08–2.26]; P = 0.02). There was no significant difference in functional outcomes.

Conclusions

Patients injured during the COVID-19 pandemic had worse mental health outcomes but not physical health outcomes.

State firearm laws and nonfatal firearm injury-related inpatient hospitalizations: A nationwide panel study

BACKGROUND

Firearm injury remains a major cause of morbidity and mortality in the United States. Because of prior lack of comprehensive data sources, there is a paucity of literature on nonfatal firearm injury. Associations have previously been shown between state-level firearm laws and firearm fatalities, but few studies have examined the effects of these laws on nonfatal firearm hospitalization rates. Our objective was to examine the relationship between state firearm laws and firearm injury-related hospitalization rates across all 50 states over a 17-year period.

METHODS

In this panel study design, we used fixed effects multivariate regression models to analyze the relationship between 12 laws and firearm state-level injury-related hospitalization rates from 2000 to 2016 using the RAND Corporation Inpatient Hospitalizations for Firearm Injury Database. We used difference-in-differences to determine the impact of law passage in a given state compared with those states without the law, controlling for state-level covariates. The main outcome measure was the change in annual firearm injury-related inpatient hospitalization rates after passage or repeal of a state-level firearm law.

RESULTS

Examining each law individually, passage of violent misdemeanor, permitting, firearm removal from domestic violence offenders, and 10-round limit laws were associated with significant firearm injury-related hospitalization rate reductions. Examining multiple laws in the same model, passage of violent misdemeanor laws was associated with a 19.9% (confidence interval, 11.6%-27.4%) reduction, and removal of firearms from domestic violence offenders was associated with a 17.0% (confidence interval, 9.9%-23.6%) reduction in hospitalization rates.

CONCLUSION

State laws related to preventing violent offenders from possessing firearms are associated with firearm injury-related hospitalization rate reductions. Given significant physical, mental, and social burdens of nonfatal firearm injury, determining the efficacy of firearm-related policy is critical to violence and injury prevention efforts.

Comparative Accuracy of ICD-9 vs ICD-10 Codes for Acute Appendicitis

BACKGROUND

ICD codes are used to identify patients with appendicitis and to classify disease severity for reimbursement and research purposes. We sought to compare the accuracy of ICD-9 vs ICD-10 codes in classifying appendicitis as uncomplicated vs complicated (defined as perforated, necrotic, or abscess) compared with the clinical gold standard: surgeon characterization of the appendix in the operative report.

STUDY DESIGN

This is a retrospective review of operative reports and discharge ICD-9/10 codes for patients 18 years or older who underwent noninterval, nonincidental appendectomy from January 2012 to December 2019 at a tertiary referral center. Sensitivity, specificity, and positive predictive value were calculated for ICD-9/10 codes to classify appendicitis as complicated when compared with surgeon description. Chi-square testing was used to compare agreement between ICD-9/10 codes and surgeon description.

RESULTS

A total of 1,585 patients underwent appendectomy. ICD-9 codes had higher sensitivity than ICD-10 codes for complicated appendicitis (sensitivity 0.84 and 0.54, respectively) and a similar positive predictive value (0.77 and 0.76, respectively). Overall, 91% of ICD-9 codes agreed with surgical description of disease, but 84.4% of ICD-10 codes agreed with surgical description (p < 0.01). Among cases classified as complicated by the surgeon, 84% (79/94) had an accurate ICD-9 code for complicated disease, but only 53.8% (57/106) of cases had an accurate ICD-10 code (p < 0.01).

CONCLUSIONS

Compared with ICD-9 codes, ICD-10 codes were less accurate in characterizing severity of appendicitis. The ICD-10 coding schema does not provide an accurate representation of disease severity. Until this system is improved, significant caution is needed for people who rely on these data for billing, quality improvement, and research purposes.

Social Vulnerability and COVID-19: Changes in Trauma Activations at a Safety-Net Hospital

Introduction

Following the declaration of the COVID-19 pandemic, there were reports of decreased trauma hospitalizations, although violent crime persisted. COVID-19 has had the greatest impact on minoritized and vulnerable communities. Decreases in traumatic events may not extend to these communities, given pandemic-related socioeconomic and psychological burdens that increase the risk of exposure to trauma and violence.

Materials and methods

This was a retrospective cohort study (n = 1634) of all trauma activations presenting to our institution January 1, 2020 to May 31, 2020, and same time periods in 2018 and 2019. Census tracts and associated Social Vulnerability Index quartiles were determined from patient addresses. Changes in trauma activations pre and post Massachusetts’ state-of-emergency declaration compared to a historical control were analyzed using a difference-in-differences methodology.

Results

Weekly all-cause trauma activations fell from 26.44 to 8.25 (rate ratio = 0.36 [0.26, 0.50]) postdeclaration, with significant difference-in-differences compared to a historical control (P < 0.0001). Nonviolent trauma activations significantly decreased from 21.11 to 5.17 after the declaration (rate ratio = 0.27 [0.37, 0.91]; P < 0.0001), whereas there was no significant decrease in violent injury (5.33 to 3.08 rate ratio = 0.69 [0.39, 1.22]; P = 0.20). Stratified by vulnerability, the most vulnerable quartile had an increased proportion of all-cause trauma postdeclaration and had no decrease in violent trauma activations following the declaration compared to the historical control (rate ratio = 0.84 [0.38-1.86]; P = 0.67).

Conclusions

The state-of-emergency declaration was associated with significant decreases in overall trauma, to a greater extent in nonviolent injuries. Among those living in the most socially vulnerable communities, there was no decrease in violent trauma. These findings highlight the need for violence and injury prevention programs in vulnerable communities, particularly in times of crisis.

Changes in Medical Student Perceptions of Surgery Are Sustainable Through Focused Preclinical Surgical Exposure

OBJECTIVE

Many medical students hold negative perceptions about the surgical field that deter them from pursuing surgical training. We hypothesize that these perceptions can be sustainably changed with preclinical surgical education.

DESIGN

Students were administered a 10-question survey before the educational experience, immediately after completing the experience, and 1-3 years later. Survey questions focused on perceptions about surgery. Changes in responses over time were measured and analyzed.

SETTING

The study was performed in the setting of a voluntary preclinical surgical education experience.

PARTICIPANTS

Surveys were administered to 217 first-year medical students who all participated in the preclinical surgical education experience from 2017 to 2019. Follow-up surveys were administered to all cohorts simultaneously and anonymously via email.

RESULTS

Nine of the ten questions demonstrated statistically significant changes in perceptions from pre-experience to immediately post-experience (p < 0.048). Though attenuation was seen over time, changes in perception regarding the workload and time investment of surgical training, the role of women in surgery, and the relationships between surgeons and their patients were sustained over time (p < 0.044).

CONCLUSIONS

The results indicated that our model of surgical education could effect long-term changes in negative perceptions about the surgical field. Many of these negative perceptions are highly concerning to medical students. As such, success in changing perceptions about length and difficulty of training, gender inclusivity, and patient-centered care in surgery is important in increasing student interest in the surgical field. This becomes relevant in the current climate of a nationwide shortage of surgeons and the need to better attract students to this profession.

Implementation of a Frailty Assessment and Targeted Care Interventions and Its Association with Reduced Postoperative Complications in Elderly Surgical Patients

BACKGROUND

Older patients with frailty syndrome have a greater risk of poor postoperative outcomes. In this study, we used a RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework to implement an assessment tool to identify frail patients and targeted interventions to improve their outcomes.

STUDY DESIGN

We implemented a 5-question frailty assessment tool for patients 65 years and older admitted to the general and vascular surgery services from January 1, 2018 to December 31, 2019. Identified frail patients received evidence-based clinical orders and nursing care plan interventions tailored to optimize recovery. A RE-AIM framework was used to assess implementation effectiveness through provider and nurse surveys, floor audits, and chart review.

RESULTS

Of 1,158 patients included in this study, 696 (60.1%) were assessed for frailty. Among these, 611 patients (87.8%) scored as frail or intermediately frail. After implementation, there were significant increases in the completion rates of frailty-specific care orders for frail patients, including delirium precautions (52.1% vs 30.7%; p < 0.001), aspiration precautions (50.0% vs 26.9%; p < 0.001), and avoidance of overnight vitals (32.5% vs 0%). Floor audits, however, showed high variability in completion of care plan components by nursing staff. Multivariate analysis showed significant decreases in 30-day complication rates (odds ratio 0.532; p < 0.001) after implementation.

CONCLUSIONS

A frailty assessment was able to identify elderly patients for provision of targeted, evidence-based frailty care. Despite limited uptake of the assessment by providers and completion of care plan components by nursing staff, implementation of the assessment and care interventions was associated with substantial decreases in complications among elderly surgical patients.

Patient reported outcomes 6 to 12 months after interpersonal violence: A multicenter cohort study

PURPOSE

Violence continues to be a significant public health burden, but little is known about the long-term outcomes of these patients. Our goal was to determine the impact of violence-related trauma on long-term functional and psychosocial outcomes.

METHODS

We identified trauma patients with moderate to severe injuries (Injury Severity Score, ≥9) treated at one of three level 1 trauma centers. These patients were asked to complete a survey over the phone between 6 and 12 months after injury evaluating both functional and psychosocial outcomes (12-item Short Form Survey, Trauma Quality of Life, posttraumatic stress disorder [PTSD] screen, chronic pain, return to work). Patients were classified as having suffered a violent injury if the mechanism of injury was a stab, gunshot, or assault. Self-inflicted wounds were excluded. Adjusted logistic regression models were built to determine the association between a violent mechanism of injury and long-term outcomes.

RESULTS

A total of 1,050 moderate to severely injured patients were successfully followed, of whom 176 (16.8%) were victims of violence. For the victims of violence, mean age was 34.4 years (SD, 12.5 years), 85% were male, and 57.5% were Black; 30.7% reported newly needing help with at least one activity of daily living after the violence-related event. Fifty-nine (49.2%) of 120 patients who were working before their injury had not yet returned to work; 47.1% screened positive for PTSD, and 52.3% reported chronic pain. On multivariate analysis, a violent mechanism was significantly associated with PTSD (odds ratio, 2.57; 95% confidence interval, 1.59-4.17; p < 0.001) but not associated with chronic pain, return to work, or functional outcomes.

CONCLUSION

The physical and mental health burden after violence-related trauma is not insignificant. Further work is needed to identify intervention strategies and social support systems that may be beneficial to reduce this burden.
