Investigating the Relationship Between Psychosocial Safety Climate and Mental Illness Stigma Among Emergency Medical Service Clinicians.

OBJECTIVES: To examine the relationship between psychosocial safety climate (PSC) and mental illness stigma among emergency medical service (EMS) clinicians. Despite the presence of mental health services at many EMS agencies, workers often do not seek treatment due to mental illness stigma. To facilitate treatment receipt and maintain a healthy workforce, we must understand factors contributing to stigma. Psychosocial safety climate refers to the degree to which workers perceive that their organization fosters a work environment focused on the protection of psychological health and safety. Despite its relevance, the relationship between PSC and mental illness stigma has yet to be examined. METHODS: Participants were recruited from EMS agencies in the Northeastern U.S. Census Region. We used an observational research design and multiple linear regression to investigate the relationship between overall levels of PSC using the Psychosocial Climate Scale (PSC-12) and mental illness stigma using the Endorsed and Anticipated Stigma Inventory - Workplace Stigma Subscale. We also examined separate facets of PSC to determine if one was more related to stigma. Using established guidelines and the Wilcoxon rank-sum test, we compared workers rating their agencies as having high-risk (≤37 points) or low-risk PSC levels (≥41 points). RESULTS: The sample was n = 124 EMS clinicians (Mage = 29.6, SDage = 9.2, 53.2% male). Most were White (88.7%) with some college/college degree (79.8%). After adjusting for age, gender, race, education, and mental health treatment receipt, clinicians reporting that their workplaces were less focused on psychosocial safety and health (i.e., lower overall levels of PSC) also reported elevated levels of stigma (b = -0.27, SE = 0.05, 95% CI = -0.37, -0.17, p < .001). Exploratory analyses indicated that no PSC facet was more related to stigma than another. Clinicians reporting high-risk levels displayed stigma levels that were 38% higher compared to clinicians reporting low-risk PSC levels. CONCLUSIONS: Psychosocial safety climate is an important and modifiable intervention target linked to mental illness stigma in EMS clinicians. Organizational policies, practices, and procedures that convey that mental health is valued and should be protected may reduce stigma and facilitate treatment receipt among this high-risk population.

Pain Appraisals in Patients with Physical Injury: Assessing the Role of Distress Tolerance in the Relationship between Depression and Pain Catastrophizing.

Pain is a complex construct contributing to significant impairment, particularly among physically injured patients seeking treatment in trauma and orthopedic surgery settings in which social workers are an integral component of care. The biopsychosocial theory, fear-avoidance, and cognitive mediation models of pain suggest that psychological factors (for example, depression) affect one's ability to tolerate distress, leading to negative pain appraisals, such as catastrophizing. This study examined whether distress tolerance serves as a mechanism by which depression is associated with pain catastrophizing. We administered a health survey to outpatient trauma and orthopedic surgery clinic patients who were using opioid medications; 84 patients were included in the final analysis; 39.3 percent screened positive for depression. A multilevel mediation model using structural equation modeling revealed a significant direct effect from depression to pain catastrophizing (ß = .31, z = 3.96, p < .001) and a significant indirect effect by distress tolerance (Δß = .27, z = 3.84, p < .001). These results, which suggest that distress tolerance partially mediated the path from depression to pain catastrophizing, can inform social workers and other members of the multidisciplinary team about both the critical role of psychosocial factors after injury and interventions to improve postinjury recovery.

Polytraumatization, Mental Health, and Delinquency Among Adolescent Gang Members.

Adolescent gang members are at high risk for polytraumatization (i.e., experiencing two or more types of trauma), which may contribute to behavioral problems, such as delinquency or drug distribution, and mental health symptoms, such as posttraumatic stress disorder (PTSD) and depression. The present study examined the associations between polytraumatization and these behavioral and mental health outcomes. We hypothesized that increased polytraumatization would lead to increased (b) mental health symptoms, (b) delinquency, and (c) drug distribution. Participants included 441 adolescent gang members (57.8% male; age range: 14-19 years) from a midsized city in the Midwestern United States. A path model was used to test hypotheses. A total of 88.0% of participants experienced polytraumatization, such as physical and sexual assault, involvement in accidents, or witnessing a death or injury. Polytraumatization was uniquely and positively associated with depressive and PTSD symptoms, delinquency, and drug distribution, ßs = .25-.50, ps < .001, explaining an additional 5.9%-22.5% of the variance in these outcomes beyond covariates. Untreated traumatic exposure among adolescent gang members may subsequently lead to poor behavioral and mental health outcomes. These results may inform prevention and intervention efforts focused on mental health and social justice among a high-risk adolescent population.

An evidence-based approach to emergency department patients at risk for posttraumatic stress disorder symptoms.

Approximately one-quarter of emergency department patients who are injured or experience medical emergencies will develop clinically significant posttraumatic stress disorder (PTSD) symptoms, which can evolve into PTSD. Emergency clinicians and rapid response teams (eg, trauma, cardiac, stroke) can play a critical role in recognizing symptoms of posttraumatic stress and providing early distress management techniques, screening, and referral to services that may mitigate the development of PTSD. This review summarizes the existing literature on psychological distress related to events that trigger the need for emergency care and synthesizes cutting-edge approaches that may impact patient outcomes.

Avoidance Coping as a Vulnerability Factor for Negative Drinking Consequences Among Injury Survivors Experiencing PTSD Symptoms:An Ecological Momentary Assessment Study.

The purpose of this study was to examine the dynamic relationships between daily PTSD symptom severity (PTSS), cognitive and behavioral avoidance coping, and negative drinking consequences following recent injury. Participants consisted of 36 injury survivors (Mage = 34.0, SD = 10.8; 75.0% male; 69.4% White) who completed thrice daily assessments of PTSS, avoidance coping, and negative drinking consequences for 7 days at 6-weeks post-injury. Although hypothesized relationships were not statistically significant in full models with covariates that included alcohol consumption, the confidence intervals associated with focal predictors provided support for predictions. Follow-up analyses without covariates indicated that on occasions when an injury survivor engaged in more avoidance coping and experienced higher levels of PTSS, negative drinking consequences increased by 9% (b = 0.02, SE = 0.01, p = .006). This interaction was primarily driven by cognitive avoidance coping (b = 0.03, SE = 0.01, p = .008). Routine screening of avoidance coping, PTSS, and alcohol consumption in the aftermath of recent injury might assist with identifying survivors at risk for negative drinking consequences. Interventions that address cognitive avoidance coping and drinking among survivors experiencing elevated PTSS may help to prevent the development of this comorbidity.

Examining the prevalence and health impairment associated with subthreshold PTSD symptoms (PTSS) among frontline healthcare workers during the COVID-19 pandemic.

The COVID-19 pandemic has increased healthcare workers' (HCWs) risk for posttraumatic stress disorder (PTSD). Although subthreshold PTSD symptoms (PTSS) are common and increase vulnerability for health impairments, they have received little attention. We examined the prevalence of subthreshold PTSS and their relationship to physical health symptoms and sleep problems among HCWs during the pandemic's second wave (01/21-02/21). Participants (N = 852; 63.1% male; Mage = 38.34) completed the Short-Form PTSD Checklist (SF-PCL), the Cohen-Hoberman Inventory of Physical Symptoms, and the PROMIS Sleep-Related Impairment-Short-Form 4a. We created three groups with the SF-PCL: scores ≥11 = probable PTSD (5.5%); scores between 1 and 10 = subthreshold PTSS (55.3%); scores of 0 = no PTSS (39.2%). After controlling for demographics, occupational characteristics, and COVID-19 status, HCWs with subthreshold PTSS experienced greater physical health symptoms and sleep problems than HCWs with no PTSS. While HCWs with PTSD reported the greatest health impairment, HCWs with subthreshold PTSS reported 88% more physical health symptoms and 36% more sleep problems than HCWs with no PTSS. Subthreshold PTSS are common and increase risk for health impairment. Interventions addressing HCWs' mental health in response to the COVID-19 pandemic must include subthreshold PTSS to ensure their effectiveness.

The mediating role of coping self-efficacy on social support and PTSD symptom severity among injury survivors.

BACKGROUND: Social support confers a protective effect against elevated PTSD symptomatology following injury. However, little is known about the mechanisms through which social support conveys this protective mental health effect in injury survivors. Coping self-efficacy is linked to both social support and PTSD symptomatology but has not been examined. OBJECTIVE: To test coping self-efficacy as a mechanism for the relationship between social support and PTSD symptom severity among injury survivors. METHOD AND DESIGN: Participants consisted of 61 injury survivors (62.3% male, 72.1% White) admitted to a Level-1 Trauma Center. Social support was assessed at 2-weeks post-injury; coping self-efficacy at 6-weeks post-injury; and PTSD symptom severity at 3-months post-injury. RESULTS: A statistically significant indirect effect was found for the social support - coping self-efficacy - PTSD symptomatology pathway, providing evidence of mediation even after controlling for age, sex, race, and education (B = -0.51, SE = 0.18, CI = -0.92, -0.20). CONCLUSIONS: Social support may exert an effect on PTSD symptom severity post-injury through its connection with coping self-efficacy. Coping self-efficacy represents an important intervention target following injury for those survivors with lower social support who are at risk for elevated PTSD symptom severity levels.

A longitudinal assessment of posttraumatic stress symptoms and pain catastrophizing after injury.

PURPOSE/OBJECTIVE: Identifying individuals with high levels of pain catastrophizing (PC) may inform early psychological interventions to prevent the transition from acute to chronic post-injury pain. We examined whether pre-and post-injury posttraumatic stress symptoms (PTSS) predict post-injury PC among emergency department (ED) patients following acute motor vehicle crash (MVC). RESEARCH METHOD/DESIGN: This study represents secondary data analysis of a randomized clinical trial (NCT03247179) examining the efficacy of the PTSD Coach app on post-injury PTSS (PTSSpost). Among 63 injured ED patients (63% female; 57% non-White; average age = 37) with moderate pain (≥4 of 10), we assessed recall of pre-injury PTSS (PTSSrecall: stemming from preexisting exposures) and baseline PC within 24 hr post-MVC; PTSSpost stemming from the MVC was assessed 30-days later, and the outcome of PC was assessed at 90-days post-injury. We controlled for group assignment (intervention vs. control) in all analyses. RESULTS: Results revealed that at baseline and 90-days, PC was higher among non-White versus White participants. After adjusting for relevant covariates, PTSSrecall uniquely predicted post-injury PC and each subscale of PC (helplessness, magnification, and rumination). Similarly, after controlling for PTSSrecall and relevant covariates, PTSSpost uniquely predicted total and subscale post-injury PC. Intervention group participants reported less rumination than control group participants. CONCLUSIONS/IMPLICATIONS: These novel findings highlight that injured Black patients may be vulnerable to post-injury PC, and that both PTSSrecall and PTSSpost significantly predict post-injury PC. Brief PTSS assessment in the ED can identify high-risk patients who may benefit from early intervention. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Association between trauma triage and time-to-vaso-occlusive events in patients with sickle cell disease after traumatic injury: a retrospective study.

Introduction: Sickle cell disease (SCD) is associated with vaso-occlusive events (VOEs) that can lead to disease complications, including early mortality. Given that similar inflammatory responses characterize VOE and traumatic injury, injured patients with SCD may be vulnerable to acute complications. This study is the first to examine whether traumatic injury is associated with increased severity of future VOEs. Methods: This cohort study was conducted using electronic health record data from an SCD clinic in Western Pennsylvania; 356 patients with SCD from January 2000 to July 2021 were identified via retrospective chart review. 55 patients were eligible based on continuous medical record data spanning 1 year preinjury and postinjury. Patients were sorted into three treatment groups based on injury management: (1) Neither triage to trauma team activation (TTA) nor inpatient admission (Early Discharge), (2) Triage but no inpatient admission (Triage Only), and (3) Triage and In-patient. Outcomes included time from injury to first VOE, annual VOE counts requiring an emergency department (ED) visit, and ED length of stay (LOS) for the first VOE after injury. Results: Early Discharge individuals experienced a VOE event within 2.93 days of injury, significantly shorter time to event than Triage and In-patient individuals at 52.375 days and Triage Only individuals at 100.16 days (p=0.0058). No difference in annual VOE counts was noted postinjury across all groups. However, a significant increase in VOE LOS preinjury (16.1 hours) to postinjury (77.4 hours) was noted only for the Triage Only group (p=0.038). Cox regression model showed that shortened time to VOE events was marginally associated with TTA status (p=0.06). Conclusion: Despite minimal changes in long-term VOE outcomes after injury, traumatic injuries may accelerate the time-to-VOE among the Early Discharge group. Therefore, future research is warranted to analyze whether the absence of postinjury triage assessment and intervention may cause unforeseen physiologic stressors contributing to VOE outcomes. Level of evidence: Level IV: retrospective case-control study with three negative criteria.

Incorporating community-level risk factors into traumatic stress research: Adopting a public health lens.

Infusing community-level risk factors into traumatic stress research can broaden intervention targets. The Neighborhood Deprivation Index (NDI) and the Index of Concentration at the Extremes (ICE) are two common community-level risk factors derived from U.S. census data. We provide R scripts facilitating the computation of these risk factors and demonstrate their relationship with PTSD symptomatology in 74 injury survivors assessed at 2-weeks, 6-weeks, and 3-months post-injury. The NDI and the ICE were computed using the Census Data Application Programming Interface, then matched to participants' census tracts using their residential addresses. Results indicated that after controlling for person-level characteristics, both risk factors were associated with PTSD symptom severity at follow up time points (Cohen's f2 =0.011,.14). This study provides an easy method for computing the NDI and ICE, demonstrates the increased mental health risk that they convey in the aftermath of injury, and highlights their value in intervention efforts.

Effectiveness of a Text Message Intervention to Reduce Texting While Driving Among Targeted Young Adults: A Randomized Controlled Trial.

PURPOSE: This randomized clinical trial tested the efficacy of a 6-week text message program to reduce texting while driving (TWD) for young adults. METHODS: Eligible individuals recruited from four emergency departments from December 2019 to June 2021 were aged 18-25 years who reported TWD in the past 2 weeks. Participants were randomly assigned 1:1 to intervention:assessment control. The intervention arm (n = 57) received an automated interactive text message program, including weekly queries about TWD for 6 weeks with feedback and goal support to promote cessation of TWD. The assessment control arm (n = 55) received identical weekly TWD queries but no additional feedback. Outcomes were collected via web-based self-assessments at 6- and 12 weeks and analyzed under intent-to-treat models, presented as adjusted odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: The mean (SD) age was 21.7 (2.1) years, 73 (65%) were female, and 40 (36%) were White. The 6-week follow-up rate was 77.7% (n = 87) and 12-week follow-up rate was 64.3% (n = 72). At 6 weeks, 52.6% (95% CI, 39.0%-66.0%) of intervention participants reported TWD versus 63.6% (95% CI, 49.6%-76.2%) of control participants (adjusted OR, 0.71; 95% CI, 0.32-1.59). At 12 weeks, 38.2% (95% CI, 22.8%-53.5%) of intervention participants reported TWD versus 69.3% (95% CI, 53.8%-84.7%) of control participants (adjusted OR, 0.29; 95% CI, 0.11-0.80). DISCUSSION: An interactive text message intervention was more effective at reducing self-reported TWD among young adults than assessment control at 12 weeks.

Effectiveness of a Text Message Intervention Promoting Seat Belt Use Among Young Adults: A Randomized Clinical Trial.

Importance: Approximately 1 in 10 adults do not always wear a seat belt, with the lowest use rates reported among young adults. Objective: To determine the efficacy of a 6-week automated behavioral text message program promoting seat belt use compared with an attention control. Design, Setting, and Participants: This parallel, 2-group, single-blind, individually randomized clinical trial included a convenience sample of patients recruited from 4 emergency departments in 2 cities in Pennsylvania from December 2019 to September 2021, with follow-ups at 6 and 12 weeks after randomization. Patients in stable condition aged 18 to 25 years who, in standardized screening, reported driving or being a passenger in a car without always using a seat belt in the past 2 weeks were eligible for recruitment. Participants who completed a 2-week trial run-in phase were randomly assigned 1:1 to the intervention or the assessment control. Data were analyzed from October 2019 to January 2020. Interventions: The intervention group received Safe Vehicle Engagement (SAVE), a 6-week automated interactive text message program, including weekly seat belt use queries with feedback and goal support to promote consistent use of a seat belt. The control group received identical weekly seat belt use queries but no additional feedback. Main Outcomes and Measures: The primary outcome was the proportion of young adults reporting always wearing a seat belt over the past 2 weeks, collected at 6 weeks (after a 2-week run-in) via web-based self-assessments and analyzed under intent-to-treat models using multiple imputation procedures. Sensitivity analyses included complete-case analyses of ordered categorical outcomes by vehicle seat position. Secondary outcomes included seatbelt use at 12 weeks and select cognitive constructs related to seat belt use. Results: A total of 218 participants (mean [SD] age, 21.5 [2.1] years; 139 [63.8%] women) were randomized, with 110 randomized to SAVE and 108 randomized to the control group. A total of 158 individuals (72.4%) were included in the 6-week follow-up. The rate of always using a seat belt over the past 2 weeks at the 6-week follow-up was 41.3% (95% CI, 30.6%-52.0%) among SAVE participants and 20.0% (95% CI, 10.6%-29.3%) among control participants (odds ratio [OR], 2.8; 95% CI, 1.4-5.8; P = .005). A total of 140 individuals (64.2%) participated in the 12-week follow-up. At 12 weeks, the rate of always using a seat belt over the past 2-weeks was 42.8% (95% CI, 31.2%-54.2%) among SAVE participants and 30.7% (95% CI, 19.6%-41.6%) among control participants (OR, 1.7; 95% CI, 0.9-3.4; P = .13). When examining ordered categories of seat belt use by seat position, there were significantly greater odds of wearing a seat belt at 6 and 12 weeks among SAVE participants vs control participants (eg, 6 weeks for driver: OR, 5.2; 95% CI, 2.6-10.5; 6 weeks for front passenger: OR, 4.3; 95% CI, 2.2-8.2; 6 weeks for back passenger: OR, 4.3; 95% CI, 2.2-8.2). Conclusions and Relevance: In this randomized clinical trial, an interactive text message intervention was more effective at promoting seat belt use among targeted young adults than an attention control at 6 weeks. There was no significant difference between groups in always wearing a seat belt at 12 weeks. These findings, if replicated in a larger sample, suggest a scalable approach to improve seat belt use.

Distress tolerance among emergency department patients in acute pain: Associations with substance use treatment.

Managing acute pain in individuals with a history of substance use disorders (SUD) is complex. Distress tolerance (DT) (e.g., the ability to handle uncomfortable sensations) may serve as an ideal non-pharmacological intervention target in this population. Among 293 emergency department (ED) patients seeking treatment for pain (Mage  = 41; 42% Female; 43% Black), we examined rates of SUD treatment and DT, whether an objective DT task is feasible to conduct in the ED, and relationships between DT and SUD. Patients completed a self-report DT survey, an objective DT task, and brief surveys of pain, drug use, current or past SUD treatment, and depression/anxiety. Average DT was 18.50 (SD = 9.4) out of 50; patients with past or current SUD treatment (n = 43; 14.7%) reported lower DT than patients with no SUD treatment history (n = 250; 85.3%). Controlling for demographics, depression/anxiety, and pain severity, lower subjective DT (adjusted odds ratio [aOR] = 1.05) and objective DT (aOR = 1.02) was associated a current or past history or SUD treatment. Assessing subjective and objective DT in ED patients with acute pain is feasible; interventions aimed at boosting DT may improve outcomes among patients with acute pain and SUD.

The role of specific sources of social support on postinjury psychological symptoms.

PURPOSE/OBJECTIVE: The role of perceived social support from specific sources (e.g., families, friends, and significant others) on the development of postinjury posttraumatic stress disorder (PTSD) and associated psychological symptoms (e.g., depression and anxiety) remains relatively unexplored. We examined the predictive role of social support from specific sources on psychological symptoms among emergency department (ED) patients following motor vehicle crash (MVC). Research Methods/Design: Sixty-three injured patients (63.5% female; 37 years old on average) with moderately painful complaints were recruited in the EDs of two Level-1 trauma centers within 24 hr post-MVC. In the ED, participants completed surveys of baseline psychological symptoms and perceived social support; follow-up surveys were completed at 90 days postinjury. RESULTS: Most of the sample (84.1%) was discharged home from the ED with predominantly mild injuries and did not require hospitalization. After adjusting for race, sex, age, and baseline symptoms, hierarchical regression analyses demonstrated that lower perceived social support in the ED predicted higher PTSD symptoms and depressive symptoms (but not anxiety) at 90 days. This effect seemed to be specific to significant others and friends but not family. CONCLUSIONS/IMPLICATIONS: MVC-related injuries are robust contributors to psychological sequelae. These findings extend prior work by highlighting that perceived social support, particularly from significant others and friends, provides unique information regarding the development of psychological symptoms following predominantly mild MVC-related injuries. This data may serve to inform recovery expectations. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

COVID-19 Vaccine Uptake and Intent Among Emergency Healthcare Workers: A Cross-Sectional Survey.

OBJECTIVE: Vaccine hesitancy limits population protection from SARS-CoV (coronavirus disease [COVID-19]). Vaccine hesitancy among healthcare workers (HCW) could put patients and coworkers at risk. METHODS: We surveyed 475 emergency department and emergency medical service workers from January to February 2021 to determine vaccine intent/uptake, perceived COVID-19 vulnerability, and factors associated with vaccine intent/uptake. RESULTS: Although 79% of HCWs received or had plans to receive the COVID-19 vaccine, 21% had no intent/were unvaccinated; intent/uptake was lower among females (odds ratio [OR] = 0.34) and those with a history of COVID-19 infection (OR = 0.55), and higher among those with advanced degrees (OR = 3.53) and high perceived COVID-19 vulnerability (OR = 1.99). CONCLUSIONS: This study provides a timely assessment of vaccination status among frontline HCWs and highlights subgroups who may be at high risk of exposure and transmission.

Event centrality following treatment for physical injury in the emergency department: Associations with posttraumatic outcomes.

BACKGROUND: The relationship between event centrality (i.e., the degree to which a stressful event is integrated into one's identity) and acute posttraumatic outcomes after relatively minor physical injury is unknown. We examined pre-injury and Emergency Department (ED) predictors of event centrality at 6-weeks post-injury, and whether event centrality is uniquely associated with 6-week posttraumatic outcomes. METHODS: In the EDs of two Level I trauma centers, 149 patients completed surveys regarding demographic, psychological and injury-related factors within 24 h post-injury; 84 patients (51% male) completed 6-week surveys of event centrality, posttraumatic stress symptoms (PTSS) and trauma-specific QOL (T-QoL). Data were analyzed using linear regression modeling. RESULTS: At least 20% of patients agreed or strongly agreed that the injury changed their life. Hospitalization status and peritraumatic dissociation were significant predictors of event centrality at 6-weeks. After controlling for demographics, ED-related factors and pre-injury PTSS, event centrality was uniquely associated with PTSS (p < .001) and T-QOL (p < .001) at 6 weeks. CONCLUSION: Over and above the effects of the injury itself, event centrality conveyed important information for posttraumatic outcomes at 6 weeks post-injury. The centrality scale is brief and feasible to administer; future work is needed to determine the predictive utility of event centrality on post-injury outcomes.

A Pilot Randomized Controlled Trial of the PTSD Coach App Following Motor Vehicle Crash-related Injury.

OBJECTIVE: Posttraumatic stress disorder (PTSD) symptoms (PTSS) are common after minor injuries and can impair recovery. We sought to understand whether an evidence-based mobile phone application with self-help tools (PTSD Coach) could be useful to improve recovery after acute trauma among injured emergency department (ED) patients. This pilot study examined the feasibility, acceptability, and potential benefit of using PTSD Coach among acutely injured motor vehicle crash (MVC) patients. METHODS: From September 2017 to September 2018, we recruited adult patients within 24 hours post-MVC from the EDs of two Level I trauma centers in the United States. We randomly assigned 64 injured adults to either the PTSD Coach (n = 33) or treatment as usual (TAU; n = 31) condition. We assessed PTSS and associated symptoms at 1 month (83% retained) and 3 months (73% retained) postenrollment. RESULTS: Enrollment was feasible (74% of eligible subjects participated) but usability and engagement were low (67% used PTSD Coach at least once, primarily in week 1); 76% of those who used it rated the app as moderately to extremely helpful. No differences emerged between groups in PTSS outcomes. Exploratory analyses among black subjects (n = 21) indicated that those in the PTSD Coach condition (vs. TAU) reported marginally lower PTSS (95% CI = -0.30 to 37.77) and higher PTSS coping self-efficacy (95% CI = -58.20 to -3.61) at 3 months. CONCLUSIONS: We demonstrated feasibility to recruit acutely injured ED patients into an app-based intervention study, yet mixed evidence emerged for the usability and benefit of PTSD Coach. Most patients used the app once and rated it favorably in regard to satisfaction with and helpfulness, but longitudinal engagement was low. This latter finding may explain the lack of overall effects on PTSS. Additional research is warranted regarding whether targeting more symptomatic patients and the addition of engagement and support features can improve efficacy.

Cardiac arrest survivors lost to follow-up after 3-Months, 6-Months and 1-Year.

BACKGROUND: Long-term assessment of global functional outcomes in cardiac arrest (CA) survivors allows for evaluation of acute care practices and referral to rehabilitation services. Given that many post-CA patients are lost to follow-up (LTFU), we explored whether these patients are systematically different from those who complete follow-up based on demographic, resuscitation and outcome characteristics. METHODS: We conducted a prospective cohort study of 168 English-speaking CA survivors between 9/25/2016 and 5/31/2018. We measured demographic data and global functional outcomes using Modified Rankin Scale (mRS), and Cerebral Performance Category (CPC) in-person at hospital discharge, and via telephone at 3-, 6-months, and 1-year. We compared patients LTFU (e.g., failure to contact or refused to follow-up) with those contacted. Patients who were hospitalized, in a rehabilitation facility, missed by the research team, or dead were considered not eligible for follow-up. RESULTS: Of the 116 patients eligible for follow-up at 3-months, the majority completed follow-up (n = 69; 59.5%) and 47 (40.5%) were LTFU. Conversely, at 6-months and 1-year, fewer subjects were assessed (42% and 47%) compared to those who were LTFU (58% and 53%), respectively. At 3-months, LTFU patients were younger, unmarried, and had longer ICU stay. At 6-months and 1-year, LTFU patients were primarily male, had a non-shockable primary rhythm, and non-cardiac arrest etiologies. CONCLUSIONS: Over one-third of patients are LTFU during the first year after CA, and differences emerged for demographics and characteristics of the event. Future research should account for the informative, non-random distribution of patients LTFU.
