Associations of alcohol and cannabis use with change in posttraumatic stress disorder and depression symptoms over time in recently trauma-exposed individuals.

BACKGROUND: Several hypotheses may explain the association between substance use, posttraumatic stress disorder (PTSD), and depression. However, few studies have utilized a large multisite dataset to understand this complex relationship. Our study assessed the relationship between alcohol and cannabis use trajectories and PTSD and depression symptoms across 3 months in recently trauma-exposed civilians. METHODS: In total, 1618 (1037 female) participants provided self-report data on past 30-day alcohol and cannabis use and PTSD and depression symptoms during their emergency department (baseline) visit. We reassessed participant's substance use and clinical symptoms 2, 8, and 12 weeks posttrauma. Latent class mixture modeling determined alcohol and cannabis use trajectories in the sample. Changes in PTSD and depression symptoms were assessed across alcohol and cannabis use trajectories via a mixed-model repeated-measures analysis of variance. RESULTS: Three trajectory classes (low, high, increasing use) provided the best model fit for alcohol and cannabis use. The low alcohol use class exhibited lower PTSD symptoms at baseline than the high use class; the low cannabis use class exhibited lower PTSD and depression symptoms at baseline than the high and increasing use classes; these symptoms greatly increased at week 8 and declined at week 12. Participants who already use alcohol and cannabis exhibited greater PTSD and depression symptoms at baseline that increased at week 8 with a decrease in symptoms at week 12. CONCLUSIONS: Our findings suggest that alcohol and cannabis use trajectories are associated with the intensity of posttrauma psychopathology. These findings could potentially inform the timing of therapeutic strategies.

Sex-dependent differences in vulnerability to early risk factors for posttraumatic stress disorder: results from the AURORA study.

BACKGROUND: Knowledge of sex differences in risk factors for posttraumatic stress disorder (PTSD) can contribute to the development of refined preventive interventions. Therefore, the aim of this study was to examine if women and men differ in their vulnerability to risk factors for PTSD. METHODS: As part of the longitudinal AURORA study, 2924 patients seeking emergency department (ED) treatment in the acute aftermath of trauma provided self-report assessments of pre- peri- and post-traumatic risk factors, as well as 3-month PTSD severity. We systematically examined sex-dependent effects of 16 risk factors that have previously been hypothesized to show different associations with PTSD severity in women and men. RESULTS: Women reported higher PTSD severity at 3-months post-trauma. Z-score comparisons indicated that for five of the 16 examined risk factors the association with 3-month PTSD severity was stronger in men than in women. In multivariable models, interaction effects with sex were observed for pre-traumatic anxiety symptoms, and acute dissociative symptoms; both showed stronger associations with PTSD in men than in women. Subgroup analyses suggested trauma type-conditional effects. CONCLUSIONS: Our findings indicate mechanisms to which men might be particularly vulnerable, demonstrating that known PTSD risk factors might behave differently in women and men. Analyses did not identify any risk factors to which women were more vulnerable than men, pointing toward further mechanisms to explain women's higher PTSD risk. Our study illustrates the need for a more systematic examination of sex differences in contributors to PTSD severity after trauma, which may inform refined preventive interventions.

Structural inequities contribute to racial/ethnic differences in neurophysiological tone, but not threat reactivity, after trauma exposure.

Considerable racial/ethnic disparities persist in exposure to life stressors and socioeconomic resources that can directly affect threat neurocircuitry, particularly the amygdala, that partially mediates susceptibility to adverse posttraumatic outcomes. Limited work to date, however, has investigated potential racial/ethnic variability in amygdala reactivity or connectivity that may in turn be related to outcomes such as post-traumatic stress disorder (PTSD). Participants from the AURORA study (n = 283), a multisite longitudinal study of trauma outcomes, completed functional magnetic resonance imaging and psychophysiology within approximately two-weeks of trauma exposure. Seed-based amygdala connectivity and amygdala reactivity during passive viewing of fearful and neutral faces were assessed during fMRI. Physiological activity was assessed during Pavlovian threat conditioning. Participants also reported the severity of posttraumatic symptoms 3 and 6 months after trauma. Black individuals showed lower baseline skin conductance levels and startle compared to White individuals, but no differences were observed in physiological reactions to threat. Further, Hispanic and Black participants showed greater amygdala connectivity to regions including the dorsolateral prefrontal cortex (PFC), dorsal anterior cingulate cortex, insula, and cerebellum compared to White participants. No differences were observed in amygdala reactivity to threat. Amygdala connectivity was associated with 3-month PTSD symptoms, but the associations differed by racial/ethnic group and were partly driven by group differences in structural inequities. The present findings suggest variability in tonic neurophysiological arousal in the early aftermath of trauma between racial/ethnic groups, driven by structural inequality, impacts neural processes that mediate susceptibility to later PTSD symptoms.

Internal capsule microstructure mediates the relationship between childhood maltreatment and PTSD following adulthood trauma exposure.

Childhood trauma is a known risk factor for trauma and stress-related disorders in adulthood. However, limited research has investigated the impact of childhood trauma on brain structure linked to later posttraumatic dysfunction. We investigated the effect of childhood trauma on white matter microstructure after recent trauma and its relationship with future posttraumatic dysfunction among trauma-exposed adult participants (n = 202) recruited from emergency departments as part of the AURORA Study. Participants completed self-report scales assessing prior childhood maltreatment within 2-weeks in addition to assessments of PTSD, depression, anxiety, and dissociation symptoms within 6-months of their traumatic event. Fractional anisotropy (FA) obtained from diffusion tensor imaging (DTI) collected at 2-weeks and 6-months was used to index white matter microstructure. Childhood maltreatment load predicted 6-month PTSD symptoms (b = 1.75, SE = 0.78, 95% CI = [0.20, 3.29]) and inversely varied with FA in the bilateral internal capsule (IC) at 2-weeks (p = 0.0294, FDR corrected) and 6-months (p = 0.0238, FDR corrected). We observed a significant indirect effect of childhood maltreatment load on 6-month PTSD symptoms through 2-week IC microstructure (b = 0.37, Boot SE = 0.18, 95% CI = [0.05, 0.76]) that fully mediated the effect of childhood maltreatment load on PCL-5 scores (b = 1.37, SE = 0.79, 95% CI = [-0.18, 2.93]). IC microstructure did not mediate relationships between childhood maltreatment and depressive, anxiety, or dissociative symptomatology. Our findings suggest a unique role for IC microstructure as a stable neural pathway between childhood trauma and future PTSD symptoms following recent trauma. Notably, our work did not support roles of white matter tracts previously found to vary with PTSD symptoms and childhood trauma exposure, including the cingulum bundle, uncinate fasciculus, and corpus callosum. Given the IC contains sensory fibers linked to perception and motor control, childhood maltreatment might impact the neural circuits that relay and process threat-related inputs and responses to trauma.

Derivation and Validation of a Brief Emergency Department-Based Prediction Tool for Posttraumatic Stress After Motor Vehicle Collision.

STUDY OBJECTIVE: To derive and initially validate a brief bedside clinical decision support tool that identifies emergency department (ED) patients at high risk of substantial, persistent posttraumatic stress symptoms after a motor vehicle collision. METHODS: Derivation (n=1,282, 19 ED sites) and validation (n=282, 11 separate ED sites) data were obtained from adults prospectively enrolled in the Advancing Understanding of RecOvery afteR traumA study who were discharged from the ED after motor vehicle collision-related trauma. The primary outcome was substantial posttraumatic stress symptoms at 3 months (Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders-5 ≥38). Logistic regression derivation models were evaluated for discriminative ability using the area under the curve and the accuracy of predicted risk probabilities (Brier score). Candidate posttraumatic stress predictors assessed in these models (n=265) spanned a range of sociodemographic, baseline health, peritraumatic, and mechanistic domains. The final model selection was based on performance and ease of administration. RESULTS: Significant 3-month posttraumatic stress symptoms were common in the derivation (27%) and validation (26%) cohort. The area under the curve and Brier score of the final 8-question tool were 0.82 and 0.14 in the derivation cohort and 0.76 and 0.17 in the validation cohort. CONCLUSION: This simple 8-question tool demonstrates promise to risk-stratify individuals with substantial posttraumatic stress symptoms who are discharged to home after a motor vehicle collision. Both external validation of this instrument, and work to further develop more accurate tools, are needed. Such tools might benefit public health by enabling the conduct of preventive intervention trials and assisting the growing number of EDs that provide services to trauma survivors aimed at promoting psychological recovery.

Perspectives on Telehealth for older adults during the COVID-19 pandemic using the quadruple aim: interviews with 48 physicians.

BACKGROUND: Telehealth delivery expanded quickly during the COVID-19 pandemic after the reduction of payment and regulatory barriers, but older adults are the least likely to benefit from this expansion. Little is known about physician experiences initiating telehealth and factors that fostered or discouraged adoption during the COVID-19 pandemic with older adult patients. Therefore, our objective was to understand experiences of frontline physicians caring for older adults via telehealth during the COVID-19 pandemic. METHODS: We conducted semi-structured interviews from September 2020 to November 2020 with 48 physicians. We recruited a diverse sample of geriatricians (n = 18), primary care (n = 15), and emergency (n = 15) physicians from all United Stated (US) regions, rural-urban settings, and academic-community practices who cared for older adult patients during the pandemic using purposive sampling methods. We completed framework analysis of the transcribed interviews to identify emerging themes and used the Quadruple Aim to organize themes. RESULTS: Frontline physicians described telehealth as a more flexible, value-based, and patient-centered mode of health care delivery. Benefits of using telehealth to treat older adults included reducing deferred care and increasing timely care, improving efficiency for physicians, enhancing communication with caregivers and patients, reducing patient travel burdens, and facilitating health outreach and education. Challenges included unequal access for rural, older, or cognitively impaired patients. Physicians noted that payment parity with in-person visits, between video and telephone visits, and relaxation of restrictive regulations would enhance their ability to continue to offer telehealth. CONCLUSIONS: Frontline physicians who treated older adults during the COVID-19 pandemic were largely in favor of continuing telehealth use beyond the pandemic; however, they noted that sustainability would depend on enacting policies that address access inequities and reimbursement concerns. Our data provide policy insights that if placed into action could facilitate the long-term success of telehealth and encourage a more flexible healthcare delivery system in the US.

A systematic review of HIV screening programs conducted in pediatric emergency departments in the United States.

BACKGROUND: We conducted a systematic review of studies published in peer-reviewed journals on HIV screening programs conducted in pediatric emergency departments (PEDs) in the United States (US) with the objective of describing the methods, testing yields and challenges in these programs. METHODS: We searched for full-text, English-language, original research articles focused on the conduct, development, initiation or implementation of any HIV screening program in a US PED through eight online databases (Pubmed (MEDLINE), Scopus, Embase, Cochrane, Web of Science, CINAHL, PsycInfo and Google Scholar) from their inception through July 2020. We also searched for articles on the websites of thirteen emergency medicine journals, 24 pediatric and adolescent health journals, and ten HIV research journals, and using the references of articles found through these searches. Data on HIV testing program components and yield of testing was extracted by one investigator independently and verified by a second investigator. Each program was summarized and critiqued. RESULTS: Of the eight articles that met inclusion criteria, most involved descriptions of their HIV testing program, except for one that was focused on quality improvement of their program. Five described an opt-in and three an opt-out approach to HIV screening. Programs differed greatly by type of HIV test utilized and who initiated or performed testing. There were large variations in the percentage of patients offered (4.0% to 96.7%) and accepting (42.7% to 86.7%) HIV testing, and HIV seropositivity in the studies ranged from 0 to 0.6%. Five of the eight studies reported an HIV seropositivity greater than 0.1%, above Centers for Disease Control and Prevention recommended threshold for testing in a healthcare setting. CONCLUSIONS: The studies illustrate opportunities to further optimize the integration of HIV screening programs within US PEDs and reduce barriers to testing, improve efficiency of testing results and increase effectiveness of programs to identify cases. Future research should focus on advancing the methodology of screening programs beyond feasibility studies as well as conducting investigations on their implementation and longer-term sustainability.

Respiratory Variation in Carotid Artery Peak Systolic Velocity Is Unable to Predict Fluid Responsiveness in Spontaneously Breathing Critically Ill Patients When Assessed by Novice Physician Sonologists.

BACKGROUND: Respiratory variation in carotid artery peak systolic velocity (ΔVpeak) assessed by point-of-care ultrasound (POCUS) has been proposed as a noninvasive means to predict fluid responsiveness. We aimed to evaluate the ability of carotid ΔVpeak as assessed by novice physician sonologists to predict fluid responsiveness. METHODS: This study was conducted in 2 intensive care units. Spontaneously breathing, nonintubated patients with signs of volume depletion were included. Patients with atrial fibrillation/flutter, cardiogenic, obstructive or neurogenic shock, or those for whom further intravenous (IV) fluid administration would be harmful were excluded. Three novice physician sonologists were trained in POCUS assessment of carotid ΔVpeak. They assessed the carotid ΔVpeak in study participants prior to the administration of a 500 mL IV fluid bolus. Fluid responsiveness was defined as a ≥10% increase in cardiac index as measured using bioreactance. RESULTS: Eighty-six participants were enrolled, 50 (58.1%) were fluid responders. Carotid ΔVpeak performed poorly at predicting fluid responsiveness. Test characteristics for the optimum carotid ΔVpeak of 8.0% were: area under the receiver operating curve = 0.61 (95% CI: 0.48-0.73), sensitivity = 72.0% (95% CI: 58.3-82.56), specificity = 50.0% (95% CI: 34.5-65.5). CONCLUSIONS: Novice physician sonologists using POCUS are unable to predict fluid responsiveness using carotid ΔVpeak. Until further research identifies key limiting factors, clinicians should use caution directing IV fluid resuscitation using carotid ΔVpeak.

Opioid Analgesics and Persistent Pain After an Acute Pain Emergency Department Visit: Evidence from a Cohort of Suspected Urolithiasis Patients.

BACKGROUND: Severe acute pain is still commonly treated with opioid analgesics in the United States, but this practice could prolong the duration of pain. OBJECTIVES: Estimate the risk of experiencing persistent pain after opioid analgesic use after emergency department (ED) discharge among patients with suspected urolithiasis. METHODS: We analyzed data collected for a longitudinal, multicenter clinical trial of ED patients with suspected urolithiasis. We constructed multilevel models to estimate the odds ratios (ORs) of reporting pain at 3, 7, 30, or 90 days after ED discharge, using multiple imputation to account for missing outcome data. We controlled for clinical, demographic, and institutional factors and used weighting to account for the propensity to be prescribed an opioid analgesic at ED discharge. RESULTS: Among 2413 adult ED patients with suspected urolithiasis, 62% reported persistent pain 3 days after discharge. Participants prescribed an opioid analgesic at discharge were OR 2.51 (95% confidence interval [CI] 1.82-3.46) more likely to report persistent pain than those without a prescription. Those who reported using opioid analgesics 3 days after discharge were OR 2.24 (95% CI 1.77-2.84) more likely to report pain at day 7 than those not using opioid analgesics at day 3, and those using opioid analgesics at day 30 had OR 3.25 (95% CI 1.96-5.40) greater odds of pain at day 90. CONCLUSIONS: Opioid analgesic prescription doubled the odds of persistent pain among ED patients with suspected urolithiasis. Limiting opioid analgesic prescribing at ED discharge for these patients might prevent persistent pain in addition to limiting access to these medications.

Delay in Antibiotic Administration Is Associated With Mortality Among Septic Shock Patients With Staphylococcus aureus Bacteremia.

OBJECTIVES: The relationship between the timing of antibiotics and mortality among septic shock patients has not been examined among patients specifically with Staphylococcus aureus bacteremia. DESIGN: Retrospective analysis of a Veterans Affairs S. aureus bacteremia database. SETTING: One-hundred twenty-two hospitals in the Veterans Affairs Health System. PATIENTS: Patients with septic shock and S. aureus bacteremia admitted directly from the emergency department to the ICU from January 1, 2003, to October 1, 2015, were evaluated. INTERVENTIONS: Time to appropriate antibiotic administration and 30-day mortality. MEASUREMENTS AND MAIN RESULTS: A total of 506 patients with S. aureus bacteremia and septic shock were included in the analysis. Thirty-day mortality was 78.1% for the entire cohort and was similar for those participants with methicillin-resistant S. aureus and methicillin-sensitive S. aureus bacteremia. Our multivariate analysis revealed that, as compared with those who received appropriate antibiotics within 1 hour after emergency department presentation, each additional hour that passed before appropriate antibiotics were administered produced an odds ratio of 1.11 (95% CI, 1.02-1.21) of mortality within 30 days. This odds increase equates to an average adjusted mortality increase of 1.3% (95% CI, 0.4-2.2%) for every hour that passes before antibiotics are administered. CONCLUSIONS: The results of this study further support the importance of prompt appropriate antibiotic administration for patients with septic shock. Physicians should consider acting quickly to administer antibiotics with S. aureus coverage to any patient suspected of having septic shock.

Can an Emergency Department-Initiated Intervention Prevent Subsequent Falls and Health Care Use in Older Adults? A Randomized Controlled Trial.

STUDY OBJECTIVE: We determine whether an emergency department (ED)-initiated fall-prevention intervention can reduce subsequent fall-related and all-cause ED visits and hospitalizations in older adults. METHODS: The Geriatric Acute and Post-acute Fall Prevention intervention was a randomized controlled trial conducted from January 2018 to October 2019. Participants at 2 urban academic EDs were randomly assigned (1:1) to an intervention or usual care arm. Intervention participants received a brief, tailored, structured, pharmacy and physical therapy consultation in the ED, with automated communication of the recommendations to their primary care physicians. RESULTS: Of 284 study-eligible participants, 110 noninstitutionalized older adults (≥65 years) with a recent fall consented to participate; median age was 81 years, 67% were women, 94% were white, and 16.3% had cognitive impairment. Compared with usual care participants (n=55), intervention participants (n=55) were half as likely to experience a subsequent ED visit (adjusted incidence rate ratio 0.47 [95% CI 0.29 to 0.74]) and one third as likely to have fall-related ED visits (adjusted incidence rate ratio 0.34 [95% CI 0.15 to 0.76]) within 6 months. Intervention participants experienced half the rate of all hospitalizations (adjusted incidence rate ratio 0.57 [95% CI 0.31 to 1.04]), but confidence intervals were wide. There was no difference in fall-related hospitalizations between groups (adjusted incidence rate ratio 0.99 [95% CI 0.31 to 3.27]). Self-reported adherence to pharmacy and physical therapy recommendations was moderate; 73% of pharmacy recommendations were adhered to and 68% of physical therapy recommendations were followed. CONCLUSION: Geriatric Acute and Post-acute Fall Prevention, a postfall, in-ED, multidisciplinary intervention with pharmacists and physical therapists, reduced 6-month ED encounters in 2 urban EDs. The intervention could provide a model of care to other health care systems aiming to reduce costly and burdensome fall-related events in older adults.

Limited Ability of Three Health Literacy Screening Items to Identify Adult English- and Spanish-Speaking Emergency Department Patients With Lower Health Literacy.

STUDY OBJECTIVE: Brief, easily administered, and valid health literacy assessment tools are needed to optimize health care delivery in the emergency medicine setting. Three health literacy screening items have been proposed to assess health literacy in outpatient settings. We investigated their ability to identify English- and Spanish-speaking adult emergency department (ED) patients with lower health literacy. METHODS: Participants were Spanish- or English-speaking adult patients randomly selected from 4 geographically spread, US, urban, safety-net EDs. Participants completed the 3 health literacy screening items, as well as the Short Assessment of Health Literacy-Spanish and English (SAHL-S&E). Test performance characteristics, including receiver operating characteristics area under the curve, of the 3 health literacy screening items were estimated, as compared with the SAHL-S&E. RESULTS: According to the SAHL-S&E, 36% of the 1,165 English speakers and 35% of the 1,605 Spanish speakers had lower health literacy. Areas under the curve for each health literacy screening item individually were: needing others to help read materials (English 0.59, 95% confidence interval [CI] 0.56 to 0.62; Spanish 0.58, 95% CI 0.56 to 0.61), problems learning because of difficulty reading (English 0.63, 95% CI 0.60 to 0.66; Spanish 0.59, 95% CI 0.56 to 0.62), and confidence with completing forms (English 0.62, 95% CI 0.59 to 0.65; Spanish 0.60, 95% CI 0.57 to 0.63). Areas under the curve for the 3 screening items combined were: English 0.66 (95% CI 0.63 to 0.70) and Spanish 0.62 (95% CI 0.59 to 0.64). CONCLUSION: The 3 health literacy screening items performed poorly in identifying adult ED patients with lower health literacy. Higher-validity screening measures are needed to better serve the health care needs of this vulnerable population in the ED setting.

Performance of a 25% Inferior Vena Cava Collapsibility in Detecting Fluid Responsiveness When Assessed by Novice Versus Expert Physician Sonologists.

OBJECTIVES: Inferior vena cava collapsibility (cIVC) measured by point-of-care ultrasound (POCUS) has been proposed as a noninvasive means of assessing fluid responsiveness. We aimed to prospectively evaluate the performance of a 25% cIVC cutoff value to detect fluid responsiveness among spontaneously breathing intensive care unit (ICU) patients when assessed with POCUS by novice versus expert physician sonologists. METHODS: Prospective observational study of spontaneously breathing ICU patients. Fluid responsiveness was defined as a >10% increase in cardiac index following a 500 mL fluid bolus, measured by bioreactance. Novice sonologist measured cIVC with POCUS. Their measurements were later compared to an expert physician sonologist who independently reviewed the POCUS images and assessed cIVCs. RESULTS: Of the 85 participants, 44 (52%) were fluid responders. A 25% cIVC cutoff value performed better when assessed by expert sonologists than novice physician sonologists (receiver-operator characteristic curve, ROC = 0.82 [0.74-0.88] vs ROC = 0.69 [0.60-0.77]). CONCLUSIONS: A 25% cIVC cutoff value measured by POCUS detects fluid responsiveness. However, the experience of the physician sonologist affects test performance and should be considered when interpreting and clinically using cIVC to direct intravenous fluid resuscitation.

Variation in opioid analgesia administration and discharge prescribing for emergency department patients with suspected urolithiasis.

OBJECTIVE: Previous research has suggested caution about opioid analgesic usage in the emergency department (ED) setting and raised concerns about variations in prescription opioid analgesic usage, both across institutions and for whom they are prescribed. We examined opioid analgesic usage in ED patients with suspected urolithiasis across fifteen participating hospitals. METHODS: This is a secondary analysis of a clinical trial including adult ED patients with suspected urolithiasis. In multilevel models accounting for clustering by hospital, we assessed demographic, clinical, state-level, and hospital-level factors associated with opioid analgesic administration during the ED visit and prescription at discharge. RESULTS: Of 2352 participants, 67% received an opioid analgesic during the ED visit and 61% were prescribed one at discharge. Opioid analgesic usage varied greatly across hospitals, ranging from 46% to 88% (during visit) and 34% to 85% (at discharge). Hispanic patients were less likely than non-Hispanic white patients to receive opioid analgesics during the ED visit (OR 0.72, 95% CI 0.55-0.94). Patients with higher education (OR 1.29, 95% CI 1.05-1.59), health insurance coverage (OR 1.27, 95% CI 1.02-1.60), or receiving care in states with a prescription drug monitoring program (OR 1.64, 95% CI 1.06-2.53) were more likely to receive an opioid analgesic prescription at ED discharge. CONCLUSION: We found marked hospital-level differences in opioid analgesic administration and prescribing, as well as associations with education, healthcare insurance, and race/ethnicity groups. These data might compel clinicians and hospitals to examine their opioid use practices to ensure it is congruent with accepted medical practice.

The Restrictive IV Fluid Trial in Severe Sepsis and Septic Shock (RIFTS): A Randomized Pilot Study.

OBJECTIVES: It is unclear if a low- or high-volume IV fluid resuscitation strategy is better for patients with severe sepsis and septic shock. DESIGN: Prospective randomized controlled trial. SETTING: Two adult acute care hospitals within a single academic system. PATIENTS: Patients with severe sepsis and septic shock admitted from the emergency department to the ICU from November 2016 to February 2018. INTERVENTIONS: Patients were randomly assigned to a restrictive IV fluid resuscitation strategy (≤ 60 mL/kg of IV fluid) or usual care for the first 72 hours of care. MEASUREMENTS AND MAIN RESULTS: We enrolled 109 patients, of whom 55 were assigned to the restrictive resuscitation group and 54 to the usual care group. The restrictive group received significantly less resuscitative IV fluid than the usual care group (47.1 vs 61.1 mL/kg; p = 0.01) over 72 hours. By 30 days, there were 12 deaths (21.8%) in the restrictive group and 12 deaths (22.2%) in the usual care group (odds ratio, 1.02; 95% CI, 0.41-2.53). There were no differences between groups in the rate of new organ failure, hospital or ICU length of stay, or serious adverse events. CONCLUSIONS: This pilot study demonstrates that a restrictive resuscitation strategy can successfully reduce the amount of IV fluid administered to patients with severe sepsis and septic shock compared with usual care. Although limited by the sample size, we observed no increase in mortality, organ failure, or adverse events. These findings further support that a restrictive IV fluid strategy should be explored in a larger multicenter trial.

Comparison of Home-Based Oral Fluid Rapid HIV Self-Testing Versus Mail-in Blood Sample Collection or Medical/Community HIV Testing By Young Adult Black, Hispanic, and White MSM: Results from a Randomized Trial.

We aimed to determine in a randomized trial if young adult black, Hispanic, and white men-who-have-sex-with-men (YMSM) are more likely to complete home-based oral fluid rapid HIV self-testing than either mail-in blood sample collection or medical facility/community organization-based HIV testing. Stratified by race/ethnicity, participants were randomly assigned to use a free oral fluid rapid HIV self-test (n = 142), a free mail-in blood sample collection HIV test (n = 142), or be tested at a medical facility/community organization of their choice (n = 141). Of the 425 participants, completion of assigned test (66% oral fluid vs. 40% mail-in blood sample vs. 56% medical facility/community), willingness to refer (36% oral fluid vs. 20% mail-in blood sample vs. 26% medical facility/community), and legitimate referrals (58% oral fluid vs. 43% mail-in blood sample vs. 43% medical facility/community) were greater in the oral fluid rapid HIV self-test than the mail-in blood sample collection HIV test arm, but not the medical facility/community testing arm. There were no differences in assigned test completion by race/ethnicity. Although free home-based oral fluid rapid HIV self-testing showed moderate promise in facilitating HIV testing among black, Hispanic, and white YMSM, it did not lead to greater testing than directing these YMSM to medical facility/community HIV testing venues.

Discordance of voluntary HIV testing with HIV sexual risk-taking and self-perceived HIV infection risk among social media-using black, Hispanic, and white young-men-who-have-sex-with-men (YMSM).

Discordance between self-perceived HIV risk and actual risk-taking may impede efforts to promote HIV testing among young adult men-who-have-sex-with-men (YMSM) in the United States (US). Understanding the extent of, and reasons for, the discordance of HIV risk self-perception, HIV risk-taking and voluntary HIV testing among black, Hispanic and white YMSM could aid in the development of interventions to increase HIV testing among this higher HIV risk population. HIV-uninfected 18-24-year-old black, Hispanic, and white YMSM were recruited from across the US through multiple social media websites. Participants were queried about their voluntary HIV testing history, perception of currently having an undiagnosed HIV infection, and condomless anal intercourse (CAI) history. We assessed the association between previous CAI and self-perceived possibility of currently having an HIV infection by HIV testing status using Cochran-Mantel-Haenszel testing. Of 2275 black, Hispanic and white social media-using 18-24 year-old YMSM, 21% had never been tested for HIV voluntarily, 87% ever had CAI with another man, 77% believed that it was perhaps possible (as opposed to not possible at all) they currently could have an undiagnosed HIV infection, and 3% who reported CAI with casual or exchange partners, but had not been tested for HIV, self-perceived having no possibility of being HIV infected. Of 471 YMSM who had not been HIV tested, 57% reported CAI with casual or exchange partners, yet self-perceived having no possibility of being HIV infected. Per the Cochran-Mantel-Haenszel test results, among those reporting HIV risk behaviors, the self-perception of possibly being HIV-infected was not greater among those who had never been tested for HIV, as compared to those who had been tested. Future interventions should emphasize promoting self-realization of HIV risk and translating that into seeking and accepting voluntary HIV testing among this higher HIV risk population.

Lack of efficacy in a randomised trial of a brief intervention to reduce drug use and increase drug treatment services utilisation among adult emergency department patients over a 12-month period.

OBJECTIVES: Assess the 12-month efficacy of a brief intervention (BI) on reducing drug use and increasing drug treatment services utilisation among adult emergency department (ED) patients. METHODS: This randomised, controlled trial enrolled 18-64-year-old ED patients needing a drug use intervention. Treatment arm participants received a tailored BI while control arm participants only completed the study questionnaires. Self-reported past 3-month drug use and engagement in drug treatment services were compared by study arm at 3-month intervals over 1 year. Multiple imputations were performed to overcome loss-to-follow-up. RESULTS: Of the 1030 participants, follow-up completion ranged 55%-64% over the four follow-ups. At 12 months, the two study arms were similar in regards to mean: (1) proportion reporting any drug use (treatment: 67.1% (61.6 to 72.6), control: 74.4% (69.4 to 79.4)); (2) drug use frequency on a five-point scale (treatment: 3.7 (3.3 to 4.2), control: 4.6 (4.0 to 5.2)); (3) total days of drug use (treatment: 28.3 (23.2 to 33.4), control: 33.4 (28.5 to 38.2)); (4) most number of times drugs used/day (treatment: 4.6 (3.6 to 5.5), control: 6.1 (4.8 to 7.3)) and (5) typical number of times drugs used/day (treatment: 3.3 (2.5 to 4.1), control: 5.1 (3.9 to 6.2)). Utilisation of drug treatment services also was similar by study arm. In multivariable regression analyses, patients who were homeless or had higher drug use at baseline continued to have greater drug use in follow-up. CONCLUSIONS: Among adult ED patients requiring a drug use intervention, this BI did not decrease drug use or increase drug treatment services utilisation over a 12-month period more than the control condition. TRIAL REGISTRATION NUMBER: NCT01124591; Pre-trial.

Facilitating HIV/AIDS and HIV testing literacy for emergency department patients: a randomized, controlled, trial.

BACKGROUND: Although this has not been fully studied, videos and pictorial brochures might be equivalent methods of delivering HIV/AIDS and HIV testing information to emergency departments (ED) patients. It also is not known how well or for how long such knowledge is retained, if this information should be tailored according to patient health literacy, and if retention of this knowledge impacts future HIV testing behavior. METHODS: We will conduct a multi-site, randomized, controlled, longitudinal trial among 600 English- and 600 Spanish-speaking 18-64-year-old ED patients to investigate these questions. We will stratify our sample within language (English vs. Spanish) by health literacy level (lower vs. higher) and randomly assign patients to receive HIV/AIDS and HIV testing information by video or pictorial brochure. All patients will be tested for HIV in the ED. At 12-months post-enrollment, we will invite participants to be tested again for HIV. As primary aims, we will compare the efficacy of pictorial brochures and videos in improving short-term (in ED) HIV/AIDS and HIV testing knowledge and retaining this knowledge over 12 months. We will determine if and how short-term improvement and longer-term retention of knowledge interacts with information delivery mode (pictorial brochure or video), patient health literacy level (lower or higher), and language (English or Spanish). As secondary aims, using the Information-Motivation-Behavioral Skills (IMB) model as a heuristic framework, we will measure constructs from the IMB model relevant to our study, and assess their impact on HIV re-testing behavior; we will also examine the moderating influences of information delivery mode, language, and health literacy level. In addition, we will explore simplified screening strategies to identify ED patients with lower health literacy as ways to implement a tailored approach to HIV/AIDS and HIV testing information delivery in EDs. DISCUSSION: Study findings will guide ED-based delivery of HIV/AIDS and HIV testing information; that is, whether delivery modes (video or pictorial brochure) should be selected for patients by language and/or health literacy level. The results also will inform EDs when, how, and for whom information needs to be provided for those undergoing testing again for HIV within a one-year period.
