Assessment of self-harm risk using implicit thoughts.

Assessing for the risk of self-harm in acute care is a difficult task, and more information on pertinent risk factors is needed to inform clinical practice. This study examined the relationship of 6 forms of implicit cognition about death, suicide, and self-harm with the occurrence of self-harm in the future. We then attempted to develop a model using these measures of implicit cognition along with other psychometric tests and clinical risk factors. We conducted a prospective cohort of 107 patients (age > 17 years) with a baseline assessment that included 6 implicit association tests that assessed thoughts of death, suicide, and self-harm. Psychometric questionnaires were also completed by the patients, and these included the Beck Hopelessness Scale (Beck, Weissman, Lester, & Trexler, 1974), Barratt impulsiveness scale (Patton, Stanford, & Barratt, 1995), brief symptom inventory (Derogatis & Melisaratos, 1983), CAGE questionnaire for alcoholism (Ewing, 1984), and the drug abuse screening test 10 (Skinner, 1982). Medical and demographic information was also obtained for patients as potential confounders or useful covariables. The outcome measure was the occurrence of self-harm within 3 months. Implicit associations with death versus life as a predictor added significantly (odds ratio = 5.1, 95% confidence interval [1.3, 20.3]) to a multivariable model. The model had 96.6% sensitivity and 53.9% specificity with a high cutoff, or 58.6% sensitivity and 96.2% specificity with a low cutoff. This scale shows promise for screening emergency department patients with mental health presentations who may be at risk for future self-harm or suicide.

Brief emergency department interventions for youth who use alcohol and other drugs: a systematic review

Objective Brief intervention (BI) is recommended for use with youth who use alcohol and other drugs. Emergency departments (EDs) can provide BIs at a time directly linked to harmful and hazardous use. The objective of this systematic review was to determine the effectiveness of ED-based BIs. Methods We searched 14 electronic databases, a clinical trial registry, conference proceedings, and study references. We included randomized controlled trials with youth 21 years or younger. Two reviewers independently selected studies and assessed methodological quality. One reviewer extracted and a second verified data. We summarized findings qualitatively. Results Two trials with low risk of bias, 2 trials with unclear risk of bias, and 5 trials with high risk of bias were included. Trials evaluated targeted BIs for alcohol-positive (n = 3) and alcohol/other drug–positive youth (n = 1) and universal BIs for youth reporting recent alcohol (n = 4) or cannabis use (n = 1). Few differences were found in favor of ED-based BIs, and variation in outcome measurement and poor study quality precluded firm conclusions for many comparisons. Universal and targeted BIs did not significantly reduce alcohol use more than other care. In one targeted BI trial with high risk of bias, motivational interviewing (MI) that involved parents reduced drinking quantity per occasion and high-volume alcohol use compared with MI that was delivered to youth only. Another trial with high risk of bias reported an increase in abstinence and reduction in physical altercations when youth received peer-delivered universal MI for cannabis use. In 2 trials with unclear risk of bias, MI reduced drinking and driving and alcohol-related injuries after the ED visit. Computer-based MI delivered universally in 1 trial with low risk of bias reduced alcohol-related consequences 6 months after the ED visit. Conclusions Clear benefits of using ED-based BI to reduce alcohol and other drug use and associated injuries or high-risk behaviours remain inconclusive because of variation in assessing outcomes and poor study quality.

Emergency health care use and follow-up among sociodemographic groups of children who visit emergency departments for mental health crises

Background: Previous studies of differences in mental health care associated with children’s sociodemographic status have focused on access to community care. We examined differences associated with visits to the emergency department. Methods: We conducted a 6-year population-based cohort analysis using administrative databases of visits (n = 30 656) by children aged less than 18 years (n = 20 956) in Alberta. We measured differences in the number of visits by socioeconomic and First Nations status using directly standardized rates. We examined time to return to the emergency department using a Cox regression model, and we evaluated time to follow-up with a physician by physician type using a competing risks model. Results: First Nations children aged 15–17 years had the highest rate of visits for girls (7047 per 100 000 children) and boys (5787 per 100 000 children); children in the same age group from families not receiving government subsidy had the lowest rates (girls: 2155 per 100 000 children; boys: 1323 per 100 000 children). First Nations children (hazard ratio [HR] 1.64; 95% confidence interval [CI] 1.30–2.05), and children from families receiving government subsidies (HR 1.60, 95% CI 1.30–1.98) had a higher risk of return to an emergency department for mental health care than other children. The longest median time to follow-up with a physician was among First Nations children (79 d; 95% CI 60–91 d); this status predicted longer time to a psychiatrist (HR 0.47, 95% CI 0.32–0.70). Age, sex, diagnosis and clinical acuity also explained post-crisis use of health care. Interpretation: More visits to the emergency department for mental health crises were made by First Nations children and children from families receiving a subsidy. Sociodemographics predicted risk of return to the emergency department and follow-up care with a physician.

Instruments to Detect Alcohol and Other Drug Misuse in the Emergency Department: A Systematic Review

CONTEXT: Alcohol and other drug (AOD) misuse by youth is a significant public health concern. Unanticipated treatment for AOD-related morbidities is often sought in hospital emergency departments (EDs). Screening instruments that rapidly identify patients who require further diagnostic evaluation and/or brief intervention are critically important. OBJECTIVE: To summarize evidence on screening instruments that can assist emergency care clinicians in identifying AOD misuse in pediatric patients. METHODS: Fourteen electronic databases (including Medline, Embase, and PsycINFO) and reference screening were used. Psychometric and prospective diagnostic studies were selected if the instrument focused on detecting AOD misuse in patients aged 21 years or younger in the ED. Two reviewers independently assessed quality and extracted data. Validity and reliability data were collected for psychometric studies. Instrument performance was assessed by using sensitivity, specificity, and positive (LR+) and negative (LR−) likelihood ratios. Meta-analysis was not possible because of clinical and measurement heterogeneity. RESULTS: Of the 1545 references initially identified, 6 studies met inclusion criteria; these studies evaluated 11 instruments for universal or targeted screening of alcohol misuse. Instruments based on diagnostic criteria for AOD disorders were effective in detecting alcohol abuse and dependence (sensitivity: 0.88; specificity: 0.90; LR+: 8.80) and cannabis use disorder (sensitivity: 0.96; specificity: 0.86; LR+: 6.83). CONCLUSIONS: On the basis of the current evidence, we recommend that emergency care clinicians use a 2-question instrument for detecting youth alcohol misuse and a 1-question instrument for detecting cannabis misuse. Additional research is required to definitively answer whether these tools should be used as targeted or universal screening approaches in the ED.

Temporal trends in pediatric mental health visits: using longitudinal data to inform emergency department health care planning

Objective Understanding the temporality of mental health presentations to the emergency department (ED) during the 24-hour cycle, day of the week, and month of the year may facilitate strategic planning of ED-based mental health services. Methods Data on 30,656 ED presentations for mental illness, substance use, or intentional self-harm by 20,956 patients (⩽17 years) were examined. We studied patient demography, discharge diagnosis, and time and date of presentation. Results Most pediatric mental health ED visits (66.0%) occurred after the average work and school day (after 5 PM). Presentations related to substance use and intentional self-harm steadily increased in the evening. Emergency department visits related to substance use peaked on Friday through Sunday (4723/7475; 63.2%), whereas visits for mood disorders (4127/5093; 81.0%), neurotic/stress-related disorders (5960/7989; 74.6%), and behavioral/emotional disorders (237/304; 78%) were highest during the work/school week (Monday to Friday). Visits for intentional self-harm peaked following the weekend (Monday: 771/4676; 16.5%). Summer months had fewer visits (6862/30,656; 22.4%), whereas March to May (range: 2752–2912 visits) and October to November (range: 2701–2751 visits) showed more steady peaks in volume. Most presentations by diagnostic group decreased in volume during the winter months (December to February) to increase again in the spring (March to May). Conclusions Peak times for pediatric mental health presentations to the ED are evenings throughout the week, suggesting that mental health services for children, adolescents, and their families should be available after work and school hours, 7 days a week.

Enhancing screening, brief intervention, and referral to treatment among socioeconomically disadvantaged patients: study protocol for a knowledge exchange intervention involving patients and physicians

BackgroundScreening, Brief Intervention, and Referral for Treatment (SBIRT) is an effective approach for managing alcohol and other drug misuse in primary care; however, uptake into routine care has been limited. Uptake of SBIRT by healthcare providers may be particularly problematic for disadvantaged populations exhibiting alcohol and other drug problems, and requires creative approaches to enhance patient engagement. This knowledge translation project developed and evaluated a group of patient and health care provider resources designed to enhance the capacity of health care providers to use SBIRT and improve patient engagement with health care.Methods/DesignA nonrandomized, two-group, pre-post, quasi-experimental intervention design was used, with baseline, 6-, and 12-month follow-ups. Low income patients using alcohol and other drugs and who sought care in family medicine and emergency medicine settings in Edmonton, Canada, along with physicians providing care in these settings, were recruited. Patients and physicians were allocated to the intervention or control condition by geographic location of care. Intervention patients received a health care navigation booklet developed by inner city community members and also had access to an experienced community member for consultation on health service navigation. Intervention physicians had access to online educational modules, accompanying presentations, point of care resources, addiction medicine champions, and orientations to the inner city. Resource development was informed by a literature review, needs assessment, and iterative consultation with an advisory board and other content experts. Participants completed baseline and follow-up questionnaires (6 months for patients, 6 and 12 months for physicians) and administrative health service data were also retrieved for consenting patients. Control participants were provided access to all resources after follow-up data collection was completed. The primary outcome measure was patient satisfaction with care; secondary outcome measures included alcohol and drug use, health care and addiction treatment use, uptake of SBIRT strategies, and physician attitudes about addiction.DiscussionEffective knowledge translation requires careful consideration of the intended knowledge recipient’s context and needs. Knowledge translation in disadvantaged settings may be optimized by using a community-based participatory approach to resource development that takes into account relevant patient engagement issues.Trial registrationNorthern Alberta Clinical Trials and Research Centre #30094

A Survey of Caregiver Perspectives on Children's Pain Management in the Emergency Department.

OBJECTIVES We explored caregiver perspectives on their childrens pain management in both a pediatric (PED) and general emergency department (GED). Study objectives were to: (1) measure caregiver estimates of childrens pain scores and treatment; (2) determine caregiver level of satisfaction; and (3) determine factors associated with caregiver satisfaction. METHODS This prospective survey examined a convenience sample of 97 caregivers (n=51 PED, n=46 GED) with children aged <17 years. A paper-based survey was distributed by research assistants, from 2009-2011. RESULTS Most caregivers were female (n=77, 79%) and were the childs mother (n=69, 71%). Children were treated primarily for musculoskeletal pain (n=41, 42%), headache (n=16, 16%) and abdominal pain (n=7, 7%). Using a 100 mm Visual Analog Scale, the maximum mean reported pain score was 75 mm (95% CI: 70-80) and mean score at discharge was 39 mm (95% CI: 32-46). Ninety percent of caregiver respondents were satisfied (80/89, 90%); three (3/50, 6%) were dissatisfied in the PED and six (6/39, 15%) in the GED. Caregivers who rated their childs pain at ED discharge as severe were less likely to be satisfied than those who rated their childs pain as mild or moderate (p=0.034). CONCLUSIONS Despite continued pain upon discharge, most caregivers report being satisfied with their childs pain management. Caregiver satisfaction is likely multifactorial, and physicians should be careful not to interpret satisfaction as equivalent to adequate provision of analgesia. The relationship between satisfaction and pain merits further exploration.

Experiences of pediatric emergency physicians in providing alcohol-related care to adolescents in the emergency department.

Objective The emergency department (ED) is a key clinical care setting for identifying and managing patients with alcohol-related presentations. We explored the experiences of emergency physicians in providing alcohol-related care to adolescents. Methods Purposeful sampling was used to identify pediatric emergency physicians with at least 1 year of experience (n = 12) from pediatric EDs across Canada. Data were collected via telephone using a semistructured interview guide. Hermeneutic phenomenology was used to identify common and unique experiences among respondents, using Moustakas’ immersion/crystallization procedures. Results Physicians expressed frustration with patient behaviors accompanying intoxication and described providing care as a struggle; developing an effective therapeutic alliance was challenging. Physicians believed intoxicated adolescent patients required more clinical time and resources than they could offer. Although physicians described the ED as unsuitable for ensuring continuity of care and addressing the broader social issues that accompany alcohol use, they did view the ED as a place to medically stabilize the patient and initiate a discussion on alcohol use and its harmful effects. Conclusions Pediatric ED physicians struggled during the caring experience and were skeptical that broader, more chronic social issues that are often associated with adolescent alcohol misuse can be effectively managed in a clinical setting where they feel primarily responsible for providing medical stabilization. Physicians did believe the ED was an appropriate place to ensure medical stability of a patient and then initiate a conversation regarding alcohol use and its harmful effects.

Attitudes and Beliefs towards Patients with Hazardous Alcohol Use: A Systematic Review

Objective. To describe emergency department (ED) staff attitudes and beliefs towards patients presenting with hazardous alcohol use and their clinical management. Methods. A search of MEDLINE, EMBASE, CINAHL, SCOPUS from 1990 to 2010, and reference lists from included studies was conducted. Two reviewers independently screened for inclusion and assessed study quality. One reviewer extracted the data and a second checked for completeness and accuracy. Results. Among nine studies four reported varied beliefs on whether screening was worthwhile for identifying hazardous alcohol use (physicians: 42%–88%; nurses: 50%–100%). Physicians in three studies were divided on intervention provision (32%–54% in support of intervention provision) as were nurses in two studies (39% and 64% nurses in support of intervention provision). Referral for treatment was identified in two studies as an important part of ED management (physicians: 62% and 97%; nurses: 95%). Other attitudes and beliefs identified across the studies included concern that asking about alcohol consumption would be seen as obtrusive or offensive, and a perceived lack of time and resources available for providing care and referrals. Conclusions. ED staff had varying attitudes towards ED management of patients with hazardous alcohol use. Investigations into improving clinical care for hazardous alcohol use are needed to optimize ED management for these patients.

A cohort study of unstable overdose patients treated with intravenous lipid emulsion therapy.

OBJECTIVES Intravenous lipid emulsion (ILE) has been used increasingly over the last decade for a range of drug overdoses. Although the use of ILE in local anesthetic toxicity (LAST) is well established, the hemodynamic effectiveness of ILE in non-LAST poisonings is still unclear. Thus, the primary objective of this study was to examine a cohort of poisoned patients in whom ILE was administered. METHODS Consecutive patients were identified by calls to a regional poison center from May 1, 2012 to May 30, 2014. Patients were enrolled if they ingested a drug, developed hemodynamic instability, failed conventional treatment, and received ILE therapy. Data were collected by medical record review. The primary outcome was the change in mean arterial pressure (MAP) in the first hour after ILE administration. Secondary outcomes included survival, length of stay, and the effect of drug class on patient outcome. RESULTS Thirty-six patients were enrolled. Agents ingested included calcium channel blockers and beta blockers (10/36, 27.8%), tricyclic antidepressants (5/36, 13.9%), bupropion (3/36, 8.3%), and antiepileptic agents (1/36, 2.8%). Seventeen patients (47.2%) ingested multiple agents. Twenty-five patients survived (69.0%). Overall, MAP increased by 13.79 mm Hg (95% CI 1.43-26.15); this did not meet our a priori definition of clinical significance. CONCLUSIONS Our study did not find a clinically important improvement in MAP after ILE administration. Until future research is done to more definitively study its efficacy, ILE should remain a potential treatment option for hemodynamically unstable overdose patients only after conventional therapy has failed.
