Sudden-Onset Disaster Mass-Casualty Incident Response: A Modified Delphi Study on Triage, Prehospital Life Support, and Processes.

The application and provision of prehospital care in disasters and mass-casualty incident response in Europe is currently being explored for opportunities to improve practice. The objective of this translational science study was to align common principles of approach and action and to identify how technology can assist and enhance response. To achieve this objective, the application of a modified Delphi methodology study based on statements derived from key findings of a scoping review was undertaken. This resulted in 18 triage, eight life support and damage control interventions, and 23 process consensus statements. These findings will be utilized in the development of evidence-based prehospital mass-casualty incident response tools and guidelines.

The Management of Children and Youth With Pediatric Mental and Behavioral Health Emergencies.

Mental and behavioral health (MBH) emergencies in children and youth continue to increasingly affect not only the emergency department (ED), but the entire spectrum of emergency medical services for children, from prehospital services to the community. Inadequate community and institutional infrastructure to care for children and youth with MBH conditions makes the ED an essential part of the health care safety net for these patients. As a result, an increasing number of children and youth are referred to the ED for evaluation of a broad spectrum of MBH emergencies, from depression and suicidality to disruptive and aggressive behavior. However, challenges in providing optimal care to these patients include lack of personnel, capacity, and infrastructure, challenges with timely access to a mental health professional, the nature of a busy ED environment, and paucity of outpatient post-ED discharge resources. These factors contribute to prolonged ED stays and boarding, which negatively affects patient care and ED operations. Strategies to improve care for MBH emergencies, including systems level coordination of care, is therefore essential. The goal of this policy statement and its companion technical report is to highlight strategies, resources, and recommendations for improving emergency care delivery for pediatric MBH.

Inter-Rater Reliability and Agreement Among Mass-Casualty Incident Algorithms Using a Pediatric Trauma Dataset: A Pilot Study.

INTRODUCTION: Many triage algorithms exist for use in mass-casualty incidents (MCIs) involving pediatric patients. Most of these algorithms have not been validated for reliability across users. STUDY OBJECTIVE: Investigators sought to compare inter-rater reliability (IRR) and agreement among five MCI algorithms used in the pediatric population. METHODS: A dataset of 253 pediatric (<14 years of age) trauma activations from a Level I trauma center was used to obtain prehospital information and demographics. Three raters were trained on five MCI triage algorithms: Simple Triage and Rapid Treatment (START) and JumpSTART, as appropriate for age (combined as J-START); Sort Assess Life-Saving Intervention Treatment (SALT); Pediatric Triage Tape (PTT); CareFlight (CF); and Sacco Triage Method (STM). Patient outcomes were collected but not available to raters. Each rater triaged the full set of patients into Green, Yellow, Red, or Black categories with each of the five MCI algorithms. The IRR was reported as weighted kappa scores with 95% confidence intervals (CI). Descriptive statistics were used to describe inter-rater and inter-MCI algorithm agreement. RESULTS: Of the 253 patients, 247 had complete triage assignments among the five algorithms and were included in the study. The IRR was excellent for a majority of the algorithms; however, J-START and CF had the highest reliability with a kappa 0.94 or higher (0.9-1.0, 95% CI for overall weighted kappa). The greatest variability was in SALT among Green and Yellow patients. Overall, J-START and CF had the highest inter-rater and inter-MCI algorithm agreements. CONCLUSION: The IRR was excellent for a majority of the algorithms. The SALT algorithm, which contains subjective components, had the lowest IRR when applied to this dataset of pediatric trauma patients. Both J-START and CF demonstrated the best overall reliability and agreement.

Differences in Comorbidities Between Children and Youth With Suicide Attempts Versus Ideation Presenting to the Emergency Department.

OBJECTIVE: The aim of this work was to explore identified risk factors for suicidal ideations and attempts and the differences in these risk factors between emergency department encounters among youth seeking medical care for suicide attempt and those with suicidal ideation. METHOD: This was a retrospective analysis of suicide-related claims for emergency department visits from nine state-level Healthcare Cost and Utilization Project databases for youth aged 5 through 19 years. Risk factors were estimated by identifying comorbidities recorded in first five diagnosis codes. Odds ratios comparing rates of these comorbidities in encounters for suicide attempts compared to encounters for suicidal ideation were estimated using multivariate logistic regression. RESULTS: In all, 169,047 encounters for suicide-related behavior were identified. We found higher odds of concurrent anxiety, personality disorders, and alcohol-related diagnoses and lower odds of a comorbid psychosis diagnosis, attention deficit hyperactivity disorder, and other substance-related diagnoses in the population of suicide attempters compared to patients with suicidal ideation alone. CONCLUSION: The odds of diagnoses of specific comorbidities differed in youth encounters for suicide attempts compared to encounters for suicidal ideation.

Comparison of Outcome Tools Used to Test Mass-Casualty Algorithms in the Pediatric Population.

INTRODUCTION: Mass-casualty incident (MCI) algorithms are used to sort large numbers of patients rapidly into four basic categories based on severity. To date, there is no consensus on the best method to test the accuracy of an MCI algorithm in the pediatric population, nor on the agreement between different tools designed for this purpose. STUDY OBJECTIVE: This study is to compare agreement between the Criteria Outcomes Tool (COT) to previously published outcomes tools in assessing the triage category applied to a simulated set of pediatric MCI patients. METHODS: An MCI triage category (black, red, yellow, and green) was applied to patients from a pre-collected retrospective cohort of pediatric patients under 14 years of age brought in as a trauma activation to a Level I trauma center from July 2010 through November 2013 using each of the following outcome measures: COT, modified Baxt score, modified Baxt combined with mortality and/or length-of-stay (LOS), ambulatory status, mortality alone, and Injury Severity Score (ISS). Descriptive statistics were applied to determine agreement between tools. RESULTS: A total of 247 patients were included, ranging from 25 days to 13 years of age. The outcome of mortality had 100% agreement with the COT black. The "modified Baxt positive and alive" outcome had the highest agreement with COT red (65%). All yellow outcomes had 47%-53% agreement with COT yellow. "Modified Baxt negative and <24 hours LOS" had the highest agreement with the COT green at 89%. CONCLUSIONS: Assessment of algorithms for triaging pediatric MCI patients is complicated by the lack of a gold standard outcome tool and variability between existing measures.

ACEP SimBox: A Pediatric Simulation-Based Training Innovation.

Thirty million pediatric visits (<18 years old) occur across 5,000 US emergency departments (EDs) each year, with most of these cases presenting to community EDs. Simulation-based training is an effective method to improve and sustain EDs' readiness to triage and stabilize critically ill infants and children, but large simulation centers are mostly concentrated at academic hospitals. The use of pediatric simulation-based training has been limited in the community ED setting due to the high cost of equipment and limited access to content experts in pediatric critical care. We designed an innovative "off-the-shelf" simulation-based training resource, "American College of Emergency Physicians (ACEP) SimBox," that provides a free low-technology manikin along with teaching aids and train-the-trainer materials to community EDs to run a simulation drill in their own workspaces with local educators. The goal was to develop an "off-the-shelf," free, open-access, simulation-based resource to improve the readiness of community EDs to triage, resuscitate, and transfer critically ill infants as measured by presimulation and postsimulation surveys measuring opinions regarding the scenario, session experience, and most valuable aspect of the session. Between January 2018 and December 2019, 179 ACEP SimBoxes were shipped across the United States, reaching 36 of 50 states. Facilitators and participants who completed the postsimulation survey evaluated the session as a valuable use of their time. All facilitator respondents reported that the low-technology manikins, paired with their institution-specific equipment, were sufficient for learning, thus reducing costs. All participant respondents reported an increased commitment to pediatric readiness for their ED after completing the simulation session. This innovation resulted in the implementation of a unique simulation-based training intervention across many community EDs in the United States. The ACEP SimBox innovation demonstrates that an easy to use and unique simulation-based training tool can be developed, distributed, and implemented across many community EDs in the United States to help improve community ED pediatric readiness.

Decline in Pediatric Emergency Department Behavioral Team Activations After Institution of an Agitation Protocol.

OBJECTIVE: Aggressive behavior among pediatric patients with psychiatric complaints in emergency departments is a growing problem. An agitation protocol was instituted in 1 pediatric emergency department to provide scaled recommendations for differing levels of aggression. The study objective was to determine if the frequency of activation of an emergency behavioral response team changed after protocol initiation. METHODS: A protocol for escalating management of agitation in pediatric patients was introduced in February 2016. The electronic medical record was queried for subsequent behavioral response team activations over the next 16 months. Patient demographics and specific features surrounding the activation were retrospectively recorded from the medical record, including length of stay, medications administered, and documented deescalation techniques. Frequency and features of behavioral team activations were compared with activations from a period before the planning and implementation of the protocol (May 2014 to May 2015). RESULTS: Twenty-one patient visits were found to require behavioral response team activation over 16 months, compared with 31 for the 13-month preprotocol period. Attempts at verbal/ environmental redirection were seen in 77% and deescalation by medication administration before the activation occurred in 14% of patients. During the behavioral team activation, 81% of the patients were given psychiatric medications and 81% were placed in physical restraints. CONCLUSIONS: A decrease from a baseline of 2.4 to 1.3 behavioral response team activations per month, or a 46% decline, was noted following the institution of a clinical protocol for pediatric agitation.

Prevalence of marijuana use among trauma patients before and after legalization of medical marijuana: The Arizona experience.

BACKGROUND: In recent years, marijuana has become legal for use in many states, for either medicinal or recreational purposes. Objective: The primary objective is to determine if legalization of medical marijuana is associated with an increased use among trauma patients. Methods: Prospective observational study included three periods; (pre-legalization; period 1); legal to grow for medicinal purposes but no dispensaries open (period 2); and legal to purchase medicinal marijuana in a dispensary (period 3). The study included all adult trauma patients presenting to an urban level I trauma center in Phoenix, AZ. The prevalence of use (as defined by positive urine drug screen or self-reporting) in each time period was determined and compared using two sample tests of proportion. Confidence intervals for prevalence (self-reporting only) were compared with published age matched data from the same geographical region of the general population. Results: The prevalence of marijuana use increased significantly from pre-legalization (period 1) to post legalization (periods 2 and 3), but there was no significant change between the two post legalization periods. After controlling for age and sex, the odds of being marijuana positive post-legalization vs. pre-legalization was 1.36, p = 0.006 95%CI [1.09-1.7]. Overall, the prevalence of marijuana among trauma patients was nearly four-fold higher than the population as a whole in the same geographic region. Patients who use marijuana are more likely to use cocaine or amphetamine (OR 2.31; 95% CI 1.86-2.89) or had an ethanol level above 80 mg/dL (OR 1.57; 95% CI 1.32-1.87). Conclusion: The legalization of medicinal marijuana is associated with significantly increased prevalence among trauma patients. It appears that legalization, rather than the convenience of dispensaries, is associated with an increase in use.

Occult Pneumothorax Identification on Extended Focused Assessment with Sonography for Trauma Examination in Children.

OBJECTIVE: Occult pneumothoraces (OPTXs) are defined by air within the pleural space that is not visible on conventional chest radiographs (CXR). The aim of this study was to understand how frequently the Extended Focused Assessment with Sonography for Trauma (eFAST) examination identifies occult PTX in a pediatric blunt trauma population as compared with a criterion standard of chest computed tomography (CCT). METHODS: This study is a secondary analysis of blunt trauma patients younger than 18 years who underwent CCT at Los Angeles County +USC Medical Center Emergency Department from October 2015 to April 2017. The eFAST examination was performed and documented by an emergency medicine resident with attending oversight or by an emergency medicine attending for each trauma. The eFAST results were reviewed for patients diagnosed with small or trace pneumothoraces identified on CCT. RESULTS: Of 168 pediatric trauma patients undergoing CCT, 16 had OPTXs not seen on CXR and 4 patients had a small/trace PTX without a corresponding CXR performed. None were identified on eFAST. CONCLUSIONS: Although the sample size in this data set was small, our eFAST examinations identified none of 16 proven and 4 presumed OPTXs. The standard eFAST examination performed poorly in the detection of OPTXs in this single-center study of pediatric blunt trauma victims.

Association Between Race/Ethnicity and Disparities in Health Care Use Before First-Episode Psychosis Among Privately Insured Young Patients.

Importance: Racial/ethnic disparities in health care use and clinical outcomes for behavioral health disorders, including psychosis, are well documented, but less is known about these disparities during the period leading up to first-episode psychosis (FEP). Objective: To describe the racial/ethnic disparities in behavioral health care use and prescription drug use of children and young adults before the diagnosis of FEP. Design, Setting, and Participants: An observational cohort study was conducted using medical and prescription drug claims from January 1, 2007, to September 30, 2015, obtained from Optum's deidentified Clinformatics Data Mart Database, a commercial claims database augmented with race/ethnicity and socioeconomic variables. Data analysis was performed from February 6, 2018, to October 10, 2020. First-episode psychosis was determined by the presence of psychosis diagnoses on claims for at least 1 hospitalization or 2 outpatient events, with a continuous enrollment requirement of at least 2 years before the first diagnosis. Participants included 3017 Black, Hispanic, or White patients who were continually enrolled in commercial insurance plans and received an FEP diagnosis between the ages of 10 and 21 years. Main Outcomes and Measures: Race/ethnicity was determined from a commercial claims database. Rates of inpatient admission, emergency department presentation, and outpatient visits (including psychotherapy), behavioral health disorder diagnoses, and antipsychotic/antidepressant prescription fills were determined for the year before FEP. Race/ethnicity was also obtained from Optum's claims database. With use of multivariable logistic regression, results were adjusted for covariates including estimated household income, age, sex, and geographic division in the US. Results: Of the 3017 patients with FEP, 643 Black or Hispanic patients (343 [53.3%] Black, 300 [46.7%] Hispanic, 324 [50.4%] male, mean [SD] age, 17.2 [2.76] years) were less likely than 2374 White patients (1210 [51.0%] male, mean age, 17.0 [2.72] years) to receive comorbid behavioral health disorder diagnoses in the year before the diagnosis of FEP (410 [63.8%] vs 1806 [76.1%], χ2 = 39.3; P < .001). Except for emergency care, behavioral health care use rates were lower in Black and Hispanic patients vs White patients (424 [65.9%] vs 1868 [78.7%]; χ2 = 45.0; P < .001), particularly for outpatient visits with behavioral health care professionals (232 [36.1%] vs 1236 [52.1%]; χ2 = 51.7; P < .001). After adjustment for socioeconomic covariates, behavioral health care use rates (68.9% vs 79.2%; P < .001), outpatient visits with behavioral health professionals (37.7% vs 51.2%; P < .001), and other outcomes remained significantly lower for Black and Hispanic patients vs White patients. Conclusions and Relevance: The results of this study extend existing research findings of well-known racial/ethnic disparities in the population of patients who are diagnosed with FEP. These differences were apparent in young patients with continuous commercial health insurance and after controlling for household income. Providing equal access to preventive outpatient behavioral health care may increase opportunities for timely detection of psychotic symptoms and early intervention and improve differential outcomes after FEP.

Tabletop Application of SALT Triage to 10, 100, and 1000 Pediatric Victims.

INTRODUCTION: The Sort, Access, Life-saving interventions, Treatment and/or Triage (SALT) mass-casualty incident (MCI) algorithm is unique in that it includes two subjective questions during the triage process: "Is the victim likely to survive given the resources?" and "Is the injury minor?" HYPOTHESIS/PROBLEM: Given this subjectivity, it was hypothesized that as casualties increase, the inter-rater reliability (IRR) of the tool would decline, due to an increase in the number of patients triaged as Minor and Expectant. METHODS: A pre-collected dataset of pediatric trauma patients age <14 years from a single Level 1 trauma center was used to generate "patients." Three trained raters triaged each patient using SALT as if they were in each of the following scenarios: 10, 100, and 1,000 victim MCIs. Cohen's kappa test was used to evaluate IRR between the raters in each of the scenarios. RESULTS: A total of 247 patients were available for triage. The kappas were consistently "poor" to "fair:" 0.37 to 0.59 in the 10-victim scenario; 0.13 to 0.36 in the 100-victim scenario; and 0.05 to 0.36 in the 1,000-victim scenario. There was an increasing percentage of subjects triaged Minor as the number of estimated victims increased: 27.8% increase from 10- to 100-victim scenario and 7.0% increase from 100- to 1,000-victim scenario. Expectant triage categorization of patients remained stable as victim numbers increased. CONCLUSION: Overall, SALT demonstrated poor IRR in this study of increasing casualty counts while triaging pediatric patients. Increased casualty counts in the scenarios did lead to increased Minor but not Expectant categorizations.

Discontinuing involuntary mental health holds for children: Does psychiatrist specialty matter? A pilot study.

BACKGROUND: Involuntary mental health detainments should only be utilized when less restrictive alternatives are unavailable and should be discontinued as soon as safety can be ensured. The study objective was to determine if child and adolescent psychiatrists discontinue a greater proportion of involuntary holds than general psychiatrists for similar pediatric patients. METHODS: Retrospective analysis of consecutive patients under 18 years placed on an involuntary hold in the prehospital setting presenting over a 1-year period to one high-volume emergency department (ED) where youth on involuntary holds are seen by child and adolescent psychiatrists when available and general psychiatrists otherwise. The primary outcome of interest was hold discontinuation after initial psychiatric consultation. The key predictor of interest was psychiatrist specialty (child and adolescent vs. general). We conducted multivariate logistic regression modeling adjusting for patient characteristics and time of arrival. RESULTS: Child and adolescent psychiatrists discontinued 27.4% (51/186) of prehospital holds while general psychiatrists discontinued only 10.6% (22/207). After adjusting for observable confounders, holds were over 3 times as likely to be discontinued in patients evaluated by child and adolescent psychiatrists rather than general emergency psychiatrists (adjusted OR 3.2, 95% CI 1.7-5.9, p < 0.001). CONCLUSIONS: Child and adolescent psychiatrists are much more likely to discontinue prehospital involuntary mental health holds compared with general emergency psychiatrists. While inappropriate hold discontinuation places patients at risk of harm, prolonged hold continuation limits patients' rights and potentially increases psychiatric boarding in EDs. Earlier access to child and adolescent psychiatry may facilitate early hold discontinuation and standardize patient care.

Marijuana self-report compared with testing in trauma patients before and after legalization.

Background: Both marijuana use and legalization are increasing, and the cognitive effects of marijuana may play a role in trauma. Our objective was to assess the proportion of patients with a urine drug screen who self-reported use in a population of trauma patients.Methods: Self-report of marijuana use in trauma patients was recorded for patients with a positive urine toxicology screen at a Level 1 trauma center in Arizona prior to (1/2011 to 4/13/2011) and following (4/14/2011 to 9/2014) legalization of marijuana for medical indications.Results: Among patients with a positive toxicology screen who were able to report to utilization, 52.5% patients with a positive UDS for marijuana overall reported use. In the pre-legalization group, 59.3% reported use, while in the post-legalization group, 51.4% reported use (p = .188).Conclusion: Only about half of trauma patients with a positive urine drug screen for marijuana reported use. Self-reporting among UDS-positive patients demonstrated no significant change with the legalization of marijuana for medical reasons.

Review of Interventions and Radiation Exposure from Chest Computed Tomography in Children with Blunt Trauma.

OBJECTIVE: To determine the radiation risk to a child undergoing trauma evaluation with chest computed tomography (CCT) for every clinically actionable injury identified. STUDY DESIGN: This observational, cross-sectional study included all blunt trauma patients under 18 years of age undergoing CCT in a single urban emergency department. Via a retrospective chart review, therapeutic interventions done exclusively for chest injuries identified on CCT scan were identified. Effective radiation from each CCT was calculated and averaged and the dose required to diagnose 1 management-changing chest injury was determined. RESULTS: Of 209 children undergoing CCT over a 19-month period, 168 were victims of blunt trauma. Ten required an intervention specifically for a chest injury identified on CCT (suggesting development of 1 malignancy per 37 actionable injures identified). None required an intervention for an injury exclusively noted on CCT, as all 10 actionable injuries were apparent via other modalities (radiograph, ultrasound examination, clinical examination). CONCLUSION: Although 10 uniquely actionable injuries were identified on CCT, none were found only on CCT. Because CCTs rarely modified management, the amount of radiation administered per management change was sufficiently high to recommend reconsideration of current imaging practice in this single-center study.

Flipping the Classroom in Medical Student Education: Does Priming Work?

INTRODUCTION: The emergency medicine (EM) clerkship curriculum at Los Angeles County + University of Southern California Medical Center includes monthly lectures on pediatric fever and shortness of breath (SOB). This educational innovation evaluated if learning could be enhanced by "priming" the students with educational online videos prior to an in-class session. Factors that impacted completion rates were also evaluated (planned specialty and time given for video viewing). METHODS: Twenty-minute videos were to be viewed prior to the didactic session. Students were assigned to either the fever or SOB group and received links to those respective videos. All participating students took a pre-test prior to viewing the online lectures. For analysis, test scores were placed into concordant groups (test results on fever questions in the group assigned the fever video and test results on SOB questions in the group assigned the SOB video) and discordant groups (crossover between video assigned and topic tested). Each subject contributed one set of concordant results and one set of discordant results. Descriptive statistics were performed with the Mann-Whitney U test. Lecture links were distributed to students two weeks prior to the in-class session for seven months and three days prior to the in-class session for eight months (in which both groups included both EM-bound and non-EM bound students). RESULTS: In the fifteen-month study period, 64% of students rotating through the EM elective prepared for the in class session by watching the videos. During ten months where exclusively EM-bound students were rotating (n=144), 71.5% of students viewed the lectures. In four months where students were not EM-bound (n=54), 55.6% of students viewed the lectures (p=0.033). Participation was 60.2% when lecture links were given three days in advance and 68.7% when links were given two weeks in advance (p=0.197). In the analysis of concordant scores, the pre-test averaged 56.7% correct, the immediate post-test averaged 78.1% correct, and the delayed post-test was 67.2%. In the discordant groups, the pretest averaged 51.9%, the immediate posttest was 67.1% and the delayed by 68.8%. In the concordant groups, the immediate post-test scores improved by 21.4%, compared with 15.2% in the discordant groups (p = 0.655). In the delayed post-test the concordant scores improved by 10.5% and discordant scores by 16.9 percent (p=0.609). Sixty-two percent of students surveyed preferred the format of online videos with in-class case discussion to a traditional lecture format. CONCLUSION: Immediate post-tests and delayed post-tests improved but priming was not demonstrated to be a statistically superior educational method in this study. Medical student completion of the preparatory materials for the EM rotation session increased when the students were EM-bound. Participation rates were not significantly different when given at two weeks versus three days.

The Utility of Cranial Ultrasound for Detection of Intracranial Hemorrhage in Infants.

OBJECTIVE: The objective of this study was to evaluate the sensitivity and specificity of cranial ultrasound (CUS) for detection of intracranial hemorrhage (ICH) in infants with open fontanels. METHODS: This was a retrospective study of infants younger than 2 years who had a CUS performed for the evaluation of potential ICH. We excluded patient with CUSs that were done for reasons related to prematurity, transplant or oncologic evaluations, routine follow-up or preoperative screen, or congenital and known perinatal anomalies. Two clinicians independently classified each of the patients with ICH into significant or insignificant based on the radiology reports. RESULTS: Of 4948 CUS studies performed during the 5-year study period, 283 studies fit the inclusion criteria. Patient age ranged from 0 to 458 days, with a median of 33 days. There were 39 total cases of ICH detected, with 27 significant bleeds and 12 insignificant bleeds. Using computed tomography, magnetic resonance imaging, or clinical outcome as criterion standard, the overall ultrasound sensitivity and specificity for bleed were 67% (confidence interval [CI], 50%-81%) and 99% (CI, 97%-100%), respectively. For those with significant bleeds, the overall sensitivity was 81% (CI, 62%-94%), and for those with insignificant bleeds, it was 33% (CI, 1%-65%). CONCLUSIONS: The sensitivity of CUS is inadequate to justify its use as a screening tool for detection of ICH in young infants.

Case-controlled Analysis of Patient-based Risk Factors for Assault in the Healthcare Workplace.

INTRODUCTION: Violence against healthcare workers in the medical setting is common and associated with both physical and psychological adversity. The objective of this study was to identify features associated with assailants to allow early identification of patients at risk for committing an assault in the healthcare setting. METHODS: We used the hospital database for reporting assaults to identify cases from July 2011 through June 2013. Medical records were reviewed for the assailant's (patient's) past medical and social history, primary medical complaints, ED diagnoses, medications prescribed, presence of an involuntary psychiatric hold, prior assaultive behavior, history of reported illicit drug use, and frequency of visits to same hospital requesting prescription for pain medications. We selected matched controls at random for comparison. The primary outcome measure(s) reported are features of patients committing an assault while undergoing medical or psychiatric treatment within the medical center. RESULTS: We identified 92 novel visits associated with an assault. History of an involuntary psychiatric hold was noted in 52%, history of psychosis in 49%, a history of violence in the ED on a prior visit in 45%, aggression at index visit noted in the ED chart in 64%, an involuntary hold (or consideration of) for danger to others in 61%, repeat visits for pain medication in 9%, and history of illicit drug use in 33%. Compared with matched controls, all these factors were significantly different. CONCLUSION: Patients with obvious risk factors for assault, such as history of assault, psychosis, and involuntary psychiatric holds, have a substantially greater chance of committing an assault in the healthcare setting. These risk factors can easily be identified and greater security attention given to the patient.

Involuntary Psychiatric Holds in Preadolescent Children.

INTRODUCTION: Little is known about the use of involuntary psychiatric holds in preadolescent children. The primary objective was to characterize patients under the age of 10 years on involuntary psychiatric holds. METHODS: This was a two-year retrospective study from April 2013 - April 2015 in one urban pediatric emergency department (ED). Subjects were all children under the age of 10 years who were on an involuntary psychiatric hold at any point during their ED visit. We collected demographic data including age, gender, ethnicity and details about living situation, child protective services involvement and prior mental health treatment, as well as ED disposition. RESULTS: There were 308 visits by 265 patients in a two-year period. Ninety percent of involuntary psychiatric holds were initiated in the prehospital setting. The following were common characteristics: male (75%), in custody of child protective services (23%), child protective services involvement (42%), and a prior psychiatric hospitalization (32%). Fifty-six percent of visits resulted in discharge from the ED, 42% in transfer to a psychiatric hospital and 1% in admission to the pediatric medical ward. Median length of stay was 4.7 hours for discharged patients and 11.7 hours for patients transferred to psychiatric hospitals. CONCLUSION: To our knowledge, this study presents the first characterization of preadolescent children on involuntary psychiatric holds. Ideally, mental health screening and services could be initiated in children with similar high-risk characteristics before escalation results in placement of an involuntary psychiatric hold. Furthermore, given that many patients were discharged from the ED, the current pattern of utilization of involuntary psychiatric holds in young children should be reconsidered.
