Physician Follow-Up of Pediatric and Young Adult Emergency Department Visits for Substance Use in Ontario, Canada

PurposeTo study the proportion and predictors of outpatient physician follow-up within 60 days of substance-related emergency department (ED) visits for Ontario youth. MethodsWe examined administrative data on substance-related ED visits before and during the COVID-19 pandemic among youths aged 10–24 years in Ontario, Canada. Substance-related visits were identified using International Classification of Diseases-10-CA codes. We described demographic characteristics, receipt of mental health services in the year before the ED visit, disposition from the ED, and follow-up services within 60 days of the ED visit. ResultsBetween April 1, 2017, and May 31, 2021, 64,236 youth had at least one ED visit for substance use. Visits for alcohol were the most common (49%), followed by cannabis (32.3%). ED visits for all substances were more prevalent during the pandemic than prepandemic, except visits for alcohol. The receipt of follow-up physician care for substance use was low (33.2% prepandemic) but increased during the pandemic (41.7%; adjusted odds ratio 1.34, 95% CI 1.28, 1.39) and varied between substances. Mental health service history in the year before the substance-related ED visit had the strongest association with receipt of follow-up physician care within 60 days (adjusted odds ratio 6.86, 95% CI 6.57, 7.17). DiscussionYouth frequently do not receive physician follow-ups within two months of the substance-related ED visit, although higher follow-up proportions were seen during the pandemic after the implementation of virtual care. Further research is required to understand why follow-up is low and to examine interventions that can increase connection to care.

Reduction of Mental Health-Related Emergency Department Admissions for Youth and Young Adults Following a Remote Intensive Outpatient Program: Quality Improvement Analysis.

Pediatric mental health emergency department (ED) visits are increasing at 6% to 10% per year, at substantial cost, while 13% of youth with psychiatric hospitalizations are readmitted in the following weeks. Hospitals do not have the resources to meet escalating youth's mental health needs. Intensive outpatient (IOP) programs, which provide multiple hours of care each week, have the power to reduce the number of patients in need of hospitalized care and provide a step-down option for patients discharging from ED's in order to prevent readmissions. The purpose of this program evaluation was to assess (1) whether youth and young adult ED admission rates decreased following participation in a remote IOP program and (2) whether there were differences in readmission rates between youth and young adults by gender identity, sexual orientation, race, or ethnicity. Data were collected from intake and 3-month postdischarge surveys for 735 clients who attended at least 6 sessions of a remote IOP program for youth and young adults. Patients reported if they had been admitted to an ED within the previous 30 days and the admission reason. Over half (407/707, 57.6%) of clients were adolescents and the rest were young adults (300/707, 42.4%; mean age 18.25, SD 4.94 years). The sample was diverse in gender identity (329/687, 47.9% female; 196/687, 28.5% male; and 65/669, 9.7% nonbinary) and sexual orientation (248/635, 39.1% heterosexual; 137/635, 21.6% bisexual; 80/635, 10.9% pansexual; and 170/635, 26.8% other sexual orientation) and represented several racial (9/481, 1.9% Asian; 48/481, 10% Black; 9/481, 1.9% Indigenous; 380/481, 79% White; and 35/481, 7.2% other) and ethnic identities (112/455, 24.6% Hispanic and 28/455, 6.2% other ethnic identity). Mental health-related ED admissions significantly decreased between intake and 3 months after discharge, such that 94% (65/69) of clients with a recent history of mental health-related ED admissions at IOP intake reported no mental health-related ED admissions at 3 months after discharge from treatment (χ21=38.8, P<.001). There were no differences in ED admissions at intake or in improvement at 3 months after discharge by age, gender, sexuality, race, or ethnicity. This study documents a decrease in ED admissions between intake and 3 months after discharge among both youth and young adults who engage in IOP care following ED visits. The similar outcomes across demographic groups indicate that youth and young adults experience similar decreases after the current tracks of programming. Future research could conduct a full return-on-investment analysis for intensive mental health services for youth and young adults.

Offspring self-disclosure predicts substance-related outcomes in an emergency department sample of young adults with traumatic injury

ABSTRACTBackground: Hundreds of thousands of individuals visit the emergency department (ED) every year, with many visits occurring following alcohol misuse. Parent–child relationship factors are associated with alcohol-related outcomes. For example, offspring choice to self-disclose information about their lives to parents, rather than parents actively soliciting this information, is associated with substance use. However, it is unclear whether self-disclosure uniquely predicts alcohol-related outcomes in a young adult ED sample.Methods: Data were collected from young adults (age 18–30 years) visiting an ED for a traumatic injury (n = 79). Participants were about 24.4 years old, majority male (53.7%), and Caucasian (76%; 24% African-American). A bifactor model within a structural equation model tested unique effects of self-disclosure on age at first drink, propensity for risky drinking, and likelihood of consuming substances prior to ED visit, over and above parental solicitation and a general factor and gender.Results: Those who shared more information with their caregivers reported an older age at first drink, lower propensity for risky drinking and lower propensity to consume substances prior to their ED visit.Conclusions: These findings suggest that self-disclosure may be a unique risk factor in the initiation of alcohol use, development of problem use, and consequences following use.

Impact of healthcare reform on the payer mix among young adult emergency department utilizers across the United States (2005-2015).

Before the patient protection and affordable care act (ACA), young adults (20 to 34) had the highest uninsured rates in the United States (US) and frequently sought care in emergency departments (EDs).We aimed to determine if there was a measurable effect of expanded coverage, specifically the dependent coverage provision and Medicaid expansion, on the payer mix of young adults in EDs.We performed a retrospective cross-sectional study of ED utilization among young adults across the US using the national hospital ambulatory medical care survey (NHAMCS) (2005–2015).We examined the effect of health reform changes on the prevalence and odds of having an insurance type among ED utilizers (19–30) in 3 time periods (2005–2010), (2011–2013), and (2014–2015). Additionally, we compared the national and ED payer mix proportions among 19 to 25 and 26 to 30-year-olds.Our results indicate significant proportional changes in the national and ED payer mix relative to a pre-ACA time period. The 2 greatest changes to the national payer mix were the reduction in the proportion of uninsured/self-payers and the increase in the proportion covered by Medicaid. Furthermore, the dependent coverage provision was effective in increasing the proportion of those (19–25) utilizing private insurance coverage. Lastly, there is now a lower proportion of uninsured young adults in the ED, and an increased proportion of those covered by Medicaid.The change in payer mix among young adults has potential long-term consequences for the provision of emergency department services in the U.S.

Characterization of Young Adult Emergency Department Users: Evidence to Guide Policy

PurposeThe purpose of this study was to characterize young adult patients aged 19–25 years who are emergency department (ED) frequent users and study factors associated with frequent ED use. MethodsED visits among 19- to 25-year olds were identified from administrative records in California, Florida, Iowa, Massachusetts, and New York, 2010. Patients were analyzed for 12 months to study the frequency of their ED utilization. ED visits were categorized according to primary diagnosis. Patients were stratified by frequency of ED use: one visit (single users), two to four visits (infrequent users), and five or more visits (frequent users) in a 1-year period. ResultsWe identified 1,711,774 young adult patients who made 3,650,966 ED visits. Sixty-six percent of patients were single users, 29% were infrequent users, and 4.6% were frequent users. Frequent users accounted for a disproportionate 28.8% of visits within the population studied. Frequent users had the largest proportion of visits for complications of pregnancy (13.6%) compared to single users (6.1%) and Medicaid (42.6%) compared to private insurance (17.3%). There was an increased risk of frequent ED use associated with females (odds ratio [OR]: 1.77), Medicaid (OR: 3.21), and Medicare insurance (OR: 4.22) compared to private insurance, and diseases of the blood (OR: 3.36) and mental illness (OR: 1.99) compared to injury and poisoning. ConclusionsFrequent users comprise a significant portion of the young adult ED population and present with a large proportion of visits for complications of pregnancy. Policies targeting this population might focus on improved access to primary and urgent care, acute obstetric care, and better coordination of care.

Brief Intervention in the Emergency Department Among Mexican-Origin Young Adults at the US-Mexico Border: Outcomes of a Randomized Controlled Clinical Trial Using Promotores.

A randomized controlled trial of brief intervention (BI), for drinking and related problems, using peer health promotion advocates (promotores), was conducted among at-risk and alcohol-dependent Mexican-origin young adult emergency department (ED) patients, aged 18-30. Six hundred and ninety-eight patients were randomized to: screened only (n = 78), assessed (n = 310) and intervention (n = 310). Primary outcomes were at-risk drinking and Rapid Alcohol Problems Screen (RAPS4) scores. Secondary outcomes were drinking days per week, drinks per drinking day, maximum drinks in a day and negative consequences of drinking. At 3- and 12-month follow-up the intervention condition showed significantly lower values or trends on all outcome variables compared to the assessed condition, with the exception of the RAPS4 score; e.g. at-risk drinking days dropped from 2.9 to 1.7 at 3 months for the assessed condition and from 3.2 to 1.2 for the intervention condition. Using random effects modeling controlling for demographics and baseline values, the intervention condition showed significantly greater improvement in all consumption measures at 12 months, but not in the RAPS4 or negative consequences of drinking. Improvements in outcomes were significantly more evident for non-injured patients, those reporting drinking prior to the event, and those lower on risk taking disposition. At 12-month follow-up this study demonstrated significantly improved drinking outcomes for Mexican-origin young adults in the ED who received a BI delivered by promotores compared to those who did not.

A Text Message Alcohol Intervention for Young Adult Emergency Department Patients: A Randomized Clinical Trial

Opportunistic brief in-person emergency department (ED) interventions can be effective at reducing hazardous alcohol use in young adult drinkers, but require resources frequently unavailable. Mobile telephone text messaging (short message service [SMS]) could sustainably deliver behavioral support to young adult patients, but efficacy remains unknown. We report 3-month outcome data of a randomized controlled trial testing a novel SMS-delivered intervention in hazardous-drinking young adults. We randomized 765 young adult ED patients who screened positive for past hazardous alcohol use to one of 3 groups: SMS assessments+feedback (SA+F) intervention who were asked to respond to drinking-related queries and received real-time feedback through SMS each Thursday and Sunday for 12 weeks (n=384), SMS assessments (SA) who were asked to respond to alcohol consumption queries each Sunday but did not receive any feedback (N=196), and a control group who did not participate in any SMS (n=185). Primary outcomes were self-reported number of binge drinking days and number of drinks per drinking day in the past 30 days, collected by Web-based timeline follow-back method and analyzed with regression models. Secondary outcomes were the proportion of participants with weekend binge episodes and most drinks consumed per drinking occasion during 12 weekends, collected by SMS. With Web-based data, there were decreases in the number of self-reported binge drinking days from baseline to 3 months in the SA+F group (-0.51 [95% confidence interval {CI} -0.10 to -0.95]), whereas there were increases in the SA group (0.90 [95% CI 0.23 to 1.6]) and the control group (0.41 [95% CI -0.20 to 1.0]). There were also decreases in the number of self-reported drinks per drinking day from baseline to 3 months in the SA+F group (-0.31 [95% CI -0.07 to -0.55]), whereas there were increases in the SA group (0.10 [95% CI -0.27 to 0.47]) and the control group (0.39 [95% CI 0.06 to 0.72]). With SMS data, there was a lower mean proportion of SA+F participants reporting a weekend binge during 12 weeks (30.5% [95% CI 25% to 36%) compared with the SA participants (47.7% [95% CI 40% to 56%]). There was also a lower mean drinks consumed per weekend during 12 weeks in the SA+F group (3.2 [95% CI 2.6 to 3.7]) compared to the SA group (4.8 [95% CI 4.0 to 5.6]). A text message intervention can produce small reductions in self-reported binge drinking and the number of drinks consumed per drinking day in hazardous-drinking young adults after ED discharge.

Energy Drink and Other Substance Use Among Adolescent and Young Adult Emergency Department Patients

This study aimed to understand current patterns of energy drink use and compare the extent of usage of energy drinks and other commonly used and misused substances between adolescent (13-17-years-old) and young adult (18-25-years-old) emergency department (ED) patients. During a 6-week period between June and August 2010, all patients presenting to an adult or pediatric ED were asked to complete a computer-based, anonymous questionnaire regarding use of energy drinks and other substances. Wilcoxon rank-sum, 2-sample tests of binomial proportions, Pearson χ(2) testing, and regression models were used to compare energy drink and substance use by age groups. Past 30-day energy drink use was greater for young adults (57.9%) than adolescents (34.9%) (P < 0.03). Adolescents typically consumed a mean of 1.5 and young adults a mean of 2.6 energy drinks per day when using energy drinks and drank at most a mean of 2.4 and 2.6 drinks per day, respectively. Among adolescents, energy drink usage was more common than alcohol, "street" or illicit drugs, and tobacco usage, but less common than caffeine product usage. For young adults, energy drink usage was more common than "street" or illicit drugs, but less common than caffeine use, and similar to tobacco and alcohol usage. Young adult energy drink users were more likely than young adult non-energy drink users also to use tobacco and caffeine. Energy drink use is common among ED patients. Given the high prevalence of energy drink use observed, emergency physicians should consider the involvement of energy drinks in the presentations of young people.

When Coverage Expands: Children's Health Insurance Program as a Natural Experiment in Use of Health Care Services

Expanding insurance coverage is designed to improve access to primary care and reduce use of emergency department (ED) services. Whether expanding coverage achieves this is of paramount importance as the United States prepares for the Affordable Care Act. Emergency and outpatient department use was examined after the State Children's Health Insurance Program (CHIP) coverage expansion, focusing on adolescents (a major target group for CHIP) versus young adults (not targeted). The hypothesis was that coverage would increase use of outpatient services, and ED use would decrease. Using the National Ambulatory Medical Care Survey (NAMCS) and the National Hospital Ambulatory Medical Care Survey (NHAMCS), theyears 1992-1996 were analyzed as baseline and then compared to use patterns in 1999-2009, after the CHIP launch. Primary outcomes were population-adjusted annual visits to ED versus nonemergency outpatient settings. Interrupted time series were performed on use rates to ED and outpatient departments between adolescents (11 to 18years old) and young adults (19 to 29years old) in the pre-CHIP and CHIP periods. Outpatient-to-ED ratios were calculated and compared across time periods. A stratified analysis by payer and sex was also performed. The mean number of outpatient adolescent visits increased by 299 visits per 1,000 persons (95% confidence interval [CI]=140 to 457), while there was no statistically significant increase in young adult outpatient visits across time periods. There was no statistically significant change in the mean number of adolescent ED visits across time periods, while young adult ED use increased by 48 visits per 1,000 persons (95% CI=24 to 73). The adolescent outpatient-to-ED ratio increased by 1.0 (95% CI=0.49 to 1.6), while the young adults ratio decreased by 0.53 across time periods (95% CI=-0.90 to -0.16). Since CHIP, adolescent non-ED outpatient visits have increased, while ED visits have remained unchanged. In comparison to young adults, expanding insurance coverage to adolescents improved use of health care services and suggests a shift to non-ED settings. Expanding insurance through the Affordable Care Act of 2010 will likely increase use of outpatient services, but may not decrease ED volumes.

Behavioral and physiologic adverse effects in adolescent and young adult emergency department patients reporting use of energy drinks and caffeine

Introduction. This pilot study assessed the prevalence of physiologic and behavioral adverse effects among adolescent (13–17 years) and adult (18–25 years) emergency department patients who reported energy drink and/or caffeinated-only beverage use within the 30 days prior to emergency department presentation. It was hypothesized that energy drink users would report more adverse effects than those who used only traditional caffeinated beverages such as coffee, tea, or soft drinks. Methods. This cross-sectional pilot study was conducted in two urban emergency departments, one adult and one pediatric. Eligible patients were enrolled during a 6-week period between June and August 2010. Participants completed a tablet computer-based, self-administered, anonymous questionnaire about their past 30-day energy drink and/or caffeinated-only beverage use, substance use, and experience of 10 physiologic and 10 behavioral symptoms. Multivariable logistic regression and negative binomial regression models, adjusted for age, gender, and substance use, were created to compare the occurrence of each adverse effect between energy drink and caffeinated-only beverage users. Odds ratios (ORs) and incidence rate ratios (IRRs) were estimated. Results. Of those enrolled, 53.3% reported consuming energy drinks, 39.1% caffeinated-only beverages, and 7.6% no energy drinks or caffeinated-only beverages within the past 30 days. In multivariable logistic regression models, energy drink users were more likely than caffeinated-only beverage users to report having “gotten into trouble at home, school, or work” in the past 30 days (OR: 3.12 [1.24–7.88]). In the negative binomial regression multivariable models, more behavioral effects were reported among drug users (IRR: 1.50 [1.18–1.93]), and more physiologic effects were reported among tobacco users (IRR: 1.42 [1.13–1.80]) and females (IRR: 1.48 [1.21–1.80]), but not among energy drink users. Conclusions. Energy drink users and substance users are more likely to report specific physiologic and behavioral adverse effects. Emergency department clinicians should consider asking patients about energy drink and traditional caffeine usage and substance use when assessing patient symptoms.

Unsuspected or Unacknowledged Depressive Symptoms in Young Adult Emergency Department Patients

The objective was to determine the frequency of unsuspected or unacknowledged depressive symptoms among young adult emergency department (ED) patients. The Beck Depression Inventory-II (BDI-II) and a demographic/lifestyle questionnaire were administered to a cross-section of medically stable, English-speaking young adult ED patients (aged 18-23 years) with nonpsychiatric chief complaints. The frequency of moderate to severe depressive symptoms was determined. Group results were analyzed with descriptive statistics; multivariate analysis assessed for patient characteristics associated with depressive symptoms. A total of 2,898 patients were screened; 2,255 were eligible for enrollment, and 1,264 enrolled (56%; 64% female, 42% African American; mean age = 21 [+/-1.7] years). Twenty-nine percent had BDI-II scores consistent with moderate to severe depressive symptoms. Patient characteristics associated with depressive symptoms included knowledge of someone who had intentionally hurt him- or herself (odds ratio [OR] = 2) or died a violent nonaccidental death (OR = 1.4), low personal income (OR = 1.8), chronic health issues (OR = 1.7), cigarette smoking (OR = 1.6), and African American race (OR = 1.5). Those who attended school (OR = 0.5), engaged in frequent social activities (OR = 0.5), or drove a car (OR = 0.7) were less likely to have depressive symptoms. Patients lacked insight into their depressive symptoms. There is a high prevalence of depressive symptoms in young adult ED patients. Young adults often do not recognize, or are reluctant to acknowledge, depressive symptoms. Specific patient characteristics may be useful in deciding which young adults should undergo ED screening for depression.

Readiness to change problematic drinking assessed in the emergency department as a predictor of change

Objectives The goal of this study was to determine if baseline readiness to change the drinking behavior (precontemplation, contemplation, preparation, and action stages) was predictive of change in drinking after unrelated emergency department (ED) visit and screening and interviewing for alcohol problems. Methods From August 1998 through December 2000, the Alcohol Use Disorders Identification Test (AUDIT) was administered to all consented ED patients aged 18 to 29 years. A brief motivational interviewing was provided to screen-positive patients (AUDIT score >5 of 40). Outcome at 3-month follow-up was measured as a decrease in the scores within the AUDIT domains of alcohol intake, harm, and dependency. Results Sixty percent of the screen-positive patients continued to drink at 3 months. Patients became more open to change their drinking behavior. Compared with patients in the precontemplation stage, those in the action stage were twice as likely to reduce their alcohol intake (OR, 2.24; 95% CI, 1.06-4.72), nearly 3 times as likely to reduce their alcohol-related harm behavior (OR, 2.80; 95% CI, 1.59-4.91), and almost 4 times more likely to decrease their dependency symptoms (OR, 3.59; 95% CI, 1.97-6.57). Compared with precontemplation patients, those in the contemplation stage were nearly twice as likely to reduce their alcohol-related harm (OR, 1.85; 95% CI, 1.02-3.33) and those in the preparation stage were more than twice as likely to reduce their dependency symptoms (OR, 2.20, 95% CI, 1.13-4.27). Conclusions Stages of change at baseline appeared to be significant predictors of change in alcohol intake, harm, and dependency symptoms among young adult ED patients.

Alcohol problems among young adult emergency department patients: Making predictions using routine sociodemographic information

The study aims were to explore the process of identifying young adult Emergency Department (ED) patients at risk for alcohol problems, examine the sociodemographic predictors of patient alcohol problems, and determine differences between patients who screened positive and those who screened negative for alcohol problems. Implications for ED practice are discussed. As part of a larger study, the Alcohol Use Disorders Identification Test was administered to consenting patients ages 18 to 29. A score of greater than 5 (out of 40) was considered a positive screen for alcohol problems. Sociodemographic information was collected from a generic Individual Information Form. Approximately 48% (1855 of 3890) of patients screened positive for alcohol problems. Among screen-positive patients, 91% (1689) had scores that corresponded to mild to moderate alcohol problems. Compared with screen-negative patients, screen-positive patients were almost 3 times more likely to be men (odds ratio [OR] = 2.70); 2.5 times more likely to use tobacco (OR = 2.43); 2 times more likely to be single (OR = 2.03); and 1.5 times more likely to have some college education (OR = 1.41), be an 18- to 20-year-old adult (OR = 1.61), be a college student (OR = 1.60), be unemployed (OR = 1.39), and cohabitate with friends (OR = 1.19). Screen-positive patients also were more likely to have made at least one past attempt to change their drinking behavior (OR = 3.21). Routine patient information presented an accurate risk profile for alcohol problems among patients in this study. If ED-based health care professionals routinely screened patients for alcohol problems or could predict potential alcohol problems by using routinely collected information, then intervention or referral for additional services may increase.

Conjoint smoking and drinking: a case for dual-substance intervention among young emergency department patients.

To better understand conjoint smoking and drinking among young adult emergency department (ED) patients, the purposes of this investigation were: 1) to assess the prevalence of conjoint use; 2) to determine the factors associated with conjoint alcohol use and smoking; and 3) to address the implications for future ED-based investigation of dual-substance intervention. Data for this investigation were obtained from a battery of questionnaires administered to the routine-care patients during an alcohol screening in the ED, which was part of a larger alcohol intervention study. Study findings revealed that a majority of patients with self-reported alcohol-related problems were smokers. In fact, drinkers who smoked were likely to be pack-a-day smokers. Among the study sample, being female, having low education levels (e.g., high school education or less), having some emotional problems, and currently using marijuana were risk factors for conjoint smoking and drinking. Conjoint users were identifiable through brief screening. Given the prevalence of conjoint smoking and alcohol use among the ED sample and a specific set of risk factors, tailored intervention for alcohol and nicotine dependence may be an important and opportunistic clinical ED service.
