Further Utilization of Emergency Department and Inpatient Psychiatric Services Among Young Adults Admitted at the Emergency Department With Clinical Alcohol Intoxication

Acute care utilization and its associated determinants among patients with substance-related disorders: A worldwide systematic review and meta-analysis

INTRODUCTION

Identifying determinants of emergency department (ED) use and hospitalization among patients with substance-related disorders (SRDs) can improve health services to address unmet health needs.

AIM

The present study aimed to identify the prevalence rates of ED use and hospitalization, and their associated determinants among patients with SRDs.

METHODS

Studies in English published from January 1, 1995, to December 1, 2022, were searched on PubMed, Scopus, Cochrane Library, and Web of Science to identify primary studies.

RESULTS

The pooled prevalence rates of ED use and hospitalization among patients with SRDs were 36% and 41%, respectively. Patients with SRDs who were the most at risk of being both ED users and hospitalized were those (i) having medical insurance, (ii) having other drug and alcohol use disorders, (iii) having mental health disorders, and (iv) having chronic physical illnesses. A lower level of education increased the risk of ED use only.

DISCUSSION

To decrease ED use and hospitalization, more comprehensive services may be offered to these vulnerable patients with diversified needs.

IMPLICATIONS FOR PRACTICE

Chronic care integrating outreach interventions could be more provided for patients with SRDs after discharge from acute care units or hospitals.

Who benefits from brief motivational intervention among young adults presenting to the emergency department with alcohol intoxication: A latent-class moderation analysis

BACKGROUND

Research has not identified which patients optimally benefit from brief Motivational Interviewing (bMI) for heavy drinking when delivered to young adults in the Emergency Department (ED).

METHODS

We conducted secondary analyses of data from a randomized controlled trial in which 344 young adults (18-35 years) presenting to the ED with alcohol intoxication received either bMI or Brief Advice (BA, control group). We used Latent Class Analysis to derive participants' profiles from baseline characteristics (i.e., sex, age, severity of alcohol use disorder, attribution of ED admission to alcohol use, importance, and confidence to change, cognitive discrepancy, anxiety, depression, and trait reactance). We then conducted a moderation analysis to assess the number of heavy drinking days at short-term (1-month) and long-term (12-month) follow-up using negative binomial regressions with interactions between the intervention and derived classes.

RESULTS

Fit statistics indicated that a 4-class solution best fit the data. Class 3 (high severity, importance and discrepancy, and low confidence and anxiety) benefitted more from bMI than BA at short- and long-term follow-up than Class 1 (younger; lowest severity, importance, discrepancy, reactance, anxiety and depression, and highest confidence). Class 2 (older; highest severity, importance, discrepancy, reactance, anxiety and depression, and lowest confidence) also benefitted more from bMI than BA than did Class 1 at short-term follow-up. In these significant contrasts, Class 1 benefitted more from BA than bMI. There were no significant interactions involving Class 4 (more likely to be women; low severity; high levels of anxiety, depression, and reactance).

CONCLUSIONS

This study identified the patient profiles that benefitted more from bMI than BA among nontreatment-seeking young adults who present intoxicated to the ED. The findings have implications for intervention design and argue for the importance of research aimed at developing intervention content tailored to patient profiles.

Emergency Department Use, Hospitalization, and Their Sociodemographic Determinants among Patients with Substance-Related Disorders: A Worldwide Systematic Review and Meta-Analysis

Background: Identifying the determinants of emergency department (ED) use and hospitalization among patients with substance-related disorders (SRD) can help inform healthcare services and case management regarding their unmet health needs and strategies to reduce their acute care. Objectives: The present study aimed to identify sociodemographic characteristics, type of used drug, and risky behaviors associated with ED use and hospitalization among patients with SRD. Methods: Studies in English published from January 1st, 1995 to April 30th, 2022 were searched from PubMed, Scopus, Cochrane Library, and Web of Science to identify primary studies on ED use and hospitalization among patients with SRD. Results: Of the 17,348 outputs found, a total of 39 studies met the eligibility criteria. Higher ED use and hospitalization among patients with SRD were associated with a history of homelessness (ED use: OR = 1.93, 95%CI = 1.32-2.83; hospitalization: OR = 1.53, 95%CI = 1.36-1.73) or of injection drug use (ED use: OR = 1.34, 95%CI = 1.13-1.59; hospitalization: OR = 1.42, 95%CI = 1.20-1.69). Being female (OR = 1.24, 95%CI = 1.14-1.35), using methamphetamine (OR = 1.99, 95%CI = 1.24-3.21) and tobacco (OR = 1.25, 95%CI = 1.11-1.42), having HIV (OR = 1.70, 95%CI = 1.47-1.96), a history of incarceration (OR = 1.90, 95%CI = 1.27-2.85) and injury (OR = 2.62, 95%CI = 1.08-6.35) increased ED use only, while having age over 30  years (OR = 1.40, 95%CI = 1.08-1.81) and using cocaine (OR = 1.60, 95%CI = 1.32-1.95) increased hospitalization only among patients with SRD. Conclusions: The finding outline the necessity of developing outreach program and primary care referral for patients with SRD. Establishing a harm reduction program, incorporating needle/syringe exchange programs, and safe injection training with the aim of declining ED use and hospitalization, is likely be another beneficial strategy for patients with SRD.

Effect of a Novel Brief Motivational Intervention for Alcohol-Intoxicated Young Adults in the Emergency Department: A Randomized Clinical Trial

IMPORTANCE

Heavy drinking among young adults is a major public health concern. Brief motivational interventions in the emergency department have shown promising but inconsistent results.

OBJECTIVE

To test whether young adults receiving a newly developed brief motivational intervention reduce their number of heavy drinking days and alcohol-related problems over 1 year compared with participants receiving brief advice.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial was conducted at an emergency department of a tertiary care university hospital in Lausanne, Switzerland. Recruitment ran from December 2016 to August 2019. Follow-up was conducted after 1, 3, 6, and 12 months. All adults aged 18 to 35 years presenting for any cause and presenting with alcohol intoxication were eligible (N = 2108); 1764 were excluded or refused participation. Follow-up rate was 79% at 12 months and 89% of participants provided follow-up data at least once and were included in the primary analyses. Statistical analysis was performed from September 2020 to January 2021.

INTERVENTIONS

The novel intervention was based on motivational interviewing and comprised in-person discussion in the emergency department and up to 3 booster telephone calls. The control group received brief advice.

MAIN OUTCOMES AND MEASURES

Primary outcomes were the number of heavy drinking days (at least 60 g of ethanol) over the previous month and the total score on the Short Inventory of Problems (0-45, higher scores indicating more problems) over the previous 3 months. Hypotheses tested were formulated before data collection.

RESULTS

There were 344 young adults included (median [IQR] age: 23 [20-28] years; 84 women [24.4%]). Among the 306 participants providing at least 1 follow-up point, a statistically significant time × group interaction was observed (β = -0.03; 95% CI, -0.05 to 0.00; P = .02), and simple slopes indicated an increase of heavy drinking days over time in the control (β = 0.04; 95% CI, 0.02 to 0.05; P < .001) but not in the intervention group (β = 0.01; 95% CI, -0.01 to 0.03; P = .24). There was no effect on the Short Inventory of Problems score (β = -0.01; 95% CI, -0.03 to 0.02; P = .71).

CONCLUSIONS AND RELEVANCE

This randomized clinical trial found that a brief motivational intervention implemented in the emergency department provided beneficial effects on heavy drinking, which accounts for a substantial portion of mortality and disease burden among young adults.

Frequencies of emergency department use and hospitalization comparing patients with different types of substance or polysubstance-related disorders

Background

This study measured emergency department (ED) use and hospitalization for medical reasons among patients with substance-related disorders (SRD), comparing four subgroups: cannabis-related disorders, drug-related disorders other than cannabis, alcohol-related disorders and polysubstance-related disorders, controlling for various clinical, sociodemographic and service use variables.

Methods

Clinical administrative data for a cohort of 22,484 patients registered in Quebec (Canada) addiction treatment centers in 2012-13 were extracted for the years 2009-10 to 2015-16. Using negative binomial models, risks of frequent ED use and hospitalization were calculated for a 12-month period (2015-16).

Results

Patients with polysubstance-related disorders used ED more frequently than other groups with SRD. They were hospitalized more frequently than patients with cannabis or other drug-related disorders, but less frequently than those with alcohol-related disorders. Patients with alcohol-related disorders used ED more frequently than those with cannabis-related disorders and underwent more hospitalizations than both patients with cannabis-related and other drug-related disorders. Co-occurring SRD-mental disorders or SRD-chronic physical illnesses, more years with SRD, being women, living in rural territories, more frequent consultations with usual general practitioner or outpatient psychiatrist, and receiving more interventions in community healthcare centers increased frequency of ED use and hospitalization, whereas both adverse outcomes decreased with high continuity of physician care. Behavioral addiction, age less than 45 years, living in more materially deprived areas, and receiving 1-3 interventions in addiction treatment centers increased risk of frequent ED use, whereas living in semi-urban areas decreased ED use. Patients 25-44 years old receiving 4+ interventions in addiction treatment centers experienced less frequent hospitalization.

Conclusion

Findings showed higher risk of ED use among patients with polysubstance-related disorders, and higher hospitalization risk among patients with alcohol-related disorders, compared with patients affected by cannabis and other drug-related disorders. However, other variables contributed substantially more to the frequency of ED use and hospitalization, particularly clinical variables regarding complexity and severity of health conditions, followed by service use variables. Another important finding was that high continuity of physician care helped decrease the use of acute care services. Strategies like integrated care and outreach interventions may enhance SRD services.
