Exploring the components of an efficacious computer brief intervention for reducing marijuana use among adults in the emergency department.

ABSTRACT:

Objective

To examine the efficacious components of a computer-delivered brief intervention (CBI) for reducing marijuana use among adults presenting to a low-income urban emergency department (ED), which a prior report found to decrease marijuana use at a 6-month follow-up.

Method

Participants were 237 ED patients reporting recent drug use (46% male; 54% African-American; mean age, 30.7) who were randomized to receive a CBI consisting of an interactive program guided by a virtual health counselor. The primary outcome was past 30-day marijuana use at 6-month follow-up assessed using the Timeline Follow-Back (TLFB). Intervention components related to change in marijuana use at 6 month follow-up examined in the current study included participant responses to items within five CBI domains that were rooted in motivational interviewing: goals for change, strengths, evoking-change (concerns about use and benefits of change), challenges, and tools for change.

Results

The evoking-change domain was related to significant reductions in marijuana use at 6 months (B = -2.91, SE = 1.10, p < .01). Within this domain, items focused on concerns about family and friends were related to reductions in marijuana use of up to 5.5 fewer days of marijuana use in the past month (B = -5.49, SE = 1.63, p < .01).

Conclusions

An ED-based brief intervention, delivered by computer, was effective in reducing marijuana use. Intervention components focused on perceived concerns about use and benefits of change in relation to family and friends were critical domains within a CBI associated with reductions in marijuana use at 6-month follow-up.

Project description:Study objectiveBrief interventions have been shown to reduce alcohol use and improve outcomes in hazardous and harmful drinkers, but evidence to support their use in emergency department (ED) patients is limited. The use of research assessments in studies of brief interventions may contribute to uncertainty about their effectiveness. Therefore we seek to determine (1) if an emergency practitioner-performed Brief Negotiation Interview or a Brief Negotiation Interview with a booster reduces alcohol consumption compared with standard care; and (2) the impact of research assessments on drinking outcomes using a standard care-no-assessment group.MethodsWe randomized 889 adult ED patients with hazardous and harmful drinking. A total of 740 received an emergency practitioner-performed Brief Negotiation Interview (n=297), a Brief Negotiation Interview with a 1-month follow-up telephone booster (Brief Negotiation Interview with booster) (n=295), or standard care (n=148). We also included a standard care with no assessments (n=149) group to examine the effect of assessments on drinking outcomes. Primary outcomes analyzed with mixed-models procedures included past 7-day alcohol consumption and 28-day binge episodes at 6 and 12 months, collected by interactive voice response. Secondary outcomes included negative health behaviors and consequences collected by telephone surveys.ResultsThe reduction in mean number of drinks in the past 7 days from baseline to 6 and 12 months was significantly greater in the Brief Negotiation Interview with booster (from 20.4 [95% confidence interval {CI} 18.8 to 22.0] to 11.6 [95% CI 9.7 to 13.5] to 13.0 [95% CI 10.5 to 15.5]) and Brief Negotiation Interview (from 19.8 [95% CI 18.3 to 21.4] to 12.7 [95% CI 10.8 to 14.6] to 14.3 [95% CI 11.9 to 16.8]) than in standard care (from 20.9 [95% CI 18.7 to 23.2] to 14.2 [95% CI 11.2 to 17.1] to 17.6 [95% CI 14.1 to 21.2]). The reduction in 28-day binge episodes was also greater in the Brief Negotiation Interview with booster (from 7.5 [95% CI 6.8 to 8.2] to 4.4 [95% CI 3.6 to 5.2] to 4.7 [95% CI 3.9 to 5.6]) and Brief Negotiation Interview (from 7.2 [95% CI 6.5 to 7.9] to 4.8 [95% CI 4.0 to 5.6] to 5.1 [95% CI 4.2 to 5.9]) than in standard care (from 7.2 [95% CI 6.2 to 8.2] to 5.7 [95% CI 4.5 to 6.9] to 5.8 [95% CI 4.6 to 7.0]). The Brief Negotiation Interview with booster offered no significant benefit over the Brief Negotiation Interview alone. There were no differences in drinking outcomes between the standard care and standard care-no assessment groups. The reductions in rates of driving after drinking more than 3 drinks from baseline to 12 months were greater in the Brief Negotiation Interview (38% to 29%) and Brief Negotiation Interview with booster (39% to 31%) groups than in the standard care group (43% to 42%).ConclusionEmergency practitioner-performed brief interventions can reduce alcohol consumption and episodes of driving after drinking in hazardous and harmful drinkers. These results support the use of brief interventions in ED settings.

Project description:IntroductionThe opioid epidemic is a major cause of morbidity and mortality in the United States. Prior work has shown that emergency department (ED) opioid prescribing can increase the incidence of opioid use disorder in a dose-dependent manner, and systemic changes that decrease default quantity of discharge opioid tablets in the electronic health record (EHR) can impact prescribing practices. However, ED leadership may be interested in the impact of communication around the intervention as well as whether the intervention may differentially impact different types of clinicians (physicians, physician assistants [PA], and nurse practitioners). We implemented and evaluated a quality improvement intervention of an announced decrease in EHR default quantities of commonly prescribed opioids at a large, academic, urban, tertiary-care ED.MethodsWe gathered EHR data on all ED discharges with opioid prescriptions from January 1, 2019-December 6, 2021, including chief complaint, clinician, and opioid prescription details. Data was captured and analyzed on a monthly basis throughout this time period. On March 29, 2021, we implemented an announced decrease in EHR default dispense quantities from 20 tablets to 12 tablets for commonly prescribed opioids. We measured pre- and post-intervention quantities of opioid tablets prescribed per discharge receiving opioids, distribution by patient demographics, and inter-clinician variability in prescribing behavior.ResultsThe EHR change was associated with a 14% decrease in quantity of opioid tablets per discharge receiving opioids, from 14 to 12 tablets (P = <.001). We found no statistically significant disparities in prescriptions based on self-reported patient race (P = 0.68) or gender (P = 0.65). Nurse practitioners and PAs prescribed more opioids per encounter than physicians on average and had a statistically significant decrease in opioid prescriptions associated with the EHR change. Physicians had a lesser but still significant drop in opioid prescribing in the post-intervention period.ConclusionDecreasing EHR defaults is a robust, simple tool for decreasing opioid prescriptions, with potential for implementation in the 42% of EDs nationwide that have defaults exceeding the recommended 12-tablet supply. Considering significant inter-clinician variability, future interventions to decrease opioid prescriptions should examine the effects of combining EHR default changes with targeted interventions for clinician groups or individual clinicians.

Project description:BackgroundViolent injury is the leading cause of death among urban youth. Emergency department (ED) visits represent an opportunity to deliver a brief intervention (BI) to reduce violence among youth seeking medical care in high-risk communities.ObjectiveThe objective was to determine the efficacy of a universally applied BI addressing violence behaviors among youth presenting to an urban ED.MethodsED youth (14 to 20 years old) seeking medical or injury-related care in a Level I ED (October 2011-March 2015) and screening positive for a home address within the intervention or comparison neighborhood of a larger youth violence project were enrolled in this quasi-experimental study. Based on home address, participants were assigned to receive either the 30-minute therapist-delivered BI (Project Sync) or a resource brochure (enhanced usual care [EUC] condition). The Project Sync BI combined motivational interviewing and cognitive skills training, including a review of participant goals, tailored feedback, decisional balance exercises, role-playing exercises, and linkage to community resources. Participants completed validated survey measures at baseline and a 2-month follow-up assessment. Main outcome measures included self-report of physical victimization, aggression, and self-efficacy to avoid fighting. Poisson and zero-inflated Poisson regression analyses analyzed the effects of the BI, compared to the EUC condition, on primary outcomes.ResultsA total of 409 eligible youth (82% participation) were enrolled and assigned to receive either the BI (n = 263) or the EUC condition (n = 146). Two-month follow-up was 91% (n = 373). There were no significant baseline differences between study conditions. Among the entire sample, mean (±SD) age was 17.7 (±1.9) years, 60% were female, 93% were African American, and 79% reported receipt of public assistance. Of participants, 9% presented for a violent injury, 9% reported recent firearm carriage, 20% reported recent alcohol use, and 39% reported recent marijuana use. Compared with the EUC group, participants in the therapist BI group showed self-reported reductions in frequency of violent aggression (therapist, -46.8%; EUC, -36.9%; incident rate ratio [IRR] = 0.87; 95% confidence interval [CI] = 0.76 to 0.99) and increased self-efficacy for avoiding fighting (therapist, +7.2%; EUC, -1.3%; IRR = 1.09; 95% CI = 1.02 to 1.15). No significant changes were noted for victimization.ConclusionsAmong youth seeking ED care in a high-risk community, a brief, universally applied BI shows promise in increased self-efficacy for avoiding fighting and a decrease in the frequency of violent aggression.

Project description:ObjectiveTo identify multivariable subgroups of patients with differential responses to a nurse-delivered care transition intervention after an emergency department (ED) visit in a randomized controlled trial (RCT) using an emerging data-driven method.DesignSecondary analysis of RCT.Participants512 individuals enrolled in an RCT of a nurse-delivered care transition intervention after an ED visit. All 512 participants were included in a pre-specified subgroup analysis, and 451 of these had sufficient complete case data to be included in a model-based recursive (MoB) partitioning analysis.MethodsThe primary outcome was having at least one ED visit in 30 days after the index ED visit. Two analytical methods explored heterogeneity of treatment effects: data driven model-based recursive partitioning (MoB) using 37 candidate baseline variables, and a contextual point of comparison with prespecified subgroups defined by ED super-user status (≥ 3 ED visits in previous 6 months or not), sex (male/female), and age, individually examined via treatment arm by subgroup interaction terms in logistic regression models. Internal validation of the MoB analysis via bootstrap resampling with an optimism corrected c-statistic was conducted to provide a bias-corrected estimate.ResultsMoB detected treatment effect heterogeneity in a single subgroup, marital status. Unmarried patients randomized to the intervention had a repeat ED use rate of 22% compared to 34% in the usual care group; married patients randomized to the intervention had a 27% ED return rate compared to 12% in the usual care group. Internal validation demonstrated an optimism corrected c-statistic of 0.54. No treatment-by-covariate subgroup interactions were identified among the 3 prespecified subgroups.ConclusionAlthough exploratory, the results of the MoB analysis suggest that patient factors related to social relationships such as marital status may be important contributors to differential response to a care transition intervention after an ED visit. These were characteristics that the investigators had not anticipated or planned to examine in the individual prespecified subgroup analysis. Data-driven methods can yield unexpected findings and contribute to a more complete understanding of differential treatment effects in subgroup analysis, which can inform further work on development of effective care transition interventions in the ED setting.

Project description:Most previous brief intervention (BI) studies have focused on alcohol or drug use, instead of both substances. Our primary aim was to determine if an alcohol- and drug-use BI reduced alcohol use and increased alcohol treatment services utilization among adult emergency department (ED) patients who drink alcohol and require an intervention for their drug use. Our secondary aims were to assess when the greatest relative reductions in alcohol use occurred, and which patients (stratified by need for an alcohol use intervention) reduced their alcohol use the most. In this secondary analysis, we studied a sub-sample of participants from the Brief Intervention for Drug Misuse in the Emergency Department (BIDMED) randomized, controlled trial of a BI vs. no BI, whose responses to the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) indicated a need for a BI for any drug use, and who also reported alcohol use. Participants were stratified by their ASSIST alcohol subscore: 1) no BI needed, 2) a BI needed, or 3) an intensive intervention needed for alcohol use. Alcohol use and alcohol treatment services utilization were measured every 3 months for 12 months post-enrollment. Of these 833 participants, median age was 29 years-old, 46% were female; 55% were white/non-Hispanic, 27% black/non-Hispanic, and 15% Hispanic. Although any alcohol use, alcohol use frequency, days of alcohol use, typical drinks consumed/day, and most drinks consumed/day decreased in both the BI and no BI arms, there were no differences between study arms. Few patients sought alcohol use treatment services in follow-up, and utilization also did not differ by study arm. Compared to baseline, alcohol use reduced the most during the first 3 months after enrollment, yet reduced little afterward. Participants whose ASSIST alcohol subscores indicated a need for an intensive intervention generally had the greatest relative decreases in alcohol use. These results indicate that the BI was not efficacious in reducing alcohol use among alcohol- and drug-using adult ED patients than the self-assessments alone, but suggest that self-assessments with or without a BI may confer reductions in alcohol use.
