Implementations of a text-message intervention to increase linkage from the emergency department to outpatient treatment for substance use disorders

An Automated Text Messaging Intervention to Reduce Substance Use Self-Stigma (Project RESTART): Protocol for a Feasibility and Acceptability Pilot Study

BACKGROUND

Stigma is a barrier to treatment and harm reduction seeking in people who use drugs. Most stigma reduction interventions offer psychotherapy or psychoeducation in group-based clinical settings, failing to reach people who are not in treatment. SMS text messaging is an effective and acceptable modality for delivering health information to people who use drugs and may be a suitable conduit for providing information and advice to understand and cope with stigma.

OBJECTIVE

This paper presents the protocol for a study that aims to determine the feasibility, acceptability, and preliminary effectiveness of a 4-week automated SMS text message intervention to increase stigma resistance and reduce self-stigma in people who use drugs.

METHODS

We designed a novel automated SMS text message intervention to address the four personal-level constructs of stigma resistance: (1) not believing stigma and catching and challenging stigmatizing thoughts, (2) empowering oneself through learning about substance use and one's recovery, (3) maintaining one's recovery and proving stigma wrong, and (4) developing a meaningful identity and purpose apart from one's substance use. Theory-based messages were developed and pilot-tested in qualitative elicitation interviews with 22 people who use drugs, resulting in a library of 56 messages. In a single-group, within-subjects, community-based pilot trial, we will enroll 30 participants in the Resisting Stigma and Revaluating Your Thoughts (RESTART) intervention. Participants will receive 2 daily SMS text messages for 4 weeks. Implementation feasibility will be assessed through recruitment, enrollment, retention, and message delivery statistics. User feasibility and acceptability will be assessed at follow-up using 23 survey items informed by the Theoretical Framework of Acceptability. Primary effectiveness outcomes are changes in self-stigma (Substance Abuse Self-Stigma Scale) and stigma resistance (Stigma Resistance Scale) from baseline to follow-up measured via a self-administered survey. Secondary outcomes are changes in hope (Adult Dispositional Hope Scale) and self-esteem (Rosenberg Self-Esteem Scale). Feasibility and acceptability will be assessed with descriptive statistics; effectiveness outcomes will be assessed with paired 2-tailed t tests, and group differences will be explored using ANOVA. Overall, 12 participants will also be selected to complete acceptability interviews.

RESULTS

This pilot study was funded by the National Institute on Drug Abuse in April 2023 and received regulatory approval in January 2024 by the University of North Carolina-Chapel Hill Institutional Review Board. Recruitment and enrollment began in March 2024. Follow-up visits are expected to conclude by May 2024. Results will be disseminated in relevant peer-reviewed journals.

CONCLUSIONS

To the best of our knowledge, this is the first study to address substance use stigma via a self-help SMS text messaging program. Results will add to the nascent literature on stigma reduction in people who use drugs. This protocol may interest researchers who are considering text messaging to address psychosocial needs in hard-to-reach populations.

Implementing a Screening Tool and Referral Process for Substance Use Disorders in the Emergency Department: A Quality Improvement Project

INTRODUCTION

Substance misuse in the United States has continuously proven to be a public health issue. The impact of substance use disorder and the injury and illness it produces creates challenges in the public health sector. This quality improvement project aimed to increase screening and referral rates in a rural emergency department.

METHODS

The CAGE-AID screening tool was implemented into the triage process in the Meditech Expanse system; 1077 patients were included in this quality improvement project. This initiative used Plan-Do-Study-Act cycles, collecting data weekly.

RESULTS

There were 1077 patients available for the new screening process. This included 468 males (43.5%) and 609 females (56.5%). Of the 1077 patients, all (100%) were screened with the leading question. All patients (100%) were subsequently screened with the 4-item CAGE-AID tool if they answered "yes" to the leading question. Of these patients, 962 screened negative (89.3%) and 115 screened positive (10.7%). For those 115 positive screens, 63 denied referrals (54.8%) and 52 (45.2%) accepted referral. Of those 52 who accepted referral, 9 (17.3%) scheduled themselves for a follow-up appointment within 30 days of the new process going live.

CONCLUSION

It is possible for substance use disorder screening and referral to be implemented in every emergency department across the nation and beyond to help identify patients struggling with substance misuse and refer them to the appropriate treatment upon discharge. Substance use disorder screening and referral are an evidence-based method, and sufficient evidence supports the current practice of emergency departments implementing routine substance use disorder screening and referral as standard of care.

Interventions to reduce self-stigma in people who use drugs: A systematic review

BACKGROUND

Substance use stigma is a key barrier to treatment and harm reduction engagement among people who use drugs (PWUD). Previous systematic reviews have focused on interventions to reduce stigma in healthcare providers and the public; less is known about interventions to address self-stigma among PWUD. The purpose of this review is to evaluate the evidence for substance use self-stigma reduction interventions.

METHODS

We reviewed English-language studies published between 2011 and 2023 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO #CRD42022321305). We searched seven bibliographic databases (PubMed; SCOPUS; APA PsycInfo; CINAHL; Social Work Abstracts; Sociological Abstracts; ProQuest Dissertations & Theses). This review included studies if 1) they evaluated the effectiveness of a psychosocial intervention, 2) participants were PWUD, 3) authors reported self-stigma as a primary outcome, 4) the study design was experimental or quasi-experimental. We reviewed, interpreted and reported intervention characteristics and effectiveness using narrative synthesis. We assessed study quality with the Downs & Black checklist.

RESULTS

Among 1195 screened studies, 15 met the inclusion criteria (N = 2280 PWUD). We categorized the interventions according to three approaches: psychotherapeutic (n = 8), psychoeducational (n = 5), and multimodal (n = 2). Most interventions were delivered in clinical settings (n = 11) and in a group format (n = 13). Study quality was fair-to-good and included nine randomized controlled trials (RCTs) and six quasi-experiments. Measurement heterogeneity was high, with 11 different stigma-related scales used across the 15 studies. Eleven studies showed significant favorable effects in at least one stigma measure. Six of these demonstrated positive effects in all stigma measures. Evidence was mixed for all three intervention categories; however, Acceptance and Commitment Therapy, a form of group psychotherapy, demonstrated effectiveness in four of five RCTs incorporating this approach.

CONCLUSIONS

Overall, there is promising evidence for the effectiveness of substance use self-stigma interventions, although more studies are needed to determine which approaches are most effective. Consistent conceptualization and measurement of self-stigma across studies will improve comparability in future intervention trials. Current offerings are largely limited to clinical settings and group-based formats; self-help interventions, available for other stigmatized conditions, could be developed to serve the majority of PWUD not engaged in treatment.

Strategies to support substance use disorder care transitions from acute-care to community-based settings: a scoping review and typology

BACKGROUND

Acute-care interventions that identify patients with substance use disorders (SUDs), initiate treatment, and link patients to community-based services, have proliferated in recent years. Yet, much is unknown about the specific strategies being used to support continuity of care from emergency department (ED) or inpatient hospital settings to community-based SUD treatment. In this scoping review, we synthesize the existing literature on patient transition interventions, and form an initial typology of reported strategies.

METHODS

We searched Pubmed, Embase, CINAHL and PsychINFO for peer-reviewed articles published between 2000 and 2021 that studied interventions linking patients with SUD from ED or inpatient hospital settings to community-based SUD services. Eligible articles measured at least one post-discharge treatment outcome and included a description of the strategy used to promote linkage to community care. Detailed information was extracted on the components of the transition strategies and a thematic coding process was used to categorize strategies into a typology based on shared characteristics. Facilitators and barriers to transitions of care were synthesized using the Consolidated Framework for Implementation Research.

RESULTS

Forty-five articles met inclusion criteria. 62% included ED interventions and 44% inpatient interventions. The majority focused on patients with opioid (71%) or alcohol (31%) use disorder. The transition strategies reported across studies were heterogeneous and often not well described. An initial typology of ten transition strategies, including five pre- and five post-discharge transition strategies is proposed. The most common strategy was scheduling an appointment with a community-based treatment provider prior to discharge. A range of facilitators and barriers were described, which can inform efforts to improve hospital-to-community transitions of care.

CONCLUSIONS

Strategies to support transitions from acute-care to community-based SUD services, although critical for ensuring continuity of care, vary greatly across interventions and are inconsistently measured and described. More research is needed to classify SUD care transition strategies, understand their components, and explore which lead to the best patient outcomes.

Text Messages Exchanged Between Individuals With Opioid Use Disorder and Their mHealth e-Coaches: Content Analysis Study

BACKGROUND

Opioid use disorder (OUD) has affected 2.2 million people in the United States. About 7.2 million people reported using illicit drugs in 2019, which contributed to over 70,000 overdose deaths. SMS text messaging interventions have been shown to be effective in OUD recovery. However, the interpersonal communication between individuals in OUD treatment and a support team on digital platforms has not been well examined.

OBJECTIVE

This study aims to understand the communication between participants undergoing OUD recovery and their e-coaches by examining the SMS text messages exchanged from the lens of social support and the issues related to OUD treatment.

METHODS

A content analysis of messages exchanged between individuals recovering from OUD and members of a support team was conducted. Participants were enrolled in a mobile health intervention titled "uMAT-R," a primary feature of which is the ability for patients to instantly connect with a recovery support staff or an "e-coach" via in-app messaging. Our team analyzed dyadic text-based messages of over 12 months. In total, 70 participants' messages and 1196 unique messages were analyzed using a social support framework and OUD recovery topics.

RESULTS

Out of 70 participants, 44 (63%) were between the ages of 31 and 50 years, 47 (67%) were female, 41 (59%) were Caucasian, and 42 (60%) reported living in unstable housing conditions. An average of 17 (SD 16.05) messages were exchanged between each participant and their e-coach. Out of 1196 messages, 64% (n=766) messages were sent by e-coaches and 36% (n=430) by participants. Messages of emotional support occurred the most, with 196 occurrences (n=9, 0.8%) and e-coaches (n=187, 15.6%). Messages of material support had 110 occurrences (participants: n=8, 0.7%; e-coaches: n=102, 8.5%). With OUD recovery topics, opioid use risk factors appeared in most (n=72) occurrences (patient: n=66, 5.5%; e-coach: n=6, 0.5%), followed by a message of avoidance of drug use 3.9% (n=47), which occurred mainly from participants. Depression was correlated with messages of social support (r=0.27; P=.02).

CONCLUSIONS

Individuals with OUD who had mobile health needs tended to engage in instant messaging with the recovery support staff. Participants who are engaged in messaging often engage in conversations around risk factors and avoidance of drug use. Instant messaging services can be instrumental in providing the social and educational support needs of individuals recovering from OUD.

Applying User-Centered Design in the Development of a Supportive mHealth App for Women in Substance Use Recovery

PURPOSE AND APPROACH

Women in recovery describe stigma, negative treatment, and limited support as barriers to achieving their health and parenting goals. Mobile health technologies carefully tailored to support the unique needs of recovery communities can provide less burdensome alternatives to in-person services for women transitioning out of substance use treatment. An iterative design process integrated women's interests into the structure, content, and interaction flow of a mobile health (mHealth) app.

SETTING AND PARTICIPANTS

Participants included women in recovery from opioid, alcohol, and polysubstance use disorders in a comprehensive housing program in urban Arizona.

METHODS

Five focus groups with 3-7 participants each (n = 27 total) informed creation of the mHealth app. Informed by theoretical models of usability and person-centered design, development involved an iterative series of focus groups in which we asked women to comment on interest in using each feature. This provided a qualitative priority framework for feature development. We then modified the app and repeated the process to gauge consensus and continually refine our prototype.

RESULTS

Women were interested in access to resources, such as housing, counseling, and parenting advice in settings known to treat women in recovery with respect. They also asked for positive messages, chatting with peers, and access to expert answers. They were less interested in points-based learning modules and "scored" activities, leading us to develop a "daily challenges" concept that builds good habits, but does not feel like "classwork". Women's recommendations shaped an mHealth app tailored to maximize utility, access, and safety for this at-risk population.

CONCLUSION

Integration of user-centered design with applied ethnographic techniques guided the development of a custom-tailored mHealth app responsive to lived experiences and needs of women in recovery. Future research should evaluate the potential for user-centered apps to increase self-efficacy, perceived social support, and to reduce risk of relapse.

Factors related to substance use treatment attendance after peer recovery coach intervention in the emergency department

Introduction

Brief intervention with peer recovery coach support has been used to generate referrals to substance use disorder treatment from the emergency department (ED). This retrospective study evaluated factors associated with successful linkage to treatment following brief intervention in the ED.

Methods

Data were extracted from the electronic health record for patients who were referred to substance use treatment from the ED and for whom follow-up data regarding treatment attendance was available (n=666). We examined associations between demographic and insurance variables, substance use, mental health diagnosis, prior abstinence, and stage of change with successful linkage to substance use treatment after ED referral.

Results

The sample was majority male (68%), White (62%), and had a mean age of 43 years (SD=12). Medicaid was the most common insurance (49%) followed by employer/private (34%). Multivariable logistic regression determined patients with Medicaid (OR=2.94, 95% CI:2.09-4.13, p=<.001), those who had a documented alcohol use disorder diagnosis (OR=1.59, 95% CI:1.074-2.342, p=.02), and those in the "Action" stage of change (OR=2.33, 95% CI:1.47-3.69, p=<.001) had greater odds of being successfully linked to treatment.

Conclusions

These results identify characteristics of patients available in the health record to determine who is more likely or less likely to attend substance use treatment following ED referral. Given appropriate screening, this information could be used to direct standard care resources to those with high likelihood of treatment attendance and strengthen follow-up interventions with peer recovery coaches for those with lower likelihood of treatment attendance.

Emergency Department Nurses' Perceptions of Patient Substance Use, Impact on Sexual Assault Care, and Access to Follow-up Behavioral Health Resources

INTRODUCTION

Patients may present to the emergency department for sexual assault care under the influence of drugs or alcohol. However, many emergency nurses are not prepared to meet their unique needs or aware of follow-up behavioral health resources. The purpose of this study was to (1) summarize current resources provided to patients and processes for referral to behavioral health services after sexual assault care, (2) explore emergency nurses' attitudes and behaviors toward patient substance use, and (3) explore nurses' perceptions of adjunct mobile health interventions for follow-up behavioral health care and describe anticipated barriers to use.

METHODS

Fifteen emergency nurses participated in semi-structured qualitative interviews.

RESULTS

Participants had mixed perceptions of patient intoxication during sexual assault care. They felt that conversations about substance use may be more appropriate after the ED visit. Participants recognized the opportunity to connect ED patients with substance use treatment or prevention resources but perceived that there are few local service providers. Most participants were not referring patients with substance use issues to behavioral health services after sexual assault care and said that their emergency departments did not have processes for referral to these services. Acceptability of mobile health for follow-up behavioral health care was high, but participants had concerns for patient privacy and internet access. Participants gave recommendations to improve referral practices and patient engagement with mobile health interventions.

DISCUSSION

This study highlights the need for emergency nurses to consider patient intoxication during sexual assault care and opportunities to connect patients with resources post-assault.

Implementing a text-messaging intervention for unhealthy alcohol use in emergency departments: protocol for implementation strategy development and a pilot cluster randomized implementation trial

BACKGROUND

Unhealthy alcohol use (UAU) is a leading cause of premature mortality among adults in the USA. Emergency departments (EDs) are key intervention settings for UAU but often have limited time and resources. One low-burden, scalable approach to address UAU is text-messaging interventions. Despite strong research support and promise for scalability, there is little research on how to implement such interventions in healthcare settings. The process of providers making them available to patients in an efficient way within already busy and overburdened ED workflows and patients adopting them remains a new area of research. The purpose of this three-phase study is to develop and test an implementation strategy for UAU text-messaging interventions in EDs.

METHOD

Our first aim is to examine barriers and facilitators to staff offering and patients accepting a text-messaging intervention in the ED using an explanatory, sequential mixed methods approach. We will examine alcohol screening data in the electronic health records of 17 EDs within a large integrated health system in the Northeast and conduct surveys among chairpersons in each. This data will be used to purposively sample 4 EDs for semi-structured interviews among 20 clinical staff, 20 patients, and 4 chairpersons. Our second aim is to conduct a stakeholder-engaged intervention mapping process to develop a multi-component implementation strategy for EDs. Our third aim is to conduct a mixed method 2-arm cluster randomized pilot study in 4 EDs that serve ~11,000 UAU patients per year to assess the feasibility, acceptability, and preliminary effectiveness of the implementation strategy. The Integrated Promoting Action on Research Implementation in Health Services framework will guide study activities.

DISCUSSION

Low-burden technology, like text messaging, along with targeted implementation support and strategies driven by identified barriers and facilitators could sustain large-scale ED-based alcohol screening programs and provide much needed support to patients who screen positive while reducing burden on EDs. The proposed study would be the first to develop and test this targeted implementation strategy and will prepare for a larger, fully powered hybrid effectiveness-implementation trial. Findings may also be broadly applicable to implementation of patient-facing mobile health technologies.

Assessment of Patient-Reported Naloxone Acquisition and Carrying With an Automated Text Messaging System After Emergency Department Discharge in Philadelphia

IMPORTANCE

A central tenet of harm reduction and prevention of opioid overdose deaths is the distribution and use of naloxone. Patient-centered methods that investigate naloxone acquisition and carrying can guide opioid overdose education and naloxone distribution efforts.

OBJECTIVE

To assess patients' self-reported naloxone acquisition and carrying after an emergency department (ED) encounter using automated text messaging.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study investigated self-reported patient behaviors involving naloxone after ED discharge in a large, urban academic health system in Philadelphia, Pennsylvania. Adult patients who were prescribed or dispensed naloxone and who had a mobile phone number listed in the electronic health record provided informed consent after ED discharge, and data were collected prospectively using text messaging from October 10, 2020, to March 19, 2021. Patients who did not respond to the survey or who opted out were excluded.

EXPOSURE

Automated text message-based survey after ED discharge for patients who were prescribed or dispensed naloxone.

MAIN OUTCOMES AND MEASURES

The primary outcome was patient-reported naloxone acquisition, carrying, and use. Descriptive statistics were used to summarize patient demographic characteristics.

RESULTS

Of 205 eligible patients, 41 (20.0%) completed the survey; of those patients, the mean (SD) age was 39.5 (13.7) years, and 21 (51.2%) were women. Fifteen (36.6%) had a personal history of being given naloxone after an overdose. As indicated by the ED record, 27 participants (65.9%) had naloxone dispensed in the ED, and 36 (87.8%) self-reported acquiring naloxone during or after their ED visit. Twenty-four participants (58.5%) were not carrying naloxone in the week before their ED visit. Twenty participants (48.8%) were carrying naloxone after the ED visit, and 27 (65.9%) reported planning to continue carrying naloxone in the future. Of the 24 individuals (58.5%) not carrying naloxone before their ED encounter, 13 (54.2%) reported planning to continue carrying naloxone in the future.

CONCLUSIONS AND RELEVANCE

In this cohort study of adult patients dispensed or prescribed naloxone from the ED, most reported acquiring naloxone on or after discharge. The ED remains a key point of access to naloxone for individuals at high risk of opioid use and overdose, and text messaging could be a method to engage and motivate patient-reported behaviors in enhancing naloxone acquisition and carrying.

Breaching Trust: A Qualitative Study of Healthcare Experiences of People Who Use Drugs in a Rural Setting

Background: Increased drug use has disproportionately impacted rural areas across the U.S. People who use drugs are at risk of overdose and other medical complications, including infectious diseases. Understanding barriers to healthcare access for this often stigmatized population is key to reducing morbidity and mortality, particularly in rural settings where resources may be limited. Methods: We conducted 20 semi-structured interviews with people who use drugs, including 17 who inject drugs, in rural southern Illinois between June 2018 and February 2019. Interviews were analyzed using a modified grounded theory approach where themes are coded and organized as they emerge from the data. Results: Participants reported breaches of trust by healthcare providers, often involving law enforcement and Emergency Medical Services, that dissuaded them from accessing medical care. Participants described experiences of mistreatment in emergency departments, with one account of forced catheterization. They further recounted disclosures of protected health information by healthcare providers, including communicating drug test results to law enforcement and sharing details of counseling sessions with community members without consent. Participants also described a hesitancy common among people who use drugs to call emergency medical services for an overdose due to fear of arrest. Conclusion: Breaches of trust by healthcare providers in rural communities discouraged people who use drugs from accessing medical care until absolutely necessary, if at all. These experiences may worsen healthcare outcomes and further stigmatize this marginalized community. Structural changes including reforming and clarifying law enforcement's role in Emergency Departments as well as instituting diversion policies during arrests may help rebuild trust in these communities. Other possible areas for intervention include stigma training and harm reduction education for emergency medicine providers, as well as developing and implementing referral systems between Emergency Departments and local harm reduction providers and medically assisted drug treatment programs.

The Use of Text Messaging to Improve Clinical Engagement for Individuals With Psychosis: Systematic Review

BACKGROUND

Individuals experiencing psychosis are at a disproportionate risk for premature disengagement from clinical treatment. Barriers to clinical engagement typically result from funding constraints causing limited access to and flexibility in services. Digital strategies, such as SMS text messaging, offer a low-cost alternative to potentially improve engagement. However, little is known about the efficacy of SMS text messaging in psychosis.

OBJECTIVE

This review aimed to address this gap, providing insights into the relationship between SMS text messaging and clinical engagement in the treatment of psychosis.

METHODS

Studies examining SMS text messaging as an engagement strategy in the treatment of psychosis were reviewed. Included studies were published from the year 2000 onward in the English language, with no methodological restrictions, and were identified using 3 core databases and gray literature sources.

RESULTS

Of the 233 studies extracted, 15 were eligible for inclusion. Most studies demonstrated the positive effects of SMS text messaging on dimensions of engagement such as medication adherence, clinic attendance, and therapeutic alliance. Studies examining the feasibility of SMS text messaging interventions found that they are safe, easy to use, and positively received.

CONCLUSIONS

Overall, SMS text messaging is a low-cost, practical method of improving engagement in the treatment of psychosis, although efficacy may vary by symptomology and personal characteristics. Cost-effectiveness and safety considerations were not adequately examined in the studies included. Future studies should consider personalizing SMS text messaging interventions and include cost and safety analyses to appraise readiness for implementation.

Incidence and predictors of drug overdoses among a cohort of >10,000 patients treated for substance use disorder

BACKGROUND

Drug overdoses remain a significant public health burden throughout the world. This study assessed the incidence and predictors of non-fatal and fatal drug overdoses among patients with an opioid use, treated for drug use disorders (DUD) at public treatment centers in Denmark.

METHODS

A consecutive cohort of patients (n = 11,199) were tracked from date of first registered enrollment between the year 2000 and 2010 to first registered drug overdose, death or December 31st 2010, whichever occurred first. Competing-risks regression models were fitted to estimate the sub hazard ratios (SHRs) of non-fatal and fatal drug overdoses and confounding risk factors.

RESULTS

A total of 3186 (28%) patients experienced a non-fatal drug overdose during follow-up, and 572 (6%) died from an overdose. Use of benzodiazepines (SHR: 1.15 95% CI 1.03, 1.28) was significantly associated with non-fatal overdose. Intravenous drug use and previous hospitalization for a non-fatal overdose increased the risk of later non-fatal (SHR: 1.57 95% CI 1.42, 1.73) and fatal overdoses (SHR: 1.43 95% CI 1.12, 1.82).

CONCLUSIONS

Patients who use opioids remain at risk of overdoses for a long time after discharge from drug treatment. Besides relevant monitoring and psychosocial support in opioid maintenance treatment, there is a need for informing and educating opioid users in risk factors and preventive measures in settings where they are often difficult to access for traditional treatment services.

A Multifaceted Intervention to Improve Patient Knowledge and Safe Use of Opioids: Results of the ED EMC2 Randomized Controlled Trial

OBJECTIVES

Despite increased focus on opioid prescribing, little is known about the influence of prescription opioid medication information given to patients in the emergency department (ED). The study objective was to evaluate the effect of an Electronic Medication Complete Communication (EMC² ) Opioid Strategy on patients' safe use of opioids and knowledge about opioids.

METHODS

This was a three-arm prospective, randomized controlled pragmatic trial with randomization occurring at the physician level. Consecutive discharged patients at an urban academic ED (>88,000 visits) with new hydrocodone-acetaminophen prescriptions received one of three care pathways: 1) usual care, 2) EMC² intervention, or 3) EMC²  + short message service (SMS) text messaging. The ED EMC² intervention triggered two patient-facing educational tools (MedSheet, literacy-appropriate prescription wording [Take-Wait-Stop]) and three provider-facing reminders to counsel (directed to ED physician, dispensing pharmacist, follow-up physician). Patients in the EMC²  + SMS arm additionally received one text message/day for 1 week. Follow-up at 1 to 2 weeks assessed "demonstrated safe use" (primary outcome). Secondary outcomes including patient knowledge and actual safe use (via medication diaries) were assessed 2 to 4 days and 1 month following enrollment.

RESULTS

Among the 652 enrolled, 343 completed follow-up (57% women; mean ± SD age = 42 ± 14.0 years). Demonstrated safe opioid use occurred more often in the EMC² group (adjusted odds ratio [aOR] = 2.46, 95% confidence interval [CI] = 1.19 to 5.06), but not the EMC²  + SMS group (aOR = 1.87, 95% CI = 0.90 to 3.90) compared with usual care. Neither intervention arm improved medication safe use as measured by medication diary data. Medication knowledge, measured by a 10-point composite knowledge score, was greater in the EMC²  + SMS group (β = 0.57, 95% CI = 0.09 to 1.06) than usual care.

CONCLUSIONS

The study found that the EMC² tools improved demonstrated safe dosing, but these benefits did not translate into actual use based on medication dairies. The text-messaging intervention did result in improved patient knowledge.
