Machine Learning for Predicting Risk of Early Dropout in a Recovery Program for Opioid Use Disorder.

BACKGROUND: An increase in opioid use has led to an opioid crisis during the last decade, leading to declarations of a public health emergency. In response to this call, the Houston Emergency Opioid Engagement System (HEROES) was established and created an emergency access pathway into long-term recovery for individuals with an opioid use disorder. A major contributor to the success of the program is retention of the enrolled individuals in the program. METHODS: We have identified an increase in dropout from the program after 90 and 120 days. Based on more than 700 program participants, we developed a machine learning approach to predict the individualized risk for dropping out of the program. RESULTS: Our model achieved sensitivity of 0.81 and specificity of 0.65 for dropout at 90 days and improved the performance to sensitivity of 0.86 and specificity of 0.66 for 120 days. Additionally, we identified individual risk factors for dropout, including previous overdose and relapse and improvement in reported quality of life. CONCLUSIONS: Our informatics approach provides insight into an area where programs may allocate additional resources in order to retain high-risk individuals and increase the chances of success in recovery.

Feasibility and outcomes from an integrated bridge treatment program for opioid use disorder.

OBJECTIVE: With a significant proportion of individuals with opioid use disorder not currently receiving treatment, it is critical to find novel ways to engage and retain patients in treatment. Our objective is to describe the feasibility and preliminary outcomes of a program that used emergency physicians to initiate a bridge treatment, followed by peer support services, behavioral counseling, and ongoing treatment and follow-up. METHODS: We developed a program called the Houston Emergency Opioid Engagement System (HEROES) that provides rapid access to board-certified emergency physicians for initiation of buprenorphine, plus at least 1 behavioral counseling session and 4 weekly peer support sessions over the course of 30 days. Follow-ups were conducted by phone and in person to obtain patient-reported outcomes. Primary outcomes included percentage of patients who completed the 30-day program and the percentage for successful linkage to more permanent ongoing treatment after the initial program. RESULTS: There were 324 participants who initiated treatment on buprenorphine from April 2018 to July 2019, with an average age of 36 (±9.6 years) and 52% of participants were males. At 30 days, 293/324 (90.43%) completed the program, and 203 of these (63%) were successfully connected to a subsequent community addiction medicine physician. There was a significant improvement (36%) in health-related quality of life. CONCLUSION: Lack of insurance is a predictor for treatment failure. Implementation of a multipronged treatment program is feasible and was associated with positive patient-reported outcomes. This approach holds promise as a strategy for engaging and retaining patients in treatment.

Prevalence and charges of opioid-related visits to U.S. emergency departments.

OBJECTIVE: An overwhelming responsibility for responding to the opioid epidemic falls on hospital emergency departments (ED). We sought to examine the overall prevalence rate and associated charges of opioid-related diagnoses and overdoses. Although charge data do not necessarily represent cost, they are proxy indicators of resource utilization and burden. METHODS: We conducted a retrospective study of the National Emergency Department Sample (NEDS) dataset, the largest all-payer ED database in the United States. We queried using specific relevant ICD-10 codes to estimate the number of adult ED visits for both opioid poisonings and other opioid-related diagnoses during 2016 and 2017, which was the most recent publicly available data. Prevalence rates and financial charges were calculated by year and odds ratios were used to examine differences. RESULTS: Of approximately 234 million adult visits to EDs across 2016 and 2017, 2.88 million (1.23%) were related to opioids, with overdoses comprising nearly 27.5% and visits for other opioid-related diagnoses totaling 72.5%. As the primary diagnosis, opioids were responsible for 37% of all ED visits across both years. Total opioid-related visits for the two years accounted for $9.57 billion in ED charges, or $4.78 billion annually, with Medicaid and Medicare responsible for 66% of all charges. CONCLUSION AND RELEVANCE: Approximately one of every 80 visits to the ED were opioid-related, leading to financial charges approaching $5 billion per year. Since both prevalence and the economic burden of opioid-related visits are high, targeted interventions to address this epidemic's impact on healthcare systems should be a national priority.

A Framework for EMS Outreach for Drug Overdose Survivors: A Case Report of the Houston Emergency Opioid Engagement System.

OBJECTIVE: Fatalities from drug-induced overdoses in the United States have taken greater than 292,000 lives in the last five years, and nearly two-thirds of these are opioid-related. The burden on prehospital emergency medical services (EMS) to respond to these incidents is growing. The standard of care typically involves overdose reversal and rapid transport, although a few agencies have begun to use community paramedicine to more proactively follow-up, initiate treatment, and refer patients to addiction medicine providers. Methods: In this manuscript we share the details of an outreach case study to serve as a blueprint for other agencies and municipalities to adopt and refine. The University of Texas Health Science Center, in partnership with the Houston Fire Department and other local first responder agencies, developed a program in Houston, Texas based on rapid response to post-overdose survivors using available incident data from the primary municipal agencies. Results: The Houston Emergency Opioid Engagement System (HEROES) was created to more comprehensively address the opioid epidemic. By utilizing data extracted from the patient care record system, a team comprised of a peer recovery coach and a paramedic is dispatched to the home location of a recent overdose (OD) incident to provide outreach. Conclusions: Outreach dialog and motivational interviewing techniques are used to provide awareness of treatment options and to engage individuals into a treatment program. A case report of this program and recommendations for broader adoption are presented.

Telehealth sustains patient engagement in OUD treatment during COVID-19.

The coronavirus disease pandemic of 2019 (COVID-19) has created significant economic and societal burden, with mortality currently exceeding 615,000 and millions of others affected worldwide. For those with opioid use disorder (OUD), however, the impact on this vulnerable population could be even more severe. The objective of this study was to outline our organizational telehealth adaptations that enabled virtual counseling, peer support, groups, and provider care during COVID-19 in one community-based opioid treatment program. We utilized an observational study design during March to June 2020, during the initial peak of COVID-19 in the U.S. After we closed our facility for the first five business days, we rapidly enacted virtual care with telehealth for peer coaching, counseling, groups, and provider visits. While we lost patient volume during the initial weeks, we observed an overall increase in patient engagement over time. Future state and federal policy should focus on maintaining less stringent policies around the use of telehealth, prescribing, and in-person exams for medication for OUD.

Alternatives to Arrest for Illicit Opioid Use: A Joint Criminal Justice and Healthcare Treatment Collaboration.

Opioid overdoses continue to be a leading cause of death in the US. This public health crisis warrants innovative responses to help prevent fatal overdose. There is continued advocacy for collaborations between public health partners to create joint responses. The high correlation between persons with opioid use disorder who have a history of involvement in the criminal justice system is widely recognized, and allows for treatment intervention opportunities. Law enforcement-led treatment initiatives are still relatively new, with a few sparse early programs emerging almost a decade ago and only gaining popularity in the past few years. A lack of published methodologies creates a gap in the knowledge of applied programs that are effective and can be duplicated. This article seeks to outline an interagency relationship between police and healthcare that illustrates arrest is not the only option that law enforcement may utilize when encountering persons who use illicit substances. Program methods of a joint initiative between law enforcement and healthcare in a large, metropolitan area will be reviewed, supplemented with law enforcement overdose data and statistics on law enforcement treatment referrals.

Developing interagency collaboration to address the opioid epidemic: A scoping review of joint criminal justice and healthcare initiatives.

BACKGROUND: With the current opioid epidemic impacting well over half of all counties across the United States, initiatives that encourage interagency collaboration between first responder organizations appear necessary to comprehensively address this crisis. Police, fire, and emergency medical services (EMS) are in a unique position to identify substance users and provide necessary resources to initiate treatment, yet there is not sufficient evidence of joint collaborative programs between law enforcement/first responders and healthcare providers. METHODS: In this scoping review we examine the current state of joint criminal justice and healthcare interventions, specifically, opioid and substance use pre-arrest initiatives via emergency first responders and police officers. We relied on data from the last 10 years across three major databases to assess the extent of criminal justice (CJ) and healthcare collaborations as a response to individuals with opioid use disorder (OUD). We specifically focused on interventional programs between criminal justice first responders (pre-arrest) and healthcare providers where specific outcomes were documented. RESULTS: We identified only a small number (6) of studies involving interventions that met this criteria, suggesting very limited study of joint interagency collaboration between law enforcement first responders and healthcare providers. Most had small samples, none were in the southern states, and all but one were initiated within the last 5 years. CONCLUSIONS: Although studies describing joint efforts of early intercept criminal justice responses and healthcare interventions were few, existing studies suggest that such programs were effective at improving treatment referral and retention outcomes. Greater resources are needed to encourage criminal justice and healthcare collaboration and policies, making it easier to share data, refer patients, and coordinate care for individuals with OUD.

Outreach to people who survive opioid overdose: Linkage and retention in treatment.

Cognitive motivation theories contend that individuals have greater readiness for behavioral change during critical periods or life events, and a non-fatal overdose could represent such an event. The objective of this study was to examine if the use of a specialized mobile response team (assertive outreach) could help identify, engage, and retain people who have survived an overdose into a comprehensive treatment program. We developed an intervention, consisting of mobile outreach followed by medication and behavioral treatment, in Houston Texas between April and December 2018. Our primary outcome variables were the level of willingness to engage in treatment, and percent who retained in treatment after 30 and 90 day endpoints. We screened 103 individuals for eligibility, and 34 (33%) elected to engage in the treatment program, while two-thirds chose not to engage in treatment, primarily due to low readiness levels. The average age was 38.2 ± 12 years, 56% were male, 79% had no health insurance, and the majority (77%) reported being homeless or in temporary housing. There were 30 (88%) participants still active in the treatment program after 30 days, and 19 (56%) after 90 days. Given the high rates of relapse using conventional models, which wait for patients to present to treatment, our preliminary results suggest that assertive outreach could be a promising strategy to motivate people to enter and remain in long-term treatment.

Prevalence of Mental Health Disorders among Individuals Enrolled in an Emergency Response Program for Treatment of Opioid Use Disorder.

BACKGROUND: Psychiatric co-occurring disorders among individuals with opioid use disorder has primarily focused on epidemiological surveys of patients in continuous or long-term treatment, yet little is known about the socio-economically vulnerable who are non-treatment seeking prior to an emergency response. METHODS: We retrospectively analyzed data from patients who had enrolled in a study involving home outreach to patients referred from police, emergency medical services (EMS), or hospital emergency departments following an emergency response. The sample is largely socio-economically vulnerable with high rates of unemployment and uninsured. Eligible consenting patients received an intervention consisting of medication (buprenorphine), behavioral counseling, and peer support. Participants completed semi-structured, psychological instruments to assess current and prior history for both substance use and mental health disorders. We used descriptive statistics to evaluate rates of co-occurring mental health comorbidity. RESULTS: Among 102 patients (average age = 36.5 years old), approximately 61 (59.8%) reported a prior mental health diagnosis, with 31 (30.3%) currently on medications for their diagnoses. Mood and anxiety disorders were most frequently recorded. Just over half (51%) had received any prior treatment for their substance use. Of those with dual disorders, 67.2% had experienced prior suicidal thoughts, and 63.7% reported polysubstance use of 5 or more substances. CONCLUSION: Co-occurring psychiatric disorders, and specifically mood and anxiety disorders, appear to be prevalent in vulnerable populations at an increased rate. Mental health assessments should routinely be performed in the emergency setting and in early stages of treatment.

Emergency medical services targeting opioid user disorder: An exploration of current out-of-hospital post-overdose interventions.

OBJECTIVE: The opioid epidemic continues to escalate, and out-of-hospital emergency medical services (EMS) play a vital role in acute overdose reversal, but could serve a broader role post-incident for follow-up, outreach, and referrals. Our objective is to identify the scope and prevalence of community-based, post-opioid overdose EMS programs across the United States. METHODS: We used a narrative review of prior studies in PubMed and Scopus for the last 20 years (1999-2020) to identify relevant medical literature and a web search to identify gray literature of EMS interventions involving opioids. RESULTS: Out of nearly 22,000 EMS agencies across the United States, we found evidence of only 27 programs published in medical or gray literature involving post-overdose interventions. They were most commonly found in the north and eastern region of the country. Although most of these programs incorporate harm reduction and education, other more innovative aspects such as linkage to outpatient addiction treatment or peer support services, are much less common. The most comprehensive programs involved combinations of innovative outreach, specialized referrals, integration with police and criminal justice, peer support, and even treatment initiation. CONCLUSIONS: Out-of-hospital emergency care has the potential to provide more comprehensive care after drug overdose, but many programs either do not currently have such an intervention in place, or are not disseminating their practices for other agencies to assimilate. EMS protocols and policies that encourage greater adoption of active community paramedicine practices for opioids should be encouraged.
