Does this patient really want treatment? Factors associated with baseline and evolving readiness for change among hospitalized substance using adults interested in treatment

"Every Time I Go in There, It Gives Me Time to Reflect": A Qualitative Study of Patient Perspectives on Substance Use, Medications for Opioid Use Disorder, and Harm Reduction Following Hospitalization for Serious Injection-Related Infection

Background

Serious injection-related infections (SIRIs) have high morbidity and mortality, in part from incomplete antibiotic treatment, ongoing substance use and reinfection. Understanding how hospitalizations for SIRIs affect patient perspectives on substance use, harm reduction, and medications for opioid use disorder (MOUD) in the era of hospital-based addiction services will inform efforts to improve care.

Methods

We conducted qualitative interviews at Boston Medical Center with individuals hospitalized with SIRIs between 2020 and 2024. To ensure diverse experiences, we recruited qualifying participants based on record of SIRI International Classification of Diseases, 10th Revision, codes, presence on the outpatient parenteral antibiotic program list, during hospitalizations, and from a drop-in harm reduction program. Interviews were transcribed, coded inductively, and analyzed for key themes.

Results

Participants with SIRIs (n = 30) had the following characteristics: Most had endocarditis (n = 10) or osteomyelitis (n = 9) and had completed the recommended antibiotics (n = 24); the mean age was 39; most were male (n = 19), White (n = 21), and housed (n = 18). Three key themes emerged after SIRI hospitalization: (1) reduced substance use and adoption of harm reduction practices were common; (2) perspectives on MOUD varied, but negative experiences and medication stigma persisted; and (3) SIRI hospitalizations were viewed as an opportunity for reflection on substance use and health.

Conclusions

SIRI hospitalizations and the postdischarge period are opportunities to engage patients in addiction and infectious disease care. Participants expressed ambivalence about MOUD despite access to robust hospital-based addiction medicine services. Longitudinal support that explicitly includes harm reduction and MOUD, both linkage and retention, is needed to improve care for people with SIRIs.

mHealth Incentivized Adherence Plus Patient Navigation (MIAPP): protocol for a pilot randomized controlled trial to improve linkage and retention on buprenorphine for hospitalized patients with methamphetamine use and opioid use disorder

BACKGROUND

Initiation of buprenorphine for treatment of opioid use disorder (OUD) in acute care settings improves access and outcomes, however patients who use methamphetamine are less likely to link to ongoing treatment. We describe the intervention and design from a pilot randomized controlled trial of an intervention to increase linkage to and retention in outpatient buprenorphine services for patients with OUD and methamphetamine use who initiate buprenorphine in the hospital.

METHODS

The study is a two-arm pilot randomized controlled trial (N = 40) comparing the mHealth Incentivized Adherence Plus Patient Navigation (MIAPP) intervention to treatment as usual. Development of the MIAPP intervention was guided by the information-motivation-behavioral skills model and combines financial rewards via mobile health-based adherence monitoring with the "human touch" of a patient navigator. Participants receive financial incentives for submitting videos of themselves taking buprenorphine via smartphone. The Patient Navigator reviews videos and provides treatment adherence coaching, care coordination and motivational enhancement. The intervention is introduced prior to hospital discharge and is offered for 30 days. The primary outcome is linkage to outpatient buprenorphine care within 30 days of hospital discharge. Secondary outcomes include retention on buprenorphine 90 days post discharge, hospital readmissions, and past 30-day methamphetamine use.

DISCUSSION

Interventions are needed to increase linkage and retention to outpatient buprenorphine among hospitalized patients with OUD, especially for people who co-use methamphetamine. We will examine the MIAPP intervention to improve buprenorphine adherence and linkage to outpatient treatment in a pilot randomized controlled trial which will provide valuable insights about research approaches for hospitalized patients with substance use disorder.

Medication for Opioid Use Disorder After Serious Injection-Related Infections in Massachusetts

Importance

Serious injection-related infections (SIRIs) cause significant morbidity and mortality. Medication for opioid use disorder (MOUD) improves outcomes but is underused. Understanding MOUD treatment after SIRIs could inform interventions to close this gap.

Objectives

To examine rehospitalization, death rates, and MOUD receipt for individuals with SIRIs and to assess characteristics associated with MOUD receipt.

Design, Setting, and Participants

This retrospective cohort study used the Massachusetts Public Health Data Warehouse, which included all individuals with a claim in the All-Payer Claims Database and is linked to individual-level data from multiple government agencies, to assess individuals aged 18 to 64 years with opioid use disorder and hospitalization for endocarditis, osteomyelitis, epidural abscess, septic arthritis, or bloodstream infection (ie, SIRI) between July 1, 2014, and December 31, 2019. Data analysis was performed from November 2021 to May 2023.

Exposure

Demographic and clinical factors potentially associated with posthospitalization MOUD receipt.

Main Outcomes and Measures

The main outcome was MOUD receipt measured weekly in the 12 months after hospitalization. We used zero-inflated negative binomial regression to examine characteristics associated with any MOUD receipt and rates of treatment in the 12 months after hospitalization. Secondary outcomes were receipt of any buprenorphine formulation, methadone, and extended-release naltrexone examined individually.

Results

Among 8769 individuals (mean [SD] age, 43.2 [12.0] years; 5066 [57.8%] male) who survived a SIRI hospitalization, 4305 (49.1%) received MOUD, 5919 (67.5%) were rehospitalized, and 973 (11.1%) died within 12 months. Of those treated with MOUD in the 12 months after hospitalization, the mean (SD) number of MOUD initiations during follow-up was 3.0 (1.7), with 956 of 4305 individuals (22.2%) receiving treatment at least 80% of the time. MOUD treatment after SIRI hospitalization was significantly associated with MOUD in the prior 6 months (buprenorphine: adjusted odds ratio [AOR], 16.51; 95% CI, 13.81-19.74; methadone: AOR, 28.46; 95% CI, 22.41-36.14; or naltrexone: AOR, 2.05; 95% CI, 1.56-2.69). Prior buprenorphine (incident rate ratio [IRR], 1.17; 95% CI, 1.11-1.24) or methadone (IRR, 1.89; 95% CI, 1.79-2.01) use was associated with higher treatment rates after hospitalization, and prior naltrexone use (IRR, 0.86; 95% CI, 0.77-0.95) was associated with lower rates.

Conclusions and Relevance

This study found that in the year after a SIRI hospitalization in Massachusetts, mortality and rehospitalization were common, and only half of patients received MOUD. Treatment with MOUD before a SIRI was associated with posthospitalization MOUD initiation and time receiving MOUD. Efforts are needed to initiate MOUD treatment during SIRI hospitalizations and subsequently retain patients in treatment.

Contextual barriers and enablers to establishing an addiction-focused consultation team for hospitalized adults with opioid use disorder

BACKGROUND

Hospitalization presents an opportunity to begin people with opioid use disorder (OUD) on medications for opioid use disorder (MOUD) and link them to care after discharge; regrettably, people admitted to the hospital with an underlying OUD typically do not receive MOUD and are not connected with subsequent treatment for their condition. To address this gap, we launched a multi-site randomized controlled trial to test the effectiveness of a hospital-based addiction consultation team (the Substance Use Treatment and Recovery Team (START)) consisting of an addiction medicine specialist and care manager team that provide collaborative care and a specified intervention to people with OUD during the inpatient stay. Successful implementation of new practices can be impacted by organizational context, though no previous studies have examined context prior to implementation of addiction consultation services (ACS). This study assessed pre-implementation context for implementing a specialized ACS and tailoring it accordingly.

METHODS

We conducted semi-structured interviews with hospital administrators, physicians, physician assistants, nurses, and social workers at the three study sites between April and August 2021 before the launch of the pragmatic trial. Using an analytical framework based on the Consolidated Framework for Implementation Research, we completed a thematic analysis of interview data to understand potential barriers or enablers and perceptions about acceptability and feasibility.

RESULTS

We interviewed 28 participants across three sites. The following themes emerged across sites: (1) START is an urgently needed model for people with OUD; (2) Intervention adaptations are recommended to meet local and cultural needs; (3) Linking people with OUD to community clinicians is a highly needed component of START; (4) It is important to engage stakeholders across departments and roles throughout implementation. Across sites, participants generally saw a need for change from usual care to support people with OUD, and thought the START was acceptable and feasible to implement. Differences among sites included tailoring the START to support the needs of varying patient populations and different perceptions of the prevalence of OUD.

CONCLUSIONS

Hospitals planning to implement an ACS in the inpatient setting may wish to engage in a systematic pre-implementation contextual assessment using a similar framework to understand and address potential barriers and contextual factors that may impact implementation. Pre-implementation work can help ensure the ACS and other new practices fit within each unique hospital context.

Exemplar Hospital initiation trial to Enhance Treatment Engagement (EXHIT ENTRE): protocol for CTN-0098B a randomized implementation study to support hospitals in caring for patients with opioid use disorder

BACKGROUND

Hospitalizations involving opioid use disorder (OUD) are increasing. Medications for opioid use disorder (MOUD) reduce mortality and acute care utilization. Hospitalization is a reachable moment for initiating MOUD and arranging for ongoing MOUD engagement following hospital discharge. Despite existing quality metrics for MOUD initiation and engagement, few hospitals provide hospital based opioid treatment (HBOT). This protocol describes a cluster-randomized hybrid type-2 implementation study comparing low-intensity and high-intensity implementation support strategies to help community hospitals implement HBOT.

METHODS

Four state implementation hubs with expertise in initiating HBOT programs will provide implementation support to 24 community hospitals (6 hospitals/hub) interested in starting HBOT. Community hospitals will be randomized to 24-months of either a low-intensity intervention (distribution of an HBOT best-practice manual, a lecture series based on the manual, referral to publicly available resources, and on-demand technical assistance) or a high-intensity intervention (the low-intensity intervention plus funding for a hospital HBOT champion and regular practice facilitation sessions with an expert hub). The primary efficacy outcome, adapted from the National Committee on Quality Assurance, is the proportion of patients engaged in MOUD 34-days following hospital discharge. Secondary and exploratory outcomes include acute care utilization, non-fatal overdose, death, MOUD engagement at various time points, hospital length of stay, and discharges against medical advice. Primary, secondary, and exploratory outcomes will be derived from state Medicaid data. Implementation outcomes, barriers, and facilitators are assessed via longitudinal surveys, qualitative interviews, practice facilitation contact logs, and HBOT sustainability metrics. We hypothesize that the proportion of patients receiving care at hospitals randomized to the high-intensity arm will have greater MOUD engagement following hospital discharge.

DISCUSSION

Initiation of MOUD during hospitalization improves MOUD engagement post hospitalization. Few studies, however, have tested different implementation strategies on HBOT uptake, outcome, and sustainability and only one to date has tested implementation of a specific type of HBOT (addiction consultation services). This cluster-randomized study comparing different intensities of HBOT implementation support will inform hospitals and policymakers in identifying effective strategies for promoting HBOT dissemination and adoption in community hospitals.

"It's time for a change. I need to. I have to": Substance misuse recovery turning points of unhoused Alaskans

Substance misuse is a pernicious health concern for many unhoused people. A deep understanding of turning points - what propels someone to take concrete action toward addressing substance misuse - is needed to inform recovery policies and practices. This study sought to identify common elements in turning points among unhoused people vis-à-vis a phenomenological qualitative approach. Twenty people (Mage = 47.47, SD = 9.75; 50% female) who self-identified as being in recovery while unhoused participated in semi-structured interviews in Anchorage, Alaska, a community with high rates of both houselessness and substance misuse. Survival (life- and health-sustaining), individual (intrapersonal), and relational (interpersonal) motivations all shaped turning points. Limitations include the possible underrepresentation of individuals using a harm-reduction approach or capturing differences by housing type. Programs to address substance misuse should consider these motivations. Future research should identify and refine turning points and work to understand how they interact with change processes.

More Than a Perioperative Surgical Home: An Opportunity for Anesthesiologists to Advance Public Health

Public health and the medical specialty of anesthesiology have been closely intertwined throughout history, dating back to the 1800s when Dr. John Snow used contact tracing methods to identify the Broad Street Pump as the source of a cholera outbreak in London. During the COVID-19 pandemic, leaders in anesthesiology and anesthesia patient safety came forward to develop swift recommendations in the face of rapidly changing evidence to help protect patients and healthcare workers. While these high-profile examples may seem like uncommon events, there are many common modern-day public health issues that regularly intersect with anesthesiology and surgery. These include, but are not limited to, smoking; chronic opioid use and opioid use disorder; and obstructive sleep apnea. As an evolving medical specialty that encompasses pre- and postoperative care and acute and chronic pain management, anesthesiologists are uniquely positioned to improve patient care and outcomes and promote long-lasting behavioral changes to improve overall health. In this article, we make the case for advancing the role of the anesthesiologist beyond the original perioperative surgical home model into promoting public health initiatives within the perioperative period.

Addiction Services for Veterans: Opportunities in Acute Care

OBJECTIVE

This study aimed to estimate the proportion of total hospital discharges that involved a primary or secondary substance-related diagnosis code (SubDx) on inpatient medicine, psychiatry, and surgery services as part of a needs assessment for inpatient addiction consultation at our large, academic-affiliated Veterans Affairs (VA) hospital.

METHODS

We first calculated the percentage of total and service-specific discharges with a primary or secondary substance-related International Classification of Disease, Tenth Revision , code on all inpatient services (medicine, psychiatry, and surgery) in Fiscal Year 2017, 2018, and 2019, using facility-level data. Second, we calculated the proportion of total discharges that involved alcohol- and opioid-related diagnoses.

RESULTS

Over the 3 years studied, 29% of total discharges had a SubDx (4469 of 15,575). The proportion of total discharges that involved a SubDx was 23% (1246 of 5449) in 2017, 31% (1664 of 5332) in 2018, and 33% in 2019 (1559 of 4794), a statistically significant increase ( P < 0.001). As a percentage of service-specific discharges, 65% of discharges from psychiatry (1446 of 2217) had a SubDx, compared with 25% from medicine (2469 of 9713), and 15% from surgery (554 of 3645). Medicine services had the most discharges with SubDx, with a year-over-year increase in the number of discharges with SubDx. The percentage of total discharges that involved alcohol- and opioid-related diagnoses was 14% and 4%, respectively.

CONCLUSIONS

Substance-related diagnoses are prevalent at our hospital and are increasing over time. The largest number of discharges with SubDx was found on medicine services. Alcohol-related diagnoses were nearly 4 times more prevalent than opioid-related diagnoses. We found focused need around alcohol use and alcohol withdrawal.

The Substance Use Treatment and Recovery Team (START) study: protocol for a multi-site randomized controlled trial evaluating an intervention to improve initiation of medication and linkage to post-discharge care for hospitalized patients with opioid use disorder

BACKGROUND

People with opioid use disorder experience high burden of disease from medical comorbidities and are increasingly hospitalized with medical complications. Medications for opioid use disorder are an effective, life-saving treatment, but patients with an opioid use disorder admitted to the hospital seldom initiate medication for their disorder while in the hospital, nor are they linked with outpatient treatment after discharge. The inpatient stay, when patients may be more receptive to improving their health and reducing substance use, offers an opportunity to discuss opioid use disorder and facilitate medication initiation and linkage to treatment after discharge. An addiction-focus consultative team that uses evidence-based tools and resources could address barriers, such as the need for the primary medical team to focus on the primary health problem and lack of time and expertise, that prevent primary medical teams from addressing substance use.

METHODS

This study is a pragmatic randomized controlled trial that will evaluate whether a consultative team, called the Substance Use Treatment and Recovery Team (START), increases initiation of any US Food and Drug Administration approved medication for opioid use disorder (buprenorphine, methadone, naltrexone) during the hospital stay and increases linkage to treatment after discharge compared to patients receiving usual care. The study is being conducted at three geographically distinct academic hospitals. Patients are randomly assigned within each hospital to receive the START intervention or usual care. Primary study outcomes are initiation of medication for opioid use disorder in the hospital and linkage to medication or other opioid use disorder treatment after discharge. Outcomes are assessed through participant interviews at baseline and 1 month after discharge and data from hospital and outpatient medical records.

DISCUSSION

The START intervention offers a compelling model to improve care for hospitalized patients with opioid use disorder. The study could also advance translational science by identifying an effective and generalizable approach to treating not only opioid use disorder, but also other substance use disorders and behavioral health conditions.

Housing Instability, Structural Vulnerability, and Non-Fatal Opioid Overdoses Among People Who Use Heroin in Washington Heights, New York City

Nationally, opioid overdose remains strikingly persistent among people experiencing homelessness and housing instability. Limited information is available about the characteristics of this phenomenon in economically disadvantaged communities of color. This study sought to evaluate the association between key contextual factors and experiencing a non-fatal opioid overdose among people who use heroin in Washington Heights, New York City. We conducted a cross-sectional survey (N = 101) among participants seeking harm reduction services who reported heroin use in the last three months. Binary logistic regression models examined the association between key social and structural factors and the likelihood of ever experiencing a non-fatal opioid overdose and recently experiencing a non-fatal opioid overdose. The majority of the sample reported housing instability and lived in poverty; almost 42% were homeless. After adjustment, participants who injected heroin were more likely to have ever experienced a non-fatal opioid overdose. Also, younger participants who reported hunger in the last six months were more likely to have experienced a non-fatal opioid overdose in the last three months. Findings suggest the role of structural vulnerability in shaping overdose risk among the participants. Overdose prevention strategies should consider factors of the social and economic environment to mitigate barriers to accessing health and social services within the context of the current opioid crisis.

Motherhood, pregnancy and gateways to intervene in substance use disorder

Motherhood increases women's use of health and social services, presenting opportunities to identify and refer women with substance use disorder (SUD) to treatment. We pooled 4 years (2015-2018) of cross-sectional data from National Survey on Drug Use and Health on women of child-bearing age (18-44) in the United States (n = 64,346). (1) We compared the use of services (health, social and criminal justice involvement) by SUD and 'motherhood' (pregnant or has one or more children under 18). We used multivariable logistic regression models to estimate the association between motherhood, SUD and their interaction with the use of services. (2) We estimated the association between the use of different services and SUD treatment use among women with SUD. Among women of child-bearing age, 9.7% had SUD. Mothers who had SUD were more likely to use social services (AOR = 1.48 [95% CI: 1.22, 1.79]) and mental health services compared with non-mothers who did not have SUD (AOR = 1.40 [95% CI: 1.19, 1.65]). The following factors were associated with increased odds of receiving SUD treatment among mothers: mental health treatment utilisation (AOR = 1.94 [95% CI: 1.29, 2.93]); Medicaid coverage (AOR = 2.48 [95% CI: 1.64, 3.76]); and criminal justice involvement (AOR = 3.38 [95% CI: 1.97, 5.80]). To increase treatment access, it is important to address women's different stages in life, including how to best engage women in SUD care across different settings.

Characteristics associated with motivation to stop substance use and improve skin and needle hygiene among hospitalized patients who inject drugs

Background: Hospitalizations for people who inject drugs (PWID) are opportunities to address substance use. However, little is known about hospitalized PWIDs' motivation to stop substance use or improve skin and needle hygiene, common means for reducing injection sequelae. Methods: We used baseline data from a randomized controlled trial of a behavioral intervention to improve skin and needle hygiene among 252 hospitalized PWID between January 2014 and June 2018. We examined motivation (scale 1-10) to stop substance use, use new needles, and clean skin and used multiple linear regression models to evaluate characteristics associated with these outcomes. Results: PWID were recruited during injection-related (154, 61.1%) and non-injection-related hospitalizations (98, 38.9%). Motivation to stop substance use was 7.11 (SD = 2.67), use new needles was 7.8 (SD = 1.9), and clean skin was 6.7 (SD = 2.3). In adjusted models, experiencing an injection-related hospitalization was not significantly associated (p > 0.05) with motivation to stop substance use (β = -0.76, SE = 0.299), use new needles (β = 0.301, SE = 0.255), or clean skin (β = 0.476, SE = 0.323). Number of past-year skin and soft tissue infections was negatively associated with motivation to use new needles (β = -0.109, SE = 0.049, p < 0.05) and clean skin (β = -0.131, SE = 0.062, p < 0.05). Greater opioid withdrawal was associated with lower motivation to use new needles (β = -0.275, SE = 0.92, p < 0.01). Conclusions: Among hospitalized PWID, motivation to stop substance use and improve skin and needle hygiene was moderately high, but injection-related hospitalizations were not associated with greater motivation. Efforts to reduce injection sequelae for all hospitalized PWID are needed.

Buprenorphine management in the perioperative period: educational review and recommendations from a multisociety expert panel

BACKGROUND

The past two decades have witnessed an epidemic of opioid use disorder (OUD) in the USA, resulting in catastrophic loss of life secondary to opioid overdoses. Medication treatment of opioid use disorder (MOUD) is effective, yet barriers to care continue to result in a large proportion of untreated individuals. Optimal analgesia can be obtained in patients with MOUD within the perioperative period. Anesthesiologists and pain physicians can recommend and consider initiating MOUD in patients with suspected OUD at the point of care; this can serve as a bridge to comprehensive treatment and ultimately save lives.

METHODS

The Board of Directors of the American Society of Regional Anesthesia and Pain Medicine, American Society of Anesthesiologists, American Academy of Pain Medicine, American Society of Addiction Medicine and American Society of Health System Pharmacists approved the creation of a Multisociety Working Group on Opioid Use Disorder, representing the fields of pain medicine, addiction, and pharmacy health sciences. An extensive literature search was performed by members of the working group. Multiple study types were included and reviewed for quality. A modified Delphi process was used to assess the literature and expert opinion for each topic, with 100% consensus being achieved on the statements and each recommendation. The consensus statements were then graded by the committee members using the United States Preventive Services Task Force grading of evidence guidelines. In addition to the consensus recommendations, a narrative overview of buprenorphine, including pharmacology and legal statutes, was performed.

RESULTS

Two core topics were identified for the development of recommendations with >75% consensus as the goal for consensus; however, the working group achieved 100% consensus on both topics. Specific topics included (1) providing recommendations to aid physicians in the management of patients receiving buprenorphine for MOUD in the perioperative setting and (2) providing recommendations to aid physicians in the initiation of buprenorphine in patients with suspected OUD in the perioperative setting.

CONCLUSIONS

To decrease the risk of OUD recurrence, buprenorphine should not be routinely discontinued in the perioperative setting. Buprenorphine can be initiated in untreated patients with OUD and acute pain in the perioperative setting to decrease the risk of opioid recurrence and death from overdose.

Literature review: Substance use screening and co-morbidity in medically hospitalized youth

OBJECTIVES

Pediatric and young adult patients frequently present to medical inpatient (MIP) units for treatment of substance use disorder (SUD). Given the risk of lifelong dependence and related complications in early life substance use (SU), a review of the literature is warranted.

METHODS

We conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) systematic review of literature published through April, 62,020, which examined incidence, screening, and complications of pediatric and young adult SU in the MIP setting.

RESULTS

8843 articles were screened, and 28 articles were included for final qualitative synthesis. The overall prevalence of SU-related discharge diagnoses ranged from 1.3% to 5% for patients aged 0 to 26 years. When compared to adult patients, nearly double the rate of co-morbid psychopathology was observed. Three studies utilized systematic screening tools, with the remainder relying on biologic screens and admission or discharge diagnoses.

CONCLUSIONS

The results of our review indicate that current screening practices for SU in the MIP clinical setting are subpar and likely result in an underestimation of incidence and morbidity due to limited use of systematic screening tools. Despite this, incidence of SU hospitalizations and related medical and psychiatric complications continue to rise.

Successful engagement in buprenorphine treatment among hospitalized patients with opioid use disorder and trauma

BACKGROUND

The opioid epidemic continues to cause significant morbidity and mortality. Although there are effective medications for opioid use disorder (OUD), a minority of patients receive these treatments. OUD is common among patients hospitalized for traumatic injury and hospitalization could be an opportunity to initiate medications and link to ongoing buprenorphine care.

METHODS

This retrospective cohort study based on electronic health record review included patients who were: (1) hospitalized between January 1, 2018 and June 30, 2019, (2) age ≥18 years, (3) seen by an Addiction Medicine Consult Service, and (4) initiated on buprenorphine with plans for continuation post-discharge. Descriptive statistics identified differences between trauma and non-trauma groups and regression analysis identified predictors of 30 day buprenorphine follow up.

RESULTS

Of 197 eligible patients, 60 (30.5 %) were hospitalized for traumatic injuries. Compared to non-trauma patients, trauma patients were younger, more likely to be employed, more likely to report using cannabis and tobacco, less likely to have recently injected drugs, and hospitalized longer. Among patients with follow-up data available (n = 147), 63.2 % of trauma patients were seen within 30 days, compared to 48.2 % of non-trauma patients (p = 0.16). There were no significant differences between the two groups with regards to urine drug test results or acute care utilization in the follow-up period.

CONCLUSIONS

Among hospitalized patients with OUD who initiate buprenorphine, those who were hospitalized for trauma were at least as likely to link to out-patient treatment. Trauma admissions represent an important opportunity for diagnosing and linking patients with OUD to buprenorphine treatment.

Navigation Services to Avoid Rehospitalization among Medical/Surgical Patients with Comorbid Substance Use Disorder: Rationale and Design of a Randomized Controlled Trial

Substance use disorders (SUDs) are associated with significant morbidity and mortality and contribute to inefficient use of healthcare services. Hospitalized medical/surgical patients with comorbid SUD are at elevated risk of hospital readmission and poor outcomes. Thus, effective interventions are needed to help such patients during hospitalization and post-discharge. This article reports the rationale, methodological design, and progress to date on a randomized trial comparing the effectiveness of Navigation Services to Avoid Rehospitalization (NavSTAR) vs Treatmentas-Usual (TAU) for hospital medical/surgical patients with comorbid SUD (N = 400). Applying Andersen’s theoretical model of health service utilization, NavSTAR employed Patient Navigation and motivational interventions to promote entry into SUD treatment, facilitate adherence to recommendations for medical follow-up and self-care, address basic needs, and prevent the recurrent use of hospital services. As part of the NavSTAR service model, Patient Navigators embedded within the SUD consultation service at a large urban hospital delivered patient-centered, proactive navigation and motivational services initiated during the hospital stay and continued for up to 3 months post-discharge. Participants randomized to TAU received usual care from the hospital and the SUD consultation service, which included referral to SUD treatment but no continued contact post-hospital discharge. Hospital service utilization will be determined via review of electronic health records and the regional Health Information Exchange. Participants were assessed at baseline and again at 3-, 6-, and 12-month follow-up on various measures of healthcare utilization, substance use, and functioning. The primary outcome of interest is time-to-rehospitalization through 12 months. In addition, a range of secondary outcomes spanning the medical and SUD service areas will be assessed. The study will include a health economic evaluation of NavSTAR. If NavSTAR proves to be effective and cost-effective in this high-risk patient group, it would have important implications for addressing the needs of hospital patients with comorbid SUD, designing hospital discharge planning services, informing cost containment initiatives, and improving public health.

Clinical and Sociobehavioral Prediction Model of 30-Day Hospital Readmissions Among People With HIV and Substance Use Disorder: Beyond Electronic Health Record Data

BACKGROUND

Under the Affordable Care Act, hospitals receive reduced reimbursements for excessive 30-day readmissions. However, the Centers for Medicare and Medicaid Services does not consider social and behavioral variables in expected readmission rate calculations, which may unfairly penalize systems caring for socially disadvantaged patients, including patients with HIV.

SETTING

Randomized controlled trial of patient navigation with or without financial incentives in HIV-positive substance users recruited from the inpatient setting at 11 US hospitals.

METHODS

External validation of an existing 30-day readmission prediction model, using variables available in the electronic health record (EHR-only model), in a new multicenter cohort of HIV-positive substance users was assessed by C-statistic and Hosmer-Lemeshow testing. A second model evaluated sociobehavioral factors in improving the prediction model (EHR-plus model) using multivariable regression and C-statistic with cross-validation.

RESULTS

The mean age of the cohort was 44.1 years, and participants were predominantly males (67.4%), non-white (88.0%), and poor (62.8%, <$20,000/year). Overall, 17.5% individuals had a hospital readmission within 30 days of initial hospital discharge. The EHR-only model resulted in a C-statistic of 0.65 (95% confidence interval: 0.60 to 0.70). Inclusion of additional sociobehavioral variables, food insecurity and readiness for substance use treatment, in the EHR-plus model resulted in a C-statistic of 0.74 (0.71 after cross-validation, 95% confidence interval: 0.64 to 0.77).

CONCLUSIONS

Incorporation of detailed social and behavioral variables substantially improved the performance of a 30-day readmission prediction model for hospitalized HIV-positive substance users. Our findings highlight the importance of social determinants in readmission risk and the need to ask about, adjust for, and address them.

In-hospital illicit drug use, substance use disorders, and acceptance of residential treatment in a prospective pilot needs assessment of hospitalized adults with severe infections from injecting drugs

OBJECTIVE

To conduct a pilot needs assessment of underlying substance use disorders (SUD), motivation for SUD treatment, and willingness to enter residential SUD treatment in hospitalized adults who inject drugs with complex infections requiring intravenous (IV) antibiotics, and to assess the presence of in-hospital illicit substance use.

PATIENTS AND METHODS

From March 8, 2016 through August 25, 2016 hospitalized, English-speaking, adult patients not currently in SUD treatment with a history of injection drug use and a current infection requiring treatment with IV antibiotics, were prospectively enrolled. Participants were followed weekly during the hospitalization and for 60 days after discharge via interview and medical record review.

RESULTS

Of the 42 participants, 8 (19.0%) accepted discharge to residential SUD treatment, 16 (38.0%) completed at least one follow-up research visit after hospital discharge, and 3 (7.1%) died during the 5-month study period. The majority (33; 78%) were hospitalized with endocarditis, and 37 (88.0%) had an opioid use disorder (DSM-5). Mean days of self-reported IV opioid use in the 30 days before hospitalization compared to 30 days after discharge decreased significantly (16.5 to 1.5, P = .001) despite not receiving SUD treatment. Illicit in-hospital drug use was identified in 17 (40.5%) participants, with opioids most commonly detected.

CONCLUSION

Hospitalization is a 'reachable moment' and critical opportunity to initiate evidence-based treatment for opioid use disorder. The ongoing in-hospital illicit drug use and high short-term mortality observed in this study contribute to the mandate to expand access to effective pharmacotherapy for opioid use disorder and integrate it into health care settings.

Planning and Designing the Improving Addiction Care Team (IMPACT) for Hospitalized Adults with Substance Use Disorder

People with substance use disorders (SUD) have high rates of hospitalization and readmission, long lengths of stay, and skyrocketing healthcare costs. Yet, models for improving care are extremely limited. We performed a needs assessment and then convened academic and community partners, including a hospital, community SUD organizations, and Medicaid accountable care organizations, to design a care model for medically complex hospitalized patients with SUD. Needs assessment showed that 58% to 67% of participants who reported active substance use said they were interested in cutting back or quitting. Many reported interest in medication for addiction treatment (MAT). Participants had high rates of costly readmissions and longer than expected length of stay. Community stakeholders identified long wait times and lack of resources for medically complex patients as key barriers. We developed the Improving Addiction Care Team (IMPACT), which includes an inpatient addiction medicine consultation service, rapid-access pathways to posthospital SUD treatment, and a medically enhanced residential care model that integrates antibiotic infusion and residential addiction care. We developed a business case and secured funding from Medicaid and hospital payers. IMPACT provides one pathway for hospitals, payers, and communities to collaboratively address the SUD epidemic.

"It's been an Experience, a Life Learning Experience": A Qualitative Study of Hospitalized Patients with Substance Use Disorders

BACKGROUND

Individuals with substance use disorders (SUD) have high rates of chronic illness and readmission, yet few are engaged in addiction treatment. Hospitalization may be a reachable moment for initiating and coordinating addiction care, but little is known about motivation for change in the inpatient setting.

OBJECTIVE

To explore the experiences of hospitalized adults with SUD and to better understand patient and system level factors impacting readiness for change.

DESIGN

We performed a qualitative study using individual interviews. The study was nested within a larger mixed-methods needs assessment.

PARTICIPANTS AND SETTING

Hospitalized adults admitted to medical or surgical units at an urban academic medical center who reported high-risk alcohol or drug use on AUDIT-C or single-item drug use screener.

APPROACH

We conducted a thematic analysis, using an inductive approach at a semantic level.

KEY RESULTS

Thirty-two patients participated. The mean age was 43 years; 75% were men, and 68% identified as white. Participants reported moderate to high-risk alcohol (39%), amphetamine (46%), and opioid (65%) use. Emergent themes highlight the influence of hospitalization at the patient, provider, and health system levels. Many patients experienced hospitalization as a wake-up call, where mortality was motivation for change and hospitalization disrupted substance use. However, many participants voiced complex narratives of social chaos, trauma, homelessness, and chronic pain. Participants valued providers who understood SUD and the importance of treatment choice. Patient experience suggests the importance of peers in the hospital setting, access to medication-assisted treatment, and coordinated care post-discharge.

CONCLUSIONS

This study supports that hospitalization offers an opportunity to initiate and coordinate addiction care, and provides insights into patient, provider, and health system factors which can leverage the reachability of this moment.

Non-fatal overdose as a risk factor for subsequent fatal overdose among people who inject drugs

OBJECTIVES

To examine the relationship between non-fatal overdose and risk of subsequent fatal overdose.

METHODS

We assessed risk factors for overdose death among two prospective cohorts of persons who inject drugs (PWID) in Vancouver, Canada. Extended Cox regression was used to examine if reports of non-fatal overdose were associated with the time to fatal overdose while adjusting for other behavioral, social and structural confounders.

RESULTS

Between May, 1996 and December, 2011, 2317 individuals were followed for a median of 60.8 months. In total, 134 fatal overdose deaths were identified for an incidence density of 8.94 (95% confidence interval [CI]: 7.55-10.59) deaths per 1000 person-years. During the study period there were 1795 reports of non-fatal overdose. In a multivariate model, recent non-fatal overdose was independently associated with the time to overdose mortality (adjusted hazard ratio [AHR]=1.95; 95% CI: 1.17-3.27). As well, there was a dose response effect of increasing cumulative reports of non-fatal overdose on subsequent fatal overdose.

CONCLUSION

Reports of recent non-fatal overdose were independently associated with subsequent overdose mortality in a dose-response relationship. These findings suggest that individuals reporting recent non-fatal overdose should be engaged with intensive overdose prevention interventions.

Propensity to Succeed: Prioritizing Individuals Most Likely to Benefit from Care Coordination

The objective was to develop a propensity to succeed (PTS) process for prioritizing outreach to individuals with Medicare Supplement (ie, Medigap) plans who qualified for a high-risk case management (HRCM) program. Demographic, socioeconomic, health status, and local health care supply data from previous HRCM program participants and nonparticipants were obtained from Medigap membership and health care claims data and public data sources. Three logistic regression models were estimated to find members with higher probabilities of engaging in the HRCM program, receiving high quality of care once engaged, and incurring enough monetary savings related to program participation to more than offset program costs. The logistic regression model intercepts and coefficients yielded the information required to build predictive models that were then applied to generate predicted probabilities of program engagement, high quality of care, and cost savings a priori for different members who later qualified for the HRCM program. Predicted probabilities from the engagement and cost models were then standardized and combined to obtain an overall PTS score, which was sorted from highest to lowest and used to prioritize outreach efforts to those newly eligible for the HRCM program. The validity of the predictive models also was estimated. The PTS models for engagement and financial savings were statistically valid. The combined PTS score based on those 2 components helped prioritize outreach to individuals who qualified for the HRCM program. Using PTS models may help increase program engagement and financial success of care coordination programs.

Thai men's experiences of alcohol addiction and treatment

BACKGROUND

Men are overrepresented with regard to alcohol addiction and in terms of alcohol treatment worldwide. In Thailand, alcohol consumption continues to rise, but few of those afflicted with alcohol addiction attend alcohol treatment programs, even though there is universal care for all. No comprehensive studies have been done on men's experiences with addiction and alcohol treatment programs in Thailand.

OBJECTIVE

The aim of this study was to explore men's experiences in terms of the 'pros and cons of alcohol consumption' in order to identify the barriers that exist for Thai men with regard to alcohol addiction and the decision to stop drinking.

DESIGN

Purposive sampling was applied in the process of recruiting participants at an alcohol clinic in a hospital in Thailand. Thirteen men with alcohol addiction (aged 32-49 years) were willing to participate and were interviewed in thematic interviews. The analysis of the data was done with descriptive phenomenology.

RESULTS

Through men's descriptions, three clusters of experiences were found that were 'mending the body', 'drinking as payoff and doping related to work', and 'alcohol becoming a best friend' as ways of describing the development of addiction.

CONCLUSIONS

The results highlight the importance of addressing concepts of masculinity and related hegemonic ideas in order to decrease the influence of the barriers that exist for Thai men with alcohol addiction with regard to entering treatment and to stop drinking.

Days of heroin use predict poor self-reported health in hospitalized heroin users

This study examined associations between substance use behaviors and self-reported health among hospitalized heroin users. Of the 112 participants, 53 (47%) reported good or better health. In multivariable logistic regression models, each day of heroin use in the last month was associated with an 8% lower odds of reporting health as good or better (OR=.92; 95% CI 0.87, 0.97, p<.05). Cocaine, cannabis, cigarettes, alcohol use, unintentional overdose, nor injection drug use was associated with health status.

A latent class approach to treatment readiness corresponds to a transtheoretical ("Stages of Change") model

Motivation for treatment among people with substance use problems is an important aspect of treatment success. Models for treatment motivation are widely debated. Latent Class Analysis can help to demonstrate the appropriateness of available models. The current study utilizes Latent Class Analysis to analyze treatment readiness statements as they relate to the reduction or cessation of marijuana, cocaine, and opioid use among 539 cocaine and opioid users recruited from the community of Baltimore, MD, USA. Participants completed an in-person structured interview including demographic questions, a treatment readiness questionnaire with items on Intention to Stop Use (ISU) and Problem Recognition (PR), current substance abuse treatment utilization, and urinalysis testing for marijuana, cocaine, and heroin. Latent class models were fit to the treatment readiness questionnaire. A four-class model provided the best fit with one class low on both ISU and PR ("Pre-contemplative"), a second class low on ISU but high on PR ("Contemplative"), a third class high on both ("Preparation/Action"), and a final class high on ISU but low on PR ("Post-Action"). Compared to the "Contemplative" class, the "Pre-contemplative" class was significantly more likely to be positive for marijuana, and the "Post-Action" class was significantly less likely to be positive for opioids. The "Preparation/Action" class was significantly more likely to be in treatment. With the exception of the "Post-Action" class, the analysis appears similar to the "Stages of Change" model and suggests that problem recognition and intention to stop use are important domains in the model. However, further longitudinal research is needed to assess predictive validity of model.

The health encounter as a treatable moment for homeless substance-using adults: the role of homelessness, health seeking behavior, readiness for behavior change and motivation for treatment

Substance-using homeless persons frequent emergency departments and hospitals often. However, little is known about how homelessness affects when they seek care and their motivation for substance abuse treatment (SAT). We surveyed homeless (N=266) and non-homeless (N=104) substance-using adults sequentially admitted to an urban hospital medicine service, comparing demographics, readiness for change (URICA), and motivating reasons for SAT. Homeless respondents were more likely to be younger, uninsured, have hepatitis B/C, and <12th grade education. The majority in both groups were in either a precontemplative or contemplative stage of change, although more homeless respondents were in an action stage. They also had similar motivating reasons for wanting SAT, although being homeless was an additional motivator for the majority of homeless respondents. Almost half reported that being homeless caused them to delay seeking health care; paradoxically those citing physical health as a SAT motivator were 3.4 times more likely to have delayed care. While acutely ill homeless persons were at least as motivated for SAT, these data suggest the challenge is getting them to care in a timely manner and tailoring interventions during the care episode to avail of this motivation.

The effect of integrated medical-substance abuse treatment during an acute illness on subsequent health services utilization

BACKGROUND

The acute care hospital provides a context for engaging difficult to reach patients in substance abuse treatment (SAT); however, little is known regarding the effects of such engagement on subsequent health services utilization. We examined whether a structured day hospital (DH) intervention integrating SAT and medical care during an acute medical hospitalization would reduce subsequent emergency department (ED) use and rehospitalization compared with a control group receiving usual medical care and referral to intensive outpatient SAT.

METHODS

Between October 2001 and June 2002, we enrolled 390 hospitalized substance using patients in a nonrandomized clinical trial. Once stabilized, patients were assigned to either the DH intervention (n = 63) or usual care control group (n = 327). Baseline interview and chart review collected data on demographics, substance use, and acute and chronic medical conditions. Subsequent chart review collected data on ED, hospital and ambulatory care utilization in the 6 months pre-enrollment and 6 months postdischarge. Univariate and multiple logistic regression methods were used to assess the independent effects of the DH intervention on postdischarge health care utilization.

RESULTS

Overall 25%, 48%, and 42% reported > or =3 ED episodes, > or =1 rehospitalization, and > or =1 ambulatory care visit during the postdischarge period. Subjects who completed the DH intervention were significantly less likely to have > or =3 ED episodes (AOR = 0.27; 95% CI, 0.08-0.89) and more likely to have > or =1 ambulatory care visit (AOR = 4.05; 95% CI, 1.44-11.37) than the usual care group. No similarly beneficial effects were seen for patients who initiated but did not complete the DH intervention.

CONCLUSIONS

: A DH model that engages acutely ill substance using patients in integrated medical and substance abuse treatment can positively influence subsequent health care seeking behavior.

Where do people go when they first become homeless? A survey of homeless adults in the USA

The longer a person is homeless, the more likely he or she is to experience poor health and be placed at higher risk for premature death. This makes interventions early in one's homelessness an important prevention strategy. However, little is known about where someone goes for help when they first become homeless and how well those sites are prepared to address the multitude of issues facing a homeless person. In order to address this question, we conducted a cross-sectional community-based survey in two US cities in 1997 using population proportionate sampling of homeless persons identified at 91 sites to identify 'first-stop' access sites and reasons for seeking help at those sites. A total of 230 persons participated in the face-to-face interview (93% response rate). From a list of 20 possible 'first-stop' sites, 105 (45.7%) reported going to a soup kitchen, 71 (30.9%) went to a welfare office, 64 (27.8%) sought admission to a detoxification centre, 60 (26.1%) met with a homeless outreach team, 57 (24.8%) went to a family member, and 54 (23.5%) went to an emergency room. Individuals with a chronic medical or mental health condition were significantly more likely to access a healthcare site (medical: 62.6% vs. 47.6%, P = 0.02; mental health: 62.4% vs. 38.8%, P < 0.01) or social service agency (medical: 64.0% vs. 43.3%, P = 0.02; mental health: 59.1% vs. 40.7%, P < 0.01). Those persons reporting a need for alcohol treatment were significantly more likely to first go to a healthcare site (46.4% vs. 29.1%, P < 0.01) and those with alcohol abuse/dependence were less likely to seek help from family or friends (66.7% vs. 81.9%, P < 0.01). Most respondents sought assistance for concerns directly associated with an immediate need as opposed to seeking care for issues causing their actual homelessness. These findings suggest the need to expand and integrate the availability of services at 'first-stop' access sites that facilitate early exits from homelessness.

Trends in rates of hospitalization with a diagnosis of substance abuse among reproductive-age women, 1998 to 2003

OBJECTIVE

To describe trends in hospitalizations with a diagnosis of substance abuse among reproductive-age women from 1998-2003.

METHODS

Data were obtained from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample. Hospitalizations with a diagnosis of substance abuse were categorized into subgroups by age, primary expected payer, substance-specific diagnoses, concomitance, and hospital location. Trends in hospitalization rates per 100,000 women aged 15-44 were tested using a weighted least-squares method.

RESULTS

From 1998-2003, there was no change in the overall rate of hospitalization with a diagnosis of substance abuse among women aged 15-44. Alcohol abuse was the most common substance-specific diagnosis. The rate of hospitalization with a diagnosis of cocaine abuse decreased 22%; for a diagnosis of cannabis abuse, the rate increased 35%. The rate of hospitalization with a diagnosis of amphetamine abuse doubled from 1998-2003. Among women aged 15-24, the rate of hospitalization with a diagnosis of substance abuse increased 23%.

CONCLUSION

Although we did not observe a change in the overall rate of substance-abuse hospitalization among reproductive-age women, there were dramatic changes in the rate of substance-specific diagnoses. These data may be used to quantify emerging trends in substance abuse and promote the use of hospital-based interventions.

Factors identifying high-frequency and low-frequency health service utilization among substance-using adults

Understanding why substance-using patients seek care at emergency departments (EDs) and who utilizes such service at high rates is important in tailoring and targeting interventions. We conducted a retrospective/prospective cohort study of 326 medically ill substance-using adults to identify factors associated with 12-month high-frequency utilization of ambulatory care, ED, and inpatient medical care. The majority were actively using heroin (74.6%), cocaine (62.4%), and alcohol (54.4%); 94.8% had a chronic medical condition; and 53.8% reported a chronic mental health condition. High-frequency use of ED (> or = 3 visits) was independently associated with being female (adjusted odds ratio [AOR] = 1.88; 95% confidence interval [95% CI] = 1.12, 3.17), being African American (AOR = 2.36; 95% CI = 1.30, 4.29), being homeless (AOR = 2.07; 95% CI = 1.08, 3.96), a history of > 1 substance abuse treatment episode (AOR = 4.10; 95% CI = 3.28, 10.87), and > or = 1 ambulatory care visit (AOR = 8.94; 95% CI = 3.28, 24.41). However, the combination of having certain chronic conditions (seizure disorder, hepatitis B, and hepatitis C) and accessing ambulatory care was protective against high-frequency use of ED. In contrast, high-frequency use of ambulatory care (> or = 3 visits) was independently associated with having insurance (Medicare/Medicaid: AOR = 2.39; 95% CI = 1.31, 4.69), having HIV/AIDS (AOR = 3.15; 95% CI = 1.70, 5.85), and receiving substance abuse treatment during the study period (AOR = 3.58; 95% CI = 1.61, 7.98) Efforts to redirect medical care to more subacute settings will likely require both capacity building and addressing a client's underlying needs, including homelessness, access to substance abuse treatment, and chronic disease management.
