Opioid Use Disorder Among Hospitalized Older Adults: Prevalence, Characteristics, and Discharge Status

Readmissions and Mortality After "Before Medically Advised" Hospital Discharges Among Medicare Beneficiaries with Opioid Use Disorder

BACKGROUND

"Before medically advised" (BMA) discharges are rising among hospitalized people with opioid use disorder (OUD) and associated with worse outcomes. However, little is known about BMA discharge among the growing share of U.S. Medicare beneficiaries with OUD.

OBJECTIVE

To examine patterns of hospital readmissions and mortality by discharge type among Medicare beneficiaries with OUD.

DESIGN

Retrospective cohort study using 100% national inpatient Medicare data from 2016 to 2019.

PARTICIPANTS

Fee-for-service Medicare beneficiaries age 18 + with an OUD diagnosis during an inpatient hospitalization. Discharge types were classified as BMA, home, skilled nursing facilities (SNFs), or non-SNF institutional settings.

MAIN MEASURES

Using linear probability models adjusted for demographic, clinical, and hospital covariates, we examined 30-day unplanned all-cause readmission and mortality probabilities across discharge types. Secondarily, we assessed time until readmission and mortality, repeated readmissions or BMA discharges, readmission to different hospitals, and primary readmission diagnoses.

KEY RESULTS

Among 339,712 hospitalized Medicare beneficiaries with OUD, 13,997 (4.1%) were discharged BMA. Within 30 days, 25.5% of patients discharged BMA were readmitted and 2.5% died. Compared to other discharges, readmissions after BMA discharge occurred sooner (9.9 vs. 12.8-13.3 days), and were more likely to happen repeatedly (23.4% vs. 13.1-18.3%), end in another BMA discharge (20.9% vs. 0.8-3.5%), and take place at different hospitals (50.8% vs. 29.8-37.6%). Adjusted readmission probabilities for BMA discharges were 7.1 percentage points (pp) higher than home discharges and 6.0-8.9 pp higher than SNF and non-SNF discharges (all p < 0.001). Adjusted mortality probabilities for BMA discharges were 0.7 pp higher than home discharges, but 0.8-1.9 pp lower than SNF and non-SNF discharges (all p < 0.001).

CONCLUSIONS

BMA discharge among Medicare beneficiaries with OUD is associated with fragmented patterns of post-discharge care, and increased readmissions and deaths relative to home discharges. Efforts are needed to address the drivers and consequences of BMA discharge among individuals with OUD in Medicare.

A Climate of Stigma, Uncertainty, and Distrust: Stakeholder Perception of Barriers to SNF Placement for Patients with Opioid Use Disorder Treated with Methadone

BACKGROUND

Patients with opioid use disorder (OUD), especially those treated with methadone, face significant challenges to placement in a skilled nursing facility (SNF). Efforts to address this via legal actions have not resulted in improved access.

OBJECTIVE

To understand regulatory and non-regulatory factors that impact SNF placement of patients with OUD treated with methadone.

DESIGN

Observational qualitative study.

PARTICIPANTS

Stakeholders in the hospital-to-SNF referral process as well as those with specific expertise related to OUD.

APPROACH

Open-ended, semi-structured interviews.

RESULTS

Interviews with 15 participants identified three key themes that function together in addition to logistic and financial barriers: (1) stigma and perception of risk, (2) uncertain regulatory environment, and (3) distrust between responsible entities. Fundamentally, many SNFs do not feel they can provide necessary care related to OUD and methadone. They tend to be disinclined to care for patients with OUD and express concerns about perceived risks such as overdose, violence, or discomfort to other residents. SNFs are also very motivated to avoid regulatory citations and fines related to OUD or methadone. Since confusion and misinformation about relevant policies and procedures is common, many opt to decline these patients. Compounding these challenges, entities responsible for coordinating care demonstrate poor communication and lack of transparency with each other. Referral and declination information sent between hospitals and SNFs is often considered to be incomplete or incorrect, and many hospitals have stopped referring patients with OUD treated with methadone to SNFs altogether. Regulatory bodies are often feared by healthcare providers and administrators and interaction is avoided. Finally, legal oversight representatives report that they do not receive sufficient information to properly investigate concerns.

CONCLUSION

This study identifies the climate of stigma, uncertainty, and distrust between responsible entities that stymies improvement efforts. Creation of meaningful reform must address each of these areas.

Disparities in Access to Highly Rated Skilled Nursing Facilities among Medicare Beneficiaries with Opioid Use Disorder

OBJECTIVES

To investigate disparities in admissions to highly rated skilled nursing facilities (SNFs) between Medicare beneficiaries with and without opioid use disorder (OUD).

DESIGN

Nationwide, retrospective observational cohort.

SETTING AND PARTICIPANTS

Medicare Fee-for-Service beneficiaries aged ≥18 years admitted to SNFs following hospitalization during 2016-2020 (n = 30,922 with OUD and n = 137,454 without OUD).

METHODS

Data used were 100% Medicare inpatient claims, nursing home administrative databases, and Nursing Home Compare. We identified hospitalized patients with and without OUD and matched them on age, sex, Part D low-income subsidy (LIS), and residential county. We compared the overall and component (quality, staffing, and health inspections) star ratings of SNFs that beneficiaries entered. Beneficiary-level regression models were conducted adjusting for race and ethnicity, Medicare-Medicaid dual status, comorbidity score, hospital length of stay, and state and year fixed effects.

RESULTS

The overall study sample had a mean (SD) age of 71.4 (11.4) years, 63.9% were female, and 57.4% had LIS. Among beneficiaries with OUD, 50.3% entered SNFs with above-average (4 or 5) overall rating compared with 51.3% among those without OUD. Distributions of above-average ratings among beneficiaries with and without OUD were as follows: 63.9% vs 62.2% for quality, 32.8% vs 34.9% for health inspections, and 46.2% vs 45.0% for staffing, respectively. Adjusted regression models indicated that beneficiaries with OUD were less likely to be admitted to facilities with above-average overall (OR 0.90, 95% CI 0.87-0.92), health inspection (OR 0.90, 95% CI 0.88-0.93), and staffing (OR 0.91, 95% CI 0.89-0.94) ratings compared with beneficiaries without OUD, whereas quality (OR 0.98, 95% CI 0.95-1.01) ratings did not differ.

CONCLUSIONS AND IMPLICATIONS

Despite mixed results on component ratings, our findings suggest a concerning disparity in the overall quality of SNFs admitting Medicare beneficiaries with OUD. Enhancing equitable access to high-quality SNF care for individuals with OUD is imperative amid rising demand and legal protections under the American Disabilities Act.

The association between opioid use disorder and skilled nursing facility acceptances: A multicenter retrospective cohort study

BACKGROUND

Prior single-hospital studies have documented barriers to acceptance that hospitalized patients with opioid use disorder (OUD) face when referred to skilled nursing facilities (SNFs).

OBJECTIVE

To examine the impact of OUD on the number of SNF referrals and the proportion of referrals accepted.

DESIGN, SETTINGS, AND PARTICIPANTS

A retrospective cohort study of hospitalizations with SNF referrals in 2019 at two academic hospitals in Baltimore, MD.

EXPOSURE

OUD status was determined by receipt of medications for OUD during admission, upon discharge, or the presence of a diagnosis code for OUD.

KEY RESULTS

The cohort included 6043 hospitalizations (5440 hospitalizations of patients without OUD and 603 hospitalizations of patients with OUD). Hospitalizations of patients with OUD had more SNF referrals sent (8.9 vs. 5.6, p < .001), had a lower proportion of SNF referrals accepted (31.3% vs. 46.9%, p < .001), and were less likely to be discharged to an SNF (65.6% vs. 70.3%, p = .003). The effect of OUD status on the number of SNF referrals and the proportion of referrals accepted remained significant in multivariable analyses. Our subanalysis showed that reduced acceptances were driven by the hospitalizations of patients discharged without medications for OUD and those receiving methadone. Hospitalizations of patients discharged on buprenorphine were accepted at the same rates as hospitalizations of patients without OUD.

CONCLUSIONS

This multicenter retrospective cohort study found that hospitalizations of patients with OUD had more SNF referrals sent and fewer referrals accepted. Further work is needed to address the limited discharge options for patients with OUD.

Perspectives on Admissions and Care for Residents With Opioid Use Disorder in Skilled Nursing Facilities

Importance

Skilled nursing facilities (SNFs) are being referred more individuals with opioid use disorder (OUD), even when their medical needs are not directly associated with OUD.

Objective

To characterize factors that influence SNF admission for individuals with OUD and identify strategies for providing medications for OUD (MOUD) in SNFs.

Design, Setting, and Participants

In this semistructured qualitative study, interviews were conducted with SNF administrators from 27 SNFs in Rhode Island from November 5, 2021, to April 27, 2022. Data analysis occurred from August 22, 2022, to May 31, 2023.

Main Outcomes and Measures

Themes and subthemes on administrator perspectives on admissions and care for people with OUD in SNFs. Audio interviews were transcribed, coded, and analyzed using codebook thematic analysis and guided by community-engaged and participatory research principles.

Results

The study included 29 participants representing 27 SNFs in Rhode Island. Participant roles were administrators (17 participants [59%]), directors of nursing (6 participants [21%]), directors of admissions (5 participants [17%]), and unit managers (1 participant [3%]). Participants described active substance use, Medicaid insurance, housing instability, and younger age as potential barriers to SNF admission for individuals with OUD. The lack of formal guidelines for OUD management, staff shortages, facility liability, state regulations, and skills and training deficits among staff were cited among challenges of effectively meeting the needs of residents with OUD. Many participants reported inadequate institutional capacity as a source of negative outcomes for people with OUD yet expressed their concerns by characterizing individuals with OUD as potentially violent, nonadherent, or likely to bring undesirable elements into facilities. Participants also shared strategies they used to better serve residents with OUD, including providing transportation to support group meetings in the community, delivery in advance of resident arrival of predosed methadone, and telemedicine through the state's hotline to prescribe buprenorphine.

Conclusions and Relevance

In this qualitative study of administrator perspectives about admissions and care for individuals with OUD in SNFs, gaps in institutional capacity overlapped with stigmatizing beliefs about OUD; such beliefs perpetuate discrimination of individuals with OUD. Adequate SNF funding and staffing combined with OUD-specific interventions (eg, antistigma training, community partnerships for MOUD and recovery support) could incentivize SNFs to serve individuals with OUD and facilitate OUD care consistent with practice guidelines.

Barriers to Care for Nursing Home Residents With Substance Use Disorders: A Qualitative Study

OBJECTIVES

Over the past decade, the numbers of older adults with opioid and substance use disorders (OUD/SUD) have increased. As this population enters nursing homes (NHs) in increasing numbers, it is crucial to consider their capacity to manage issues related to OUD/SUD. This study aimed to examine current NH protocols for care coordination of residents with OUD/SUD as well as facility-related barriers to providing care to this vulnerable population within the NH.

METHODS

Twenty-four semistructured interviews were conducted with NH staff including directors of nursing, administrators, nurses, and physicians in July 2020. Staff were recruited from 11 different post-acute care and long-term care facilities located in urban and suburban communities of Chicago. Interviews were conducted virtually (via teleconference platform or by telephone) and subsequently coded using ATLAS.ti 8 (ATLAS.ti Scientific Software Development GmbH, Berlin, Germany) using constant comparative method.

RESULTS

Qualitative analyses identified 3 themes around NH barriers to care for residents with SUD/OUD: (1) staff preparedness, (2) staff perceptions of addiction, and (3) overall lack of resources. Results revealed a strong need for the development of consistent policies, as well as standardized, educational interventions for NH staff that target SUD/OUD management in this vulnerable population.

CONCLUSIONS

The evaluation and impact of persons with SUD/OUD entering NHs are an important topic that requires further study. More resources and staff training are necessary to ensure that residents with SUD/OUD have access to appropriate care within these settings.

Provider beliefs about the ideal design of an opioid deprescribing and substitution intervention for older adults

PURPOSE

Opportunities exist to meaningfully reduce suboptimal prescription opioid use among older adults. Deprescribing is one possible approach to reducing suboptimal use. Appropriate interventions should outline how to carefully taper opioids, closely monitor adverse events, substitute viable alternative and affordable nonopioid pain treatments, and initiate medications for opioid use disorder to properly manage use disorders, as needed. We sought to document and understand provider perceptions to begin developing effective and safe opioid deprescribing interventions.

METHODS

We conducted 3 semistructured focus groups that covered topics such as participant perspectives on opioid deprescribing in older adults, how to design an ideal intervention, and how to identify potential barriers or facilitators in implementing an intervention. Focus group transcripts were double coded and qualitatively analyzed to identify overarching themes.

RESULTS

Healthcare providers (n = 17), including physicians, pharmacists, nurses, social workers, and administrative staff, participated in 3 focus groups. We identified 4 key themes: (1) involve pharmacists in deprescribing and empower them as leaders of an opioid deprescribing service; (2) ensure tight integration and close collaboration throughout the deprescribing process from the inpatient to outpatient settings; (3) more expansive inclusion criteria than age alone; and (4) provision of access to alternative pharmacological and nonpharmacological pain management modalities to patients.

CONCLUSION

Our findings, which highlight various healthcare provider beliefs about opioid deprescribing interventions, are expected to serve as a framework for other organizations to develop and implement interventions. Future studies should incorporate patients' and family caregivers' perspectives.

OUD MEETS: A novel program to increase initiation of medications for opioid use disorder and improve outcomes for hospitalized patients being discharged to skilled nursing facilities

INTRODUCTION

Rates of hospitalizations from medical complications of opioid use disorder (OUD) are rising and many of these patients require post-acute care at skilled nursing facilities (SNFs). However, access to medication for OUD (MOUD) at SNFs remains low and patients with OUD have high rates of patient-directed discharge (PDD) and hospital readmissions.

METHODS

Opioid Use Disorder Medical Patient Engagement, Enrollment in treatment and Transitional Supports (OUD MEETS) program was a clinical pilot designed to increase initiation of buprenorphine and methadone for hospitalized patients with OUD requiring post-acute care. The program comprises a hospital partnership with two SNFs and two opioid treatment programs (OTPs) to improve recovery supports and access to MOUD for patients discharged to SNF.

RESULTS

Between August 2019 and August 2020, study staff approached 49 hospitalized patients with OUD for participation in OUD MEETS. Twenty-eight of 30 eligible patients enrolled in the program and initiated buprenorphine or methadone. Twenty-seven (96 %) enrolled patients successfully completed hospital treatment. Twenty-three (85 %) patients successfully completed medical treatment at SNF. Thirteen (46 %) enrolled patients had confirmed linkage to OUD treatment post-SNF. One patient left the hospital (4 %) and four patients left SNF (15 %) via PDD.

CONCLUSION

OUD MEETS demonstrates feasibility of hospital, SNF, and OTP partnership to integrate MOUD treatment into SNFs, with high rates of completion of medical treatment and low rates of PDD. Future research should find sustainable ways to improve access to MOUD at post-acute care facilities, including through regulatory and policy changes.

Discharge locations after hospitalizations involving opioid use disorder among medicare beneficiaries

BACKGROUND

Hospitalizations involving opioid use disorder (OUD) have been increasing among Medicare beneficiaries of all ages. With rising OUD-related acute care use comes the need to understand where post-acute care is provided and the capacities for OUD treatment in those settings. Our objective was to describe hospitalized Medicare beneficiaries with OUD, their post-acute care locations, and all-cause mortality and readmissions stratified by post-acute care location.

METHODS

We conducted a retrospective cohort study of acute hospitalizations using 2016-2018 Medicare Provider Analysis and Review (MedPAR) files linked to Medicare enrollment data and the Residential History File (RHF) for 100% of Medicare fee-for-service beneficiaries. The RHF which provides a person-level chronological history of health service utilization and locations of care was used to identify hospital discharge locations. We used ICD-10 codes for opioid dependence or "abuse" to identify OUD diagnoses from the MedPAR file. We conducted logistic regression to identify factors associated with discharge to an institutional setting versus home adjusting for demographics, comorbidities, and hospital stay characteristics.

RESULTS

Our analysis included 459,763 hospitalized patients with OUD. Of these, patients aged < 65 years and those dually enrolled in Medicaid comprised the majority (59.1%). OUD and opioid overdose were primary diagnoses in 14.3% and 6.2% of analyzed hospitalizations, respectively. We found that 70.3% of hospitalized patients with OUD were discharged home, 15.8% to a skilled nursing facility (SNF), 9.6% to a non-SNF institutional facility, 2.5% home with home health services, and 1.8% died in-hospital. Within 30 days of hospital discharge, rates of readmissions and mortality were 29.7% and 3.9%; respectively, with wide variation across post-acute locations. Factors associated with greater odds of discharge to institutional settings were older age, female sex, non-Hispanic White race and ethnicity, dual enrollment, longer hospital stay, more comorbidities, intensive care use, surgery, and primary diagnoses including opioid or other drug overdoses, fractures, and septicemia.

CONCLUSIONS

More than one-quarter (25.8%) of hospitalized Medicare beneficiaries with OUD received post-acute care in a setting other than home. High rates and wide variation in all-cause readmissions and mortality within 30 days post-discharge emphasize the need for improved post-acute care for people with OUD.

Under-representation of key demographic groups in opioid use disorder trials

Background

The extent to which clinical trials of medications for opioid use disorder (MOUD) are representative or not is unknown. Some patient characteristics modify MOUD effectiveness; if these same characteristics differ in distribution between the trial population and usual-care population, this could contribute to lack of generalizability-a discrepancy between trial and usual-care effectiveness. Our objective was to identify interpretable, multidimensional subgroups who were prescribed MOUD in substance use treatment programs in the US but who were not represented or under-represented by clinical trial participants.

Methods

This was a secondary descriptive analysis of trial and real-world data. The trial data included twenty-seven US opioid treatment programs in the National Drug Abuse Treatment Clinical Trials Network, N = 2,199 patients. The real-world data included US substance use treatment programs that receive public funding, N = 740,015 patients. We characterized real-world patient populations who were non-represented and under-represented in the trial data in terms of sociodemographic and clinical characteristics that could modify MOUD effectiveness.

Results

We found that 10.7% of MOUD patients in TEDS-A were not represented in the three clinical trials. As expected, pregnant MOUD patients (n = 19,490) were not represented. Excluding pregnancy, education and marital status from the characteristics, 2.6% of MOUD patients were not represented. Patients aged 65 years and older (n = 11,204), and those 50-64 years who identified as other (non-White, non-Black, and non-Hispanic) race/ethnicity or multi-racial (n = 7,281) were under-represented.

Conclusions

Quantifying and characterizing non- or under-represented subgroups in trials can provide the data necessary to improve representation in future trials and address research-to-practice gaps.

Multimorbidity and Inpatient Utilization Among Older Adults with Opioid Use Disorder in New York City

BACKGROUND

Nationally, there is a sharp increase in older adults with opioid use disorder (OUD). However, we know little of the acute healthcare utilization patterns and medical comorbidities among this population.

OBJECTIVE

This study describes the prevalence of chronic conditions, patterns of inpatient utilization, and correlates of high inpatient utilization among older adults with OUD in New York City (NYC).

DESIGN

Retrospective longitudinal cohort study.

PARTICIPANTS

Patients aged ≥55 with OUD hospitalized in NYC in 2012 identified using data from New York State's Statewide Planning and Research Cooperative System (SPARCS).

MAIN MEASURES

The prevalence of comorbid substance use diagnoses, chronic medical disease, and mental illness was measured using admission diagnoses from the index hospitalization. We calculated the ICD-Coded Multimorbidity-Weighted Index (MWI-ICD) for each patient to measure multimorbidity. We followed the cohort through September 30, 2015 and the outcome was the number of rehospitalizations for inpatient services in NYC. We compared patient-level factors between patients with the highest use of inpatient services (≥7 rehospitalizations) during the study period to low utilizers. We used multiple logistic regression to examine possible correlates of high inpatient utilization.

KEY RESULTS

Of 3669 adults aged ≥55 with OUD with a hospitalization in 2012, 76.4% (n=2803) had a subsequent hospitalization and accounted for a total of 22,801 rehospitalizations during the study period. A total of 24.7% of the cohort (n=906) were considered high utilizers and had a higher prevalence of alcohol and cocaine-related diagnoses, congestive heart failure, diabetes, schizophrenia, and chronic obstructive pulmonary disease. Multivariable predictors of high utilization included being a Medicaid beneficiary (adjusted odds ratio [aOR]=1.70, 95% confidence interval [CI]=1.37-2.11), alcohol-related diagnoses (aOR=1.43, 95% CI: 1.21-1.69), and increasing comorbidity measured by MWI-ICD (highest MWI-ICD quartile: aOR=1.98, 95% CI=1.59-2.48).

CONCLUSIONS

Among older adults with OUD admitted to the hospital, multimorbidity is strongly associated with high inpatient utilization.

Late- and Typical-Onset Heroin Use Among Older Adults Seeking Treatment for Opioid Use Disorder

OBJECTIVE

Analyze 10-year trends in opioid use disorder with heroin (OUD-H) among older persons and to compare those with typical-onset (age <30 years) to those with late (age 30+) onset.

DESIGN

Naturalistic observation using the most recent (2008-2017) Treatment Episode Data Set-Admissions (TEDS-A).

SETTING

Admission records in TEDS-A come from all public and private U.S. programs for substance use disorder treatment receiving public funding.

PARTICIPANTS

U.S. adults aged 55 years and older entering treatment for the first time between 2008 and 2017 to treat OUD-H.

MEASUREMENTS

Admission trends, demographics, substance use history.

RESULTS

The number of older adults who entered treatment for OUD-H nearly tripled between 2007 and 2017. Compared to those with typical-onset (before age 30), those with late-onset heroin use were more likely to be white, female, more highly educated, and rural. Older adults with late-onset were more likely to be referred to treatment by an employer and less likely to be referred by the criminal justice system. Those with late-onset were more likely to use heroin more frequently but less likely to inject heroin than those with typical-onset. Those with typical onset were more likely to receive medication for addiction treatment than those with late-onset.

CONCLUSION

Late-onset heroin use is increasing among older U.S. adults. Research is needed to understand the unique needs of this population better. As this population grows, geriatric psychiatrists may be increasingly called upon to provide specialized care to people with late-onset OUD-H.
