Key Points
Question
Were new federal authorities to expand telehealth use for substance use disorder treatment and to facilitate provision of medications for opioid use disorder (MOUD) during the COVID-19 pandemic associated with a lower risk for fatal drug overdose among Medicare beneficiaries initiating a new episode of opioid use disorder (OUD)–related care?
Findings
In this cohort study of a prepandemic cohort comprising 105 162 beneficiaries and a pandemic cohort comprising 70 479 beneficiaries, receipt of OUD-related telehealth services and receipt of MOUD during the pandemic were associated with reduced odds for fatal drug overdose.
Meaning
This study found that emergency authorized telehealth expansion and MOUD provision during the COVID-19 pandemic were associated with lower odds of fatal drug overdose, demonstrating the potential benefits of continuing these services.
Abstract
Importance
Federal emergency authorities were invoked during the COVID-19 pandemic to expand clinical telehealth for opioid use disorder (OUD).
Objective
To examine the association of the receipt of telehealth services and medications for OUD (MOUD) with fatal drug overdoses before and during the pandemic.
Design, Setting, and Participants
This cohort study used exploratory longitudinal data from 2 cohorts (prepandemic cohort: September 1, 2018, to February 29, 2020; pandemic cohort: September 1, 2019, to February 28, 2021) of Medicare Fee-for-Service beneficiaries aged 18 years or older initiating an episode of OUD-related care using Medicare Fee-for-Service data from the Centers for Medicare & Medicaid Services and National Death Index data from the Centers for Disease Control and Prevention. Data analysis was performed from September 19 to October 17, 2022.
Exposures
Prepandemic vs pandemic cohort demographic, medical, substance use, and psychiatric characteristics.
Main Outcomes and Measures
Receipt of OUD-related telehealth services, receipt of MOUD, and fatal drug overdose.
Results
The prepandemic cohort comprised 105 162 beneficiaries (58.1% female; 67.6% aged 45-74 years). The pandemic cohort comprised 70 479 beneficiaries (57.1% female; 66.3% aged 45-74 years). The rate of all-cause mortality was higher in the pandemic cohort (99.9 per 1000 beneficiaries; 7041 deaths) than in the prepandemic cohort (76.8 per 1000; 8076 deaths) (P < .001). The rate of fatal drug overdoses was higher in the pandemic cohort (5.1 per 1000 beneficiaries; n = 358) than in the prepandemic cohort (3.7 per 1000; n = 391) (P < .001). The percentage of deaths due to a fatal drug overdose was similar in the prepandemic (4.8%) and pandemic (5.1%) cohorts (P = .49). In multivariable analysis of the pandemic cohort, receipt of OUD-related telehealth was associated with a significantly lower adjusted odds ratio (aOR) for fatal drug overdose (aOR, 0.67; 95% CI, 0.48-0.92) as was receipt of MOUD from opioid treatment programs (aOR, 0.41; 95% CI, 0.25-0.68) and receipt of buprenorphine in office-based settings (aOR, 0.62; 95% CI, 0.43-0.91) compared with those not receiving MOUD; receipt of extended-release naltrexone in office-based settings was not associated with lower odds for fatal drug overdose (aOR, 1.16; 95% CI, 0.41-3.26).
Conclusions and Relevance
This cohort study found that, among Medicare beneficiaries initiating OUD-related care during the COVID-19 pandemic, receipt of OUD-related telehealth services was associated with reduced risk for fatal drug overdose, as was receipt of MOUD from opioid treatment programs and receipt of buprenorphine in office-based settings. Strategies to expand provision of MOUD, increase retention in care, and address co-occurring physical and behavioral health conditions are needed.
This cohort study examines the association of the receipt of telehealth services and medications for opioid use disorder (OUD) with fatal drug overdoses before and during the pandemic.
Introduction
During the COVID-19 pandemic, federal actions were taken to facilitate access to care for individuals with opioid use disorder (OUD), including expanded telehealth, remote prescribing of buprenorphine, and expanded take-home doses of methadone from opioid treatment programs (OTPs).1,2,3,4,5,6
We previously used a longitudinal 2-cohort study design with Medicare Fee-for-Service (FFS) data from September 2018 to February 2021 to compare the use of telehealth services among Medicare beneficiaries initiating OUD-related care before and during the pandemic.7 Use of OUD-related telehealth services during the pandemic was associated with improved retention in use of medications for opioid use disorder (MOUD) and reduced risk for medically treated overdose.7 Examining fatal drug overdoses was not possible due to lack of linked Medicare and overdose death data at that time. With the recent availability of linked data through 2021, this follow-up study uses the same 2-cohort longitudinal design to examine the association of receipt of OUD-related telehealth services and MOUD with drug overdose deaths before and during the COVID-19 pandemic.
Methods
Multiple Centers for Medicare & Medicaid Services (CMS) data sources8,9 were used (eTable in Supplement 1). Drug overdose death data from the Centers for Disease Control and Prevention (CDC) National Death Index were linked to Medicare Beneficiary Summary Files. The full details of the cohort design have been provided elsewhere.7 In brief, we constructed 2 mutually exclusive cohorts of Medicare FFS beneficiaries aged 18 years or older with OUD, both before and during the pandemic, consisting of individuals starting new (index) episodes of OUD-related care. Individuals already receiving OUD-related services identified by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-10-CM) diagnosis codes for OUD during the 6-month cohort preindex period were excluded. The 6-month preindex period (prepandemic cohort: September 2018 to February 2019; pandemic cohort: September 2019 to February 2020) was followed by a 6-month index period (prepandemic cohort: March 2019 to August 2019; pandemic cohort: March 2020 to August 2020) when beneficiaries were enrolled in each cohort, then a 6-month cohort follow-up period (prepandemic cohort: September 2019 to February 2020; pandemic cohort: September 2020 to February 2021)10 (eFigure in Supplement 1). This cohort study was covered by the Common Rule exemption, 45 CFR 46.104(d)(4)(iv), and did not require institutional review board review (ie, the data were deidentified). This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline.
Outcomes
The main outcomes were (1) receipt of OUD-related telehealth services; (2) receipt of MOUD (MOUD from OTPs, buprenorphine in office-based settings, extended-release (ER) naltrexone in office-based settings); and (3) fatal drug overdose. Receipt of OUD-related telehealth services was defined as a Medicare Part A or B service claim with OUD diagnosis and telehealth service code, defined by either Place of Service code 02 and/or a combination of Healthcare Common Procedure Coding System (HCPCS) modifier codes and HCPCS or Current Procedural Terminology codes on the claim. Receipt of MOUD from OTPs was defined as having a Part B claim with HCPCS codes corresponding to receipt of MOUD. Receipt of buprenorphine or ER naltrexone in office-based settings was defined as having a Part D pharmacy claim with a National Drug Code for buprenorphine products approved for OUD treatment or for ER naltrexone. Drug overdose deaths were identified with International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes underlying cause of death (X40-44, X60-64, X85, and Y10-14) and occurring after the beneficiary entered the cohort (eTable in Supplement 1).
Statistical Analysis
Baseline demographic and clinical characteristics were examined by cohort and reported as frequencies and percentages. The number and rate of deaths per 1000 beneficiaries from all causes and the number of deaths due to drug overdose and the percentage of all deaths due to drug overdose were examined by cohort. To assess differences between cohorts, we used the χ2 test for proportions and percentages.
For the pandemic cohort, a multilevel logistic regression model examined associations between fatal drug overdose during the study period and receipt of OUD-related telehealth services and MOUD. The model was adjusted for baseline characteristics, percentage of days during study period patients received any OUD-related services, and percentage of days patients received any non-OUD–related services; beneficiary state of residence was included as a level 2 random intercepts parameter to adjust for similarity of beneficiaries residing in the same state. Results are presented as adjusted odds ratios (aORs) and corresponding 95% CIs. Multicollinearity was not identified in final models. Statistical significance was set at P < .05, and all P values were 2-tailed. Analyses were conducted with SAS Enterprise Guide, version 7.1 (SAS Institute Inc) and Stata, version 17.0 (StataCorp).
Results
The sociodemographic and clinical characteristics of the prepandemic (n = 105 162) and pandemic (n = 70 479) cohort beneficiaries are presented in Table 1. A larger percentage of the beneficiaries in the pandemic cohort received OUD-related telehealth services than beneficiaries in the prepandemic cohort (13 809 beneficiaries [19.6%] vs 590 beneficiaries [0.6%]; P < .001). Receipt of MOUD was higher in the pandemic cohort than in the prepandemic cohort (8826 beneficiaries [12.6%] vs 11 304 beneficiaries [10.8%]; P < .001).

Discussion
Medicare beneficiaries starting a new episode of OUD-related care during the pandemic who received OUD-related telehealth services had a 33% lower adjusted odds of a fatal drug overdose, even after accounting for OUD and non-OUD care engagement and receipt of MOUD. This is consistent with our previous study that found OUD-related telehealth services were associated with reduced risk for nonfatal overdose.7 We also found that receipt of MOUD from OTPs and receipt of buprenorphine in office-based settings were associated with 59% and 38% lower adjusted odds of fatal drug overdose, respectively. In contrast, consistent with prior research,11,12 receipt of ER naltrexone was not associated with a lower risk for overdose death, nor with a lower risk for nonfatal overdose in our prior study.7
All-cause mortality and drug overdose deaths were higher in the pandemic cohort compared with the prepandemic cohort. This increase in overdose deaths among the pandemic cohort is consistent with national trends showing a 31% increase in overdose deaths between 2019 and 2020.13
Despite encouraging findings associated with telehealth and MOUD, only 1 in 5 Medicare beneficiaries in our pandemic cohort received OUD-related telehealth services, and only 1 in 8 received MOUD, underscoring the need for continued expansion of these potentially life-saving interventions across clinical settings.14,15 In addition, our study highlights several findings for future research. For example, exploring why tobacco use disorders were associated with an increased risk, cannabis use disorders with a decreased risk, and alcohol use disorders not associated with a risk for fatal overdose is warranted. Similarly, cancer, obesity, and pain diagnoses were all associated with a lower risk for fatal overdose.
Limitations
Our study contains Medicare FFS beneficiaries that sought and received care before and during the pandemic; the findings might not generalize to Medicare populations not seeking services or to other populations. Our study required individuals to have an ICD-10-CM OUD diagnosis code; it is possible that some individuals with OUD were not recorded with an OUD diagnosis and thus not included in this study. The provision of telehealth may be underestimated because differential uptake by clinicians and health systems of telehealth billing codes added during the initial phases of the pandemic may have occurred. Given the observational nature of the study, we cannot draw causal inferences.
Conclusions
This cohort study found that receipt of OUD-related telehealth services was associated with a reduced risk for fatal drug overdose, as was receipt of MOUD from OTPs and receipt of buprenorphine in office-based settings, demonstrating the potential benefits of continuing these services.
