Physicians’ self-reported knowledge and behaviors related to prescribing opioids for chronic pain and diagnosing opioid use disorder, DocStyles, 2020
Ragan-Burnett KR , Curtis CR , Schmit KM , Mikosz CA , Schieber LZ , Guy GP , Haegerich TM . AJPM Focus 2024 3 (6) Introduction: In 2016, the Centers for Disease Control and Prevention released the Guideline for Prescribing Opioids for Chronic Pain (2016 Centers for Disease Control and Prevention Guideline) to improve opioid prescribing while minimizing associated risks. This analysis sought to understand guideline-concordant knowledge and self-reported practices among primary care physicians. Methods: Data from Spring DocStyles 2020, a cross-sectional, web-based survey of practicing U.S. physicians, were analyzed in 2022 and 2023. Demographic, knowledge, and practice characteristics of primary care physicians overall (N=1,007) and among specific subsets—(1) primary care physicians who provided care for patients with chronic pain (n=600), (2) primary care physicians who did not provide care for patients with chronic pain (n=337), and (3) primary care physicians who reported not obtaining or seeking a buprenorphine waiver (n=624)—were examined. Results: A majority of physicians (72.6%) were unable to select a series of options consistent with diagnostic criteria for opioid use disorder; of those physicians, almost half (47.9%) reported treating at least 1 patient with medications for opioid use disorder. A minority of physicians (17.5%) reported having a buprenorphine prescribing waiver. Among physicians who prescribed opioids for chronic pain (88.5%), 54.4% concurrently prescribed benzodiazepines. About one third (33.5%) reported not taking patients with chronic pain. Conclusions: There were critical practice gaps among primary care physicians related to 2016 Centers for Disease Control and Prevention Guideline topics. Increasing knowledge of the Centers for Disease Control and Prevention's opioid prescribing recommendations can benefit physician practice, patient outcomes, and public health strategies in addressing the opioid overdose crisis and implementing safer and more effective pain care. © 2024 |
Association between length of buprenorphine or methadone use and nonprescribed opioid use among individuals with opioid use disorder: A cohort study
Jiang X , Guy GP Jr , Dever JA , Richardson JS , Dunlap LJ , Turcios D , Wolicki SB , Edlund MJ , Losby JL . Subst Use Addctn J 2024 29767342241266038 BACKGROUND: Opioid use disorder (OUD) affects millions of individuals each year in the United States. Patient retention in medications for opioid use disorder (MOUD) treatment is suboptimal. This study examines and quantifies the associations between each additional month of buprenorphine or methadone use and nonprescribed opioid use. METHODS: Data were obtained from an 18-month longitudinal, observational cohort study of patients (age ≥ 18 years) treated for OUD. Patients completed a baseline self-reported questionnaire between March 2018 and December 2019 and were asked to complete follow-up questionnaires at approximately 3-, 6-, 12-, and 18-months post-baseline until May 2021. Patients treated with buprenorphine or methadone, without taking other MOUD at least 12 months prior to baseline, were included. Outcomes included past 30-day use of prescription opioids nonmedically, heroin, or illegally made fentanyl. A multivariable, multilevel regression model with a binomial distribution and a logit link was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: This study included 353 patients taking buprenorphine (mean [standard deviation, SD] age 39 [11] years; 226 [64%] female), and 785 patients taking methadone (mean [SD] age 42 [12] years; 392 [50%] female). Each additional month of MOUD treatment was associated with a 25% decrease in the odds of past 30-day nonprescribed opioid use for patients taking buprenorphine (aOR [95% CI] = 0.75 [0.68-0.83]), and a 17% decrease for patients taking methadone (aOR = 0.83 [0.79-0.87]). The COVID-19 pandemic (aOR = 9.29 [2.96-29.17]; aOR = 3.19 [1.74-5.86]) and MOUD adverse reaction experiences (aOR = 3.07 [1.11-8.48]; aOR = 2.51 [1.01-6.22]) were significantly associated with higher odds of nonprescribed opioid use among buprenorphine and methadone groups. CONCLUSION: Among patients treated with buprenorphine or methadone, with each additional treatment month since baseline, those who continued with treatment appeared to be more likely to report 17% to 25% decreased odds of past 30-day nonprescribed opioid use. Our findings can be used by clinicians in the shared decision-making process with patients, emphasizing the value of sustained retention in MOUD. |

Substance use patterns and characteristics using real world data from adolescents assessed for substance use and treatment planning-United States, 2017-2021
Jiang X , Guy GP Jr , Schmit K , Hoots B , Roehler DR , Govoni TD , Mallory V , Green JL . Subst Use Misuse 2024 1-18 BACKGROUND: Although substance use rates among adolescents have decreased, drug overdose deaths among adolescents have increased since 2020, driven largely by illegally made fentanyl (IMF). This study explores substance use patterns and characteristics of adolescents who were assessed for substance use disorder (SUD) treatment to inform prevention and response strategies. METHODS: A convenience sample of adolescents aged 10-18 years assessed for SUD treatment from September 2017 to December 2021 was analyzed using the Comprehensive Health Assessment for Teens. The percentage of lifetime and past 30-day substance use was examined. Adolescent characteristics (e.g., demographics, history of overdoses or hospital visits due to drug/alcohol use) were analyzed by lifetime substances used. RESULTS: Among 5,377 assessments, most were male (58.7%), aged 16-18 years (50.5%), non-Hispanic White (43.1%), enrolled in school (87.3%), and living with their parent(s) (72.4%). The most commonly reported lifetime substances used were marijuana (68.0%), alcohol (54.2%), and prescription opioid misuse (13.6%). The most common past 30-day substance use combination was alcohol and marijuana (35.6%). The percentage of assessments indicating past-year overdoses or hospital visits due to drug/alcohol use was greatest among those who reported lifetime use of IMF (24.0%), followed by heroin (21.4%) and cocaine (15.3%). Overall, 2.3% reported lifetime IMF use and 0.6% thought IMF was causing them the most problems. CONCLUSIONS: Findings inform opportunities to address substance use and increased IMF-involved overdose among adolescents. Continued overdose prevention and response strategies such as evidence-based education campaigns, naloxone distribution and harm reduction efforts, and evidence-based SUD treatment expansion are needed. |
Reported xylazine use among adults aged ≥18 years evaluated for substance use treatment - United States, July 2022-September 2023
Jiang X , Connolly S , Strahan AE , Rivera Blanco L , Mikosz CA , Guy GP Jr , Dowell D . MMWR Morb Mortal Wkly Rep 2024 73 (26) 594-599 Xylazine has been increasingly detected in illegally manufactured fentanyl (IMF) products and overdose deaths in the United States; most xylazine-involved overdose deaths involve IMF. A convenience sample of U.S. adults aged ≥18 years was identified from those evaluated for substance use treatment during July 2022-September 2023. Data were collected using the Addiction Severity Index-Multimedia Version clinical assessment tool. Among 43,947 adults, 6,415 (14.6%) reported IMF or heroin as their primary lifetime substance-use problem; 5,344 (12.2%) reported recent (i.e., past-30-day) IMF or heroin use. Among adults reporting IMF or heroin as their primary lifetime substance-use problem, 817 (12.7%) reported ever using xylazine. Among adults reporting recent IMF or heroin use, 443 (8.3%) reported recent xylazine use. Among adults reporting IMF or heroin use recently or as their primary lifetime substance-use problem, those reporting xylazine use reported a median of two past nonfatal overdoses from any drug compared with a median of one overdose among those who did not report xylazine use; as well, higher percentages of persons who reported xylazine use reported other recent substance use and polysubstance use. Provision of nonjudgmental care and services, including naloxone, wound care, and linkage to and retention of persons in effective substance use treatment, might reduce harms including overdose among persons reporting xylazine use. |

Estimated number of children who lost a parent to drug overdose in the US from 2011 to 2021
Jones CM , Zhang K , Han B , Guy GP , Losby J , Einstein EB , Delphin-Rittmon M , Volkow ND , Compton WM . JAMA Psychiatry 2024 IMPORTANCE: Parents' overdose death can have a profound short- and long-term impact on their children, yet little is known about the number of children who have lost a parent to drug overdose in the US. OBJECTIVE: To estimate the number and rate of children who have lost a parent to drug overdose from 2011 to 2021 overall and by parental age, sex, and race and ethnicity. DESIGN, SETTING, AND PARTICIPANTS: This was a cross-sectional study of US community-dwelling persons using data from the National Survey on Drug Use and Health (2010-2014 and 2015-2019) and the National Vital Statistics System (2011-2021). Data were analyzed from January to June 2023. EXPOSURE: Parental drug overdose death, stratified by age group, sex, and race and ethnicity. MAIN OUTCOMES AND MEASURES: Numbers, rates, and average annual percentage change (AAPC) in rates of children losing a parent aged 18 to 64 years to drug overdose, overall and by age, sex, and race and ethnicity. RESULTS: From 2011 to 2021, 649 599 adults aged 18 to 64 years died from a drug overdose (mean [SD] age, 41.7 [12.0] years; 430 050 [66.2%] male and 219 549 [33.8%] female; 62 606 [9.6%] Hispanic, 6899 [1.1%] non-Hispanic American Indian or Alaska Native, 6133 [0.9%] non-Hispanic Asian or Pacific Islander, 82 313 [12.7%] non-Hispanic Black, 485 623 [74.8%] non-Hispanic White, and 6025 [0.9%] non-Hispanic with more than 1 race). Among these decedents, from 2011 to 2021, an estimated 321 566 (95% CI, 276 592-366 662) community-dwelling children lost a parent aged 18 to 64 years to drug overdose. The rate of community-dwelling children who lost a parent to drug overdose per 100 000 children increased from 27.0 per 100 000 in 2011 to 63.1 per 100 000 in 2021. The highest rates were found among children of non-Hispanic American Indian or Alaska Native individuals, who had a rate of 187.1 per 100 000 in 2021, more than double the rate among children of non-Hispanic White individuals (76.5 per 100 000) and non-Hispanic Black individuals (73.2 per 100 000). While rates increased consistently each year for all parental age, sex, and race and ethnicity groups, non-Hispanic Black parents aged 18 to 25 years had the largest AAPC (23.8%; 95% CI, 16.5-31.6). Rates increased for both fathers and mothers; however, more children overall lost fathers (estimated 192 459; 95% CI, 164 081-220 838) than mothers (estimated 129 107; 95% CI, 112 510-145 824). CONCLUSIONS AND RELEVANCE: An estimated 321 566 children lost a parent to drug overdose in the US from 2011 to 2021, with significant disparities evident across racial and ethnic groups. Given the potential short- and long-term negative impact of parental loss, program and policy planning should ensure that responses to the overdose crisis account for the full burden of drug overdose on families and children, including addressing the economic, social, educational, and health care needs of children who have lost parents to overdose. |
Public health interventions and overdose-related outcomes among persons with opioid use disorder
Nataraj N , Rikard SM , Zhang K , Jiang X , Guy GP Jr , Rice K , Mattson CL , Gladden RM , Mustaquim DM , Illg ZN , Seth P , Noonan RK , Losby JL . JAMA Netw Open 2024 7 (4) e244617 IMPORTANCE: Given the high number of opioid overdose deaths in the US and the complex epidemiology of opioid use disorder (OUD), systems models can serve as a tool to identify opportunities for public health interventions. OBJECTIVE: To estimate the projected 3-year association between public health interventions and opioid overdose-related outcomes among persons with OUD. DESIGN, SETTING, AND PARTICIPANTS: This decision analytical model used a simulation model of the estimated US population aged 12 years and older with OUD that was developed and analyzed between January 2019 and December 2023. The model was parameterized and calibrated using 2019 to 2020 data and used to estimate the relative change in outcomes associated with simulated public health interventions implemented between 2021 and 2023. MAIN OUTCOMES AND MEASURES: Projected OUD and medications for OUD (MOUD) prevalence in 2023 and number of nonfatal and fatal opioid-involved overdoses among persons with OUD between 2021 and 2023. RESULTS: In a baseline scenario assuming parameters calibrated using 2019 to 2020 data remained constant, the model projected more than 16 million persons with OUD not receiving MOUD treatment and nearly 1.7 million persons receiving MOUD treatment in 2023. Additionally, the model projected over 5 million nonfatal and over 145 000 fatal opioid-involved overdoses among persons with OUD between 2021 and 2023. When simulating combinations of interventions that involved reducing overdose rates by 50%, the model projected decreases of up to 35.2% in nonfatal and 36.6% in fatal opioid-involved overdoses among persons with OUD. Interventions specific to persons with OUD not currently receiving MOUD treatment demonstrated the greatest reduction in numbers of nonfatal and fatal overdoses. Combinations of interventions that increased MOUD initiation and decreased OUD recurrence were projected to reduce OUD prevalence by up to 23.4%, increase MOUD prevalence by up to 137.1%, and reduce nonfatal and fatal opioid-involved overdoses among persons with OUD by 6.7% and 3.5%, respectively. CONCLUSIONS AND RELEVANCE: In this decision analytical model study of persons with OUD, findings suggested that expansion of evidence-based interventions that directly reduce the risk of overdose fatality among persons with OUD, such as through harm reduction efforts, could engender the highest reductions in fatal overdoses in the short-term. Interventions aimed at increasing MOUD initiation and retention of persons in treatment projected considerable improvement in MOUD and OUD prevalence but could require a longer time horizon for substantial reductions in opioid-involved overdoses. |
Barriers to retention in medications for opioid use disorder treatment in real-world practice
Villamil VI , Underwood N , Cremer LJ , Rooks-Peck CR , Jiang X , Guy GP . J Subst Use Addict Treat 2024 160 209310 BACKGROUND: Medications for Opioid Use Disorder (MOUD) are an effective method to treat persons with opioid use disorder (OUD). Longer treatment times are associated with better health outcomes, yet treatment retention rates remain low. This study aimed to assess patient characteristics and experiences associated with retention in treatment. METHODS: Data were from an observational cohort study of OUD treatments. Among persons receiving buprenorphine or methadone, log-binomial regression models assessed the relationship between patient characteristics and experiences and three retention outcomes: retention in any OUD treatment, retention in the index treatment (OUD treatment being administered at the time when patients were screened for study eligibility), and 6-month retention in the index treatment. RESULTS: Individuals being treated with methadone at the start of the study compared to those treated with buprenorphine were more likely to remain in their same index treatment at the 18-month follow-up (aPR = 1.35; 95 % CI = 1.11-1.65), and to have remained on their index treatment for 6-months or longer (aPR = 1.22; 95 % CI = 1.14-1.32), but were not significantly more likely to remain in any OUD treatment overall. Individuals residing five miles or less from treatment were more likely to have been retained in any OUD treatment (aPR = 1.06; 95 % CI = 1.00-1.12), to remain in their index treatment at the 18-month follow-up (aPR = 1.21; 95 % CI = 1.08-1.36), and to have remained in their index treatment for 6 months or more (aPR = 1.08; 95 % CI = 1.02-1.13). Individuals without health insurance were less likely to be retained in any OUD treatment (aPR = 0.86; 95 % CI = 0.78-0.95). CONCLUSION: The prevalence of retention in any OUD treatment was higher for individuals residing five miles or less from treatment. These findings expand on previous studies that have shown distance to and location of treatment sites can impact treatment access and retention. Lack of health insurance was also associated with lower retention in any OUD treatment in this study. Given the high burden associated with overdose deaths, it is important to understand and address barriers to retention in treatment. |
Characteristics of alcohol, marijuana, and other drug use among persons aged 13-18 years being assessed for substance use disorder treatment - United States, 2014-2022
Connolly S , Govoni TD , Jiang X , Terranella A , Guy GP Jr , Green JL , Mikosz C . MMWR Morb Mortal Wkly Rep 2024 73 (5) 93-98 Substance use often begins during adolescence, placing youths at risk for fatal overdose and substance use disorders (SUD) in adulthood. Understanding the motivations reported by adolescents for using alcohol, marijuana, and other drugs and the persons with whom they use these substances could guide strategies to prevent or reduce substance use and its related consequences among adolescents. A cross-sectional study was conducted among adolescents being assessed for SUD treatment in the United States during 2014-2022, to examine self-reported motivations for using substances and the persons with whom substances were used. The most commonly reported motivation for substance use was "to feel mellow, calm, or relaxed" (73%), with other stress-related motivations among the top reasons, including "to stop worrying about a problem or to forget bad memories" (44%) and "to help with depression or anxiety" (40%); one half (50%) reported using substances "to have fun or experiment." The majority of adolescents reported using substances with friends (81%) or using alone (50%). These findings suggest that interventions related to reducing stress and addressing mental health concerns might reduce these leading motivations for substance use among adolescents. Education for adolescents about harm reduction strategies, including the danger of using drugs while alone and how to recognize and respond to an overdose, can reduce the risk for fatal overdose. |

The medications for opioid use disorder study: Methods and initial outcomes from an 18-month study of patients in treatment for opioid use disorder
Dever JA , Hertz MF , Dunlap LJ , Richardson JS , Wolicki SB , Biggers BB , Edlund MJ , Bohm MK , Turcios D , Jiang X , Zhou H , Evans ME , Guy GP Jr . Public Health Rep 2024 333549231222479 OBJECTIVE: Opioid use disorder (OUD) affects approximately 5.6 million people in the United States annually, yet rates of the use of effective medication for OUD (MOUD) treatment are low. We conducted an observational cohort study from August 2017 through May 2021, the MOUD Study, to better understand treatment engagement and factors that may influence treatment experiences and outcomes. In this article, we describe the study design, data collected, and treatment outcomes. METHODS: We recruited adult patients receiving OUD treatment at US outpatient facilities for the MOUD Study. We collected patient-level data at 5 time points (baseline to 18 months) via self-administered questionnaires and health record data. We collected facility-level data via questionnaires administered to facility directors at 2 time points. Across 16 states, 62 OUD treatment facilities participated, and 1974 patients enrolled in the study. We summarized descriptive data on the characteristics of patients and OUD treatment facilities and selected treatment outcomes. RESULTS: Approximately half of the 62 facilities were private, nonprofit organizations; 62% focused primarily on substance use treatment; and 20% also offered mental health services. Most participants were receiving methadone (61%) or buprenorphine (32%) and were predominately non-Hispanic White (68%), aged 25-44 years (62%), and female (54%). Compared with patient-reported estimates at baseline, 18-month estimates suggested that rates of abstinence increased (55% to 77%), and rates of opioid-related overdoses (7% to 2%), emergency department visits (9% to 4%), and arrests (15% to 7%) decreased. CONCLUSIONS: Our results demonstrated the benefits of treatment retention not only on abstinence from opioid use but also on other quality-of-life metrics, with data collected during an extended period. The MOUD Study produced rich, multilevel data that can lay the foundation for an evidence base to inform OUD treatment and support improvement of care and patient outcomes. |
Prevalence of pharmacologic and nonpharmacologic pain management therapies among adults with chronic pain-United States, 2020
Rikard SM , Strahan AE , Schmit KM , Guy GP Jr . Ann Intern Med 2023 176 (11) 1571-1575 Background: In 2021, approximately 1 in 5 adults in the United States experienced chronic pain (1). The Centers for Disease Control and Prevention’s “CDC Clinical Practice Guideline for Prescribing Opioids for Pain — United States, 2022” (2) recommends maximizing nonpharmacologic and nonopioid therapies for pain as appropriate for the specific condition and patient. Whereas previous research reported the prevalence of use of nonpharmacologic and opioid therapies for pain (3), this study adds information about prescription nonopioids, over-the-counter pain relievers, and exercise. | | Objective: To estimate the prevalence of use of pharmacologic and nonpharmacologic therapies among adults with chronic pain in the United States. | | Methods and Findings: We used the 2020 National Health Interview Survey (NHIS) (31 568 total respondents) to identify adults who self-reported pain on most days or every day in the past 3 months (unweighted n = 7422) (4). Respondents reported use of pharmacologic (prescription opioids, prescription nonopioids, over-the-counter pain relievers) and nonpharmacologic (physical or occupational therapy [PT/OT], cognitive behavioral therapy [CBT], exercise, complementary therapies) pain management therapies in the past 3 months. We report therapy prevalence overall and by demographic characteristics. Adjusted prevalence was estimated using predictive margins from multivariable logistic regression models. All analyses account for the complex NHIS survey design. This study was exempt from institutional review board review. | | In 2020, approximately 54 million adults self-reported chronic pain. Among pharmacologic therapies, use of over-the-counter pain relievers in the past 3 months was most prevalent (75.5%), followed by prescription nonopioids (31.3%) and prescription opioids (13.5%) (Table 1). Among nonpharmacologic therapies, exercise was most prevalent (55.0%), followed by complementary therapies (36.7%), PT/OT (17.2%), and CBT (2.6%). Pharmacologic therapy use alone was reported by 26.6% of adults, with most (22.4%) reporting nonopioid use only and 1.0% reporting opioid use only. Most adults (60.2%) reported using both pharmacologic and nonpharmacologic therapies, with 50.9% reporting nonopioid and nonpharmacologic therapy use and 7.7% reporting combined use of opioids, nonopioids, and nonpharmacologic therapy. |
Weathering the storm: Syringe services program laws and human immunodeficiency virus during the COVID-19 pandemic
Jackson H , Dunphy C , Grist MB , Jiang X , Xu L , Guy GP Jr , Salvant-Valentine S . J Acquir Immune Defic Syndr 2023 94 (5) 395-402 BACKGROUND: Syringe services programs (SSPs) are community-based prevention programs that provide a range of harm reduction services to persons who inject drugs. Despite their benefits, SSP laws vary across the United States. Little is known regarding how legislation surrounding SSPs may have influenced HIV transmission over the COVID-19 pandemic, a period in which drug use increased. This study examined associations between state SSP laws and HIV transmission among the Medicaid population before and after the COVID-19 pandemic. METHODS: State-by-month counts of new HIV diagnoses among the Medicaid population were produced using administrative claims data from the Transformed Medicaid Statistical Information System from 2019 to 2020. Data on SSP laws were collected from the Prescription Drug Abuse Policy System. Associations between state SSP laws and HIV transmission before and after the start of the COVID-19 pandemic were evaluated using an event study design, controlling for the implementation of COVID-19 nonpharmaceutical interventions and state and time fixed effects. RESULTS: State laws allowing the operation of SSPs were associated with 0.54 (P = 0.044) to 1.18 (P = 0.001) fewer new monthly HIV diagnoses per 100,000 Medicaid enrollees relative to states without such laws in place during the 9 months after the start of the COVID-19 pandemic. The largest effects manifested for population subgroups disproportionately affected by HIV, such as male and non-Hispanic Black Medicaid enrollees. CONCLUSION: Less restrictive laws on SSPs may have helped mitigate HIV transmission among the Medicaid population throughout the COVID-19 pandemic. Policymakers can consider implementing less restrictive SSP laws to mitigate HIV transmission resulting from future increases in injection drug use.

Sources of nonmedically used prescription psychotherapeutic drugs using real-world data from adolescents and adults assessed for substance use treatment--2014-2022
Jiang X , Govoni TD , Illg Z , Connolly S , Green JL , Guy GP Jr . Res Social Adm Pharm 2023 BACKGROUND: Nonmedical use (NMU) of prescription psychotherapeutic drugs (PPD) may increase risk for significant morbidity and mortality in the overdose crisis. OBJECTIVE: This study examines sources of PPD using real-world data from adolescents and adults reporting past 30-day NMU of PPDs. METHODS: A convenience sample of individuals aged ≥10 years assessed for substance use disorders (SUD) treatment was analyzed using the 2014-2022 National Addictions Vigilance Intervention and Prevention Program datasets. PPD include prescription opioids, prescription tranquilizers/sedatives, and prescription stimulants. RESULTS: Overall, among assessments of adolescents aged 10-18 years (N = 1991) and young adults aged 19-24 years (N = 15,166), "family/friend" (46.08-47.41 %) and "dealer" (33.82-42.71 %) were the most common sources. Among assessments of adults aged ≥25 years (N = 89,225), "own prescription" was the most common source and increased in frequency as age increased. Across all age groups, "family/friend" was the most frequent source for all drug classes (41.96-48.76 %) except for nonmedically used buprenorphine/methadone, for which "own prescription" was the most common source (51.85 %) among adults. CONCLUSIONS: Our study demonstrates heterogeneity in sources of nonmedically used PPD across age groups. Tailored prevention strategies for different age groups and improving timely access to medical care to ensure proper treatment of chronic medical conditions including SUD are needed. |
One-year association of drug possession law change with fatal drug overdose in Oregon and Washington
Joshi S , Rivera BD , Cerdá M , Guy GP Jr , Strahan A , Wheelock H , Davis CS . JAMA Psychiatry 2023 IMPORTANCE: Two states modified laws to remove or substantially reduce criminal penalties for any drug possession. The hypothesis was that removing criminal penalties for drug possession may reduce fatal drug overdoses due to reduced incarceration and increased calls for help at the scene of an overdose. OBJECTIVE: To evaluate whether decriminalization of drug possession in Oregon and Washington was associated with changes in either direction in fatal drug overdose rates. DESIGN, SETTING, AND PARTICIPANTS: This cohort study used a synthetic control method approach to examine whether there were changes in drug possession laws and fatal drug overdose rates in Oregon and Washington in the postpolicy period (February 1, 2021, to March 31, 2022, in Oregon and March 1, 2021, to March 31, 2022, in Washington). A counterfactual comparison group (synthetic controls) was created for Oregon and Washington, using 48 states and the District of Columbia, that did not implement similar policies during the study period (January 1, 2018, to March 31, 2022). For 2018-2021, final multiple cause-of-death data from the National Vital Statistics System (NVSS) were used. For 2022, provisional NVSS data were used. Drug overdose deaths were identified using International Statistical Classification of Diseases and Related Health Problems, 10th Revision underlying cause-of-death codes X40-X44, X60-X64, X85, and Y10-Y14. EXPOSURES: In Oregon, Measure 110 went into effect on February 1, 2021. In Washington, the Washington Supreme Court decision in State v Blake occurred on February 25, 2021. MAIN OUTCOME: Monthly fatal drug overdose rates. RESULTS: Following the implementation of Measure 110, absolute monthly rate differences between Oregon and its synthetic control were not statistically significant (probability = 0.26). The average rate difference post Measure 110 was 0.268 fatal drug overdoses per 100 000 state population. Following the implementation of the policy change in Washington, the absolute monthly rate differences between Washington and synthetic Washington were not statistically significant (probability = 0.06). The average rate difference post Blake was 0.112 fatal drug overdoses per 100 000 state population. CONCLUSIONS AND RELEVANCE: This study found no evidence of an association between legal changes that removed or substantially reduced criminal penalties for drug possession in Oregon and Washington and fatal drug overdose rates. Additional research could examine potential other outcomes as well as longer-term associations with fatal drug overdose overall and across racial and ethnic groups. |
State-to-state variation in opioid dispensing changes following the release of the 2016 CDC Guideline for Prescribing Opioids for Chronic Pain
Lyu X , Guy GP , Baldwin GT , Losby JL , Bohnert ASB , Goldstick JE . JAMA Netw Open 2023 6 (9) e2332507 IMPORTANCE: Evidence suggests that opioid prescribing was reduced nationally following the 2016 release of the Guideline for Prescribing Opioids for Chronic Pain by the US Centers for Diseases Control and Prevention (CDC). State-to-state variability in postguideline changes has not been quantified and could point to further avenues for reducing opioid-related harms. OBJECTIVE: To estimate state-level changes in opioid dispensing following the 2016 CDC Guideline release and explore state-to-state heterogeneity in those changes. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study included information on opioid prescriptions for US individuals between 2012 and 2018 from an administrative database. Serial cross-sections of monthly opioid dispensing trajectories in each US state and the District of Columbia were analyzed using segmented regression to characterize preguideline dispensing trajectories and to estimate how those trajectories changed following the 2016 guideline release. Data were analyzed January to March 2023. EXPOSURE: The March 2016 CDC Guideline for Prescribing Opioids for Chronic Pain. MAIN OUTCOMES AND MEASURES: Four measures of opioid dispensing: opioid dispensing rate per 100 000 persons, long-acting opioid dispensing rate per 100 000 persons, high-dose (90 or more morphine milligram equivalents [MME] per day) dispensing rate per 100 000 persons, and average per capita MME. All measures were calculated monthly, from January 2012 through December 2018. RESULTS: Data from approximately 58 900 retail pharmacies were included in analysis, representing approximately 92% of US retail prescriptions. The overall monthly dispensing rate in the US in early 2012 was approximately 7000 per 100 000 population. Following the 2016 guideline release, the already-decreasing slope accelerated nationally for the overall dispensing rate (preguideline slope, -23.19; postguideline slope, -48.97; change in slope, 25.97 [95% CI, 18.67-32.95]), long-acting dispensing rate (preguideline slope, -1.03; postguideline slope, -5.94; change in slope, 4.90 [95% CI, 4.26-5.55]), high-dose dispensing (preguideline slope, -3.52; postguideline slope, -7.63; change in slope, 4.11 [95% CI, 3.49-4.73]), and per-capita MME (preguideline slope, -0.22; postguideline slope, -0.58; change in slope, 0.36 [95% CI, 0.30-0.42]). For all outcomes, nearly all states showed analogous acceleration of an already-decreasing slope, but there was substantial state-to-state heterogeneity. Slope changes (preguideline - postguideline slope) ranged from 9.15 (Massachusetts) to 74.75 (Mississippi) for overall dispensing, 1.88 (Rhode Island) to 13.41 (Maine) for long-acting dispensing, 0.71 (District of Columbia) to 13.68 (Maine) for high-dose dispensing, and 0.06 (Hawaii) to 0.91 (Arkansas) for per capita MME. CONCLUSIONS AND RELEVANCE: The 2016 CDC Guideline release was associated with broad reductions in prescription opioid dispensing, and those changes showed substantial geographic variability. Determining the factors associated with these state-level differences may inform further improvements to ensure safe prescribing practices. |
Longitudinal dose patterns among patients newly initiated on long-term opioid therapy in the United States, 2018 to 2019: an observational cohort study and time-series cluster analysis
Rikard SM , Nataraj N , Nataraj N , Strahan AE , Mikosz CA , Guy GP Jr . Pain 2023 164 (12) 2675-2683 Opioid prescribing varies widely, and prescribed opioid dosages for an individual can fluctuate over time. Patterns in daily opioid dosage among patients prescribed long-term opioid therapy have not been previously examined. This study uses a novel application of time-series cluster analysis to characterize and visualize daily opioid dosage trajectories and associated demographic characteristics of patients newly initiated on long-term opioid therapy. We used 2018 to 2019 data from the IQVIA Longitudinal Prescription (LRx) all-payer pharmacy database, which covers 92% of retail pharmacy prescriptions dispensed in the United States. We identified a cohort of 277,967 patients newly initiated on long-term opioid therapy during 2018. Patients were stratified into 4 categories based on their mean daily dosage during a 90-day baseline period (<50, 50-89, 90-149, and ≥150 morphine milligram equivalent [MME]) and followed for a 270-day follow-up period. Time-series cluster analysis identified 2 clusters for each of the 3 baseline dosage categories <150 MME and 3 clusters for the baseline dosage category ≥150 MME. One cluster in each baseline dosage category comprised opioid dosage trajectories with decreases in dosage at the end of the follow-up period (80.7%, 98.7%, 98.7%, and 99.0%, respectively), discontinuation (58.5%, 80.0%, 79.3%, and 81.7%, respectively), and rapid tapering (50.8%, 85.8%, 87.5%, and 92.9%, respectively). These findings indicate multiple clusters of patients newly initiated on long-term opioid therapy who experience discontinuation and rapid tapering and highlight potential areas for clinician training to advance evidence-based guideline-concordant opioid prescribing, including strategies to minimize sudden dosage changes, discontinuation, or rapid tapering, and the importance of shared decision-making. |
Increase in Incidence of Neonatal Abstinence Syndrome Among In-Hospital Birth in the United States-Reply
Strahan AE , Guy GP , Ko JY . JAMA Pediatr 2021 175 (1) 100 In Reply We appreciate Ramphul et al sharing estimates of the 2012 rate of in-hospital births with a neonatal abstinence syndrome (NAS) diagnosis. In our study1 of 2016 national incidence and cost estimates for in-hospital births with a NAS diagnosis, we did not make direct comparisons with earlier estimates2 owing to the 2015 transition from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) to International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) and because earlier studies may not have limited the sample to in-hospital births. |
Associations between prescription stimulant use as prescribed, nonmedical use, and illicit stimulant use among adults evaluated for substance use treatment, 2017-2021
Pickens CM , Jones CM , Guy GP Jr , Dailey Govoni T , Green JL . Drug Alcohol Depend Rep 2023 7 100153 BACKGROUND: Limited data exist on risk factors for illicit stimulant use, including associations between prescription stimulant use/nonmedical use (NMU) and illicit stimulant use. METHODS: We used 2017-2021 data from adults assessed for substance use disorder (SUD) treatment using the National Addictions Vigilance Intervention and Prevention Program Addiction Severity Index-Multimedia Version® tool. Multivariable Poisson regression models analyzed associations between past 30-day prescription stimulant use as prescribed or NMU and past 30-day illicit stimulant use. Separate models examined past 30-day illicit stimulant, methamphetamine, and cocaine use. We explored problem severity across seven biopsychosocial domains (e.g., drug, psychiatric, family) by past 30-day prescription stimulant use/NMU and illicit stimulant use. RESULTS: Among 218,981 assessments, 1.8% reported prescription stimulant NMU; 1.6% reported use as prescribed. Past 30-day prescription stimulant NMU (vs. no use) was associated with past 30-day illicit stimulant use (adjusted prevalence ratio [aPR] [95% CI]: 2.67 [2.59, 2.75]), methamphetamine use (aPR: 2.81 [2.71, 2.92]), and cocaine use (aPR: 3.53 [3.33, 3.74]). Prescription stimulant use as prescribed (vs. no use) was associated with lower prevalence of past 30-day illicit stimulant use. Assessments reporting prescription stimulant NMU (vs. no use, or use as prescribed) appeared more likely to have moderate-to-extreme problem scores across biopsychosocial domains, indicating greater need for treatment or assistance. Assessments reporting prescription stimulant use as prescribed or NMU frequently reported opioids, alcohol, or other substances as their primary substance problem. CONCLUSIONS: Adults using illicit stimulants/nonmedically using prescription stimulants may benefit from care addressing polysubstance use, mental health, social, and recovery support services. |
Chronic pain among adults - United States, 2019-2021
Rikard SM , Strahan AE , Schmit KM , Guy GP Jr . MMWR Morb Mortal Wkly Rep 2023 72 (15) 379-385 Chronic pain (i.e., pain lasting ≥3 months) is a debilitating condition that affects daily work and life activities for many adults in the United States and has been linked with depression (1), Alzheimer disease and related dementias (2), higher suicide risk (3), and substance use and misuse (4). During 2016, an estimated 50 million adults in the United States experienced chronic pain, resulting in substantial health care costs and lost productivity (5,6). Addressing chronic pain and improving the lives of persons living with pain is a public health imperative. Population research objectives in the National Pain Strategy, which was released in 2016 by the Interagency Pain Research Coordinating Committee, call for more precise estimates of the prevalence of chronic pain and high-impact chronic pain (i.e., chronic pain that results in substantial restriction to daily activities) in the general population and within various population groups to guide efforts to reduce the impact of chronic pain (3). Further, a 2022 review of U.S. chronic pain surveillance systems identified the National Health Interview Survey (NHIS) as the best source for pain surveillance data (7). CDC analyzed data from the 2019-2021 NHIS to provide updated estimates of the prevalence of chronic pain and high-impact chronic pain among adults in the United States and within population groups defined by demographic, geographic, socioeconomic, and health status characteristics. During 2021, an estimated 20.9% of U.S. adults (51.6 million persons) experienced chronic pain, and 6.9% (17.1 million persons) experienced high-impact chronic pain. New findings from this analysis include that non-Hispanic American Indian or Alaska Native (AI/AN) adults, adults identifying as bisexual, and adults who are divorced or separated are among the populations experiencing a higher prevalence of chronic pain and high-impact chronic pain. Clinicians, practices, health systems, and payers should vigilantly attend to health inequities and ensure access to appropriate, affordable, diversified, coordinated, and effective pain management care for all persons (8). |
Buprenorphine dispensing among youth aged 19 years in the United States: 2015-2020
Terranella A , Guy GP , Mikosz C . Pediatrics 2023 151 (2) BACKGROUND AND OBJECTIVES: Opioid related overdose among adolescents and young adults in the United States is rising. Medications for opioid use disorder (MOUD), including buprenorphine can reduce the risk of overdose, however they are underutilized. A better understanding of buprenorphine prescribing to youth will help inform interventions to expand access to treatment. METHODS: We used IQVIA data to examine buprenorphine dispensing trends among youth aged ≤19 years from 2015 to 2020. Dispensing was examined by prescriber specialty, age, and sex. Data were weighted to provide national estimates. RESULTS: The rate of buprenorphine dispensed to youth decreased 25% over the study period, from 0.84 to 0.63 prescriptions per 1000 youth per year. The proportion of youth dispensed buprenorphine also decreased 45%, from 7.6 to 4.2 persons per 100 000 per year. Over the same time, the proportion of adults aged ≥20 years dispensed buprenorphine increased 47%, from 378 to 593 persons per 100 000. Differences in dispensing by sex and temporal trends were also noted. Pediatricians accounted for less-than 2% of all prescriptions dispensed. CONCLUSIONS: Buprenorphine dispensing to youth is low and declining in recent years. Given rates of opioid use disorder among youth, these findings suggest that many youth who could benefit from MOUD are not receiving it. Pediatricians could play a role in expanding access to MOUD for this high-risk population. Efforts to expand access to MOUD for adolescents could include improving training in opioid use disorder treatment of pediatricians and encouraging all clinicians who care for adolescents and young adults to obtain waivers to prescribe buprenorphine for MOUD. |
Hospitalization associated with comorbid psychiatric and substance use disorders among adults with COVID-19 treated in US emergency departments from April 2020 to August 2021
Schieber LZ , Dunphy C , Schieber RA , Lopes-Cardozo B , Moonesinghe R , Guy GP Jr . JAMA Psychiatry 2023 80 (4) 331-341 IMPORTANCE: During the COVID-19 pandemic, US emergency department (ED) visits for psychiatric disorders (PDs) and drug overdoses increased. Psychiatric disorders and substance use disorders (SUDs) independently increased the risk of COVID-19 hospitalization, yet their effect together is unknown. OBJECTIVE: To assess how comorbid PD and SUD are associated with the probability of hospitalization among ED patients with COVID-19. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cross-sectional study analyzed discharge data for adults (age ≥18 years) with a COVID-19 diagnosis treated in 970 EDs and inpatient hospitals in the United States from April 2020 to August 2021. EXPOSURES: Any past diagnosis of (1) SUD from opioids, stimulants, alcohol, cannabis, cocaine, sedatives, or other substances and/or (2) PD, including attention-deficit/hyperactivity disorder (ADHD), anxiety, bipolar disorder, major depression, other mood disorder, posttraumatic stress disorder (PTSD), or schizophrenia. MAIN OUTCOMES AND MEASURES: The main outcome was any hospitalization. Differences in probability of hospitalization were calculated to assess its association with both PD and SUD compared with PD alone, SUD alone, or neither condition. RESULTS: O 274 219 ED patients with COVID-19 (mean [SD] age, 54.6 [19.1] years; 667 638 women [52.4%]), 18.6% had a PD (mean age, 59.0 years; 37.7% men), 4.6% had a SUD (mean age, 50.1 years; 61.7% men), and 2.3% had both (mean age, 50.4 years; 53.1% men). The most common PDs were anxiety (12.9%), major depression (9.8%), poly (≥2) PDs (6.4%), and schizophrenia (1.4%). The most common SUDs involved alcohol (2.1%), cannabis (1.3%), opioids (1.0%), and poly (≥2) SUDs (0.9%). Prevalence of SUD among patients with PTSD, schizophrenia, other mood disorder, or ADHD each exceeded 21%. Based on significant specific PD-SUD pairs (Q < .05), probability of hospitalization of those with both PD and SUD was higher than those with (1) neither condition by a weighted mean of 20 percentage points (range, 6 to 36; IQR, 16 to 25); (2) PD alone by 12 percentage points (range, -4 to 31; IQR, 8 to 16); and (3) SUD alone by 4 percentage points (range, -7 to 15; IQR, -2 to 7). Associations varied by types of PD and SUD. Substance use disorder was a stronger predictor of hospitalization than PD. CONCLUSIONS AND RELEVANCE: This study found that patients with both PD and SUD had a greater probability of hospitalization, compared with those with either disorder alone or neither disorder. Substance use disorders appear to have a greater association than PDs with the probability of hospitalization. Overlooking possible coexisting PD and SUD in ED patients with COVID-19 can underestimate the likelihood of hospitalization. Screening and assessment of both conditions are needed. |
Trends in out-of-pocket costs for and characteristics of pharmacy-dispensed buprenorphine medications for opioid use disorder treatment by type of payer, 2015 to 2020
Strahan AE , Desai S , Zhang K , Guy GP Jr . JAMA Netw Open 2023 6 (2) e2254590 IMPORTANCE: Buprenorphine has been approved for opioid use disorder treatment, yet remains underutilized. Cost may present a barrier; little is known about how out-of-pocket costs vary. OBJECTIVE: To determine if out-of-pocket costs and prescription characteristics for buprenorphine varied by type of payer. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used all-payer data on retail pharmacy-dispensed buprenorphine prescriptions from January 1, 2015, through December 31, 2020, for adults (aged ≥18 years) in the US, excluding formulations primarily used to treat pain. Data were analyzed from July 2021 to June 2022. EXPOSURES: Type of payer (private and commercial, self-pay, Medicaid, Medicare, assistance, and unknown) for dispensed prescription. MAIN OUTCOMES AND MEASURES: All outcomes are prescription-level. Mean and median daily out-of-pocket costs were calculated overall and by payer type. Prescription characteristics (days supplied, patient age and sex, generic vs name brand formulations, and prescriber's location) were examined by payer type. RESULTS: Although mean daily out-of-pocket costs decreased overall from $4.79 (95% CI, $4.79-$4.80) in 2015 375 508 prescriptions) to $1.91 (95% CI, $1.90-$1.91) in 2020 (13 486 822 prescriptions), out-of-pocket costs continued to vary by payer in 2020. Medicaid had the lowest mean daily out-of-pocket cost across all years-$0.18 (95% CI, $0.18-$0.18) in 2015, and $0.10 (95% CI, $0.10-$0.10) in 2020. Private and commercial paid prescriptions fell from $4.80 (95% CI, $4.79-$4.81) per day in 2015 to $1.82 (95% CI, $1.82-$1.83) in 2020. Self-pay and assistance categories had the highest mean daily out-of-pocket costs across study years ($9.76 [95% CI, $9.74-$9.78] and $8.72 [95% CI, $8.71-$8.73], respectively, in 2015; $8.44 [95% CI, $8.43-$8.46] and $6.31 [95% CI, $6.30-$6.31], respectively, in 2020). Medicaid paid prescriptions had a mean supply of 15.59 days (95% CI, 15.58-15.59 days) and the lowest percentage of generic prescriptions (57.88%; 95% CI, 57.84%-57.92%). Out-of-pocket cost varied by prescriber location and patient characteristics; mean costs were highest for prescriptions written in the South ($2.91; 95% CI, $2.90-$2.91), metropolitan counties ($1.93; 95% CI, $1.93-$1.93), and for individuals aged 35 to 44 years ($2.10; 95% CI, $2.09-$2.10). CONCLUSIONS AND RELEVANCE: This cross-sectional study found that mean daily out-of-pocket costs for buprenorphine were lower in 2020 than in 2015, but variation by payer existed in all study years. Financial barriers to accessing and maintaining buprenorphine for opioid use disorder treatment may exist and differ by type of prescription coverage. Future research could monitor costs and identify potential barriers that may impact access and retention in care. |
Association of Trends in SARS-CoV-2 Seroprevalence and State-Issued Nonpharmaceutical Interventions- United States, August 1, 2020 - March 30, 2021.
Miller MJ , Himschoot A , Fitch N , Jawalkar S , Freeman D , Hilton C , Berney K , Guy GP , Benoit TJ , Clarke KEN , Busch MP , Opsomer JD , Stramer SL , Hall AJ , Gundlapalli AV , MacNeil A , McCord R , Sunshine G , Howard-Williams M , Dunphy C , Jones JM . Clin Infect Dis 2022 75 S264-S270 OBJECTIVES: To assess if state-issued nonpharmaceutical interventions (NPIs) are associated with reduced rates of SARS-CoV-2 infection as measured through anti-nucleocapsid (anti-N) seroprevalence, a proxy for cumulative prior infection that distinguishes seropositivity from vaccination). METHODS: Monthly anti-N seroprevalence during August 1, 2020 - March 30, 2021 was estimated using a nationwide blood donor serosurvey. Using multivariable logistic regression models, we measured the association of seropositivity and state-issued, county-specific NPIs for mask mandates, gathering bans, and bar closures. RESULTS: Compared with individuals living in a county with all three NPIs in place, the odds of having anti-N antibodies were 2.2 (95% CI: 2.0-2.3) times higher for people living in a county that did not have any of the three NPIs, 1.6 (95% CI: 1.5-1.7) times higher for people living in a county that only had a mask mandate and gathering ban policy, and 1.4 (95% CI: 1.3-1.5) times higher for people living in a county that had only a mask mandate. CONCLUSIONS: Consistent with studies assessing NPIs relative to COVID-19 incidence and mortality, the presence of NPIs were associated with lower SARS-CoV-2 seroprevalence indicating lower rates of cumulative infections. Multiple NPIs are likely more effective than single NPIs. |
Patterns in nonopioid pain medication prescribing after the release of the 2016 Guideline for Prescribing Opioids for Chronic Pain
Goldstick JE , Guy GP , Losby JL , Baldwin GT , Myers MG , Bohnert ASB . JAMA Netw Open 2022 5 (6) e2216475 IMPORTANCE: In 2016, the Centers for Disease Control and Prevention (CDC) released the evidence-based Guideline for Prescribing Opioids for Chronic Pain. How the release of this guideline coincided with changes in nonopioid pain medication prescribing rates remains unknown. OBJECTIVE: To evaluate changes in nonopioid pain medication prescribing after the 2016 CDC guideline release and to assess the heterogeneity in these changes as a function of patient demographic and clinical characteristics. DESIGN, SETTING, AND PARTICIPANTS: This cohort study constructed 7 (4 preguideline and 3 postguideline) annual cohorts using claims data from the national Optum Clinformatics Data Mart Database for the period January 1, 2011, through December 31, 2018. The cohorts included adults with commercial insurance, no cancer or palliative care claims, and 2 years of continuous insurance enrollment. Individuals could qualify for inclusion in multiple cohorts. Each cohort covered a 2-year period, with year 1 as the baseline period used to calculate opioid exposure and other clinical characteristics and year 2 as the follow-up period used to calculate prescribing outcomes. Data were analyzed in March 2022. EXPOSURES: The CDC guideline, which was released in March 2016. MAIN OUTCOMES AND MEASURES: The primary outcome was receipt of any nonopioid pain medication prescriptions (analgesics or antipyretics, anticonvulsants, antidepressants, and nonsteroidal anti-inflammatory drugs) during the follow-up period. This postguideline prescribing pattern was compared with estimates based on the preguideline prescribing pattern, and then the differences were stratified by patient clinical characteristics (chronic pain, recent opioid exposure, substance use disorder, anxiety disorder, and mood disorder). RESULTS: A total of 15 879 241 individuals (2015 mean [SD] age, 50.2 [18.6] years; 8 298 271 female patients [52.3%]) qualified for inclusion in 1 or more cohorts. Logistic regression models showed that nonopioid pain medication prescribing odds were higher by 3.0% (95% CI, 2.6%-3.3%) in postguideline year 1, by 8.7% (95% CI, 8.3%-9.2%) in postguideline year 2, and by 9.7% (95% CI, 9.2%-10.3%) in postguideline year 3 than the preguideline pattern-based estimates. The magnitude of the postguideline departures from the preguideline pattern varied by several clinical characteristics (chronic pain, recent opioid exposure, anxiety disorder, and mood disorder). The largest departure was found among those with chronic pain, with postguideline prescribing being higher than estimated in postguideline year 2 (13.6%; 95% CI, 12.7%-14.6%) and postguideline year 3 (14.9%; 95% CI, 13.8%-16.0%). CONCLUSIONS AND RELEVANCE: Results of this study showed increases in nonopioid pain medication prescribing after the release of the 2016 CDC guideline, suggesting that the guideline may be associated with an increase in guideline-concordant care, but additional studies are needed to understand the role of other secular changes in the opioid policy landscape and other sources of nonopioid medication use. |
