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. |
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. |
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. |
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). |
