Health Care Burden Associated with Outpatient Opioid Use Following Inpatient or Outpatient Surgery

BACKGROUND

The treatment of postsurgical pain with prescription opioids has been associated with persistent opioid use and increased health care utilization and costs.

OBJECTIVE

To compare the health care burden between opioid-naive adult patients who were prescribed opioids after a major surgery and opioidnaive adult patients who were not prescribed opioids.

METHODS

Administrative claims data from the IBM Watson Health MarketScan Research Databases for 2010-2016 were used. Opioid-naive adult patients who underwent major inpatient or outpatient surgery and who had at least 1 year of continuous enrollment before and after the index surgery date were eligible for inclusion. Cohorts were defined based on an opioid pharmacy claim between 7 days before index surgery and 1 year after index surgery (opioid use during surgery and inpatient use were not available). To ensure an opioid-naive population, patients with opioid claims between 365 and 8 days before surgery were excluded. Acute medical outcomes, opioid utilization, health care utilization, and costs were measured during the post-index period (index surgery hospitalization and day of index outpatient surgery not included). Predicted costs were estimated from multivariable log-linked gamma-generalized linear models.

RESULTS

The final sample consisted of 1,174,905 opioid-naive patients with an inpatient surgery (73% commercial, 20% Medicare, 7% Medicaid) and 2,930,216 opioid-naive patients with an outpatient surgery (74% commercial, 23% Medicare, and 3% Medicaid). Opioid use after discharge was common among all 3 payer types but was less common among Medicare patients (63% inpatient/43% outpatient) than patients with commercial (80% inpatient/75% outpatient) or Medicaid insurance (86% inpatient/81% outpatient). Across all 3 payers, opioid users were younger, were more likely to be female, and had a higher preoperative comorbidity burden than nonopioid users. In unadjusted analyses, opioid users tended to have more hospitalizations, emergency department visits, and pharmacy claims. Adjusted predicted 1-year post-period total health care costs were significantly higher (P< 0.001) for opioid users than nonopioid users for commercial insurance (inpatient: $22,209 vs. $14,439; outpatient: $13,897 vs. $8,825), Medicare (inpatient: $31,721 vs. $26,761; outpatient: $24,529 vs. $15,225), and Medicaid (inpatient: $13,512 vs. $9,204; outpatient: $11,975 vs. $8,212).

CONCLUSIONS

Filling an outpatient opioid prescription (vs. no opioid prescription) in the 1 year after inpatient or outpatient surgery was associated with increased health care utilization and costs across all payers.

Evaluating non-medical prescription opioid demand using commodity purchase tasks: test-retest reliability and incremental validity

RATIONALE

Non-medical prescription opioid use and opioid use disorder (OUD) present a significant public health concern. Identifying behavioral mechanisms underlying OUD will assist in developing improved prevention and intervention approaches. Behavioral economic demand has been extensively evaluated as a measure of reinforcer valuation for alcohol and cigarettes, whereas prescription opioids have received comparatively little attention.

OBJECTIVES

Utilize a purchase task procedure to measure the incremental validity and test-retest reliability of opioid demand.

METHODS

Individuals reporting past year non-medical prescription opioid use were recruited using the crowdsourcing platform Amazon Mechanical Turk (mTurk). Participants completed an opioid purchase task as well as measures of cannabis demand, delay discounting, and self-reported pain. A 1-month follow-up was used to evaluate test-retest reliability.

RESULTS

More intense and inelastic opioid demand was associated with OUD and more intense cannabis demand was associated with cannabis use disorder. Multivariable models indicated that higher opioid intensity and steeper opioid delay discounting rates each significantly and uniquely predicted OUD. Increased opioid demand intensity, but not elasticity, was associated with higher self-reported pain, and no relationship was observed with perceived pain relief from opioids. Opioid demand showed acceptable-to-good test-retest reliability (e.g., intensity rxx = .75; elasticity rxx = .63). Temporal reliability was lower for cannabis demand (e.g., intensity rxx = .53; elasticity rxx = .58) and discounting rates (rxx = .42-.61).

CONCLUSIONS

Opioid demand was incrementally valid and test-retest reliable as measured by purchase tasks. These findings support behavioral economic demand as a clinically useful measure of drug valuation that is sensitive to individual difference variables.

Opioid misuse, labor market outcomes, and means-tested public expenditures: a conceptual framework

As the opioid epidemic has drawn increased attention, many researchers are attempting to estimate the financial burden of opioid misuse. These estimates have become particularly relevant as state and local governments have begun to take legal action against pharmaceutical manufacturers, distributors, and others who are identified as being potentially responsible for the worsening epidemic. An important category of costs includes those related to the effect of opioid misuse on labor market outcomes and productivity. Most published estimates of opioid-attributable productivity losses estimate the financial burden borne by society, failing to distinguish between costs internalized by individuals and those that spill over to third parties, such as state and federal governments. This article provides an overview and a conceptual framework for 2 types of labor market-related costs borne by state and federal governments that typically have not been incorporated into existing estimates, which may represent important categories of expenditures. Because detailed estimates of lost tax revenue are available elsewhere, this article focuses largely on whether, and how, to incorporate opioid-related expenses incurred by means-tested government programs into more general estimates of the economic harm created by the opioid epidemic.

The opioid epidemic, neonatal abstinence syndrome, and estimated costs for special education services

Children whose mothers used or misused opioids during their pregnancies are at an increased risk of exhibiting cognitive or behavioral impairments in the future, which may result in identifiable disabilities that require special education services in school. The costs associated with these additional educational services, however, have remained unknown. Using data from available empirical work, we calculated a preliminary set of cost estimates of special education and related services for children diagnosed with neonatal abstinence syndrome (NAS). We estimated these costs for a single cohort of children from the Commonwealth of Pennsylvania with a diagnosis of NAS. The resulting cost estimates were $16,506,916 (2017 US$) in total educational services provisions, with $8,253,458 (2017 US$) of these costs attributable to the additional provision of special education services. This estimate includes both opioid use during pregnancy that was linked to NAS in general and NAS that resulted specifically from prescription opioid use. We estimate the total annual education costs for children born in Pennsylvania with NAS associated with maternal use of prescription opioids to be $1,012,506 (2017 US$). Of these costs, we estimate that $506,253 (2017 US$) are attributable to the additional provision of special education services. We detail the calculation of these cost estimates and provide an expanded set of estimates for additional years of special education services (3-year, 5-year, and 13-year, or the K-12 educational time frame). We conclude with a discussion of limitations and suggestions for future work.

Estimated costs to the Pennsylvania criminal justice system resulting from the opioid crisis

The opioid crisis has made financial impacts across all levels of the public sector. This report focuses on costs related to the criminal justice system (CJS) in Pennsylvania. Costs impacting 3 principal areas of the CJS are examined: opioid-related arrests, court costs, and incarceration. Analysis of the state-level CJS is our main focus; no local-level costs are included. Through this examination, costs of the opioid crisis for the period of 2007 to 2016 were estimated using opioid costs for 2006 as a baseline. Total costs to the Pennsylvania CJS during this period were over $526 million, with most of that accounted for by state corrections. Opioid-related trends in arrests, court proceedings, and incarceration were not sufficiently well documented to allow for rigorous analysis in earlier periods, and this was the primary limitation to our analysis.

The economic burden of the opioid epidemic on states: the case of Medicaid

The societal burden of opioid use disorder (OUD) is considerable and contributes to increased healthcare costs and overdose deaths. However, the burden is not well understood. The purpose of this analysis is to estimate the state Medicaid programs' costs for treating OUD and how these costs have changed over time. We used data from the Medicaid Analytic eXtract files from 17 states between 1999 and 2013 to examine the healthcare costs associated with OUD. Inpatient, outpatient, and prescription medication costs related to the treatment of OUD were included, as were excess costs for other healthcare services (eg, general medical care) for individuals with OUD relative to a comparison group of individuals without OUD matched on age, sex, and state. We then extrapolated our results to the entire US Medicaid population using population-based sample weights. All costs were adjusted for inflation and are reported in 2017 US dollars. During our study period, the number of patients who were diagnosed with OUD increased 378%, from 39,109 (0.21% of total Medicaid enrollment) in 1999 to 186,979 (0.60% of total Medicaid enrollment) in 2013 in our 17-state sample. Even after adjusting for inflation, total Medicaid costs associated with OUD more than tripled during this time, reaching more than $3 billion in 2013, from $919 million in 1999. Most of this growth was due to excess non-OUD treatment costs for patients with OUD, which increased 363% over the period; the rate of growth is triple the expenditures for OUD treatment services. When the results were extrapolated to the entire United States, the Medicaid costs associated with OUD increased from more than $2 billion in 1999 to more than $8 billion in 2013. The total cumulative costs that were associated with OUD for this extrapolated 50-state sample over a 15-year time period amounts to more than $72.4 billion. OUD imposes considerable financial burden on state Medicaid programs, and the burden is increasing over time.

Availability and Cost of Naloxone Nasal Spray at Pharmacies in Philadelphia, Pennsylvania, 2017

IMPORTANCE

Despite the increasingly important role of pharmacies in the implementation of naloxone access laws, there is limited information on the impact of such laws at the local level.

OBJECTIVE

To evaluate the availability (with or without a prescription) and cost of naloxone nasal spray at pharmacies in Philadelphia, Pennsylvania, following a statewide standing order enacted in Pennsylvania in August 2015 to allow pharmacies to dispense naloxone without a prescription.

DESIGN, SETTING, AND PARTICIPANTS

A survey study was conducted by telephone of all pharmacies in Philadelphia between February and August 2017. Pharmacies were geocoded and linked with the American Community Survey (2011-2015) to obtain information on the demographic characteristics of census tracts and the Medical Examiner's Office of the Philadelphia Department of Public Health to derive information on the number of opioid overdose deaths per 100 000 people for each planning district. Data were analyzed from March 2018 to February 2019.

MAIN OUTCOMES AND MEASURES

Availability and out-of-pocket cost of naloxone nasal spray (with or without a prescription) at Philadelphia pharmacies overall and by pharmacy and neighborhood characteristics.

RESULTS

Of 454 eligible pharmacies, 418 were surveyed (92.1% response rate). One in 3 pharmacies (34.2%) had naloxone nasal spray in stock; of these, 61.5% indicated it was available without a prescription. There were significant differences in the availability of naloxone by pharmacy type and neighborhood characteristics. Naloxone was both more likely to be in stock (45.9% vs 27.8%; difference, 18.0%; 95% CI, 8.3%-27.8%; P < .001) and available without a prescription (80.6% vs 42.2%; difference, 38.4%; 95% CI, 23.0%-53.8%; P < .001) in chain stores than in independent stores. Naloxone was also less likely to be available in planning districts with very elevated rates of opioid overdose death (≥50 per 100 000 people) compared with those with lower rates (31.1% vs 38.5%). The median (interquartile range) out-of-pocket cost among pharmacies offering naloxone without a prescription was $145 ($119-$150); costs were greatest in independent pharmacies and planning districts with elevated rates of opioid overdose death.

CONCLUSIONS AND RELEVANCE

Despite the implementation of a statewide standing order in Pennsylvania more than 3 years prior to this study, only one-third of Philadelphia pharmacies carried naloxone nasal spray and many also required a physician's prescription. Efforts to strengthen the implementation of naloxone access laws and better ensure naloxone supply at local pharmacies are warranted, especially in localities with the highest rates of overdose death.

Impact of Abuse Deterrent Formulations of Opioids in Patients With Chronic Pain in the United States: A Cost-Effectiveness Model

OBJECTIVE

Opioid abuse is a significant public health problem in the United States. We evaluate the clinical effectiveness and economic impact of abuse-deterrent formulations (ADF) of opioids relative to non-ADF opioids in preventing abuse.

METHODS

We developed a cost-effectiveness model simulating 2 cohorts of 100 000 noncancer, chronic-pain patients newly prescribed either ADF or non-ADF extended-release (ER) opioids and followed them over 5 years, tracking new events of opioid abuse and opioid-related overdose deaths in addition to tracking 5-year cumulative costs of therapeutic use and abuse of ADF and non-ADF opioids. Patients in each cohort entered the model for therapeutic opioid use from where they could continue in that pathway, discontinue opioid use, or abuse opioids or die of opioid overdose-related or unrelated causes. In addition, one-way sensitivity and scenario analysis were conducted.

RESULTS

Over a 5-year time period, using ADF opioids prevented an additional 2300 new cases of opioid abuse at an additional cost of approximately $535 million to the healthcare sector. Threshold analyses showed that a 40% decrease in ADF opioid costs was required to attain cost neutrality between the 2 cohorts, whereas a 100% effectiveness in abuse reduction still did not result in cost neutrality. A 43% decrease in diversion with ADFs relative to non-ADFs was required to attain cost neutrality. Including a societal perspective produced results directionally similar to the base-case analysis findings.

CONCLUSION

ADF opioids have the potential to prevent new cases of opioid abuse, but at substantially higher costs to the health system.

Association of Pharmaceutical Industry Marketing of Opioid Products With Mortality From Opioid-Related Overdoses

IMPORTANCE

Prescription opioids are involved in 40% of all deaths from opioid overdose in the United States and are commonly the first opioids encountered by individuals with opioid use disorder. It is unclear whether the pharmaceutical industry marketing of opioids to physicians is associated with mortality from overdoses.

OBJECTIVE

To identify the association between direct-to-physician marketing of opioid products by pharmaceutical companies and mortality from prescription opioid overdoses across US counties.

DESIGN, SETTING, AND PARTICIPANTS

This population-based, county-level analysis of industry marketing information used data from the Centers for Medicare & Medicaid Services Open Payments database linked with data from the Centers for Disease Control and Prevention on opioid prescribing and mortality from overdoses. All US counties were included, with data on overdoses from August 1, 2014, to December 31, 2016, linked to marketing data from August 1, 2013, to December 31, 2015, using a 1-year lag. Statistical analyses were conducted between February 1 and June 1, 2018.

MAIN OUTCOMES AND MEASURES

County-level mortality from prescription opioid overdoses, total cost of marketing of opioid products to physicians, number of marketing interactions, opioid prescribing rates, and sociodemographic factors.

RESULTS

Between August 1, 2013, and December 31, 2015, there were 434 754 payments totaling $39.7 million in nonresearch-based opioid marketing distributed to 67 507 physicians across 2208 US counties. After adjustment for county-level sociodemographic factors, mortality from opioid overdoses increased with each 1-SD increase in marketing value in dollars per capita (adjusted relative risk, 1.09; 95% CI, 1.05-1.12), number of payments to physicians per capita (adjusted relative risk, 1.18; 95% CI, 1.14-1.21, and number of physicians receiving marketing per capita (adjusted relative risk, 1.12; 95% CI, 1.08-1.16). Opioid prescribing rates also increased with marketing and partially mediated the association between marketing and mortality.

CONCLUSIONS AND RELEVANCE

In this study, across US counties, marketing of opioid products to physicians was associated with increased opioid prescribing and, subsequently, with elevated mortality from overdoses. Amid a national opioid overdose crisis, reexamining the influence of the pharmaceutical industry may be warranted.

Recreational marijuana legalization and prescription opioids received by Medicaid enrollees

OBJECTIVES

Medical marijuana use may substitute prescription opioid use, whereas nonmedical marijuana use may be a risk factor of prescription opioid misuse. This study examined the associations between recreational marijuana legalization and prescription opioids received by Medicaid enrollees.

METHODS

State-level quarterly prescription drug utilization records for Medicaid enrollees during 2010-2017 were obtained from Medicaid State Drug Utilization Data. The primary outcome, opioid prescriptions received, was measured in three population-adjusted variables: number of opioid prescriptions, total doses of opioid prescriptions in morphine milligram equivalents, and related Medicaid spending, per quarter per 100 enrollees. Two difference-in-difference models were used to test the associations: eight states and DC that legalized recreational marijuana during the study period were first compared among themselves, then compared to six states with medical marijuana legalized before the study period. Schedule II and III opioids were analyzed separately.

RESULTS

In models comparing eight states and DC, legalization was not associated with Schedule II opioid outcomes; having recreational marijuana legalization effective in 2015 was associated with reductions in number of prescriptions, total doses, and spending of Schedule III opioids by 32% (95% CI: (-49%, -15%), p = 0.003), 30% ((-55%, -4.4%), p = 0.027), and 31% ((-59%, -3.6%), p = 0.031), respectively. In models comparing eight states and DC to six states with medical marijuana legalization, recreational marijuana legalization was not associated with any opioid outcome.

CONCLUSIONS

No evidence suggested that recreational marijuana legalization increased prescription opioids received by Medicaid enrollees. There was some evidence in some states for reduced Schedule III opioids following the legalization.

Physicians as Mediators of Health Policy: Acceptance of Medicaid in the Context of Buprenorphine Treatment

Increasing numbers of individuals with opioid use disorder (OUD) are insured by Medicaid. Little is known about whether providers of buprenorphine, an evidence-based OUD pharmacotherapy, accept this type of payment. Data are scant regarding whether Medicaid acceptance varies by physician and state-level characteristics. To address these gaps, national survey data from 1174 buprenorphine-prescribing physicians (BPPs) and state characteristics were examined in a multi-level model of Medicaid acceptance. Only 52.0% of BPPs accepted Medicaid for buprenorphine-related office visits. Specialists in addiction and psychiatry were significantly less likely to accept Medicaid than other specialties, as were BPPs delivering buprenorphine in individual medical practice. Perceived adequacy of Medicaid reimbursement was positively associated with accepting Medicaid. Medicaid acceptance was not associated with states' implementation of the Medicaid expansion. Individuals who are covered by Medicaid may face barriers to accessing buprenorphine treatment, which has high public health significance given the ongoing opioid epidemic.

The Prevalence and Cost of Medicare Beneficiaries Diagnosed and At Risk for Opioid Abuse, Dependence, and Poisoning

BACKGROUND

Reliance on prescription opioids to manage pain has been associated with increases in diversion, overdose, and addiction. Prevalence of misuse and abuse has been shown to be higher among government-insured populations than commercially insured populations. However, the prevalence and costs of misuse/abuse among the Medicare fee-for-service (FFS) population has not been studied.

OBJECTIVES

To (a) determine the prevalence and costs of prescription opioid misuse/abuse and (b) evaluate the prevalence and costs associated with those identified as at risk for opioid misuse/abuse in Medicare FFS beneficiaries.

METHODS

This retrospective case-control study used Medicare claims data for the calendar years of 2010 and 2011 and included Medicare beneficiaries aged at least 18 years. The index date was the date of first diagnosed misuse/abuse or at risk for abuse and had to occur between July 1, 2010, and June 30, 2011, and beneficiaries had to have at least 6 months continuous eligibility before and after the index date. Matching (1:1) was used for comparing opioid misusers/abusers with nonabuser controls, as well as comparing patients at risk for opioid abuse with controls not at risk for abuse. Controls were matched to cases by gender, age, disability, and geographic region. The index date of the control patient was set equal to the index date of the matched case.

RESULTS

Prevalence of misuse/abuse in the Medicare FFS population was 13.1 per 1,000 persons, with the majority among patients receiving Medicare based on disability (76.2%). The prevalence of at risk for misuse/abuse was 117.4 per 1,000 persons. Approximately half of the Medicare FFS patients used an opioid. Overall total annual unadjusted mean costs of health care resources were significantly greater for abusers than for matched controls ($46,194 vs. $21,964; P < 0.0001), with a mean annual excess cost of $24,230. The overall total adjusted 6-month post-index mean costs of health care resources for abusers was significantly greater than that of matched controls ($33,942 vs. $10,754; P < 0.0001), with a mean excess cost of $23,188.

CONCLUSIONS

The prevalence of diagnosed abuse among Medicare FFS population (13.1 per 1,000 persons) was higher than other payer groups studied using similar ICD-9-CM codes, and the majority of abuse was among those receiving Medicare based on disability (76.2%). The prevalence of at-risk abuse was 9 times higher than the prevalence of diagnosed abuse. As with other studies, health care resource utilization and costs were significantly greater for diagnosed abuse than matched controls.

Internalized stigma and its correlates among treatment seeking opium users in India: A cross-sectional observational study

Opium has been used in India since ancient times for social, recreational, religious and medicinal purposes. Opium users seem to constitute a distinct sub-population among opioid users, who have minimal complications, better functioning and socio-cultural acceptance. Prominent levels of stigma have been reported against people who use opioid drugs, but the same cannot be extrapolated to opium users. There is a vast number of opium users in India, and it is prudent to understand the stigma faced by them to better address their problems. Hence, in the current study we aimed to assess the internalized stigma and its correlates among opium users who seek treatment at a tertiary care drug treatment centre in North India. 117 adult male participants having opioid dependence (opium being the most common opioid in last 3 months) were assessed using Internalized Stigma of Mental Illness (ISMI) scale - Hindi version. The stigma scores were in the mild to moderate range, which was less than that found in previous studies among heroin and alcohol users in similar setting. Moreover, higher stigma scores were associated with lower educational status and higher proportions of income spent on substances. This is the first study to document stigma among opium users. Further research needs to be conducted to understand the determinants of stigma in this population.

Clinical effectiveness of pharmacy-led versus conventionally delivered antiviral treatment for hepatitis C in patients receiving opioid substitution therapy: a study protocol for a pragmatic cluster randomised trial

INTRODUCTION

Hepatitis C virus (HCV) infection affects 0.7% of the general population, and up to 40% of people prescribed opioid substitution therapy (OST) in Scotland. In conventional care, less than 10% of OST users are tested for HCV and less than 25% of these initiate treatment. Community pharmacists see this group frequently to provide OST supervision. This study examines whether a pharmacist-led 'test & treat' pathway increases cure rates for HCV.

METHODS AND ANALYSIS

This protocol describes a cluster-randomised trial where 60 community pharmacies provide either conventional or pharmacy-led care. All pharmacies offer dried blood spot testing (DBST) for HCV. Participants have attended the pharmacy for OST for 3 months; are positive for HCV genotype 1 or 3; are not co-infected with HIV and/or hepatitis B; have no decompensated liver disease; are not pregnant. For conventional care, pharmacists refer HCV-positive participants to a local centre for assessment. In the pharmacy-led arm, pharmacists assess participants themselves in the pharmacy. Drug prescribing is by nurse prescribers (conventional arm) or pharmacist prescribers (pharmacy-led arm). Treatment in both arms is delivered as daily modified directly observed therapy in a pharmacy. Primary trial outcome is number of sustained virological responses at 12 weeks after treatment completion. Secondary trial outcomes are number of tests taken; treatment uptake; completion; adherence; re-infection. An economic evaluation will assess potential cost-effectiveness. Qualitative research interviews with clients and health professionals assess acceptability of a pharmacist-led pathway.

ETHICS AND DISSEMINATION

This protocol has been ethically approved by the East of Scotland Research Ethics Committee 2 (15/ES/0086) and complies with the Declaration of Helsinki and principles of Good Clinical Practice. Caldicott guardian approval was given on 16 December 2016 to allow NHS Tayside to pass information to the cluster community pharmacies about the HCV test status of patients that they are seeing to provide OST supervision. NHS R&D approvals have been obtained from each health board taking part in the study. Informed consent is obtained before study enrolment and only anonymised data are stored in a secured database, enabling an audit trail. Results will be submitted to international peer-reviewed journals and presented at international conferences.

The Economic Burden of Abuse of Prescription Opioids: A Systematic Literature Review from 2012 to 2017

BACKGROUND

Abuse of prescription opioids [opioid use disorder (OUD), poisoning, and fatal and non-fatal overdose] is a public health and economic challenge that is associated with considerable morbidity and mortality in the USA and globally.

OBJECTIVE

To systematically review and summarize the health economics literature published over the last 5 years that describes the economic burden of abuse of prescription opioids.

METHODS

Findings from searches of databases including MEDLINE, Embase, and Cochrane CENTRAL as well as hand searches of multiple conference abstracts were screened against predefined inclusion criteria to identify studies reporting cost and healthcare resource utilization (HRU) data associated with abuse of prescription opioids.

RESULTS

A total of 49 unique studies were identified. Most of the studies examined direct costs and HRU, which were substantially higher for abusers of prescription opioids than non-abuser controls in several matched cohort analyses (US$20,343-US$28,718 vs US$9716-US$14,079 for mean direct combined annual healthcare costs reported in 6 studies). Although only a small number of studies reported indirect costs, these findings suggest a high societal burden related to productivity losses, absenteeism, morbidity, and mortality among those who abuse opioids. Studies of medication-assisted treatment demonstrated that factors such as adherence, dose, formulation (film or tablet), and relapse during treatment, were associated with direct costs and HRU among treated patients.

CONCLUSIONS

This systematic literature review shows that abuse of prescription opioids is characterized by substantial direct healthcare costs, medical utilization, and related societal costs. Future research should further investigate the indirect costs of opioid abuse.

The role of managed care professionals and pharmacists in combating opioid abuse

Substance misuse is a critical and costly public health problem in the United States. Data as of 2016 show 11,517 cases of opioid analgesic misuse, with the majority (6924 cases) related to hydrocodone misuse. Substance misuse impacts our society significantly with high costs related to healthcare, crime, and lost productivity. Opioid analgesic pain relievers are one of the most prescribed classes of medications and are among the most common drugs related to misuse. Increases in emergency department visits of over 200% have been associated with a dramatic surge in written prescriptions for opioid pain relievers. Mortality with opioid misuse has increased dramatically, with 2016 statistics demonstrating 42,249 deaths from any opioid; 15,469 heroin-related deaths; 14,487 deaths related to natural and semi-synthetic prescription agents; 19,413 deaths caused by mainly illicit use of synthetics (mostly fentanyl); and 3373 deaths related to methadone use. Per the Centers for Disease Control and Prevention (CDC), 3 of 5 drug overdoses are from an opioid, such as heroin, morphine, and prescription pain relievers. In addition, the expenses associated with drug use disorders are comparable to the costs of other chronic diseases, such as diabetes. Policymakers, criminal justice officials, and healthcare providers consider illicit drug and opioid misuse a national epidemic that must be addressed more strongly to improve pain management in the United States, optimize patient outcomes, and decrease unlawful drug use for pain relief.

Introduction to the opioid epidemic: the economic burden on the healthcare system and impact on quality of life

Opioid analgesics are commonly used to treat acute and chronic pain; in 2016 alone, more than 60 million patients had at least 1 prescription for opioid analgesics filled or refilled. Despite the ubiquitous use of these agents, the effectiveness of long-term use of opioids for chronic noncancer pain management is questionable, yet links among long-term use, addiction, and overdose deaths are well established. Because of overprescribing and misuse, an opioid epidemic has developed in the United States. The health and economic burdens of opioid abuse on individuals, their families, and society are substantial. Part 1 of this supplement will provide a background on the burden of pain and the impact of opioid abuse on individuals, their families, and society; the attempts to remedy this burden through prescription opioid use; and the eventual downward spiral into the current opioid epidemic, including an overview of opioid analgesics and opioid use disorder and the rise in opioid-related deaths.

Healthcare utilization and costs associated with treatment for opioid dependence

OBJECTIVE

Opioid use disorder (OUD) can be managed with medication assisted therapy (MAT) (methadone [MET], buprenorphine [BUP], or extended-release naltrexone [XR-NTX]) or counseling alone (non-pharmacological therapy [NPT]). The objective of this study was to evaluate healthcare resource utilization and costs associated with XR-NTX compared with alternative treatments for opioid dependence.

METHODS

Adults with a diagnosis of opioid dependence who initiated treatment with XR-NTX, BUP, MET, or NPT between January 1, 2011 and December 31, 2014 were identified in the Truven Health MarketScan Commercial administrative claims database. Healthcare resource utilization, costs (inpatient [IP], emergency department [ED], outpatient [OP], and pharmacy) and adherence were evaluated for each cohort during 12-month baseline and follow-up periods.

RESULTS

A total of 29,235 patients were included in the analysis; 1,041, 20,566, 745, and 6,883 received XR-NTX, BUP, MET, and NPT, respectively. Patients in the XR-NTX cohort were significantly younger and had more comorbidities compared with the other cohorts. Patients in the XR-NTX group had the largest percentage decrease in IP and ED utilization and costs from baseline to follow-up. OP and pharmacy costs increased significantly from baseline to follow-up for all cohorts. Overall, there was no significant change in total healthcare costs for the XR-NTX group, whereas the costs increased significantly for other groups (BUP = +43%, MET = +47.7%, NPT = +38.8%).

CONCLUSIONS

Healthcare resource utilization and costs increased from baseline to follow-up in BUP, MET, and NPT patients, whereas patients receiving XR-NTX experienced no such increase. This analysis suggests there may be economic value in the use of XR-NTX for OUD.

State-Targeted Funding and Technical Assistance to Increase Access to Medication Treatment for Opioid Use Disorder

OBJECTIVE

As the United States grapples with an opioid epidemic, expanding access to effective treatment for opioid use disorder is a major public health priority. Identifying effective policy tools that can be used to expand access to care is critically important. This article examines the relationship between state-targeted funding and technical assistance and adoption of three medications for treating opioid use disorder: oral naltrexone, injectable naltrexone, and buprenorphine.

METHODS

This study draws from the 2013-2014 wave of the National Drug Abuse Treatment System Survey, a nationally representative, longitudinal study of substance use disorder treatment programs. The sample includes data from 695 treatment programs (85.5% response rate) and representatives from single-state agencies in 49 states and Washington, D.C. (98% response rate). Logistic regression was used to examine the relationships of single-state agency targeted funding and technical assistance to availability of opioid use disorder medications among treatment programs.

RESULTS

State-targeted funding was associated with increased program-level adoption of oral naltrexone (adjusted odds ratio [AOR]=3.14, 95% confidence interval [CI]=1.49-6.60, p=.004) and buprenorphine (AOR=2.47, 95% CI=1.31-4.67, p=.006). Buprenorphine adoption was also correlated with state technical assistance to support medication provision (AOR=1.18, 95% CI=1.00-1.39, p=.049).

CONCLUSIONS

State-targeted funding for medications may be a viable policy lever for increasing access to opioid use disorder medications. Given the historically low rates of opioid use disorder medication adoption in treatment programs, single-state agency targeted funding is a potentially important tool to reduce mortality and morbidity associated with opioid disorders and misuse.
