Prescription Disposal Practices: A 2-Year Ecological Study of Drug Drop Box Donations in Appalachia

Increasing Uptake of Prescription Drug Take-Back Boxes: Eliciting Preferences and Applying the Theory of Planned Behavior to Predict Use

This study assesses adults' perceptions of and predictors of intention to use prescription drug take-back boxes. This mixed methods study utilized focus groups and an online survey to examine factors related to intention to use a prescription drug take-back box. This study was conducted in [State] during the spring and summer of 2018. Themes identified in focus group data included the importance of take-back box location, benefits of take-back box use (such as reducing opportunities for medication misuse), and barriers to take-back box use (such as lack of awareness, stigma associated with law enforcement). Survey results indicate that pharmacies are the most preferred take-back box location and that attitudes, subjective norms, and perceived behavioral control are statistically significant predictors of intention to use a take-back box. Results suggest that individuals are open to using take-back boxes in secure, convenient locations, but many are unaware of take-back boxes as an option for safe disposal. These findings have implications for health communication and policy efforts designed to increase the use of take-back boxes for prescription drug disposal.

Elucidating determinants of medication disposal programs at retail pharmacies in North Carolina

BACKGROUND

Pharmacy-based medication disposal programs is one approach to prevent diversion of unused prescription opioids.

OBJECTIVE(S)

The objective of this study was to assess the extent to which disposal programs have been implemented by retail pharmacies and identify determinants of implementation using the Consolidated Framework for Implementation Research.

METHODS

A sequential mixed-method design was used to examine implementation of medication disposal programs at pharmacies in Pitt County, NC. We conducted environmental scans of all retail pharmacies that served community members (N = 31) to assess the extent to which disposal programs had been implemented. Then, we conducted interviews with pharmacists (n = 15; 48.4%) to identify determinants of implementation. The following pharmacy types were represented in the completed interviews: corporate chain (n = 10), small chain (n = 1), independently owned and operated (n = 1), medical (n = 2), and government (n = 1).

RESULTS

We found that 32.3% of pharmacies (n = 10) had a medication disposal box and 12.9% (n = 4) had posted a flyer on medication disposal. Pharmacists perceived that patients benefit from disposal boxes and medication disposal is in their purview. Determinants of implementation included the cost of sustaining the intervention, polices of corporate and regional management, variable local control in the decision-making process to implement a disposal box, and experience with having a medication disposal box.

CONCLUSION

Our findings highlight one way in which pharmacists can have a vital role in preventing diversion of opioid analgesics and associated consequences. There is a need to expand disposal boxes at pharmacies to increase community member accessibility and use. Future research is needed to determine the cost-effectiveness of expanding the scale of disposal box implementation in community pharmacies.

Adherence to Opioid Prescribing Guidelines in a Statewide Surgical Quality Improvement Collaborative

INTRODUCTION

The opioid crisis is an ongoing crisis in the United States. Postoperative patients who receive opioid prescriptions have a 3%-7% risk of developing a chronic opioid abuse problem. This study aims to describe on-target opioid prescribing and use of multimodal pain management strategies 2 y after the implementation of a multicomponent quality improvement initiative across our statewide collaborative.

METHODS

From July 2020 to September 2021, we prospectively collected data on opioid-prescribing and multimodal strategies for 10 targeted procedures in general, gynecologic, and orthopedic surgery at three hospitals. Prescribing was on-target if a patient was prescribed ≤50 daily morphine milligram equivalents. Multimodal strategies were defined as two or more nonopioid adjuncts used within 48 h of surgery.

RESULTS

One thousand and eleven targeted procedures were performed with prescription data available for 993 cases. The on-target prescribing rate was 79.6% (n = 790), with general surgery 92.5% (n = 285), gynecology 84.9% (n = 331), and orthopedic surgery 59.0% (n = 174). Patients who received multimodal pain approaches were associated with interventions such as patient education, transversus abdominus plane block, and prescriptions for nonopioid analgesics at discharge. There was no evidence to support a difference in the use of multimodal pain control approaches between patients whose opioid prescribing was on-target or not (73.8% versus 77.3%, P = 0.30). At the first postoperative visit, data on continued opioid use were missing in 57.3% of patients, number of pills used was missing in 93.8%, and adequate pain control was missing in 52.8%.

CONCLUSIONS

On-target prescribing and multimodal strategies are common but vary by specialty. Additionally, postoperative pain control and opioid use are often not documented. To better match prescribing to patient needs, understanding patient-level and specialty-level opioid use is important.

Drug disposal deserts: An assessment of receptacle availability in Kentucky community pharmacies

PURPOSE

The purpose of this study was to describe the county-level availability of drug disposal receptacles in Kentucky community pharmacies and show the relationship between installed receptacles and opioid analgesic (OA)/controlled substance dispensing rates, stratifying where possible by urban-rural classification.

METHODS

Using 2020 data from the Kentucky All Schedule Prescription Electronic Reporting program and disposal receptacle data from the US Drug Enforcement Agency, county-level comparisons were made between number of receptacles and OA/controlled substance dispensing rates. Logistic and negative binomial regression models were used to assess for differences between rural/urban county designation and odds of ≥1 disposal receptacle and compare the rates of receptacles per dispensed OA dose in rural/urban counties.

FINDINGS

While rural counties saw higher OA and controlled substance dispensing rates, the majority (55.6%) of disposal receptacles were in urban locations. The odds of having at least 1 receptacle were higher in urban counties (OR 2.60, 95% CI: 1.15, 5.92) compared to rural. The estimated rate of disposal receptacles per million dispensed OA doses was found to be 0.47 (95% CI: 0.36, 0.61) in urban counties compared to 0.32 (95% CI: 0.25, 0.42) in rural counties, with an estimated rate ratio of 1.45 (95% CI: 1.01, 2.10).

CONCLUSIONS

A mismatch between the availability of county-level disposal receptacles in community pharmacies and the volume of dispensed OAs/controlled substances exists, resulting in fewer receptacles per dispensed OA in rural counties compared to urban counties. Future efforts are necessary to increase access to convenient disposal receptacles located in community pharmacies, particularly in rural communities.

Evaluating a health system-wide opioid disposal intervention distributing home-disposal bags

OBJECTIVE

To evaluate a health system-wide intervention distributing free home-disposal bags to surgery patients prescribed opioids.

DATA SOURCES AND STUDY SETTING

We collected patient surveys and electronic medical record data at an academic health system.

STUDY DESIGN

We conducted a prospective observational study. The bags were primarily distributed at pharmacies, though pharmacists delivered bags to some patients. The primary outcome was disposal of leftover opioids (effectiveness). Secondary outcomes were patient willingness to dispose and factors associated with disposal (effectiveness), recalling receipt of the bag (reach), and recalling receipt of bags and disposal over time (maintenance). We used a modified Poisson regression to evaluate the relative risk of disposal. Inverse probability of treatment weighting, based on propensity scores, was used to account for differences between survey responders and non-responders and reduce nonresponse bias.

DATA COLLECTION/EXTRACTION METHODS

From August 2020 to May 2021, we surveyed patients 2 weeks after discharge (allowing for home opioid use). Eligibility criteria were age ≥18, English being primary language, valid email address, hospitalization ≤30 days, discharge home, and an opioid prescription sent to a system pharmacy.

PRINCIPAL FINDINGS

We identified 5134 patients with 2174 completing the survey (response rate 42.3%). Among respondents, 1375 (63.8%) recalled receiving the disposal bag. Among 1075 respondents with leftover opioids, 284 (26.4%) disposed, 552 (51.3%) planned to dispose, 79 (7.4%) did not plan to dispose, 69 (6.4%) had undecided, and 91 (8.5%) had not considered disposal. Recalling receipt of the bag (incidence rate ratio [IRR] 1.25, 95% confidence interval [CI] 1.13-1.37) was positively associated with disposal. Patients who used opioids in the last year were less likely to dispose (IRR 0.82, 95% CI 0.73-0.93). Disposal rates remained stable over the study period while recalling receipt of bags trended up.

CONCLUSIONS

A pragmatic implementation of a disposal intervention resulted in lower disposal rates than prior trials.

Assessing Perceptions and Medication Disposal Habits in Rural Michigan

Background: Inadequate or inappropriate medication disposal is a public health concern that may lead to increased community risk of accidental poisonings, substance misuse, and environmental pollution. Objective: The study's primary objective was to assess medication disposal knowledge and practices of Michigan residents living in rural, underserved areas. Secondary objectives included determining baseline perceptions of at-home drug disposal kits and examining the impact of an educational video intervention on at-home drug disposal kit perceptions. Methods: To measure the objectives, an online 15-question survey was deployed to the general public via convenience sampling from local organizations working with drug disposal. The survey questions assessed medication disposal knowledge and practices in underserved, rural Michigan. Participant responses were assessed categorically and numerically. Results: Inclusion criteria were met by 97 survey participants. Results indicated that Michigan rural residents, regardless of various demographic factors, would benefit from increased drug disposal education. Specifically, at-home drug disposal kits and medication drop boxes have the highest need for additional education. Perceptions related to home disposal safety and ease of use improved significantly with an educational video intervention. Conclusion: All rural residents, regardless of demographics, would benefit from increased drug disposal education. A short, educational video can impact thoughts and attitudes related to at-home drug disposal kits. Similar interventions may be successful in other rural, underserved areas.

Promoting Disposal of Left-Over Opioids After Surgery in Rural Communities: A Qualitative Description Study

BACKGROUND

Patients rarely dispose of left-over opioids after surgery. Disposal serves as a primary prevention against misuse, overdose, and diversion. However, current interventions promoting disposal have mixed efficacy. Increasing disposal in rural communities could prevent or reduce the harms caused by prescription opioids.

AIMS

Identify barriers and facilitators to disposal in the rural communities of the United States Mountain West region.

METHODS

We conducted a qualitative description study with 30 participants from Arizona, Idaho, Montana, Nevada, Oregon, Utah, and Wyoming. We used a phronetic iterative approach combining inductive content and thematic analysis with deductive interpretation through the Precaution Adoption Process Model (PAPM).

RESULTS

We identified four broad themes: (a) awareness, engagement, and education; (b) low perceived risk associated with nondisposal; (c) deciding to keep left-over opioids for future use; and (d) converting decisions into action. Most participants were aware of the importance of disposal but perceived the risks of nondisposal as low. Participants kept opioids for future use due to uncertainty about their recovery and future treatments, breakdowns in the patient-provider relationship, chronic illness or pain, or potential future injury. The rural context, particularly convenience, cost, and environmental contamination, contributes to decisional burden.

CONCLUSIONS

We identified PAPM stage-specific barriers to disposal of left-over opioids. Future interventions should account for where patients are along the spectrum of deciding to dispose or not dispose as well as promoting harm-reduction strategies for those who choose not to dispose.

Determination of Albuterol and Montelukast Post-Expiry Drug Strength by HPLC

Background

Knowing the level of active ingredients in an expired drug is a matter of concern irrespective of its final disposition. This is also a matter of national security and defense as it has important implications on the nation’s stockpile of prescription medications. Current literature has limited information about the strength of expired medications and any relevant trends.

Objective

To utilize high performance liquid chromatography (HPLC) to determine the strength of selected drugs for asthma and chronic obstructive pulmonary disease (COPD) as a class of therapeutic agents commonly used in free clinics.

Methods

Samples from expired lots of montelukast and albuterol pharmaceutical products were analyzed for their levels of their respective active ingredients. Two HPLC methods were developed, validated, and applied to achieve this goal. Quantitative analysis of each drug was performed using two different reversed phase C18 columns with a linear gradient of acetonitrile in 0.1% aqueous formic acid at a flow rate of 1 mL/min for both methods. Detection wavelength for montelukast and albuterol was 280 and 277 nm, respectively.

Results

Expiry dates of analyzed batches ranged from 2003 to 2019. Despite the extended time range beyond expiry dates, levels of both drugs were relatively consistent and exceeded 90% of the listed strength in most analyzed lots.

Conclusions

Our results introduce a new perspective towards reducing the financial burden resulting from disposal of expired medications with retained strength. They also offer supporting evidence to extend the use of out-of-date montelukast and albuterol preparations at home and in free clinics.

Postoperative Opioid Prescribing, Use, and Disposal in Children

This article provides an overview of postoperative opioid prescribing, use, and disposal patterns in children and also identifies gaps in knowledge and areas for improvement. We present evidence that there is a need to tailor prescriptions to specific procedures to reduce the number of excess, unused prescription opioid pills in the home. We also explain the need to provide culturally competent care when managing a child's pain after surgery. Finally, we discuss the need for widespread provider and caregiver education about safe prescription opioid use, storage, and disposal.

Primary prevention of prescription opioid diversion: a systematic review of medication disposal interventions

Background: In the U.S., 50-75% of nonmedical users of prescription opioids obtain their pills through diversion by friends or relatives. Increasing disposal of unused opioid prescriptions is a fundamental primary prevention strategy in combatting the opioid epidemic.Objectives: To identify interventions for disposal of unused opioid pills and assess the evidence of their effectiveness on disposal-related outcomes.Methods: A search of four electronic databases was conducted (October 2019). We included all empirical studies, systematic literature reviews, and meta-analyses about study medication disposal interventions in the U.S. Studies of disposal interventions that did not include opioids were excluded. We abstracted data for the selected articles to describe the study design, and outcomes. Further, we assessed the quality of each study using the NIH Study Quality Assessment Tools.Results: We identified 25 articles that met our inclusion criteria. None of the 13 studies on drug take-back events or the two studies on donation boxes could draw conclusions about their effectiveness. Although studies on educational interventions found positive effects on knowledge acquisition, they did not find differences in disposal rates. Two randomized controlled trials on drug disposal bags found higher opioid disposal rates in their intervention arms compared to the control arms (57.1% vs 28.6% and 33.3%, p = .01; and 85.7% vs 64.9%, p = .03).Conclusions: Peer-reviewed publications on opioid disposal interventions are limited and either do not address effectiveness or have conflicting findings. Future research should address these limitations and further evaluate implementation and cost-effectiveness.

Rural Emergency Medical Service Providers Perceptions on the Causes of and Solutions to the Opioid Crisis: A Qualitative Assessment

Introduction:

The continuing opioid crisis poses unique challenges to remote and often under-resourced rural communities. Emergency medical service (EMS) providers serve a critical role in responding to opioid overdose for individuals living in rural or remote areas who experience opioid overdoses. They are often first at the scene of an overdose and are sometimes the only health care provider in contact with an overdose patient who either did not survive or refused additional care. As such, EMS providers have valuable perspectives to share on the causes and consequences of the opioid crisis in rural communities.

Methods:

EMS providers attending a statewide EMS conference serving those from greater Minnesota and surrounding states were invited to take a 2-question survey asking them to reflect upon what they believed to be the causes of the opioid crisis and what they saw as the solutions to the opioid crisis. Results were coded and categorized using a Consensual Qualitative Research approach.

Results:

EMS providers’ perceptions on causes of the opioid crisis were categorized into 5 main domains: overprescribing, ease of access, socioeconomic vulnerability, mental health concerns, and lack of resources and education. Responses focused on solutions to address the opioid crisis were categorized into 5 main domains: need for increased education, enhanced opioid oversight, increased access to treatment programs, alternative therapies for pain management, and addressing socioeconomic vulnerabilities.

Conclusion:

Along with the recognition that the opioid crisis was at least partially caused by overprescribing, rural EMS providers who participated in this study recognized the critical role of social determinants of health in perpetuating opioid-related harm. Participants in this study reported that education and increased access to treatment facilities and appropriate pain management, along with recognition of the role of social determinants of health in opioid dependency, were necessary steps to address the opioid crisis.

A Latent Class Analysis of Prevention Approaches Used to Reduce Community-Level Prescription Drug Misuse in Adolescents and Young Adults

The Substance Abuse and Mental Health Services Administration's Strategic Prevention Framework Partnerships for Success (PFS) program supports community-based organizations (CBOs) across the United States in implementing evidence-based prevention interventions to reduce substance use in adolescents and young adults. Little attention has been paid to how CBOs combine interventions to create comprehensive community-specific prevention approaches, or whether different approaches achieve similar community-level effects on prescription drug misuse (PDM). We used PFS evaluation data to address these gaps. Over 200 CBOs reported their prevention intervention characteristics, including strategy type (e.g., prevention education, environmental strategies) and number of unique interventions. Evaluation staff coded whether each intervention was an evidence-based program, practice, or policy (EBPPP). Latent Class Analysis of seven characteristics (use of each of five strategy types, use of one or more EBPPP, and number of interventions implemented) identified six prevention approach profiles: High Implementation EBPPP, Media Campaigns, Environmental EBPPP, High Implementation Non-EBPPP, Prevention Education, and Other Information Dissemination. All approaches except Media Campaigns and Other Information Dissemination were associated with significant reductions in community-level PDM. These approaches may need to be paired with other, more direct, prevention activities to effectively reduce PDM at the community level. However, similar rates of change in PDM across all 6 prevention approaches suggests only weak evidence favoring use of the other four approaches. Community-based evaluations that account for variability in implemented prevention approaches may provide a more nuanced understanding of community-level effects. Additional work is needed to help CBOs identify the most appropriate approach to use based on their target communities' characteristics and resources.

Predictors of Safe Prescription Opioid Storage and Participation in Drug Take-Back Events: Results from a Statewide Survey

Improper storage and disposal of prescribed opioids can lead to diversion or accidental poisonings. Studies of emergency department and cancer patients suggest prescription opioids are rarely stored securely or disposed of when unneeded. Safe storage and disposal practices reduce risks for others living in or visiting a household. The purpose of this study is thus to examine prescription opioid storage and participation in drug take-back events among Michigan adults. Participants (N = 702) were recruited through social media advertisements to complete an online survey in July and August 2018. Logistic regression was used to examine correlates of safe storage and disposal. 8.4% (n = 59) of participants reported always keeping opioids locked; 29.8% (n = 209) reported attending a drug take-back event. Black participants and those who believed that illegal drug use was a serious problem had greater odds of locking opioids; participants with higher levels of education or who knew someone who used heroin or misused prescription opioids had lesser odds of locking opioids. Age and race were associated with take-back event participation. Findings identify factors associated with safe prescription opioid storage/disposal and indicate safe storage/disposal seldom occurs. Education and provision of safe storage equipment should be designed for diverse ages, races/ethnicities, and levels of education. Drug take-back events not hosted by law enforcement may have broader appeal, as may those led by Black or other people of color. Wider use of drug donation boxes may facilitate increased disposal among those who do not wish to or cannot attend take-back events.

Modifiable Risk Factors Associated With Disposal of Unused Prescription Drugs by Parents of Adolescents

The safe disposal of unused medications is one primary prevention strategy to reduce nonmedical prescription drug use among adolescents. We sought to identify modifiable risk factors associated with disposal of unused prescription drugs by parents of adolescents residing in ten south central Kentucky counties with disposal programs. In the fall of 2017, 4148 parents of adolescents participated in an anonymous, paper-based survey. We conducted generalized logit mixed models adjusted for within-school clustering to assess the relationship between disposal behaviors and modifiable risk factors while controlling for respondents' sociodemographic characteristics. The analytic sample consisted of parents in households in which someone had been prescribed an opioid medication within the past 12 months (N = 627). Our findings indicated that almost 42% of parents reported disposing of unused prescription medication within the past 12 months, and the majority disposed of medications at home rather than using a disposal program. Parents who perceived that any, compared to none, of their child's close friends engaged in nonmedical prescription opioid use had higher odds of reporting use of a disposal program. Parents who were aware of disposal programs, compared to those who were not aware, had greater odds of using them, rather than not disposing at all or disposing unused prescription medications at home. Compared to parents who perceived prescription drugs to be hard for adolescents to obtain for nonmedical use, parents who believed that prescription drugs were easily accessible to adolescents for nonmedical use had lower odds of using disposal programs than disposing of medications at home. Collectively, our findings suggest that enhancing awareness of disposal programs, while addressing parents' perceptions of their children's peers' use of nonmedical prescription opioids, should be considered to facilitate the disposal of unused medications and optimize current public health prevention efforts related to adolescent nonmedical use of these drugs.

The Opioid-overdose Reduction Continuum of Care Approach (ORCCA): Evidence-based practices in the HEALing Communities Study

BACKGROUND

The number of opioid-involved overdose deaths in the United States remains a national crisis. The HEALing Communities Study (HCS) will test whether Communities That HEAL (CTH), a community-engaged intervention, can decrease opioid-involved deaths in intervention communities (n = 33), relative to wait-list communities (n = 34), from four states. The CTH intervention seeks to facilitate widespread implementation of three evidence-based practices (EBPs) with the potential to reduce opioid-involved overdose fatalities: overdose education and naloxone distribution (OEND), effective delivery of medication for opioid use disorder (MOUD), and safer opioid analgesic prescribing. A key challenge was delineating an EBP implementation approach useful for all HCS communities.

METHODS

A workgroup composed of EBP experts from HCS research sites used literature reviews and expert consensus to: 1) compile strategies and associated resources for implementing EBPs primarily targeting individuals 18 and older; and 2) determine allowable community flexibility in EBP implementation. The workgroup developed the Opioid-overdose Reduction Continuum of Care Approach (ORCCA) to organize EBP strategies and resources to facilitate EBP implementation.

CONCLUSIONS

The ORCCA includes required and recommended EBP strategies, priority populations, and community settings. Each EBP has a "menu" of strategies from which communities can select and implement with a minimum of five strategies required: one for OEND, three for MOUD, and one for prescription opioid safety. Identification and engagement of high-risk populations in OEND and MOUD is an ORCCArequirement. To ensure CTH has community-wide impact, implementation of at least one EBP strategy is required in healthcare, behavioral health, and criminal justice settings, with communities identifying particular organizations to engage in HCS-facilitated EBP implementation.

Developing a health communication campaign for disposal of unused opioid medications

INTRODUCTION

Communities throughout the United States have implemented medicine disposal programs to prevent diversion of unused opioid analgesics from homes but a general lack of awareness may contribute to low rates of utilization. The objective of this study was to develop and test community-based campaign messages promoting appropriate disposal of unused opioids at disposal programs.

METHODS

In Fall 2019, 491 residents (79% female, 97% White, mean age: 40 years) of five rural, Appalachian counties (3 in Kentucky and 2 in North Carolina) completed a web-based, experimental survey. Participants were randomly exposed to two of four messages and rated each message separately. A pretest-posttest design was utilized to assess change in beliefs about retaining unused prescription opioids in the home following exposure to message sets.

RESULTS

All messages favorably influenced participants' perceptions related to concerns and risks of retaining unused prescription opioids and importance of - and self-efficacy in disposing of unused opioid medications. After controlling for social and demographic characteristics and baseline beliefs in generalized linear mixed models, Message 1 outperformed other messages in increasing participants' concern about retaining unused prescription opioids in the home and Message 3 was most effective in increasing self-efficacy to dispose of unused prescription opioids.

CONCLUSIONS

Messages including young children and pictorially demonstrate how to dispose of medications may have the greatest impact on behavioral actions related to medication disposal. The findings from this study can be used to inform community-based campaigns to facilitate disposal of unused prescription opioids.

Latent Profiles of Health and Reproductive Risk and Protective Factors among Women in Appalachia

Women who use opiates and are involved in the criminal justice system in Appalachia may be prone to adverse health outcomes. In this study, we performed a latent class analysis of risk and protective factors on 400 drug-using women recruited from rural, Appalachian jails. A two-profile solution best fit the data. Both profiles evinced low levels of condom use, reproductive and physical health screens, and STD history. However, the primary substantive difference between the profiles was partner risk behavior: the higher risk class had main male partners with histories of injection drug use and incarceration. Results suggest that interventions need to be tailored to unique profiles of risk and protective factors, which should include taking partner risk into consideration.

Encouraging Disposal of Unused Opioid Analgesics in Appalachia

The Appalachian region has been disproportionately impacted by the opioid epidemic. This study, informed by the Health Belief Model (HBM), explored Appalachian community members' perspectives on prescription opioid misuse and community-based programs to dispose of unused opioid analgesics. In 2018, we conducted ten focus groups (n=94 participants) in 5 Appalachian counties. Thirteen themes across 5 of the HBM constructs emerged from our analysis. Participants perceived that their communities are susceptible to the harms associated with opioid misuse, these harms are serious, suggesting they could be motivated to change disposal behaviors. Many participants recognized the benefit to disposing of unused prescription opioids including protecting household members from misusing and protecting the home from robbery. Nevertheless, participants identified barriers to proper disposal, including keeping the medications "just in case" for future ailments and the location of drop boxes near law enforcement (due to deep-seated mistrust of law enforcement agencies). Self-efficacy was difficult to assess as many participants were completely unaware of the presence of dropboxes in the community and also expressed concerns about the inconvenience of proper disposal using dropboxes These findings have implications for developing community-based campaign messages promoting proper disposal of unused opioids.

A Dissemination and Implementation Science Approach to the Epidemic of Opioid Use Disorder in the United States

PURPOSE OF REVIEW

This review aims to (1) conceptualize the complexity of the opioid use disorder epidemic using a conceptual model grounded in the disease continuum and corresponding levels of prevention and (2) summarize a select set of interventions for the prevention and treatment of opioid use disorder.

RECENT FINDINGS

Epidemiologic data indicate non-medical prescription and illicit opioid use have reached unprecedented levels, fueling an opioid use disorder epidemic in the USA. A problem of this magnitude is rooted in multiple supply- and demand-side drivers, the combined effect of which outweighs current prevention and treatment efforts. Multiple primary, secondary, and tertiary prevention interventions, both evidence-informed and evidence-based, are available to address each point along the disease continuum-non-use, initiation, dependence, addiction, and death. If interventions grounded in the best available evidence are disseminated and implemented across the disease continuum in a coordinated and collaborative manner, public health systems could be increasingly effective in responding to the epidemic.

Evaluating the implementation and effectiveness of a multi-component intervention to reduce post-surgical opioid prescribing: study protocol of a mixed-methods design

INTRODUCTION

Opioids prescribed after surgery accounted for 5% of the 191 million opioid prescriptions filled in 2017. Approximately 80% of the opioid pills prescribed by surgical care providers remain unused, leaving a substantial number of opioids available for non-medical use. We developed a multi-component intervention to address surgical providers' role in the overprescribing of opioids. Our study will determine effective strategies for reducing post-surgical prescribing while ensuring adequate post-surgery patient-reported pain-related outcomes, and will assess implementation of the strategies.

METHODS AND ANALYSIS

The Minimising Opioid Prescribing in Surgery study will implement a multi-component intervention, in an Illinois network of six hospitals (one academical, two large community and three small community hospitals), to decrease opioid analgesics prescribed after surgery. The multi-component intervention involves four domains: (1) patient expectation setting, (2) baseline assessment of opioid use, (3) perioperative pain control optimisation and (4) post-surgical opioid minimisation. Four surgical specialities (general, orthopaedics, urology and gynaecology) at the six hospitals will implement the intervention. A mixed-methods approach will be used to assess the implementation and effectiveness of the intervention. Data from the network's enterprise data warehouse will be used to evaluate the intervention's effect on post-surgical prescriptions and a survey will collect pain-related patient-reported outcomes. Intervention effectiveness will be determined using a triangulation design, mixed-methods approach with staggered speciality-specific implementation for contemporaneous control of opioid prescribing changes over time. The Consolidated Framework for Implementation Research will be used to evaluate the site-specific contextual factors and adaptations to achieve implementation at each site.

ETHICS AND DISSEMINATION

The study aims to identify the most effective hospital-type and speciality-specific intervention bundles for rapid dissemination into our 56-hospital learning collaborative and in hospitals throughout the USA. All study activities have been approved by the Northwestern University Institutional Review Board (ID STU00205053).

Inappropriate opioid prescription after surgery

Worldwide, the use of prescription opioid analgesics more than doubled between 2001 and 2013, with several countries, including the USA, Canada, and Australia, experiencing epidemics of opioid misuse and abuse over this period. In this context, excessive prescribing of opioids for pain treatment after surgery has been recognised as an important concern for public health and a potential contributor to patterns of opioid misuse and related harm. In the second paper in this Series we review the evolution of prescription opioid use for pain treatment after surgery in the USA, Canada, and other countries. We summarise evidence on the extent of opioid overprescribing after surgery and its potential association with subsequent opioid misuse, diversion, and the development of opioid use disorder. We discuss evidence on patient, physician, and system-level predictors of excessive prescribing after surgery, and summarise recent work on clinical and policy efforts to reduce such prescribing while ensuring adequate pain control.

Understanding Differences in Types of Opioid Prescriptions Across Time and Space: A Community-Level Analysis

For the better part of the 21st century, opioid abuse and related consequences have beleaguered the United States. Effectively fighting the crisis may require a better understanding of potential differences among the types of opioids available as treating them as one homogeneous group may mask emerging trends and conflate more benign ones with those more troubling. The purpose of our study is to investigate changes in prescribing patterns of four groups of opioids (hydrocodone, oxycodone, fentanyl, and other) and how community-level factors explain their variation over time. We use a census tract–level data set with population, concentrated disadvantage, and prescription drug monitoring payment variables to address our goals. Findings show disparate prescribing patterns among the four types of opioids and considerable differences in the community factors that predict their change. Implications for future research and interventions follow.

Diffusion of medication drop-boxes in North Carolina from 2007 to 2016

INTRODUCTION

A permanent drug donation box ("drop-box") is one strategy implemented in communities across the United States to reduce the availability of excess controlled medications, including prescription opioids, for diversion. The objective of this study was to examine correlates of the diffusion and implementation of drop-boxes in North Carolina.

METHODS

We assessed the number and location of drop-boxes implemented in North Carolina. Cox proportional hazards models were used to examine covariates associated with drop-box implementation in NC counties (n = 100) between 2007 and 2016.

RESULTS

There were 311 drop-boxes implemented in 91 (out of 100) counties. Most drop-boxes were in law enforcement agencies (78.8%) and a growing number were in pharmacies (14.5%). Counties with a higher percentage of whites, more educated residents, a substance abuse prevention coalition, higher rates of controlled medications dispensed and prescription opioid overdose, and that were Appalachian were more likely to be early adopters. Rural counties were less likely to have a drop-box. In the multivariate model, only higher rate of controlled medicines dispensed was significant.

CONCLUSIONS

A growing number of drop-boxes are being implemented in law enforcement offices and pharmacies. Given that communities with higher rates of controlled medication dispensing likely have the highest need for disposal opportunities, it is promising that they are early adopters of drop-boxes. Future research should assess the effectiveness of drop-boxes as they become more widespread in a variety of locations.

A systematic review of strategies to improve appropriate use of opioids and to reduce opioid use disorder and deaths from prescription opioids

Background

Abuse of prescription opioids is a serious problem in North America.

Aims

The aim of this study was to conduct a systematic review of peer-reviewed and grey literature to examine existing strategies aimed at improving the appropriate use of prescription opioids and/or reducing the misuse, abuse, and diversion of these drugs.

Methods

The following electronic databases were searched to September 2015 without language restrictions: MEDLINE, EMBASE, PsycINFO, and CINAHL; the grey literature was searched to May 2014. Reference lists of retrieved papers were also searched. Studies were eligible if a strategy was implemented and its impact on at least one of the primary outcomes of interest (appropriate prescription opioid use; misuse, abuse, opioid use disorder, diversion; overdose) was measured. Standardized, prepiloted forms were used for relevance screening, quality appraisal, and data extraction.

Results

A total of 65 studies that assessed 66 distinct strategies were identified. Due to the heterogeneity of the strategies, a qualitative synthesis was conducted. Many studies combined more than one type of strategy and measured various types of outcomes. The strategies with most promising results involved education, clinical practices, collaborations, prescription monitoring programs, public campaigns, opioid substitution programs, and naloxone distribution. We also found strategies that had some unintended consequences after implementation.

Conclusions

Our review identified successful strategies that have been implemented and evaluated in various jurisdictions. There is a need to replicate and disseminate these strategies where the problem of prescription opioid misuse and abuse has taken a toll on society.

Nonmedical Prescription Drug Use among Adolescents: Global Epidemiological Evidence for Prevention, Assessment, Diagnosis, and Treatment

Purpose of review

This paper reviews the most recent epidemiological evidence on adolescent NMPD use. Particular attention is given to prevention, assessment and diagnosis of disorder, and treatment.

Recent findings

While international in scope, global evidence is only available for NMPD use, morbidity and mortality estimates. Prevention strategies, assessment and treatment are U.S.-centric. The literature on prevention strategies lacks high-quality evidence. Assessment, diagnosis and treatment of NMPD use disorder have more robust evidence bases. Despite this, screening for NMPD (and other drug) use disorders is infrequent and insensitive, leading to incomplete treatment provision. Treatments are shown to be safe and effective, but disparities in provision prevent wide-scale amelioration of the adolescent NMPD use problem.

Summary

Mental health care professionals and primary care physicians with adolescent patient populations should become involved in preventative strategies mentioned in this review. Additionally, higher screening rates will lead to less downstream problems related to NMPD use.

A Multiyear Assessment of Public Response to a Statewide Drug Take-Back and Disposal Campaign, 2010 to 2012

This study is the first to analyze public response to a drug take-back program, the American Medicine Chest Challenge, in a single state over a period of 3 years (2010-2012). The study utilized a three-wave repeated cross-sectional design and an annual phone survey conducted with a representative sample of adults ( N = 906 in 2010, N = 907 in 2011, and N = 906 in 2012), which assessed exposure to the campaign, drug disposal behaviors, possible mediators of campaign effects (risk appraisal, personal agency, normative influence, and interpersonal talk), and potential confounders. Logistic regression and causal mediation analysis were employed to estimate confounder-adjusted direct and mediated effects of the campaign. Results showed that the campaign reached a sizable portion (50% to 60%) of state adults and that campaign exposure was associated with increased likelihood of having conversations with others about this topic. About 55% of all adults in the state reported taking at least one of the actions recommended by the campaign, and campaign exposure was associated with increased likelihood of disposing of prescription drugs at a drug collection day event (adjusted odds ratio = 4) and of talking to a child about the risks associated with prescription drug abuse (adjusted odds ratio = 2). The causal mediation analysis demonstrated that the campaign influenced audiences by reinforcing their efficacy to safely dispose of prescription drugs, but also potentially by stimulating conversations among community members about this topic. Drug take-back campaigns can be an effective mechanism to decrease the availability of prescription drugs in communities.

Unused opioid analgesics and drug disposal following outpatient dental surgery: A randomized controlled trial

BACKGROUND

Individuals who abuse prescription opioids often use leftover pills that were prescribed for friends or family members. Dental surgery has been identified as a common source of opioid prescriptions. We measured rates of used and unused opioids after dental surgery for a pilot program to promote safe drug disposal.

METHODS

We conducted a randomized controlled trial of opioid use patterns among patients undergoing surgical tooth extraction at a university-affiliated oral surgery practice. The primary objective was to describe opioid prescribing and consumption patterns, with the number of unused opioid pills remaining on postoperative day 21 serving as the primary outcome. The secondary aim was to measure the effect of a behavioral intervention (informing patients of a pharmacy-based opioid disposal program) on the proportion of patients who disposed or reported intent to dispose of unused opioids. (NCT02814305) Results: We enrolled 79 patients, of whom 72 filled opioid prescriptions. On average, patients received 28 opioid pills and had 15 pills (54%) left over, for a total of 1010 unused pills among the cohort. The behavioral intervention was associated with a 22% absolute increase in the proportion of patients who disposed or reported intent to dispose of unused opioids (Fisher's exact p=0.11).

CONCLUSION

Fifty-four percent of opioids prescribed in this pilot study were not used. The pharmacy-based drug disposal intervention showed a robust effect size but did not achieve statistical significance. Dentists and oral surgeons could potentially reduce opioid diversion by moderately reducing the quantity of opioid analgesics prescribed after surgery.
