North Carolina's Operation Medicine Drop: Results From One of the Nation's Largest Drug Disposal Programs

Patients prefer free drug disposal options delivered by pharmacists at the point of care: Results of a decision tree analysis of a national factorial vignette panel survey

BACKGROUND

Unused opioid medication in the home increases risk of medication diversion, misuse, and unintended harm. The United States Federal Food and Drug Administration is currently considering the implementation of a risk evaluation and mitigation strategy (REMS) program that would require US pharmacists to provide drug disposal products with opioid prescriptions. Still, little is known about consumer preference for drug disposal method. The objective of this study was to identify product and program characteristics associated with consumer preference for at-home drug disposal products.

METHODS

A 2x2x3x3 full-factorial design was employed to text-based vignettes representing opioid analgesic disposal scenarios. Each vignette varied on four characteristics: product cost (free vs paid), ease of use (a mail back envelope, bringing medication to a takeback site, and an at-home drug deactivation pouch), potential environmental impact (incineration), and point of access (pharmacy, community organization, and prescriber). Of the 36 possible vignettes, 12 were removed as they represented a non-realistic combination of vignette characteristics. The remaining 24 were administered to a panel of patients with controlled-substance use in the past six-months. Decision tree modeling and general linear mixed (GLM) models were used sequentially to identify product characteristics associated with patient drug preferences RESULTS: A total of 1,006 participants completed all vignette drug disposal scenarios. Regression tree analysis found that the most important predictor of use was cost followed by ease of access and product design. GLM showed that takeback programs offered at a pharmacy were the most preferred disposal option followed by at-home products (mailed envelope or deactivation system) dispensed with the prescription.

CONCLUSION

Programs that provide disposal resources directly to the patient at no cost with their prescription are likely to optimize willingness to dispose. Findings support the FDA's plan for a REMS program requiring pharmacies to distribute mail-back envelopes to patients when dispensed opioids.

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.

Primary Prevention of Prescription Drug Misuse Among Culturally and Linguistically Diverse Suburban Communities

Comprehensive strategies for prescription drug misuse must reach culturally and linguistically diverse suburban populations to effectively combat the ongoing opioid epidemic. The purpose of this study was to conduct a community needs assessment and inform the development and implementation of culturally appropriate primary prevention strategies for community-based interventions, specifically related to medication disposal practices. Three data collection techniques were utilized: key informant interviews (n = 4), intercept surveys (n = 71), and focus group discussions (n = 8; 61 participants). To accommodate linguistically diverse subpopulations, surveys and focus groups were available in English, Spanish, Arabic, Russian, and Hindi. Participants were overwhelmingly female (survey: 70%/FGD: 84%), ethnic minorities (survey: 61%/FGD: 66%), and, on average, middle-aged [survey: 52 years (SD: 19)/FGD: 54 (15)]. Approximately one in three survey respondents (30%) had heard of drug-take back events, and one in ten (10%) had participated. Non-English speakers were less likely to both perceive a community problem with prescription drugs (β = - .35; p < .001) and be aware of take-back opportunities (β = - .23; p = .038). Focus group participants expressed confusion about appropriate medication disposal methods, identifying potential sources of conflicting information. Recent media coverage and political events have heightened stigma towards non-English speaking and non-native peoples, increasing their fear of law enforcement and other perceived threats. To encourage community engagement in take-back events, we identified multiple ways, such as multilingual materials and marketing campaigns, which may help marginalized suburban subpopulations feel less threatened and more included in prescription drug misuse prevention activities.

Medication disposal practices: Increasing patient and clinician education on safe methods

Recent research suggests that the nation’s water supply is contaminated with trace pharmaceuticals that exert a negative environmental and public health impact. Incorrect medication disposal methods (e.g. flushing medications down the toilet or drain) are a significant factor contributing to the presence of medication compounds in the aquatic environment. In this commentary, we provide a summary of the existing data on pharmaceuticals in the nation’s water as well as the role of improper medication disposal methods on water contamination. We discuss statistics on improper medication disposal practices among patients and clinicians as well as recent advances in proper medication disposal methods as a solution to this problem. Currently, many patients and clinicians are not aware of proper medication disposal practices. We summarize the importance of patient and clinician education in advancing environmental-safe medication disposal methods.
