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

Perceptions of disposal options for unused opioid analgesics among people who have been prescribed an opioid analgesic in North Carolina

Background: Medication disposal programs have been promoted as one solution to the opioid crisis, but uptake by community members has been minimal.Objectives: To clarify perceptions of medication disposal options among people who have been prescribed an opioid analgesic in North Carolina to inform interventions that can facilitate the disposal of unused opioids.Methods: In 2022, we conducted focus groups with participants who received an opioid medication in the past year to gain information to develop an intervention related to the disposal of unused opioid medication (12 focus group discussions (FGDs); total N = 37; 30 identified as female, 6 as male, and 1 as another gender). Participants were shown a slide with the Food and Drug Administration's recommended disposal options and asked about their perceptions of each option. Themes were derived using an inductive, thematic, qualitative approach.Results: Seven themes about perceptions of medication disposal programs emerged from the data. Four of the themes reflect potential barriers to medication disposal: failed disposal attempts, lack of sufficient education on proper disposal, unclear meaning of specific disposal language, and concerns about existing disposal options. Three of the themes provide insight on potential facilitators of medication disposal: preference of low-cost disposal options, ease and accessibility among disposal methods, and preferred disposal methods.Conclusion: Patients should be provided clear and consistent guidance from prescribers and dispensing pharmacists on when and how to dispose of unused medications and opportunities to dispose of medications at no cost to the patient.

Association of Opioid Disposal Practices with Parental Education and a Home Opioid Disposal Kit Following Pediatric Ambulatory Surgery

BACKGROUND

The majority of opioid analgesics prescribed for pain after ambulatory pediatric surgery remain unused. Most parents do not dispose of these leftover opioids or dispose of them in an unsafe manner. We aimed to evaluate the association of optimal opioid disposal with a multidisciplinary quality improvement (QI) initiative that proactively educated parents about the importance of optimal opioid disposal practices and provided a home opioid disposal kit before discharge after pediatric ambulatory surgery.

METHODS

Opioid disposal behaviors were assessed during a brief telephone interview pre- (Phase I) and post-implementation (Phase II) after surgery. For each phase, we aimed to contact the parents of 300 pediatric patients ages 0 to 17 years who were prescribed an opioid after an ambulatory surgery. The QI initiative included enhanced education and a home opioid disposal kit including DisposeRX®, a medication disposal packet that renders medications inert within a polymeric gel when mixed with water. Weighted segmented regression models evaluated the association between the QI initiative and outcomes. We considered the association between the QI initiative and outcome significant if the beta coefficient for the change in intercept between the end of Phase I and the beginning of Phase II was significant. Safe opioid disposal and any opioid disposal were evaluated as secondary outcomes.

RESULTS

The analyzed sample contained 161 pediatric patients in Phase I and 190 pediatric patients in Phase II. Phase II (post-QI initiative) cohort compared to Phase I cohort reported higher rates of optimal (58%, n = 111/190 vs 11%, n = 18/161) and safe (66%, n = 125/190 vs 34%, n = 55/161) opioid disposal. Weighted segmented regression analyses demonstrated significant increases in the odds of optimal (odds ratio [OR], 26.5, 95% confidence interval [CI], 4.0-177.0) and safe (OR, 4.4, 95% CI, 1.1-18.4) opioid disposal at the beginning of Phase II compared to the end of Phase I. The trends over time (slopes) within phases were nonsignificant and close to 0. The numbers needed to be exposed to achieve one new disposal event were 2.2 (95% CI, 1.4-3.7]), 3.1 (95% CI, 1.6-7.4), and 4.3 (95% CI, 1.7-13.6) for optimal, safe, and any disposal, respectively.

CONCLUSIONS

A multidisciplinary approach to educating parents on the importance of safe disposal of leftover opioids paired with dispensing a convenient opioid disposal kit was associated with increased odds of optimal opioid disposal.

Development and Evaluation of Messages to Facilitate Secure Storage and Disposal of Prescribed Opioid Medication

BACKGROUND

Secure storage and disposal is a critical strategy to reduce prescription opioid misuse. We sought to develop effective messages to promote secure storage and disposal of unused opioid medications that can be used in interventions designed to reduce diversion of opioid medications for nonmedical use.

METHODS

We used a mixed-method design to develop and evaluate messages. First, we pretested 34 messages in focus group discussions (FGDs; n = 12 FGDs, n = 2-5 participants per FGD; 37 total participants). Then, we tested the 12 most salient messages in an online survey with a nationally representative Qualtrics® panel (n = 1520 participants). A pretest-posttest design was conducted to assess change in beliefs about storage and disposal of opioid medication following message exposure.

RESULTS

All 12 messages favorably influenced participants' perceptions related to concerns and risks of retaining unused opioid medications and the importance of and self-efficacy in securely storing and disposing of unused opioid medications. Storage and disposal messages that included the sentence-"Your prescription can become someone else's addiction."-outperformed other messages in encouraging people to safely store or dispose of opioid medication.

CONCLUSIONS

This study informs the development of a universal text message intervention using multimodal feedback from the target population that the intervention seeks to serve. The next step is to conduct a randomized controlled trial to assess efficacy of the intervention.

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.

Applying blockchain technology in the corporate bond model for default risk assessment under the marketization principle

This work expects to solve the problem that the traditional corporate bond model for default risk assessment has low accuracy and poor data collection and storage robustness. Firstly, this work uses the mature Kealhofer, McQuown, and Vasicek (KMV) model to evaluate the default risk of corporate bonds. Secondly, Blockchain (BC) technology's Information Security (SEC) performance in default risk assessment is studied. Finally, it analyzes the default disposal mechanism of Chinese bond corporates. The Wind database is selected to verify the proposed model. The results show that the proposed BC-based corporate bond model for default risk assessment has a good fitting effect and can meet practical needs. The BC-based data encryption only needs 14.1 ms to obtain a key from an 821-bytes public key. The encryption time and decryption time of the Number Theory Research Unit (NTRU) system are 7.9 ms and 2.9 ms, respectively. Therefore, BC technology shows good performance in data encryption and can improve ISEC. According to the KMV model, corporate bonds have certain default risks. The Distance to Default (DtD) of corporate bonds is 20.8% lower than that of companies. Thus, corporates have higher default risk. Therefore, methods are needed to reduce the default risk and improve the earnings. The finding provides important technical support for effectively reducing the default risk of bond corporates in China and ensuring the healthy development of bond markets.

A systematic assessment of the epidemiologic literature regarding an association between acetaminophen exposure and cancer

Introduced in the 1950s, acetaminophen is one of the most widely used antipyretics and analgesics worldwide. In 1999, the International Agency for Research on Cancer (IARC) reviewed the epidemiologic studies of acetaminophen and the data were judged to be "inadequate" to conclude that it is carcinogenic. In 2019 the California Office of Environmental Health Hazard Assessment initiated a review process on the carcinogenic hazard potential of acetaminophen. To inform this review process, the authors performed a comprehensive literature search and identified 136 epidemiologic studies, which for most cancer types suggest no alteration in risk associated with acetaminophen use. For 3 cancer types, renal cell, liver, and some forms of lymphohematopoietic, some studies suggest an increased risk; however, multiple factors unique to acetaminophen need to be considered to determine if these results are real and clinically meaningful. The objective of this publication is to analyze the results of these epidemiologic studies using a framework that accounts for the inherent challenge of evaluating acetaminophen, including, broad population-wide use in multiple disease states, challenges with exposure measurement, protopathic bias, channeling bias, and recall bias. When evaluated using this framework, the data do not support a causal association between acetaminophen use and cancer.
