Understanding the Factors Influencing Older Adults' Decision-Making about Their Use of Over-The-Counter Medications-A Scenario-Based Approach

Adapting a community pharmacy intervention to improve medication safety

BACKGROUND

Community pharmacies are an ideal location to address challenges of over-the-counter medication safety, yet many successful interventions are only tested in a few pharmacies without expansion, creating unrealized opportunities to improve patient care on a larger scale. Scaling up to numerous pharmacies can be challenging because each community pharmacy has unique needs and layouts and requires individualized adaptation.

OBJECTIVES

This paper reports techniques for (a) adapting a community pharmacy intervention to fit the unique physical layout and patient needs of health system pharmacy sites without increasing staff workload, (b) identifying strategies to gather feedback on adaptations from stakeholders, and (c) developing materials to share with pharmacy champions for them to independently implement and sustain the intervention in their organization.

PRACTICE DESCRIPTION

The study team collaborated with Aurora Pharmacy, Inc to develop an intervention designed to increase awareness of safe over-the-counter medication use for older adults.

PRACTICE INNOVATION

Senior Safe, a community pharmacy-based intervention, was designed, implemented, and tested using the Exploration, Preparation, Implementation, and Sustainment implementation framework.

EVALUATION METHODS

Senior Safe was adapted through pilot testing and a randomized control trial. Feedback was collected from key stakeholders, including pharmacy staff, older adults, and a research advisory group.

RESULTS

A finalized version of Senior Safe, as well as an implementation package, was provided to Aurora Pharmacy to integrate into all 63 sites.

CONCLUSION

This multiphase study illustrated that refining an intervention is possible and welcomed by pharmacy staff, but it requires time, resources, and funds to create an impactful, sustainable community pharmacy intervention.

Consumer perceptions of the OTC Coach: A clinical decision support system aimed at improving the safe use of over-the-counter medications

BACKGROUND

There are more than 300,000 over-the-counter (OTC) medications on the market making it challenging for consumers to select safe and effective products to treat their minor ailments.

OBJECTIVE

We sought to identify consumer perceptions about the use of a clinical decision support system, OTC Coach, to help them make informed decisions about OTC medications.

METHODS

We developed a prototype of the OTC Coach that focused on treating fever in adults. We recruited community members who were 18 years and older via our institutional research website. Participants completed a 30- to 45-minute video interview in which they initially discussed their perceptions and experiences of using OTC medications. We subsequently shared the OTC Coach prototype and sought feedback related to the content and format of the tool. We asked participants to rate their likelihood of using the tool to treat a new symptom (10-point Likert scale, 1 = not at all to 10 = extremely likely) and conducted a qualitative and quantitative analysis of these findings.

RESULTS

Among 20 participants, 11 (55%) were female, 10 (50%) were white, and the mean age was 47.9 years (range 18-81 years). Participants reported that the tool was easy to understand. The questions reported as being extremely important by most participants were allergies (n = 17, 85%), increased risk of bleeding (n = 15, 75%), temperature (n = 12, 60%), and duration of symptoms (n = 12, 60%). Three-fourths of participants (n = 15) selected a score of 7 or higher when asked about their likelihood of using this tool for a new symptom. Concerns that were raised included ensuring that the tool accounted for their personal health history, data storage, and accessibility.

CONCLUSION

Consumers were interested in using an electronic tool to determine if their symptoms can be self-treated and, if so, which medications are appropriate.

Access to non-prescription medicines via vending machines: key considerations to help transfer the self-care concept to the next generation while managing safety risks

Objectives

Non-prescription vending machines are automated self-service systems that are increasingly used to dispense these medicines. Whilst regulatory health academics have devoted considerable attention to non-pharmacy medication outlets in Gulf Cooperation Council countries and others, the public health literature on these vending machines remains lacking. Whilst non-prescription vending machines undoubtedly provide a number of benefits, they are not without their risks, which include polypharmacy and medication interactions.

Methods

The purpose of this article is to provide a framework for further investigation of the function, advantages, and practical constraints of non-prescription vending machines.

Key findings

Overall, more research is required to determine the optimal balance between achieving the benefits of non-prescription vending machines whilst avoiding unnecessary constraints on regulatory bodies and vending machine providers but minimizing patient harm.

Conclusions

Further studies are also required to assess the consequences of these policy experiments. Specifically, there is a need to better understand the extent to which vending machines can provide beneficial and reasonable access to non-prescription medicines to enhance the quality of life of the population especially during pandemics.

Effectiveness and sustainment of a tailored over-the-counter medication safety intervention in community pharmacies: A randomized controlled trial

INTRODUCTION

The Senior Section is a continuation of a previous intervention that aims to address a gap in medication safety, specifically related to older adult selection and use of over-the-counter medications. The purpose of this paper is to describe the protocol of this study.

METHODS

This study will occur in three phases: an adaptation phase, an effectiveness phase using a randomized controlled trial, and a sustainment phase. This study will take place in conjunction with administrative leadership and pharmacy sites of a regional Midwest integrated health system. Eye tracking technology will inform the adaptation of the intervention and demonstrate effectiveness in the randomized controlled trial. Following the randomized controlled trial, the health system will implement the intervention without research team support. Fidelity and long-term effectiveness outcomes will be collected to demonstrate sustainment.

DISCUSSION

The potential implications of this study are a complete and sustained redesign of the pharmacy setting to include educational and directional materials on medication safety, leading to a decrease in over-the-counter medication misuse in older adults. This project could provide a road map for pharmacy organizations to tailor and adopt the Senior Section, to ultimately reduce inappropriate over-the-counter medication use in older adults.

Self-Efficacy, Social Activity, and Spirituality in the Care of Elderly Patients with Polypharmacy in Germany-A Multicentric Cross-Sectional Study within the HoPES3 Trial

About one third of Europe’s elderly population takes ≥5 drugs. Polypharmacy increases their risk of adverse drug reactions. To ensure drug safety, innovative approaches are needed. The aim of this cross-sectional study was to explore the relationship between psychosocial factors and medication-related beliefs and behaviors. Medication lists of 297 patients were recorded according to the ATC classification. Correlations between the dependent variables, Medication Adherence (MARS) and Beliefs about Medicines (BMQ), and independent variables, General Self-Efficacy (GSE), self-efficacy for managing chronic diseases (SES6G), spiritual needs (SpNQ), patient activity (PAM), loneliness (DJG), and social networks (LSNS), were measured. Patients with higher self-efficacy (OR: 1.113; 95% CI [1.056–1.174]; p < 0.001) or self-confidence in managing their chronic condition (OR: 1.188; 95% CI [1.048–1.346]; p < 0.007) also showed higher adherence. Lonely patients (OR: 0.420; 95% CI [0.267–0.660]; p < 0.001) and those with a need for inner peace (OR: 0.613; 95% CI [0.444–0.846], p = 0.003) were more likely nonadherent. Stronger positive beliefs about medications’ usefulness weakly correlated with higher scores on the SES6G (ρ = 0.178, p = 0.003) and GSES scale (ρ = 0.121, p = 0.042), patient activity (ρ = 0.155, p = 0.010) and functioning social networks scale (ρ = 0.159, p = 0.008). A weak positive correlation was found between loneliness and the belief that drugs were harmful (ρ = 0.194, p = 0.001). Furthermore, interesting correlations were detected regarding the number of medications and overuse beliefs. Psychosocial factors, such as self-efficacy, loneliness, and spiritual needs and medication-related beliefs and behaviors seem to interrelate. Addressing these factors may improve medication management and drug safety.

Consumption of over-the-Counter Drugs: Prevalence and Type of Drugs

Recently, there has been an increase in the use of over-the-counter (OTC) drugs. The consumption of these medicines can be unsafe, as incorrect self-diagnosis or the ingestion of inappropriate doses can lead to side effects and the occurrence of adverse reactions and drug–drug interactions. A cross-sectional descriptive observational study was carried out, targeting the entire Spanish population by using an online questionnaire. The results showed that 78.9% of the subjects had previously taken or were currently taking OTC drugs. This consumption decreased as the age of the subjects increased, with a prevalence of 36.4% of subjects aged ≥ 71 taking OTC drugs. Analgesics were the most consumed OTC drugs (49.1%) especially in women, youngsters with non-formal educational qualifications, and individuals of a low–medium socioeconomic level residing in urban areas. Measures should be implemented to optimize the safe use of OTC drugs in order to avoid the occurrence of secondary events associated with the lack of knowledge related to their the usage.

Impact of a pilot community pharmacy system redesign on reducing over-the-counter medication misuse in older adults

BACKGROUND

No interventions have attempted to decrease misuse of over-the-counter (OTC) medications for adults aged 65 years or older (older adults) by addressing system barriers. An innovative structural pharmacy redesign (the Senior Section) was conceptualized to increase awareness of higher-risk OTC medications. The Senior Section contains a curated selection of OTC medications and is close to the prescription department to facilitate pharmacy staff-patient engagement to reduce misuse.

OBJECTIVE

This pilot study examined the Senior Section's effectiveness at influencing OTC medication misuse in older adults.

METHODS

A pretest-post-test nonequivalent groups design was used to recruit 87 older adults from 3 pharmacies. Using a hypothetical scenario, the participants selected an OTC medication that was compared with their medication list and health conditions, and their reported use was compared with the product labeling. Misuse outcomes comprised drug-drug, drug-disease, drug-age, and drug-label, with 5 subtypes. Patient characteristics were compiled into a propensity score matching logistic regression model to estimate their effects on the Senior Section's association with misuse at pre- or postimplementation.

RESULTS

Patient characteristics were uniform between pre- and postimplementation, and, once entered into a propensity score matching model, drug-label misuse (exceeds daily dosage) statistically significantly lessened over time (z = -2.42, P = 0.015). In addition, the Senior Section reduced drug-label misuse (exceeds single dosage) for both the raw score model (z = -6.38, P = 0.011) and the model in which the patient characteristics propensity score was added (z = -5.82, P = 0.011). Despite these limited statistical effects, misuse was found to decrease after implementation for 7 of 11 comparisons.

CONCLUSION

These nascent outcomes begin providing an evidence base to support a well-conceived, pharmacy-based OTC medication-aisle redesign for reducing older adult OTC medication misuse. The Senior Section, when broadly implemented, creates permanent structures and processes to assist older adults to access risk information when selecting safer OTC medications.

Using a scenario-based hybrid approach to understand participant health behavior

BACKGROUND

Qualitative and mixed methods approaches are commonly used to understand participants' interactions with real-world settings and can help health services researchers to obtain realistic details about patients' health behaviors. However, interviews do not easily capture data about how patients perform health-related behaviors that are not part of their daily routine. A scenario-based approach is one method that can be used prospectively to explore how patients make decisions about their health-related behaviors. This approach is comprised of a set of small tailored probable circumstances with equally plausible situations, and are presented as narrative descriptions. To understand how older adults, a group at high-risk for OTC misuse, select over-the-counter (OTC) medication qualitative methods can be used.

OBJECTIVES

This study describes a scenario-based hybrid approach that included a simulation exercise and a situational interview to understand how older adults first select and then take OTC medication.

METHODS

The scenario-based hybrid approach consisted of 1) a simulation exercise to emulate participants' real-world experiences as they selected a medication in a store, followed by 2) a situational interview to capture how participants intended to take the medication they selected. Video recordings captured interview data as well as participants' body language, navigation patterns, and other nuanced data that would not have been captured in audio recordings.

RESULTS/CONCLUSION

The scenario-based hybrid approach not only yielded detailed information about behavior, but also allowed investigators to discern participants' decision-making, influences, and the rationales they use when selecting and taking OTC medications. Studies aiming to capture participants' behavior in naturalistic situations can use these techniques to draw inferences from direct and indirect visual references that may not be captured otherwise. In this study, the goal was to understand how older adult participants select and take OTC medications. This approach allowed the research team to expediently recreate situations in which participants would purchase an OTC medication, a task that may not occur frequently and thus may not be amenable to participant observation or accurately recalled using retrospective interviewing.
