Sharing prescription medicines: results of a survey of community pharmacy clients in Auckland, New Zealand

Struggling to afford medicines: a qualitative exploration of the experiences of participants in the FreeMeds study

Introduction Existing research has established that some people struggle with prescription charges. This paper reports on the experiences of a sub-sample of people who participated in the FreeMeds study (a randomised controlled trial of prescription charges) about their problems paying for medicines. Aim The aim of this study was to explore participants' previous experiences with paying for medicines, and the impact of receiving free medicines through the Free Meds study. Method Semi-structured interviews were carried out with 23 people (21 were available for analysis), purposefully selected from the 1061 participants in the FreeMeds trial. Trial participants had to live in an area of high socio-economic deprivation (NZDep 7-10), either take medicines for diabetes and/or take anti-psychotics and/or have chronic obstructive pulmonary disease. Transcripts were analysed thematically. Results Prior to being enrolled in the study, prescription charges were an important issue for many of the participants, who faced multiple health challenges. Some reported having to go without medicines until they could afford them, and many reported having to make hard choices, such as choosing which of their medicines to pick up, or choosing between medicines and other expenses like food. Echoing the quantitative results from the trial, some participants reported previous hospitalisations because of their inability to pay for and hence take, their medicines. Few participants had discussed the affordability of medicines with their doctor. Participants reported that being exempted (through the FreeMeds trial) had reduced their stress and allowed them to afford medicines they would normally have gone without. Discussion The study supports the government's decision to eliminate prescription charges, to remove one barrier to health and wellbeing for people facing significant disadvantages.

Modeling individuals' prescription medicine borrowing behavior

BACKGROUND

Medicine-sharing behavior can be divided into two groups: borrowing medicine from someone else and lending medicine to someone else without consulting a doctor or a pharmacist. There are many reasons for the behavior that leads individuals to share their prescription medicines. However, there is a lack in the literature to investigate individuals' medicine-sharing behavior and related antecedents and outcomes of this behavior.

OBJECTIVE(S)

The main objective of this study is to model individuals' prescription medicine borrowing (PMB) behavior via the structural equation model based on the Theory of Planned Behavior (TPB).

METHODS

A measurement tool was developed according to TPB. Exploratory factor analysis was conducted to determine subfactors of PBM behavior. In the second step, confirmatory factor analysis (CFA) was conducted to confirm whether there is a relationship between the observed variables and their underlying latent constructs. Finally, a structural equation model was conducted to specify the relationships between latent variables. IBM Statistical Package for Social Sciences (IBM SPSS Software) version 22 and LISREL 8.80 were used for data analysis.

RESULTS

Study findings reveal that the participants' attitudes and intentions towards PMB are low, and the rate of exhibiting this behavior is also low. In the proposed prescription medicine borrowing behavior model, the positive effect of attitude towards PMB, perceived behavioral control related PMB, and subjective norm about PMB on intention towards PMB were found statistically significant. Intention towards PMB has been found to have a positive statistically significant effect on PMB behavior.

CONCLUSIONS

Based on the results of this study, it is possible to say that TPB is an appropriate theory for modeling PMB. Thus, this model will shed light on healthcare providers and policy-makers to avoid individuals from the adverse effects of PMB behavior.

Understanding non-recreational prescription medication-sharing behaviours: a systematic review

BACKGROUND

Prescription medication sharing refers to the lending or borrowing of prescription medications where the recipient is someone other than the person for whom the prescription is intended. Sharing prescription medication can cause significant harm. Adverse consequences include an increased risk of side effects, delayed health seeking, and severity of disease. Prevalence estimates vary across different populations and people's reasons for, and perceptions of risks from, sharing are poorly understood.

AIM

To better understand prescription medication-sharing behaviours and practices - specifically, the prevalence, types of medications, reasons, perceived benefits and risks, and factors associated with medication sharing.

DESIGN AND SETTING

This systematic review included primary studies in any setting, focusing on people who engage in medication sharing.

METHOD

Electronic databases were searched from inception of databases to February 2023.

RESULTS

In total, 19 studies were included. Prevalence of lifetime sharing ranged from 13% to 78%. All 19 studies reported that analgesics were the most shared, followed by antibiotics (n = 12) and allergy medication (n = 9). Common reasons for sharing were running out of medication (n = 7), cost (n = 7), and emergency (n = 6). Perceived benefits included resolution of the problem and convenience. Perceived risks included adverse drug reactions and misdiagnosis. Characteristics associated with sharing included age, female sex, having asthma, and unused medicines stored at home.

CONCLUSION

Findings suggest that medication-sharing behaviour is common and involves a range of medicines for a variety of reasons. Data on the prevalence and predictors of prescription medication sharing are inconsistent. A better understanding of non-modifiable and potentially modifiable behavioural factors that contribute to sharing is needed to support development of effective interventions aimed at mitigating unsafe sharing practices.

Caregiver Practices and Knowledge Regarding Leftover Prescription Medications in Homes With Children

OBJECTIVES

The aims of the study were to determine the frequency of and factors associated with leftover or expired prescription medication ("leftover medication") presence in homes with children and to assess caregivers' reported behaviors and knowledge regarding disposal of leftover medications in the home.

METHODS

This study is a planned secondary analysis from a survey of primary caregivers of children aged 1 to 17 years presenting to an emergency department. The survey assessed leftover medications in the home and medication disposal practices, knowledge, and guidance. The survey was developed iteratively and pilot tested. Multivariable logistic regression was used to identify factors associated with leftover medication presence in the home.

RESULTS

We enrolled 550 primary caregivers; 97 of the 538 analyzed (18.0%; 95% confidence interval [CI], 14.8-21.5) reported having leftover medications in their home, most commonly antibiotics and opioids. Of respondents, 217/536 (40.5%) reported not knowing how to properly dispose of medications and only 88/535 (16.4%) reported receiving guidance regarding medication disposal. Most caregivers reported throwing leftover medications in the trash (55.7%) or flushing them down the toilet (38.5%). Caregivers with private insurance for their child were more likely to have leftover medications (adjusted odds ratio [aOR], 1.99; CI, 1.15-3.44), whereas Hispanic caregivers (aOR, 0.24; CI, 0.14-0.42) and those who received guidance on leftover medications (aOR, 0.30; CI, 0.11-0.81) were less likely to have leftover medications in the home.

CONCLUSIONS

Leftover medications are commonly stored in homes with children and most caregivers do not receive guidance on medication disposal. Improved education and targeted interventions are needed to ensure proper medication disposal practices.

Frequency of and Factors Associated With Prescription Medication Sharing Within Families

OBJECTIVES

Limited literature has investigated caregiver sharing of prescription medications with children. Our primary aim was to determine the frequency of and factors associated with prescription medication sharing within families. Our secondary aim was to determine the source and type of medications shared.

METHODS

We conducted a survey of a convenience sample of caregivers of children 1 to 17 years in a pediatric emergency department. The survey was developed through literature review, iterative feedback, and pilot testing on caregivers. We used logistic regression to identify factors associated with any history of medication sharing with a child in the home (primary outcome).

RESULTS

We enrolled 550 primary caregivers; 68 of the 535 analyzed (12.7%; 95% confidence interval [CI], 10.0-15.8) reported prescription medication sharing with their child/children. Of those who shared, 50 (73.5%) shared asthma medications and 14 (20.6%) shared antibiotics. Of the caregivers who shared prescription medications, 70.6% shared a medication for one child with another child, whereas 33.8% of caregivers shared their own or another adult's medication with their child. A child in the home with asthma (adjusted odds ratio [aOR], 3.35; CI, 1.82-6.17), a greater number of children in the household (aOR, 1.29; CI, 1.04-1.60), and a caregiver who previously shared medications with other family members and/or friends (aOR, 4.10; CI, 1.84-9.15) were factors independently associated with medication sharing.

CONCLUSIONS

Prescription medication sharing within families is common and most often involves asthma medications. We identified several factors associated with prescription medication sharing that could be used to target caregivers for preventative interventions.

Differences in the Pattern of Non-Recreational Sharing of Prescription Analgesics among Patients in Rural and Urban Areas

Introduction: This study aimed to analyze differences in sharing of prescription analgesics between rural and urban populations. Methods: We surveyed 1000 participants in outpatient family medicine settings in Croatia. We used a 35-item questionnaire to analyze patients’ characteristics, pain intensity, prescription analgesic sharing behavior, and perception of risks regarding sharing prescription medications. Results: Prescription analgesic sharing was significantly more frequent in the rural (64%) than in the urban population 55% (p = 0.01). Participants from rural areas more commonly asked for verbal or written information than those from urban areas when taking others’ prescription analgesics (p < 0.001) or giving such analgesics (p < 0.001). Participants from rural areas more commonly informed their physician about such behavior compared to those from urban areas (p < 0.01), and they were significantly more often asked about such behavior by their physician (p < 0.01). Perceptions about risks associated with sharing prescription medication were similar between rural and urban populations. Conclusions: There are systematic differences in the frequency of prescription analgesics and associated behaviors between patients in family medicine who live in rural and urban areas. Patients from rural areas were more prone to share prescription analgesics. Future studies should examine reasons for differences in sharing prescription analgesics between rural and urban areas.

'Sharing may not be caring' - Prescription medication sharing among adults in Saudi Arabia

OBJECTIVES

The aim of the current study was to describe prescription medication sharing behaviours (i.e. borrowing and lending) among adults living in Saudi Arabia.

METHODS

This cross-sectional survey was conducted in Saudi Arabia during December 2018. The eligibility criteria were an ability to communicate in Arabic or English and aged ≥18 years. An online survey was distributed to a convenience sample, supplemented by snowballing, by email and social media via an Internet link leading to a web-based survey platform in QuestionPro to assess their medication sharing behaviours. Bivariate and multivariate analyses were used to assess the associations.

KEY FINDINGS

A total of 667 completed the questionnaire. The prevalence of borrowing and lending prescription medication was found to be 14% and 16% in 2018 (past year), respectively. Twenty per cent of participants revealed that they had given a medication prescribed for one child to another child in their care, and 75% reported having leftover prescription medicine at home. The majority (90%) had borrowed or lent on one to three occasions. A wide range of medications were borrowed and lent mainly between immediate family members. Different reasons have been identified for medicine borrowing or lending behaviours.

CONCLUSIONS

Borrowing and lending prescription medications are a common practice in the Saudi population. Further research is warranted into the development of successful approaches or interventions to reduce medication sharing behaviour.

'You don't throw these things out:' an exploration of medicines retention and disposal practices in Australian homes

BACKGROUND

Consumers most commonly discard unwanted medicines in household rubbish or drains, however, there are global concerns over the extent, environmental impact and health risks. When consumers procure or store medicines for future use, this can impact negatively on quality use of medicines and consumer safety. We sought greater insight into the extent of these practices by exploring the volume and types of medicines in Australian homes, and self-reported practices related to medicine accumulation, use and disposal. This qualitative study formed part of a larger project that included a general population survey on household medicine disposal practices.

METHODS

Semi-structured telephone interviews were undertaken with a subset of respondents (n = 166) from the survey. Participants were eligible if they were experienced medicine users, i.e. used five or more prescribed, over the counter, and/or complementary and alternative medicines. Participants were asked to collect and name all medicines in their household; further detail was obtained about medicines used only when required or no longer used, such as expiry dates and quantity remaining. The quantitative data on the number and type of medicines stored at home were analysed descriptively. All interviews were transcribed verbatim and thematically analysed.

RESULTS

A total of 2301 medicines were identified as 1424 medicines not in everyday use (unused, unwanted, expired or when required) in 166 households, and 877 regularly used medicines by 119 participants. Medicines were often stored in multiple locations, particularly kitchens. Although accidental ingestion in children and pets and decreased efficacy were recognised health risks, this did not always translate to appropriate storage, usage or disposal practices. Individual risk-benefit assessments were applied to decisions to retain, use or dispose of medicines, including expired medicines.

CONCLUSIONS

Inappropriate medicine storage, use, and/or disposal practices raises public health concerns, particularly as there is a free returned medicines scheme available, and that this particular participant group were considered experienced medicine users. Healthcare professionals must act to address consumer misconceptions around the quality use of medicines, including medicine retention, storage and disposal. Future research is warranted to explore consumer practices in this context and confirm these findings in a younger, or healthier population.

Prevalence and predictors of medicine saving and future prescription medicine sharing: findings from a New Zealand online survey

OBJECTIVES

To assess the prevalence of and factors predicting future prescription medicine sharing behaviours among adults in New Zealand (NZ). The prevalence and predictors of having leftover medicines at home and the relationship between medicine storing and sharing practices were also explored.

METHODS

An online, self-administered survey of a convenience sample of NZ adults was conducted. Logistic regression analysis was used to examine the association between explanatory and outcome variables.

KEY FINDINGS

Two hundred and thirty three participants took part, who were mostly members of patient support groups across NZ. A high prevalence of leftover medicine storing practices (72.4%), future prescription medicine borrowing (72.8%) and lending (68.7%) behaviours was documented. Over half of the participants (57.1%) had never received advice from healthcare providers about the safe disposal of medicines, and 79.7% reported never having received information about risks of medicine sharing from healthcare providers. In multivariate logistic regression analysis, high income, having asthma and having leftover medicines stored at home were found to be positive predictors of future medicine lending or borrowing intentions. Further, high income was a positive predictor of having leftover medicines stored at home. Conversely, those with hypertension would be less likely to lend or borrow medicines.

CONCLUSIONS

The high prevalence of leftover medicine storing practices and future medicine sharing intentions among adults in NZ suggests it may be beneficial to provide patient and public education about appropriate use of prescribed medicines and safe medicine disposal procedures. Further research is needed to elicit effective strategies to reduce leftover medicines and unsafe medicine sharing practices.

Prevalence of borrowing and sharing prescription medicines and associated socio-demographic factors: findings from COBERS health centres in northern Uganda

BACKGROUND

The use of prescription medications without the involvement of medical professionals is a growing public health concern. Therefore this study was conducted to determine the prevalence of borrowing and sharing prescription medicines and associated socio-demographic factors among community members who had sought health care from COBERS health centres.

METHODS

We conducted analytical cross - sectional study among former patients who sought treatment during the two months period prior to data collection in nine COBERS health centres. We used cluster proportional-to-size sampling method to get the numbers of research participants to be selected for interview from each COBERS site and logistic regression model was used to assess the associations.

RESULTS

The prevalence of borrowing prescription medication was found to be 35.9% (95% CI 33.5-38.2%) and sharing prescription medication was 32.7% (95% CI 30.4-34.9%). The Socio-demographic factors associated with borrowing prescription medicines were: age group ≤19 years (AOR = 2.64, 95%CI 1.47-4.74, p-value = 0.001); age group 20-29 years (AOR = 2.78, 95%CI 1.71-4.50, p-value≤0.001); age group 30-39 years (AOR = 1.90, 95%CI 1.18-3.06, p-value = 0.009); age group 40-49 (AOR = 1.83, 95%CI 1.15-2.92, p-value = 0.011); being a female (AOR = 2.01, 1.58-2.55, p-value< 0.001); being a Pentecostal by faith (AOR = 1.69, 95%CI 1.02-2.81, p-value = 0.042) and being Employed Salary Earner (AOR = 0.44, 95%CI 0.25-0.78, p-value = 0.005). The socio-demographic factors associated with sharing prescription medicines were: age group ≥19 years (AOR = 4.17, 95%CI 2.24-7.76, p-value< 0.001); age group 20-29 years (AOR = 3.91, 95%CI 2.46-6.29, p-value< 0.001); age group 30-39 years (AOR = 2.94, 95%CI 2.05-4.21, p-value< 0.001); age group 40-49 years (AOR = 2.22, 95%CI 1.29-3.82, p-value = 0.004); being female (AOR = 2.50, 95%CI 1.70-3.47, p-value< 0.001); being Pentecostal by faith (AOR = 2.15, 95%CI 1.15-4.03, p-value = 0.017); and being engaged in business (AOR = 1.80, 95%CI 1.16-2.80, p-value = 0.009).

CONCLUSION

A high proportion of study participants had borrowed or shared prescription medicines during the two months prior to our study. It is recommended that stakeholders sensitise the community members on the danger of borrowing and sharing prescription medicines to avert the practice.

Modifiable risk factors for prescription medicine sharing behaviours

BACKGROUND

Prescription medicine sharing has been defined as giving one's own medicine to someone else (lending) or taking someone else's medicine (borrowing). Medicines can be shared for non-medical purposes (recreational sharing or drug abuse) or for their intended therapeutic benefits (non-recreational sharing, e.g. sharing antibiotics to self-treat); the latter is the focus of this research. Limited research evidence is available about modifiable risk factors for non-recreational medicine sharing and addressing this issue was the main aim of this research.

METHODS

An online, cross-sectional survey design was used. The study population comprised a convenience sample of 233 adults, who were primarily recruited through patient support groups across New Zealand. Principal component analysis was used to develop scales assessing attitudes toward medicine lending and borrowing. Logistic regression was used to examine the relationship between explanatory (demographics, medical conditions, and attitudes towards medicine sharing) and outcome (medicine sharing behaviours) variables.

RESULTS

Half of the study participants reported ever borrowing/lending medicines, and approximately a third of participants reported borrowing/lending in the past year. Modifiable risk factors associated with an increased risk of medicine borrowing behaviour were having more difficulty with accessing medicine ('access-related issue'), stronger 'emotional beliefs about borrowing', and greater 'concern about missing doses.' Greater 'concern for the wellbeing of others' and stronger 'beliefs about the benefits and safety of lending' were associated with an increased risk of medicine lending behaviour. Those with a higher 'perceived risk of harm' were less likely to borrow or lend medicines.

CONCLUSIONS

This research expands the current knowledge of medicine sharing by examining underlying behavioural factors which predict sharing behaviours and that can be modified by interventions. This research suggests using multifaceted interventions which consider health status, behavioural, and psychosocial factors, as these appear to contribute most to medicine sharing.

Using the Behaviour Change Wheel to explore potential strategies for minimising harms from non-recreational prescription medicine sharing

INTRODUCTION

Non-recreational sharing of prescribed medicines can have positive outcomes under some circumstances, but can also result in negative health outcomes. This paper describes a theoretically underpinned and systematic approach to exploring potential interventions to reduce harm.

METHODS

Individual, semi-structured, face-to-face interviews were conducted with purposively sampled pharmacists (n = 8), doctors (n = 4), nurses (n = 6) and patients (n = 17) from Auckland, New Zealand. Thematic analysis of suggested interventions was undertaken, and these were linked to relevant intervention functions of the Behaviour Change Wheel (BCW). Analysis of previously defined factors influencing sharing were mapped onto the "Capability, Opportunity, Motivation - Behaviour" (COM-B) model of the BCW.

RESULTS

COM-B analysis of the factors influencing sharing behaviour revealed: (i) 'Capability'-related factors, such as patient misconceptions about the safety of certain medicines, forgetting to refill or to carry around own medicines, and lack of knowledge about safe disposal of leftover/unused medicines; (ii) 'Opportunity'-related factors included lack of access to health facilities, lack of time to see a doctor, linguistic and cultural barriers, lack of information from healthcare providers about risks of sharing, and having leftover/unused medicines, and (iii) 'Motivation'-related factors included altruism, illness denial, embarrassment about seeing a doctor, not carrying around own medicines, habit, and fear of negative health consequences from missing a few doses of medicines. Five intervention functions of the BCW appear to be the most likely candidates for targeting the factors which relate to medicine sharing. These are education, persuasion, enablement, environmental restructuring and restriction.

CONCLUSIONS

A variety of personal and external factors which influence sharing behaviours were identified, and the BCW provided a means by which theoretically underpinned interventions to reduce potential harms from this behaviour could be proposed. The findings can help with the design of approaches to reduce harm associated with non-recreational medicine sharing.

Prescription medicine sharing: exploring patients' beliefs and experiences

Background

Prescription medicine sharing has been defined as the lending of medicines (giving prescription medicines to someone else) or borrowing of medicines (being given and using a medicine prescribed for another person). This qualitative study explored the views of patients, to elicit information regarding factors influencing medicine sharing behaviours, their experiences of the consequences of prescription medicine sharing, and their risk assessment strategies when deciding to share.

Methods

One-on-one, face-to-face, semi-structured interviews were carried out in Auckland, New Zealand between September 2013 and August 2014 with 17 patients, purposively sampled to provide information from different socio-demographic backgrounds. The interviews were audio recorded, transcribed verbatim and analysed using a general inductive approach. The study received ethical approval, and all interviewees provided written informed consent.

Results

Findings were captured within five overarching themes: types of shared medicines; perceived benefits of sharing medicines; negative experiences of sharing; factors influencing sharing behaviours; and risk assessment strategies. Participants reported that sharing helped them to avoid treatment costs and the inconvenience associated with medical visits such as booking appointments. Conversely, unanticipated side effects, allergies, and taking inappropriate medicines were the main adverse consequences of sharing. Altruism, limited access to medicines/health services, sociocultural factors, and having unused prescription medicines were factors influencing sharing behaviours. Participants reported assessing the safety of sharing a medicine primarily based on symptom matching, past illness experiences, and knowledge about the medicines.

Conclusions

This study enriches previous survey findings, by providing insight into patients' reasons for medicines sharing. Healthcare providers should consider asking their patients about any medicines they have shared and their future sharing intentions, in order to use the opportunity for discussing safer sharing practices, without promoting the behaviour. The findings are helpful for informing the development of potential interventions and targeted educational messages about safe medicine use for patients.
