Patients' intention to consume prescribed and non-prescribed medicines: A study based on the theory of planned behaviour in selected European countries

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.

The self-medication behaviors of residents and the factors related to the consideration of drug efficacy and safety-A cross-sectional study in China

Background: Over-the-counter (OTC) drugs facilitates residents self-medication. However, inappropriate self-medications have become a serious problem in China and even all over the world. Objectives: To make an investigation on the current status of Chinese residents' self-medication behaviors and important considerations, and to explore the factors related to the considerations of drug efficacy and safety. Design: A quantitative, cross-sectional study. Methods: Multi-stage sampling was used to conduct a cross-sectional investigation in China 22 provinces, 5 autonomous regions and 4 municipalities directly under the Central Government. State that an interviewer-administrated questionnaire, was used for data collection. The questionnaire that was used in the investigation included demographic sociological characteristics, health literacy scale-short form (HLS-SF), the 10-item Big Five Inventory (BFI-10), the EuroQol-5D visual analogue scale (EQ-5D VAS), self-medication status and important considerations when self-medicating. Descriptive statistics were performed, and the Chi-square test was used for univariate analysis. Log-binomial regression was used for multivariate analysis on whether residents regard drug efficacy or safety as an important consideration. Results: 9256 respondents were included in the data analysis. The self-medication rate of Chinese adults was as high as 99.1%. Paracetamol and other analgesics were the most common types of OTC medication that respondents purchased, followed by vitamins/minerals. Medical staff recommendations, drug safety and efficacy were the top three important considerations. The residents in the east, central and western regions who consider safety is 63.5%, 61.5%, and 66.8% respectively. The proportion of curative effect was 60.2%, 55.7%, and 61.4% respectively. Log-binomial regression showed that western respondents, retired people, those who mainly used ways including basic medical insurance for employees, commercial medical insurance, free medical treatment to cover their medical cost, respondents with high neuroticism, high health literacy were more likely to consider drug safety as an important factor (p < 0.05). Eastern respondents, employed, main way of medical expenses borne was Out-of-pocket Payment, those with chronic disease were more likely to consider drug efficacy as an important factor (p < 0.05). Female, respondents with high levels of agreeableness, conscientiousness, openness, and self-rated health status were more likely to regard both drug safety and efficacy as important considerations (p < 0.05). Conclusion: Self-medication is practiced by most Chinese adults. Whether Chinese adults take drug efficacy or safety as an important consideration is related to their demographic and sociological characteristics, Big Five personality characteristics, health literacy and self-assessed health status. There is a need to strengthen the management of OTC drugs and public education about self-medication.

Community Attitudes and Habits Toward Over-The-Counter Drugs: Results of a Study Conducted in Thessaloniki, Greece

OBJECTIVES

To determine the frequency of use, sources of information, and selection criteria of Greek residents regarding over-the-counter (OTC) drugs, as well as their opinion about their dispensing in nonpharmacy settings.

METHODS

This was a survey study in which an anonymous cross-sectional questionnaire was used to assess the knowledge, habits, and attitudes about OTC drugs. Data were collected from March 2017 to July 2017 in Thessaloniki, the second largest city in Greece. Logistic regression was used to investigate significant factors that affect the participants' behavior.

RESULTS

A total of 782 participants completed the questionnaire. The population had a mean (SD) age of 46 (17) years and 55.1% were females. About one-third (32.5%) of the participants used nonsteroidal anti-inflammatory drugs more than once per week. OTC drugs acting on the gastrointestinal tract were used to a lower extent (13.2%). The majority (84%) of the respondents consult a healthcare professional about the information on OTC drugs. Furthermore, when not sure about which OTC drug to use, 510 participants (65.6%) valued their physician's advice, whereas 480 participants (60.2%) valued their pharmacist's advice. Most participants (61.2%) were negatively inclined toward the purchase of OTC drugs in nonpharmacy settings, with younger participants being more receptive to out-of-pharmacy OTC drug purchase than older ones (odds ratio 2.20; 95% confidence interval 1.37-3.54).

CONCLUSIONS

Healthcare professionals play an important role in providing people information on their selection of OTC drugs. This could be the main reason why participants prefer to buy OTC drugs from community pharmacies rather than retail shops.

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.

Economic and Behavioral Influencers of Vaccination and Antimicrobial Use

Despite vast improvements in global vaccination coverage during the last decade, there is a growing trend in vaccine hesitancy and/or refusal globally. This has implications for the acceptance and coverage of a potential vaccine against COVID-19. In the United States, the number of children exempt from vaccination for “philosophical belief-based” non-medical reasons increased in 12 of the 18 states that allowed this policy from 2009 to 2017 (1). Meanwhile, the overuse and misuse of antibiotics, especially in young children, have led to increasing rates of drug resistance that threaten our ability to treat infectious diseases. Vaccine hesitancy and antibiotic overuse exist side-by-side in the same population of young children, and it is unclear why one modality (antibiotics) is universally seen as safe and effective, while the other (vaccines) is seen as potentially hazardous by some. In this review, we consider the drivers shaping the use of vaccines and antibiotics in the context of three factors: individual incentives, risk perceptions, and social norms and group dynamics. We illustrate how these factors contribute to the societal and individual costs of vaccine underuse and antimicrobial overuse. Ultimately, we seek to understand these factors that are at the nexus of infectious disease epidemiology and social science to inform policy-making.

Over-the-counter medicines, economic conditions, and citizens most in need in Greece: Is it a challenge for primary care research?

INTRODUCTION

Recent austerity experiences in Greece suggest a plausible link between extensive use of over-the-counter (OTC) medicines and socio-economic peculiarities of life.

COMMENTARY

During the economic crisis in Greece, accessibility to healthcare services has been impacted, particularly for people with low income. However, this fact has not been systematically analyzed in conjunction with an observed increase in use of OTC medicines. Gaining a better understanding of the reasons leading to self-care may help to answer additional questions. Further research is needed to assess the gap between self-care and medically assisted care/treatment by designing pilot monitoring actions and focusing on behaviours related to OTC medicine use. Primary care can offer more collaboration between primary care physicians, community pharmacists, patients, and their families.

IMPLICATIONS

It is crucial to create a multimodal research plan to gain a better understanding of motivational reasons that eventually lead to increasing use of OTC medicines. Efforts should be made to develop data collection techniques that will elicit information from various social groups that focus on changeable behaviours and perceived needs in relation to medicine consumption.

Use of non-HIV medication among people living with HIV and receiving antiretroviral treatment in Côte d'Ivoire, West Africa: A cross-sectional study

Background

In Côte d’Ivoire, people living with HIV (PLHIV) have free access to antiretroviral therapy (ART) and cotrimoxazole. Yet, they may use other medications to treat non-HIV diseases. Scarce data are available regarding the use of non-HIV medications in Africa. This study describes the use of non-HIV medications and identifies the factors associated with their use by PLHIV on ART in Côte d’Ivoire.

Methods

A cross-sectional study was conducted in six HIV clinics in 2016. HIV-1-infected adults receiving ART for at least one year were eligible. A standardized questionnaire was used to collect demographics, HIV characteristics and medication use data. Associated factors were identified using a multivariate adjusted Poisson regression.

Results

A total of 1,458 participants (74% women) were enrolled. The median age was 44 years, and the median duration of ART was 81 months. A total of 696 (48%) participants reported having used at least one non-HIV medication. Among the 1,519 non-HIV medications used, 550 (36%) had not been prescribed and 397 (26%) were from the nervous system class. Individuals who were more likely to report the use of at least one non-HIV medication included those who had been treated in an Abidjan HIV clinic, had a high school education level, had a monthly income between 152 and 304 euros, had a poor perceived health status, had WHO advanced clinical stage, had used traditional medicine products and had not used cotrimoxazole.

Conclusion

Almost half PLHIV on ART reported using non-HIV medication. Further research is needed to assess whether the use of non-HIV medication is appropriate given about a third of those medications are not being prescribed.
