Public's views on making decisions about over-the-counter medication and their attitudes towards evidence of effectiveness: a cross-sectional questionnaire study

Analysis of Actual Fitness Supplement Consumption among Health and Fitness Enthusiasts

With the rising popularity of fitness supplements, understanding the factors driving their consumption behaviors is crucial. This study investigated the actual consumption of fitness supplements utilizing the Theory of Planned Behavior (TPB), Health Belief Model (HBM), and the Theory of Effort Minimization in Physical Activity (TEMPA) frameworks. The TPB provided insights into how attitudes, subjective norms, and perceived behavioral control influence individuals' intentions to consume fitness supplements. Additionally, the HBM sheds light on perceived effectiveness, benefits, barriers, and health motivation related to supplement consumption. Integrating the TEMPA framework further investigated the role of effort minimization in physical activity contexts. Through an online questionnaire, data were collected from a sample of 250 fitness supplement-consuming respondents. SEM analysis revealed significant associations between behavioral intentions and attitudes, perceived behavioral control, health motivation, and controlled precursors. However, it was seen that subjective norms, perceived effectiveness, perceived benefits, and automatic precursors were deemed insignificant. The findings contribute to a comprehensive understanding of the factors shaping actual consumption behaviors, offering valuable implications for marketers, health professionals, and policymakers seeking to promote informed and responsible supplement use among health and fitness enthusiasts.

Public Awareness and Practice Regarding Over-the-Counter Medications: A Cross-Sectional Study in Al-Ahsa, Saudi Arabia

Background Pharmaceuticals classified as over-the-counter (OTC) medications are also known as self-medications, in which drugs are sold directly to customers without a valid prescription. According to the World Health Organization, self-medication refers to taking medication for ailments that one has self-diagnosed. The public viewed OTC medications as safer, more effective, and beneficial, but misuse can lead to other health issues. Therefore, this study aimed to assess awareness and practices regarding OTC medications. Methodology The study employed a cross-sectional design involving the public residing in Al-Ahsa in eastern Saudi Arabia. The study setting was primary health centers (PHCs) in Al-Ahsa. Four PHCs were chosen by the cluster sampling method. One PHC from each of the four health clusters (northern, southern, middle, and eastern) was selected and a total of 326 people were chosen by simple random sampling from those four PHCs. Data were collected through a structured self-administered questionnaire. Descriptive and inferential statistics such as mean, standard deviation, chi-square, and correlation analyses were used to analyze the results. Results  The mean age of the participants was 38.26 ± 9.73 years. The overall mean knowledge score regarding OTC medications was 14.21 (SD = 3.3). About 39 (11.96%) of the participants had adequate knowledge, 184 (56.44%) had moderately adequate knowledge, and 103 (31.6%) had inadequate knowledge about the safety of using OTC medications. The overall mean score of practices was 20.7 ± 4.42. The chi-square test results showed a significant (p < 0.01) association between the level of knowledge and age, occupation, nationality, and marital status. Additionally, a positive linear relationship (r=+.386) was found between knowledge and practices regarding OTC medications. Conclusion In conclusion, many people in the present study had moderate knowledge and good practices regarding OTC medications. To protect the public from harm, there is an urgent need for more concrete regulatory control over OTC drugs and self-medication. So, it is recommended to create awareness about the proper use of OTC medications.

Reasonable access: important characteristics and perceived quality of legal and illegal sources of cannabis for medical purposes in Canada

BACKGROUND

Throughout the past two decades of legal medical cannabis in Canada, individuals have experienced challenges related to accessing legal sources of cannabis for medical purposes. The objective of our study was to examine the sources of cannabis accessed by individuals authorized to use medical cannabis and to identify possible reasons for their use of illegal sources.

METHODS

Individuals who participated in the Cannabis Access Regulations Study (CANARY), a national cross-sectional survey launched in 2014, and indicated they were currently authorized to use cannabis for medical purposes in Canada were included in this study. We assessed differences between participants accessing cannabis from only legal sources versus from illegal sources in relation to sociodemographic characteristics, health-related factors, and characteristics of medical cannabis they considered important. A secondary analysis assessed differences in satisfaction with various dimensions of cannabis products and services provided by legal versus illegal sources.

RESULTS

Half of the 237 study participants accessed cannabis from illegal sources. Individuals accessing cannabis from illegal sources were significantly more likely to value pesticide-free products, access to a variety of strains, ability to select strain and dosage, ability to observe and smell cannabis, availability in a dispensary, and availability in small quantities than did individuals accessing cannabis from only legal sources (all p < 0.05). Additionally, participants gave significantly higher satisfaction scores to illegal sources than to legal sources on service-related dimensions of cannabis access (all p < 0.05).

CONCLUSION

Our findings contribute to an understanding of reasonable access to medical cannabis from a patient perspective and how to assess whether it has been achieved. Characteristics of cannabis products and services valued by patients and appropriate to their needs should be incorporated into legal medical cannabis programs to promote the use of legal medical sources. While pertaining specifically to medical use of cannabis in Canada, the findings of this study may also be instructive for understanding the use of illegal cannabis sources for non-medical purposes in Canada and provide insight for other jurisdictions implementing cannabis regulations for both medical and non-medical purposes.

Consumer Impressions of the Safety and Effectiveness of OTC Medicines

The public generally believes OTC medicines to be helpful for treating minor ailments. From a survey point of view, that position often originates from feedback obtained when these medicines are considered as one broad category. The objective of the study was to assess the properties of 15 categories of agents across three dimensions-effectiveness, safety, and familiarity. Data were gathered via an online non-random survey in one Canadian province, where residents were asked to consider 15 OTC medicine categories in terms of those dimensions. Five hundred and seventy-five completed surveys were obtained out of 3000 sent. On the 10-point effectiveness scale, values ranged from 5.1 (Athlete's foot cream) to 7.3 (headache medicine). For safety, the medicines were closely grouped (6.0 to 7.4). Cough syrups for children were perceived as less safe than those for adults. There was a trend in that, as product familiarity grew, so did impressions of safety and effectiveness. The results support other reports where OTC medicines are described as safe and effective, although safety ratings were not particularly high. Responders considered these medicines to generally be higher in safety than effectiveness.

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.

Health-Related Content of TV and Radio Advertising of Dietary Supplements—Analysis of Legal Aspects after Introduction of Self-Regulation for Advertising of These Products in Poland

Dietary supplements may have beneficial value but, by definition, they have no therapeutic effect. However, their labeling and especially the advertisements in the media, often make ungrounded health claims. The aim of the study was to analyze the content of audio–visual advertisements of dietary supplements for health and legal aspects in the context of the European Law and the 1 January 2020 Polish self-regulation between TV broadcasting companies and supplement manufacturers. Supplement advertisements broadcast across six TV and radio stations from 9–15 March 2020 were analyzed. Most of the analyzed advertisements complied with the legal requirements and included terms such as ‘supports’ or ‘facilitates’ body function, which are less definite in nature. Almost 30% of the advertised supplements made unproven claims on their effectiveness in various health situations, e.g., effective weight loss, thus assuring the addressee about the beneficial effect of dietary supplements in a given health context. Agreement on the rules and regulations governing supplement advertising resulted in a noticeable improvement in advertisement content, which will hopefully raise consumer awareness about the absence of therapeutic properties of dietary supplements.

Effects of Demographic Characteristics and Consumer Behavior in the selection of Retail Pharmacies and Over-the-Counter Medicine

Aim

The study aimed to provide new insights into consumer behaviour by identifying the key demographic factors that influence the choice of pharmacy and over-the-counter (OTC) medicine.

Materials and Methods

A cross-sectional study was conducted in an urban area (Thessaloniki, Greece), surveying a convenience sample of 314 consumers with a structured questionnaire. Data analysis was conducted using the chi-square test, one-way analyses of variance (ANOVAs) and Spearman's rho correlation coefficient.

Results

Respondents with a lower educational level and retired consumers tended to make their purchases in a single pharmacy (p < 0.001). Older participants were more likely to consider the pharmacy staff and additional services to be important factors (p < 0.01). Students were the only group to prefer a formal relationship with the pharmacy staff (p < 0.001). Participants with a lower educational level tended to know exactly what they would buy (p < 0.05), whereas women made more unscheduled purchases of OTCs (p < 0.05). Respondents with a higher income assigned more importance to the product's country of origin (p < 0.05) and manufacturing company (p < 0.01) and less importance to the pharmacist's opinion than those of a lower income (p < 0.05).

Conclusions

The educational level, occupation and age of consumers have a marked effect in their selection of pharmacy, and along with gender and personal income, in their choice of OTC medicine. Our findings yield implications for the management of community pharmacies.

Are evidence-based criteria addressed during counseling on over-the-counter products? An observational study in community pharmacies

OBJECTIVE

We examined whether evidence-based criteria were addressed during counseling on over-the-counter products (OTCs) in community pharmacies.

METHODS

Consultations were observed in 10 community pharmacies. We analyzed communications about OTCs to determine if any information on three evidence-based criteria (outcome variables: scientific evidence such as clinical study results, pharmaceutical staff's experience, and customer's experience) was mentioned. Two groups of communications were compared with Pearson's chi-square and Fisher's exact test, as appropriate: The communications about OTCs recommended by the pharmaceutical staff vs. the communications about OTCs requested by customers.

RESULTS

In 379 observed consultations, 300 OTCs were recommended by staff and 390 OTCs were requested by customers. The least included criterion was scientific evidence (in OTCs recommended by pharmaceutical staff - 1% vs. requested by customers - 0%), followed by pharmaceutical staff's experience (5% vs. 1%). The customer's experience was addressed more frequently (14% vs. 41%). Statistically significant differences between the two groups were found for all criteria (p < 0.05).

CONCLUSION

Evidence-based criteria were rarely addressed during counseling on OTCs.

PRACTICE IMPLICATIONS

Pharmaceutical staff should be encouraged to include the three evidence-based criteria more frequently. Additionally, customers should be encouraged to request such information from the staff in community pharmacies.

Future Pharmacists' Opinions on the Facilitation of Self-Care with Over-the-Counter Products and Whether This Should Remain a Core Role

Background: The aim was to investigate pharmacy students’ views on the role of the pharmacist in facilitating self-care with over-the-counter (OTC) medicines, particularly in light of new roles, and establish personal practice. Methods: Final year pharmacy students at Queen’s University Belfast were invited to participate. Data were collected via a pre-piloted questionnaire, distributed at a compulsory class (only non-identifiable data were requested). Descriptive statistics were performed, and non-parametric tests were employed for inferential statistical analysis (responses by gender). Results: The response rate was 87.6% (78/89); 34.6% (27/78) males and 65.4% (51/78) females. Over a third [34.6% (27/78)] reported using OTC medicines about once a month. All appreciated the importance of an evidence-based approach to optimize patient care. Most [(96.2% (75/78)] deemed OTC consultations should remain a fundamental responsibility of pharmacists and 69.2% (54/78) thought OTC consultations have the potential to be as complex as independent pharmacist prescribing. Females felt more confident recommending OTC emergency contraception than males (p = 0.002 for levonorgestrel and p = 0.011 for ulipristal acetate). Many [61.5% (48/78)] considered more medicines should not be deregulated from prescription-only status. Conclusions: Data from this single institution suggests that enabling self-medication is an important part of practice but there were confidence issues around deregulations.

Communicative and Discursive Perspectives on the Medication Experience

Taking the ‘medication experience’ in the broad sense of what individuals hear and say about their medication, as well as how they experience it, this paper explores diverse research on medication information available to patients and their modes and capacities for interaction, including personal circles, doctors and pharmacists, labeling and promotion, websites, and the patient’s own inner conversations and self-expression. The goal is to illustrate, for nonspecialists in communication, how the actors, messages, mediums, genres, and contextual factors within a standard ethnographic and social semiotic model of discourse and communication are operating, not always effectively or beneficially, to mediate or construct a patient’s medication experience. We also suggest how disparate insights can be integrated through such a model and might generate new research questions.

Over-The-Counter Codeine: Can Community Pharmacy Staff Nudge Customers into Its Safe and Appropriate Use?

The misuse of opioids, including codeine which is sold over-the-counter (OTC) in United Kingdom (UK) community pharmacies, is a growing public health concern. An educational Patient Safety Card was developed and piloted to see if it nudged customers into the safe and appropriate use of OTC codeine. Exploratory analysis was conducted by (i) recording quantitative interactions for people requesting OTC codeine in community pharmacies; and (ii) a web-based pharmacy staff survey. Twenty-four pharmacies submitted data on 3993 interactions using the Patient Safety Card. Staff found the majority of interactions (91.3%) to be very or quite easy. Following an interaction using the card, customers known to pharmacy staff as frequent purchasers of OTC codeine were more likely not to purchase a pain relief medicine compared to customers not known to staff (5.5% of known customers did not purchase any pain relief product versus 1.1% for unknown customers (χ² = 41.73, df = 1, p < 0.001)). These results support both the use of a visual educational intervention to encourage appropriate use of OTC codeine in community pharmacy and the principles behind better self-care.

Generic versus brand-name over-the-counter analgesics: knowledge and attitudes among Swedish pharmacy customers

Background

Due to a liberalisation reform in 2009, the availability of over-the-counter (OTC) analgesics has increased significantly in the Swedish market over the past decade. With the increasing number of generic products available on the market and the possibility of buying OTC drugs from non-pharmacy outlets, a key to safe drug use is that consumers possess the necessary knowledge to differentiate between the different brands and choose the appropriate drug for their ailments. The aim of this study was to investigate Swedish consumers' knowledge of and attitudes towards generic OTC analgesics.

Methods

A sample of 209 Swedish adults (66% women; mean age 43.1 years) who bought OTC analgesics at a community pharmacy in one of the country's three largest cities responded to a structured questionnaire. The questions related to knowledge of active substances, the use and choice of OTC analgesics (generic or original brand), attitudes towards generic OTC analgesics, information received about OTC analgesics and experience with generic substitution of prescription drugs.

Results

Almost one in five reported weekly use of OTC analgesics, and 32% assigned minimum three out of four active substances to the correct brand(s) of OTC analgesics. Among the 50 participants (24%) who assigned all four active substances correctly, it was predominantly women and participants with higher education. Four out of five participants were positive towards the cheaper brands, and 69% reportedly chose cheaper generic brands over more expensive brands. Knowledge about the active substances of different brands was associated with positive attitudes towards generic products.

Conclusion

Swedish pharmacy customers have to a varying extent the knowledge to differentiate between different brands of commonly used OTC analgesics in terms of active substances. There is a predominantly positive attitude towards generic OTC analgesics, although some consider generic drugs to be inferior and stay loyal to the original brands.

Development and validation of prescription drug risk, efficacy, and benefit perception measures in the context of direct-to-consumer prescription drug advertising

PURPOSE

Understanding patient perceptions of prescription drug risks and benefits is an important component of determining risk-benefit tradeoffs and helping patients make informed medication decisions. However, few validated measures exist for capturing such perceptions. The purpose of this study was to develop and validate measures of perception of prescription drug risk, efficacy, and benefit.

METHODS

We conducted a mixed-methods study to develop and validate the measures, including three waves of quantitative testing (item nonresponse, criterion-related validity, and convergent validity). We conducted quantitative testing with a probability-based online consumer panel of U.S. adults (n = 7635), eliminating weaker items after each testing wave.

RESULTS

Upon completion of all testing, we identified 21 validated measures that represent 11 distinct risk/benefit constructs. The final measures demonstrated face validity, convergent validity, criterion-related validity, and scale reliability in both illness and general population samples, among patients with both symptomatic and asymptomatic health conditions, and in response to both television and print direct-to-consumer prescription drug advertisements.

CONCLUSIONS

Our study produced a set of items that researchers and practitioners can use to assess patient perceptions of prescription drug risk, benefit, and efficacy and to ensure greater future comparability between studies.

A pilot study of decision factors influencing over-the-counter medication selection and use by older adults

BACKGROUND AND OBJECTIVES

Despite their availability without prescription, OTC medications pose a risk for significant harm for older adults due to higher likelihood of polypharmacy, drug interactions, and age-related physiological changes. The purpose of this study is to identify the individual decision factors that influence how older adults select and use over-the-counter medications.

METHODS

A pilot study was conducted with 20 community-dwelling older adults. Older adults met the interviewer at a regional mass merchandise store where they were given both pain and insomnia standardized scenarios. Participants described how they would select and then hypothetically use a given medication to treat the problem described in the scenario.

RESULTS

OTC medication selection and reported use were influenced by several person-level decision-making factors including: personal beliefs/knowledge about OTCs, assessment of the ailment, and medical constraints.

CONCLUSION

The findings from this investigation provide direction for interventions to address unsafe OTC medication selection by older adults.

The impact of evidence from clinical trials on counselling for over-the-counter drugs: A national survey of pharmaceutical staff in German pharmacies

WHAT IS KNOWN AND OBJECTIVE

Evidence from clinical trials should form the foundation of healthcare advice. Comparatively little has been investigated about the implementation of evidence in over-the-counter (OTC) counselling in community pharmacies. The objective of this study was to explore the current impact of clinical trials on OTC counselling from the perspective of pharmaceutical staff.

METHODS

Pharmaceutical staff in German community pharmacies were invited to participate in a nationwide cross-sectional survey using SoSci Survey. Within the questionnaire, the following items were queried: (i) attitudes towards influencing factors on OTC drug recommendation, (ii) practical procedure of OTC drug recommendations, (iii) experiences and challenges in handling clinical trials, and (iv) current and desired continuing education on self-medication. Multiple logistic regression was employed to identify predictors for OTC recommendations based on clinical trials in routine.

RESULTS AND DISCUSSION

In total, 1068 participants completed the survey. (i) Clinical trial data were rated as 'very important' for drug recommendations by 33% and as 'rather important' by 50%. (ii) 8% reported that they base their recommendations on clinical trial data 'in almost all consultations', 40% 'in most consultations'. (iii) 69% faced difficulties in including clinical trial data into their counselling. (iv) 7% read original clinical trials at least once a month. Predictors for routine OTC recommendations based on clinical trials were as follows: male gender, university degree, clinical trials considered to be important for recommendations, inclusion of clinical trials in counselling assessed as easy, higher frequency of reading specialized literature per year, increasing number of working pharmacists in the pharmacy, and more casual than regular customers in the pharmacy.

WHAT IS NEW AND CONCLUSION

Most of the pharmaceutical staff recognize the importance of clinical studies for self-medication advice. Based on self-report, however, clinical trial data are not taken routinely into account in practice. Only a minor proportion of staff routinely deal with studies. Therefore, appropriate instruments are required to make knowledge from clinical trials available in community pharmacies.

The role of evidence in consumer choice of non-prescription medicines

Objectives

To identify factors influencing Australian consumer decision-making and attitudes towards non-prescription medicine (NPM) purchases, pharmacy's role in providing these medications and views around sources of evidence for effectiveness of these products.

Methods

Cross-sectional survey of a general population sample of 1731 adults using an Australian online consumer panel stratified by gender, age and location (State/Territory). Beliefs about NPM purchases and evidence of their efficacy were assessed using a 5-point Likert scale (strongly disagree-strongly agree). Non-parametric measures (Ridit analysis and Mann–Whitney U-test) were used to explore associations between responses and previous experience with medicines.

Key findings

The most important factors when purchasing NPMs were effectiveness and safety. However, personal experience was the most common method of determining effectiveness. Most respondents believed buying NPMs in pharmacies gave access to advice, but were less likely to agree that pharmacies were associated with safe and effective treatments. Around half the respondents agreed that it is wrong to sell treatments lacking scientific evidence; many also agreed that it is up to consumers to decide what they want even without scientific evidence. Individuals experiencing an ineffective NPM were less likely to trust scientific evidence of efficacy as the sole source of effectiveness information; regular prescription medicine users often agreed that scientific evidence is needed to support effectiveness.

Conclusions

Consumers have conflicting views regarding the need for scientific evidence and the desire for patient autonomy in NPM purchases. This presents a challenge for pharmacists wishing to maintain professional obligations to provide evidence-based treatments to consumers.

Frequency of nonaspirin NSAID-relevant coexisting medical conditions in the primary-care setting: a retrospective database review

BACKGROUND

Coexisting medical conditions and concomitant medications contribute to treatment challenges primary-care professionals (PCPs) face daily. The current study assessed the extent and distribution of nonaspirin NSAID-relevant coexisting medical conditions of interest (CMCOI) in patients visiting PCPs.

METHODS

This retrospective database review analyzed data from three large health-care claim databases to identify the frequency of nonaspirin NSAID-relevant CMCOI among adults aged ≥18 years with a PCP visit in 2013. Claim databases employed were the Truven Health MarketScan® Commercial Claims and Encounters database, representative of the privately insured (PI) population; Truven Health MarketScan Multi-State Medicaid, representative of the Medicaid population (Medicaid); and Truven MarketScan Medicare Supplemental, representative of the Medicare population with employer-based supplemental Medicare insurance (Medicare-Supplement). Nonaspirin NSAID-relevant CMCOI, asthma, cardiovascular risk factors, gastrointestinal bleeding risk factors, and renal insufficiency were chosen based on US NSAID over-the-counter Drug Facts label warnings. Frequency of CMCOI was determined for those without and with a musculoskeletal diagnosis.

RESULTS

In each database, ≥19% (19.0% PI, 29.9% Medicaid, 33.6% Medicare-Supplement) had a musculoskeletal diagnosis. A greater proportion of individuals with a musculoskeletal diagnosis had one or more CMCOI compared with those without a musculoskeletal diagnosis (61.3% vs 50.4% PI, 78.1% vs 66.8% Medicaid, 87.1% vs 82.3% Medicare-Supplement). The frequency of one or more CMCOI increased with age in each database. Across databases among CMCOI, cardiovascular risk factors were most common, followed by gastrointestinal bleeding risk factors, and proportions were higher among those with a musculoskeletal diagnosis.

CONCLUSION

These data confirm the high frequency of nonaspirin NSAID-relevant CMCOI among patients presenting to PCPs for musculoskeletal diagnosis, as well as among older patients. These analyses reinforce the critical role health-care professionals can play in identifying patients with nonaspirin NSAID-relevant CMCOI, providing those patients with ongoing guidance on appropriate choice and use of over-the-counter analgesics, and educating patients about the impact aging, health status, concomitant conditions, and medicines have on selection of all medicines, including analgesics.

Self-care for common colds: A European multicenter survey on the role of subjective discomfort and knowledge about the self-limited course - The COCO study

Introduction

Common colds are the most frequently encountered disease worldwide and the most frequent reason for self-care. According to the cross-sectional European Common Colds study (COCO), patients use as many as 12 items on average for self-care. Little is known about the influence of discomfort and knowledge on self-care for common colds.

Main objective

To understand the influence of patients’ discomfort during a cold and their knowledge about the self-limited disease course on the use of self-care measures.

Materials and methods

This COCO analysis included 2,204 patients from 22 European primary care sites in 12 countries. Each site surveyed 120 consecutive adults with a 27-item questionnaire asking about patients’ self-care, subjective discomfort during a cold (discomfort: yes/no), and knowledge about the self-limited course (yes/no). Country-specific medians of the number of self-care items served as a cut-off to define high and low self-care use. Four groups were stratified based on discomfort (yes/no) and knowledge (yes/no).

Results

Participants’ mean age was 46.5 years, 61.7% were female; 36.3% lacked knowledge; 70.6% reported discomfort. The group has discomfort/no knowledge exhibited the highest mean item use (13.3), followed by has discomfort/has knowledge (11.9), no discomfort/no knowledge (11.1), and no discomfort/has knowledge (8.8). High use was associated with discomfort (OR 1.8; CI 1.5–2.2), female gender (OR 1.7; 1.4–2.0), chronic pain/arthritis (OR 1.6; 1.2–2.1), more years of education (OR 1.3; 1.1–1.6), age <48 years (OR 1.3; 1.0–1.5), and lack of knowledge (OR 1.2; 1.0–1.4).

Discussion

Counseling on common colds should address patients’ discomfort and soothing measures in addition to providing information on the natural disease course.

Understanding older adults' medication decision making and behavior: A study on over-the-counter (OTC) anticholinergic medications

BACKGROUND

Older adults purchase and use over-the-counter (OTC) medications with potentially significant adverse effects. Some OTC medications, such as those with anticholinergic effects, are relatively contraindicated for use by older adults due to evidence of impaired cognition and other adverse effects.

OBJECTIVE

To inform the design of future OTC medication safety interventions for older adults, this study investigated consumers' decision making and behavior related to OTC medication purchasing and use, with a focus on OTC anticholinergic medications.

METHODS

The study had a cross-sectional design with multiple methods. A total of 84 adults participated in qualitative research interviews (n = 24), in-store shopper observations (n = 39), and laboratory-based simulated OTC shopping tasks (n = 21). Simulated shopping participants also rank-ordered eight factors on their importance for OTC decision making.

RESULTS

Findings revealed that many participants had concerns about medication adverse effects, generally, but were not aware of age-related risk associated with the use of anticholinergic medications. Analyses produced a map of the workflow of OTC-related behavior and decision making as well as related barriers such as difficulty locating medications or comparing them to an alternative. Participants reported effectiveness, adverse effects or health risks, and price as most important to their OTC medication purchase and use decisions. A persona analysis identified two types of consumers: the habit follower, who frequently purchased OTC medications and considered them safe; and the deliberator, who was more likely to weigh their options and consider alternatives to OTC medications.

CONCLUSION

A conceptual model of OTC medication purchase and use is presented. Drawing on study findings and behavioral theories, the model depicts dual processes for OTC medication decision making - habit-based and deliberation-based - as well as the antecedents and consequences of decision making. This model suggests several design directions for consumer-oriented interventions to promote OTC medication safety.

Community pharmacy customer segmentation based on factors influencing their selection of pharmacy and over-the-counter medicines

Background

Within the competitive pharmacy market environment, community pharmacies are required to develop efficient marketing strategies based on contemporary information about consumer behavior in order to attract clients and develop customer loyalty.

Objectives

This study aimed to investigate the consumers' preferences concerning the selection of pharmacy and over-the-counter (OTC) medicines, and to identify customer segments in relation to these preferences.

Methods

A cross-sectional study was conducted between February and March 2016 on a convenient quota sample of 300 participants recruited in the metropolitan area of Thessaloniki, Greece. The main instrument used for data collection was a structured questionnaire with close-ended, multiple choice questions. To identify customer segments, Two-Step cluster analysis was conducted.

Results

Three distinct pharmacy customer clusters emerged. Customers of the largest cluster (49%; 'convenience customers') were mostly younger consumers. They gave moderate to positive ratings to factors affecting the selection of pharmacy and OTCs; convenience, and previous experience and the pharmacist's opinion, received the highest ratings. Customers of the second cluster (35%; 'loyal customers') were mainly retired; most of them reported visiting a single pharmacy. They gave high ratings to all factors that influence pharmacy selection, especially the pharmacy's staff, and factors influencing the purchase of OTCs, particularly previous experience and the pharmacist's opinion. Customers of the smallest cluster (16%; 'convenience and price-sensitive customers') were mainly retired or unemployed with low to moderate education, and low personal income. They gave the lowest ratings to most of the examined factors; convenience among factors influencing pharmacy selection, whereas previous experience, the pharmacist's opinion and product price among those affecting the purchase of OTCs, received the highest ratings.

Conclusions

The community pharmacy market comprised of distinct customer segments that varied in the consumer preferences concerning the selection of pharmacy and OTCs, the evaluation of pharmaceutical services and products, and demographic characteristics.

A population-based study of risk perceptions of paracetamol use among Swedes-with a special focus on young adults

PURPOSE

The purpose of this study was to investigate risk perceptions of paracetamol use, with a special focus on young adults.

METHODS

A web survey was sent to a representative sample (n = 5838) of the Swedish adult population. Altogether, 3120 persons answered the full questionnaire. Risk perceptions of paracetamol use in relation to sex, age, and education were determined using logistic regression.

RESULTS

Most respondents (70.5%) reported use of paracetamol in the 3 months prior to the study; the highest proportion was found among those aged 18 to 25 years (75.8%). Nine in 10 were over-the-counter (OTC) paracetamol users. A total of 14.2% thought paracetamol is completely harmless to use while 54.3% indicated risks associated with use even when following the dosing instructions. One third disagreed that it is less risky to use paracetamol compared with nonsteroidal antiinflammatory drugs. Three-quarters identified liver damage as a potential consequence of exceeding the recommended maximum daily dose. The likelihood of a high-risk perception was higher in women compared with men, and increased with age. No association was found between risk perception and educational status. Participants aged 18 to 25 years had the same ability to identify risks of overdose as did those aged 26 to 65, but expressed more careless attitudes towards use.

CONCLUSIONS

Although the study population purchased paracetamol primarily OTC, they demonstrated basic awareness of paracetamol use including the potential consequences of overdosing. Young adults (18-25 y), who were the most frequent users of OTC paracetamol, perceived less risk associated with use compared with older participants.

Pharmacy students' use and views on over-the-counter (OTC) medicines: a questionnaire study

INTRODUCTION

The role of the pharmacist centers on ensuring the safe and effective use of medicines, including over-the-counter (OTC) medicines. It is important to ascertain pharmacy students׳ use and opinions on OTC medicines, given that they are the pharmacists of the future and that this market continues to expand. This study aimed to investigate Queen׳s University Belfast (QUB) final-year pharmacy students׳ use and views on OTC medicines. Scarce work has been conducted in this area to date.

METHODS

Following ethical approval and a pilot study, all students (n = 155) were invited to participate in a self-completed questionnaire (n = 20 questions), distributed at a mandatory class. Descriptive statistics and non-parametric tests (Chi-squared and Mann-Whitney U test) were used for data analyses.

RESULTS

The response rate was 99.4% (154/155). The majority (153/155) reported using OTC medicines; the key consideration during personal product selection was effectiveness. Most [96.1% (147/153)] were in agreement that safety was the over-riding concern during OTC consultations. While 96.1% (149/155) considered that using an evidence-based approach improved the quality-of-patient care, 68.0% (104/153) would be prepared to sell a product that lacks evidence of effectiveness, provided it would not cause harm.

CONCLUSIONS

The importance of evidence of effectiveness was acknowledged, yet many students in this study were prepared to recommend unproven products. Further strategies are required at QUB to ensure this routine consideration alongside safety in practice.

Consumer preferences for over-the-counter drug retailers in the reregulated Swedish pharmacy market

Following a large regulatory reform in 2009, which ended the state's pharmacy monopoly, non-pharmacy retailers in Sweden today sell certain over-the-counter (OTC) drugs. The aim of this study was to investigate consumer preferences regarding OTC drug retailers and the reasons for choosing a pharmacy versus non-pharmacy retailer. We conducted a web survey aimed at Swedish adults. Out of a stratified sample of 4058 persons, 2594 agreed to take part (48% women; mean age: 50.3 years). Questions related to OTC drug use, retailer choice and factors affecting the participants' preferences for OTC drug retailers. Logistic regression was conducted to analyse OTC drug use and reasons for retailer choice in relation to sex, age and education. Nine in ten participants reported OTC drug use in the 6 months prior to the study. For their last OTC purchase, 76% had gone to a pharmacy, 20% to a grocery shop and 4% to a convenience store, gas station or online. Geographic proximity, opening hours and product range were reported as the most important factors in retailer choice. Counselling by trained staff was important to 57% of participants. The end of the state's pharmacy monopoly and the increase in number of pharmacies seem to have impacted more on Swedish consumers' purchase behaviours compared with the deregulation of OTC drug sales.

Views of pharmacy graduates and pharmacist tutors on evidence-based practice in relation to over-the-counter consultations: a qualitative study

RATIONALE, AIMS AND OBJECTIVES

Health care services offered to the public should be based on the best available evidence. We aimed to explore pharmacy tutors' and trainees' views on the importance of evidence when making decisions about over-the-counter (OTC) medicines and also to investigate whether the tutor influenced the trainee in practice.

METHODS

Following ethical approval and piloting, semi-structured interviews were conducted with pharmacy graduates (trainees) and pharmacist tutors. Transcribed interview data were entered into the NVivo software package (version 10), coded and analysed via thematic analysis.

RESULTS

Twelve trainees (five males, seven females) and 11 tutors (five males, six females) participated. Main themes that emerged were (in)consistency and contradiction, confidence, acculturation, and continuation and perpetuation. Despite having an awareness of the importance and potential benefits, an evidence-based approach did not seem to be routinely or consistently implemented in practice. Confidence in products was largely derived from personal use and patient feedback. A lack of discussion about evidence was justified on the basis of not wanting to lessen patient confidence in requested product(s) or possibly negating the placebo effect. Trainees became acculturated to 'real-life' practice; university teaching and evidence was deemed less relevant than meeting customer expectations. The tutor's actions were mirrored by their trainee resulting in continuation and perpetuation of the same professional attitudes and behaviours.

CONCLUSIONS

Evidence appeared to have limited influence on OTC decision making. The tutor played a key role in the trainee's professional development. More work could be performed to investigate how evidence can be regarded as relevant and something that is consistently implemented in practice.

Use of over-the-counter (OTC) drugs and perceptions of OTC drug safety among German adults

PURPOSE

In Europe, little empirical evidence is available about over-the-counter (OTC) drug consumption and risk perceptions. The objective of this study was to describe consumers' OTC drug use and perceptions of OTC drug safety in Germany.

METHODS

An online survey based on a quota sample with combined strata for age, gender, and education of 300 adult German participants was conducted in June and July 2013. The survey questionnaire covered the participants' OTC and prescription drug use, risk perceptions of OTC and prescription drugs, package leaflet reading habits, and OTC drug off-label use.

RESULTS

Seven day prevalences of OTC drug use were higher in women (52.0%) than in men (40.8%). The risk perception of specific OTC drugs was impacted by the route of administration, the indication, and the drugs' ingredients. Products for dermal application or plant-based products were considered 'rather not risky' by 82.7-96.6 of the participants, depending on the product. Products for oral use or chemically synthesized substances were considered less safe. While 48.0% of consumers reported always reading the package leaflet of OTC drugs, 44.5% reported not reading it if they knew the drug or believed the drug was very safe. People, 60 years and older, reported significantly lower levels of OTC drug off-label use (9.3%) than younger people (22.0%).

CONCLUSIONS

The 7-day prevalence of OTC drug use in Germany is high, especially among women. Consumers generally have balanced perceptions regarding OTC drug safety. Behaviours and knowledge related to OTC drug use should be considered by health care providers and regulators.

Safety concerns in simultaneous use of prescription and 'over-the-counter' medicines- results of patient survey in Estonia

During the last decades, the share of population using prescription (Rx) medicines has considerably increased. With the wider introduction of self-medication and the use of over-the-counter (OTC) medicines, there is a real threat for drug-drug interactions between Rx and OTC medicines neither identified nor overseen by healthcare specialists.

The objectives of this survey were to ascertain how often, and for what conditions OTC and Rx medicines are used simultaneously, and to discuss possible health hazards connected with the concomitant use of these medicines.

This survey was designed as a descriptive, cross-sectional questionnaire-based interview which was conducted amongst pharmacy customers and patients in urban and rural areas of Estonia in between 2010–2012.

In total, 712 respondents participated in the survey. Of those, 50.4% reported concomitant use of Rx and OTC medicines during the survey. The simultaneous use of Rx and OTC medicines increased with age and the number of chronic diseases (both p < 0.001). Of chronic patients, 37.1% used Rx and OTC medicines on a daily basis over a four-week period before the survey, and considering reported chronic diseases and the most widespread OTC medicines, they could encounter drug-drug interactions between Rx medicines (e.g. antihypertensives, anti-inflammatory medicines) and OTC medicines (e.g. paracetamol, NSAID-s, herbal medicines and adsorbents).

The present survey revealed frequent concomitant use of Rx and OTC medicines. Especially vulnerable are chronic and elderly patients. In the future, both patients and healthcare specialists should pay more attention to possible drug-drug interactions of Rx and OTC medicines.

Predictive factors of self-medicated analgesic use in Spanish adults: a cross-sectional national study

Background

Analgesics are among the most commonly consumed drugs by the world populations. Within the broader context of self-medication, pain relief occupies a prominent position. Our study was to ascertain the prevalence of self-medication with analgesics among the Spanish population and to identify predictors of self-medication, including psychological disorders, psychological dysfunction, mental health status, and sociodemographic and health-related variables.

Methods

We used individualized secondary data retrieved from the 2009 European Health Interview Survey (EHIS) for Spain to conduct a nationwide, descriptive, cross-sectional pharmacoepidemiology study on self-medication with analgesics among adults (individuals aged at least 16 years) of both genders living in Spain. A total of 7,606 interviews were analysed. The dichotomous dependent variables chosen were the answers “yes” or “no” to the question In the last 2 weeks have you taken the medicines not prescribed for you by a doctor for joint pain, headache, or low back pain?” Independent variables were sociodemographic, comorbidity, and healthcare resources.

Results

A total of 7,606 individuals reported pain in any of the locations (23.7%). In addition, analgesic consumption was self-prescribed in 23.7% (1,481) of these subjects. Forty percent (40.1%) of patients self-medicated for headache, 15.1% for low back pain, and 6.7% for joint pain. The variables significantly associated with a greater likelihood of self-medication of analgesics, independently of pain location were: age 16–39 years (2.36 < AOR < 3.68), higher educational level (1.80 < AOR <2.21), psychological disorders (1.56 < AOR < 1.98), and excellent/good perception of health status (1.74 < AOR < 2.68). In subjects suffering headache, self-prescription was associated with male gender (AOR 2.13) and absence of other comorbid condition (AOR 4.65).

Conclusions

This pharmacoepidemiology study constitutes an adequate approach to analgesic self-medication use in the Spanish population, based on a representative nationwide sample. Self-prescribed analgesic consumption was higher in young people with higher educational level, higher income, smoker, and with psychological disorders and with a good perception of their health status independently of the location of pain.

Public knowledge and perceptions of connected health

RATIONALE, AIMS AND OBJECTIVES

This study aims to examine the public's knowledge and perceptions of connected health (CH).

METHODS

A structured questionnaire was administered by face-to-face interview to an opportunistic sample of 1003 members of the public in 11 shopping centres across Northern Ireland (NI). Topics included public knowledge of CH, opinions about who should provide CH and views about the use of computers in health care. Multivariable analyses were conducted to assess respondents' willingness to use CH in the future.

RESULTS

Sixty-seven per cent of respondents were female, 31% were less than 30 years old and 22% were over 60 years. Most respondents had never heard of CH (92%). Following a standard definition, the majority felt CH was a good idea (≈90%) and that general practitioners were in the best position to provide CH; however, respondents were equivocal about reductions in health care professionals' workload and had some concerns about the ease of device use. Factors positively influencing willingness to use CH in the future included knowledge of someone who has a chronic disease, residence in NI since birth and less concern about the use of information technology (IT) in health care. Those over 60 years old or who felt threatened by the use of IT to store personal health information were less willing to use CH in the future.

CONCLUSION

Increased public awareness and education about CH is required to alleviate concerns and increase the acceptability of this type of care.

Where to buy OTC medications? A cross-sectional survey investigating consumers' confidence in over-the-counter (OTC) skills and their attitudes towards the availability of OTC painkillers

OBJECTIVE

To examine consumers' confidence in their own, and also in other people's, over-the-counter (OTC) skills and to describe their attitude towards the availability of OTC painkillers. Moreover we examined the association between confidence in OTC skills and attitudes.

DESIGN

Cross-sectional survey. Mixed methods (postal and electronic) self-administered questionnaire.

PARTICIPANTS

Members of the Dutch Health Care Consumer Panel.

MAIN OUTCOME MEASURES

Consumers' confidence in their own, and in other people's, OTC skills was examined. Confidence was measured by three questions regarding obtaining information on, choosing and using OTC medication. Consumers' attitudes towards availability were assessed using six safety profiles, by asking which channel consumers prefer for each profile.

RESULTS

The response rate was 68% (n=972). Consumers feel confident about their own OTC skills (mean 3.74; 95% CI 3.69 to 3.79, on a 5-point Likert scale), but have less confidence in OTC skills of others (mean 2.92; 95% CI 2.88 to 2.96). Consumers are conservative in their attitudes towards the availability of OTC painkillers. Most consumers prefer painkillers to be available exclusively in pharmacies (41-71% per profile indicated pharmacy only). Moreover, there is an association between confidence in OTC skills and attitudes (p=0.005; β=-0.114). Consumers who are more confident about their own OTC skills prefer OTC painkillers to be more generally available.

CONCLUSIONS

Consumers feel confident about their own OTC skills. However, they would prefer painkillers with safety profiles resembling those currently available OTC, to be available as OTC in pharmacies exclusively. Consumers' confidence in the OTC skills of others is more consistent with their attitudes towards availability of OTC painkillers. Until consumers themselves realise that they are also one of the others, they may overestimate their own OTC skills, which may entail health risks.

Over-the-counter analgesic use by urban Aboriginal people in South Australia

Despite recent health gains for Australian Aboriginal people their significantly poorer health status compared with that of non-Aboriginal Australians remains significant. Within the context of high levels of mortality and morbidity, research highlights significant barriers to timely health-care, access and safe use of prescribed and over-the-counter medicines. The risks to Aboriginal people's health due to unsafe medication use are preventable. The purpose of this article is to present the findings from qualitative research focused on Aboriginal people's knowledge, use and experience of over-the-counter analgesics. The study was conducted in the north-western metropolitan area of Adelaide, which has the largest urban Aboriginal population in South Australia. The employment of an Aboriginal Elder as Cultural Advisor enabled engagement with Aboriginal participants. Purposive 'snow ball' sampling was used to recruit participants for four focus groups [n = 30] and one participant opting for a personal semi-structured interview. Participants worked with the researchers to develop the findings and formulate recommendations. The 25 women and 6 men, aged 20-80 years reported various chronic medical conditions. Focus groups/interview elicited accounts of critical issues concerning safe selection and use of over-the-counter analgesics. Serious health risks were evident due to limited knowledge about safe analgesic use and over-reliance on information from family, friends and advertising. Extremely poor access was reported by participants to culturally and linguistically appropriate information, education and advice from a range of doctors and other health professionals including Aboriginal health workers.

'I can't be an addict. I am.' Over-the-counter medicine abuse: a qualitative study

OBJECTIVES

Over-the-counter (OTC) pharmacy medicines are considered relatively safe in contrast to prescribed and illicit substances, but their abuse and addiction potential is increasingly recognised. Those affected represent a hard to reach group, with little known about their experiences. Study objectives were to describe the experiences and views of those self-reporting OTC medicine abuse, and why medicines were taken, how they were obtained and associated treatment and support sought.

DESIGN

Qualitative study using in-depth mainly telephone interviews.

PARTICIPANTS

A purposive sample of 25 adults, aged 20-60s, 13 women.

SETTING

UK, via two internet support groups.

RESULTS

Individuals considered themselves 'addicted', but socially and economically active and different from illicit substance misusers. They blamed themselves for losing control over their medicine use, which usually began for genuine medical reasons and not experimentation and was often linked to the cessation of, or ongoing, medical prescribing. Codeine, in compound analgesics, was the main medicine implicated with three distinct dose ranges emerging with decongestant and sedative antihistamine abuse also being reported. Subsequent use was for the 'buzz' or similar effects of the opiate, which was obtained unproblematically by having lists of pharmacies to visit and occasionally using internet suppliers. Perceived withdrawal symptoms were described for all three dose ranges, and work and health problems were reported with higher doses. Mixed views about different treatment and support options emerged with standard drug treatment services being considered inappropriate for OTC medicines and concerns that this 'hidden addiction' was recorded in medical notes. Most supported the continued availability of OTC medicines with appropriate addiction warnings.

CONCLUSIONS

Greater awareness of the addiction potential of OTC medicines is needed for the public, pharmacists and medical prescribers, along with appropriate communication about, and reviews of, treatment and support options, for this distinct group.

Price, familiarity, and availability determine the choice of drug - a population-based survey five years after generic substitution was introduced in Finland

Background

Mandatory generic substitution (GS) was introduced in Finland at the beginning of April 2003. However, individual patients or physicians may forbid the substitution. GS was a significant change for Finnish medicine users. It was thought it would confuse people when the names, colors, packages, etc., changed. The purpose of this study was to explore what medicine-related factors influence people's choice of prescription drugs five years after generic substitution was introduced in Finland.

Methods

A population survey was carried out during the autumn of 2008. A random sample was drawn from five mainland counties. A questionnaire was mailed to 3000 people at least 18 years old and living in Finland. The questionnaire consisted of both structured and open-ended questions. Factors that influenced the subjects' choice of medicines were asked with a structured question containing 11 propositions. Descriptive statistical analyses were performed.

Results

In total, 1844 questionnaires were returned (response rate, 62%). The percentage of female respondents was 55%. Price, availability, and familiarity were the three most important factors that influenced the choice of medicines. For the people who had refused GS, the familiarity of the medicine was the most important factor. For the subjects who had allowed GS and for those who had both refused and allowed GS, price was the most important factor.

Conclusions

The present study shows that price, familiarity, and availability were important factors in the choice of prescription medicines. The external characteristics of the medicines, for instance the color and shape of the tablet/capsule or the appearance of the package, were not significant characteristics for people.
