Over-The-Counter (OTC) Drug Consumption among Adults Living in Germany: Results from the German Health Interview and Examination Survey for Adults 2008⁻2011 (DEGS1)

Self-medication among pregnant women in comparison to the general population: a scoping review of the main characteristics

Objective

An in-depth evaluation of the published evidence is needed on self-medication, specifically the evidence focusing on vulnerable groups, such as pregnant women. This scoping review aims to provide an overview of the differences in self-medication prevalence and study characteristics among different groups, while identifying gaps in the literature.

Methods

A literature search was performed in PubMed and Web of Science, including articles published in the last 10 years for the pregnant women group (PWG) and the general population group (GPG). Data on study design, self-medication prevalence, medications used, and other variables were collected, tabulated, and summarized.

Results

From 2888 screened articles, 75 were considered including 108,559 individuals. The self-medication (SM) in the PWG ranged from 2.6 to 72.4% and most studies had an SM prevalence between 21 and 50% and in the GPG, 32 from 50 studies had a SM prevalence higher than 50%. The reviewed studies varied considerably in methodology, requiring careful interpretation. While most of the studies assessed self-medication during the entire pregnancy, self-medication definition was often inconsistent between studies. Acetaminophen was the most used medication and headache was the most frequent symptom leading to self-medication initiation in the PWG.

Conclusions

Self-medication among pregnant women showed a lower prevalence when compared to the general population. The medications used and symptoms reported were similar between groups. However, methodological differences must be carefully considered. Pregnant women should carefully follow their physicians' advice before initiating self-medication to avoid preventable maternal and fetal adverse effects.

Attitudes, attributions, and usage patterns of primary care patients with regard to over-the-counter drugs-a survey in Germany

Studies show that over-the-counter drugs are widely used by consumers. Moreover, there is a huge selection available and they are prominently featured in advertising. To date, there exist only a few studies that shed light on the attitudes, attributions, and usage patterns of patients with regard to use of over-the-counter drugs. An anonymized explorative waiting room survey was conducted among 900 patients in 60 GP practices in the German states of North Rhine-Westphalia, Hesse, and Rhineland-Palatinate. As well as the descriptive analysis, a t test was applied to independent random samples, in order to identify significant differences between two groups. 65% of respondents reported using over-the-counter drugs frequently or occasionally. With regard to effects, risks, and side effects, 54% state that they usually take advice from their GP and/or pharmacist before purchasing or taking over-the-counter preparations. For 56%, the package information leaflet is a frequent source of information about the over-the-counter drugs used. The respondents consider over-the-counter preparations to be particularly suitable for (preventive) treatment of colds, flu symptoms, and pain management. The widespread perception of over-the-counter drugs as simple to use (62%), low-dose (69%), and low-efficacy (73%) products does not always correspond to the actual capabilities and risks of over-the-counter self-medication. Given the easy availability of over-the-counter drugs and their strong presence in advertising, it is important that patients have a realistic idea of the capabilities and risks of over-the-counter products. In addition to the advice provided by pharmacists, the trusting, long-standing support provided by GPs and their ongoing information and advice services play a central role in this. It would be advisable to give more attention to this public health concern and to promote initiatives to make patients more aware of the risks regarding consumption of drugs without medical consultation.

Self-care and self-medication as central components of healthcare in Germany - on the way to evidence-based pharmacy

In Germany, self-care is, above all interpreted as the prevention and treatment of minor injuries and illnesses by the patients themselves - that is, without a physician's prescription or medical advice. Maintaining one's health in the sense of a preventive approach through non-medicinal measures also plays an important role. Self-medication in this context is the treatment with approved over-the-counter-(OTC)-medications. In addition, other OTC-products such as dietary supplements as well as complementary and alternative medicines including homeopathic medications are frequently requested options by pharmacy customers. OTC-medications are central components of the German healthcare system, with expert advice from pharmacists in community pharmacies (CP) enabling safe and effective treatment. Additionally, screening for appropriate self-medication by pharmacists ensures that serious illnesses receive timely medical attention. In addition to prescribed medication, self-medication is an important part of the CP business in Germany. In contrast to prescription products, the price of OTC-products is not regulated. As a consequence, the price of OTC-products (including also pharmacy-only drugs) is influenced by competition among CPs and mail-order pharmacies, respectively. The sales of OTC-products for self-medication outside pharmacies, e.g. in drugstores and supermarkets, is restricted to a limited number of specific products. Evidence-based counseling in CPs, while generally advocated still remains a challenge. The evidence for the usage of OTC-products from clinical studies is not yet optimally integrated into everyday pharmacy practice. Information tools such as EVInews offering regular newsletters and a database have been developed to reduce the evidence-to-practice gap and to improve the overall counseling quality. Furthermore, the switching of drugs from prescription-only to pharmacy-only status also challenge CPs to provide adequate and updated guidance.

Household Pharmaceutical Waste Disposal as a Global Problem-A Review

The negative effect of the pharmaceuticals presence (persistence?) in various components of the environment is a global problem today. These compounds are released into the environment as a result of, inter alia, their use and improper disposal. Therefore, it is important to reduce excessive drug consumption and to develop a system for the collection of unused/expired pharmaceuticals. The effectiveness of actions in this area is inextricably linked with the need to educate society on how to deal properly with unwanted medications. The aim of the study was to show that the inappropriate handling of unused/expired drugs by society is an important problem in waste management systems, and it impacts the state of the environment. Forty-eight scientific articles published between 2012 and 2021 were taken into account that discussed the systems in various countries for the collection of unused/expired pharmaceuticals. This literature review shows that the main method of disposing of unused/expired medications, according to respondents from different countries, is either by disposing of them in household waste or flushing them into the sewage system. This is also the case in countries with systems or programs for the return of redundant drugs, which indicates that these systems are not sufficiently effective. This may be influenced by many factors, including the lack or ineffective education of the society.

Physical Activity is Associated with Less Analgesic Use in Women Reporting Headache-A Cross-Sectional Study of the German Migraine and Headache Society (DMKG)

INTRODUCTION

The aim of this analysis is to determine whether regular physical activity is associated with less analgesic use in men and women suffering from headache disorders based on population-based cross-sectional data.

METHODS

We used data from a random general population sample in Germany that comprised 2477 participants aged ≥ 14 years. A standardized questionnaire addressing headache and headache treatment was filled in during the face-to-face survey.

RESULTS

Thirty-nine percent of the participants reported headache. Of these, 37.5% of men and 33.6% of women were physically active. Of the participants with headache, 43.3% reported taking analgesics on < 2 days a month, 40.7% on 2-5 days a month, 10.1% on 6-10 days a month, and 5.9% on > 10 days a month. Frequent headache, severe impact of headache on daily life, and depressive symptoms were associated with higher analgesic use in both men and women. For women, physical inactivity was associated with the frequency of analgesic use adjusted for sociodemographic and headache-related variables. For men, results did not suggest any association between physical inactivity and frequency of analgesic use.

CONCLUSIONS

There are both sex-unspecific and sex-specific factors associated with analgesic use among men and women with headache. In women with increased analgesic use, promoting physical activity may reduce analgesic use. For men, education about the therapeutic effects of physical activity for headaches is an important resource.

Knowledge, Attitudes, and Families Practices in Selecting, Obtaining, Using, Storing, and Disposing of Medicines on Self-Medication Behavior in Indonesia

BACKGROUND: The irrational use of medicine in the family is a serious problem. Advances in education, economy, availability of medicines, regulations, and technology have encouraged people to self-medicate in overcoming their illness. Self-medication behavior is not only carried out by adults but also by the elderly, students, and even children. Self-medication can provide positive health benefits if done correctly starting from selecting, obtaining, using, storing, and disposing medicines. On the other hand, if self-medication measures are carried out inappropriately, they can lead to various drug-related risks. AIM: Therefore, this study aimed to describe the knowledge, attitudes, and families practice in selecting, obtaining, using, storing, and disposing medicine and to identify the factors influence of this construct. METHOD: The study was conducted using an analytical method with a cross-sectional approach using a questionnaire for families in Padang Pariaman Regency, West Sumatera, Indonesia, namely, in 2x11 Enam Lingkung and Sungai Garingging Districts. The total sample size obtained was 500 families. Bivariate analysis was determined using Chi-squared test and multivariate analysis was determined using linear logistic regression. RESULTS: Data from current study found that the percentage of the average score of family knowledge of selecting, obtaining, using, storing, and disposing medicines was in a low category (57.53%), family attitudes were in the negative category (59.38%) and family actions were in the negative category (55.27%). The results of multivariate analysis using linear logistic regression showed that the sub-variables that influenced the knowledge, attitudes, and actions of families about medicines were pharmacists/doctors as the main source of information about drugs (p = 0.006), education in the category of secondary education (p = 0.002) and mothers as family members who had a major role in managing medicines (p = 0.000). CONCLUSION: The results show that knowledge, attitudes, and practice of families about medicines are still low and very limited. Factors that influence knowledge, attitudes, and practice of families selecting, obtaining, using, storing, and disposing medicine are pharmacists/doctors as the main source of information about medicine, education, and mothers as family members who have a major role in managing medicines. The lack of knowledge, attitudes, and practice related to medicines and the important role of the family is the reason for the very importance of family-based medicines education.

Wrong administration route of medications in the domestic setting: a review of an underestimated public health topic

Introduction: Since medication errors related to incorrect administration routes are less common than other errors, they are rarely considered when assessing patient mistakes. The present review was performed to search for papers assessing incorrect route medication errors made by adult patients with the aim of providing an overview of this phenomenon.Areas covered: PubMed, Scopus, and EMBASE were searched up to October 2019 using free text and MeSH terms, returning 7609 results. Papers were considered eligible if they considered incorrect administration route errors by adult patients in domestic settings. Eleven papers were included, primarily from National Poison Centers (NPCs) or similar institutions from USA or Europe (observation period: 1985-2014). The data showed how an incorrect route of self-administration is a concern for patient safety and should be considered when evaluating medication errors. Moreover, one of the main observations that the results highlighted was the difficulty of obtaining clear and precise data regarding self-administration.Expert opinion: NPC reports are a reliable but not exhaustive tool due to high underreporting; reports should provide additional information or insights into these issues. Additionally, improvements in drug packaging and labeling, proper plain language instruction and patient education could reduce the frequency of such errors.

What is the attitude towards and the current practice of information exchange during self-medication counselling in German community pharmacies? An assessment through self-report and non-participant observation

Background

Guidelines encourage relevant information exchange between pharmaceutical staff and patients during self-medication consultation. Thereby, assessing the patient’s situation and providing information is crucial for patient safety. So far, limited studies have investigated this information exchange, particularly in Germany. We aimed to assess the attitude towards and the current practice of guideline-recommended information exchange in German community pharmacies.

Methods

In total, twelve guideline-recommended parameters were predefined for gathering patient-related information and for the provision of information. These information exchange parameters were evaluated in two parts: Firstly, in a self-report of pharmaceutical staff via an online questionnaire to assess the reported importance, difficulty and frequency of the parameters as well as barriers to their implementation; secondly, in a non-participant observation in five pharmacies to evaluate the actual consultation practice.

Results

In the self-report, all parameters were rated by more than 76% of 1068 participants as important. ‘Concurrent medication’ was determined to be the most difficult parameter to address (54%). All parameters of information gathering were rated to be addressed during routine counselling by at least 70% of the respondents. Parameters of information provision were all rated to be addressed by at least 45%. ‘Lack of patient’s interest’ was identified as the most frequent barrier to appropriate counselling (84%). During the observation, the information gathering parameters were each addressed between 8 to 63% in the consultations, parameters of information provision between 3 to 34%.

Conclusion

Despite broad acceptance, the guideline parameters of information exchange were comparatively little addressed during the actual routine care. This might be due to a perceived ‘lack of patient’s interest’ in counselling. Our results suggest to scrutinize whether patients are in fact not interested in counselling and to further explore how the positive intention of pharmaceutical staff towards information exchange can be further translated into everyday practice.

Conceptualization, Development and Psychometric Evaluations of a New Medication-Related Health Literacy Instrument: The Chinese Medication Literacy Measurement

There is a need for valid and reliable instruments to focus on medication aspects of health literacy and help healthcare professionals address patients’ barriers to medication use. This cross-sectional study describes the conceptualization, development, and psychometric properties of the first Chinese Medication Literacy Measurement (ChMLM) to assess the level of health literacy on medication use. The 17-item ChMLM (ChMLM-17) and its short form, 13-item ChMLM (ChMLM-13), consist of four sections (vocabulary, over-the-counter labels, prescription labels, and advertisements) to cover six domains of medication-related health literacy. Multistage stratified quota sampling was attempted to recruit a representative sample in Taiwan. Receiver operating characteristic curves were used to identify the cut-off point for differentiating high and low medication literacy. Psychometric analyses were performed (n = 1410) to assess the reliability and validity separately on all samples and sociodemographic subgroups. The 17- and 13-item versions both had high construct validity among all patients and patients with low medication literacy. The developed ChMLM-17 and ChMLM-13 is expected to help healthcare providers and researchers to accurately measure medication-related health literacy and improve medication use in the real-world practice.

Effectiveness and cost-effectiveness of treatment with additional enrollment to a homeopathic integrated care contract in Germany

BACKGROUND

A number of German statutory health insurance companies are offering integrated care contracts for homeopathy (ICCHs) that cover the reimbursement of homeopathic treatment. The effectiveness and cost-effectiveness of these contracts are highly debated.

METHODS

To evaluate the effectiveness and cost-effectiveness of treatment after an additional enrollment in an ICCH, a comparative, prospective, observational study was conducted in which participants in the ICCH (HOM group) were compared with matched (on diagnosis, sex and age) insured individuals (CON group) who received usual care alone. Those insured with either migraine or headache, allergic rhinitis, asthma, atopic dermatitis and depression were included. Primary effectiveness outcomes were the baseline adjusted scores of diagnosis-specific questionnaires (e.g. RQLQ, AQLQ, DLQI, BDI-II) after 6 months. Primary cost-effectiveness endpoints were the baseline adjusted total costs from an insurer perspective in relation to the achieved quality-adjusted life years (QALYs). Costs were derived from health claims data and QALYs were calculated based on SF-12 data.

RESULTS

Data from 2524 participants (1543 HOM group) were analyzed. The primary effectiveness outcomes after six months were statistically significant in favor of the HOM group for migraine or headache (Δ = difference between groups, days with headache: - 0.9, p = 0.042), asthma (Δ-AQLQ(S): + 0.4, p = 0.014), atopic dermatitis (Δ-DLQI: - 5.6, p ≤ 0.001) and depression (Δ-BDI-II: - 5.6, p ≤ 0.001). BDI-II differences reached the minimal clinically important difference. For all diagnoses, the adjusted mean total costs over 12 months were higher in the HOM group from an insurer perspective, with migraine or headache, atopic dermatitis and depression suggesting cost-effectiveness in terms of additional costs per QALY gained.

CONCLUSION

After an additional enrollment in the ICCH, the treatment of participants with depression showed minimally clinically relevant improvements. From an insurer perspective, treatment with an ICCH enrollment resulted in higher costs over all diagnoses but seemed to be cost-effective for migraine or headache, atopic dermatitis and depression according to international used threshold values. Based on the study design and further limitations, our findings should be considered cautiously and no conclusions regarding the effectiveness of specific treatment components can be made. Further research is needed to overcome limitations of this study and to confirm our findings.
