Objective: To investigate preferences among university students in Gothenburg, Sweden for medicines that have a different environmental impact with respect to effect and explore to what extent having received information about pharmaceuticals’ potential harm to the environment is associated with the stated preferences. Methods: A survey was conducted among students in different study programs at the University of Gothenburg, Sweden. In all, 704 students received oral and written information about the study at the end of a lecture and were invited to take part (response rate: 83.5%). The questionnaire contained items about medicinal environmental information and two scenarios with fictious medicines as options for the treatment or symptom relief of minor ailments in humans. Results: Overall, 53.3% of the students (pharmacy students: 57.8%) had received information about the environmental impact of medicines, and 79.6% (pharmacy students: 80.6%) reported that they had concerns about the consequences. Twenty percent (pharmacy students: 9.0%) named the university as an information source. The students were most satisfied overall with the least effective and most environmentally friendly medicines. Consistently, pharmacy students gave higher scores to the most environmentally harmful medicines, especially when compared with medical and healthcare students. Pharmacy students, who, to the same extent as medical and healthcare students had received information about medicines’ environmental impact, were less likely to state environmentally friendly options with an inferior effect as their preferred choice. Conclusion: Pharmacy students generally rated the medicines higher than other student groups, despite being aware of the harmful effects on the environment.

Use of pharmaceuticals is continuously increasing globally and their residues are recognized as a risk for the environment. The aim of this study was to investigate drug utilization patterns of analgesics in relation to environmental hazard in the region surrounding Sweden's largest drinking water source, Lake Mälaren. This was examined using sales data on pharmaceuticals from the Swedish E-health Agency. The total sales of analgesics (non-steroidal anti-inflammatory drugs, paracetamol, other non-opioid analgesics, and opioids) for both human and veterinary use in the region were analyzed for the years 2016 to 2020, in relation to the inherent environmental hazard for each active pharmaceutical ingredient (API). We found that a total of 454 tons of analgesics were sold in the region during these 5 years. Classifications of environmental hazard were available for 16 out of the 45 studied APIs, accounting for 98.8% of the total mass in kilograms. Paracetamol, ibuprofen, and acetylsalicylic acid, which are all classified as low-hazard compounds, were the most commonly sold APIs. Diclofenac, the only pharmaceutical classified as high-hazard, was the fifth most commonly sold API, with a total sold mass of 2321 kg. The majority of the total sold mass of analgesics originated from dispensed prescriptions for human use in urban areas. Visualization of drug sales for humans and animals in different settings can be used to identify the environmental burden of pharmaceuticals. Based on our study, we suggest that additional measures to reduce the impacts of pharmaceuticals on the environment should primarily be directed to prescribing physicians in urban areas and campaigns targeted at the high over-the-counter sales of diclofenac. Moreover, it is important to address the fact that many pharmaceuticals currently have limited data on environmental hazard.

Background: Despite increased insight into the harmful effects medicines have on the environment, research is scarce on how this awareness affect consumer behaviour and how people would react to environmental policies that could influence individual treatment options. Objectives: To investigate if information about environmental harm would affect people's medicine choices and the support of policies to reduce pharmaceutical pollution. Methods: A web survey was completed by a representative sample of the Swedish adult population (n=1,583). The survey included a choice task with three disease scenarios (common cold, rheumatoid arthritis, and stroke) and fictitious medicines with different therapeutic effect and environmental harm. There were also items asking for support of possible policies (eco-labelling of over-the-counter (OTC) medicines, higher prices for environmentally harmful medicines, and green prescribing requirements). Results: The most environmentally friendly and least effective options were preferred by 68% of the participants in the common cold scenario, 36% in the rheumatoid arthritis scenario, and 23% in the stroke scenario. These were rated highest in satisfaction with treatment option for the common cold (large effect) and rheumatoid arthritis (small effect) scenarios. Regarding stroke, the most effective and least environmentally friendly options were most preferred. Reported support of policies were consistently high. The highest was the support of eco-labelling of OTC medicines, followed by higher prices for environmentally harmful medicines, and green prescribing requirements (in that order). Female sex, age ≥ 60 years, higher education and having no children were associated with being positively inclined towards the most intrusive regulation (green prescribing requirements). Conclusion: There is a willingness among people in Sweden to take environmental considerations into account for minor ailments, which gradually disappears when faced with more serious diseases. Swedes support policies that could lead to more environmentally friendly medicine use, including those that affect individual treatment options.

Background Self-report by questionnaire is one of the main methods to collect data on drug utilization. There are several modes of data collection by questionnaire, differing in the way of delivering the questionnaire to respondents and in the administration of the questions, both influencing the recall and participation rates. The aim of this study was to compare different modes of data collection for self-reported use of non-steroidal anti-inflammatory (NSAIDs) and analgesic medicines. Methods Data on 573 women (38 or 50 years) were retrieved from the Population Study of Women in Gothenburg. Data on medicine use were collected using two different modes: (1) a self-administered questionnaire with closed-ended medicine-specific questions; and (2) an interviewer-administered questionnaire with open-ended questions. Cohen’s kappa statistics were applied to assess the agreement of the two modes. Results The proportion of participants that reported use of NSAIDs and analgesics was higher with the self-administered questionnaire compared with the interviewer-administered questionnaire (69.3% vs 58.5%, p <0.001). The overall agreement between the two modes of data collection was fair (Ⱪ=0.27), ranging from none for antimigraine preparations to fair (Ⱪ=0.36) for NSAIDs. A higher proportion of the participants aged 38 years reported use of NSAIDs and analgesics compared with the 50-year olds. In the regression model using data from the self-administered questionnaire, all four categories of bodily pain were significant predictors for use of NSAIDs and analgesics. The most severe reported bodily pain was the only significant predictor in the model using data from the interviewer-administered questionnaire. Conclusion This study showed that use of a self-administered questionnaire with closed-ended medicine-specific questions identified more users of NSAIDs and analgesic medicines compared with an interviewer-administered questionnaire with open-ended questions. Reported use according to the self-administered questionnaire was also more strongly associated with experienced pain.

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.

Background: Asthma is an extensive public health problem and inadequate disease control is not uncommon. Individuals' self-perceived barriers to medical treatment for the entire treatment chain (from seeking care for symptoms to using a medicine) have seldom been studied for chronic diseases such as asthma. The aim of this study was to explore self-perceived barriers to medical treatment among individuals with asthma within the framework of AAAQ (availability, accessibility, acceptability and quality). Methods: Individuals with asthma visiting the asthma nurse at a primary health care centre, and who currently had a prescription for anti-asthmatic medicines, were informed about the study. The nurse asked the persons for their consent to be contacted by an interviewer. The interview guide was constructed from the elements of AAAQ exploring self-perceived barriers to asthma treatment. Interviews were conducted in Swedish, English, Arabic and Persian. They were transcribed verbatim and a manifest content analysis was conducted. Results: Fourteen interviews were conducted. There was a large variation in both age and reported number of years with asthma. Self-perceived barriers to asthma treatment were experienced throughout the whole treatment chain. Barriers that emerged were health care accessibility, perceived quality of care, beliefs about medicines, life circumstances, knowledge gap about asthma and medicines, practical obstacles to using medicines, and experiences with treatment. The self-perceived barriers cover all four elements of AAAQ, but there are also some barriers that go beyond those elements (life circumstances and practical obstacles to using medicines). Conclusions: Self-perceived barriers among individuals with asthma cover the whole treatment chain. We want to highlight the inadequate information/education of patients leading to knowledge gaps about both disease and the effect of medicines, and also the perceived unsatisfactory treatment at the PHCC, which could partly be counteracted if patients know what to expect from health care visits.

Objective: To explore the experiences of immigrant Kurdish patients in Oslo, Norway, related to the management of type 2 diabetes mellitus (T2DM). Design: A qualitative study with focus group interviews. Setting: Participants were recruited at meeting places in Oslo through Kurdish networks. Subjects: Eighteen Kurdish immigrants (9 females and 9 males) living in Oslo, aged 40 to 64 years, diagnosed with T2DM participated in a total of five focus groups. Participants had to be proficient in the Norwegian language to be eligible. Main outcome measures: Immigrant Kurdish patients’ experiences with being diagnosed with T2DM, their disease management, and need for medical information. Results: Participants stressed that living with T2DM was emotionally challenging, mainly because they were afraid of possible complications of the disease. They claimed to adhere satisfactorily to their medicines and blood glucose measurements. The majority of participants shared that they had made changes to their diet, even though it was difficult. To the contrary, physical activity received only minimal attention. The participants’ main source of information was general practitioners and the majority of them were satisfied with the information that they had received about their disease and its management. Conclusion: Kurdish T2DM patients in the present study from Norway reported that they adhered to the medical treatment, even if they were stressed about living with the disease. However, they were more occupied with changing their diet than to be physically active. Therefore, healthcare personnel should try to be aware of lifestyle challenges among their patients. • KEY POINTS • Eighteen Kurdish patients in Oslo with Type 2 diabetes claimed to be adherent to medication treatment and blood glucose measurement. • The participants shared that they had made changes to their diet, even though it was hard. • There was generally little attention given to the need for physical activity in their daily lives. • The participants were in need of more information and support in making healthy lifestyle changes.

The prevalence of Type 2 diabetes (T2D) among Pakistani women in Norway is remarkably high. This study aims to assess how they live with the disease and their response to lifestyle and medical information. 120 Pakistani women living in Norway (mean age: 55.7 years) were personally interviewed about their T2D using a structured questionnaire (response rate: 95%). The participants were first-generation immigrants (mean residence time: 28.7 years) of whom 27% were illiterates. Poor health was reported by one-third, and 71% had developed macrovascular comorbidities. A majority reported physical inactivity and an unhealthy diet included religious fasting. One-third was not able to self-measure their blood glucose. There was a great variation in antidiabetic drug regimens and one-fourth had to use insulin in addition to tablets. Pakistani women in Norway showed suboptimal control of their T2D in terms of lifestyle habits, comorbidities and drug use. Low literacy and cultural factors seem to challenge adherence to lifestyle and medical information.

Background This project aims to study the use of antibiotics in three clinical wards in the largest tertiary teaching hospital in Ethiopia for a period of 1 year. The specific aims were to assess the prevalence of patients on antibiotics, quantify the antibiotic consumption and identify the main indications of use. Method The material was all the medical charts (n = 2231) retrieved from three clinical wards (internal medicine, gynecology/obstetrics and surgery) in Tikur Anbessa Specialized Hospital (TASH) in Addis Ababa between September 2013 and September 2014. Data collection was performed manually by four pharmacists. Results Each medical chart represented one patient. About 60% of the patients were admitted to internal medicine, 20% to each of the other two wards. The number of bed days (BD) was on average 16.5. Antibiotics for systemic use were prescribed to 73.7% of the patients (on average: 2.1 antibiotics/patient) of whom 86.6% got a third or fourth generation cephalosporin (mainly ceftriaxone). The average consumption of antibiotics was 81.6 DDD/100BD, varying from 91.8 in internal medicine and 71.6 in surgery to 47.6 in gynecology/obstetrics. The five most frequently occurring infections were pneumonia (26.6%), surgical site infections (21.5%), neutropenic fever (6.9%), sepsis (6.4%) and urinary tract infections (4.7%). About one fourth of the prescriptions were for prophylactic purposes. Hospital acquired infections occurred in 23.5% of the patients (353 cases of surgical site infection). The prescribing was based on empirical treatment and sensitivity testing was reported in only 3.8% of the cases. Conclusions In the present study from three wards in the largest tertiary teaching hospital in Ethiopia, three out of four patients were prescribed antibiotics, primarily empirically. The mean antibiotic consumption was 81.6 DDD/100BD. Surgical site infections constituted a large burden of the infections treated in the hospital, despite extensive prescribing of prophylaxis. The findings show the need to implement antibiotic stewardship programs in Ethiopian hospitals with focus on rational prescribing, increased sensitivity testing and better procedures to prevent hospital acquired infections.

Objectives To analyse attitudes towards sales and use of over‐the‐counter (OTC) drugs in the Swedish adult population. Methods Data were collected through the web‐based Citizen Panel comprising 21 000 Swedes. A stratified sample of 4058 participants was emailed a survey invitation. Questions concerned use of OTC drugs, and attitudes towards sales and use of OTC drugs. Correlations between the attitudinal statements were assessed using Spearman's rank correlation. Associations between attitudes and participant characteristics were analysed using multinomial logistic regression. Key findings Participation rate was 64%. Altogether 87% reported use of OTC drugs in the last 6 months. Approximately 10% of participants stated that they used OTC drugs at the first sign of illness, and 9% stated that they used more OTC drugs compared with previously, due to increased availability. The statement on use of OTC drugs at first sign of illness correlated with the statement about using more OTC drugs with increased availability. Socio‐demographic factors (age, sex and education) and frequent use of OTC drugs were associated with attitudes to sales and use of OTC drugs. Conclusions Increased use due to greater availability, in combination with OTC drug use at first sign of illness illustrates the need for continuous education of the population about self‐care with OTC drugs. Increased awareness of the incautious views on OTC drugs in part of the population is important. Swedish policy‐makers may use such knowledge in their continuous evaluation of the 2009 pharmacy reform to review the impact of sales of OTC drugs in retail outlets on patient safety and public health. Pharmacy and healthcare staff could be more proactive in asking customers and patients about their use of OTC drugs and offering them advice.
