This study shows that generic substitution can be an additional factor in poor drug adherence in hypertensive patients and contributes to concerns and confusion among the patients. Although generic substitution is an important measure of cost containment, health personnel should approach each patient individually. Clearly, many patients feel insecure about substituting their medication and demand more information.

Background and ObjectivesGeneric substitution has been introduced in most countries in order to reduce costs and improve access to drugs. However, regulations and the generic drugs available vary between countries. It is the prescriber or dispenser of the drug who is the final decision maker. Nevertheless, physicians’ and pharmacists’ perceptions of generic drug use are not well documented to date. This study presents a systematic review of physicians’ and pharmacists’ perspectives on generic drug use worldwide.MethodsA systematic literature search was performed to retrieve all articles published between 2002 and 2012 regarding physicians’ and/or pharmacists’ experiences with generic drugs and generic substitution.ResultsOf 1322 publications initially identified, 24 were eligible for inclusion. Overall, the studies revealed that physicians and pharmacists were aware of the cost-saving function of generic drugs and their role in improving global access to drugs. Nevertheless, marked differences were observed between countries when studying physicians’ and pharmacists’ perceptions of the available generic drugs. In less mature healthcare systems, large variations regarding, for example, control routines, bioequivalence requirements, and manufacturer standards were reported. A lack of reliable information and mistrust in the efficacy and quality were also mentioned by these participants. In the most developed healthcare systems, the participants trusted the quality of the generic drugs and did not hesitate to offer them to all patients regardless of socioeconomic status. In general, pharmacists seemed to have better knowledge of the concept of bioequivalence and generic drug aspects than physicians.ConclusionsThe present study indicates that physicians and pharmacists are aware of the role of generic drugs in the improvement of global access to drugs. However, there are marked differences regarding how these health professionals view the quality of generic drugs depending on the maturity of their country’s healthcare system. This can be attributed to the fact that developed healthcare systems have more reliable public control routines for drugs in general as well as better bioequivalence requirements concerning generics in particular.

PurposeThis study aims to explore how long-term drug users with a Pakistani background living in Oslo (Norway) perceive generic substitution and how generic substitution influences drug adherence in this population.MethodsPersonal interviews using a semi-structured questionnaire were carried out with 83 Pakistani immigrants (aged 40–80 years) who were using antihypertensives, antidiabetics, and/or cholesterol-lowering drugs.ResultsIn all, 73% of the participants were using generic drugs at the time of the interview. Of these, 10% were erroneously using two equivalent generics at the same time. One quarter of the participants were of the opinion that cheaper generic drugs were counterfeit drugs. Two thirds had accepted generic substitution in the pharmacy whereas the remaining participants had either opposed or were unaware of the substitution. Of those who had accepted substitution, 27% claimed that the effect of the new drug was poorer and 20% reported more side-effects. Generic substitution had resulted in concerns about the therapy in 41% of the patients, and 26% thought it had become more demanding to keep track of their medication. Poor adherence tended to be most common among patients who were not fluent in Norwegian, patients who had concerns about medicine use, and patients who had accepted generic substitution in the pharmacy.ConclusionThis study shows that generic substitution may have a negative effect on drug adherence in Pakistani immigrants in Oslo (Norway) because of concerns and misconceptions, including confusion with regard to counterfeit drugs. Problems result primarily from inadequate information caused by language barriers but also from culturally conditioned views on encounters with the health care system.

BackgroundThis 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.MethodThe 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.ResultsEach 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.ConclusionsIn 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.

ObjectivesThe aim of this study was to investigate experiences with and attitudes toward generic substitution in patients on antihypertensive medication.Materials and methodsStudy participants were 22 patients from pharmacies in Oslo who had taken brand antihypertensive products as well as substituted generic products. Five focus- group discussions were held.ResultsOnly a few participants claimed to take their medications as prescribed. Most reported low drug adherence before and after generic substitution. Fourteen said that their blood pressure was not under control. Most patients did not know what it meant to get a generic product. They normally accepted what the pharmacy offered, even if they thought the generics were of a lower quality than the brand products. Five participants experienced new side effects. Differences in name, color, form, or taste caused confusion. The patients had been told in the pharmacy that the effect of a generic product was as good as that of the brand product but were still confused, as in most cases the doctor said nothing to them about the substitution.ConclusionGeneric substitution works well in Norway as an economic health strategy, but drug adherence remains suboptimal under those circumstances. Patients are insecure with respect to the difference between the old and the new product when it comes to the drug’s physical attributes and perceived quality. Patients would feel safer if the doctor had a more active role in informing them about the system.

This study shows that cultural influences may affect medicine use among first-generation immigrants from Pakistan after having lived 10 years or more in Norway. Although access to drugs and basic health care services seems to be problem free, language proficiency is a considerable problem that obstructs access to information and is detrimental to the level of communication with health professionals.
