Generic medicines: Greek physicians' perceptions and prescribing practices

Opinion of Polish Patients with Epilepsy on Generic Medications

AIM

The majority of medicines used in Poland are generic drugs and substitutions of the originals. The objective of this study was to obtain information on the current knowledge about generic medicines among Polish patients with epilepsy.

MATERIAL AND METHODS

The conducted study was based on a self-developed questionnaire. The questionnaire consisted of 26 questions, including the questions regarding the respondents' knowledge about generics, their previous experience, and the factors behind these choices.

RESULTS

Overall, 1220 questionnaires were analyzed. Among all patients, 66.4% reportedly had heard about generics. Of these, 61.5% of patients had used generic drugs in the past. A significant proportion of participants had never been recommended to switch to a generic medicine by their healthcare professional (23% physicians and 13.9% pharmacists). Statistically, relevant differences were observed regarding the respondents' kind and level of education, place of residence, and net income per household.

CONCLUSIONS

Significant gaps were identified in the knowledge and perceptions among patients regarding generic medicines, especially in relation to their efficacy and safety. Efforts must be directed towards increasing public awareness of generic medicines and there should also be a focus on educating patients about generic medicines.

Disentangling prescribing behaviour of Cypriot physicians, within a complex framework of interacting

The purpose of the study is to investigate how physicians' prescribing behaviour in Cyprus adopts to the fragmented healthcare system and to the inadequacies of pharmaceutical market in times of economic crisis. A survey was carried out in using a postal questionnaire administered to a stratified sample of 320 physicians. The questionnaire used was the same with the one used in 2007 survey carried out in Greece and Cyprus, along with complementary questions for prescribing within economic crisis. The comparative analysis and assessment of the findings from the two surveys revealed that the current system and the inadequacies of pharmaceutical market in Cyprus expose physicians to a contrasting environment of public and private sector in terms of incentives, governance principles, financing and market structure. In contrast to public sector prescribers who have behaved in accordance with the governance principles, there is a strong motivation for private sector physicians to favour new branded products, and generally rejecting any ideas that could limit their clinical autonomy. Economic crisis seems to be unilaterally influential, as public sector physicians became more cost conscious while private sector prescribing is still resisting due to strong financial incentives.

Prescribing behaviour of physicians in Cyprus amid economic crises.

Pressures by patients, policy makers and pharma companies shape prescribing behaviour.

Disentangling prescribing behaviour could lead to the revelation of opportunities for improvements.

Differential prescribing could justify that decision‐making might be compromised for economic reasons.

Physicians' Knowledge, Attitude and Practice of Generic Substitution in China: A Cross-Sectional Online Survey

The purpose of this study is to investigate physicians’ knowledge, attitudes and practice of generic medicine substitutions in China. We conducted a cross-sectional online questionnaire survey on physicians from secondary or tertiary hospitals in China from 2020 December to 2021 April. Descriptive statistical and ordered logistic regression were used for analysis. A total of 1225 physicians were included in the final analysis, and only 330 (26.94%) of them scored 4 or above in the knowledge part, which means that the physicians have a good knowledge of generic substitutions. Of the total, 586 (47.83%) agreed or strongly agreed that generic drugs could be substituted for originator drugs and 585 (47.75%) always or often prescribed generic medicines. The percentage of physicians with a positive attitude toward or that practice prescribing generic medicine is below 50%, which needs to be improved in China. Physicians’ knowledge, their attitude toward generic substitution, if familiar with the policy of generic substitution, and incentives for prescribing generic medicines are influencing factors for the practice of generic substitution. Our studies show that the practice of generic substitution by physicians could be improved by several measures in China. We suggested that the physicians should be taught more about the bulk-buy policy and the generic-originator equivalence evaluation policy. Moreover, government incentives to promote generic substitution should be established. Our study also suggested that physicians with less working experience and female physicians should learn more about generic substitution.

Medical staff perspective on factors influencing their prescribing decisions: a cross-sectional study in Mekong Delta, Vietnam

Objectives

Understanding medical staff’s prescription behaviors helps improve the quality of prescriptions and the rationality of medication use. Although factors affecting the prescribing decisions were discussed in various studies worldwide, limited knowledge of these issues has been reported in Vietnam. This paper aims to examine factors that influence prescribing behavior concerning medical staff’s demographics and characteristic differences.

Methods

Quantitative descriptive cross-sectional study, using adapted questionnaire consisting of 27 factors divided into 9 factor categories, was conducted with medical staff in Mekong Delta during June–July, 2019. Rasch analysis was performed to assess the questionnaire psychometric properties. Descriptive analysis, parametric tests and non-parametric tests were utilized to address the study objectives.

Key findings

A total of 201 participants completed the questionnaire. A majority of participants (>90%) agreed that their own decision to prescribe a drug was influenced by several factors such as drug safety and efficacy (92.5%), patient history (92.0%), patient income (92.0%) and patient disease status (91.0%). There were significant age differences in influences on prescribing decision. Medical staff aged under 30 appreciated the role of pharmacists higher than whose aged 31–40 (P-value = 0.010) and over 40 (P-value = 0.013). Additionally, they were more concerned with ‘patient characteristics’ including patient request, expectations, and disease status when making prescribing decisions compared with whose aged over 40 (P-value = 0.005).

Conclusions

The study revealed various factors influencing medical staff prescription decision-making processes. These findings could be useful for pharmaceutical companies in Vietnam in developing marketing strategies, and for policy-makers in timely improvement of prescription quality.

Exploring knowledge and perceptions on generic drugs of final year pharmacy school students in Greece

Objectives: The economic crisis in Greece has triggered an extensive public debate about the use of generic drugs (generics). Despite their cost-saving potential, generic market penetration remains very low. This raises questions on awareness of, perception on and preference for generics by health-care professionals and patients. This is a descriptive study on the level of knowledge and attitudes towards generics of final year pharmacy school students in Greece. Methods: An electronic questionnaire was distributed to 173 senior pharmacy school students in three Universities in Greece. Responses were submitted electronically. Results: The majority of students knew that generics contain the same active ingredient as the originator products and are cheaper. Students were somehow concerned with safety and efficacy of generics. The majority of students agreed that pharmacists should probably recommend the use of generics, and indicated that prescribing and dispensing practices would largely depend on the profit margin. Despite more than half of the students expressing a positive attitude towards generics, they were inadequately educated on their features. Conclusion: It is critical to improve knowledge of and preference for generics amongst health-care professionals from early on if to build the trust required to increase generic market penetration and achieve measurable savings in pharmaceutical expenditure.

Greek students' attitudes, perception and knowledge regarding generic medicines in times of economic crisis: a cross-sectional study

BACKGROUND

The penetration of generic medicines in the pharmaceutical market is influenced, among others, by the consumer's attitude upon them. The attitude of students in health management and recent alumni is particularly important, as they constitute tomorrow's policymakers. The aim of our study was to assess their attitude, perception and knowledge towards generic medicines.

METHODS

A cross-sectional study was undertaken, involving students in Health Management and recent alumni. The ATtitude TOwards GENerics (ATTOGEN) validated questionnaire was used, which consists of 18 items, yielding 6 scales (trust, state audit, knowledge, drug quality, drug substitution and fiscal impact), with all item responses expressed on a 5-point Likert scale and higher scores denoting greater disagreement. Correlation coefficients were computed and independent sample tests were performed using non-parametrical statistical methods.

RESULTS

A total of 1402 students were interviewed, with a female predominance (62.88%). The mean (SD) scores for the six scales of the ATTOGEN questionnaire were: Trust: 2.877 (0.940), State audit: 3.251 (0.967), Knowledge: 1.537 (0.688), Drug quality: 2.708 (0.971), Drug substitution: 3.828 (1.127) and Fiscal impact: 2.299 (0.860). Trust over generics was statistically significantly associated with all ATTOGEN scales (all p < 0.001). In addition, the increased level of knowledge about generics was associated with recognition of the generic medicines' quality equivalence (p < 0.001) and positive fiscal impact (p = 0.018). Pharmacists declared having a superior knowledge of generic medicines, being more satisfied with the information they receive about them and strongly believing in drug substitution (p < 0.001). Comparatively to other professionals, pharmacists also indicated substantial differences between branded and generic medicines more often (p < 0.001). They also argued to a greater extent that generic medicines were invented and promoted to resolve the financial crisis of social security institutions at the expense of citizens (p < 0.001).

CONCLUSIONS

This study demonstrated a mixed attitude of students regarding generic medicines. Trust and knowledge emerged as key factors shaping the students' attitude towards generics. Among students, pharmacists exhibited a distinct response pattern. This study underlines the importance of addressing and correcting health management students' misbeliefs about generics' quality and utility.

Policies and perceptions on generic drugs: The case of Greece

The increase in the consumption of generic drugs to reduce pharmaceutical expenditure is a challenge for many countries, especially during the economic crisis. The purpose of the present study is to review the Greek market of generic drugs and the decisions that shape it, to determine the factors that affect Greek patients' and doctors' attitudes about generic substitution and present a set of measures for all stakeholders based on the findings of the secondary and primary analysis. The study includes (a) an analysis of international and national reports and legislation on drugs policies and (b) a questionnaire survey of 242 hospital patients and 85 doctors regarding their perceptions on generics. A small increase in the volume of generics is recorded, yet not followed by sales value, over the recent years that the measures for promoting generics prescription took effect. Distrust from both patients and doctors was observed toward generics' effectiveness and toward the appropriateness of the regulatory authorities' quality controls. The study presents a structured set of viable measures, applicable to many countries, for promoting generic drug consumption that can lead to economic efficiency without degrading the health care quality.

Development and validation of a tool to assess knowledge and attitudes towards generic medicines among students in Greece: The ATtitude TOwards GENerics (ATTOGEN) questionnaire

INTRODUCTION

The use of generic medicines is a cost-effective policy, often dictated by fiscal restraints. To our knowledge, no fully validated tool exploring the students' knowledge and attitudes towards generic medicines exists. The aim of our study was to develop and validate a questionnaire exploring the knowledge and attitudes of M.Sc. in Health Care Management students and recent alumni's towards generic drugs in Greece.

MATERIALS AND METHODS

The development of the questionnaire was a result of literature review and pilot-testing of its preliminary versions to researchers and students. The final version of the questionnaire contains 18 items measuring the respondents' knowledge and attitude towards generic medicines on a 5-point Likert scale. Given the ordinal nature of the data, ordinal alpha and polychoric correlations were computed. The sample was randomly split into two halves. Exploratory factor analysis, performed in the first sample, was used for the creation of multi-item scales. Confirmatory factor analysis and Generalized Linear Latent and Mixed Model analysis (GLLAMM) with the use of the rating scale model were used in the second sample to assess goodness of fit. An assessment of internal consistency reliability, test-retest reliability, and construct validity was also performed.

RESULTS

Among 1402 persons contacted, 986 persons completed our questionnaire (response rate = 70.3%). Overall Cronbach's alpha was 0.871. The conjoint use of exploratory and confirmatory factor analysis resulted in a six-scale model, which seemed to fit the data well. Five of the six scales, namely trust, drug quality, state audit, fiscal impact and drug substitution were found to be valid and reliable, while the knowledge scale suffered only from low inter-scale correlations and a ceiling effect. However, the subsequent confirmatory factor and GLLAMM analyses indicated a good fit of the model to the data.

CONCLUSIONS

The ATTOGEN instrument proved to be a reliable and valid tool, suitable for assessing students' knowledge and attitudes towards generic medicines.

Perceptions of generic medication in the general population, doctors and pharmacists: a systematic review

OBJECTIVE

To investigate negative perceptions about generic medicines and evaluate the proportions of lay people, doctors and pharmacists who hold these perceptions.

DESIGN

A systematic review of observational studies.

DATA SOURCES

MEDLINE, EMBASE, PsycInfo and Scopus.

ELIGIBILITY CRITERIA

Quantitative data from cross-sectional and prospective studies published in English after 1980, using self-report measures to evaluate perceptions about generic medicines, presented as percentages of the total sample assessed.

RESULTS

After screening 2737 articles, 52 articles were included in the final analysis. A high proportion of doctors, pharmacists and lay people had negative perceptions of generics. Lay people were significantly more likely to view generics as less effective than branded medication (35.6%, 95% CI 34.8% to 36.4%) compared to doctors (28.7%, 27.5% to 29.9%) and pharmacists (23.6%, 21.2% to 26.2%), p<0.0001. Pharmacists (33.4%, 31.0% to 35.9%) were significantly more likely to believe generics were of inferior quality compared to branded medication than were doctors (28.0%, 26.3% to 29.9%), p=0.0006, and lay people (25.1%, 24.2% to 26.0%), p<0.0001. Doctors believed generics caused more side effects than branded medication (24.4%, 22.2% to 26.9%), compared to pharmacists (17.6%, 15.3% to 20.1%) and lay people (18.8%, 17.8% to 19.8%), p<0.0001. Doctors (28.5%, 26.9% to 30.2%) and pharmacists (25.4%, 21.4% to 29.9%) had significantly more safety concerns about generics than did lay people (18.0%, 17.0% to 19.0%), p ≤ 0.0002. A greater proportion of lay people felt negatively about generic substitution (34.0%, 33.2% to 34.9%), compared to doctors (24.1%, 22.0% to 26.4%) and pharmacists (11.0%, 9.6% to 12.7%), p<0.0001. Rates of negative perceptions of generics do not appear to have changed substantially over time in the general population or among physician groups, p ≥ 0.431, but such negative beliefs show a decreasing trend in pharmacists over the study period, p=0.034.

CONCLUSIONS

A significant proportion of doctors, pharmacists and lay people hold negative perceptions of generic medicines. It is likely these attitudes present barriers to the wider use of generics.

Greek Physicians' Perceptions on Generic Drugs in the Era of Austerity

Purpose. To assess the beliefs and preferences of Greek physicians, regarding generic drugs, in the years of financial crisis. Setting. Multicentered, nationwide survey. Material and Methods. A custom questionnaire based on former similar studies was developed and administered to Greek physicians. The variable "perception on generics" was constructed after an exploratory study and the instrument was validated by conventional and Rasch analysis methods. 22 items formed 5 subscales that constructed the variable in question. Results. 908 physicians successfully participated in the study (response rate: 80%). Mean total scores to the instrument were 60.63 ± 12.12 for men and significantly less (58.24 ± 11.73) for women (p = 0.04). Greek physicians were not persuaded on the potential economic gain (45.79 ± 10.53); moreover they identified that Greek authorities cannot address the increased pharmacovigilance mandates. Physicians working in Athens and those working in surgical units demonstrated significantly worse scores than their colleagues from the rest of Greece and those working in Internal Medicine wards (p = 0.03).  Conclusion. Our results suggest an overall poor acceptance of the national initiative on generic drugs by Greek physicians. This trial is registered with Clinicaltrials.gov identifier: NCT01855802.

Estimating the Fiscal Effects of Public Pharmaceutical Expenditure Reduction in Greece

The purpose of the present study is to estimate the impact of pharmaceutical spending reduction on public revenue, based on data from the national health accounts as well as on reports of Greece’s organizations. The methodology of the analysis is structured in two basic parts. The first part presents the urgency for rapid cutbacks on public pharmaceutical costs due to the financial crisis and provides a conceptual framework for the contribution of the Greek pharmaceutical branch to the country’s economy. In the second part, we perform a quantitative analysis for the estimation of multiplier effects of public pharmaceutical expenditure reduction on main revenue sources, such as taxes and social contributions. We also fit projection models with multipliers as regressands for the evaluation of the efficiency of the particular fiscal measure in the short run. According to the results, nearly half of the gains from the measure’s application is offset by financially equivalent decreases in the government’s revenue, i.e., losses in tax revenues and social security contributions alone, not considering any other direct or indirect costs. The findings of multipliers’ high value and increasing short-term trend imply the measure’s inefficiency henceforward and signal the risk of vicious circles that will provoke the economy’s deprivation of useful resources.

A Systematic Review of Physicians' and Pharmacists' Perspectives on Generic Drug Use: What are the Global Challenges?

BACKGROUND AND OBJECTIVES

Generic 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.

METHODS

A 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.

RESULTS

Of 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.

CONCLUSIONS

The 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.

The Impact of Generic Substitution on Health and Economic Outcomes: A Systematic Review

BACKGROUND

Generic drugs are considered therapeutically equivalent to their original counterparts and lower in acquisition costs. However, the overall impact of generic substitution (GS) on global clinical and economic outcomes has not been conclusively evaluated.

OBJECTIVE

To test whether (1) generics and original products yield the same health outcomes, and (2) generic therapies save economic resources versus original therapies.

METHODS

We performed a systematic literature review in Medline, Embase, and the Cochrane Database of Systematic Reviews to identify original studies that examine clinical or economic outcomes of GS. After standardized data extraction, reported outcomes were categorized as supporting or rejecting the hypotheses. Each reported outcome was assessed and accounted for supporting and opposing GS. One publication could provide multiple outcome comparisons.

RESULTS

We included 40 studies across ten therapeutic areas. Fourteen studies examined patients on de novo therapy; 24 studies investigated maintenance drug therapy, and two studies considered both settings. Overall, 119 outcome comparisons were examined. Of 97 clinical outcome comparisons, 67% reported no significant difference between generic drugs and their off-patent counterparts. Of 22 economic comparisons, 64% suggested that GS increased costs. Consequently, hypothesis (1) was supported but hypothesis (2) was not. We found no major differences among studies that investigated clinical outcomes with de novo or maintenance therapy.

CONCLUSION

The review suggests that clinical effects are similar after GS. However, economic savings are not guaranteed. More systematic research comparing clinical and economic outcomes with or without GS is needed to inform policy on the use of generic substitution.

What do people really think of generic medicines? A systematic review and critical appraisal of literature on stakeholder perceptions of generic drugs

BACKGROUND

Considerable emphasis is presently being placed on usage of generic medicines by governments focussed on the potential economic benefits associated with their use. Concurrently, there is increasing discussion in the lay media of perceived doubts regarding the quality and equivalence of generic medicines. The objective of this paper is to report the outcomes of a systematic search for peer-reviewed, published studies that focus on physician, pharmacist and patient/consumer perspectives of generic medicines.

METHODS

Literature published between January 2003 and November 2014, which is indexed in PubMed and Scopus, on the topic of opinions of physicians, pharmacists and patients with respect to generic medicines was searched, and articles within the scope of this review were appraised. Search keywords used included perception, opinion, attitude and view, along with keywords specific to each cohort.

RESULTS

Following review of titles and abstracts to identify publications relevant to the scope, 16 papers on physician opinions, 11 papers on pharmacist opinions and 31 papers on patient/consumer opinions were included in this review. Quantitative studies (n = 37) were the most common approach adopted by researchers, generally in the form of self-administered questionnaires/surveys. Qualitative methodologies (n = 15) were also reported, albeit in fewer cases. In all three cohorts, opinions of generic medicines have improved but some mistrust remains, most particularly in the patient group where there appears to be a strongly held belief that less expensive equals lower quality. Acceptance of generics appears to be higher in consumers with higher levels of education while patients from lower socioeconomic demographic groups, hence generally having lower levels of education, tend to have greater mistrust of generics.

CONCLUSIONS

A key factor in improving confidence in generic products is the provision of information and education, particularly in the areas of equivalency, regulation and dispelling myths about generic medicines (such as the belief that they are counterfeits). Further, as patient trust in their physician often overrules their personal mistrust of generic medicines, enhancing the opinions of physicians regarding generics may have particular importance in strategies to promote usage and acceptance of generic medicines in the future.

Factors affecting the opinions of family physicians regarding generic drugs--a questionnaire based study

A range of factors are believed to exert a negative influence on opinions of physicians about generic drugs.The aim of this study was to survey the opinions of primary care doctors on generics, and determine the factors which may affect them. A questionnaire comprising thirty eight questions was distributed among primary care doctors working in seventy out-patient clinics of the Lodzkie province, Poland, during the period of January 1, 2010 - December 31, 2010. A total of 170 of 183 participants completed the survey (average age 48.5; 70.0% women): a 92.9% response rate. While 38.8% of physicians claimed that generics were worse than brand name drugs, 54.1% considered them to be better. However, 36.5% of the doctors did not choose generics for their own use. Two key opinions were identified among the responses concerning the effectiveness of generic drugs: use of generic drugs by the physician (p<0.001), and their opinion that pharmacists do inform patients about generic drugs (p<0.05). Although existing evidence confirms that generic and brand name drugs are equally effective, many physicians doubt this, which prevents them from being used as cost effective drug therapy. In order to increase healthcare savings through the use of generics, these factors should be addressed: for example, convincing a physician to adopt generics for personal use may be an efficient way to support more cost effective treatment of his patients.

Does educational intervention improve doctors' knowledge and perceptions of generic medicines and their generic prescribing rate? A study from Malaysia

Objectives:

To investigate the impact of an educational intervention on doctors’ knowledge and perceptions towards generic medicines and their generic (international non-proprietary name) prescribing practice.

Methods:

This is a single-cohort pre-/post-intervention pilot study. The study was conducted in a tertiary care hospital in Perak, Malaysia. All doctors from the internal medicine department were invited to participate in the educational intervention. The intervention consisted of an interactive lecture, an educational booklet and a drug list. Doctors’ knowledge and perceptions were assessed by using a validated questionnaire, while the international non-proprietary name prescribing practice was assessed by screening the prescription before and after the intervention.

Results:

The intervention was effective in improving doctors’ knowledge towards bioequivalence, similarity of generic medicines and safety standards required for generic medicine registration (p = 0.034, p = 0.034 and p = 0.022, respectively). In terms of perceptions towards generic medicines, no significant changes were noted (p > 0.05). Similarly, no impact on international non-proprietary name prescribing practice was observed after the intervention (p > 0.05).

Conclusion:

Doctors had inadequate knowledge and misconceptions about generic medicines before the intervention. Moreover, international non-proprietary name prescribing was not a common practice. However, the educational intervention was only effective in improving doctors’ knowledge of generic medicines.

Perspectives of physicians practicing in low and middle income countries towards generic medicines: a narrative review

OBJECTIVES

This review was conducted to document published literature related to physicians' knowledge, attitudes, and perceptions of generic medicines in low- and middle-income countries (LMICs) and to compare the findings with high-income countries.

METHODS

A systematic search of articles published in peer-reviewed journals from January 2001 to February 2013 was performed. The search comprised nine electronic databases. The search strategy involved using Boolean operators for combinations of the following terms: generic medicines, generic medications, generic drugs, generic, generic substitution, generic prescribing, international non-proprietary, prescribers, doctors, general practitioners, physicians, and specialists.

RESULTS

Sixteen articles were included in this review. The majority (n=11) were from high income countries and five from LMICs. The main difference between high income countries and LMICs is that physicians from high income countries generally have positive views whereas those from LMICs tend to have mixed views regarding generic medicines. Few similarities were identified among different country income groups namely low level of physicians' knowledge of the basis of bioequivalence testing, cost of generic medicines as an encouraging factor for generic medicine prescribing, physicians' concerns towards safety and quality of generic medicines and effect of pharmaceutical sales representative on generic medicine prescribing.

CONCLUSION

The present literature review revealed that physicians from LMICs tend to have mixed views regarding generic medicines. This may be due to differences in the health care system and pharmaceutical funding system, medicine policies, the level of educational interventions, and drug information sources in countries of different income levels.

Physicians' perception of generic and electronic prescribing: A descriptive study from Jordan

Objectives

The aim of this study was to investigate Jordanian physicians’ perception and attitudes toward generic medicines and generic substitution. It also aimed to examine factors that affect physicians’ pattern of prescribing, and to evaluate their opinion regarding future introduction of Electronic Prescribing (EP) in Jordan.

Methods

A cross-sectional descriptive study involving Jordanian physicians working in both public and private sectors was undertaken, using a self-administrated anonymous questionnaire. Frequency tables, cross-tabulation and chi square tests were used for data analysis. The response rate was 75.2% (n = 376/500).

Results

Cost was claimed to be an important factor in the prescribing decision for 69.1% of the Jordanian physicians. The majority of physicians (77.4%) claimed that they often prescribe generic medicines. Jordanian physicians predominantly welcomed the implementation of an EP and International Nonproprietary Name (INN) prescribing systems with 92%, and 80.1% respectively. More than two thirds of the physicians (69.4%) accepted generic substitution by pharmacists, with a significant association with their employment sector; physicians who work in the private sector tended to oppose generic substitution compared with physicians who work in the public sector. Physicians mostly (72.1%) opposed that generic substitution should only be allowed upon patient request.

Conclusions

Jordanian physicians have a positive attitude towards generic medications and high willingness and acceptance of strategies that encourage generic utilisation such as EP, INN prescribing and generic substitution. All these strategies would help reduce the high expenditure on medicines in Jordan. These findings would provide baseline data to policy makers to develop a robust generic policy to achieve greater clinical effectiveness and economic efficiency from medicines prescribing.

Greece's health crisis: from austerity to denialism

Greece's economic crisis has deepened since it was bailed out by the international community in 2010. The country underwent the sixth consecutive year of economic contraction in 2013, with its economy shrinking by 20% between 2008 and 2012, and anaemic or no growth projected for 2014. Unemployment has more than tripled, from 7·7% in 2008 to 24·3% in 2012, and long-term unemployment reached 14·4%. We review the background to the crisis, assess how austerity measures have affected the health of the Greek population and their access to public health services, and examine the political response to the mounting evidence of a Greek public health tragedy.

Effects of hospital generic drug substitution on diabetes therapy

OBJECTIVES

To evaluate the effects on physicians' prescribing behavior and on the therapeutic outcome of non-insulin-dependent diabetes patients of substituting different generic brands of metformin.

METHODS

We adopt a retrospective cohort study involving 280 type-2 diabetes patients who regularly used the outpatient services of one medical center and who had changed metformin brands five times between 2003 and 2008. The aim was to examine the effects of switching brands. The generalized estimating equation was used to determine whether drug brand switching affected patient glycated hemoglobin A1c (HbA1c) levels, their prescribed daily dose, or their adherence to medication with metformin.

RESULTS

HbA1c levels increased from 7.91 to 8.34 throughout the study period, although it was found that brand switching did not adversely affect HbA1c levels after controlling for patient characteristics and the time course of the study. Furthermore, the prescribed daily dose of metformin was stable throughout the study period, and was approximately 0.8 of the defined daily dose. Finally, although adherence was significantly higher with the original metformin than with the four generic brands, patients still maintained high levels of adherence of >0.8.

CONCLUSION

Although switching between different brands of metformin slightly affected the prescribing behavior of the physicians, there was no unfavorable effect on patient HbA1c levels. Thus, the policy of substituting between different generic brands of metformin is a good cost-effective approach that does not adversely affect the quality of diabetes patient care.

Assessment of antibiotic prescribing at different hospitals and primary health care facilities

In this study, it was aimed to investigate the utilization of antibiotics at various health care facilities. Photocopies of 1250 prescriptions which were containing antibiotics and written out in primary health care facilities (PHCFs), public hospitals (PHs), private hospitals and university hospitals in 10 provinces across Turkey, were evaluated by some drug use indicators. The number of drugs per prescription was 3.23 ± 0.92 and it was highest in PHCFs (3.34 ± 0.84), (p < 0.05). The cost per prescription was 33.3 $, being highest in PHs while being lowest in PHCFs (38.6 $ and 28.2 $ respectively). Antibiotic cost per prescription was 16.7 $ and it was also highest and lowest in PHs and PHCFs respectively (p < 0.05). The most commonly prescribed group of antibiotics was "beta-lactam antibacterials, penicillins" (29.2%) while amoxicillin/clavulanic acid was the most commonly prescribed antibiotic (18.1%). Sixty-one percent of the antibiotics prescribed for acute infections was generics; among facilities being highest in PHCFs (66.5%) and among diagnosis being highest in acute pharyngitis. In general, the duration of antibiotic therapy was approximately 7 days for acute infections. Although much more drugs were prescribed in PHCFs than others, it was found to be in an inverse proportion with both the total cost of prescriptions and the cost of antibiotics. Broad-spectrum antibiotics, beta-lactamase combinations in particular, were considered to be more preferable in all health care facilities is also notable. These results do serve as a guide to achieve the rational use of antibiotics on the basis of health care facilities and indications.

Reforms in the Greek pharmaceutical market during the financial crisis

INTRODUCTION

Following the financial crisis of 2008, Greece has been facing severe fiscal problems associated with high public debt and deficit. Given their significant contribution to public sector expenditure, part of the effort to reduce public expenditure has involved a focus on pharmaceutical markets.

METHODS

Our aim is to provide an overview of recent policy changes in the Greek pharmaceutical market as a response to the crisis. We also discuss other potential measures that can be implemented. The recommendations are relevant to European countries facing debt crises, but also to any other country, as improving efficiency makes funds available to be used on other interventions.

RESULTS

In 2010 and 2011, following the debt crisis and the agreement with the IMF, EU and ECB, the Greek government introduced several policy measures aimed at cost-containment. These changes included (a) price cuts, (b) the re-introduction of a positive list, (c) changes in the profit margins of pharmacies and wholesalers, and (d) tenders for hospital drugs. As a result, public drug expenditure decreased from €5.09 billion in 2009 to €4.25 billion in 2010 and €4.10 billion in 2011.

CONCLUSION

As the need to cut expenditure becomes more urgent, seeking efficiency is possibly the only option for countries that do not wish to compromise quality of healthcare and public health. However, efficiency and cost containment are not only about introducing new policies, but also about the enforcement of existing laws and fighting corruption.

Perceptions and patterns of use of generic drugs among Italian family pediatricians: first round results of a web survey

Prescription of generic medicines represents an efficacious healthcare cost containment strategy. In some European countries and in the US, generic medicines are largely prescribed. In Italy, generic drugs prescription rate is lower. General Practitioners and Family Pediatricians may be less confident in prescribing generic equivalents instead of "branded" medicines. There are currently no data about Italian Family Pediatricians' perceptions and patterns of use of generic drugs. This is a first nationwide web survey conducted with the aim to evaluate generic medicines knowledge and prescribing habits of Italian Family Pediatricians. 303 Family Pediatricians completed the online questionnaire. 37.2% and 32.6% of them declared to have a sufficient or fairly good knowledge of generic medicines, respectively, and the majority of them believed that efficacy of generic medicines was sufficient (33.6%) or good (45.2%). Nevertheless, Italian Family Pediatricians are still prone to prescribe trade medicines more frequently, since only 13.5% of them declared that more than a half of their patients were treated with generic medicines. Major issues related with generic medicines prescriptions by Italian Family Pediatricians seem to be represented by diffuse scepticism about reliability of bioequivalence tests and safety of switchability from branded to generic equivalents. More information about generic drugs and more research in the field of pediatric pharmacology are needed for increasing generic medicines prescription rate among Italian Family Pediatricians.

Physician perceptions about generic drugs

BACKGROUND

With constrained health-care resources, there is a need to understand barriers to cost-effective medication use.

OBJECTIVE

To study physician perceptions about generic medications.

METHODS

Physicians used 5-point Likert scales to report perceptions about cost-related medication nonadherence, the efficacy and quality of generic medications, preferences for generic use, and the implications of dispensing medication samples. Descriptive statistics were used to assess physician perceptions and logistic regression models were used to evaluate predictors of physician perceptions.

RESULTS

Among the invited sample, 839 (30.4%) responded and 506 (18.3%) were eligible and included in the final study population. Over 23% of physicians surveyed expressed negative perceptions about efficacy of generic drugs, almost 50% reported negative perceptions about quality of generic medications, and more than one quarter do not prefer to use generics as first-line medications for themselves or for their family. Physicians over the age of 55 years were 3.3 times more likely to report negative perceptions about generic quality, 5.8 times more likely to report that they would not use generics themselves, and 7.5 times more likely to state that they would not recommend generics for family members (p < 0.05 for all). Physicians reported that pharmaceutical company representatives are the most common (75%) source of information about market entry of a generic medication. Almost half of the respondents expressed concern that free samples may adversely affect subsequent affordability, yet two thirds of respondents provide free samples.

CONCLUSIONS

A meaningful proportion of physicians expressed negative perceptions about generic medications, representing a potential barrier to generic use. Payors and policymakers trying to encourage generic use may consider educational campaigns targeting older physicians.

Use of Generics-A Critical Cost Containment Measure for All Healthcare Professionals in Europe?

Pharmaceutical expenditures in ambulatory care rose rapidly in Europe in the 1990s and early 2000s. This was typically faster than other components of healthcare spending, leading to reforms to moderate future growth. A number of these centered on generic medicines with measures to lower reimbursed prices as well as enhance their prescribing and dispensing. The principal objective of this paper is to review additional measures that some European countries can adopt to further reduce reimbursed prices for generics. Secondly, potential approaches to address concerns with generics when they arise to maximize savings. Measures to enhance the prescribing of generics will also briefly be discussed. A narrative review of the extensive number of publications and associated references from the co-authors was conducted supplemented with known internal or web-based articles. In addition, health authority and health insurance databases, principally from 2001 to 2007, were analyzed to assess the impact of the various measures on price reductions for generic omeprazole and generic simvastatin vs. pre-patent loss prices, as well as overall efficiency in Proton Pump Inhibitor (PPI) and statin prescribing. The various initiatives generally resulted in considerable lowering of the prices of generics as well as specifically for generic omeprazole and generic simvastatin vs. pre-patent loss prices. At one stage in the UK, generic simvastatin was just 2% of the originator price. These measures also led to increased efficiency for PPI and statin prescribing with reimbursed expenditure for the PPIs and statins either falling or increasing at appreciably lower rates than increases in utilization. A number of strategies have also been introduced to address patient and physician concerns with generics to maximize savings. In conclusion, whilst recent reforms have been successful, European countries must continue learning from each other to fund increased volumes and new innovative drugs as resource pressures grow. Policies regarding generics and their subsequent impact on reimbursement and utilization of single sourced products will continue to play a key role to release valuable resources. However, there must continue to be strategies to address concerns with generics when they exist.
