Patients' intention to consume prescribed and non-prescribed medicines: A study based on the theory of planned behaviour in selected European countries.

WHAT IS KNOWN AND OBJECTIVE: Polypharmacy has a significant impact on patients' health with overall expenditure on over-the-counter (OTC) medicines representing a substantial burden in terms of cost of treatment. The aim of this study, which was conducted within the framework of a European Project funded by the European Union under the Seventh Framework Programme and was entitled OTC-SOCIOMED, was to report on possible determinants of patient behaviour regarding the consumption of medicines, and particularly OTCs, in the context of primary care. METHODS: A multicentre, cross-sectional study was designed and implemented in well-defined primary healthcare settings in Cyprus, the Czech Republic, France, Greece, Malta and Turkey. Patients completed a questionnaire constructed on the basis of the theory of planned behaviour (TPB), which was administered via face-to-face interviews. RESULTS AND DISCUSSION: The percentage of patients who had consumed prescribed medicines over a 6-month period was consistently high, ranging from 79% in the Czech Republic and 82% in Turkey to 97% in Malta and 100% in Cyprus. Reported non-prescribed medicine consumption ranged from 33% in Turkey to 92% in the Czech Republic and 97% in Cyprus. TPB behavioural antecedents explained 43% of the variability of patients' intention to consume medicines in Malta and 24% in Greece, but only 3% in Turkey. Subjective norm was a significant predictor of the intention to consume medicines in all three countries (Greece, Malta and Turkey), whereas attitude towards consumption was a significant predictor of the expectation to consume medicines, if needed. WHAT IS NEW AND CONCLUSION: This study shows that parameters such as patients' beliefs and influence from family and friends could be determining factors in explaining the high rates of medicine consumption. Factors that affect patients' behavioural intention towards medicine consumption may assist in the formulation of evidence-based policy proposals and inform initiatives and interventions aimed at increasing the appropriate use of medicines.

Eliciting general practitioners' salient beliefs towards prescribing: a qualitative study based on the Theory of Planned Behaviour in Greece.

WHAT IS KNOWN AND OBJECTIVE: Prescribing represents an important medical action especially in primary care. However, irrational prescribing is common and has an impact on clinical and economic outcomes. Therefore, there is a growing need to rationalize prescribing. Knowledge of influential factors is crucial for achieving this. The aim of the present study was to identify the behavioural, normative and control beliefs of GPs regarding prescribing in Greece. METHODS: Focus group sessions were conducted in three geographically defined areas in Greece. GPs working in the private and public sector in primary care settings were invited to participate. Transcripts from focus groups were content analysed using the Theory of Planned Behaviour (TPB) as the theoretical framework. RESULTS AND DISCUSSION: GPs acknowledged prescribing as the most important method for treating diseases in primary health care, with significant impact on patient's health and quality of life. The expectations of patients and their families were extremely influential during prescribing. Pharmaceutical sales representatives, other GPs and specialists, as well as public health authorities influenced prescribing. GPs admitted that factors such as the income of the patient, the limited time available and special situations such as prescribing through a third person or prescribing following patients' prescription requests for medicines that they have previously purchased over the counter through pharmacies may facilitate or hinder their prescribing decision. WHAT IS NEW AND CONCLUSION: This elicitation study shed light into GPs' beliefs regarding prescribing. Factors that are not common in the usual European setting were revealed, such as the influence of the patients' family and special situations during prescribing. Thus, various issues were highlighted that should inform the development of items for inclusion in a forthcoming TPB-based questionnaire. The results of this study revealed also certain issues that can affect the design of policies aiming at the rationalization of prescribing.

Generic medicines: Greek physicians' perceptions and prescribing practices.

BACKGROUND AND OBJECTIVE: The penetration of generic drugs in the Greek pharmaceutical market is placed among the weakest in the EU. The Greek regulatory framework does not systematically support the development of this subsector and physicians are not provided with incentives for prescribing generics. The aim of this study was to investigate the prescribing profile of physicians in Greece with a focus on the factors that influence their decision on generics prescribing. METHODS: A structured questionnaire was sent by mail to a random national sample of 1463 physicians, stratified by sex, specialty and geographical region. RESULTS AND DISCUSSION: The response rate was 82.3%. Greek physicians have a positive view on generics but they prefer to prescribe the original products. According to our analysis, physician's age and their opinion on generics' efficacy and effectiveness are identified as important determinants of their prescribing decision. The primary reason that could make them change their prescribing habits is the appearance of side-effects. Patients' insurance coverage and income, as well as the drug cost are also referred as factors that influence their prescribing decision. Despite the fact that they do not usually prescribe generics in their clinical practice, they are willing to substitute an original drug by a generic product. CONCLUSIONS: Our findings suggest that Greek physicians could be persuaded to prescribe generic medicines, if a generic promotion policy was introduced in the country. To develop such a policy, a set of supply side and demand-side measures should be implemented along with provision of information on generics to physicians during their education and clinical practice.
