Explanatory model of prescribing behavior in prescription of statins in family practice

Abstract

The determinants that influence statin prescribing behavior among GPs in our study covered an array of explanatory items consistent with proposals in the literature but factors differ to some extent from proposed theoretical models. The explanatory model explained a high proportion of the variation in deciding on a particular statin. Efficacy and safety remain important factors in selection of an appropriate drug but are far from being the most or only important factors.

Development and validation of an instrument designed to measure factors influencing physician prescribing decisions

“…The associations between the variables were found to be lower than the results of Cronbach’s alpha, indicating evidence of the discriminant validity of the measure. This finding maybe not surprising, considering previous research findings confirmed that drug requests by brand name and patient expectations are found to have a positive effect on the physician prescriptions 13,70…”

“…The results found that drug characteristics have no significant relationship with prescribing decisions. Perhaps that the characteristics of the drug make it entail diverse viewpoints of the products in the prescription of drugs 13,71. This argument corresponds to Pinto et al , who opine that elements such as side effects and cost were considered less relevant by the physicians 72.…”

“…For patient request the drug, two items were modified from Parker et al , and a single item was developed from the literature. Patient expectations were assumed by four items 13,45. The adapted items from Tahaineh et al .…”

“…Using 250 GPs, Tusek–Bunc et al . focused on four items to assess the physicians’ perceptions of patients’ expectations 13. However, content validity and reliability were not evaluated in this research.…”

Moderating effects of contextual factors on relationship between pharmaceutical marketing strategies and physician prescription decision: A review

“…Whilst physicians emphasize clinical efficacy, they seem willing to take cost under certain conditions [2]. The benefits of the drug were found to be a distinct factor influencing prescription [52]. In developing countries, the consumption of drugs is largely linked to the purchasing power of the patient [2].…”
