Abstract:
Abstract Introduction The physicians are responsible for prescribing medicine rationally. Physician's awareness of prescribing guidelines can lead to the selection of the most effective, appropriate and effective measures to the improved prescription. This study aim is to determine the factors influencing drug prescribing behaviour in family physicians. Methods This cross-sectional study was conducted in 2016 on a case study including 150 family physicians from Shiraz City who were selected by systematic random sampling method. A questionnaire related to the behaviour of prescribing physicians was used based on the theory of planned behaviour to collect data. The validity of the questionnaire was confirmed by the experts' opinion and its reliability was confirmed by calculating the Cronbach's alpha. The data were analyzed using structural equation modelling (SEM) by SPSS and Smart PLS software. Results It was specified that 39.3% of Shiraz family physicians have prescribed medicines for their most patients (61-70%) during the last month. Furthermore, 60% of physicians have prescribed for about 20% of their patients without any examination. In addition, 63% of doctors have repeated prescription for about 20% of patients with chronic disease. Based on the obtained results of the Research Structural Equation Model, none of the four considered variables explains changes in physicians' behaviour regarding prescribing. Although, “mental and perceived behavioural control” explain 30.2% of the changes in the intention of prescribing medication of family physicians in Shiraz. Conclusions The family physicians' behaviour in prescribing medicine shows the impact of factors such as the patient's request, as well as the role of the patients and colleagues pressure for prescribing medicine as a quality criterion for their practice. norms of mental and perceived behavioural control are effective in explaining the purpose of prescribing. Key messages Policymakers should implement policies to develop physicians’ behavior and logical prescription by education, financial incentives; consequently. Mental and perceived behavioral control are effective in explaining the purpose of prescribing.
