Figure 1: A proposed hybrid DTP model. The model is featured by being comprehensive in a way to combine all the factors suggested to improve physicians' attitude toward better optimization. The main weakness in the model is the absence of any type of gifts or financial supports which is used to be directed to physicians. Pharmaceutical industries support this issue very well, and consider it the cornerstone in DTP. Oppositely, ethical committees consider this a typical malpractice and can influence the way of thinking regardless the reality of the outcomes (Donohue et al., 2004) [18].
