Models and theories of prescribing decisions: A review and suggested a new model

Abstract

To date, research on the prescribing decisions of physician lacks sound theoretical foundations. In fact, drug prescribing by doctors is a complex phenomenon influenced by various factors. Most of the existing studies in the area of drug prescription explain the process of decision-making by physicians via the exploratory approach rather than theoretical. Therefore, this review is an attempt to suggest a value conceptual model that explains the theoretical linkages existing between marketing efforts, patient and pharmacist and physician decision to prescribe the drugs. The paper follows an inclusive review approach and applies the previous theoretical models of prescribing behaviour to identify the relational factors. More specifically, the report identifies and uses several valuable perspectives such as the ‘persuasion theory - elaboration likelihood model’, the stimuli–response marketing model’, the ‘agency theory’, the theory of planned behaviour,’ and ‘social power theory,’ in developing an innovative conceptual paradigm. Based on the combination of existing methods and previous models, this paper suggests a new conceptual model of the physician decision-making process. This unique model has the potential for use in further research.

A survey of nurse practitioner controlled drugs and substances prescribing in three Canadian provinces

“…Provider experience (Wright & Neill, ), site of practice and specialty area (Knapp & Oeljen, ) and patient characteristics (Abbo et al, ; Knight, ) have been recognised as important contributors to prescribing decisions. Conceptually, provider habit persistence and patient request for drug and expectations have also been identified as influential factors to physician prescribing (Murshid & Mohaidin, ). It is unclear if this is the case in the current study.…”

“…The most recently proposed model for physician prescribing behaviour was developed and tested by Murshid and Mohaidin (). Their model incorporates variables derived from Social Power Theory, Agency Theory, Persuasion Theory, Theory of Planned Behaviour, and Stimulus‐Response Theory, all theories previously considered to be influential to the process of physician prescribing.…”

“…Nurse practitioners and physician prescribing behaviours have been the topic of many scholarly articles (Gallan, 2004;Kyle, Nissen, & Tett, 2008;Murshid & Mohaidin, 2017;Raisch, 1990;Stros & Lee, 2015).…”

“…Given that no studies on CDS prescribing have yet been completed, this review was limited to prescribing practices of other classes of medication, such as antibiotics. Several factors have been found to influence physician prescribing, these factors include marketing efforts (Gallan, 2004;Kyle et al, 2008;Raisch, 1990;Stros & Lee, 2015), patient characteristics (Raisch, 1990), pharmacist factors (Murshid & Mohaidin, 2017) and contextual factors, that is cost/benefit ratio of drug, or drug characteristics (Singh, 2008;Stros & Lee, 2015).…”

“…Nurse practitioners and physician prescribing behaviours have been the topic of many scholarly articles (Gallan, ; Kyle, Nissen, & Tett, ; Murshid & Mohaidin, ; Raisch, ; Stros & Lee, ). Previous work in this area focused on factors influencing general prescribing and more specifically the topic of antimicrobial prescribing.…”
