Processes and determinants of integration of eGFR in physicians' drug prescriptions: a qualitative study of semi-structured interviews.

Residency and training, professional experience - including experiences of adverse drug reactions - and the membership in various communities of professionals were key drivers for the integration of eGFR in prescriptions. The theoretical aim was above all safe prescribing in order to reduce adverse drug reactions, with the control by a dispensing pharmacist and/or other healthcare professionals. Nevertheless, none of the physicians had received any feedback from any healthcare professionals. Despite their disappointment, the physicians remained convinced of the interest of integrating eGFR in their prescriptions and would continue to do so. Characteristics associated with integration of eGFR in drug prescriptions belong partly to Roger's theory of innovations. If a widespread diffusion of this habit takes place, it will be necessary to evaluate its adoption by both physicians and pharmacists.
