PEREDO-SILVA, Luis; LIFSHITZ, Alberto; REYES-MORALES, Hortensia  and  MINO-LEON, Dolores. Physicians and the pharmaceutical industry: impact on prescription attitudes and habits. Gac. Méd. Méx [online]. 2020, vol.156, n.6, pp.556-562.  Epub May 27, 2021. ISSN 2696-1288.


The physician-pharmaceutical industry relationship has been identified as an ethical problem, due to conflicts of interest motivated by the benefits that doctors receive and that can affect their clinical judgment.


To identify the frequency of physicians participation in activities financed by the pharmaceutical industry (PI), their attitudes towards PI representatives (PIRs), their prescriptive behavior and the association between their characteristics and their workplace with their participation in activities financed by the PI.


Cross-sectional survey to internists and cardiologists. The questionnaire included characteristics of the doctors and their workplace, participation in activities financed by the PI, attitudes towards PIRs, and prescription behavior.


455 questionnaires were analyzed; 78.5 % of surveyed subjects were aware of the physician-PI relationship, the majority acknowledged meeting with PIRs, 30 % indicated having received financial subsidies and 10 % considered that gifts affect their prescription. Having prior knowledge of the physician-PI relationship was associated with less participation in PI-financed educational activities.


Practices and preferences towards the PI show the need to design strategies to avoid inappropriate prescription.
