Primary physicians’ attitudes toward their patients receiving a proposal to participate in a vaccine trial

Abstract

A trustworthy relationship between primary physicians (PPs) and their patients is crucial for vaccine acceptance. Little is known about attitudes of PPs toward participation of their patients in a preventive vaccine trial (PVT) proposed by investigation sites. A cross-sectional study was conducted in Auvergne-Rhône-Alpes region (France) including an anonymous questionnaire for general practitioners (GPs) and other specialists as well as face-to-face interviews. A scenario of a patient, with chronic medical conditions, invited to participate in a PVT and reporting this situation to his/her PP was drawn up. PPs’ attitudes were assessed in quantitative approach by a 5-point Likert scale and in qualitative approach by semi-directed individual interviews. Among the 521 respondents to the questionnaire, 429 (82.3%) were GPs and 92 (17.7%) were other specialists. Only 7.5% (39/521) of respondents regularly practice clinical research. Confronted with the scenario, 312 respondents (59.8%) declared they would give their opinion spontaneously. Before giving their opinion, PPs would like more information about the trial (91.4%, n = 476). Whatever their attitude, 488 (93.7%) would be influenced by available safety data. Face-to-face interviews confirmed that PPs lack of knowledge about clinical research, and would like to obtain information from investigators, particularly about safety. PPs seem to be concerned by the decision of their patients to participate or not in a PVT but would like more information about the trial and clinical research before giving their opinion. Getting PPs to be more involved in the enrollment of patients in PVT may improve recruitment.
