Waiting rooms in general practitioners' GP surgeries are a potentially useful site for spreading educational messages about health behaviors. We aimed to evaluate the impact of posters displayed in GPs' waiting rooms on the number of donors attending the blood donation drives in the Aube Department of France.
The secondary objective was to identify self-reported factors that incited people to give blood among donors who did and donors who did not see the posters. Observational, multicenter, prospective study, from 1 June to 31 December Six blood donation centers in the Aube Department were selected. All GPs located within a 15 km radius around each center were invited to participate by hanging posters advertising blood drives in their waiting rooms.
The number of blood donations per hour was measured before and during the campaign. Factors prompting people to give blood were evaluated by questionnaires completed by persons attending the blood drives.
The number of donations per hour was lower in the year in which the posters were displayed compared to the previous year 12 vs. A total of 1, questionnaires were completed by blood donors: reported having seen the posters, and reported not having seen the posters. Those who claimed to have seen the posters were more likely than those who claimed not to have seen the posters to respond that in parallel, they had been prompted to give blood via online publicity 7.
