[Systematization of interviews with altruistic blood donors during mobile campaign].

Background: The mobile campaigns of altruistic blood donation are one of the main actions of the Blood Bank of the Hospital de Especialidades "Dr. Bernardo Sepúlveda Gutiérrez". With the arrival of the new normal, after the COVID-19 pandemic, it was necessary to reactivate these actions according to the population's characteristics.

Objective: To identify socio-cultural characteristics that enhance or limit voluntary or altruistic blood donation.

Material and methods: Qualitative exploratory research, through a semi-structured interview with stratified sampling, universe of partial population of those attending blood donation; only altruistic donors were considered randomly, and representative proportions of the population subgroup were determined.

Results: Most of the donors interviewed were preliminary donors who approached the blood donation tent without focused promotion. Health professionals showed greater identification to altruistic blood donation. Donors declared a lack of donation culture as the main factor limiting this human activity. Finally, they considered the accessibility to the blood donation tent as determinant for altruistic blood donation.

Conclusions: Twelve recommendations were established to the Blood Bank, with which the intention is to propose strategies and establish research channels that increase the impact on the promotion of altruistic blood donation in future campaigns.
