[Knowledge and attitude about Pharmacovigilance practices of pharmacy professionals of community pharmacy and hospital pharmacy in Spain.]

Objective: The justification of the study was to assess the degree of knowledge of Spanish pharmacists in the field of Pharmacovigilance, their degree of notification of adverse drug reactions and their need for training, establishing the differences between community pharmacy pharmacist and those of hospital pharmacy.

Methods: A questionnaire with twelve questions on Pharmacovigilance was designed. The distribution and collection of the questionnaires were carried out via online in collaboration with the Official Colleges of Pharmacists and the Spanish Society of Hospital Pharmacy during the period from November 2018 to June 2019. The target population were the pharmacists registered or belonging to the Spanish Society of Hospital Pharmacy. The results were processed using a descriptive and analytical analysis. The qualitative variables were presented with their frequency distribution and the quantitative with their mean and standard deviation.

Results: 99% of hospital pharmacists said they had evidence of suspected adverse reactions and 96.9% of them ever reported. 73.5% of community pharmacists stated that they had knowledge of suspected adverse reactions but only 48.7% confirmed that they notified them. In general, the pharmacists surveyed agreed on the importance of Pharmacovigilance and believed that the quality of treatments could be improved and the Spanish health system would be saved if Pharmacovigilance was applied more.

Conclusions: Our results indicated that hospital pharmacists report much more adverse drug reactions than community pharmacist does. It also hospital pharmacists who know best the obligations they have with Pharmacovigilance. The surveyed pharmacists thought that the development of actions in Pharmacovigilance would increase the adherence of pharmaceutical professionals to the notification and would imply improvements in the quality of treatments, the rational use of medications and patient safety.
