Implementation of a Hospital Pharmacovigilance Service and Comparison of Algorithms for Adverse Drug Reaction Causality Assessment

Detailed Summary

Spontaneous reports by health professionals generate the signals in pharmacovigilance. However, the passive method has limitations and the most important of them are the underreporting and the poor quality of data, hindering the causality assessment of adverse drug events (ADE). Therefore, the present study aimed to validate an educational intervention (EI) in pharmacovigilance for hospital health professionals, in order to analyze the impact on the knowledge, skill and attitude in ADE reporting. Investigators proposed a multifaceted EI which will be developed in four meetings with one hour each. The following activities will be carried out: application of a questionnaire to assess the knowledge, skill and attitude before and after EI; lecture; practical class and education material distribution. The answers of questionnaire are going to be analyzed using content analysis technique. The definitions of World Health Organization and the minimum and desired criteria to fill the ADE form, according to the Pan American Health Organization, are going to be considered gold-standard answers. The statistical test of Wilcoxon-Mann Whitney test for paired samples will be applied, in order to assess the impact of educational intervention on behavior of health professionals (ADE reporting). With the present study, the following hypotheses will be tested: H0= There is no difference between the numbers of ADE reported (behavior/attitudes) before and after the educational intervention. H1= The numbers of ADE reported before and after the educational intervention are different.
