The objective of the study was to estimate the time effect and the individual characteristics in the occurrence of an adverse event to drugs in patients with cardiac diseases. It is an evaluative study about the occurrence of an adverse event to drugs that took place at a public and cardiologic hospital, located in the city of Rio de Janeiro. For the analysis of the survival, the method Kaplan-Meier was used. The probability of surviving free from an adverse event to drugs up to 30, 60 and 100 days was respectively of 96%, 93% and 73%. The adverse events to drugs represent marking conditions that describe the performance of the health services. The detection of adverse events in hospitals makes it possible to know the failures that occur in the medication system and also to implement strategies to reduce them.
