[Adverse drug reactions in neonates hospitalized in neonatal intensive care units in Barranquilla, Colombia].

INTRODUCTION

The appearance of adverse drug reactions in neonates is an important issue due to the lack of drug safety data.

OBJECTIVE

To identify the behavior of adverse drug reactions (ADR) in hospitalized neonates at two intensive care units in Barranquilla, Colombia.

MATERIALS AND METHODS

We conducted a cross-sectional prospective descriptive study based on patientcentered intensive pharmacosurveillance. We followed up and monitored the appearance of ADRs for six months. We used Naranjo's algorithm to assess causality, modified Hartwig and Siegel assessment scale to establish severity and Schumock and Thornton criteria to determine ADR preventability.

RESULTS

We detected 123 adverse drug reactions in 78 neonates of the 284 monitored. The cumulative incidence of ADRs was 27.4% (78/284); incidence density was 30.60 ADRs per 1,000 patients/day (78/2,549). The most affected organ system was the digestive (33.6%). Systemic anti-infective drugs were the most involved pharmacological group. Most of the ADRs were mild (58.5%), 83% were classified as probable, 16.2% as possible and 0.8% as definite.

CONCLUSIONS

ADR incidence was high in newborns, and it increased in preterm infants (less than 38 weeks of age).
