ObjectiveTo identify patient factors and medications associated with the occurrence of drug-related problems (DRPs) in neonates admitted to neonatal intensive care units (NICUs).DesignProspective, longitudinal study.SettingNICU of a teaching hospital in Brazil.ParticipantsData were collected from the records of the clinical pharmacy service of all neonates admitted between April 2014 and January 2017, excluding neonates with length of stay in the NICU <24 hours or without prescribed drugs.Primary outcome measuresOccurrence of one or more DRP (conditions interfering in the patient’s pharmacotherapy with potential undesired clinical outcomes).ResultsThe study observed 600 neonates who had a median length of stay in the NICU of 13 days (range 2–278 days). DRPs were identified in most neonates (60.5%). In a multivariate logistic regression model, the factors independently associated with DRP were gestational age (adjusted OR (AOR) 0.85, 95% CI 0.81 to 0.89), 5 min Apgar <7 (AOR 1.74, 95% CI 1.00 to 3.13), neurological disease (AOR 2.49, 95% CI 1.09 to 5.69), renal disease (AOR 5.75, 95% CI 1.85 to 17.8) and cardiac disease (AOR 2.36, 95% CI 1.31 to 4.24). The medications with greater risk for DRP were amphotericin B (AOR 4.80), meropenem (AOR 4.09), alprostadil (AOR 3.38), vancomycin (AOR 3.34), ciprofloxacin (AOR 3.03), gentamicin (AOR 2.43), cefepime (AOR 1.88), amikacin (AOR 1.82) and omeprazole (AOR 1.66). These medicines represented one-third of all prescribed drugs.ConclusionsGestational age, 5 min Apgar <7, and neurological, cardiac and renal diseases are risk factors for DRP in NICUs. Alprostadil, omeprazole and several anti-infectives were associated with greater risk of DRP.
