Abstract
BACKGROUND: Improved standards of perinatal care for preterm infants led to decreased hospital mortality rates during the past decade. However, studies investigating changes in drug utilisation in neonatal intensive care units (NICU) during this period are missing. OBJECTIVE: The aim of the present study therefore was to evaluate the most frequently used groups of drugs in preterm infants treated in NICUs and to analyse potential changes in drug utilisation over a period of ten years. METHODS: Drug utilisation patterns in 164 preterm infants born between 1989 and 1990 (group I; gestational age 27.2+/-1.2 weeks, birth weight 970+/-145 g) were compared to those in 113 preterm infants born between 2001 and 2004 (group II; gestational age 26.9+/-1.65 weeks, birth weight 930+/-253 g, mean and standard deviation each) with need for postnatal mechanical ventilation. RESULTS: Significant changes in drug utilisation patterns were observed for complete courses of antenatal corticosteroids (40 vs. 51.5%), diuretics (78 vs. 36.6%), surfactant (63.3 vs. 75%), methylxanthines (89.9 vs. 56.7%), sedatives/analgesics (82.4 vs. 91.5%) and catecholamines (38.3 vs. 52.4%) (group II vs. group I each). Postnatal corticosteroids were applied more often in group II (17.4 vs. 13.4%). However, duration of postnatal corticosteroid treatment has decreased (6 d vs. 13 d). The use of antibiotics remained unchanged (100 vs. 98.9%). Comparison of clinical outcome variables showed a decreased duration of mechanical ventilation and a significantly increased survival rate. CONCLUSION: Drug utilisation patterns in preterms have changed considerably during the past decade. Improved standards of care and shorter duration of mechanical ventilation may be operative.
