ABSTRACT To determine the trends in incidence of diagnosis of bronchopulmonary dysplasia (BPD) and associated health services use for the neonatal hospitalization of patients with BPD in an era of changing definitions and management.
All neonatal hospitalization records available through the Nationwide Inpatient Sample, 1993-2006, were analyzed. Multivariable regression analyses were performed for incidence of BPD diagnosis and associated hospital length of stay and charges. Multiple models were constructed to assess the roles of changes in diagnosis of very low birth weight (VLBW) neonates and different modalities of respiratory support used for treatment.
The absolute incidence of diagnosis of BPD fell 3.3% annually (P = .0009) between 1993 and 2006 coincident with a 3.5-fold increase in the use of noninvasive respiratory support in patients with BPD. When data were controlled for demographic factors, this significant decrease in incidence persisted at a rate of 4.3% annually (P = .0002). All models demonstrated a rise in hospital length of stay and financial charges for the neonatal hospitalization of patients with BPD. The incidence of BPD adjusted for frequency of prolonged mechanical ventilation also decreased but only by 2.8% annually (P = .0075).
The incidence of diagnosis of BPD decreased significantly between 1993 and 2006. In well-controlled models, birth hospitalization charges for these patients rose during the same period. Less invasive ventilatory support may improve respiratory outcomes of VLBW neonates.

    ABSTRACT: Background: In very low birth weight (VLBW) infants, obstructive bronchitis is a frequent cause of hospital re-admission. For VLBW infants, early vaccinations starting at 2 months after birth have been recommended. Objective: To analyze risk factors for bronchitis during the first year after discharge and the effects of in-hospital standard vaccination (hexavalent/pneumococci) and/or RSV immunoprophylaxis with palivizumab. Methods: A standardized questionnaire was sent to the parents of VLBW infants 7 month after discharge. The reported episodes of bronchitis were correlated with clinically recorded parameters including risk factors for pulmonary morbidity. The effects of in-hospital vaccination were assessed in a subgroup discharged after day 60. Results: A sample of 1 967 responses of infants born 2009-2011 was analyzed. Risk factors for bronchitis were male gender and older siblings. 24% of the population had episodes of bronchitis. In the subgroup discharged after day 60, episodes of bronchitis were reported for 31% of infants who were not vaccinated in-hospital. A significant reduction of the bronchitis rate was found in infants who received palivizumab±standard vaccination (17% bronchitis, p=0.003). Interestingly, in-hospital standard vaccination without RSV immunoprophylaxis was protective (20% bronchitis; p=0.037) as well. Conclusions: Non-vaccinated male VLBW infants with older siblings are at increased risk for bronchitis during the first year after discharge. Vaccination according to schedule seems to have protective effects, while underlying mechanisms are unknown. The rate of timely vaccination in preterm infants should be increased. © Georg Thieme Verlag KG Stuttgart · New York.
