Resumen

SERRA, Jesús Alberto et al. Therapeutic variability in infants admitted to Latin-American pediatric intensive units due to acute bronchiolitis. Rev. chil. pediatr. [online]. 2020, vol.91, n.2, pp.216-225. ISSN 0370-4106.  http://dx.doi.org/10.32641/rchped.v91i2.1156.

The objective of this study was to describe the management of infants with acute bronchiolitis admit ted to 20 pediatric intensive care units (PICU) members of LARed in 5 Latin American countries.

Pa tients and Method:

Retrospective, multicenter, observational study of data from the Latin American Registry of Acute Pediatric Respiratory Failure. We included children under 2 years of age admitted to the PICU due to community-based acute bronchiolitis between May and September 2017. Demo graphic and clinical data, respiratory support, therapies used, and clinical results were collected. A subgroup analysis was carried out according to geographical location (Atlantic v/s Pacific), type of insurance (Public v/s Private), and Academic v/s non-Academic centers.

Results:

1,155 patients were included in the registry which present acute respiratory failure and 6 were excluded due to the lack of information in their record form. Out of the 1,147 patients, 908 were under 2 years of age, and out of those, 467 (51.4%) were diagnosed with acute bronchiolitis, which was the main cause of admission to the PICU due to acute respiratory failure. The demographic and severity characteristics among the centers were similar. The most frequent maximum ventilatory support was the high-flow nasal can nula (47%), followed by non-invasive ventilation (26%) and invasive mechanical ventilation (17%), with a wide coefficient of variation (CV) between centers. There was a great dispersion in the use of treatments, where the use of bronchodilators, antibiotics, and corticosteroids, representing a CV up to 400%. There were significant differences in subgroup analysis regarding respiratory support and treatments used. One patient of this cohort passed away.

Conclusion:

we detected wide variability in respiratory support and treatments among Latin American PICUs. This variability was not explained by demographic or clinical differences. The heterogeneity of treatments should encourage collabora tive initiatives to reduce the gap between scientific evidence and practice.
