Abstract
INTRODUCTION
Bronchiolitis is the most common respiratory infection and reason for hospitalisation in infancy; however, outcomes of infants with bronchiolitis who require interhospital transfer by specialist medical retrieval services are poorly understood.
OBJECTIVES
The objective of this study was to summarise current evidence of the rate, therapy, and outcomes of infants with bronchiolitis who required medical retrieval for ongoing management.
REVIEW METHOD
A scoping literature review informed by the Joanna Briggs Institute methodology was used including published studies in any language covering the period 1996 to December 2022 and grey literature sources comprised of reports from retrieval services in high-income countries with comparable healthcare systems.
DATA SOURCES
Medline, CINAHL, and the Cochrane Database of Systematic Reviews electronic databases were the sources for published studies. Grey literature sources were retrieval service web pages/social media sites from Australia, Canada, New Zealand, the United Kingdom, and the United States of America.
RESULTS
Searching identified 12 677 records, with 12 069 ineligible records and 286 duplicates excluded at screening. Of the 72 papers included for title and abstract review, 16 were selected for full-text review. Six papers fulfilled inclusion criteria. Infants with bronchiolitis were the primary focus of three studies. Transfer rate was reported in four studies, ranging from 4.3% to 18.5%. Use of respiratory therapy was variably reported and was associated with prematurity. Outcomes following retrieval such as respiratory therapies, days on therapies, length of stay in the intensive care unit, and hospital length of stay were only reported in two studies. Of 103 identified medical retrieval services and data registries, no reports were found that included information on the number of transfers or outcomes for infants with bronchiolitis.
CONCLUSIONS
Up to one in five infants with bronchiolitis require medical retrieval. Only two published studies and no reports reported on the number and outcomes of infants. Given the frequency and severity of bronchiolitis, understanding indications for medical retrieval and outcomes of those infants may help to better target care and interventions for this common illness. Benefits could include diminishing the costly burden to families and the healthcare system of avoidable medical retrieval and interhospital transfer.
