Abstract
The objective of this study is to investigate in infants submitted to videofluoroscopic swallowing study (VFSS) during the first year of life, the association between aspiration and later tube feeding, and to identify potential risk factors related to feeding route outcome. Retrospective cohort study with data from electronic health records was performed. Data were collected from infants < 12 months of age who underwent VFSS during inpatient hospital stay in the period between 2013 and 2018. Patient charts after 24 months of age were reviewed to ascertain the outcome and study factors, including VFSS findings, neonatal data, clinical comorbidities, nutritional status, ICU admissions, and hospital readmissions. Relative risk (RR) for tube feeding was calculated, and a Poisson regression with robust variance was used to identify potential risk factors. VFSS data from 164 patients < 1 year old were retrieved, of whom 112 (68%) contributed with data about feeding route after 2 years of age. Most infants were preterm < 37 weeks (66%), with a median age of 9.28 weeks at the time of the exam. Aspiration occurred in 33% of the patients, with no statistically significant difference between full-term or premature infants (p = 0.173). The relative risk of tube feeding after the age of 2 among infants who aspirated in VFSS was 0.74 (CI 0.25–2.16, p = 0.573). Poisson regression analysis showed that number of hospital readmissions (RR 1.04, 95%CI 1.01–1.07, p = 0.005) and gestational age < 34 weeks (RR 0.26, 95%CI 0.07–0.089, p = 0.032) were associated with later tube feeding. Early VFSS findings have low predictive value regarding later feeding route. Aspiration events should be considered as complementary information for clinical decision.
