Purpose
To identify characteristics that predict successful telephone follow-up with parents of infants with severe bronchiolitis.
Methods
We analyzed data from a 17-center, prospective cohort study of infants (age <1 year) hospitalized with bronchiolitis during three consecutive fall/winter seasons. Participant contact information and clinical data were collected during the index hospitalization. Parents were called at 6-month intervals (based on the child’s age) after discharge to assess respiratory problems. The primary outcome was age 12-month telephone interview status. Participants were classified as unreachable after 28 days of unsuccessful attempts.
Results
798 of 916 children (87%) completed the age 12-month telephone interview. In unadjusted analyses, factors associated with successful follow-up included: private health insurance, annual household income ≥$60,000, and residing in the Northeast, Midwest, or West. Follow-up was less common among non-Hispanic blacks, Hispanics, and households with ≥3 children. In multivariable analyses, follow-up was more likely among parents of females, and, compared to the South, in the Northeast and Midwest (all P<0.05). Compared to non-Hispanic whites, non-Hispanic blacks and Hispanics remained less likely to complete the interview as did households with ≥3 children (all P<0.05).
Conclusion
Socio-demographic and geographic factors predict successful telephone follow-up, even among parents of infants with severe illness.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
