Objectives: Follow-up compliance is critical in febrile children becau
se they may harbor unrecognized life-threatening illnesses. This study
compares follow-up rates between 2 systems: Wilford Hall Medical Cent
er (WHMC), with preset appointments after ED release, and free medical
care; and Fairfax Hospital (FFX), where parents must arrange followup
appointments after ED release, and are responsible for payment for th
eir follow-up visits. The study also investigated factors associated w
ith follow-up compliance. Methods: This was a prospective, observation
al study of febrile children seen in 2 ED's with different systems for
patient follow-up. From ED records and parental phone calls, diagnosi
s, follow-up compliance, and demographics were collected. Data were an
alyzed using logistic regression and chi(2). Results: 423 children met
entrance criteria, and 330 parents were successfully contacted after
the child's ED release (146 from WHMC; 184 from FFX). The WHMC childre
n were more likely to comply with follow-up than were the children in
the FFX system (92% vs 67% follow-up, odds ratio 2.5, 95% CI 1.1-5.3).
Other factors associated with noncompliance with recommended follow-u
p were: Hispanic ethnicity, non-English-speaking parents, and follow-u
p suggested for >24 hours after ED release. For FFX, self-pay, lack of
a follow-up physician, parents' dissatisfaction with the ED medical c
are, and diagnosis of otitis media were also significant factors found
associated with noncompliance. Conclusion: Febrile children evaluated
in a medical system with prearranged follow-up appointments and free
medical care are more likely to comply with recommended followup than
are those evaluated in a system where payment and appointments are the
responsibility of the parents. Efforts should be made to improve foll
ow-up compliance by modeling the WHMC system.
