Study summary

Compare the effectiveness of automatic vs as-needed (PRN) post-hospitalization follow-up for children who are hospitalized for common infections.

Read the detailed description

BACKGROUND:

Automatic post-hospitalization follow-up visits are commonly recommended by hospital-based pediatricians. The intuitive appeal of automatic follow-up visits is that they might decrease hospital readmissions and promote continuity of care. However, automatic follow-up visits result in missed work for parents, missed school for children, and expenses like co-pays and transportation costs. The principal alternative strategy to automatic follow-up is PRN (pro re nata, "as-needed") follow-up, a patient and family-centered approach that empowers parents to monitor their child's symptoms and decide if a follow-up visit is necessary.

OBJECTIVE:

Compare the effectiveness of automatic vs as-needed (PRN) post-hospitalization follow-up for children who are hospitalized for common infections.

DESIGN:

The Follow-up Automatically vs As-Needed Comparison (FAAN-C, or "fancy") trial is a multicenter randomized controlled trial

POPULATION:

Children hospitalized for pneumonia, skin and soft tissue infection, acute gastroenteritis, or urinary tract infection will be eligible for enrollment.

EXPERIMENTAL INTERVENTION:

Randomization to a recommendation for PRN post-hospitalization follow-up

CONTROL INTERVENTION:

Randomization to a recommendation for automatic post-hospitalization follow-up

OUTCOMES:

The primary outcome is hospital readmission within 14 days of discharge. Secondary outcomes are medical interventions and child health-related quality of life. Exploratory outcomes are cost burden, child time, parent time, symptom duration, total additional ambulatory visits, non-primary care ambulatory visits, parent self-efficacy, parent anxiety, satisfaction with care, telephone and electronic communications with medical providers, well-child visits, immunizations, usual place of medical care, and medical interventions related to the index infection. Safety outcomes are medical errors and hospital readmissions related to the index infection.

TRIAL SIZE:

A total of 2,674 patients (1,337 patients in each group) will be randomized, providing 90% power to demonstrate non-inferiority of a recommendation for PRN follow-up compared to a recommendation for automatic follow-up.

Study arms

  • Experimental
    As-needed (PRN) post-hospitalization follow-up

    At hospital discharge, participant receives a recommendation for PRN follow-up. Recommendation informs participant that scheduling a follow-up visit is not needed at discharge and suggests that participant follow symptoms after discharge to decide if a visit is ultimately needed or not.

    Behavioral: As-needed follow up

  • Active comparator
    Automatic post-hospitalization follow-up

    At hospital discharge, participant receives a recommendation for automatic follow-up. Recommendation instructs participant to schedule a follow-up visit and attend the visit even if symptoms get better.

    Behavioral: Automatic follow-up
