Effect of telephone calls from primary care practices on follow-up visits after pediatric emergency department visits: evidence from the Pediatric Emergency Department Links to Primary Care (PEDLPC) randomized controlled trial.

OBJECTIVE: To test whether follow-up phone calls to counsel families about pediatric emergency department (PED) use and primary care availability made after an index PED visit would modify subsequent PED use.
DESIGN: Longitudinal prospective randomized intervention.
SETTING: An urban academic children's hospital. PATIENTS: A total of 4246 individuals aged 0 to 21 years from each of 4 participating primary care practices recording an index PED visit from April through December 2005. INTERVENTION: Follow-up phone call from the primary care practice within 72 hours of the initial PED visit to counsel about the availability of after-hours advice and when to access the PED. MAIN OUTCOME MEASURES: All subsequent visits to primary care practices, PED, pediatric subspecialists, or for inpatient hospitalization during a 365-day follow-up period. Logistic and ordinary least squares regressions estimated unadjusted and adjusted odds ratios of follow-up visits, controlling for covariates.
RESULTS: Of the 2166 intervention subjects, 816 (37.7%) recorded follow-up PED visits compared with 819 (39.4%) of the 2080 control subjects (P = .26, not significant). The adjusted odds of a follow-up visit being to the PED rather than to another venue was significantly less for intervention than for control subjects (odds ratio, 0.88; confidence interval, 0.82-0.94), indicating decreased intensity of PED use.
CONCLUSION: Follow-up phone calls from primary care practices after PED visits counseling patients on the use of primary care and emergency services can modulate subsequent care-seeking behavior and decrease future PED use.
