Objective. The objective of this study was to examine the association between continuity of care (COC) and emergency department (ED) utilization during infancy, when the bonds between a provider and a family are first forming and health care utilization is at it highest levels.

Methods. A retrospective birth cohort was conducted of children who were born between December 1, 1999, and April 30, 2000; health care use during the first 25 months of life was analyzed. A COC score was calculated from well-child visits in the first 7 months of life. Subsequent ED utilization, for both a 12-month and an 18-month period, was evaluated through 2 measures: 1) ED reliance (the fraction of all visits that occurred in the ED) and 2) number of ED visits. Spearman rank correlation coefficients (r_s) between COC and ED utilization were calculated. Partial rank correlations were calculated controlling for Medicaid status, income, gender, and the total number of health care visits.

Results. A total of 181 children were included in the study; 96 (53%) were male, and 48 (27%) were covered by Medicaid. COC scores ranged from 0 to 1, with a median of 1. COC scores were negatively correlated with both ED reliance (r_s = –.214) and number of ED visits (r_s = –.215) with 12 months of follow-up. The negative correlation was even stronger at 18 months of follow-up (ED reliance: r_s = –.247; number of ED visits: r_s = –.242), and this relationship remained significant with partial rank correlations.

Conclusions. Improved COC in infancy is associated with a decrease in subsequent ED utilization. Interventions aimed at increasing the continuity of early well-child visits may decrease ED utilization.
