Two prominent infant/toddler service systems, home visiting and pediatric primary care, share in their goals to provide culturally responsive, family-centered, coordinated care in order to promote health and development. However, guiding empirical literature on fostering care coordination for infants and toddlers is limited. One potential solution is the implementation of interagency training, whereby professionals from both agencies engage in joint training experiences aimed at developing consistent communication between agencies and a clearer understanding of each system’s roles in the care of infants and toddlers. As such, the proposed project seeks to implement a collaborative interagency training for home visitors and pediatric residents that focuses on 1) agency-specific information regarding the mission, goals, infrastructure, roles and responsibilities of staff, and procedural information for collaboration efforts; and 2) culturally responsive family-centered care practices. The interagency training, Linking for Little Ones, will be developed using community based participatory research methods (Israel et al., 2005) in partnership with two home visiting and two pediatric residency training programs. Linking for Little Ones comprises five components: 1) a collaborative joint training session; 2) a home visiting case conference with pediatric residents; 3) a well-baby visit with a home visitor; 4) a home visit with a pediatric resident; and 5) a collaborative reflection session. Each component brings together home visitors and pediatric residents in interactive activities. Linking for Little Ones will be repeatedly implemented with small groups of home visitors and pediatric residents as part of naturally occurring training opportunities embedded within community health rotations in the pediatric residency training programs.
