The goal of the MGH pediatric inpatient rotation is to develop the ability of residents to evaluate and manage patients with a broad range of medical problems and make decisions about need for hospitalization, changes in status necessitating intensive care, and readiness for discharge. The rotation is based on a general pediatric ward in a tertiary care setting with patients aged birth to 21, and exposes residents to complex, referral-based medical problems. Learning will occur in a multidisciplinary team-based system. First year residents will be the primary caregivers for their patients, under the close supervision of third year residents, who will serve as team leaders. Residents will benefit from guidance by admitting pediatric and subspecialty attendings, as well as the service attending who will round with the team on a regular basis.
