Children with medical complexity (CMC) have chronic conditions, intense healthcare needs, and high healthcare utilization. Proposed changes in the healthcare environment initiated by the Affordable Care Act have led to efforts toward preventing hospital readmissions. The purpose of this integrative review is to explore the current empirical literature and examine how hospital readmissions and repeat emergency department visits have been studied among CMC. A computer database search and ancestry search were conducted, resulting in a sample of 26 studies. The results of the integrative review are presented along with gaps in the literature and implications for nursing practice and research.
