Parents of infants with complex congenital heart disease obtain knowledge, confidence, and mastery dependent upon their transition experience and their personal journey through pre-liminal, liminal, and post-liminal phases of discharge from hospital to home. A conceptual framework "Parenting through Transitions - hospital to home" emerged that could assist in structuring assessment of parents' knowledge and support needs within a coordinated discharge process. Identifying individualized support would promote adaptation and adjustment during transition from the pre to post liminal phase, following their infant's first stage of complex cardiac surgery.
