<h3>Category/Date</h3> Research Poster presented at NAPNAP's 42<sup>nd</sup> National Conference on Pediatric Health Care, March 24<sup>th</sup>, 2021. https://napnap21.org/community/#/home <h3>Background</h3> Children born with complex life-threatening chronic conditions (CLTCs) often require highly complex care and decision-making. Previous research has documented that decisions about healthcare treatment can be intimately connected with personal perceptions and interpretations of information, communication, and parent empowerment. Parents of children born with CLTCs often experience an uncertain trajectory in which hope plays a critical, but largely unexplored, role in their decision-making. <h3>Purpose</h3> This qualitative descriptive study aimed to explore how parental and provider hope may influence decision-making and care for a child born with a CLTC. <h3>Methods</h3> This was a Duke University IRB approved study. Data collection for each case was derived from qualitative semi-structured interviews occurring at least monthly until one year after study enrollment, unless death of the child intervened. Interview questions targeted parental and provider perceptions of previous or anticipated decisions, experience caring for the infant, and how provision of care had been affected by decisions made. We utilized a subset of 193 interviews with parents and healthcare providers responsible for the care of 10 infants with complex congenital heart diseases (cases), selected from a large prospective longitudinal study on parent and provider decision-making for 35 infants with CLTCs. Enrollment of infants with complex congenital heart disease began at birth for those with a prenatal diagnosis, or otherwise at time at diagnosis. Each case consisted of an infant, at least one parent, and at least three providers (e.g. attending physician, nurse, nurse practitioner). Transcripts were uploaded to and analyzed in NVivo 12 and a codebook was defined. Generated themes illustrated the intersection of hope with the dynamics of communication, relationships, and emotions that in turn influence decision-making. <h3>Results</h3> Through our analysis, we developed a central framework of the effects of hope on decision-making through the influence of three factors: emotions, relationships, and communication. The linkages between these concepts are integral, yet fluid and nonlinear. Overall, parental hope remained strong over the course of the study, and played a pivotal role in parents' decision making despite changes in relationships with providers and other adults, fluctuating emotions, and both positive and negative perceptions of communication. Both parents and professional health care providers express a range of emotions which impact communication, that appear to be strongly linked to hope and decision-making. Additionally, relationships as well as communication between parents and provider both appeared responsible for and responsive to changes in hope which impacted parental and provider decision making for the child with CLTCs. <h3>Discussion/conclusion</h3> Multiple barriers exist to parent-provider communication, including structural (e.g. rotating providers) as well as regarding parental characteristics (e.g. education, age, medical insurance) and opinions and judgements placed on parents by providers. Parents of children with CLTCs benefit from emotional and practical support, trusting relationships with providers, agency in and information about their child's care. To support these needs, it is crucial that healthcare providers receive training to become comfortable having difficult, trusting, and honest conversations with parents and be mindful of parents' own needs and responsibilities.
