Children with medical complexity (CMC) receive life-sustaining treatments such as tracheostomy. The objective of this paper is to explore the roles of religion and spirituality (RS (2) Spirituality was an important factor for caregivers in the decision to pursue tracheostomy for their children; (3) Many caregivers did not discuss their spirituality with clinicians for a variety of reasons; (4) Clergy and hospital chaplains played a major supportive role overall; however, they did not play a significant role in the decision-making process. Our study shows the importance of R&S, and the roles of clergy and chaplains in pediatric tracheostomy decision-making.
