AimChildren with medical complexity require multiple providers and services to keep them well and at home. A care map is a patient/family‐created diagram that pictorially maps out this complex web of services. This study explored what care maps mean for families and healthcare providers to inform potential for clinical use.MethodParents (n=15) created care maps (hand drawn n=10 and computer‐generated n=5) and participated in semi‐structured interviews about the process of developing care maps and their perceived impact. Healthcare providers (n=30) reviewed the parent‐created care maps and participated in semi‐structured interviews. Data were analysed for themes and emerging theory using a grounded theory analytical approach.ResultsData analysis revealed 13 overarching themes that were further categorized into three domains: features (characteristics of care maps), functions (what care maps do), and emerging outcomes (benefits of care map use). These domains further informed a definition and a theoretical model of how care maps work.InterpretationOur findings suggest that care maps may be a way of supporting patient‐ and family‐centred care by graphically identifying and integrating experiences of the family as well as priorities for moving forward.What this paper adds Care maps were endorsed as a useful tool by families and providers. They help healthcare providers better understand parental priorities for care. Parents can create care maps to demonstrate the complex burden of care. They are a unique visual way to incorporate narrative medicine into practice.
