244 Chapter 8 UNRESOLVED PROBLEMS 4. What is ‘a good’ outcome? UNRESOLVED PROBLEMS 5. It is unknown how children function on different outcome domains in adulthood after undergoing OHCA at childhood. UNRESOLVED PROBLEMS 6. No international long-term follow-up guidelines exist for pediatric OHCA survivors. Unresolved problem 4. Potential solution 4. Outcome 4a.Outcome of child For research purposes, it would be desirable to define a poor or good outcome not only based on PCPC, but take into account other domains of outcome as well. The International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) of the World Health Organization is widely used in outcome research as a structured framework to describe the complex interaction between the health problem and its consequences (74) (Figure 1). This classification could be used in future studies on outcome in pediatric OHCA survivors. In 2021, a pediatric core outcome set for CA in children (P-COSCA) was developed by international multidisciplinary health care providers and parents/caregivers, with the purpose to avoid inconsistencies in outcome research (75). A core set of five outcomes was identified: survival, brain function, cognitive function, physical function, and basic daily life skills at different time points post-CA (table 1). The P-COSCA does not fully cover the ICF-CY.
