Precision Child Health: an Emerging Paradigm for Paediatric Quality and Safety

PURPOSE OF REVIEW: Precision child health (PCH) is an emerging branch of precision medicine that focuses on the unique needs of the paediatric population. A PCH approach has the potential to enhance both quality of care and patient safety. Genome-wide sequencing can be used as a specific exemplar to showcase current opportunities and forecast future developments. RECENT FINDINGS: Information gained from genome-wide sequencing can increase awareness of common and rare medical complications. Care provided to children and their families may then shift from reactive to proactive. Pertinent categories of results from genetic testing include primary diagnostic findings, genetic modifiers of disease expression, and secondary findings. In addition, an individual’s unifying genetic diagnosis, disease subtype, and pharmacogenomic profile can all inform drug selection and treatment outcome. Recent lessons learned from the integration of genome-wide sequencing into the clinic may be generalizable to other “big data”-driven interventions. SUMMARY: Quality of care and patient safety are key targets of a PCH approach. The genomic revolution offers insights into this proposed new paradigm for healthcare delivery by showcasing the value of accurate diagnosis, disease subtyping with molecular markers, and awareness of individual- or family-specific risk factors for adverse outcomes.
