Background Delayed recognition of clinical deterioration can result in harm to patients. Parents/carers can often recognise changes in the child’s condition before healthcare professionals (HCPs). To mitigate the risk of failure to rescue and promote early intervention, family-activated rapid response (FARR) systems are part of family-integrated care. Mechanisms for parents/carers to escalate concerns regarding their child’s clinical status remain limited to direct verbal communication, which may impede those with communication/linguistic challenges.

Aim To develop a digital multilingual intervention by which families/carers can escalate their concerns directly to the rapid response team while in acute paediatric care.

Methods A single-centre qualitative, co-design app development study was conducted. Evidence synthesis from a systematic review of the international literature informed interviews on intervention prototype development using co-design focus groups. Participant recruitment targeted underserved communities for multilingual functionality validity. Data were analysed using qualitative content analysis.

Results Thirty parents/carers (n=16) and HCPs (n=14) participated in the study. Three themes were generated from the data analysis: (1) relational considerations; communication, professional and parental attributes, and collaborative working; (2) technology considerations; app content, usage and outcomes; and (3) individual and environmental considerations; parental and professional elements, and workload. A FARR app prototype was developed based on the data.

Conclusion The prototype app provides a platform to develop a coordinated and consistent technological approach to paediatric FARR that acknowledges cultural nuances and preferences, ensuring that parents can communicate in a manner that aligns with their cultural background and communication abilities, thereby enhancing the quality of care delivered.
