Impact of ethnicity on parental health outcomes and experiences after paediatric intensive care unit discharge: a mixed-methods systematic review

The impact of ethnicity on parental health outcome after paediatric intensive care unit (PICU) discharge remains unclear. Thirteen medical and healthcare databases, unpublished studies and grey literature were searched up to November 5, 2021. We performed a mixed-method systematic review to understand the impact of ethnicity on parental outcomes after PICU discharge, including eight quantitative and eight qualitative studies. Among 1529 parents included, 1064 (72%) were White. Higher prevalence of post-traumatic stress disorder was seen in Black parents (17% White vs 36% Black, p = .03). Latino ethnicity was found to have protective effect against anxiety as compared to White parents (coefficient - 4.27, p < .001). A total of 91 findings were aggregated into 14 categories, and the five synthesized themes from the eight qualitative studies were long-term psychological impact after PICU, use of coping strategies, challenges of re-integration, changes in relationships and the utilization of formal support services and resources. Mixed-method synthesis found that parents of ethnic minority group were underrepresented (18%) and had higher attrition rates in a longitudinal study as compared to White parents following childhood critical illness. Conclusion: There are significant gaps in evidence related to the impact of ethnicity on long-term parental health outcomes after PICU discharge. Ethnic diversity and inclusiveness in long-term PICU research may aid understanding of the parental experiences and outcomes to close the gap in health disparity. What is Known: Survival rates of paediatric critical illness have improved. Families of paediatric intensive care unit survivors continue to experience mental health issues, with 30% experiencing symptoms of post-traumatic stress 6 months after discharge. What is New: Parents from different ethnic backgrounds are underrepresented in paediatric critical care research. Minorities experience worse short-term outcomes after intensive care discharge.

Automated summary

The study reviewed the impact of ethnicity on parental health outcomes after PICU discharge, finding significant disparities in ethnic diversity in research and lower representation of ethnic minority parents in long-term studies.
