Socially Assistive Robots for Pain Management and Emotional Responses in Pediatric Hospital Care: Systematic Review and Meta-Analysis

Editorial reading guide · Kindness

Does evidence that a hospital robot eases pain also mean it reliably reduces fear or distress?

Helps parents separate physical comfort from broader emotional claims. Pooled pain outcomes favored social robots, while anxiety, fear and distress estimates were nonsignificant with wide uncertainty. Different comparators, settings and robot control modes matter: the review does not validate any one autonomous emotional-caregiver product.

Study context

13 pediatric-hospital randomized trials, 619 participants; seven trials contributed to meta-analyses.

Age / stage: Eligibility under 19; included trials reported ages 2–19, predominantly school-age

Read with three questions

1. Why do the pooled pain results differ from the nonsignificant anxiety, fear and distress results?
2. How do prediction intervals change expectations for a child in a new hospital context?
3. Which studies used teleoperation, scripted sequences or autonomous behavior, and why should that distinction shape a GenAI comparison?

Keep the limits in view

Only a few trials per pooled emotional outcome, heterogeneous measures and comparators, nonblinding and moderate certainty. Small numbers limit subgroup and publication-bias analyses. Acute hospital evidence does not establish lasting social-emotional development or safe replacement of human comfort. Review eligibility and reported upper age boundary differ slightly.
