Meta-analyses suggest that virtual reality (VR) reduces self-reported pain, fear, and anxiety in children during needle procedures but has high heterogeneity, high overlap between primary studies, and low methodological quality, leading to a "very weak" GRADE (Grading of Recommendations Assessment, Development and Evaluation) classification. Clinicians should view VR as a promising additional distraction tool; however, VR cannot yet replace current analgesic and anxiolytic strategies. Future research should focus on age-stratified analyses, measurement tool standardization, and modern VR technology |
