Effectiveness of Virtual Reality for Managing Pain, Fear, and Anxiety in Children and Adolescents Undergoing Needle-Related Procedures: Systematic Review with Meta-Analysis.

The most frequently performed invasive procedures in hospitals and healthcare centers are needle-related procedures, such as intravenous cannulation and phlebotomy, and they are identified as the major sources of pain, fear, and anxiety in children and adolescents. The objective of this systematic review was to evaluate the effectiveness of VR as a distraction measure to reduce pain, fear, and anxiety in children and adolescents undergoing needle-related invasive procedures. For this purpose, the CINAHL, Scopus, WOS, and Cochrane Library scientific databases were used. The protocol review was registered in PROSPERO (ID:42024563245), and inclusion and exclusion criteria were applied. Twenty-one studies were included in the systematic review, involving a total of 2663 participants. Significant differences favored the use of virtual reality for the control of pain intensity (WBFSpatients = 0.001; MD = -1.83; 95% CI -2.93 to -0.72; WBFSparents = 0.0002; MD = -2.61; 95% CI -4.00 to -1.23; WBFSnurses = 0.0001; MD = -2.71; 95% CI -2.82 to -2.60; VAS/NRS = 0.001, MD = -0.71; 95% CI -1.13 to -0.28), anxiety (CAMpatient = 0.02, MD = -2.92; 95% CI -5.45 to -0.38; CAMparents = 0.01, MD = -3.87; 95% CI -6.99 to -0.75) and fear (CFSpatients = 0.0005, MD = -1.27; 95% CI -1.99 to -0.56; CFSparents = 0.0005, MD = -1.33; 95% CI -2.08 to -0.58; and CFSnurses = 0.04, MD = -1.13; 95% CI -2.24 to -0.03). However, high heterogeneity was noted. The use of virtual reality as a distraction appears to be a valuable strategy for reducing pain, fear, and anxiety during needle-related procedures, although further studies with higher methodological rigor, based on a standardized protocol, are needed.
