نبذة مختصرة : Background: Effective pain control is crucial to optimise the success of medical procedures. Immersive virtual reality (VR) technology could offer an effective non-invasive, non-pharmacological option to distract patients and reduce their experience of pain. We aimed to evaluate the efficacy of Immersive virtual reality (VR) technology in reducing patient’s pain perception during various medical procedures by conducting a systematic review and meta-analysis. Methods: We searched MEDLINE, EMBASE, CENTRAL, CINAHL, and SIGLE until December 2022 for all randomised clinical trials (RCT) evaluating any type of VR in patients undergoing any medical procedure. We conducted a random efect meta-analysis summarising standardised mean differences (SMD) with 95% confidence intervals (CI). We evaluated heterogeneity using I 2 and explored it using subgroup and meta-regression analyses. Results: In total, we included 92 RCTs (n=7133 participants). There was a significant reduction in pain scores with VR across all medical procedures (n=83, SMD−0.78, 95% CI−1.00 to−0.57, I 2=93%, p=<0.01). Subgroup analysis showed varied reduction in pain scores across trial designs [crossover (n=13, SMD−0.86, 95% CI−1.23 to−0.49, I 2=72%, p=<0.01) vs parallel RCTs (n=70, SMD−0.77, 95% CI−1.01 to−0.52, I 2=90%, p=<0.01)]; participant age groups [paediatric (n=43, SMD−0.91, 95% CI−1.26 to−0.56, I 2=87%, p=<0.01) vs adults (n=40, SMD−0.66, 95% CI−0.94 to−0.39, I 2=89%, p=<0.01)] or procedures [venepuncture (n=32, SMD−0.99, 95% CI−1.52 to−0.46, I 2=90%, p=<0.01) vs childbirth (n=7, SMD−0.99, 95% CI−1.59 to−0.38, I 2=88%, p=<0.01) vs minimally invasive medical procedures (n=25, SMD−0.51, 95% CI−0.79 to−0.23, I 2=85%, p=<0.01) vs dressing changes in burn patients (n=19, SMD−0.8, 95% CI−1.16 to−0.45, I 2=87%, p=<0.01)]. We explored heterogeneity using metaregression which showed no signifcant impact of diferent covariates including crossover trials (p=0.53), minimally invasive procedures (p=0.37), and among paediatric ...
