RESUMO
PURPOSE: Patients undergoing medical procedures often experience pain and anxiety. These periprocedural outcomes can be overcome by providing a distraction using virtual reality (VR), decreasing their perception. VR has proved effective in reducing pediatric pain and anxiety; however, limited studies have confirmed its effectiveness in adults. We performed a systematic review and meta-analysis on the effectiveness of VR, as opposed to standard care, in reducing periprocedural pain and anxiety in adults. METHODS: A systematic search of randomized controlled trials was conducted using the databases of MEDLINE, Cochrane CENTRAL, and Scopus. Trials involving patients (> 18 years) undergoing elective medical procedures conducted with or without local anesthesia and participating in VR therapy were included. Primary outcomes were pre-procedural anxiety, post-procedural anxiety, and intra-procedural pain. Pre-procedural pain, post-procedural pain, and intra-procedural anxiety were secondary outcomes. RESULTS: Data from 10 studies shortlisted for inclusion revealed no significant association between the use of VR and lower pre-procedural anxiety compared to standard care (p > 0.05) (SMD = -0.02, 95% CI = -0.18 - 0.14, P = 0.81) but demonstrated that the use of VR was significantly associated with a reduction in post-procedural anxiety (SMD = -0.73, 95% CI = -1.08 - -0.39, P < 0.0001), intra-procedural pain (SMD = -0.61, 95% CI = -1.18 - -0.04, P = 0.04), and post-procedural pain (SMD = -0.25, 95% CI = -0.44 - -0.05, P = 0.01). CONCLUSION: The use of VR caused a significant reduction in post-procedural anxiety, intra-procedural pain, and post-procedural pain in adults undergoing medical procedures, although the findings were insignificant concerning pre-procedural anxiety.
