Pain and anxiety management with virtual reality for office hysteroscopy: systemic review and meta-analysis

Abstract

Purpose: Office hysteroscopy (OH) is a commonly performed procedure, although it might be associated with some degree of pain and anxiety. Our aim was to determine the effects of virtual reality on pain and anxiety levels felt by patients undergoing OH.

Methods: MEDLINE, Embase, Google Scholar, Cochrane Library, clinicaltrials.gov, ProQuest, Grey literature, and manual searching of references within studies found in the initial search were systematically searched using the terms 'Virtual Reality' and 'Hysteroscopy' without time or language limitations. The review considered all studies assessing the impact of virtual reality (VR) over OH outcomes, and prospective randomized trials were included in the meta-analysis. Retrospective and case - control studies were excluded from the meta-analysis.

Results: We identified 17 studies, of which four randomized controlled studies were included in the meta-analysis (327 participants, 168 in the VR group and 159 in the control group). On a 0-10 scale, pain sensation and maximal pain sensation during the operation were not statistically different between study and control groups (relative risk (RR) = -0.64, 95% C.I (-1.57)0.29) and (RR = -0.93, 95% C.I (-3.33) - 1.47), respectively. Anxiety measurement was statistically lower in the study group (RR = -1.73, 95% C.I (-2.79) - ( -0.67)).

Conclusions: The available data suggest that VR techniques do not decrease the pain sensation during OH however, they do contribute to a reduction in the anxiety levels experienced by patients. PROSPERO registration number CRD42023432819.
