ObjectivesMixed-reality (MxR) implementation in the neurosurgical operating room (OR) is emerging, but the impact of this technology on the nonsurgical OR staff has not been investigated yet. The purpose of this study is to evaluate the nonsurgical OR team's perception of the impact of intraoperative MxR use.MethodsThe evaluation occurred in a neurosurgical institution implementing MxR perioperatively on a daily basis for 15 months. The questionnaire measuring the impact of MxR consisted of 5 binary questions and 4 subquestions measured on a 7-point Likert scale.ResultsFifteen nonsurgical staff members of a neurosurgical OR team were interviewed. Most (85%) of the cohort stated that MxR changed their perception of the surgery, improving understanding of the spatial orientation (median 6, interquartile range 5-7) and of the pathology dimensions (6, 5.5-7). One participant (7%) was of the opinion that MxR disrupted the OR workflow. The majority (60%) stated that use of the holograms improved efficiency in the OR. The participants were neutral about the potential role of MxR to improve communication among different OR team members (4, 2-5) and overall teamwork (4, 2-5).ConclusionsThe use of 3-Dimensional interactive holograms of neurosurgical cases in the nonsterile intraoperative phase was not perceived as distractive, and neither was OR flow disruption by members of the nonsurgical OR staff. MxR was considered an adjunct to improve OR efficiency. A thorough understanding of the impact of MxR's implementation on the nonsurgical staff could lead to targeted improvement of the MxR use and, potentially, to increasing the quality of the teamwork.Copyright © 2023 The Author(s).
