- How useful is mixed reality in surgical treatment? - a Delphi StudyPublication . Magalhães, Renato; Lima, Ana Carolina; Marques, António; Pereira, Javier; Pereira da Silva Marques, António José; Magalhães, RenatoMixed reality (MR) is a tool that integrates elements from both the real and virtual worlds. Its potential applications are manifold, with promising developments observed in diverse fields, including healthcare, particularly in the context of surgical procedures. A number of studies have been conducted on mixed reality headsets, including the Microsoft HoloLens 2®, which may be employed in surgical training, planning, and navigation. It is imperative to ascertain whether medical professionals consider this technology indispensable in their professional lives. This study employs the Delphi method to assess the utility of MR in surgical settings and utilizes the Welphi online platform to facilitate this process. Furthermore, a PRISMA-like approach is employed to analyze the results of the initial round. The objective of this study is to examine the feasibility and advantages of mixed reality technology in surgical contexts. The findings are intended to inform and direct healthcare professionals, researchers, and developers in the advancement of mixed reality integration in surgical environments, with the ultimate goal of optimizing the quality and safety of treatments. A Delphi approach comprising of three rounds was implemented to ascertain consensus on the utility of MR surgical treatment. Participants were purposefully selected from experts with professional experience with technologies that provide a more immersive or interactive experience, such as virtual reality (VR), augmented reality (AR), 3D laparoscopy, robotics, and other similar technologies applied in the surgical field. The initial round of the study was designed to allow surgeons to provide their insights into the potential applications of MR in surgical procedures. This phase employed a structured approach, with open-ended questions organized into five distinct sections. In the second round, the questions were derived from the analysis of the first round and organized according to main and sub-topics for hierarchical structuring. In the third round, the questions were identical to those posed in the second round, including the percentage results obtained in the previous round. This afforded the experts the opportunity to review their previous responses. A consensus round was subsequently conducted. In the analysis, Kendall's tau-b coefficient for correlation analysis was employed and significant correlations between distinct aspects were identified. Twenty-two of the invited experts provided responses in both the initial and subsequent rounds, representing a 100% response rate. In the third round and consensus round, 20 experts participated, representing 91% response rate. The consensus round was conducted to present the results that had achieved a level of majority consensus of 95% on the usefulness of MR in surgical treatment. The objective was to have experts validate the results. The primary benefits of MR in surgery were identified as surgical navigation (with 75% of consensus), surgical planning (with 75% of consensus), and teaching and training (with 70% of consensus). According to the Delphi study, the areas where MR technology is most beneficial in surgical contexts are surgical navigation, training, and planning. However, the costs and investments required for implementation may present a potential limitation for the integration of this technology in surgical procedures. Moreover, it is of crucial importance to comprehend the ethical implications associated with this matter, which may have implications for the security of patients.
- Mixed reality in surgery: Development of a mixed reality application for surgical trainingPublication . Lima, Ana Carolina; Vilaça, Adélio; Veloso, Rita; Marques, António; Pereira, Javier; Magalhaes, Renato; da Silva Veloso, Rita Sofia; Pereira da Silva Marques, António José; Magalhães, RenatoMixed reality (MR) technology combines the real and the virtual world in an innovative way, where the users can see and interact with both worlds at the same time, having several applications in surgical practice, planning, and training. A MR application was developed to be used in a head mounted display (Microsoft HoloLens 2) for surgical training of the anterior cruciate ligament reconstruction surgery, with the aim of indicating the position of the femoral tunnel. This application was tested by 11 surgeons of the Centro Hospitalar Universitário de Santo António, who have all completed the simulation successfully, with an average time of under a minute. These surgeons answered an inquiry of satisfaction, where they all highlighted the potential that MR has in surgical training.
- Usefulness of mixed reality in surgical treatment: Delphi studyPublication . Magalhães, Renato; Lima, Ana Carolina; Marques, António; Pereira, Javier; Santos. Lúcio Lara; Pereira da Silva Marques, António José; Magalhães, RenatoMixed reality (MR) combines real and virtual elements and has shown promise in diverse fields, including surgical procedures. MR headsets may support surgical navigation, planning, and training. It is crucial to determine whether medical professionals consider this technology indispensable. This study uses the Delphi method, facilitated by the Welphi web-based platform, to assess the utility of MR in surgical settings and analyzes the results of the first round using a systematic approach modeled on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework. This study aims to examine the feasibility and advantages of MR technology in surgical contexts. The findings are intended to inform and direct health care professionals, researchers, and developers in advancing MR integration into surgical environments to optimize treatment quality and safety. A 3-round Delphi approach was implemented to ascertain consensus on the utility of MR in surgical treatment. Participants (n=22) were purposefully selected from among experts with professional experience in technologies such as virtual reality, augmented reality, 3D laparoscopy, and robotics. In the first round, participants provided insights into the potential applications of MR in surgical procedures through open-ended questions structured across 5 distinct sections. Responses were analyzed to develop the second-round questionnaire, which was hierarchically organized into main topics and subtopics. In the third round, the questions were identical to those in the second round, including the percentage results, allowing participants to reconsider their responses. A consensus round was subsequently conducted. The majority consensus level was defined as agreement by ≥70% of the participants in a given round. The study was conducted from January to May 2024. All 22 invited experts provided responses in both the first and second rounds (100% response rate). In the third and consensus rounds, 20 (91%) of the 22 experts participated. The consensus round, conducted to present the results, yielded a majority consensus (19/20, 95%) on the usefulness of MR in surgical treatment. The primary benefits of MR in surgery were identified as surgical navigation (15/20, 75%), planning (15/20, 75%), and teaching and training (14/20, 70%). In addition, 75% (15/20) of the experts identified cost and investments as primary constraints. We used the Kendall tau-b coefficient for correlation analysis, and significant correlations were identified between distinct aspects. MR technology is most beneficial in surgical navigation, planning, and training. However, the costs and investments required for implementation may present a potential limitation for the integration of this technology into surgical procedures. Moreover, it is of crucial importance to consider the ethical implications associated with MR use, particularly regarding patient safety and privacy.
