The hybrid surgical suite Basic equipment and design of the hybrid endovascular operating room § A fully integrated interventional hybrid operating room combines: Ø high level surgical sterility Ø flat-panel cardiovascular imaging, Ø a linked workstation with post processing and storage facilities § The imaging system must provide superior image quality, higher tube heat capacity Imaging techniques in the hybrid operating room • Rotational angiography is a medical imaging technique based on x-ray, that allows to acquire CT-like 3D volumes using a fixed C-Arm. • The fixed C-Arm thereby rotates around the patient and acquires a series of x-ray images that are then reconstructed through software algorithms into a 3D image. • Commercial name for Siemens is DynaCT Imaging techniques in the hybrid operating room • Rotational angiography versus angio CT • The patient positioning on the CT scanner table differs from the positioning on an interventional table during hybrid surgery, • Intraoperative 3D imaging with rotational angiography is much more precise and can be performed with rapid ventricular pacing.

Coronary artery disease: Hybrid procedure • Hybrid coronary revascularization, combining the LIMA-LAD graft and DES to non-LAD vessels, might become a very good revascularization alternative in multivessel CAD. • In hybrid OR we are able to perform a simultaneous approach, checking the result of surgical graft and completing revascularization in a single procedure • This “one stop” approach improves efficiency and reduces cost, and it may also help to reduce the risks associated with patient transfers and handoffs. • We believe that widespread initiation of a successful hybrid program hinges on the adoption of a multidisciplinary approach to hybrid thinking, with good collaboration between interventional cardiologists and cardiac surgeons. • Furthermore, it is critical that the expertise of both parties is comparable because implementing hybrid practice in a center more experienced in 1 revascularization modality than the other could be detrimental Hybrid coronary procedure: when? • YES if: Ø It is always an option for patients unsuitable for conventional surgery.

In a hybrid OR, the staff have to manage the technique confidently in a not completely familiar environment and still be able to care for the vulnerable patient in the safest way. The overall aim of this thesis was to explore and describe the care and work processes, staff interactions, and experiences of both patients and staff in the hybrid OR. Data were collected through 18 individual interviews, nine video recordings of endovascular aortic repairs (EVARs) and five focus group interviews. Data were mainly analyzed qualitatively (hermeneutic, hermeneutic phenomenology and qualitative content analysis) but also with the use of descriptive statistics. The environment in the hybrid OR was experienced as safe by both patients and staff.

  • Improved Efficiency and Safety for EVAR with Utilization of a Hybrid
    Improved Efficiency and Safety for EVAR with Utilization of a Hybrid Room5 V.N. Varu, J.I. Greenberg, J.T. Lee * Division of Vascular Surgery, Stanford University Medical Center, Stanford, CA, USA WHAT THIS PAPER ADDS This study is novel in that it shows for the first time inherent differences in doing endovascular aneurysm repair with a standard fluoroscopy versus hybrid operating room setup. The implication is that ultimately a hybrid room may be safer and more efficient in the long run, and perhaps a valued investment by hospitals across the world. Objective: Access to a hybrid endovascular suite is touted as a necessity for advanced endovascular aneurysm repair (EVAR) to improve imaging accuracy and safety. Yet there remain little data documenting this intuitive advantage of a hybrid setup versus a traditional operating room (OR) utilizing a portable fluoroscopic unit (C-arm) for imaging. We hypothesized that standard elective EVAR performed in a hybrid suite would improve procedural efficiency and accuracy, as well minimize patient exposure to both contrast and radiation. Methods: We retrospectively reviewed a single attending surgeon’s EVAR practice, which encompassed the transition to a hybrid endovascular suite (opened July 2010). Only consecutive abdominal aneurysms were included in the analysis to attempt to create a homogenous cohort. All emergent, aorto-uni-iliac (AUI), snorkel, fenestrated, or hybrid procedures were excluded. Standard variables evaluated and compared between the two study subgroups included fluoroscopy time, operative time, contrast use, stent-graft component utilization, complication rates, and short-term endoleaks. Results: From January 2008 to August 2012, we performed 213 EVAR procedures for abdominal aortic aneurysms.

  • Imaging Meets Surgery – the Hybrid OR
    Biomed Tech 2012; 57 (Suppl. 1) © 2012 by Walter de Gruyter · Berlin · Boston. DOI 10.1515/bmt-2012-4041 Imaging meets Surgery – The Hybrid OR C.J. Bulitta, MD, Siemens AG Healthcare Sector, Forchheim, Germany, [email protected] Abstract Introduction: The merger of interventional and open surgical procedures leads to novel approaches in various clinical fields. Imaging becomes a critical tool and success factor because it allows for visualization of the targeted anatomical structures and leads the way for the clinician. Moreover high-end imaging (Angiography, CT, MRI) available in the op- erating room allows for assessment of treatment results immediately at the point of care which helps to avoid complica- tions and the need for revision surgery. Methods: Operating rooms in various clinical fields are equipped with high-end imaging systems. The most prominent example is the angiography system in cardiovascular operating theatres. Require- ments for imaging and other medical equipment vary among clinical specialties. Infrastructure and building technology are also important topics for planning and implementation. Workflow and hygienic requirements should not be forgotten. Thus building a hybrid OR is a complex technical challenge. Based on the experience of more than 400 installed an- giography systems in Operating Rooms in more than 30 countries worldwide we have put together lessons learned and recommendations for planning and implementation. Results: Planning needs to consider all aspects and components from building technology to medical equipment. Early planning and room design with all stakeholders and balancing clinical requirements and technical feasibility is critical for success. Hygienic requirements vary significantly and there- fore should be discussed and considered according to local regulations.

Therefore, this study aims to identify the cost drivers of a conventional and ePublished: 27 July 2020 hybrid OR and take a first step in evaluating the added value of the hybrid OR. Methods: A comprehensive bottom-up cost analysis was conducted in five Dutch hospitals taking into account: construction, inventory, personnel and overhead costs by means of interviews and hospital specific data. The costs per minute for both ORs were calculated using the utilization rates of the ORs. Cost drivers were identified by sensitivity analyses. Results: The costs per minute for the conventional OR and the hybrid OR were €9.45 (€8.60-€10.23) and €19.88 (€16.10- €23.07), respectively. Total personnel and total inventory costs had most impact on the conventional OR costs. For the hybrid OR the costs were mostly driven by utilization rate, total inventory and construction costs.
