Article Abstract
Introduction: Optimizing the processes involved in managing operating suite activities is an essential element in obtaining gains in efficiency. The early opening of surgical trays could represent an innovative practice for reducing operating times and wait periods between surgeries as well as for increasing the number of daily surgeries. The purpose of this systematic review is to assess the risks and benefits of introducing this practice in the operating room.
Methodology: A systematic literature review was conducted in various indexed databases as well as in the grey literature in order to identify synthesis studies, clinical guidelines and randomized and non-randomized studies on the impact of opening surgical trays early. The following indicators were sought: time lapse between the patient's entrance and the beginning of surgery, the frequency of surgical tray contamination, and the rate of surgical wound infection.
Results: An original study and four practice guides were included after a quality assessment. No studies on efficiency gains associated with the early opening of surgical trays were found. The results of the experimental study suggest that the contamination rate for uncovered surgical trays is low for the first 30 minutes (4%) and increases over time with exposure to the ambient air. Most clinical guidelines recommend preparing the surgical instruments as close to the beginning of surgery as possible without specifying the minimum time interval to be respected as well as whether or not the patient is in the operating room.
Discussion: The analysis- of all the available data does not make it possible to determine the optimal moment for opening the surgical trays. Given the uncertainty regarding the risks of infection, and the lack of data on the associated benefits, the decision to opt for a change in practice in the opening of surgical trays should be based on a range of factors. An assessment of the data therefore suggests caution and that a feasibility analysis, including a review of all processes and parameters for managing the risks associated with the early opening of surgical trays, be conducted before initiating any changes in the institutions where a change of practice is being sought.

Background: The Versius surgical system (CMR Surgical, Cambridge, UK) is a new robotic platform introduced after the original patent of the DaVinci system expired; it has already been applied in different fields, including gynaecology. Unlike DaVinci, Versius has four independent bedside units (BSU), which must be individually positioned with adequate angles and distance to avoid collisions. Given this peculiarity and the shorter arm (30 cm) compared to the Da Vinci, investigating BSU positioning and port placement is mandatory.

Background: Healthcare-related carbon dioxide emissions (COe) account for 8.5% of national greenhouse gas emissions, with high-volume disposable instrument use and high-energy sterilization of reusable instruments as large contributors. Instrument standardization for common surgical procedures has been shown to reduce cost, but few studies have evaluated the environmental impact of this practice.

Introduction: Robot-assisted technologies in total knee arthroplasty (TKA) have been introduced to increase implantation accuracy, minimize revisions, and ideally improve patient outcomes. However, concerns remain regarding increased costs and extended operating time. The aim of this study was to analyze the development of the cost structure of robot-assisted image-based knee arthroplasty in a specialized center over a 6-year period.

Hospital margins are falling and the need to control costs has become increasingly important for hospital and ambulatory surgery centers financial survival. The Braun CoreHip System allows reconstruction of the femoral offset independent of stem size. There are a maximum of 4 to 6 instrument trays thus minimizing sterilization costs and instrumentation.

Background: Medication errors are highly prevalent in the perioperative setting. The objectives of this study were to re-engineer the medication use process in the perioperative setting and to draft safety recommendations to improve safe medication use in daily practice.
Methods: A group coordinated by medical centre management and composed of pharmacists, surgeons, anaesthesiologists, nurses, and information technicians was formed in 2020.
