Implementation of a new robotic system: challenges for the surgical team and ethical concerns about patient safety, a longitudinal questionnaire study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The da Vinci robot continues to be the leading robotic system used in surgery. Following the expiry of its patent, many manufacturers started to develop other systems. We accompanied this sensitive initial phase of implementing a new surgical system in a clinic at which the previously established robotic system has completed its learning curve. Is it ethically justifiable to implement a new robotic system although an established, reliable and low-risk procedure is available? Research design and methods: We conducted a longitudinal and interdisciplinary questionnaire study from November 2022 to April 2023. Specific questionnaires - answered on a visual analog scale from 1 to 100 - were created for four target groups: surgeons, anesthesiologists, residents, and operating-room (OR) nurses. Results: A total of 63 participants filled the questionnaire and answered the tailored questions. While the surgeons, along with the OR nurses, initially had the greatest reservations about the Dexter robot and patient safety, their reservations lessened as the number of Dexter procedures performed increased. In contrast, the OR nurses were critical of the new robot and their ratings did not change as the number of Dexter procedures increased. Of all four groups, the residents rated the Dexter robot most positively. Conclusions: The establishment of a new surgical system that has been approved, yet not established so far, constitutes a major challenge with regard to ethical issues concerning patient safety. A standardized, mandatory curriculum for the entire surgical team would be desirable in order to achieve a similar level of technical expertise as that existing for the established robot system. In addition, we need comprehensible and transparent information for patients. To date, we lack regulations concerning these aspects, which are handled differently in the individual hospitals.
