The exponential use of robotic surgery is not the result of evidence-based benefits but mainly driven by the manufacturers, patients and enthusiastic surgeons. The present review of the literature shows that robot-assisted surgery is consistently more expensive than video-laparoscopy and in many cases open surgery. The average additional variable cost for gynecological procedures was about 1600 USD, rising to more than 3000 USD when the amortized cost of the robot itself was included. Generally most robotic and laparoscopic procedures have less short-term morbidity, blood loss, intensive care unit, and hospital stay than open surgery. Up to now no major consistent differences have been found between robot-assisted and classic video-assisted procedures for these factors. No comparative data are available on long-term morbidity and oncologic outcome after open, robotic, and laparoscopic gynecologic surgery. It seems that currently only for very complex surgical procedures, such as cardiac surgery, the costs of robotics can be competitive to open surgical procedures. In order to stay viable, robotic programs will need to pay for themselves on a per case basis and the costs of robotic surgery will have to be reduced.
Screening patients' nutritional status on admission to hospital is recommended by evidence-based guidelines on malnutrition. In practice, self-reported values for body weight and height are often used by nurses and dieticians. This study assessed the accuracy of self-reported body weight and height and whether these self-reported values might be influenced by the nature of the health-care worker involved. Patients (n = 611) on admission reported their body weight and height to a nurse and a dietician. Reported values were analysed and compared with the measured values. Self-reported values for body weight and height on admission are not always accurate. Patients do report different values to different health-care workers. Self-reported values for body weight to nurses were more accurate as compared with dieticians. Self-reported values for body weight and height are subject to observer bias and should be used with caution in nutritional screening and multi-professional nutritional care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
