BACKGROUND Previous studies of operating room (OR) information systems data over the past two decades have shown how to predict case durations using the combination of scheduled procedure(s), individual surgeon and assistant(s), and type of anesthetic(s). We hypothesized that the accuracy of case duration prediction could be improved by the use of other(More)
BACKGROUND Theoretically, communication systems have the potential to increase the productivity of anesthesiologists supervising anesthesia providers. We evaluated the maximal potential of communication systems to increase the productivity of anesthesia care by enhancing anesthesiologists' coordination of care (activities) among operating rooms (ORs).

BACKGROUND Surgeon estimates of case durations are important for operating room (OR) management decision making because many cases are rare combinations of procedures with few or no historical data. Thoracic and spine surgeons updated their scheduled OR times on the day of surgery just before the "time out" in the OR. METHODS All elective (scheduled)(More)
BACKGROUND We recently determined how to use anesthesia information management system data to model the time from end of surgery to extubation. We applied that knowledge for meta-analyses of trials comparing extubation times after maintenance with desflurane and sevoflurane. In this study, we repeated the meta-analyses to compare isoflurane with desflurane(More)
PURPOSE We investigated whether changes in the number of cases performed by surgeons can be used as an appropriate surrogate for anesthesia departments' billed units. METHODS We used both number of cases performed and the American Society of Anesthesiologists' Relative Value Guide™ (ASA RVG) units to assess all operating room anesthetics of an anesthesia(More)
BACKGROUND Perception of turnovers may be influenced less by actual turnover times per se than by a mental model of factors influencing turnover times. METHODS A survey was performed at a U.S. academic hospital in 2010. Each of the 78 subjects estimated characteristics of his/her turnover times in 2009. Responses were compared with the actual times.

BACKGROUND Anesthesia department planning depends on forecasting future demand for perioperative services. Little is known about long-range forecasting of anesthesia workload. METHODS We studied operating room (OR) times at Hospital A over 16 yr (1991-2006), anesthesia times at Hospital B over 26 yr (1981-2006), and cases at Hospital C over 13 yr(More)
BACKGROUND Anesthesiologists are often paid extra for hours worked in the late afternoon and evening. Although anesthesiologists have little influence on their operating room (OR) assignments and workloads late in the afternoon, they can influence turnover times. METHODS OR turnover times on workdays were reviewed for n = 30 mo before there was(More)
To the Editor, Arakelian et al. [1] studied qualitatively surgical teams' perceptions of operating room (OR) efficiency. Although they state that 'the lack of studies of this kind rendered it difficult to compare the results with those of others', psychological studies complement the authors' organizational (sociological) investigations [1, 2]. OR(More)
BACKGROUND The economic costs of reducing first case delays are often high, because efforts need to be applied to multiple operating rooms (ORs) simultaneously. Nevertheless, delays in starting first cases of the day are a common topic in OR committee meetings. METHODS We added three scientific questions to a 24 question online, anonymous survey performed(More)
