Can I validly monitor turnover times or first case of the day starts by anesthesiologist?
The validity of comparing average turnover times among anesthesiologists is limited. Click here [PDF] for details. First, 4 turnovers in a day are not N = 4 independent random samples of turnovers. Thus, correlations among turnovers need to be modeled statistically. Second, if an anesthesia group has 40 anesthesiologists, resulting in 40 confidence intervals to be compared to one another, the family-wise error rate needs to be controlled. Third, turnover times need to be adjusted for the preceding and following procedures and patients. Not only is something simplistic like general surgery absurdly insufficient because of heterogeneity in setup and cleanup times among procedures within a specialty, but turnovers often involve cleaning up from one specialty and setting up for a procedure of a different specialty. The usefulness of monitoring turnover times by individual anesthesiologist is also limited. Click here [PDF] for details. Suppose that each anesthesiologist were responsible for
