Monitoring surgical performance [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 2004 doi:10.1016/j.jtcvs.2004.03.022 I f surgical performance—often measured by postoperative outcome of initial hospital stay—is monitored at all, the most common means is by risk-adjusted annual or semiannual audit. Observed occurrence of outcome measures (eg, in-hospital death and complications) as a proportion of cases performed is compared with ...
