Table 2. Departmental Productivity Measurements

Productivity measurements calculated from data collected as in table 1. Hours per OR site per day (h/OR/days) are estimated by using 250 days per year (= 50 weeks/year × 5 days/week) for all groups. Because 15-min time units were used, 1 h = 4 time units.

OR sites = anesthetizing sites; FTE = full-time equivalent; ASA = American Society of Anesthesiologists; tASA = total ASA units; TU = time units.
