Algorithm for anesthesiology group productivity for surgical anesthesia that may be used for comparisons of facilities covered by one group. tASA/FTE is determined by three factors: tASA/OR, OR/OR FTE, and OR FTE/FTE. Because the OR/OR FTE and OR FTE/FTE are defined and determined locally, the use of tASA/FTE can only be used by a group when comparing facilities that the group covers and cannot be used to compare to industry survey data. Base/case, base units per case; FTE, full time equivalent; h/case, case duration = billed hour per case; h/OR/day, billed hour per site per weekday; OR, anesthetizing site; OR FTE / FTE, % time spent providing care that is billed using ASA units excluding obstetric anesthesia; OR sites / OR FTE, Concurrency or staffing ratio at beginning of workday; tASA/FTE, total ASA units/FTE; tASA/OR, total ASA units per site.
