Table 3.
Comparison of the durations of sub-processes related to instrumentation logistics.
| Process efficiency | |||
|---|---|---|---|
| The duration of the sub-processes related to instrumentation logistics is significantly (53%) shorter when using size-specific instrument sets, a remarkable contribution to process efficiency and cost reduction. | |||
| Sub-process in the OR | Standard instrumen-tation set (duration: min.) | Size-specifics instrumen-tation set (duration: min.) | Time saved (min.) |
| Preparation of all Instruments | 18:15 | 10:45 | 07:30 |
| Cleaning up OR | 10:30 | 04:38 | 05:52 |
| Total process time | 28:45 | 15:23 | 13:22 |
| Opportunity cost calculation: | |||
| If 4 Total Knee Arthroplasty procedures (TKA) were performed in one | |||
| OR a day 53 min will be saved | |||
| This time gained can be used for | |||
| Avoiding overtime in the afternoon or | |||
| Performing an another procedure achieving additional revenue | |||
