Beyond the First Case: Metrics that Matter More than FCOTS
In the first post in this series, we discussed why hospitals have long used first case on-time starts (FCOTS) as a benchmark for surgical suite efficiency. FCOTS are clear, easy to track, and easy to report. But while FCOTS look good on paper, they paint an incomplete picture of an operating room’s performance.
Understanding the drivers of OR inefficiency
To improve operational efficiency, it is important to understand where time is actually being lost. FCOTS still serve as a valuable metric, but they are just one piece of a much larger puzzle.
- Pre-operative inefficiencies. Delays from patient "wheels in" to the actual start of surgery can compound throughout the day.
- Extended turnover times. Delays between cases add up, resulting in overtime and staffing pressures.
- Poor case duration accuracy. Variations between scheduled and actual case times consistently contribute to cumulative delays.
None of these are reflected in FCOTS, and this is largely why FCOTS is limited in its effectiveness as an efficiency metric.

Adopting more comprehensive metrics
Hospitals need broader metrics to gain deeper insights and drive actionable improvements. Broader, more insightful data points help uncover hidden inefficiencies and guide targeted improvements. The following metrics offer a clearer picture of how the OR is performing:
- End-of-day performance. Metrics like percentage of ORs ending within 15 minutes of schedule highlight whether delays are absorbed or compounded throughout the day.
- Case duration accuracy. Measuring the variation between scheduled and actual procedure durations identifies chronic issues tied to specific surgeries, surgeons, or case types.
- All-case on-time starts. Offering a more holistic perspective than FCOTS alone, this metric captures how consistently OR teams remain on schedule throughout the entire day.
Rethinking OR efficiency
To improve performance, hospitals must build on FCOTS with metrics that capture the full rhythm of the day, including end-of-day performance, case duration accuracy, and all-case on-time starts. This additional data gives leaders a clearer view of where time is lost, where resources are stretched, and which improvements will have the greatest impact.
By broadening how operational efficiency is measured, organizations can reduce delays, make better use of staff, increase patient throughput, and, ultimately, drive stronger financial and clinical outcomes.
