Scorecards are refreshed nightly. Changes from today’s validated cases will appear in tomorrow’s scores. The algorithm intentionally uses peer comparison within procedure cohorts, so scores reflect relative performance, not absolute thresholds.
Four pillars
Each surgeon is scored across four pillars that measure different aspects of operational performance:| Pillar | Weight | What it measures |
|---|---|---|
| Profitability | 30% | Profit per case compared to peers in the same procedure cohort |
| Consistency | 25% | Timing variability (coefficient of variation) across case durations per procedure |
| Schedule Adherence | 25% | How closely actual case durations match scheduled/booked times |
| Availability | 20% | Prep-to-incision gap and surgeon delay rate |
Scoring methodology
MAD-based scoring (Profitability & Consistency)
These pillars use Median Absolute Deviation instead of standard deviation:- Median-anchored — the center of the scale is the median of the procedure cohort, not the mean
- 3 MAD bands — it takes 3 MADs from the median to reach the floor (10) or ceiling (100)
- Volume-weighted — scores are calculated within procedure cohorts, then weighted by each surgeon’s case mix
Graduated decay (Schedule Adherence & Availability)
These pillars use direct graduated scoring with no peer comparison: Each case receives a score from 0 to 1.0 using linear decay (e.g., a case that starts 10 minutes late scores lower than one starting 5 minutes late). The pillar score is the mean of all case scores, scaled to 0–100. This approach produces a meaningful absolute score — 77% means “77% on-time effectiveness” without a confusing relative layer on top.Composite calculation
Grade thresholds
| Grade | Score range | Description |
|---|---|---|
| A | ≥ 80 | Elite — top performer |
| B | ≥ 65 | Strong — above average |
| C | ≥ 50 | Developing — meeting expectations |
| D | < 50 | Needs improvement |
Surgeon scorecards
Each surgeon is displayed as a scorecard showing:- Score ring — animated circular gauge (0–100) with letter grade
- Pillar bars — four horizontal progress bars with raw score and weighted contribution
- Case count and flip-room indicator
- Trend arrow — comparison vs. prior period
- Procedure breakdown — top 5 procedures with case counts
Sort options
Sort surgeons by composite score (default), trend, case volume, or name.Facility summary
A summary strip at the top shows:- Facility average composite score
- Total surgeons scored
- Total cases analyzed
- Grade distribution (count of A/B/C/D grades)
Improvement plans
Each surgeon can expand an AI-generated improvement plan showing:- Summary — current composite → projected composite, with annual time saved and financial value
- Strengths — pillars scoring ≥80 with positive reinforcement
- Recommendations — per-pillar improvement cards with:
- Current score → target score
- Composite impact (points gained)
- Actionable steps
- Projected annual savings (hours and dollars)
Data requirements
Surgeons need a minimum number of cases (default: 15) to receive a score. Below this threshold, an “Insufficient Data” notice is displayed instead of a scorecard.FAQ
Why did a surgeon's score change without new cases?
Why did a surgeon's score change without new cases?
Because Profitability and Consistency use peer comparison (MAD-based), a surgeon’s score can change when other surgeons in the same procedure cohort have new cases validated. Their position relative to the cohort median shifts even without their own new data.
What does 'volume-weighted' mean for scoring?
What does 'volume-weighted' mean for scoring?
A surgeon who performs 50 knee replacements and 5 hip replacements gets their score weighted heavily toward knee replacements. This prevents a niche procedure with only a few cases from dominating the composite score.
Can I adjust the pillar weights?
Can I adjust the pillar weights?
Pillar weights (30/25/25/20) are currently fixed in the scoring algorithm. Future versions may support facility-level weight customization.
How do improvement plans calculate projected savings?
How do improvement plans calculate projected savings?
Improvement plans estimate savings by projecting how many minutes/dollars would be saved if the surgeon moved from their current pillar score to the target score, multiplied by their annual case volume.
