# Algorithmic Block Management

*/Opportunities/Algorithmic_Block_Management*

## Opportunity Overview

**Wedge**: Target orthopedic and neurosurgery departments within mid-sized regional health systems. These specialties carry the highest contribution margins and longest backlogs, proving immediate multi-thousand-dollar ROI for every single recovered hour. From this departmental beachhead, the product expands horizontally to all surgical specialties in the facility, then extends to the health system's affiliated ambulatory surgery centers.
**Timing**: Hospitals now mandate FHIR-based EHR integration, enabling external applications to read schedules and write appointments in real time. Concurrent advances in predictive modeling allow systems to accurately flag blocks likely to go unused days before the static release deadline.
**Why This I C P**: Perioperative Directors control the highest revenue-generating asset in the hospital. They face intense margin pressure and possess the immediate authority to adopt tools that increase case volume without adding physical infrastructure.
**Size Of Prize**: There are approximately 3,500 acute care hospitals in the US operating high-volume surgical suites. At an estimated annual software contract value of $100,000 per facility to automate block reallocation, the total addressable market is roughly $350M.
**Gap Narrative**: Hospitals assign operating room time in static blocks, leading to unused gaps when surgeons cancel or finish early. Current EHR modules require manual block release and frantic phone calls to fill open slots. Perioperative directors need a system that detects underutilized blocks and programmatically reallocates them to surgeons with patient waitlists.
**Defensibility**: Defensibility stems from deep workflow lock-in and a compounding data asset. As the algorithm ingests more scheduling behaviors, it builds proprietary accuracy regarding which specific surgeons consistently underutilize blocks and which reliably fill last-minute openings. Once clinic schedulers rely on automated text prompts to clear their surgical backlogs, replacing the tool severely disrupts the hospital's revenue pipeline.
**Why This Thesis**: An agentic, Service-as-Software approach bypasses the need for surgeon adoption of new interfaces. By operating via SMS and direct EHR write-backs, the system functions as a digital scheduling assistant, matching the asynchronous, mobile-first reality of busy surgical clinic coordinators.

## Opportunity Market Sizing

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**S A M**: ~$300-450M US independent ambulatory surgery centers and regional health systems
**S O M**: ~$15-35M
**T A M**: ~11,500 US ambulatory surgery centers and hospital surgical departments × ~$80,000/yr ≈ ~$920M
**Growth Rate**: ~12-16%/yr, driven by the rapid migration of higher-acuity surgical procedures to outpatient settings and margin pressures demanding maximum OR utilization
**Paid Comparable Spend**: ~$65k-130k/yr per facility in fully burdened costs for dedicated OR scheduling coordinators, manual block committee administrative time, and legacy EHR scheduling modules

## Opportunity Win Conditions

**Kill Thresholds**:
- Less than 20% of unused blocks released prior to the 14-day auto-release window by day 60
- Manual scheduler override rate exceeds 40% in month 2
- EHR integration and mapping time exceeds 45 days per facility
- Pilot conversion rate to paid contract falls below 25% at day 90
**Leading Metrics**:
- Average block release lead time in days
- Percentage of released blocks rebooked within 48 hours
- Manual override rate by facility schedulers
- Surgeon clinic staff weekly active usage
- Time-to-first automated block reallocation
**What Proves Right**: Success requires ambulatory surgery centers executing their OR block release and request workflows entirely outside of manual spreadsheets. Schedulers reallocate unused time at least 14 days in advance, directly increasing prime-time utilization. Surgeons and their clinic staff claim open blocks via the interface without placing phone calls to the facility.
**What Proves Wrong**: Facility schedulers revert to manual phone calls because they override the automated allocation rules. Surgeons hoard operating time until the 48-hour mark, completely ignoring the system's early release prompts. EHR integration hurdles block real-time case duration mapping, rendering the block allocation engine inaccurate and unusable.

## Opportunity Build Profile

**Hardest Part**: Accurately predicting case durations and last-minute cancellations from highly customized EHR data schemas without human intervention. The system must achieve a high enough confidence threshold to trigger automatic block reallocation without infuriating surgeons whose time is reassigned.
**Min Viable Scope**: V1 predicts unused OR block time and automates release requests for a single high-volume specialty like orthopedics. Deliberately exclude automated case rescheduling, surgical staffing optimization, and medical equipment conflict resolution.
**Cold Start Problem**: The predictive allocation engine requires thousands of historical case logs from a specific hospital EHR to calibrate accurately. Overcome this by securing a single mid-sized hospital pilot, extracting a static 12-month CSV export of OR scheduling data, and running the engine in shadow mode to prove accuracy before touching live HL7 feeds.
**Time To First Value**: 4-6 weeks of historical data ingestion and shadow-mode calibration before the first live block reallocation.
**Data Moat Available**: true
**Technical Difficulty**: High
