# Maccabi Healthcare Services: Prostate Pathology Quality Control

Second-read quality control is too labor-intensive to perform on 100% of cases.

Function: Clinical operations. Patterns: Exception-based operations; Human quality loop. Evidence: verified.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 1 peer reviewed; publication outcomes are verified.

## Before

1. **Pathologist** — Perform primary diagnosis on prostate biopsies (control: Not published.)
2. **Pathologist (Quality Control)** — Manually review a small sample (e.g., 10%) of cases for quality control (control: Sample-based human QA)

## After

1. **Pathologist** — Perform primary diagnosis on prostate biopsies (control: Not published.)
2. **AI System** — Analyze 100% of digitized slides as a second-read control and raise alerts for discrepancies (control: 100% AI QA coverage)
3. **Pathologist** — Review AI alerts (minimal time cost) and order additional cuts/stains if necessary (control: Human override and final diagnosis)

## Decision rights

AI raises alerts; human pathologist reviews alerts and makes the final diagnostic and procedural decisions.

## Exception path

Alerts indicating missed cancer or significant grading differences lead to additional cuts, stains, or third-opinion requests.

## Outcomes

- **Quality control coverage** (verified): 10% → 100%. The 10% baseline is a general industry practice estimate, not Maccabi's measured prior practice.
- **Time cost of quality control** (verified): Not specified → ~1%. Author estimate based on alert volume.

## Executive lesson

AI enables 100% quality control coverage where manual sampling was previously the only economically viable option.

## Anti-pattern

Assuming 100% AI screening requires 100% human re-review.

## Questions for leaders

- What critical QA processes are currently sampled at 10% because 100% is too expensive?
