The challenge

AI scribes are new “employees” without rigorous performance checks

Black box AI technology makes every generated note unpredictable and potentially dangerous, creating significant liability for the organisations adopting it.

The problem today

AI scribes are now the newest “employee” providing healthcare outputs.
Academic literature shows up to 70% of AI notes contain errors.
Eager adopters are frustrated by errors.
Apprehensive clinicians are discouraged by the lack of transparency.

The result

Mistakes lead to poor trust and adoption.
Large investments and productivity gains aren’t realised.
Mistakes can cause poor patient care or patient harm.
The workforce becomes disillusioned with tools that don’t meet their needs.

Our solution: validated safety

To overcome these challenges and mitigate risks, CLEARvalidate provides independent, evidence-based validation, providing transparency — potentially detecting 80% of critical errors before they enter patient records.

Why validation matters

Why monitor AI scribes now?

AI scribes are now classified as AI as a Medical Device (AIaMD), requiring objective evidence of safety and effectiveness, continuous risk management, post-market surveillance and adverse event reporting. The black box nature of AI makes it hard to prove performance, manage ongoing risks and monitor real-world impact — creating major compliance challenges.

Clinical risk

The unpredictable outputs of black box AI increase the risk of medication errors, dosage mistakes and missed negations entering patient records.

Financial impact

Unvalidated AI outputs, driven by the black box problem, amplify the risk of clinical negligence claims — adding to the £5.1bn the NHS spends annually.

Regulatory risk

Black box AI makes demonstrating adherence to DCB0129/0160 standards extremely difficult, leading to potential regulatory breaches.

How CLEARvalidate works

The most rigorous AVT validation available to the NHS

More than just feedback. Tested on over 1,000 real-world consultations, with early predictive models achieving AUC > 0.7.

01

Audio quality check

DSP analysis

Analyses the sound quality. Noisy backgrounds generate poor notes — we check the recording is clear enough for accurate processing.

02

Speech clarity assessment

ASR analysis

Analyses the speech quality. A quiet background but poor speech quality impacts overall transcription even more.

03

Language and meaning analysis

NLP analysis

Analyses both meaning and lexical overlap with doctor-verified versions, ensuring the AI has understood the medical context correctly — not just the words.

04

Expert review and AI learning

LLM judge & human-in-the-loop

AI and medical experts work together to identify why errors occur and the significance of errors — understanding root causes so corrective measures are focused in the right areas.

05

Predictive error detection

ML models

Builds a smart system that predicts errors in real time, instantly flagging high-risk notes for review and preventing errors before they impact patient care.

Fully integrated solution — cost benefit

Based on published literature and CLEARnotes data, demonstrating significant efficiency and quality gains for a service handling 1,000 notes per month.

Current state
Every note requires full review: 4–5 minutes per note
Monthly burden: 67–83 hours
Cost: £5,360–£6,640 per month in clinician time
Risk: inconsistent review quality due to time pressure
With CLEARvalidate
Low risk (70%): 0.5 min spot check
Medium risk (25%): 2 min review
High risk (5%): 4 min detailed review
Total: 17.5 hours per month — a 74% reduction
Net impact
£47,520
saved annually (£3,960/month)
50 hours/month freed for patient care
Critical errors caught systematically
Healthcare team reviewing clinical data together
Deployment options

Two ways to deploy CLEARvalidate

OPTION 1

Retrospective validation

Weekly AI sample performance review
Comprehensive weekly analysis and reports of AI outputs and usage patterns to understand performance, adoption and clinical accuracy.
Identify where teams spend time editing AI-generated notes and uncover trends or risks requiring rapid mitigation.
Provide rapid and targeted support to improve outputs.
Benefits
Deep insights into real-world AI performance and accuracy
Identifies clinically significant issues early
Drives continuous improvement through updated usage policies, focused training and data-driven feedback for AI vendors
Builds organisational confidence in AVT safety and reliability
OPTION 2

Integrated validation

Real-time user feedback and site review
Validation embedded directly into clinical workflows — delivering live feedback on AI performance, accuracy and emerging issues.
User view: clinicians receive instant performance insights after each consultation, helping them assess accuracy and focus their reviews on the sections flagged.
Site view: aggregated dashboards give managers a live overview of usage, accuracy and emerging trends, enabling rapid intervention where needed.
