7Million waiting

More than seven million patients sit on the NHS waiting list in England, alongside around 100,000 staff vacancies. The queue is not a side effect of the system; in places it is the rationing mechanism.

The queue is the system

3 in 4 patients surveyed say they have waited too long to see a specialist, with their longest wait averaging 56 days.

WSJ paid programme (sponsor survey), 2025

Paperwork eats the hours

Physicians spend nearly two hours on electronic health records for every hour of direct patient care, much of it after the clinic closes.

Vaid et al. (Univ. of Alberta), 2026

Patients go around it

About one in six adults (17%) already ask AI chatbots for health information and advice at least once a month.

01 / What earlier access buys

Seen sooner, treated cheaper

Diagnosis, detection, decision support and drug discovery: the gains the research can put a number on.

Q1 · Diagnostic accuracy
80%
On complex cases, against 20% for physicians alone

Microsoft's MAI-DxO, paired with OpenAI's o3, reached 80% diagnostic accuracy on complex case records, four times the 20% average of generalist physicians on the same cases.

Nori et al. (Microsoft AI), 2025

Company-reported
Q2 · Detection
0.435
F1 detecting pneumonia, against 0.387 for radiologists

CheXNet, a deep-learning model reading chest X-rays, scored an F1 of 0.435 for pneumonia against a 0.387 average for four practising radiologists on the same images.

Q3 · Remote diagnosis
28/32
Specialist-rated axes where AI beat physicians by text

In a blinded text-chat consultation study, Google's AMIE outperformed primary-care physicians on 28 of 32 axes rated by specialists and 24 of 26 rated by patient actors.

Tu et al. (Google), 2024

Company-reported
Q4 · Outcomes
16%
Fewer diagnostic errors with AI decision support

Across 39,849 patient visits in 15 Nairobi primary-care clinics, clinicians with an AI decision-support tool made 16% fewer diagnostic errors and 13% fewer treatment errors.

Korom et al. (Penda Health / OpenAI), 2025

Company-reported
Q5 · Drug discovery
30days
From target selection to a first hit molecule

Using AlphaFold-predicted structures in an AI drug-discovery pipeline, researchers found a hit compound for a novel cancer target within 30 days, after synthesising only 7 compounds.

Q1 · Throughput
9.5%
Less documentation time with AI scribes

A randomised trial of 238 physicians across 72,000 encounters found ambient AI scribes cut documentation time by up to 9.5% and improved burnout scores.

Lukac et al. 2025, cited in Karbalaie et al., 2026

Peer-reviewed
Q2 · Equity
48
Narrowing of the white–Asian health-benefit gap

Including ethnicity in a diabetes-risk model, rather than excluding it, narrowed the net-benefit gap between the most and least benefited groups (white and Asian) by 48 (95% CI 32–66).

Q4 · Early flagging
0.87AUC
Detecting acute heart failure on chest CT

An interpretable model flagged radiological signs of acute heart failure on chest CT with a test AUC of 0.87, potentially before the formal radiology report is written.

Ørting et al. (Univ. of Copenhagen), 2025

Single-source
No verified statistic

No verified figure exists for how many earlier diagnoses changed the treatment actually given. Systems record when a diagnosis was made, not what would have happened without it.

No verified statistic

Nobody publishes the share of remote consultations that ended in an in-person visit anyway. The systems that hold the data do not release it.

02 / Emerging & unsettled

Directional, not settled

Skewed data, gains at scale, open-source tools and the thin evidence on what any of it costs.

Q10 · Who is in the data

Q4 · At scale
22,000
Visits a year where AI would avert a diagnostic error

Applied across Penda Health's clinics, the AI tool would avert diagnostic errors in about 22,000 visits and treatment errors in 29,000 visits a year.

Q5 · Cost per case
$2,397
For 79.9% accuracy, against $7,850 for 78.6%

The same diagnostic accuracy can cost very different amounts: orchestrated MAI-DxO reached 79.9% at $2,397 a case, where off-the-shelf o3 reached 78.6% at $7,850.

Company-reported
Q5 · Cost evidence
6of 66 usable
Of 66 studies of AI's economic impact usable for analysis

A systematic review of AI's economic impact in health care could take only 6 of 66 publications forward, and none of those had a complete cost-impact analysis.

Wolff et al., J Med Internet Res, 2020

Peer-reviewed
No verified statistic

The effect of pooled booking on clinician retention is unmeasured. Systems reporting fewer vacancies over the same period cannot separate booking policy from pay settlements.

No verified statistic

No source puts a national figure on what a wait costs patients: time off work, childcare, travel. Small surveys exist; none are comparable.

03 / What the wait costs

The wait is a treatment

Bias in triage, errors in the notes, misinformation on request and tools priced beyond reach.

Q6 · Gender bias
43.8%
Of triage decisions flipped by changing gender alone

Swapping only the patient's gender in otherwise identical emergency vignettes flipped a model's triage level up to 43.8% of the time; all five models tested exceeded the pre-registered 5% threshold.

Young et al. (EQUITRIAGE), 2026

Single-source
Q9 · Scribe errors
18.5%
Of flagged AI-scribe safety issues were medication errors

In feedback on 50,123 AI-scribed encounters, the largest category of safety issues, 18.5%, was medication names, doses or instructions recorded wrongly.

Dai et al. (UC Berkeley / UCSF), 2025

False health answers when told to lie, four of five chatbots

Instructed to give false health answers with fabricated references, four of five leading chatbots did so 100% of the time; only Claude refused more than half the time.

Peer-reviewed
Q5 · Adoption cost
$600
A month per physician for commercial AI scribes, at the top

Commercial AI scribes cost $99 to $600 per physician per month, out of reach for rural clinics, safety-net systems and lower-income countries.

Q6 · Projected harm
110,000
Extra lower-severity triage calls for women a year (France)

Applied mechanically to France's 20.9 million annual emergency visits, a 1.1% gender differential in triage would mean on the order of 110,000 more lower-severity assignments for women a year (illustrative range 90,000–130,000).

Guerra-Adames et al., 2025

Q9 · Readmissions
$17.9bn
Yearly cost of hospital readmissions, 76% avoidable

One estimate puts the burden of hospital readmission at $17.9 billion a year, with 76% of readmissions avoidable: the strain risk-prediction tools target.

04 / What nobody measures

Unreported is not zero

Wide cost ranges, models that comply with bad instructions and risks no one has yet sized.

Q5 · Cost per case
$4,000–7,900
Diagnostic test cost per case for top off-the-shelf models

Off-the-shelf models that reached 70–79% accuracy did so by ordering extensive tests, at $4,000 to $7,900 a case. Physicians on the same benchmark averaged $2,963 a case at 20% accuracy.

Q9 · Absolute risk
50,123
AI-scribed encounters reviewed, with risk still unsized

Feedback on 50,123 encounters from 470 physicians points to real safety risks in AI scribes, especially around medication, yet the authors say the absolute degree of risk still needs study.

Dai et al. (UC Berkeley / UCSF), 2025

Single-source
Q6 · Threshold
5 of 5
Models tested that broke a 5% fairness threshold

All five models audited, across 374,275 evaluations on 18,714 vignettes, changed triage levels by gender more often than the pre-registered 5% limit.

Q8 · Updates
~25%
Of FDA-cleared AI devices reporting new features

Nearly a quarter of FDA-cleared AI devices report updates in the form of new features or claims, but almost none report retraining, so how they change after approval is largely unseen.

Who decides what a wait is worth?

Both sides of this page are measured to the same standard and given the same weight. Every figure carries a source and a confidence label; where none existed, the page says so instead of estimating. The trade-off is real; what it should cost a patient is not a number this research can supply.
