ChatGPT prompted to generate 80% of 100 false narratives tested by NewsGuard
In January 2023, NewsGuard analysts tested OpenAI's ChatGPT by providing 100 leading prompts based on false narratives from its Misinformation Fingerprints database. ChatGPT generated eloquent, false or misleading claims for 80 of the 100 prompts, including content about COVID-19 vaccines, ivermectin as a treatment, and the Parkland school shooting conspiracy theories. ChatGPT sometimes included qualifying statements or refused certain prompts, but in most cases bad actors could easily delete such disclaimers. OpenAI did not respond to NewsGuard's requests for comment at the time.

UnitedHealth used ALERT algorithm to limit mental health coverage, regulators found
ProPublica reports that UnitedHealth Group's Optum subsidiary used the ALERT algorithm to flag mental health patients and therapists as outliers, leading to therapy coverage denials. Regulators in California, Massachusetts and New York alleged this breached the federal Mental Health Parity and Addiction Equity Act, and UnitedHealth agreed to restrict the system in those jurisdictions. The company denies wrongdoing and says its programmes are compliant. Affected patients, including Medicaid enrollees, were left to pay out-of-pocket or go without care.

NHS liver transplant algorithm causes longer waits for younger patients
An NHS computer algorithm that prioritises liver transplant patients most likely to die soon has led to younger patients waiting 156 days longer on average than those over 60. The algorithm, launched in 2018, gives a score based on 21 recipient and seven donor parameters. Patients like Sarah Meredith, 31, have been waiting two years for a transplant. NHS Blood and Transplant defends the system as saving lives but acknowledges the stress on younger patients.

NHS QCovid algorithm incorrectly labels young patients as high risk, causing vaccine call-up
The article reports that scientists are questioning the reliability of the QCovid risk prediction algorithm used by the NHS to prioritise COVID-19 vaccinations. Due to missing data on weight or ethnicity, the algorithm automatically assigns a high BMI and high-risk ethnicity, leading to young, healthy patients being incorrectly labelled as high risk and called for early vaccination. GPs have identified hundreds of such cases, causing anxiety and potentially delaying vaccinations for more vulnerable individuals. NHS Digital acknowledged the issue and said clinicians can remove patients from the shielding list.

Four commercial large language models perpetuate race-based medical misconceptions
A study published in npj Digital Medicine tested four commercial large language models (Bard, ChatGPT, GPT-4, and Claude) for their tendency to propagate discredited race-based medical beliefs. When asked about kidney function, lung capacity, and skin thickness, the models sometimes endorsed debunked racial differences, particularly affecting Black patients. The study concludes that these biases pose a potential hazard and urges caution before using such models in clinical decision-making.

Immigration NZ uses data model to predict likely troublemakers among overstayers
Immigration New Zealand has been piloting a data modelling system that uses demographic information such as age, gender, and ethnicity of overstayers to predict which individuals are likely to commit crime or incur hospital debts. The system then targets those individuals for accelerated deportation. Critics, including immigration lawyers and a lobby group, have likened the programme to 'Minority Report' and allege it amounts to racial profiling. Immigration Minister Iain Lees-Galloway only learned of the programme on the day of the article and said he would seek a full briefing, but maintained it is not racial profiling and does not breach the Human Rights Act.

UNOS liver allocation policy reduces transplants in poorer states
The United Network for Organ Sharing (UNOS) implemented a new liver allocation policy in 2020 called the acuity circles system, which prioritizes the sickest patients regardless of location. An analysis by The Markup and The Washington Post found that the policy led to sharp declines in liver transplants in several Southern and Midwestern states and Puerto Rico, while increasing transplants in New York and California. Patients in affected states allege the system disadvantages poorer regions, and hospitals have sued to overturn the policy.

DWP algorithm approved Kickstart gateways with no trading history or based abroad
An FE Week investigation found that the Department for Work and Pensions (DWP) approved dozens of companies as Kickstart gateways through automated due diligence checks using the Cabinet Office Spotlight Tool, although some had little or no trading history or were based abroad. The DWP said gateways were subject to stringent checks and later said human checks were also used. After the findings were shared with the Treasury and the DWP, the department stopped taking gateway applications and scrapped the requirement for small employers to use gateways from 3 February.
