A new study examines how large language models perform in a variety of medical contexts, including real emergency room cases — where at least one model seemed to be more accurate than human doctors.
The study was published this week in Science and comes from a research team led by physicians and computer scientists at Harvard Medical School and Beth Israel Deaconess Medical Center. The researchers said they conducted a variety of experiments to measure how OpenAI’s models compared to human physicians.
In one experiment, researchers focused on 76 patients who came into the Beth Israel emergency room, comparing the diagnoses offered by two attending physicians to those generated by OpenAI’s o1 and 4o models. These diagnoses were assessed by two other attending physicians, who did not know which ones came from humans and which came from AI.
“At each diagnostic touchpoint, o1 either performed nominally better than or on par with the two attending physicians and 4o,” the study said, adding that the differences “were especially pronounced at the first diagnostic touchpoint (initial ER triage), where there is the least information available about the patient and the most urgency to make the correct decision.”
In Harvard Medical School’s press release about the study, the researchers emphasized that they did not “pre-process the data at all” — the AI models were presented with the same information that was available in the electronic medical records at the time of each diagnosis.
With that information, the o1 model managed to offer “the exact or very close diagnosis” in 67% of triage cases, compared to one physician who had the exact or close diagnosis 55% of the time, and to the other who hit the mark 50% of the time.
“We tested the AI model against virtually every benchmark, and it eclipsed both prior models and our physician baselines,” said Arjun Manrai, who heads an AI lab at Harvard Medical School and is one of the study’s lead authors, in the press release.
To be clear, the study didn’t claim that AI is ready to make real life-or-death decisions in the emergency room. Instead, it said the findings show an “urgent need for prospective trials to evaluate these technologies in real-world patient care settings.”
The researchers also noted that they only studied how models performed when provided with text-based information, and that “existing studies suggest that current foundation models are more limited in reasoning over nontext inputs.”
Adam Rodman, a Beth Israel doctor who’s also one of the study’s lead authors, warned the Guardian that there’s “no formal framework right now for accountability” around AI diagnoses, and that patients still “want humans to guide them through life or death decisions [and] to guide them through challenging treatment decisions”.
The Look Good and Have Hope Initiative, an impactful community project of CBrilliance, has successfully concluded in Jos, bringing free beauty and grooming services directly to communities across the city.
The initiative was held simultaneously at Tudun Wada Park, Islamiya Primary School along Bauchi Road, Bukuru Market, and AfrESH Center, providing beneficiaries with a range of complimentary services, including haircuts, hair making, manicures, and pedicures.
Beyond beauty and grooming, the initiative was about restoring confidence, promoting dignity, and reminding people that looking good can inspire hope and a renewed sense of self-worth.
Special commendation goes to the founder, Jethro Mark Da’ar, for championing this thoughtful initiative and creating a platform that allows people to look good, feel confident, and express themselves without financial barriers.
The successful conclusion of the Look Good and Have Hope Initiative further demonstrates CBrilliance’s commitment to community empowerment, social impact, dignity, and positive change.
When people feel good about themselves, they are better positioned to face the world with confidence and hope.
The Nigerian government has strengthened its partnership with China to expand cancer care through technology transfer, professional training, research and expansion of radiotherapy capacity.
The Minister of State for Health and Social Welfare, Iziaq Salako, disclosed this while delivering the opening address at the LINK Global Summit on Innovation and Practice in Oncology at the China National Convention Centre in Beijing, China.
This is according to a statement issued on Saturday and signed by Ado Bako, Assistant Director, Information and Public Relations, Federal Ministry of Health and Social Welfare.
The statement added that Nigeria also signed a strategic cooperation agreement with LinaTech, a Chinese company specialising in advanced radiation therapy solutions.
Cancer burden
Salako said cancer remained a national priority, noting that Nigeria recorded an estimated 127,763 new cancer cases and 79,542 deaths in 2022.
He said breast, prostate and cervical cancers accounted for more than 40 per cent of cancer mortality in the country.
According to the minister, Nigeria’s mortality-to-incidence ratio improved from 62.3 per cent in 2022 to 59.6 per cent in 2024, although he acknowledged that “significant work remained to be done.”
He said the government had, since May 2023, accelerated interventions across cancer prevention, awareness, early detection, treatment, financing, infrastructure, and research.
Salako cited the introduction of the Human Papillomavirus (HPV) vaccine into routine immunisation in October 2023, saying more than 14 million girls aged nine to 14 years had been reached.
He also mentioned the National Initiative for Cancer Early Detection, Screening and Coordinated Access to Network Care (NICE-SCAN), as well as initiatives of the Task Force for the Elimination of Cervical Cancer, as part of efforts to improve early detection and referral.
Nigerian govt partners China to expand radiotherapy capacity
China partnership
The minister said the emerging partnership with China would provide technical assistance in radiotherapy, support joint research and development, facilitate academic exchanges, and build professional capacity.
He said Nigeria was a founding African partner of the LINK Global Oncology Alliance and had also participated in the inauguration of the Radiotherapy Working Group of the China-Africa Hospital Alliance.
Salako said Nigeria wanted the cooperation agreement to result in a joint work plan with designated focal persons and quarterly milestones.
“We want to see the twinning of our cancer centres of excellence, the National Institute for Cancer Research and Treatment(NICRAT), and our tertiary hospitals like the National Hospital, Abuja, with the Chinese cancer hospitals,” he said.
He also called for the establishment of a designated clinical training base in Nigeria to serve as a West African hub for advanced radiotherapy training.
He said Nigerian radiation oncologists, medical physicists, radiotherapy technologists and biomedical engineers should also have opportunities for fellowship training in China.
Beyond equipment
Salako said Nigeria’s long-term objective was not simply to acquire cancer equipment but to develop the technical and human capacity required to install, maintain and eventually manufacture cancer technologies locally.
“Machines without people are monuments,” he said, stressing that trained personnel, maintenance systems and sustainable technical support must back every linear accelerator installed.
He said Nigeria would also pursue technology transfer, local assembly and servicing of radiotherapy and imaging equipment, joint clinical trials, cancer registry-linked research, artificial intelligence-assisted treatment planning, adaptive radiotherapy and tele-oncology collaborations by 2030.
The minister said the government’s incentives for health manufacturing, including zero-duty and zero-VAT measures, provided an enabling environment for investment in local production and technology transfer.
Cancer treatment, research
Mr Salako said six cancer centres of excellence were being developed, with three already completed and commissioned in Katsina, Enugu and Benin.
He said the centres were equipped with modern linear accelerators, while work on the remaining three was progressing.
He also disclosed that President Bola Tinubu had approved the procurement and installation of 35 additional linear accelerators between 2026 and 2028 to expand access to radiotherapy further.
The minister said the government had also strengthened NICRAT, which had trained about 140 early-career cancer scientists and supported 24 research grants.
He identified the National Cancer Access Programme, Catastrophic Health Insurance Scheme, National Cancer Health Fund, and Social Determinants of Cancer Care Fund as mechanisms to improve access to cancer medicines and care while alleviating the financial burden on patients and families.
Salako said the interventions were being implemented under the Nigeria National Cancer Control Plan 2026–2030, which prioritises prevention, decentralised diagnosis and treatment, financial risk protection, oncology workforce development, clinical trials and cancer registries.
He also mentioned the recent inauguration of the Blood Cancer Consortium as part of efforts to enhance coordination in the national cancer-control response.
He stated that the government aimed for the China partnership to help translate oncology innovations into tangible improvements in patient care.
“Innovation in oncology is meaningful only where it reaches the patient. Let this summit be remembered not for what was displayed, but for what was delivered. Nigeria is ready, our plan is costed, our partners are welcome, and the patients are waiting,” he said.
