In Harvard study, AI offered more accurate diagnoses than emergency room doctors

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”.

Imo senatorial aspirant, Nwachukwu drags NDC to court over ticket denial

A Senatorial Aspirant, Isaac Nwachukwu, has dragged Nigeria Democratic Congress, NDC, and the Independent National Electoral Commission, INEC, before a Federal High Court Sitting in Owerri, Imo State, over the fallout of the party’s National Assembly primaries.

Nwachukwu, in a suit filed through his Counsel, Cajethan Oguzie, accused the party of denying him the Imo North senatorial ticket after emerging a consensus candidate and paying N5m for the nomination form.

The suit also disclosed that Nwachukwu had paid N20m for the support of the party, but his support was unexplainably reduced to N10m when the list of those who supported the party was published.

The NDC Senatorial Aspirant, in his prayers before the court, demanded that a declaration should be made that he is the consensus candidate of the party in the state with regard to the Imo North Senatorial Zone in the 2027 General election.

“A declaration that the first defendant, NDC, be restrained from fielding another candidate except the plaintiff in the General election into the Imo North Senatorial Zone as he is the consensus candidate for the said election.

“A declaration that the second defendant, INEC, be perpetually restrained from recognising and accepting the candidacy of another person except the plaintiff in the Imo North Senatorial election pending the determination of the matter,” the suit stated.

In an affidavit supporting the originating summons, Nwachukwu stated that he purchased the expression of interest form to aspire for the position for Imo North senatorial zone, a copy of which is attached in the suit already filed.

The NDC Senatorial Aspirant added that upon the purchase of the form, he made a monetary contribution in support of the party’s growth in the tune of N20m into the party’s FCMB account number through his Counsel, receipt also attached in the suit as an exhibit.

“The first sign of irregularity and no compliance with the NDC constitution and electoral act came up when the N20m I paid for party support was allocated to one of the aspirants for my Senatorial District by the name Matthew Omegara, and the N10m that Matthew Omegara paid for party support was allocated to me by the Screening Committee headed by Sam Egwu and Buba Galadimma.

” In compliance with NDC’s directives, I participated in the NDC screening exercise and was successfully cleared as an aspirant to participate in the primary election.

After my consensus candidacy was ratified, my name was shortlisted as a Candidate for Imo North district. A copy of the result is hereby annexed as Exhibit 1U5,” the affidavit added.

Nwachukwu alleged that his name was substituted with Omegara after he had been declared the winner of the primary election.

The Imo North Senatorial Aspirant claimed that the National leader of the party, Seriake Dickson, had summoned him for a meeting telling him that his candidacy was affected after a party chieftain from his state said he didn’t know him.

Among other demands, Nwachukwu is asking the court to order NDC to issue him a certificate as its candidate for the Imo North Senatorial District.

Supporters and members of the African Democratic Congress, ADC, in Anka and Talata Mafara Local Government Areas of Zamfara State have alleged attempts to manipulate the party’s membership records and card numbers ahead of internal political activities.
The allegation was contained in a statement issued on Wednesday in Gusau by Nura Rabiu Cibiki, Director of Media and Strategy, Campaign and Mobilisation Committee for Abdulrahaman Yahaya, an aspirant for the House of Representatives seat representing Anka/Talata Mafara Federal Constituency.

The group warned against any attempt to alter or duplicate legitimate membership figures, saying such actions could deepen tensions within the party in the constituency.

“We strongly oppose any move to manipulate or duplicate legitimate membership figures, warning that such actions would only worsen existing tensions within the party and the Anka/Talata Mafara Federal Constituency,” the statement said.

The supporters maintained that ADC members in Anka and Talata Mafara were aware of the party’s authentic membership strength and were prepared to protect the integrity of the party’s records.

The statement added that while justice may be delayed, the truth could not be denied.

Meanwhile, Yahaya has filed a suit at the Federal High Court in Gusau challenging alleged irregularities in the party’s primary election process in the constituency.

The court has fixed June 23, 2026, for mention of the case.
