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”.

Just-In: Abduljabar Adama Keeps Nigeria’s Hopes Alive, Storms Into Commonwealth Games 50m Freestyle Semi-Finals

Nigeria’s Abduljabar Adama kept the country’s swimming hopes alive on Day Two of the Glasgow 2026 Commonwealth Games, producing an impressive performance to qualify for the men’s 50m freestyle semi-finals at the Tollcross International Swimming Centre.

Competing in a highly competitive Heat 7, Adama rose to the occasion against a quality field that included Australia’s Flynn Southam, England’s Jacob Mills, Canada’s Antoine Sauvé, and Northern Ireland’s Matthew Hamilton. The Nigerian sprint swimmer finished strongly to secure one of the qualifying places for the semi-finals, becoming Nigeria’s lone representative in the next stage of the event.

It was, however, a disappointing outing for compatriot Clinton Opute, who competed in Heat 8 alongside Australia’s Jamie Jack, South Africa’s Michael Houlie, The Bahamas’ Lamar Taylor, and Fiji’s Hansel McCaig. Despite a determined effort, Opute’s time was not enough to earn one of the coveted semi-final spots, bringing his campaign in the event to an end.

Adama’s qualification is another significant milestone in his rapidly developing career. The young Nigerian has earned a reputation as one of Africa’s brightest sprint prospects after setting the African junior record in the 50m freestyle, and his latest performance reinforces his growing status on the international stage.

Sports247, reporting from Glasgow, observed jubilant celebrations from the Nigerian camp after Adama’s qualification was confirmed. With the semi-finals scheduled later on Day Two, the Nigerian will now aim to produce another explosive swim as he targets a historic place in the Commonwealth Games final.

After Team Nigeria’s outstanding medal haul in para powerlifting on the opening day, Adama’s progression provides another positive storyline for the Nigerian contingent as the Games gather momentum in Glasgow.

Abuja-bound Aero Contractors flight makes emergency return to Lagos over ‘technical issue’

An Aero Contractors flight travelling from Lagos to Abuja on Saturday morning returned to its departure airport after the crew reported a technical issue while the aircraft was airborne.

The aircraft, which departed Lagos at about 7:30 a.m., had travelled part of the route mid air before the flight crew decided to discontinue the journey and return to Lagos as a precautionary safety measure.

Passengers were safely evacuated after the aircraft landed, and no injuries were reported.

A passenger aboard the flight told PREMIUM TIMES that the cabin became unusually hot while the aircraft was in the air, causing anxiety among passengers.

According to the passenger, the crew informed those on board that the aircraft had developed a technical problem and would return to Lagos but did not disclose the exact nature of the fault.

“There was a lot of panic because people did not know exactly what had happened. We were only told there was a technical problem and that we had to return to Lagos,” the passenger said.

As of 10:10 a.m., the affected passengers had begun boarding another Aero Contractors aircraft to continue their journey to Abuja, according to one of the passengers who spoke with PREMIUM TIMES.

PREMIUM TIMES contacted Aero Contractors for comments on the incident, including the nature of the reported technical issue, the reason for the aircraft’s return to Lagos and the arrangements made for affected passengers.

However, the airline had yet to respond as of the time this report was filed.

Recent incidents

Saturday’s occurrence comes about two months after a Max Air flight from Abuja to Katsina made an emergency return to the Nnamdi Azikiwe International Airport shortly after take-off following a reported technical fault.

As previously reported by PREMIUM TIMES, passengers on the May 2026 flight recounted hearing loud banging sounds from the aircraft before it reportedly lost altitude briefly and struggled to stabilise, prompting the pilot to return to Abuja as a safety precaution. The aircraft landed safely, and no injuries were reported.

The Aero Contractors incident also comes amid increased public attention to airline operations following Thursday’s runway excursion involving an Enugu Air Embraer E170 at Benin Airport.

Although all 63 passengers and five crew members escaped unhurt, the occurrence disrupted flight operations after the runway was temporarily closed, forcing Air Peace and United Nigeria Airlines to suspend flights to and from Benin while aircraft recovery and safety assessments were carried out.

While the circumstances surrounding the Aero Contractors, Max Air and Enugu Air incidents differ, they have renewed attention on operational reliability and safety across Nigeria’s aviation sector.
