Practically 90 percent of COVID-19 patients who were put on ventilators in New York’s largest hospital system have actually passed away from the coronavirus, according to a study.

General, 88 percent of the clients treated at Northwell Health died after receiving mechanical ventilation, Dr. Safiya Richardson at the Feinstein Institutes for Medical Research and her associates found.

Of the 2,634 patients whose outcomes were known, 14 percent were dealt with in the intensive care unit, 12 percent were placed on ventilators and 3 percent received kidney replacement therapy, the research study said.

Twenty-one percent of the total group died, according to the findings, which were was released in the Journal of the American Medical Association.

The researchers studied the electronic health records of 5,700 patients with coronavirus disease hospitalized at Northwell Health, whose network consists of Lenox Hill on the Upper East Side, LIJ in Forest Hills and New Hyde Park, and the Staten Island University medical facilities.

The findings supported doctors’ conclusions that individuals who end up being badly ill with COVID-19 frequently have underlying medical concerns.

More than half, or 57 percent, had high blood pressure, 41 percent were obese and 34 percent suffered from diabetes, according to the study.

” Of the patients who passed away, those with diabetes were more likely to have gotten invasive mechanical ventilation or care in the ICU compared with those who did not have diabetes,” the researchers wrote.

The research study also confirmed that guys are most likely to die of the disease than ladies.

During triage, about a 3rd of all the patients, or 1,734, had a fever, about 17 percent had a high breathing rate and simply under 30 percent needed extra oxygen.

Typically, the patients were discharged after 4 days.

” This study reported death rates just for patients with definite results (discharge or death), and a longer-term study may find various death rates as various segments of the population are infected,” the researchers wrote.

The Feinstein Institutes for Medical Research is the research arm of Northwell Health.
