“It’s just remained very busy, effectively, for the past two months or so,” said Dr. Jonathan Siner, the medical director at the hospital’s medical intensive care unit. New data from the U.S. Department of Health and Human Services shows the adult ICU occupancy rate at Yale New Haven Hospital currently stands at 87.9%. “Effectively, the ICUs are full even though the number says they’re not,” said Dr. Siner. The surge in ICU patients in the spring arrived and exited more rapidly but the situation is much different now, Dr. Siner said. “Everybody’s working very hard and I think people remain very focused. But there’s no doubt that everybody’s fairly tired."
