“Our one-by-one real-time review of each patient has allowed us to offer quick help to clinical teams to ensure the right type of COVID-19 precautions for every patient, advise on testing and diagnostics, coordinate therapeutics, and enable surgeries/procedures to occur safely,” he said.

Jain also expressed thoughts on the ongoing recovery, saying that while the vaccination campaign so far is going “outstandingly,” much work is still needed to enable everyone to get their shots.

The doctor also expressed concern about patients in vulnerable communities and those who may have delayed seeking medical care for other needs during the pandemic.

“Concerning data abounds showing care that’s falling behind including delayed cancer, cardiovascular and other diagnoses,” Jain said. “Our med center has been and is extremely safe-we want all patients to come in for anything they need: we’re here for you and we want to connect with you.”
