With a second wave of COVID-19 cases expected to hit Minnesota hospitals in coming weeks, the state has millions of medical-grade N95 respirator masks on order for health care workers treating coronavirus patients.
So far about 337,000 of these critical masks have been delivered to the state stockpile since March, while orders for more than 5 million more are still awaiting delivery. A review of the state's purchasing shows those masks will arrive in batches over the next year and a half. Some may never arrive at all.
"This is a make-sure-we're-turning-over-every-stone approach," said Wayne Waslaski, project manager for the Minnesota Department of Public Safety's critical care supplies team. "The normal supply chain isn't working."
In a topsy-turvy global mask market, the Minnesota Department of Health warehouse in St. Paul has been able to secure just three batches of more than 100,000 medical-grade infection-preventing N95 masks since March, including two made by Maplewood-based 3M Co. These state stockpile masks serve as a backup supply for hospitals, which have about 745,000 N95s in storage today, state data show.
N95 respirators are tightfitting masks that filter out 95% of particles 0.3 microns wide, including those carrying the SARS-CoV-2 virus. They're one of the cheapest and most widely used methods to make sure doctors, nurses and lab workers can safely breathe the same air as COVID-19 patients.
Minnesota hospitals consume about 9,000 medical-grade N95 masks per day. However, nurses are wearing single-use masks for as many as five days at a time to lower their daily burn rate, going against their training. Health care workers in the state use another 67,000 nonmedical-grade masks per day, including some N95s, and also KN95 masks made under Chinese standards.
After months of vetting by the state, just two companies have been able to deliver the sought-after respirators to Minnesota: Texas-based McKesson Corp., which has filled two orders for 3M respirators, and Bloomington's Donaldson Co., which has delivered one batch of high-filtration N99 respirators and a second batch of nonmedical-grade masks.
Donaldson is still trying to get government approval to import another 500,000 N95s. The most recent delivery of medical-grade respirators to the state came last Monday, when 114,840 3M N95s arrived from McKesson. That's part of an order for 3 million, which will arrive in monthly shipments through 2021.
