Orders for standard/disposable masks are on long back-orders, due to both demand and supply chain issues.  Other hospitals across the country are reporting the same supply concerns.

While fabric masks are not to be used in the care of patients, according to the CDC, fabric masks are a crisis response option when other supplies have been exhausted. Fabric masks can also be helpful in other areas of patient care as supplies of PPE are depleted.  
 
“Prior to modern disposable masks, washable fabric masks were standard use for hospitals,” said Dawn Rogers, MSN, RN, FNP-C, Patient Safety & Infection Prevention Office.  “We will be able to sterilize these masks and use them repeatedly as needed.  While it’s less than ideal, we want to do our best to protect our staff and patients during this pandemic.”

Health Care Providers (HCP) use of homemade masks:
In settings where facemasks are not available, HCP might use homemade masks (e.g., bandana, scarf) for care of patients  as a last resort. However, homemade masks are not considered PPE, since their capability to protect HCP is unknown. Caution should be exercised when considering this option. Homemade masks should ideally be used in combination with a face shield that covers the entire front (that extends to the chin or below) and sides of the face.

"In high resource settings, disposable medical masks and respirators have long since replaced the use of cloth masks in hospitals. Yet cloth masks remain widely used globally, including in Asian countries, which have historically been affected by emerging infectious diseases, as well as in West Africa, in the context of shortages of personal protective equipment (PPE)"
