Here, with an article summarizing the findings here.  An excerpt from the latter:

Overall, 1140 (9.6%) infection preventionists responded. Almost 70% of respondents represented a healthcare system rather than a single facility, and facilities ranged from hospitals (42.7%) to ambulatory care (17.4%) and dialysis (2.7%). The centers, from all 50 states and Washington DC, ranged in size from those with 1 to 50 beds to those with more than 300 beds.

Of the respondents, 233 (20.4%) reported their facilities have no protective respirators and 317 (27.8%) said they were almost out of the devices, which are needed to protect healthcare workers managing patients with COVID-19 and different infectious diseases….

Other findings from the survey include:

• Nearly half of respondents (49.2%) said their centers lack sufficient enough face shields, with 36.5% reporting being almost out and 12.6% reporting being completely out.

• Approximately one third (31.7%) of respondents reported being completely or nearly out of face masks.

• Even simple hand sanitizer is in short supply at more than 1 in 4 facilities surveyed; 25.6% of respondents said they are almost out and 2.6% are completely out.

• Nearly 30% of respondents reported accessing supplemental PPE through state or local resources, while 24.6% said they accepted private donations of supplies.

• Fewer than one third (31.5%) said they had sufficient gowns.

• About 28% said they were almost out of protective respirators, while 20.5% said they have none.

• Only 12.3% said they have received supplies from federal resources, including the Strategic National Stockpile, which is controlled by the Department of Health and Human Services.

• 17.2% of respondents reported resorting to DIY measures such as sewing their own masks.

I guess I would not have expected dialysis and ambulatory care facilities (which makes up about 20% of the facilities included in the survey) to have respirators.  I haven't had time to look at the report to see whether it breaks down the data more thoroughly.
