One way to find out this information is to search the want ads in your area. If they are constantly running ads, the nursing home might have trouble keeping staff members.
The Medicare website has an area under the Nursing Home Compare tab that displays the ratio of staff to patient; this isn't truly reflective of the number of nurses actually providing patient care. My book explains that nursing homes report every staff member who is in the facility, including the Director of Nursing, Assistant D.O.N., Staff Development Coordinator, MDS Coordinators, and nurses who perform other tasks.
The lesson that can be learned is that you never know what you're getting until you actually visit the nursing home. Visit several times - during dinner or breakfast is a good time, because the Administrator isn't in the building. Visiting when Adminstration isn't in the building allows you to see what is happening when Mom's not watching. - l.e.
