Other things like triple diapering to not have to change the elder more than 1x per shift and massive yeast infections underneath the breasts due to lack of bathing and not changing clothes.
The worst types of places I have seen are the "board and care" facilities for mentally disabled adults run by Russians in the east bay. There were a few rotted/unchanged/septic g-tubes that were absolutely horrific. It's been years and that specific smell of a rotting gtube is still burned into my brain.
There was also this case in the East Bay where the facility abruptly shut down and stopped paying their workers and so all the caregiving staff just left except for the janitor and the cook who stayed on and cared for the seniors for several days until the fire department and sheriff finally responded: http://www.npr.org/2014/11/21/365433685/if-we-left-they-woul... <--- Honor should give those two dudes who stayed jobs!
It's a very challenging industry.
