Ideas to stop patient from putting hands in toilet during their wiping.

person may flush between actual dumping then will wipe using the cold water in toilet while still sitting. Then pull up clothes and wipe hands on clothes then wash hands in sink. The wet hands from toilet gets on floor and nearby wall. The smell after each episode is so bad that I have to sanitize the bathroom each time after their use. Due to body functions we use pull ups and check them each time to ensure that they are clean. However some times I don’t check because of the anxiety level patient is exhibiting. I have thought about a bidet but know patient would not use it. Cognitive skills are not always good. She can still walk and talk but reasoning and decision making is not good.
