My mother is 90 years old and is in a nursing home. She is suffering from some dementia and is having reoccurring UTIs. After her dr. appointment today her doctor pulled me aside and started talking about some end-of-life decisions. He informed me that most deaths in the nursing homes come from UTIs and pneumonia. He believes that the UTIs my mother is suffering from will be what ends her life and he said this would be the time to continue to treat the UTIs, which would not resolve them and could possibly end her up in the hospital again or to stop treatment and allow her to slip away peacefully. Is this a common practice?
