Doctor will not test for urine infections until elderly woman has fever.This is because she gets infections frequently. We know when there is blood, mucous and cloudiness in the catheter tube that she is in trouble, but doctor says she colonizes bacteria in her bladder, so they won't let Home Health nurse test until there is a fever. We have to wait for them to get order from doctor, come over to Mom's house for UA sample, then get it to lab and wait for them to test and get back to doctor. Last three times this happened, she was so sick (102 degree fever, hallucinating) that we had to rush her to emergency room for treatment. The right antibiotic does cure the problem quickly. We do everything we can to prevent these infections - lots of water, cranberry tablets, probiotics, sanitary procedures when we empty and clean around the catheter (we have trained caregivers) Doctor says that since she colonizes bacteria in her bladder due to catheter, they will not test until there is fever and/or pain. Mom will not tell us when she hurts! Can't change doctors easily since this one will let us call anytime and give us advice or prescribe over the phone so we avoid the hassle of getting her into the office. She is 104 years old!
