This is super cool! UTI's are a major problem in the eldery community as well. While I don't have vetted data, I do have my day-to-day experience working in the Fire/EMS industry as a first responder.

I had a patient yesterday, 77 y/o female that was initially called in for erratic behavior. Right when I got in the truck I had a suspicion this was a UTI based on the address, care home, and the comments on the MDT. While UTI's don't always present with a fever, this one did and the care taker knew enough to not flush the toilet... Yes sir, I was 99.999% sure it was a UTI. However....

I had to call a BLS ambulance to take her to the ER because we don't transport to urgent care. The costs associated with this UTI will be in the thousands. I hope we could carry your kit on our fire engines and ambulances as it would reduce unnecessary visits to the ER and the burden on our EMS system.
