Scientists Develop Rapid Susceptibility Tests for Urinary Tract Infections

In my geriatric patients, recurrent urinary tract infections and conditions mimicking them pop up frequently. Patients young and old find it inconvenient to come to the office to provide a specimen to analyze whether or not an infection has occurred and what is causing it. You often need to send the specimen off to the lab to culture the offending bacteria and then wait further for the lab to determine what antibiotic if any will work against that invader. As clinicians, if we suspect an infection and the in-office or clinic urine specimen looks infected, we treat with the antibiotics most likely to cure until we actually get the official reports back from the lab.

An esteemed panel of health care experts has recommended something different -suggesting that when symptoms of a urinary tract infection develop patients be prescribed a three day course of antibiotics without an exam or urinalysis or pre-antibiotic treatment urine for culture and sensitivity. This is all part of the 21st Century movement for less costly, less time consuming, more convenient self-diagnosis and care using your high tech apps to diagnose and treat your problem.

In my patient population many of the elderly patients use so many antibiotics so many times for presumed urine infections that we are often dealing with multi drug resistant bacteria requiring intravenous treatment with complex medications to cure the problem.

Scientists announced recently in the journal, Science Translational Medicine, that they have developed a rapid 30 minute DNA test that will allow us to determine the susceptibility of the offending organism quickly. The successful study has led to the beginning of developing a commercial variety of the test expected to be available in three years. If it works and is affordable it will make outpatient treatment of urinary tract infections far more accurate and efficient.
