Checks to detect urinary tract infections (UTI) typically are carried out routinely in hospitals, even when sufferers don’t have signs. Such testing “simply to be secure” can return outcomes that lead docs to prescribe antibiotics when there’s little to no proof to warrant such therapy.
Now, new analysis signifies that making a easy change to the digital system utilized by docs to order urine exams can reduce by almost half the variety of bacterial tradition exams ordered with out compromising the flexibility to determine individuals who want therapy for UTIs. The change encourages docs to first search for indicators of a UTI earlier than testing a affected person’s urine for micro organism.
The examine, by a group at Washington College College of Drugs in St. Louis, is printed Feb. 21 in An infection Management and Hospital Epidemiology.
“Over-testing for UTIs drives up health-care prices and results in pointless antibiotic use which spreads antibiotic resistance,” stated senior creator and infectious ailments specialist David Okay. Warren, MD, a professor of drugs. “Ordering exams when the affected person wants them is an effective factor. However ordering exams when it’s not indicated wastes sources and may topic sufferers to pointless therapy. We had been capable of scale back the variety of exams ordered considerably with out diminishing the standard of care in any respect, and at a considerable value financial savings.”

Micro organism in an individual’s bladder may cause UTIs, that are characterised by burning or ache whereas urinating, frequent urges to urinate and fever. UTIs are handled with antibiotics. However some individuals – typically aged individuals or these with diabetes – harbor innocent bacterial communities of their bladders that don’t have to be handled with antibiotics.
Earlier than ordering a urinalysis to examine for micro organism within the urine, infectious illness specialists suggest that physicians look first for indicators of bladder an infection utilizing a urine dipstick take a look at. This take a look at can detect inflammatory cells within the urine – indicators of a problematic UTI that will require therapy with antibiotics. Discovering micro organism rising within the urine with out realizing whether or not the affected person has indicators and signs of an infection leaves physicians unsure of whether or not the affected person will profit from antibiotic therapy.
“Medical doctors get caught with a end result they don’t know how one can interpret and sometimes prescribe antibiotics as a result of that looks as if the most secure path to take,” stated Warren, who’s the medical director for an infection prevention at Barnes-Jewish Hospital.
Warren, first creator Satish Munigala, MD, a knowledge analyst in an infection prevention, and colleagues made two modifications to encourage extra informative urine testing amongst their colleagues at Barnes-Jewish Hospital. First, they despatched an e mail to all clinicians explaining the rationale behind ordering a urine dipstick take a look at for indicators of an infection earlier than ordering a bacterial tradition take a look at. Then, they modified the digital ordering system. They set the default to a urine dipstick take a look at adopted by a bacterial tradition take a look at, somewhat than a tradition take a look at alone, which had beforehand been the primary possibility. Clinicians who wished to order a tradition take a look at alone may nonetheless accomplish that, however they needed to open an extra display screen on their computer systems.
The researchers in contrast all urine tradition exams ordered at Barnes-Jewish Hospital within the 15 months earlier than the intervention, staged in April 2016, to the 15 months after. Earlier than the intervention, docs ordered 15,746 urine cultures, or 38 orders per 1,000 patient-days. After, they ordered 45 % fewer: 8,823 whole, or 21 orders per 1,000 patient-days.
Particularly, the variety of urine cultures from individuals with catheters – who’re at excessive threat of UTIs – dropped from 7.8 to 1.9 per 1,000 patient-days whereas the variety of catheter-associated UTIs didn’t change in any respect. There have been 125 identified catheter-associated UTIs in every time interval.
“Everybody at all times worries that by ordering fewer urine cultures we’d miss some UTIs, however we confirmed that we didn’t,” Warren stated.
Because it prices about $15 to carry out a urine tradition, the intervention saved roughly $104,000 in laboratory prices alone over the 15-month interval. The researchers had been unable to acquire pharmacy data to find out whether or not extra cautious testing decreased antibiotic prescriptions, however earlier research have proven that minimizing unwarranted testing does scale back antibiotic overuse.
