Virtual UTI Care Linked to Rising Antibiotic Use

TOPLINE:

Virtual visits for urinary tract infection (UTI) increased by more than 600% from 2015 to 2022, with overall UTI encounters growing by 325.9%. The rate of antibiotic dispensation climbed by 227.3% per 1000 patients, outpacing the 159.8% increase in positive urine cultures.

METHODOLOGY:

• Researchers conducted a retrospective cohort study analyzing 1,220,698 UTI encounters among 428,855 nonpregnant women aged ≥ 18 years at Kaiser Permanente Southern California from 2015 to 2022.
• Analysis included outpatient UTI encounters in ambulatory and urgent care settings, excluding emergency and inpatient visits.
• Data collection encompassed demographic information, urine tests, antibiotic dispensation, and UTI diagnoses using International Classification of Diseases, 9th and 10th Revision codes.
• Encounters conducted by physicians, physician assistants, nurse practitioners, and registered nurses through in-person, phone, video, and health portal platforms were evaluated.

TAKEAWAY:

• Virtual encounters grew by 603.2% compared with a 122.8% increase for in-person visits, with virtual visits accounting for 60% (733,263) of all UTI encounters.
• The rate of UTI encounters per 1000 adult female patients increased by 241.6%, while membership in the health system grew by only 24.4%.
• Antibiotics were prescribed without urine testing in 42.5% (519,135) of encounters, and among encounters with both antibiotic dispensation and urine testing, 57.1% (278,903) had a positive culture.
• According to the authors, the increasing rate of antibiotic dispensation surpassed the growth in positive urine culture rates, suggesting increased use of empiric antibiotics.

IN PRACTICE:

“Our findings underscore the importance of balancing telemedicine’s accessibility with maintaining antibiotic stewardship and highlight the need for updated guidelines,” wrote the authors of the study. An accompanying editorial said, “ Unfortunately, our misguided conceptual model has led to several decades of UTI research focusing on bad bugs rather than investigating the natural host defenses, how we might boost these, what perturbs the ecosystem, and how microbial defense occurs within the bladder.”

The study was led by Ghanshyam Yadav, MD, Kaiser Permanente Southern California in San Diego. It was published online in Obstetrics & Gynecology. The editorial, written by Nazema Y. Siddiqui, MD, MHSc, from the Department of Obstetrics and Gynecology, Duke University Medical Center, Durham, North Carolina, was also published in Obstetrics & Gynecology.

LIMITATIONS:

The retrospective design and analysis at the encounter level did not allow for control of patient and clinician clustering. The study was limited to a single health maintenance organization, which may affect the generalizability of the findings.
