Third-party vendor physicians appear to be more much more likely than their system-employed counterparts to prescribe antibiotics during acute care telehealth visits for acute respiratory infection (ARI), according to a study in the Journal of Telemedicine and Telecare.
As health systems expand their direct-to-consumer (DTC) virtual care, the quality of that care seems to vary, write the authors. Patients with ARI symptoms make up about one-third of virtual visits. Prescribing practice is a commonly cited measure of care quality for ARI, which is usually viral and rarely benefits from antibiotics.
“When providing care through telehealth, hospital-affiliated emergency physicians practiced better antibiotic stewardship than vendor-supplied, non–hospital-affiliated physicians,” lead study author Kathleen Li, MD, MS, a clinical lecturer in the department of emergency medicine at the University of Michigan, Ann Arbor, told this news organization.
“We had a sense that a difference existed, but the magnitude of the difference was larger than expected,” she said.
Dr. Li and her colleagues retrospectively analyzed on-demand telehealth visits available to health system employees and dependents of a large urban academic health system from March 2018, when the service began, through July 2019.
All 16 affiliated physicians providing ARI care were board-certified in emergency medicine, compared with 2 (8%) of the 25 unaffiliated (vendor-employed) physicians. Most unaffiliated physicians were known to be board-certified in family medicine, internal medicine, or pediatrics.
Unaffiliated physicians were not given access to the health system’s electronic medical record. Instead, all their patient histories, exams, assessments, plans, impressions, and discharge instructions were scanned into the electronic medical record system by other staff the next day.
Unaffiliated doctors were more than twice as likely to prescribe antibiotics
The researchers extracted data on all 257 virtual ARI visits from the electronic health record system, including prescriptions and medication therapeutic class. They performed multivariable logistic regression, adjusting for patient age and time of visit (weekday vs. weekend; day vs. overnight).
Antibiotic prescription rates were similar between weekday and weekend visits, and between day and night visits. Regardless of provider status, older patients were more likely to be prescribed antibiotics (P = .01).
Overall, affiliated physicians prescribed antibiotics during 18% of visits, whereas vendor physicians prescribed antibiotics during 37% of visits. After adjustments, the odds were 2.3 times higher that a patient in a telehealth visit with a vendor provider would be prescribed antibiotics (95% confidence interval, 1.1-4.5).
The predicted antibiotic prescribing rate for ARI was 19% (95% confidence interval, 13%-25%) for affiliated providers vs. 35% (95% CI, 22%-47%) for unaffiliated providers, an average marginal effect of 15% (95% CI, 2%-29%). The difference was even greater (average marginal effect 20%, 95% CI, 4%-35%) when children and patients over 65 were excluded.
Consistent, high-quality care and antibiotic stewardship are needed in all settings
Three experts who were not involved in the study commented on the study.
Joshua W. Elder, MD, MPH, MHS, medical director of Telehealth Express Care (direct-to-consumer telemedicine) at UC Davis Health in Sacramento, Calif., said, “An important unanswered question is how factors such as communication (policy and procedures, practice guidelines), connection (electronic health records), and reimbursement and incentives that health system and vendor-based providers received impacted this outcome.
