Respiratory viral testing in hospitalized patients is thought to improve quality of care by reducing the use of diagnostic tests, guiding infection control precautions, and rationalizing antimicrobial therapies. Few small published studies have tested these assumptions, and have demonstrated conflicting results.
We conducted a retrospective cohort study of 24,567 hospitalizations using administrative data to determine the associations between viral testing, patient outcomes, and process of care.
Viral testing was not associated with improved mortality or length of stay in hospital, and resulted in more resource utilization. The test result did not influence the duration of isolation precautions. This implies that health care providers may not use the results of testing in making management decisions, or in guiding the use of isolation precautions. This study provides the foundation for further scientific evaluation and reform of our current respiratory infection control policy.
