Abstract
Background: Respiratory viral illnesses account for many hospitalizations and inappropriate antibiotic use. Respiratory viral panels by polymerase chain reaction (RVP-PCR) provide a reliable means of diagnosis. In 2015, the RVP-PCR assay at our institution was switched from respiratory viral panel (RVP) to rapid respiratory panel (rapid RP), which has a faster turnaround time (24 hours vs 12 hours, respectively). The purpose of this study was to evaluate the effect of RVP-PCR tests on duration of antibiotic use and length of stay (LOS) in hospitalized patients. Methods: We performed a retrospective chart review of patients who had a RVP-PCR ordered within a 1-year time period before and after the assay switch. Patients who were pregnant, had received antibiotics within 30 days prior to admission, were not discharged, or had not completed antibiotics by end of study period were excluded. Results: Data were obtained from a total of 140 patients (70 in each group). Of these, 25 (35.7%) in the RVP group and 28 (40.0%) in the rapid RP group had a positive result. The median LOS was 4.5 days (IQR, 3-9 days) in the RVP group and 5 days (IQR, 3-9 days) in the rapid RP group (P = .78). The median duration of antibiotic use was 4 days (IQR, 2-7 days) in the RVP group and 5 days (IQR, 1-7 days) in the rapid RP group (P = .8). Conclusion: Despite faster turnaround time, there was no significant difference in duration of antibiotic use, or LOS between the RVP and rapid RP groups.
