Room: The Moscone Center: Poster Hall C
Background: The recent availability of molecular assays to detect multiple viruses in a single sample has led to increased detection of rhinovirus. The aim of this study is to describe the presentation and clinical course of hospitalized patients with a positive rhinovirus PCR from a respiratory specimen. 

Methods: Electronic medical records from adult inpatients with rhinovirus positive molecular testing from November 2009-October 2011 were retrospectively reviewed for patient characteristics, microbiology results, clinical course and in-hospital mortality. 

Results: One hundred forty-nine patients tested positive for rhinovirus. The mean age was 52 years (range 18-95). One hundred eight patients (72%) were admitted with a respiratory complaint. The most common presenting symptom was cough (58%), followed by tachypnea (48%) and fever (27%). In addition to rhinovirus, other viruses were isolated in 6 patients (4%): influenza A (2), human metapneumovirus (3), and parainfluenza 2 (1). Seventy patients (47%) were immunocompromised (hematologic malignancy, solid organ transplant, HIV, or receiving immunosuppressive drugs). Sixty-two (41%) experienced respiratory failure; ARDS developed in 22 (35%) of these. Pulmonary disease was significantly associated with respiratory failure, but being immunocompromised or obese was not (Table). Fourteen patients (22%) with respiratory failure died. The cause of death was listed as respiratory failure for eight (57%) of these.

Conclusion: Molecular assays allow for rapid detection of rhinovirus and other respiratory viruses. Rhinovirus is a cause of severe respiratory illness and respiratory failure in hospitalized adults. In this study, having pulmonary disease was associated with respiratory failure.
