A predictive tool for identification of SARS-CoV-2 PCR-negative emergency department patients using routine test results.
This retrospective case-control study investigated whether the use of a prediction tool based on complete blood count results and patient sex can better allocate testing for SARS-CoV-2 PCR testing in hospital emergency departments. Participants were emergency department patients who had concurrent complete blood counts and SARS-CoV-2 PCR testing in Northern California, Seattle, Washington, Chicago Illinois, and South Korea. A hypothetical scenario of 1000 patients requiring testing was developed, but in this scenario testing resources are limited to 60% of patients. This tool would allow a 33% increase in properly allocated resources.

Assessment of the accuracy of using ICD-9 diagnosis codes to identify pneumonia etiology in patients hospitalized with pneumonia.
Researchers assessed the validity of ICD-9 organism-specific administrative codes for pneumonia using microbiological data as the criterion standard, using data from 178 US hospitals in the Premier Healthcare Database. They found that, in this study, ICD-9 codes did not reliably capture pneumonia etiology identified by laboratory testing; because of the high specificities of ICD-9 codes, however, administrative data may be useful in identifying risk factors for resistant organisms. The low sensitivities of the diagnosis codes may limit the validity of organism-specific pneumonia prevalence estimates derived from administrative data.
