The primary claims‐based algorithms defined influenza as presence of an ICD‐10‐CM code for influenza, stratified by setting (inpatient/outpatient) and code position for inpatient encounters. Test characteristics and 95% confidence intervals (CIs) were calculated using test‐positive influenza as a ...

However, so far, no systematic review has summarized the available evidence on the effectiveness and safety of influenza vaccination in this patient group. Methods: We conducted a systematic review and meta-analysis and assessed the quality of evidence using the GRADE methodology. We searched MEDLINE...
The de-identified analytic sample included patients aged 18 years or older who were admitted to a hospital between July 2018 and May 2021 with an ICD-10 code for COVID-19 or influenza. Analyses were stratified by age and need for ventilation during acute hospitalization. Linear regression ...

Influenza A(H3N2) viruses predominated overall; however, influenza B viruses (primarily B Yamagata) emerged starting in March 2018 [2]. The overall vaccine effectiveness of the 2017–18 flu vaccine against both influenza A and B viruses was estimated to be 40% [2]. One factor that may ...
Pneumonia was defined as the presence of a CXR infiltrate and either an ICD-9-CM code or discharge summary diagnosis of pneumonia. Results Among 4,765 adults hospitalized with influenza, 1392 (29 %) had pneumonia. In multivariable analysis, factors associated with pneumonia included: age ≥...
To confirm the specificity of any observed differences, we examined motor vehicle collisions (ICD-10 V01-V79) as a condition where pH1N1 was not expected to have an impact. Data analysis Data analyses were conducted within each province. Frequent communication during the analysis stage ensured ...
