Abstract:

We estimated influenza- and RSV-associated hospitalizations using AHRQ State-Inpatient Data from the 1993-94 through the 2005-06 seasons using two different models. For the first model, age- and state-specific weekly respiratory and circulatory hospitalizations were fitted using negative binomial regression models that incorporated influenza and RSV viral surveillance data as covariates. For the second model, influenza and RSV ICD-9-coded hospitalizations were used as covariates. Models were compared in terms of estimates and model fit. The estimates and model fit were similar for both models. Persons aged 65 years or older had the highest influenza-associated hospitalization rate of 321 per 100,000 persons using the first model, followed by children younger than 1 year (152). Children younger than 1 year had the highest annual average RSV-associated hospitalization rate (2,431).
