The article presents a study that examined the risk factors in seasonal differences in relation to hospital admission or due to seasonal variations in risk strata. It explores the predicted risk among hospitalized Medicare beneficiaries in seasonal variation for readmission of patients with cardiorespiratory conditions especially in winter months.
