Yousufuddin M, et al. - Given that patients hospitalized for pneumonia often have concurrent comorbid conditions (CCs), the researchers investigated the influence of CCs on the risk of subsequent death among adults hospitalized for pneumonia between 1996 through 2015 at Mayo Clinic. The presence of 20 priori selected CCs was examined among study participants. Using multivariable Cox regression model, cumulative all-cause mortality by the number of CCs was estimated. They reported that long-term mortality after hospitalization for pneumonia increases as the burden of comorbidities increases. In this manner, a simple comorbidity count help improves prognostic accuracy in identifying patients at increased risk of death following an episode of pneumonia.
