*Residence in private house or apartment only.
†Responses considered HCAP were all other residential statuses, with the exception of immunocompromised/immunosuppressed.
‡The proportions are calculated with respect to the total number of patients in which this score was reported to have been used to assess clinical stability.
CAP = community-acquired pneumonia; CURB-65 = Confusion, Urea nitrogen, Respiratory rate, Blood pressure, ≥ 65 years of age; HCAP = healthcare-associated pneumonia; PORT/PSI = Pneumonia Outcomes Research Team/Pneumonia Severity Index; SD = standard deviation; TCS = time to clinical stability.
