Observational longitudinal study of symptom burden and time for recovery from community-acquired pneumonia reported by older adults surveyed nationwide using the CAP Burden of Illness Questionnaire.

In the subgroup with COPD, the younger group took longer to return to their baseline COPD condition than the older age group ( P =0.004), as did hospitalized participants compared to nonhospitalized participants ( P =0.025), although these differences did not reach statistical significance when adjusted for multiplicity ( P <0.003).
