Age-related differences in patient-reported quality of care among adult German patients with bronchial asthma: a cross-sectional study

Limited evidence exists on age-related differences in health-related quality of life (HRQoL) and patient-reported outcome and experience measures (PROMs/PREMs) among asthma patients. This study analysed data from 765 adults in the German PROMchronic trial, comparing generic HRQoL, asthma-control, and PREMs across age groups (18-44, 45-64, 65-74, ≥75 years), with analyses stratified by gender. Older adults, particularly women aged 65-74 years, reported slightly higher HRQoL (p = 0.004, η² = 0.017), and ≥75 aged reported better asthma control scores (p = 0.012, Cliffs Delta = 0.261). Categorical asthma control and most PREM domains did not differ significantly. Organisational aspects of care were rated more favourably by adults aged 65-74 years (p = 0.040, Cramér's V = 0.104), especially women. Age-related differences in PROMs and PREMs were small. These findings suggest subtle but relevant patterns in patient-reported quality of asthma care and support age-sensitive, patient-centred approaches in primary care.
