International audience. Background Nursing home‐acquired pneumonia (NHAP) and related hospitalizations might lead to abrupt functional declines, especially among nursing home residents. Intrinsic capacity is a novel construct proposed by the World Health Organization specifically designed to capture the physical and cognitive capacities of the aging individual to design personalized interventions. This study aimed to investigate the associations of NHAP and related hospitalizations with several intrinsic capacity domains among nursing home residents. Methods We used data from the INCUR study ( n = 754; mean age = 86.1 ± 7.4; 75.2% female). Four intrinsic capacity domains were assessed through the Short Physical Performance Battery (SPPB, locomotion), Abbreviated Mental Test (cognition), 10‐items Geriatric Depression scale (GDS‐10, mood), the Mini‐Nutritional Assessment Short‐Form (vitality) at three time‐points along 1‐year. Linear mixed models were used to analyze longitudinal evolution in the intrinsic capacity domains according to NHAP diagnosis and hospitalization. Results A total of 161 (21.4%) were diagnosed with NHAP, and 46 of them (28.6%) required hospitalization. NHAP was significantly associated with declines in the intrinsic capacity vitality domain (β = −0.51; 95% CI −0.84; −0.18). The association was also found for NHAP‐related hospitalization (β = −0.97; 95% CI −1.46; −0.48). NHAP‐related hospitalization was also associated with worsening in the psychological domain (β = 0.56; 95% CI 0.08; 1.04). No other significant associations were found. Conclusions NHAP and related hospitalization are associated with the deterioration of intrinsic capacity vitality and psychology domains. Prevention of pneumonia may result in better functional evolution in very old and vulnerable nursing home residents.
