Objective:
This study evaluated the impact of a specialized dementia nursing program on cognitive function, self-care ability, psychological status, and quality of life in patients with Alzheimer's disease (AD).
Methods:
Data from 131 AD patients admitted to our hospital between January 2019 and August 2021 were analyzed. Based on the nursing method, the patients were divided into a control group that received routine nursing care (n = 58) and an intervention group that implemented routine nursing care combined with specialized nursing (n = 73). Psychological status, daily living and self-care ability, cognitive function, quality of life, and nursing satisfaction were compared between the two groups.
Results:
After specialized nursing, the intervention group showed significantly greater reductions in HAMA and HAMD scores and greater increases in CD - RISC, ADL, and ESCA scores compared with the control group (p < 0.05). The intervention group also had higher MMSE, ADCS - ADL, and DQOL scores and lower ADAS - Cog scores compared to the control group (p < 0.05). Nursing satisfaction was also higher in the intervention group than in the control group (p < 0.05).
Conclusion:
Specialized dementia nursing can enhance cognitive function, self-care ability, psychological resilience, and quality of life in AD patients, and increases satisfaction with nursing care.
