This study investigates the effect of personalized care approaches on the well-being of elderly residents in nursing homes through a quantitative meta-analysis. Recognizing that traditional institutional care models often fail to address individual needs, this research synthesizes empirical and review-based evidence on person-centered, individualized, and tailored care interventions. Using a PRISMA-guided methodology, 30 relevant studies published between 2020 and 2026 were systematically reviewed, with 15 studies meeting inclusion criteria for quantitative synthesis. Effect sizes were extracted and standardized into correlation coefficients and analyzed using a random-effects model.

Results revealed a moderate-to-strong positive relationship (pooled r ≈ 0.52, p < .001) between personalized care approaches and elderly well-being outcomes, including psychological health, quality of life, emotional stability, and social engagement. Subgroup analyses indicated that psychosocial interventions, individualized activity programs, and person-centered nursing care produced the strongest effects. Findings also highlight the critical role of staff-resident relationships, autonomy support, and tailored care planning as mediating mechanisms.

The study concludes that personalized care is a core determinant of well-being in nursing homes and recommends integrating competency-based training, flexible care models, and individualized care systems into long-term care policies.
