Objective To explore the effectiveness of applying 3N linked care model among caregivers of leukemia patients.

Methods A total of 96 caregivers of acute leukemia patients were selected and randomly divided into observation groupand control group using a random lottery method, with 48 caregivers in each group. The observation group received the 3N linked care model, while the control group received routine care. Psychological resilience, caregiving burden, and nursing outcomes were compared between the two groups.

Results After intervention, the total score on the Connor Davidson Resilience Scale (CD-RISC) in the observation group was higher than that in the control group(105.23±6.24) versus (91.20±5.06), P < 0.05. After intervention, the proportion of caregivers with no burden in the observation group was significantly higher than that in the control group, while the proportions of mild, moderate, and severe burdens were significantly lower (P < 0.05). The total nursing outcome score in the observation group was higher than that in the control group(28.54±2.36) versus (21.05±1.42), P < 0.05.

Conclusion The application of 3N linked care model among caregivers of leukemia patients helps improve caregivers' levels of psychological resilience, reduce their caregiving burden, and enhance nursing outcomes.
