Objectives: To explore the effect of care transitions intervention (CTI) on the sense of benefit-finding of caregivers for patients with acute cerebral infarction (ACI). Ninety caregivers for patients with ACI were divided into two groups according to the random number table method (n = 45 in each group). Methods: The control group was given regular health guidance, and the intervention group was given care transitions intervention on the basis of the guidance used in the control group. The changes in the sense of benefit-finding and quality of life between the two groups were compared before and after the intervention. Results: There was no statistically significant difference in caregivers between the two groups in gender, age, educational level, occupational status, gender and age of the patients, activities of daily living (ADL) scores before discharge, and the relationships between the caregiver and the patient. Before CTI, there was no statistically significant difference in the caregivers' sense of benefit-finding (including sense of benefit, family relationship, personal growth, social relationship and healthy behavior) and quality of life (including benefit-finding of care, stress of care, choice of care, support to care and money issue) between the two groups. While after CTI, the scores of each dimension of the caregivers' sense of benefit finding and quality of life in the intervention group were significantly higher than those in the control group (p < 0.05). Conclusions: The CTI can help improve the sense of benefit-finding and quality of life of caregivers for patients with ACI.
