PURPOSE: This study was done to analyze the effects of tele-care case management services using secondary data. METHODS: A descriptive research design was utilized, and the participants were 134 medical aid beneficiaries who were in either the high-risk group or the preventive group. Case management services were delivered by 8 care managers. Data were analyzed using PAWS Statistics 17 through descriptive statistics and paired t-test. RESULTS: After the case management intervention, the participants' health quality of life, self-care competency, and reasonable medical care utilization increased significantly for the high-risk group. However there were no significant changes in the preventive group. CONCLUSION: The results showed that the tele-care case management services were effective for high-risk medical aid beneficiaries. Further studies with controls for constitutional variables and a comparison group are required to validate the robustness of the effectiveness of the case management program in the present study.
