OBJECTIVES: This study aimed to summarize and analyze the utilization of oriental medical services in korea. METHODS: We searched studies on the utilization of oriental medical services over the past 10 years (2001-2011) from 3 Korean databases (National Assembly Library, Research Information Service System, and National Discovery for Science Leaders). The reviewers also conducted a summarizing analysis by sampling the literature according to the type of study, study period, region, study subjects, sample size, type of sampling, research method, data analysis, study instruments, main results, etc. RESULTS: We were obtained 17 studies that involved the utilization of oriental medical services. We found that women, elderly patients, and patients with low education levels and those with musculoskeletal and cerebrovascular diseases preferred to use oriental medical services. Other variables such as trust and kindness of staff and positive perceptions of the treatment effect were found to be important determinants for utilizing oriental medical services. CONCLUSIONS: The utilization of oriental medical services would be related with gender, age, education levels and diseases. Also to confirm the reasons for patients to choose oriental medical services, further studies should be conducted using the highest methodological standards.
