Abstract
BACKGROUND: This study aims to review the current quantity and quality of case reports and case series published by clinical doctors who worked in local Korean medicine clinics. METHODS: Seven electronic databases, one in English and six in Korean, were searched for case studies authored by clinically-based Korean Medicine doctors (KMDs) and published in academic journals between January 2000 and December 2018. The following data were extracted: the number of cases per article, authorship order, types of academic journals, the number of articles published in the domestic or international academic journals by publication year, citation counts, and classification of diseases. We assessed the quality of the reports based on 28 items from the CAse REport (CARE) checklist. RESULTS: A total of 266 case reports or case series met the inclusion criteria. There were 125 articles (47.0%) in which all authors consist of who worked in Korean medicine clinics. The overall increase in the number of published articles by year showed a sharp increase after 2010. Articles were focused primarily on Korean medicine therapeutic and diagnostic approaches. The most commonly reported cases were diseases of the skin (346 or 40.9%). Overall, the quality of the reports was acceptable (75.3%) but several items such as diagnostic challenges, patient perspective, informed consent, intervention adherence and tolerability, and adverse events were substantially underreported. CONCLUSIONS: To improve disease diagnosis and treatment, KMDs in clinical practice should be encouraged to report and publish case studies, using the CARE checklist to ensure quality.
