The reporting requirements of case reports and adherence of case report reporting guidelines in medical journals: an analysis of the authors' guide sections.

backgroundOwing to the growth of case reports and changes in the policy of journals in publishing this evidence, the need to standardize them is felt more than before. Therefore, in this study, the authors' guide of medical journals indexed in the Scopus database that published most of the case reports has been analyzed to identify the reporting requirements and emerging case report types.

methodsA total of 50 journals were selected from the Scopus citation database (the world's largest knowledge base) that published most of the case reports. These and the authors' guideline section on the types and requirements of writing case reports were analyzed by inductive content analysis.

resultsMost of the case reports were published in the fields of dermatology and surgery and general medicine. Reporting requirements in author's guide are grouped in four categories: (1) reasons for publication or content value, (2) emphasis on the patient consent form and confidentiality, (3) emphasizing the constraints on the word count and limitation, and (4) recommendation for structure and reporting elements. In terms of adherence to the reporting guidelines, 76% of journals do not adhere to any reporting guideline. In addition, 13 types of case reports were identified in these journals, among which traditional case reports, clinical image, letters, and case series were the most widely used formats.

conclusionsImproving the publication processes of case reports has been left unattended by international organizations. The policies of journals need to become more integrated, and reporting guidelines should be modified or redeveloped to enhance the quality of publications, cover different reporting requirements, and consequently, benefit from the evidence value available in case reports.
