Guidance Documents for Off-Label Drug Use Management for Chinese Health Care Institutions: A Scoping Review.

Abstract

Background: Off-label drug use (OLDU) is a common practice in health care institutions, and numerous guidance documents have been developed to guide the management of OLDU in China. This scoping review aims to compare these documents and identify existing issues.

Methods: PubMed, EMbase, three Chinese databases, the National Public Service Platform for Standards Information and the official websites of pharmaceutical-related associations were searched to identify guidance documents relevant to the management of OLDU for Chinese health care institutions. We extracted and compared the recommended practices for various aspects of OLDU management, including management systems, organizational structure, prerequisites for OLDU, approval processes, evidence-based evaluation, informed consent, and other related aspects.

Results: A total of 16 guidance documents were included, comprising 12 expert consensuses, 2 practice guidelines, and 2 group standards. Only six documents provide specific requirements for the establishment of management systems. Management of OLDU requires involvement from multiple departments or committees, yet only a few documents explicitly delineate the supervisory authority, and the responsibilities of the parties involved. These documents also show significant disparities in their approval process, evidence-based evaluation, and informed consent recommendations. Furthermore, only a minority of the documents provide specific requirements for training and assessments focused on OLDU and improving adverse reaction monitoring.

Conclusion: These guidance documents differ significantly in their specific recommendations for the management of OLDU and lack sufficient emphasis on certain critical aspects. It may be beneficial for health administrative authorities to promote the development of unified national guidelines.
