Abstract text
Background: One of the elective functions of a Cochrane Field is to establish and maintain a register of trials specific to the field’s specialty and to submit this register to the Cochrane Central Register of Controlled Trials. To ensure the register is comprehensive, non-English language sources can be searched and where necessary translations of records are undertaken and incorporated into the register. Objectives: To develop and launch a multilingual clinical trials register for the nursing care community to inform nursing practice and to identify gaps in nursing knowledge. Methods: Funding was received to establish a trials register for the Cochrane Nursing Care Field (CNCF). Initial planning of the register included defining the scope and topics to be covered by the register, developing a search strategy, establishing the keywords and headings to be used in the search, determining the databases to be searched, deciding on the time period for studies to be included in the register, documenting the types of studies to be included in the register, determining the details to be included for each study entered into the register and entering the studies into the Cochrane Register of Studies. Results: The CNCF Trials Register was launched in 2013. While preliminary planning focused on standardization of processes, the next phase revolved around developing methods for incorporating data from non-English language sources. Collaboration with our Chinese colleagues to integrate simplified Chinese records resulted in a number of challenges. Issues regarding current variation in practice, criteria development, quality control, updating and communication arose. Conclusions: The CNCF has developed and launched a trials register that includes records from non-English language sources. Consequently a number of challenges have arisen as a result and may serve as a guide for other entities.
