This is a protocol for a Cochrane Review (Intervention). The objectives are as follows:

1. To assess the effects of the use of collaborative writing applications on process outcomes (including the behaviour of healthcare professionals) and patient outcomes

2. To critically appraise and summarise current evidence on the resource use, costs, and cost‐effectiveness associated with collaborative writing applications to improve professional practices and patient outcomes

3. To explore the effects of different collaborative writing application features (e.g., open versus closed) and different implementation factors (e.g., the presence of a moderator) on process outcomes and patient outcomes
