The Trust at which I work had a serious issue with misuse of DATIX, with the CQC highlighting the issue of staff-disengagement that resulted. I approached the then-FTSU Guardian with information on a web-app, Cloud-based pseudo-anonymised engagement platform that staff could use to raise issues without fear of retribution. That platform has now been in-service for around six months, supporting the Guardian, and providing a channel of communications beyond FTSU, and includes access to many departments and Trust execs.
DATIX has a place in patient safety, but there may be better alternatives. Surgical specialist teams for example, have the CORESS confidential reporting system (https://www.coress.org.uk/), while some might find platforms such as 'Say-So' (https://www.say-so.co.uk/) or WorkInConfidence (https://www.workinconfidence.com/) more appropriate.
