Medical Device Alerts (MDAs) were introduced on 1 January 2003, to replace the previous types of safety warnings (Hazard notice, Safety notice, Device alert, Advice notice and Pacemaker technical note) which can be found under Publications > Safety warnings.
MDAs are distributed to the NHS in England via the Department of Health's Central Alerting System (CAS). MDAs remain valid unless they are updated or withdrawn. They are reviewed once they are five years old (and subsequently every year) and the lists on this website are amended accordingly.
