Open access. The impact of flexible assertive community treatment (FACT) has been observed in people previously supported by assertive community treatment (ACT) teams, but its effect on those previously with a community mental health team (CMHT) has not been studied in the UK. An observational study was conducted of 380 people from 3 CMHTs and 95 people from an ACT team, all with a history of psychosis, following service reconfiguration to 3 FACT teams.
