The commission has published 'intelligent monitoring reports' to aid its inspectors in deciding which of the NHS trusts (who provide mental health services) to prioritise. The new model considers 59 separate levels of evidence including bed occupancy, the NHS staff survey, the national health outpatient survey, together with concerns raised by trust staff. The model is augmented by local information from partners and the public.
