OBJECTIVE: To develop consensus guidelines for management of delirium and to assess their effectiveness in improving the outcomes and process of care in delirium. METHOD: Guidelines for delirium were developed following a literature search and a formal multi-disciplinary consensus process using a two-stage Delphi technique. The process and outcomes of patients with delirium were then observed in a ‘before’ (211 patients) and an ‘after’ study (125 patients). Three levels of intervention were made in the ‘after’ study.
