Abstract

Medical auditing has moved beyond the traditional chart review to the process audit, which identifies deficiencies in care and suggests remedies. In 1981 the audit committee of the Department of Psychiatry at Toronto General Hospital audited the use of hypnotic drugs in the inpatient unit. The audit produced two recommendations: that nursing staff record sleep graphs for inpatients more often, and that an educational program be instituted to change the physicians' patterns of prescribing hypnotics. In 1983 the audit was repeated to test the effectiveness of the 1981 auditing process. The 1981 recommendation produced the desired improvement in recording of sleep graphs. However, the medical staff failed to change their patterns of prescribing hypnotics: oxazepam remained the preferred hypnotic. For the process audit to be effective in improving patient care those using it must ensure that the methods reflect the nature and structure of the professional group they are trying to influence.
