National clinical sentinel audit of evidence-based prescribing for older people

To audit the performance of hospitals in evidence-based prescribing.

All hospitals in England were invited to participate. The audit was completed in 62 hospitals.

Prescribing and clinical data were collected on 100 consecutive medical inpatients aged >/= 65 years at each site, enabling evaluation of eight prescribing indicators before and after intervention. The data were collected using a specifically designed database.

The results of the first audit were available immediately from the software and a national report with locally identifiable information was returned to hospitals. Hospitals were encouraged to design and deliver their own intervention strategy. A questionnaire was sent to all hospitals to document prioritization of indicators.

Generic names were used for 36 061 (82.6%) in 1999 and 39 188 (86.4)% in 2000. In 1999, 50% (3074) of patients had documentation of allergy status. This increased to 60% (3684) in 2000. For 21.2% of patients prescribed paracetamol in 1999 and 18.1% in 2000, the prescription was written such that it was possible to exceed the maximum recommended dose of 4 g in 24 hours. Long-acting hypoglycaemic drugs were prescribed to 29 patients in 1999 and 20 patients in 2000. Anti-thrombotics were used appropriately for 54% (520/966) of patients in atrial fibrillation in the first audit and 57% (579/1019) in the second audit. The appropriate use of aspirin increased from 91% (595/651) to 94% (725/772) and the appropriate use of benzodiazepines dropped from 49% (537/1088) to 47% (460/966) between the audits. For three indicators, the allocating of a high priority translated into a bigger improvement between the audits.

Local ownership of data and the quality improvement process, and provision of national benchmarking data did not result in a significant improvement in prescribing in the second audit.
