Application of a prescribing indicators tool to assist in identifying drug-related problems in a cohort of older Australians

Objective

Drug-related problems (DRPs) are common in older people, resulting in a disproportionate number of serious medication adverse events. Pharmacist-led interventions have been shown to be effective in identifying and reducing DRPs such as medication interactions, omission of recommended medications and use of ineffective medications. In 2008 we proposed a prescribing indicators tool to assist in identifying DRPs as part of the Australian medication review process. The objective was to apply the proposed prescribing indicators tool to a cohort of older Australians, to assess its use in detecting potential DRPs.

Methods

The prescribing indicators tool was applied in a cross-sectional observational study to 126 older (aged ≥65 years) English-speaking Australians taking five or more medications, as they were being discharged from a small private hospital into the community. Indicators were unmet when prescribing did not adhere to indicator tool guidelines.

Key findings

We found a high incidence of under-treatment, and use of inappropriate medications. There were on average 18 applicable indicators per patient, with each patient having on average seven unmet indicators.

Conclusion

The use of a prescribing indicators tool for commonly used medications and common medical conditions in older Australians may contribute to the efficient identification of DRPs.
