The next four decades will see a marked expansion of the elderly population in Ireland, in particular people aged over 80 yrs. Persons aged over 80 are the highest consumers of prescription medicines in Ireland and have the highest prevalence rates of major polypharmacy. Polypharmacy is intimately linked with serious adverse drug events (ADEs) and consequent major morbidity and mortality. Epidemiological data from the United States indicate that ADEs is the fifth most common cause of death nationally. Experts suggest that effective evidence based interventions can be applied to this major public health problem.
Recent research data indicate a cause-and-effect relationship between inappropriate prescription medicines and serious ADEs in older people in hospital. To date, Beers' criteria have been the dominant set of criteria for defining potentially inappropriate medicines (PIMs) in late life. Research data collected by this group show that the recently validated STOPP/START criteria (Screening Tool of Older Persons' Prescriptions and Screening Tool to Alert doctors to Right Treatment) identify ADEs that are causal or contributory to acute hospital admission in older people 2.7 times more frequently than Beers' criteria. Based on these findings, our hypothesis is that STOPP/START criteria have the potential to be used as a regular intervention for the purpose of ADE prevention in older people. A recent single centre randomised control trial (RCT) undertaken at Cork University Hospital showed that prospective application of STOPP/START criteria led to a highly significant improvement in medication appropriateness in older hospitalised patients compared with standard inpatient pharmaceutical care. Significantly, the improvement in medication appropriateness was maintained to the end of the study follow-up i.e. 6 months post-discharge. However, the ability of STOPP/START criteria to significantly reduce ADEs in a prospective RCT has yet to be demonstrated.

|Active Comparator: Application of STOPP/START criteria||
Other: Application of STOPP/START criteria
The researcher will apply the STOPP/START criteria to the cases randomised to this intervention. This will occur at the point of recruitment into the study and consists of applying STOPP/START criteria to the list of prescribed medications the patient is taking at that time point.
Where potentially inappropriate medications (PIM's) are identified using the intervention, these are highlighted to the medical team with primary responsibility for the patient both verbally and in writing. The relevant registrar will be contacted in person or via telephone by the researcher and informed of the PIM's in addition to a standard medication advice form inserted into the patients' notes also highlighting the PIM's.
Other Name: STOPP/START criteria for potentially inappropriate medications in older people.
