Older individuals generally suffer from multiple co-morbidities and this makes this

patient group particularly vulnerable to inappropriate prescribing (IP). IP has been

reported to be a substantial cause of morbidity and mortality and has been identified

as a major contributing factor to increased healthcare utilisation. One method of

evaluating or identifying inappropriate or sub-optimal prescribing practice is to use

validated evidence-based explicit criteria to define instances of potential IP. Two

sets of criteria have gained international recognition, i.e. Beers¿ criteria and

¿Screening Tool of Older Peoples Prescriptions (STOPP)¿.


The aim of this study was to determine the prevalence of potential IP in older nursing

home residents on the island of Ireland.


A total of 315 residents ≥65 years were randomly selected from fourteen nursing

homes from County Cork, Ireland and were age and gender matched with 315

residents from a Northern Irish nursing home dataset. Exclusion criteria included

terminally ill or respite patients. Both the Beers¿ and STOPP criteria were applied to

the patient profiles of the 630 residents in both Northern Ireland (NI) and the

Republic of Ireland (RoI).


Of the residents reviewed (n=630), 472 (74.9%) were female; the median age was

84 (IQR: 78-89) of the entire dataset. The total number of medicines prescribed for

the RoI dataset was 3,730 (median 11, IQR 9-13) and for the NI population was

3,394 (median 10, IQR 7-13). In the RoI dataset, 73.0% of residents had at least one

potentially inappropriate medication (PIM) identified by STOPP criteria and 54.3%

had at least one PIM identified by the Beers¿ criteria. In the NI dataset 67.0% of

residents had at least one PIM identified by STOPP criteria and 56.8% of residents

had at least one PIM identified by the Beers¿ criteria.


Potential IP is a major area of concern and has been implicated throughout the

literature as a substantial burden to health services internationally. In this study

STOPP criteria demonstrated superior capability over the Beers¿ criteria in the

identification of instances of potential inappropriate prescribing (PIP) in these nursing

home / long term care facility residents.
