PIP is associated with increased morbidity, adverse drug events, hospitalisation and mortality and high levels have been reported among older people in NI and ROI Fifty two prescribing indicators Autophagy signaling pathway inhibitor from the Screening Tool of Older Persons potentially inappropriate Prescriptions (STOPP) criteria were applied to data on prescriptions and clinical diagnoses, extracted from the UK Clinical Practice Research Datalink (CPRD), in order to determine

the prevalence of PIP The prevalence of PIP among older people in the UK was high and increased with polypharmacy. The most common inappropriate medications were consistently the same in the UK, NI and ROI. Potentially inappropriate prescribing (PIP) in older people is associated with increases in morbidity, adverse drug events, hospitalisation and mortality.1,2 We sought to estimate the prevalence of PIP, in the United Kingdom (UK) population aged ≥70 years, to investigate factors associated learn more with PIP and to compare UK PIP prevalence with that reported in neighbouring

regions. A retrospective cross-sectional population study was carried out among those aged ≥ 70 years, in the UK Clinical Practice Research Datalink (CPRD), in 2007. Data on prescriptions and clinical diagnoses were extracted from the CPRD. Fifty two PIP indicators from the Screening Tool of Older Persons potentially inappropriate Prescriptions (STOPP) criteria, used to assess medication appropriateness, were applied to these data. PIP prevalence according to individual STOPP criteria and the overall prevalence of PIP (based on the number of potentially inappropriate medications) were estimated. The relationship between PIP and polypharmacy (defined as ‘the use of four or more repeat medications’), comorbidity, age, and gender was examined using logistic regression. In order to facilitate comparison of PIP

prevalence in the UK to that reported Digestive enzyme in Northern Ireland (NI) and the Republic of Ireland (ROI), a subset of the STOPP criteria, comprising 28 indicators, were applied to the data. Ethical approval for all observational research using GPRD data has been obtained from a Multicentre Research Ethics Committee The overall prevalence of PIP in the study population (n = 1,019,491) was 29% (295,653 patients). Almost 15% of the population (148,614 patients) were prescribed one potentially inappropriate medication, 77,923 (7.64%) were prescribed two potentially inappropriate medications and 69,116 (6.78%) were prescribed three or more potentially inappropriate medications. The most common examples of PIP identified were therapeutic duplication (12,1668 patients; 11.93%), followed by use of aspirin with no history of coronary, cerebral or peripheral vascular symptoms or occlusive arterial event (115,576, patients; 11.
