Longitudinal profiling of adverse events in Irish hospitals and provision of a standardised assessment tool to the Irish healthcare system: the INAES-2 study

Adverse events (AEs) are unintended injuries or complications that are caused by healthcare management, rather than a patient's underlying disease, which lead to death, disability at the time of hospital discharge, prolonged hospital stay or subsequent hospitalisation. The first Irish National Adverse Events Study (INAES) determined the prevalence and nature of AEs in Irish hospitals using in-patient admissions from 2009. The INAES reviewed the medical charts of 1574 patient admissions to 8 acute Irish hospitals using an internationally standardised 2-stage methodology. AEs were classified according to their nature, preventability, severity and impact on the patient. The study showed that one-in-eight patients (12.2%) experienced an AE as a result of hospital care in 2009, broadly in line with international figures where AE rates ranged from 3-17% of hospital admissions. Over 70% of events were considered preventable and added an average of 6.1 days in hospital, representing an expenditure of
