WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT • Managing a patient's medication(s) at points around transfer of care is central to patient safety and high quality care. • Medication use at these points carries the potential for miscommunication and medication error. • Processes of reconciliation can help to reduce the prevalence of miscommunication and error, improve continuity of appropriate medication use and improve communication across different settings. However, such processes are resource intensive. WHAT THIS PAPER ADDS • Medication details documented at discharge from acute hospital care in Ireland frequently contain prescription writing errors or fail to communicate information regarding changes made during inpatient care (collectively referred to as non‐reconciliations). This carries the potential to cause harm or unplanned re‐admission. • The medication classes that are more likely to be omitted at admission or discharge were identified, as were those involved in failure to document changes made during inpatient care, for example stopping or withholding. • Patients experiencing chronic illness and using an increasing number of medications were identified as being at greatest risk of experiencing non‐reconciliation, and it is recommended that processes of reconciliation should be prioritized for these patients. • Processes that require the same medication details to be written more than once increase the likelihood of non‐reconciliation. AIMS Movement into or out of hospital is a vulnerable period for medication safety. Reconciling the medication a patient is using before admission with the medication prescribed on discharge, and documenting any changes (medication reconciliation) is recommended to improve safety. The aims of the study were to investigate the factors contributing to medication reconciliation on discharge, and identify the prevalence of non‐reconciliation. METHODS The study was a cross‐sectional, observational survey using consecutive discharges from purposively selected services in two acute public hospitals in Ireland. Medication reconciliation, potential for harm and unplanned re‐admission were investigated. RESULTS Medication non‐reconciliation was identified in 50% of 1245 inpatient episodes, involving 16% of 9569 medications. The majority of non‐reconciled episodes had potential to result in moderate (63%) or severe (2%) harm. Handwritten rather than computerized discharges (adjusted odds ratio (adjusted OR) 1.60, 95% CI 1.11, 2.99), increasing number of medications (adjusted OR 1.26, 95% CI 1.21, 1.31) or chronic illness (adjusted OR 2.08, 95% CI 1.33, 3.24) were associated with non‐reconciliation. Omission of endocrine, central nervous system and nutrition and blood drugs was more likely on discharge, whilst omission on admission and throughout inpatient care, without documentation, was more likely for obstetric, gynaecology and urinary tract (OGU) or respiratory drugs. Documentation in the discharge communication that medication was intentionally stopped during inpatient care was less likely for cardiovascular, musculoskeletal and OGU drugs. Errors involving the dose were most likely for respiratory drugs. CONCLUSIONS The findings inform strategies to facilitate medication reconciliation on discharge from acute hospital care.
