Custom and practice: A multi-center study of medicines reconciliation following admission in four acute hospitals in the UK

摘要

Background: Many studies have highlighted the problems associated with different aspects of medicines reconciliation (MR). These have been followed by numerous recommendations of good practice shown in published studies to decrease error; however, there is little to suggest that practice has significantly changed. The study reported here was conducted to review local medicines reconciliation practice and compare it to data within previously published evidence. Objectives: To determine current medicines reconciliation practice in four acute hospitals (A-D) in one region of the United Kingdom and compare it to published best practices. Method: Quantitative data on key indicators were collected prospectively from medical wards in the four hospitals using a proforma compiled from existing literature and previous, validated audits. Data were collected on: i) time between admission and MR being undertaken; ii) time to conduct MR; iii) number and type of sources used to ascertain current medication; and iv) number, type and potential severity of unintended discrepancies. The potential severity of the discrepancies was retrospectively dually rated in 10% of the sample using a professional panel. Results: Of the 250 charts reviewed (54 Hospital A, 61 Hospital B, 69 Hospital C, 66 Hospital D), 37.6% (92/245) of patients experienced at least one discrepancy on their drug chart, with the majority of these being omissions (237/413, 57.1%). A total of 413 discrepancies were discovered, an overall mean of 1.69 (413/245) discrepancies per patient. The number of sources used to reconcile medicines varied with 36.8% (91/247) only using one source of information and the patient being used as a source in less than half of all medicines reconciliations (45.7%, 113/247). In three out of the four hospitals the discrepancies were most frequently categorized as potentially requiring increased monitoring or intervention. Conclusion: This study shows higher rates of unintended discrepancies per patient than those in previous studies, with omission being the most frequently occurring type of discrepancy. None of the four centers adhered to current UK guidance on medicines reconciliation. All four centers demonstrated a strong reliance on General Practitioner (GP)-based sources. A minority of discrepancies had the potential to cause injury to patients and to increase utilization of health care resources. There is a need to review current practice and procedures at transitions in care to improve the accuracy of medication history-taking at admission by doctors and to encourage pharmacy staff to use an increased number of sources to validate the medication history. Although early research indicates that safety can be improved through patient involvement, this study found that patients were not involved in the majority of reconciliation encounters.
