• Medication reconciliation is defined by the American Society of Health- System Pharmacists (ASHP) and the American Pharmacists Association (AphA) as “the comprehensive evaluation of a patient’s medication regimen any time there is a change in therapy in an effort to avoid medication errors such as omissions, duplications, dosing errors or drug interactions, as well as to observe compliance and adherence patterns “. Medication reconciliation is very important to avoid medication errors but it is also a complex and time-consuming process. Medication histories, i.e. records of prescription, purchase, and refill sequences are considered to be a resource from which conclusions about medication reconciliation can be drawn. However, medication histories spread across diverse paper and electronic media may lack the required accuracy. By employing multiple electronic sources this thesis will evaluate if more accurate medication histories can be collected.
