Advanced practice nurses in the pre-surgical care center of a children's hospital that performs over 10,000 surgeries per year, were confronted with multiple obstacles when trying to obtain accurate and complete medication histories of children with chronic conditions scheduled for surgery. The need to obtain this medication information was critical to the process of medication reconciliation and is especially important for children with chronic conditions as there is a greater likelihood that they will be on multiple medications.  Without medication information, the potential for patient harm increases as the risk of adverse medication events such as incorrect medication regime, adverse drug events, and potential interactions rises. The potential for patient harm was high because historically, few parents were bringing their child's medications to the pre-surgical evaluation as requested.  An interdisciplinary team was formed to develop and implement evidence-based practice changes. A review of the literature revealed limited research on obtaining an accurate and complete medication history from parents. Because descriptive studies should be considered when systematic reviews of randomized clinic trials are not available, and parental choices and concerns must be taken into account when implementing evidence-based practice, a descriptive study was conducted to identify what factors parents identified as influencing their decision whether to bring their child's medications to the pre-operative evaluation. This presentation focuses on the results of this study and the efforts of an interdisciplinary team to foster medical reconciliation for children with chronic conditions scheduled for surgery.
