In healthcare, interest in both evidence-based medicine (EBM) and patient-centered care (PCC) has grown over the past decade. While one could anticipate that a combination of EBM and PCC would enhance patient care, these two concepts also represent conflicting tendencies: standardization based on scientific knowledge and customization of medical practice based on patient and family preferences. To properly utilize EBM to deliver effective patient care, the Institute of Medicine has provided an updated definition of EBM that incorporates elements of PCC in clinical decision making; EBM provides specific tools for delivering high-quality care, and patients are involved in decision-making about the application of those tools [1,2]. Ideal healthcare decision making therefore requires that patients receive proper education using evidence-based data. To meet this end, patient decision aids have been utilized in various fields of medicine, including cardiology, urology, gynecology, endocrinology, oncology, and anesthesiology [3].The current issue of the Korean Journal of Anesthesiology (KJA) includes a randomized controlled trial conducted by Wang et al. [4] that evaluates whether providing patient decision aids on two neuromuscular blocking agent reversal options (neostigmine and sugammadex) to patients undergoing surgery under general anesthesia increases patient satisfaction with the decision-making process. A total of 3,132 surgical patients were recruited for this study from two medical centers, 2,986 of which completed the survey and were allocated to either the classical group, which received a standard explanation, or the PtDA group, which received a set of patient decision aids developed and tested by anesthesiologists from the two hospitals. The patients' degree of satisfaction with the decision-making process was evaluated using blinded outcome assessors, which included the four SURE (sure of myself, understand information, risk-benefit ratio, encouragement) screening test items. The patients' baseline information and medical knowledge were also assessed. Compared to the classical group, the PtDA group felt more confident they had received sufficient medical information (P < 0.001), felt better informed about the advantages and disadvantages of the medications (P < 0.001), exhibited a superior understanding of the benefits and risks of their options (P < 0.001), and felt more confident about their choice (P < 0.001). These observations suggest that patient decision aids can be used to improve the quality of communication between physicians and patients and promote shared decision making.As anesthesiologists generally perform the pre-anesthesia evaluation and consultation immediately before surgery, time is often limited and no established relationship with the patients and their families exists. Consequently, it may be difficult to provide anesthesia-related information adequately for patients to participate in the decision-making process without experiencing undue anxiety. Patient decision aids may thus be ...
