In our commitment to creating a world of well-being for all children, Children’s Mercy Kansas City has created PedsGuide as a means for evidence-based pediatric clinical support guidelines to be available to health care providers. PedsGuide is a multi-module pediatric clinical support tool intended for use only by professional health care providers and emergency personnel for informational and educational purposes. *Each module provides users with a step-by-step interactive clinical decision support process, including reference material and/or contextually relevant information based on evidence-based practice and expert opinion routinely used in clinical practice, to assist in management of various acute illnesses in children. The modules have been designed and optimized by an interdisciplinary team of clinicians, pharmacists, medical librarians, Human Factors scientists, and innovations professionals. Human Factors methodology was leveraged to guide interfaces that provide rapid access to information and assessment tools, which facilitate an efficient aid for care management while decreasing cognitive load for the user. Additionally, for users who seek care for patients at The Children’s Mercy Hospital, PedsGuide features a quick-call feature to contact the Children’s Mercy Contact Center and Critical Care Transport Team in our service area. *While PedsGuide is a helpful tool, it is not intended to replace the independent judgment and evaluation of health care providers and emergency personnel. Healthcare providers and emergency personnel should not rely primarily on the tool to make a clinical diagnosis or treatment decision. Children's Mercy is not responsible for the correctness of any action you take based upon your use of PedsGuide.
