The Lurie Children’s Child Injury Plausibility Assessment Support Tool (LCAST) is an app based on a validated Bruising Clinical Decision Rule (BCDR) called the TEN-4-FACESp. Use of this tool has the potential to improve recognition of abuse in young children with bruising. This app functions only as a screening tool and cannot be used to diagnose abuse. The app applies to children less than 4.0 years of age with bruising. If the child is older than 4.0 and/or bruising is not present, this tool cannot be used. In those circumstances, alternative methods of screening for abuse are needed. WHY FOCUS ON BRUISING? Bruising is the most common injury resulting from physical abuse and is the most overlooked or misdiagnosed antecedent injury prior to an abuse-related fatality or near-fatality in a young child. Bruising occurs from both accidental and abusive trauma, but differences identified by the TEN-4-FACESp bruising clinical decision rule may allow improved and earlier recognition of the abused child. ABOUT THE APP: The app is intended for clinical use by licensed healthcare professionals and providers. The app can inform decision-making and be used as an educational tool for learning about bruising characteristics that commonly result from abusive and accidental injury. The core feature of the app is an interactive 3D body model that allows the user to utilize visual cues of the human body to input clinical observations. The result is the opportunity to compare a child’s bruise findings to the published evidence resulting from a NIH-funded multi-center study. The data that drive the app are based on 2,161 patients of which 410 (19%) were classified by a multi-disciplinary panel of medical experts as abuse and 1,713 (79%) as accident. The TEN-4-FACESp bruising clinical decision rule resulted from analysis of 35 body regions and is 96% specific and 87% sensitive for distinguishing bruising from abuse versus accident. The TEN-4-FACESp has three components based on: 1) specific body regions with bruising, 2) patterned bruising, and 3) bruising anywhere on non-mobile infants. An affirmative finding for any one of the three TEN-4-FACESp components without a clear and reasonable explanation indicates a potential risk for abuse. The child may warrant further evaluation and consultation with an expert in child abuse should be considered. In addition to using the data in this app, the user should always check with a doctor before making any medical decisions.

INDIVIDUAL OR INSTITUTIONAL SUBSCRIPTION REQUIRED. The AIS Digital Dictionary is a powerful, specialized tool designed for medical professionals, trauma specialists, and emergency responders to accurately assess and code injuries sustained in automotive accidents. Developed by the Association for the Advancement of Automotive Medicine (AAAM), this app provides seamless access to the Abbreviated Injury Scale (AIS)—the internationally recognized standard for injury severity classification. This app is designed for use by medical professionals who already have an active license from AAAM. Key Features - AIS Code Search & Selection Effortlessly search for AIS codes by entering medical terms such as head, neck, foot, or by browsing injury descriptions. Quickly locate and assign the most precise injury classification for each patient case. - Case Management System Create and manage patient cases with ease. Add key details such as patient name, age, gender, and injury location, then systematically document injuries using AIS codes to ensure comprehensive assessment. - Automated Severity Scoring Each case dynamically calculates and displays critical injury severity metrics: ISS (Injury Severity Score) NISS (New Injury Severity Score) MAIS (Maximum Abbreviated Injury Scale) These scores provide a clear representation of the patient's condition, assisting in triage and medical decision-making. - 3D Injury Visualization Gain deeper insights into patient injuries with an interactive 3D anatomical model. The 3D View highlights affected areas on a digital skeleton based on the injuries added to a case, offering a visual representation of trauma impact. - Localization for Precise Injury Documentation Enhance case accuracy with injury localization. Specify the exact site of an injury—such as left foot or right second toe—to ensure clarity and consistency in reporting. - Reference & Documentation Access Stay informed with integrated access to medical guidelines, FAQs, and key reference documents, ensuring that practitioners have the latest resources at their fingertips.
