Abstract (up to 200 words):
An educational application has been developed at the Brody School of Medicine at East Carolina University to improve students and health professionals identification of pediatric heart sounds and murmurs. The application, initially developed as a CD-ROM for classroom presentation, self-paced learning, and continuing education, has been ported to the Web. It incorporates a user-friendly interface with high fidelity digitally recorded heart sounds, supporting didactic text, illustrations, and a self-assessment. The learner can listen to heart sounds that correspond to the four chest locations commonly auscultated, more closely simulating an actual examination. The application was evaluated by 32 neonatal and pediatric nurse practitioner students at the UNC School of Nursing. Students accessed the application over a high bandwidth link of 155 kilometers (96 miles) between UNC and the Web server at ECU. Using pre- and post-testing, there was significant improvement following four weeks of use. Students with relatively less years of experience improved more than those with relatively more years. The more time students invested in using the tutorial, the greater their improvement in accurately identifying heart sounds. Development was funded by the Children's Miracle Network and the National Library of Medicine. The CD-ROM is marketed by Concept Media of Irvine, California.
