First in a three-part series, using a systems approach to study the disease entities commonly encountered in ambulatory and hospitalized patients. Focus is on understanding illness, particularly the criteria for making a diagnosis (including an understanding of signs and symptoms), and developing and implementing the appropriate patient management plan. Analyses include evaluating normal and abnormal laboratory, diagnostic, and radiographic findings, when appropriate. Additional topics include issues related to the appropriate referral of patients. Principles and guidelines for organizing and developing a structured approach to thinking about patient care are addressed during lecture, with practical application in a simulated patient scenario format. The scenarios are complete and require thorough decision making at all levels, from patient presentation to treatment or referral, as appropriate. Exercises that involve review and interpretation of current medical literature promote development of lifelong learning skills. 5 Credits (3 Lecture - 6 Lab) Corequisite(s): PHA316 and PHA322 and PHA375.
