Evaluating And Reducing The Effects Of Misclassification In A Sequential Multiple Assignment Randomized Trial (Smart), Jun He
Theses and Dissertations
SMART designs tailor individual treatment by re-randomizing patients to subsequent therapies based on their response to initial treatment. However, the classification of patients being responders/non-responders could be inaccurate and thus lead to inappropriate treatment assignment. In a two-step SMART design, by assuming equal randomization, and equal variances of misclassified patients and correctly classified patients, we evaluated misclassification effects on mean, variance, and type I error/ power of single sequential treatment outcome (SST), dynamic treatment outcome (DTRs), and overall outcome. The results showed that misclassification could introduce bias to estimates of treatment effect in all types of outcome. Though the magnitude …
Utilization Of Simulation To Teach Pelvic Examination Skills To Medical Students: Implications For Medical Education, Brenda Seago
Utilization Of Simulation To Teach Pelvic Examination Skills To Medical Students: Implications For Medical Education, Brenda Seago
Theses and Dissertations
Medical education is changing. Physicians have less time for teaching clinical skills and for direct observation of medical students, due to sicker patients in the hospital, shorter hospital stays, competing demands of research and patient care, and implementation of the eighty hour work week for residents. The consumer movement increased awareness of medical errors, patient safety and quality of healthcare. Teaching the pelvic examination is ethically complex. Questions have arisen about medical students learning to conduct the pelvic examination on actual patients. This study utilizes the pelvic examination simulator and genital teaching associates (GTAs) to teach pelvic exam skills to …
