Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Using Focus Groups as a Tool to Research Learning: A Demonstration and a Discussion

This interactive session includes a focus group dealing with the theory and measurement of learning from simulations and experiential exercises. A discussion of the "how to’s” of this technique is provided along with evaluation of its potential as a assessment tool in this area

Using the Integrative International Simulation INTOPIA Mark 2000 in a Concentrated MBA Curriculum

This paper chronicles the development, conduct, and initial evaluation of a course, which used the play of the formidable integrative international simulation INTOPIA Mark 2000 as its primary learning tool. This case study provides concrete examples what worked, what did not, and the inevitable “surprises” which arise when using business simulations and experiential learning
