Perceptions towards Orthopaedic Injuries, In this pilot project, we are investigating patients` perceptions towards isolated orthopaedic injuries and look for differences between the Hispanic and Caucasian patient population. Outcome measures include the Consumer Assessment of Healthcare Providers and Systems (CAHPS) Cultural Competence (CC) item set, the Pain Catastrophizing Scale (PCS), the Injustice Experience Questionnaire (IEQ), and the optimism domain of the Somatic Pre-Occupation and Coping (SPOC) questionnaire. The study is a collaboration between the orthopaedic department and the School of Public Health and I am mentoring a Master of Public Health student on this project. The results of this study will be used for the planning of a larger subsequent clinical investigation with the goal to apply for federal funding sources.
