Robustness Of Multiple Imputation Under Missing At Random (Mar) Mechanism: A Simulation Study, Priyanka Garg
Robustness Of Multiple Imputation Under Missing At Random (Mar) Mechanism: A Simulation Study, Priyanka Garg
Electronic Theses and Dissertations
Missing data is an unavoidable issue in controlled clinical trials and public health research and practice. Presence of missing data and applying inappropriate methods of analysis generates biased estimates and reduces power of study. It is very important for investigators to use appropriate methods of analysis to deal with missing data in order to maintain internal (power of study) and external (generalization of sample results to larger population) validity of study. The focus of this dissertation is to compare different methods to deal with missing data in controlled clinical trials and public health research and practice. In addition, this dissertation …

Evaluating The Efficacy Of A Childhood Lead Poisoning Risk Model As An Accurate Predictor Of Lead Exposure, Christopher R. Rustin
Evaluating The Efficacy Of A Childhood Lead Poisoning Risk Model As An Accurate Predictor Of Lead Exposure, Christopher R. Rustin
Electronic Theses and Dissertations
Lead poisoning is a significant public health problem with paint from old housing exposing thousands of children and leading to negative health and social outcomes. Identifying the highest risk children exposed to lead is important to public health agencies. The purpose of this study was to evaluate and assess the efficacy of a new geographically-based lead risk model that when combined with a child's physical address, predicts the extent of a child's risk of lead poisoning on a numeric risk scale. This model is unique because it calculates risk at the address level from parcel attributes of age and type …

Epidemiology Of Hospital Acquired Methicillin Resistant Staphylococcus Aureus In A Veterans Affairs Medical Center Spinal Cord Injury Unit: Fiscal Years 2008-2011, Rebecca B. Stone
Electronic Theses and Dissertations
The purpose of this retrospective case-control study was to assess risk factors contributing to hospital acquired methicillin Staphylococcus aureus (HA-MRSA) and gain a better understanding of the burden of HA-MRSA infection in patients with spinal cord injuries. The study was also conducted to see if new information would be found on HA-MRSA infections and validate or refute current research for patients in a dedicated spinal cord injury unit at a Veterans Affairs Medical Center. During the study period, the infection control department identified 95 cases of HA-MRSA. Additional data retrospectively collected were basic demographics, admitting diagnosis, presence of varying comorbidities, …
