Statistical Methods For The Analysis And Development Of Quantitative Imaging Biomarkers

The field of neuroimaging statistics is concerned with elucidating meaningful conclusions from high-dimensional imaging objects, often in the form of single-dimensioned summary statistics. Ideally, these summaries should provide interpretable biomarker measurements that can guide patient diagnoses or treatment decisions while minimizing information loss associated with dimension reduction. This dissertation is focused on (1) exploring methods for analyzing previously developed imaging biomarkers and (2) developing new imaging biomarkers using both well-established and novel imaging analysis techniques. We approach this problem in three ways: in our first project, we assess how previously developed imaging biomarkers can best be incorporated into downstream analyses in the context of a clinical trial. This work conceptualizes imaging biomarkers as measurements which intrinsically contain historical information on a patient and examines the effect of incorporating these predictors on the statistical power in a clinical trial analysis. For our second project, we develop a radiomic predictor that automatically identifies an important prognostic biomarker in multiple sclerosis, relying on quantification of imaging patterns potentially associated with brain atrophy and more severe disease courses. In our third project, we construct a coordinate system and framework for multiple sclerosis lesions analyses for more sensitive and specific biomarker development. We use dimension reduction and flexible nonparametric modelling to assess the diagnostic value of this method. These methods lay the groundwork for improving future work developing and utilizing imaging biomarkers with imaging statistics

Application of an objective structured clinical examination to evaluate and monitor interns’ proficiency in hand hygiene and personal protective equipment use in the United States

Purpose This study was conducted to determine whether an objective structured clinical examination (OSCE) could be used to evaluate and monitor hand hygiene and personal protective equipment (PPE) proficiency among medical interns in the United States. Methods Interns in July 2015 (N=123, cohort 1) with no experience of OSCE-based contact precaution evaluation and teaching were evaluated in early 2016 using an OSCE for hand hygiene and PPE proficiency. They performed poorly. Therefore, the new interns entering in July 2016 (N=151, cohort 2) were immediately tested at the same OSCE stations as cohort 1, and were provided with feedback and teaching. Cohort 2 was then retested at the OSCE station in early 2017. The Mann-Whitney U-test was used to compare the performance of cohort 1 and cohort 2 on checklist items. In cohort 2, performance differences between the beginning and end of the intern year were compared using the McNemar chi-square test for paired nominal data. Results Checklist items were scored, summed, and reported as percent correct. In cohort 2, the mean percent correct was higher on the posttest than on the pretest (92% vs. 77%, P<0.0001), and the passing rate (100% correct) was also significantly higher on the posttest (55% vs. 16%). At the end of intern year, the mean percent correct was higher in cohort 2 than in cohort 1 (95% vs. 90%, P<0.0001), and 55% of cohort 2 passed (a perfect score) compared to 24% in cohort 1 (P<0.0001). Conclusion An OSCE can be utilized to evaluate and monitor hand hygiene and PPE proficiency among interns in the United States
