Dr. Angela Presson is a Research Associate Professor in the Division of Epidemiology in the Department of Internal Medicine at the University of Utah. She also holds adjunct appointments in the Department of Pediatrics (Pediatric Critical Care), Department of Orthopaedics and Department of Population Health Sciences (Biostatistics); and an adjunct appointment in the University of California, Los Angeles (UCLA)’s Department of Biostatistics. Prior to starting at the University of Utah, she was a full-time Adjunct Assistant Professor in Biostatistics and Pediatrics at UCLA (2007-2010). She has a PhD from the UCLA Department of Statistics and a BS in Biological Sciences from Cornell University.

Research Statement

My research career began at UCLA in the area of statistical genetics, where both my dissertation research and early career research focused on this topic. More recently, I have collaborated with faculty in Orthopaedics and Surgery, where there is interest in studying patient outcomes both in terms of comparative effectiveness of treatments and patient satisfaction with care. The following research topics are summarized below with selected publications.

Statistical Genetics – Early in my research career I developed MicroMerge software (Presson et al. 2006, 2008) and identified genetic predictors of chronic fatigue syndrome using weighted network analysis WNA (Presson et al. 2008). MicroMerge is freely available software that implements a Bayesian Markov Chain Monte Carlo method to merge microsatellite marker data sets generated on different genotyping platforms (http://www.genetics.ucla.edu/software/micromerge). I have also developed methodology for identifying integration site patterns of gene therapy vectors to evaluate their safety (Presson et al. 2011). At the University of Utah, I have collaborated with clinical scientists to apply WNA methods to the discovery of phenotypes in Acute Respiratory Distress Syndrome (Brown et al. 2017).

Comparative Effectiveness & Patient Outcomes Research – To evaluate patient outcomes following surgical techniques in observational research, it is becoming increasingly popular to apply causal inference methods such as propensity scores (Brooke et al. 2017, Scaife et al. 2018, Dy et al. 2018) and marginal structural models (Patel et al. 2017). The gold standard approach for evaluating pre/post study designs is to use segmented regression models when data is available at the patient level (Tonna et al. 2018) or interrupted time-series analysis to aggregated data. For example, see the pre/post study quality checklist from the NIH https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools.

Assessment of Patient Satisfaction –Much of my recent research has been in collaboration with faculty in the Departments of Surgery and Orthopaedics on studies that evaluate patient satisfaction outcomes. Specifically, we have studied the psychometric properties of the Press Ganey® satisfaction survey, which is used to evaluate patient satisfaction at the University of Utah (Presson et al. 2017). We have also published on patient characteristics associated with satisfaction (Abtahi et al. 2015, Martin et al. 2017, Tyser et al. 2018), and evidence of non-response bias on the the Press Ganey® satisfaction survey (Tyser et al. 2016).
