The Use and Interpretation of Quasi-Experimental Studies in Medical Informatics
Anthony D. Harris,Jessina C. McGregor,Eli N. Perencevich,Eli N. Perencevich,Jon P. Furuno,Jingkun Zhu,Dan E. Peterson,Joseph Finkelstein +7 more
TL;DR: It is hoped that future medical informatics studies will implement higher level quasi-experimental study designs that yield more convincing evidence for causal links between medical informatic interventions and outcomes.
Journal ArticleDOI
Predictors of 30-Day Mortality among Patients with Pseudomonas aeruginosa Bloodstream Infections: Impact of Delayed Appropriate Antibiotic Selection
Thomas P. Lodise,Nimish Patel,Andrea L. Kwa,Jeffrey Graves,Jon P. Furuno,Eileen M. Graffunder,Ben M. Lomaestro,Jessina C. McGregor +7 more
TL;DR: The data strongly suggest that delaying appropriate therapy for approximately 2 days significantly increases the risk of 30-day mortality in patients with P. aeruginosa bloodstream infections.
Journal ArticleDOI
Comparative effectiveness of nafcillin or cefazolin versus vancomycin in methicillin-susceptible Staphylococcus aureus bacteremia
Marin L. Schweizer,Marin L. Schweizer,Jon P. Furuno,Anthony D. Harris,J. Kristie Johnson,Michelle Shardell,Jessina C. McGregor,Kerri A. Thom,Sara E. Cosgrove,George Sakoulas,George Sakoulas,Eli N. Perencevich,Eli N. Perencevich +12 more
TL;DR: Receipt of nafcillin or cefazolin was protective against mortality compared to vancomycin even when therapy was altered after culture results identified MSSA.
Journal ArticleDOI
Utility of the Chronic Disease Score and Charlson Comorbidity Index as Comorbidity Measures for Use in Epidemiologic Studies of Antibiotic-resistant Organisms
Jessina C. McGregor,Peter W. Kim,Eli N. Perencevich,Douglas D. Bradham,Jon P. Furuno,Keith S. Kaye,Jeffrey C. Fink,Patricia Langenberg,Mary Claire Roghmann,Anthony D. Harris +9 more
TL;DR: A revised comorbidity measure specific to resistant infections would likely provide a better assessment of the comor bidity-attributable risk of antibiotic-resistant infections.
Journal ArticleDOI
Risk Factors for Colonization with Extended-Spectrum β-Lactamase–producing Bacteria and Intensive Care Unit Admission
Anthony D. Harris,Jessina C. McGregor,Judith A. Johnson,Sandra M. Strauss,Anita C. Moore,Harold C. Standiford,Joan N. Hebden,J. Glenn Morris +7 more
TL;DR: Coexisting conditions and previous antimicrobial drug exposure predict colonization.
