Peer-reviewed work, a conference presentation, and an open portfolio of the methods behind it.
Peer-reviewed publications
Evaluation of COVID-19 Diagnosis Codes for Identification of SARS-CoV-2 Infections in a Nursing Home Cohort, 2022–2023
Patel A, Payne AB, Currie DW, et al. Journal of the American Medical Directors Association (JAMDA), 2024.
DOI: 10.1016/j.jamda.2024.105440
A validation study assessing how well COVID-19 diagnosis codes identify true SARS-CoV-2 infections in a nursing home cohort, evaluating diagnostic criteria against a gold-standard confirmatory endpoint. The methodology is directly analogous to interim monitoring of accumulating data against predefined criteria.
Effectiveness of COVID-19 Bivalent Vaccination Against SARS-CoV-2 Infection Among Residents of US Nursing Homes
Hatfield K, Wiegand R, Reddy S, Patel A, et al. Vaccine, 2024.
A real-world vaccine effectiveness study using Cox proportional hazards modeling and time-dependent exposure analysis across a large claims-based nursing home cohort.
Conference presentation
HCV Epidemiology and Risk Factor Analysis Using Real-World EHR Data
FCEP (Florida College of Emergency Physicians) Annual Conference, 2019.
Findings from a retrospective study of 2,000+ patients using real-world EHR data to identify epidemiologic risk factors for Hepatitis C infection, conducted while at Tampa General Hospital.
Open research code
I maintain a public GitHub repository mirroring the methodology behind the JAMDA and Vaccine papers above, with simulated R scripts and figures reproducing the analytic approach on non-identifiable data.
