ArticlePublication 2023Performance of Rapid Antigen Tests to Detect Symptomatic and Asymptomatic SARS-CoV-2 Infection
The objective of this study was to evaluate the performance of rapid antigen tests (Ag-RDTs) …
The objective of this study was to evaluate the performance of rapid antigen tests (Ag-RDTs) for detection of SARS-CoV-2 among symptomatic and asymptomatic participants. The general findings were that the performance of Ag-RDTs was optimized when asymptomatic participants tested 3 times at 48-hour intervals and when symptomatic participants tested 2 times separated by 48 hours. Participants completed Ag-RDTs and reverse transcriptase polymerase chain reaction (RT-PCR) testing for SARS-CoV-2 every 48 hours for 15 days. They…

ArticlePublication 2020Variation in False-Negative Rate of Reverse Transcriptase Polymerase Chain Reaction-Based SARS-CoV-2 Tests by Time Since Exposure
This study aimed to determine the false-negative rate of RT-PCR tests for SARS-CoV-2 infection based …
This study aimed to determine the false-negative rate of RT-PCR tests for SARS-CoV-2 infection based on the timeline of exposure and symptom onset. Drawing from data in seven studies involving 1,330 upper respiratory tract samples, a Bayesian model was used to estimate these rates. Findings showed that in the initial four days prior to typical symptom onset, the false-negative rate decreased from 100% on day 1 to 67% on day 4. By the day of…

ArticlePublication 2023Achieving the Cancer Moonshot Goal
The Cancer Moonshot seeks to reduce age-standardized cancer mortality rates by at least 50% over …
The Cancer Moonshot seeks to reduce age-standardized cancer mortality rates by at least 50% over the next 25 years. This article estimates trends in U.S. cancer mortality for all cancers and the six leading types and reviews opportunities to prevent, detect, and treat these common cancers.

ArticlePublication 2020Data-Driven Management of Post-Transplant Medications
Organ-transplanted patients typically receive high amounts of immunosuppressive drugs as a mechanism to reduce their …
Organ-transplanted patients typically receive high amounts of immunosuppressive drugs as a mechanism to reduce their risk of organ rejection. However, because of the diabetogenic effect of these drugs, this practice exposes them to a greater risk of new-onset diabetes after transplantation (NODAT), and hence, becoming insulin dependent. This study develops effective medication management strategies to address the common conundrum of balancing the risk of organ rejection versus that of NODAT. The article presents a robust…

ArticlePublication 2022Cost-Effectiveness of Masked Hypertension Screening and Treatment
The study assessed the health and economic outcomes of screening and treating masked hypertension in …
The study assessed the health and economic outcomes of screening and treating masked hypertension in U.S. adults using the Cardiovascular Disease (CVD) Policy Model, a microsimulation model. The model simulated 100,000 adults suspected of having masked hypertension (office blood pressure [BP] of 120–129/<80 mm Hg, not on antihypertensive medications, and without a history of CVD). Interventions included: usual care alone, usual care with ambulatory BP monitoring (ABPM), and usual care with home BP monitoring (HBPM).…

ArticlePublication 2021BMI-Related Healthcare Costs in the U.S.
This paper estimates continuous body mass index (BMI) related health care expenditures using data from …
This paper estimates continuous body mass index (BMI) related health care expenditures using data from the Medical Expenditure Panel Survey (MEPS) 2011-2016, adjusting BMI for self-report bias and controlling for potential confounding between BMI and medical expenditures. Costs are reported in $US 2019. The analysis found a J-shaped curve of medical expenditures by BMI, with higher costs for females and the lowest expenditures occurring at a BMI of 20.5 for adult females and 23.5 for…

ArticlePublication 2022Duration & Cost-Effectiveness of Hepatocellular Carcinoma Surveillance in Hepatitis C Patients After Viral Eradication
This study assesses the cost-effectiveness of biannual surveillance for hepatocellular carcinoma (HCC) in patients cured …
This study assesses the cost-effectiveness of biannual surveillance for hepatocellular carcinoma (HCC) in patients cured of hepatitis C virus (HCV) using oral direct-acting antivirals (DAAs). A microsimulation model of HCC natural history in individuals with HCV-related advanced fibrosis or cirrhosis post-DAAs was developed, integrating data on HCC incidence, tumor progression, surveillance adherence, and health state costs/utilities. Biannual ultrasound and alpha-fetoprotein surveillance were compared to no surveillance over varying durations (5 years to lifetime). Results indicate…

This economic evaluation assesses the cost-effectiveness of atrial fibrillation (AF) screening strategies, particularly utilizing wrist-worn …
This economic evaluation assesses the cost-effectiveness of atrial fibrillation (AF) screening strategies, particularly utilizing wrist-worn wearable devices, to prevent strokes. Conducted using a microsimulation decision-analytic model, the study spans from September 8, 2020, to May 23, 2022, incorporating 30 million simulated individuals representative of the US population aged 65 years or older. Eight screening strategies, including six employing wrist-worn devices and two using traditional methods, were compared against no screening. Results indicate that all wrist-worn…

ArticlePublication 2021Cost-Effectiveness of Hypertension Treatment by Pharmacists in Black Barbershops
The Los Angeles Barbershop Blood Pressure Study (LABBPS) examined the effectiveness and cost of a …
The Los Angeles Barbershop Blood Pressure Study (LABBPS) examined the effectiveness and cost of a one-year pharmacist-led hypertension care intervention in Black-owned barbershops in Los Angeles County, focused on non-Hispanic Black men with uncontrolled hypertension. Using a discrete event simulation, the researchers projected the 10-year health outcomes and health care costs associated with the intervention compared to a control group. The costs and quality-adjusted life-years (QALYs) were calculated from a health care sector perspective, with…
