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…

ArticlePublication 2020Bayes' Theorem, COVID-19, and Screening Tests
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain …
This article reviews the implications of increased testing for COVID-19 using reverse transcriptase polymerase chain reaction (rRT-PCR) through the application of Bayes’ Theorem for three hypothetical, stylized case scenarios. The scenarios involve three patients with a low, moderate, and high pre-test probability of COVID-19 infection. The category of low probability would include "asymptomatic individuals in a presumed low prevalence environment" and might vary from 10 to 20%. The category of moderate probability would include "individuals…

Tools/ModelsInteractive, Teaching Resource 2020Interactive Graphic: Interpreting a COVID-19 Test Result
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction …
Currently, the most common diagnostic test for COVID-19 relies on reverse transcriptase polymerase chain reaction (RT-PCR), and most often uses samples obtained from the respiratory tract by nasopharyngeal swab. This interactive graphic demonstrates the influence of the prior probability of COVID-19, the test sensitivity (i.e., the probability of a positive test conditional on disease presence), and the test specificity (i.e., the probability of a negative test conditional on disease absence) on the post-test probability of…

ArticlePublication 2019Long-Term Cost-Effectiveness of Obesity Prevention Interventions in the Early Years of Life
This analysis estimated the long-term health benefits and health care cost-savings of reductions in body …
This analysis estimated the long-term health benefits and health care cost-savings of reductions in body mass index (BMI) for the Australian population of children aged between 2 and 5 years. A proportional multistate, multiple cohort, lifetable model estimated the health benefits and health care cost-savings related to hypothetical reductions in BMI, informed by a scoping review of systematic reviews reporting the effectiveness of obesity prevention interventions in preschool aged children. Results suggested significant potential for…

ArticlePublication 2020Clinical Decision Making: Using a Diagnostic Test
This article is part of a 6-part series on clinical decision making. The authors use …
This article is part of a 6-part series on clinical decision making. The authors use two clinical examples to review the principles of interpreting diagnostic test results. They outline an approach that can be used to determine how to select and apply tests and their results to the practice of internal medicine. Topics covered in the two case studies include sensitivity and specificity, positive predictive and negative predictive value of tests, and how to estimate…

ArticlePublication 2019Cost-Effectiveness of Clinic, Home, or Ambulatory Blood Pressure Measurement for Hypertension Diagnosis
This study compared three methods of blood pressure (BP) measurement for diagnosing hypertension in primary …
This study compared three methods of blood pressure (BP) measurement for diagnosing hypertension in primary care settings, accounting for the possibility of false-positive (white-coat hypertension) and false-negative (masked hypertension) clinic measurements. Outcomes included quality-adjusted life years (QALYs) and lifetime costs associated with clinic BP measurement, home BP monitoring, and ambulatory blood pressure monitoring (ABPM) under two scenarios: positive and negative initial screening. Data were from published literature, public data sources, and expert input. In the…

ArticlePublication 2019Country Contextualization of Cost-Effectiveness Studies
This article, published in BMJ Global Health, provides experiences of country contextualization of WHO-CHOICE methods …
This article, published in BMJ Global Health, provides experiences of country contextualization of WHO-CHOICE methods and models to a country level. Results from three contextualized cost-effectiveness analyses (CEAs) are presented, and the authors discuss how this evidence can inform priority setting in Ethiopia. This method of contextualized CEAs requires inclusion of national analysts and use of country-specific inputs for either costs, epidemiology, demography, baseline coverage or effects. Rank ordering of interventions by incremental cost-effectiveness ratios…

This chapter is part of a report entitled, Decision and Simulation Modeling in Systematic Reviews, that seeks …
This chapter is part of a report entitled, Decision and Simulation Modeling in Systematic Reviews, that seeks to provide guidance for determining when incorporating a decision-analytic model alongside a systemic review would be of added value for decision making purposes. The chapter discusses the role of decision analysis and decision-analytic models in health care, specifically within the context of the current emphasis on evidence-based medicine and the proliferation of systematic reviews. It describes the types of model available…

This article aimed to compare the health and economic impact of 3 services recommended by …
This article aimed to compare the health and economic impact of 3 services recommended by the US Preventive Services Task Force for the primary prevention of cardiovascular disease (CVD): (1) aspirin counseling for the primary prevention of CVD and colorectal cancer, (2) screening and treatment for lipid disorders (usually high cholesterol), and (3) screening and treatment for hypertension. A microsimulation model was used to compare lifetime outcomes from the societal perspective for a US-representative birth…
