A Review of Causal Inference Methods for Estimating the Effects of Exposure Change when Incident Exposure Is Unobservable
AbstractPurpose of ReviewResearch questions on exposure change and health outcomes are both relevant to clinical and policy decision making for public health. Causal inference methods can help investigators answer questions about exposure change when the first or incident exposure is unobserved or not well defined. This review aims to help researchers conceive of helpful causal research questions about exposure change and understand various statistical methods for answering these questions to promote wider adoption of causal inference methods in research on exposure change outside the field of pharmacoepidemiology.Recent F...

The Clone-Censor-Weight Method in Pharmacoepidemiologic Research: Foundations and Methodological Implementation
AbstractPurpose of ReviewOver the past two decades, cautions have repeatedly been issued about the potential for immortal time bias in observational studies. This bias is particularly relevant in fields that routinely leverage large secondary databases such as pharmacoepidemiology. A variety of study design and analysis tools exist to prevent immortal time bias. A newer approach, the clone-censor-weight method, successfully eliminates the possibility for immortal time while maintaining a target trial emulation framework. We review the rationale for the clone-censor-weight approach, outline the steps for implementation, com...

Community Health Fairs and Cancer Prevention in Low-Resource Settings: A Global Perspective
AbstractPurpose of ReviewHealth fairs could increase screening uptake and ultimately contribute to reducing inequalities in cancer outcomes between low- and middle-income countries (LMIC) and developed countries. Reviews on this topic have been limited to health fairs in the USA. In this paper, we review the scientific literature for evidence that support health fairs as a strategy to improve cancer prevention.Recent FindingsStudies across the USA consistently reported that health fairs were effective in providing cancer education and screening tests to historically marginalized groups. The studies reviewed were mostly obs...

Using Counterfactual Worlds to Triangulate Evidence in the Real World
AbstractPurpose of ReviewWhen a causal question can be reasonably approached using more than one set of causal assumptions (i.e., using different identification strategies), triangulation can be used to compare estimates relying on these different assumption sets to gain insight into the validity of the causal assumptions used. This review covers the current understanding of triangulation from a counterfactual causal inference perspective.Recent FindingsWe use counterfactuals to clarify and supplement the current understanding of triangulation. We propose a counterfactual definition of triangulation, propose assumptions on...

Current Approaches to Measuring Local Racial and Ethnic Residential Segregation in Population Health Studies
AbstractPurpose of ReviewSegregation has traditionally been measured at the metropolitan area or county level, but a growing number of population health studies have measured segregation at the neighborhood or local level. In this review, we highlight the ways local racial and ethnic residential segregation has been measured in recently published population health studies (June 1, 2019 –June 30, 2022).Recent FindingsWe identified 40 local segregation studies based on our search criteria. The majority used racial or ethnic composition to measure segregation, but several additional measures were identified that reflect dif...
