The application of social network analysis to the organization of healthcare delivery is a relatively new area of research that may not be familiar to health services statisticians and other methodologists. We present a methodological introduction to social network analysis with a case study of physicians’ adherence to clinical guidelines regarding use of implantable cardioverter defibrillators (I...... hiện toàn bộ
The effects of rurality on mental and physical healthHealth Services and Outcomes Research Methodology - Tập 10 - Trang 33-66 - 2010

The effects of rurality on physical and mental health are examined in analyses of a national dataset, the Community Tracking Survey, 2000–2001, that includes individual level observations from household interviews. We merge it with county level data reflecting community resources and use econometric methods to analyze this multi-level data. The statistical analysis of the impact of the choice of d...... hiện toàn bộ
Nonparametric estimation of population average dose-response curves using entropy balancing weights for continuous exposuresHealth Services and Outcomes Research Methodology - Tập 21 - Trang 69-110 - 2021

Weighted estimators are commonly used for estimating exposure effects in observational settings to establish causal relations. These estimators have a long history of development when the exposure of interest is binary and where the weights are typically functions of an estimated propensity score. Recent developments in optimization-based estimators for constructing weights in binary exposure sett...... hiện toàn bộ
Semi-parametric regression as a tool for assessing moderation: an analysis of the Fast Track interventionHealth Services and Outcomes Research Methodology - Tập 10 - Trang 67-85 - 2010
E. Michael Foster, Stephanie Watkins
When assessing the impact of a family or youth intervention, program evaluators often consider whether and how baseline characteristics moderate the effect of treatment. Parametric and non-parametric approaches are both possible, but each has limitations. In this article, we argue for and illustrate the use of semi-parametric methods. A hybrid of parametric and non-parametric approaches, semi-para...... hiện toàn bộ
A tutorial on selecting and interpreting predictive models for ordinal health-related outcomesHealth Services and Outcomes Research Methodology - Tập 15 - Trang 223-240 - 2015
Maria Guzman-Castillo, Sally Brailsford, Michelle Luke, Honora Smith
Ordinal variables are very often objects of study in health sciences. However, due to the lack of dissemination of models suited for ordinal variables, users often adopt other practices that result in the loss of statistical power. In this tutorial, different models from the family of logistic regression models are introduced as alternatives to handle and interpret ordinal outcomes. The models tha...... hiện toàn bộ

At the 2018 International Conference on Health Policy Statistics (ICHPS) held in Charleston, South Carolina, Anirban Basu was awarded the Mid-Career Excellence Award from the American Statistical Association Section on Health Policy Statistics (HPSS). Anirban was exceptionally and uniquely qualified for this award. Highlights include his providing outstanding service to the HPSS, advancing statist...... hiện toàn bộ
Bias and variance trade-offs when combining propensity score weighting and regression: with an application to HIV status and homeless menHealth Services and Outcomes Research Methodology - Tập 12 - Trang 104-118 - 2012

The quality of propensity scores is traditionally measured by assessing how well they make the distributions of covariates in the treatment and control groups match, which we refer to as “good balance”. Good balance guarantees less biased estimates of the treatment effect. However, the cost of achieving good balance is that the variance of the estimates increases due to a reduction in effective sa...... hiện toàn bộ
