Comparing approaches to identify live births using the Transformed Medicaid Statistical Information System.
The objective of this study was to evaluate the performance of five approaches to identifying live births using Transformed Medicaid Statistical Information System Analytic Files (TAF). The approaches each used a different combination of diagnosis and procedure, revenue, and place of service codes to identify live births. The findings showed that Approach 4 achieved the best match of birth counts relative to CDC birth record data; Approaches 1 and 3 resulted in overcounts of births and Approaches 2 and 5 resulted in undercounts. The authors concluded that including claims from both inpatient and other services files, and excluding codes unrelated to the delivery episode, improved accuracy of live birth identification in the TAF data.

Estimating subgroup effects in generalizability and transportability analyses.
The purpose of this article was to recommend methods for estimating subgroup-specific potential outcome means and average treatment effects in generalizability and transportability analyses, utilizing outcome model--based, weighting, and augmented weighting estimators. To exemplify this process, the authors applied the methods to data from the Coronary Artery Surgery Study (North America, 1975-1996) to compare the effect of surgery plus medical therapy vs. only medical therapy for chronic coronary artery disease in subgroups defined by history of myocardial infarction.

Integrating transformative considerations and quantitative results through a participant selection joint display in explanatory sequential mixed methods studies.
This article presents a method of integrating transformative sampling considerations in explanatory sequential designs through a participant selection joint display in explanatory sequential mixed methods studies. The presented approach addressed concerns regarding transparency of research decisions in these studies, while providing a method of centering the transformative paradigm in mixed methods integration procedures.

Integrating mixed methods in health services and delivery system research.
The authors introduced this AHRQ-sponsored issue of Health Services Research, describing the papers and briefly indicating where they fit into the emerging mixed methods mosaic. They then provided some suggestions about what may be missing and anticipated a future state of a more integrated approach to health services research and richer dialogue between researchers and those engaged in health care.

Building wave response rates in a longitudinal survey:Essential for nonsampling error reduction or last in–first out?
This study examined the implications of a reduction in targeted first-round response rates in the Medical Expenditure Panel Survey (MEPS), a national health care survey designed to produce estimates of health care utilization, expenditures, and insurance coverage. Study findings revealed nonuniform results when evaluating the capacity of alternative design strategies to achieve precision targets while simultaneously satisfying data collection budget constraints for a variety of medical care expenditure estimates.

The role of facility design in preventing the transmission of healthcare-associated infections: Background and conceptual framework.
This paper describes the conceptual framework and methodology used to conduct a comprehensive literature review of current evidence evaluating the role of the built environment in the transmission of healthcare-associated infections. The methodology involves a chain of transmission interventions model that is a multidisciplinary conceptualization of the interaction between pathogens and the built environment. This model facilitated a systematic literature review of a very large amount of data.

Survey of the methods and reporting practices in published meta-analyses of test performance: 1987 to 2009.
The researchers performed a survey of meta-analyses of test performance to describe the evolution in their methods and reporting. They found that the most common clinical areas were cardiovascular disease and oncology, while the most common test categories were imaging and biomarker tests. They concluded that the methods employed in meta-analyses of test performance have improved with the introduction of quality assessment checklists and the development of more sophisticated statistical methods.

Feasibility of feature-based indexing, clustering, and search of clinical trials. A case study of breast cancer trials from ClinicalTrials.gov.
Searching through a large collection of clinical trials using existing technology is a daunting task. This study extracted 1,437 eligibility features from 80 stage III breast cancer clinical trials and found that it is feasible to develop feature-based indexing and clustering methods for clinical trials to identify trials with similar target populations and to improve trial search efficiency.

How the Patient-Centered Outcomes Research Institute is engaging patients and others in shaping its research agenda.
This article describes PCORI's approach to generating topics for research and how it is being used in selection of research that PCORI will fund. It further describes challenges facing this approach, including a lack of common language and training on the part of patients and resistance on the part of researchers to questions that are not researcher generated.
