Executive summary: the 2018 Academic Emergency Medicine Consensus Conference: Aligning the Pediatric Emergency Medicine Research Agenda to Reduce Health Outcome Gaps.
Emergency care providers share a compelling interest in developing an effective patient-centered, outcomes-based research agenda that can decrease variability in pediatric outcomes. The 2018 Academic Emergency Medicine Consensus Conference "Aligning the Pediatric Emergency Medicine Research Agenda to Reduce Health Outcome Gaps (AEMCC)" aimed to fulfill this role. This paper discusses the conference which convened major thought leaders and stakeholders to introduce a research, scholarship, and innovation agenda for pediatric emergency care specifically to reduce health outcome gaps.

Extension of disease risk score-based confounding adjustments for multiple outcomes of interest: an empirical evaluation.
Use of disease risk score (DRS)-based confounding adjustment when estimating treatment effects on multiple outcomes is not well studied. In this empirical cohort study, the investigators compared dabigatran initiators and warfarin initiators with respect to risks of ischemic stroke and major bleeding in 12 sequential monitoring periods (90 days each), using data from the Truven Marketscan database (Truven Health Analytics, Ann Arbor, Michigan).

Race/ethnicity and retention in traumatic brain injury outcomes research: a traumatic brain injury model systems national database study.
The purpose of this study was to investigate the contribution of race/ethnicity to retention in traumatic brain injury (TBI) research at 1 to 2 years postinjury. The findings emphasized the importance of investigating retention rates separately for blacks and Hispanics rather than combining them or grouping either with other races or ethnicities. The results also suggested the need for implementing procedures to increase retention of Hispanics in longitudinal TBI research.

Quantification of long-term survival benefit in a comparative oncology clinical study.
The authors discuss the quantification of long-term survival benefit in a comparative oncology clinical study. They assert that from the perspective of cost-risk-benefit, using a long-term survival benefit criterion for selecting anticancer therapies may be more appropriate.

Towards global consensus on core outcomes for hidradenitis suppurativa research: an update from the HISTORIC consensus meetings I and II.
This article describes the outcome of two in-person consensus meetings to create a core outcomes set (COS) for hidradenitis suppurative (HS) research. Forty-one individuals from 13 countries and 4 continents were included. The list of items discussed had been developed from patient interviews, a systematic literature review and a healthcare professional survey. Nine items were excluded and seven domains were approved which included: disease course, physical signs, HS-specific quality of life, satisfaction, symptoms, pain and global assessments.

Sample size calculations for time-averaged difference of longitudinal binary outcomes.
In this study, the researchers investigated sample size calculation for the comparison of time-averaged responses between treatment groups in clinical trials with longitudinally observed binary outcomes. Their simulation showed that the nominal power and type I error are well preserved over a wide range of design parameters. The researchers believe that theirs is the first study to consider the mixture of missing patterns in sample size calculation.

Protocol for the development of a core domain set for hidradenitis suppurativa trial outcomes.
A COS is a list of outcomes that are meant as mandatory and should be measured and reported in all clinical trials. The aim of this study is to develop a COS for the management of the chronic, inflammatory skin disease hidradenitis suppurativa (HS). An international steering group of researchers, clinicians, and a patient research partner will guide the COS development.

Preface to the AHRQ supplement.
AHRQ, through its Developing Evidence to Inform Decisions about Effectiveness (DEcIDE) Research Network, sponsored this supplement to present various strategies in the design, analysis, and conduct of health outcomes studies relevant to rare diseases. The purpose of this supplement is to disseminate illustrative examples of research methods that can be applied to understand health outcomes and potentially to stimulate new patient-centered outcomes studies for rare diseases.

Potential bias of instrumental variable analyses for observational comparative effectiveness research.
Results of instrumental variable analyses may be biased if the instrument and outcome are related through an unadjusted third variable, an instrument-outcome confounder. The authors review of 187 comparative effectiveness studies using this type of analysis, only 4 considered potential instrument-outcome confounders outside the study data.

Elective induction of labor symposium: nomenclature, research methodological issues, and outcomes.
This article focuses on key method issues in studies of elective induction of labor. The authors first identify methodological concerns with the existing literature and discuss each in return. They then review existing evidence about the relationship between elective induction and cesarean delivery.

Overview of classical test theory and item response theory for the quantitative assessment of items in developing patient-reported outcomes measures.
This article presents an overview of classical test theory and item response theory in the quantitative assessment of items and scales during the content-validity phase of patient-reported outcomes (PRO) measure development. The researchers concluded that depending on the particular type of measure and specific circumstances, either approach or both may be useful to help maximize the content validity of a PRO measure.
