The NIH Pragmatic Trials Collaboratory supports the design and conduct of 31 embedded pragmatic clinical trials, and many of these trials use patient-reported outcome measures (PROMs) to provide valuable information about their patients' health and wellness. Often these trials enroll medically underserved patients, including people with incomes below the federal poverty threshold, racial or ethnically minoritized groups, or rural or frontier communities. In this series of trial case reports, we provide lessons learned about collecting PROMs in these populations.

Article Synopsis
  • The study analyzed immune-related cytokines and chemokines to see if they can predict disease activity in patients with localized scleroderma (LS).
  • Researchers collected 194 serum samples from 45 LS patients with different forms of the disease, finding that certain cytokines like IP-10 and TNF-α were significantly elevated during active disease states.
  • The analysis identified IP-10, TNF-α, and MCP-1 as reliable predictors of active disease, which could help in making clinical decisions when evaluating disease activity is difficult.

The NIH Pragmatic Trials Collaboratory supports the design and conduct of 27 embedded pragmatic clinical trials, and many of the studies collect patient reported outcome measures as primary or secondary outcomes. Study teams have encountered challenges in the collection of these measures, including challenges related to competing health care system priorities, clinician's buy-in for adoption of patient-reported outcome measures, low adoption and reach of technology in low resource settings, and lack of consensus and standardization of patient-reported outcome measure selection and administration in the electronic health record. In this article, we share case examples and lessons learned, and suggest that, when using patient-reported outcome measures for embedded pragmatic clinical trials, investigators must make important decisions about whether to use data collected from the participating health system's electronic health record, integrate externally collected patient-reported outcome data into the electronic health record, or collect these data in separate systems for their studies.

Background & Objectives: Spontaneous intracranial hypotension (SIH) is an underdiagnosed and debilitating condition caused by a spinal cerebrospinal fluid (CSF) leak. Although SIH can lead to substantial morbidity and disability, little data exists about patients' perspectives. Without hearing directly from patients, our understanding of the full experience of having SIH is limited, as is our ability to identify and use appropriate patient-reported outcome measures (PROMs) within clinical care and research.

Article Synopsis
  • - Embedded pragmatic clinical trials (ePCTs) are important for tackling current health issues, leveraging electronic health records (EHRs) for quicker and more extensive research.
  • - As ePCTs increase, there's a growing concern that biases may arise from uneven data capture and healthcare access, which can worsen health inequalities.
  • - The text highlights three main challenges: inconsistent data on social factors, limited representation of underserved groups, and technology-related data loss, along with suggestions to reduce these biases.

Embedded pragmatic clinical trials (ePCTs) are conducted during routine clinical care and have the potential to increase knowledge about the effectiveness of interventions under real world conditions. However, many pragmatic trials rely on data from the electronic health record (EHR) data, which are subject to bias from incomplete data, poor data quality, lack of representation from people who are medically underserved, and implicit bias in EHR design. This commentary examines how the use of EHR data might exacerbate bias and potentially increase health inequities.

Communication deficits have a substantial impact on quality of life for individuals with Angelman syndrome (AS) and their families, but limited qualitative work exists to support the necessary content of measures aiming to assess communication for these individuals. Following best practices for concept elicitation studies, we conducted individual qualitative interviews with caregivers and clinicians to elicit meaningful aspects of communication for individuals with AS. Caregivers were able to discuss their child's specific communication behaviors within a large number of expressive, receptive, and pragmatic functions via numerous symbolic and non-symbolic modalities.

There is a critical need for high-quality clinical outcome assessments to capture the important aspects of communication ability of individuals with Angelman syndrome (AS). To center the perspective of caregivers, our team developed the novel Observer-Reported Communication Ability (ORCA) measure using best practice guidelines, with the goal of developing a measure that could be administered to caregivers directly without the need for a certified administrator for use in clinical trials. To refine the draft measure, we conducted two rounds of cognitive interviews with 24 caregivers and a quantitative study including 249 caregivers.

For children with pediatric rheumatic diseases (PRDs), the inclusion of patient-reported outcomes (PROs) is critical to inform decision making in health care delivery and research settings. PROs are direct reports from a child on their health status, without interpretation by anyone else. PROs improve understanding of the patient experience, allow clinicians to provide patient-centered care, and add value to clinical trials.

Background: Training opportunities to pursue a career in pediatric rehabilitation medicine (PRM) have evolved over the last 40 years, with the most recent change being the development and accreditation of PRM fellowships and subspecialty certification in PRM. Currently the American Board of Physical Medicine & Rehabilitation (ABPMR) requires all candidates for PRM subspecialty certification to have completed a physical medicine and rehabilitation (PM&R) residency. The small number of certified PRM physicians has prompted debate within the field about permitting pediatricians to enter PRM fellowships without having to complete a PM&R residency.

Purpose: Anchoring vignettes (AVs) are a promising measurement technique to reduce bias in patient-reported outcome (PRO) measures by helping researchers understand differences in how individuals and groups interpret response options. However, little attention has been paid to ensure quality development of AVs, and their performance has not been well assessed in pediatric populations. In this study, we explore the application of a rigorous development process for AVs based upon current standards for PROs, as well as feasibility of AVs when administered to children and adolescents.

Unexplained heterogeneity in outcomes following pediatric traumatic brain injury (TBI) is one of the most critical barriers to the development of effective prognostic tools and therapeutics. The addition of personal biological factors to our prediction models may account for a significant portion of unexplained variance and advance the field toward precision rehabilitation medicine. The overarching goal of the Epigenetic Effects on Pediatric Traumatic Brain Injury Recovery (EETR) study is to investigate an epigenetic biomarker involved in both childhood adversity and postinjury neuroplasticity to better understand heterogeneity in neurobehavioral outcomes following pediatric TBI.
