Grand Rounds June 16, 2023: BeatPain Utah: Partnering With Community Health Centers Within a Socio-Technical Framework (Julie Fritz, PT, PhD, FAPTA; Guilherme Del Fiol, MD, PhD)

Keywords

Key Points

  • Clinical practice guidelines support nonpharmacologic care as first-line management of low back pain. However, persons in low-income and rural communities have significantly higher odds of receiving a prescription opioid for a new back pain diagnosis.
  • Use of nonpharmacologic pain treatments is lower in rural settings and for persons of Hispanic/Latino ethnicity. Many of these communities are served by federally qualified health centers that often lack options to provide accessible nonpharmacologic alternatives.
  • Clinical research can exacerbate disparities, because clinical trials typically are based in urban, academic medical centers, underrepresent diverse populations, and overlook community engagement strategies in trial planning and design.
  • BeatPain Utah, an NIH Pragmatic Trials Collaboratory Trial, is an embedded pragmatic clinical trial comparing the effectiveness of nonpharmacologic intervention strategies for patients with back pain seeking care in federally qualified health centers in Utah. The interventions include a telehealth strategy that provides a brief pain teleconsult along with phone-based physical therapy, and an adaptive strategy that provides the brief pain teleconsult first, followed by phone-based physical therapy among patients who are nonresponsive to treatment.
  • BeatPain Utah is using the Community-Engaged Dissemination and Implementation (CEDI) framework, which considers both social and technical factors in the implementation of health IT strategies, decentralizes the research methods and procedures, and grounds the implementation in a systematic, iterative mapping of how both clinic staff and patients interact with health IT.
  • Although there is evidence of a significant divide in the implementation of advanced health IT functions, low-resource settings can adopt advanced health IT with some assistance. Moreover, there is considerable opportunity to reduce inequities through increased adoption of telehealth strategies, given that 96% of people in low-resource communities have at least a text and voice phone.

Discussion Themes

  • Motivating patients to engage in self-management of health conditions is a challenge, irrespective of whether the intervention is delivered in person or remotely.
  • Designing interventions that can meet everyone’s needs can be a challenge in a study that involves rural/urban and racial/ethnic diversity. Implementation mapping at the beginning of the design process is key. This includes direct assessment of patients’ needs, such as by interviewing patients who seek care in the partnering clinics to understand their expectations and how they would think about a mode of care delivery, like telehealth, that is unfamiliar to them.
  • Another crucial element of the health equity–focused model is ensuring that the question at the heart of the research is of value to the clinics and their leadership. For every trial, one of the first important tasks is to reach out to the community health center leadership and see if they are interested. The clinic’s priorities should drive the design of the trial. “We have to be very accommodating to the needs of each [community health center] and respect their needs.”
  • How quickly can these types of studies proceed from trial completion to release of results? Especially in studies involving chronic conditions, having long-term follow-up data to answer the core effectiveness question in a hybrid trial means there could be a long wait for results. Researchers must also be prepared to consider the question of sustaining a service that many clinics in the study have come to rely on, even before the results are available.

April 27, 2023: New Chapter Describes Intervention Delivery and Complexity

The NIH Pragmatic Trials Collaboratory published a new chapter of its Living Textbook of Pragmatic Clinical Trials this week. The chapter, “Intervention Delivery and Complexity,” illustrates that—although an intervention may be simple—the actual delivery of the intervention may be complex due to factors such as new workflows, special training of frontline staff, and the number of components in the intervention. This chapter reviews what makes an intervention’s delivery complex and frameworks and guidance for studying complex interventions.

The chapter also highlights an online Intervention Complexity Calculator developed by the NIH Pragmatic Trials Collaboratory to evaluate the complexity of delivery of a trial intervention. To develop the tool, principal investigators of embedded pragmatic clinical trials shared critical drivers of complexity that affected their ability to implement an intervention and discern treatment effects. The tool consists of 6 domains comprised of internal and external factors that can impact complexity.

Intervention Complexity Calculator

An article describing the tool and its development was also published in Contemporary Clinical Trials.

April 10, 2023: Li Receives New PCORI Award to Develop Causal Inference Methods for Stepped-Wedge Cluster Randomized Trials

Dr. Fan Li

Dr. Fan Li, a member of the NIH Pragmatic Trials Collaboratory’s Biostatistics and Study Design Core since 2013, has received approval of a 3-year funding award from the Patient-Centered Outcomes Research Institute (PCORI) to develop causal inference methods for stepped-wedge cluster randomized trials—a design that has been increasingly adopted in pragmatic trials. Li is an assistant professor of biostatistics at the Yale School of Public Health.

The new study, entitled “Toward Improved Design and Analysis of Stepped Wedge Trials: An Estimand-Aligned and Efficiency-Focused Framework,” will contribute new methods and software for planning and analyzing stepped-wedge cluster randomized trials that enable investigators to (a) target transparent causal estimands under the counterfactual outcomes framework and (b) to leverage baseline information for achieving higher statistical efficiency.

This is Li’s second PCORI award. Read a summary of his previous PCORI award.

An estimand is a precise description of the treatment effect reflecting the scientific question, and is ideally a model-free concept. The research team will contribute weighted average effect estimands to quantify treatment effect evidence by recognizing that unequal cluster sizes may contribute to variations of treatment effects in each cluster-period. In addition, pragmatic trials that adopt a stepped-wedge cluster randomized design frequently collect baseline data on the patient-centered outcomes and/or patient-level characteristics. The research team will study and operationalize estimand-aligned methods that effectively leverage such baseline variables through parametric regression and nonparametric machine learning methods.

Li has assembled a multidisciplinary team for this study, including Dr. Patrick Heagerty, professor of biostatistics at the University of Washington and a cochair of the NIH Collaboratory’s Biostatistics and Study Design Core. In addition, Drs. Jeffrey Jarvik, principal investigator of the NIH Collaboratory’s LIRE NIH Collaboratory Trial, and Douglas Zatzick, principal investigator of the TSOS NIH Collaboratory Trial, serve as stakeholders of the study. The stakeholder team also includes colleagues from the NIA IMPACT Collaboratory, Drs. Thomas Travison and Monica Taljaard.
