PA-20-163 - Competing Revisions to Existing NIH Grants and Cooperative Agreements (Clinical Trial Optional)

Issued by

National Heart, Lung, and Blood Institute (NHLBI)



This NOSI aims to incorporate an implementation research question into Phase II and III NHLBI clinical trials that are part of phased awards (R61/R33 and UG3/UH3). The purpose of this NOSI is to strengthen the impact of findings from the parent study and prepare for ready uptake of the clinical study results into practice and real-world applications. The parent activity code of the existing award must be an NHLBI-funded R61/R33 or UG3/UH3 phased award.


NHLBI’s Strategic Goal to Advance Translational Research seeks to advance the translation of bridging basic to clinical, clinical to practice, and population to health impact. Implementation science uses research findings to promote the uptake of clinical research into healthcare practice and health policy. Historically, implementation research occurred after clinical trials to advance the acceptance and sustainability of evidence-based practice and guidelines to populations. Implementation research may require new methods, additional funding, repeated contact of participants, an extension of data and data agreements, and other strategies to address the challenges that delay the impact of the study findings. Early in the study, the integration of implementation science is an optimal approach to improving and hasten the translation of evidence-based interventions to the intended population. Ongoing clinical trials can benefit from implementation research through the engagement of implementation science consultants, integrating data elements, including needs assessments, leading focus groups, conducting subgroup analyses, and designing sub-studies. Novel methodologies using primary and secondary data can inform subsequent implementation processes. For example, focus groups and interviewing patients, providers, and organizational leaders provide information on implementation challenges and strategies. Predictive analytics using big data (e.g., patient records, administrative data, county health reports, state-level data, etc.) inform the scale-up and sustainability of interventions from the individual to the population level. Cost analyses can determine effectiveness, benefit, and value ratios that drive healthcare care financing and policy decisions.

Innovative approaches to maximize clinical findings for timely implementation may include the use of validated effectiveness-implementation hybrid designs. State of the art, hybrid implementation designs integrate implementation data and innovation concurrently during a clinical trial to enhance effectiveness and successful implementation. There are three types of hybrid effectiveness-implementation designs: Type I) testing the effects of a clinical intervention on relevant outcomes while observing and gathering information on implementation; Type II) dual testing of clinical and implementation interventions/strategies; and Type III) testing of an implementation strategy while observing and gathering information on the clinical intervention impact on relevant outcomes.

Research Objectives

The objective of this research is to increase the use and uptake of clinical trial results by incorporating tests of implementation strategies into existing NHLBI Phased II and III clinical trials. This NOSI will support applications that propose a multidisciplinary research approach in the second phase (i.e., the R33 or UH3 phase) of the bi-phasic award. Revision supplement funds will support implementation research during the full enrollment and clinical trial execution phase (R33 or UH3 phase), not to exceed the project period of the parent award.

Applicants are encouraged to form collaborations between implementation scientists and scientists with expertise in varying disciplines (e.g., behavioral economics, informatics, data science, health systems science, shared-decision making, economics, etc.). Investigators should have a strong track record of funding in related areas, such as adherence, behavioral economics, predictive analytics, health behavior, public health, health policy, decision making, health services, comparative-effectiveness, and data analytics.

By maximizing the impact of NHLBI clinical research implementation during the clinical trial execution phase (R33 or UH3), translational research will be advanced during the intervention process, rather than after an intervention is complete.

This NOSI aims to strengthen the potential for achieving impactful implementation of NHLBI clinical research studies as they transition to the R33 or UH3 phase of award. Early integration of implementation research design into clinical trials hastens and improves the subsequent implementation process. Studies may include primary or secondary data at one or more levels of analyses (i.e., patient, provider, community, organization, state, etc.). Research designs must include proven methodologies and established implementation frameworks. Qualitative and quantitative data from needs assessments, focus groups, cost data, interviews, health surveys, electronic health records, GIS, etc. are illustrative inputs. Clinical trials may choose to blend design components of clinical effectiveness and implementation research as hybrid effectiveness-implementation design studies and are of high interest.

Potential Research Areas

Research examples that would be responsive to this NOSI include but are not limited to:

  • Use of the proposed primary and secondary outcomes of a currently funded clinical trial to develop and test a mixed-methods approach to identify the primary barriers and facilitators to adherence from a patient and community perspective.
  • Use of a validated instrument or questionnaire in a focus group setting involving patients, family members, practitioners, and other stakeholders, to determine the primary drivers of acceptability and sustained adherence to interventions.
  • Use of available resources for integration of pertinent data from electronic health records, wireless data, GIS, etc., and innovative analytical modeling, e.g., predictive analytics, advancements in the examination of implementation barriers and facilitators in medical settings, in communities, in the home, and among individuals and the families.
  • Collect and analyze cost, cost-effectiveness, and cost-benefit data of the intervention, uptake of the intervention, and implementation sustainability that inform decision making and policy decisions
  • Identification of the factors to replicate and sustain the intervention with fidelity in various contexts, including low-resource settings.
  • Improve the strategies in pharmaceutical and behavioral trials to optimize the impact of clinical trials for diverse populations and improve health equity.
  • Develop and implement strategies to address social needs and stressors. These may include the lack of access to quality food or housing and transportation needs and partnerships with community resource organizations and other entities with the expertise to address social determinants of risk that impact intervention participation, adherence, and outcomes of clinical trials.
  • Promote the adoption and maintenance of individual-level behaviors shown to improve intervention outcomes, including, but not limited to, dietary intake, physical activity, sedentary behavior, risk factor management, mental health management, and medication, and treatment adherence using innovative approaches.
  • Develop and implement strategies to overcome health care system barriers and thereby improve access to care, effectiveness of patient and provider interactions, patient health literacy, education, and treatment adherence, and strengthen overall implementation of care.
  • Use of rigorous mixed-method approaches to understand the facilitators and barriers to research participant engagement (e.g., initializing and sustaining engagement, recruitment/retention).
  • Develop and implement action plans that promote stakeholder-driven input and proposed actions to address the questions and improve the uptake of recommendations from research discoveries.
  • Use of electronic health data from participants using data science to create predictive analytical models to understand strategies that predict health outcomes, including morbidity and mortality in pragmatic trials.
  • De-implementation strategies that strengthen the adoption of evidence-based guidelines and practice targeted in the present study by decreasing or stopping low-value health care decisions.

 The following types of applications will be considered nonresponsive to this NOSI and will not be reviewed:

  • Applications in which the parent award is not an active R61/R33 or UG3/UH3 NHLBI Phase II-III clinical trial when the revision supplement application is submitted
