CTSI Special Populations: Pilot Projects

Pilot Funding

Current RFA 

The Special Populations Pilot Awards has been suspended until further notice. 

COVID-19 Notice

Completed submissions (LOIs, Full Applications) that are pending to the 2020-2021 Special Populations Pilot Award are on hold. Once Duke and our collaborating partners return to regular operations, new timelines and application guidelines will posted on this webpage and disseminated via regular communication channels. 

Biopsychosocial Determinants of Pain in Sickle Cell Disease

Knisely, Mitchell            

Principal Investigator: Mitchell Knisely     

Additional Investigators: Nirmish Shah and Qing Yang 

Year funded: June 2019- June 2020

Latest Updates: The CTSI Integrating Special Populations Award was able to support the initial recruitment of 48 participants. However, given the success of recruitment and ability to contain costs, Knisely was able to recruit a total of 73 participants for the CTSI study. Furthermore, Knisely was able to secure additional funding to continue sample collection. In total, biospecimens/DNA samples was collected from 94 individuals. 

Scope: Sickle cell disease (SCD) is a rare disease that negatively affects people from underrepresented minorities. Pain is a common and debilitating symptom experienced across the lifespan by people with sickle cell disease, Few effective treatments exist, resulting in opioids being a first-line treatment for this population. Specific aims for this exploratory, cross-sectional study of individuals who are 15 years and older and have SCD are to: (1) test the feasibility of blood specimen collection over a 6-month time frame; and (2) determine three pain phenotypes (i.e., no pain, episodic severe pain, persistent severe pain) based upon participant responses to a validated SCD pain measure asking the occurrence of severe pain in the last six months. Blood specimens will be collected from individuals with sickle cell disease and health controls to generate inflammatory biomarker data. Refined processes for blood collection in an underrepresented sample are already enrolled in an existing research registry.

Opioid Prescription Patterns in NC Medicaid-Insured Children

Investigators: Sudha Raman and Charlene Wong

Year funded: April 2019-March 2020 

Scope: The opioid epidemic includes children and adolescents, and there is a need to develop a local, evidence-based plan to address opioid exposures and harms among this vulnerable population. The objective of this pilot is to document the patterns of opioid prescriptions and opioid-related harms to children in North Carolina. The investigators seek to discover NC-specific patterns in a vulnerable population of low-income children, focusing on disparities by geographic region and the following age groups: infants (<2), early childhood (2-5), school age (6-11), and adolescents (12-18). This project will utilize Medicaid claims from 2013-2018 to study pediatric opioid exposure, sources of prescribed opioids, adn opioid-related harms, such as hospitalizations and emergency department visits.
