ACTIVE FUNDED PROJECTS

Assessing Responses to the COVID-19 Pandemic in Rural, Tribal and Non-tribal Oklahoma Communities
OSCTR Seed Grant, Nagykaldi (Co-PI)    05/01-2020 – 09/30/2020
National Institutes of Health (NIH) $30,000

This project will utilize epidemiological analyses of disease patterns coupled with rapid appraisal to examine rural tribal and nontribal Oklahoma communities’ responses to the COVID-19 pandemic. The study will provide baseline data about how rural tribal and nontribal organizations are responding to and impacted by the COVID-19 pandemic. Data collection sites will effectively become sentinel communities from which monitoring and future research efforts/interventions can be launched, including the long-term management of social distancing and other containment strategies; assessments of the capacity of rural communities and tribes to conduct contact tracing using rapid tests; utilization of telehealth/mental health; the impact of the pandemic on existing health disparities; and distribution and equity issues around eventual vaccines or treatments.

Tribally Engaged Approaches to Lung Screening (TEALS Trial)

National Cancer Institute (NCI) $96,469

Use community-engagement processes to co-design a tailored cancer care coordination system featuring nurse rural cancer care coordinators (RC3s) embedded within rural healthcare delivery systems who will help improve ONC-PCP communications. Test preliminary effectiveness of the RC3 implementation by examining processes and outcomes using a quasi-experimental design with patient- and system-level care coordination measures collected before and after implementation in at least 30 CNHSA and 30 WCWI patients. Identify factors that facilitate or hinder RC3 effectiveness.
Role: Co-Investigator

CCSG – supplemental #2 – Colorectal Cancer Screening Implementation in Partnership with Native American Communities
3P30CA225520-01S2, Mannel, Robert (PI)    05/01/2019 – 04/30/2021
National Cancer Institute (NCI) $224,082

The overall objective of the two-phased project is to increase CRC screening uptake in AIs aged 50 to 75 years who are at average risk for CRC. For this purpose, we will test the effectiveness of a comprehensive, multilevel (i.e., individual, community, and systems/ organizational), and multi-component (i.e., small media, navigation services) intervention with AI populations (on and off tribal lands) across the three states. We will focus on culturally appropriate evidence-based strategies that promote any guideline approved CRC screening (i.e., fecal immunochemical test, colonoscopy, computed tomographic colonography). During the planning phase (Year 1, eight months), we will build community-academic partnerships between I/T/U healthcare facilities, tribal entities, and university-based cancer centers; and secure tribal authorizations, IRB approvals and data sharing agreements. We will also adapt and pilot test the intervention processes and strategies. During the implementation phase (Years 2-5), we will test dissemination and implementation of multilevel and multi-component evidence-based strategies for enhancing screening. We will finalize these strategies after participatory input from our three state-specific Community Advisory Committees. Findings from this research could lead to an immediate increase in CRC screening and ultimately enhance cancer health equity by reducing the preventable CRC disease burden among AIs.
