Redes III Patient Navigator Qol Study

Overview

This proposed 5-year Redes En Acción research study involves a mixed-methods approach that occurs in two phases across two distinct and diverse HL communities. The RCT involves a 2 X 4 randomized repeated measures design with experimental condition (combined patient navigation \[PN\] over 3 months with access to LCNS PN services\[PNLCNS\] vs. a PN only condition) as the between-groups factor, and time-point (baseline/pre-randomization \[T1\]; post-PNLCNS \[about 3-months post-T1; T2\], and about 6- \[T3\] and about 12-months \[T4\] follow-up post-T2) as the within-groups factor; total follow-up is 15 months. The investigators will compare the effects of the PNLCNS and PN only conditions on QOL and treatment follow-up compliance in 300 (after attrition; n=100, Chicago and n=100, San Antonio) breast, colorectal and prostate HL cancer survivors with no evidence of metastatic disease.

Hispanic/Latinos (HL) are the largest and fastest-growing minority population in the nation. HLs generally have lower survival rates for most cancers, even after accounting for differences in age and stage distribution, which may reflect less access to timely, high-quality treatment. They also experience disproportionately higher health disparities in quality of care and access to care. The experience of cancer survivorship is often characterized by significant challenges. Despite these challenges and significant disparities observed among HLs, there is very limited knowledge of survivorship-related issues and priorities among HLs, specifically the effectiveness of using promotores/patient navigators (PN) in linking HL cancer survivors with unmet psychosocial needs to appropriate psychosocial services. The existing community-based infrastructure of the Lance Armstrong Foundation (LAF) LIVESTRONG Cancer Navigation Services (LCNS) PN program provides an excellent opportunity to evaluate its efficacy in improving QOL among HLs. This proposed 5-year Redes En Acción research study involves a mixed-methods approach that occurs in two phases across two distinct and diverse HL communities. Phase I will use a community-based participatory research (CBPR) approach to engage community-based partners that provide services to breast, colorectal and prostate HL cancer survivors. In this phase, the investigators will gather community partners for action-oriented group meetings at each site to present components and targets of the combined PN and LCNS PN program (PNLCNS). Through this CBPR approach to generate valuable community feedback, the investigators will enhance the role of the PN, develop and extend existing cooperative relationships to facilitate participant recruitment, and prepare community-based partners to disseminate and implement the PNLCNS program upon the established efficacy of the proposed randomized controlled trial (RCT) of Phase II. Phase II will test a RCT to evaluate the efficacy of a culturally tailored PNLCNS program on improving general and disease-specific quality of life (QOL) and treatment follow-up compliance among breast, colorectal and prostate HL cancer survivors. Phase II also will evaluate the extent to which intervention-associated improvements in these outcomes are mediated by targets of the PNLCNS program (e.g., communication with medical team, meeting unmet needs and improving health behaviors). The RCT involves a 2 X 4 randomized repeated measures design with experimental condition (combined patient navigation \[PN\] over 3 months with access to LCNS PN services\[PNLCNS\] vs. a PN only condition) as the between-groups factor, and time-point (baseline/pre-randomization \[T1\]; post-PNLCNS \[about 3-months post-T1; T2\], and about 6- \[T3\] and about 12-months \[T4\] follow-up post-T2) as the within-groups factor; total follow-up is 15 months. The investigators will compare the effects of the PNLCNS and PN only conditions on QOL and treatment follow-up compliance in 300 (after attrition; n=100, Chicago and n=100, San Antonio) breast, colorectal and prostate HL cancer survivors with no evidence of metastatic disease. To understand the mechanisms by which the PNLCNS significantly impacts QOL and treatment compliance outcomes, the investigators also will examine changes in unmet cancer needs, communication with the medical team, health behaviors, psychological distress, worry, coping and general self-efficacy as potential mediators of the intervention effects. The investigators will also evaluate the extent to which other factors such as preparation for consultation (i.e., medical visit) and satisfaction with cancer care are associated with our QOL and treatment follow-up compliance outcomes. Study findings will fill a significant gap in our understanding of the extent to which PN programs and existing community-based resources targeting survivors can improve the QOL of a growing number of HL cancer survivors who experience an unequal burden of unmet needs after cancer treatment. The efficacy of the proposed RCT will provide a conceptually sound and clinically relevant approach to address the needs of HL cancer survivors by integrating evidence-based practice into existing community resources and infrastructure, thus facilitating the dissemination and translation of study findings through Phase I's CBPR process.
