A Web-based Peer Navigation Program for Men With Prostate Cancer

Background: Prostate cancer (PC) is a highly prevalent condition affecting 1 in 9 Canadian men. While the 5-year survival rate for PC is 93%, treatment-related side effects, such as sexual dysfunction and urinary incontinence, can significantly affect quality of life. Men with PC lack access to relevant information and emotional support, and report gaps in supportive care when dealing with these difficult issues. Previous research has shown that cancer patient navigation improves the timeliness of care and support, and reduces healthcare costs. Engaging volunteer cancer survivors as navigators is less costly, provides peer support, and benefits the navigator by improving their psychosocial health. The investigators developed True North Peer Navigation - an evidence-based peer navigation program for men with PC and a competency-based peer navigator training course. Men are matched online with a trained peer navigator who assesses needs and barriers to care, provides practical, informational, and emotional support, and empowers them to take a proactive role in their health. A pilot study showed True North Peer Navigation is highly acceptable to patients and peer navigators, and associated with improvements in quality of life, social support and patient activation to manage health. Aim: This project aims to advance knowledge on the effectiveness and implementation of a web-based peer navigation program for men after treatment for PC. Specific Objectives: 1. To determine the effect of True North Peer Navigation on patient outcomes in men with PC; and 2. To evaluate the delivery of True North Peer Navigation in terms of fidelity, cost, and the experiences of patients and peer navigators, and to identify barriers and facilitators to its implementation in oncology settings. Methods: Guided by the SPOR Patient Engagement Framework, the investigators will conduct a type-1 hybrid effectiveness-implementation study at cancer centres in Ontario, British Columbia and Nova Scotia. For objective 1, the investigators will conduct a pragmatic randomized controlled trial to evaluate the impact of True North Peer Navigation compared to an active wait list control on patient activation (primary) and needs, quality of life, anxiety, depression, fear of recurrence, social support, and access to services (secondary). One hundred and fifty-two patients (n=76 per arm) with PC will be recruited after treatment. Outcomes will be assessed at baseline (T0), 3-months (T1) and 6-months (T2). Objective 2 will involve a mixed-method process evaluation to investigate implementation fidelity, patient and navigator experiences, and cost-effectiveness of True North Peer Navigation, and to assess implementation barriers and facilitators with stakeholders informed by the Consolidated Framework for Implementation Research and the Theoretical Domains Framework. Significance: True North Peer Navigation is an innovative solution to an important service gap in the lives of men with PC. This study has the potential to generate important evidence and strategies to support the implementation of peer navigation programs to improve the health outcomes of men with PC in Canada. Note: The planned sample size described in the grant was 152 participants, considering an expected 35% dropout rate, and recruitment from three sites (PM, BC-Cancer and QEII). After the grant was awarded, we added two recruitment sites (VGH and Cape Breton Regional Hospital). As a result, the sample size was increased to 240 participants (also considering a 35% dropout rate) to address the expected increase in heterogeneity as recommended for pragmatic trials. However, recruitment at these sites was not possible due to insufficient clinical champion support. Hence, we reverted to our original planned sample size and ceased recruitment when it was reached.
