Brief Summary:
Addictions do not occur in isolation. Tackling addictions requires addressing social determinants such as isolation, homelessness, marginalization, and unemployment. Research on individuals living with or at risk for HIV/AIDS highlights that unemployment correlates with higher levels of depression, anxiety, and social isolation compared to employment. In Ottawa, the PROMPT project engaged homeless or at-risk populations, including people who use drugs and those living with or at risk for HIV/AIDS or Hepatitis C using the Bridge ModelTM, a pragmatic community-based participatory action research approach operationalized through earlier projects at the Bridge Engagement Center in Ottawa, Canada. The PROMPT project demonstrated that implementing multi-component, complex interventions is both feasible and effective, achieving broader socio-economic outcomes beyond reduction and quitting tobacco and poly-substance use. However, PROMPT participants identified a lack of social and recovery capital -family and social connections, opportunities for volunteering and jobs- as a major barrier to recovery. To address this, we conducted a six-month feasibility pilot study with 20 PROMPT participants. By its conclusion, 15 participants were engaged in small paid or volunteer roles, including educational opportunities, fostering both social integration and recovery. Insights from this pilot study informed the design of a larger community-based multi-site pragmatic randomized trial (RCT) to further evaluate the effectiveness of the Bridge ModelTM, the Healthy People Initiative (HPI) project. The Healthy People Initiative (HPI) is a community-based, participatory, pragmatic parallel-arm multi-site with a cross-over design, recruiting 250 participants (16+) at risk of homelessness or low socioeconomic status in Ottawa and Toronto, Canada.
Detailed Description:
Title of Trial: A Healthy People Initiative (HPI) - Community-Based Participatory Action Pragmatic Parallel Arm Multi-Site Randomized Controlled Trial using The Bridge ModelTM in Systemically Disadvantaged Populations: HPI Trial Protocol
Short Title of Trial: HPI Trial
Principal Investigator: Smita Pakhalé
Trial Sites: Ottawa (The Bridge Engagement Centre) \& Toronto (Parkdale Activity Recreation Centre)
Primary outcome: The Healthy People Initiative (HPI) randomized controlled trial (RCT) builds on the pilot study to evaluate changes in participants' self-reported quality of life (QoL) as the primary outcome while implementing the Bridge Model™ approach to address tobacco management.
Secondary outcomes: The secondary objective is to quantify reductions in tobacco use and quitting tobacco use altogether, with quit rates validated biochemically, and changes in self-efficacy.
Tertiary outcomes: These include evaluating process-related metrics such as participant enrolment rates, consent rates, and adherence to protocol; estimating implementation costs to guide future cost-effectiveness analyses; and assessing additional patient-reported outcomes such as self-efficacy, participation in education or employment, and reductions in polysubstance use. Additionally, a cost-utility analysis from a health system perspective will assess the economic impact of the 52-week intervention by measuring total costs and healthcare utilization, linking trial data to administrative health records. We aim to provide robust evidence to support the utility of the Bridge ModelTM in addressing health and social inequities through community-driven, peer-led interventions that integrate social determinants with individual health outcomes.
Primary Objective: To assess the feasibility of a randomized controlled trial investigating access to improvements in 'social capital' in the low income population in Ottawa and Toronto.
Study Design \& Population: The HPI study is a crossover, community-based, multi-site pragmatic RCT (1:1 allocation ratio) in Ottawa and Toronto. It uses a 12-month follow-up to evaluate short- and long-term effects of the intervention on health, social, and economic outcomes. Data sources include self-reports, biochemical validation, and administrative health records
Sample Size: 250
Trial Arms: The HPI RCT has two arms: usual care and intervention (Figure 1). The intervention arm employs the Bridge ModelTM, offering life-skills workshops, social integration, peer guidance, system navigation (e.g., housing), and APN (Advanced Practice Nurse) or NP (Nurse Practitioner) counselling, including primary care, preventive services, and referrals. Both arms receive monthly follow-ups from peers and APN/NP. Usual care includes resource information and counselling, with an option to switch to the intervention arm after six months. All participants receive nicotine replacement therapy (NRT) for 12 months as needed.
Trial Duration: 12 months Follow-up Duration: 12 months
