What is the Cardiovascular Health Awareness Program (CHAP)? 3-hour morning risk assessment and health promotion program held in local pharmacies and other locations at least 2x/month/community Essential Elements: Organized by local lead organization (LLO), Risk assessment and education of target population (>65 yrs residents of small-mid sized communities), Recording findings via fax to database, forwarding findings to participants FP and/or pharmacist
CHAP intervention Peer volunteers were trained to help participants to measure and record BP with automated device (BpTRU ) and fill out standardized CVD and stroke risk profile Community health nurse and pharmacist available to assess participants with high BP Evaluated as a cluster RCT in 2006 with 20 intervention and 19 control communities Was subsequently adopted and implemented by 22 communities in 2008-2010; Went down to 9
Theoretical Framework
Community Coalition Action Theory
Objective To identify and depict the type, extent and strength of partnership relationships within communities delivering CHAP To describe the effect of networks, partnership relationships, and other factors within CHAP communities on primary prevention of high blood pressure
Methods Cross-sectional Analysis of an on-going Cohort study Population- 9 communities operating CHAP Individual level: Participants of CHAP Partnership level: Representatives of CHAP Local Lead Organizations and Partner Organizations Community level: Review of records
Measures Independent Variables Strength of partnership Instruments to assess the Independent Variables Partnership Self- Assessment Tool (PSAT) Dependent Variables Self-reported behavior change and utilization of health resources Instruments to assess the Dependent Variables Participant Interviews Stages of Coalition Development Strength and structure of social network Coalition Effectiveness Inventory (CEI) Social Network Mapping Number and level of implementation of programs and policies related to CV Health Community Partner Interviews and Document review Community Profile Community Reports/ Environmental Scan
Methods Analysis: Descriptive Analysis for partnership and community level outcomes Ordinal Regression Association between individual, partnership, and community related factors with health behavior and use of community resources related to cardiovascular health Individual - Age, gender, marital status, number of CHAP sessions attended, self-efficacy score Partnership - type of community partners involved, number of community partners, proportion of partners with programs and policies on risk factors, % of Family Physicians and pharmacies involved with CHAP, PSAT, CEI, type of LLO Community - Rurality Index of Ontario score, Original CHAP community vs. CHAP expansion community

Discussion CEI - most communities were progressing well in the formation, implementation, and maintenance stages but not in the institutionalization stage PSAT - most communities were in the work zone levels, some were in the danger zone in Leadership Effectiveness and Administration and Management Participants attending CHAP reported improvements in health behavior and use of community health resources after attending CHAP sessions
Discussion Some individual, partnership, and community related factors affected CHAP participants behavior change and use of community resources
Implications and On-going actions Strength of partnerships (CEI and Proportion of pharmacies involved) affected CV health behaviors & use or resources in communities implementing the CHAP We have presented some of the results to the communities We are currently measuring all information for T2 of our Cohort study
Limitations Individual health behavior change and use of community resources are based on selfreports Only 9 communities are included so partnership and community level outcomes can only be analyzed descriptively
Thank You. Questions

Instrument: Methods Coalition Effectiveness Inventory (CEI) developed by Butterfoss et al [2004] to measure a coalition s development as they progress through 4 stages: formation, implementation, maintenance and institutionalization Partnership Self-assessment Tool (PSAT) developed by Lasker et al [2001] to measure strengths and weaknesses in areas that are known to be related to synergy (leadership, efficiency, administration and management, and sufficiency of resources)
Instrument: Social Network Map Methods Measures connectivity through interactions between partners in a collaborative, such as the amount and quality of interactions and how these relationships might change over time [Varda 2008]
