Project overview

In 2017, the Policy, Location and Access in Community Environments (PLACE) Research Lab, School of Public Health, University of Alberta and Alberta Health Services (AHS) - Alberta Cancer Prevention Legacy Fund (ACPLF) collaborated to develop strategies to support cancer and chronic disease prevention in communities and workplaces. The goal of this project was to develop a set of evidence-based and contextually relevant strategies across seven focus areas (alcohol misuse, cancer screening, healthy eating, mental wellness, physical activity, tobacco use and ultraviolet exposure) that would help communities and workplaces foster supportive physical and social environments to reduce the risk of developing cancer and chronic disease. The strategies for these seven focus areas were developed in three phases described below.

Phase 1: Evidence search

The goal of Phase 1 was to gather high quality, current evidence regarding environmental and policy change strategies that support community and workplace action on cancer and chronic disease in the seven focus areas.

Evidence search method

Guidelines developed by the National Collaborating Centre for Methods and Tools (NCCMT) to support public health evidence searches were used.1 Figure 1 provides an overview of the six levels of evidence recommended by the NCCMT regarding purpose, level definition and areas to search within each level.

The NCCMT recommends that evidence searches begin at the top of the pyramid (i.e., focus on the highest quality sources) and then work down through the pyramid to find additional evidence as necessary.1 Within public health, there is no evidence at the ‘systems’ level,1 so efforts were focused on the subsequent ‘summaries’ and ‘synopses of syntheses’ levels.

The search examined 20 databases, websites and search engines for ‘summaries’ and ‘synopses of syntheses’ related to the seven focus areas within community and workplace settings.

The search strategy focused across a variety of sources that spanned specific keyword searches through to database topic area searches (Table 1). Sources of evidence were limited to English language documents. The search emphasized evidence published during the past three years (i.e., 2014-2017) based on NCCMT recommendations for evidence-informed decision-making in public health. Evidence prior to 2014 was included and categorized separately (i.e., to capture established evidence that may not have changed in the intervening period) during the current phase of the project. Although the search was internationally inclusive, the documents revealed were primarily from Canada, the United States, the United Kingdom and Australia.

SEARCH STRATEGY SOURCE OF EVIDENCE
Hand-search of all guidelines available on website Canadian Task Force on Preventive Health Care; CDC -- The 6|18 Initiative; Partnerships to Improve Community Health; Workplace Health Promotion; Cochrane Collaboration, Public Health

General search using terms specific to each of the focus areas

Cancer Care Ontario - Guidelines and Advice; CPAC Prevention Policy Directory; US Preventive Services Recommendations; National Guideline Clearinghouse; National Institute for Health and Care Excellence
Specific search using terms specific to each of the focus areas, plus some or all the following terms: (evidence OR evidence-informed OR evidence-based OR best practice OR guideline OR strategy OR policy OR intervention) AND (community OR workplace OR school OR work) Trip Database; Google Search Engine
Selected pre-determined topic areas listed in drop-down menus or toggle buttons, one-by-one (topics were selected if they related to one or all the focus areas) Health Evidence.ca; World Health Organization; Research-tested Intervention Programs; Healthy People 2020; Guide to Community Preventive Services; The Campbell Collaboration; Canadian Best Practices Portal; EPPI Centre

Information extracted from each document included the year of publication (and year of any updates), title, URL, description of recommendations, search date and search number. The Appraisal of Guidelines for Research and Evaluation (AGREE) II tool (www.agreetrust.org/agree-ii/) was used to critically appraise the ‘summaries’ and the Critical Appraisal Skills Programme (CASP) tool (www.casp-uk.net/casp-tools-checklists) was used to assess ‘synopses of syntheses’. If the quality of the document was deemed low according to these tools, it was excluded.

Evidence documents reported on single or multiple strategies for each of the focus areas in the community and/or workplace setting. Relevant strategies were extracted from each document.

Upon review of the evidence, PLACE Research Lab and ACPLF identified a number of gaps in the evidence. The gaps were a symptom of the purposeful high level search strategy that was utilized. To addresses these gaps, ACPLF identified two topics for immediate rapid review: workplace mental health and community gardens. It is important to note that the workplace mental health rapid review included evidence from a systematic review level and community garden rapid review included evidence from primary research studies. Within the strategies outlined throughout the website, evidence derived from the rapid reviews are identified with a double asterisks (**).

Phase 2: Strategy development

A four-step approach (Figure 2) was used to develop a subset of strategies based on the evidence search results gathered in Phase 1.

Overview of strategy development steps

In Step 1, PLACE Research Lab research assistants summarized evidence collected during the Phase 1 evidence search into draft strategies for each focus area. Research assistants reviewed guideline development protocols to determine an approach to convert evidence into recommendations (Appendix A). The research assistants used elements of the protocols to inform the process by first reading through the entire evidence report and then summarizing evidence into key strategies that captured the breadth of the evidence identified.

In Step 2, a PLACE Research Lab associate reviewed the draft strategies. In this step, the primary evidence identified was also reviewed to ensure accuracy in strategy development.

In Step 3, the PLACE Research Lab team worked with an Alberta Policy Coalition for Chronic Disease Prevention (APCCP) policy analyst to conduct a final internal review. The APCCP is a provincial non-profit organization that represents a broad range of practitioners, policy-makers, researchers and community organizations who coordinate efforts, generate evidence and advocate for policy change to reduce chronic disease in Alberta (http://abpolicycoalitionforprevention.ca). Given this mandate, the APCCP policy analyst was an ideal resource to support strategy review. The APCCP policy analyst and PLACE Research Lab research associate worked together to refine strategies and ensure they were relevant to community and workplace contexts, while retaining a clear link to the original evidence.

In Step 4, APCCP member organizations (Appendix B), the AHS focus area teams (via ACPLF) and ACPLF community partners conducted a practice and policy review to ensure that strategies were applicable within the Alberta context.

Phase 3: Final strategy development

Following the strategy review completed by APCCP member organizations, AHS focus area teams and ACPLF, all suggested feedback and revisions were carefully reviewed by the PLACE Research Lab team and incorporated into final strategies for each focus area.
