Theories of the policy process in health promotion research: a review

The Ottawa Charter laid the ground work for a new research and practice agenda by urging health promoters to advocate for healthy public policies. After more than 20 years, it is now time to reflect on the state of policy research in health promotion and to examine how rigorously theories are applied. The review of the literature was
conducted on 11 peer-reviewed journals. The journals were selected for their solid track record in publishing health promotion articles and by using a set of predefined
inclusion and exclusion criteria. The articles, published between January 1986 and June 2006, were searched using Medline and CINAHL databases. The selected papers feature search terms related to ‘politics’, ‘policy’, ‘advocacy’ and ‘coalition’. We examined the theoretical grounding of each paper and whether it focuses on policy content (e.g. nature, impact, evolution of the policy), policy processes (e.g. advocacy capacity building and strategies) or theoretical/methodological issues in policy analysis. This review demonstrates that policy research in health promotion is still largely an a theoretical enterprise. Out of the 119 articles that were found eligible, 39 did apply to some degree a theoretical framework, of which 21 referred to a theoretical framework from political science. We conclude that the field has yet to acknowledge critical concepts that would help to shed light on the policy process, and that validated rigorous theoretical frameworks to inform research and practice are hardly applied. Recommendations are formulated to improve policy research in health promotion.

Dietary patterns, assessed from a weighed food record, and survival among elderly participants from the United Kingdom

Background/Objectives: There is variability in the association between dietary intake and health outcomes across different countries, especially among the elderly. We used the gold standard dietary assessment method, a weighed food record, to examine the association between dietary pattern and mortality in a representative sample of community dwelling participants from Great Britain aged 65 years and older.

Subjects/Methods: Dietary intake was recorded at baseline in 1017 elderly participants (520 men, 497 women, mean age 76.3±7.4 years). Exploratory factor analysis was performed to examine dietary patterns and participants were followed up over an average of 9.2 years for mortality.

Results: The factor analysis revealed four interpretable principal components accounting for approximately 9.8% of the total variance, with similar patterns across sex. A ‘Mediterranean-style’ dietary pattern explained the greatest proportion of the variance (3.7%), followed by ‘health-aware’ (2.2%), ‘traditional’ (2.0%) and ‘sweet and fat’ (1.9%) factors. There were a total of 683 deaths through follow-up. After adjustment for potential confounders, only the Mediterranean-style dietary pattern remained associated with mortality (highest vs lowest tertile; hazard ratio¼0.82, 95% CI, 0.68–1.00). The benefits of the Mediterranean-style diet were only observed among women (hazard ratio¼0.71, 95% CI 0.52–0.96) although in men the traditional diet was a risk factor for mortality (hazard ratio¼1.30, 95% CI 1.00–1.71).

Conclusions: Using a gold standard approach, our results confirm previous evidence that dietary patterns are important in longevity among the elderly.

Validation of de-identified record linkage to ascertain hospital admissions in a cohort study

Background Cohort studies can provide valuable evidence of cause and effect relationships but are subject to loss of participants over time, limiting the validity of findings. Computerised record linkage offers a passive and ongoing method of obtaining health outcomes from existing routinely collected data sources. However, the quality of record linkage is reliant upon the availability and accuracy of common identifying variables. We sought to develop and validate a method for linking a cohort study to a state-wide hospital admissions dataset with limited availability of unique identifying variables.

Methods A sample of 2000 participants from a cohort study (n = 41 514) was linked to a state-wide hospitalisations dataset in Victoria, Australia using the national health insurance (Medicare) number and demographic data as identifying variables. Availability of the health insurance number was limited in both datasets; therefore linkage was undertaken both with and without use of this number and agreement tested between both algorithms. Sensitivity was calculated for a sub-sample of 101 participants with a hospital admission confirmed by medical record review.

Results Of the 2000 study participants, 85% were found to have a record in the hospitalisations dataset when the national health insurance number and sex were used as linkage variables and 92% when demographic details only were used. When agreement between the two methods was tested the disagreement fraction was 9%, mainly due to "false positive" links when demographic details only were used. A final algorithm that used multiple combinations of identifying variables resulted in a match proportion of 87%. Sensitivity of this final linkage was 95%.

Conclusions High quality record linkage of cohort data with a hospitalisations dataset that has limited identifiers can be achieved using combinations of a national health insurance number and demographic data as identifying variables.

Implementing scanned medical record systems in Australia : a structured case study on envisioned changes to elective admissions process in a Victorian hospital

In recent years, influenced by the pervasive power of technology, standards and mandates, Australian hospitals have begun exploring digital forms of keeping this record. The main rationale is the ease of accessing different data sources at the same time by varied staff members. The initial step in this transition was implementation of scanned medical record systems, which converts the paper based records to digitised form, which required process flow redesign and changes to existing modes of work. For maximising the benefits of scanning implementation and to better prepare for the changes, Austin Hospital in the State of Victoria commissioned this research focused on elective admissions area. This structured case study redesigned existing processes that constituted the flow of external patient forms and recommended a set of best practices at the same time highlighting the significance of user participation in maximising the potential benefits anticipated. In the absence of published academic studies focused on Victorian hospitals, this study has become a conduit for other departments in the hospital as well as other hospitals in the incursion.

Inclusion in participatory research: what were the whitefellas doing in an Aboriginal health project?

Health research in indigenous communities, like many interactions between such communities and white-dominated institutions, has a chequered history leading to a three-fold decrement: suspicion and resistance to research that is seen as coming from outside of the community; a shortage of research generators and leaders within the community; and cumulative gaps in the research evidence base, both in terms of coverage of topics and in terms of meeting the priorities of the community.

Additionally, these decrements have been mistakenly located as problems being caused from within the community, rather than recognising that these are outcomes of wider contextual, historical and institutional factors and failings. Good research, as culturally appropriate, inclusive of community voices and meeting the needs and priorities of the community, is necessary in an increasingly evidence-based-practice culture within policy and health settings. Culturally safe research with and for indigenous communities has the potential to be empowering, and to bring community voices, views and experiences into the influential realm of'evidence.

This process of developing safe, appropriate and inclusive research is not straightforward: the decrements are recursive, with a shortage of connections between the community, its priorities and research. However, as the Healing Stories project that we discuss here has shown, it is possible to develop culturally safe participatory research by working with Elders from within the community and with leaders from within white institutions, in a spirit of reconciliation. The methods and findings of Healing Stories have been reported elsewhere, with an emphasis on the voices from the community; this chapter explores some of the 'behind the scenes' processes, from the perspective of the white researchers working from within white- dominated institutions.

After briefly describing the Healing Stories project, this chapter reflects on three parts of the participatory research process: getting started, leading together, and working together. The first of these considers laying the foundations for participatory research, working with Elders and leaders, and planning for inclusion, examining participatory research as a recognisable research design, with potential for rigour, cultural safety and inclusion. The second explores developing participatory methods, working with communities, and opportunities and choices for inclusion. The third examines the process of being participatory, working together and engaging in inclusion across the long-term commitment to the project.
