E-mail: toni.delany@flinders.edu.au Summary Health in All Policies (HiAP) is a policy development approach that facilitates intersectoral responses to addressing the social determinants of health and health equity whilst, at the same time, contributing to policy priorities across the various sectors of government. Given that different models of HiAP have been implemented in at least 16 countries, there is increasing interest in how its effectiveness can be optimized. Much of the existing literature on HiAP remains descriptive, however, and lacks critical, empirically informed analyses of the elements that support implementation. Furthermore, literature on HiAP, and intersectoral action more generally, provides little detail on the practical workings of policy collaborations. This paper contributes empirical findings from a multi-method study of HiAP implementation in South Australia (SA) between 2007 and 2013. It considers the views of public servants and presents analysis of elements that have supported, and impeded, implementation of HiAP in SA. We found that HiAP has been implemented in SA using a combination of interrelated elements. The operation of these elements has provided a strong foundation, which suggests the potential for HiAP to extend beyond being an isolated strategy, to form a more integrated and systemic mechanism of policy-making. We conclude with learnings from the SA experience of HiAP implementation to inform the ongoing development and implementation of HiAP in SA and internationally. Key words: Health in All Policies, health policy, equity, social determinants, intersectoral action INTRODUCTION Health in all Policies (HiAP) facilitates intersectoral relationships and policy development to address health and equity issues while also contributing to other sectors’ policy goals. The intersectoral focus recognizes that health is influenced by a wide range of factors such as housing, employment and transport (Baum, 2008). HiAP sees that promoting health will also assist in stimulating economic productivity and reduce the cost of health care (Government of South Australia, 2011b). HiAP has now been implemented in various forms in at least 16 countries © The Author 2015. Published by Oxford University Press. All rights reserved. For Permissions, please email: [email protected] Health in All Policies in South Australia (Shankardass et al., 2011). As such, there is increasing interest in how the effectiveness of the approach can be optimized (Kickbusch, 2008; World Health Organisation and Ministry of Social Affairs and Health, 2013). This interest has stimulated a growing body of international literature, which examines the enablers and barriers to HiAP work. Much of the literature consists of commentaries or practice-based reflections, which draw on the experiences of staff from organizations within the health sector. The literature remains largely descriptive and lacks critical, empirically informed analyses of the elements that support HiAP implementation (Shankardass et al., 2012; Chircop et al., 2015; Shankardass et al., 2014). Furthermore, literature on HiAP, and intersectoral action more generally, provides little detail on the practical workings of policy collaborations (Bryson et al., 2006; Chircop et al., 2015). Despite these limitations, the existing literature provides insight into factors that may facilitate or impede HiAP implementation, which can inform analysis of emerging empirical data within the field, particularly on the topics of trust, stakeholder involvement, recognition of context and government funding. Trust is identified as an essential element of effective intersectoral collaborations (Van Eyk and Baum, 2002; Axelsson and Axelsson, 2006; van der Heiden, 2010; Ogden et al., 2013; Rudolph et al., 2013a; World Health Organisation, 2013). Maintaining trust within partnerships through fulfilling commitments and maintaining open communication also assists in developing credibility, which is another key facilitator of effective intersectoral work (van der Heiden, 2010; Leppo et al., 2013; Leppo and Tangcharoensathien, 2013). Several authors (Krech, 2010; Ollila, 2011; Rudolph, 2013; Rudolph et al., 2013a) argue that to build and maintain trust during the implementation of HiAP it is important for the health sector to pursue transparent agendas and share credit with collaborators. Discussions within the literature also indicate that it is important to involve collaborating sectors at each stage of applying the HiAP approach to facilitate successful partnerships (World Health Organisation, 2011; Bostic et al., 2012; Steenbakkers et al., 2012; Leppo et al., 2013; Leppo and Tangcharoensathien, 2013). Rudolph et al. (Rudolph et al., 2013a) recommend explicit discussions to develop mutual goals at the beginning of the HiAP process, ensuring all parties are able to identify shared benefits. Understanding the particular institutional, policy and political contexts that operate within the sectors that collaborate under a HiAP approach is also imperative to maintaining productive partnerships and relevant outputs. Freiler et al. (Freiler et al., 2013) and Hendriks et al. (Hendriks et al., 2013) suggest that this necessitates 889 an approach where the focus and targets are framed to suit the context within which the collaborating sector/s operates (Freiler et al. 2013; Hendriks et al. 2013). Such an approach also discourages ‘health imperialism’ where problems and the necessary actions are defined from the viewpoint of the health sector only (Nutbeam, 1994; Howard and Gunther, 2012). Political context has an impact on the HiAP approach. In particular, short-term investment of resources can prevent adequate funding for sustained intersectoral work (Bacigalupe et al., 2010; Ollila, 2011; McDaid, 2013; Rudolph et al., 2013b). Bacigalupe et al. (Bacigalupe et al., 2010) refers to the concept of ‘policy myopia’, where politicians divert resources into policies that yield short-term results, which will be realized while they are still in office. This is due to the short-term nature of electoral terms, and the emphasis placed on maintaining political power, which several authors (Lin, 2010; Greaves and Bialystok, 2011; Ollila, 2011) assert are not conducive to supporting sustained intersectoral action that is intended to stimulate long-term benefits. Our findings build upon the literature in several ways. The research contributes empirical and nuanced evidence produced by capturing diverse public servant perspectives across sectors. Within the paper, the complexities associated with establishing and satisfying shared intersectoral goals are examined. The impact and politics of resourcing are also considered in further depth through examination of the views of those who participate in HiAP work in the South Australian (SA) context. The paper describes the interrelatedness of the elements that have underpinned implementation of the HiAP approach in the SA context. Background: the SA HiAP approach HiAP was trialled and developed from 2007 in SA by the Health Department and the central office of Government, the Department of the Premier and Cabinet (DP&C), in response to recommendations made by Adelaide Thinker in Residence Ilona Kickbusch (Government of South Australia, 2011b). As a cross government process it was formally endorsed by State Cabinet in 2008. A dedicated HiAP Unit was formed within the Health Department to facilitate implementation. Between 2007 and 2013 this Unit grew from having one staff member to six, and the staff worked with 13 different departments/ agencies during that time in various sectors, including the environment, planning and transport sectors (Delany et al., 2014a). In 2010, the Shadow Health Minister supported the widespread application of the HiAP approach in many policy areas, implying bipartisan support (South Australian House of Assembly, 2010). T. Delany et al. 890 HiAP work is linked to the agenda of the SA Government, as expressed in the South Australian Strategic Plan (SASP) (Government of South Australia, 2010a) and the Seven Strategic Priorities of Cabinet (Government of South Australia, 2011a). DP&C oversees implementation of the HiAP approach, and has signed a memorandum of understanding with the Health Department for joint governance of HiAP (Government of South Australia, 2010b; Figure 1). Other defining features of the SA HiAP approach between 2007 and 2013 included working on the basis of a co-operation strategy (Ollila, 2011) (often referred to as co-benefits) and use of a Health Lens Analysis (HLA) process. The HLA process provided a mechanism for examining the connections between policy and health in a systematic and collaborative manner, which often resulted in evidence-based recommendations to guide policy strategy (Lawless et al., 2012) (refer to Government of South Australia 2011b; Baum et al., 2014; Delany et al., 2014b for further information). HLA projects were jointly funded by resources from the Health Department and the collaborating departments/agencies. Figure 1 illustrates the governance structure and the stages of the HLA process. The outputs that have been produced so far have varied depending on the particular foci of collaborations but they have included literature reviews, reports, commissioned research to examine stakeholder perceptions and an atlas of health status in particular communities. These outputs have already had some impact on policy. For example, the South Australian Numeracy and Literacy Strategy 2013 drew directly on the collaboration between Education and Health on a HLA project that investigated strategies for engaging parents in their children’s literacy development (Delany et al., 2014a). METHODS The data presented in this paper were collected during the first 2 years of a 5 year research project that is designed to address the question ‘Does a Health in All Policies approach improve health equity and wellbeing?’ The research is focussed on the South Australian HiAP approach and is underpinned by a critical action research framework (Baum et al., 2014). The methods applied include in-depth interviews, workshops and a survey [For further information about the research refer to (http://www.flinders.edu.au/medicine/sites/ southgate/research/health-equity-and-policy/hiap.cfm)]. All data collection activities received prior approval from the (Flinders University) Ethics Committee and the SA Health Ethics Committee. The research is funded by the Australian National Health and Medical Research Council. Fig. 1: SA HiAP Model 2007–2013 (Government of South Australia, 2011b). Health in All Policies in South Australia 891 Data collection and analyses Interviews Fifty-two individuals participated in a total of 70 semistructured, in-depth interviews between January 2013 and February 2014. These interviews involved public servants, four politicians and political staff members and three academics who have had contact with the HiAP approach since 2007. This paper draws on a sub-set of the interviews to examine the views of public servants working across various sectors of the SA Government about the factors that have facilitated and impeded HiAP in SA. Forty-five public servants were interviewed (Table 1); 15 of these people work within the Health sector and the remaining 30 work in the 13 Departments and Agencies that have collaborated with Health on HiAP work. A total of 62 interviews were undertaken, with 12 public servants interviewed more than once (between two and four times) given their roles in several HiAP projects, or the need to capture information about developments over time. Interviews were undertaken by six experienced academic interviewers. Questioning was guided by a pre-prepared interview schedule, as well by the flow of participants’ own narratives. The interviews were recorded and transcribed verbatim. The interviews averaged 55 min and ranged from 15 min to 1 h 35 min. Workshops Two workshops were undertaken during mid-2013 to inform development of a theory-based programme logic model designed to assist evaluation of the SA HiAP approach. The first workshop involved nine public servants from five different Agencies that had collaborated with Health as part of HiAP HLA projects. The second workshop was attended by 16 public servants from the SA Health Department. Both workshops lasted 4.25 h. Participants were asked about the factors that led to HiAP being introduced in SA, the assumptions, activities and processes that underpin HiAP implementation and the short- and longer-term goals of HiAP work. There were also frequent discussions about the context Table 1: Positions of interviewees Positions Number of interviewees Chief executives or agency heads Deputy chief executives Other public servants ( policy officer to director level, still working or retired) Total 6 2 37 45 surrounding HiAP. The workshops were audio recorded and transcribed verbatim. Analysis of interview and workshop transcripts Data collection and analysis proceeded simultaneously. The research team conducted a collaborative, thematic analysis of the interview and workshop transcripts using the qualitative analysis software NVivo 10. Following the initial round of open coding, which involved one member of the team (T.D.) reading the transcripts to identify the central themes as well as collaborative coding sessions involving several other team members, selective coding (Ezzy, 2002) was applied to examine participants’ discussion of factors that facilitated and impeded HiAP implementation in more depth. Concept mapping was then undertaken to explore the relationships between the themes and to move from description to explanation through further team discussion and consultation of the relevant literature. Survey During May and June 2013 public servants from many SA Government Departments were invited to complete an online survey. The survey included 50 questions (13 of which were open ended) to elicit information about respondents’ awareness of the HiAP approach, experiences of collaborating with HiAP work, perceptions about barriers and enablers to undertaking HiAP work, perceived outcomes of HiAP work as well as respondents’ reflections on how the social determinants of health and equity relate to the core business of their departments. Three hundred and seventythree people were eligible for participation in the survey, based on having had some contact with the HiAP approach between 2007 and 2013 and still working within the Government at May 2013. One hundred and sixtyeight public servants responded to the survey and 128 answered all questions. Most respondents were from the Health sector (40.7%); with 11.7% from DP&C, 9.8% from the planning sector, 7.4% from communities and social inclusion and 6.2% from the education sector making up the majority of the remaining participants. Forty per cent of all respondents had been working within the SA government for 20 years or more, and 29% had been working in the Government for between 10 and 20 years. The participants had a range of roles in working with HiAP, such as facilitating links between HiAP staff and their own department/agency (39.9%), working on a HLA project (27.7%) and supporting the development of the HiAP approach or Unit in SA (27%). Length of involvement with HiAP was spread relatively evenly between 1 and 5 years among respondents. Numerical 892 data collected during the survey were analysed using SPSS software to create tables showing the percentage of respondents who selected particular answers to each question. Cross tabs were also used to compare relationships between responses to selected questions. Data from the open ended questions was analysed thematically using NVivo 10. Selected results relevant to the focus of this paper are presented. FINDINGS This section presents key themes emerging from the analysis to explain the elements that have supported, and impeded, implementation of HiAP in SA. The supportive elements of resourcing, trust, credibility and alignment of policy priorities are discussed first. This is followed by examination of impeding factors, including lack of support from some members of the policy community, resource constraints and timeliness. Factors that have supported implementation in the South Australian context The provision of a resourced, centrally mandated unit. Resources. Participants identified multiple benefits associated with the provision of the dedicated HiAP Unit. It provided a core group of staff who were resourced to apply the HiAP approach. Partners on HiAP projects viewed this dedicated resource as essential in progressing HiAP work: I don’t think any of this would have happened unless there was a dedicated Unit and the resources to go with it . . . we’ve thrown in a little bit of money that was available at the end of the financial year but it could quite as easily have gone to something else. It was the human resources within the Unit that actually made it happen. (Workshop 1, senior public servant from sector other than Health) Another benefit was that the dedicated Unit employed Health staff with a range of skills, both in maintaining collaborations and in identifying the potential health impacts of proposed plans. These skills were identified as instrumental to project success, and often as complementary to the diverse skill sets possessed by staff from collaborating sectors. The majority of survey respondents either agreed (45.1%) or strongly agreed (12.3%) that collaboration with HiAP gives their department access to people with different skills. This emerged as a key facilitator, which has not been previously identified in literature on HiAP. Governance and mandate. The involvement of DP&C in overseeing the HiAP approach was widely seen to support T. Delany et al. the entry of HiAP staff into departments across the Government. It positioned HiAP as offering a ‘pool of resources that can be accessed across Government’ (Workshop 2, public servant from Health). Furthermore, Chief Executives from all Government departments sit on committees that are facilitated by DP&C. These committees have been established to drive implementation of work across the Government under key policy frameworks, such as the SA Strategic Plan and the Seven Strategic Priorities of Cabinet. Several interview and workshop participants indicated that DP&C’s involvement in overseeing HiAP, as well as HiAP’s alignment with these policy frameworks, increases the potential for the HiAP approach to be discussed during committee meetings, allowing collaboration opportunities to be identified and explored. The joint governance structure of HiAP requires that project proposals and final reports be signed off by senior executives in Health and the collaborating departments, and, often, by DP&C. This increased opportunities for the exposure of key achievements at the senior level, thereby motivating partners’ collaboration: one of the things in favour of participating in the HiAP project was the fact that it was reporting up to a body that I thought would have some influence for change. (Workshop 1, public servant from sector other than Health) Appeal of the unit. Participants indicated that they were motivated to engage with the HiAP Unit because it was easier to work with than other parts of the Health Department. I’m not seeing a shift in the way that the Health Department operates in terms of its relationship with other parts of Government but the HiAP Unit does. So in a sense it’s their positive interaction with us that really is the – well, I’m not sure whether we’d call it a success yet but I guess the ongoing goodwill that’s going on is because of that Unit. (Workshop 1, senior public servant from sector other than Health) HiAP staff recognized the potential benefits of this and purposefully framed their approach in a way that emphasized their connection to DP&C to facilitate their entry into other departments. we don’t talk about ourselves as being Health Department people . . . so if we’re going to knock on a new door we’re coming under the auspices of Department of the Premier and Cabinet, because they’ve authorised us to act. (Workshop 2, public servant from Health) Health in All Policies in South Australia Establishing and maintaining trust and credibility Discussions of trust are woven throughout the data. Five interviewees from departments other than Health admitted that they were initially sceptical of collaborating with Health, because they were uncertain of the likely benefits or the extent to which true collaboration, involving shared agenda setting and fair work distribution, would be realized. Six participants from Health reported that they responded to collaborators’ initial uncertainty, as well as their own unfamiliarity with other departments, by making efforts to build a relationship and learn about each others’ work prior to planning the projects. This built the acceptability (Shankardass et al. 2014) of the HiAP approach and developed relationships that would facilitate the subsequent work. I think after a while the trust built and [we realised] from a cost benefit point of view for us the returns were good for what we had to put in. (Workshop 1, senior public servant from sector other than Health) The interviews also revealed, however, that there is potential for trust and credibility to be lost within HiAP collaborations. Particular actions that were identified as compromising this included collaborators failing to honour commitments, not establishing or maintaining clear work plans and neglecting to uphold agreed processes of group engagement and decision-making within working groups. Aligning HiAP with core business and strategic priorities Participants frequently emphasized the importance of HLA projects, and their anticipated outcomes, being aligned with the core business agendas of all departments involved, as well as the Governments’ broader strategic directions, policy and legislation, such as the SA Strategic Plan, Cabinet Priorities and the SA Public Health Act. Achieving such alignment was particularly important within the political climate at the time of data collection where there was high pressure to achieve savings and to ensure that all expenditure was closely aligned with current priorities. The Public Health Act and the public health planning process present opportunities to us of embedding HiAP type processes as part of everyday business and building the capacity of people to work in a partnership type way with others because, quite frankly, we’re not going to have the money anymore to achieve things through, you know, buying the work of others if you like. (Interview, senior public servant from Health) Apart from justifying funding, aligning the focus of HiAP work with the goals of collaborating departments and 893 with the overall strategic objectives of the Government also motivated intersectoral engagement. Well, generally I guess common purpose facilitates it . . . so there are obviously common agendas so you come together over that. (Interview, public servant from a sector other than Health) Similar ideas were reflected in the survey data in response to open ended questions about what factors encourage departments to collaborate with Health and what worked well during the collaborations: Alignment of strategic objectives and the commonality of social factors that influence both education and health outcomes.’ (2013 survey, senior public servant from sector other than Health) Working with HiAP provided an opportunity to align our work to the Seven Strategic Priorities of Cabinet (2013 survey, public servant from sector other than Health). Within the survey, workshop and interview data aligning HiAP work with mutual goals and developing mutual understandings about the work were identified as key activities, and skills, of HiAP staff. we had interactions with a different unit [within Health] and we were getting nowhere because their headsets were different. There wasn’t an empathetic positioning from [that unit within] Health about what our portfolios, drivers and concerns were so one couldn’t actually progress . . . what I think the Health in All Policies team did was ‘let’s try and get into the heads of people that work in a different policy space and work out from that, see the areas of commonality’. (Workshop 1, senior public servant from sector other than Health) One of the ways HiAP staff have facilitated the development of mutual understanding and goals is by avoiding the use of sector-specific language, while examining how particular terms, such as equity and health, are defined and understood in partnering departments. . . . the challenge was really conceptualising our work in the language of the other institution and vice versa . . . we had to get our heads around different language and establish common ground about the use of language, but also establish a stronger sense of understanding of each other’s work and institutions and how they look, I think that was a challenge for me . . . (Interview, public servant from Health) Threats to HiAP within the South Australian context Lack of support from some members of senior management Despite the strong support provided by DP&C, as well as the support garnered among policy staff, some senior managers were less supportive of collaborating with HiAP. Interview participants from four different Departments reported unsupportive senior managers. 894 This issue was also identified during the survey with 34.4% of survey respondents agreeing or strongly agreeing that they have concerns about how to justify collaborations with HiAP to senior managers. In response to the open ended survey questions, difficulty in convincing managers of the potential benefits of collaborating with HiAP was linked to a persistence of siloed thinking about core business, and the impact of this on structures of accountability. I think the main barrier for HiAP is lack of genuine commitment from senior management. This is because Chief Executives are held accountable for their core business. E.g. they have to report on how they are implementing SASP targets they are directly responsible for. Implementing HiAP is seen as an add on and not directly related (or at all) to achieving the KPIs by which they live and die by. HiAP is someone else’s KPI. (2013 survey, public servant from sector other than Health) Greaves and Bialystok (Greaves and Bialystok, 2011) claim that such siloed thinking is inherent within governments, and that it can threaten the potential for, and of, intersectoral partnerships. Our findings suggest that the ‘myopia’ referred to by Bacigalupe et al. (Bacigalupe et al., 2010) encourages short-term thinking in departments, spurred on by a political focus on satisfying department-specific performance indicators. Resource constraints Participants frequently raised concerns about the politically driven constrained fiscal environment and its potential impact on future opportunities for intersectoral work. Even participants who were positive about the benefits of collaborating with HiAP felt that their capacity to do so may be reduced in future. Over a quarter of the interview participants expressed dismay at regular and severe funding cuts being made within their departments, based on the rationale of achieving savings rather than on optimizing work processes or increasing eventual impact. Survey respondents also reported high workloads within which collaborative work could be considered to add unnecessary pressure. Currently there is a retreat to ‘core business’ and a narrower scope of health services. I think this removes the mandate to work in this way. Also it takes time to build awareness and partnerships and the staffing is lean and workloads high! So this work harder to do’. (2013 survey, public servant from Health) Several interview participants viewed fiscal restraint as a threat because it often stimulated a focus on narrowly defined work to satisfy short-term imperatives. This is particularly relevant to HiAP because our findings indicate T. Delany et al. that, even within the Health sector, health promotion, the pursuit of equity and future social improvement are usually cast outside of definitions of what constitutes core business given the dominance of short-term thinking and narrowly focussed constructions of what constitutes ‘efficiency’. . . . within a government climate where resources are more and more scarce and budgets are tighter and tighter the tendency will be always looking to where you can kind of make efficiencies and somewhere like Health will be really trying to be clear on what its focus is, and it’s really going to be about hospitals and sick people I would imagine, so that then always would mean that areas like Health in All Policies are always going to be a little bit on the outer of that . . . it is a nice thing to do when you have the resources in place to be able to do it. (Interview, public servant from a sector other than Health) Seven interview participants felt discouraged to continue engagement with HiAP where, despite worthy strategies being developed through the HiAP projects, they could not envisage the work having any impact on the future actions of their Departments due to limited budgets. . . . we did put up some ideas around creating some sort of more system wide reforms, working with the sector a lot more closely . . . but of course all of those things require resources and I don’t think that we’re going to see them anywhere in the future . . . I think you take your learning. I’ve untied myself . . . (Interview, public servant from a sector other than Health) Duration of HLA projects Approximately one quarter of interview participants discussed the length of time that HiAP’s HLA projects took. Seven participants explained that they could understand why some stages of HLA projects took time to complete given complexities in working intersectorally, in managing large collaborations and in attempting to navigate complex, hierarchical and frequently changing political and organizational environments. The amount of time taken was interpreted by some participants as an asset that enables people collaborating under the HiAP approach to establish trust and to follow the work through to completion (depending on how completion is defined within a given project, because the end point is tailored to the project). However, nine interview participants indicated that HLA projects can be too lengthy, due in particular to staffing changes, increases in workloads across sectors and, in some cases, a lack of clarity about the work plan. This sometimes resulted in missed opportunities, particularly if departmental or Government priorities shifted during the course of the project work. Health in All Policies in South Australia When we drafted the initial report and recommendations, I put them up to our Chief Executive and to our Minister. They were happy with it, signed off, sent through. By the time we came to actually then finalising that report, it was months after. My Chief Executive then said ‘no, I’m not signing off on this’. In that time the budget cuts had impacted. I think there is significant pressure on our Department to find savings and the response from my CE was ‘this isn’t core business. We’re not doing it’. (Interview, public servant from a sector other than Health) Frustrations over timeliness led several interview participants to reflect on how they believe future work could be managed. I would put a time limit on it and I would get involved more to create more of a structure to our working group rather than just letting things drift with everybody’s schedules. (Interview, public servant from a sector other than Health) [If we] suspect that the politics and the commitments aren’t going to add up and we’re not going to achieve anything maybe it’s time to sort of say ‘well, you know we’ve invested – we’ve agreed some things that haven’t happened. They’re not going to happen in the current political environment so let’s put our effort somewhere else’. (Interview, senior public servant from Health) CONCLUSION AND PRINCIPLES TO INFORM FUTURE HIAP PRACTICE The empirical findings reported in this paper can inform the future implementation of HiAP in SA, facilitating its movement towards becoming a more embedded, and systemic, part of policy-making process. Figure 2 summarizes the key elements that have supported HiAP 895 implementation in SA between 2007 and 2013. It also highlights the potential for development of an even stronger foundation for HiAP implementation through a focus on garnering support, improving timeliness and devising ways to emphasize the cost-effectiveness of HiAP outputs across the Government. The findings are also relevant to HiAP approaches in international contexts. While it is important to consider the role of specific political, cultural and geographic contexts when planning HiAP implementation, it is also possible to draw some generalizable principles from case study research undertaken in specific contexts providing that the research is developed through reliable and rigorous methods (Patton, 2002; Yin, 2014). Several such principles can be drawn from HiAP experience in SA. Dedicating staff and adequate financial resources is important for the HiAP approach to be feasible The benefits arising from the provision of a dedicated group of staff in SA highlight the importance of the provision of focussed resources—a factor highlighted in previous research that has shown that inadequate financial and staffing resources have the potential to impede HiAP collaborations (van der Heiden, 2010; Ollila, 2011; Bostic et al., 2012; McDaid, 2013; Rudolph et al., 2013a). While it may not always be possible to dedicate a unit to HiAP work, and while containing the work to a distinct unit may have some impact on the broader integration of HiAP across the Health sector, our findings indicate that in SA the Unit was a valued resource, particularly while the approach was being introduced across the Government, and while collaborative relationships were being established. A central mandate is a key facilitator of HiAP Fig. 2: Interrelated elements that have operated during the implementation of HiAP in South Australia 2007–2013. This research has confirmed that mandates for action from the central agency of government facilitate implementation of, and departmental commitment to, HiAP. These findings resonate with the existing literature (St-Pierre, 2009; Merkel, 2010; Gawith, 2012; Storm et al., 2013). However, reflection on the SA experience makes clear that mandates do not need to be used as what St-Pierre (St-Pierre, 2009) calls ‘coercive measures’. Instead a central agency mandate can form part of an authorizing environment for HiAP, allowing collaborations to develop more organically, with mutual learning and negotiation rather than being forced. Legislative frameworks that legitimize collaboration across government to work on shared targets, such as the SA Strategic Plan, the State Governments’ Seven Strategic Priorities and the SA Public Health Act, add power to mandates from central T. Delany et al. 896 government. In the South Australian context, the SA Public Health Act was being developed during the early implementation of HiAP and its architecture was informed by HiAP principles. Now, it provides a legislative mandate for HiAP and provides a range of mechanisms that may allow HiAP approaches to be systematically adopted across State and Local Governments, thereby, possibly, increasing the scope and potential for HiAP work. Collaborators require clearly defined timelines and achievement milestones to support HiAP feasibility The findings reinforce existing research which indicates that the appeal of participating in a HiAP partnership may be diminished due to the long-term nature of the approach (Nutbeam, 1994; Leppo and Tangcharoensathien, 2013; Wagenaar and Burris, 2013). The current model of establishing collaborative relationships applied within the SA context can be lengthy and may, therefore, conflict with the need to deliver outcomes that meet expectations in a political context driven by siloed structures of accountability, short-term agendas and a focus on achieving savings. Drawing on the strategies suggested by research participants, these problems may be overcome by building greater structure into the management of projects across sectors and ensuring that all collaborators set aside time in their schedules to dedicate to the project. It may also be beneficial to build recognizable achievement milestones into project timelines (Nutbeam, 1994). Achievement milestones will provide ‘signposts’ that help collaborators to recognize what the intended outcomes are during each stage of the project, thereby facilitating continued engagement and enhancing clarity. Demonstrating progress towards each milestone may also help staff justify their ongoing participation to senior management by providing evidence of the mutual gains that are being achieved. The dominance of siloed decision-making and narrow definitions of core business threatens HiAP success and reduces HiAP acceptance Our findings draw attention to an enduring barrier to HiAP: namely the current dominance of policy frameworks that focus the attention of senior decision-makers on targets defined within the existing siloed structures of government. In the SA context, the SA Strategic Plan does facilitate intersectoral action to further progress towards targets; however, accountability for meeting targets remains with single departments. This re-emphasizes the importance of horizontal mechanisms that encourage inter-agency partnerships and accountability across governments in the pursuit of shared societal, rather than simply departmental, goals (Rudolph et al., 2013b). However, if intersectoral collaboration towards achieving long-term social improvement does not feature as a core business goal this has the potential to threaten HiAP implementation. This is a recurrent theme in the literature where it is evident that a climate of economic uncertainty compounded by narrowly defined conceptions of core business within public agencies is not one where policy driven efforts to promote health and increase equity can flourish (Baum et al., 2013).
