Uncovering the processes of knowledge transformation: the example of local evidence-informed policy-making in United Kingdom healthcare.

BACKGROUND: Healthcare policy-makers are expected to develop 'evidence-based' policies. Yet, studies have consistently shown that, like clinical practitioners, they need to combine many varied kinds of evidence and information derived from divergent sources. Working in the complex environment of healthcare decision-making, they have to rely on forms of (practical, contextual) knowledge quite different from that produced by researchers. It is therefore important to understand how and why they transform research-based evidence into the knowledge they ultimately use. METHODS: We purposively selected four healthcare-commissioning organisations working with external agencies that provided research-based evidence to assist with commissioning; we interviewed a total of 52 people involved in that work. This entailed 92 interviews in total, each lasting 20-60 minutes, including 47 with policy-making commissioners, 36 with staff of external agencies, and 9 with freelance specialists, lay representatives and local-authority professionals. We observed 25 meetings (14 within the commissioning organisations) and reviewed relevant documents. We analysed the data thematically using a constant comparison method with a coding framework and developed structured summaries consisting of 20-50 pages for each case-study site. We iteratively discussed and refined emerging findings, including cross-case analyses, in regular research team meetings with facilitated analysis. Further details of the study and other results have been described elsewhere. RESULTS: The commissioners' role was to assess the available care provision options, develop justifiable arguments for the preferred alternatives, and navigate them through a tortuous decision-making system with often-conflicting internal and external opinion. In a multi-transactional environment characterised by interactive, pressurised, under-determined decisions, this required repeated, contested sensemaking through negotiation of many sources of evidence. Commissioners therefore had to subject research-based knowledge to multiple 'knowledge behaviours'/manipulations as they repeatedly re-interpreted and recrafted the available evidence while carrying out their many roles. Two key 'incorporative processes' underpinned these activities, namely contextualisation of evidence and engagement of stakeholders. We describe five Active Channels of Knowledge Transformation - Interpersonal Relationships, People Placement, Product Deployment, Copy, Adapt and Paste, and Governance and Procedure - that provided the organisational spaces and the mechanisms for commissioners to constantly reshape research-based knowledge while incorporating it into the eventual policies that configured local health services. CONCLUSIONS: Our new insights into the ways in which policy-makers and practitioners inevitably transform research-based knowledge, rather than simply translate it, could foster more realistic and productive expectations for the conduct and evaluation of research-informed healthcare provision.

Evidence based policy making and the 'art' of commissioning - how English healthcare commissioners access and use information and academic research in 'real life' decision-making: an empirical qualitative study.

BACKGROUND: Policymakers such as English healthcare commissioners are encouraged to adopt 'evidence-based policy-making', with 'evidence' defined by researchers as academic research. To learn how academic research can influence policy, researchers need to know more about commissioning, commissioners' information seeking behaviour and the role of research in their decisions. METHODS: In case studies of four commissioning organisations, we interviewed 52 people including clinical and managerial commissioners, observed 14 commissioning meetings and collected documentation e.g. meeting minutes and reports. Using constant comparison, data were coded, summarised and analysed to facilitate cross case comparison. RESULTS: The 'art of commissioning' entails juggling competing agendas, priorities, power relationships, demands and personal inclinations to build a persuasive, compelling case. Policymakers sought information to identify options, navigate ways through, justify decisions and convince others to approve and/or follow the suggested course. 'Evidence-based policy-making' usually meant pragmatic selection of 'evidence' such as best practice guidance, clinicians' and users' views of services and innovations from elsewhere. Inconclusive or negative research was unhelpful in developing policymaking plans and did not inform disinvestment decisions. Information was exchanged through conversations and stories, which were fast, flexible and suited the rapidly changing world of policymaking. Local data often trumped national or research-based evidence. Local evaluations were more useful than academic research. DISCUSSION: Commissioners are highly pragmatic and will only use information that helps them create a compelling case for action.Therefore, researchers need to start producing more useful information. CONCLUSIONS: To influence policymakers' decisions, researchers need to 1) learn more about local policymakers' priorities 2) develop relationships of mutual benefit 3) use verbal instead of writtencommunication 4) work with intermediaries such as public health consultants and 5) co-produce local evaluations.

Lipoprotein(a) is associated differentially with carotid stenosis, occlusion, and total plaque area.

BACKGROUND: Lipoprotein(a) [Lp(a)] is a putative risk factor for myocardial infarction and stroke and is related to thrombosis and impaired fibrinolysis. We studied relationships of Lp(a) with carotid stenosis, occlusion, and total plaque area, distinct phenotypes of atherosclerosis that may be differentially affected by cardiovascular risk factors. METHODS AND RESULTS: Multivariable linear regression analysis was used to study relationships of Lp(a) to phenotypes of carotid atherosclerosis among 876 consecutive patients from an atherosclerosis prevention clinic with complete data for all variables used in the model. Occlusion of an internal carotid artery was present in 22 (2.5%) patients (one with bilateral occlusions). Risk factors predicted carotid plaque area, stenosis, and occlusion differently. Lp(a) was a significant independent predictor of baseline stenosis (P<0.0001) but not of plaque area (P=0.13); in logistic regression, Lp(a) significantly predicted occlusion (P=0.001). Patients with occlusion had significantly higher levels of Lp(a): 0.27+/-0.25 g/L versus 0.17+/-0.18 g/L without occlusion; P=0.007. CONCLUSIONS: Lp(a) was a significant independent predictor of carotid stenosis and occlusion, but not of carotid plaque area, supporting the hypothesis that the effect of Lp(a) on atherogenesis and cardiovascular risk is largely related to thrombosis and impaired fibrinolysis. Stenosis and occlusion may not be attributable to plaque progression, but to plaque rupture and thrombosis; this relationship may also apply to other arterial beds.

Discourses of joint commissioning.

Increasing attention has focused on the role of joint commissioning in health and social care policy and practice in England. This paper provides an empirical examination of the three discourses of joint commissioning developed from an interpretative analysis of documents by Dickinson et al. (2013; BMC Health Services Research, 13) and applied to data from our study exploring the role of knowledge in commissioning in England. Based on interviews with 92 participants undertaken between 2011 and 2013, our analysis confirms that the three discourses of prevention or empowerment or efficiency are used by professionals from across health and social care organisations to frame their experiences of joint commissioning. However, contrary to Dickinson et al., we also demonstrate that commissioners and other stakeholders combine and trade off these different discourses in unexpected ways. Moreover, at sites where the service user experience was central to the commissioning process (joint commissioning as empowerment), a greater sense of agreement about commissioning decisions appeared to have been established even when the other discourses were also in play.

What do external consultants from private and not-for-profit companies offer healthcare commissioners? A qualitative study of knowledge exchange.

OBJECTIVES: The use of external consultants from private and not-for-profit providers in the National Health Service (NHS) is intended to improve the quality of commissioning. The aim of this study was to learn about the support offered to healthcare commissioners, how external consultants and their clients work together and the perceived impact on the quality of commissioning. SETTING: NHS commissioning organisations and private and not-for-profit providers. DESIGN: Mixed methods case study of eight cases. DATA COLLECTION: 92 interviews with external consultants (n=36), their clients (n=47) and others (n=9). Observation of 25 training events and meetings. Documentation, for example, meeting minutes and reports. ANALYSIS: Constant comparison. Data were coded, summarised and analysed by the research team with a coding framework to facilitate cross-case comparison. RESULTS: In the four contracts presented here, external providers offered technical solutions (eg, software tools), outsourcing and expertise including project management, data interpretation and brokering relationships with experts. In assessing perceived impact on quality of commissioning, two contracts had limited value, one had short-term benefits and one provided short and longer term benefits. Contracts with commissioners actively learning, embedding and applying new skills were more valued. Other elements of success were: (1) addressing clearly agreed problems of relevance to managerial and operational staff (2) solutions co-produced at all organisational levels (3) external consultants working directly with clients to interpret data outputs to inform locally contextualised commissioning strategies. Without explicit knowledge exchange strategies, outsourcing commissioning to external providers resulted in the NHS clients becoming dependent. CONCLUSIONS: NHS commissioning will be disadvantaged if commissioners both fail to learn in the short term from the knowledge of external providers and in the longer term lose local skills. Knowledge exchange mechanisms are a vital component of commissioning and should be embedded in external provider contracts.
