Epistemic communities are an established concept in the study of international relations but can also explain policy change at the domestic level. This article asks why some epistemic communities manage to convince decision makers of their preferred policies while others do not. It suggests that the reason lies in the causal mechanism of epistemic communities' influence on decision makers, mediated by decision makers' demand for expert input. Most epistemic communities scholarship focuses on single case studies where the communities' influence on policy was strong and clear, leading to an overestimation of the groups' influence. To help correct this probable bias, this article compares a successful case of epistemic community influence (health technology assessment in Poland) with an unsuccessful example of the same policy (in the Czech Republic). The juxtaposition allows for unpacking of the necessary parts of the causal mechanism (emergence of an epistemic community, its activity, access to decision makers, and successful suasion) and separating them from the crucial scope condition. Decision makers' uncertainty about the policy issue at hand has traditionally been the key scope condition for epistemic communities but the successful Polish case demonstrates that epistemic communities can be influential even in highly certain areas of routine policymaking, leading to a reconceptualization of uncertainty as policymakers' demand for expert input. Demand can originate from various sources, but any change of it affects individual parts of the causal mechanism, leading to a success or failure of epistemic communities' policy enterprise.

This paper analyses the politics of regulatory expansion within the diagnostics sector. Since 1990, an informal, clinician-led process of diagnostic innovation within the UK NHS has been challenged by new mechanisms for the evaluation of diagnostics. We describe these diagnostic reforms as a process of fragmented regulatory expansion. New governance mechanisms function as regulatory niches: discrete spaces within an overarching sociotechnical regime. The boundaries of regulatory niches are organisational and epistemological. Organisational boundaries map onto established communities of practice that constitute the regulatory target; epistemological boundaries are defined by distinctive evaluation frameworks. Niches are also distinguished by their outcomes (rate of positive decisions) and their origins. Niche formation was triggered by five drivers: public scandal; technological change; marketisation; institutional isomorphism; and transnational policy transfer. Each niche was triggered by a unique confluence of these drivers, but common to all were historic shifts in healthcare politics, as the rise of evidence-based medicine intersected with the centralising impulse of the regulatory state, which encroached on clinical autonomy in a contest for power that is increasingly mediated by influential non-governmental organisations. ; ERC 716689

BACKGROUND: Social scientists have paid increasing attention to health technology assessment (HTA). This paper provides an overview of existing social scientific literature on HTA, with a focus on sociology and political science and their subfields. METHODS: Narrative review of key pieces in English. RESULTS: Three broad themes recur in the emerging social science literature on HTA: the drivers of the establishment and concrete institutional designs of HTA bodies; the effects of institutionalized HTA on pricing and reimbursement systems and the broader society; and the social and political influences on HTA decisions. CONCLUSION: Social scientists bring a focus on institutions and social actors involved in HTA, using primarily small-N research designs and qualitative methods. They provide valuable critical perspectives on HTA, at times challenging its otherwise unquestioned assumptions. However, they often leave aside questions important to the HTA practitioner community, including the role of culture and values. Closer collaboration could be beneficial to tackle new relevant questions pertaining to HTA.

European governments employ sophisticated health technology assessment and regulatory procedures to identify which pharmaceuticals to fund publicly. However, there are persisting demands from patients for those drugs excluded from positive reimbursement lists, leading to the emergence of what are here termed "alternative access schemes". This paper presents a purposive review of these schemes based on available scholarly and grey literature, illustrated with real-world examples from recent practice. It puts forward an original typology of alternative access schemes based on their marketing authorization (regulation) and reimbursement (redistribution) status. We describe the complex, multidimensional policy trade-offs between the principles of patient freedom of choice, clinical autonomy, encouragement of innovation, evidence-informed decisions on safety and quality, access to treatment, and financial sustainability, involved in marketing authorization and reimbursement decisions. We discuss the ways in which alternative access schemes differ and conclude that our typology can illuminate salient policy dilemmas raised by alternative access schemes in national drug reimbursement systems.

Health technology assessment (HTA) is not simply a mechanistic technical exercise as it takes place within a specific institutional context. Yet, we know little about how this context influences the operation of HTA and its ability to influence policy and practice. We seek to demonstrate the importance of considering institutional context, using a case study of Hungary, a country that has pioneered HTA in Central and Eastern Europe. We conducted 26 in-depth, semi-structured interviews with public and private sector stakeholders. We found that while the HTA Department, the Hungarian HTA organisation, fulfilled its formal role envisaged in the legislation, its potential for supporting evidence-based decision-making was not fully realised given the low levels of transparency and stakeholder engagement. Further, the Department's practical influence throughout the reimbursement process was perceived as being constrained by the payer and policymakers, as well as its own limited organisational capacity. There was also scepticism as to whether the current operational form of the HTA process delivered "good value for money". Nevertheless, it still had a positive impact on the development of a broader institutional HTA infrastructure in Hungary. Our findings highlight the importance of considering institutional context in analysing the HTA function within health systems
