HTA is used to support decisions at a national, regional, local or individual patient level about what interventions to provide and use. HTAs are used to support national-level policy decisions. Findings of HTA may also influence patient eligibility for an intervention, the setting in which it is provided, and how it might be administered. Within local settings (eg hospital group) HTAs may be used to inform decisions about which products to use. HTA is also used to support the development of clinical guidelines. Stakeholders who use HTA findings in Ireland can include policy makers, payers, providers, clinicians and patients, pharmaceutical companies, manufacturers of medical devices and equipment, and academics.
