With a mission "to assist and advise healthcare decisionmakers in defining health policies at all levels", [ 13] HTA acts as a bridge between evidence and decisionmaking to ensure better synthesis, communication and dissemination of information [ 14].
We developed a method of assessing the degree of alignment between Government policies and the 'evidence base', involving: reviewing theoretical frameworks; analysis of policy documents, and nineteen in-depth interviews with policymakers which explored influences on, and barriers to cross-cutting policymaking and the use of research evidence in decisionmaking.
Summary data from observational studies was included if they reported final height, based on the assertion that considering both types of evidence better informs decisionmaking [ 38].
MCDA, HTA, and knowledge translation have a common objective: enlightened and evidence-based healthcare decisionmaking.
The EVIDEM framework is proposed as a step beyond the current cost-effectiveness model, combining efficient HTA, pragmatic MCDA, and an ethical framework to ensure systematic consideration of all components of decisionmaking and evidence available, and to provide a transparent record of how these elements have been used to reach a decision.
This study also revealed that strength of evidence is an important aspect in decisionmaking, highlighting the influence of evidence-based medicine.
This paper summarizes several iterations in developing a compact set of four key principles for successful systems engineering, which are 1) Stakeholder Value-Based System Definition and Evolution 2) Incremental Commitment and Accountability 3) Concurrent Multidiscipline System Definition and Development, and 4) Evidence-Based and Risk-based Decisionmaking.
Evidence-based decisionmaking relies on actual benefits derived from an intervention so mechanisms (such as defining subcriteria) outlining specifically the most relevant outcomes of efficacy/effectiveness in real life are critical to ensure that the dimensions of efficacy/effectiveness are fully captured and communicated.
The EVIDEM framework promotes transparent and efficient healthcare decisionmaking through systematic assessment and dissemination of the evidence and values on which decisions are based.
