The HTA process is formal, systematic and transparent, and uses up-to-date methods to consider the best available evidence - from people's lived experiences and 'real-world' data, to randomised controlled trials and systematic reviews.
The dimensions of value for a health technology often include clinical effectiveness, safety, cost effectiveness (health economics), and the views of patients and healthcare professionals, as well as wider implications for the healthcare system. These dimensions are assessed by examining the intended and unintended consequences of using a health technology compared to existing alternatives. The overall value may vary depending on the decision context.
HTA can be applied at different points in the lifecycle of a health technology, i.e. pre-market, during market approval, post-market, through to the disinvestment of a health technology.
