Life Cycle Of A Health Information System – 12 Slides
Health Technology Assessment (HTA) is “the systematic evaluation of the properties and effects of a health technology, addressing the direct and intended effects of this technology, as well as its indirect and unintended consequences, and aimed primarily at informing health technology decision making.” Healthcare systems have viewed the introduction of healthcare technologies as a linear process in which various stakeholders (innovators, manufacturers, regulators, healthcare technology assessors, reimbursement bodies, healthcare providers, healthcare professionals, patients, and citizens) interacted at each stage but were not involved in a continuous dialogue and knowledge exchange. This step-by-step approach generates inefficiency in many cases by, among other things, isolating innovators from actual healthcare needs, introducing health technologies of dubious value, generating unnecessary variability in practice, maintaining no-added-value practices, and disregarding knowledge out of practice. These circumstances imply inefficient resource and investment allocation, a hole in the waterline of healthcare systems and their sustainability, and a non-direct relationship between expected or theoretical outcomes and actual health outcomes. Various initiatives have been implemented recently to mitigate the effects of the abovementioned issues.
