Health Technology Assessment

What is a health technology assessment (HTA)?

A Health Technology Assessment (HAS) is a systematic evaluation of the properties and effects of a health technology. It aims to address the direct and intended effects of this technology, as well as its indirect and unintended consequences, which is mainly at informing decision making regarding health technologies.

Key questions in a HTA

Does the intervention work?
For whom?
At what cost?
How does it compare with the alternative?

What do we do?

HSR performs HTAs to support decision-making in three main areas: clinical service planning, programme development, and the Medical Device Oversight Committee (MDOC).

Area	What We Do	Examples of Past Reviews
Clinical service planning	Conduct rapid reviews for selected proposals submitted to the annual CGH Marketplace exercise Review strengthened decision making process within CGH senior management in their prioritization of proposals Conduct rapid reviews for CGH senior management Allow them to evaluate evaluate the quality of new programs using an evidence-based framework for onward submission to MOH for further review for funding	New sustainable model of care for chronic non-invasive ventilation to enhance patient care access, care quality, and health outcomes Neoveil polyglycolic acid mesh for pancreatic surgery Measures to mitigate the impact of COVID-19 on hospital services 3D HD flex tip laparoscopic system for abdominal surgery AirSeal valveless trocar system for advanced laparoscopic/robotic surgery Emergency department-initiated extracorporeal membrane oxygenation High-intensity focused ultrasound for benign fibroadenomas and benign thyroid nodules Intraoperative contrast enhanced ultrasound Integrated spinal surgery service with computer-guided, minimally invasive capability Integrated rehabilitation service for arthroscopic knee and shoulder surgery Rotational endarterectomy for coronary artery disease in patients with complex lesions of the coronary arteries
Programme Development	Conduct independent assessment of the evidence of programmers to be submitted by CGH staff, and assist programme directors to establish an evaluation framework for the clinical programme Support the Ministry of Health, Health Services Development Programme (MOH, HSDP), a competitive grant funding process, for the introduction and piloting of new technologies or services by the public healthcare institutions
MDOC	Conduct rapid reviews for decision making and the development of process and clinical outcomes to evaluate the performance of devices Support MDOC
