Indian medical device industry Health systems throughout the world, whether in developed or developing countries, are struggling with the challenge of how to manage health-care delivery in conditions  of resource constraint. Healthcare policy, practice and decisions are needed to maximize the positive impact of health-care interventions on population health,while maximizing the value from the cost of providing the interventions.HTA is the systematic evaluation of properties, effects, and/or impacts of health technology. Its main purpose is to inform technology-related policy-making in health care, and thus improve the uptake of cost-effective new technologies and prevent the uptake of technologies that are of doubtful value for the health system. It is one of three complementary functions to ensure the appropriate introduction and use of health technology. The other two components are regulation, which is concerned with safety and efficacy, and assessment of all significant intended as well as unintended consequences of technology use; and management, which is concerned with the procurement and maintenance of the technology during its life-cycle. The performance of health systems is strengthened when the linkages and exchange among these elements are clearly differentiated but mutually supportive.
