The global clinical decision support systems (CDSS) market size is calculated at US$ 3.69 billion in 2024, grew to US$ 4 billion in 2025, and is projected to reach around US$ 8.22 billion by 2034. The market is expanding at a CAGR of 8.34% between 2025 and 2034.
Growing advancements: There is a rise in the development of cloud-based or AI-powered CDSS. This is increasing their utilization, funding, and collaboration among the companies to detect various diseases and to provide effective treatment solutions. Moreover, to promote their use, the number of acquisitions is also increasing.
For instance,
In February 2025, after receiving the 10th FDA clearance, the CEO of Etiometry, Shane Cooke, stated that their leadership in clinical decision support and regulatory compliance will be strengthened, and their dedication to cybersecurity will be supported by this clearance. With increasing cybercrimes, the hospitals are demanding technologies with the FDA’s latest security standards and are adopting solutions that are not scrutinized, exposing them to unnecessary vulnerabilities. Thus, a solution that can enhance patient outcomes and protect their data and hospital systems will be provided by the company as per its mission.
