The increasing adoption of cloud computing is the major driver for the expansion of the cloud-based segment of the market. According to a survey by RightScale (2016), nearly 95% of organizations run cloud-based applications. The hardware of electronic medical record (EMR) systems offered by different vendors are different. Hence, developing a standard CDSS software, which can run on multiple EMR systems, is a major challenge. Moreover, cloud-based applications are not dependent on web browsers, which makes them scalable and inherently safer than web-based applications.

Furthermore, according to the Organization for Economic Co-operation and Development (OECD) survey report, in 2018 average per capita health expenditure in Switerzland was about USD 7,317 in Norway USD 6,187 and Australia USD 5,005 respectively. Due to high healthcare expenditure across the world, the rising demand to reduce healthcare expenditure which shows a positive impact on the market.

In a cloud-based clinical decision support system, processing units are hosted on remote servers, which can be located in multiple data centers across the world, making them less vulnerable to cyberattacks. Besides, the increasing availability of cloud technology, coupled with its flexibility and scalability, is expected to drive the usage of cloud-based CDSS, over the forecast period.

Factors, such as the rise in technological advancement in the CDSS market, high awareness among patients, and increasing investments in HCIT solutions in North America, are expected to boost the growth of the CDSS market over the forecast period.

In 2016, the Agency for Healthcare Research and Quality (AHRQ) launched a new initiative to disseminate and implement the findings of patient-centred outcomes research (PCOR) through clinical decision support (CDS). The two major goals of the initiative were to accelerate the movement of evidence into practice through CDS and to make CDS more shareable, standards-based, and publicly available. Such research efforts help engage relevant stakeholders, such as patients, clinicians, provider organizations, guideline and quality measurement developers, and information technology professionals, to improve decision making in healthcare with the help of CDSS. Such initiatives are expected to propel the growth of the CDSS market, over the forecast period, in North America.
