Market Growth Factors

The increasing use of electronic health records (EHRs) and integrated information systems has contributed considerably to the demand for CDSS. For example, in the United States, almost 88% of office-based physicians were using an EHR system in 2021. Of these, 78% had certified EHR systems. Incorporating CDSS into the EHR provides real-time evidence-based decision support to providers at the point of care, which can help reduce errors in patient care.

The increasing prevalence of chronic diseases like diabetes, cardiovascular disease and cancers is impacting the growth of the market. These diseases account for 74% of global deaths, and require more advanced and personalized treatment approaches. With an aging population and increased risk of polypharmacy in patients with multimorbidity, CDSS technologies would provide physicians with evidence-based guidelines and tailored interventions.

The development of artificial intelligence (AI) and machine learning (ML) has expanded upon the possibilities of CDSS, allowing these systems to use large clinical datasets, including medical imaging and genomic information. AI-accelerated CDSS can improve the diagnosis by classifying heart rhythms and providing personalized predictions to improve clinical outcomes. The market is driven by the combination of these technologies, regulatory framework, and personalized medicine demand.
