The Centers for Medicare & Medicaid Services (CMS) is increasing its emphasis on the use of clinical decision support (CDS) tools, recognizing its role in reducing care costs and improving care quality. Clinicians who have already adopted CDS systems tend to agree they can help significantly. CDS can also deliver suggestions based on evidence-based best practices from which the clinician is in the process of deviating, as evidenced by EMR documentation entries. So, the advantages of using an advanced CDS system fall into four general “reducing” categories: 1) Reducing the rate of medical errors 2) Reducing unnecessary or duplicate testing 3) Reducing length of stay and instances of hospital-acquired conditions 4) Reducing hospital readmissions.
