Cardiovascular Disease• Cardiovascular disease (CVD) accounts for 1 in every 3 deaths in the United States (Roger et al., 2012)• CVD is projected to increase by 10% over the next 20 years (Heidenreich et al., 2011)• CVD accounts for 20% of healthcare dollars spent and a 3-fold increase in these expenditures is expected (Trogdon, Finkelstein, Nwaise, Tangka, & Orenstein, 2007)
Clinical Decision SupportSystems (CDSS)• Clinical Decision Support Systems (CDSS) are defined as clinical consult systems that use population statistics or encode expert knowledge to assist healthcare professionals in the diagnosis and treatment of disease (Shortliffe & Cimino, 2006)• CDSSs have been reported to improve the quality of care delivered and health outcomes (Kawamoto, Houlihan, Balas, & Lobach, 2005)
CDSS and CVD• Numerous guidelines exist for the treatment of CVD• Many practitioners are not appropriately reaching quality measures (Brady, Oliver, & Pittard, 2001)• CDSSs could possibly improve patient care and reduce the heavy financial burden of CVD• This paper explored the data that has been reported concerning the use of CDSSs and their impact on CVD-related care
Congestive Heart Failure• Mudge et al. showed that CDSSs reduced mortality in CHF patients (Mudge et al., 2010).• Toth-Pal et al. showed that general physicians are able to manage CHF patients with a CDSS (Toth- Pal, Wardh, Strender, & Nilsson, 2008).• Riggio et al. found that ACEIs were more likely to be prescribed upon discharge after MI with a CDSS that was simultaneously linked with the EMR (Riggio et al., 2009).• Eckstein et al. showed that paramedics in the field were capable of diagnosing CHF and treating it when symptoms were linked to a CDSS (Eckstein & Suyehara, 2002).
Hypertension• Bosworth et al. showed that physicians that used CDSSs to treat hypertensive patients were more likely to abide by the national guidelines but not improve blood pressure numbers (Bosworth et al., 2009)• Hicks et al. found similar results (Hicks et al., 2008)• Both of these studies show that CDSSs are not actually able to improve the blood pressure of hypertensive patients but improve guideline adherence
Dyslipidemia• Gilutz et al. showed that CDSSs were able to improve the cholesterol values of patients with known coronary artery disease (CAD)• Increased secondary prevention and possible reduction in MI needs to be researched further
Myocardial Infarction• Riggio et al. found that adherence to evidence-based guidelines was improved with increases in prescriptions for ACEIs (Riggio et al., 2009)• These drugs have been shown to reduce mortality
Areas of Uncertainty• Only a few of the studies in this report were randomized controlled trials • It does appear that CDSSs can improve the care of patients with CVD but studies with a higher level of design will be needed• The studies discussed did not investigate the cost of implementing CDSSs• These studies did not look at long-term outcomes• There was no uniformity in CDSSs used between studies
Conclusion• CDSSs have a benefit in the management of patients with CHF and are also able to reduce mortality in these patients• CDSSs are not able to actually improve the treatment of hypertensive patients but may increase adherence to evidence-based guidelines• CDSSs are able to improve the management of patients with dyslipidemia• CDSSs improve the prescription practices of patients that are discharged from the hospital after MI
