Description

Computerized clinical decision support systems (CDSS) are electronic tools that prompt provider behaviors in various areas of patient care, including medication ordering, chronic disease management, health care screening, and vaccination. CDSS can provide physicians, nurses, pharmacists, and other care providers with patient-specific prompts or warnings, treatment guidelines (e.g., order sets), automatic medication dosing calculators, or reports of overdue tests and medications as appropriate. These tools can be integrated with comprehensive electronic health record (EHR) systems, part of a computerized physician order entry (CPOE) system, or a standalone electronic interface; various types of CDSS exist for different workflows and settings, including primary, inpatient, acute, long term, and dental care.

Expected Beneficial Outcomes

Improved processes of care
Increased appropriate drug prescribing
Improved health outcomes
Improved patient safety

Evidence of Effectiveness

There is strong evidence that computerized clinical decision support systems (CDSS) improve processes of care (Niazkhani 2017, Ali 2016, Marasinghe 2015, CG-CVD, Bright 2012, Roshanov 2011, Roshanov 2011a, Sahota 2011, Souza 2011, Bryan 2008), particularly when used for drug prescribing and management (Simpao 2017, Baysari 2016, Jia 2016, Marasinghe 2015, Ranji 2014, Cochrane-Gillaizeau 2013, Stultz 2012, AHRQ-McKibbon 2011, Hemens 2011, Nieuwlaat 2011, Sahota 2011, Tawadrous 2011, Jamal 2009, Pearson 2009, Schedlbauer 2009, Wolfstadt 2008). Such systems have also been shown to improve patient outcomes in some circumstances (Varghese 2017, Borab 2017, Kooij 2017, Niazkhani 2017, Ali 2016, Jia 2016, Moja 2014, Nieuwlaat 2011, Roshanov 2011a, Sahota 2011, Souza 2011, Tawadrous 2011). Additional evidence is needed to confirm effects on patient outcomes.

CDSS can improve processes of care in primary care (Bryan 2008), long term care (Marasinghe 2015), and acute care settings (Bennett 2017, Sahota 2011), especially when systems support preventive services, prescribing therapies, and ordering of clinical studies (Bright 2012) and tests (Roshanov 2011a). CDSS can also improve processes for chronic disease management (Roshanov 2011) and preventive care, such as screening and management of asthma (Fathima 2014), high cholesterol (Souza 2011), and cardiovascular disease (CG-CVD). In some circumstances, such systems can improve processes related to cancer screening and referrals, and mental health conditions (Souza 2011).

Clinical decision support systems can increase compliance with recommendations, guidelines, and protocols in medication prescription (Simpao 2017, Borab 2017, Baysari 2016, Patel 2017), transplant care (Niazkhani 2017), and laboratory test ordering (Delvaux 2017, Ennis 2015), and decrease inappropriate testing (Hendrickson 2018, Felcher 2017, White 2017). CDSS may also benefit high risk groups, for example, decreasing inappropriate opioid prescribing among veterans (Patel 2017) and increasing safety planning for youth at risk of suicide (Reyes-Portillo 2018).

CDSS can improve medication management (Niazkhani 2017, AHRQ-McKibbon 2011), prescribing outcomes (Pearson 2009), and increase medication safety (Jia 2016, Marasinghe 2015). Combined with computerized provider order entry (CPOE), clinical decision support systems reduce medication prescribing errors (Ranji 2014, Stultz 2012, Schedlbauer 2009) and may also reduce adverse drug events (Stultz 2012, Wolfstadt 2008). Medication dosing advice via CDSS can improve some patient outcomes (Cochrane-Gillaizeau 2013, Sahota 2011) and increase physician compliance with guidelines (Tawadrous 2011, Jamal 2009, Georgiou 2007). Pharmacy-specific CDSS that address potential safety concerns are more effective than CDSS that promote compliance with evidence-based guidelines (Robertson 2010).

Frequent CDSS alerts, especially inappropriate alerts, lead to “alert fatigue” and may cause users to miss or ignore important alerts (Fathima 2014, Stultz 2012, Moxey 2010). These point of care reminders are more likely to improve clinical processes of care when providers are required to enter a response (Shojania 2010). Clinical decision support systems can be less effective when doctors do not follow system advice (Baysari 2016).

Clinical decision support systems have been shown to improve patient outcomes in some circumstances (Varghese 2017, Kooij 2017, Niazkhani 2017, Roshanov 2011, Sahota 2011, Souza 2011, Tawadrous 2011). CDSS appear most likely to improve patient outcomes when used to help manage chronic conditions (Kooij 2017) such as high cholesterol (Souza 2011) and diabetes (Ali 2016, Nieuwlaat 2011). Such systems can improve blood glucose when implemented as part of a complex hospital-based intervention (Nirantharakumar 2011). CDSS may also reduce adverse events (Varghese 2017, Borab 2017) and mortality in inpatient care (Varghese 2017).

Researchers suggest standardized content that can be easily updated and integration in an EHR to provide timely and appropriate support during workflows will increase the ability of CDSS to support diagnosis (Nurek 2015). The frequent need for customization on a site-by-site basis to meet organizational, departmental, and provider needs and practices, and lack of interoperability between different EHRs can be barriers to CDSS implementation (AHRQ-Mardon 2014). Recommendations for implementing CDSS and other e-health technologies include considering their complexity, adaptability, and compatibility with existing systems when selecting a system and involving key stakeholders early in the implementation process (Ross 2016).

The cost impacts of CDSS are unclear; some studies find decreases, some increases, and some no change in the cost of care (Jacob 2017, Kooij 2017, Fillmore 2013, Hemens 2011).

Implementation

United States

Many commercially produced EHRs include CDSS (ONCHIT-CDS), and organizations such as Brigham and Women’s Hospital and the Yale School of Medicine developed decision support systems as part of the AHRQ Clinical Decision Support Demonstration Projects (AHRQ-Mardon 2014).

Partners Healthcare System, an integrated system of hospitals in Massachusetts, uses CDSS to provide real-time reminders on guideline-based care recommendations for acute respiratory infections, CAD, and diabetes (AHRQ HCIE-Middleton).
