Introduction/Background/Significance: Clinical decision support systems (CDSS) use information and communication technologies developed through evidenced-based methodologies such as algorithms and logical regression to provide relevant knowledge and information to providers to assist with the decision making process to support the health care and clinical outcomes of the patient. Common formats of CDSS include alerts and ‘pop-up’ messages. The overall success of the CDSS depends on five stages. Each stage builds on the previous stage and the lowest two factors impacting success include firing rates and override rates. This literature review seeks to evaluate the relationship between the two factors of alert fatigue and alert overrides to the success of CDSS.

Problem/Purpose Statements: The problem is that electronic medical record (EMR) systems which actively depend on CDSS generally have a large quantity of alerts and these alerts have been shown to create alert fatigue for providers. Given the significance of alert fatigue and the potential negative outcomes that result from alert overrides, the aim of this systematic literature review is to answer three questions: Does the use of CDSS when used in the care of a patient improve clinical outcomes?, Is there a threshold with the level or quantity of alerts that has been shown to create provider alert fatigue?, Is there a relationship between the number of CDSS alert messages presentations and the frequency rate of alert overrides?

Methods: The literature search focused on two databases using key search terms and Boolean operators. Sixteen articles (n = 16) were utilized after the inclusion and exclusion criteria were applied, abstract and full-text reviews were assessed for significance to the research purpose and quality assessments were completed. A data collection matrix was used to organize the data.

Results/Findings: Several benefits were found to support the use of CDSS to support clinical outcomes. Precautions and possible consequences were also identified. Several theories were identified which explain the alert fatigue phenomenon. Several recommendations for both CDSS and alert design and implementation were identified.

Discussion/Conclusions: Subgroup analysis did not provide enough evidence at this time to conclude that quantity alone can explain the relationship between CDSS alert messages presentations and the frequency of alert overrides. Best practice guidelines and recommendations are provided for CDSS and alert design and implementation as well as recommendations for the use of CDSS in conjunction with health information technologies (HITs) to support decision making processes. This literature review has implications for designers, implementation specialists, system analysts and additional health informatics (HI) professionals. Additionally, it adds value to the existing knowledge base surrounding CDSS while presenting areas for further research to examine additional heterogeneous factors which may impact the success of CDSS.
