could help provide correct orders, and alert providers to assist with getting our patients the right types of medical attention they need. Reference Nelson, R., & Staggers, N. (2018).

I think you made some good points about the barriers to implementing clinical decision support systems. The cost to acquire the software would be significant especially since their would not necessarily be a direct financial gain. If the hospital bought a new MRI machine you could see the decrease in wait time and increase in functionality. The adding of a CDS system could help the clinicians and staff provide patients with overall better care, but it would be hard to show financially how the system could be worth the large cost it would be. Alanna, Very thorough post about clinical decision support systems! As you mentioned a large amount of alerts can be being fired at healthcare providers, until they become desensitized and begin to ignore them all together. It can just become part of going through the motions. One of the bigger obstacles in regards to alert fatigue are clinical decision systems sending out the same alert more than once after it has been addressed, this is causing desensitization. In a study, it showed that with each additional alert from the same patient, a clinician became 30 percent less likely to address said alert. This became most evident with a patient with more comorbidities. (Ancker, Edwards, Nosal, Hauser, Mauer, Kaushal, & with the HITEC Investigator 2017s). It appears that we need to find a way to keep point of care alerts consistent, yet not repetitive. References: Ancker, J.
