Risk Stratification of Patients Presenting With Chest Pain in the Emergency Department: A Quality Improvement...

Chest pain is a leading cause of emergency department visits worldwide. At a Midwest urban level 1 trauma center, chest pain accounts for an average of 2530 emergency department visits annually and constitutes the highest number of observation admissions. This quality improvement initiative aimed to educate emergency nurses and implement an evidence-based chest pain pathway to reduce observation admissions and decrease length of stay.

Emergency nurses completed pre- and post-education surveys. Educational sessions, delivered both online and in-person, were provided based on the results of a pre-survey. An evidence-based chest pain pathway was implemented. Patients' electronic health records were reviewed and analyzed.

Emergency nurses' chest pain knowledge significantly improved after education [χ² (1) = 6.125; P =.008]. The admission rate (observation and inpatient) among patients meeting the inclusion criteria decreased from 31.16% to 28.55%. The emergency department discharges increased from 68.84% to 71.45%. The length of stay did not significantly increase (P = .89). By sustaining the 2.61% increase in discharges, there is a projected annual variable cost savings of $104,544.66.

This quality improvement initiative resulted in increased knowledge among emergency nurses. This was clinically significant given that it enhanced interdisciplinary collaboration, facilitating an increase in discharges among patients with chest pain. Furthermore, this initiative improved transitions of care across different settings. Future work is recommended to assess the applicability of the initiative and the sustainability of results in other organizations.
