Exploring the Relationship Between Continuously Monitored Vital Signs, Clinical Deterioration, and Clinical Actions.

Area of Science:

• Medical Informatics
• Clinical Monitoring
• Patient Outcomes

Background:

• Continuous vital sign monitoring on general wards facilitates early interventions.
• Clinical actions are crucial for preventing patient deterioration.
• These actions may serve as indicators of impending clinical decline.

Purpose of the Study:

• To correlate clinical actions with clinical endpoints.
• To examine the relationship between clinical actions and deviating vital signs.
• To assess the predictive value of clinical actions for patient outcomes.

Main Methods:

• Prospective cohort study of patients on continuous vital sign monitoring.
• Analysis of clinical actions recorded in electronic medical records.
• Correlation analysis with patient outcomes, length of stay, and alarming monitoring minutes.

Main Results:

• 1529 patients included; 68 had negative clinical endpoints.
• Clinical actions correlated significantly with negative endpoints (p < 0.001) and length of stay (p < 0.001).
• Vital sign deviations correlated with clinical actions, especially in the 72 hours preceding an endpoint (p < 0.001).

Conclusions:

• Predefined clinical actions on general wards correlate with adverse outcomes and increased hospital stay.
• Clinical actions are associated with deviating vital signs, particularly before severe deterioration.
• Clinical actions show potential as intermediate measures for detecting patient deterioration.
