An audit of a patient-at-risk trigger scoring system for identifying seriously ill ward patients

Area of Science:

• Critical Care Medicine
• Health Services Research

Background:

• Early identification of patients at risk of critical illness is crucial for timely intervention.
• Existing early warning systems require validation for effectiveness and clinical utility.

Purpose of the Study:

• To evaluate the Lewisham patient-at-risk trigger scoring system (PAR-T) as an early identification tool for critical illness.
• To assess the benefit of the PAR-T flowchart protocol and patient outcomes.
• To explore illness severity, management of chronically ill patients, and organizational factors.

Main Methods:

• A prospective trial of the PAR-T system was conducted across five acute ward areas.
• Data collection focused on the scoring system's effectiveness, protocol adherence, and patient outcomes.
• An audit approach was used to explore various aspects of patient management and organizational issues.

Main Results:

• The PAR-T scoring system demonstrated sensitivity in identifying patients at risk of critical illness.
• The audit provided insights into illness severity and management strategies within different patient groups.

Conclusions:

• The PAR-T system is a sensitive tool for early identification of critical illness.
• Wider implementation is recommended to further analyze PAR-T's sensitivity and specificity.
• Further research should focus on identifying the most sensitive markers for critical illness.
