- Use Additional Tools: Combine GCS with other assessment tools, such as the Pupil Reactivity Score or the Full Outline of UnResponsiveness (FOUR) Score. - Training and Practice: Regular training and practice can help reduce subjective variations in scoring. - Clear Documentation: Ensure clear and accurate documentation of all assessments to provide a comprehensive picture of the patient's condition. - Communicate Effectively: Use interpreters or alternative communication methods when language barriers exist.
