Fatigue Severity Scale

Assign the FSS, collect patient responses, score, and review in one clinic workspace.

What is the FSS?

The Fatigue Severity Scale (FSS) is a widely used psychometric assessment in sleep clinical practice. Clinics use it to collect structured patient responses that support clinical review and documentation.

Who uses the FSS?

Clinicians in sleep settings use the FSS as part of intake, assessment, and outcome monitoring workflows. It provides structured evidence to support clinical judgement.

Why send the FSS through Lirena?

  • Assign from the client profile in seconds
  • Send a patient-friendly completion link
  • Receive deterministic scoring output
  • Keep response detail attached to the record
  • Export for documentation or downstream systems

What does a reviewed FSS record look like in Lirena?

After the patient completes the FSS, Lirena returns scored responses to the client profile. Clinicians can review item-level responses, check the score summary, add notes, and export the record.
