Established, well validated, prognostic clinical-medical parameter for risk stratification of a patient with dyspnea. The ATS score is a symptom-based classification and divides dyspnea into five grades (0 to 4) depending on the symptoms and the degree of severity of various characteristics:
- Grade 0: No dyspnoea. No shortness of breath - except during significant physical exertion.
- Grade 1: Mild dyspnoea. Shortness of breath when walking rapidly or slightly increasing.
- Grade 2: Moderate dyspnoea. Shortness of breath when walking normally on the flat, pauses to catch your breath even at your own pace.
- Grade 3: Severe dyspnea. Pauses when walking after a few minutes or after about 100 metres at walking pace.
- Grade 4: Very severe dyspnea. Too short of breath to leave the house. Shortness of breath when talking and/or dressing.
The aim is to predict lethality or to predict risk (identification of patients with a low risk of lethality who can be safely treated on an outpatient basis or those who require more intensive monitoring and therapy in the clinic).
Modified ATS-Score for the assessment of intensive care treatment:
- Necessity of intubation and machine ventilation
- Need to administer vasopressors > 4 hours (septic shock)
- severe acute respiratory insufficiency (paO2 / FiO2 <250)
- multilobular infiltrates in the ro- thorax
- systolic blood pressure < 90 mmHg
- disturbed consciousness
- respiratory frequency > 30/min
- acute renal failure
If at least 1 major criterion or 2 minor criteria are positive, immediate intensive medical treatment is recommended. The sensitivity of the ATS score is 69%, the specificity 97%, the predictive value 94%.
