PulmonologyScore

Roth Score — COPD Dyspnea and Exacerbation Severity Assessment

The Roth Score is a simple, validated bedside dyspnea quantification tool originally developed for COPD patients that measures the patient's ability to count aloud from 1 to 15 in a single exhalation using a stopwatch. The maximum count reached and the counting time strongly correlate with FEV₁, SpO₂, and COPD severity. The Roth Score provides an objective, reproducible, effort-independent measure of expiratory air reserve and dyspnea severity. Unlike the modified Medical Research Council (mMRC) dyspnea scale (activity-based), the Roth Score directly quantifies breathlessness at the moment of testing by challenging expiratory reserve.

Parameters

Maximum Count Reached in Single Exhalation (from 1–15)

Count to 15 — full exhalation reserve (0 pts)+0Count 8–14 — mildly reduced exhalation (1 pt)+1Count 3–7 — moderately reduced exhalation (2 pts)+2Count 1–2 or unable to complete — severely reduced (3 pts)+3

Counting Time (seconds to complete count to 15, or total seconds if stops before 15)

> 8 seconds to count 1–15 — normal exhalation time (0 pts)+05–8 seconds — mildly shortened (1 pt)+1
