75876-3

LOINC code 75876-3 identifies "Patient activity scale II [PASII]". The Patient Activity Scale II (PAS-II) questionnaire contains a combination of single measures from the Health Assessment Questionnaire II (HAQ-II) as well as the patient's assessment of pain in the past week and global assessment of pain (PtGA). The combined scores from these measures are used to derive the PAS-II total score [LOINC: 75841-7]. The PAS-II is calculated by multiplying the HAQ-II by 3.33 and then dividing the sum of the pain scale, PtGA and HAQ-II by 3. Assessment of disease activity for PAS-II may be defined as remission ≤0.25, minimal ≤3.7, moderate <8.0 and severe ≥8.0. The PAS [LOINC: 75877-1], a longer version, and PAS-II contain only patient derived data and are useful for the overall, continuous measure of rheumatoid arthritis (RA) disease activity.

This code measures Patient activity scale II in ^Patient. It belongs to the PANEL.SURVEY.PASII class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
