Patient Acceptable Symptom State (PASS) in patients with primary Sjögren's syndrome in daily clinical practice.

Abstract

To explore Patient Acceptable Symptom State (PASS) in a standard of care cohort of patients with primary Sjögren's syndrome (pSS) and to compare patient characteristics including EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) between PASS and non-PASS groups. All pSS patients fulfilling ACR/EULAR classification criteria from the Registry of Sjögren's Syndrome LongiTudinal (RESULT) cohort, who had available PASS data at baseline were included. Patient-reported outcomes included the PASS question: "Considering all the different ways your disease is affecting you, if you were to stay in this state for the next few months, do you consider your current state satisfactory?"; yes: PASS / no: non-PASS. Of the 278 included pSS patients, 199 (72%) had an acceptable symptom state according to the PASS question, and median ESSPRI was 6 (IQR 4-7). In the PASS group, 118 (59%) patients had an unacceptable symptom state according to ESSPRI (score ≥5). In multivariable regression analyses, ESSPRI and disease duration were independently associated with presence of PASS. The accuracy of ESSPRI to predict PASS was fair (AUC of 0.78). The cut-off point of ESSPRI for presence of PASS with the highest Youden's index was 7.2 (sensitivity 85%, specificity 56%), followed by 5.2 (sensitivity 48%, specificity 90%). The majority of pSS patients reported being in an acceptable symptom state according to the PASS question, despite high ESSPRI scores. In our standard of care cohort, the optimal cut-off point of ESSPRI to predict PASS is different when focusing on sensitivity (±7) or specificity (±5).
