The Correlation Between Symptom Clusters and Quality of Life in Patients with Systemic Lupus Erythematosus: A Cross-Sectional Study.

BACKGROUND

Systemic lupus erythematosus (SLE) is characterized by a range of symptoms that often cluster together, impacting the quality of life (QoL) of affected individuals.

OBJECTIVE

To delineate the composition of symptom clusters in patients with SLE and analyze their correlation with QoL, thus providing a basis for symptom management.

METHODS

Using convenience sampling, 201 patients were recruited. Data were collected using a general information questionnaire, SLE Symptom Checklist and Lupus Quality of Life scale. Symptom clusters were identified using exploratory factor analysis, and their correlations with QoL were analyzed using Spearman correlation analysis.

RESULTS

The most common symptom among patients was fatigue (64.7%). Five symptom clusters were identified: fatigue-related symptoms, weight gain-related symptoms, itch-pain-related symptoms, skin change symptoms, and body image symptoms. Fatigue-related, weight gain-related, and body image symptom clusters showed significant negative correlations with overall QoL scores and scores in various dimensions (P < .05). The itch-pain symptom cluster was negatively correlated with the total score of QoL and several dimensions such as pain status, burden status, mental health status, physical health status, and fatigue status (P < .05). The skin change symptom cluster was negatively correlated with the total score of QoL and several dimensions, such as mental health, physical health, and fatigue status (P < .05).

CONCLUSION

Patients with SLE exhibit significant symptom clusters correlating with overall QoL. Such data highlight the need for nurses to evaluate symptom clusters and intervene in related factors, enhancing QoL.
