Abstract
ContextSymptom burden is a strong predictor of reduced health-related quality of life and survival in patients with end-stage kidney disease. Renal supportive care (RSC) is a comprehensive approach shown to benefit symptoms in nondialysis conservatively managed patients, although its role in dialysis patients has not been reported. ObjectivesThis study aimed to investigate the impacts of RSC intervention on symptoms in dialysis patients. MethodsDialysis patients who were referred to an RSC clinic for symptom control between April 2010 and December 2017 were followed prospectively. Symptoms were scored using the Integrated Palliative care Outcomes Scale-Renal Inventory. Change in symptoms was analyzed at three visits and at final RSC visit within the study period. Correlation and linear regression were used to assess for effect modifiers. ResultsA total of 127 dialysis patients attended the RSC clinic for symptom management. Median age was 74 years, 62% males, median dialysis vintage was 2.2 years, and median-modified Charlson Comorbidity Index was 7. Mean combined physical and emotional symptom score at baseline was 17.5 (SD 9.6), the most overwhelming/severe symptoms being difficulty sleeping (35%), pain (31%), lack of energy (31%), poor mobility (24%), and itch (22%). Eighty patients had follow-up to at least three RSC visits (median 3.1 months). There was significant improvement in combined physical and emotional symptom score during three clinic visits (18.1 vs. 14.2; mean change −3.8; 95% CI −5.7 to −1.9; P < 0.001), with greatest improvement in symptom scores for the five most severe symptoms (each P < 0.001). Follow-up of these 80 patients to final RSC visit (median 13.0 months) showed sustained reduction in mean combined physical and emotional symptom score (18.1 vs. 14.4; mean change −3.7; 95% CI −5.6 to −1.7; P < 0.001). These changes occurred without change in dialysis delivery. ConclusionRSC intervention that focuses on symptom control and patient-centered care is associated with improved total and individual symptom burden in dialysis patients. This supports a role for RSC as a management adjunct in these patients.
