Patients’ reporting of ADPKD symptom burden may differ from physicians’ impressions. In this quantitative, cross-section survey study, we evaluated patient and physician assessments of symptom burden at early- and late-stage ADPKD.Methods: In the United States, 300 patients with ADPKD and 155 physicians treating patients with ADPKD completed online surveys administered by Kantar. Disease stage was categorized as early (chronic kidney disease [CKD] stages 1– 3) or late (stages 4– 5). Patients completed the Work Productivity and Activity Impairment Questionnaire and reported current disease symptoms. Patients and physicians assessed impacts of ADPKD on daily life and burden of specific symptoms. Statistical analyses compared patient versus physician responses stratified by early- versus late-stage ADPKD.Results: We found that impairment in work productivity was statistically greater in late- versus early-stage CKD. Compared with physicians’ impressions, patients were more likely at early stages and less likely at later stages to report a moderate/strong impact of ADPKD on daily life. Among patients, 74% with early- and 88% with late-stage disease reported that ADPKD caused them to modify their daily lives. In early-stage disease, patients reported a statistically greater burden from feeling exhausted and less burden from dull kidney pain, cardiovascular problems, high blood pressure, and liver cysts than physicians assumed. At later stages, patients reported feeling exhausted and skeletal/joint pain as more burdensome, and frequent urination, high blood pressure, liver cysts, and hematuria as less burdensome, compared with physicians’ impressions.Conclusion: The results of this survey study demonstrate a disconnect between patients’ experiences and physicians’ awareness of the burden of ADPKD and highlight the need for more patient/physician discussion of symptoms and disease management.Keywords: autosomal dominant polycystic kidney disease, ADPKD, symptom burden, patient reports, physician views, survey
