Supplementary Material for: Patient and caregiver perspectives on gender disparity in chronic kidney disease: Questionnaire survey, based on an interview study

Background: Chronic kidney disease (CKD) in stages 3-5 without albuminuria occurs more often in women than in men; however, most patients initiating and receiving kidney replacement therapy (KRT) are men. Sex-determined biological factors and gender-related aspects likely both account for this discrepancy. Patient opinions on gender-related discrepancies in kidney care have not been investigated.
Methods: Building upon the findings of semi-structured interviews previously conducted with CKD patients and their caregivers, two questionnaires were developed to investigate patient behavior and opinions relating to gender and CKD. These questionnaires containing 39 items were distributed to eight outpatient clinics in Austria. Responses were descriptively analyzed and compared between genders, as well as between age groups and CKD stages.
Results: Questionnaires from 783 patients and 98 caregivers were included in the analysis and covered health awareness and self-management of disease, the impact of gender roles and gender equality, and patient autonomy and trust in the health-care system. 56.1% of men patients and 63.1% of women patients found that women were better at looking after their health compared to men (41.1%/34.3% no difference, 2.8%/2.6% men better). 95.4% of men patients, 95.0% of women patients, 100% of men caregivers and 95.5% of women caregivers stated that all patients with kidney disease were treated completely equally, irrespective of gender.
Conclusion: Neither the patients nor the caregivers stated gender-determined treatment decisions in CKD care. Both men and women however agreed that women are better at maintaining their own health and excel in disease self-management.
