A conceptual framework to improve the quality of life in patients with CKD on dialysis in KwaZulu Natal Province, South Africa

Abstract

Chronic kidney disease (CKD) is one non-communicable disease mainly caused by comorbid of diabetes and hypertension, thus compromising quality of life for the patients. Few rigorous Quality of Life frameworks on chronic kidney disease (CKD) have been reported in low-middle income countries including South Africa. Therefore, the study aimed at developing a Conceptual Framework to improve the Quality of Life in Patients with CKD on Dialysis in KwaZulu Natal Province, South Africa. A Mixed method sequential explanatory design which entails collection of quantitative data, followed by qualitative. A purposive sampling of 316 CKD patients for quantitative was initially selected. For qualitative, 17 healthcare professionals were theoretically sampled until data saturation. A structured questionnaire (WHO HRQOL–BREF) was utilized to collect numerical data for quantitative phase, while focus group discussions provided qualitative insights. The quantitative results indicated low quality of life (QoL) in several dimensions: economic (98 %), psychological (95 %), physical (70 %), and social (55 %). Grounded theory analysis of the qualitative data identified key predictors of QoL as the patients' geographic location, accessibility to haemodialysis centres, their ability to adapt and accept the condition, self-management practices, support from family members and caregivers including the presence of well-trained nursing staff.A comprehensive conceptual framework was developed through identifying contextual factors, interventions and outcomes that is expected to improve the QOL. The study recommends the immediate intervention of the policy makers and health care providers in drafting and implementing policies to improve the QOL in patients with CKD.
