Competence is defined as a combination of an individual's knowledge, attitude, and skills. Nurses, as the primary caregivers to hemodialysis patients, have an essential role in achieving hemodialysis adequacy. Hemodialysis adequacy achievement is one of the quality indicators of hemodialysis care. The research aims to identify the relationship between nurse competence and the achievement of hemodialysis in Bandung. The research design was correlation analytical with a cross-sectional method, which involved 82 hemodialysis nurses and 82 hemodialysis patients. Samples were using consecutive sampling. The data were analyzed using chi-square. The result shows that nurse's competence, especially nurse's attitude and skills in providing nursing care for hemodialysis patients, has a significant relationship with the achievement of hemodialysis adequacy. Nurses in the hemodialysis unit should improve their knowledge, attitude, and skills in providing nursing care. © 2021 Elsevier España, S.L.U.
