Chronic kidney disease patient safety in hemodialysis: evidence of scale validity and reliability

to analyze evidence of the validity and reliability of the Chronic Kidney Disease Patient Safety Assessment Scale in Hemodialysis Sessions (EASPRCH). a methodological study with an analysis of validity evidence (content and construct) and reliability (temporal stability, internal consistency, and parameterization). A total of 11 judges and 240 patients from three hemodialysis clinics participated. the EASPRCH consists of 15 items distributed across three domains: (1) Strategic Procedures for Error Prevention (6 items), (2) Organizational Processes in Health Management (5 items), and (3) Care Practices for Infection Control (4 items), with scoring available both by domain and overall. The scale has a maximum score of 45 points and a cutoff point (adequate/inadequate) of 34. It achieved a Cronbach's alpha of 0.78 and explained 72.41% of the total variance. the scale provides evidence of weaknesses or strengths related to specific indicators, which may or may not impact patient safety in hemodialysis care.
