Sufficiency of Knowledge Processed in Patient Education in Dialysis Care

PURPOSE: Patient education improves health and treatment adherence of patients with chronic kidney disease. However, evidence about the sufficiency of patients’ knowledge processed in patient education is limited. The purpose of this study was to evaluate subjective and objective sufficiency of knowledge processed in patient education in dialysis care and treatment. PATIENTS AND METHODS: A cross-sectional study design was used. The sample (n=162) comprised patients in predialysis or home dialysis. All eligible patients during the data collection timeframe (2016–2017) in two university hospital districts in Finland were invited to participate. Subjective sufficiency was evaluated with a structured questionnaire having 34 items divided into six dimensions of empowering knowledge (bio-physiological, functional, social, experiential, ethical, and financial) on a Likert scale (1=not sufficient at all, 4=very sufficient). Objective sufficiency was evaluated with a structured knowledge test with 10 items (score range 0–10, correct=1, wrong/no knowledge=0) based on the multidimensional content of patient education emphasizing bio-physiological dimension. RESULTS: In subjective sufficiency of knowledge, the mean was 3.27 (SD 0.54). The bio-physiological dimension of empowering knowledge was the most sufficient (mean 3.52, SD 0.49) and the experiential the least (mean 2.8, SD 0.88). In objective sufficiency, the means ranged 5.15–5.97 (SD 2.37–2.68) among patients in different modalities of dialysis care and treatment. The least sufficient objective scores were bio-physiological and functional knowledge. The subjective and objective sufficiency did not correlate with each other. CONCLUSION: Patients’ knowledge, either subjective or objective, does not seem to be sufficient. Hence, attention should be paid to supporting patients with more personalized knowledge. Furthermore, the relationship between subjective and objective sufficiency needs future consideration, as their non-correspondence was a new discovery.
