However, the relationship between family members' delirium knowledge and their satisfaction with ICU care remains understudied. This study investigated the association between ICU patients' relatives' delirium knowledge levels and their care satisfaction, while identifying key predictors of family satisfaction. Materials and Methods: This cross-sectional study was conducted between January and April 2024 at Turgut Ozal Medical Center, Malatya, T & uuml;rkiye. The study included 305 family members of ICU patients hospitalized for >= 48 hours. Participants were recruited using convenience sampling from four ICUs (internal medicine, coronary, neurology, and medical oncology). Data collection instruments included: Caregiver Characteristics Form, Caregiver Intensive Care Delirium Knowledge Questionnaire-Turkish Version (CIDKQ-T), and Family Satisfaction in the Intensive Care Unit scale (FS-ICU-24). Statistical analyses included descriptive statistics, Pearson correlation coefficient/Spearman's rank correlation, and multiple linear regression. Results: Participants demonstrated moderate delirium knowledge (CIDKQ-T mean: 11.62 +/- 2.54, range: 0-21) and moderate ICU care satisfaction (FS-ICU-24 mean: 52.14 +/- 14.48, range: 0-100). Strong positive correlations were found between delirium knowledge and all FS-ICU-24 dimensions: total satisfaction (r=0.60, p<0.001), care satisfaction (r=0.45, p<0.001), decision-making satisfaction (r=0.53, p<0.001), and information satisfaction (r=0.48, p<0.001). Multiple regression analysis (R-2=0.36, F (7.142) = 12.85, p<0.001) identified delirium knowledge as the strongest predictor of family satisfaction (beta=0.42, p<0.001), followed by university education (beta=0.31, p=0.002), presence of neurological disease (beta=0.28, p=0.004), and female gender (beta=0.25, p=0.008). Longer hospitalization (10-13 days) negatively affected satisfaction (beta=-0.22, p=0.018). Conclusion: Family members' delirium knowledge significantly predicts their ICU care satisfaction, explaining 36% of the variance in satisfaction scores. These findings support implementing structured delirium education programs for families as part of family-centered ICU care protocols.eninfo:eu-repo/semantics/openAccessDelirium KnowledgeIntensive Care UnitFamily SatisfactionPatient RelativesArticle10.4274/eajem.galenos.2025.847702514552WOS:001683503900001Q4
