Exploring the Readiness of Critical Care in Implementing Continuous Renal Replacement Therapy in Hail Hospitals, Saudi Arabia: Findings for Acute Kidney Injury Patient Care Improvement.

Continuous renal replacement therapy (CRRT) is a critical intervention for managing acute kidney injury (AKI) in critically ill patients. Critical care nurses (CCNs) play a pivotal role in its implementation, requiring adequate knowledge, a positive attitude, and practice proficiency. This study aimed to assess the levels and factors affecting CCNs' knowledge, attitudes, and practices (KAPs) regarding the care of patients receiving CRRT in Hail Hospitals, Saudi Arabia. A cross-sectional study was conducted with 190 registered CCNs from the critical care units of Hail Hospitals, Saudi Arabia, from March to May 2025. Data were collected using a sociodemographic characteristics sheet and the knowledge, attitudes, and practices questionnaire on CRRT. Non-parametric statistical tests (Mann-Whitney U, Kruskal-Wallis, and Spearman's correlation tests) were used to determine the relationships between variables. A multiple linear regression analysis was used to explore the factors affecting the study variables. The majority of CCNs had a high level of knowledge regarding CRRT management (66.3%), followed by moderate (21.1%) and low (16.6%) levels. Additionally, the majority had a high level of attitude regarding CRRT management (74.7%), followed by moderate (18.4%) and low (6.9%) levels. The majority of CCNs had a high level of practice regarding CRRT management (66.8%), followed by low (23.7%) and moderate (9.5%) levels. There was a significant positive correlation between CCNs' knowledge, attitudes (rs = 0.230, < 0.001), and practices (rs = 0.192, < 0.001). Additionally, there was a significant positive correlation between CCNs' attitudes and practices (r = 0.419, < 0.001). Multiple linear regression revealed a significant model (  <  0.001) when sociodemographic and work-related factors were analyzed as predictors of CCNs' levels of knowledge, attitudes, and practices regarding CRRT: Having more experience, working with a nurse-to-patient ratio of 1:2, and frequently using CVVHDF as a CRRT modality were significant factors for higher knowledge levels when compared to the reference categories. In addition, having a bachelor's degree and frequently using CVVHD, CVVHDF, or SCUF as a CRRT modality were significant factors for higher attitude levels regarding CRRT when compared to the reference categories. Having a bachelor's degree and frequently using CVVHD or CVVHDF as a CRRT modality were significant factors for higher practice levels regarding CRRT when compared to the reference categories. CCNs in Hail Hospitals self-reported high levels of knowledge, attitudes, and practices regarding CRRT management, followed by moderate levels. Targeted educational programs, standardized protocols, and organizational support are recommended to improve CCN care for CRRT and to optimize patient outcomes.
