Abstract: Objective To understand the current nursing status of continuous renal replacement therapy (CRRT) in hospitals, and provide a reference for further improving the quality of specialized nursing. Methods A convenience sampling method was used. From August to December 2023, a self- designed questionnaire was used to investigate the nursing status of CRRT in 101 hospitals. Results A total of 115 questionnaires were distributed and 106 valid responses from 106 nursing units in 101 hospitals were collected, with an effective recovery rate of 92.17%. In terms of infection prevention and control management, 91 (85.85%) nursing units used disposable ready-made hemodialysis kits, 74 (69.81%) nursing units used disposable sterile rubber gloves for operations, 89 (83.96%) nursing units used ready-made replacement fluid, and 80 (75.47%) nursing units used disposable dedicated waste fluid collection bags. In terms of nursing operations, 57
(53.77%) nursing units directly connected the circuit after priming, 60 (56.6%) nursing units used a medical three-way stopcock to connect 5% sodium bicarbonate injection to the venous end of the extracorporeal circulation circuit during treatment, and 103 (97.17%) nursing units used closed blood return technology when disconnecting the machine. In terms of nursing management, 78 (73.58%) nursing units regularly conducted theoretical and operational assessments, 51 (48.11% ) nursing units have already carried out related in- hospital nursing consultations, and 36 (33.96%) nursing units have already used information-based specialized nursing record sheets. Conclusion There are several differences in the nursing care of CRRT among hospitals. It is recommended to further standardize and unify the clinical nursing standards for CRRT to promote the improvement of specialized nursing quality.
