Objective:To form an evidence-based practice standard for early ambulation after radiofrequency catheter ablation via femoral artery (RFCA) , so as to improve the awareness of nurses' evidence and the rate of clinical practice standards, and reduce the incidence of patient complications.Methods:Totals of 2 evidence summaries, 4 systematic reviews and 2 guidelines were included through searching domestic and foreign databases. The innovation-Promoting Action on Research Implementation in Health Services (i-PARIHS) was used to analyze the obstacles to the application of evidence and formulate available solutions. From June 2019 to November 2020, convenience sampling was used to select 180 patients who underwent RFCA and 39 nurses in the Department of Cardiovascular of the Affiliated Hospital of Qingdao University for evidence-based.Results:A standardized procedure and evaluation record form for the guidance of ambulation after RFCA were formed, and the nursing norms after RFCA were updated. After 2 rounds of evidence application, the awareness and implementation rates of the nurses' review indicators increased, and the differences were statistically significant ( P<0.01) . After 2 rounds of evidence application, the patients' low back pain score and anxiety score were lower than those before the evidence application, and the differences were statistically significant ( P<0.01) . The incidence of dysuria and the vagus nerve firing in patients were lower than those before the evidence application, and the differences were statistically significant ( P<0.05) . Conclusions:The development of this evidence-based project promotes early postoperative ambulation of patients and reduces the incidence of complications.

Objective:To establish an evidence-based nursing practice standard for subcutaneous injection of low-molecular-weight heparin in inpatients so as to improve the evidence awareness of nurses and the standard rate of clinical practice and reduce the incidence of adverse reactions in patients.Methods:From June 2018 to June 2019, we analyzed the obstacle to evidence application and formulated available solutions according to the standard procedure of evidence-based continuous quality improvement and by combining promotion framework (i-PARIHS) . We selected 44 nurses and 80 patients of Department of Cardiovascular Medicine at a general Class Ⅲ Grade A hospital in Qingdao as the research object to carry out quality review and effect evaluation before evidence application, in the first round and the second round after evidence application.Results:In the second round of review after evidence application, the awareness and implementation rate were significantly improved, and the incidence of ecchymosis, induration, bleeding and the VAS score were significantly reduced with statistical differences ( P<0.05) . The department related work process was improved, and the evidence-based nursing practice standard for subcutaneous injection of low-molecular-weight heparin in inpatients was formed. Conclusions:The clinical development of the evidence-based project can standardize nurses' operation behavior of subcutaneous injection of low molecular weight heparin and reduce the incidence of adverse reactions in patients.
