Background: Coronary angiography is an invasive procedure used to diagnose coronary artery disease, and standard nursing care before, during, and after this procedure. A comparison of the current care with the existing standards can lead to improved nursing care quality, increased patient safety, and reduced medical costs. Objectives: Therefore, the aim of this study was to audit the nursing care provided before angiography. Methods: In this analytical descriptive study, the nursing care provided to 400 patients undergoing coronary angiography was evaluated using the event-based sampling method in the angiography ward of hospitals aﬃ liated to Shahrekord University of Medical Sciences. Data were collected by a demographic form and a standard nursing care checklist. Data were analyzed using descriptive statistics (i. e., frequency, mean, and standard deviation) and analytical statistics (i. e., chi-square, independent t-test and analysis of variance) in SPSS 18 version. Results: Before angiography, nursing care compliance score was 51. 63 4. 21, which was signiﬁ cantly diﬀ erent than the normal value (normal score: 61-81). At the preoperative stage, 25 (6. 3%), 374 (93. 5%), and 1 (3%) caring cases, the standard of nursing care was poor, moderate, and good, respectively. Conclusions: Based on our results, in one case, the provided nursing care was in accordance with the standard of nursing care at the preoperative stage of angiography, which can be attributed to the lack of education, control, facilities and awareness among nurses about the importance of standard care.
