CHARACTERISTICS OF KNOWLEDGE AND PRACTICE IN MEASURING ANKLE –BRACHIAL INDEX AMONG INTENSIVE CARE UNIT NURSES
Main Article Content
Abstract
Background: Sequential Compression Devices (SCD) help prevent deep vein thrombosis when anticoagulants are contraindicated, especially in intensive care unit (ICU) patients. The technique of measuring Ankle Brachial Index (ABI) is used to screen for lower limb peripheral artery disease and adjust the pressure settings to reduce the risk of complications related to SCD. ABI measurement is a necessary skill for ICU nurses. Objective: To assess the knowledge and practice of ABI measurement among ICU nurses. Method: A descriptive cross-sectional study was conducted on 42 ICU nurses at University Medical Center Ho Chi Minh City. A set of questions validated by an expert panel was used to assess the knowledge and practice of ABI measurement. Results: The set of 20 questions had I-CVI ranging from 0.88 to 0.986; S-CVI/Ave from 0.85 to 0.94; and S-CVI/UA from 0.71 to 0.95. The percentage of nurses who had been trained in ABI measurement and had practiced measuring ABI were 52.4% and 32.7%, respectively. After assessment, 33.3% of nurses achieved a passing score. The overall score was 12.21 ± 0.91, with knowledge scores at 4.36 ± 0.93 and practice scores at 7.86 ± 0.84. Conclusions: ICU nurses' knowledge and practice of ABI measurement are not optimal. Effective training programs are needed to improve ABI measurement competency.
