The BKAT is a valid and reliable test of basic knowledge in critical care nursing. Validity was established through a panel of nine experts in critical care nursing practice and education. Reliability was established at the alpha coefficient of 0.86 for the total test during the pilot study on a sample of 100 nurses working in CCUs . The BKAT , which is a 90-item test, has been used on both a supervised and an unsupervised basis. Findings from the pilot study included a statistically significant difference in basic knowledge between new graduates and nurses with 6 months to more than 5 years of experience in critical care nursing, and that the length of critical care experience is the best predictor of basic knowledge. No statistically significant differences were found in basic knowledge in the following groups of nurses: (1) ICU, SICU , and coronary care unit nurses, (2) those working in university or teaching hospitals, community hospitals, and government hospitals, and (3) nurses with an associate degree, diploma, or baccalaureate degree. The BKAT -2, a revision of the BKAT , indicates that the basic knowledge assessment tool can be updated as new technologies and new knowledge become part of the body of nursing knowledge related to safe practice in critical care nursing.
BKAT是一种有效且可靠的重症监护护理基础知识测试。其有效性由九位重症监护护理实践与教育领域的专家组成的小组确定。在对100名在重症监护病房工作的护士进行的预试验研究中，整个测试的信度通过0.86的阿尔法系数得以确立。BKAT是一项包含90道题目的测试，已在有监督和无监督的情况下使用。预试验研究的结果包括，新毕业护士与具有6个月至5年以上重症监护护理经验的护士在基础知识方面存在统计学上的显著差异，且重症监护护理经验的时长是基础知识的最佳预测指标。在以下几组护士的基础知识方面未发现统计学上的显著差异：（1）重症监护病房、外科重症监护病房和冠心病监护病房的护士；（2）在大学或教学医院、社区医院和政府医院工作的护士；（3）拥有副学士学位、文凭或学士学位的护士。BKAT -2是BKAT的修订版，表明随着新技术和新知识成为重症监护护理安全实践相关护理知识体系的一部分，基础知识评估工具可以得到更新。
