투약은 임상현장에서 전문적이고 책임감이 따르는 중요한 업무로 모든 간호사는 안전하고 효과적인 투약을 제공할 수 있어야 한다. 하지만 Institute of Medicine (IOM, 2006)의 보고에 따르면 미국에서 해마다 15,000여 개의 예방 가능한 투약위해사건(preventable adverse drug events)이 발생하여 환자들은 입원하는 동안 매일 한 개의 투약오류에 노출되고, 이로 인해 입원기간이 길어지며, 사망률 또한 증가하고 있다(Pirmohamed et al., 2004). 투약오류의 65-87%가 처방과 투여단계 동안에 발생하며 잘못된 약 혹은 잘못된 용량의 투여가 가장 흔한 유형이라 보고되었다(Tang, Sheu, Yu, Wei, & Chen, 2007). 이 중 과다 혹은 과소용량으로 투여되는 용량관련오류(Hicks, Becker, Krenzischeck, & Beyea, 2004)는 흔히 계산착오로 인해 발생하는 경우가 많으므로(Haw, Stubbs, & Dickens, 2007) 환자안전을 위해 간호사들은 적합한 약물계산역량을 갖추어야 한다.
Purpose: The objective of this study was to identify predictors of drug calculation competence of nursing students. Methods: A total of 120 students were recruited from 3 universities from November 10 to 20, 2011. The instruments for this study were drug calculation competence, self-efficacy for drug dosage calculation, anxiety for drug dosage calculation, and the academic self-efficacy scale. The data were analyzed by descriptive analysis, chi-square test, t-test, Scheffe test, partial correlation coefficients, and stepwise multiple regression using the SPSS 18.0 program. Results: The mean score of good competence group was 0.67±0.08 and the mean score of no-good competence group was 0.42±0.10. The drug calculation competence was positively related to self-efficacy for drug dosage calculation and academic self-efficacy scale, but negatively related to anxiety for drug dosage calculation after controlling personal attributes. The main predictors of drug calculation competence in nursing students were identified as anxiety for drug dosage calculation (β=-.25, p=.046), academic self-efficacy (β=.19, p=.035). These two factors explained about 10% of variance in drug calculation competence. Conclusion: Based on the results, the strategies reducing the anxiety for drug dosage calculation and improving the academic self-efficacy should be developed and implemented.
