Nurses' knowledge of radiation protection: A cross-sectional study.

INTRODUCTION: Nursing roles are changing, as several countries have amended legislation so that nurses can make referrals for medical imaging examination that utilize ionising radiation. Nevertheless, nurses' radiation knowledge remains a poorly studied concept. The aim of the study was to characterize Finnish nurses' knowledge of radiation use and radiation safety. In this study, nurses were working in operating theaters, first aid clinics and cardiology laboratories. METHODS: A cross-sectional design was applied in which data were simultaneously collected from nurses working in eight hospitals. All nurses working in operating theaters, first aid clinics and cardiology laboratories (N = 1500) at the hospitals in Finland were invited to participate in the study. The response rate was 17% (n = 252). The employed Healthcare Professional Knowledge of Radiation Protection (HPKRP) scale included three areas of knowledge: radiation physics, biology and principles of radiation use; radiation protection; and guidelines of safe ionizing radiation use. Descriptive statistics and logistic regression analyses were used to identify factors that influence these three areas. RESULTS: Nurses reported high knowledge levels in radiation protection but low knowledge levels in radiation physics, biology and principles of radiation use. Moreover, nurses who had not received radiation education reported lower knowledges across all three areas than the nurses who had completed education. CONCLUSION: This study identified one major factor that significantly affects nurses' radiation knowledge, namely, having completed medical radiation education, as this factor positively influenced all three of the included areas of radiation knowledge factors. Therefore, healthcare organizations should concentrate on providing education to all nurses working with, or exposed to, radiation.

Development and validation of a psychometric scale for assessing healthcare professionals' knowledge in radiation protection.

INTRODUCTION: Healthcare professionals must sufficiently understand ionising radiation and the associated protection measures to avoid unnecessarily exposing patients and staff to ionising radiation. Hence, a proper safety culture is important to lowering health risks. The development and establishment of an instrument that can indicate healthcare professionals' understanding/knowledge of radiation protection concepts can greatly contribute to a good safety culture. The purpose of the present study was to develop and psychometrically test the Healthcare Professional Knowledge of Radiation Protection (HPKRP) self-evaluation scale, which was designed to measure the knowledge level of radiation protection by healthcare professionals working with ionising radiation in a clinical environment. METHODS: The presented research employed a cross-sectional study design. Data were collected from eight Finnish hospitals in 2017. A total of 252 eligible nurses responded to the newly developed HPKRP scale. The face and content validity were tested with the Content Validity Index (CVI). Explorative factor analysis was used to test construct validity, whereas reliability was tested with Cronbach's alpha. RESULTS: Overall S-CVI for the HPKRP scale was 0.83. Exploratory factor analysis revealed a three-factor model for the HcPCRP scale containing 33 items. The first factor was defined by Radiation physics and principles of radiation usage, the second factor by Radiation protection, and the third factor by Guidelines of safe ionising radiation usage. These three factors explained 72% of the total variance. Cronbach's alpha coefficient for the scale ranged from 0.93 to 0.96. CONCLUSION: The results provide strong evidence for the validity and reliability of the HPKRP scale. Additionally, educators can use the scale to evaluate healthcare students' understanding in radiation safety before and after education.
