This document presents a sample Human Research Ethics Committee (HREC) application for a quantitative cross-sectional study investigating interventions used by healthcare workers in Australia to prevent needle stick injuries (NSIs). The project aims to assess healthcare workers' knowledge of NSI risk factors and evaluate current preventive measures, utilizing an online survey questionnaire distributed to 200 participants across two Melbourne hospitals. The research, led by Dr. Joanne Porter from the School of Nursing, Midwifery and Healthcare at Federation University, seeks to address the significant incidence of NSIs, aiming to identify the most effective interventions and contribute to the reduction of associated burdens. The study details the research aims, methodology, participant recruitment, data collection, and analysis methods, emphasizing the use of SPSS for statistical analysis. The study is designed to determine the interventions most frequently used by healthcare staff to prevent NSIs and compare it with current best practices to reduce the burden of such infection among the nursing workforce. The findings are expected to inform best practices and enhance reporting of such injuries among healthcare workers. The application adheres to ethical guidelines and includes detailed information about the project's objectives, significance, and relevance to current research, supported by relevant literature.
