Required graduate diploma in mental health nursing units
Specified units (40CP)
Project stream units (40CP)
Understanding evidence-based practice and research approaches is fundamental to health research. This unit provides opportunity for students who are health practitioners, to ask, acquire, interpret, analyse, synthesise, and integrate evidence to facilitate ongoing improvement in healthcare practice. Additionally, an understanding of the principles and philosophical positions underpinning different research approaches in health care is essential to critically evaluate research literature, and undertake health inquiry, workplace projects or health research. This will incorporate recognising, acknowledging and respecting culturally appropriate research approaches that include Aboriginal and Torres Strait Islander peoples and communities.
This unit addresses issues of evidence-based knowledge development and the methods and processes that health disciplines apply to health inquiry, project and research processes, within a person-centred care environment. Ways to evaluate solutions to complex clinical issues/problems in the health care environment and formulate a relevant question/topic are addressed. In addition, students will develop skills to search for, read and interpret relevant literature, along with approaches to analysis and synthesis of literature as a preparatory step in writing a literature review for a proposed health inquiry, workplace project or health research.
This unit aims to develop confidence and competence in the application of evidence-based practice and interpretation of health literature.
