ABSTRACT
The paper reports a review on the current situation of the hierarchy and quality of the evidence related to both national and international evidence-based nursing research and practice.The limitations and barriers have been analyzed from both research methodology and data acquisition technique aspects.The available evidences provided by past studies are limited in post hoc indicators (e.g.hospital stay,fatigue,stress or sleep quality,etc.) and subjective methodologies (e.g.questionnaire,self-report or interview,etc.),that restrains the further development of evidence-based healthcare,in terms of its reliability,validity and application.The advantages/disadvantages and feasibility of new potential technologies,such as body sensors and smart phones,have also been discussed.
