The literature review was conducted in the following manner:
- A search of Deakin University's library journal databases was conducted for journal articles. The searches were restricted to refereed journal articles as the database possessed that limiting capability.
- A review of publications held in the Deakin University library for references on community needle and syringe disposal issues.
- Personal communication was made to various personnel who have demonstrated expertise/experience in community needle and syringe disposal issues to ascertain their understanding of the latest literature on this topic.
- Current and best-practice disposal of N&S.
- Community concerns in relation to discarded N&S in public areas.
- Issues and barriers for disposal of N&S.
- Hazards associated with disposal of N&S.
It should also be noted that several articles reviewed provided an overview analysis of existing literature – as most of these were published in peer review journals, the conclusions contained within were accepted.
Several publications referred to the term "sharp", rather than N&S. When this has been done, the original term is used. NSP was also referred to as needle exchange programs, in these instances the term NSP has been used.
