If you took a look at the RETREAT framework on the previous page you will have noted there are a number of things required to successfully complete a review. Researchers often under estimate the time and resources required. You will need at least one other reviewer to screen through all of the papers. You will need access to a reference management system such as Endnote. If you are undertaking a meta analysis you will also need to contact a biostatistician.
Both Cochrane and JBI recommend the addition of a librarian to the review team. Check out this article on the contribution of the librarian to a review team.

Considerations:
Methodological guidelines require that multiple reviewers are involved during all stages of a review.
It is not rigorous enough to single review the papers at the title/abstract screening stage, or to use a sampling approach to quality control.
If you are under a short or tight timeline you could consider doing a rapid review instead.

Considerations:
Developing a review protocol can:
Help avoid duplication of research
Help to clarify the SR process and its steps
Aid clear establishment of the inclusion and exclusion criteria
Can also be published - a small number of journals will publish protocol papers

Considerations:
How many papers do I need? This is a common question from researchers, and there is no definite answer.
However as a very general guide you would be hoping for more than 4 papers in the final analysis (personal opinion). Officially however you do not need any included studies to publish a review.
