UpToDate
You should cite an UpToDate topic review as a chapter in a book titled UpToDate, edited by Ted Post, and published by UpToDate in Waltham, MA. Because our material is updated each year, you must always use the current year in your citation. There are no page numbers to cite. Below is an example of the correct format:
Marion DW. Pacing the diaphragm: Patient selection, evaluation, implantation, and complications. In: UpToDate, Post TW (Ed), UpToDate, Waltham, MA. (Accessed on January 04, 2018)
