Abstract
Overview: This article is the second in a new series on the systematic review from the Joanna Briggs Institute, an international collaborative supporting evidence-based practice in nursing, medicine, and allied health fields. The purpose of the series is to show nurses how to conduct a systematic review-one step at a time. This article details the process of articulating a review question to guide the search for relevant studies and discusses how to define inclusion criteria for the study-selection phase of the review.
