1. While the nurse might learn a great deal from this search, the number of "hits" on a general search engine would be daunting. It is also not likely that all of the information retrieved would be scientifically- or evidence-based. Identifying the evidence-based recommendations would be very time consuming.
2. In order to read enough information, the nurse would have to search the journals for appropriate articles and then find the journals, either in print or online full text. This would be a time-consuming endeavor.
3. Sites such as Joanna Briggs have already reviewed the evidence and have used the hierarchy of evidence levels to categorize the information. This would be the quickest method to find reputable evidence.
4. The information on the WHO site is not only for healthcare professionals, but is also for the general public. It is likely that very good information is available, but locating it in this huge site might be time consuming.
