Editor's Notes
- In the first part, I will discuss what a systematic literature searches is and why we conduct them. Then I will show you how to develop search strategies and conduct searches. We will look at some examples to learn how to do this in practice. At the end of the day, we will develop the search strategy, conduct the search and collect results for the Bach Flower Remedy.
- What: a systematic approach to search for literature Why: minimize bias Should be: thorough, objective and reproducible How: often conducted in several phases, using various sources
- The, what I would call, main three databases that we search are PubMed, Cochrane, and EMBASE. Access to PubMed free and it contains Medline citations. (Medical Literature Analysis and Retrieval System Online) is the U.S. National Library of Medicine's premier bibliographic database that contains over 16 million references to journal articles in life sciences with a concentration on biomedicine. In some cases, specialized databases should be searched. For example, if the question deals with a drug intervention, a pharmaceutical database should be searched. Since our topic, Bach Flower Remedies, falls within complementary medicine, we will also search AMED.
- Two phases of the literature search which will not be addressed today are the grey literature search and the manual literature search. The grey literature search is a search for publications not published commercially or indexed by major databases. The manual search is the final phase of the literature search. In the 4. session I will come back to the manual search.
- If necessary, the concepts included in the question should be discussed with reviewers.

- Begin either with a clinical question and use it to form a PICOTS question or begin with a PICOTS question. The PICOTS structure is especially suitable to the literature search because it identifies the main concepts and indicates how the concepts are related. ---HANDOUT----

- * Zahnfleisch The terms are read from left to right. Do NOT use NOT in a systematic review!!
- Again, terms are read from left to right.
- Some special characters vary from database to database. Take care with Latin roots (e.g. pharma). American / British spelling. Hypens not readable in EMBASE. Use OR for pluralization.
