Life is full of ”truths” In clinical science, many of themareuntrue. The question is, howcanyouquickly and efficientlyuncover the truth?
Prevalence of low back painaccording to the literature The prevalence rates in the Nordic literaturerangedbetween 3% and 79%. Theycannot all have been right!
Readingarticles is Time consuming Not fun Oftenconfusing – youcannottake in all the details AND whenyoureadarticle #2 youforgetwhatwasimportant in article #1
An efficientmethod is the criticalsystematicliteraturereview The process is boring But whenyou have assembled all information it becomes FUN because, if done correctly, all relevant information is easilyaccessible and andthere is noneed to rememberanything
The idea Get all relevant information Createthreecheck-lists Look for information in the articleswithhelp of the check-lists Trust onlyquality information Gives you an overview New publicationscan just beadded to the oldchecklistwith minimum effort
Afterwards Read and enjoyonly the highqualityarticles! If youread the poorqualityarticles, youwillsuddenlyseehowuntrustworthytheyare!
1. Get all relevant information Decidewhatyouneed Speak to a librarian Set up a searchstrategy (searchmachines, search terms, language, years) See whatyouget and do it again, but better Throwawayorkeep? Order/download the relevant stuff Bewellorganized and methodical
2. Createthreechecklists Description of study Quality of research method Results
Items in thesechecklists Descriptive items to seeif the various studies arecomparable (and relevant to yourneeds) Quality items are all thoseaspectsneeded in yourdiscipline to ensure a truthfulresult (e.g. absence of various types of bias and valid outcomesmeasures) Resultscanbe multiple and confusing. Boil it down to what is relevant for you and try to usecomparableaspects
3. Read it criticallybut only the methodsection However, do not read the article, look for relevant information Start with the description of study and quality of research methods Search for textbelonging to eachchecklist item this is quick (method and sometimesresultsections) Note whether info thereor not be brief
Using the checklists Filling in data for the checklist is a bit tedious but fairlyquick The poorer the quality of the study the more difficult to find the check list information in the text Interpreting the checklistwhencompleted is: Quick Easy Fun
Trust onlyquality information Set up yourownpre hoc criteria for ”relevant” articles and for ”sufficientlyhigh” quality Irrelevant orpoorquality studies – disregard Mediocre studies – distrust Good studies probably rare – trust
