  • Nursing school focuses on little research
    • Wasn’t until Master that you really learn what to look for and what is good research
    • Assumed all evidence based practice is done the same
      • Every hosptial does it differently
      • All research is not the same
  • What infulences research?
    • Has to be accepted to be published
    • First author came up to study the subject
    • Impact factor
  • Publication bias
    • Reasearch is done based on needs
    • What subject can get me published?
    • Journals more likely to accept research where findings match the hypothisis
      • Positive results
      • Journals are filled with more positve results
    • This lays groundwork for bias
      • See more of something we think that is representaive of the population
    • We have to look for the big picture in research
    • Publication bias results from the selective publication of studies based on the direction and magnitude of their results-studies without statistical significance (negative studies) are less likely to be published.
    • We need those negative results also
  • The file drawer problem
    • suggests that results not supporting the hypotheses of researchers often go no further than the researchers’ file drawers, leading to a bias in published research
  • P-hacking
    • Doing the same tests over and over until you eventually hit the desired results by chance.
    • P-hacking is typically done through manipulation of “researcher degrees of freedom,” or the decisions made by the investigator.
    • There is no indication that p-hacking was used
  • HARKing
    • HARKing is defined as presenting a post hoc hypothesis in one’s research report as if it were, in fact, an a pre hypotheses.
  • Citation Bias
    • The more times your article has been cited, the more value we place on it
    • We cite positive results more often
    • Feeding on itself problem
  • How are we combating publication bias?
    • Publication bias may be reduced by journals publishing high-quality studies regardless of novelty or unexciting results, and by publishing protocols or full-study data sets
    • There are grassroots orginizations publishing high quality studies regarless of results
