Searching for evidence Searching for evidence Presentation Transcript

  • “Library Elevenses” Search tips for those with a healthy appetite for knowledge. And cake.
  • Searching – the basics • Browsing/surfing – serendipity • Searching – plan ahead – Use PICO (Population or Patient; Intervention; Comparative intervention; Outcome) – Identify key concepts – Keywords/synonyms
  • PICO Clinical Question Search Strategy in CINAHL Patient/Problem Mechanically ventilated patients (MM "Ventilator Patients") OR (MM "Ventilation, Mechanical, Differentiated") OR (MM "Ventilators, Mechanical") OR (MM "Respiration, Artificial+") OR “mechanically ventilated” Intervention Mouthwash (MM "Mouthwashes+") OR mouthwash Comparison (if relevant) Toothbrushing (MM "Toothbrushing") OR (MM "Toothbrushes") OR “mouth care” Outcome Avoidance/reduction of Ventilator Associated Pneumonia (MM "Pneumonia, Ventilator- Associated") Type of Question Scoping question for possible change of procedure/practice Related articles; referenced articles; forward citation searching Type of Study Practice Guideline, RCTs, Meta-analysis, Case studies

  • Facebook Research Experimental evidence of massive-scale emotional contagion through social networks. Kramer AD, Guillory JE, Hancock JT. Proc Natl Acad Sci U S A. 2014 Jun 17;111(24):8788-90. doi: 10.1073/pnas.1320040111. Epub 2014 Jun 2. PMID: 2488960 Abstract Emotional states can be transferred to others via emotional contagion, leading people to experience the same emotions without their awareness. Emotional contagion is well established in laboratory experiments, with people transferring positive and negative emotions to others. Data from a large real-world social network, collected over a 20-y period suggests that longer-lasting moods (e.g., depression, happiness) can be transferred through networks [Fowler JH, Christakis NA (2008) BMJ 337:a2338], although the results are controversial. In an experiment with people who use Facebook, we test whether emotional contagion occurs outside of in-person interaction between individuals by reducing the amount of emotional content in the News Feed. When positive expressions were reduced, people produced fewer positive posts and more negative posts; when negative expressions were reduced, the opposite pattern occurred. These results indicate that emotions expressed by others on Facebook influence our own emotions, constituting experimental evidence for massive-scale contagion via social networks. This work also suggests that, in contrast to prevailing assumptions, in-person interaction and nonverbal cues are not strictly necessary for emotional contagion, and that the observation of others' positive experiences constitutes a positive experience for people.
