APNA 27th Annual Conference Session 1031: October 9, 2013 Overview • Asking focused answerable questions Evidence Based Practice: • Conducting efficient searches Skills Boot Camp • Analyzing study methods • Determining how to implement evidence Joanne DeSanto Iennaco PhD, PMHNP ‐ BC Evidence Based Practice: Evidence Based Practice is : • “The conscientious, explicit and judicious use ‘The integration of best research of current best evidence in making decisions evidence with clinical expertise and about the care of individual patients . ” patient values .” (Sackett, DL, Rosenberg, WMC, Gray, JAM, Haynes, RB, Richardson, WS. Evidence based medicine: what it is and Sackett, DL, Straus, SE, Richardson, WS, Rosenberg, W., Haynes, RB. (2000). Evidence ‐ based medicine:How to practice and teach EBM. (p.1).

Asking a Focused Question… Steps in Evidence Based Practice 1. Identify a question (PICO) PICO • P = The Patient or Population 2. Find the best evidence to answer question “Who will be the focus?” 3. Critically appraise the evidence for validity, EX: In (patient, problem, risk factor) does… • I = Intervention or Clinical Action impact and applicability impact and applicability “What is the Exposure or the Treatment of interest?” 4. Integrate evidence with clinical expertise EX: does Treatment A compared to … • C = Comparison and patient values/wishes EX: Compared to Treatment B Reduce… 5. Evaluate process (prior steps) to improve • O = Outcome next time EX: Reduce Outcome of interest Iennaco 1

Searching the Literature Searching the Literature • Defining a Search Strategy – Database Choices What is the usefulness of an evidence based review if – References/Bibliographies we don’t find all the evidence out there? – Hand searching Hand searching – Contacting authors/researchers Will we ever find ‘ALL’ the evidence? – Conferences/Associations – Abstracts What if the evidence overwhelms us? • Dates to search • Savvy searching… What is the usefulness of an evidence based review if we don’t find all the evidence out there?
