  2. Prevalence of Chronic Pain: Systematic review Introduction to Medicine This systematic review is part of a research project for the Introduction to Medicine subject, of BiostatisticalService in the Medicine Faculty of Oporto University

  3. Prevalence of Chronic Pain: Systematic review • In this work we will focus: • Title and keywords • Abstract • Introduction • Participants • Methods • Results • Discussion • Website • Acknowledgements • References • Authors Introduction to Medicine

  4. Prevalence of Chronic Pain: Systematic review 1. Title and keywords Introduction to Medicine Prevalence of Chronic Pain in the General Population Keywords: Prevalence, Chronic pain, Systematic review, General population TOP

  5. Prevalence of Chronic Pain: Systematic review 2. Abstract • Objectives • quantify the Prevalence of Chronic Pain in the General Population; • relate chronic pain with other variables such as gender, age, geographical areas and anatomic regions; • describe the difficulties found during thework; • study the average duration of chronic pain. • Participants • All the articles that follow the inclusion criteria. Introduction to Medicine

  6. Prevalence of Chronic Pain: Systematic review • Method • query “chronic pain” AND prevalence; • www.pubmed.com and www.scopus.com; • Endnote (to manage references); • 1149 articles potentially could be included; • Screenphase and Inclusion phase; • 29 articles; • Extracting data; • Statistical treatment. • Results and Discussion/Conclusion • The results will be presented in the Abstract as well as the Discussion and the Conclusion. Introduction to Medicine TOP

  7. Prevalence of Chronic Pain: Systematic review 3. Introduction Introduction to Medicine • Chronic pain: definition • Pain definition: “(...)an unpleasant sensory and emotional experience associated with actual and potential tissue damage, or described in terms of such damage (...)” (IASP, 1986) • Chronic pain definition:“pain without apparent biological value that has persisted beyond the normal tissue healing time, usually taken to be 3 months” (IASP, 1986)

  8. Prevalence of Chronic Pain: Systematic review • Definition of pain and chronic pain – Associated Problems: • Incapacity in quantifying pain; • Subjective nature; • Contextualization; • No agreement about the necessary time to consider chronic pain (1 month, 3 months or 6 months beyond a normal recovery period); • Chronic pain duration. Introduction to Medicine

  9. Prevalence of Chronic Pain: Systematic review • Systematic review: definition • Planned review to answer a specific question and that uses systematic and explicit methods to identify, select and evaluate the studies; • It consists in reviewing all the existence references in medicine´s data bases: Scopus; Pubmed (for example). Introduction to Medicine TOP

  10. Prevalence of Chronic Pain: Systematic review • Relevance of the question and comments • Chronic pain: • Has an impact in patients’ quality of life, in family, health workers and institutions related to them and in society in general. Introduction to Medicine

  11. TOP Prevalence of Chronic Pain: Systematic review • Objectives • Quantify the prevalence of chronic pain in general population and relate it with geographical regions and other variables • Identify the most affected anatomical regions; • Describe the dificulties found when defining chronic pain; • Study the average time of chronic pain duration. Introduction to Medicine

  12. Prevalence of Chronic Pain: Systematic review 4. Participants Introduction to Medicine • Study design – systematic review • Selection criteria • Inclusion criteria: • Being a scientific article; • Focusing chronic pain (or its synonyms such as “continuous pain”, “delayed pain” and “intolerable pain”); • Cross-sectional studies (study of prevalence); • Studies with participants 18 years old or above;

  13. TOP Prevalence of Chronic Pain: Systematic review Introduction to Medicine • Exclusion criteria: • Studies focusing acute pain or other kind of pain; • Studies related to children/teenagers (<18); • Studies only comparing chronic pain with another type of pain; • Studies with animals; • Language not mastered.

  14. Prevalence of Chronic Pain: Systematic review 5. Methods • Search strategy in a systematic review: • Query Formulation: • Pubmed • Pain – 308765 • Pain AND prevalence – 27569 • Pain AND prevalence AND chronic - 3966 • “chronic pain” AND prevalence – 840 • Scopus • “chronic pain” AND prevalence – 536 • Endnote (References management software) • 1149 (287 repeated articles) Introduction to Medicine Total: 1376

  15. Prevalence of Chronic Pain: Systematic review • Articles selection • 1st phase or screenphase – reading the title and abstract of the obtained articles in the databases and exclusion of the ones that do not fit. • 5 random groups of 2 people; • 2nd phase or inclusion phase – according with the pre-established criteria of inclusion and exclusion, the fitting articles were chosen • the groups were maintained. Introduction to Medicine

  16. Prevalence of Chronic Pain: Systematic review Introduction to Medicine • Statistical methods • After the extraction of the article data, the articles’ information will be processed and analyzed with graphics and tables, based on statistical methods such as variable statistic description and forest-plots.
