2. Developing a Protocol

3. Objectives: • Describe the format of a Cochrane Protocol • Identify new projects for the Cochrane Library • Explain the process of registration of a title • Outline the process of protocol writing Alhashimi

4. Review Manager (RevMan) • The software is designed to help authors construct reviews in the appropriate format and to prepare files required to transfer reviews electronically. • It helps authors record changes done Alhashimi

5. Each protocol consists of: • a cover sheet – giving the title, citation details and contact addresses • the text of the protocol – consisting of an introduction (background and objective), methods (selection criteria,  search methods, data collection and data analysis), acknowledgements and conflicts of interest • tables and figures - relevant to the background or methods • references Alhashimi

6. The text of a protocol ends just before the results sections. The results sections begin with a description of the studies identified by the review, which should start with a summary of the inclusion/exclusion of studies. Alhashimi

7. Planning a review- writing the protocol

8. Steps 1: Formulating A Good Question Step 2: Identification of Relevance of Review Planning the Review Step 3: Registering Title Step 4: Writing the Protocol Alhashimi

9. Step 1: Formulating A Good Question • Clinical Relevance • Prevalence; duration • Severity • Cost to individuals, society • Ability to influence practice • Feasibility of assessment • Intervention • Interest and motivation of reviewers • Ethical, political and social consideration Alhashimi

10. Formulating A Good Question • Formulate the research question in PICO format • P Population and medical problem to be investigated • I Intervention • C Comparator or Control • O Outcomes of interest Alhashimi

11. Steps 1: Formulating A Good Question Step 2: Identification of Relevance of Review Planning the Review Step 3: Registering Title Step 4: Writing the Protocol Alhashimi

12. Step 2: Identification of Relevance of the Review • To avoid unnecessary duplication of effort • Search for completed and ongoing reviews by contacting relevant review group. • New review required in the absence of a suitable review. Alhashimi

13. Potential authors adviced on availability of review titles by respective CRG • Uncovered tiltles and priority topics • Occasionally updating/expanding an existing review is required • Titles preferably relevant to the authors region and will help to influence healthcare practice Alhashimi

14. Steps 1: Formulating A Good Question Step 2: Identification of Relevance of Review Planning the Review Step 3: Registering Title Step 4: Writing the Protocol Alhashimi

15. Registering a title • The first step in the review process is to agree a review topic with the relevant Collaborative Review Group (CRG). • A title will be registered, possibly after discussion among the CRG editors, and the review authors will be invited to submit a protocol. • While questions should be posed in the protocol before initiating the full review, these questions should not become a straightjacket that prevents exploration of unexpected issues Alhashimi

16. Registering Title • The title of the prospective systematic review is registered online in the Cochrane Library • Authors details and contact numbers included • Can be edited before the final publication of the review. Alhashimi

17. Steps 1: Formulating A Good Question Step 2: Identification of Relevance of Review Planning the Review Step 3: Registering Title Step 4: Writing the Protocol Alhashimi

18. Step 4: Writing the Protocol • Takes as much time as you can put in it but no longer than 3 months • Protocol is a written in a clear and precise method • RevMan ( Review Manager ) : the Cochrane Collaboration’s review management software Alhashimi

19. Step 4: Writing the Protocol (cont) • Background first – takes the longest • Protocol will be imported on the RevMan format and sent to the relevant Review Group who will send it to internal and external peer reviewers who will in turn send their comments. • Accept/reject with justifications • An accepted version will be edited and sent for publication. • You will have 12 months time to write the systematic review. Alhashimi

20. Background • Description of the condition • Description of the intervention • How the intervention might work • Why it is important to do this review Alhashimi

21. Writing the Systematic Review

22. Establishing a • Search Strategy Writing the Systematic review Identification of relevant trials Description of Studies included in the review Description of Studies excluded from the review Alhashimi

23. Step 5: Writing the Systematic Review • Establishing a Search Strategy • Identification of relevant trials • Description of Studies included in the review • Description of Studies excluded from the review Alhashimi

24. Search Strategy • Construction of a search strategy should be based on the components of the research question, population and intervention • Searches are run on Cochrane Trial Register, MEDLINE (from 1966 onwards), EMBASE (from 1974 onwards), CINAHL ( Cumulative Index to Nursing and Allied Health Literature), PsycInfo (from 1967 onwards) • Handsearching to identify very recent publications or those not included on the electronic datbases Alhashimi

25. Step 5: Writing the Systematic Review (cont) • Data Extraction/ Collection • Data Analysis • Methodological quality of included studies • Results • Discussion • Reviewers’ Conclusion • Implication for practice • Implication for research Alhashimi

26. Data Extraction/ Collection Data Analysis Methodological quality of included studies Writing the Systematic Review (cont) Results Discussion • Reviewers’ Conclusion • Implication for practice • Implication for research Alhashimi

27. Methodological Quality Of Included Studies • This is the degree to which a study employs measures to minimise biases, focussing on internal validity. • Internal validity (validity) is the degree to which the results of a study are likely to approximate to the ‘truth’. It is a prerequisite for external validity. • External Validity (generalisability, applicability) is the extent to which the effects observed in a study are applicable outside of the study ( in routine practice) Alhashimi

28. Step 6: Publication of The Systematic Review • Published by Wiley in the Cochrane Library available online for subscribing countries or in CD issued 4 times a year. • The review is the full responsibility of the reviewer. He/She is committed for alerting for any new relevant RCT’s and updating the review. • Reviewers who fail to update will risk having their reviews removed from the Cochrane Library . Alhashimi
