Objective of EBR related to IAPCOI19th February 2012, IMA House, New Delhi Vipin M. Vashishtha, MD, FIAP Convener, 2011-13 vipinipsita@gmail.com
Why the NEED?? IJMR 2008; 127: 502-03 Indian Pediatrics, 2009,; 46: 1021-23 PEDIASCENE June-Sept. 2001,
Aims & Objectives: • To develop a uniform approach to making explicit the evidence base for IAPCOI recommendations; • To develop, evaluate and apply a system to make evidence based recommendations (both existing and future) for the IAPCOI
Activities & Guiding Principles: • Main focus should be on scientific evidence and transparency so that the system can be reproducible and can also be reviewed by other experts; • Every attempt should be made to avoid bias creeping anywhere;
Activities & Guiding Principles: • The recommendations should entirely be based on available scientific evidences & where no evidence can be found, it should be mentioned clearly in the text • Extrapolations should ideally be avoided as far as possible!!
Activities & Guiding Principles: • No consideration should be given to any other attribute like practicability, feasibility, affordability, etc • While grading recommendations, grade them for the both, individual and community health
Activities & Guiding Principles: What ought to be reviewed? • Existing evidence from the country • Guidelines of various agencies (GoI, ACIP, AAP, EMEA etc) • Existing recommendations of IAP COI • Revise EBR on each vaccine (newer vaccines should be prioritized!!)
Activities & Guiding Principles: Key elements for consideration: • Burden of Illnesses • Safety & Efficacy of the available vaccines, • Cost-effectiveness and economic studies should not be graded!!
Proposed format of EBRs(Methodology of issuing recommendations) • Need to answer few questions: • What is the evidence? • How to look for it? How to access? • How to assess & analyze? • Which is the better evidence? (Hierarchy of evidence) • How to grade the available evidence to issue recommendations? • What are the models available? • Which one to choose?
(GRADE) framework: • Grades of Recommendation Assessment, Development and Evaluation (GRADE) framework
Proposed format of EBRs: Description of Evidence Grades • Proposed evidence grades for safety and efficacy, • A, B, C, D June 2010 ACIP Meeting
Description of Evidence Grades: Note: Grades reflect the confidence in the estimated effect on health outcomes based on a body of evidence. Further research may not always be possible.
Proposed recommendation categories: • Category I (recommendation for, or recommendation against) • Universal recommendation • Risk-based recommendation • Category II (recommendation for individual clinical decision making) • No recommendation/unresolved issue
Examples: • Recommendation: ACIP recommends vaccination of U.S. infants with three doses of rotavirus vaccine administered orally at ages 2, 4, and 6 months • (Recommendation category: I, Evidence grade: A). • Remarks: • Nearly every child in the U.S. is infected with rotavirus by age 5 years, resulting in approximately 410,000 physician visits, 205,000–272,000 emergency department visits, and 55,000–70,000 hospitalizations each year. Benefits of vaccination are large compared to potential harms.
Examples: • IAPCOI recommends TWO/THREE doses of RV1/RV-5 administered orally at ages 6 & 10 OR 6, 10, 14 weeks • (Category: ? Evidence: ? )
Examples: • IAPCOI recommends OPV …… • (Category: I Evidence: A ) • IAPCOI recommendations on Typhoid vaccine: • Vi-PS (Category: I ? Evidence: A/B ) • Vi Conjugate (Category: II Evidence: C/D?)
Examples: Hepatitis A vaccines: • Recommendations for use: (Category : ? ? Evidence: ? ) • Killed vaccine: TWO doses (Category: I Evidence: A) • Live H2 strain: TWO doses (Category: II ? Evidence: B/C )
