NISH (NITAG Support Hub) 5 : Interventions to promote routine vaccine coverage: Research question and PICO

This LibGuide complements the Evidence Gap Map 2

Focus

Review evidence assessing the relationship between personal / recipient OR provider OR health system OR policy / legislative specific factors impacting on vaccine coverage. In addition multicomponent interventions, i.e. a combination of interventions to improve coverage; and multilevel interventions, i.e. interventions delivered simultaneously at different levels will be evaluated.

Research question

Research question:

What is the size and nature of the existing review evidence on interventions to improve vaccine coverage?

PICO

  1. People
    1. All populations in all countries and regions will be included
    2. Only studies published in the last 10 years will be included
  1. Intervention
    1. Any intervention/strategy designed to improve vaccine coverage that focusses on recipient or provider or health systems factors or combinations thereof.
  1. Comparator
    1. No intervention or standard practice
  1. Outcomes
    1. Primary outcomes of: Vaccine coverage.
    1. Secondary outcomes of: intermediate outcomes such as KAP, intention to change behaviour, etc.
    2. Secondary outcomes of – impact of vaccine coverage, eg mortality and morbidity from vaccine preventable diseases

Only include studies covering primary outcomes. Within these included studies, we will extract data on secondary outcomes.
