The story of the fallacy of coverage is made up of five theme areas of evidence - timeliness of immunization, social and gender inequities, vaccine efficacy, understanding demand side issues to tailor interventions, and national data sets masking actual district level coverage rates - that reveal the discrepancies in immunization coverage rates and the reasons behind these discrepancies.
Data collection presented two distinct challenges relative to evidence generation: timeliness and comprehensiveness.
However, existing evidence on timeliness of BCG immunisation in Africa is limited by sample size, methodology and scope of factors studied [ 15, 16].
This study contributes to addressing the gap in evidence on timeliness of immunization in urban informal settlements in Kenya as well as other similar settings in low and middle income countries.
A synthesis of patient navigator literature in cancer care found some evidence they increased timeliness of screening and treatment and identified their roles in helping patients overcome health system barriers, providing health education, addressing patient barriers to cancer care, and providing psychosocial support [ 14].
Assessments in both countries found evidence suggesting improved vaccination timeliness and coverage.
A review of documents also revealed the varied timeliness of evidence.
A translation of this filter for PubMed was planned at the outset for two reasons of prime importance to the knowledge translation process: ease of access to evidence, and the maximal timeliness of that evidence.
The timeliness of the evidence varied; some respondents reported that evidence was available while others reported that evidence was only generated to justify a decision that was already made.
The timeliness of the evidence also varied; some respondents reported that there was evidence regarding the ills of user fees, and others reported that evidence was generated after the decision to abolish user fees was made.
The inclusion of positive IgM test results, typically the first laboratory evidence to indicate infection, enhances timeliness of reporting.
