Why this research matters now
The observed disparities underscore potential benefits from focused immunization initiatives aimed at protecting high-risk demographic segments.
Structured evidence summary
Research question
What are the admission frequencies and associated financial burdens of pertussis among French patients managing preexisting health disorders?
Study design
A retrospective examination of longitudinal administrative health records spanning more than twelve years.
Population and setting
Pediatric, adolescent, and adult cohorts documented within the French national healthcare database from 2008 through 2020.
Main findings
Individuals with respiratory illnesses or weakened immune systems demonstrated markedly elevated admission ratios relative to unaffected peers. Financial expenditures reached their peak among immunocompromised patients, whereas adult medical service usage showed no notable shifts surrounding the hospital event.
Public-health relevance
The observed disparities underscore potential benefits from focused immunization initiatives aimed at protecting high-risk demographic segments.
Important limitations
Reliance on hospital discharge documentation inherently excludes milder community-managed infections and limits clinical granularity.
GIDS interpretation
This publication establishes a historical baseline for disease frequency and economic impact within defined risk categories, offering contextual reference for ongoing epidemiological tracking.
Related GIDS surveillance
Literature context does not validate, explain, or change a surveillance signal. Exact and contextual relationships are shown separately.
Evidence relationships
This article has 8 auditable classifier relationships to diseases, places, topics, and study design.
