Ripi – Regional Inequality of Health Care in Children

Regional inequality of health care for chronically ill children: the effect of small area deprivation on outcomes in pediatric inflammatory bowel disease


The ripi study was prompted by the observation that the quality of health care for children with inflammatory bowel disease (IBD) shows regional differences, e. g. with regard to timely diagnosis. Therefore, the aim of the prospective cohort study "Ripi" was to evaluate the quality of care among children and adolescents aged 10–15 years affected by IBD and to identify possible causes for regional disparities. In the evaluation, possible factors influencing the quality of care are considered on several levels:

  • Individual (child, parents): Socioeconomic factors, e. g., parental income and education, migration status, treatment adherence, insurance status, disease-specific factors
  • Social disadvantage of region of residence (at county level)
  • Medical providers: quality of medical care at the level of supervising family doctor or pediatrician and specialist.

This will examine whether there is a relationship between these factors and the age-appropriate growth of children/adolescents or their disease-related quality of life (outcome-based quality of care). In addition, various indicators of structural and process quality will be explored.

The study was conducted at BIPS in cooperation with the Helmholtz Zentrum München (Institute for Health Economics and Health Care Management) and DCCV e. V.
