Ambulant health care utilisation among children of childhood cancer survivors in Germany.

Within the framework of a questionnaire-based health survey in Germany, we examined ambulant health care utilisation among childhood cancer survivors' offspring compared to utilisation among children of the general population. In total, 1299 former patients received a questionnaire for every known biological child in two cross-sectional surveys, 2013/14 (n = 393) and 2015/16 (n = 906). For investigation of health care utilisation, questions on frequencies and kind of ambulant medical services were chosen for bivariate and multivariate analyses. Correlations between utilisation and anxiety, diagnosis of the parent, pain or preterm birth of the child and social indicators were conducted. For comparison with the general population, data of 17,640 children and adolescents aged 0 to 17 years were used for matched-pair analysis. These data were available from the KIGGS baseline study on the health of children and adolescents in Germany, conducted by the Robert Koch Institute. Overall, 852 (65.6%) of the contacted 1299 survivors completed 1340 questionnaires on their children's health. Childhood cancer survivors' offspring showed a similar attendance of ambulant primary health care compared to the general population (paediatricians 83.1% vs. 82.1%). However, the majority of specialist physicians was visited significantly more often (e.g. dermatologist 10.5% vs. 6.2%) by childhood cancer survivors' offspring compared to children from the general population. Logistic regression showed that parental diagnosis and anxiety on children's health significantly influenced health care utilisation. Further improvement of after-care for childhood cancer survivors by including topics on offspring seems necessary. Offspring's paediatricians should implement counselling and providing of information considering the special family anamnesis.
