RT Journal Article SR Electronic T1 Associations between parental mental health and other family factors and healthcare utilisation among children and young people: a retrospective, cross-sectional study of linked healthcare data JF BMJ Paediatrics Open FD BMJ Publishing Group Ltd SP e000266 DO 10.1136/bmjpo-2018-000266 VO 2 IS 1 A1 Kathryn Dreyer A1 Robert A P Williamson A1 Dougal S Hargreaves A1 Rebecca Rosen A1 Sarah R Deeny YR 2018 UL http://bmjpaedsopen.bmj.com/content/2/1/e000266.abstract AB Objective To identify the degree to which parental diagnosis of depression or other long-term conditions, parental health-seeking behaviours and household factors were associated with a healthcare utilisation among children and young people (CYP) (0–15 years).Design Retrospective, cross-sectional study of electronic health records, from 25 252 patients registered at a large, London-based primary care provider. The associations between children’s healthcare utilisation and the characteristics of the child, their parents/carers and their household structure were examined using multivariable regression.Results Controlling for parental utilisation, parental depression (vs not) was significantly associated with increased healthcare utilisation for CYP. Odds ratios for CYP with siblings=1.41 (95% CI 1.10 to 1.80) for emergency department (ED) attendances, 1.67 (95% CI 1.32 to 2.11) for outpatient appointments, 1.47 (95% CI 1.07 to 2.03) for inpatient admission, and rate rato=1.28 (95% CI 1.04 to 1.78) for general practitioner (GP) consultations.After adjusting for child and parental characteristics, parental general practice attendance (+1 from mean) was predictive of increased CYP general practice attendance, rate ratio 1.07 (95% CI 1.06 to 1.08) for CYP with siblings. Parental ED attendance also increased the risk of CYP ED attendance, with OR 1.27 (95% CI 1.12 to 1.44) for CYP with siblings.Conclusions Parental depression is associated with increased utilisation of ED, outpatient and inpatient services by CYP, as well as with increased GP consultations among adolescents. Our results demonstrate that healthcare utilisation by CYP is associated with the health-seeking behaviour of adults in their household.
