Australian children living with rare diseases:health service use and barriers to accessing care

Background Children with rare diseases experience challenges at home and school and frequently require multi-disciplinary healthcare.We aimed to determine health service utilization by Australian children with rare diseases and barriers to access-ing healthcare.Methods Parents completed an online survey on health professional and emergency department(ED)presentations,hospi-talization,and barriers to accessing services.Potential barriers to service access included residential location(city,regional,remote)and child health-related functioning,determined using a validated,parent-completed measure-of-function tool.Results Parents of 462 children with over 240 rare diseases completed the survey.Compared with the general population,these children were more likely to be hospitalized[odds ratio(OR)=17.25,95%confidence interval(CI)=15.50-19.20]and present to the ED(OR=4.15,95%CI=3.68-4.68)or a family physician(OR=4.14,95%CI=3.72-4.60).Child functional impairment was nil/mild(31%),moderate(48%)or severe(22%).Compared to children with nil/mild impair-ment,those with severe impairment were more likely to be hospitalized(OR=13.39,95%CI=7.65-23.44)and present to the ED(OR=11.16,95%CI=6.46-19.27).Most children(75%)lived in major cities,but children from regional(OR=2.78,95%CI=1.72-4.55)and remote areas(OR=9.09,95%CI=3.03-25.00)experienced significantly more barriers to healthcare access than children from major cities.Barriers included distance to travel,out-of-pocket costs,and lack of specialist medical and other health services.Conclusions Children with rare diseases,especially those with severe functional impairment have an enormous impact on health services,and better integrated multidisciplinary services with patient-centered care are needed.Access must be improved for children living in rural and remote settings.
