Study assesses cancers in children exposed to medical imaging
Study of nearly 4 million children and adolescents finds that 10% of pediatric blood and bone marrow cancers may have stemmed from radiation exposure.
Lower socioeconomic status is commonly related to worse health. But if poor access to healthcare were the only explanation, universal access to care such as that available in Ontario should eliminate the association. Researchers at the Institute for Clinical Evaluative Sciences (ICES) studied patients with access to Canada’s universal healthcare system who were initially free of cardiac disease, tracking them more than a decade. The results appear in this month’s issue of Health Affairs.
“We found that patients from disadvantaged groups used healthcare services more than their wealthier and more educated counterparts because they were sicker. But greater use of healthcare services by people from disadvantaged groups did not translate into better outcomes, particularly with respect to mortality. We need to start thinking about health and not just healthcare,” says principal investigator and ICES Scientist, Dr. David Alter.
The study of 14,800 patients who were all initially free of cardiac disease found:
“Countries contemplating national health insurance cannot rely on universal healthcare to eliminate, but rather only to reduce, historical disparities in outcomes suffered by disadvantaged groups. Our findings suggest the need to introduce large-scale preventive strategies early in patients’ lives to help change unhealthy behaviors,” says Alter.

ICES is an independent, non-profit organization that uses population-based health information to produce knowledge on a broad range of healthcare issues. Our unbiased evidence provides measures of health system performance, a clearer understanding of the shifting healthcare needs of Ontarians, and a stimulus for discussion of practical solutions to optimize scarce resources. ICES knowledge is highly regarded in Canada and abroad, and is widely used by government, hospitals, planners, and practitioners to make decisions about care delivery and to develop policy.
