High income earners use more diagnostic imaging

08.11.2005


Universal health care systems such as Canada’s exist, to a very large extent, because access to health care is considered a fundamental right of everyone, irrespective of income and social status. While there is good evidence that access to acute medical care such as cardiac surgery is equitably distributed across income groups, there is little evidence regarding access to the expanding array of diagnostic imaging procedures such as CT scans and MRIs.



In this study, investigators looked at over 300,000 imaging procedures in Winnipeg over a 1 year period. Unexpectedly, rates of diagnostic imaging were almost always higher in the highest income groups. Compared with patients in the lowest-income categories, patients in the highest-income groups were much more likely to receive general radiology, ultrasound, MRIs and CTs.

The relative higher frequencies of access to these procedures among higher-income individuals held for all age groups and for all but a few procedures. Only for obstetric ultrasound were rates of use for women in the lowest-income group higher than those for women in the highest-income group. All of these comparisons took into account the patient’s level of illness (morbidity). The differences in rates of utilization varied, but of 36 analyses, 21 were significant; in 8 of the significant analyses, utilization rates were more than twice as high in the highest-income groups, and these tended to occur in patient groups who were most ill.


This study has important implications for social policy in Canada, and by extension to other countries with universal health care policies and social goals.

The study is limited by the fact that it was done in a single city. Access to diagnostic imaging is dependent on the availability and distribution of equipment and personnel, on the management of wait lists, and on other factors that influence access to health care, such as the density of primary care physicians per population and patterns of medical practice and referral.

Nonetheless, the large sizes of the differences in access make this an important study.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
