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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
