A small subset of patients with open-angle glaucoma (OAG) account for a large proportion of all glaucoma-related charges in the United States, according to new data published by researchers at the University of Michigan Kellogg Eye Center and Washington University, St. Louis.
These findings have importance for future evaluations of the cost-effectiveness of screening and treatment for glaucoma.
"We've identified risk factors associated with patients who are the costliest recipients of glaucoma-related eye care," says Joshua D. Stein, M.D., M.S., glaucoma specialist at Kellogg. "Among these factors are younger age, living in the northeastern United States, undergoing cataract surgery, and having other eye conditions. Understanding the characteristics of these individuals and finding ways to reduce disease burden and costs associated with their care can result in substantial cost savings."
The study, published in the September 2012 issue of the American Journal of Ophthalmology, reviewed claims data from 19,927 patients with newly diagnosed OAG who were enrolled in a large U.S. managed care network.
The researchers identified glaucoma-related charges for all such patients from 2001 through 2009. They found that the costliest 5 percent of enrollees were responsible for $10,202,871, or 24 percent, of all glaucoma-related charges. They also found that glaucoma patients generally consume the greatest relative share of resources during their first six months of care after diagnosis.
"Although there have been several studies examining the cost of caring for patients with glaucoma, most have been based on individuals who have already been diagnosed, and few have examined changes in cost of care over time," says Stein. "In this investigation, we examined two questions: What is the pattern of resource use for patients with OAG during the first seven years after disease onset, and what are the characteristics of those patients who have the greatest glaucoma-related resource use."
A chronic, progressive, incurable disease that affects more than 2 million individuals in the United States and many more worldwide, OAG is the most common cause of blindness among African Americans. OAG is the most common form of glaucoma in the United States. Caring for patients with OAG in the United States carries a total societal cost estimated at nearly $1 billion annually.
"Developing an understanding of the resource use of people with glaucoma and identifying those expected to have the largest resource use is important in a resource-constrained health care environment," says Stein. "Further, by collecting longitudinal information on resource use we can better quantify the value of slowing glaucoma progression through various interventions."
Stein is a member of U-M's Institute for Healthcare Policy and Innovation, which brings together hundreds of U-M researchers who study and test ways to improve patient care.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
