Tiny Digital ‘Tags’ Improve Eye Care by Tracking Every Step


Technology that retailers use to make a buying expertise extra environment friendly could additionally profit your subsequent eye appointment.

Called radiofrequency identification, or RFID, the instrument helps streamline operations by realizing the place the whole lot is and the place the whole lot goes. It can help a big retailer preserve a clearer image of stock counts, for instance.

At the University of Michigan Kellogg Eye Center, RFID serves one other goal: to trace and scale back affected person wait occasions and improve time spent on the physician’s workplace.

A partnership between Kellogg and the U-M Center for Healthcare Engineering and Patient Safety (CHEPS) unlocked a complete new realm of potential purposes for RFID know-how.

“We have been attempting to grasp how one can higher combine schooling into the glaucoma clinic go to,” says Paula Anne Newman-Casey, M.D., an assistant professor of ophthalmology at Michigan Medicine. “And it took on a lifetime of its personal.”

RFID uses small tags or chips to transmit a sign to distant scanners. Over the previous decade, the tags have gotten low cost sufficient to connect to on a regular basis objects, from soup to leggings — they usually’ve been utilized in automotive ignitions and digital toll cubicles for years.

Which is why Kellogg medical doctors, ophthalmic technicians, medical assistants and greater than 2,000 sufferers within the glaucoma clinic agreed to put on ID tags implanted with an RFID chip.

What resulted was a “sensible clinic” with real-time localization of well being care suppliers and steady seize of affected person wait occasions. Wait time was measured as any interval {that a} affected person was alone — and never getting assessments or being examined or recommended by a supplier.

“Good decision-making is dependent upon good information, and RFID tags enabled us to get up-to-the-second granular information to really perceive how sufferers and suppliers transfer via the clinic,” says Amy Cohn, Ph.D., affiliate director of CHEPS and a professor of business and operations engineering.

Efficiency improves care

Most eye care professionals know that clinic visits are already lengthy. And wait occasions are a serious indicator of whether or not sufferers are pleased with their well being care.

A brand new affected person’s go to can take two to a few hours with a number of assessments, such as a visible discipline check to detect blind spots and different defects that could be indicators of eye issues.

Using the RFID information, the sensible clinic team at Kellogg can now experiment with adjustments in scheduling, staffing and operations inside a simulated mannequin of the clinic and decide with 80 p.c accuracy the impact on affected person wait occasions.

Even higher, the information might also increase effectivity of clinic visits to incorporate extra schooling and counseling alternatives.

Among them: one-on-one teaching to enhance sufferers’ treatment adherence and dialogue about new glaucoma treatments.

As a glaucoma specialist, Newman-Casey is aware of self-management is a serious concern. Glaucoma is a number one reason behind irreversible blindness within the United States. Yet not less than half of glaucoma sufferers don’t take the medicines that prevent imaginative and prescient loss.

With assist from the National Eye Institute and Research to Prevent Blindness, Newman-Casey is making a strategic framework to address the issue.

“We hope to schedule sufferers in a extra respectful means that acknowledges the complexity that goes into glaucoma care and acknowledges the burden on sufferers of managing a power illness,” says Newman-Casey, who is also refining an online software that helps prepare medical assistants to inspire and assist glaucoma sufferers.

Through early evaluation and schedule adjustments, the glaucoma clinic has been in a position so as to add extra affected person appointments with out growing affected person waits.

Boosting transparency

The RFID monitoring know-how fulfilled a needn’t simply achieved with current digital medical document techniques that may inform when appointments begin and end.

RFID can detect the place backlogs are taking place and when sufferers are left ready.

Another sensible clinic innovation: a dashboard interface developed by Michigan Medicine’s info know-how employees that uses RFID monitoring information to point how a lot time clinicians and sufferers have been in every room.

When in use, an ophthalmic technician monitored the dwell feed. On display, sufferers have been represented by dots that grew greater as they waited.

Doctors would sometimes be alerted about sufferers in limbo who wanted a pleasant reassurance that they’d be seen quickly.

The use of RFID has since drawn the eye of the Office of Patient Experience at Michigan Medicine, which could someday use the simulation mannequin throughout its amenities.

“(The mannequin) is shut sufficient to how our clinic operates that if we need to check new concepts, we will do it on this simulated mannequin to find how it could impact affected person quantity and affected person occasions before we roll it out,” says Newman-Casey, additionally a policy researcher on the U-M Institute for Healthcare Policy and Innovation.

For now, it’s serving to add worth to each second for Kellogg sufferers and suppliers.
