QRS Software-based Medical Devices in Computer Cards Reduce the Complexity and Cost of Diagnostic Testing

The 325,000 primary care physicians in the U.S. are on the front lines contending with the central challenge of our health care system: providing quality care at an affordable cost. They need convenient, reliable and reasonably priced devices for diagnostic testing and patient monitoring. Founded in 1994 and headquartered in Plymouth, Minn., QRS Diagnostic designs and develops software-based medical devices, built into computer cards, which cost 25 percent to 50 percent less than traditional device products.

“QRS is a medical device company that thinks and acts like an information technology company,” says Spencer Lien, founder and chief executive officer, QRS. “We apply our patented technology to convert standard computing devices, like laptops and PDAs, into portable, upgradeable and affordable medical devices.”

The Problem: The Complexity and Costs of Medical Devices--

Grappling with government and managed care payment constraints, primary care physicians (those in general practice, family practice, pediatrics and internal medicine) must uphold quality while managing costs. To cover practice overhead and maintain their incomes, they strive to see more patients per day. If they could readily and effectively perform more diagnostic tests in their own offices, primary care physicians could maximize the clinical value of office visits, improve quality, and enhance convenience for patients. They could also reduce costs and increase their share of revenues by performing tests for many patients themselves, instead of always referring them to specialists. And, instant access to test results enables primary care physicians to communicate more effectively with specialists when they do refer their patients for a consultation.

Yet, many primary care physicians still do not perform diagnostic procedures such as spirometry and electrocardiography. Why? Most medical devices are not designed for primary care physicians. They are too cumbersome, too complex, and too costly.

The QRS Technology Solution: Computer Card Medical Devices--

QRS uses its innovative technology to design and develop medical devices that streamline and simplify the collection, interpretation and communication of precise physiological data. QRS enables primary care physicians to cost-effectively practice high-tech medicine while delivering the accuracy that specialists and hospitals demand. The company focuses on the unmet needs of primary care physicians while offering cost-effective device alternatives for hospitals as well as the approximately 50,000 specialists in the U.S. who practice cardiovascular medicine.

QRS holds two patents on the design of medical devices contained in Type II (PCMCIA) PC Cards and Compact Flash (CF) Cards for Windows(R) CE-based handhelds and Pocket PCs, including the HP iPAQ™. “We build the intelligence of physiological data acquisition and analysis into computer cards,” explains Lien. “QRS computer cards, with integrated sensors (such as electrode leads for EKGs), slide right into off-the-shelf laptops, Pocket PCs and PDAs. This makes them work as fully functioning medical devices, and that’s the key to the mobility and affordability of our products.”

Portability, as well as affordability, is an advantage. In the offices of primary care physicians, it is often infeasible or too costly to maintain dedicated procedure rooms for bulky, stand-alone diagnostic testing machines. Physicians can carry QRS devices in their lab coat pockets. Because they are software-based, QRS devices are not only mobile but easily upgradeable, which reduces long-term device costs. Moreover, QRS eliminates the need to purchase and support separate, stand-alone machines for different diagnostic procedures, since a single laptop or PDA can support all QRS computer card devices.

“With QRS, I was able to buy two computer card devices, for spirometry and electrocardiography, for less than the price of an EKG machine,” says Patrick O’Malley, D.O., O’Malley Family Medicine, Oconomowoc, Wisc. “When I want to monitor a patient’s heart or test their lung function, for initial diagnosis or follow-up, it’s easy to do myself. I just plug the QRS card into my notebook PC. It’s simple and fast. And, I don’t have to wheel in a big, unwieldy machine to do the tests.”

Computer Card Medical Devices: The QRS Diagnostic Product Line--

Spirometry is essential in the diagnosis and treatment of conditions such as chronic obstructive pulmonary disease (COPD) and asthma. According to the American Lung Association, about 12 million Americans have COPD, and asthma afflicts an estimated 20 million to 25 million people in the U.S. SpiroCard(R) from QRS Diagnostic is a software-based spirometer contained in a computer card. Weighing less than two ounces, SpiroCard is the smallest and lightest spirometer on the market. Yet, SpiroCard exceeds the accuracy standards of the American Thoracic Society (ATS), and independent testing has verified that SpiroCard is actually more precise than spirometers that are more expensive.

“SpiroCard offers frontline physicians a useful, reasonably priced way to practice state-of-the-art medicine,” says Patrick Zook, M.D., St. Cloud Medical Group, Saint Cloud, Minn.

“SpiroCard from QRS Diagnostic was my first choice because of its accuracy, flexibility, mobility and ease-of-use, and affordability,” says Tom Mayer, C.R.T., C.P.F.T, director of the Lung Health Clinic at Academic Medicine, Inc. (AMI), a seven-physician group practice in Kirksville, Mo. “With its reasonable price, SpiroCard enabled me to get our lung health clinic started with very low overhead costs.”

OxiCard(R) is QRS Diagnostic’s pulse oximeter that provides instant, noninvasive measurement of pulse rates and oxygen saturation in the blood. The device is built into a Compact Flash (CF) Card and weighs only 2.4 ounces. SpirOxCard(R) is the only combination spirometer/pulse oximeter. It measures pulmonary function and monitors blood oxygenation with one convenient device contained entirely in a computer card.

Nick Ausaf, D.O., Lakefront Center for Family Medicine, Sebring, Fla., uses SpirOxCard in his practice. “To meet patient expectations and provide quality care, I want to utilize diagnostic tools, like spirometry, that are appropriate today for primary care, but I must also control overhead costs,” he says. “QRS offers the affordable, high-quality technology solution for diagnostic testing that I envisioned for my new practice, and their computer card devices have proven to be reliable and easy to use.”

Universal ECG™ is a lightweight, portable, 12-channel diagnostic electrocardiograph device, a critical tool in the diagnosis and treatment of heart problems, including Congestive Heart Failure (CHF), which affects nearly 5 million Americans.

“It’s so fast and easy to perform EKGs with the QRS card that I have no need for a technician. Patients appreciate that it takes only a few minutes to put on the leads and run the test,” says Sam Sugar, M.D., Sunrise Lifestyle Centers, LLC, Northbrook, Ill. “For a small to moderate-size practice, it’s an excellent choice for office-based diagnostic electrocardiography.”

Another physician who finds Universal ECG to be the right solution for primary care is Steven Mussey, M.D., Mussey, Sarber and Associates, P.C., an internal medicine practice in Fredericksburg, Va. “We were trying to find a heart monitor we could afford, and the price of Universal ECG was far better than a stand-alone machine,” he says. “I just plug the card into my laptop, attach the leads, and get accurate results.”

QRS continues to employ its patented technology platform to expand its product line. QRS will release its BPCard™ blood pressure device in 2004. VitalsCard(R), which integrates blood pressure, body temperature, pulse oximetry is in development.

Office Medic International enables physicians worldwide to take advantage of QRS medical devices and patient information management software. It offers seven language choices: King’s English, Spanish, German, French, Italian, Portuguese (Portugal), and Portuguese (Brazilian).

Office Medic Integrated Data Management System (IDMS) provides the full advantages of a network solution. It is a patient information management system that provides real-time diagnostic testing, centralized digital data storage, rapid report retrieval and data sharing, and remote connectivity. With Microsoft SQL Server 2000, Office Medic IDMS turns clients on a network into full-function medical devices simply by sliding a QRS computer card device into an existing network workstation. Physicians and nurses can perform tests on any standard client and then access and analyze the results from anywhere on the network.

Office Medic also interfaces with electronic medical record systems (EMRs) to offer added functionality and value for physicians. QRS has partnered with Amicore, Andover, Mass., to interface with Amicore Clinical Management, a comprehensive clinical workflow and EMR solution. “We use Amicore Clinical Management and QRS devices to automate administrative and clinical tasks in our practice,” says Robert Hughes, M.D., Primary Care Medical Center, a seven-physician group practice in Murray, Ky. “With the interface, we will achieve even greater increases in productivity.”

QRS Mobility, Reliability and Affordability: Advancing Home Care--

Today, the mobility, reliability and affordability of QRS devices also advance diagnostic testing and patient monitoring for disease management and home health care. According to Barb Johnston, R.N., clinical nurse specialist, Kaiser Permanente, Los Angeles, Calif., “the devices developed by QRS Diagnostic provide an opportunity for improving disease management for patients with asthma, CHF, COPD and other conditions.”

Texas Children’s Hospital (TCH), Houston, is an internationally recognized, full-service pediatric hospital, the largest in the U.S. The lung transplant program at TCH uses SpiroCard and Office Medic to remotely monitor patients’ post-transplant lung function after the children return home. “Decreased pulmonary function is an early, and critical, indicator of possible graft malfunction,” says George B. Mallory, M.D., program director. “At-home spirometry with digital data storage, remote monitoring and automated communication ensures follow-up care.”

QRS Diagnostic: The Right Technology Propels Fast Growth--

With the basic soundness of the company’s business strategy and the strength of its patented medical device technology, QRS Diagnostic is moving forward.
