Technology Update – EKG Analysis

Gresham Bayne MD

The most common “technology” question coursing through the AAHCP ListServe these days is “What type of EKG machine do you use?” The use of EKG in home care for physicians provides a simple, portable documentation of both the rhythm strip and, if necessary, a full 12-lead EKG. Some devices allow for one-touch visualization of the rhythm strip with memory capture for remote print-out but no 12-lead. Since the rhythm strip is often bundled into any E/M service rendered that date (even if at a different time), and the removal of the transportation fee for EKG lowers reimbursement to about $24 for both technical and professional components, it is important to analyze the purchase of such machines carefully.

The use of an EKG machine in the office setting with the occasional housecall may lead to a different choice of machine than one for housecalls alone. An office setting allows much higher potential volume of testing and places less imphasis on size and weight than the mobile doctor setting. In the mobile setting, additional factors such as print options, battery life, storage capacity, and heated stylus printing methodology become important. I started doing EKGs on housecalls in 1985 and found the only version available then used a 9-volt battery you could buy anywhere (good) and a heated stylus printer to paper which oxidized quickly in the sun (bad).To make the right choice, an EKG machine must ultimately provide a hard printed record and not lose money, so an analysis with certain assumptions can help prevent “buyer’s remorse.”

Telephony: The Achilles Heel of Home Care?

In my last Technology Column I discussed the wireless broadband revolution and the convenience seen when broadband transmission rates are available in the home care environment with a wireless modem. With fast digital connectivity “anytime, anywhere,” the home care nurse or housecall physician has numerous options for medical “telephony,” or the transfer of voice and data, including e-mail, lab results, and a complete electronic medical record. Unfortunately, few cities have mature wireless “always-on” networks at reasonable costs, and those of us that do are wondering what the recent Chapter 11 filings of Metricom (maker of the Ricochet modems) and Broadband2wireless means to our future.

Robot Blood-Taker Hits The Right Vein Every Time

NEW YORK, Apr 20 (NYT Syndicate) – Have you ever felt like a bruised pincushion after a doctor has tried to take a blood sample but couldn’t find a vein? Help may be at hand in the shape of a robotic blood taker, say engineers at Imperial College in London.

While you might rather put your trust in the haphazard jabs of a medical student than a bloodsucking machine, the researchers at Imperial insist that their robot is far more reliable than a human. Besides hitting the vein first time, every time — a track record few human blood takers can match — the robot won’t overshoot the vein. This is a common problem for some patients that can cause painful bruising. To find the vein, the robot uses a primitive sense of touch. Gently prodding the different parts of the arm, it records the force of the probe bouncing off the tissue to determine what lies underneath the skin with an accuracy of one millimeter.

BioZ Device Aims to Transmit Kidney Patient Data to Docs’ Offices

July 12, CARDIODYNAMICS INTERNATIONAL CORP. (San Diego, CA) announced Wednesday it has submitted a 510(k) application to the FDA in an effort to market a remote monitoring system that enables cardiac data from kidney patients on dialysis to be transmitted to physicians’ offices.

The BioZdTEL uses CardioDynamics’ proprietary BioZ noninvasive impedance cardiography (ICG) technology to ollect hemodynamic measurements, including cardiac output, stroke volume, systemic vascular resistance and fluid status. That information then is transmitted to physicians via the Internet.

Rapid Field Detection of Infectious Agents

WESTPORT, Apr 19 (Reuters Health) – Researchers at the Lawrence Livermore National Laboratory in California have developed an inexpensive, portable instrument, the Advanced Nucleic Acid Analyzer, which they say can be used by epidemiologists in the field for the rapid detection of infectious agents. Dr. Philip Belgrader and colleagues describe the device in the Techview column of the April 16th issue of the journal Science. “Identifying, monitoring, and isolating the source of an outbreak of infectious disease can sometimes be difficult,” they write.

“The process would be greatly facilitated by a portable instrument that could be used in any suspect location and was capable of rapidly detecting and characterizing microbial pathogens.”

Magnetic Resonance Imaging (MRI) Effective For Detecting Deep Vein Thrombosis

Last Updated: 2002-01-14 17:01:14 EST (Reuters Health) By Richard Woodman LONDON (Reuters Health)

Magnetic resonance imaging is a “highly accurate” technique for diagnosing deep vein thrombosis (DVT) and may be particularly helpful to pregnant women and travellers at risk of developing dangerous blood clots, British researchers said on Monday.

Professor Alan Moody and his team in the department of academic radiology at Nottingham University tested magnetic resonance direct thrombus imaging (MRDTI) in 101 patients with suspected DVT above and below the knee. The results were compared with those already obtained using venography by two experts who found that the MRDTI diagnosis was accurate throughout the lower leg venous system.

Vendors Want A Chunk Of Commercial E-911 Applications

By Malcolm Spicer, mspicer@pbimedia.com

Mobile service providers are closely watching the clock as the next implementation deadline approaches for the FCC’s wireless E-911 requirements. At the same time, emergency system dispatchers are looking for answers on how to get the radio and computer equipment they need to process wireless E-911calls.Boulder, Colo.-based wireless data management technology vendor Intrado [TRDO] is expanding its location technology offerings to include what public safety answering points (PSAPs) need. Intrado, which this month changed its name from SCC Communications, will roll out its “PS-MAP” offering in August, Dan Hoskins, vice president and general manager of Intrado’s wireless business unit, told Wireless Today.”In order to be able to provide that 911 service in terms of supporting the wireless carriers, one of the big issues is the technology at the PSAP,” Hoskins said. “We think that [PS-MAP] will help take that problem off their back.”
