Same-day Service: Tucson facility uses “out-of-this-world” technology to turn around results faster

Some 400 years ago, Galileo created a compound microscope based on the optics he first developed for use in a telescope. Earlier this century, a group of optical science researchers from the University of Arizona in Tucson followed his lead.

Technology originally developed to create very large array telescopes has been miniaturized four orders of magnitude and made into a microscope chip. The result was an individual microscope measuring less than 1 cm high and employing aspheric optics.

“We can take 80 of these microscopes and aggregate them into a geometric array, making it possible to scan an entire glass slide in a single sweep. The scan speed is very important to laboratories. The system uses massive parallel processing, which also will have implications for its use in analytical microscopy in the future,” says Ronald S. Weinstein, MD, scientific director of DMetrix Inc, Tucson, Ariz. Weinstein is a co-inventor of this patented array microscope, which, including its camera, is the size of a stack of five quarters. “This technology has made it possible to take a biopsy and replace the traditional overnight processing method and slide readout with a new process that takes a few hours,” he explains.

Clinicians don’t have to be stargazers or lab rats to appreciate these advances. The scanner—marketed as the DMetrix DX-40—is a keystone in the Tucson Breast Center rapid breast service, which was established to master an approach to returning breast biopsy results the same day. This patent-pending process, called UltraClinics, was conceived based on a prior method pioneered by the Arizona Telemedicine Program, which has been providing mammography results in less than 1 hour to women of the Navajo Nation for more than 6 years.

“We started thinking that if we can give them their final mammography report while they are still in the office, why can’t we add the laboratory component and make it possible for them to have both their imaging results and their lab results in the same day?” questions Weinstein, chairman of the board of UltraClinics, who believed the goal was feasible because the vast majority of women who undergo biopsies receive good news. “The major focus of this program is to give same-day results to the 80% of women who are going to have benign breast biopsies. There is an enormous amount of psychological trauma for women when they are waiting for their mammography results—and that amount of anxiety is unnecessary and avoidable with modern technologies.”

Although the rapid scanning capabilities are a vital component, it’s only possible to fulfill a quick delivery promise on a large scale with a highly organized workflow process. The full details of this approach cannot be fully disclosed until the patent process has been completed. Without question, however, the UltraClinics concept would not be possible without the use of telemedicine.

In Tucson, the UltraClinics process begins in the morning with a breast biopsy. The specimen is then transported to a laboratory, located several miles from the clinic. The DMetrix DX-40 is used to quickly provide laboratory results. If a pathologist is available on-site, the diagnosis is made immediately; if one is not on-site, a remote pathologist accesses “virtual slides” via the Internet and provides a diagnosis.

“If it’s benign, they immediately issue a report,” says Weinstein, who is also professor and head of the department of pathology at the University of Arizona College of Medicine and founding director of the Arizona Telemedicine Program. “If a malignancy is identified, we don’t submit a report until we get a second opinion from another pathologist in our group practice. Because the second pathologist is not at the same location as the processing laboratory, that processing lab scans the slides and a pathologist at another site renders the second opinion.”

Enlisting this type of point-of-care availability from pathologists makes it possible to deliver results within hours; it also enables much of the UltraClinics rapid turnaround process.

“Scheduling becomes a major challenge in creating these kinds of services, because it requires the doctors to develop an awareness that they’re going to have cases to provide service on and determine how to incorporate them into their very busy schedules,” Weinstein explains.

Complicated though it may be, combining breast imaging and rapid laboratory reporting is working. More than 6,000 Navajo women have benefited from this accelerated turnaround, and, since its May 2006 opening, UltraClinics at the Tucson Breast Center has provided same-day results for about 150 biopsies.

Outside of breast imaging, there is no technical reason the UltraClinics process couldn’t be applied to a variety of specialties, according to Weinstein. The process is already being used to provide quick results for prostate specimens, and the technology could be just as effective for colon biopsies and dermapathology.

“We also have expanded to perform rapid processing of kidney biopsies from transplant patients, and we are impressed with the excellent reception of our in-house clinicians,” he says. “In just 3 or 4 hours, they are getting answers that used to take overnight, so it really changes the clinician’s mind-set as to what service can be. It puts them on a different timeline as they go through the critical pathway.”

The goal for Weinstein and his colleagues is to make this type of processing available to existing breast imaging centers, either by equipping them with their own modular laboratories and providing them with off-site telepathology diagnostic services, or by providing access to nearby service centers that would handle the rapid tissue processing and provide expedited access to a diagnosis. Not only would it change the current service model, but also, access to the tissue processing revenue presents a unique opportunity for imaging centers seeking a respite from cutbacks in compensation.

“I’ve been the pathology chair for 30 years, and most of the patient care phone calls I get are about women who want to know the results of their breast biopsy,” Weinstein says. “We have found a way to address that problem, bringing it to the mainstream to the point where we have done many patients and understand this practice model inside and out—and we did it with a lot of care and attention to quality issues. Patient satisfaction is high, and that’s very gratifying.”

Remote MRI in Action at UCLA

by Cat Vasko

Radiologists at the University of California, Los Angeles (UCLA) David Geffen School of Medicine have successfully tested computer software that allows them to control MRI examinations remotely via the Internet. When perfected, the technology could be used to train technologists in difficult procedures and to connect experts with patients requiring difficult cardiac or vascular scans.

“As long as you can establish connectivity between one computer and another, and assuming you have the right administrative permissions, you can take over the computer,” explains J. Paul Finn, MD, chief of diagnostic cardiovascular imaging at UCLA. “That’s often what technical support people do when you’re having a problem with your computer, and it’s the same principle with MRI. The machine is run by a computer, and when you log in remotely, what you see on your screen is pretty much what the technologist would see at the scanner interface.”

J. Paul Finn, MD, remotely controls an MRI scanner a half mile away.

Siemens Medical Solutions, Malvern, Pa, made a few modifications at UCLA to allow Finn and his team to remotely control the vendor’s 1.5T MRI systems; Finn sees no reason why analogous alterations couldn’t be made to other types of scanners from other vendors. Siemens Medical currently has FDA approval to use the software within the UCLA Medical Center via the facility’s intranet, and already, Finn has scanned 30 patients at the hospital from his office a half mile away.

But Siemens Medical has yet to apply for permission to use the software over the Internet. Finn explains why adoption of this application has been so sluggish: “First, you need to have a good Internet connection. In order for this to be practical, you need to have a pretty good responsiveness at your computer. When you click on a window or click on a menu, you’d like it to respond fairly quickly. If it doesn’t, and if you have too much of a lag, it’s just impractical. It takes too long, and you get frustrated.”

The benefits of pursuing remote scanning technology are threefold. “The reason we set it up here originally was because, like lots of large medical centers, we have MRI scanners in several different physical locations,” Finn says. “One of our areas of interest is cardiac and vascular MRI, and these types of studies are not the easiest to run. The technologists need to be specifically trained in cardiac and vascular imaging, and not all of them are, and I think that’s the case in most institutions.” Indeed, when Finn’s 30 remote cardiovascular scans were compared with 30 scans performed by an on-site technologist, 90% of his were rated excellent by other radiologists, compared with just 60% of the on-site scans.

In addition, once the scanner is being controlled remotely by an expert, Finn notes, “The technologist there can look on and see every move that’s made, every change that’s made, and learn from the experience. So, it can be used to do studies that you wouldn’t otherwise be able to do, and it also can be used as a training tool, because you can talk local technologists through the procedure and train them while you’re doing it. So, the patients benefit by always getting expertise, and the local technologists benefit because they can get online training when needed.”

A third advantage to remote scanning is the potential for greater consistency in multicenter trials. “Let’s say you have a whole variety of different sites participating in the trial, and you’d like them all to be doing things according to a well-controlled protocol,” Finn explains. “That can be extremely difficult to standardize right now, and it’s extremely difficult to guarantee quality control. But let’s say you were able to establish Internet connectivity between all these sites and all these machines. Then you could work with the local technologist and make sure that all of these studies were done as closely as possible to the research protocol, and at the same time, you could help train the local people as you went.”

However, Finn warns, respecting the territory of the local technologist is a must. “You don’t want to give people the idea that they’re not doing a good enough job,” he says. “You need to be sensitive to this. You don’t want to come in aggressively implying that they can’t do the advanced stuff. It should really be used as a support tool, in a positive way, and then I think people will respond very well to it. There are human issues as well as technical issues, and in some ways, the human issues are more important. But we now have the technology to distribute skill and expertise across the Internet for medical care. It’s a fantastic advance.”

A Safe Bet: BetterHealth provides a seamless introduction to EHR

by Dana Hinesly

Modern technology has revolutionized the way radiologists work. A single physician can read for multiple imaging centers—from the comfort of his or her own home, in many cases. However, with the perks comes a modicum of inconvenience.

“Do you know how many Web sites physicians need to access these days? They have the hospital’s Web page, Lab Corp’s Web page, Quest’s Web page, the imaging center’s Web page; and the transcription company typically has a Web page,” says Jack Kemery, president of BetterHealth Global (USA) Inc, a subsidiary of Health One Global Ltd, West Chester, Pa. “There is an advantage to a physician’s office not being required to go to all of these sites.”

BetterHealth offers just such an advantage, providing physicians with a central location from which to receive every piece of patient-related data transmitted electronically. Arguably, the most beneficial aspect of the system is that it is a single solution.

Consisting of two components—BetterHealth exchange and BetterHealth record—the product acts as a document manager: It accepts, identifies, and files every piece of data it receives. The data can come in any form. Anything currently recorded or noted in a paper file—including captured images or links to other relevant information—can be accommodated.

BetterHealth exchange acts as a document clearinghouse. Facilities working with BetterHealth send their information to it, and the information immediately is routed to the appropriate source. On the receiving end, BetterHealth record is a complete EHR solution that accepts the electronic data and categorizes it accordingly.

Once in BetterHealth record, not only is the data put in its appropriate place—a pathology report in the corresponding patient’s file, for example—but it becomes a searchable database.

“What makes BetterHealth record unique is its architecture; it is a very granular EHR. Every data element is an object in and of itself, so there is no predefined record layout or database segment,” Kemery explains. Because of this, queries can be as general or as specific as the user chooses. ” ?Last name’ is an object, ?first name’ is an object, ?diagnosis’ is an object, ?report’ is an object. Actually, ?report’ can be text, or it can be a link to an external document on someone else’s database on another computer somewhere else in the world. It doesn’t matter to us, because the attributes tell BetterHealth record how to handle it.”

Robert A. Ruggiero, MD, FACS, senior partner of Main Line, uses the BetterHealth system.

Managing the flow of information through one Web site instead of many is a definite advantage—to some physicians. Others choose to get only some information sent to them through the system, which can be upgraded to meet the facility’s needs and comfort level. If so desired, BetterHealth can provide a totally integrated EHR solution allowing all dictated notes, external reports, lab results, instrument interfaces, images, scanned documents, and direct dictionary-based data capture to be incorporated directly into the patient’s record.

Requirements for installing BetterHealth are a computer (laptop or desktop) and an Internet connection. Training requirements are negligible, and, once in place, it has little to no impact on the user’s established workflow.

Streamlining at Main Line

BetterHealth recently forged a partnership with Main Line Diagnostic Imaging and Women’s Center, a group of three private, physician-owned outpatient full-service radiology centers located in Bryn Mawr, Downingtown, and Malvern, Pa.

“More and more, people are talking about EHRs, and this puts us at the cutting edge, because we are one of the first outpatient radiology centers in the area to be able to offer this type of service to our physicians,” says Barbara Atherholt, director of marketing at Main Line. “In the future, patients will have access to their own records, and this is a vital next step to allowing that to happen.”

Main Line is using BetterHealth technologies to deliver reports electronically. The system mirrors the prior report process in which reports were dictated, transmitted electronically for transcription, then forwarded to the physician via fax. With BetterHealth, the report doesn’t end up as one more piece of paper to file; it is entered into the patient’s file instantly and automatically.

As part of their collaboration, BetterHealth is being provided to Main Line’s physicians as a complimentary service. In addition to speeding up and improving the accuracy of the report-delivery process, being able to provide this type of EHR solution has helped increase Main Line’s referrals.

“It’s a win-win for everyone. The providers save the cost of faxing documents and managing follow-up calls, and physicians’ offices benefit because they handle less paper and things aren’t lost,” Kemery says. “They’re just there, neatly organized by category in a patient’s chart.”

BetterHealth currently is working with Main Line to make it possible for the imaging centers to take advantage of other available features. The current implementation deals only with the radiologist’s reports. Once the next phase is complete, Main Line’s physicians will be able to view study images with the imaging center’s specialized viewer. Images themselves will not need to be stored redundantly in the facility’s computer system.

In addition to improved report delivery, the arrangement with BetterHealth presents another benefit to Main Line’s referring physicians. “A lot of the physician practices use paperless programs or believe in the concept; they do not want paper,” Atherholt says. “With BetterHealth, we still have an electronic delivery system so that once the report is transcribed, it is sent directly into the patient chart and there is no paper.”

Main Line also is giving its clients access to a “try before you buy” scenario. “The facility is giving its customers an opportunity to try their hand at document management and, ultimately, an electronic health record, without the up-front investment, worry, and fear that most physicians’ offices have around it,” Kemery says. “The physician has an opportunity to explore and move very gradually into a full EHR should they decide to, as they learn and become more confident.”

TGE Program Protects High-Density Data Centers

American Power Conversion Corp (APC), West Kingston, RI, has launched a Thermal Guarantee Equipment Protection Program, offering financial compensation for properly protected and certified installations damaged by a thermal event, a growing risk in the high-density data center. APC offers its InfraStruXure Hot-Aisle Containment System and its Rack Air Containment System; deploying these in new or existing environments ensures the repair of or reimbursement for up to $150,000 of protected hardware damaged by a thermal event.

“Although events like power surges and blackouts are well known in the IT and facilities communities, many customers are just now comprehending that IT equipment also has a thermal envelope specified for proper operation,” Aaron

L. Davis, chief marketing officer at APC, said in a press release. “Exceeding high or low temperature thresholds too quickly can create thermal surges, and complete loss of cooling—called cooling blackouts—can lead to immediate and unintended server shutdown in the exact same manner as during power blackouts. A key difference is that power blackouts give ample notice through loss of lighting, but loss of cooling may go unnoticed until it’s too late.”

To earn the Thermal Guarantee certification, a customer must work with a team of APC professionals to design a customized plan that reaches IT system availability targets and provides substantial total cost of ownership savings. The customer also must agree to five steps:

  1. Assessment: a comprehensive analysis of a customer’s existing capacity, with consideration of current and future power and cooling objectives.
  2. Design: using assessment results to develop a high-density InfraStruXure solution.
  3. Implementation: deploying and certifying the InfraStruXure solution using APC’s Hot-Aisle Containment System or Rack Air Containment System.
  4. Postimplementation Monitoring: continuous physical and environmental monitoring of the customer’s network-critical physical infrastructure environment.
  5. Periodic Review: semiannual assessment and preventive maintenance of a customer’s power and cooling, along with next-day on-site service.

The InfraStruXure Hot-Aisle and Rack Air containment systems use InRow design to ensure cooling predictability, capacity, and efficiency; an array of monitoring options enable the industry’s best solutions for thermal management.

“There are many confusing and conflicting claims about the right approach to data center power and cooling,” Davis said, “and this latest certification continues our history of providing not only innovative technology but also maximum clarity and peace of mind to our customers.”
