Mayo Clinic Finds New Pathology Tests Double Sensitivity to Detect Bile Duct and Pancreatic Cancers

Pancreatic cancer and bile duct cancer are difficult to diagnose and often fatal because they are discovered in the advanced stages of the disease. Researchers have developed new tests that double the ability to detect bile duct and pancreatic cancers, according to a Mayo Clinic study published in the June issue of Gastroenterology.

    -- Additional audio and video resources, including excerpts from an interview with Dr. Lewis Roberts describing the research, are available on the Mayo Clinic News Blog, password: fish059.

Pancreatobiliary tumors such as bile duct cancer (cholangiocarcinoma) and pancreatic cancer often present as strictures, or a narrowing of the duct that can either be caused by benign inflammation or cancer. Physicians insert an endoscope down the throat and into the bile duct and pancreas region to examine possible tumors; however, the narrowness of the bile duct makes it difficult to distinguish benign and malignant strictures.

In this study, 498 patients with pancreatobiliary duct narrowing underwent an endoscopic procedure, and cell brushings were taken. Brushings were then analyzed by routine cytology, digital image analysis and fluorescence in situ hybridization (FISH) to determine the various tests' effectiveness and sensitivity in detecting and diagnosing cancer. While traditional cytology analysis relies on identifying abnormally shaped cells, the FISH test detects malignant cells using colored probes visible with a fluorescence microscope. Since cancer cells have an abnormal amount of DNA, by FISH these cells show extra copies of the probes compared to normal cells. The Mayo research team found that the combination of cytology and FISH raised the detection rate of bile duct and pancreatic cancer from 20 percent to 43 percent. "Bile duct and pancreatic cancers are very difficult to diagnose," says Lewis Roberts, M.B.Ch.B., Ph.D., Mayo Clinic gastroenterologist and the study's senior author.

"We were very pleased to see that the combination of FISH and cytology significantly improved our chances of diagnosing patients reliably. The earlier we can diagnose a patient, the better the types of treatment we can offer and the more likely they are to have long-term survival after treatment."

Treatments for bile duct cancer vary with the size of the tumor and how far it has advanced. These tumors usually grow slowly and spread gradually. In many cases, bile duct cancers are diagnosed at later stages. Current treatments include surgery, liver transplantation, chemotherapy, radiation therapy, photodynamic therapyand biliary drainage with plastic or metal stents. If the cancer cannot be completely removed by surgery but has not spread outside the liver, chemotherapy and radiation followed by liver transplantation may be an option. Mayo Clinic is one of the few medical facilities that offers a liver transplant protocol for early-stage bile duct cancer patients.

Bile duct cancer is rare and is most common in people aged 50 to 70. Approximately 5,000 cases of bile duct cancer are diagnosed in the United States each year, and the incidence of bile duct cancer is on the rise. Between 35,000 and 40,000 cases of pancreatic cancer are diagnosed per year in the United States.

Dr. K. Halling and Mayo Clinic have a financial interest in technology used in this research. Dr. Halling and Mayo Clinic have received annual royalties greater than the federal threshold for significant financial interest from the licensing to Abbott Molecular of other technology related to this research.

Mayo Clinic's Division of Gastroenterology and Hepatology has been ranked #1 in the U.S. News & World Report Honor Roll of Top Hospitals since the rankings began 19 years ago.

Recent paper on legal aspects of teleconsultation

One of our recent GI/liver pathology fellows completed a manuscript that addresses the key points of the legal and regulatory environment involving teleconsultation in pathology.  The paper will appear in an upcoming issue of Human Pathology

Summary

A pathologist may practice telepathology in another room from the original slide using the hospital intranet, he/she may practice it if a CD-ROM is reviewed with a “virtual histologic image” or digital slide. As pathology becomes increasingly subspecialized, and pathologists are progressively more engaged in practices situations where they may not be in a centralized laboratory location, use of telepathology technology may be increasingly common. We touch on select medicolegal and reimbursement issues in the practice of telepathology. Primary and secondary legal sources are reviewed, as well as primary medical references. Telepathology is an evolving area of telemedicine. Guidelines for primary opinion telepathology should be driven from best practices in conventional laboratory procedures and can enhance the practice of pathology. However, it should be undertaken with the understanding that the legal and regulatory environment involving such practices is evolving as well.

A Quality Pathology Report, Voice in the Wilderness

What does the social networking MD network, Sermo, think about image enhanced reports, telepathology, externalizing pathology images, etc...?

This was a post on Sermo several months ago.  I thought of it recently when our group was asked to upload images into the hospital PACS for viewing by clinicians.  This would include both gross and microscopic images.  The institution provided excellent support in terms of software, upload application, training and documentation tools without a requirement to do so.  It can be done ad hoc as individual pathologists see fit for particular cases. 

For several years with different LIS and PACS systems I have made this part of my practice.  I found it useful for documentation, substantiating diagnosis, providing education to clincians and since patients may and do see their pathology reports, illustrations that may be informative if they can be explained or legends are complete.  Examples of the latter include illustrating mitoses or margins for documentating grading and staging when discussion with oncologist takes place. 

The problems, questions and concerns associated with this are numerous: what fields to select, what magnification, how many, value added, legal culpability if some action is or is not taken based on  image(s) rather than text diagnosis, cost, time and reimbursement.  Most of my colleagues always question the value added and how much effort it will add to their workload for what gain to their practice, division, department or institution.  Some get concerned that clinicians will copy images of the PACS to be used in papers and publications without due credit.  I have been doing this for years with radiology images and I have never had a radiologist mention a word.  I have even inquired if they would like to contribute and they inevitably refer me to the report and images on the PACS.  And what is the value added of uploading images of a basal cell carcinoma for a clinically suspected one or a benign diagnosis that is compatible with the clinical picture of a dermatology lesion.  I select dermatopathology cases because they seem to have the most say among clinicians whether they need it, want it, would use it, value added, legal implications since pathology is on the dermatology boards, etc..., much like discussions that take place for adding microscopic descriptions.  Can clinicians make out the microscopic description?  It is part of some if not all pathology reports depending on practice and the pathologists.  No doubt anatomic pathologists, like all specialties, like all fields, have their own personalities, concerns and "best practices".  This varies widely among anatomic pathology just in terms of number of blocks submitted, number of levels, special stains used, immunohistochemistry panels/reagents/kits, etc... and how those pathologists and practices work with clincians that utilize their services.  No 2 are alike. 

I think this post hits on this and discusses the issues amongst pathologists and clincians.  I scrubbed the Sermo IDs; most are pathologists, some are clinicians, I think you can tell which are which and get a sense of where Sermo pathologists responding to this think about these issues.

Would welcome your comments.

POSTING:

Here is what I believe is "quality pathology reporting"

1 . Micrsocroscopic description , describing salient features as to how the pathologist derived at the final diagnostic interpretation.

2 . Representative digital image(s) highlighting the salient features in the diagnosis , preferably a scanning or low power, if presentable, and/or at least an intermediate or high power view, demonstrating supportive architectural and cellular details ( this way other clinicians, GI/Derm, or pathologists may be able to review report).

3 . Availability of pathologist to show diagnostic images over the internet ( secured channel , no patient identifying information disclosed ), for immedate second opinion or review by other experts .

4 . Communication between clinician and pathologist with documentation of issues discussed on final report ( may be in a comment section ), i.e . the diagnosis of malignancy was discussed with the clinician at date and time, confirming the diagnostic impression.

We here use a high resolution digtal photomicroscope, which can easily be transferred online with still photograph or through screaming videography.

Our physicians here aprreciate this commitment to quality.  Would like to know your opinion in this regard.

COMMENTS:

I love it. Sounds exactly like what I'd prefer when reviewing a pathology report. (Especially the clinician-pathologist collaboration part)

I dont' think this is about small or large practices being eliminated, because the technology currently is affordable; if your kid can afford a cellphone to textmessage, and iphone, then your pathology department surely can afford technology that would contribute to high quality pathology practice; just my opinion

those excellent pathologists you speak of should not have a problem with others reviewing their reports. SHOW THE WORLD YOUR DIAGNOSES; DON'T HIDE THEM IN A FILE, LIKE WE HAVE DONE SINCE THE BEGINNING OF TIME, and require FEDEX and UPS to deliver slides for second opinion, of course this will still take place.

Showing the photos is a natural extension of this once the technology becomes good enough, I guess. Unlike radiology, though, what's in the photos is what we select, not the whole lesion (unless it's tiny). So there's still opportunity for bias, but it certainly would shine more sunlight on the case.

Here's a question that maybe the nonpathologists can weigh in on too -- I think with the advent of PACS on the wards, we all look at more radiology than we used to (and maybe catch things the radiologist misses from time to time). Would that happen with pathology, if microscopic images were available?

I doubt it. There isn't the exposure to path like there is for radiology.

I would love it, but the labs I've dealt with seem too busy cranking out the specimens to do this kind of in-depth interaction. Probably like everyone else, they have to run harder just to stay in place income-wise.

Some clinicians can read xray and CT images just as well as a radiologist; not the case for pathology; however, the idea here is referenced to evidence-based medicine with regards to putting a digital image on the report, that could at least reflect how the primary reviewing pathologist came up with the diagnosis as rendered; ie malignant ductal cells to call breast cancer in a pediatric patient, or bizarre lymphoid cells to call a high-grade lymphoma in a young teen; this way other reviewing pathologists be it for the patient or clinician can say, yea I can see how the diagnosis came to be rather than, TRUST ME I'M YOUR PATHOLOGIST. Well, as I have stated before, tell that to the mother of a teen fighting for her life because the pathologist called an immature, malignant teratoma, a DERMOID CYST, and delayed treatment for nearly six months.

What I usually get for a micro is "microscopic examination substantiates the above diagnosis." If I get a micro it is because the pathologist has no idea what he/she is looking at. If I had it my way I would get a copy of the slide with the report.

These seem like good ideas, but I think that the images that would be added to reports would be the same that are shown at Tumor Board. If the image is to be placed in the report, then it will end up in the patient record. This would be okay if the entire case could be placed there, but with only a solitary (or maybe 2) images to show the area representative of the diagnosis, there may not be all the factors present in the image that is in the microscopic description. The legal beagles would have ammunition then to ask where in the image is the stuff mentioned in the microscopic. The answer of 'it is only a representative image' while acceptable to us, would just give the impression of the microscopic being 'made up' in a courtroom with a good lawyer. (Not that our cases would end up being sued, but with the catchall lawsuits out there nowadays, everyone gets named and there is no reason to give ammunition to anyone.) IMHO

That has been the oldest argument,and it does not stand up, because the slides and blocks, according to CAP accreditation standards, will be maintained for review for an appropriate period of time. We are simply suggesting that representative images of the most salient diagnostic feature (not all diagnostic components) should be digitally placed on the report for electronic and permanent record filing. For instance, if you make a diagnosis of malignancy, which is a microscopic diagnosis, then show features of malignancy (i don't care about the final histological classification which can be confirmed on review of the entire slide for confirmation prior to treatment), you simply should not be able to justify a person's breast coming off with 'WORDS' only, and no other evidence-based source. Let's get modern; I am not affraid of the courts, when I use sound scientific based judgement to finalize my pathological diagnosis.

As per above, for instance with breast cancer, I include 1) picture of infiltrating malignant ducts, either in sheets, or degree of tubular formation; 2) higher power view of the nuclear morphology and, an example of mitosis; 3) the highest grade of DCIS, 4) angiolymphatic invasion and 5) lymph node status, with perinodal extension if present. A total of five pictures that generally take me 5 minutes to place on the report. I think this is representative of what the surgeon or oncologist needs to know to appropriately prognose and treat this patient.

we have a system in place that once you take the picture, the picture is automatically sent to the final pathology report and place in the appropriate position on the report.

It seems to me your immature teratoma example raises one problem that your system leaves unsolved (and no system other than peer review can solve satisfactorily). If the first pathologist only includes images of areas consistent with dermoid cyst and doesn't see, recognize or photograph the immature areas, then the images in the final report will be consistent with dermoid cyst, not immature teratoma. It's likely that a pathologist including images in her/his report will select those images from the fields s/he views as most diagnostic of her/his diagnosis.

Thus, images may help if the diagnosis is flat-out wrong/incomplete, but might not help in matters of grading, subclassifying, or finding malignant areas in a benign lesion. You only see what you see.

There are other clues in the final pathology report; like gross examination, and clinical correlation. First the gross showed a 14 cm necrotic tumor, and secondly there was a clinical suspicion that raised the possibility of malignant through xray studies, etc, that's why a frozen section was performed. But your premise is correct that it requires a complete team to assess accuracy in diagnostic reporting in any field be it pathology or radiology; that is why the clinicians have a certain duty or responsibility to challenge the pathological diagnosis when it does not correlate with the clinical impression.

I am of the mind that most of us medicine docts want the best for the patient; having said this, I don't think one, pathologist, would make up or cover up mistakes by putting normal or benign tissue on that which is obviously malignant; by the way the slide was not subtle with diagnostic features of malignancy; this was gross negligence. I want to emphasize to you in your youth, that we pathologists should never operate in a bubble.

Oh, by the way, if you know of incompetent pathologist that would do this, you can believe one thing, (s)he won't practice pathology for long; the clinical colleagues will assure this, if not the pathology community; it is a tough specialty to practice, reed, and mistakes are costly in this profession, so I hope you don't think it will be easy to make mistakes as you have aluded to above, without very serious consequence to your pathology career.

That's why in my previous comment, I advise you that when in doubt, rule IT out ; this means, when you are not sure, YOU BETTER ASK SOMEONE. Get a second opinion, or send it to an expert with a lot more experience on such pathology issues, i.e questionable whether or not IT IS MALIGNANT.

Always remember this, you can be wrong on benign lesions (SK, fibroadenoma, demoid cyst, etc), you may apppear as an unwise pathologist among our colleagues, but there is no harm done, because benign lesions DON'T KILL; however, if you are wrong about malignant diagnoses, either way, you are screwed; why? because malignancy don't go away, and eventually, if the patient is not treated and even sometimes if they are treated, malignancy WILL CAUSE DEATH TO THE PATIENT, (apart of the definition of malignant tumor)

This would be a welcome upgrade to my current service...very nice!

thanks; we just need to be persistent about bringing it into being; I think there is a push by the pathology community at large to at least include digital images on final pathology reports; hopefully, that would come to past, with eventually including a copy of the slide that would include representation of all diagnostic features to be sent to patient's clinical doctor along with the final report, if the clinician requests it at no fee to patient or doctor.

We need to be reminded that patients go all over the country for treatment, and so this would be important, in addition to monitoring quality for those who have exclusive contracts, and lack external peer review.

This kind of information sharing is one of the obvious benefits of EMR technology and where I hope we are all heading. The transition is difficult, but really quite exciting. Keep it up....I love to see this stuff!
 
How much do you think telepathology would aid in this process? I gather that images that are sent out for telepath consult would be included in the final report along with the statement about peer review (or 2nd opinion or whatever statement is used by your service). Does this sound feasable to you?

I think, albeit not accepted by the general community of pathologists, telepathology will become the standard way of doing pathology practice, particularly for very remote location, like Wyoming. Here is what I envision how telepathology consultation service could work: 1) The telepathology consultant (expert or second reviewer) is first notified by the original viewing pathologist, and a code, series of alphabet and numbers similar to a surgical pathology number (unique identifyer) is given to the consultant for future reference (i.e. slide or case identification number that also identifies the patient) which is shown to the consultant at the same time as the slide is being viewed by the consultant;2) the consultant could copy unique images from the slide, selecting representative unique diagnostic features, and adding text comments as to what was discussed and the final conclusion, ALL TO BE SAVED ON A ELECTRONIC DATABASE, at selected time interval or ad infinitum for future reference.

Example of above:
Code, unique identifying number: TP080001, identifiying the patient as "Suzie Que"
Original Pathologist: Contributor
Telepathology Consultant(s): Dr. Expert
Comment:
The features of the presented slide, as demonstrated by (selected images) are compatible with GIST; suggest correlation with CD117, ..... (other stains, or clinical studies).
Notice I included more than one(1) telepathologist/consultant for the reviewing pathologists

Before this discussion closes, I wanted to comment about a schemata as to how telepathology can be used:
Telepathology Consultant (usually affiliated with academic setting with cream of the crop, dermatopathologist, cytopathologist, hematopathologist etc.)<---------->image/videotography transferred through electronic, network database<------> field pathologist, solo or group (good generalist, good diagnostic skills, and know when to seek second opinion). Notice the double arrow to suggests reversible communication; analogous to a soldier out in the battle field calling on higher ranks/experience or expertise to give help or second opinion.

The clinicians we service wouldn't have clue as to what they were looking at if we provided a picture of the lesion on the report, and I don't believe they have any urge to learn a little microscopic pathology...that's our job. If you want to brighten up your report, then do it, but it all costs money if you print paper reports that would otherwise be produced in black and white. The images also clutter up the electronic world of data memory.

I wouldn't spend the time adding a picture(s) to the report, because our average clinician is in no position to judge my diagnosis. If I'm cited in a lawsuit, the plaintiff's counsel will have a pathologist review the glass slide (which is one reason why we keep them, folks); I wouldn't want to be cornered/limited by the photos I supplied by some sharp attorney.

I tend to focus much more on HOW the information is presented to the ordering clinician, with clear cut comments/recommendations. I've learned over the years what diagnoses will generate a phone call (and rightfully so); as such I try to clarify points of the diagnosis at the time the clinician reads the report. I tend to repeat key words like "benign" in the report, in order to avert a disaster of organ removal for a benign diagnosis that the surgeon has never heard of before. I'm probably the target of much snickering by the local docs behind closed doors for my apparent repetition, but I don't care. The studies that have come out in the pathology literature in the last few years clearly indicate that many clinicians are pretty poor at interpreting a pathology report...adding a nice color shot of the lesion I don't think will improve that.

No, but it looks cool!!!  And its better than nothing; other pathologists can review what you call cancer or not, that 's all for patient safety since patients are going all over the country for treatment, and not in little village AMERICA.; plus, electronic pathology reporting is going to replace your "black and white" printer or fax; doctors are on the go, and are not going to wait for a faxed report, when they can go to their internet site and pull off the patient report whereever they are, regardless if there is a digital image on there are not. Just my humble opinion.

I would ask how many pathologists would be willing to put their name on an "outside" case review report (as we call cases that are shipped in because the patient was diagnosed elsewhere but are recieiving treatment at our institution) based just on what was shown in a few digital pictures that were selected by the original pathology department? If the answer is no, then what is the point to add the pictures for other pathologists? Any case that will be reviewed had better be reviewed with ALL the available information (i.e., the whole set of slides), or the entire digitized slide sets (which is now possible due to the slide digitizers on the market). If nothing else, it allows the pathologist to verify the slide/case accession number prior to penning a new report. How would you verify that the picture(s) with a limited view of the slide(s) are what are really on that slide (i.e., no screw ups in plugging in the digital image into the wrong patient report)?

I am a dermatopathologist, and most of our dermatologists have specifically asked NOT to have a photomicrograph on the reports. Because dermatologists train in dermpath in their residency, they feel it holds them "liable" for the accuracy of the diagnosis.

For the dermatologist above who would like to get a slide with each report, we DO provide this service to many of our referring physicians (obviously for free). We cut an extra slide for each case and send it out to them. It is nice because if they call you to discuss a case, you can both look at a representative slide at the same time.

I would not have a problem putting my name on a consultation report based on telepathology images. The disclaimer would be included of course (The evaluation and findings noted are based on evaluation of representative digital images only. If there is concern for a more worrisome entity, slides will be required prior to further evaluation). Or something to that effect. It would not be alot different then when peer reviewing representative slides of a colon cancer. The key is to include the term representative (sections/slides/digital images/whole slide images). At least for me.

Toronto's Michener Institute adding digital slide images to EHR

The Michener Institute is adding digital laboratory slide images to the EHR
By Jerry Zeidenberg 

Toronto’s Michener Institute, an educational centre for applied health sciences, has started integrating digitized microscopy images into an Electronic Health Record system. It’s one of the first sites in the country to do this.

“Typically, you do not see digital microscopy in the health record,” commented Dr. Karim Bandali, vice provost of the Michener.

Digital slide technology has the potential of becoming a very important tool for pathologists who analyze patient samples for the presence – or absence – of serious diseases, including cancer and blood disorders. “Digital microscopy is a major piece, and integrating it into the electronic record is a major development,” said Dr. Bandali.

The incorporation of slide images into the EHR has many benefits, both for Michener as a school and for hospitals and health regions.

“It will have real value for rural areas,” said Dr. Bandali. He explained that small hospitals collect samples, but usually send them out to larger centres for analysis. Unfortunately, this can be a slow process and it can take up to a week before they receive results.

By contrast, if their lab technologists prepare slides and digitize them, using special equipment, they can be sent electronically to pathologists for viewing and analysis. “You could receive a diagnosis in 24 hours,” commented Dr. Bandali.

What’s more, just as Picture Archiving and Communication Systems (PACS) for radiological images have powerful tool sets for analyzing images, so do newly emerging computerized applications for digital microscopy.

Pathologists can make use of powerful, software-based tools such as cell counters and colour analyzers, thereby improving the accuracy of their analyses.

Another major benefit: with digital microscopy, you can display several slides on the same computer screen for comparison. That is a big improvement over traditional practice, where pathologists can view only one slide at a time.

Finally, just as with images in a PACS, physicians using digital microscopy can share images for second opinions and group consultations. Once the images are stored in an archiving system and become part of the patient’s electronic record, the images can be sent to specialists and referring physicians.

Michener’s own solution arose as part of its project to create an integrated EHR, one that consolidates lab, radiology, radiotherapy, and traditional components of a health information system so that all the parts can be easily accessed.

“We’re teaching our students how to work in the hospital of the future, so we are producing a better student,” said Dr. Bandali, adding that it mitigates the amount of time that clinicians must spend educating students once they’ve joined the healthcare workforce.

He noted that most hospitals and health regions are building EHRs right now to solve real-world problems, such as patient safety. “For example, we know that medical error in the health system usually stems from a lack of communication between care-givers, especially at the time of patient hand-offs. There is not enough collaboration.”

To combat these problems, “inter-professional collaboration is now an important theme in most hospitals,” said Dr. Bandali, who asserted that the integrated, electronic health record is critical for making sure that all healthcare professionals have quick and easy access to the information they need, when they need it.

Brad Niblett, director of information management, notes that the Michener’s EHR contains the components needed for making quick, accurate clinical decisions. Major components include a Siemens PACS and RIS, as well as a HIS, LIS and radiotherapy systems from IMPAC of Sunnyvale, Calif., a division of Swedish-based Elekta. “We’re not just building an EHR,” said Niblett. “It’s an inter-professional driven EHR that’s designed to support collaboration.”

To help start building this technological vision, Michener brought together several key partners, including Unis Lumin, a systems integrator located in Oakville, Ont., Cisco Systems, which specializes in communications, and for the digital microscopy component, Quorum Technologies Inc., of Guelph, Ont., which is a Canadian distributor for Aperio Inc., of San Diego.

Niblett said “the incorporation of digital microscopy into the curriculum and EHR represents a successful public-private-partnership opportunity between multiple organizations.”

He added that when it comes to the EHR, there are three primary objectives:

• advancing the level of integration between traditional EHR information systems;

• incorporating non-traditional systems into the EHR framework;

• and incorporating relevant emerging technologies into the overall EHR.

In order to support EHR innovation, beefing up the foundational technology (network and storage infrastructure) was essential.

The main network router was replaced with a dual core unit to facilitate effective data flow and security. In addition, the installation of a SAN (storage area network) provided not only critical data capacity, but essential security and quality of service to data residing on all systems, including digital pathology, the radiology information system, radio-therapy information system, laboratory information system, and overall hospital information system.

As well, the solution employs high-powered pipes –- fibre-optic cables link servers across the network, and data is delivered to the user’s desktop at gigabit speeds. That reduces the time required to send very large image files.

The importance of a high-capacity becomes clear when we find out just how large the images can be. A single slide can take up 1 gigabyte of space, and between five minutes to one hour to scan a single slide by the specialized Aperio scanner.

An area of interest on the slide can be reduced to 100K for transmission, but if a pathologist wants a better look, he or she may very well return to the original 1GB slide image. “The 100K image isn’t diagnostic quality, but it will identify problems,” commented Niblett. “You can then go back to the original.”

Not only will clinicians benefit from digital pathology, so will students and instructors.

By using the new system, an entire class can view and discuss the same slides, at the same time. This makes it easier for the instructor, who must otherwise work with each individual student, viewing through a microscope and pointing out various structures and problems.

“Now, if you have a unique slide, perhaps a slide that is rare and specific to one clinical site, we can share this educational experience with all our students using digital slide technology,” said Dr. Bandali, who noted that most of Michener’s laboratory classes have 16 to 25 students. He commented that a professor can display the slide in high-resolution at every workstation, and discuss the case while every student sees the same image.

Digital pathology also allows the school to create its own collection of slides, which can be accessed by students and faculty at any hour. That has already happened with the Michener’s digitized collection of over 1,000 slides.

Niblett noted that plans are afoot to work with other educational institutions to share online libraries of ‘unique cases’, thereby increasing the scope of and depth of the education they can offer.

It might be added that digital slides reduce the nervousness of students and instructors who handle traditional glass slides. “Glass slides may contain rare cases, and if they are dropped or misplaced, they are lost to us forever,” commented Dr. Bandali. That is why professors in medical laboratory science and diagnostic cytology have closely supervised their students in the past, making sure that nothing is mishandled. Going digital, however, eliminates this concern – with computerized images, there’s nothing to break. “And everyone can access them, 24/7,” said Dr. Bandali.

Niblett estimates that fewer than 1 percent of labs in Canada and the United States have implemented digital microscopy systems, and quotes a recent 2006 study by the Gartner Group, a technology market research company headquartered on the U.S.

However, given all of the benefits of this relatively new solution for diagnostic labs, especially when integrated with the EHR, many observers say the issue is when, rather than if, digital microscopy will take off.

For its part, the Michener Institute is ready for this to happen. It’s already training students to use this solution, along with many others. “It’s all part of our simulation strategy,” said Dr. Bandali. “We put students through a wide variety of simulations here before they go into clinical settings.

“So when students get into the clinical environment, we are hoping it results in a seamless transition to their clinical placements. As a result of our new curriculum and the technologies we have invested in, we hope our students are prepared to hit the ground running.”  •

The Digitation of Your Medical Records

There is widespread agreement that it's beneficial and that it could improve all aspects of medicine, but there is also much standing in the way of electronic medical records.

Computerizing medical data is an old and obvious idea. The upsides in terms of efficiency and cost have always been enormous. And yet mountains of paper and other non-electronic records continue to be generated. And those records that are electronic live on incompatible islands.

Now a series of efforts is underway across the developed world to create central databases with standardized formats for medical records. The potential advantages make some observers salivate:

- Cost reductions - Medical care in the U.S. now costs $1.9 trillion, about 16% of GDP

- A dynamic lifetime view of a patient's medical history, available to any authorized provider

- Easier epidemiological studies to compare of the incidence of symptoms and the effectiveness of medications and other treatments.

- Easier surveillance for epidemics, pandemics, and bioterror.

Many argue that such a system could allow doctors to focus more on preventive care rather than a reactive approach of treating diseases as they appear.

Many of the advantages are more mundane. When you go to a doctor or emergency room out of town, they need to take a long history and lack access to records which could be helpful -- and that's just if you're conscious. Central and standardized storage of medical records would make it easier for patients to switch providers, thus enhancing competition.

It would also provide a cost advantage for providers, who spend a fair amount of money managing paper records, especially in the face of new regulations to protect the privacy of those records.

The problem of doctors and hospitals not wanting, out of old habits, to enter data electronically is still a major one, but one that will pass with time. The real problems are cost-related.

Consider the X-ray. Only in recent years have digital X-rays begun to appear, and the machines are still quite expensive. Electronics being what they are, the cost will come down and eventually traditional X-rays, which rely on expensive materials, will become uncompetitive. But in the meantime, the average orthopedist office still has a conventional X-ray system.

Such physical records are a major hole in any attempt to make records electronic. And they are not the only ones. Even simpler devices like electrocardiographs still often generate paper records because there's no incentive to the provider to spend the money on electronic hardware.

And then there's the format question: Just because you have an electronic X-ray or EKG doesn't mean all medical software can read it. There needs to be agreement on the data formats of these items.

XML has emerged as the obvious general format for holding medical data, as it excels at interoperability between systems. Much work has been done with respect to specific formats; consider this FDA document on XML medical formats, including EKG data.

But there is no widespread agreement on such standards. Even easier standards which involve only data, such as a CBC (complete blood count), aren't clearly standardized. This is ironic because any doctor could look at any paper version and read it.

There is also the problem of privacy. In the long term, making records electronic should make it easier for them to be secured, but it also opens up new and powerful avenues for the compromise of data. People are justifiably concerned that personal information could be used to prejudice them in employment or pursuit of insurance.

Technology like electronic patient records is necessarily disruptive. It will save a lot of money and enable a lot of benefit. But it will also cost a lot of people a lot of money in the form of new software and hardware that they will need to acquire, as well as old systems they will need to leave behind. Long-honed skills and habits will also be challenged. Who can blame people for resisting? But it's just a delay. Eventually, all such records will be electronic.
