How does the CHC America model benefit Payors?

There are three main reasons that the CHC America model benefits payors: Convenience, Cost, and Quality:

Convenience. The CHC America CRC screening process represents the ultimate in patient convenience, comprehensiveness, and safety. The patent-pending CHC America process brings together the best aspects of Virtual Colonoscopy/CT Colonography (CTC) and Traditional Colonoscopy, and minimizes the limitations of both, in a way that cannot be replicated elsewhere.

The majority of average risk patients (approx. 75%) who present for screening will not be found to have colon polyps or other abnormalities that would need to be removed. It is unfortunate that, today, these patients have to undergo the additional risk and inconvenience of a traditional colonoscopy, only to find a "clean" colon. On the other hand, 25% of patients will have polyps and early cancers detected on CTC that will need to be removed. It is unfortunate that these patients need to undergo a colon prep for the CTC, and later will be notified that they will have to 1) schedule an appointment for a traditional colonoscopy to remove the abnormalities, and 2) undergo a second colon prep all over again! These patients have every right to be angry!

The CHC America process streamlines and eliminates these problems by creating a "Colon Health Center"--a CTC imaging center together with traditional colonoscopy endoscopy center.

Patients arrive at the Colon Health Center after an overnight colon prep. They receive their CTC, which takes approximately 15 minutes. The CTC images will be immediately sent to the CHC America reading site, staffed by the most expert CTC readers in the country. Within one hour's time, the patient's CTC reading will return and the patient will be notified whether or not they have any abnormalities. If they are one of the lucky 75% of average risk individuals, they are done and can immediately resume all activities.

If they are among the 25% of individuals with polyps or other abnormalities, they will be immediately directed to the co-located endoscopy center where they will undergo a traditional colonoscopy and remove the abnormalities.

No need for a second prep! No second day off work! Pure convenience designed around the needs of patients.

Cost. The CHC America model is a highly efficient way to do "whole bowel" screening for large populations. Because CHC America uses a two-step approach to CRC screening--employing the more cost-effective CTC first, and then following up with a same-day therapeutic colonoscopy in only those who need it--the CHC America model costs significantly less than the current standard care:  traditional colonoscopy for all. With an approximate 45% difference in cost, the CHC America allows payors to screen many more members for the same cost expended today.

Further, CHC America offers an opportunity for payors to bundle the entire "screening event" into one blended reimbursement, providing cost predictability on a per patient basis. With a bundled reimbursement, members receive a complete and comprehensive colon screen, tailored to their needs (CTC +/- therapeutic colonoscopy) for one predictable price. Great for patients, great for payors.

Why pay 45% more for yesterday's standard of care, when you can provide members the highest quality, most technologically advanced, convenient, and patient-centric screening process available at a CHC America Colon Health Center!

Quality. Recent studies of CTC show that it is as sensitive for detecting polyps and cancers as traditional colonoscopy. In fact, in many ways, the images provided by CTC are even better than those seen by traditional colonoscopy. This is because CTC can often see polyps behind haustral folds easier and better than traditional colonoscopy.

The best studies have been shown in programs with consistent equipment types, image processing software, reading techniques, and reader training. Pickhardt, et al. performed a multi-center trial of CTC as a screening method for CRC in over 1233 asymptomatic, average risk patients. They maintained a uniformity of training, scanning, and reading techniques. The study authors used strategy using 3-D endoluminal displays as the primary reading source, with clarification and problem-solving in 2-D windows.

CHC America's process includes the use of the latest, most standardized equipment and techniques for reading CTC. We also use a centralized CTC reading approach, which allows for a high level of quality assurance with the readings.

What is Virtual Colonoscopy/CT Colonography (CTC)?

CTC is a revolutionary and technologically-advanced new screening test for CRC.  CTC is an imaging test that is performed by an advanced CT scanner. Images of the patient's abdomen are taken by the CT scanner. With special software, these images are put together to create a three-dimensional image of the colon. This 3-D image of the colon provides the same view of the inside of the colon that is seen by traditional colonoscopy. In fact, the views provided by CTC, in many ways, are even better than those seen by traditional colonoscopy.

Why is CT Colonography (CTC) such a breakthrough screening test?

CTC is a non-invasive test. It does not require the insertion of an endoscope throughout the colon. It is quick--completed in about 10-15 minutes. Further, it does not require sedation or anesthesia. Therefore the patient is able to immediately resume all activities, including driving and work.

Recent studies of CTC show that it is as sensitive for detecting significant polyps and cancers as traditional colonoscopy. In fact, in many ways, the images provided by CTC are even better than those seen by traditional colonoscopy. This is because CTC can often see polyps behind haustral folds of the bowel easier and better than traditional colonoscopy.

Furthermore, unlike traditional colonoscopy, which only sees the inside of the colon, a CTC also provides images of the rest of the abdomen. While CTC images are not a substitute for a complete abdominal CT scan, if one is indicated, these CTC images often detect early cancers and other abnormalities in abdominal organs. Many people have been cured of asymptomatic abdominal cancers because they were detected early by CTC.

With CTC, patients not only receive a very sensitive screening test for CRC, but they also get a chance to detect any other early cancers that might be present in the abdomen.

What do the research studies show for CTC?

In past years, the results of the research studies on CTC have shown a wide range of sensitivity . There are several reasons for this wide range of sensitivity, including the use different scanning equipment, different reading protocols, different image processing techniques, and varied experience of radiologists.

The best studies have been shown in programs with consistent equipment types, image processing software, reading techniques, and reader training. Pickhardt, et al. performed a multi-center trial of CTC as a screening method for CRC in over 1233 asymptomatic, average risk patients. They maintained a uniformity of training, scanning, and reading techniques. The study authors used strategy using 3-D endoluminal displays as the primary reading source, with clarification and problem-solving in 2-D windows.

This technique resulted in a high sensitivity and specificity (93.9%, 92.2%) for CTC similar to than traditional colonoscopy. Sensitivities and specificities of CTC have continued in the research done by two of the large CTC clinical programs across the country, at the University of Wisconsin, Madison, and the Bethesda National Naval Medical Center.

The National CT Colonography Trial (ACRIN 6664) is another large, multi-center trial of the efficacy of CTC for CRC screening. The results of this study were released in Fall 2007, and validated the findings of Pickhardt, et.al. that CTC was a sensitive and accurate screening test for colorectal cancer.  See ACRIN results.

What are the major limitations of CTC?

While CTC is a powerful new technology, and a test that most patients prefer over traditional colonoscopy, there are a few limitations. First, CTC has no polyp removal capability. If polyps are detected (approximately 25% of average risk patients), a traditional colonoscopy needs to be performed to remove them.

Second, patients who undergo CTC will need to perform a 12 hour, pre-test colon preparation (laxatives), exactly like patients who undergo traditional colonoscopy.

The innovative process employed by Colon Health Centers of America greatly reduces the impact of these two limitations. The CHC America process allows patients to fully benefit from all the many advantages of CTC, while greatly reducing the impact of the two limitations. (See What is so innovative about the Colon Health Centers of America CRC screening process?)

Why choose the Colon Health Centers of America screening process over stand-alone radiology/imaging centers?

CTC is a test that is also offered at stand-alone radiology and imaging centers. But the vast majority of these centers will have no capability to follow-up with a traditional colonoscopy. Therefore, patients receiving a stand-alone CTC will be forced to take a second day off work and undergo a second colon prep! Who would want to take that risk?

Furthermore, the CTCs done at stand-alone radiology/imaging centers will likely be read by the local staff radiologist. While they may be fine radiologists, they will typically be generalists who read chest x-rays, MRIs, mammograms, ultrasounds, etc. along with CTCs. The radiologists who read CHC America studies are national experts in CTC. In many cases, CTC is all they read--all day, every day. Studies have clearly shown that experience dramatically improves one's ability to read CTCs. With CHC America, you will only have the best CTC readers in America reading your study.

Is there radiation involved in CTC?

Yes, there is radiation exposure with any x-ray or CT scan. Fortunately, with advances in CT technology the radiation exposure from is minimal and is similar to the environmental radiation exposure that one encounters by being outdoors for a period of time. Equipment used at CHC America centers is the latest technology and therefore performs CTC with the smallest possible radiation exposure.

Can patients receive a similar comprehensive, same-day process elsewhere?

The short answer is "no". CHC America has a patent pending with the US Patent and Trademark Office on their innovative and comprehensive, same-day screening methodology in the community. Furthermore, CHC America has a passion for improving patient satisfaction with its CRC screening process. After all, satisfied patients are more likely to get screened and therefore prevent colon continues to improve and perfect this patient-centered approach to CRC screening.
