    reason for todays drop UNH

    While looking at the site I saw this:

    Computed tomographic colonography is proven and medically necessary for any of the following:
    • As a diagnostic tool for symptomatic patients who are unable to undergo a complete colonoscopy (such as individuals with an obstructive tumor and others who may be unable to tolerate the procedure)
    • Patients on anticoagulation therapy who cannot safely discontinue treatment and would be at risk of bleeding from a more invasive procedure
    • As a screening test for colon cancer

    So CT colonography is OK for screening even though it wasn't recommended by USPSTF and there is no evidence it reduces the likelihood of reducing CRC mortality - the reasoning they gave for not supporting CG. Sounds political or that Exact and UNH haven't had the best of negotiations. Doesn't make much clinical sense.

    July 1 2016: form UHC provider medical policy site
    Fecal DNA testing for colorectal cancer screening and/or monitoring is unproven and not medically necessary.
    There is insufficient published evidence in the clinical literature supporting the diagnostic accuracy of fecal DNA tests to screen for colorectal cancer in asymptomatic, average-risk patients. The gold standard for colorectal cancer screening is optical colonoscopy. There is insufficient published evidence comparing fecal DNA testing to optical colonoscopy. In fact, there is insufficient published clinical evidence that fecal DNA testing reduces the likelihood of mortality from colorectal cancer
    The National Comprehensive Cancer Network (NCCN) states that emerging technologies such as stool DNA have shown increasing evidence as a reasonably accurate screening test, but there is limited data to determine the optimal testing interval. Stool DNA testing is not recommended as a primary screening modality at this time (NCCN, 2015).The U.S. Preventive Services Task Force (USPSTF) recommendation on screening for colorectal cancer (CRC) concludes that evidence remains insufficient to assess benefits or harm for fecal DNA testing as a screening modality for CRC (USPSTF, 2015).

    Very interesting that they don't include the new USPSTF guidelines in their review. This is OLD info and they will be obligated to cover in the next 12 months.

    CDC press release 6/24

    Sorry-Actually 4.7 million every 3 years (or yearly if 30% of fit market)

    CDC researchers estimate that U.S. health care facilities have the capacity to meet the National Colorectal Cancer Roundtable’s goal of screening at least 80% of adults aged 50 to 75 years for colorectal cancer by 2018.
    The model showed that if a program using FIT as the primary screening method was implemented, 47 million FITs and 5.1 million colonoscopies would be needed each year by 2024. If a program using colonoscopy as the only screening method was implemented, 11 to 13 million colonoscopies would be needed per year.

    So lets say conservatively CG could get 10% of the FIT tests in this model. I'll take 4.7 million tests a year x an average of $400+ test.

    You might be right that 240k is built in, but I don't think the street believes KC's estimates to start growing 30% quarter over quarter after the relatively flat past 3 quarters. Personally, I'd be happy to see 240K at this point.

  • marsala1234 marsala1234 Jun 9, 2016 11:59 AM Flag

    Buyer - the fact that they have maintained the 240K test expectation when the street is around 210K is in my mind guidance that testing is accelerating, because to meet 240K testing will have to hit around 150K for Q3 and Q4 combined vs 90K the first half of the year. They must have some visibility they are not specifically sharing yet. (I hope!)

  • Gastroenterology. 2016;150(2):396-405.

    Methods: We collected data from 438 men who underwent screening or surveillance colonoscopies and then repeat colonoscopy examinations within 60 days by a different blinded endoscopist (1161 colon segments total) at the West Haven Veterans Affairs Medical Center from January 2014 to February 2015. Missed polyps were defined as those detected on the second examination of patients with the best possible bowel preparation (colon segment BBPS score of 3) on the second examination.

    Results: The adjusted proportion with missed adenomas greater than 5 mm was noninferior for segments with BBPS scores of 2 (5.2%) vs those with BBPS scores of 3 (5.6%) (a difference of -0.4%; 95% confidence interval [CI], -2.9% to 2.2%). Of study subjects, 347 (79.2%) had BBPS scores of 2 or greater in all segments on the initial examination. A higher proportion of segments with BBPS scores of 1 had missed adenomas larger than 5 mm (15.9%) than segments with BBPS scores of 3 (5.6%) (a difference of 10.3%; 95% CI, 2.7%–17.9%) or 2 (5.2%) (a difference of 10.7%; 95% CI, 3.2%–18.1%). Screening and surveillance intervals based solely on the findings at the first examination would have been incorrect for 16.3% of patients with BBBPS scores of 3 in all segments, for 15.3% with BBPS scores of 2 or 3 in all segments, and for 43.5% of patients with a BBPS score of 1 in 1 or more segments.

    Conclusions: Patients with BBPS scores of 2 or 3 for all colon segments have adequate bowel preparation for the detection of adenomas larger than 5 mm and should return for screening or surveillance colonoscopy at standard guideline-recommended intervals. Colon segments with a BBPS score of 1 have a significantly higher rate of missed adenomas larger than 5 mm than segments with scores of 2 or 3. This finding supports a recommendation for early repeat colonoscopic evaluation in patients with a BBPS score of 0 or 1 in any colon segment.

    Ranjo- could be an exciting (or punishing) end of summer with a USPSTF decision and Reduce It results - good luck long timer!

  • Early results from a European trial of colonoscopy has two important lessons for the practice

    The lessons from the NordICC study, preliminary results on practical points of performing colonoscopy, were published online May 23 in JAMA Internal Medicine. (However, data on the primary end points of colorectal cancer mortality and incidence will not be available for another 8 years or so.)
    The study involved 94,959 patients identified as eligible from population registries in Norway, Poland, Sweden, and the Netherlands;
    The study showed that colonoscopy could be performed successfully without sedation, and that insufflation with carbon dioxide rather than air could significantly reduce postprocedure abdominal pain.

    2 thoughts:
    1) CG is way simpler and less painful
    2) Nordic folks and Pols are way tougher than your average American who won't go without a Propofol cocktail!!
