Shark Tank returns: Which GI innovations will make it to market?
BOSTON – A group of aspiring innovators appeared before a panel of experts at the 2017 AGA Tech Summit Shark Tank event to make the case for how their novel device or technology could help advance the field of gastroenterology.
“The conversation that occurs here is really the start of other conversations we hope will continue out of this room and into the future to help everyone move their device or concept forward,” Michael L. Kochman, MD, AGAF, chair of the AGA Center for GI Innovation and Technology (CGIT), which sponsors the summit, told the assembled audience of potential investors, regulatory officials, and other innovators. Dr. Kochman also served as one of the “sharks” who sought to ask fundamental questions and identify potential gaps in each business plan in an ultimate attempt to make the product better and market ready. He was joined by V. Raman Muthusamy, MD, CGIT’s incoming chair, and director of interventional endoscopy and general GI endoscopy at the University of California, Los Angeles, where he is also clinical professor of medicine in the division of digestive diseases. The panel also included Jeffrey M. Marks, MD, director of surgical endoscopy at University Hospitals Cleveland Medical Center, and Dennis McWilliams, president and chief commercial officer of Apollo Endosurgery, Inc.
Analyzing RNA biomarkers in stool samples
First to face the sharks was Erica Barnell, an MD/PhD candidate at the Washington University School of Medicine in St. Louis and the chief science officer of Geneoscopy, LLC. She and her collaborators have created a series of patent-pending methods to isolate and preserve neoplasia-associated RNA biomarkers in stool samples. The technology is expected to improve screening for colorectal cancer, which is the second leading cause of cancer-related deaths in the United States, with more than 50,000 deaths annually. The high mortality rate of colorectal cancer is due, in part, to flaws in existing methodologies to screen for the disease and because of a high rate of patient noncompliance with screening guidelines, according to Ms. Barnell.
Clinical data presented by Ms. Barnell showed that their predictive algorithms in a test population of 65 persons had 81% sensitivity and 59% specificity for detecting adenomas of all sizes. Ms. Barnell acknowledged that the specificity rate was not impressive, so she and her colleagues plan to add a fecal immunochemical test in their next round of clinical trial testing.
Among the feedback Ms. Barnell received was Dr. Kochman’s suggestion that geneoscopy would benefit from having strong head-to-head data for their novel screening procedure vs. current procedures to present to the U.S. Food and Drug Administration, which Ms. Barnell said she and her colleagues were already taking into account.
Reducing risk of repetitive motion injuries
Prosper Abitbol, MD, a gastroenterologist in private practice in Boca Raton, Fla., seeks to limit the potential for harm to the clinician who performs hundreds – or more – of colorectal screening procedures annually. The EndoFeed™ device Dr. Abitbol and his team brought to the Shark Tank panel practically eliminates the need for repetitive, coordinated wrist and thumb movements when performing a colonoscopy.
The EndoFeed™ drive mechanism moves the instruments through the channel of the endoscope’s insertion tube, making it easy to complete the necessary insertion and extraction motions in biopsies without injury from repetitive motion.
Dr. Abitbol and his team also presented the EndoReVu™, which he said increases polyp detection during screening through the use of a mirror that is inserted through the instrument channel of the scope, and then provides reflective images with existing endoscope optics. The mirror is flexible to ensure there is no damage to surrounding tissue. Both devices presented by Dr. Abitbol are single use and disposable.
He concluded his presentation to the panel by saying, “I spend most of my day in the endoscopy suite every day, and I know what I need to do a better job ... I see [what] the reactions of other doctors and nurses are to this product, and I have no doubt these two products will play a major role in the endoscopy suite.”
However, while Dr. Abitbol was commended for considering the problem of operator fatigue in colonoscopies – something at least one audience member said was too often overlooked – the panel unanimously agreed that for Dr. Abitbol to move his products forward he would need to conduct some rigorous studies to show conclusive data that they improve levels of fatigue.
Identifying, classifying small polyps during a procedure
A vexing problem for clinicians is what to do after detecting a colonic polyp, since the majority of those found are not precancerous. Now, Rizkullah “Ray” Dogum, an MS/MBA candidate, and his colleagues are seeking to market a technology that reads the information gathered by elastic scattering spectroscopy to determine whether a sample is dysplastic, essentially creating the first in vivo definitive polyp classification method.
“Using elastic scattering spectroscopy technology, polyps with negligible malignant potential are detected and classified during the procedure, circumventing the routine track to pathology labs,” Mr. Dogum explained in an interview, noting that this adds up to hundreds of millions of dollars savings per year. An important fact, he said, since as our population ages it requires more screening. “As much as $1 billion could be saved annually if diminutive polyps could simply be diagnosed, resected, and discarded in lieu of histopathological processing,” Mr. Dogum said.
Currently being tested in several clinical trials that so far are yielding what Mr. Dogum says are “promising” results, especially when compared with chromoendoscopy and narrow-band imaging, the patented technology uses a white light that is transmitted through fiber optic cables that are integrated into both the snare and forceps tools; the back-reflection is detected by a computer, making polyp classification possible.
An advantage in practice for using the technology is that it does not require any significant alteration in the current standard practice for colonoscopy and does not disrupt the standard flow of work, meaning there is less training required, according to Mr. Dogum.
An audience member who identified himself as a regulator with the FDA told Mr. Dogum that over the years the agency has “struggled” with how to classify imaging technologies, because they are tools, but do not actually change practice, noting that whether to resect and discard is a clinical decision made at the physician’s discretion, not one determined by a device. He expressed his skepticism that the product would qualify as a Class II device but did suggest that it might qualify as a low-risk, de novo product, something that Mr. Dogum said in an interview following the presentation that he and his collaborators would be interested in pursuing.
Preventing endoscopic retrograde infections
Mining Big Data for algorithms that can detect endoscopic infection clusters is what Susan Hutfless, PhD, an epidemiologist and assistant professor in the division of gastroenterology and hepatology at Johns Hopkins University in Baltimore, told the shark panel she and her collaborators want to do using Medicare and Medicaid claims.
“Using Medicare and Medicaid billing data, our technology identifies endoscopic errors in a succinct and quantitative way,” Dr. Hutfless said in an interview. She explained that this benefits device manufacturers, health care facilities, and insurers. Included on the as-yet unnamed software program’s dashboard are a range of metrics that allows continuous monitoring of care, risk factors, and sources of infection, all to prevent serious outbreaks and the proliferation of illness.
Dr. Hutfless and her team came upon the idea after a string of deadly endoscope-related infectious outbreaks were linked to closed-channel duodenoscopes.
“We think that our technology helps move the field forward, because it provides a solution to contain endoscopically transmitted infections without re-engineering the endoscope,” Dr. Hutfless said. “For instance, there was an outbreak despite the use of a redesigned scope. Our technology is able to identify gaps in the care pathway that include the endoscope itself as well as the possible human factors that may be playing a role.”
Another plus, she told the panel, is that the product would not require FDA approval.
Despite data Dr. Hutfless said she and her collaborators will be presenting later this year at the annual Digestive Disease Week(R) that show a tight correlation between relevant claims data and data collected by the FDA during the infection outbreaks, the panel concluded that the stronger marketing potential for this product would be as a monitoring system, not a predictive one, used in combination with an engineering solution.
Simplifying LED incorporation in scopes
LED is only the fourth lighting technology ever invented, according to Thomas V. Root, president and CEO of Acera Inc. In an interview, Mr. Root said that while LEDs are “overtaking all major lighting markets,” medical device manufacturers have been slow to catch on.
“Acera moves the industry ahead with its elliptical optic that significantly improves the collection efficiency and distribution of the LED light. This optic, provided in a modular assembly, simplifies incorporation of LEDs in the practice of scope design and manufacture,” he said.
By eliminating the light guide tether, the use of LED increases mobility and the potential for low-cost or even single-use devices, Mr. Root said. “The result is that engineers are liberated to reimagine how endoscopes are designed.”
Because half of fires that occur in the endoscopy setting come from malfunctioning light sources, one of the sharks suggested that since the Acera product does not use the infrared wavelengths in its light, and its electrical cord remains cool to the touch while in use, Mr. Root and his colleagues should highlight that as a unique safety feature in their marketing materials.

Mortality rate was 10-fold higher in opioid use disorder patients
Individuals with opioid use disorder had a 10-fold higher mortality rate than the general population in a general health care setting, according to a study of 2,576 patients.
When researchers examined the electronic health records of opioid use disorder patients in a large university health system and linked those with mortality data, they found those patients had a standardized mortality ratio of 10.3, compared with the general population and adjusted for sex and age (J Addict Med. 2017 Apr 20. doi: 10.1097/ADM.0000000000000312).
Hepatitis C infection and alcohol use disorder were the two mostly clinically important indicators of overall mortality risk; however, none of the factors examined was a predictor of drug-related deaths.
Patients who died were also more likely to have been diagnosed with other substance use disorders, such as tobacco, alcohol, cannabis, or cocaine, and to have comorbidities such as heart disease, respiratory disease, hepatitis C infection, liver disease, cancer, or diabetes. The most common cause of death was drug-related – including poisoning, overdose, and alcohol and drug disorder – followed by cardiovascular disease, cancer, and infectious diseases such as hepatitis C.
Yih-Ing Hser, PhD, of the University of California, Los Angeles, and her coauthors called the elevated mortality rates in that group “alarming,” and suggested the rates may be the result of issues that health care systems have in identifying and addressing opioid use disorder problems.
“First, SUDs [substance use disorders] are not routinely screened for in primary care, and most primary care physicians have not received adequate training to diagnose and treat OUD [opioid use disorder],” the authors wrote. “It is likely that patients seen in this health system became progressively sicker, as their OUD problem was not identified until very late in its course and after physical health complications had already ensued.”
Second, patients with opioid use disorder may not be getting referrals for treatment. Finally, those who have problems with prescription opioids may be harder to identify than patients with heroin addiction.
“The alarmingly high morbidity and mortality among OUD patients revealed in the present study challenge health care systems to find new and innovative ways to expand evidence-based strategies for OUD in a variety of settings,” the investigators concluded.
The study was partly supported by the National Institute on Drug Abuse and the National Center for Advancing Translational Science. One author declared royalties as a section editor for UpToDate. No other conflicts of interest were declared.
Everyone is trying to respond to the opioid abuse and overdose crisis with the tools available. However, while medication-assisted therapies have been used successfully by addiction medicine and addiction psychiatry experts and programs as part of an overall program of recovery, their use as stand-alone substitution treatments has expanded.
These new data, like other recent data on emergency department interventions, strongly suggest that these treatments are limited in efficacy, and longer-term outcome studies, typical in medical oncology and physician addiction, are needed.

“First, SUDs [substance use disorders] are not routinely screened for in primary care, and most primary care physicians have not received adequate training to diagnose and treat OUD [opioid use disorder],” the authors wrote. “It is likely that patients seen in this health system became progressively sicker, as their OUD problem was not identified until very late in its course and after physical health complications had already ensued.”
Second, patients with opioid use disorder may not be getting referrals for treatment. Finally, those who have problems with prescription opioids may be harder to identify than patients with heroin addiction.
“The alarmingly high morbidity and mortality among OUD patients revealed in the present study challenge health care systems to find new and innovative ways to expand evidence-based strategies for OUD in a variety of settings,” the investigators concluded.

Key clinical point: Individuals with opioid use disorder have a significantly higher mortality rate than the general population, particularly those with hepatitis C infection or alcohol use disorder.
Major finding: Patients with opioid use disorder had a standardized mortality ratio of 10.3, compared with the general population.
Data source: A cohort study in 2,576 opioid use disorder patients.

Rotavirus vaccination in last decade cuts AGE hospitalization
There have been important reductions in hospitalization for acute gastroenteritis (AGE) and mortality since licensure of rotavirus vaccines 10 years ago, even in low-income countries with high child mortality, according to a new analysis of data from 27 countries.
In a search of articles published between Jan. 1, 2006, and Dec. 6, 2016, in the PubMed database, Eleanor Burnett of the division of viral diseases at the National Center for Immunization and Respiratory Diseases, Atlanta, and her associates identified 57 articles reporting on 59 data sources from 27 countries.
Among children younger than 5 years, the median percent reduction in AGE hospitalizations and/or ED visits was 38% overall, and 41%, 30%, and 46% in countries with low, medium, and high child mortality, respectively.
The median reduction in AGE mortality among children younger than 1 year was 31% overall. In countries with medium and high child mortality, it was 45% and 30%, respectively.
The median reduction in AGE mortality in children younger than 5 years was 42% overall. In countries with medium and high child mortality, it was 50% and 36%, respectively. No estimates have been published from countries with low child mortality (J Infect Dis. 2017 Apr 18. doi: 10.1093/infdis/jix186).
“In several, but not all studies, we observed reductions in rotavirus and AGE hospitalizations in age groups explicitly not eligible for vaccination, indicating evidence of indirect protection,” Ms. Burnett and her associates said. This population was not directly assessed in the studies.
The authors had no funding or conflicts of interest to disclose.
Decisions to introduce a new vaccine into a number of national immunization programs are influenced by many factors, including local disease burden, vaccine efficacy and safety, and the cost-effectiveness of the vaccines.
Introduction of rotavirus vaccination never started in earnest in Asia, a region with large birth cohort countries carrying substantial disease, but that lack has now turned an important corner, with India, Pakistan, and Bangladesh implementing or planning to implement rotavirus vaccination.
Also, two large African countries with high rotavirus mortality, Nigeria and Democratic Republic of Congo, are approved for Gavi (the Vaccine Alliance) funding to introduce the vaccines in 2018. The dramatic impact of rotavirus vaccines on rotavirus-associated hospitalizations and deaths described by Burnett et al. support the decisions by these large countries with high rotavirus mortality to introduce rotavirus vaccines and will lead to greater global health impacts.
Countries considering rotavirus vaccine introduction now will increasingly have additional data on vaccine safety and effectiveness. Burnett and her colleagues’ review will likely provide important information to these national immunization technical advisory groups and other decision-making bodies. This review will also be important for the earlier-adopter countries by way of validating their earlier introduction decisions.
Finally, the information will be of value to Gavi, UNICEF, and other international bodies tasked with providing resources and support for rotavirus vaccine introduction in low-income and lower-middle income countries.
Anthony Nelson, MD , is in the department of paediatrics at the Chinese University of Hong Kong, and Duncan Steele, PhD, is at the Bill & Melinda Gates Foundation, Seattle.

AAP policy addresses nonemergency acute care when it’s not the medical home
The American Academy of Pediatrics’ new policy statement affirms that the medical home is the best location for nonemergency acute care but realizes that parents may take their children to other acute care services because of access, after-hours timing, or other reasons.
The AAP encourages its members to make the medical home available as “the first point of contact for acute care” by offering “enhanced access scheduling, extended hours, and telehealth incorporated inside the medical home.” Also, the AAP “supports innovation, peer-to-peer collaboration, and practice change to promote high-quality and accessible care for all children,” the policy states.
The policy, authored by Gregory P. Conners, MD, chairperson of the AAP Committee on Practice and Ambulatory Medicine, further outlines recommendations for acute care entities serving infants, children, and adolescents outside the medical home, such as maximizing continuity of care by quickly communicating information to the medical home, as well as referring the child for necessary follow-up.
Another recommendation is to have clearly defined scope-of-service limits that are transparent to families.
Other AAP entities involved in developing the policy were the Committee on Pediatric Emergency Medicine, the Section on Telehealth Care Executive Committee, the Task Force on Pediatric Practice Change, and the Section on Emergency Medicine Executive Committee.

Dose Titration May Reduce Risk of ARIA Associated With Aducanumab
BOSTON—Compared with fixed dosing, dose titration appears to reduce the risk of amyloid-related imaging abnormalities (ARIA) associated with aducanumab, according to research presented at the 69th Annual Meeting of the American Academy of Neurology. The drug also may reduce the burden of amyloid plaques and slow cognitive decline.
Aducanumab is a human anti-amyloid beta monoclonal antibody under investigation for early Alzheimer’s disease. In an interim analysis of the PRIME study, dose- and APOE ε4-dependent ARIA of the edema type was the main safety and tolerability finding. Ahmed Enayetallah, MD, PhD, of Biogen, and colleagues investigated whether dose titration would reduce the incidence of ARIA, compared with fixed dosing.
In a double-blind, placebo-controlled study, the researchers randomized participants with prodromal or mild Alzheimer’s disease 3:1 to fixed doses of aducanumab or placebo every four weeks for 52 weeks, stratified by APOE ε4 status. After the enrollment of this cohort, the investigators added a cohort of APOE ε4 carriers who received titrated aducanumab or placebo. Patients assigned to aducanumab received two 1-mg/kg doses, four 3-mg/kg doses, five 6-mg/kg doses, and 10-mg/kg doses thereafter.
The trial’s primary end points were safety and tolerability. Exploratory efficacy end points included amyloid beta reduction by PET at one year, Clinical Dementia Rating–Sum of Boxes (CDR–SB), and Mini-Mental State Examination (MMSE).
A total of 196 patients were dosed in the study, and the titration cohort included 31 participants. The treatment groups were well balanced. Compared with placebo, titrated aducanumab was associated with significant decreases in brain amyloid beta at 12 months. The adjusted mean change from baseline in PET standard uptake value ratio was –0.171 versus 0.014, respectively. The difference was observable at week 26 and was maintained to week 54.
Titrated aducanumab also was associated with a slowing of clinical decline on CDR–SB and MMSE. Results in the titration cohort were generally consistent with those reported in fixed-dose cohorts. The incidence of ARIA was lower with titrated dosing versus higher fixed dosing of aducanumab in APOE ε4 carriers. The researchers did not find any new safety signals in the titration cohort during the placebo-controlled period.
Biogen funded the study.

Just over half of ob.gyns. accept Medicaid
Medicaid acceptance was nearly 55% among ob.gyns. in the 2017 edition of an ongoing survey conducted in 15 large cities by physician recruitment firm Merritt Hawkins.
It was up from almost 46% in the previous survey, conducted in 2014, but lower than the average of 68% for ob.gyns. in 15 midsized cities that were included for the first time in 2017, the company reported.
There were two large cities with Medicaid acceptance rates of 100% – Boston and Minneapolis (up from 40% in 2014) – along with four midsized cities – Billings, Mt.; Fargo, N.D.; Fort Smith, Ark.; and Yakima, Wash. The lowest rate among the large cities was in Dallas (15%), with the midsized basement occupied by Lafayette, La., at 10%, Merritt Hawkins said.
Investigators called 286 randomly selected ob.gyns. in the large cities and 100 ob.gyns. in the midsized cities in January and February. It was the fourth such survey the company has conducted since 2004.
The survey also included four other specialties – cardiology, dermatology, family medicine, and orthopedic surgery. The Medicaid acceptance rate for all 1,414 physicians in all five specialties in the 15 large cities was 53%, and the average rate for all specialties in the midsized cities was 60% for the 494 offices surveyed, the company said.
Cardiology had the highest rates by specialty and dermatology the lowest in both the large and midsized cities. For all five specialties combined, Fargo (100%) and Minneapolis (97%) had the highest acceptance rates, and Dallas (17%) and Lafayette (11%) had the lowest, the report showed.

Bezlotoxumab for prevention of recurrent Clostridium difficile infection
Clinical question: Does administration of monoclonal antibodies to C. difficile toxins A and B, in addition to standard-of-care antibiotics, prevent recurrent infection?
Background: Currently, no therapy has been approved to prevent recurrent C. difficile infection. A new approach to the prevention of recurrent C. difficile infection is the administration of monoclonal antibodies against C. difficile toxins (in addition to antibiotic therapy) as a form of passive immunity. Actoxumab and bezlotoxumab are fully human monoclonal antibodies that bind and neutralize C. difficile toxins A and B, respectively. In humans, the level of circulating antibodies against toxin A or toxin B has been correlated with protection against primary and recurrent C. difficile infection.
Study design: Two (MODIFY [MK-6072 and MK-3415A in Participants Receiving Antibiotic Therapy for Clostridium Difficile Infection] I and MODIFY II) double-blind, randomized, placebo-controlled, phase III trials.
Setting: 322 sites (~68% inpatient) in 30 countries from Nov. 1, 2011, through May 22, 2015.
Synopsis: Trials pooled data from 2,174 adults who were receiving oral standard-of-care antibiotics for primary or recurrent C. difficile infections. Participants received an infusion of either bezlotoxumab, actoxumab plus bezlotoxumab, or placebo for MODIFY II; actoxumab alone was also given in MODIFY I. The primary endpoint was recurrent infection within 12 weeks.
The rate of recurrent C. difficile infection was significantly lower with bezlotoxumab alone than with placebo (MODIFY I: 17% vs. 28%; 95% CI, −15.9 to −4.3; P less than .001; MODIFY II: 16% vs. 26%; 95% CI, −15.5 to −4.3; P less than .001) and was significantly lower with actoxumab plus bezlotoxumab than with placebo (MODIFY I: 16% vs. 28%; 95% CI, −17.4 to −5.9; P less than .001; MODIFY II: 15% vs. 26%; 95% CI, −16.4 to −5.1; P less than .001).
The serious adverse events were similar with most groups, the exception being actoxumab alone. Given the higher rate of recurrent infection and deaths in the actoxumab group from interim analysis, the enrollment was discontinued in MODIFY I.
Investigators did admit that safety assessments were limited because of the relatively small number of patients who received bezlotoxumab, making it difficult to detect potentially serious but low-frequency toxic effects.
Bottom line: In patients receiving oral standard-of-care antibiotics for primary or recurrent C. difficile infection, a single intravenous infusion of bezlotoxumab was associated with a significantly lower rate of recurrent infection than placebo and had a safety profile similar to that of placebo.

The rate of recurrent C. difficile infection was significantly lower with bezlotoxumab alone than with placebo (MODIFY I: 17% vs. 28%; 95% CI, −15.9 to −4.3; P less than .001; MODIFY II: 16% vs. 26%; 95% CI, −15.5 to −4.3; P less than .001) and was significantly lower with actoxumab plus bezlotoxumab than with placebo (MODIFY I: 16% vs. 28%; 95% CI, −17.4 to −5.9; P less than .001; MODIFY II: 15% vs. 26%; 95% CI, −16.4 to −5.1; P less than .001).
The serious adverse events were similar with most groups, the exception being actoxumab alone. Given the higher rate of recurrent infection and deaths in the actoxumab group from interim analysis, the enrollment was discontinued in MODIFY I.
Investigators did admit that safety assessments were limited because of the relatively small number of patients who received bezlotoxumab, making it difficult to detect potentially serious but low-frequency toxic effects.
Bottom line: In patients receiving oral standard-of-care antibiotics for primary or recurrent C. difficile infection, a single intravenous infusion of bezlotoxumab was associated with a significantly lower rate of recurrent infection than placebo and had a safety profile similar to that of placebo.

Clinical question: Does administration of monoclonal antibodies to C. difficile toxins A and B, in addition to standard-of-care antibiotics, prevent recurrent infection?
Background: Currently, no therapy has been approved to prevent recurrent C. difficile infection. A new approach to the prevention of recurrent C. difficile infection is the administration of monoclonal antibodies against C. difficile toxins (in addition to antibiotic therapy) as a form of passive immunity. Actoxumab and bezlotoxumab are fully human monoclonal antibodies that bind and neutralize C. difficile toxins A and B, respectively. In humans, the level of circulating antibodies against toxin A or toxin B has been correlated with protection against primary and recurrent C. difficile infection.
Study design: Two (MODIFY [MK-6072 and MK-3415A in Participants Receiving Antibiotic Therapy for Clostridium Difficile Infection] I and MODIFY II) double-blind, randomized, placebo-controlled, phase III trials.
Setting: 322 sites (~68% inpatient) in 30 countries from Nov. 1, 2011, through May 22, 2015.
Synopsis: Trials pooled data from 2,174 adults who were receiving oral standard-of-care antibiotics for primary or recurrent C. difficile infections. Participants received an infusion of either bezlotoxumab, actoxumab plus bezlotoxumab, or placebo for MODIFY II; actoxumab alone was also given in MODIFY I. The primary endpoint was recurrent infection within 12 weeks.
The rate of recurrent C. difficile infection was significantly lower with bezlotoxumab alone than with placebo (MODIFY I: 17% vs. 28%; 95% CI, −15.9 to −4.3; P less than .001; MODIFY II: 16% vs. 26%; 95% CI, −15.5 to −4.3; P less than .001) and was significantly lower with actoxumab plus bezlotoxumab than with placebo (MODIFY I: 16% vs. 28%; 95% CI, −17.4 to −5.9; P less than .001; MODIFY II: 15% vs. 26%; 95% CI, −16.4 to −5.1; P less than .001).

HHS Secretary Price promises reduced health IT burden for physicians
WASHINGTON – Reducing IT burden for doctors and fostering interoperability are two top tech priorities for Health and Human Services Secretary Tom Price, MD.
“We simply have to do a better job of reducing the burden of health IT on physicians and all health care providers,” Dr. Price said April 27 at Health Datapalooza, an annual conference on health data transparency. “The promise of big data and health information technology is so great and absolutely remarkable but we must not, we cannot continue to get this wrong.”
“Now we are seeing physicians leaving the practice of medicine when they are 60 or 55,” he said. “Many of my colleagues, my personal friends who have been practicing, right now they are looking for the exit doors. They are trying to figure out how to get out of practicing medicine and I think it is incredibly important for us as a society to step back and ask, why?”
A significant factor is the shift to electronic health records, which has caused doctors to spend much more time looking at screens and feeling more like data entry clerks than health care providers, he said.
“I know that we have lost more than one physician to retirement because of the kinds of burdens that have been placed on a lot of them and that simply ought to be unacceptable to us,” he said. “You think of the intellectual capital that has been lost by this nation because of the kinds of burdens that clinicians have seen.”
That said, “data is absolutely crucial,” Dr. Price said. “Don’t misunderstand me. It is absolutely critical that we have all the data that we can and that we use it in an evidence-based manner so that we can provide better care and better quality of care to patients.”
He challenged the health IT professionals at the meeting to make their products more user friendly.
“We will work on reducing the burdens at the federal level, but we also need clinicians and IT folks on the ground to help make certain that technology implementation is done in a way that it enhances usability and increases efficiency,” Dr. Price said.
He also called for true interoperability, a common goal that has persisted since electronic health records were mandated under the HITECH Act but remains an elusive target.
“This has always been the goal and it just seems so simple,” he said. “Somehow something has happened between the idea of interoperability and now that has made it so much more challenging.”
He placed that fault on current federal regulation around interoperability and pledged to create an environment that reduces regulatory roadblocks and allows the technology sector to innovate and foster the free flow of data.
“From my perspective it seems that what we ought to be doing is deciding the rules of the road,” Dr. Price said. “We are going to drive on the right side. We are going to stop at the red light. This is the language we are going to do. This is what a triangular sign looks like, as opposed to stipulating every single dot... all the way down the line.”

AT HEALTH DATAPALOOZA 2017
Hospitalists: Leading health care innovation
As I begin my year as SHM president, I continue to be energized by the opportunity to be part of an organization that has such a positive impact on our nation’s health care system. From the beginning of my medical career to now, never have I witnessed a health care movement quite like hospital medicine.
Even when I first arrived in Southern California as a pulmonary/critical-care physician in 1987, there were groups of physicians who had taken financial risk on populations of managed-care patients and were paid using an “alternative payment model” called capitation. One of the innovations they had utilized since the early ’80s to successfully manage their risk – and their patients’ – was to have dedicated inpatient physicians caring for their hospitalized patients 24/7, while most of their primary care partners managed the group’s patients in the outpatient setting.
This year will see a continued reshaping of our delivery system, driven by emerging federal policy like the Medicare Access and CHIP Reauthorization Act (MACRA). All of this policy is designed to create a health care system that delivers high-quality care in a much more cost effective way. Many of these policies will result in groups of providers being pushed away from fee-for-service payment toward alternative payment models that involve higher levels of risk and opportunity. If we, as providers, are going to be successful in managing our “at risk” populations, we are going to have to be as innovative as our managed care forefathers. If we are not, we, as a society, are not going to be able to afford to deliver high-quality care to our nations sickest citizens.
At the center of much of this innovation will be hospitalists. After all, by its very nature, our model is a delivery system reform. The drive to deliver more-efficient quality care is in the very DNA of our specialty.
As decisions are made, they will have a significant impact on our patients and our careers. It will continue to be a priority for SHM to make sure that the voice of hospital medicine is heard loud and clear. We will continue to ask our members to ensure that the hospital medicine community has a prominent place in these conversations. Those who step up in this effort will lead us as we insist on having a prominent seat at the table and as new models of care emerge and new incentives are created for the provider community. We will continue to strive to make sure that our patients get the care they deserve and that we continue to help build a sustainable health care delivery system.
This year, you will also see a focused effort to strengthen SHM’s system of state and local chapters. The vitality of these local organizations is important to our efforts to effectively serve our members by engaging them with their colleagues at the local level. In our attempts to further connect our members with others who share similar interests and focuses, we will be rolling out a new structure of special interest groups. These local chapters and these interest groups will fuel new ideas that will continue to improve our specialty and the effectiveness of the society to speak for hospital medicine with a strong voice.
Of course, SHM will continue to be the only organization that was created to represent our nation’s hospitalists and will be totally committed to providing our members with clinical and administrative education, dedicated publications, leadership training, research opportunities, and advocacy. I look forward to serving you and helping you get the most from your SHM experience. Together, we will continue to move the hospital medicine movement forward, shaping our health care system and improving patient care.

Study Reveals Tumor Blood Vessels Cluster in Beltlike Zones
Digital pathology has made it possible to measure microscopic objects, such as blood vessels in tumor tissue and then visualize them in density maps, showing hotspot regions. But for many applications in histopathology, there is no clear-cut definition of the hotspots, say researchers from Heidelberg University in Germany. Thus, most tumor models “implicitly assume” that blood vessels are equally abundant in different parts of a tumor. But the researchers’ new computational approach to mapping angiogenesis in colorectal cancer (CRC) could change that assumption.
Related: In Rare Case Colorectal Cancer Causes Thrombus
Their method analyzes blood vessels based on spatial statistics, identifying all hotspot areas that are unlikely to occur by chance. The researchers found that in nearly all cases, the blood vessels grouped in a distinctive beltlike pattern. In 33 of 34 untreated colorectal tumor samples, the blood vessels were aggregated at the interface of tumor tissue to the intestinal wall. The researchers found similar “hypervascularized” zones at the boundaries of liver tissue in 100% of the samples of CRC liver metastases. Ultimately, they describe a new model of tumor vascularization: a highly vascularized zone about 1.5-mm wide close to the intestinal lumen in CRC primary tumors and a highly vascularized zone approximately 1-mm wide close to the invasion front in CRC liver metastases.
Related: Colorectal Screening: Available but Underused
Their model has immediate and far-reaching implications, the researchers say. For instance, because vascular patterns determine how chemotherapeutic drugs are distributed in tumor tissue, it is likely that these drugs reach the luminal side of CRC tumors much easier than they reach the the basolateral side. Their new information also could be used in timing surgery, since the tumor parts of the deep invasion front may be less sensitive to chemotherapy. The researchers suggest that using their model could help optimize treatment in any number of ways: explaining early symptoms like gastrointestinal bleeding, the architecture of CRC, metastasis, and opening new pathways for investigation.
