How pain management is evaluated in the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey is changing, thanks in part to the advocacy efforts of the Society of Hospital Medicine’s public policy committee.

Based on input from SHM and other organizations, the Centers for Medicare & Medicaid Services decided that the way the survey was worded concerning pain management could be leading to unintended consequences, particularly in light of the opioid epidemic.

In a video interview recorded during HM17, John Biebelhausen, MD, MBA, discussed how SHM worked with the CMS to help “improve the HCAHPS survey to make a better patient satisfaction tool for our assessments and also eliminate some of the competing pressures the physician might face.”

What are some of the most common interruptions physicians face, and what simple solutions exist to help minimize the breaks in workflow?

Physicians are interrupted, on average, 15 times an hour, according to Roberta Himebaugh, a senior vice president at TeamHealth in Pleasanton, Calif., but as she explains in this video recorded at HM17, there are some simple, low-tech – and other – solutions that health systems can use to help hospitalists streamline workflow.

LAS VEGAS – The heavy burden of triple negative and other aggressive breast cancers among African American women cannot be simplified to socioeconomic factors alone.

International investigations by Lisa Newman, MD, director of the Breast Oncology Program at the Henry Ford Health System, Detroit, and other researchers are making it clear that genetic factors play a significant role.

She explained the latest findings and what they mean for screening, genetic referral, and treatment in an interview at the American Society of Breast Surgeons annual meeting.

LAS VEGAS – According to recent guidelines, no ink on tumor is the right surgical margin for early stage invasive breast cancer and 2 mm is the right lumpectomy margin for ductal carcinoma in situ (DCIS) treated with whole breast radiation. But, what do you do when invasive carcinoma is associated with DCIS?

It’s a common question for breast surgeons. Monica Morrow, MD, chief of breast surgery at Memorial Sloan-Kettering Cancer Center in New York City, explained how to handle the situation in a video interview at the annual meeting of the American Society of Breast Surgeons.

She was the senior author on the 2014 invasive breast cancer guidelines and the lead author on the 2016 DCIS guidelines, both of which were consensus statements on surgical margins from the Society of Surgical Oncology and other groups (Ann Surg Oncol. 2014 Mar;21[3]:704-16; Ann Surg Oncol. 2016 Nov;23[12]:3801-10).

Dr. Morrow explained the thinking behind the guidelines and how to apply them to mixed lesions and other clinical scenarios, as well as their limitations and what remains to be determined. A key point is that a margin less than 2 mm is not by itself an indication for mastectomy in DCIS.

BOSTON – The use of surgical therapy for early stage lung cancer in the United States has declined as other nonsurgical treatment options have become available, according to a study reported at the annual meeting of the American Association for Thoracic Surgery.

Most notably, the study finds that surgery for early stage non–small cell lung cancer decreased by 12% from 2004 to 2013.

In a video interview, Keith Naunheim, MD, a professor of surgery at Saint Louis University, discusses the study findings and the potential reasons behind declining surgery use for lung cancer. Dr. Naunheim also addresses why physicians should keep an open mind about alternative therapy options for lung cancer, while ensuring that the treatments are safe and effective for patients.

PARIS – Serelaxin’s failure to meet its primary endpoints in an acute heart failure trial with more than 6,500 patients, coupled with a similar failure by ularitide in the same patient population in pivotal trial results first reported in November 2016, led some experts to rethink their conception of potential interventions for patients hospitalized for acute heart failure decompensations.

“We learned in TRUE-AHF that giving a drug very early [in acute heart failure] does not prevent [long-term] death. It means that early is not early enough,” Alexandre Mebazaa, MD, said in a video interview at a meeting held by the Heart Failure Association of the European Society of Cardiology.

BOSTON – Adjunctive treatment with cannabidiol significantly reduced convulsive seizure frequency in Dravet syndrome patients in a randomized, double-blind, placebo-controlled trial.

Over a 14-week treatment period, including 2 weeks of titration and 12 weeks of maintenance, convulsive seizure frequency in 61 treated children and adolescents decreased from a median of 12.4 to 5.9 per month (median reduction of 39%), compared with a decrease from a median of 14.9 to 14.1 per month (median reduction of 13%) in 59 patients who received placebo, J. Helen Cross, MD, reported at the annual meeting of the American Academy of Neurology.

The proportion of patients with at least a 50% reduction in convulsive seizures was 42.6% with cannabidiol vs. 27.1% with placebo (odds ratio, 2.0), but this difference did not reach statistical significance, said Dr. Cross of the University College London Great Ormond Street Institute of Child Health and the Great Ormond Street Hospital for Children NHS Trust, London.

In a video interview, Dr. Cross discussed the findings and the importance of improving seizure control in patients with Dravet syndrome, a rare infantile-onset developmental and epileptic encephalopathy with very poor prognosis for long-term seizure control and neurodevelopmental outcomes.

Participants in the study (GWPCARE1) had a mean age of 10 years, but nearly a third were younger than 6 years. All had Dravet syndrome and drug-resistant seizures; the median number of antiepilepsy drugs previously tried was four, and the median number being used was three. Those randomized to the treatment group received cannabidiol oral solution up to 20 mg/kg per day.

Adverse events were common, occurring in 93.4% and 74.6% of treatment group and placebo group patients, respectively. But adverse events reported in the treatment group were mild or moderate in 84% of patients, and treatment was generally well tolerated.

“These are very complex patients with a high seizure burden... and therefore, to have another medication that looks as if it can be of benefit is really very exciting for this population,” Dr. Cross said, noting that cannabidiol was also shown in other studies presented at the AAN meeting (GWPCARE3 and GWPCARE4) to reduce seizure frequency in patients with Lennox-Gastaut syndrome.

GW Research sponsored the study. Dr. Cross is a member of the advisory boards for Eisai, GW Pharmaceuticals, Shire, and Zogenix.

BOSTON – Some of the most influential clinical research reports coming out of the annual meeting of the American Academy of Neurology raise questions on how neurologists will strike a balance between the improved efficacy and safety of drugs in new therapeutic classes and their affordability for patients.

Natalia Rost, MD, vice chair of the AAN Science Committee, discussed phase III clinical trials (ARISE and STRIVE) in episodic migraine with erenumab, an investigational humanized monoclonal antibody against calcitonin gene-related peptide receptor; phase III clinical trials (ENDEAR and CHERISH) of the antisense oligonucleotide drug nusinersen (Spinraza) that was approved by the Food and Drug Administration for spinal muscular atrophy in late 2016; as well as phase III trials of a pharmaceutical-grade extract of the cannabis-derived compound cannabidiol in patients with Dravet syndrome and Lennox-Gastaut syndrome.

Erenumab and nusinersen are “disease-specific targeted biologics” that have been developed over decades to target a specific disease pathway, and hence translate into high prices, Dr. Rost said in a video interview at the meeting.

“How you value the cost of a drug against improvement in a physiological outcome is very difficult to measure,” she noted, for relatively small gains in reducing migraine days per month and improvements in functional outcome and disability against placebo.

But this calculation is different with the potentially lifesaving effects of nusinersen for spinal muscular atrophy patients, in which “we’re not talking about days of improvement, we’re talking about days of life,” said Dr. Rost, director of acute stroke services at Massachusetts General Hospital, Boston. “And so that becomes an ethical dilemma in terms of the cost of administration, who is paying for the drug, and how this is covered. Whom do you offer treatment to?”

The development of cannabidiol as a potential adjunctive treatment for Dravet and Lennox-Gastaut syndromes is a welcome addition to the armamentarium against these conditions, Dr. Rost added, because it offers an alternative to the unregulated use of herbal medications and supplements – particularly cannabis in its various forms – that patients ask about but are difficult to dose consistently and to ensure a pharmaceutical-grade level of purity.

BOSTON – The avenues for identifying those individuals most likely to benefit from surveillance and chemoprevention of colorectal cancer (CRC) are multiplying, experts agreed at the 2017 AGA Tech Summit sponsored by the AGA Center for GI Innovation and Technology.

In a series of three consecutive presentations, the first updated efforts to improve germline genetic testing. The second identified biomarkers that appear likely to improve the risk-to-benefit ratio from aspirin in cancer prevention. The third cautioned about the potential pitfalls of genetic testing for cancer risk even though the overall effect was to highlight the value of this tool when performed appropriately.

Novel tools for germline testing

Biomarkers for GI cancer chemoprevention

Citing a long list of studies and trials that have associated aspirin with protection against CRC, including a randomized controlled trial in Lynch syndrome, Dr. Chan characterized the evidence of a chemoprotective effect from ASA against GI cancer as “overwhelming.” However, not all individuals may derive a favorable risk-to-benefit ratio due to the antiplatelet effects of ASA that increase risk of bleeding events in the GI tract and elsewhere.

The best approach to providing a favorable risk-to-benefit ratio may involve identifying biomarkers that predict benefit. The progress in understanding how ASA inhibits pathways of tumor development has provided candidates, according to Dr. Chan, citing a series of studies, including those conducted at his center.

One proof of concept was derived from work in evaluating tumor expression of cyclooxygenase (COX), the enzyme that converts arachidonic acid to prostaglandins. Dr. Chan explained that prostaglandin are linked to many downstream cancer-promoting pathways. In a study that involved molecular analysis on tumor specimens from patients who participated in a cohort study, the presence of the COX-2 isoenzyme was a differentiator.

“When the evaluation was performed according to COX-2 status, we saw about a 30% reduction in risk for COX-2-positive tumors. In contrast, we did not see any appreciable reduction in risk in tumors that were COX-2-negative,” Dr. Chan reported.

Although Dr. Chan acknowledged that about 80% of CRC tumors are COX-2-positive, which may explain why CRC protection from ASA is observed in an unselected population, he reported that this study has supported pursuit of additional biomarkers, particularly those that might predict protection from ASA before or at the very earliest stages of the neoplastic process.

One such candidate is 15-prostaglandin dehydrogenase (15-PGDH) enzyme, which is known to catabolize or breakdown prostaglandin. When 15-PDGH levels were evaluated in normal tissue samples adjacent to CRC tumors, there was about a 50% reduction in risk of CRC in those with high 15-PGDH “but there was actually no reduction in risk among those with low 15-PGDH,” Dr. Chan reported.

Currently, ASA prophylaxis for preventing CRC is recommended by the U.S. Preventive Services Task Force in individuals who also have an increased risk of cardiovascular disease, but there is no accepted formula for weighing CRC risk against risk of bleeding. Biomarkers like 15-PGDH could be instrumental in guiding decisions for gastroenterologists.

“So you can imagine a strategy in which the endoscopist removes the polyp and also takes a biopsy of adjacent normal tissue to determine whether there are sufficient levels of 15-PGDH to potentially predict whether ASA will have a preventive effect,” Dr. Chan said.

There are other biomarkers also being pursued for their same potential to identify patients with a high likelihood to benefit from ASA, which Dr. Chan suggested could help clinicians determine when ASA is appropriate.

In clinical medicine, “we think a lot about biomarkers in respect to predicting who will benefit from cancer therapy, but we have thought less about whether we have the ability to use biomarkers to determine who would potentially be benefiting from a preventive intervention,” Dr. Chan said.

The second identified biomarkers that appear likely to improve the risk-to-benefit ratio from aspirin in cancer prevention. The third cautioned about the potential pitfalls of genetic testing for cancer risk even though the overall effect was to highlight the value of this tool when performed appropriately.

Biomarkers for GI cancer chemoprevention

Citing a long list of studies and trials that have associated aspirin with protection against CRC, including a randomized controlled trial in Lynch syndrome, Dr. Chan characterized the evidence of a chemoprotective effect from ASA against GI cancer as “overwhelming.” However, not all individuals may derive a favorable risk-to-benefit ratio due to the antiplatelet effects of ASA that increase risk of bleeding events in the GI tract and elsewhere.

The best approach to providing a favorable risk-to-benefit ratio may involve identifying biomarkers that predict benefit. The progress in understanding how ASA inhibits pathways of tumor development has provided candidates, according to Dr. Chan, citing a series of studies, including those conducted at his center.

One proof of concept was derived from work in evaluating tumor expression of cyclooxygenase (COX), the enzyme that converts arachidonic acid to prostaglandins. Dr. Chan explained that prostaglandin are linked to many downstream cancer-promoting pathways. In a study that involved molecular analysis on tumor specimens from patients who participated in a cohort study, the presence of the COX-2 isoenzyme was a differentiator.

“When the evaluation was performed according to COX-2 status, we saw about a 30% reduction in risk for COX-2-positive tumors. In contrast, we did not see any appreciable reduction in risk in tumors that were COX-2-negative,” Dr. Chan reported.

Although Dr. Chan acknowledged that about 80% of CRC tumors are COX-2-positive, which may explain why CRC protection from ASA is observed in an unselected population, he reported that this study has supported pursuit of additional biomarkers, particularly those that might predict protection from ASA before or at the very earliest stages of the neoplastic process.

One such candidate is 15-prostaglandin dehydrogenase (15-PGDH) enzyme, which is known to catabolize or breakdown prostaglandin. When 15-PDGH levels were evaluated in normal tissue samples adjacent to CRC tumors, there was about a 50% reduction in risk of CRC in those with high 15-PGDH “but there was actually no reduction in risk among those with low 15-PGDH,” Dr. Chan reported.

Currently, ASA prophylaxis for preventing CRC is recommended by the U.S. Preventive Services Task Force in individuals who also have an increased risk of cardiovascular disease, but there is no accepted formula for weighing CRC risk against risk of bleeding. Biomarkers like 15-PGDH could be instrumental in guiding decisions for gastroenterologists.

“So you can imagine a strategy in which the endoscopist removes the polyp and also takes a biopsy of adjacent normal tissue to determine whether there are sufficient levels of 15-PGDH to potentially predict whether ASA will have a preventive effect,” Dr. Chan said.

There are other biomarkers also being pursued for their same potential to identify patients with a high likelihood to benefit from ASA, which Dr. Chan suggested could help clinicians determine when ASA is appropriate.

In clinical medicine, “we think a lot about biomarkers in respect to predicting who will benefit from cancer therapy, but we have thought less about whether we have the ability to use biomarkers to determine who would potentially be benefiting from a preventive intervention,” Dr. Chan said.
