“Essential Oncology”: The COVID Challenge

By CHADI NABHAN MD, MBA, FACP

One harsh Chicago winter, I remember calling a patient to cancel his appointment because we had deemed it too risky for patients to come in for routine visits—a major snowstorm made us rethink all non-essential appointments. Mr. Z was scheduled for his 3-month follow-up for an aggressive brain lymphoma that was diagnosed the prior year, during which he endured several rounds of intense chemotherapy. His discontent in hearing that his appointment was canceled was palpable; he confessed that he was very much looking forward to the visit so that he could greet the nurses, front-desk staff, and ask me how I was doing. My carefully crafted script explaining that his visit was “non-essential” and “postponable” fell on deaf ears. I was unprepared to hear Mr. Z question: if this is his care, shouldn’t he be the one to decide what’s essential and what’s not?

This is a question we are all grappling with in the face of the COVID-19 pandemic. The healthcare industry is struggling to decide how to handle patient visits to doctor’s offices, hospitals, and imaging centers, among others. Elective surgeries are being canceled and advocates are arguing that non-essential outpatient and ER visits should be stopped. Ideas are flying left and right on how best to triage patients in need. Everyone has an opinion, including those who ironically consider themselves non-opinionated.

As an oncologist, these various views, sentiments, tweets, and posts give me pause. I understand the rationale to minimize patients’ exposure and thus prevent transmission. However, reconsidering what we should deem “essential” has made me reflect broadly on our method of providing care. Suddenly, physicians are becoming less concerned about (and constrained by) guidelines and requirements. Learning how to practice “essential oncology” may leave lasting changes in our field.

Immediate Changes Needed for Physicians to Stay in Business During the Pandemic

Practices cannot survive the COVID-19 cash flow crisis

By JEFF LIVINGSTON, MD

Will doctors be able to keep their practices open during the worst pandemic in our lifetime? Our country needs every available doctor in the country to fight the challenges of Covid-19. Doctors working in independent practices face an immediate cash flow crisis threatening their ability to continue services.

The CARES Act was signed into law on Friday, March 27, 2020. The law offers much-needed help to the acute needs of hospitals and the medical supply chain. This aid will facilitate the production of critical supplies such as ventilators and PPE. The law failed to consider the needs of the doctors who will run the ventilators and wear the masks.

Cash flow crisis

Private-practice physician groups experienced an unprecedented reduction in in-office visits as they moved to provide a safe and secure environment for patients and staff. In compliance with CDC guidelines, practices suspended preventative care, nonurgent visits, nonemergent surgery, and office procedures.

These necessary practice changes help keep patients safe and slow the spread of Covid-19. The unintended consequence is an unreported and unrecognized cash flow crisis threatening the viability of physician practices.

This Treatment Could Save Your Life – COVID-19 and Convalescent Plasma Therapy

With a doubling time of cases estimated between 3 days within the U.S. and about 6 days globally (at the time of this writing) COVID-19 is demonstrating its terrifying virulence as it spreads across the world.

What’s perhaps equally terrifying, if not more, is the absence of a known cure or treatment plan for COVID-19. While there has been a lot of attention focused on Hydroxychloroquine and Azithromycin, there has been debate on the scientific validity of these treatment options, either as therapy or as prophylaxis. The impact of a solution certainly has far reaching potential, the scope of the challenge is overwhelmingly large. The editor-in-chief of Science recently wrote that the efforts to find a cure are not just ”fixing a plane while it’s flying — it’s fixing a plane that’s flying while its blueprints are still being drawn.”

There is a promising therapy that may help us weather the COVID-19 storm and, perhaps, flatten the curve. It’s based around science that defines immunology and has already been used in many different diseases, going as far back as the 1918 flu pandemic. This potential treatment is convalescent plasma therapy — using antibodies from patients who have recovered from COVID-19 and then transfusing them into patients who are currently mounting an immune response against the rapidly rising viral loads of COVID-19.

False Negative: Testing’s Catch-22

By SAURABH JHA, MD

In a physician WhatsApp group, a doctor posted he had fever of 101° F and muscle ache, gently confessing that it felt like his typical “man flu” which heals with rest and scotch. Nevertheless, he worried that he had coronavirus. When the reverse transcription polymerase chain reaction (RT-PCR) for the virus on his nasal swab came back negative, he jubilantly announced his relief. 

Like Twitter, in WhatsApp emotions quickly outstrip facts. After he received a flurry of cheerful emojis, I ruined the party, advising that despite the negative test he assume he’s infected and quarantine for two weeks, with a bottle of scotch. 

It’s conventional wisdom that the secret sauce to fighting the pandemic is testing for the virus. To gauge the breadth of the response against the pandemic we must know who and how many are infected. The depth of the response will be different if 25% of the population is infected than 1%. Testing is the third way, rejecting the false choice between death and economic depression. Without testing, strategy is faith-based. 

Our reliance on testing has clinical precedence – scarcely any decision in medicine is made without laboratory tests or imaging. Testing is as ingrained in medicine as the GPS is in driving. We use it even when we know our way home. But tests impose a question – what’ll you do differently if the test is negative? 

That depends on the test’s performance and the consequences of being wrong. Though coronavirus damages the lungs with reckless abandon, it’s oddly a shy virus. In many patients, it takes three to four swabs to get a positive RT-PCR. The Chinese ophthalmologist, Li Wenliang, who originally sounded the alarm about coronavirus, had several negative tests. He died from the infection.

Infection Control for COVID-19 Imaging

By STEPHEN BORSTELMANN, MD

Occasionally, you get handed a question you know little about, but it’s clear you need to know more.  Like most of us these days, I was chatting with my colleagues about the novel coronavirus. It goes by several names: SARS-CoV-2, 2019-nCoV or COVID-19 but I’ll just call it COVID.  Declared a pandemic on March 12, 2020 by the World Health Organization (WHO), COVID is diagnosed by laboratory test – PCR.  The early PCR test used in Wuhan was apparently low sensitivity (30-60%), lengthy to run (days), and in short supply.  As CT scanning was relatively available, it became an important diagnostic tool for suspected COVID cases in Wuhan.

The prospect of scanning thousands of contagious patients was daunting, with many radiologists arguing back and forth about its appropriateness.  As the pandemic has evolved, we now have better and faster PCR tests and most radiologists do not believe that CT scanning has a role for diagnosis of COVID, but rather should be reserved for its complications. Part of the reason is the concern of transmission of COVID to other patients or healthcare workers via the radiology department.

But then someone asked: “After you have scanned a patient for COVID, how long will the room be down?” And nobody really could answer – I certainly couldn’t.  A recent white paper put forth by radiology leaders suggested anywhere from 30 minutes to three hours. A general review of infection control information for the radiologist and radiologic technologist can be found in Radiographics.

So, let’s go down the rabbit hole of infection control in the radiology department. While I’m a radiologist, and will speak about radiology-specific concerns, the fundamental rationale behind it is applicable to other ancillary treatment rooms in the hospital or outpatient arena, provided the appropriate specifics about THAT environment is obtained from references held by the CDC.

CT scanning is just awful for diagnosing Covid-19

By LUKE OAKDEN-RAYNER, MBBS

I got asked the other day to comment for Wired on the role of AI in Covid-19 detection, in particular for use with CT scanning. Since I didn’t know exactly what resources they had on the ground in China, I could only make some generic vaguely negative statements. I thought it would be worthwhile to expand on those ideas here, so I am writing two blog posts on the topic, on CT scanning for Covid-19, and on using AI on those CT scans.

As background, the pro-AI argument goes like this:

  1. CT screening detects 97% of Covid-19, viral PCR only detects 70%!
  2. A radiologist takes 5-10 minutes to read a CT chest scan. AI can do it in a second or two.
  3. If you use CT for screening, there will be so many studies that radiologists will be overwhelmed.

In this first post, I will explain why CT, with or without AI, is not worthwhile for Covid-19 screening and diagnosis, and why that 97% sensitivity report is unfounded and unbelievable.

Next post, I will address the use of AI for this task specifically.

American Telemedicine Has Gone Viral

By HANS DUVEFELT, MD

It took a 125 nanometer virus only a few weeks to move American healthcare from the twentieth to the twenty-first century.

This had nothing to do with science or technology and only to a small degree was it due to public interest or demand, which had both been present for decades. It happened this month for one simple reason: Medicare and Medicaid started paying for managing patient care without a face to face encounter.

Surprise! In the regular service industries, businesses either charge for their services or give certain services away for free to build customer loyalty. In healthcare, up until this month, any unreimbursed care or free advice was provided on top of the doctors’ already productivity driven work schedules.

“EVERYTHING WE DO BEFORE A PANDEMIC WILL SEEM ALARMIST. EVERYTHING WE DO AFTER WILL SEEM INADEQUATE”

—Michael Leavitt

Last updated 3/18/2020.

Why are we writing this? 

The COVID-19 pandemic has reached a point where containment is no longer possible. The COVID-19 threat is real, and rapidly getting worse. Many of you are very nervous, some are unsure of the validity of the information you are reading. As physician leaders, we felt it was important to craft a resource you can rely on as being scientifically accurate and one which contains as much actionable information and guidance as possible. 

Accurate, actionable information during an epidemic can save lives. Physicians are on the front line of this epidemic. Not only are we treating the sick, but we are also cringing at the misinformation spread through both traditional broadcast and social media. Evidence matters. Unfortunately, evidence is often slow, methodical, and boring and has a tough time against clicky headlines and exaggeration. We believe that an accurate representation of the current COVID-19 pandemic followed by a set of actionable steps you, your loved ones, politicians and local officials can utilize is of paramount importance and ultimately could save tens of thousands of lives. 

COVID-19 isn’t just the flu? 

COVID-19 has been described by some as “just a cold”, or just like the common flu. COVID-19 is not the common flu. COVID-19 is an order of magnitude worse than the flu. The fatality rate is approximately 10 times worse than the flu.

The flu spreads from September through April in the US, and June through August in the Southern Hemisphere. Yes, it does cause severe illness in many, but it does so over a longer time course. Time is a variable that is working against us during this COVID-19 outbreak. COVID-19 victims will be presenting to a hospital in need of critical care at a rate that is far higher than occurs with the flu.

In addition, these patients will be requiring hospital treatment over the course of a few weeks rather than the 3-4 months of a typical flu season. The healthcare system in the USA is not ready to handle tens of thousands or hundreds of thousands of people over a short time frame. In Italy, the healthcare system buckled under the strain and the healthcare teams are now forced to make horrible life and death decisions.

How Concerned Should Patients Be About An Irregular Heartbeat?

By KOUSIK KRISHNAN, MD

As many industries and individuals are struggling publicly with burnout, a new study from the European Journal of Preventative Cardiology links the “burnout syndrome” with atrial fibrillation (afib). The findings are both interesting and valuable. In general, the public benefits from anything that can raise awareness of heart disease, because early intervention directly impacts improved patient outcomes.

However, headlines that describe afib as a “deadly irregular heartbeat” go too far in the name of public awareness. The truth is, afib is not a sudden killer like a heart attack, cardiac arrest, or stroke. While afib is undeniably serious, it can often be identified in advance and managed with evaluation and treatment. 

Afib is a very common arrhythmia that has numerous risk factors, including hypertension, diabetes, obesity, and sleep apnea, to name just a few. When the heart goes into atrial fibrillation, the upper chambers go into a fast, chaotic and irregular rhythm that often makes the pulse race and feel irregular. Other symptoms can include palpitations, shortness of breath, and dizziness. Some people may not have any symptoms at all. Stroke is the most devastating consequence of atrial fibrillation, but is rarely the first manifestation of the disease.

It is also important to note that afib may not always be present. For this reason, often the arrhythmia is gone by the time someone seeks medical attention, making the arrhythmia harder to diagnose. Fortunately, consumer devices, such as the new Apple Watch, have algorithms to help detect atrial fibrillation. These technologies hold immense promise. They are already helping many people manage their health, and even potentially diagnose some people who never knew they had afib.

Pandemic Fears: What the AIDS Battle Should Teach Us About COVID-19

By ANISH KOKA, MD

As the globe faces a novel, highly transmissible, lethal virus, I am most struck by a medicine cabinet that is embarrassingly empty for doctors in this battle.  This means much of the debate centers on mitigation of spread of the virus.  Tempers flare over discussions on travel bans, social distancing, and self quarantines, yet the inescapable fact remains that the medical community can do little more than support the varying fractions of patients who progress from mild to severe and life threatening disease.  This isn’t meant to minimize the massive efforts brought to bear to keep patients alive by health care workers but those massive efforts to support failing organs in the severely ill are in large part because we lack any effective therapy to combat the virus.  It is akin to taking care of patients with bacterial infections in an era before antibiotics, or HIV/AIDS in an era before anti-retroviral therapy.  

It should be a familiar feeling for at least one of the leading physicians charged with managing the current crisis – Dr. Anthony Fauci.  Dr. Fauci started as an immunologist at the NIH in the 1960s and quickly made breakthroughs in previously fatal diseases marked by an overactive immune response.  Strange reports of a new disease that was sweeping through the gay community in the early 1980’s caused him to shift focus to join the great battle against the AIDS epidemic.
