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.

Covid-19 & Digital Health in Italy: “10 Years of Evolution in 10 Days” | WTF Health

By JESSICA DaMASSA, WTF HEALTH

“It’s fair to say that, in Italy, we are doing 10 years of digital health evolution in 10 days.”

Our “man-on-the-street” in Italy (well, man-sheltered-in-place in Italy) Roberto Ascione, CEO of Healthware, reports in on the Covid-19 outbreak and what’s happening with digital health startups, health system partners, and hospitals as Italians continue battling at the forefront of the coronavirus outbreak.

A few weeks ahead of the U.S., there are many things to learn about Covid-19 testing, treatment, outcomes, and timing from the experience in Italy, including some foresight on how pathways for telehealth and digital health continue to evolve as conditions become more serious and the outbreak progresses. (For all you Gretzky fans, this is “skating to where the puck will be” kind of stuff…)

Some navigational guidance on this chat which took place March 26, 2020:

  • Update on Italian Covid-19 outbreak from health industry insider
  • 10:25 minute mark: Digital Health startup case study, Paginemediche, self-triage chatbot data from 70K Italians, data sharing with Italian government & WHO, telehealth model flipping to give overwhelmed physicians opportunity to triage and “invite” patients based on needs
  • 19:10 mark: How to work with Italian digital health startups to advance Covid-19 work

Health in 2 Point 00, Episode 114 | COVID-19 Stimulus Package & Startup Responses

Today on Health in 2 Point 00, we have a viewer question! For our friends who are wondering what will happen to all the IPOs that were supposed to happen this year, I weigh in on how this crisis will impact IPOs and startup funding. On Episode 114, Jess asks me about the stimulus package granting $117 billion to hospitals and for my thoughts on all the startups coming up with ways to address COVID-19. A few startups that come to mind include Conversa with its virtual care conversation, Coronavirus Health Chats, Biofourmis which is looking for ways to track infected people earlier through its AI-powered arm sensor, and Surveyor Health leveraging its data analytics platform as well. For more on this, check out covid19healthtech.com where my colleagues at Catalyst have put together a resource hub for health tech solutions. —Matthew Holt

The New Scarlet Letter

By KIM BELLARD

This piece is part of the series “The Health Data Goldilocks Dilemma: Sharing? Privacy? Both?” which explores whether it’s possible to advance interoperability while maintaining privacy. Check out other pieces in the series here.

If you live in one of the jurisdictions that have imposed stay-at-home requirements, you’re probably making your essential excursions — grocery store, pharmacy, even walks — with a wary eye towards anyone you come across.  Do they have COVID-19?  Have they been in contact with anyone who has?  Are they keeping at least the recommended six feet away from you?  In short, who is putting you at risk?   

Well, of course, this being the 21st century, we’re turning to our smartphones to help us try to answer these questions.  What this may lead to remains to be seen.

We long ago seemed to shrug off the fact that our smartphones and our apps know where we are and where we have been.  No one should be surprised that location is of importance to tracking the spread of COVID-19.  No one should be surprised that it is already being used.  We may end up being surprised at how it will be used.

The THCB Gang Episode 2, (Thursdays at 1pm PT/4 ET)

This episode of “The THCB Gang” is up here as a video (you could also see it live at 1PT/4ET every Thursday) and it’s also preserved as a weekly podcast and available on our Itunes & Spotify channels a day or so later. Each week 4-6 semi-regular guests drawn from THCB authors and other assorted old friends of mine will shoot the shit about health care business, politics, practice, and tech. It should be fun but serious and informative!

This week, joining me was Michael Millenson (@MLMillenson), Grace Cordovano (@GraceCordovano), Vince Kuraitis (@VinceKuraitis), Brian Klepper (@bklepper1) Ian Morrison (@seccurve) & Anish Koka (@anish_koka). A fun and argumentative discussion about where the COVID-19 crisis is right now and what it’s going to mean both now and in the near future — Matthew Holt

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.

Telehealth Startup CEO On How Covid-19 Is Changing Telemedicine Use In Hospitals | WTF Health

By JESSICA DaMASSA, WTF HEALTH

Jamey Edwards, CEO of one of the larger in-hospital B2B telehealth startups in the US, Cloudbreak Health, is already seeing changes in the way hospitals are using his company’s telemedicine services in the wake of COVID-19.

From a noted rise in the rate of infectious disease consults, to “quarantine rooms” where telemedicine equipment is cleverly deployed to practice “clinical distancing” to minimize risk to front-line healthcare workers (and also preserve PPE), Jamey talks about what he’s seeing among hospital clinicians and what they seem to need most right now from telehealth providers amid the COVID-19 outbreak.

With changes to licensing regulations, HIPAA policies, and reimbursement changing the very infrastructure around telehealth, will we finally see virtual care become a true part of the healthcare system at-scale?

“One of the hardest things to do in our healthcare system is match cost to acuity,” says Jamey. “I’m not going to say we’ve overvalued the in-person encounter, but we certainly have been very hesitant to step away from it.”

“The fact of the matter is that that’s a bias. And so it’s up to us to look at these biases and say, ‘Well, no. What is the right way to do this?’”

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.
