Covid-19 – Friends, Survival of the Fittest, Focus on Reality and Forget about PC



Replacing the EU Flag with the Chinese Flag in Italy

In times of crisis people often find out who their friends really are.  In Northern Italy teams of doctors and equipment arrived from China, Russia and Cuba.  The citizens of a town in Italy have taken down the blue EU flag and replaced it with a red Chinese one.

Some Americans on social media think it is a "photoshop job".  Where we live Chinese doctors have also arrived, along with donated ventilators and other equipment.  The Chinese flag is fluttering on many video/digital billboards.

We should note that Italy sent aid to China, when Covid-19 first appeared. 
  
In most countries treatment guidelines have been published to determine how to treat patients and how to ration the limited available medical resources.  There is nothing new in rationing medical resources, it happens every day.

In terms of therapy, the note linked to below (in English), is very good.  It includes both chloroquine and hydroxychloroquine, mentioned in my initial post.  Note the dosage is tapered, as I suggested in my post.  In the case of hydroxychloroquine, you only need 12 tablets; so a standard pack can treat 5 adults.  Time for emergency production to start? Or we have to wait for the Chinese to do that for us?




Note that these drugs may have side effects, in particular QT prolongation of your heart beat.  This is a possible side effect of many drugs,  You would not want to combine multiple drugs that prolong QT. The QT interval is measured by ECG.






I am pretty sure I took chloroquine many years ago when travelling in a malaria infected area and never had an ECG.  It is clearly a case of balancing risks.  



Back to triage 

In the Napoleonic wars the French came up with the word triage and by the time of the World War One they had fine-tuned it. Those collecting the injured had to categorize patients into one of three groups:-

·         Those who are likely to live, regardless of what care they receive
·         Those who are unlikely to live, regardless of what care they receive
·         Those for whom immediate care might make a positive difference in outcome

In the current Covid-19 outbreak patients are first split into two groups: -

·        At-risk group, based on age and existing medical conditions 
·        Not in an at-risk group, based on age and existing medical conditions

Severity of the Disease

·        Mild to moderate, the case for most people (no pneumonia or oxygen required)
·        Severe, breathing difficulties requiring oxygen
·        Critical, ARDS (Acute Respiratory Distress Syndrome), Sepsis, Multi organ failure.  The people with critical severity require mechanical ventilation and intensive care

Frailty assessment

The clinical frailty scale (CFS) is used to give a rating from 1 (very fit) to 9 (terminally ill).  Each patient is given a CFS score when it is necessary to ration care.

People with a disability obviously do not want to get a black mark in the frailty assessment.

When overwhelmed with sick people, those working in hospital are not going to be able to devote time to people who are disruptive (aggression, self-injury etc) or those who need a family member at their bedside.

Another issue is where to put disabled people after treatment, so they do not block hospital beds needed for others.  In Italy hotels have been taken over to house people who are still infectious, but not seriously ill.

People who have intellectual disability (ID/MR) are not so easy to house, as this recent article highlights.

Developmentally Disabled New Yorkers Stuck in Hospital After COVID-19 Recovery
According to AABR ( Association for Advancement of Blind and Retarded), a non-profit with a New York State contract to house roughly 200 adults with developmental disabilities, their staff does not have enough necessary masks and gowns to safely retrieve 12 autistic and developmentally disabled residents who are ready for discharge after being treated for coronavirus.

Nine of those patients tested positive and six more hospitalized are awaiting test results. The 12 patients no longer require hospitalization, but are still considered contagious.  

“We have twelve individuals who have been hospitalized who are ready for discharge and isolation at home, but we don’t have a safe plan to bring them home,” said Libby Traynor, executive director of AABR, which used to be known as the Association for Advancement of Blind and Retarded, an 80-year-old organization that runs 22 group homes in the five boroughs.  Residents in six of those group homes have tested positive for COVID-19. 

Because of their intellectual disabilities, many of the AABR clients are unable to speak, let alone comprehend and follow safe social distancing and isolation rules, and the virus appears to be spreading rapidly within their facilities.

"It’s a pretty big ask to ask folks to take care of individuals, and they don’t have the protective equipment that they need,” Traynor said.


Survival of the Fittest

People affected by disabling conditions are worried that they might suffer from the rationing of hospital resources.  In times of crisis political correctness goes out of the window and it is back to survival of the fittest.  Younger healthier people get priority because they have more potential future years ahead of them and they recover faster and make space for the next patient.
  
Complaining that it is not fair is not going to help you.  Assigning ventilators by lottery, as some suggested, is just deluded. Fortunately, rationing life-saving treatment is nothing new and systems are in place to maximize the public good.



He, too, asked the Department of Health and Human Services to take action to stop rationing.
The letter, dated March 18, asked the department to "quickly issue a notice to physicians and hospitals specifying the applicability of non-discrimination requirements" of federal disability civil rights law.
Romano says he got a response from Roger Severino, who heads the HHS Office for Civil Rights and that he's now been talking to officials there about taking action.
"We're working very, very closely and very hard to make sure that we get some form of guidance out to the medical community as soon as possible," Romano says.
It's still unclear. If the federal government will respond. And if so: How forcefully.

If you are at high risk, self-isolate.  It is up to you if you want to self-treat, but it is wise to know what you are doing.



An Arizona man has died and his wife is in critical condition after they ingested chloroquine phosphate - an aquarium cleaning product similar to drugs that have been named by US President Donald Trump as a potential treatment for coronavirus infection.
The couple, in their 60s, experienced immediate distress after swallowing the drug, an additive used at aquariums to clean fish tanks, according to Banner Health Hospital in Phoenix.
Chloroquine phosphate shares the same active ingredient as malaria drugs that Trump has touted as possibly effective against Covid-19, the potentially life-threatening disease caused by the coronavirus.

According to the CDC’s at-risk list, people with Classic/ Kanner’s/ Severe autism are at elevated risk from Covid-19.  I have my doubts that young people in this group are at any elevated risk, if they are in good general heath.  Admitting a child with this level of autism to hospital for several days, alone, might cause problems (for the child and the hospital).


Missed Chemotherapy

Many medical procedures have been cancelled.

People are complaining that the delay disembarking from their cruise ship is affecting their chemotherapy. 

They might want to skip the article below from an oncologist.




In the above article the oncologist is brutally frank about the benefit of chemotherapy in most cases.

In effect, she is saying not to worry if you have to stop your chemotherapy.  The positive results in trials do not reflect the real world, where people have comorbidities etc. She says that “Patients are often astonished to hear that common therapies offer less than 5% benefit. The more lines of chemotherapy, the less the chance of success. Hand in hand with benefit goes harm.”

You do wonder why the bar is set so low for not very effective cancer therapy and yet so high for autism therapy. One pill is supposed to works for hundreds of different autism variants. All avenues are pursued to treat a person with cancer, but no avenues are pursued for someone with autism and intellectual disability. 

The same is actually true with dementia drugs, which are pretty much a placebo for the family members, rather than an effective therapy.


Conclusion

The currently recommended Chinese solution is mass testing to identify all those carrying the virus, most of whom have minor symptoms or no symptoms and then isolate them, so they cannot infect their family members and others.

My solution would be mass treatment of healthy people (no people with abnormal ECGs) with prophylactic doses of Chloroquine, to stop the virus spreading.  The drug is very cheap and it is much easier to make more of this drug than millions of ventilators. Once you take the drug the effect will last for weeks (the half-life is one month), so you could treat whole cities, one by one.  Many old people with arthritis take chloroquine or hydroxychloroquine every day, so I think the QT risk can be managed. 

Chinese doctors found that treating health workers with prophylactic doses of Chloroquine gave them protection from catching the virus from their patients.  15% of those with confirmed Covid-19 in Spain are health workers, so a little advice from China might be in order.   A trial in the UK is planned.

Chloroquine Prevention of Coronavirus Disease (COVID-19) in the Healthcare Setting (COPCOV)

Once hospitals get over-loaded, as they now are in Italy and parts of Spain, there are inevitably people who do not get fully treated.

If you are in the CDC’s at-risk group, it would seem smart to start treatment at home, when the symptoms start, and hopefully avoid the need for triage and “frailty” assessment a few days later.

Anti-viral therapy is most effective when taken early on and in later stages, not surprisingly, has little benefit.

Fish tank cleaner will kill you rather than the virus, but the pharmaceuticals proposed in the medical guidance note from Belgium are saving lives.
