Who knows who blows?

Could we greet each other in a way that meant we kept 1.5m apart?

Few of us blame the Government for this virus pandemic but on a dreadful day when Australia has twice as many new cases as China (and a 60th of the population) we have to ponder whether we have done enough. Peter Wener in the Atlantic points to a major issues in the USA such as, “… the decision to test too few people, the delay in expanding testing to labs outside the Centers for Disease Control and Prevention, and problems in the supply chain. These mistakes have left us blind and badly behind the curve, and, for a few crucial weeks, they created a false sense of security. What we now know is that the coronavirus silently spread for several weeks, without us being aware of it and while we were doing nothing to stop it. Containment and mitigation efforts could have significantly slowed its spread at an early, critical point, but we frittered away that opportunity.” It sounds a lot like us. Five hundred people getting together at the moment is NOT safe. It is very hard to get tested, and we are being told it may be more difficult.

We have seen TV presenters, film stars and politicians come down with the virus. These people certainly mix with more people than we do day to day, but there are not many of them. So if we extrapolate back from their numbers and determine the rate of infection we will arrive at figures many orders of magnitude above that being reported. Let’s face it:

It is infectious, it is deadly and we need to stop it.

Economic predictions of impact are unlikely to be accurate and should not be listened to. Minimising the spread of the virus will have the most positive economic impact. Short, sharp, severe. Norman Swan has been getting air time to promote more health of the nation approaches. If we stop the growth, we can reopen schools and kindergartens. We can probably keep schools open now for children of emergency workers, health workers and other services that are understaffed.

Most of all we need to consider testing. At the moment we are testing a lot of worried people and groups of people who are in contact with an infected case. If we take a community view rather than an individual view and extreme social distancing is in place, we can check one member of a potentially infected household with symptoms and declare it positive or negative. That household should then be supported at home. Children are likely to be infected very quickly and have no difficulty. The disruption of treating individuals in this situation is massive and quite likely to lead to asymptomatic people thinking they are clear. Household members over 70 in infected households can be removed if asymptomatic and offered alternative accommodation if they do not have the virus after brief quarantine and testing.

Small towns with limited movement in and out can test the first locals with fever, and no travel or contact, as sentinel cases. If the sentinel febrile person is negative then we can assume safely that other fevers in that community are almost certainly negative for a period – perhaps the next seven days. This will be especially important when we add the usual winter viruses to the mix. Obviously any new arrivals with symptoms must be tested.

Regions, such as Central Australia, Cape York and Northern Western Australia (and many others) lend themselves to a regional community approach with community-based testing. The experts on our nation’s 60,000 year old cultures are at grave risk and require extreme measures of preservation. This requires checking all arrivals into the region (which is often one or two roads and an airport or two) and testing any of these who are symptomatic or develop symptoms over the next 14 days. We can tell them when we check them at the regional boundaries. In two weeks they become part of the “viral control” community. We will need sentinel testing in communities, perhaps one or two tests per week. The extraordinary thing in Central Australia is that this will require less than 100 tests a week. If we can “bank” the saved tests, we will be able to carry out contact tracing in the way Singapore has done.

If we are short of tests, lets think about how to use them effectively. It is time for extreme social distancing. Whatever we are putting in place, we need to know where the virus has spread.

The doctor’s concern is the patient’s fear

How often have you listened to a patient’s story and thought, “OMG! This person has a brain tumour.” After a few more minutes listening (if you are into that sort of thing) your concern might have developed into a mere brain abscess or perhaps a cerebral vascular abnormality. Reacting directly to such gut responses is one reason that doctors now do so many CT Scans of peoples’ brains. I am ashamed to admit that we now cause more brain tumours than we detect. That is clearly not good for our patients and the public purse. In fact, it is a disgrace.

So what should we do with this concern that patients so easily generate in our viscera? We ignore it at our peril for we do not know if it is based on reality, searching google and incorporating the symptoms, a grief reaction to the death of a loved one or even just chance. Whatever turns out to be the case, if the patient was not fearful before telling us their story, they will be after they witness our response. 

What I am saying is – the doctor’s concern and the patient’s fear is the same thing. Singular. One. 

 There is a solution. To respond as a professional rather than as a social being. The neighbour, friend or chat room acquaintance will stay with the patient’s fear – “You need a CT Scan my friend”. As a doctor you can feel and acknowledge the concern, either internally or openly with the patient, and recognising that it is probable that the patient is afraid of whatever you have become concerned about. Now park that concern and go about your professional business.  You can continue gently with the history gathering information that might confirm or refute the possible calamity and examine the person carefully. I cannot stress enough the need to examine people carefully if you are going to refute their fear and explain the symptoms another way. The laying on of hands shows care and attention to detail and justifies our professional opinion.

There is still work to do but investigation is not usually helpful if you do not think it will change the management. Investigation may mean an easy life for you and the patient might attend less in the short term. But the patient has proven that they were right to be afraid and shown that the doctor needed to do a test in order to discover that the feared condition was not present. What is that patient to do when the symptom recurs? How long is a reasonable gap before the test is required again as the doctor is unable to allay the fear without the result? It is a bit like the acceptable period before a widow or widower takes a new partner: there is a wide variety of opinion and a lot of gossip.

 Once in a while, the fear may be so out of touch with reality that it is best to refute this in theory and avoid getting dragged into a clinical black hole. I met a patient who was repeatedly terrified that she had melanoma and would only trust a biopsy result; the doctors were concerned. When I refused to do this on the grounds that she had no added risk and normal skin, she became a very frequent attender for a skin check. It was only when we began to focus on the rest of her life that this fear resolved. 

So use your fear barometer, your concern dial, but be aware who is pushing it.
