ED Muskoka Physicians - Living the Dream

travel

Hey gang,

Anyone travel within the last 14 days out of country….the new isolation guidelines that came out today do apply…

give me a call or text if you have and I will walk you through it!

!

conference call

call in number for conference calls – for ED group

always the same 705-704-9984

PIN 0001255

communication

Hi all, good group chat this am. Sorry if you couldn’t make it.

If you have questions please ask one of us that was on the call (Evan, Kelly, Deb, Emma, Adam, Heather, Nelson, Jeff, Mike, Kirsten, Stacey) as we can share group brain with you.

Tuesday – heads up – a patient with COVID intubation sim – Dr Jewell and Dr Smith…!! Great SIM . Thank you both in advance.

Allyson Snelling just resent the simcoe muskoka update and the MAHC community test site info about again this am to the emails she has for all Md’s. If you didn’t; get from her please contact with what email you want on these…then you should get all future updates.

Just spoke to Allyson some are easy fixes and some are not.

MD conference call

COVID CHAT for MAHC ED docs tomorrow at 8:30 am.

call 705-704-9984

pin:0001255

Intention is to discuss our updated local plan, answer questions of each other about the covid 8 update from MAHC and community test sites info just sent out. Most of us are Type A ( hint , hint) and no one has all the answers or do we need to micro manage others but lets brainstorm, feel we are all on the same page, and support each other and our care of our community and our nurses/teams, etc. Max time 30 mins.

Update

So – although I am signed out as director the next 9 days I just cancelled our family trip to the USA. Bummer. I know a couple of you who have done the same.

So many of us will be around when we weren’t gonna be before.

Hard times for us all. But safety is likely in numbers for our groups as some of us may get sick and not be able to work. Hopefully not…but likely. And if we aren’t leaving the country then no automatic quarantine or risk of being caught in another country.

Please is you feel sick consider calling me ( or the acting director) to plan what to do with some support. Please be ready as the back up doctor . Also if we are dropping like flies I will be reaching out to community MD’s to back up us and the hospital.

We need to be healthy as a team and help each other ( insert group hug here with a one meter distance between each of us for social isolation)!

I propose we start having “opt in” conference calls as a way to ask questions of each other as MD’s and see what is happening on the front line ( practical stuff ). More info to come.

Hep A

Final update on Hep A issue in Muskoka as public health information I circulated and Liz sent out to all Muskoka Md’s…

If you have questions about a patient in front of you around this issue and need help Angela Hollingshead is happy o help. She has had lots of discussions with public health around this…

ED MAHC COVID 19

Just thought I would send out a couple practical things…

  1. keep reading updates from MAHC , OMA, latest in NEJM, etc as you feel you can to keep up to date with COVID 19 – the media is over the top in lots of ways so just be careful your sources. Some restrictions of public events may be driven by political or “non – science” reasons.
  2. MAHC is gonna try and focus future communications on operational/MAHC and community based efforts as I have asked for more practical frontline guidelines and aid as this is what we need.
  3. limit visitors in ER – this should be enforced at all times
  4. hospital entry screening – starting – as in communication today
  5. If patient being sent to the ER for swab by public health this doesn’t mean they need to be seen by a doctor. If nursing worried about patient then we should see them. I also suggest we offer to see the patient and nursing ask the patient that and chart it…. So far my N of 5 have all declined.
  6. community test sites on the horizon – I’m told – they are awaiting “approval my public health” and then this will be communicated out.
  7. testing at MD discretion …hard to know who to test – travel history and illness is recommended but if was at a conference? or an NBA game this week? Just keep in mind we have limited tests in Ontario and we are still waiting pandemic planning guidance…hopefully this is coming soon.
  8. Donning and doffing update /refresher by Angela Hollingshead (occupational health) at anytime…just give her a call. You could even mock up an intubation scenario with RT/Angela and others if you want to do! If you want me to organize let me know.

COVID 19

I thought this might be a good time to review COVID 19 and coronaviruses.

Intro:

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV)A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.  

Coronaviruses are zoonotic, meaning they are transmitted between animals and people.   SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans. 

Best preventative strategies are: WASH YOUR HANDS; stay 1-3m away from people in social situations; cover your mouth with your elbow if you cough or sneeze; avoid touching your face,nose or eyes. Avoid close contact with people who are sick; stay home when you are sick; and clean and disinfect frequently touched objects and surfaces. Coronavirus is spread by DROPLET transmission and these steps above minimize exposure to droplets.

What about masks?

  • If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV infection.
  • Wear a mask if you are coughing or sneezing.
  • Masks are effective only when used in combination with frequent hand-cleaning with alcohol-based hand rub or soap and water.

What about Canada? To date there are 77 confirmed cases in Canada, 34 in Ontario. That number will go up.

How infectious is COVID 19?

It looks like it is more infectious that influenza. The R0 is a measure of how readily a virus is transmitted. The R0 for influenza ia 1-2-1.4 and the estimates for COVID 19 are around 3. This means for every one person infected they will pass it along to three other people.

What is the case fatality rate of COVID 19?

This is a moving target. Early in the outbreak when only the sickest patients were being identified, the case fatality rate (CFR) was over 10%. That number is steadily decreasing as more cases are being diagnosed and more testing is being done. The denominator now will include the MANY people who have mild symptoms. Still, the most current estimates have the CFR at 2-3%. A study in the NEJM had the mortality rate estimated at 1.4%. Some areas are reporting mortality rates of less than 1%. We won’t know for a while longer the best estimate for mortality rate but for now it looks to be more serious than seasonal influenza. On average seasonal influenza has a mortality rate of about 0.1%.

Your age matters when estimating mortality rate!

Under the age of 40, the death rate so far is only 0.2%; 0.4% for ages 40-49; 1.3% for 50-59, 3.6% for 60-69; 8% for 70-79 and 15% for 80-89.

Comorbidities Matter:

Death rate higher if you have cardiovascular disease (10.5%), respiratory disease (6.3%) , diabetes (7.3%), hypertension (6%) or cancer (5.6%). The death rate fwith no known conditions is aorund 0.9% currently.

What is the clinical spectrum of the disease?

So far, it seems that fever, dry cough and dyspnea are the commonest symptoms. However, influenza-type symptoms including sore throat, headache and myalgia have also been described in some). So far, about 80% of cases have been classified as mild, 14% severe (dyspnea, pneumonia) and 5% critical (respiratory failure, septic shock, and/or multiple organ dysfunction/failure). Sympotms can atake up to 14 days after exposure to develop.

What should you do if you see a patient with severe acute respiratory illness (SARI) and possible exposure to COVID 19?

Take precautions mentioned previously. Mask on patient. Mask on providers. Gown and eye protection on provider.

Early supportive therapy and monitoring. Give supplemental oxygen therapy immediately to patients with SARI and respiratory distress, hypoxia, or shock.

Use contact precautions when handling contaminated oxygen interfaces of patients with nCoV infection.

Use conservative fluid management in patients with SARI when there is no evidence of shock. Remarks: Patients with SARI should be treated cautiously with intravenous fluids, because aggressive fluid resuscitation may worsen oxygenation, especially in settings where there is limited availability of mechanical ventilation.

Give empiric antimicrobials to treat all likely pathogens causing SARI. Give antimicrobials within one hour of initial patient assessment for patients with sepsis. Although the patient may be suspected to have nCoV, administer appropriate empiric antimicrobials within ONE hour of identification of sepsis. Empiric antibiotic treatment should be based on the clinical diagnosis (community-acquired pneumonia, health care-associated pneumonia [if infection was acquired in healthcare setting], or sepsis), local epidemiology and susceptibility data, and treatment guidelines. Empiric therapy should be de-escalated on the basis of microbiology results and clinical judgment.

Do not routinely give systemic corticosteroids for treatment of viral pneumonia or ARDS outside of clinical trials unless they are indicated for another reason. A systematic review of observational studies of corticosteroids administered to patients with SARS reported no survival benefit and possible harms (avascular necrosis, psychosis, diabetes, and delayed viral clearance). A systematic review of observational studies in influenza found a higher risk of mortality and secondary infections with corticosteroids; the evidence was judged as very low to low quality due to confounding by indication. A subsequent study that addressed this limitation by adjusting for time-varying confounders found no effect on mortality. Finally, a recent study of patients receiving corticosteroids for MERS used a similar statistical approach and found no effect of corticosteroids on mortality but delayed lower respiratory Clinical management of severe acute respiratory infection when Novel coronavirus (2019-nCoV) infection is suspected:

Application of timely, effective, and safe supportive therapies is the cornerstone of therapy for patients that develop severe manifestations of 2019-nCoV. Understand the patient’s co-morbid condition(s) to tailor the management of critical illness and appreciate the prognosis. Communicate early with patient and family.

suture/instruments

Hi all,

Friendly reminder… don’t throw out equipment that can be cleaned !! ( reusable suture kits, fine instrument trays, etc)

We are loosing instruments left, right and centre!!! Some for sure to the garbage!!

Also – based on the plastics session yesterday – I have asked for 3, 4,5 vicryl rapide in both sites all the time and more derma bond if you plan to use as a dressing!!

I will put my plastics protocol book in SMMH ER tonight as a reference book for anyone to use! Perhaps one of the other docs want to put theirs in HDMH ER?
