A.   Introduction

 

Welcome to the Internal Medicine COVID-19 Team. First, we want to thank you for your service in caring for these sick patients during these unprecedented and uncertain times. Additionally, we want to thank you for the sacrifice you made by being on the front lines during this pandemic. Although, we hope the public health initiatives will curtail the spread of this disease to avoid overwhelming levels, we understand the paramount importance of preparation for mass casualty and disaster events. In this light, we have provided a survival guide with important information on COVID-19 as well as the evaluation, admission, management, and discharge of COVID-19 patients as it pertains to Naval Medical Center Portsmouth. Again, thank you for continuing to make Naval Medical Center Portsmouth the “First and Finest”.

Disclaimer: Please note that information regarding the appropriate diagnosis, management, and disposition of COVID-19 Persons Under Investigation (PUI) or positive patients is changing rapidly. This document is meant to serve as a guideline but may inevitably change as new research or command decisions come to light.  Lastly, this guide was designed to be an adjunct to assist with patient management but is in no way a substitute for individual clinical judgment and medical decision making.

B.   Basic Science/Epidemiology

1.      Biology

Novel coronavirus, or SARS-CoV-2, is a non-segmented, positive sense RNA virus that belongs to the larger coronavirus family, of which there are now seven known members. Four of these viruses are responsible for mild respiratory illness including the common cold [229E, NL63, OC43, HKU1] while MERS-CoV and SARS-CoV-1 cause MERS and SARS respectively.

SARS-CoV-2, which causes novel coronavirus 2019 or COVID-19, is most closely associated with SARS-CoV-1, the virus responsible for the SARS epidemic in 2003. A significant relation between the two viruses is the mechanism by which they enter host cells: the ACE2 receptor, a receptor that has been shown to be present on type II pneumocytes, intestinal epithelia, and nasal mucosa in addition to many other locations.

2.      Pathophysiology

1.       Hypoxemic respiratory failure

a.       Pneumocytes have been shown undergo cytopathic effect, indicating direct viral damage rather than damage secondary to inflammation.

b.      COVID-19 has also been shown to reduce surfactant levels, leading to alveolar collapse, atelectasis, and de-recruitment.

c.       Likely mechanism of lung injury is “diffuse alveolar damage” or Acute Respiratory Distress Syndrome (ARDS), which has led to the adoption of many principles of ARDS management for COVID-19 patients.

2.       Cytokine Storm

a.       Around day 7-10 of illness patients can acutely worsen which can manifest as recalcitrant fever, cytopenias, elevated liver associated enzymes, multi-organ system failure, elevated ferritin levels, and disseminated intravascular coagulation.

b.      This has been shown to likely be related to immunological hyperactivation triggered by the virus or its associated immune response, similar to hemophagocytic lymphohistiocytosis (HLH) or CAR-T cell cytokine release syndrome but appears to be distinct from these conditions.

 

3.       Disseminated Intravascular Coagulation

a.       Later in the disease course, patients can present with signs of disseminated intravascular coagulation (DIC) with rising d-dimer correlated to poorer prognosis.

b.      Etiology could be secondary to HLH-like immunologic activation and associated up-regulation of fibrinogen versus direct binding of the virus to ACE2 receptors on endothelial cells.

4.       Pro-thrombotic and inflammatory pathophysiology and consequences

a.      Venous thromboembolism (VTE), including extensive deep vein thrombosis (DVT) and pulmonary embolism (PE), is very common in acutely ill patients with COVID-19, seen in up to one-third of patients in the intensive care unit (ICU), even when prophylactic anticoagulation is used.

b.      This state has been termed thromboinflammation or COVID-19-associated coagulopathy (CAC) by some experts. It appears to be distinct from disseminated intravascular coagulation (DIC), though DIC has been reported in severely affected patients (as discussed above).

c.       There are also reports of arterial thrombosis, including in the central nervous system (CNS). The largest study, which included 3334 individuals (829 ICU and 2505 non-ICU) reported stroke in 1.6 percent and myocardial infarction in 8.9 percent.

3.      Transmission

COVID-19 has been shown to have various modes of transmission that impact how we appropriately care for these patients as well as the healthcare staff to ensure safety and limit spread of infection.

1.       Large Droplet Transmission

a.       A primary mode of transmission was found in large droplet transmission, which is typical for respiratory viruses such as influenza. Most societies recommend that risk is greatest within 6 feet of an actively infected patient.

b.      Risk is mitigated to an acceptable degree by the patient and provider wearing a standard surgical mask.

2.       Airborne Transmission

a.       There is increasing evidence that COVID-19 can also be transmitted via an airborne route, thus implying the need for a provider to wear a fitted N95 mask.

b.      There have been recent studies to suggest that COVID-19 can persist in aerosols for hours.

c.       Most transmission is still believed to occur by droplet rather than aerosol transmission, though certain medical procedures may increase the risk of aerosolization.

d.      Negative pressure isolation is ideal; however, availability and initial risk assessment will determine which patients are placed in isolation

3.       Contact Transmission

a.       COVID-19 has been shown to persist on certain fomites for up to 4 days, lending to a possible risk for inoculation through direct contact.

b.      When a patient coughs, droplets deposit on fomites creating a thin film.  A second, uninfected person can come in contact with the fomite, touch mucosal membranes and become inoculated.

c.       This can be mitigated with regular deep cleaning of rooms during turnover, thorough and frequent hand washing, and avoidance of facial touching.

The Basic Reproduction Number, Rø, is an epidemiologic term that can be thought of as the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection.  If Rø is < 1, the disease will eventually burn out. If Rø is > 1, the disease will increasingly infect hosts in an exponential fashion. Current Rø estimates for COVID-19 are approximately 2.5-2.9.

Importantly, Rø is a reflection of transmissibility, contact between susceptible and infected individuals (human behavior), and duration of infectiousness.  Public health measures such as physical distancing and closing public businesses have had significant impact on the effective reproduction number over time, Rt or Re. Additionally, there is recent evidence to suggest that R may vary between different individuals depending on things like their contact rate with others and viral load. An asymptomatic patient with a high-viral load, or high contact rate, may infect many more people (super-spreader) than a similar patient with lower viral load or contact rate.

C.   Personal Protective Equipment

Protecting yourself, as a healthcare worker (HCW), before entering the room of a patient suspected of having COVID-19 with the proper equipment is paramount to limiting the spread of infection to yourself and other coworkers. This could have significant consequences regarding staff shortages for our hospital as well as putting the community at risk. Even more important is learning the correct protocol for donning and doffing this equipment.

Important for preventing transmission of SARS-CoV-2 in the healthcare settings is having at least two layers of protection for all contacts (non-COVID-19 patient to HCW, HCW to HCW, etc.).  One layer is your own mask.  The second can be a mask on the patient or eye protection on you (or both).

This video from the DoD CPG Guideline reviews procedures:

1.       Donning

a.       The correct order for donning personal protective equipment (PPE) prior to entering the room of a patient suspected of having COVID-19 is GOWN, MASK, GOGGLES/FACE SHIELD, THEN GLOVES.

2.       Doffing

a.       Doffing PPE is often considered the more challenging step as well as the most important to ensure mitigation of potential spread.

b.      Prior to beginning the doffing process, first apply hand sanitizer from inside the room to your gloves.

c.       Carefully remove gown by pulling the chest area forward, ensuring to keep the gown forward and have the waste bin open.

d.      Carefully roll the gown inside out over the gloves while simultaneous removing the gloves.

e.       Discard bundle of rolled gown and gloves into waste bin.

f.        Clean your hands with soap and water and re-don gloves.  Carefully remove your eyewear touching only the rear-most part of the ear pieces and wipe them down thoroughly with approved sanitizer wipes .

g.       Only once a-f is complete, can you leave the room into the ante room.

h.      Once in the ante room, follow standard procedure for washing hands

i.         While leaning over the waste bin the ante room, carefully remove the straps from the N95 mask and let the mask fall into the waste bin.

j.         NOTE: If conserving goggles and/or N95 mask please follow ward instructions for proper conservation.

D.  Clinical Features at Presentation

The clinical illness script for COVID-19 is constantly changing as more cases are discovered. However, many patients present with lower respiratory symptoms such as cough or dyspnea, fever, upper respiratory symptoms, and/or gastrointestinal symptoms.  Incubation period is a median of 4 days with a range of 14 days. Common presenting symptoms (with percent displaying this symptom at presentation include:

1.       Fever

a.       Data has shown that fever is present in about 50% of patients at the time of hospital admission, signifying that absence of fever does not exclude COVID-19.

2.       Gastrointestinal Symptoms

a.       10% of patients may present with nausea or diarrhea which precede the onset of respiratory symptoms.

3.       “Silent hypoxemia”

a.       There is a subset of patients that present with nonspecific symptoms and are found to be hypoxemic without dyspnea.

4.       Taste/Smell: About 25% of patients will have disturbance in taste or smell.

E.   Additional Resources

Additional resources for more detail (and that are updated routinely) include:

1.       The Internet Book of Critical Care (IBCC): A continuously peer reviewed and updated summary of the literature is available from the IBCC at: https://emcrit.org/ibcc/covid19/

 

2.       DoD Clinical Practice Guideline (CPG):  The DoD has a published practice guideline for COVID-19 available in the same drive as this document. 

3.       American College of Physicians Course on COVID-19: The ACP (internal medicine professional society) has a more in-depth course on COVID that is also updated regularly that walks through the basics of coronaviruses up through current treatments and approaches to COVID-19 and provides a large assortment of resources for further information.

B.   Laboratory Evaluation

 

1.      Basic Laboratory Evaluation

 

Initial testing should include labs that will either 1. aid in risk stratification or 2. add prognostic information. The following are important laboratory tests that add may add to the above information:

 

1.       Complete blood count

a.       WBC counts are typically normal, although lymphopenia commonly is present in COVID-19 patients.  Lymphopenia on admission has been associated with later need for ICU level care and with mortality (ALC of 800 cells/µL and 1100 cells/µL have both been used as cutoffs in analyses)

b.      Elevated Neutrophil to Lymphocyte ratios (NLR) has also been identified as a risk factor for poor outcomes (≥9) .

c.       Lower platelet counts (<100) are associated with poorer prognosis.

2.       Coagulation studies

a.       Laboratory values consistent with DIC can be seen and elevated prothrombin time is associated with poor outcome.

b.      D-dimer > 1.00 is an indicator for poor prognosis but not necessarily indicative of active clotting in these patients, though pulmonary thromboembolism is a common complication.

3.       Inflammatory markers

a.       COVID-19 increases C-reactive protein, which can be marker of disease severity as well as prognosis. 

4.       Procalcitonin

a.       Markedly elevated procalcitonin may suggest bacterial superinfection and have some negative predictive value in COVID-19.

b.      In those that have known COVID-19, elevated procalcitonin may have negative prognostic value. 

5.       Respiratory Viral Panel

a.       NOTE: A positive RVP for a different respiratory pathogen does not rule out COVID-19. Co-infection has been documented in approximately 5% of patients

 

Our department has collaborated on an Internal Medicine COVID-19 Order Set that can be found in Essentris. The following labs are included in the Order Set and should be ordered if not ordered AND collected in the Emergency Department:

 

            Recommended Per DoD CPG:

 

                        Daily

1.       Complete blood count with differential

2.       Comprehensive metabolic panel

3.       C-Reactive Protein

4.       D-Dimer

a.       Note: This is NOT necessarily out of suspicion for PE, this is linked to prognosis and a positive d-dimer does NOT obligate you to get a CTA of the chest but may influence decisions regarding degree of anticoagulation

 

On admission, repeat every 2-3 days if abnormal or clinical deterioration

1.       PT/PTT, Ferritin

2.       Lactate dehydrogenase

3.       SARS-CoV-2 RT PCR Testing (repeat based on admission algorithm above)

4.       EKG

 

If Clinically Indicated

1.       Blood cultures (if starting antibiotics for bacterial infection)

2.       Procalcitonin

3.       Troponin (if suspecting ACS)

4.       BNP (if suspecting heart failure)

5.       Viral serologies for elevated LFTs (HBV sAb/cAb/sAg, HCV Ab, HIV q/2 Ab/Ag)

6.       Urinalysis and spot urine protein:creatinine (For acute kidney injury i.e. serum creatinine >0.3 above baseline)

 

Bear in mind, just because the Emergency Department ordered the test does not mean it was collected and sent to the lab.  You should verify specimens have been drawn and received by the lab.

 

2.      COVID-19 RT-PCR (How to Order COVID-19 swab test)

 

The following is the process for ordering nasopharyngeal swab for RT-PCR COVID-19 to be sent to National Infectious Disease Diagnostic Lab (NIDDL), which has a 1-3 day turnaround, or NMCP Lab test, which uses one of our biofire machines and takes approximately 45 minutes to run but may be delayed if the machines are already in use as they can only run one test at a time.   Labcorp has greatest capacity for tests, but turnaround time varies.  In general admitted patients should get rapid in house test with biofire and outpatients should get NIDDL, unless high risk conditions warrant biofire testing.

 

1.       Go into CHCS order section and find your patient

2.       New -> Lab -> COVID -> COVID-19 (NIDDL) or “Rapid” (In House test)

3.       For NIDDL only, select 5. NASOPHARYNGEAL SWAB (For in-house just answer the questions that will pop up)

4.       For in-house/rapid select diagnosis if admitting for potential SARS-CoV-2 infection

5.        

 

 

6.       Quit back out and print the order to your local printer (“slave” will print to your computer’s default printer)

7.       Exit back to the main CHCS menu

8.       Type ^MRG

9.       Type a space and hit enter to select the same patient you just ordered the swab on

10.   Select file > Print

 

 

 

 

 

 

 

11.   ENSURE BOTH PRINTOUTS WITH YOU AND TRANSPORT TO THE LAB WITH THESE FORMS IN THE BAG WITH THE MINI-REGISTRATION FACING OUT.

 

NOTE: Nasopharyngeal swabs should only be performed by personnel trained to appropriately swab patients. If you are unsure about whether or not you’ve been trained, you should not be doing swabs.

 

C.   Imaging Evaluation

 

Typical imaging findings include bilateral patchy ground glass opacities, which are concentrated in the periphery and basal segments. Findings that suggest an alternative diagnosis include pleural effusions, masses, cavitation, or lymphadenopathy.

 

The radiology department at NMCP risk stratifies cases features on Chest CT scans in patients with potential COVID-19 on a scale of “confidence.” At NMCP, patients with high and intermediate confidence features are determined “radiologically positive” and treated as such, even if initial PCR testing is negative.   The algorithm they use for this is available in the same folder as this guide.

1.      


Example of a CT consistent with “high to intermediate confidence” for COVID-19.

D.  Nasopharyngeal Swab Procedure

 

An adequate specimen retrieved via a nasopharyngeal swab is paramount to successful risk stratification, diagnosis, and management of patients with suspected COVID-19. There is a high likelihood for false negative swabs if not performed correctly, which not only could result in morbidity and a delay in appropriate care for the patient but poses a public health and infection control risk.

 

DO NOT DO THIS UNLESS YOU HAVE COMPLETED THE COMMAND TRAINING.  You may think you know how but time and time again people who have been very confident have been found out to not know what they’re doing leading to false negatives and patient harm.  If you are unsure if you’ve completed the training, then you haven’t.  This section is a reminder for those who have completed the training, not an alternative to completing the command training.

 

1.      Specimen Handling

 

A. Preparation

1. Prepare appropriate tubes/containers, labels, plastic specimen transport bags, a clean Chux (do not use one already in the room) and 2 clean emesis basins. Label one basin “Clean” and the second basin “Dirty”.

2. Place all items in the “dirty” emesis basin.  This will be used to transport these items into the patient room and this basin will remain in the room after specimen collection.

3. Disinfect hands and don personal protective equipment (PPE), putting on a second pair of clean gloves.

 

B. Procedure

1. Place a Chux Pad in the “clean” emesis basin and leave in the Anteroom. Bring “dirty” emesis basin containing supplies and unused specimen transport bags into the patient’s room, do not place on patient bed.

2. Follow standard procedures for patient identification and specimen collection.

3. Place specimen containers/tubes in the dirty basin in the patient room.

4. Label all specimens at patient bedside.

5. Remove 1st pair of gloves and discard.

6. With clean gloves, place labeled specimens into the unused specimen transport bag and seal the bag.

7. Wipe outside of bag with hospital-approved disinfectant wipes.  At this time, the bag is considered “clean”

8. Place “clean” bagged specimens in the “clean” emesis basin (previously placed next to the door in the Anteroom).

9. Bagged specimens should be hand-delivered directly to the lab. Staff should use a one hand gloving technique, by donning gloves on one hand to carry specimen and keeping the other hand clean (to open doors or operate elevators). Remove gloves after drop-off and perform hand hygiene after removal of gloves. Please refer to the COVID-19 Laboratory SOP on the COVID-19 SharePoint Site.”

 

 

 

 

2.      Specimen Collection

 

1.       Stand to one side of the patient with their head in the neutral position facing forward, NOT in a sniffing position

2.       Be aware that the patient may sneeze or cough, stay out of the line of fire!

3.       Insert swab into nasal cavity parallel and along the nasal floor LOW AND SLOW

4.       The nasopharynx is about 9-10cm from the naris opening, this 2/3 of your 15cm swab

5.       At the nasopharynx you will feel some increased resistance.  STOP HERE.  If you feel like you are hitting a “wall,” DON’T PUSH THROUGH IT

6.       Position Twirl in place gently for 3-5 seconds

7.       Slowly withdraw the swab with a rotating motion

8.       Repeat with the other naris

9.       Place the swab into the transfer medium/vial and remove from the room according to the applicable SOP (such as the one above)

 

 

A.   Admissions

 

1.      Severity Assessment

The current disease severity assessment published by the NIH and DoD is as follows:

 

Asymptomatic or Pre-symptomatic Infection: Individuals who test positive for SARS-CoV-2 but have no symptoms

 

Mild Illness: Individuals who have any of various signs and symptoms (e.g., fever, cough, sore throat, malaise, headache, muscle pain) without shortness of breath, dyspnea, or abnormal imaging

 

Moderate Illness: Individuals who have evidence of lower respiratory disease by clinical assessment or imaging and a saturation of oxygen (SaO2) >93% on room air at sea level.

 

Severe Illness: Individuals who have respiratory frequency >30 breaths per minute, SaO2 ≤93% on room air at sea level, ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) <300, or lung infiltrates >50%.

 

Critical Illness: Individuals who have respiratory failure, septic shock, and/or multiple organ dysfunction.

 

Other currently identified risk factors for poor outcomes include:

1.       The laboratory assessments as in the previous section

2.       Demographics

a.       Age > 55

b.      History of pulmonary disease

c.       History of cardiac disease including hypertension

d.      History of chronic kidney disease

e.       Immunosuppression

f.        Obesity

3.       Vital signs

a.       Respiratory rate >24

b.      Heart rate > 125

c.       >2 liter oxygen requirement to keep SpO2 >90%

 

 

2.      Patient Placement

Patient placement will guidelines will be fluid as patient volume changes but in general, risk of intubation should be the guiding metric when deciding if an ICU/CTU consult is indicated.  Communicate early and often with ICU staff and nursing staff to determine appropriate placement based on patient condition and resource availability.

 

3.      Admission Order Set Checklist

 

Our NMCP COVID-19 Working Group has devised a COVID-19 Standard Order Set that can be used for all COVID-19 admissions. The following should be checked on every suspected COVID-19 admission before arriving to the floor.

 

 

Admission Orders

      Team assignment (COVID Team 1, COVID Team 2, Ward Team 1, Ward Team 2, etc.).  The patient will not populate on the rounding list without this order.

      Provider contact information (in admission orders and on discharge tracking screen)

      Code status order

      COVID risk stratification order (note “confirmed” if positive by PCR or CT)

Activity

      Restricted to room for everyone

      Order for negative pressure room if required. Not every patient requires negative pressure and we don’t have bed space to accommodate everyone in negative pressure.

Labs

      COVID admission labs as above in “workup”

      Repeat labs as warranted for other conditions (THERE IS NO SUCH THING AS ROUTINE LABS WITH THESE PATIENTS.  Each lab should be to answer a specific question that could change management and will require staff exposure to collect)

Diet

Ensure is ordered with an isolation tray (completely disposable)

Medications

      Home medications as indicated

      Insulin as indicated

      Community acquired pneumonia treatment if indicated

      Investigational Drug or other therapy

      DVT prophylaxis ordered if not contraindicated

Treatments

      Oxygen orders with goal 92-96%

      Orders to alert provider for increasing O2 requirements which may be heralding a need for high flow oxygen, non invasive ventilation or intubation

      Telemetry orders (order “no telemetry” if it is not desired)

      Order for telemedicine monitor to be appropriately aligned and activated at all times

      Awake proning per protocol (see appendix B)

      Exercise per protocol

Vital signs orders

Select frequency keeping in mind limiting staff exposure as much as is safe for the patient

 

 

4.      Adaptive COVID-19 Treatment Trial 3 (ACTT3)

 

ACTT 2 is currently closed.  ACTT3 is pending. See Appendix B for the ACTT-3 information when it becomes available.

 

5.      Remdesivir

 

The antiviral Remdesivir has been approved by the FDA (in large part due to ACTT-1) for patients age 12 or older, weighing at least 40kg, and requiring hospitalization for COVID-19.  The IDSA recommends this only for those with oxygen saturation <95% on room air.  The medication is contraindicated in patients with known hypersensitivity to any ingredient in remdesivir.  It must be discontinued for ALT > 10x the upper limit of normal, ALT elevation accompanied by signs of liver inflammation, or for eGFR <30ml/min.

 

 

The recommended adult dosing for non-mechanically-ventilated patients is: 200mg IV x1 on day one followed by 100mg IV daily on days four through five.  If the patient does not have clinical improvement the daily dose can be extended for up to 5 more days for a total of 10 days.

 

This medication is discontinued when the patient is well enough to be discharged.

 

Monitoring includes daily

·         Hepatic panel

·         BMP (for eGFR)

·         Prothrombin time

 

6.      Dexamethasone

Like remdesivir, dexamethasone (6mg PO daily for 10 days) can be considered in patients with SpO2 ≤ 94% on room air.  The order is also present in the COVID-19 Standard Admission order set.  Benefit was seen for patients with symptoms > 7 days and was most pronounced for those requiring mechanical ventilation.  This medication is discontinued when the patient is well enough to be discharged.

 

7.      Anticoagulation

 

COVID-19 is known to elicit a pro-thrombotic state in patients, leading to venous increased risk of thromboembolism even on prophylactic dosing of anticoagulation. This seems to be due to a combination of increased levels of clotting factors, acquisition of antiphospholipid antibodies, decreased endogenous anticoagulant proteins and excessive platelet and neutrophil activation with viral mediated endothelial inflammation. AT MINIMUM, DVT prophylaxis is of paramount importance, and patients may even need higher doses than typical prophylaxis as heparin resistance has been seen in some patient with the disease.

 

In summary, please ensure that chemical DVT prophylaxis is on all suspected COVID-19 patients and can be adjusted as necessary by the primary team. Consideration should be given to increasing anticoagulation dose if deemed appropriate. Additionally, there should be a high index of suspicion for venous/arterial thromboembolism in patients presenting with acute worsening of hypoxia or symptoms consistent peripheral emboli.  The below are the current guidelines for anticoagulation published in JAMA in November, 2020:

 

A.   Rounding

 

1.      Daily Rounding Routine

 

Typically, the rounding schedule is determined by the attending running the COVID-19 Team. Based on that schedule, you should consider the following daily events to be documented and checked prior to rounds:

 

 

  1. 24 Hour events
  2. Talk to the patient via phone or VTC (physical exam is NOT required unless to address a specific question)
  3. Review vitals with attention to O2 requirements and fever (as well as antipyretic use)
  4. Review labs

a.       Replete potassium to level of 4 as indicated

SERUM K+ (mmol/L)

K+ REPLETION (mEq)

3.3-3.5

40 IV or PO

3.0-3.2

50 IV and/or PO

2.6-2.9

60 IV and/or PO

<2.6

80 IV and/or PO

      It is best to give mag first if possible

      Separate doses of >40mEq PO by 4 hours, for very low can give both IV and PO simultaneously.  K-Dur is delayed release.

      Peripheral infusion rate is limited to 10mEq/hr; 20mEq/hr by central line

      If creatinine > 2 reduce the above recommendations by 20mEq

b.      Replete magnesium to a level of 2 as indicated

 

SERUM Mg++ (mg/dL)

Mg++ REPLETION

1.6-1.9

1gm IV x1 or 400mg PO q8h x3

1.4-1.5

2gm IV

0.8-1.4

2-4gm IV, check K+

<0.8

4-6gm IV, check K+

      The slower the infusion, the less gets eliminated in the urine. 

      Recommend 1gm/hour if asymptomatic

      Consider reducing dose by 50% if renal dysfunction

 

  1. Review imaging if not already done

 

 

2.      Rounding List

 

The COVID-19 Working Group ™ has created a Rounding List similar to rounding list used by traditional inpatient medicine teams. It is located by accessing the inpatient medicine rounding list and selecting your COVID team number. Please see the Supplementary Appendix if you are unable to locate these lists or have difficulty with acquiring them.

 

3.      Daily COVID-19 Rounding Checklist

 

In the event that the patient load becomes significant for each COVID-19 Internal Medicine Team, our group wanted to provide an efficient, memorable method for rounding that ensures that key decision points, disposition criteria, and other important factors of care are not overlooked. The following mnemonic will also be printed on placards to be passed out to rounding teams:

 

COF AND SPIT

 

COVID status: (Confirmed, Under Investigation, Ruled out), symptom day #

Oxygen requirement: How much. When it was last required?

Fever: Time of last fever, antipyretic use.

 

Antibiotics: Agents used, day __ of __ (if applicable)

Novel Medications

      Agent day __ of __ (if applicable)

De-escalation

      Current vital signs frequency. Can it be reduced?

      Current lab orders. Can they be discontinued or frequency reduced?

      Current telemetry orders. Can it be discontinued?

 

Status: Code status

Prophylaxis: Are they on chemical DVT prophylaxis? If not, why not?

Indication for admission: What is keeping them from de-escalating level of care or going home?

Transition: What barriers to safe discharge exist? (e.g. is there a good plan for where they will go after the hospital)

 

4.      Telemedicine

 

In an effort to reduce unnecessary patient exposures and conserve PPE, NMCP has installed telemedicine monitors to be placed in as many patient rooms as possible and at the main nursing station located in the COVID-19 Treatment Unit (CTU). Through the course of a patient’s stay, the majority of markers for improvement [and discharge] such as respiratory rate, supplemental O2 requirement, and fever, can be assessed through telemetry and remote video teleconferencing rather than direct contact.

 

NOTE: Each patient should have an initial admission physical examination upon admission for suspected COVID-19. Telemedicine should be used as an adjunct for daily monitoring and should not be used in lieu of proper examination and clinical judgment.

 

Anatomy of a Cisco Webex DX80

 

Remember: Mute and close the microphone when done and DO NOT END THE CALLINSTEAD, PLACE THE CALL ON HOLD SO THE CONNECTION IS NOT SEVERED.  If you end the call then someone will have to go back into the room to answer a new call next time you want to talk to that patient.  Placing the call on hold (instead of ending it) allows the call to remain connected but inactive, ready to be taken off hold for subsequent use. 

A.   Discharge

 

1.      Discharge Considerations

 

Starting the day of admission begin planning for where the patient will go after discharge and what barriers may unnecessarily extend their hospital stay and thus their risk of iatrogenic complication. 

Ensure they are able to effectively self-isolate at home if needed.

If they are going to a facility on discharge, they will likely need one more negative COVID tests before transfer.  Plan for this early so that the required testing can be complete by the day of discharge.

 

2.      Home Isolation Categories

 

When a patient meets discharge criteria, the provider must then determine a home isolation instruction plan to provide to the patient which corresponds the categories listed below. These categories can be selected on your daily progress notes. You will work with family liaison and discharge planning to ensure the patient has a good home isolation plan in place if needed.   These are important to make clear even if the patient is transferring to another service and not going home immediately.

 

      COVID Positive by PCR or CT scan:  Self isolation until both of the following are true

      Outpatients: 10 days from onset of symptoms or from day of positive test if asymptomatic

      Inpatients: Most will require 20 days from onset of symptoms

1.       This is because most admissions meet criteria of “severe COVID” i.e. O2 sat <94%. The exception would be an admission with COVID for another indication, where they may not have the respiratory features to categorize as “severe COVID.” In this case, 10 days from symptom onset (or 10 days from date of test) is appropriate.

      Both outpatient and inpatient: 1 days without fever, cough, or dyspnea (off of antipyretics)

      COVID Negative, Influenza-Like-Illness (ILI) present:  Self isolation until both of the following are true

       7 days from the day of discharge

      3 days without fever, cough, or dyspnea (off of antipyretics)

      COVID Negative, no respiratory illness: No self-isolation required.

 

3.      Self-Isolation versus Self Quarantine

      Self-Isolation: The patient is completely isolated from the public AS WELL AS members of his/her household.  They stay in their own room with their own bathroom.  Food is left at the door.  They do not have any face-to-face interactions with a human except through video calls and closed windows until isolation ends.  This is for patients with COVID or CLI

      Self-Quarantine: Those with possible exposure to COVID remain in their house for the duration of quarantine.  Household members may interact with each other but must remain separated from public life including visits with/from friends and trips outside the home if possible.  Exposed persons may transmit virus before symptoms or if symptoms never manifest, so social distancing, masks, etc. minimize risk of transmission from persons in quarantine without symptoms.

 

4.      Discharge Instruction Templates

 

When discharging a patient with suspected or known COVID-19 home from the hospital, it is imperative to provide complete and accurate discharge instructions in order to keep both the patient and the public safe. The following are templates to be used for COVID-19 discharges. It is important to include these instructions into discharge summaries, even if the patient is being transferred off the service to another non-COVID-19 unit in the hospital.  These instructions are to be pasted into the Non-Template section of the discharge summary following the typical Hospital Course Summary format. 

*** HOSPITAL COURSE SUMMARY ***

 

On the day of discharge, the patient was tolerating a PO diet, ambulating without difficulty, and hemodynamically stable.  The patient had an opportunity to ask questions and all questions were answered.

 

The patient desired to go home and felt comfortable doing so.

 

Please go to the nearest Emergency Department if experiencing severe headache, dizziness, vision loss, chest pain, palpitations, shortness of breath, coughing up blood, vomiting up blood, abdominal pain, diarrhea, passing bloody stools, passing bloody urine, or any other concerning symptoms that you cannot manage at home, or that cannot wait for a scheduled appointment.

COVID-19 POSITIVE

 

You have tested positive for COVID-19.   We strongly recommend you self-isolate at home until both of the following statements are true:

 

It has been 20 days since your symptoms started, or since the day of your first positive test if you did not have COVID-19 symptoms

 

AND

 

For the day prior to stopping isolation you have not had a fever (defined as temperature over 100.4 F) and your symptoms are much better or resolved.

 

This means NO face-to-face interaction or physical contact with others, including members of your household. Maintain at least 6 feet of distance between members of your household.

 

Your family members and anyone living in your home should remain on self-quarantine (they should not leave the house or interact with people outside the house) for 14 days from the date they most recently had close contact with you.

 

FAMILY QUARANTINE UNTIL:  14 days from time of last contact with you.

 

YOU SHOULD SELF ISOLATE UNTIL AT LEAST: XXXX AND YOU HAVE NO SYMPTOMS FOR 1 DAY

 

IF YOU OR ANY OF YOUR FAMILY MEMBERS DEVELOP NEW OR WORSENING SYMPTOMS CALL THE COVID CALL CENTER AT 757-953-6200

 

RETURN TO FULL DUTY CRITERIA, PROVIDE THIS TO YOUR PRIMARY CARE DOCTOR FOR CLEARANCE TO RETURN TO UNRESTRICTED DUTY STATUS:

 

### NO HEART INJURY OR LIMDU ###

1.       Patient meets return to work criteria plus 2 weeks of exercise limitations (no more than brisk walking) after symptom resolution.

2.       Focused clinical exam by primary care provider without clinically significant findings and normal vital signs.

3.       Privileged provider reviewed inpatient discharge summary to assess for end organ involvement or other significant COVID-19 sequelae. Specific focus should be placed on the assessment of myocardial and pulmonary injury. ECG and cardiac biomarkers should be obtained if not completed during hospitalization. Pulmonary studies should be thoroughly reviewed for evidence of injury or decreased function. If myocardial or pulmonary injury is present, consider expert consultation.

4.       After (1), (2), and (3) above, gradual return to physical activity over two to four weeks. Repeat medical evaluation is only necessary if symptoms develop. If no symptoms, may return to duty

 

### HEART INJURY, STROKE, VENOUS THROMBOEMBOLISM, RESPIRATORY FAILURE, CARDIAC FAILURE, RENAL FAILURE, END-ORGAN FAILURE ###

1.       Return to duty based on expert consultation and case-by-case consideration for retention vs. referral to DES for Active Component (AC) or Line of Duty (LOD) or Medical Retention Review (MRR) for Reserve Component (RC). Pulmonary consultation is recommended 2-4 weeks after discharge for advanced pulmonary support to include high-flow nasal cannula, non-invasive positive pressure ventilation (NIPPV), invasive mechanical ventilation, or extracorporeal life support.
