2 ACTION PLAN 13: CASE MANAGEMENT

The following action plan is recommended for hospitals AT THIS STAGE by the Consultancy Panel while preparing

for the COVID-19 Pandemic.

This technical advice document must be read in conjunction with the National Health Plan for COVID-19

(National Dept of Health, 7 May 2020) and COVID-19 Health Care Surge Strategy (National Dept of Health, 30

April 2020).

DISASTER MEDICINE CSCATTT ALGORITHM1

C: Command and Control S: Safety C: Communication A: Assessments T: Triage T: Treatment Case Management

The various steps of this Algorithm will be addressed in the follow-up Action Plans.

3 INTRODUCTION

This Action Plan is focused on preparing the facility for providing clinical care to patients with COVID-19. It is

based on the Guideline: Clinical Management of Suspect or Confirmed COVID-19 (Currently Version 4) (National

Dept of Health and NICD, 18 May 2020).

This Action Plan does not cover triage of patients, as this is covered in Action Plan 10. All patients must be

streamed or divided into suspected/confirmed Covid-19 cases and non-Covid-19 cases at the entrance to the

hospital. Thereafter, all suspected suspected/confirmed Covid-19 cases should be triaged to receive one of the

four packages of care which are outlined in this action plan.

The four packages of care are:

• Mild disease

• Moderate disease

• Severe/critical disease

• Palliative care

It should be noted that these definitions are not fully aligned with those used by the World Health Organization

in their clinical guidelines. The simplified approach was chosen as it aligns more closely with the South African

1 (Advanced Life Support Group, 2019)

4

Clinical Guidelines as well as levels of care within the South African health system (home/low care bed, standard

hospital bed, critical care (ICU and high care) which have also been used in other components of planning.

The overview of all four care packages is shown in Annexure A, whilst each care package is discussed individually

in the following four sections. Hospitals primarily need to prepare to provide inpatient care to patients with

moderate and severe disease. Patients with mild disease may be seen and managed in outpatient departments.

Clinical management of patients with Covid-19 remains relatively straightforward, but is dependent on

availability of sufficient trained personnel and adequate supplies of:

• Infrastructure, beds and equipment

• Oxygen and other respiratory support

• Medicines

• Consumables

• Personal Protective Equipment (PPE)

This action plan includes some information on oxygen and other respiratory support, medicines and

consumables.

Provision of oxygen and other respiratory support remains the cornerstone of clinical care for patients with

Covid-19. Whilst a standard approach to provision of increasing concentration and flow rate of oxygen remains

relevant in Covid-19 disease, provision of non-invasive ventilation appears to be more beneficial than previously

thought. For this reason, information on provision of High Flow Nasal oxygen is described in some detail. The

section on Oxygen and Respiratory Support should be read in conjunction with Action Plan 11 which includes

information on delivery of oxygen.

Hospitals must also plan for the increased quantities of medicines and consumables that are likely to be required

in increased volumes during the Covid-19 surge.

4 MILD DISEASE: PACKAGE OF CARE

The majority of symptomatic Covid-19 patients will present with mild disease. The criteria for mild disease are

shown in Error! Not a valid bookmark self-reference. and are:

• SpO2 ≥95% on room air

• Respiratory rate <25

• Heart rate <120

• Temp 36-39°C

• Mental status normal

Advice on self-isolation at home

Patients with mild disease do not require in-patient (hospital) care; they require basic nursing care (also termed low level care in the Surge plan document). However, they must be isolated from others – this can be achieved through self-isolation at home, or, where necessary, through admission to an isolation facility. Patients who are self-isolating should monitor their symptoms are on a daily basis and be able to access medical care if their condition deteriorates. It may necessary to admit patients with mild disease who do not meet these criteria, especially where they are at high risk for developing severe disease. Attention should be paid to ensuring that any co-morbid conditions (especially diabetes and hypertension) are optimally controlled, and that patients have access to an adequate supply of medication. Patients with Covid-19 may not be regular users of health services and their interaction with the health service should also be used as an opportunity to screen for other conditions especially HIV and TB.

5 MODERATE DISEASE: PACKAGE OF CARE

The main characteristic of patients with moderate disease, is their requirement to receive oxygen. All levels of

hospitals are therefore required to ensure that they have sufficient beds each with a reliable supply of oxygen.

Whilst it is recommended that patients with moderate disease are admitted to established/permanent

hospitals, they can also be cared for in field hospitals, providing a reliable supply of oxygen is available.

KEY RESOURCES Clinical management of suspected or confirmed COVID-19 disease V4 COVID-19 Disease: Infection Prevention and Control Guidelines V2 Adult Essential Medicine List Standard Treatment Guidelines.

Medical treatment

In addition to oxygen, all hospitalised patients should receive a ten-day course of Dexamethasone (6mg IV daily

for 10 days) or equivalent corticosteroid. All hospitalised patients should also receive low-molecular weight

heparin. Admitted patients should receive prophylactic doses (e.g. enoxaparin 40mg subcutaneously daily).

Morbidly obese and patients with renal failure may require dose adjustments (consult Adult Hospital EML

Standard Treatment Guidelines). However, patients who require mechanical ventilation or supplemental

oxygen at ≥ 60% oxygen concentration as well patients with serum D-dimers greater than 6-times the upper

limit of normal should receive therapeutic doses of LMW heparin (e.g. enoxaparin 1mg/kg subcutaneously 12-

hourly).

Antibiotic therapy is not routinely recommended but should be provided if secondary bacterial infection is

suspected. Antibiotic therapy should be provided in line with the Essential Medicine List (EML) Standard

Treatment Guidelines.

Attention should be paid to control of hypertension, diabetes, asthma and other underlying conditions. The

acute illness as well as administration of dexamethasone may exacerbate hyperglycaemia in diabetic patients

requiring careful monitoring and appropriate treatment (see EML STG).

7

Monitoring

Monitoring of oxygenation using pulse oximetry is critical. Laboratory tests may be needed to exclude other

causes of pneumonia and to monitor for complications.

Referral

Most patients with moderate disease will be cared for in district hospitals. However, a proportion of patients

will deteriorate. Timely identification and referral of patients who are likely (and eligible) to require critical care

is desirable, especially as transport of critically ill patients is associated with poor outcomes.

Radiological findings have been found to be a predictor of a poor outcome, but have not been validated in South

Africa. Where referral is difficult, provision of HFNO outside of critical care settings (including in district hospitals)

should be considered.

Earlier referrals to higher levels of care may be considered in resource poor

or remote settings where difficulties in oxygenation occur or delays in

referral are anticipated.

8

SEVERE DISEASE: PACKAGE OF CARE

Patients who develop severe acute respiratory syndrome or hypoxaemic respiratory failure should ideally be

admitted to a critical care bed in a high care or intensive care unit. Most patients will require ventilation either

mechanical or non-mechanical. As noted above, HFNO appears to play a role in reducing the need for mechanical

ventilation.

6 PALLIATIVE CARE: PACKAGE OF CARE

A number of groups of patients will require palliative care including palliative care patients who are diagnosed

with Covid-19, patients who are not eligible for ventilation and patients where ventilation is withdrawn due to

a lack of response. The palliative care package should focus on management of symptoms, end-of-life care and

7 RESPIRATORY SUPPORT INCLUDING PRONING AND HIGH FLOW NASAL OXYGEN

Oxygen remains the main supportive treatment for COVID-19. It is therefore essential that facilities plan for the

administration of oxygen and respiratory support to nearly all moderate, severe and critical COVID-19 patients.

The National Incident Management Team for COVID-19 has recommended that ONLY PATIENTS REQUIRING

OXYGEN should be admitted to general hospital beds and that mild patients not in need of oxygen (at the

time) could be admitted to temporary facilities or surge facilities at hospitals, that are not equipped for

oxygen administration.

• Mask administration. Most patients will initially require administration of 40% oxygen with a mask.

(Certain comorbidities may indicate lower percentage oxygen administration.) Facilities must therefore

plan for an adequate stock of 40% oxygen masks. Although it is expected that most of the patients will

be adults, current figures indicate that paediatric masks will also be necessary.

• Patients unfortunately desaturate very quickly requiring non-rebreather mask oxygenation. It is

therefore essential that all hospitals plan for non-rebreather masks with a reservoir bag.

10

• There are limited use for nebulised drugs. Precautions is necessary in administering nebulisation due

to the theoretical possibility that the vapour may carry exhaled droplets, especially when patients

cough. A N-95 mask and visor is recommended for staff supporting a patient during nebulisation. Ensure

effective decontamination of nebulisers if it must be moved between Covid and non-Covid areas (not

recommended at all).

• Some experiments were done with nasal prongs at 15 l and a non-rebreather mask over the prongs also

at 15 l from a second flowmeter. This technique dries the nasal mucosa. However, it is recommended

that hospitals plan for this double flowmeter technique for an emergency.

• Continuous Positive Airway Pressure (CPAP) and Bilevel Positive Airway Pressure (BiPAP). Mask or

helmet administered CPAP or BiPAP is a simple technique that can be used in many facilities to manage

COVID-19 on condition that the necessary supervision and observation is available. Hospitals should

plan to have this capability available2.

• High Flow Nasal Oxygen (HFNO) is a technique where a high flowrate of humidified warmed oxygen is

administered via a nasal canula. These apparatuses require electricity at the bed side and can use an

oxygen flow of up to 60 l/min. The flowrate is not generally available at ward-level oxygen outlets. This

technique has shown high success rates in Europe and in the Western Cape – hospitals are therefore

urged to plan for spaces in the hospital where this type of apparatus can be utilised with the required

oxygen flow. Although in general HFNO would generally be provided in a critical care setting, it may be

provided in a standard care setting providing adequate staff, PPE and monitoring are available.

It is essential to take note that the use of several high flow nasal oxygen units and possibly CPAP

units in the same venue may lead to a build-up of the ambient oxygen concentration in the room

due to wasting during exhalation, causing an increased fire risk.

The use of a natural well-ventilated venue (open windows) is strongly recommended.

Ensure that fire extinguishers in the areas are serviced and staff trained to use it.

Staff must also be orientated where to turn off oxygen supply to an area in the event of a fire.

7.1 HFNO DEVICE

High-flow nasal cannula (HFNC) oxygen therapy is a technique configured to deliver adequately heated and

humidified medical gas at a high flow rate. The device consists of a flow generator (providing gas flow rates up

to 60Lmin), an air-oxygen blender (that reliably achieves escalation of FiO2 from 0.21-1.0 at user selected flow

rates), and a humidifier that humidifies the gas mixture at temperatures of between 31-37°C (adjusted to patient

comfort). To minimize condensation, the heated humidified gas is delivered via heated tubing through nasal

prongs or cannula. The device is demonstrated in Figure 1.

2 A national project is underway to supply high numbers of these apparatuses to hospitals.

7.2 ADVANTAGES

HFNC is considered to have a number of physiological effects including:

• low levels of positive end-expiratory pressure (PEEP), at best up to 10 cm H20, that may assist in

increasing lung volume and recruitment of alveoli;3,4

• reduction of anatomical dead space as the high flow washes out CO2;5

• maintenance of a constant FiO2 as the difference between inspiratory flow and delivered flow is small;6

• adequate humidification contributing to good muco-ciliary function and patient comfort;7 and

• decreased work of breathing.8

Other general advantages in COVID-19 patients include that it:

• may be implemented and managed by non-ICU specialists outside ICU;

• does not require invasive monitoring;

• does not need as intensive nursing care as for invasive ventilation;

• can be combined with awake self-proning;

• may be a lower-resource alternative to mechanical ventilation in some patients;

• Is relatively well tolerated and not too cumbersome allowing patient self-care or assisted care while

applying the therapy, including daily functions such as eating.

7.3 CONCERNS

The two main concerns relate to the risk of aerosolization and the adequacy of oxygen supplies. All respiratory

therapy has the potential to create aerosols. A caution with HFNC initially arose because of a concern for possible

generation of droplets and aerosols created or propelled by oxygen therapy via this delivery system with a

consequent increased risk of disease transmission. Subsequent research has indicated that this risk is extremely

low. Dispersion studies have shown that, compared to oxygen therapy with a mask or standard nasal cannulae

at 5 L/min, the utilization of HFNC is no riskier with respect to either dispersion or microbiological contamination

into the environment.9,10 The risk may be further mitigated by the additional application of, for example, a

surgical mask to the patient.

As high flows (up to 60L/min) are used with HFNC systems, a concern rose on the adequacy of hospital oxygen

supplies if the therapy was applied to a large number of patients within the same facility. The high flow of oxygen

exceeds the requirements for routine general ward beds (4-15L/min), and for ICU or ventilated patients

(30L/min).11 This concern relates to storage and delivery of oxygen, and questions the ability of banks or storage

tanks for liquid oxygen to cope with demand in maintaining a constant flow and pressure to reticulation and

supply points. Medical engineering consultation is required about oxygen supply at individual hospitals including

number of HFNC units that can be supported.

7.4 INDICATIONS

For patients who are deteriorating or not improving on conventional oxygen therapy and supportive care, but

who do not appear to be in imminent danger of collapse, HFNC oxygen therapy likely offers benefit. Consider

HFNC in awake, co-operative patient if SpO2 <92% despite O2 15L/min.

Initiation of HFNC does not by default imply that a patient’s care will be escalated to invasive ventilation. Certain

patient groups will be reasonably triaged to receive HFNC as their last escalated oxygen therapy intervention.

These decisions should be made in accordance with local facility triage team protocols as well as national

guidelines (e.g. the CCSSA triage guidelines).

7.5 CONTRAINDICATIONS

• Patients with hypercapnia (exacerbation of obstructive lung disease), haemodynamic instability, multiorgan

failure or abnormal mental status should generally not receive HFNC oxygen therapy in place of other

options such as invasive ventilation.

• Adults with emergency signs (obstructed or absent breathing, severe respiratory distress, central cyanosis,

shock, coma and/or convulsions) should receive emergency airway management and O2 therapy during

resuscitation to target SpO2 ≥ 94% .12

7.6 USE13

• Discuss early with ICU team to ascertain ceilings of treatment at presentation in order to avoid inappropriate

escalation of ventilatory support.

• Ideally HFNC O2 therapy should be applied in single negative pressure rooms. If unavailable, then cohorting

of patients requiring HFNC in designated wards is an alternative.

• Appropriate administrative controls need to be in place

• Ensure adequate environmental ventilation of at least 12 air changes per hour, equivalent to a room with

door and windows open or suitable extraction or air conditioner to achieve same, or with HEPA (high

efficiency particulate air) filtration if recirculated air.

• Personal protective equipment (PPE), including N95/ FFP2 respirators, to be worn by the staff to reduce

nosocomial infections.

• Ensure proper size and fit of nasal cannula. Most interfaces come with a lanyard and two clips to secure

the piping to the hospital gown or pillow. If not, tape to the cheeks so prongs do not leave the nostrils.

• A surgical face mask should be placed on the patient at all times to reduce bioaerosolisation.

• Effective HFNC may rely on patient being able to keep their mouth closed and maintain nasal breathing to

ensure best performance of the device as mouth opening decreases the PEEP effect. Patient training may

be important in achieving the best result.

• Patients should be monitored with continuous pulse oximetry to enable monitoring of response and for

early identification of rapid deterioration.

• Initial settings: Flow 50-60L/min and FiO2 0.8-1.0, titrated to aim initially for SpO2 >90% are recommended.

• Where hospital oxygen supply is constrained, consider using minimum O2 flow necessary to maintain SpO2.

Titrate FiO2 to maximum support prior to increasing flow greater than 35L/min.

• Patients receiving a trial of HFNC should be in a monitored setting and cared for by personnel experienced

with HFNC and capable of performing endotracheal intubation in case the patient acutely deteriorates or

does not improve after a short trial (about 1 hour).

• Once HFNC has been initiated, need to assess the patient regularly to determine if the patient needs to be

intubated.

• There should be a low threshold for intubation where there is clinical decline (which may include a rising O2

requirement, consistently or rapid increase in respiratory rate, consistently or rapidly declining SpO2,

increased work of breathing/exhaustion, and altered mental state).

Intubation should not be delayed if the patient acutely deteriorates or does not improve after a short trial.

10 SUMMARY

Treatment facilities required for COVID-19 can be summarised as standard medical pneumonia care facilities.

However, a few areas requiring special attention are:

• Proning patients

• Oxygen needs

• Palliative care needs

• Psycho-social support needs

This action plan will be followed by a sequentially

numbered Action Plan continuing the preparation

Critical care bed Ideally provided in a structured supported environment where supporting services for critical care are already established. Where resources allow, HFNO and CPAP should be provided in a general bed.

Signs of SARS / severe hypoxaemic respiratory failure: - Respiratory rate > 40 - SpO2 less than 90% or an

arterial blood sample with PaO2 < 8.0 kPa (while using a 40% facemask)

- Heart rate > 120 beats per minute

High-flow nasal oxygen (HFNO), continuous positive airway pressure (CPAP) or other non-invasive ventilation Mechanical ventilation (if indicated) Specific therapy; - Dexamethasone - Others as part of clinical trials Management of complications including co-infection, thrombosis, etc. Intensive care monitoring Supportive care including anti-coagulation (with LMW heparin), fluid management, relief of pain/other symptoms, specialised nutrition support Physiotherapy Infection control and prevention measures

Transfer to standard care bed once extubated/stable for ongoing care and rehabilitation

Consider withdrawal of care and transfer to palliative care bed if condition deteriorates/poor response to critical care.
