Health director-general, Dr Noor Hisham Abdullah during press conference on current situation of COVID-19 in our country.

Wondering what medicines are being used in our MOH facilities in treating COVID-19 patients despite no specific approved treatment and vaccines for this disease?

Recently, our Ministry of Health published a guideline on management of COVID-19 (updated 19th October 2020). This write-up aims to provide a quick summary on treatment plan for hospitalised COVID-19 patients.

First and foremost, treatment approaches for COVID-19 is evolving rapidly as we learn more about the disease and this write-up may or may not be applicable in the near future. Thus, it is vital as a healthcare professional to keep ourselves updated on the current approaches practiced, specifically in our country.

For starters, positive COVID-19 patients are categorised based on their symptoms and management plans are tailored according to their clinical stage as below;

Clinical stage
Condition of
COVID-19 Patients
Management Plan
MILD1Asymptomatic
  • No treatment required
2Symptomatic,
No Pneumonia
  • No treatment required
  • Close monitoring of vital signs & oxygen saturation
  • Look out for warning signs & if present, treat as category 4
3Symptomatic,
Pneumonia
  • No treatment required
  • Close monitoring of vital signs & oxygen saturation
  • Treat as category 4 if
    • Age ≥ 50 years
    • ESRF
    • Present with any warning signs
Clinical stage
Condition of
COVID-19 Patients
Management Plan
SEVERE4Symptomatic,
Pneumonia,
Requiring supplemental oxygen
  • Antiviral
    • Favipiravir
    • S/C Interferon Beta
  • Immuno-modulatory
    • Dexamethasone (preferred)
    • Methylprednisolone
    • Others: IV Tocilizumab or Convalescent plasma
  • Thrombo-embolism
    • Prophylactic LMWH Enoxaparin
5Symptomatic,
No Pneumonia
  • Place patient in negative pressure isolation room with ante room OR single room with closed doors OR ICU
  • Non- ventilatory support
    • Simple face mask or non-breathing mask if SpO2<92%
    • Mild ARDS : use High flow nasal cannula
  • Ventilatory support
  • Haemodynamic support
  • Sedation – aim for light sedation 
    • Fentanyl or morphine
    • If additional sedatives required, Propofol or dexmedetomidine
  • Nutritional therapyenteral nutrition
  • Venous thromboprophylaxis – prophylactic LMWH or unfractionated heparin
  • Stress ulcer prophylaxis in risk factors – medical ventilation > 48 hours, coagulopathy, RRT, acute liver failure, high dose steroids
    • No previous GI ulcer: IV Ranitidine
    • Previous GI ulcer or on PPI: IV Pantoprazole, Omeprazole or Esomeprazole
  • Glycemic control – maintain BG 8-10mmol/L using insulin
  • Antivirals and/or Immunomodulating agents
Warning signs predicting deterioration
Clinical
  • Persistent or new onset of fever
  • Persistent lethargy/ anorexia/ cough
  • Exertional dyspnea, RR>25, SpO2 room air <95%
Laboratory
  • Rising CRP value OR CRP ≥ 5mg/dL
Radiological
  • Multi-lobular involvement OR rapidly worsening chest

General care for all COVID-19 patients includes;

General Care for all COVID-19 patients
  • Symptomatic treatment: antipyretic, nutritional support, maintain fluid & electrolytes balance
  • Close monitoring of vital signs
  • Regular blood investigations & imaging
  • No nebulizer, use MDI with spacer bronchodilator
  • No routine antibiotics prescribed
  • No longer using hydroxychloroquine, lopinavir+ritonavir (Kaletra), ribavirin as treatment

To date, the aforementioned therapeutics are only used as off-label for COVID-19 treatment. While we are waiting for more results from clinical trials, let’s continue to abide to the SOPs – physical distancing, wearing face mask & frequent hand washing. #staysafe
