Short Notes of Triage, Critical Covid-19 and D-Dimer


Clinical triage includes a system for assessing suspected COVID-19 cases having respiratory tract infection with exposure history at outdoor or admission site to allow early recognition of possible COVID-19 patients and immediate separation or isolation of suspected COVID-19 patients from other patients (source control).


  • To facilitate the early identification of suspected COVID-19 case
  • Separation of suspected COVID-19 from general patients

Target population:

  • Patient with COVID-19 like clinical features (fever, cough with or without respiratory distress)
  • COVID-19 suspected case


  • Nurse/outdoor staff/ward boy for initial screening
  • Physician for consultation and management
  • Ticket counter staff
  • Cleaners
  • security staff

Logistic Required:

  • Thermometer;
  • Masks for all cases;
  • Disposable towels;
  • Biohazard bags with bin;
  • Personal protective equipment for health care staffs according (gloves, masks and/or respirators, gowns);
  • Hand hygiene supplies (Soap-water or hand sanitizer).


  • A well-ventilated separate triage room;
  • Sitting arrangement (preferably at least 2 meter distance);
  • Dedicated wash basin with hand wash facilities; Dedicated entrance from outdoor/emergency to triage room and exits;
  • Ticket counter;

Critical Covid-19

Critical Covid-19:

Cases requiring ICU support is called critical Covid. Severe COVID-19 case meeting any of the following criteria is critical Covid:
  • Respiratory failure and requiring mechanical ventilation.
  • Sepsis
  • Septic shock
  • ARDS
  • Any organ failure that requires ICU care


(Sever Case 4 Management )



A D-dimer test is a blood test that can be used to help rule out the presence of a serious blood clot.


  • DVT;
  • Pulmonary embolism;
  • DIC;
  • Stroke.


If the result is "negative," that meant most likely don't have a problem with blood clots, such as DVT. If the result is "high," it means need more testing to see where have a blood clot. This test can't confirm that have DVT or PE. It can only help rule them out.
