Management of COVID-19 Positive Patient
For hospitalized COVID-19 patients, immediately isolate the patient, initiate prophylactic anticoagulation with LMWH, start remdesivir if requiring oxygen (with dexamethasone 6 mg daily for 10 days), and avoid routine antibiotics unless bacterial superinfection is clinically evident. 1
Initial Assessment and Risk Stratification
Severity classification is the critical first step that determines your entire management pathway 1:
- Moderate disease: SpO2 ≥94% on room air with evidence of lower respiratory disease 1
- Severe disease: SpO2 <94% on room air 1
- Critical disease: Requires ICU admission, mechanical ventilation, ARDS, or septic shock 1
Obtain chest imaging (CT preferred over X-ray) during initial assessment to evaluate pneumonia severity and rule out complications like pulmonary embolism 2, 3
Immediate Isolation and Infection Control
Isolate confirmed COVID-19 patients immediately from negative patients to prevent nosocomial transmission 2, 1
Healthcare workers must use complete PPE including N95 masks, goggles, double gloves, face shields, and protective gowns when caring for COVID-19 patients 2
For hospitalized patients, maintain isolation for at least 2 weeks from first positive test and until negative RT-PCR is obtained 2
Pharmacological Management by Severity
For Moderate Disease (SpO2 ≥94% on Room Air)
Start remdesivir 200 mg IV loading dose on Day 1, then 100 mg IV daily for 5 days 1, 4
- May extend to 10 days if no clinical improvement 4
- Perform hepatic laboratory testing before starting and monitor during treatment 4
- Determine prothrombin time before starting and monitor as clinically appropriate 4
Do NOT give corticosteroids to patients not requiring oxygen - this can be harmful 1
For Severe Disease (SpO2 <94% on Room Air)
Administer dexamethasone 6 mg daily for 10 days in addition to remdesivir 1
Provide supplemental oxygen to maintain SpO2 above 90-96% 3
Position patient upright to improve ventilatory capacity 3
For Critical Disease (ICU/Mechanical Ventilation/ECMO)
Continue remdesivir for 10 days total duration 4
Continue dexamethasone 6 mg daily for 10 days 1
Monitor for common complications including ARDS, shock, myocardial dysfunction, acute kidney injury, arrhythmia, and secondary infections 1
Universal Inpatient Interventions
Anticoagulation (Critical - Do Not Delay)
Start prophylactic LMWH for all hospitalized COVID-19 patients as soon as possible 1
Dose based on renal function, bleeding risk, and weight 1
Antibiotic Stewardship
Do NOT routinely prescribe antibiotics 1
Only initiate antibiotics when clinically justified based on:
- Disease manifestations suggesting bacterial superinfection 1
- Imaging findings consistent with bacterial pneumonia 1
- Laboratory data supporting bacterial infection 1
If empirical antibiotics are started, target to culture results and de-escalate as soon as possible 2
Common pitfall: Using biomarkers alone to decide antibiotic initiation - this should be avoided 1
Respiratory Support Considerations
For patients requiring high-flow nasal cannula: patient should wear mask during treatment 5
Use dual-limb ventilators with filters at outlets for mechanically ventilated patients 5
Avoid T-piece for spontaneous breathing trials; use PSV mode instead 5
Monitoring and Follow-up
Monitor continuously for:
- Oxygen saturation and respiratory rate 3
- Signs of respiratory failure requiring advanced support 3
- Hepatic function while on remdesivir 1, 4
- Thromboembolic complications 3
- Secondary bacterial or fungal infections 1
Serial chest imaging to monitor disease progression 3
Special Populations and Considerations
Non-Hospitalized High-Risk Patients
For outpatients with mild-to-moderate COVID-19 at high risk for progression:
- Remdesivir 200 mg IV Day 1, then 100 mg IV daily for 3 days total 4
- Must be initiated within 7 days of symptom onset 4
- Requires setting with immediate access to treat anaphylaxis and activate EMS 4
Surgical Patients with COVID-19
Require multidisciplinary management approach 2
After emergency surgery, re-admit severe pneumonia patients to COVID-ICU 2
Stable asymptomatic/mild symptomatic patients should go to dedicated COVID surgical ward 2
Critical Pitfalls to Avoid
- Delaying anticoagulation - start LMWH immediately 1
- Giving corticosteroids to patients not requiring oxygen - harmful 1
- Routinely prescribing antibiotics - increases resistance 1
- Using biomarkers alone for antibiotic decisions - requires clinical correlation 1
- Forgetting hepatic monitoring with remdesivir - mandatory 1, 4
- Inadequate PPE for healthcare workers - complete protection required 2, 1
