COVID-19, a novel coronavirus (a large family of viruses that can cause cold-like illnesses) first identified in December 2019, is a respiratory illness that can be spread from person to person, possibly through respiratory droplets during close contact. The first case of COVID-19 in the United States was reported on January 21, 2020.
Symptoms and People at Highest Risk
Patients with COVID-19 may have mild to severe respiratory illness with fever, cough, and difficulty breathing, although some report asymptomatic infection. Research is emerging that indicates some cases may present with gastrointestinal upset, loss of taste or smell, or joint pain. Conjunctivitis may also be an early sign of infection. More serious presentations can include severe pneumonia, respiratory failure, and septic shock.
Those at highest risk for infection have had prolonged, unprotected close contact with a patient with confirmed COVID-19 or live in or have recently been to areas with sustained transmission. Based on limited data from COVID-19 and other related coronaviruses, older adults and those with certain underlying medical conditions, including cancer, may be at greatest risk for severe outcomes.
Prevention and Treatment
No vaccine is currently available to protect against COVID-19. The best prevention is to avoid being exposed to the virus and practice good everyday habits:
- Avoid close contact with people who are sick.
- Put distance between yourself and other people outside of your home.
- Avoid touching your eyes, nose, and mouth with unwashed hands.
- Stay at home when you are sick.
- Use a cloth face mask or cover over your mouth or nose when around others outside your home.
- Clean and disinfect surfaces.
- Wash your hands often with soap and water for at least 20 seconds. Use an alcohol-based sanitizer that contains at least 60% alcohol when soap and water are not available.
Supportive care of complications remains the primary clinical focus for patients with COVID-19, because researchers have not identified any specific antiretroviral treatment. However, on May 1, 2020, the U.S. Food and Drug Administration issued an emergency use authorization for remdesivir for the treatment of hospitalized adults and children with suspected or laboratory confirmed COVID-19, and other antiviral agents are being tested. Dexamethasone is also being explored for its anti-inflammatory properties. Not all patients will require medical supportive care.
Oncology Nursing Implications and COVID-19
The COVID-19 pandemic represents an unprecedented time in medicine. The situation and recommendations are constantly evolving and are likely to keep changing as more evidence emerges specific to oncology nursing practice, patients with cancer, and COVID-19. Cancer and COVID-19 data registries suggest that patients with a history of cancer who have confirmed COVID-19 infection appear to be at a higher risk for mortality and severe illness from the virus.
Some key considerations for nursing practice:
- Staff may need additional training to screen patients for COVID-19 symptoms.
- Telehealth visits are a reasonable option for patients with cancer and their caregivers and should be used when appropriate.
- Consider postponing routine follow-up visits for patients not on active treatment or using telemedicine.
- Home infusion may be a possibility for certain patients.
- At this time, treatment delays are not widely recommended for all patients but may be considered by the interprofessional team on a case-by-case basis.
- Review and update any policies and procedures regarding isolation of infected patients.
- If a patient on active treatment is diagnosed with COVID-19, follow standard clinical management recommendations for infection modifications.
- Patients should be educated about COVID-19 symptoms and instructed to call if they develop a new fever, cough, or shortness of breath.
Personal protective equipment (PPE) and availability during the outbreak is a top concern for nurses both in oncology and across the healthcare system. Learn what PPE is required for COVID-19 and how to address shortages.
