What are the interim recommendations for evaluating suspected vaping-associated lung injury?
If a patient suspects they have lung injury from vaping, the first step is to stop using the product right away and see a doctor. Clinicians should look for specific symptoms like coughing, shortness of breath, and fever. They must also check if the patient used e-cigarettes or vaping products recently. This evaluation helps distinguish vaping-related lung injury from other conditions like pneumonia or asthma.
What the research says
The Centers for Disease Control and Prevention (CDC) issued updated interim guidance for health care providers on how to evaluate and care for patients with suspected e-cigarette or vaping product use-associated lung injury 4. This guidance emphasizes that clinicians should take a detailed history to identify recent vaping product use. It also notes that patients often present with respiratory symptoms such as cough, shortness of breath, and chest pain 2.
Studies of hospitalized cases show that many patients with this condition have a history of using e-cigarettes or vaping products containing THC or other substances 2. The updated clinical guidance advises providers to consider this diagnosis in patients with compatible symptoms and a history of vaping 3. Providers should also rule out other causes of lung injury, such as bacterial pneumonia or aspiration, before confirming the diagnosis 4.
Surveillance data collected as of October 2019 describe the characteristics of patients with lung injury related to vaping products 1. These reports highlight that the injury can occur in people of various ages and that the specific substances in the products may play a role. Clinicians are encouraged to report suspected cases to public health authorities to help track the outbreak and improve understanding of the condition 1.
What to ask your doctor
- What specific symptoms should I look for that might indicate vaping-associated lung injury?
- How soon after vaping did my symptoms start, and does that timing matter for the diagnosis?
- What other conditions, like pneumonia, should be ruled out before confirming this diagnosis?
- Should I stop using all vaping products immediately if I suspect this injury?
- How can I report my case to public health authorities if my doctor confirms the diagnosis?
