Physical Examination » » Assess vital signs and oxygen saturation via pulse oximetry. » » Pulmonary findings on auscultation have often been unre- markable. Laboratory Testing » » Initial laboratory evaluation should be guided by clinical find- ings. • Consider complete blood count with differential, liver transaminases and inflammatory markers (e.g., erythrocyte sedimentation rate and C-reactive protein), which may be elevated (Layden JE, 2019). • » » Consider conducting urine toxicology testing, with in- formed consent, including testing for THC. Infectious disease evaluation to rule out other etiologies might include • Respiratory viral panel including influenza testing during flu season, Streptococcus pneumoniae, Legionella pneu- mophila, Mycoplasma pneumoniae, endemic mycoses, and opportunistic infections. Imaging » » Chest radiograph (CXR). » » Consider chest computed tomography (CT) for evaluation of severe or worsening disease, complications, other illnesses, or when CXR result does not correlate with clinical findings. » » Radiographic findings consistent with EVALI include pulmo- nary infiltrates on CXR and opacities on CT scan.

WHAT PHYSICIANS CAN DO We need your help! Physicians can play a pivotal role in helping to identify the specific cause of this very serious lung injury while protecting and treating their patients. Here is how you can help: 1. Report cases of lung injury of unclear etiology and a history of e-cigarette or vaping product use within the past 90 days to the Kentucky Department for Public Health using the EPID 200 form and submit via secure fax at 502-696-3803. The illness name can be listed as “EVALI.” Please also include all patient medical records pertaining to the lung injury. Reporting of lung injury cases may help the CDC determine the exact cause. 2. Ask all patients who report e-cigarette, or vaping, product use within the last 90 days about signs and symptoms of respira- tory illness. 3. If e-cigarette, or vaping, product use is suspected as a possible etiology of a patient’s lung injury, obtain detailed history. 4. After contacting the Kentucky Department for Public Health, determine if any remaining product, including devices and liq- uids, is available for testing. Please ship product samples to the Kentucky Division of Laboratory Services, Att: Rachel Zimmer or Leigh Ann Bates, 100 Sower Blvd., Ste 204, Frankfort, KY 40601. Product may include the e-cigarette or vaping device (no lithium batteries), liquid, refill pods and cartridges. These may be shipped in packaging of your choice. They do not fall under DOT hazardous material regulation. 5. Advise adult patients who are using e-cigarettes for smoking cessation not to return to cigarettes but to contact the Depart- ment of Public Health and Wellness at 574-STOP (574-7867). We offer free smoking and vaping cessation classes with FDA approved nicotine replacement products such as patches and gum. This outbreak is evolving quickly and changing rapidly.
