Trace & isolate all HCW contacts from CCU, cath, CT (significant exposure)
Swab patient & wait
Result -ve for COVID19
Now what?
1 Ignore PCR result & Isolate ~ 20 people for 2 weeks
2 Swab HCW & isolate only +ve
3 Repeat swab for patient
2/2
What I learned:
🔑Pathways ≠ individualized care
🔑Pre-COVID19 era practices still valid
🔑Treat all as suspected
So:
1 ▶️HCW screened 4 symptoms & isolated (fortunately none did)
cdc.gov/coronavirus/20…
2▶️CT reviewed w radiologist & likely aspiration pneumonia (not COVID19)

Wuhan study
59% (n = 601) had +PCR
88% (n = 888) had + chest CT
75% (n = 308)-PCR w + chest CT
Serial PCR & CT scan
mean 5.1 days -➡️+
mean 6.9 days +➡️-
3▶️ Sputum vs swab
1070 specimens from 205 confirmed COVID
-Bronchoalveolar lavage 93%
-Sputum 72%
-Nasal swabs 63%
-Fibrobronchoscope bx 46%
-Pharyngeal swabs 32%
-Feces 29%
-Blood 1%
? Sample multiple sites ? improve sensitivity &⬇️ reduce false-
