Case 2 - To Err is Human
23-year-old in MVA. Fx L fibula and laceration anterior L leg.
Laceration sutured. Dispo home with a return in 3 days for a wound
check. Returned in 4 days. She c/o leg pain and was
triaged to the Fast Track for a wound check.
![Page 20: Double Jeopardy: Risk in Pulmonary](https://reader037.fdocuments.in/reader037/viewer/2022110219/5884f92d1a28abf76f8b79b3/html5/thumbnails/20.jpg)

Case 2 - To Err is Human
In FT, the physician removed the immobilization device, and examined the wound. Documented “Healing well.”
He never looked at the triage complaint, did not visualize the leg beyond the laceration.
In fact it was swollen and tender. She was discharged, but was transported back
to the ED within 12 hours dead on arrival from a saddle embolus.

Case 2
Lawsuit resulted in a $1M settlement for the family.
Key in the litigation was the family testimony about informing the physician regarding increasing leg pain.
Issues: Geography is destiny Anchoring and premature closure

PE Litigation Overview
Failure to recognize, consider or document predisposition to PE.
Failure to explain tachycardia. Pulse temperature disparity. PE masquerading as pneumonia (CXR density
and mild WBC evaluation). Failure to rule out PE in appropriate cases with
a ‘documented’ EB diagnostic approach.

Pneumothorax

without a clear lung edge finding Seen with supine CXRs after blunt or penetrating
trauma, central line placement, and after thoracentesis

Pneumothorax
Occult pneumothorax Negative CXR findings associated with
presence of pneumothorax on CT scan of ABD or Chest
Increased diagnosis linked to liberal CT ordering practice
Overall prevalence is 2-15% Recent multicentered trial comparing
observation vs drainage in mechanically ventilated patients revealed no significant difference in mortality

Pneumothorax
Ultrasound use for suspected pneumothorax Meta-analysis comparing supine Chest x-ray to
bedside point of care Ultrasound: 21 articles; 1,048 patients; CT scan or release of
air on chest tube placement viewed as gold standard for pneumothorax
Chest x-ray was 50.2% sensitive (95% CI, 43.5-57.0) and 99.4% specific (95% CI, 97.0-99.0)
Ultrasound was 90.9% sensitive (95 CI, 86.5-93.0) and 98.2% specific (95% CI, 97.0-99.0)
This study supports the routine use of Ultrasound for the detection of pneumothorax

Occult Pneumothorax Consider the diagnosis in supine films that
sharply demarcate the hemidiaphragm Obtain erect Chest x-rays Consider Ultrasound use focusing on “slide
sign” Encourage return for worsening dyspnea or
chest pain

Solitary Pulmonary Nodules in ED
Defines as: Discrete, well-marginated, rounded opacity Less than or equal to 3 cm in diameter Completely surrounded by lung parenchyma Does not touch the hilum or mediastinum Not associated with adenopathy, atelectasis, or
pleural effusion Lesions larger than 3 cm are considered
masses and are treated as malignancies until proven otherwise.

Solitary Pulmonary Nodules in ED
Upon discharge patient should be referred to PCP for PET scan or CT scan for further work up
The differential diagnosis of a solitary pulmonary nodule is broad and management depends on whether the lesion is benign or malignant.
Increased risks for malignancy include smoking history, size (larger than riskier), spiculated calcification, upper lobe presence

Solitary Nodule Litigation Overview
In most cases, the radiologist sees the nodule and mentions it, the report goes to the PMD who never sees the imaging report from the ED visit.
The solitary nodule is overlooked by radiology, the ED doc gets named, but gets usually gets out of the case.
The nodule is picked up by radiology and mentioned in the report, no f/u arranged by the ED doc and it falls through the cracks.
![Page 61: Double Jeopardy: Risk in Pulmonary](https://reader037.fdocuments.in/reader037/viewer/2022110219/5884f92d1a28abf76f8b79b3/html5/thumbnails/61.jpg)

Solitary Nodule Litigation Overview
On wet read the solitary nodule is not relevant to the presentation, the radiologist mentions it in the report the next AM, the ED doc never sees the reading.
Not picked up on wet read, picked up next AM, and the ED over-read F/U system does not work.
The ED doc sees it on wet read, but does not address it on disposition. There is no PM, the on-call doc never looks at the interpretation.
