After an emergency department (ED) physician interpreted results of a point-of-care ultrasound as showing stable low ejection fraction, some volume overload, and a mechanical mitral valve in place without regurgitation for a man with a history of congestive heart failure, end-stage renal disease, and mechanical mitral valve replacement who presented with shortness of breath, the patient was admitted with a presumed diagnosis of volume overload. Reassured by the ED physician's interpretation of the ultrasound, the hospitalist ordered no further cardiac testing. The patient underwent hemodialysis, felt better, and was discharged. Less than 12 hours later, the patient returned critically ill and in cardiogenic shock. An emergency transthoracic echocardiogram found a thrombosed mitral valve, which had led to acute mitral stenosis and cardiogenic shock.

Admitted to the hospital with an ulcer on his right foot, a man with diabetes and stage IV chronic kidney disease had an MRI concerning for osteomyelitis, and a bone biopsy showed chronic inflammation with cultures positive for methicillin-sensitive Staphylococcus aureus. To administer outpatient parenteral antimicrobial therapy, interventional radiology attempted to place a peripherally inserted central catheter (PICC) in the right brachial vein multiple times but failed. They then placed it in the left brachial vein. The patient completed 6 weeks of antibiotic therapy and wound care, and the PICC was removed. Five months later with worsening renal function and hyperphosphatemia, the patient required dialysis access, but he was not a candidate for arteriovenous fistula placement since the many venipuncture attempts during PICC placement resulted in poor vein quality.

A young adult with a progressive neurological disorder presented to an emergency department from a nursing home with a dislodged GJ tube. As a workaround to maintain patency when the GJ tube was dislodged, nursing home staff had inserted a Foley catheter into the ostomy, inflated the Foley bulb in the stomach, and tied the distal portion of the catheter in a loose knot. When the patient went to interventional radiology for new GJ tube placement, clinicians found no Foley but inserted a new GJ tube. Discharged to the nursing home, the patient was readmitted 2 days later with fever and increasing abdominal distention. An abdominal CT scan showed an obstructing foreign body in the small bowel.
