Daren K. Heyland, MD, MSc; April 2017
When a 94-year-old woman presented for routine primary care, the intern caring for her discovered that the patient's code status was "full code" and that there was no documentation of discussions regarding her wishes for end-of-life care. The intern and his supervisor engaged the patient in an advance care planning discussion, during which she clarified that she would not want resuscitation or life-prolonging measures.

Prior to undergoing a CT scan, a patient with no allergies documented in the electronic health record (EHR) described a history of hives after receiving contrast. During a follow-up clinic visit, the patient inquired whether this contrast reaction was listed in the EHR. Investigation revealed that it had been removed from the patient's profile, thus leaving the record with no evidence of allergy to contrast.

Hospitalized with nonketotic hyperglycemia, a man was placed on IV insulin and his blood sugars improved.

Admitted to the hospital with a small bowel obstruction and ileitis consistent with an exacerbation of Crohn disease, a man was given empiric antibiotic therapy and infliximab prior to consultation with gastroenterology. Gastroenterology recommended sending stool studies and initiating infliximab only after those studies were negative for infection. The stool studies were sent, but the primary team did not discontinue the infliximab. The patient was found to have Clostridium difficile infection.

A 21-year-old woman with a history of Marfan syndrome complicated by aortic root dilation presented to the emergency department with abdominal pain and was found to be pregnant. It was her second pregnancy; she had a therapeutic abortion 4 years earlier due to the risk of aortic rupture during pregnancy. At that time, the patient had been advised to have her aortic root surgically repaired in the near future. However, after the patient turned 18, she did not receive regular follow-up care or pre-conception or contraception counseling despite the risk to her health should she become pregnant.

For a man with hypertension, prostate cancer, and chronic kidney disease hospitalized with acute kidney injury, discharge planning created numerous challenges. The inpatient team wanted a 1-week follow up, but the patient was new to this health system and had not yet seen a primary care provider. With the next available appointment in 6 weeks, the patient was instructed to call the urgent care clinic (which offered only same-day appointments) 1 week later. However, he never made it to the clinic and presented to the emergency department 2 weeks later with poorly controlled hypertension.

A woman hospitalized with community-acquired pneumonia was discharged home on antibiotics.

Further investigation revealed that the surgeons had actually walked the patient's roommate, another Cantonese-speaking woman.
