Admitted with generalized weakness, nausea, and low blood pressure, an elderly man was given IV fluids and broad spectrum antibiotics. Laboratory test results revealed a mildly elevated white count, acute kidney injury, and elevated liver function tests. The patient was admitted to the medical ICU with a presumed diagnosis of septic shock. His blood pressure continued to trend downward. While reviewing the emergency department test results, the ICU resident noticed the patient's troponin level was markedly elevated and his initial ECG revealed T-wave inversions. A repeat ECG in the ICU showed obvious ST segment elevations, diagnostic of an acute myocardial infarction. The resident realized that the patient's low blood pressure was likely due to the myocardial infarction, not septic shock. He underwent urgent cardiac catheterization and was found to have complete occlusion of the right coronary artery, for which a stent was placed.
An older woman with lung cancer that had metastasized to the brain was admitted to the hospital and found to have Pneumocystis jiroveci pneumonia (PJP pneumonia), invasive pulmonary aspergillus, diffuse myopathy, and gastrointestinal bleeding. Medication reconciliation revealed that she had been prescribed a high dose of dexamethasone to reduce the brain swelling associated with the cancer. Although the intention had been to taper the steroids after she received radiotherapy for her brain metastases, the corticosteroids were never tapered, and she continued to take high-dose steroids for more than 2 months. Physicians believed that all of her acute issues were a result of the mistakenly high dose of the steroids.
An older man with multiple medical conditions and an extensive smoking history was admitted to the hospital with worsening shortness of breath. He underwent transthoracic echocardiogram, which demonstrated severe aortic stenosis. The cardiology team recommended cardiac catheterization, but the interventional cardiologist could not advance the catheter and an aortogram revealed an abdominal aortic aneurysm (AAA) measuring 9 cm in diameter. Despite annual visits to his primary care physician, he had never undergone screening ultrasound to assess for presence of an AAA. The patient was sent emergently for surgical repair but had a complicated surgical course.
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.
After presenting to a rural emergency department with chest pain, a man with a history of diabetes awaited admission to the hospital. The off-site admitting internist ordered aspirin and a heparin drip, but neither medication was administered. On transfer to the acute care unit 2 hours later, the patient was diaphoretic, somnolent, tachycardic, and borderline hypotensive. The nurse called the internist and realized the heparin drip had never been started. When she went to administer it, the patient was unresponsive, hypotensive, and bradycardic. She called a code blue.
An elderly man with a history of giant cell arteritis (GCA) presented to the rheumatology clinic with recurrent headaches one month after stopping steroids. A blood test revealed that his C-reactive protein was elevated, suggesting increased inflammation and a flare of his GCA. However, his rheumatologist was out of town and did not receive the test result. Although the covering physician saw the result, she relayed just the patient's last name without the medical record number. Because the primary rheumatologist had another patient with the same last name, GCA, and a normal CRP, follow-up with the correct patient was delayed until his next set of blood tests.
Although the electronic health record noted that a woman required a Spanish interpreter to communicate with providers, no in-person interpreter was booked in advance. A non–Spanish-speaking physician attempted to use the clinic's phone interpreter services to communicate with the patient, but poor reception prevented the interpreter and patient from hearing each other. The patient called her husband, but he was unavailable. Eventually, a Spanish-speaking medical assistant was able to interpret for the visit. Fortunately, the physician was able to determine that the patient required further cardiac testing before proceeding with a planned elective surgery.
One day after reading only the first line of a final ultrasound result (which stated that the patient had a thrombosis), an intern reported to the ICU team that the patient had a DVT. Because she had postoperative bleeding, the team elected to place an inferior vena cava (IVC) filter rather than administer anticoagulants to prevent a pulmonary embolism (PE). The next week, a new ICU team discussed the care plan and questioned the IVC filter. The senior resident reviewed the radiology records and found the ultrasound report actually stated the thrombosis was in a superficial vein with low risk for PE, which meant that the correct step in management of this patient's thrombosis should have been surveillance.
Admitted with an intracranial mass and hemorrhage, a woman with atrial fibrillation had been stable for several days when the ICU team and neurosurgeon decided that the benefits of low-dose DVT prophylaxis would outweigh the risk of serious bleeding. However, no dose or route of administration was specified, and the overnight resident ordered full-dose (rather than the prophylactic dose) anticoagulation. The hemorrhage grew and brain compression worsened, leaving the patient with no chance for meaningful recovery.
A woman who had been taking naltrexone to treat alcohol use disorder was discharged to a skilled nursing facility (SNF) on opioids for pain following spinal fusion surgery. Although her naltrexone was held at the hospital in anticipation of starting opioids for pain control, the clinician performing medication reconciliation at the SNF overrode the drug–drug interaction alert and restarted the naltrexone. The SNF providers did not realize that the naltrexone blocked the pain-relieving effect of the opioids.
Found unconscious at home, an older woman with advanced dementia and end-stage renal disease was resuscitated in the field and taken to the emergency department, where she was registered with a temporary medical record number. Once her actual medical record was identified, her DNR/DNI status was identified. After recognizing this and having discussions with the family, she was transitioned to comfort care and died a few hours later. Two months later, the clinic called the patient's home with an appointment reminder. The primary care physician had not been contacted about the patient's hospitalization and the electronic record system had not listed the patient as deceased.
An older man admitted for the third time in 4 weeks for an exacerbation of congestive heart failure expressed his wishes to focus on comfort and pursue hospice care. Comfort measures were initiated and other treatments were stopped. The care team wrote for a standing dose of IV hydromorphone every 4 hours. The night shift nurse administered the scheduled dose at 3:00 AM. At 7:00 AM, the palliative care attending found the patient obtunded, with shallow respirations and a low respiratory rate.
A Spanish-speaking woman presented to an urgent care clinic complaining of headache and worsening dizziness, for which the treating clinician ordered an MRI. When the results came in with no concerning findings later that day, the provider used Google Translate to write a letter informing the patient of the results. The patient interpreted the letter to mean that the results were concerning. This miscommunication led to patient distress and extra visits to both urgent care and the emergency department.
An older man with Crohn disease was admitted for abdominal pain and high stool output from his ileostomy. Despite blood passing from his ostomy and a falling hemoglobin level, the patient was not given a timely blood transfusion.
Admitted to gynecology due to excess bleeding and low hemoglobin after elective surgery, an older woman developed severe pain, nausea, and new-onset atrial fibrillation. She was moved to the telemetry unit where cardiologists treated her, and she had episodes of bloody vomit. Intensivists consulted, but the patient arrested while being transferred to the ICU and died despite maximal efforts.
Following an uncomplicated surgery, an older man developed acute colonic pseudo-obstruction refractory to conservative management. During a decompression colonoscopy, the patient's colon was perforated.
To avoid worsening acute kidney injury in an older man with possible mesenteric ischemia, the provider ordered an abdominal CT without contrast, but the results were not diagnostic. Shortly later, the patient developed acute paralysis, and an urgent CT with contrast revealed blockage and a blood clot.
Emergency department evaluation of a man with morbid obesity presenting with abdominal pain revealed tachycardia, hypertension, elevated creatinine, and no evidence of cholecystitis. Several hours later, the patient underwent CT scan; the physicians withheld contrast out of concern for his acute kidney injury. The initial scan provided no definitive answer. Ultimately, physicians ordered additional CT scans with contrast and diagnosed an acute aortic dissection.
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.
Brought to the emergency department from a nursing facility with confusion and generalized weakness, an older woman was found to have an elevated troponin level but no evidence of ischemia on her ECG. A consulting cardiologist recommended treating the patient with three anticoagulants. The next evening, she became acutely confused and a CT scan revealed a large intraparenchymal hemorrhage with a midline shift.
A few weeks after falling and hitting her head, a woman with metastatic cancer was admitted to the hospital for observation after a brain scan showed a subdural hematoma with a midline shift. Repeat imaging showed an enlarging hematoma, which required surgical evacuation. The admitting provider had mistakenly prescribed blood thinner for venous thromboembolism prophylaxis (contraindicated in the setting of subdural hematoma) by clicking the box in the electronic health record admission order set.
Following a hysterectomy, a woman was discharged but then readmitted for pelvic pain. The radiologist reported a large pelvic abscess on the repeat CT scan, and the gynecologist took the patient to the operating room for treatment based on the report alone, without viewing the images herself. In the OR, the gynecologist could not locate the abscess and stopped the surgery to look at the CT images. She realized that what the radiologist had read as an abscess was the patient's normal ovary.
A young woman with a history of suicide attempts called her primary care physician's office in the morning saying that she had been cutting herself and had taken extra doses of medication. The receptionist scheduled the patient for an appointment late that afternoon. After the clinic visit, while awaiting transfer to the emergency department for evaluation and admission, the patient was left unattended and eloped before providers could evaluate her.
After an emergency cesarean delivery, a woman had progressive tachycardia and persistent hypertension. A CT scan showed no evidence of pulmonary embolism, but repeat blood tests showed a dangerously low hemoglobin level and markedly elevated liver enzyme levels. She was taken back to the operating room and found to have postpartum hemorrhage.
While attempting to order a CT scan with only oral contrast for a patient with poor kidney function, an intern ordering a CT for the first time selected "with contrast" from the list, not realizing that meant both oral and intravenous contrast. The patient developed contrast nephropathy.
An elderly woman with multiple medical conditions experienced new onset dizziness and lightheadedness. A home visit revealed numerous problems with her medications, with discontinued medications remaining in her pillbox and a new prescription that was missing. In addition, on some days she was taking up to five blood pressure pills, when she was supposed to be taking only two.
Admitted to the intensive care unit (ICU) with acute respiratory distress syndrome due to severe pancreatitis, an older woman had a central line placed. Despite maximal treatment, the patient experienced a cardiac arrest and was resuscitated. The intensivist was also actively managing numerous other ICU patients and lacked time to consider why the patient's condition had worsened.
An older man with multiple medical conditions was found hypoxic, hypotensive, and tachycardic. He was taken to the hospital. Providers there were unable to determine the patient's wishes for life-sustaining care, and, unaware that he had previously completed a DNR/DNI order, they placed him on a mechanical ventilator.
Multiple alarms went off in an ICU room after an intern and resident performed paracentesis on an older patient. Nurses found the patient confused and trying to get out of bed. She had pulled out her nasogastric and endotracheal tubes, her leg was stuck in the bedrails, and she had a large cut on her foot.
While hospitalized, a man with diabetes had difficult-to-control blood sugars, with multiple episodes of both critical hypoglycemia and serious hyperglycemia. Because "holds" of the patient's insulin were not clearly documented in the electronic health record and blood sugar readings were not uploaded in real time, providers were unaware of how much insulin had actually been given.
Despite mechanical problems with the robotic arms during a robotic-assisted prostatectomy, the surgeon continued using the technology and completed the operation. Following the procedure, the patient developed serious bleeding requiring multiple blood transfusions, several additional surgeries, and a prolonged hospital stay.
Admitted to the hospital for chemotherapy, a man with leukemia and diabetes arrived on the medical unit on a busy afternoon and waited until his room was ready. The nurse who checked him in assumed that his admitting orders were completed on the previous shift. That night, the patient took his own insulin from home without a meal and experienced a preventable episode of hypoglycemia.
Following a non-ST segment elevation myocardial infarction, a man was admitted to the hospital and placed on a telemetry monitor. As the monitor was constantly sounding with "low voltage" and "asystole" alerts and the patient was well each time clinicians checked, they silenced the alarms. The patient was found dead 4 hours later.
The Risks of Absent Interoperability: Medication-Induced Hemolysis in a Patient With a Known Allergy
After leaving Hospital X against medical advice, a man with paraplegia presented to the emergency department of Hospital Y with pain and fever. The patient was diagnosed with sepsis and admitted to Hospital Y for management. In the night, the nurse found the patient unresponsive and called a code blue. The patient was resuscitated and transferred to the ICU, where physicians determined that the arrest was due to acute rupturing of his red blood cells (hemolysis), presumably caused by a reaction to the antibiotic. Later that day, the patient's records arrived from three hospitals where he had been treated recently. One record noted that he had previously experienced a life-threatening allergic reaction to the antibiotic, which was new information for the providers at Hospital Y.
After several days of abdominal pain, nausea, and vomiting, a pregnant woman visited the emergency department and was swiftly discharged with antibiotics for a UTI. However, she returned the next day with unchanged abdominal pain and more nausea and vomiting. Apart from a focused ultrasound to document her pregnancy, no further testing was done. The patient again returned the following day with increased pain and now appeared more ill. An MRI revealed a ruptured appendix.
