Brian F. Olkowski, DPT; Mary Ravenel, MSN; and Michael F. Stiefel, MD, PhD| April 1, 2018
Following elective lumbar drain placement to treat hydrocephalus and elevated intracranial pressures, a woman was admitted to the ICU for monitoring. After the patient participated in prescribed physical therapy on day 5, she complained of headaches, decreased appetite, and worsening visual problems—similar to her symptoms on admission. The nurse attributed the complaints to depression and took no action. Early in the morning, the patient was found barely arousable. The lumbar drain had dislodged, and a CT scan revealed the return of extensive hydrocephalus.
Christopher Moriates, MD| January 1, 2018
Following a positive fecal immunochemical test (a screening test for colon cancer), a colonoscopy was ordered for a 50-year-old man. Two months later, the nurse called him to see if he had obtained the colonoscopy. The patient reported that he was unable to schedule it due to cost of the copayment. The primary physician called the insurance company and was informed that the colonoscopy would be covered in full if the indication was written as preventive rather than diagnostic. Ultimately, the patient received the colonoscopy and was diagnosed with colon cancer 6 months after his initial positive screening test.
John Q. Young, MD, MPP| June 1, 2016
Multiple transitions and assumptions made during the first week in July, when the graduating fellow had left and a new fellow and intern had begun on the surgery service, led to a patient mistakenly not receiving medication to prevent venous thromboembolism until several days after his surgery.
Carlton R. Moore, MD, MS| August 1, 2012
Drawn on a Thursday, basic labs for a 10-year-old girl came back over the weekend showing a high glucose level, but neither the covering physician nor the primary pediatrician saw the results until the patient's mother called on Monday. Upon return to the clinic for follow-up, the child's glucose level was dangerously high and urinalysis showed early signs of diabetic ketoacidosis.
Isla M. Hains, PhD| June 1, 2012
An elderly woman was transferred to a tertiary hospital for surgical repair of hip fracture, without complete information or records. The receiving surgeons were not informed that she had a cardiac arrest during induction of anesthesia at the community hospital. Surgery proceeded, but the patient died a few days later.
Michelle Mourad, MD, and Stephanie Rennke, MD| March 1, 2012
A woman hospitalized with community-acquired pneumonia was discharged home on antibiotics. Over the next few days, her symptoms worsened, but she was unable to obtain an appointment with her primary physician. The hospital called the patient that day to follow up, determined that she needed a different antibiotic, and prevented a readmission.
Eugene Litvak, PhD, and Sarah A. Bernheim| November 1, 2011
Following hospitalization for suicidality, a woman was discharged to the care of her outpatient psychiatrist, a senior resident who was about to graduate. At her last visit in June before the year-end transfer, the patient was unable to schedule a follow-up visit because the new residents' schedules were not yet in the system. The delay in care had deadly consequences.
Annette J. Johnson, MD, MS| October 1, 2011
When a hospitalized man developed an arrhythmia, the night float resident checked a radiology report that stated the patient had a DVT. Intervention was started based on that assumption. However, the radiology report had been transcribed incorrectly.
Jim Fackler, MD, and Jamie M. Schwartz, MD| October 1, 2011
Residents and nurses assumed an ICU attending was conveying information to the surgeon and cardiologist about a toddler's deteriorating condition after heart surgery. However, none of the providers had a complete picture of the child's status, and he suffered a cardiac arrest.
Steven R. Kayser, PharmD| February 1, 2007
A woman admitted to the hospital for cardiac transplantation evaluation is mistakenly given warfarin despite an order to hold the dose due to an increase in her INR level.
Alan Forster, MD, MSc| December 1, 2004
A patient arrives at the ED in acute kidney failure; another patient arrives at the ED profoundly hypoglycemic. Both mishaps were determined to stem from medication errors at the time of discharge.
