Addressing diagnostic errors to improve outcomes and patient safety has long been a problem in the US healthcare system.¹ Many methods of reducing diagnostic error focus on individual factors and single cases, instead of focusing on the contribution of system factors or looking at diagnostic errors across a disease or clinical condition. Instead of addressing individual cases, KP sought to improve the disease diagnosis process and systems. The goal was to address the systemic root cause issues in systems that lead to diagnostic errors.

During an elective diagnostic cardiac catheterization, the cardiologist unintentionally perforated the patient’s left ventricular wall with the catheter. The cardiologist failed to recognize the perforation, failed to take corrective measures to address the problem, and continued with the cardiac catheterization, including coronary angiographic imaging. Soon after the end of the procedure, the patient complained of severe chest pain and echocardiographic images revealed bleeding around the heart caused by the catheter-related ventricular wall perforation.

With increasing recognition that health is linked to the conditions in which a patient lives, health systems are looking for innovative ways to support recently discharged patients in their lives outside of the hospital. In a recent innovation, Prime Healthcare Services, Inc., which includes a network of 45 hospitals, provided social needs assessments and strengthened its partnerships with community agencies to support the health of high-needs patients after their discharge from the hospital.

A 61-year-old women with a mechanical aortic valve on chronic warfarin therapy was referred to the emergency department (ED) for urgent computed tomography (CT) imaging of the right leg to rule out an arterial clot. CT imaging revealed two arterial thromboses the right lower extremity and an echocardiogram revealed a thrombus near the prosthetic heart valve. The attending physician ordered discontinuation of warfarin and initiation of a heparin drip.

This WebM&M describes two cases involving patients who became unresponsive in unconventional locations – inside of a computed tomography (CT) scanner and at an outpatient transplant clinic – and strategies to ensure that all healthcare teams are prepared to deliver advanced cardiac life support (ACLS), such as the use of mock codes and standardized ACLS algorithms.
