Delays in diagnosis and treatment during after-hours care pose serious threats to patient safety. This case-control study compared missed acute coronary syndrome (ACS) cases to other cases with chest discomfort occurring during out-of-hours services in primary care. Predictors of missed ACS included the use of cardiovascular medication, non-retrosternal chest pain, and consultation of the supervising general practitioner.
This Primer provides an overview of the history and current status of the patient safety field and key definitions and concepts. It links to other Patient Safety Primers that discuss the concepts in more detail.

This direct observation study of hospitalist teams on rounds and conducting follow-up work examined the interaction between systems problems and cognitive errors in diagnosis. Researchers found that information gaps related to electronic health records, challenges with handoffs, and time constraints all contributed to difficulties in diagnostic cognition. The authors suggest considering both systems and cognitive challenges to diagnosis in order to promote safety.
Most patient interactions with the health care system occur in the outpatient setting. Many potential and actual safety problems occur there as well.(1) Yet patient safety literature and practice do not seem to have reached deeply into ambulatory care.
Based on preoperative discussions, a patient undergoing knee replacement expected to receive spinal anesthesia; however, general anesthesia was administered, and the records did not note or explain this change. The patient suffered an unusual complication.
A young woman with Takayasu's arteritis, a vascular condition that can cause BP differences in each arm, was mistakenly placed on a powerful intravenous vasopressor because of a spurious low BP reading. The medication could have led to serious complications.
A woman hospitalized for CHF (with no history of diabetes) is given several rounds of insulin and D50, after repeated blood tests show her glucose to be dangerously high, then dangerously low. Turns out, the blood samples were drawn incorrectly and the signouts were incomplete.
Housestaff evaluate and admit a severely ill patient with lupus, suspect a viral syndrome, and do not initiate antibiotics. Despite discovery of the correct diagnosis in the morning by the attending, the patient dies.
