Diagnostic errors occur when a healthcare professional fails to identify a medical condition accurately. This can happen due to misinterpretation of symptoms, inadequate testing, or overlooking critical information. Such errors can lead to incorrect treatments, delayed care, and potentially worsen a patient's health. These mistakes can stem from various factors, including cognitive biases, communication breakdowns, and system-related issues within healthcare settings. Addressing diagnostic errors is essential for improving patient safety and ensuring that individuals receive the appropriate care for their conditions. Continuous education and better diagnostic tools can help reduce these errors.
