What is often referred to as the fifth vital sign?

Pain is commonly referred to as the fifth vital sign because it is an essential indicator of a patient's overall health and well-being, alongside the traditional four vital signs: temperature, pulse, respiration, and blood pressure. Recognizing pain as a vital sign emphasizes the importance of assessing and managing pain effectively in a healthcare setting. This concept arose from the understanding that pain can significantly affect a person's quality of life and can be indicative of underlying health issues or complications. By treating pain assessment as essential as monitoring physiological signs, healthcare providers are encouraged to adopt a more holistic approach in patient care, ensuring that patient comfort and pain management are prioritized.
