[Position document of the spanish association of paediatrics group for the study of paediatric pain on the recording of pain as fifth vital sign].

The Spanish Group for Children's Pain Study was created in 2017 in an aim to prevent, remove or reduce pain in neonates, infants, children, and adolescents. Along with a diagnosis of pain, a paediatric patient may suffer from acute or chronic pain, neuropathic, nociceptive, or mixed pain, as well as pain from procedures, and post-surgical pain. Pain suffering is too often ignored and not diagnosed.
