Boerlage AA, et al. - Experts assessed whether or not the Rotterdam Elderly Pain Observation Scale (REPOS) is also reliable and valid for pain assessment in the hospital setting. In this prospective multicenter observational study, they observed surgical patients perioperatively at bedside and internal medicine patients were filmed during a possible painful moment and in rest. As per data, in hospital patients who cannot self-report pain the REPOS is reliable and valid for the assessment of postoperative and chronic pain. They noted an association between the REPOS and NRSobs of 0.67 and the REPOS and NRSproxy of 0.73; as revealed in linear mixed modeling.
