The Lampard Inquiry has heard from experts who say there is not enough proof that a monitoring technology used in mental health wards is effective. The technology, called Oxevision, uses cameras and sensors to track patients. Experts told the inquiry that the evidence is lacking for the system's ability to improve safety or outcomes. The inquiry is examining the use of such monitoring tools in mental health care. It is part of a wider investigation into patient deaths and care standards. The experts' comments suggest that hospitals may be adopting the technology without strong research to back it up. The Lampard Inquiry continues to hear evidence from various witnesses. The findings could affect how monitoring technologies are used in the future.
