Failure to maintain staff observation of the Oxevision monitor during WiFi disruption
Wider context from the report
“1. Mental Health Trust Staff on Longfield Ward: a. Elise was neurodiverse and staff were not trained in Autism b. were inexperienced. The majority were new bank and agency staff with limited experience working with detained children, and this matter had been raised by the Care Quality Commission about other Trust services in January 2021. c. Did not have sufficient staffing to conduct observations required by the doctors for patients on the ward. This was known to the mental health Trust management and had been raised by the ward manager. During the time of Elise’s admission, the staff member allocated for observations was required to conduct approximately 66 observations within an hour. This was not logistically possible. Management knew that staffing allocation on Longview Ward was not sufficient to conduct the required levels of observations to keep the patients safe. Evidence was heard during the inquest that there are still observations that are not being conducted either as required or at all within the Trust and remains an ongoing concern. Datix reporting incidents are not always raised. d. The mental health Trust implemented a system called Oxevision with a Project Board to assist with the planning and roll out of the new system. There were difficulties with the roll out on St.Aubyns ward who were part of the pilot, due to WiFi coverage and the Oxevision system not operating correctly. e. The clinical management at the Trust Project Board meeting overseeing the roll out for Oxevision, required that ward staff implement a procedure where the Oxevision fixed monitor in the ward office be observed by a member of staff whilst the WiFi problem was resolved. This did not happen on Longview Ward. f. The Trust Project Group had reports that WiFi was not working and any issues were required to be reported as incident reports on Datix forms but these were not being completed. The Trust Project Board did not question why they were not receiving the Datix forms with the known issues. There was no oversight of what was required to ensure that the roll-out was operating appropriately and/or what the Project Board expected in the interim whilst the WiFi difficulties were being investigated. g. Not all the Trust staff on the ward were trained to use the Oxevision System. h. There was disputed evidence about the volume on the fixed terminal for Oxevision in the office about whether the alert volume could be turned down or ‘muted’. It was established that there was no incident unrelated to Elise’s death where a doctor did turn this volume down on the ward. ”

Failure to ensure in-person checks after bathroom alerts
Wider context from the report
“(4) Bathroom alerts – Evidence was heard that an Oxevision alert is triggered if a person is in the bathroom for more than 3 minutes and staff are required to complete an in-person check. Morgan-Rose was left in the bathroom unobserved for approximately 50 minutes. It was not clear from the evidence how the Trust proposes to ensure compliance in respect of this duty. ”

Wider context from the report
“(6) Staff entries in patient observations sheets should have given rise to a concern that some staff may have been using Oxevision not just as an adjunct to face-to-face observations, but instead of them. This remains a concern. ”
