7 Acute and older adult results are standardised for a 16-bed ward with 90% occupancy; PICU results are standardised for a 12-bed ward with 90% occupancy.
Cost savings are associated with staff working beyond planned staffing levels. Time savings are for staff working within planned staffing levels.
Acute and PICU data comes from seven wards; older adult data comes from five wards.
Data comes from nine wards (three PICU, three acute, three older adult).
Data comes from five wards (one PICU, two acute, two older adult).

Reductions in falls, transfers to A&E and 1:1 observations

Reduction in bedroom falls at night14

Reduction in transfers to A&E
(p = 0.02)
13 Two intervention wards (12-bed male dementia and 12-bed female dementia). Oxevision was installed in 6 bedrooms per ward. i.e. half of all bedrooms across the two wards.
14195 falls were recorded in the pre go-live period. 101 falls were were recorded in the post go-live period.
Accumulated projected falls pre go-live were calculated using the monthly average bedroom falls at night during this period.

Using digitally assisted nursing observations to keep patients safe and improve patient and staff experience

4-month qualitative study in acute mental health care16

All patients admitted to an acute inpatient mental health unit must have nursing observations carried out at night either hourly or every 15 minutes, to ascertain that they are safe and breathing. However, while this practice ensures patient safety, it can also disturb patients’ sleep, which in turn can impact negatively on their recovery.

Objective This article describes the process of introducing artificial intelligence (’digitally assisted nursing observations’) in an acute mental health inpatient ward, to enable staff to carry out the hourly and the 15 minutes observations, minimising disruption of patients’ sleep while maintaining their safety.

The preliminary data obtained indicate that the digitally assisted nursing observations agreed with the observations without sensors when both were carried out in parallel and that over an estimated 755 patient nights, the new system has not been associated with any untoward incidents. Preliminary qualitative data suggest that the new technology improves patients’ and staff’s experience at night.

Discussion This project suggests that the digitally assisted nursing observations could maintain patients’ safety while potentially improving patients’ and staff’s experience in an acute psychiatric ward. The limitations of this study, namely, its narrative character and the fact that patients were not randomised to the new technology, suggest taking the reported findings as qualitative and preliminary.

Clinical implications These results suggest that the care provided at night in acute inpatient psychiatric units could be substantially improved with this technology. This warrants a more thorough and stringent evaluation.
