RETRACTED: Reduced self-harm on acute mental health wards following the implementation of a vision-based patient monitoring system: Evidence from five NHS trusts.

WHAT IS KNOWN ON THE SUBJECT?: Inpatient mental health settings pose unique challenges for patient safety, in part because psychiatric disorders are well-known risk factors for self-harm and suicide. Ward staff follow protocols to try and keep patients safe including carrying out in-person safety checks, usually every 15 min, but patients unfortunately still find opportunities to harm themselves. A vision-based patient monitoring system (VBPMS) is a contact-free technology that can help mental health nurses to monitor patients in hospital more effectively. For example, the tool alerts staff to situations where a patient might need assistance, like when they spend a long period of time in their ensuite bathroom. Research has shown that the VBPMS can support staff to prevent safety incidents from occurring and a recent study found a decrease in self-harm after the tool was implemented at one NHS mental health trust. WHAT DOES THE PAPER ADD TO EXISTING KNOWLEDGE?: This paper presents data from five NHS mental health trusts and suggests that the VBPMS can consistently help staff to prevent self-harm on acute mental health wards. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Managing self-harm behaviours is a challenge for mental health nursing staff. Standard safety protocols are not effective enough - staff need new ways to monitor patients. In general hospitals, technology is used every day to support care. This research shows that the VBPMS can be used to improve patient safety in mental health hospitals. ABSTRACT: Introduction Self-harm is sadly relatively common in mental health inpatient settings, and the effectiveness and appropriateness of strategies used to prevent it have long been disputed. The use of vision-based patient monitoring systems (VBPMS) has been shown to improve various safety outcomes. Their potential to support staff in preventing inpatient self-harm warrants further exploration. Aim This research investigated whether implementing a VBPMS-as an adjunct to existing clinical practice-within acute inpatient services at five NHS England mental health trusts led to reductions in self-harm. Method Five quasi-experimental studies assessed the number of bedroom self-harm incidents, across 12 adult wards, before and 5-12 months after a VBPMS was deployed. Percentage changes were calculated. Four studies used control groups and were included in a fixed-effect meta-analysis. Results In the meta-analysis, a significant inverse-weighted average relative risk percentage change of -38.9% was recorded. For the study with no control groups, reductions in self-harm were seen across all wards (range: -9.1% to -29.8%). Discussion This research demonstrates that VBPMS can support clinicians to create safer ward environments by preventing incidents of self-harm from occurring. Implications for Practice The results provide preliminary support for wider rollout of the technology on acute mental health wards.

Economic impact of a vision-based patient monitoring system across five NHS mental health trusts.

A vision-based patient monitoring system (VBPMS), Oxevision, has been introduced in approximately half of National Health Service (NHS) mental health trusts in England. A VBPMS is an assistive tool that supports patient safety by enabling non-contact physiological and physical monitoring. The system aims to help staff deliver safer, higher-quality and more efficient care. This paper summarises the potential health economic impact of using a VBPMS to support clinical practice in two inpatient settings: acute mental health and older adult mental health services. The economic model used a cost calculator approach to evaluate the potential impact of introducing a VBPMS into clinical practice, compared with clinical practice without a VBPMS. The analysis captured the cost differences in night-time observations, one-to-one continuous observations, self-harm incidents, and bedroom falls at night, including those resulting in A&E visits and emergency service callouts. The analysis is based on before and after studies conducted at five mental health NHS trusts, including acute mental health and older adult mental health services. Our findings indicate that the use of a VBPMS results in more efficient night-time observations and reductions in one-to-one observations, self-harm incidents, bedroom falls at night, and A&E visits and emergency service callouts from night-time falls. Substantial staff time in acute mental health and older adult mental health services is spent performing night-time observations, one-to-one observations, and managing incidents. The use of a VBPMS could lead to cost savings and a positive return on investment for NHS mental health trusts. The results do not incorporate all of the potential benefits associated with the use of a VBPMS, such as reductions in medication and length of hospital stay, plus the potential to avoid adverse events which would otherwise have a detrimental impact on a patient's quality of life.

Implementing and evaluating patient-focused safety technology on adult acute mental health wards.

Mental health wards can feel unsafe. We know that patients and staff have different ideas about what makes a hospital ward safe or unsafe. Patients are often the first to know when the atmosphere on a ward becomes tense, but often, no one asks them for their views. Patients and staff are experts and should be included in discussions about how to make wards safer. We got together with some service users and staff, and made an app that helps patients to tell staff when they are not feeling safe on a mental health ward. We tried it out on six wards and we asked patients and staff what they thought. The app was easy to use and most people liked the look of it. Patients said staff did not talk with them enough and so they liked using the app. However, some staff said they could tell how patients were feeling without an app and so they did not need it. Ward managers told us that staff were often very busy and did not always have time to use the app. This app could help staff know straightaway when patients do not feel safe on the ward, so that they can act quickly to calm things down. To make the most of the app, staff need to get used to it and bring it into ward routines. INTRODUCTION: Safety improvement on mental health wards is of international concern. It should incorporate patient perspectives. Implementation and evaluation of 'WardSonar', a digital safety-monitoring tool for adult acute mental health wards, developed with stakeholders to communicate patients' real-time safety perceptions to staff. Six acute adult mental health wards in England implemented the tool in 2022. Evaluation over 10 weeks involved qualitative interviews (34 patients, 33 staff), 39 focused ethnographic observations, and analysis of pen portraits. Implementation and evaluation of the WardSonar tool was feasible despite challenging conditions. Most patients valued the opportunity to communicate their immediate safety concerns, stating that staff had a poor understanding of them. Some staff said the WardSonar tool could help enhanced ward safety but recognised a need to incorporate its use into daily routines. Others said they did not need the tool to understand patients' safety concerns. Foreseeable challenges, including staff ambivalence and practical issues, appeared intensified by the post-COVID-19 context. The WardSonar tool could improve ward safety, especially from patients' perspectives. Future implementation could support staff to use the real-time data to inform proactive safety interventions.
