The NHS is turning to technology to address productivity and workforce challenges, especially in mental health services. Innovative technologies like MindTech are being developed to enhance mental health care. However, the introduction of controversial technologies like body worn cameras and surveillance cameras in inpatient mental health settings has raised concerns.
One such technology, the ‘vision-based patient monitoring system’ (VBPMS) known as Oxevision, utilizes infrared-sensitive cameras in patients’ bedrooms to monitor vital signs without disrupting their sleep. A recent study evaluated the effectiveness of this technology in reducing self-harm incidents in mental health wards.
The study analyzed data from five quasi-experimental studies involving 12 intervention and 7 control wards across five NHS mental health trusts. The VBPMS intervention utilizes a secure unit in patients’ bedrooms with infrared-sensitive cameras that measure pulse, breathing rates, and provide real-time location-based alerts. The results showed a statistically significant reduction in self-harm incidents by 39% when data from Trusts A-D were combined.
However, the study has limitations, including heterogeneity in data from different wards and NHS Trusts, and concerns about study design transparency. The lack of clarity on control wards, potential selection bias, and the involvement of researchers employed by the company that sells the monitoring systems raise ethical and conflict of interest issues.
The study’s approach to analysis and exclusion of outliers without detailed explanation also pose challenges. It’s essential to conduct real-world evaluations with intention-to-treat analysis and ensure transparency in study design and funding sources. Further research is needed to assess the broader impacts of such technologies on patients and their care.
