A common misconception on the ward is that ‘continuous monitoring’ automatically implies ICU‑level vigilance. In practice, the wearables used on a general ward produce trend data that are updated every few minutes, not second‑by‑second waveforms. Nurse‑to‑patient ratios are higher, patients are mobile, and data gaps can occur if a biosensor loses contact. Consequently, the response time does not often match that of a fully staffed ICU.
UMC Utrecht’s clinicians had to make this distinction explicit: the wearable technology is a safety net, not a replacement for truly ‘real-time’ 24/7 monitoring and staff-to-patient ratios of an ICU setting. Clear communication of these limits prevents unrealistic expectation which precipitate burnout.

Modern wireless biosensors generate millions of data points per patient per day. Ward nurses, already stretched thin, cannot manually review every number. Furthermore, UMC Utrecht’s teams have observed that existing biosensor technology often generates alerts that are not clinically actionable. This is because many commercial devices use threshold‑based alarms, which fire far more often than they signal a clinically actionable event. This can lead to alarm fatigue for nursing staff. Without intelligent filtering, clinicians are forced to triage noise.
Because AI‑driven predictive algorithms are not yet mature enough for bedside use, UMC Utrecht adopted a hybrid workflow to facilitate rapid rollout.
This system is designed to support staff workload and continuous patient observation, while preparing for future workflow enhancements as technology develops.
Technical solutions alone do not guarantee adoption. At UMC Utrecht, the biggest obstacle was changing entrenched habits. For decades, ward teams relied on intermittent manual vital sign checks. Introducing a constant stream of data, with a ‘virtual ward’ environment, required a cultural shift: clinicians had to trust a remote signal, learn to interpret trends, and incorporate this information into their patient management strategies.
Patience is vital during transformations of this nature. While implementation is a vital first step, adoption of wearable technologies and associated processes can take longer – but it should also be the clear long-term goal for clinicians and nurses alike.
For UMC Utrecht, patient-reported outcome measures (PROMs) are vital to study and collect in order to evaluate whether technology is associated with benefits in this transformation process, since these provide clear insights and metrics that allow the technology delivers holistic benefits for patients as well as staff.
For UMC Utrecht, a long-term goal is to explore replacing rule-based alarms with predictive AI that may anticipate deterioration before it manifests in vital-sign changes. The ‘hybrid’ workflow model is intended as a pragmatic bridge to that future, supporting current safety practices while the evidence base for AI continues to develop.
By treating wearable technology as an extension of the care team – rather than a replacement – the goal is that organizations can create hospital discharge planning pathways that are both data‑rich and human‑focused.
