What is the EarlySense System?

The EarlySense Contact-Free Monitoring System helps facilitate timely interventions for patients in non-ICU settings by adding a layer of care with continuous monitoring, drawing attention to those who may show early signs of deterioration and may require clinical intervention.

By utilizing contact-free sensor technology (no patient leads required), the EarlySense System continuously monitors a patient’s Heart Rate, Respiratory Rate and Motion to assist clinicians in:

  • Early Detection of Patient Deterioration and Avoiding Failure to Rescue
  • Fall Risk Reductions
  • Pressure Ulcers Prevention

EarlySense’s real time delivery of actionable data, together with patient management tools, empowers the medical staff to identify potentially critical situations. It provides proactive personalized patient care and allows the medical staff to reduce adverse events.


How does the EarlySense System work if there is no direct contact with the patient?

Utilizing piezoelectric technology integrated into a membrane plate, the sensor detects mechanical vibrations from the patient. The sensor collects the signal, and the system algorithms analyze it to extract the following:

  • Heart Rate – by identification of the signal generated by the cardio ballistic effect of the heart.
  • Respiration Rate – by identification of the signal generated by the chest movement and respiratory system pattern changes.
  • Movement – by identification of the signal generated by large body movement, such as changes in posture.
  • Bed Exit – by identification of the signal generated by body movement when attempting to, or actually leaving the bed.


What Differentiates the EarlySense System from Other Monitoring Systems?

  • Continuous monitoring including patient’s HR and RR trends and trend analysis to potentially allow early detection of patient deterioration
  • The EarlySense Contact-Free Sensor is placed under the mattress, there are no leads attached to the patient. There is no need for patient compliance.
  • The EarlySense System was designed for the general care environment with the challenging nurse to patient ratio and the alarm fatigue in mind.
  • Immediate access to accurate patient data. All monitored information is available on the Bedside Unit, Central Station, Hallway Displays and on Hand-Held Devices. Nurses can follow-up and check on their patients wherever they are.
  • Default Alarm Thresholds are set based on the Unit Manager’s preference (unit’s clinical policy). Clinicians are able to change each parameter’s thresholds to better suit each individual patient.
  • Management tools: Management of response times, turn protocols, default thresholds, etc.


Do you have any hospital staff reports about the use of the EarlySense System?

A Hospital in CA, USA Reports:1

  • 89% of nurses reported that monitoring HR and RR and alerts for High / Low parameters helped identify deteriorating patients.
  • 92% of nurses reported that risk of fall was decreased.
  • 88% of nurses reported that patient turn reminders – set for patients who need it reduced pressure ulcers.
  • 93% of nurses reported the system to be very easy to use. 82% felt fully at ease using the system on their own after 2 weeks.


How is the staff notified of alerts?

The EarlySense System sends alerts to the Nurse’s Central Display Station (CDS) and simultaneously to pagers or staff’s mobile devices. Alerts can also be displayed (and heard if desired) on hallway screens.

The EarlySense System can integrate with a variety of mobile / convenient notification devices, such as the Vocera Badge, Spectralink and Cisco phones. Please consult with an EarlySense Representative when considering integration.


How often can nurses expect to see or hear EarlySense device alerts (alarms)?

The alarm frequency with the EarlySense System is 2.2 on average per nurse in a typical 12-hour shift when caring for 5 patients. This is based on the outcome from a study which was completed about EarlySense’s alarm frequency and patient outcomes. This is also consistent with what our user sites have reported. In comparison, devices that have been designed and intended for acute care environments can reach hundreds of alarms on a per-shift basis.


What are the potential clinical benefits when using the system?

In a recently published study in the American Journal of Medicine, researchers showed improvements in patient outcomes. The study included more than 7,600 patients. The published results showed decrease in Code Blue events by 86%, overall ICU days for patients coming from Med-Surg decreased by over 45% and the overall length of stay decreased by 9% .

These types of results have also been reported by other users of the EarlySense System and presented in several scientific conferences (e.g. AGS, 2013, AONE, 2013). Along with these formally published study results, there are dozens of actual patient case studies, which show that the early warning provided to caregivers by the EarlySense System, helped save patients from potential injury and clinical deterioration. 1

In addition, an economic return on investment model developed by researchers from Harvard University Medical School and published in the Journal of the Society of Critical Care Medicine, April 2014, shows that the implementation of the EarlySense monitoring system was associated with a highly positive return of investment with a breakeven point achieved within 6-9 months:


What is the accuracy of the EarlySense parameters?

HR Accuracy: +/- 10% or 5 BPM, whichever is greater (compared to EKG). RR Accuracy: +/- 10% or 2 Br/min, whichever is greater (respiratory belts and end -tidal Co2).


Is the EarlySense sensor Disposable?

The sensor is not a disposable item and only requires to be replaced once a year. The sensor is placed under the mattress with no direct contact with the patient.


What mattresses does EarlySense work with?

The EarlySense system has successfully monitored patients with many different types of passive and active mattresses. Prior to installation, on-site testing is performed on the different mattress types utilized by a facility to ensure proper performance of the system.


Can EarlySense integrate with EMR?

The EarlySense System integrates with hospital information systems and medical dashboards.

The interface and integration are done through a Gateway computer to the hospitals EMR network via HL7, XML, or Cerner iBus protocol. Additionally, the system is compatible with ADT and Alerting IT Systems. EarlySense is also Cerner Certified.


Which Clinical Environments is the EarlySense used in presently?

EarlySense is used commonly within med/surg, oncology, orthopedics, isolation, and post-partum departments, as well as in skilled nursing facilities, long-term acute care and rehabilitation centers.
