Postoperative Complications Clinical Trial
Official title:
Alert Frequency, Nurse, and Patient Satisfaction With a Continuous Wireless Vital Sign Monitoring Software Across Health Care Systems and Cultures
The goal of this prospective, international multi-centre pilot study is to assess the functionality and user experience of a new vital sign monitoring system in 20 patients and 20 nurses in the general ward at each centre. The patients will be monitored with a wireless, continuous vital sign monitoring systems and answer a questionnaire afterwards. They will in addition have vital signs monitored as per standard practice. The nurses will answer a questionnaire after having had the responsibility for a monitored patient for a full shift. The main aims are: To determine the frequency of alerts activated in the app in relation to the alerts that should be activated based on measured data, to explore current practices of in-hospital monitoring by semi-structured interviews to map differences across systems and to test nurse and patient satisfaction.

Primary | Frequency of alerts activated in the app in relation to the alerts that should be activated based on measured data | during monitoring period, on average 3 months | ||
Secondary | Technical feasibility | will be assessed as data capture of vital signs as percentage of data from each of the vital sign sensors of the total monitoring period. | during monitoring period, on average 3 months | |
Secondary | Alert relay to smartphones | will be assessed by comparing % of alerts received compared to alerts generated by the WARD24/7 App. | during monitoring period, on average 3 months | |
Secondary | Response to alerts | will be assessed using the response buttons as % of nurses pressing attend, snooze, or refer to colleague on the WARD24/7 App. | during monitoring period, on average 3 months | |
Secondary | Patients experiences from being monitored with wCSVM. | will be assessed by a questionnaire named "Patient experience with wireless vital sign monitorering" consisting of 8 items. Each item can be answered with: strongly agree, agree, neither agree nor disagree, disagree, and strongly disagree. | during monitoring period, on average 3 months | |
Secondary | Relevance of alarms | by using feedback from the nurses given in the app, % of relevant alerts | during monitoring period, on average 3 months | |
Secondary | Frequency of delivered alarms on oxygen saturation (SpO2) pr patient pr day | during monitoring period, on average 3 months | ||
Secondary | Frequency of delivered alarms on respiration rate (RR) pr patient pr day | during monitoring period, on average 3 months | ||
Secondary | Frequency of delivered alarms on heart rate (HR) pr patient pr day | during monitoring period, on average 3 months | ||
Secondary | Frequency of delivered alarms on blod pressure (BP) pr patient pr day | during monitoring period, on average 3 months | ||
Secondary | Overall score of user satisfaction from use of WARD24/7 app | assessed by the mHealth App Usability Questionnaire (MAUQ) consisting of 18 items. In this questionnaire, 1 - strongly disagree, 2 - disagree, 3 - somewhat disagree, 4 - neither agree nor disagree, 5 - somewhat agree, 6 - agree, 7 - strongly agree.To determine the usability of an app, calculate the total and determine the average of the responses to all statements. The higher the overall average, the higher the usability of the app. | during monitoring period, on average 3 months | |
Secondary | Subscale MAUQ scores | assessed by the mHealth App Usability Questionnaire (MAUQ) consisting of 18 items. In this questionnaire, 1 - strongly disagree, 2 - disagree, 3 - somewhat disagree, 4 - neither agree nor disagree, 5 - somewhat agree, 6 - agree, 7 - strongly agree.To determine the usability of an app, calculate the total and determine the average of the responses to all statements. The higher the overall average, the higher the usability of the app.
Ease of use and satisfaction (5 items, MAUQ_E), system information arrangement (7 items, MAUQ_I), and usefulness (6 items, MAUQ_U). |
during monitoring period, on average 3 months | |
Secondary | Monitoring practices prior to the wCVSM | assessed by a semi structured interview guide including information on type of monitoring (manual/intermittent, type of vital signs collected, frequency of measurements, escalation protocols etc.). | Baseline, on average 3 months |
