The Perceived Efficiency and Acceptability of Remote Real-time Health Monitoring System in Elderly Residential Setting and Community Isolation Facility

Study design

This is a single-group 4-week trial of using the remote health monitoring system. All care staff who manage the system will complete a very brief survey (1-minute) after each work shift for 2 weeks. Detection of abnormal vital signs will be recorded by the system. Hospital admission and further medical assistance due to the adoption of the system will be documented by the care team. The care staff will be interviewed about their perceived benefits and acceptability of the system.

Subjects

Care staff in Haven of Hope Woo Ping Care \& Attention Home and Haven of Hope Nursing Home who are responsible to set up and operate real-time remote health monitoring system will be recruited. They also need to be able to read and understand Chinese.

Procedures

Implementation

The remote monitoring system will record the temperature, pulse and oxygen saturation (SpO2) of the residents wearing the equipment every minute. When the staff find abnormal vital signs, they will provide further medical assistance. After every shift during the trial period for 2 weeks, they will fill in a 1-minute survey.

Data collection

The remote monitoring system will remotely and real-time record the temperature, pulse and SpO2 of the residents wearing the sensor. The sensor is like a ring that wraps a finger. When the staff are notified of any abnormal vital signs by the system via screen display and notification sound, they will deliver further medical assistance. Hospital admission and further medical assistance due to the adoption of the system will be documented by the care team under pre-existing practice. After every shift during the trial period for 2 weeks, the staff will fill in a 1-minute survey about their operation and perceived efficiency of the system, such as facilitating more frequent monitoring of particular residents' vital signs, the provision of further medical assistance, perceived time saving in monitoring vital signs, and acceptability of the system. They could record their experience of using the system in a messaging mobile phone app in audio format. If they fill in the survey for fewer than 10 times during the 2 weeks, they would be invited to continue to fill in the survey after work shift after the 2 weeks until they fill in it for at least 10 times. Meanwhile, as a staff may complete more than 1 shift per day, they would not be invited to fill in the survey after having completed it for 12 items. All data collected that is related to residents is not identifiable.

There are two parts of the qualitative sub-study. When the system is set up, the unit in-charge and care staff responsible to set up the system from each participating unit will be interviewed by research assistant(s). Themes of qualitative questions include: (1) barriers and difficulties in the set-up of the system; and (2) the concerns in choosing wireless or cable connection for the monitoring device. Meanwhile, when the main trial ends, a total of 8-10 care staff from all participating units responsible to operate the system will be interviewed about their perceived benefits and acceptability of the system. Themes of qualitative questions include: (1) Acceptance of using the remote health monitoring system (including ease of operation, care staff's confidence and convenience in using the system); (2) Benefits of using the remote health monitoring system (including usefulness of the innovation, impacts on quality of care); (3) Concerns in using the remote health monitoring system (including if any residents stop using the sensor and the reason behind); and (4) Overall perception of using the remote health monitoring system. For both parts of the qualitative sub-study, an interview guide with open-ended and iterative questions will be used to probe for more experiences from the interviewees. Each interview will be conducted by a trained research assistant and will last about 15 - 30 minutes.

Blinding

Blinding is not applicable in this single group study.

Sample size determination

The sample size is estimated by the number and availability of the staff in the participating units. It is estimated that a total of 10-12 staff will be recruited.

Data analyses

The proportion of all the responses in the staff survey will be calculated. The number of abnormal vital signs, hospital admission and further medical assistance due to the adoption of the system will be counted.

The qualitative interview content will be transcribed verbatim in Chinese for further analysis. The qualitative interview transcripts will be analyzed using framework analysis to construct a coherent and logical structure from the classification of many opinions and perceptions of the system. The results will then be discussed and consolidated in the panel meetings with the co-authors.
