Brief Summary

The study has 7 research questions regarding the use of the air quality sensor in residential care home for the elderly: Primary study questions:

1. 1.Can the real-time monitoring of air quality and the subsequent activities to improve air quality and long-term measures reduce respiratory symptoms?
2. 2.Can the real-time monitoring of air quality and the subsequent activities to improve air quality and long-term measures reduce pulse rate, systolic blood pressure and diastolic blood pressure?
3. 3.What are the activities to improve air quality and long-term measures that aim to improve air quality, including the rationales for change and non-change of the measures?
4. 4.What are the changes in air quality indexes recorded by the air quality sensor?
5. 5.How many days do the residents feel sick and stay in hospitals?
6. 6.What are the perceived benefits and feasibility of the air quality sensor?

Outcome Measures

Primary Outcomes (1)

• Change from Baseline respiratory symptoms every two weeks until week 14

  Change of four respiratory symptoms of participants, including coughing, having sputum, having shortness of breath and having runny nose, will be observed and recorded by the care staff every two weeks. Care staff will complete four items on a 5-point Likert scale (i.e. 1 indicating no symptoms and 5 indicating serve symptoms). The minimum and maximum values of the scale is 5 and 25 respectively, with higher score indicating more severe respiratory symptoms.

  From the start of 2-week pre-test to the end of 12-week trial period

Secondary Outcomes (13)

• Change from Baseline pulse rate every week until week 14

  From the start of 2-week pre-test to the end of 12-week trial period

• Change from Baseline blood pressure every week until week 14

  From the start of 2-week pre-test to the end of 12-week trial period

• Qualitative measures: Change of air quality improvement measures every two weeks until week 14

  From the end of 2-week pre-test to the end of 12-week trial period

• The changes in temperature until week 14

  From the start of 2-week pre-test to the end of 12-week trial period

• The changes in humidity until week 14

  From the start of 2-week pre-test to the end of 12-week trial period

Study Arms (1)

Air quality sensors

EXPERIMENTAL

The experimental group will use the air quality sensors during 2 weeks pre-test and 12 weeks trial period.

Device: Air quality sensors

Interventions

Air quality sensors DEVICE

The air quality sensors detect air quality, including temperature, humidity, carbon dioxide, respirable suspended particulates (PM10 or PM2.5), total volatile organic compounds (TVOC) and formaldehyde (HCHO), which may influence health of residences. The managers of the service unit will decide the changes of activities to improve air quality and long-term measures based on the detected air quality indexes. The care staff will follow these decisions.

Model Details: The air quality sensors will install at the designated places and only serve to provide air quality indexes for the study site to improve air quality. The sensors will detect air quality at 2 weeks during the pre-test period and the alarm threshold will be set base on the 2-week data. During the 12 weeks trial period, based on the analysis on past 2-week air quality indexes, the managers of service unit will decide the changes of activities to improve air quality and long-term measures. The respiratory symptoms, blood pressure, pulse rate of participants will be collected during the pre-test and trial period.
