The Impact of Indoor Environmental Quality on Symptoms in Patients With Chronic Obstructive Pulmonary Disease
Sponsor: Ziekenhuis Oost-Limburg
Summary
This prospective, monocenter pilot study will investigate the relationship between indoor environmental quality (including air quality, lighting, noise, and thermal conditions), wearable-derived health insights, and patient-reported symptoms in patients recovering at home after hospitalization for an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Participants will undergo continuous monitoring of indoor environmental conditions and health parameters using a Garmin Venu 4 smartwatch, together with validated questionnaires assessing COPD symptoms, sleep quality, and daytime sleepiness during one month. The study will assess the feasibility and potential added value of high-resolution home monitoring and explore whether environmental and wearable-derived measures are associated with symptom burden and early signs of clinical deterioration following hospital discharge. The investigators hypothesize that continuous in-home monitoring of indoor environmental quality is feasible and provides clinically relevant insights into symptom burden in recently hospitalized COPD patients. The primary objective is to determine the correlation between indoor environmental quality (IEQ) variables and symptom burden in COPD patients following hospitalization for AECOPD.

Interventions
Wearable mobile device
Patients admitted due to an acute COPD exacerbation will be asked to wear the wearable mobile device for a period of one month after hospital discharge. An app linked to the device will be installed on their phone, and used to send health insights to the investigators.
Indoor environmental quality sensor
When the participants are discharged home, an indoor environmental quality sensor will be installed in the patient's home. One sensor will be installed in the bedroom, one in the living room or kitchen (wherever the patient spends the most time). Data from these sensors will be sent to the hub (placed central between the sensors) and thereafter, to the investigators. The sensors measure particulate matter concentrations, CO2 concentrations, VOC concentrations, temperature, relative humidity, ambient light, and ambient noise.
CAT Questionnaire
A COPD Assessment Test questionnaire will be taken during the hospitalization (start of the study), and weekly after discharge.
PSQI Questionnaire
A Pittsburgh Sleep Quality Index questionnaire will be taken 4 weeks after hospital discharge (end of the study).
KSS Questionnaire
A Karolinska Sleepiness Scale questionnaire will be taken daily after discharge.
SQS Questionnaire
A sleep quality scale questionnaire will be taken daily after discharge.
PROMs Questionnaire
A PROMs questionnaire will be taken daily after discharge.
eHLQ Questionnaire
An eHealth literacy questionnaire will be taken during the hospitalization (start of the study), and 4 weeks after hospital discharge (end of the study).
Housing Questionnaire
A housing questionnaire will be taken during the hospitalization (start of the study).
