Abstract
Aim: The aim of this study is to analyze COPD exacerbation rates and the
effect of patients’ behavioral changes on the exacerbations during the
pandemic. Materials and Methods: Conducted in a reference hospital for
chest diseases, patients hospitalized with an exacerbation of COPD
between 11.03.2019 and 11.03.2020 were designated. Patients’ COPD
exacerbations requiring emergency department (ED) visits and/or
hospitalization were compared between 11.03.2019 - 25.12.2019
(pre-pandemic period) and 11.03.2020 - 25.12.2020 (pandemic period).
Each patient was surveyed with 25 questions using telemedicine. Results:
Of all the 256 patients, 203 (79%) were male and the mean age was
66±10. Compared to the previous year, ED visits and hospitalizations in
our hospital were significantly lower and less frequent
(p<0.0001, for both). Smoking habit decreased in 9%, and 60%
had hardly spent time in outdoors (e.g., parks and gardens). Only three
patients reported to spend time indoors (e.g., cafes and restaurants).
Household mask-use rate while contacting the patient was 50%. As a COPD
patient, 33% expressed themselves as “feeling better”. Overall, 92
(36%) patients were recorded not to have any exacerbation, 34 (13%) to
have no attacks of worsening that they were managed at home. Novel
exacerbation risk was found to independently correlate with younger age
(OR: 0.944,CI:0.904-0.986, p=0.010) and having more frequent episodes of
exacerbation in the pre-pandemic period (OR:1.2,CI:1.025-1.405,
p=0.023). Conclusion: COPD patients specifically benefited from
confinements, restrictions and lifestyle changes. Further studies are
needed to better identify the most critical factors leading to these
positive outcomes. A permanent patient management guideline for COPD
patients could be formulated where the weight of lifestyle factors is
elevated.
