COVID-19 risk perceptions, worries and preventive behaviors in patients with previous pulmonary embolism

Abstract

IntroductionThe presence of conditions, such as cardiovascular or chronic lung diseases, was reported to be associated with more severe cases of COVID-19. It is, however, so far unclear how patients with a history of pulmonary embolism (PE) perceive their individual COVID-19 risk. Moreover, their worries and preventive behaviors and their associations with risk perception are unknown. Materials and methodsA postal survey was conducted in April 2020, including participants with previous PE from the German “Lungenembolie Augsburg” (LEA) cohort study. The questionnaire contained items on COVID-19 knowledge, risk perception (infection likelihood, susceptibility, dangerousness), information sources and satisfaction with information, individual assignment to a high risk group due to pre-existing conditions, worries, infection likelihood, and implementation of preventive behaviors. ResultsFrom the 185 respondents, 71.7% assigned themselves to a high risk group in terms of developing a severe case of COVID-19. The likelihood of being infected was rated as verylow/low by 82.3% and the susceptability by 37.8%. A considerable percentage of patients expected a very high/high infection risk in a hospital (48.3%) or at a doctor's practice (37.9%). Major sources of information were the patients' general practitioners (48.9%) and the internet (31.5%). Assignment to a high risk group (β = 1.04) and uncertainty in terms of assignment (β = 1.26) were significantly (p = 0.01) associated with a higher level of health-related worries. ConclusionsMost patients with previous PE feel that they belong to a high risk group in terms of severe illness from COVID-19. Support in coping with their individual COVID-19 risk is warranted.
