To avoid a surge of demand on the healthcare system due to the COVID-19 pandemic, we must reduce transmission to individuals with chronic conditions who are at risk of severe illness with COVID-19. We aimed at understanding the perceptions, context and attitudes of individuals with chronic conditions during the COVID-19 pandemic to clarify their potential risk of infection.
A cross-sectional survey was nested in ComPaRe, an e-cohort of adults with chronic conditions, in France. It assessed participants' perception of their risk of severe illness with COVID-19; their context (i.e., work, household, contacts with external people); and their attitudes in situations involving frequent or occasional contacts with symptomatic or asymptomatic people. Data were collected from March 23 to April 2, 2020, during the lockdown in France. Analyses were weighted to represent the demographic characteristics of French patients with chronic conditions. The subgroup of participants at high risk according to the recommendations of the French High Council for Public Health was examined.
Among the 7169 recruited participants, 63% patients felt at risk because of severe illness. About one quarter (23.7%) were at risk of infection because they worked outside home, had a household member working outside home or had regular visits from external contacts. Less than 20% participants refused contact with symptomatic people and <20% used masks when in contact with asymptomatic people. Among patients considered at high risk according to the recommendations of the French High Council for Public Health, 20% did not feel at risk, which led to incautious attitudes.
Individuals with chronic conditions have distorted perceptions of their risk of severe illness with COVID-19. In addition, they are exposed to COVID-19 due to their context or attitudes.
为避免因 COVID-19 大流行导致医疗系统需求激增，我们必须减少向患有慢性病且有 COVID-19 重症风险的个体传播。我们旨在了解 COVID-19 大流行期间慢性病患者的认知、背景和态度，以明确他们的感染潜在风险。
本研究是在 ComPaRe 中嵌套的一项横断面调查，ComPaRe 是法国患有慢性病的成年人电子队列。该研究评估了参与者对 COVID-19 重症风险的认知；他们的背景（即工作、家庭、与外部人员的接触）；以及在与有症状或无症状人员频繁或偶尔接触的情况下的态度。数据收集于 2020 年 3 月 23 日至 4 月 2 日，当时法国正处于封锁期间。分析结果进行了加权处理，以代表法国慢性病患者的人口统计学特征。还检查了根据法国高级公共卫生理事会建议处于高风险的参与者亚组。
在招募的 7169 名参与者中，63%的患者因重病而感到有风险。约四分之一（23.7%）因在家庭以外工作、家庭中有在家庭以外工作的成员或有定期外部接触者而有感染风险。不到 20%的参与者拒绝与有症状的人接触，不到 20%的人在与无症状的人接触时使用口罩。根据法国高级公共卫生理事会的建议被认为处于高风险的患者中，有 20%的人不认为自己有风险，这导致了他们不慎的态度。
患有慢性病的患者对 COVID-19 重症风险的认知存在偏差。此外，他们由于自身背景或态度而面临 COVID-19 的风险。
