Clinical Classification and Interventions for Post–COVID-19 Condition: A Scoping Review

Key Messages

• Most of the identified published research focused on characteristics or outcomes of having post–COVID-19 condition (e.g., symptoms, quality of life) or predictors for developing post–COVID-19 condition. There were fewer studies related to preventing post–COVID-19 condition or treatments. Ongoing studies, according to published protocols, will investigate interventions to prevent or treat this condition.
• Notable evidence gaps included post–COVID-19 condition as it relates to people living in rural or remote areas, children and adolescents, and vaccination status. There were few economic studies, qualitative studies, and studies assessing health systems issues.
• Most identified guidelines regarding the diagnosis, treatment, and management of post–COVID-19 condition, including all Canadian guidelines, provided limited guidance specific to patients meeting the WHO definition. These guidelines will need continual updates as new evidence emerges.
