Synthesis of Long COVID Symptoms: An Evidence-Based Standardized Mapping Study With the Omaha System

Abstract

Background:In COVID-19 survivors, symptom burden is a significant and multifaceted personal and societal challenge. The Omaha system is a standardized terminology used by researchers and clinicians for documentation and analysis of meaningful data for whole-person health. Given the urgent need for a standardized symptom checklist specific to the long COVID population, the purpose of the present study was to identify long COVID symptoms from the published literature (native symptoms) and map those to the Omaha system signs/symptoms terms.Methods:The long COVID symptoms identified from 13 literatures were mapped to the Omaha system signs/symptoms, using an expert consensus approach. The criteria for mapping were that the long COVID signs/symptoms had to contain either a one-to-one match (exact meaning of the native terms and the signs/symptoms) or a partial match (similar but not exact meaning).Results:The synthesis of the 217 native symptoms of long COVID and mapping analysis to the Omaha problems and signs/symptoms level resulted in a combined, deduplicated, and standardized list of 74 signs/symptoms for 23 problems. Of these, 72 (97.3%) of native signs/symptoms were a full match at the problem level, and 67 (90.5%) of native signs/symptoms were a full or partial match at the sign/symptoms level.Conclusions:The present study is the first step in identifying a standardized evidence-based symptom checklist for long COVID patients. This checklist may be used in practice and research for assessment, tracking, and intervention planning as well as longitudinal analysis of symptom resolution and intervention effectiveness.

Fatigue syndrome after COVID-19 infection: results of personal observations

“…В изученной популяции ожирением страдали 42% при ИМТ: M ± SD (кг/м 2 ) = 28 ± 5 (27)(28)(29). Из них ожирение: ■ 1-й степени -30%, ■ 2-й степени -8%, ■ 3-й степени -2%.…”

“…В литературе описано более 200 симптомов, выявляемых после перенесенной новой коронавирусной инфекции [28], при этом усталость может сочетаться с дыхательными расстройствами (abnormal breathing) [29]. Наши результаты так же демонстрируют связь синдрома усталости с другими симптомами «долгого COVID-19», в том числе с одышкой.…”

Long covid and mental and physical health: A cross‐sectional study of adults in California

“…Some of the common mental health issues that COVID-19 survivors have reported include post-traumatic stress disorder, depression, and anxiety disorders [1,9]. Overall, reviews have shown that long covid affects a variety of symptoms, including mental health, gastrointestinal, cardiopulmonary, and neurological, without a clear etiological explanation [10,11]. However, with SARS-CoV-2 being a novel virus, the long-term effects of COVID-19 on survivors are still being uncovered [1].…”
