SARS-CoV-2 has caused over 6.9 million deaths and continues to produce lasting health consequences. COVID-19 manifests broadly from no symptoms to death. In a retrospective cross-sectional study, we developed personalized risk assessment models that predict clinical outcomes for individuals with COVID-19 and inform targeted interventions. We sequenced viruses from SARS-CoV-2-positive nasopharyngeal swab samples between July 2020 and July 2022 from 4450 individuals in Missouri and retrieved associated disease courses, clinical history, and urban-rural classification. We integrated this data to develop machine learning-based predictive models to predict hospitalization, ICU admission, and long COVID.The mean age was 38.3 years (standard deviation = 21.4) with 55.2% ( = 2453) females and 44.8% ( = 1994) males (not reported, = 4). Our analyses revealed a comprehensive set of predictors for each outcome, encompassing human, environment, and virus genome-wide genetic markers. Immunosuppression, cardiovascular disease, older age, cardiac, gastrointestinal, and constitutional symptoms, rural residence, and specific amino acid substitutions were associated with hospitalization. ICU admission was associated with acute respiratory distress syndrome, ventilation, bacterial co-infection, rural residence, and non-wild type SARS-CoV-2 variants. Finally, long COVID was associated with hospital admission, ventilation, and female sex.Overall, we developed risk assessment models that offer the capability to identify patients with COVID-19 necessitating enhanced monitoring or early interventions. Of importance, we demonstrate the value of including key elements of virus, host, and environmental factors to predict patient outcomes, serving as a valuable platform in the field of personalized medicine with the potential for adaptation to other infectious diseases.
SARS-CoV-2 已导致超过 690 万人死亡,并持续造成持久的健康影响。COVID-19 的表现从无症状到死亡不等。在一项回顾性横断面研究中,我们开发了个性化风险评估模型,用于预测 COVID-19 患者的临床结局,并为有针对性的干预措施提供信息。我们对 2020 年 7 月至 2022 年 7 月期间密苏里州 4450 名个体的 SARS-CoV-2 阳性鼻咽拭子样本进行了病毒测序,并获取了相关疾病过程、临床病史和城乡分类。我们整合了这些数据,开发了基于机器学习的预测模型,以预测住院、入住 ICU 和长新冠。平均年龄为 38.3 岁(标准差=21.4),女性占 55.2%(=2453),男性占 44.8%(=1994)(未报告,=4)。我们的分析揭示了每个结局的一套全面预测因子,包括人类、环境和病毒全基因组遗传标记。免疫抑制、心血管疾病、年龄较大、心脏、胃肠道和全身症状、农村居住和特定氨基酸取代与住院有关。入住 ICU 与急性呼吸窘迫综合征、通气、细菌合并感染、农村居住和非野生型 SARS-CoV-2 变体有关。最后,长新冠与住院、通气和女性有关。总体而言,我们开发了风险评估模型,能够识别需要加强监测或早期干预的 COVID-19 患者。重要的是,我们证明了包括病毒、宿主和环境因素的关键要素来预测患者结局的价值,为个性化医学领域提供了一个有价值的平台,并有潜力适应其他传染病。
