与脓毒症前医疗保健利用率相比，确定脓毒症后医疗保健利用率增加的频率和风险因素。回顾性观察队列研究。2016-2019 年 MarketScan 商业和医疗补助数据库。脓毒症儿童（0-18 岁）接受治疗美国医院。无。我们测量了脓毒症住院后 90 天与住院前 90 天内医疗保健利用率增加的频率和风险因素。我们将医疗保健利用增加定义为基于门诊、急诊和住院住院时间，与住院前 90 天相比，住院后 90 天的时间增加至少 3 天。我们确定了 2801 名因脓毒症住院的患者，其中 865 名 (30.9%) 患者在脓毒症后增加了医疗保健利用率，脓毒症前 90 天的中位数（四分位距 [IQR]）为 3 天 (1-6 天)脓毒症后 90 天总计 10 天（IQR，6-21 天）（p < 0.001）。在多变量模型中，住院时间较长的儿童（> 30 天调整优势比 [aOR]，4.35；95% CI，2.99-6.32）和患有复杂慢性病（特别是肾病）的儿童增加医疗保健使用的几率较高（aOR，1.47；95% CI，1.02-2.12）、血液学/免疫学（aOR，1.34；95% CI，1.03-1.74）、代谢性（aOR，1.39；95% CI，1.08-1.79）和恶性肿瘤（aOR，1.34；95% CI，1.03-1.74） ，1.89；95% CI，1.38-2.59）。在美国败血症住院的这一具有全国代表性的儿童队列中，近三分之一的人在出院后 90 天内增加了医疗保健利用率。住院时间超过 30 天且患有复杂慢性病的儿童更有可能获得更多的医疗保健利用率。版权所有 © 2024，重症监护医学协会和 Wolters Kluwer Health, Inc. 保留所有权利。

To determine the frequency of and risk factors for increased post-sepsis healthcare utilization compared with pre-sepsis healthcare utilization.Retrospective observational cohort study.Years 2016-2019 MarketScan Commercial and Medicaid Database.Children (0-18 yr) with sepsis treated in a U.S. hospital.None.We measured the frequency of and risk factors for increased healthcare utilization in the 90 days post- vs. pre-sepsis hospitalization. We defined increased healthcare utilization as an increase of at least 3 days in the 90 days post-hospitalization compared with the 90 days pre-hospitalization based on outpatient, emergency department, and inpatient hospitalization. We identified 2801 patients hospitalized for sepsis, of whom 865 (30.9%) had increased healthcare utilization post-sepsis, with a median (interquartile range [IQR]) of 3 days (1-6 d) total in the 90 days pre-sepsis and 10 days (IQR, 6-21 d) total in the 90 days post-sepsis ( p < 0.001). In multivariable models, the odds of increased healthcare use were higher for children with longer lengths of hospitalization (> 30 d adjusted odds ratio [aOR], 4.35; 95% CI, 2.99-6.32) and children with preexisting complex chronic conditions, specifically renal (aOR, 1.47; 95% CI, 1.02-2.12), hematologic/immunologic (aOR, 1.34; 95% CI, 1.03-1.74), metabolic (aOR, 1.39; 95% CI, 1.08-1.79), and malignancy (aOR, 1.89; 95% CI, 1.38-2.59).In this nationally representative cohort of children who survived sepsis hospitalization in the United States, nearly one in three had increased healthcare utilization in the 90 days after discharge. Children with hospitalizations longer than 30 days and complex chronic conditions were more likely to experience increased healthcare utilization.Copyright © 2024 by the Society of Critical Care Medicine and Wolters Kluwer Health, Inc.
