To assess clinical and epidemiological trends of severe sepsis.
Ecological study of patients presenting to the emergency department with severe sepsis or septic shock between 2005 and 2013. Patients were identified using the state-wide hospital administrative database. Key outcomes included incidence rates (IRs) and mortality rates (per 1000 population) by age and medically underserved areas (MUAs), sepsis case fatality rate (deaths per 100 sepsis cases), and proportions of transfer and comorbidities.
There were 154 019 sepsis cases identified. In 2005, 85+ yo in non-MUAs had a 44% increase in IR compared with those in MUAs, and this difference rose to 74% by 2013. Mortality rates were 1.6 (95% CI 1.3 to 1.8) times greater among 85+ yo in non-MUAs. Mortality rates increased by 1.8% annually, while the sepsis case fatality rate decreased by 7.7%. The proportion of transfer among sepsis cases decreased by 2.1% per year (3.8% in non-MUAs, 0.7% in MUAs).
Sepsis incidence varies geographically, and access to healthcare is one proposed mechanism that may explain heterogeneity. Over time, we may be capturing higher acuity sepsis cases with better recognition and management, as well as observing differential diagnostic coding documentation by location.
评估严重脓毒症的临床和流行病学趋势。
对 2005 年至 2013 年间在急诊科就诊的严重脓毒症或感染性休克患者进行的生态学研究。使用全州医院管理数据库来识别患者。主要结局包括按年龄和医疗服务不足地区(MUA)划分的发病率(IR)和死亡率(每千人人口)、脓毒症病死率(每 100 例脓毒症病例的死亡人数)以及转移比例和合并症。
共确定了 154019 例脓毒症病例。2005 年,非 MUA 地区 85 岁以上人群的 IR 比 MUA 地区增加了 44%,到 2013 年,这一差异上升至 74%。非 MUA 地区 85 岁以上人群的死亡率高 1.6 倍(95%CI 1.3 至 1.8)。死亡率每年增加 1.8%,而脓毒症病死率则下降了 7.7%。脓毒症病例的转移比例每年下降 2.1%(非 MUA 地区为 3.8%,MUA 地区为 0.7%)。
脓毒症的发病率存在地域差异,而获得医疗保健可能是造成这种异质性的一个原因。随着时间的推移,我们可能会通过更好的识别和管理来捕获更高危的脓毒症病例,同时也会观察到地理位置不同的诊断编码文件的差异。
