OBJECTIVES: To generate real-world evidence on all-cause mortality and economic burden of Clostridioides difficile infections (CDIs) and recurrences (rCDIs) in England. METHODS: We conducted a cohort study using retrospective data from Clinical Practice Research Datalink linked to Hospital Episode Statistics. Patients diagnosed with CDI in hospital and community settings during 2015-2018 were included and followed for ≥1 year. All-cause mortality was described at 6, 12, and 24 months. Healthcare resource usage (HCRU) and associated costs were assessed at 12 months of follow-up. A cohort of non-CDI patients, matched by demographic and clinical characteristics including Charlson Comorbidity Index score, was used to assess excess mortality and incremental costs of HCRU. RESULTS: All-cause mortality among CDI patients at 6, 12, and 24 months was 15.87%, 20.37%, and 27.03%, respectively. A higher proportion of rCDI patients died at any point during follow-up. Compared with matched non-CDI patients, excess mortality was highest at 6 months with 1.81 and 2.53 deaths per 100 patient-months among CDI and ≥1 rCDI patients. Hospitalizations were the main drivers of costs, with an incremental cost of £1209.21 per CDI patient. HCRU and costs increased with rCDIs. CONCLUSION: CDI poses a substantial mortality and economic burden, further amplified by rCDIs.
目的:获取关于英格兰艰难梭菌感染(CDI)及复发感染(rCDI)的全因死亡率和经济负担的真实世界证据。 方法:我们利用与医院事件统计数据相链接的临床实践研究数据链中的回顾性数据进行了一项队列研究。纳入了2015年至2018年期间在医院和社区环境中被诊断为CDI的患者,并对其进行了≥1年的随访。在6个月、12个月和24个月时描述全因死亡率。在随访12个月时评估医疗资源使用(HCRU)及相关成本。使用一组按人口统计学和临床特征(包括Charlson合并症指数评分)匹配的非CDI患者队列来评估额外死亡率和HCRU的增量成本。 结果:CDI患者在6个月、12个月和24个月时的全因死亡率分别为15.87%、20.37%和27.03%。较高比例的rCDI患者在随访期间的任何时间点死亡。与匹配的非CDI患者相比,额外死亡率在6个月时最高,CDI患者和≥1次rCDI患者中每100患者月分别有1.81例和2.53例死亡。住院是成本的主要驱动因素,每位CDI患者的增量成本为1209.21英镑。HCRU和成本随着rCDI的发生而增加。 结论:CDI造成了巨大的死亡率和经济负担,rCDI进一步加剧了这种负担。
