Abstract

Background: We assessed the healthcare and economic burden of sepsis in adult hospitalised patients in Wales, UK. Methods: We analysed hospital admissions to all acute hospitals in Wales via the Secure Anonymised Information Linkage Databank. We included all adult patients, 2006–2018, with an inpatient admission including one or more explicit sepsis codes. Results: 38,564 patients had at least one admission for sepsis between 2006 and 2018. Most persons (86.7%) had just one admission. 3398 patients (8.4%) were admitted to ICU. The number of admissions increased yearly over the study period from 1548 in 2006 to 8708 in 2018. The largest annual increase (141.7% compared to the previous year) occurred in 2017. Admission numbers increased disproportionately amongst patients with high levels of comorbidities, but changes were consistent across all age groups, areas of deprivation and ICU admissions. Estimated inpatient sepsis costs were £340.34 million in total during the study period. The average cost per hospital spell was £7270. Patients readmitted to the hospital for sepsis amassed estimated treatment costs of over £72 million during the study period. Out of the 38,564 persons, 21,275 (55.2%) died within 3 years of their first admission. Inpatient mortality halved from 40.5% to 19.5%, and there was a trend towards reduced mortality at 6 months, 1 and 3 years post hospital discharge. Conclusion: Sepsis related hospital admissions are increasing over time and still likely to be underreported. Although mortality appears to have fallen, prolonged hospitalisation and readmissions place a significant burden on healthcare system resources and costs.
