BackgroundThe post-discharge prognosis of patients with sepsis remains a crucial issue; however, few studies have investigated the relationship between pre-sepsis health status and subsequent prognosis in a large population. This study aimed to examine the effect of the pre-sepsis care needs level on changes in care needs and mortality in patients with sepsis 1 year post-discharge.MethodsThis was a population-based retrospective cohort study including twelve municipalities in Japan that participated in the Longevity Improvement & Fair Evidence study between April 2014 and March 2022, with a total of 1,491,608 persons. The pre-hospitalization levels of care needs (baseline) were classified from low to high, as no care needs, support level and care needs level 1, care needs levels 2-3, and care needs levels 4-5 (fully dependent). The outcomes were changes in care needs level and mortality 1 year post-discharge, assessed by baseline care needs level using Cox proportional hazard models.ResultsThe care needs levels of 17,648 patients analyzed at baseline were as follows: no care needs, 7982 (45.2%); support level and care needs level 1, 3736 (21.2%); care needs levels 2-3, 3089 (17.5%); and care needs levels 4-5, 2841 (16.1%). At 1 year post-discharge, the distribution of care needs were as follows: no care needs, 4791 (27.1%); support level and care needs level 1, 2390 (13.5%); care needs levels 2-3, 2629 (14.9%); care needs levels 4-5, 3373 (19.1%); and death, 4465 (25.3%). Patients with higher levels of care needs exhibited an increased association of all-cause mortality 1 year post-discharge after adjusting for confounders [hazard ratios and 95% confidence intervals: support level and care needs level 1, 1.05 (0.96, 1.15); care needs levels 2-3, 1.46 (1.33, 1.60); and care needs levels 4-5, 1.92 (1.75, 2.10); P for trend < 0.001].ConclusionsElevated care needs and mortality were observed in patients with sepsis within 1 year post-discharge. Older patients with sepsis and higher baseline levels of care needs had a high association of all-cause mortality 1 year post-discharge.© 2024. The Author(s).
