Insurance type and sepsis-associated hospitalizations and sepsis-associated mortality among US adults: A retrospective cohort study

Table 7 Sepsis-associated mortality among uninsured patients, stratified by hospital-based rates of sepsis-associated admission or sepsis-associated mortality

Age stratum	Total cohort	Sepsis-associated admission rate			Sepsis-associated mortality rate
		Admissions to hospitals in lowest quartile	Admissions to hospitals in middle quartiles	Admissions to hospitals in highest quartile	Admissions to hospitals in lowest quartile	Admissions to hospitals in middle quartiles	Admissions to hospitals in highest quartile
18 to 64 years	1.45 (1.29 to 1.62)	3.76 (2.52 to 5.63)	1.36 (1.19 to 1.57)	1.49 (1.21 to 1.83)	1.53 (1.12 to 2.08)	1.53 (1.34 to 1.74)	1.27 (1.04 to 1.54)
65+ years	1.46 (1.12 to 1.89)	8.67 (2.33 to 32.33)	1.37 (0.98 to 1.90)	1.52 (0.96 to 2.40)	1.59 (1.06 to 2.39)	1.33 (0.90 to 1.97)	1.62 (1.11 to 2.36)

Hospitals were divided into categories by percentage of admissions involving sepsis ("sepsis-associated admission rate") and by percentage of sepsis-associated admissions dying in the hospital ("sepsis-associated mortality rate"). Hospitals were divided into quartiles and the middle two quartiles were combined. The adjusted odds ratios (95% confidence intervals) are referent to patients with any private insurance and adjusted for covariates included in the final risk-adjusting age-strata specific models (see Methods for details).
