Thus, we estimated the association between eGFR and both readmission and mortality and identified diagnoses for readmission.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Adults discharged from hospitals in Alberta, Canada, from 2005 to 2021 were included.

The primary outcome was unplanned readmission or death within 30 days of discharge. Multivariable logistic regression, accounting for multiple admissions per participant, was used to estimate unadjusted and adjusted odds ratios (aOR) of the primary outcome, using G1\u20132 as the reference. The results were stratified by age and sex. The type and frequency of each unplanned readmission was also determined.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The cohort comprised 2,992,810 admissions among 1,249,248 participants (median [interquartile range] admission per participant: 1 [1\u20133] admission; age: 61 [47\u201374] years). Among lower eGFR categories, heart failure was the most common readmission diagnosis, followed by AKI. Relative to G1\u20132, more impaired eGFR groups had significantly higher odds of the primary outcome, with the highest adjusted odds experienced by the G1T\u20135T group (aOR, 1.47; 95% confidence interval, 1.12 to 1.93) and G5ND group (aOR, 1.40; 95% confidence interval, 1.34 to 1.47). Stratified analyses showed that individuals younger than 65 years and females with reduced eGFR had higher odds compared with counterparts in the G1\u20132 reference group.<\/jats:p>\n
