Cumulative incidence of the primary outcome of an outpatient serum creatinine and an outpatient follow-up visit with a health care provider at one year according to four key predictors. Panel A: Severity of acute kidney injury - Individuals with a maximum severity of AKI stage III were 1.47 (95% CI 1.23–1.76) times more likely to have follow-up within one year compared to those with a maximum of stage II AKI (P < 0.001). Panel B: Charlson Comorbidity Index – Individuals with a greater comorbidity burden were more likely to receive follow-up (HR 1.04 for each point increase, 95% CI 1.02, 1.07; P = 0.001). Panel C: Discharge eGFR– Individuals with worse kidney function at discharge were more likely to receive follow-up (HR 0.92 per 10mL/min/1.73m2 increase in eGFR, 95% CI 0.89, 0.95; P < 0.001). Panel D: Length of hospitalization – Individuals with longer hospitalizations were more likely to have follow-up (HR 1.06 per week increase in length of stay, 95% CI 1.02, 1.11; P = 0.006). SCr: Serum creatinine; AKI: Acute kidney injury; eGFR: estimated glomerular filtration rate; LOS: Length of stay.
