Incorporating the number of COVID-19 infections in the past year showed improved prediction performance and should be considered in future models for kidney disease prediction.
[...] In our study, we emulated a prospective cohort design with a recruitment start date of 07/01/2022 and a follow-up end date of 03/31/2024, which defined the cohort follow-up period (Fig. 2b). The first hospital visit (either inpatient or outpatient) after the study start date was defined as the index date for each patient. We defined two prediction windows starting the index date: 1 month and 1 year. During each prediction window, we assessed two separate kidney outcomes: (1) AKI, identified by International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code N17, and (2) chronic kidney disease (CKD), identified by ICD-10-CM code N18.
