However, the actual incidence of AKI in hospitalized patients with ERM along with the contributing cofactors that may increase the risk of AKI have rarely been investigated.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi240849-5\"><jats:title>Objectives<\/jats:title><jats:p>To examine the incidence of kidney injury in hospitalized patients with ERM and to identify additional cofactors that might contribute to the development of kidney injury in patients with ERM.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi240849-6\"><jats:title>Design, Setting, and Participants<\/jats:title><jats:p>This retrospective cohort study was conducted in a diverse community population of patients 18 years or older with ERM who were hospitalized across Kaiser Permanente Northern California between January 1, 2009, and December 31, 2019. Patients were initially identified through electronic screening for all-cause rhabdomyolysis admissions, followed by manual medical record reviews to verify their eligibility for the study. The diagnosis of AKI and chronic kidney disease (CKD) was determined using KDIGO (Kidney Disease Improving Global Outcomes) criteria and confirmed by medical record review. Data analysis was performed from October 1, 2023, to January 31, 2024.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi240849-7\"><jats:title>Exposures<\/jats:title><jats:p>History of strenuous physical exercise before hospitalization for ERM.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi240849-8\"><jats:title>Main Outcome and Measures<\/jats:title><jats:p>Development of AKI, CKD, and compartment syndrome and number of deaths.<\/jats:p><\/jats:sec><jats:sec id=\"ab-zoi240849-9\"><jats:title>Results<\/jats:title><jats:p>Among 3790 patients hospitalized for rhabdomyolysis between 2009 and 2019 in Kaiser Permanente Northern California, 200 (mean [SD] age, 30.5 [8.5] years; 145 [72.5%] male) were confirmed to have ERM via medical record review. Seventeen patients (8.5%) developed AKI, none developed CKD, 1 (0.5%) developed compartment syndrome, and there were no fatalities. There was no association between serum CK levels and the risk of AKI. However, the risk of AKI was significantly higher in patients with ERM who used nonsteroidal anti-inflammatory drugs (NSAIDs) before admission (11 of 17 with AKI [64.7%] vs 40 of 183 without AKI [21.9%], <jats:italic>P<\/jats:italic>\u2009&amp;amp;lt;\u2009.001) or experienced dehydration (9 of 183 without AKI [52.9%] vs 9 of 17 with AKI [4.9%], <jats:italic>P<\/jats:italic>\u2009&amp;amp;lt;\u2009.001).
