Body Composition, Kidney Size, and Medication Dosing in Acute Kidney Injury: Follow-Up at 90 Days and 12 Months

Sponsor: Hannover Medical School

Summary

Acute Kidney Injury (AKI) is a common and serious condition affecting up to 12% of hospitalized patients, with increasing severity linked to higher mortality. Despite early detection via automated warning systems, clinical outcomes such as hospital length of stay, dialysis need, and death remain suboptimal. This non-interventional study evaluates modifiable factors influencing AKI outcomes by integrating four key components: body composition, kidney size, medication dosing, and patient-reported outcomes. Body composition is assessed using non-invasive bioimpedance spectroscopy to evaluate fluid status, muscle mass, and fat mass. Kidney size and structure are assessed via point-of-care ultrasound to detect underlying chronic kidney disease or obstructive causes. A standardized national medication plan is used to review drug dosing, interactions, and potential errors, supported by nephrology and pharmacy expertise. Additionally, patients are contacted by telephone at 90 and 365 days post-diagnosis to assess awareness of AKI, perceived severity, health literacy, and current kidney function (via blood tests and medication review). The study evaluates whether early, multidimensional assessment is associated with improved patient understanding, care coordination, and long-term outcomes. Findings may inform future strategies to enhance AKI management, reduce complications, and improve patient-centered care.
