What interventions should be recommended to improve assessment and support of patients after AKI?\n\nParticipants will be asked to do one or more of:\n\n* blood tests to measure kidney function in different ways\n* have measurement of their body composition\n* complete questionnaires about their symptoms\n* have an interview with a researcher about their experiences\n* discussion to develop an action plan based on findings",[165],"Acute Kidney Injury",[167,168,169],"acute kidney injury","chronic kidney disease","patient reported outcome measures","2026-05-01",{"date":172,"type":173},"2026-05-06","ACTUAL",{"date":175,"type":173},"2026-02-16",{"date":177,"type":161},"2029-10",{"name":5,"class":6},1]
