We sought to assess the impact of renal impairment on acute medical admissions and to identify potential contributory factors to admissions involving renal impairment at presentation. In a prospective cohort study, 29.5% of all acute medical emergency admissions had an eGFR < 60 ml/min/1.73m2 at presentation. Of these, 19.9 % had definite chronic kidney disease and 8.4 % had definite acute kidney injury. Detailed analysis of a random subset of patients with an eGFR <60ml/min/1.73m2 at presentation demonstrated that the major reasons for admission included falls, dehydration and fluid overload. 46% were on diuretics and 53% were on an ACEI or ARB or both. Gastrointestinal disturbance and recent medication changes were common and diuretic use persisted even with diarrhoea or vomiting.
