Almost half of all patients presenting with CA-AKI are already known to medical services, the majority of which have had recent measurement of renal function in a hospital setting, suggesting that AKI for at least some of these may potentially be predictable and/or avoidable.

Background.A key objective of the Nephrology Sister Centre Programme between the renal units in Cardiff and Addis Ababa, sponsored by the International Society of Nephrology, is to facilitate development of the local clinical service in Ethiopia specifically focused on the management of acute kidney injury (AKI). Objectives. To examine the relationship between AKI risk factor recognition and monitoring of renal function in three hospitals in Ethiopia. Methods. Cross-sectional data were gathered regarding renal function monitoring, recording the presence of AKI risk-associated comorbidities and prescription of nephrotoxic medications across the disciplines of medicine, surgery, obstetrics and gynaecology. Results. Patients were more likely to have their renal function checked at the hospital with specialist services. Across all centres, the highest proportion of patients who had renal function measurements were those admitted to a medical ward. There was a positive relationship between documented comorbidities and the measurement of renal function but not between the prescription of nephrotoxic drugs and measurement of renal function. Conclusion. There was great variability in the extent to which doctors recognised the presence of risk factors for the development of AKI. Failure to identify these risk factors represents a lost opportunity to identify patients at high risk of developing renal injury who would benefit from renal function monitoring.

BackgroundFew studies have evaluated the prevalence of severe hyperkalaemia in unselected patient populations. We identified all episodes of severe hyperkalaemia occurring in 1 year, and described patient demographics, clinical response and outcome. We also assessed junior doctor knowledge of its causes and significance.Materials and methodsA retrospective interrogation of the database of the regional biochemical laboratory identified all episodes of severe hyperkalaemia (K≥ 6.5 mmol/L) occurring in 2011. The understanding of trainee doctors of the importance, causes and treatment of severe hyperkalaemia was assessed by structured questionnaire.ResultsSevere hyperkalaemia was recorded in 433 samples (365 patients) giving a prevalence of 0.11%. Thirty-six per cent of episodes occurred in patients under the care of a nephrologist, who were significantly younger than those not under the care of a nephrologist. In the nephrology cohort, 86% occurred in patients with chronic kidney disease (CKD), the majority of which had CKD Stage 5. In the non-nephrology cohort, only 65% occurred in the context of CKD, which was equally distributed between Stages 3 and 5 CKD. In both patient groups, roughly 50% of episodes occurred in association with acute kidney injury (AKI). Acute mortality (death within 48 h of documented severe hyperkalaemia) was higher in the non-nephrology compared with the nephrology cohort. Time to repeat serum potassium was influenced by the clinical setting with shorter time to repeat for acute care compared with ward settings. Assessment of trainee doctor's knowledge suggested significant deficiencies in relation to severe hyperkalaemia.ConclusionsThe prevalence of severe hyperkalaemia was low and occurred predominantly in the context of CKD and/or AKI. The majority of episodes occurred in patients not under the care of a nephrologist. Variability in time to repeat serum potassium levels suggested deficiencies in care, and assessment of trainee doctor’s knowledge suggests the need for further educational initiatives to highlight its importance.

When the National Health Service began in 1948 many hospitals, large and small, had casualty departments. These were usually run by experienced and dedicated nursing staff in often inadequate accommodation. Self taught clinical assistants were in overall charge but had inexperienced, often poorly supervised junior medical staff. The departments treated patients, including children, with a wide range of trivial or serious illness and injury. In 1962, the Platt committee recommended that the renamed 'accident and emergency' departments be under the direction of orthopaedic surgeons.' However, this solution was not generally successful and in 1971 the Joint Consultants Committee under Sir John Bruce suggested that a new type of specialist be created, namely consultant in accident and emergency medicine.2 There are now over 200 such specialists in England and Wales.
