Patients with abnormal kidney function are common in primary care, particularly in people with other long standing illnesses. Some have long standing weakness of their kidneys, others develop new kidney weakness alongside other new illnesses. Patients with weak kidneys are more likely to be admitted, spend longer in hospital or die than those with normal kidneys. Although these events are common, how kidney weakness develops in the community is not well understood and awareness is poor. Appropriate attention to patients' medical care at times of high risk may reduce new kidney weakness. We have developed an education package for community healthcare professionals. The package is designed to teach about risks of new kidney weakness, advise about how to combat them, and help prevent it occurring. This project will use a new software tool – IMPAKT EVOLVE-AKI – to extract information from primary care systems and combine this with hospital data to identify developing kidney weakness more accurately in primary care. Both elements of the study have been tested and work well. Patients have been involved in their development and will be involved in their implementation. We propose to implement the education more widely in primary care. We will test how effectively the education has been implemented and whether it has a significant effect on the number of episodes of new kidney weakness in primary care. We will need to provide this education to 36 practices to be able to determine accurately whether the programme significantly reduces new kidney weakness. Colleagues in primary care are very interested in this education programme, and we believe that a positive result will lead to wide implementation, to the benefit of patients across the UK. This study fits well with a national programme of work in this area, and this will help with wider adoption of the study findings.
