Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Aggressive cardivascular risk factor and lifestyle modification utilising nurse led co-ordinated care. The trial clinic will be additional to the patients' usual medical care. The trial clinic will use a co-ordinated care approach to achieving cardiovascular risk factor modification and include a significant lifestyle and diet modification component customized to the patients' health care needs. There will be focus on patient self-management and motivation for sustainable behavior change. Patients will be followed for up to 3 years. For patients in the Nurse coordinated care arm, they will be seen for an initial assessment (approximately 1 hour) about 2 weeks after enrollment. Then out to monthly or further apart follow up (half hour session) depending on their needs and stage of chronic kidney disease (CKD). These visits with the nurses alternate with visits to Nephrology outpatients department (shared care). This for the duration of the trial which is 3 years.

Summary
Brief summary
Chronic kidney disease (CKD) is associated with a twenty-fold increase in the death from heart and blood vessel disease (cardiovascular disease -CVD). Patients with CKD have multiple risk factors for CVD and
include high cholesterol, hypertension, anaemia, abnormalities of blood chemistry, diabetes, obesity and sedentary lifestyle. Intervention may decrease the progression of CVD and treatment guidelines have been
developed. However, patients with CKD have complex health issues and audit data suggests that within the current model of care, many do not reach treatment targets.
Co-ordinated care clinics utilizing a nurse led, case management approach and a multidisciplinary team have been demonstrated to optimize CKD care and decrease progression of kidney dysfunction. However, the impact on progression of CVD has not been studied.
The hypothesis of this proposal is therefore:
Nurse led co-ordinated care approach to cardiovascular risk factor and lifestyle modification will reduce the progression of CVD when compared with standard care, in patients with CKD. Additional hypotheses are: The nurse led clinic improves service quality and patient satisfaction AND This model of care will be cost effective.
