To identify those with kidney disease early and thus facilitate earlier instigation of disease-progression slowing treatments, new definitions of chronic kidney disease (CKD) were introduced in 2002 (KDOQI). After this, the worldwide introduction of estimated glomerular filtration rate (eGFR) reporting (2006 onwards), also facilitated more widespread identification of those with CKD. Prognosis in those with CKD identified in this way was not known and the numbers with CKD appeared higher than originally expected. This thesis aimed to improve understanding of outcomes in those who met the definition of chronic kidney disease and facilitate better directed care. Data-linkage of several healthcare datasets including to laboratory, morbidity and mortality healthcare data for individuals in the Grampian region with measures of renal function in 2003 allowed those aims to be addressed. Patterns in the testing of kidney function over time were also described. Mortality and RRT initiation during the GLOMMS-I cohort's 6.5 years of follow-up were described, as were variables that were associated with these outcomes. Other measures of decline of kidney function over time (progression), were explored and compared to the ultimate measure of progression - the initiation of RRT. Various models to predict outcomes (RRT initiation, mortality and survival) were explored. Measures of model performance including discrimination, calibration, goodness of model fit and predictive performance were described. Overall the aim of this thesis was met - to improve the understanding of the prognosis of those currently labelled with chronic kidney disease. The work in this thesis has also provided the necessary information to plan and start a much wider population based study of outcome in those both with and without CKD (GLOMMS-II).
