Do acute elevations of serum creatinine in primary care engender an increased mortality risk?
Background: The significant impact Acute Kidney Injury (AKI) has on patient morbidity and mortality emphasizes the need for early recognition and effective treatment. AKI presenting to or occurring during hospitalisation has been widely studied but little is known about the incidence and outcomes of patients experiencing acute elevations in serum creatinine in the primary care setting where people are not subsequently admitted to hospital. The aim of this study was to define this incidence and explore its impact on mortality. Methods: The study cohort was identified by using hospital data bases over a six month period. Inclusion criteria: People with a serum creatinine request during the study period, 18 or over and not on renal replacement therapy. The patients were stratified by a rise in serum creatinine corresponding to the Acute Kidney Injury Network (AKIN) criteria for comparison purposes. Descriptive and survival data were then analysed. Ethical approval was granted from National Research Ethics Service (NRES) Committee South East Coast and from the National Information Governance Board. Results: The total study population was 61,432. 57,300 subjects with ‘no AKI’, mean age 64.The number (mean age) of acute serum creatinine rises overall were, ‘AKI 1’ 3,798 (72), ‘AKI 2’ 232 (73), and ‘AKI 3’ 102 (68) which equates to an overall incidence of 14,192 pmp/year (adult). Unadjusted 30 day survival was 99.9% in subjects with ‘no AKI’, compared to 98.6%, 90.1% and 82.3% in those with ‘AKI 1’, ‘AKI 2’ and ‘AKI 3’ respectively. After multivariable analysis adjusting for age, gender, baseline kidney function and co-morbidity the odds ratio of 30 day mortality was 5.3 (95% CI 3.6, 7.7), 36.8 (95% CI 21.6, 62.7) and 123 (95% CI 64.8, 235) respectively, compared to those without acute serum creatinine rises as defined. Conclusions: People who develop acute elevations of serum creatinine in primary care without being admitted to hospital have significantly worse outcomes than those with stable kidney function
A dataset for the flood vulnerability assessment of the upper Cross River basin using morphometric analysis
The on-site collection of data is not only time consuming, but
expensive and perhaps near impossible in restive communities
within the upper Cross River basin (UCRB). Therefore, the importance
of this data cannot be overemphasized. This article presents
a Digital Elevation Model (DEM), land use and land cover (LULC)
map, soil map, geology map and climatic datasets which enhance
the understanding of the physical characteristics of the upper
Cross River basin using morphometric analysis. The use of the
LULC map, soil map and the DEM in conjunction with the climatic
data enhance the creation of the Hydrologic Response Units
(HRUs) and the water balance modelling. The simulation of the
water balance at the HRU level enables the routing of the runoff to
the reaches of the sub-basins and then to the channels. The geology
map provides confirmatory information to the morphometric
analysis. The compound factor computed from all the
derived morphometric parameters enhance the determination of
the overall flood potential of the congruent sub-basins
