Background Variable standards of care may contribute to poor outcomes associated with AKI. We evaluated whether a multifaceted intervention (AKI e-alerts, an AKI care bundle, and an education program) would improve delivery of care and patient outcomes at an organizational level. Methods A multicenter, pragmatic, stepped-wedge cluster randomized trial was performed in five UK hospitals, involving patients with AKI aged $18 years. The intervention was introduced sequentially across fixed three-month periods according to a randomly determined schedule until all hospitals were exposed. The primary outcome was 30-day mortality, with pre-specified secondary endpoints and a nested evaluation of care process delivery. The nature of the intervention precluded blinding, but data collection and analysis were independent of project delivery teams. Results We studied 24,059 AKI episodes, finding an overall 30-day mortality of 24.5%, with no difference between control and intervention periods. Hospital length of stay was reduced with the intervention (decreases of 0.7, 1.1, and 1.3 days at the 0.5, 0.6, and 0.7 quantiles, respectively). AKI incidence increased and was mirrored by an increase in the proportion of patients with a coded diagnosis of AKI. Our assessment of process measures in 1048 patients showed improvements in several metrics including AKI recognition, medication optimization, and fluid assessment. Conclusions A complex, hospital-wide intervention to reduce harm associated with AKI did not reduce 30-day AKI mortality but did result in reductions in hospital length of stay, accompanied by improvements in in quality of care. An increase in AKI incidence likely reflected improved recognition.

Visceral adiposity remains a strongly significant indicator of insulin resistance in WHO grade III obesity. Neck circumference surpasses other anthropometric measurements as a powerful marker of both VAT and insulin resistance.

Erectile dysfunction (ED) has been associated with risk factors for atherosclerosis. Medications used for atherosclerosis have also been implicated in ED. The aim of this study is to investigate the relationship of erectile function to cardiovascular risk factors and specific drug therapies before and after 6 months of statin therapy. In this prospective observational study, International Index of Erectile Function (IIEF) scores were measured in 93 men attending cardiovascular risk clinics. Cardiovascular risk factors and drug therapies were assessed prior to initiation and after 6 months of statin therapy. Prior to statin therapy, the median IIEF score was 21 (range 0-25), and 57% had impairment of erectile function. After statin therapy, IIEF scores were reduced to 6.5 (range 0-25) (p < 0.001), and 22% experienced new onset ED. Before statin therapy no correlation was observed between IIEF score and any individual cardiovascular risk factor. After 6 months of statin therapy, correlations were observed between lower IIEF scores (r = 0.62; p < 0.001) and age and diabetes and weakly with smoking. Differences in dose, relative efficacy or relative lipophilicity of statin prescribed showed no correlation with change in IIEF score. This study suggests ED following statin therapy is more likely in patients with severe endothelial dysfunction due to established cardiovascular risk factors including age, smoking and diabetes.
