Evidence-based intervention designed to improve care for acute kidney injury (AKI) patients was linked to reductions in the length of hospital stay, shorter duration of AKI episodes, and an increase in AKI incidence that likely reflected improved recognition, stated new study. The intervention also led to improvements in several metrics related to AKI care, including AKI recognition, medication optimization, and fluid assessment by clinicians.
Acute kidney injury (AKI), an abrupt or rapid decline in kidney function, is an increasingly prevalent and potentially serious condition that often arises due to certain health problems or medical treatments that deprive the kidneys of normal blood flow or damage kidney tissue. A new study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN) may help improve the diagnosis and treatment AKI.
AKI frequently complicates hospitalizations and it is linked to elevated mortality risks, longer-term kidney damage, longer hospital stays, and increased healthcare costs. Because AKI often occurs with few symptoms it can go unrecognized, leading to differences in the delivery of standard AKI treatment as recommended in national and international guidelines.
In 5 hospitals in the United Kingdom, the intervention was introduced sequentially according to a randomly determined schedule across 3-month periods. The team studied 24,059 AKI episodes and found that although the intervention did not alter 30-day mortality rates, it was associated with reductions in length of hospital stay, shorter duration of AKI episodes, and an increase in AKI incidence that likely reflected improved recognition. The intervention led to improvements in several metrics related to AKI care, including AKI recognition, medication optimization, and fluid assessment by clinicians.
"We have shown that AKI recovers more quickly and that some people can go home from hospital earlier, albeit that this approach didn't have any effect on survival rates," said Dr. Selby. " He noted that the reduction in hospital length of stay seen in this study could translate into a significant health economic benefit, given the large numbers of people who develop AKI.
