Kidney Function Affects Short-Term Stroke Outcomes

My reading into this is that kidney treatment somehow takes a back seat after a stroke. With these scores is the success rate better or worse than standard patients that come in with these scores? This analysis is what should have been done rather than telling us nothing useful.

A routine blood test that measures kidney function can be a valuable predictor of short-term outcomes for patients who have experienced a stroke, according to a study published in the February issue of the journal Stroke.
Nada El Husseini, MD, Wake Forest School of Medicine, Winston-Salem, North Carolina, and colleagues analysed data on more than 232,000 patients aged 65 years and older who had experienced an ischaemic stroke and were admitted to 1,581 US hospitals over a 3-year period.
The researchers found that those patients with renal dysfunction upon admission, as indicated by the estimated glomerular filtration rate (eGFR) and basic demographic information such as age, race, and sex, were significantly more likely to die while hospitalised and far less likely to be discharged home.
“Kidney disease is frequently a comorbidity in patients with acute ischaemic stroke,” said Dr. El Husseini. “This one test done on admission to measure kidney function can be used to better inform patients with ischaemic stroke and their families about what to expect.”
The they study, the researchers found that in-hospital mortality was most common (29.2%) among patients with eGFR scores ≤15 without dialysis and least common (9.1%) among those with scores ≥60.
The data also revealed that discharge home was most common (42.8%) among the patients with eGFR scores ≥60 and least common (23.5%) among those with scores of ≤15 without dialysis. The findings regarding those with eGFR scores between 16 and 59 followed similar trends in short-term outcomes, with higher scores correlating to lesser risk of in-hospital mortality and greater odds of being discharged home.
“Any renal dysfunction was associated with increased risk of inpatient mortality and any eGFR less than 30 with lower likelihood of being discharged home,” said Dr. El Husseini. “Kidney function is clearly an important factor in stroke patients.”
Because the study was limited to Medicare patients aged 65 years and older who were admitted to facilities participating in a voluntary nationwide quality-improvement program, the research results may not be directly applicable to other populations, noted Dr. El Husseini.
But future research in this area might “determine if specific interventions could further influence short-term outcomes following stroke in those with kidney disease,” she said.
