Background
Several reports suggested that compliance with acute kidney injury care bundles among hospitalized patients resulted in improved kidney and patient outcomes. We investigated the effect of acute kidney injury care bundle utilization on the incidence of acute kidney injury and renal outcomes in a large cohort of myocardial infarction patients treated with percutaneous coronary intervention.
Methods
We included patients with myocardial infarction admitted following percutaneous coronary intervention between January 2008 and December 2020. From January 2016, acute kidney injury care bundle was implemented in our cardiac intensive care unit. Acute kidney injury care bundle consisted of simple standardized investigations and interventions, including strict monitoring of serum creatinine and urine analysis, planning investigations, treatment, and guidance about seeking nephrologist advice. Patients' records were evaluated for the occurrence of acute kidney injury, its severity, and recovery, before and after the implementation of acute kidney injury care bundle.
Results
We included 2646 patients (1941 patients in the years 2008–2015 and 705 patients in the years 2016–2020). Implementation of care bundles resulted in a significant decrease in the occurrence of acute kidney injury from 190/1945 to 42/705 (10–6%; p < 0.001), with a trend for lower acute kidney injury score > 1 (20% vs. 25%; p = 0.07) and higher acute kidney injury recovery (62% vs. 45%, p = 0.001). Using a multivariable regression model, the use of care bundles resulted in a 45% decrease in the relative risk for acute kidney injury (HR 0.55, 95% CI 0.37–0.82, p < 0.001).
Conclusion
Among patients with ST-elevation myocardial infarction, treated with percutaneous coronary intervention and admitted to our cardiac intensive care unit over the period January 2008–December 2020, compliance with acute kidney injury care bundle was independently associated with a significant decrease in occurrence of acute kidney injury and with better renal outcomes following acute kidney injury. Further interventions, such as e-alert systems for acute kidney injury, could improve utilization of the acute kidney injury care bundle and optimize its clinical benefits.
