BCN HEALTH publishes a study evaluating the relationship between kidney failure, heart diseases and the occurrence of hyperkalemia

BCN HEALTH analyzed the relationship between kidney failure, heart diseases, and the occurrence of hyperkalemia using a fuzzy regression discontinuity design. Hyperkalemia, a condition characterized by elevated potassium levels, is often associated with chronic kidney disease, heart failure, and related comorbidities. By leveraging the inherent diagnostic potassium thresholds (5.5 and 6 mEq/L), this research examines how these conditions influence hyperkalemia diagnoses. The study utilized data from the BIG-PAC database, encompassing 1.9 million anonymized patient records from healthcare centers across Spain. Adult patients diagnosed with hyperkalemia (mild to severe) between 2011 and 2018 were included. Sociodemographic factors, clinical diagnoses, and comorbid conditions such as hypertension, diabetes, and depression were analyzed alongside potassium levels.

Key findings reveal a significant association between hyperkalemia and kidney failure diagnoses, with a 11.2% increased likelihood at a potassium threshold of 6 mEq/L. Similarly, heart disease diagnoses showed a 12.4% increased probability of being linked with hyperkalemia at this threshold. Other notable associations include a 6.8% higher risk in patients with hypertension and an 8.8% increased likelihood in those with depression. However, results for the lower threshold (5.5 mEq/L) lacked statistical significance.

The study underscores the critical need for enhanced monitoring of patients with kidney failure or heart disease to prevent hyperkalemia-related complications. By identifying and managing risk factors proactively, healthcare providers can mitigate severe outcomes, such as arrhythmias, and reduce overall healthcare resource utilization.
