Chronic kidney disease (CKD) is a condition that affects many individuals worldwide, and the risks associated with advanced stages of CKD are significant. According to a recent retrospective study presented at the National Kidney Foundation (NKF) Spring Clinical meeting, patients with stage 5 CKD faced a 40% higher chance of being hospitalized for gastrointestinal (GI) bleeding compared to those without CKD. Additionally, these patients had higher rates of inpatient all-cause mortality, with those on dialysis having a particularly high risk.
The study highlighted the importance of early endoscopic evaluations in determining patient outcomes. Patients with stage 5 CKD had significantly fewer early endoscopies and more delayed endoscopies, which were associated with a 60% higher chance of mortality. The delay in endoscopic evaluations could be a contributing factor to the increased risk of mortality in CKD patients, especially those on dialysis with multiple comorbidities.
Despite international consensus guidelines recommending endoscopy within 24 hours for patients with acute upper GI bleeding, this does not always happen in clinical practice. Factors such as previous procedures, electrolyte imbalances, dialysis schedules, and thrombocytopenia can influence the decision-making process regarding the timing of endoscopy. Understanding the reasons for delayed evaluations in CKD patients is crucial for improving adherence to guidelines and ultimately patient outcomes.
Differences in GI Bleeding Risk Among CKD Patients
The study also found that CKD patients on dialysis had higher rates of various interventions, including angiograms, ventilation, vasopressor use, blood transfusion, and prolonged hospitalizations. They were also more likely to experience GI bleeding caused by ulcers or other unspecified causes. Stage 5 CKD patients, regardless of dialysis status, were at a higher risk for angiodysplasia-related bleeding, while kidney transplant recipients had an increased risk for diverticular bleeding.
While the study provided valuable insights into the risks associated with advanced CKD and GI bleeding, there were limitations to the analysis. Factors such as anesthesia complications, electrolyte imbalances, and other patient-specific characteristics were not captured in the study. Future research should focus on understanding the reasons behind delayed endoscopic evaluations in CKD patients to improve adherence to guidelines and optimize patient outcomes.
The study sheds light on the complex relationship between advanced CKD and gastrointestinal bleeding, emphasizing the need for early interventions and adherence to clinical practice guidelines. By addressing the challenges faced by CKD patients in accessing timely and appropriate care, healthcare providers can potentially reduce the risk of GI bleeding-related complications and improve overall patient outcomes.
