Clinical Trials

Providing Resources to Enhance Patients' Readiness to Make Decisions About Kidney Disease: The PREPARE NOW Study (PREPARE NOW)  https://clinicaltrials.gov/show/NCT02428569

Research Interests

Outcomes in Chronic Kidney Disease and Dialysis, Cardiovascular Disease, Peripheral Arterial Disease 

Research Summary

Research in the Bernard Jaar Lab focuses on health related outcomes in chronic kidney disease and end-stage kidney disease. We are interested in comparison of survival and quality of life outcomes between dialysis modalities, better understanding of causes and patients characteristics and outcomes associated with hospital readmissions in chronic kidney disease. Our research also focuses on outcomes associated with cardiovascular disease and specifically peripheral arterial disease in this high risk population.
