PCORnet® Resources are Powering Nephrology Research for Children and Adults
PCORnet® is intended to improve the nation’s capacity to efficiently conduct patient-centered health research, particularly comparative clinical effectiveness research (CER), by providing a large, highly representative network of health data, research expertise, and patient insights. PCORnet has been developed with funding from the Patient-Centered Outcomes Research Institute® (PCORI®).

THE PCORnet® INFRASTRUCTURE SOLVES KEY CHALLENGES IN NEPHROLOGY RESEARCH
Challenge: Underpowered trials
Challenge: High participant nonadherence
Challenge: Irrelevant study outcomes
Solution: Real-world data from everyday healthcare encounters with more than 50 million people annually across the U.S.
Solution: Proven, low-burden models for pragmatic research
Solution: Patient input integrated across the study lifecycle
CASE STUDIES: NEPHROLOGY RESEARCH POWERED BY PCORnet®
Evaluating Comparative Effectiveness of Empagliflozin in Type 2 Diabetes Population With and Without Chronic Kidney Disease (Empa DKD)
Study Design: Retrospective Observational
Funder: Boehringer Ingelheim
Principal Investigator: Neha Pagidipati, Duke Clinical Research Institute
Research questions:
- Why aren’t patients with type 2 diabetes receiving guideline-recommended screening for diabetic kidney disease (DKD)?
- Which medications are safest and most effective for patients with type 2 diabetes, with or without chronic kidney disease (CKD)?
Using PCORnet, the study team:
- Used PCORnet to partner with 20 large healthcare systems
- Included 62,197 adults with type 2 diabetes with or without kidney disease
Dissemination:
- Published results in JAMA Network Open revealing CKD screening gaps and potential improvement strategies
- Published results in the Journal of the American College of Cardiology and The American Journal of Cardiology comparing medication effectiveness for kidney and heart outcomes in patients with type 2 diabetes
“PCORnet resources offer the only networked datasets out there that could support this research.”

Pediatric KIDney Stone (PKIDS) Care Improvement Network
Study Design: Prospective Observational
Funder: Patient-Centered Outcomes Research Institute® (PCORI®)
Principal Investigator: Gregory Tasian, The Children's Hospital of Philadelphia
Research question: What are the differences in stone clearance and the lived experiences of youth following ureteroscopy, shock wave lithotripsy, and percutaneous nephrolithotomy for the removal of kidney and ureteral stones?
Using PCORnet, the study team:
- Collaborated with 20 pediatric healthcare sites participating in PCORnet
- Included 1,290 youth (ages 8–21) receiving kidney stone surgery
- Co-designed with patients, caregivers, surgeons, and health systems
Dissemination:
- Published trial findings as two studies in JAMA Network Open
– Ureteroscopy vs Shockwave Lithotripsy Results
– Percutaneous Nephrolithotomy vs Ureteroscopy Results
Preserving Kidney Function in Children with Chronic Kidney Disease (PRESERVE)
Study Design: Retrospective Observational
Funder: Patient-Centered Outcomes Research Institute® (PCORI®)
Principal Investigators: Christopher Forrest and Michelle Denberg, The Children’s Hospital of Philadelphia
Research questions:
- Which monitoring strategies and blood pressure medications best preserve kidney function in pediatric patients with chronic kidney disease (CKD)?
- What are the lived experiences of families and patients managing pediatric CKD?
Using PCORnet, the study team:
- Included 20,100 children (ages 1–17) with CKD seen at 15 healthcare institutions between Jan. 2009-Dec. 2021
- Engaged caregivers to assess lived experiences managing blood pressure
- Expanded the PCORnet® Common Data Model for pediatric and rare kidney disease research
Dissemination:
- Published findings on the comparative effectiveness of two treatments for high blood pressure in pediatric CKD in JAMA Pediatrics
- Published the study rationale, design, and methods in Kidney Medicine
- Published findings on using real-world electronic health record data to develop age-, sex-, and height-specific blood pressure percentiles for children in eBioMedicine
