Research & Publications

Research Summary

Dr. Orens’ research interests are focused on lung transplantation. He is particularly interested in lung transplant outcomes specifically assessing risk factors for the development of chronic allograft rejection and primary graft dysfunction and developing new treatment strategies for these problems. Dr. Orens is internationally recognized as an expert in the care and management of lung transplant recipients.  He was the first to discover the benefit of treating lung allograft dysfunction with the macrolide antibiotic Azithromycin which is now a standard of care in lung transplantation.  He was the first author of the 2006 International Guidelines for the Selection of Lung Transplant Candidates.  He currently participates in several lung transplant research consortia including the NIH-sponsored Lung Transplant Outcomes Group, the NIH Genomic Research Alliance for Transplant, and an NIH-sponsored Clinical Trials in Organ Transplant program.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
