Total hip replacement (THR) predictably relieves pain and restores mobility to people with hip arthritis and is considered one of the most significant medical advances of the 20th century. Large population and long-term studies1,2 show 85% or better revision-free 10-year survival. Because of the high ...

In Reply Adler and Yeh are to be commended for their culturally aware, close reading of our recent article1; we sincerely appreciate their thoughtfulness. Simply, patients self-identifying as racially white and ethnically “Hispanic or Latino” were categorized as Hispanic. This is not explicitly stated in the ...

Importance  Surgical disease is a global health priority, and improving surgical care requires local capacity building. Single-institution partnerships and surgical missions are logistically limited. The Alliance for Global Clinical Training (hereafter the Alliance) is a consortium of US surgical departments that aims to provide continuous educational support ...

Invited Commentary: The Conundrum of Training in Global Surgery; Mamta Swaroop, MD; Catherine deVries, MD
Invited Commentary 
Haile T. Debas, MD

The lack of accurate documentation of surgical experiences and outcomes in low- and middle-income countries is significant and constitutes a key barrier in making the case for resource allocation for global surgery to policymakers and global funders. The evidence that supports the importance and significance of surgery in ...

Invited Commentary 
Mamta Swaroop, MD; Catherine deVries, MD

Recent updates regarding the unmet surgical need indicate that 5 billion of the world’s 7 billion people lack access to safe and timely surgical care.1 One of the critically missing pieces is trained surgical staff, including surgeons, anesthesiologists, nurses, and biomedical engineers. The ecosystem of people and ...

Invited Commentary 
Thomas K. Varghese Jr, MD, MS

The performance of surgical procedures is inevitably associated with complications. The holy grail in assessing surgical quality is differentiating metrics that reflect the care a hospital and surgical team delivers (factors that can be improved) from those that are solely related to a patient’s medical comorbidities (factors often ...
