We do not maintain that only PCCM specialists should lead critical care units. All intensivists must have similar knowledge and skills and an interdisciplinary approach, regardless of their primary specialty, and achieving that requires rigorous training and certification. In the United States, the great majority of ICU physicians are subspecialists trained and certified in both pulmonary and critical care medicine.5 These physicians continue to fill a void left by diminishing numbers of anesthesiologists, surgeons, and internists who choose a practice consisting of only critical care. We believe that recognition by China of PCCM as a subspecialty, with a standardized curriculum, training path, and certification process, will dramatically increase the number of well-trained and skilled physicians urgently needed to care for the growing numbers of critically ill patients. We look forward to collaborating with our “pure” intensivist colleagues in advancing the science and practice of critical care medicine for the benefit of our patients.
