We thank Dr. Santhosh and colleagues for their letter concerning our article.1 We agree that the diagnostic journey includes interactions both between and across teams, not just those within the patient’s team. In an article currently in press in Diagnosis, we examine how systems and cognitive factors interact during the process of diagnosis. Specifically, we reported on how communication between consultants can be both a barrier and facilitator to the diagnostic process.2 We found that the frequency, quality, and pace of communication between and across inpatient teams and specialists are essential to timely diagnoses. As diagnostic errors remain a costly and morbid issue in the hospital setting, efforts to improve communication are clearly needed.3
