What's new on defining diarrhea in tube-feeding studies?

Nurses who are involved in studies of tube feeding tolerance or who review the literature on this topic are confronted with a myriad of definitions and methods of reporting diarrhea. In a 1992 study, the authors reported that these definition differences influenced results. In a review of the current literature, they determined that little progress had been made toward standardizing definitions and reports of diarrhea in studies of tube feeding.
