Percentage of weight loss as a predictor of surgical risk: from the time of Hiram Studley to today.
Hiram Studley's 1936 article of research was the first publication to present a connection between preoperative weight loss and adverse postoperative outcome. Almost 70 years later, weight loss remains one of the most prominently used tools to assess nutritional status and predict surgical risk. This paper provides an overview of surgical practices at the time of Dr Studley and demonstrates Studley's unique contributions to the field of nutrition support. The search for more accurate methods of preoperative nutrition assessment is traced to show how subsequent research continues to validate the use of weight loss in the assessment of surgical risk. New developments center on techniques of body composition assessment to quantify weight lost as functional weight and clarify the impact of malnutrition on operative outcome.
