Abstract
Algorithms originated in mathematics and form the basis of computer science. They have applications across a wide range of fields including health care. Critical care units have embraced use of algorithms due to the need to make rapid decisions using a large and disparate array of information. Feeding algorithms used in critical care are also referred to as nutrition support protocols. Their use has been demonstrated to improve nutritional intake as well as improving primary outcomes such as mortality and length of stay.
Earlier forms of nutrition support protocols relate to feeding processes such as initiation of feeding, feeding mode, and feeding intolerance. Later, feeding algorithms have incorporated selection of enteral feed and target feeding rate. It is essential that these algorithms are updated in line with evidence-based guidelines. Increasing use of algorithms and computerization will improve the accuracy of data collection and interpretations made from emerging research.
