A computer-based protocol system is a paradigm providing a set of tools which allow health care providers access to current guidelines which they can apply in practice. Studies have shown that protocols can aid in optimising patient care. There are two types of protocol systems: passive and active.
In a healthcare setting, a protocol, also called a medical guideline, is a set of instructions which describe a process to be followed to investigate a particular set of findings in a patient, or the method which should be followed to control a certain disease.
