A well-controlled, meticulous process has a far higher probability of
resulting in a high quality of medical care than improvisation and uns
tructured creativity. Algorithms display decision-making treatment pro
cesses and problem-solving strategies by giving clearly defined and fo
rmalized guidelines. The flow chart for decision-making follows the ye
s/no dichotomy of binary logic. The systematic ordering of decision po
ints and consequent actions is guided by medical priority and thus reg
ulates the time-frame and sequence of each single step in a logical ma
nner. With the help of clinical algorithms highly complex processes su
ch as the management of the severely injured patient can be translated
into a clearly structured, logical pathway. Clinical algorithms repre
sent scientifically recognized treatment rules, indicate a solution fo
r solving problems and help users to organize ideas and recognize conn
ections. They delineate a consistent and valid guideline, while allowi
ng deviations in proven exceptions. The use of algorithms allows a sys
tematic search for errors in the process of quality management. In eme
rgency situations they suggest a structured means of problem solving f
or the less experienced user. Algorithms are useful instruments in the
teaching of medical decisionmaking.
