Abstract

A generic servomechanism (Fig. 1) is a useful analogy to explore sources of medical errors. In a servomechanism we distinguish the following elements: (1) an”integrator regulatory center” which exerts positive or negative controlling influences on (2) an”effector organ” whose output can be expressed in terms of (3) a”controlled variable” whose value at any point in time is measured by (4) a”detector” connected to (5) a”feedback network” which transmits measured values to the integrator center (6) a”set point of reference” and (7) information received from”other feedback loops.”
