Abstrakt

When computerized physician order entry systems (CPOE) are introduced there is a general expectation that the system can reduce medical errors and make work flow more efficient. This study asks why potential security problems continue despite intentions in CPOE. The study show how the organisation focus on implementation and forget to analyse potential adverse drug effects, and how hidden elements has influence on work flow and security.
Linear models are selected as basis, but the linearity doesn’t reflect real life conditions. The article argue that diversity and local evolution influences how users use CPOE in practise, CPOE can’t determine users work flow, users act according to values, practical factors, existing routines etc. Physical elements, culture, routines and habits affect CPOE. Therefore it is necessary to continue to study details in CPOE used in daily work.
The conclusion is there is a need for more socio technical studies that can enlighten how CPOE work in medical practise and someone who has responsibility to secure focus on improving security and efficiency.
