Does the EPR support the discharge process? A study on physicians' use of clinical information systems during discharge of patients with coronary heart disease.

This study has been performed in order to categorise and measure usage of different information sources and types in a well defined stage of clinical work. The underlying motivation is to improve computer-supported presentation and retrieval of relevant information and to be able to evaluate the functionality of a future improved interface to the electronic patient record (EPR). By observing 52 discharge processes and categorising information types and sources, we have observed that the paper chart is used as a primary source of information about recent events and procedures, while the EPR is mostly used for retrieving background information and verification. Direct communication with other clinicians and the patient is also important during the discharge process. Results from an additional survey show that the physicians report greater use of the EPR than the result from the observational study. The study clearly indicates that there is a large potential for improved EPR systems that support the physicians in their work regarding discharge of patients, especially in the future planning part of the discharge.
