User interpretations of future information system use: a snapshot with technological frames.

Integrated information systems for managing patient data transform the nature of hospital work to the extent that the work practices, the responsibilities, even the professional identities are likely to undergo major changes. Therefore, during the organizational implementation of the IS, attention should be paid to the future users and how they understand and see what is going on. Here the focus is on these interpretation processes, analyzed as technological frames. That is, people develop different assumptions, expectations and knowledge concerning new technology. During this sense-making process they build their idea of that technology, its technological frame. We analyzed the pre-implementation frames that could be discerned in 24 interviews of hospital personnel. Main influences on the frames in this case were the work role in the organization, knowledge about the new system, and attitudes toward the old systems. The social context appeared to have a significant influence in the users' interpretation processes and the frames seemed to be congruent within one group. So far, the incongruence between groups appeared to have caused no major problems for the implementation.

Theoretical considerations of ethics in text mining of nursing documents.

This paper discusses theoretical considerations of ethics in building and using a text mining application in nursing documentation. Nursing documentation is based on the process of gathering information from the patient, setting goals for care, documenting nursing interventions and evaluating delivered nursing care. Privacy-sensitive health care documentation brings specific ethical concerns and difficulties that one needs to be aware of and conform to when developing and using text mining tools in electronic patient records. We discuss how patient confidentiality can be ensured in this domain and how text mining might support nurses to give better and more efficient care for their patients. Our conclusion is that text mining of nursing documents holds the promise of great benefits when the potential risks are taken into consideration.

Towards automated classification of intensive care nursing narratives.

Nursing narratives are an important part of patient documentation, but the possibilities to utilize them in the direct care process are limited due to the lack of proper tools. One solution to facilitate the utilization of narrative data could be to classify them according to their content. In this paper, we addressed two issues related to designing an automated classifier: domain experts' agreement on the content of the classes into which the data are to be classified, and the ability of the machine-learning algorithm to perform the classification on an acceptable level. The data we used were a set of Finnish intensive care nursing narratives. By using Cohen's kappa, we assessed the agreement of three nurses on the content of the classes Breathing, Blood Circulation and Pain, and by using the area under ROC curve (AUC), we measured the ability of the Least Squares Support Vector Machine (LS-SVM) algorithm to learn the classification patterns of the nurses. On average, the values of kappa were around 0.8. The agreement was highest in the class Blood Circulation, and lowest in the class Breathing. The LS-SVM algorithm was able to learn the classification patterns of the three nurses on an acceptable level; the values of AUC were generally around 0.85. Our results indicate that one way to develop electronic patient records could be tools that handle the free text in nursing documentation.
