Usage and usability of a national e-library for chemotherapy regimens: a mixed-method study (Preprint)

Abstract

Accurate information about chemotherapy drugs and regimens is needed to reduce chemotherapy errors. A national e-library, as a common knowledge source with standardized chemotherapy nomenclature and content, was developed. Since the information in the library is both complex and extensive it is central that the users can utilize the resource as intended.

The aim of this study was to evaluate the usage and usability of an extensive e-library for chemotherapy regimens developed to reduce medication errors and increase patient safety.

To obtain a comprehensive evaluation, a mixed-method was applied for a broad view of the usage, including a compilation of subjective views of the users (web survey, spontaneous user feedback, and qualitative interviews), analysis of statistics from the website, and an expert evaluation of the usability of the webpage.

Statistics from the website show an average of just over 2,500 visits and 870 unique visitors per month. Most visits took place Mondays to Fridays, but there were 5-10 visits per day on weekends. The web survey, with 292 answers, shows that the visitors were mainly physicians and nurses. Almost 80% (224/292) searched for regimens, 90% (264/292) found what they were looking for and were satisfied with their visit. The expert evaluation shows that the e-library follows many existing design principles giving some useful improvement suggestions. A total of 86 emails during 2020 giving user feedback were received, most of them from nurses. The main part (78%, 67/86) contained a question and the rest had discovered incorrectness mainly in some regimen. The interviews reveal that most hospitals use a computerized physician order entry system and they use the e-library in various ways, import XML files, transfer information, or as a reference. One hospital without a system uses the administration schedules from the library.

The user evaluation indicates that the e-library is used in the intended way and that the users can interact without problems. Users have different needs depending on their profession and their workplace and these can be supported. The combination of methods applied ensures that the design and content comply with the users’ needs and works as feedback for continuous design and learning. With a broad national usage, the e-library can become a source for organizational and national learning and a source for continuous improvement of cancer care in Sweden.
