    Factors influencing Internet usage in older adults (65 years and above) living in rural and urban Sweden2015In: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811, Vol. 21, no 3, 237-249 p.Article in journal (Refereed)
    Abstract [en]

    Older adults living in rural and urban areas have shown to distinguish themselves in technology adoption; a clearer profile of their Internet use is important in order to provide better technological and health-care solutions. Older adults' Internet use was investigated across large to midsize cities and rural Sweden. The sample consisted of 7181 older adults ranging from 59 to 100 years old. Internet use was investigated with age, education, gender, household economy, cognition, living alone/or with someone and rural/urban living. Logistic regression was used. Those living in rural areas used the Internet less than their urban counterparts. Being younger and higher educated influenced Internet use; for older urban adults, these factors as well as living with someone and having good cognitive functioning were influential. Solutions are needed to avoid the exclusion of some older adults by a society that is today being shaped by the Internet.

    Detecting hospital-acquired infections: A document classification approach using support vector machines and gradient tree boosting2016In: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811Article in journal (Refereed)
    Abstract [en]

    Hospital-acquired infections pose a significant risk to patient health, while their surveillance is an additional workload for hospital staff. Our overall aim is to build a surveillance system that reliably detects all patient records that potentially include hospital-acquired infections. This is to reduce the burden of having the hospital staff manually check patient records. This study focuses on the application of text classification using support vector machines and gradient tree boosting to the problem. Support vector machines and gradient tree boosting have never been applied to the problem of detecting hospital-acquired infections in Swedish patient records, and according to our experiments, they lead to encouraging results. The best result is yielded by gradient tree boosting, at 93.7percent recall, 79.7percent precision and 85.7percent F1 score when using stemming. We can show that simple preprocessing techniques and parameter tuning can lead to high recall (which we aim for in screening patient records) with appropriate precision for this task.

    Introducing a process manager in healthcare: an experience report2005In: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811, Vol. 11, no 1, 45-61 p.Article in journal (Other academic)
    Abstract [en]

    To be efficient and patient focused, healthcare units need to be process oriented and integrated with the processes and IT systems of other healthcare units. A process manager facilitates integration of different systems by using graphical and executable process models. The process manager also communicates directly with healthcare personnel via desktop computers and mobile devices. This article reports on a Swedish project where a prototype system was developed and tested with several healthcare units. The experience shows several advantages and opportunities. For example, current information about patients can be transferred automatically between healthcare units; resource intensive manual tasks can be replaced with automated tasks; and long-term process monitoring and quality assessment can be enabled. However, introducing a process manager requires attention to issues of security, ethics and legality. Healthcare units may also show differences in security awareness and IT maturity, which could obstruct the introduction of a process manager.

    The coordination hub: Toward patient-centered and collaborative care processes2015In: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811, Vol. 21, no 4, 284-305 p.Article in journal (Refereed)
    Abstract [en]

    The organization and processes of today's health and social care are becoming ever more complex as a consequence of societal trends, including an aging population and an increased reliance on care at home. One aspect of the increased complexity is that a single patient may receive care from several care providers, which easily results in situations with potentially incoherent, uncoordinated, and interfering care processes. In order to describe and analyze such situations, the article introduces the notion of a process conglomeration. This is defined as a set of patient-care processes that all concern the same patient, that are overlapping in time, and that all are sharing the overall goal of improving or maintaining the health and social well-being of the patient. Problems and challenges of process conglomerations are investigated using coordination theory and models for continuous process improvement. In order to address the challenges, a solution is proposed in the form of a Coordination Hub, being an integrated software service that offers a number of information services for coordinating the activities of the processes in a process conglomeration.
