PublicationText-based Healthcare Chatbots Supporting Patient and Health Professional Teams: Preliminary Results of a Randomized Controlled Trial on Childhood Obesity( 2017-08-27)
;Nißen, Marcia ;Shih, Chen-Hsuan Iris ;Rüegger, Dominik ;Künzler, Florian ;Barata, Filipe ;Büchter, Dirk ;Brogle, Björn ;Heldt, Katrin ;Gindrat, Pauline ;Farpour-Lambert, Nathaliel’Allemand, DagmarHealth professionals have limited resources and are not able to personally monitor and support patients in their everyday life. Against this background and due to the increasing number of self-service channels and digital health interventions, we investigate how text-based healthcare chatbots (THCB) can be designed to effectively support patients and health professionals in therapeutic settings beyond on-site consultations. We present an open source THCB system and how the THCP was designed for a childhood obesity intervention. Preliminary results with 15 patients indicate promising results with respect to intervention adherence (ca. 13.000 conversational turns over the course of 4 months or ca. 8 per day and patient), scalability of the THCB approach (ca. 99.5% of all conversational turns were THCB-driven) and over-average scores on perceived enjoyment and attachment bond between patient and THCB. Future work is discussed.Type: conference paper -
PublicationTowards Short-Term Detection of Job Strain in Knowledge Workers with a Minimal-Invasive Information System Service: Theoretical Foundation and Experimental Design(Association for Information Systems, 2015-05-25)
;Wahle, Fabian ;Haug, Severin ;Jenny, Gregor ;Bauer, Georg F.Early detection and tailored treatment of job strain is important because it negatively affects the health condition of employees, the performance of organizations, and the overall costs of the health care system likewise. Although there exist several self-report instruments for measuring job strain, one major limitation is the low frequency of measurements and, related to it, high-effort and high-costs associated with each wave of data collection. As a result and significant shortcoming, short-term epi-sodes of high job strain with serious negative outcomes cannot be identified reliably. The current research aims therefore to design, implement and evaluate a Job Strain Information System Service (JSISS) that continuously senses the degree of physiological job strain in knowledge workers solely based on mouse interactions. The following questions guide this research endeavour: (1) Which properties of an employee’s motor activity measured by mouse interactions are significantly related to the degree of physiological job strain? (2) Is physiological job strain related to self-reported psychological job strain? This research adopts the Job Demands-Resource model and the stress theory of van Gemmert and van Galen (1997) and proposes a lab experiment to answer the two research questions and thus, to examine the overall utility of the JSISS.Type: conference paper -
PublicationA Health Information System that Extends Healthcare Professional-Patient Communication(Association for Information Systems, 2014-06-09)
;Korak, Klaus ;Avital, Michel ;Leimeister, Jan MarcoSchultze, UlrikeCommunication between healthcare professionals and patients as part of the therapeutic process is often restricted to short, episodic face-to-face encounters with in healthcare institutions. The absence of a continuous communication process that extends the face-to-face encounter to include the therapeutic process outside the institution limits the support and guidance healthcare professionals can provide, and in turn negatively affects patients' adherence, health outcomes, and overall healthcare costs.This paper introduces the notion of interaction-templates that structure communication between healthcare professionals and patients along the entire therapeutic process.The presented health information system (HIS) prototype implements a follow-up and guidance process triggered by the face-to-face encounter, combining predefined interaction-templates and dialog functions enabling individual, situation-dependent communication. Analysis of data generated with the prototype will provide a better understanding of the structure, form, and content of communication in HIS that extend healthcare professional-patient communication.Type: conference paper -
PublicationEmerging Patterns of Communication in a Pharmacist- Patient Health Information System(Springer International Publishing, 2014-05-21)
;Korak, KlausTremblay, Monica ChiariniCommunication between healthcare professionals and patients is a major determinant of patients' satisfaction, patients' adherence, health outcomes, and ultimately of healthcare costs [1]. In most cases, however, personal communication between a healthcare professional and a patient is restricted to episodic face-to-face encounters. Once the face-to-face encounter comes to an end, structured communication ends. The absence of structured communication in time intervals between face-to-face encounters is a defining characteristic of current healthcare professional-patient interaction [2,3]. As a consequence, healthcare professionals lack the ability to guide patients outside the institutional space and to adjust supportive measures depending on particular situations and needs that arise during the therapeutic process.Type: conference paperVolume: LNCS 8463 -

PublicationTowards Design Principles for Pharmacist-Patient Health Information Systems(Springer, 2013-06-11)
;Korak, Klaus ;Brückner, David ;Vom Brocke, Jan ;Hekkala, Riitta ;Ram, SudhaRossi, MattiA significant drawback of communications between patients and health professionals is their restriction to face-to-face encounters within healthcare institutions. This limits the support health professionals can provide to ensure patient adherence, which is a significant contributor to therapeutic outcome and overall healthcare expenses. Pharmacist-patient health information systems (PPHIS) have the potential to address existing non-adherence behaviors by enabling pharmacist-patient communication over the time of therapy. Due to the lack of prior research, design principles for PPHIS are derived from the information-, motivation-, and strategy model [4] and feedback from pharmacists in 21 Swiss pharmacies. To demonstrate the feasibility of the design principles, we implement and preliminarily evaluate a PPHIS.Type: conference paperVolume: LNCS 7939Scopus© Citations 4 -
PublicationDesign and Evaluation of a Mobile Chat App for the Open Source Behavioral Health Intervention Platform MobileCoach(Springer International Publishing - Springer, 2017)
;Shih, Iris ;Rüegger, Dominik ;Künzler, Florian ;Barata, Filipe ;Büchter, Dirk ;Brogle, Björn ;Heldt, Katrin ;Gindrat, Pauline ;Farpour-Lambert, Nathalie ;l’Allemand, Dagmar ;Maedche, Alexander ;vom Brocke, JanHevner, AlanThe open source platform MobileCoach (mobile-coach.eu) has been used for various behavioral health interventions in the public health context. However, so far, MobileCoach is limited to text message-based interactions. That is, participants use error-prone and laborious text-input fields and have to bear the SMS costs. Moreover, MobileCoach does not provide a dedicated chat channel for individual requests beyond the processing capabilities of its chatbot. Intervention designers are also limited to text-based self-report data. In this paper, we thus present a mobile chat app with pre-defined answer options, a dedicated chat channel for patients and health professionals and sensor data integration for the MobileCoach platform. Results of a pretest (N = 11) and preliminary findings of a randomized controlled clinical trial (N = 14) with young patients, who participate in an intervention for the treatment of obesity, are promising with respect to the utility of the chat app.Type: book sectionIssue: 10243Scopus© Citations 54 -
