- Passive Landau cavities have been built, installed and taken into regular operation in the MAX II ring. The purpose of the Landau damping system is twofold: to decrease the energy spread of the beam induced by coupled bunch oscillations and to increase the Touschek life-time. The cavities are of the pillbox type operated at 1500 MHz, the third harmonic of the main RF. This paper describes the design, tuning and operational results of the cavities.

- A 3D-computer game was used as a training utility to promote motor relearning on a telemedicine platform in a laboratory setting. The subject suffered from a left arm paresis. He was evaluated before and after treatment with a specific hand function task, a standardized grip force measure test and an upper extremity task. Grip force, endurance and the movement pattern of the upper extremity improved after the treatment. The telemedicine platform allows the professional to record and evaluate progress. The findings implicate that training with Virtual Reality and Haptics can promote motor rehabilitation

Going Mobile With Diabetes Support : A Randomized Study of a Text Message–Based Personalized Behavioral Intervention for Type 2 Diabetes Self-Care

- Objective. Patients with type 2 diabetes often fail to achieve self-management goals. This study tested the impact on glycemic control of a two-way text messaging program that provided behavioral coaching, education, and testing reminders to enrolled individuals with type 2 diabetes in the context of a clinic-based quality improvement initiative. The secondary aim examined patient interaction and satisfaction with the program.Methods. Ninety-three adult patients with poorly controlled type 2 diabetes (A1C >8%) were recruited from 18 primary care clinics in three counties for a 6-month study. Patients were randomized by a computer to one of two arms. Patients in both groups continued with their usual care; patients assigned to the intervention arm also received from one to seven diabetes-related text messages per day depending on the choices they made at enrollment. At 90 and 180 days, A1C data were obtained from the electronic health record and analyzed to determine changes from baseline for both groups. An exit survey was used to assess satisfaction. Enrollment behavior and interaction data were pulled from a Web-based administrative portal maintained by the technology vendor.Results. Patients used the program in a variety of ways. Twenty-nine percent of program users demonstrated frequent engagement (texting responses at least three times per week) for a period of ≥90 days. Survey results indicate very high satisfaction with the program. Both groups’ average A1C decreased from baseline, possibly reflecting a broader quality improvement effort underway in participating clinics. At 90 and 180 days, there was no statistically significant difference between the intervention and control groups in terms of change in A1C (P >0.05).Conclusions. This study demonstrated a practical approach to implementing and monitoring a mobile health intervention for self-management support across a wide range of independent clinic practices.

Health in Hand: Putting mHealth Design in Context

Konferensbidrag (refereegranskat)abstract
- Wireless technologies, cloud computing and connectivity have enabled mobile services that extend the coverage of health services, resulting in a branch of eHealth now commonly referred to as mHealth. However, at least in Sweden, where the healthcare sector is heavily institutionalized and regulated, mHealth has so far mainly evolved in the form of applications for support of healthy life-style and self-management of chronic diseases, implemented outside of the firewalls of traditional healthcare delivery environments. In this paper we present an on-going Indo-Swedish research and development project in which we are putting mHealth design into context both from a patient's perspective and from the perspective of a healthcare team working within a professional healthcare organization. Our research approach is inspired by the Scandinavian tradition of Participatory Design of ICT and informed by studies of how to measure usability, user experience and impact of mHealth interventions. The involved research teams are multi-disciplinary, including researchers from engineering, computing and health sciences. The project includes, on the Swedish side, a partner from the public healthcare sector, three SME:s and an industrial partner who is currently providing Electronic Patient Record and other healthcare information system solutions and who is interested in developing mobile solutions for healthcare professionals. We are currently in the process of collaborative articulation and specification of problems, goals and requirements within the framework of the first Swedish case study of the project, focused on mobile support for patients with diabetes type 2 and their healthcare teams.

Transforming Healthcare Delivery : ICT Design for Self-Care of Type 2 Diabetes
- 2014
-
Konferensbidrag (refereegranskat)abstract
- In this position paper we present an on-going case study where the aim is to design and implement mobile technologies for self-care for patients with type 2 diabetes. The main issue we are addressing in this paper is how to bridge clinical and non-clinical settings when designing self-care technologies. Usability, User Experience and Participatory Design are central aspects of our research approach. For designing with and for patients in home settings and everyday life situations, this approach has so far not been problematic. However, when it comes to designing with and for user groups located within a large healthcare organization, in a highly institutionalized clinical setting, the situation is different. We have recently introduced the Health Usability Maturity Model (UMM) to our project partners as a potential tool for bringing usability and participa-tory design issues to the fore as strategic assets for transforming healthcare delivery with ICT.

A Modified User-Oriented Heuristic Evaluation of a Mobile Health System for Diabetes Self-management Support

Tidskriftsartikel (refereegranskat)abstract
- Mobile health platforms offer significant opportunities for improving diabetic self-care, but only if adequate usability exists. Expert evaluations such as heuristic evaluation can provide distinct usability information about systems. The purpose of this study was to complete a usability evaluation of a mobile health system for diabetes patients using a modified heuristic evaluation technique of (1) dual-domain experts (healthcare professionals, usability experts), (2) validated scenarios and user tasks related to patients' self-care, and (3) in-depth severity factor ratings. Experts identified 129 usability problems with 274 heuristic violations for the system. The categories Consistency and Standards dominated at 24.1% (n = 66), followed by Match Between System and Real World at 22.3% (n = 61). Average severity ratings across system views were 2.8 (of 4), with 9.3% (n = 12) rated as catastrophic and 53.5% (n = 69) as major. The large volume of violations with severe ratings indicated clear priorities for redesign. The modified heuristic approach allowed evaluators to identify unique and important issues, including ones related to self-management and patient safety. This article provides a template for one type of expert evaluation adding to the informaticists' toolbox when needing to conduct a fast, resource-efficient and user-oriented heuristic evaluation.

Tidskriftsartikel (refereegranskat)abstract
- Mobile health applications for diabetes are developed like never before and many patients use them for their personalized health needs. With increased use, an increased number of usability evaluations are performed to assure that the applications function as intended. In this review the goal was to determine what usability methods are currently used in the evaluation of mobile health applications for diabetes and how these are used.METHODS: A literature review was conducted to identify applicable studies in the databases ACM Digital Library, Cinahl and Pubmed between the years 2015 and 2020. After the inclusion and exclusion criteria were applied, 32 articles remained that were included in the final review.RESULTS: Most of the studies included one established usability engineering method such as an expert-based and/or user-based method or a validated questionnaire/instrument. Some also included a combination of these. Others used methods of their own design; commonly questionnaires and interviews either on their own or in combination.CONCLUSION: To achieve an adequate level of evidence and quality in the evaluation, it is important that at least one is an established usability engineering method or a validated instrument. This to assure and continue to build the evidence base in this area.
