Design of Pulsappen: A mobile healthcare application to make administrative work more efficient for caregivers

University essay from Lunds universitet/Ergonomi och aerosolteknologi

Abstract: Staff in hospital wards experience a number of issues related to administrative tasks. These problems include needing to document the same information in multiple systems, and difficulties in shift handovers between staff members. The existing product Pulstavlan, developed by Stretch Care AB, aims to solve these issues. However, as the product is stationary, it does not enable staff to bring the information it contains with them when providing bedside care to patients. This master's thesis describes a user-centered design process, in which a digital and interactive prototype of a mobile product compatible with Pulstavlan was designed. The aim of the product is to ease the administrative work load on caregivers, and to lay the ground for future design solutions within the same area. The design was based on a user study of hospital staff, including 15 interviews with a total of 18 users, and six observations of Pulstavlan in use. The user study resulted in a number of expressed needs of the hospital staff, and goals that the mobile product design needed to fulfill to meet the needs. These needs and goals were used to formulate twelve necessary functions of the application design. Four iterations of prototyping were done; two iterations of an analogue prototype and two iterations of a digital prototype. All iterations were evaluated by letting users complete test scenarios similar to tasks performed on hospital wards, while applying a think-aloud protocol. The final prototype was considered to have good usability by all test persons, who worked in healthcare and had experience of using Pulstavlan. This was indicated by their ability to successfully complete a majority of test scenarios and by the positive feedback given. It was also indicated by the System Usability Scale assessment 'good usability'. To achieve a design fully optimised for caregivers, additional iterations can be made to test the design. A greater number of the desirable functions expressed in the user interviews can also be implemented to improve the final prototype further. Finally, the number of people testing the prototypes could be increased.
