Abstract
This paper presents a year-long study of our project, aiming at (1) understanding the work practices of clinical staff in trauma intensive care units (TICUs) at a trauma center, with respect to their usage of clinical data interface systems, and (2) developing and evaluating an intuitive and user-centered clinical data interface system for their TICU environments. Based on a long-term field study in an urban trauma center that involved observation-, interview-, and survey-based studies to understand our target users and their working environment, we designed and implemented MediSenseView as a working prototype. MediSenseView is a clinical-data interface system, which was developed through the identification of three core challenges of existing interface system use in a trauma care unit—device separation, usage inefficiency, and system immobility—from the perspectives of three staff groups in our target environment (i.e., doctors, clinical nurses and research nurses), and through an iterative design study. The results from our pilot deployment of MediSenseView and a user study performed with 28 trauma center staff members highlight their work efficiency and satisfaction with MediSenseView compared to existing clinical data interface systems in the hospital.
Highlights
From patients’ physiological signal data to lab test results, medical images and electronic medical records (EMRs) (All abbreviations used in this paper are explained in Table 5), today’s hospitals are overwhelmed with patient data [1, 2]
Through a half-year-long field study with a fully operating prototype connected to the realtime data available through the hospital’s database, we identified how clinical and research staff at the trauma center access and analyze patient data using the existing EMR system developed by Metanet DT [12], a local mid-sized software development firm, which connects to the Philips IntelliVue MX800 [13] patient monitoring device
Results and feedback from this study suggest that the satisfaction levels of trauma intensive care units (TICUs) staff are high and the users are satisfied with the user-centered interface that MediSenseView provides
Summary
From patients’ physiological signal data to lab test results, medical images and electronic medical records (EMRs) (All abbreviations used in this paper are explained in Table 5), today’s hospitals are overwhelmed with patient data [1, 2]. While trauma ICU protocols have dramatically improved over the years with the help of state-of-the-art monitoring devices, we believe that these devices were designed without enough consideration on the clinical protocols and real-world usability; especially for such a special environment as a trauma care unit Based on such observations, we designed MediSenseView, a user-centered system for interfacing clinical data. [Understanding the users and their work practices] We performed a series of interviews and surveys, along with a half-year-long observational study with members of an urban trauma center to identify the usage patterns of clinical data in a TICU, and compiled a comprehensive set of user requirements for designing an effective user interface for trauma care units. As a bedside monitoring device, INSMA provides real-time information for improved decision making via acquisition, parsing, and visualization modules
