User-centered visual analysis using a hybrid reasoning architecture for intensive care units
One problem pertaining to Intensive Care Unit information systems is that, in some cases, a very dense display of data can result. To ensure the overview and readability of the increasing volumes of data, some special features are required (e.g., data prioritization, clustering, and selection mechanisms) with the application of analytical methods (e.g., temporal data abstraction, principal component analysis, and detection of events). This paper addresses the problem of improving the integration of the visual and analytical methods applied to medical monitoring systems. We present a knowledge- and machine learning-based approach to support the knowledge discovery process with appropriate analytical and visual methods. Its potential benefit to the development of user interfaces for intelligent monitors that can assist with the detection and explanation of new, potentially threatening medical events. The proposed hybrid reasoning architecture provides an interactive graphical user interface to adjust the parameters of the analytical methods based on the users' task at hand. The action sequences performed on the graphical user interface by the user are consolidated in a dynamic knowledge base with specific hybrid reasoning that integrates symbolic and connectionist approaches. These sequences of expert knowledge acquisition can be very efficient for making easier knowledge emergence during a similar experience and positively impact the monitoring of critical situations. The provided graphical user interface incorporating a user-centered visual analysis is exploited to facilitate the natural and effective representation of clinical information for patient care
Understanding safety-critical interactions with a home medical device through Distributed Cognition
As healthcare shifts from the hospital to the home, it is becoming increasingly important to understand how patients interact with home medical devices, to inform the safe and patient-friendly design of these devices. Distributed Cognition (DCog) has been a useful theoretical framework for understanding situated interactions in the healthcare domain. However, it has not previously been applied to study interactions with home medical devices. In this study, DCog was applied to understand renal patientsâ interactions with Home Hemodialysis Technology (HHT), as an example of a home medical device. Data was gathered through ethnographic observations and interviews with 19 renal patients and interviews with seven professionals. Data was analyzed through the principles summarized in the Distributed Cognition for Teamwork methodology. In this paper we focus on the analysis of system activities, information flows, social structures, physical layouts, and artefacts. By explicitly considering different ways in which cognitive processes are distributed, the DCog approach helped to understand patientsâ interaction strategies, and pointed to design opportunities that could improve patientsâ experiences of using HHT. The findings highlight the need to design HHT taking into consideration likely scenarios of use in the home and of the broader home context. A setting such as home hemodialysis has the characteristics of a complex and safety-critical socio-technical system, and a DCog approach effectively helps to understand how safety is achieved or compromised in such a system

The Patient as a construction and a non-participant member of a change-process.
The contribution of this paper is a discussion about how the patient as a phenomenon is constructed and used by employees for different purposes, enabling and inhibiting change. The results are based on a three year case study in which data has been collected with interviews and observations. They have then been analyzed and interpreted within a framework consisting of theories about thinking collectives, structuration, information and knowledge management. The findings indicate that âthe patientâ has implications for how project management is conducted and a patient record upgraded at the anesthesia and intensive care unit of a hospital.the patient; anesthesia information management; constructionism; thinking collectives; knowledge management; structuration.

The organizational implications of medical imaging in the context of Malaysian hospitals
This research investigated the implementation and use of medical imaging in the
context of Malaysian hospitals. In this report medical imaging refers to PACS,
RIS/HIS and imaging modalities which are linked through a computer network. The
study examined how the internal context of a hospital and its external context
together influenced the implementation of medical imaging, and how this in turn
shaped organizational roles and relationships within the hospital itself. It further
investigated how the implementation of the technology in one hospital affected its
implementation in another hospital. The research used systems theory as the
theoretical framework for the study. Methodologically, the study used a case-based
approach and multiple methods to obtain data. The case studies included two
hospital-based radiology departments in Malaysia.
The outcomes of the research suggest that the implementation of medical imaging in
community hospitals is shaped by the external context particularly the role played by
the Ministry of Health. Furthermore, influences from both the internal and external
contexts have a substantial impact on the process of implementing medical imaging
and the extent of the benefits that the organization can gain. In the context of roles
and social relationships, the findings revealed that the routine use of medical
imaging has substantially affected radiographersâ roles, and the social relationships
between non clinical personnel and clinicians. This study found no change in the
relationship between radiographers and radiologists. Finally, the approaches to
implementation taken in the hospitals studied were found to influence those taken by
other hospitals.
Overall, this study makes three important contributions. Firstly, it extends Barleyâs
(1986, 1990) research by explicitly demonstrating that the organizationâs internal and
external contexts together shape the implementation and use of technology, that the
processes of implementing and using technology impact upon roles, relationships
and networks and that a role-based approach alone is inadequate to examine the
outcomes of deploying an advanced technology. Secondly, this study contends that
scalability of technology in the context of developing countries is not necessarily
linear. Finally, this study offers practical contributions that can benefit healthcare
organizations in Malaysia

Comparison of family centered care with family integrated care and mobile technology (mFICare) on preterm infant and family outcomes: a multi-site quasi-experimental clinical trial protocol.
BackgroundFamily Centered Care (FCC) has been widely adopted as the framework for caring for infants in the Neonatal Intensive Care Unit (NICU) but it is not uniformly defined or practiced, making it difficult to determine impact. Previous studies have shown that implementing the Family Integrated Care (FICare) intervention program for preterm infants in the NICU setting leads to significant improvements in infant and family outcomes. Further research is warranted to determine feasibility, acceptability and differential impact of FICare in the US context. The addition of a mobile application (app) may be effective in providing supplemental support for parent participation in the FICare program and provide detailed data on program component uptake and outcomes.MethodsThis exploratory multi-site quasi-experimental study will compare usual FCC with mobile enhanced FICare (mFICare) on growth and clinical outcomes of preterm infants born at or before 33âweeks gestational age, as well as the stress, competence and self-efficacy of their parents. The feasibility and acceptability of using mobile technology to gather data about parent involvement in the care of preterm infants receiving FCC or mFICare as well as of the mFICare intervention will be evaluated (Aim 1). The effect sizes for infant growth (primary outcome) and for secondary infant and parent outcomes at NICU discharge and three months after discharge will be estimated (Aim 2).DiscussionThis study will provide new data about the implementation of FICare in the US context within various hospital settings and identify important barriers, facilitators and key processes that may contribute to the effectiveness of FICare. It will also offer insights to clinicians on the feasibility of a new mobile application to support parent-focused research and promote integration of parents into the NICU care team in US hospital settings.Trial registrationClinicalTrials.gov, ID NCT03418870.

Bearing witness and being bounded; the experiences of nurses in adult critical care in relation to the survivorship needs of patients and families
Aim: To discern and understand the responses of nurses to the survivorship needs of patients and family members in adult critical care units.
Background: The critical care environment is a demanding place of work which may limit nurses to immediacy of care, such is the proximity to death and the pressure of work.
Design: A constructivist grounded theory approach with constant comparative analysis.
Methods: As part of a wider study and following ethical approval, eleven critical care nurses working within a general adult critical care unit were interviewed with respect to their experiences in meeting the psychosocial needs of patients and family members. Through the process of constant comparative analysis an overarching selective code was constructed. EQUATOR guidelines for qualitative research (COREQ) applied.
Results: The data illuminated a path of developing expertise permitting integration of physical, psychological and family care with technology and humanity. Gaining such proficiency is demanding and the data presented reveals the challenges that nurses experience along the way.
Conclusion: The study confirms that working within a critical care environment is an emotionally charged challenge and may incur an emotional cost. Nurses can find themselves bounded by the walls of the critical care unit and experience personal and professional conflicts in their role. Nurses bear witness to the early stages of the survivorship trajectory but are limited in their support of ongoing needs.
Relevance to Clinical Practice: Critical care nurses can experience personal and professional conflicts when caring for both patients and families. This can lead to moral distress and may contribute to compassion fatigue. Critical care nurses appear bounded to the delivery of physiological and technical care, in the moment, as demanded by the patient's acuity. Consequentially this limits nursesâ ability to support the onward survivorship trajectory. Increased pressure and demands on critical care beds has contributed further to occupational stress in this care setting
