Novel Cerebral Protection Technique During Right Transcarotid TAVR in Bicuspid Aortic Stenosis and Porcelain Aorta.

Periprocedural stroke related to transcatheter aortic valve replacement (TAVR) is associated with increased morbidity and mortality. Cerebral embolic protection using the Sentinel device (Claret Medical) has demonstrated reduced rates of stroke during TAVR. However, alternative access such as a transcarotid approach precludes the use of the Sentinel device. We report a case using cerebral embolic protection during a right transcarotid TAVR.

Decision Support System Requirements Definition for Human Extravehicular Activity Based on Cognitive Work Analysis.

The design and adoption of decision support systems within complex work domains is a challenge for cognitive systems engineering (CSE) practitioners, particularly at the onset of project development. This article presents an example of applying CSE techniques to derive design requirements compatible with traditional systems engineering to guide decision support system development. Specifically, it demonstrates the requirements derivation process based on cognitive work analysis for a subset of human spaceflight operations known as extravehicular activity. The results are presented in two phases. First, a work domain analysis revealed a comprehensive set of work functions and constraints that exist in the extravehicular activity work domain. Second, a control task analysis was performed on a subset of the work functions identified by the work domain analysis to articulate the translation of subject matter states of knowledge to high-level decision support system requirements. This work emphasizes an incremental requirements specification process as a critical component of CSE analyses to better situate CSE perspectives within the early phases of traditional systems engineering design.

Qualitative ergonomics/human factors research in health care: Current state and future directions.

The objective of this systematic review was to understand the current state of Ergonomics/Human Factors (E/HF) qualitative research in health care and to draw implications for future efforts. This systematic review identified 98 qualitative research papers published between January 2005 and August 2015 in the seven journals endorsed by the International Ergonomics Association with an impact factor over 1.0. The majority of the studies were conducted in hospitals and outpatient clinics, were focused on the work of formal health care professionals, and were classified as cognitive or organizational ergonomics. Interviews, focus groups, and observations were the most prevalent forms of data collection. Triangulation and data archiving were the dominant approaches to ensuring rigor. Few studies employed a formal approach to qualitative inquiry. Significant opportunities remain to enhance the use of qualitative research to advance systems thinking within health care.

Impact of electronic health record technology on the work and workflow of physicians in the intensive care unit.

OBJECTIVE: To assess the impact of EHR technology on the work and workflow of ICU physicians and compare time spent by ICU resident and attending physicians on various tasks before and after EHR implementation. DESIGN: EHR technology with electronic order management (CPOE, medication administration and pharmacy system) and physician documentation was implemented in October 2007. MEASUREMENT: We collected a total of 289 h of observation pre- and post-EHR implementation. We directly observed the work of residents in three ICUs (adult medical/surgical ICU, pediatric ICU and neonatal ICU) and attending physicians in one ICU (adult medical/surgical ICU). RESULTS: EHR implementation had an impact on the time distribution of tasks as well as the temporal patterns of tasks. After EHR implementation, both residents and attending physicians spent more of their time on clinical review and documentation (40% and 55% increases, respectively). EHR implementation also affected the frequency of switching between tasks, which increased for residents (from 117 to 154 tasks per hour) but decreased for attendings (from 138 to 106 tasks per hour), and the temporal flow of tasks, in particular around what tasks occurred before and after clinical review and documentation. No changes in the time spent in conversational tasks or the physical care of the patient were observed. CONCLUSIONS: The use of EHR technology has a major impact on ICU physician work (e.g., increased time spent on clinical review and documentation) and workflow (e.g., clinical review and documentation becoming the focal point of many other tasks). Further studies should evaluate the impact of changes in physician work on the quality of care provided.

Motivation and job satisfaction of Tele-ICU nurses.

INTRODUCTION: Although the first tele-ICU has been in existence for more than 12 years, little is known about the work of tele-ICU nurses. This study examines sources of motivation and satisfaction of tele-ICU nurses. METHODS: A total of 50 nurses in 5 tele-ICUs were interviewed about reasons for working as a tele-ICU nurse and sources of satisfaction and dissatisfaction in their job. RESULTS: Nurses have different motivations to work in the tele-ICU, including the challenges and opportunities for new learning that occur while interacting with clinicians in the tele-ICU and the various ICUs being monitored. Tele-ICU nurses also appreciate the opportunities for teamwork with tele-ICU physicians and nurses. The relationship and interactions with the ICUs is sometimes mentioned as a dissatisfier. Some nurses miss being physically at the bedside, as well as interacting with patients and families. CONCLUSION: Most tele-ICU nurses are satisfied with their job. They like the challenge in their work and the opportunity to learn. For some nurses, the transition from a bedside caregiver to an information manager can be difficult. Other nurses have found a balance by working part-time in the tele-ICU and part-time in the ICU.

MEASURING WORKLOAD OF ICU NURSES WITH A QUESTIONNAIRE SURVEY: THE NASA TASK LOAD INDEX (TLX).

High workload of nurses in Intensive Care Units (ICUs) has been identified as a major patient safety and worker stress problem. However, relative little attention has been dedicated to the measurement of workload in healthcare. The objectives of this study are to describe and examine several methods to measure workload of ICU nurses. We then focus on the measurement of ICU nurses' workload using a subjective rating instrument: the NASA TLX.We conducted secondary data analysis on data from two, multi-side, cross-sectional questionnaire studies to examine several instruments to measure ICU nurses' workload. The combined database contains the data from 757 ICU nurses in 8 hospitals and 21 ICUs.Results show that the different methods to measure workload of ICU nurses, such as patient-based and operator-based workload, are only moderately correlated, or not correlated at all. Results show further that among the operator-based instruments, the NASA TLX is the most reliable and valid questionnaire to measure workload and that NASA TLX can be used in a healthcare setting. Managers of hospitals and ICUs can benefit from the results of this research as it provides benchmark data on workload experienced by nurses in a variety of ICUs.
