Performance of a second generation pulmonary capnotracking system for continuous monitoring of cardiac output

Technologies for minimally-invasive cardiac output measurement in patients during surgery remain little used in routine practice. We tested a redeveloped system based on CO₂ elimination (VCO₂) by the lungs for use in ventilated patients, which can be seamlessly integrated into a modern anesthesia/monitoring platform, and provides automated, continuous breath-by-breath cardiac output monitoring. A prototype measurement system was constructed to measure VCO₂ and end-tidal CO₂ concentration with each breath. A baseline measurement of non-shunt cardiac output was made during a brief oscillating change in ventilator rate, according to the differential CO₂ Fick approach and repeated at 5–10 min intervals. Continuous breath-by-breath monitoring of cardiac output was performed between these intervals from measurement of VCO₂, using a derivation of the Fick equation applied to pulmonary CO₂ elimination and cardiac output displayed in real time. Measurements were compared with simultaneous measurements by thermodilution in 50 patients undergoing cardiac surgery or liver transplantation. Overall mean bias [sd] for agreement in cardiac output measurement was ??0.3 [1.1] L/min, percentage error?±?38.7%, intraclass correlation coefficient?=?0.91. Concordance in measurement of changes of at least 15% in cardiac output was 81.4%, with a mean angular bias of ??1.7°, and radial limits of agreement of ±?76.2° on polar plot analysis. The accuracy and precision compared favourably to other clinical techniques. The method is relatively seamless and automated and has potential for continuous, cardiac output monitoring in ventilated patients during anesthesia and critical care.     

Evaluation of a decision support app for nurses and case managers to facilitate aging in place of people with dementia. A randomized controlled laboratory experiment

Detecting practical problems of persons with dementia (PwD) experience at home, and advising them on solutions to facilitate aging in place are complex and challenging tasks for nurses and case managers. In this two group randomized, controlled laboratory experiment, the efficacy of a decision support application aiming to increase nurses' and case managers' confidence in clinical judgment and decision-making was tested. The participants (N?=?67) assessed a case of a PwD within the problem domains: self-reliance, safety and informal care, and provided suggestions for possible solutions. Participants used either their regular procedure with (intervention group) or without the App (control group) to conduct these tasks. No statistically significant difference was found on the primary outcome measure, the overall level of confidence. However, nurses and case managers highly recommended use of the App in practice. To explain these results, more research on the potential added value of the App is needed.     

Quality of Working Life Issues of Employees with a Chronic Physical Disease: A Systematic Review

Purpose To assess issues that contribute to the Quality of Working Life (QWL) of employees with a chronic physical disease. Methods A systematic literature search was conducted using the databases PubMed, PsycINFO and EMBASE. Experiences and perceptions during the working life of employees with a chronic physical disease were extracted and synthesized into issues that contributed to their QWL. We organized these synthesized QWL issues into higher order themes and categories with qualitative data analysis software. Results From a total of 4,044 articles identified by the search, 61 articles were included. Data extraction and data synthesis resulted in an overview of 73 QWL issues that were classified into 30 themes. The following five categories of themes were identified: (1) job characteristics with issues such as job flexibility and work-site access; (2) the social structure and environment containing issues about disclosure, discrimination, misunderstanding, and awareness by employers or colleagues; (3) organizational characteristics with issues such as requesting work accommodations; (4) individual work perceptions including issues about enjoyment and evaluating work or life priorities; and (5) effect of the disease and treatment including issues about cognitive and physical health and work ability. Conclusion This systematic review offers an extensive overview of issues that might contribute to the QWL of employees with a chronic physical disease. This overview may function as a starting point for occupational support, such as monitoring and evaluating the QWL of employees with a chronic physical disease during return-to-work and work continuation processes.     

Care planning for long‐term conditions – a concept mapping

Objective

This article focuses on approaches within clinical practice that seek to actively involve patients with long‐term conditions (LTCs) and how professionals may understand and implement them. Personalized care planning is one such approach, but its current lack of conceptual clarity might have impeded its widespread implementation to date. A variety of overlapping concepts coexist in the literature, which have the potential to impair both clinical and research agendas. The aim of this article is therefore to explore the meaning of the concept of care planning in relation to other overlapping concepts and how this translates into clinical practice implementation.

Methods

Searches were conducted in the Cochrane database for systematic reviews, CINHAL and MEDLINE. A staged approach to conducting the concept mapping was undertaken, by (i) an examination of the literature on care planning in LTCs; (ii) identification of related terms; (iii) locating reviews of those terms. Retrieved articles were subjected to a content analysis, which formed the basis of our concept maps. (iv) We then appraised these against knowledge and experience of the implementation of care planning in clinical practice.

Results and Conclusions

Thirteen articles were retrieved, in which the core importance of patient‐centredness, shared decision making and self‐management was highlighted. Literature searches on these terms retrieved a further 24 articles. Our concept mapping exercise shows that whilst there are common themes across the concepts, the differences between them reflect the context and intended outcomes within clinical practice. We argue that this clarification exercise will allow for further development of both research and clinical implementation agendas.
