An integrative review exploring the impact of Electronic Health Records (EHR) on the quality of nurse–patient interactions and communication
Aim.
To explore how nurses' use of electronic health records impacts on the quality of nurse–patient interactions and communication.
Design.
An integrative review.
Data sources.
MEDLINE®, CINAHL®, PscyINFO, PubMed, BNI and Cochrane Library databases were searched for papers published between January 2005 and April 2022.
Review methods.
Following a comprehensive search, the studies were appraised using a tool appropriate to the study design. Data were extracted from the studies that met the inclusion criteria relating to sample characteristics, methods and the strength of evidence. Included empirical studies had to examine interactions or communication between a nurse and patient while electronic health records were being used in any healthcare setting. Findings were synthesized using a thematic approach.
Results.
One thousand nine hundred and twenty articles were initially identified but only eight met the inclusion criteria of this review. Thematic analysis revealed four key themes, indicating that EHR: impedes on face-to-face communication, promotes task-orientated and formulaic communication and impacts on types of communication patterns.
Conclusion.
Research examining nurse–patient interactions and communication when nurses' use electronic health records is limited but evidence suggests that closed nurse–patient communications, reflecting a task-driven approach, were predominantly used when nurses used electronic health records, although some nurses were able to overcome logistical barriers and communicate more openly. Nurses' use of electronic health records impacts on the flow, nature and quality of communication between a nurse and patient.
Impact.
The move to electronic health records has taken place largely without consideration of the impact that this might have on nurse–patient interaction and communication. There is evidence of impact but also evidence of how this might be mitigated. Nurses must focus future research on examining the impact that these systems have, and to develop strategies and practice that continue to promote the importance of nurse–patient interactions and communication.

Bereaved caregivers’ experiences of end of life care for people with advanced heart failure: A narrative synthesis
Background. Heart Failure is a life-limiting condition with a poor and uniquely unpredictable prognosis. The aim of this review is to present and synthesise the current evidence around bereaved caregivers’ experiences of end of life care for people with Heart Failure.
Methods. A systematic review of the literature was conducted using four electronic databases (CINHAL, Medline, BND, PsycINFO). Data was analysed and presented using a narrative synthesis approach.
Results. Eight articles were included within this review. Themes included: Limited and inadequate communication around the condition (including prognosis, preparations for death and the aim of palliative care), the burden of caregiving, and the limited provision of services and formal support.
Conclusion. Bereaved caregivers experience unique and significant challenges when caring for someone dying from Heart Failure. However, further research is required to greater understand the experiences of bereaved caregivers of people with Heart Failure
Patients’ experiences of attending an adapted cardiac rehabilitation programme for heart failure in a day hospice
Background. Heart Failure is highly prevalent with poor outcomes yet only a small proportion of patients receive specialist palliative care services.
Aim. To explore if a programme focussing on support and symptom management of people with heart failure in a hospice environment would be acceptable and of benefit to patients. Methods: A pre/post intervention study design using mixed methods was used to evaluate the programme. The programme was delivered in two-hour time slots over a period of 8 weeks. Participants completed 3 questionnaires pre and post and were interviewed within one week of completion. The study was conducted between June 2014 and January 2015.
Findings. A response rate of 51.7% gave a final sample size of 12 patients. The questionnaire results showed a positive impact on participants’ well-being and views regarding the use of a hospice, but a desire for greater focus on emotional support. Four key themes emerged from inductive qualitative analysis: demystifying perceptions about hospice; positivity about well-being; learning together and consideration of end of life preparation.
Conclusion. This adapted programme provides a useful model for the increased integration of palliative care into the provisions for those living with advancing heart failure
Implementation of a web-based resilience enhancement training for nurses : pilot randomized controlled trial
Background:
Global workforce challenges faced by health care providers are linked to low levels of job satisfaction, recruitment, retention, and well-being, with detrimental impacts on patient care outcomes. Resilience-building programs can provide support for staff who endure highly stressful environments, enhance resilience, and support recruitment and retention, with web-based formats being key to increasing accessibility.
Objective:
We aimed to examine participants’ engagement with a newly developed Resilience Enhancement Online Training for Nurses (REsOluTioN), explore its acceptability, and compare levels of resilience and psychological well-being in nurses who completed REsOluTioN with those who did not.
Methods:
We carried out a pilot randomized trial (1:1), conducted at a single site (mental health and community trust in South England) between August 2021 and May 2022. Local research ethics approvals were obtained. Nurses were invited to participate and were randomly assigned to a waitlist group or REsOluTioN group. Training lasted for 4 weeks, consisting of prereading, web-based facilitated sessions, and mentorship support. We evaluated trial engagement, acceptability of training, and pre-post changes in resilience, measured by the Brief Resilience Scale, and psychological well-being, measured by the Warwick Edinburgh Mental Wellbeing Scale. Qualitative participant feedback was collected. Consolidated Standards of Reporting Trials 2010 extension guidelines for reporting pilot and feasibility trials were used.
Results:
Of 108 participants recruited, 93 completed the study. Participants’ mean age was 44 (SD 10.85) years. Most participants were female (n=95, 88.8%), White (n=95, 88.8%), and worked in community settings (n=91, 85.0%). Sixteen facilitated and 150 mentoring sessions took place. Most REsOluTioN program participants reported the sessions helped improve their resilience (n=24, 72.8%), self-confidence (n=24, 72.7%), ability to provide good patient care (n=25, 75.8%), relationships with colleagues (n=24, 72.7%), and communication skills (n=25, 75.8%). No statistically significant differences between training and control groups and time on well-being (F1,91=1.44, P=.23, partial η2=0.02) and resilience scores (F1,91=0.33, P=.57, partial η2=0.004) were revealed; however, there were positive trends toward improvement in both. Nurse participants engaged with the REsOluTioN program and found it acceptable. Most found web-based training and mentoring useful and enjoyed learning, reflection, networking, and participatory sessions.
Conclusions:
The REsOluTioN program was acceptable, engaging, perceived as useful, and nurses were keen for it to be implemented to optimize resilience, psychological health, communication, and workplace environments. The study has evidenced that it is acceptable to implement web-based resilience programs with similar design features within busy health care settings, indicating a need for similar programs to be carefully evaluated. Mentorship support may also be a key in optimizing resilience. Trial limitations include small sample size and reduced statistical power; a multicenter randomized controlled trial could test effectiveness of the training on a larger scale
Galaxy Zoo: the dependence of morphology and colour on environment
We analyse the relationships between galaxy morphology, colour, environment
and stellar mass using data for over 100,000 objects from Galaxy Zoo, the
largest sample of visually classified morphologies yet compiled. We
conclusively show that colour and morphology fractions are very different
functions of environment. Both are sensitive to stellar mass; however, at fixed
stellar mass, while colour is also highly sensitive to environment, morphology
displays much weaker environmental trends. Only a small part of both relations
can be attributed to variation in the stellar mass function with environment.
Galaxies with high stellar masses are mostly red, in all environments and
irrespective of their morphology. Low stellar-mass galaxies are mostly blue in
low-density environments, but mostly red in high-density environments, again
irrespective of their morphology. The colour-density relation is primarily
driven by variations in colour fractions at fixed morphology, in particular the
fraction of spiral galaxies that have red colours, and especially at low
stellar masses. We demonstrate that our red spirals primarily include galaxies
with true spiral morphology. We clearly show there is an environmental
dependence for colour beyond that for morphology. Before using the Galaxy Zoo
morphologies to produce the above results, we first quantify a luminosity-,
size- and redshift-dependent classification bias that affects this dataset, and
probably most other studies of galaxy population morphology. A correction for
this bias is derived and applied to produce a sample of galaxies with reliable
morphological type likelihoods, on which we base our analysis.Comment: 25 pages, 20 figures (+ 6 pages, 11 figures in appendices);

Normal Mouse Intestinal Epithelial Cells as a Model for the in vitro Invasion of Trichinella spiralis Infective Larvae
It has been known for many years that Trichinella spiralis initiates infection by penetrating the columnar epithelium of the small intestine; however, the mechanisms used by the parasite in the establishment of its intramulticellular niche in the intestine are unknown. Although the previous observations indicated that invasion also occurs in vitro when the infective larvae are inoculated onto cultures of intestinal epithelial cells (e.g., human colonic carcinoma cell line Caco-2, HCT-8), a normal readily manipulated in vitro model has not been established because of difficulties in the culture of primary intestinal epithelial cells (IECs). In this study, we described a normal intestinal epithelial model in which T. spiralis infective larvae were shown to invade the monolayers of normal mouse IECs in vitro. The IECs derived from intestinal crypts of fetal mouse small intestine had the ability to proliferate continuously and express specific cytokeratins as well as intestinal functional cell markers. Furthermore, they were susceptible to invasion by T. spiralis. When inoculated onto the IEC monolayer, infective larvae penetrated cells and migrated through them, leaving trails of damaged cells heavily loaded with T. spiralis larval excretory-secretory (ES) antigens which were recognized by rabbit immune sera on immunofluorescence test. The normal intestinal epithelial model of invasion mimicking the natural environment in vivo will help us to further investigate the process as well as the mechanisms by which T. spiralis establishes its intestinal niche
