Liver Function in the Pig

The assessment of function of the isolated perfused liver remains complex. Much of this problem relates to an inability to compare function in vitro with that in vivo, because of a lack of knowledge of hepatic blood flow. This article documents measurement of total hepatic and portal blood flow in vivo in pigs, by means of the dye clearance method. The effects of starvation, glucose administration and anaesthesia are noted. Although these techniques are simple and may be performed in the awake animal, there are wide variations in values which would necessitate individual flow readings being obtained for any comparative study.S.

The effect of volunteers’ care and support on the health outcomes of older adults in acute care: A systematic scoping review

Aim: To examine the available evidence on the effects of care and support provided by volunteers on the health outcomes of older adults in acute care services. Background: Acute hospital inpatient populations are becoming older, and this presents the potential for poorer health outcomes. Factors such as chronic health conditions, polypharmacy and cognitive and functional decline are associated with increased risk of health care‐related harm, such as falls, delirium and poor nutrition. To minimise the risk of health care‐related harm, volunteer programmes to support patient care have been established in many hospitals worldwide. Design: A systematic scoping review. Methods: The review followed the PRISMA Extension for Scoping Reviews (PRISMA‐ScR) (File S1). Nine databases were searched (CINAHL, MEDLINE, EMBASE, Cochrane, Scopus, Web of Science, PubMed, ScienceDirect and JBI) using the following key terms: ‘hospital’, ‘volunteer’, ‘sitter’, ‘acute care’, ‘older adults’, ‘confusion’, ‘dementia’ and ‘frail’. The search was limited to papers written in English and published from 2002–2017. Inclusion criteria were studies involving the use of hospital volunteers in the care or support of older adult patients aged ≥ 65 years, or ≥ 50 years for Indigenous peoples, with chronic health conditions, cognitive impairment and/or physical decline or frailty, within the acute inpatient settings. Results: Of the 199 articles identified, 17 articles that met the inclusion criteria were critically appraised for quality, and 12 articles were included in the final review. Conclusions: There is evidence that the provision of volunteer care and support with eating and drinking, mobilising and therapeutic activities can impact positively upon patient health outcomes related to nutrition, falls and delirium. Further robust research is needed to determine the impact of volunteers in acute care and the specific care activities that can contribute to the best outcomes for older adults. Relevance to clinical practice: Volunteers can play a valuable role in supporting care delivery by nurses and other health professionals in acute care services, and their contribution can improve health outcomes for older adults in this setting

Self-Esteem Assessment of Adolescents Involved in Horsemanship Activities

The study reported here was designed to determine if participation in horsemanship activities is associated with change in self-esteem and other developmental competencies. The study examined 122 adolescents, aged 12-18 years, who participated in the Florida 4-H Horsemanship School during summer 2005. The results found a small but significant change in self-esteem after the adolescents participated in the 6-day residential horsemanship program. It is important to consider the findings of the study when designing a horsemanship school curriculum for adolescents. Equine activities also may provide beneficial results to youth, including increased self-esteem, physical exercise, and positive youth development

Factors associated with risk of falling among younger inpatients in a mental health setting—A systematic review

Aim: To synthesise evidence related to risk factors of falls among younger mental health inpatients age ≤ 65 years old. Background: Hospitalised patients with mental illness are at increased risk of falling. Specific risk factors for falls for younger inpatients are poorly understood. Design: Systematic review. Methods: Medline, CINAHL, APA PsycINFO, Scopus and Web of Science were searched for studies published in English till December 2022. The review followed the 2020 PRISMA checklist. Odds ratios and P values of significant risk fall factors and the frequency of factors related to circumstances of falls were extracted. Results: Nine studies were included and 95 risk factors, across seven categories were extracted. These categories included socio-demographic, fall-related factors, functional status, health and mental status, psychiatric diagnosis and assessment, medication, and staff related factors. Factors related to medication, health and mental status are most reported. Majority of the patients sustained minor or no injury from the fall and circumstances of fall vary across studies. Conclusion: Factors strongly associated with risk of falls were dizziness, use of psychotropics and antihypertensive drugs. A meta-analysis of risk factors was not possible due to different dependent variables studied, controlled confounding variables and control groups used. Relevance to clinical practice: Fall prevention is relevant to all patients in mental health settings. Approaches to fall risk assessment and management need to be better tailored to younger mental health patients in the psychiatric setting. Patient and public contribution: Patient or public contribution was not possible because of the study design

Choice architecture modifies fruit and vegetable purchasing in a university campus grocery store : time series modelling of a natural experiment

Background In developed countries, adolescent and young adult diets have been found to be nutritionally poor. The aim of this study was to examine whether a choice architecture intervention, re-arrangement of produce within a grocery store to increase the accessibility of fruit and vegetables, affected purchasing behaviour on a university campus. Methods A database of daily sales data from January 2012 to July 2017 was obtained from a campus grocery store. Two changes to the layout were made during this time period. In January 2015, fruit and vegetables were moved from the back of the store, furthest from the entrance, to the aisle closest to the entrance and an entrance-facing display increasing their accessibility. In April 2016, the entrance-facing display of fruit and vegetables was replaced with a chiller cabinet so that fruit and vegetables remained more accessible than during the baseline period, but less accessible than in the period immediately previously. A retrospective interrupted time series analysis using dynamic regression was used to model the data and to examine the effect of the store re-arrangements on purchasing. All analyses were carried out both for sales-by-quantity and for sales-by-money. Results The first shop re-arrangement which made fruit and vegetables more prominent, increased the percentage of total sales that were fruit and vegetables, when analysed by either items purchased or money spent. The second rearrangement also had a positive effect on the percentage of total sales that were fruit and vegetables compared to baseline, however this was not significant at the 5% level. Over the five year period, the percentage of sales that were fruit and vegetables declined both in terms of items purchased, and money spent. Conclusions Increasing accessibility of fruit and vegetables in a grocery store is a feasible way to improve the diet of students in tertiary education. There is evidence of declining fruit and vegetable consumption among the studied population, which should be further investigated

Nursing student experiences of death and dying during a palliative care clinical placement: Teaching and learning implications

The Building Capacity in Palliative Care Clinical Training project commenced in 2012 and is providing a dedicated palliative care clinical learning experience for nursing and medical students as part of preparation for palliative care practice in future workplaces. Many students fear death on a clinical placement. This paper reports on a pilot study as part the broader project evaluation that examined nursing students’ experiences of death and how the project driven teaching and learning supported students’ learning experiences

Emergencies within hospital wards: An observational study of the non-technical skills of medical emergency teams

Background Medical emergency teams are essential in responding to acute deterioration of patients in hospitals, requiring both clinical and non-technical skills. This study aims to assess the non-technical skills of medical emergency teams during hospital ward emergencies and explore team members perceptions and experiences of the use non-technical skills during medical emergencies. Methods A multi-methods study was conducted in two phases. During phase one observation and assessment of non-technical skills used in medical emergencies using the Team Emergency Assessment Measure (TEAM™) was conducted; and in the phase two in-depth interviews were undertaken with medical emergency team members. Results Based on 20 observations, mean TEAM™ ratings for non-technical skill domains were: ‘leadership’ 5.0 out of 8 (±2.0); ‘teamwork’ 21.6 out of 28 (±3.6); and ‘task management’ 6.5 out of 8 (±1.4). The mean ‘global’ score was 7.5 out of 10 (±1.5). The qualitative findings identified three areas, ‘individual’, ‘team’ and ‘other’ contributing factors, which impacted upon the non-technical skills of medical emergency teams. Conclusion Non-technical skills of hospital medical emergency teams differ, and the impact of the skill mix on resuscitation outcomes was recognised by team members. These findings emphasize the importance non-technical skills in resuscitation training and well-developed processes for medical emergency teams

Exploring orthopaedic patients’ experiences of hospital discharge: Implications for nursing care

Background Nurses play a key role in providing discharge education. With the increased demand for orthopaedic surgery and subsequent fast‐track surgical programmes resulting in reduction in hospital length of stay, obtaining patient feedback about discharge is important to inform nursing practice of discharge. Aim To explore patients’ experiences of discharge from hospital following orthopaedic surgery. Methods A descriptive qualitative study was undertaken with a sample of 34 patients discharged following orthopaedic surgery at a private acute Australian hospital. Individual semistructured telephone interviews were conducted and analysed using inductive thematic analysis. Findings From the analysis, patient experiences have been described in three themes: (1) experiences of hospital discharge, (2) perceptions of discharge information, and (3) limitations of discharge information. Although participants reported being informed when discharged from hospital, more information about medication management, constipation, and wound care would have better supported their recovery to assist in their self-care. Discussion Discharge experiences and perceptions varied between participants, highlighting the importance of nurses and other health professionals, in providing discharge information to meet individual patient needs. This included improved communication, information about the discharge process, management of medication, wound, and prevention of constipation as part of recovery. Conclusion Patient feedback has highlighted that nurses need to provide more tailored discharge information for orthopaedic patients to support recovery to prevent postdischarge problems and hospital readmission

An examination of students’ perceptions of their interprofessional placements in residential aged care

It is essential that health professionals are trained to provide optimal care for our ageing population. Key to this is a positive attitude to older adults along with the ability to work in teams and provide interprofessional care. There is limited evidence on the impact an interprofessional education (IPE) placement in a residential aged care facility (RACF) has on students. In 2015 in Western Australia, 51 students (30 % male, median age 23 years), from seven professions, undertook a placement between 2 and 13 weeks in length at 1 RACF. Pre- and post-placement measurements of attitudes to the elderly were collected using the Ageing Semantic Differential (ASD) questionnaire and level of readiness for interprofessional learning with the Readiness for Interprofessional Learning Scale (RIPLS). A total of 47 students completed matched ASD and RIPLS surveys. The mean total score on the ASD survey decreased significantly from pre- to post-placement from 116.0 to 108.9 (p = 0.033), indicating attitudes became increasingly positive towards older adults. Significant differences post-placement were seen indicating better readiness for interprofessional learning, for two out of four subscales on the RIPLS, namely “teamwork & collaboration” (42.1 – 44.0; (p = 0.000)) and “positive professional identity” (18.2 – 19.3 (p = 0.001)). The degree of change is similar to findings from other settings. The results support IPE-focussed student placements within RACF positively influence student’s attitudes towards the older adult as well as increase student’s readiness for interprofessional learning, confirming RACF are valuable places for training health professional

Clinical staff perceptions on the quality of end-of-life care in an Australian acute private hospital: A cross-sectional survey

Objective: To explore the perceptions of clinical staff on the quality of end-of-life care in an acute private hospital. Methods: A descriptive cross-sectional study with a convenience sample of clinical staff in an acute private hospital were surveyed using a validated end-of-life survey. Data from the surveys were analysed using descriptive statistics for quantitative responses and inductive content analysis for the open-ended responses. Results: Overall, 133 staff completed the survey. Of these, 107 had cared for a dying patient in the hospital. In total, 87.6% of participants felt confident in their ability to recognise a dying patient and 66.7% felt confident in their ability to talk to the patient and family. Almost one-third had not received specific training in the area. Conclusions: Hospitals need to take the lead in ensuring end-of-life care processes are embedded across clinical areas. This includes providing staff with end-of-life care education and support in the delivery of end-of-life care. These strategies will facilitate safe and quality end-of-life care, including better collaboration between patients, families and staff
