"For them and for me": a qualitative exploration of peer befrienders' experiences supporting people with aphasia in the SUPERB feasibility trial.

PURPOSE: Peer-befriending, where support is offered by someone with shared lived experience, is an intervention that may facilitate successful adjustment in people experiencing post-stroke aphasia. This paper explores the experiences of the peer-befrienders. MATERIALS AND METHODS: People with aphasia were recruited as peer-befrienders within the SUPERB trial investigating befriending for people with post-stroke aphasia. The intervention comprised six visits over three months. Peer-befrienders were matched with at least one befriendee and received training and ongoing supervision. They were invited to participate in in-depth interviews which were analysed using framework analysis. RESULTS: All 10 befrienders participated in interviews, reporting on 19 matches. Seven main themes emerged: content of the sessions; befriender-befriendee relationship; negotiating the visits; handling boundaries and endings; positive impact of the befriending for befrienders and befriendees; and beliefs about the nature and value of peer support. While befrienders described challenges, such as negotiating journeys and witnessing distress, the role was perceived as a "secure challenge" due to the support and training received. CONCLUSIONS: Befrienders perceived the role as enjoyable and rewarding, and felt they were making a positive difference. They were unanimous in believing that people with aphasia can offer unique and valuable support to others with aphasia. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02947776, registered 28th October 2016.Implications for rehabilitationPeople with lived experience of stroke and aphasia were able to offer emotional and social peer support to others with aphasia within the SUPERB trial.Although there were challenges, peer befrienders perceived the role as rewarding and satisfying.Peer befrienders valued the training and ongoing supervision and support they received to deliver the intervention.It is recommended that rehabilitation professionals considering offering peer-befriending schemes provide training and ongoing supervision to support peer-befrienders fulfil their role, as well as practical support with, e.g., arranging visits.

"Loneliness can also kill:" a qualitative exploration of outcomes and experiences of the SUPERB peer-befriending scheme for people with aphasia and their significant others.

PURPOSE: People with aphasia post-stroke are at risk for depression and social isolation. Peer-befriending from someone with similar experiences may promote wellbeing and provide support. This paper explored the views of people with aphasia and their significant others about peer-befriending. MATERIALS AND METHODS: We conducted a qualitative study within a feasibility trial (SUPERB) on peer-befriending for people with post-stroke aphasia and low levels of distress. Of the 28 participants randomised to the intervention, semi-structured in-depth interviews were conducted with 10 purposively selected people with aphasia (at both 4- and 10-months post-randomisation) and five of their significant others (at 4-months). Interviews were analysed using Framework Analysis. RESULTS: Participants and their significant others were positive about peer-befriending and identified factors which influenced their experience: the befrienders' personal experience of stroke and aphasia, their character traits and the resulting rapport these created, the conversation topics they discussed and settings they met in, and the logistics of befriending, including planning visits and negotiating their end. Interviewees also made evaluative comments about the befriending scheme. CONCLUSION: Peer-befriending was an acceptable intervention. Benefits for emotional wellbeing and companionship were reported. The shared experience in the befriending relationship was highly valued.Implications for RehabilitationThe lived experience of stroke and aphasia of befrienders was highly valued by people with aphasia receiving peer-befriending.Training, regular supervision, and support for befrienders with practicalities such as organising visits ensured the befriending scheme was perceived as straightforward and acceptable by befriendees.Those receiving peer-befriending would recommend it to others; they found it beneficial, especially in terms of emotional wellbeing and companionship.

Complete Stokes vector analysis with a compact, portable rotating waveplate polarimeter.

Accurate calibration of polarization-dependent optical elements is often necessary in optics experiments. A versatile polarimeter device to measure the polarization state of light is a valuable tool in these experiments. Here, we report a rotating waveplate-based polarimeter capable of complete Stokes vector analysis of collimated light. Calibration of the device allows accurate measurements over a range of wavelengths, with a bandwidth of >30 nm in this implementation. A photo-interrupter trigger system supplies the phase information necessary for full determination of the Stokes vector. An Arduino microcontroller performs rapid analysis and displays the results on a liquid crystal display. The Arduino can also be interfaced with a computer to store time series of Stokes vectors. The optical measurement apparatus of the polarimeter is compact and can be placed anywhere on an optical table on a single standard post. The components to construct the device are only a fraction of the cost of commercially available devices, while the accuracy and precision of the measurements are of the same order of magnitude.

Is knowledge and practice safer in England after the release of national guidance on the resuscitation of patients in mental health and learning disabilities?

ACCESSIBLE SUMMARY: This paper reports on the issue of resuscitation in mental health inpatient environments. It reviews the literature on national standards and best practice when emergency situations arise in mental health settings. The discussion on the best practice literature takes place alongside the reporting of a national evaluation of how National Patient Safety Agency improvement guidelines for the provision for life support, and resuscitation for mental health service users was effectively implemented across health-care providers in England. Methods used to establish the effective use of the guidelines include feedback from clinical staff and staff responsible for the implementation of the new national standards for resuscitation. Serious incident data were also compared prior to the release of the national guidelines and after the guideline release dates. This included looking at events around choking and cardiac/respiratory arrest in inpatient areas. There were five deaths post-implementation of the guidelines that were considered to have serious enough error associated with the resuscitation process. This was down from 18 prior to the release of the guidelines. However, our survey showed that despite organisations reporting 100% compliance with the implementation of the guidelines, around half of frontline clinical staff were not aware of them. Although our survey responses show a contradiction between organisational and clinical staff awareness, our analysis suggests a reduction in moderate and severe harm cases and of deaths. There is evidence of a reduction in the worst types of error resulting in death, albeit with small numbers. In 2008, the National Patient Safety Agency issued a Rapid Response Report (RRR) aimed at health-care organisations providing inpatient care for mental health and learning disability patients, requiring organisations to make proper provision for life support and resuscitation for these patients. This paper examines whether effective implementation of the RRR recommendations had occurred across health providers in England. The methods used in this paper are the following: (1) Questionnaires were distributed nationally to clinical staff and implementation leads; (2) A national comparison of the number and severity of pre- and post-RRR release-related incidents involving choking/cardiac/respiratory arrest in Mental Health and Learning Disabilities settings was conducted; (3) Organisational compliance with the patient safety alert for all National Health Service Organisations in England was measured. There were five deaths post-implementation of the RRR that were considered to have serious enough error associated with the resuscitation. This was down from 18 deaths pre the RRR release. Although our survey responses show a contradiction between organisational implementation and clinical staff awareness, our analysis suggests a reduction in moderate and severe harm cases and of deaths. There is evidence of a reduction in the worst types of error resulting in death, albeit with small numbers.

A randomised controlled trial of carer-focussed multi-family group psychoeducation in bipolar disorder.

In a RCT of family psychoeducation, 47 carers of 34 patients were allocated to one of three groups; Multifamily Group Psychoeducation, Solution Focussed Group Therapy or Treatment as Usual. Carers in both the MFGP intervention and the SFGP arm demonstrated greater knowledge and reduction in burden than those in the TAU arm.

Lack of correlation between enterococcal counts and the presence of human specific fecal markers in Mississippi creek and coastal waters.

The objective of this study was to determine whether statistically valid correlations could be shown between enterococcal counts of samples from creek and coastal sites and the presence of two molecular, library-independent markers that specify human and/or sewage pollution. Four hundred ninety samples were collected between August 2007 and April 2009 to determine enterococcal counts and the presence of genetic markers for the sewage indicator organisms Methanobrevibacter smithii and Bacteroidales. The presence of human/sewage markers and enterococcal counts were higher in creek samples than coastal samples, but the higher creek levels did not statistically correlate with the either enterococcal count or the presence of the markers present in coastal samples. Furthermore, there was no correlation between enterococcal counts in coastal samples and either marker at any of the beach sites tested. The results of this investigation in Mississippi coastal waters suggest that human/sewage markers are unlikely to correlate with enterococci counts in the nearshore environment and that enterococcal counts may be indicative of other animal or environmental sources. Additionally, a study comparing conventional gel electrophoresis with capillary electrophoresis did not convincingly establish that one method was better than the other in regard to the results obtained. The capillary method does allow reproducibility of results and the ability to analyze multiple samples in a short period of time; however, the operational expenditures exceed the cost of traditional gel electrophoresis.

Salmonella rarely detected in Mississippi coastal waters and sediment.

AIMS: Standards for the rapid detection of individual pathogens from environmental samples have not been developed, but in their absence, the use of molecular-based detection methods coupled with traditional microbiology techniques allows for rapid and accurate pathogen detection from environmental waters and sediment. The aim of this research was to combine the use of enrichment with PCR for detection of Salmonella in Mississippi coastal waters and sediment and observe if that presence correlated with levels of enterococci and climatological variables. METHODS AND RESULTS: Salmonella were primarily found in samples that underwent nutrient enrichment and were present more frequently in freshwater than marine waters. Salmonella were detected infrequently in marine and freshwater sediments. There was a significant positive correlation between the presence of detectable Salmonella and the average enterococcal count. An inverse relationship, however, was observed between the frequency of detection and the levels of salinity, turbidity and sunlight exposure. CONCLUSIONS: Results from this study indicated the presence of Salmonella in Mississippi coastal waters, and sediments are very low with significant differences between freshwater and marine environments. SIGNIFICANCE AND IMPACT OF THE STUDY: Using pathogenic and novel nonpathogenic molecular markers, Salmonella do not appear to be a significant pathogenic genus along the Mississippi Coast.

A replication study of the City nurse intervention: reducing conflict and containment on three acute psychiatric wards.

Conflict and containment on acute inpatient psychiatric wards pose a threat to patient and staff safety, and it is desirable to minimize the frequency of these events. Research has indicated that certain staff attitudes and behaviours might serve to accomplish this, namely, positive appreciation, emotional regulation and effective structure. A previous test of an intervention based on these principles, on two wards, showed a good outcome. In this study, we tested the same intervention on three further wards. Two 'City nurses' were employed to work with three acute wards, assisting with the implementation of changes according to the working model of conflict and containment generation. Evaluation was via before-and-after measures, with parallel data collected from five control wards. While simple before-and-after analysis of the two experimental wards showed significant reductions in conflict and containment, when a comparison with controls was conducted, with control for patient occupancy and clustering of results by ward, no effect of the intervention was found. The results were therefore ambiguous, and neither confirm nor contradict the efficacy of the intervention. A further intervention study may need to be conducted with a larger sample size to achieve adequate statistical power.

Nurse staffing, bed numbers and the cost of acute psychiatric inpatient care in England.

The aim of this analysis was to describe the composition, variability and factors associated with nurse staffing costs in acute psychiatric inpatient care. Numbers of acute inpatient beds in England have fallen, creating an occupancy crisis. Numbers of acute inpatient nursing staff are linked to quality of care. Variance in staffing and beds has considerable resource implications, but little is known about how these costs are structured. The sample comprised survey data from 136 wards in 26 NHS Trusts, matched with nationally available data on service levels, population and outcomes. The cost of providing acute inpatient care varied fivefold between different Trusts. This variation comprised of numbers of beds/population, numbers of nurses/beds and the proportion of nurses qualified. These variations were not fully accounted for by differing levels of social deprivation. Although service provision levels in London were higher, wide variation in costs existed in every region. Associations between nursing cost per bed and performance indicators were found. As investment in acute inpatient care varies widely, we need to know much more about the relationship of inputs to outputs, so that empirically based standard service levels can be defined.

Infantile gastroenteritis in the community: a cost-of-illness study.

Rotavirus infections are the main cause of gastroenteritis in infants and children and it is expected that by the age of 5 years, nearly every child will have experienced at least one episode of rotavirus gastroenteritis. While severe cases are hospitalized, milder disease is either treated at home or by the GP, and as such the true prevalence of rotavirus infection in the community, and the burden of disease, is unknown. This paper reports the results of a cost-of-illness study which was conducted alongside a structured community surveillance study. Forty-eight percent of our sample was found to have rotavirus acute gastroenteritis; and the average total cost of a child presenting with rotavirus gastroenteritis ranged between pound sterling 59 and pound sterling 143 per episode, depending on the perspective. Given the prevalence and severity of the disease, the estimated burden of rotavirus gastroenteritis to society is pound sterling 11.5 million per year.

Constraints and blocks to change and improvement on acute psychiatric wards--lessons from the City Nurses project.

Recent years have seen sustained criticism and inspection of acute inpatient psychiatric wards, with the publication of reports and research leading to policy developments and a variety of efforts to improve perceived deficits. The City Nurses project seeks to reduce levels of conflict and containment on acute wards through the placement of expert nurses on wards to assist with the implementation of changes according to a working model of conflict and containment generation, based on previous research. Evaluation has shown significant decreases in aggression, absconding and self-harm by patients. However, in the course of working with the wards, various constraints and blocks to change have been identified and we describe these in detail in this paper. Analysis of the fieldwork diaries of the two City Nurses identified that change was hindered by limited staffing resources, problems with the physical environment and other resources, insufficient beds and the process of bed management, hierarchical ambiguity and multidisciplinary issues, the overdemanding role of the ward manager, and pervasive anxiety about the potential for serious untoward incidents and their implications for staff. We argue that sustained positive change in acute inpatient psychiatry requires these underlying structural issues to be both acknowledged and, if possible, resolved.

Reflections on the process of change on acute psychiatric wards during the City Nurse Project.

The intention of this paper is to discuss the process of therapeutic change on two acute psychiatric wards during a research project that aimed to reduce conflict and containment. Analysis of fieldwork notes, reflection, team discussion and supervision. The City Nurse Project successfully reduced patient aggression, self-harm and absconding. This paper reports on the reflections made over the course of the year as changes and developments to acute wards took place. Specifically discussed are the beneficial effects of an action research approach, the role of the City Nurse, support for ward managers, education and training, clinical supervision as well as difficulties and barriers to the overall process of change. At an interim stage of the project, the staff have shown a willingness to engage in efforts to change and improve two acute wards. This paper shows the potential to improve acute wards and produce positive outcomes using a working model.

Preliminary outcomes of a trial to reduce conflict and containment on acute psychiatric wards: City Nurses.

Acute psychiatric wards experience high levels of conflict behaviours (violence, absconding, self-harm, rule breaking and medication refusal) by patients. These events cause stress and injury to staff and patients. Their management through containment methods (e.g. sedation, restraint, seclusion) is contentious, and nurses are ambivalent about their use. The aim of this study was to reduce conflict and containment on two acute psychiatric wards through changes in nurses' beliefs, attitudes and practices. Two 'City Nurses' were employed to work with two acute wards for 1 year, assisting with the implementation of changes according to a working model of conflict and containment generation, itself based on previous research. Evaluation was via before-and-after measures. Statistically and clinically significant decreases in conflict occurred, with falls in aggression, absconding and self-harm. Ward atmosphere improved and nurse-patient interaction rates increased. There was no significant change in containment method use. Significant reductions in aggression, absconding and self-harm can be achieved on acute psychiatric wards. However, it does not appear that containment can be reduced, even through large reductions in conflict.

Short-term cost effectiveness and long-term cost analysis comparing laparoscopic Nissen fundoplication with proton-pump inhibitor maintenance for gastro-oesophageal reflux disease.

BACKGROUND: This study examined the short-term cost-effectiveness and long-term cost of laparoscopic Nissen fundoplication (LNF) versus maintenance proton-pump inhibitor (PPI) medication for severe gastro-oesophageal reflux disease (GORD) based on a randomized clinical trial. METHODS: Costs and outcomes for 12 months were obtained from the first 100 patients in the trial. Detailed costing was performed using resource use data from hospital records and general practitioners' notes. Short-term incremental cost-effectiveness ratios, calculated as the cost difference divided by the effectiveness difference between LNF and PPI therapy, were analysed using net benefit and bootstrap approaches. Long-term cost was examined using sensitivity analyses incorporating published data from other large series. RESULTS: The incremental cost of LNF compared with PPI therapy per additional patient returned to a physiologically normal acid score (less than 13.9) at 3 months was pound5515 (95 per cent confidence interval (c.i.) pound3655 to pound13 400) and the incremental cost per point improvement in combined Gastro-Intestinal and Psychological Well-being score at 12 months was pound293 (90 per cent c.i. pound149 to pound5250). On average, LNF cost pound2247 (95 per cent c.i. pound2020 to pound2473) more than PPI therapy in year 1 and broke even in year 8. Break-even was highly sensitive to hospital unit costs but less sensitive to PPI ingestion rate after LNF, LNF reoperation rate, PPI relapse rate, future PPI price, PPI dose escalation and discount rate. CONCLUSION: From a National Health Service perspective, LNF may be cost-saving after 8 years compared with maintenance PPI therapy for the treatment of GORD.

Retention of atherogenic lipoproteins in atherogenesis.

Atherosclerosis is a multifactorial disease whose pathogenesis is still unclear. Mounting evidence, however, supports the concept that subendothelial retention of apoB100-containing lipoproteins is the initiating event in atherogenesis. Subsequently, a series of biological responses to this retained material leads to specific molecular and cellular processes that promote lesion formation.

A randomized controlled trial of the NEAT expandable tip continence device.

Urethral devices are one conservative management option for stress and mixed urinary incontinence, but there is little published data about their use. The aims of this study were to assess the safety and efficacy of a new urethral device (NEAT) and compare it with the Reliance Insert. The ease of use of both devices was then evaluated. Twenty-four women with mixed or stress urinary incontinence, patients at our tertiary care urogynecology unit and who met the inclusion and exclusion criteria, were enrolled in the study. Study subjects were blinded and randomly assigned to a device group. Device efficacy was assessed by pad weighing at 0 and 4 months. Success was defined as a 50% or greater reduction in urine loss using the formula 100[(pad weight without device -pad weight with device)/pad weight with device]. Safety was evaluated using urinalysis and urine cultures. Ease of use assessment scales were also completed. Eleven patients were randomized to the Reliance Insert and 13 to the NEAT device. There were no significant differences between the two groups in age, height, weight, duration of incontinence, pad weight, leakage score, parity or quality of life score. Based on the pad weight success formula, there was no significant difference in device success between the two groups at 4 months. Women who were postmenopausal had a trend towards a higher level of success in reduction of their pad weight. Previous treatment, diagnosis and hormone replacement therapy all had no relationship to device success. Leakage score data showed that subjects had a significant decrease in urine leakage when using either device. There was no statistically significant difference in ease of use between the two devices. Adverse symptoms most commonly noted were awareness of the device (62.5%), urgency (29.2%), and urethral discomfort or pain (20.8%). One urinary tract infection (UTI) was observed. The most common finding on urinalysis was trace hematuria (15.8%). Our conclusions are that the NEAT device appears to be at least as effective and safe as the Reliance Insert. Both devices are effective at decreasing urine leakage in patients with stress or mixed urinary incontinence. The risk of UTI is low, but these devices may cause trace hematuria.

The illegality of private health care in Canada.

We addressed the question of whether private health care is illegal in Canada by surveying the health insurance legislation of all 10 provinces. Our survey revealed multiple layers of regulation that seem to have as their primary objective preventing the public sector from subsidizing the private sector, as opposed to rendering privately funded practice illegal. Private insurance for medically necessary hospital and physician services is illegal in only 6 of the 10 provinces. Nonetheless, a significant private sector has not developed in any of the 4 provinces that do permit private insurance coverage. The absence of a significant private sector is probably best explained by the prohibitions on the subsidy of private practice by public plans, measures that prevent physicians from topping up their public sector incomes with private fees.
