Family support and cardiac rehabilitation: A comparative study of the experiences of South Asian and White-European patients and their carer's living in the United Kingdom

Background: Effective lifestyle modification facilitated by cardiac rehabilitation is known to reduce the occurrence of adverse coronary events and mortality. South Asians have poorer outcomes after a myocardial infarction than the general UK population, but little is known about their experiences of family support, cardiac rehabilitation and lifestyle change. Aims: To explore the nature of family support available to a sample of South Asian and White-European cardiac patients and to highlight similarities and differences between these groups with regard to cardiac rehabilitation and lifestyle modification. Methods: Using a qualitative approach, semi-structured interviews (in 1 of 6 languages) were conducted by researchers with; 45 South Asian patients and 37 carers and 20 White-European patients and 17 carers. Interviews were conducted in a home setting, up to eighteen months after discharge from hospital following myocardial infarction, coronary artery bypass surgery or unstable angina. Results: The main themes that emerged related to the provision of advice and information, family support and burden, dietary change and exercise regimes. Conclusions: Several cultural and ethnic differences were identified between patients and their families alongside similarities, irrespective of ethnicity. These may represent generic characteristics of recovery after a cardiac event. Health professionals should develop a cultural repertoire to engage with diversity and difference. Not every difficulty a person encounters as they try to access appropriate service delivery can be attributed to ethnic background. By improving services generally, support for South Asian populations can be improved. The challenge is to know when ethnicity makes a difference and mediates a person's relationship with service support and when it does not. (C) 2007 European Society of Cardiology.

Glycol Methacrylate Embedding and Microwave Staining for Light Microscopy of the Mouse Cochlea

This study examined the utility of a methacrylate-based embedding medium and microwave staining for light microscopic quantification of hair cells and spiral ganglion cells in the mouse cochlea. The most important phase of the preparation process involved slowing down the polymerization process. The tissue molecules so locked within the plastic matrix produced excellent preservation of the organ of Corti and adjacent structures including the spiral ganglion, as well as tissue ionic charges. Excitable by microwaves, these ionic charges accelerated the movement of the basic dye (hematoxylin) into the tissue, reducing the time for this segment of the staining process from approximately 45 minutes to 1-2 minutes. When embedded in glycol methacrylate (GMA), acidic dyes show less stain-cell affinity so that staining intensity and time cannot be improved significantly. However, addition of color extenders to the counterstain eosin produced distinguished staining of all tissue constituents. Thus, a combination of GMA embedding medium, use of the microwave for staining and addition of color extenders to the counterstain generated excellent structural resolution and contrast. This made both hair cell and spiral ganglion cell counts possible from within the same specimen and provided an opportunity for qualitative evaluation as well

Culture and communication in ethically appropriate care

yesThis article considers the difficulties with using Gillon's model for health care ethics in the context of clinical practice. Everyday difficulties can arise when caring for people from different ethnic and cultural backgrounds, especially when they speak little or no English. A case is presented that establishes, owing to language and cultural barriers, that midwives may have difficulty in providing ethically appropriate care to women of Pakistani Muslim origin in the UK. The use of interpreters is discussed; however, there are limitations and counter arguments to their use. Training is identified as needed to prepare service providers and midwives for meeting the needs of a culturally diverse maternity population

The use of biomedicine, complementary and alternative medicine, and ethno-medicine for the treatment of epilepsy among people of South Asian origin in the UK

Studies have shown that a significant proportion of people with epilepsy use complementary and alternative medicine (CAM). CAM use is known to vary between different ethnic groups and cultural contexts; however, little attention has been devoted to inter-ethnic differences within the UK population. We studied the use of biomedicine, complementary and alternative medicine, and ethnomedicine in a sample of people with epilepsy of South Asian origin living in the north of England

The impact of personalisation on people from Chinese backgrounds: accounts of social care experience

The limited research that considers people from black and minority ethnic communities experiences of personalisation tends to focus on personal budgets rather than personalisation per se. This article provides an opportunity to hear the voices of people from Chinese backgrounds and their experiences of personalisation. The study used individual semi-structured interviews and focus groups to collect data from people from Chinese backgrounds who lived in England, were aged between 18 and 70 and received social care for a physical disability. Data were analysed using an iterative and thematic approach, with early analysis informing the subsequent analytical rounds. The findings reveal that personalisation has the potential to transform the lives of people from Chinese backgrounds, especially when tailored support is available for people to understand and access personal budgets and put them to creative use. However, the impact of personalisation is barely evident because few eligible individuals access personal budgets or participate in co-production. This is related to a lack of encouragement for service users to become genuine partners in understanding, designing, commissioning and accessing a diverse range of social care services to meet their cultural and social care needs

Satisfaction with social care: The experiences of people from Chinese backgrounds with physical disabilities

This is the peer reviewed version of the following article: Echo Yuet Wah Yeung, Martin Partridge, and Fiona Irvine, ‘Satisfaction with social care: the experiences of people from Chinese backgrounds with physical disabilities’, health and Social Care, Vol. 24 (6): 144-154, June 2015, DOI: https://doi.org/10.1111/hsc.12264. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.The satisfaction of social care among service users provides an important indication of how services are performing. Although there is evidence to suggest that people from black and minority ethnic communities experience less satisfaction with social care than majority groups, there is little literature which focuses specifically on people from Chinese backgrounds in England. This article provides an opportunity to hear the voices of people from Chinese backgrounds and their experiences of social care for a physical disability. Individual semi-structured interviews and focus groups were conducted in 2012 and 2013 respectively with people from Chinese backgrounds who lived in England, were aged between 18 and 70, and received social care for a physical disability. Interview and focus group transcripts were analysed using a thematic approach. The findings show that language difference created a structural barrier for most participants to negotiating access to and navigating through social care. Language difference and the cultural expectation that families should look after their own were main factors that explained their late utilisation of social care. Because of limited social support, many families struggled to meet the long-term care needs of their relative with a physical disability and hence initially welcome the input of social care. However, many found that social care could not adequately meet their needs but did not feel that they had the right to voice their dissatisfaction. They would either stop using social care services or become more reliant on their family for support. Chinese welfare organisations play a crucial role to meet the cultural and linguistic needs of people from Chinese backgrounds. Closer collaboration between local authorities and Chinese welfare organisations is needed to enable an effective use of social care and community resources to meet the needs of people from Chinese backgrounds with physical disabilities.Peer reviewedFinal Accepted Versio

Development and evaluation of tools and an intervention to improve patient- and carer-centred outcomes in Longer-Term Stroke care and exploration of adjustment post stroke: the LoTS care research programme

Background: Evidence-based care pathways are required to support stroke patients and their carers in the longer term. Aims: The twofold aim of this programme of four interlinking projects was to enhance the care of stroke survivors and their carers in the first year after stroke and gain insights into the process of adjustment. Methods and results: We updated and further refined a purposely developed system of care (project 1) predicated on a patient-centred structured assessment designed to address areas of importance to patients and carers. The structured assessment is linked to evidence-based treatment algorithms, which we updated using a structured protocol: reviewing available guidelines, Cochrane reviews and randomised trials. A pragmatic cluster randomised controlled trial evaluation of the clinical effectiveness and cost-effectiveness of this system of care was undertaken in 29 community-based UK stroke care co-ordinator services (project 2). In total, 15 services provided the system of care and 14 continued with usual practice. The primary objective was to determine whether the intervention improved patient psychological outcomes (General Health Questionnaire-12) at 6 months; secondary objectives included functional outcomes for patients, outcomes for carers and cost-effectiveness, as measured through self-completed postal questionnaires at 6 and 12 months. A total of 800 patients and 208 carers were recruited; numbers of participants and their baseline characteristics were well balanced between intervention and control services. There was no evidence of statistically significant differences in primary or secondary end points or adverse events between the two groups, nor evidence of cost-effectiveness. Intervention compliance was high, indicating that this is an appropriate approach to implement evidence into clinical practice. A 22-item Longer-term Unmet Needs after Stroke (LUNS) questionnaire was developed and robustly tested (project 3). A pack including the LUNS questionnaire and outcome assessments of mood and social activity was posted to participants 3 or 6 months after stroke to assess acceptability and validity. The LUNS questionnaire was re-sent 1 week after return of the first pack to assess test–retest reliability. In total, 850 patients were recruited and the acceptability, validity and test–retest reliability of the LUNS questionnaire as a screening tool for post-stroke unmet need were confirmed. This tool is now available for clinical use. An in-depth qualitative investigation was undertaken with 22 patients (and carers) at least 1 year after stroke (project 4) to gain further insights into the experience of adjustment. This included initial semistructured interviews, limited observations and solicited diaries with a follow-up interview 3–4 months after the initial interview and highlighted a range of different trajectories for post-stroke recovery. Conclusions: The programme has been completed as planned, including one of the largest ever stroke rehabilitation trials. This work highlights that successfully addressing the needs of a heterogeneous post-stroke population remains problematic. Future work could explore stratifying patients and targeting services towards patients (and carers) with specific needs, leading to a more specialised bespoke service. The newly developed LUNS questionnaire and the qualitative work will help inform such services

Age, Ethnicity and Equalities: Synthesising Policy and Practice Messages from Two Recent Studies of Elder Abuse in the UK

Two recent studies of elder abuse in the UK are located in current policy contexts of adult safeguarding. After describing the studies, the discussion draws out their central messages and identifies the challenges that the studies present to recent policy debates and innovations. These relate to the need to properly integrate both wider older people’s issues and issues of racism and ethnicity within developments in adult safeguarding policy as well as social care services as the personalisation agenda advances

Automated differentiation of wide QRS complex tachycardia using QRS complex polarity

BACKGROUND: Wide QRS complex tachycardia (WCT) differentiation into ventricular tachycardia (VT) and supraventricular wide complex tachycardia (SWCT) remains challenging despite numerous 12-lead electrocardiogram (ECG) criteria and algorithms. Automated solutions leveraging computerized ECG interpretation (CEI) measurements and engineered features offer practical ways to improve diagnostic accuracy. We propose automated algorithms based on (i) WCT QRS polarity direction (WCT Polarity Code [WCT-PC]) and (ii) QRS polarity shifts between WCT and baseline ECGs (QRS Polarity Shift [QRS-PS]). METHODS: In a three-part study, we derive and validate machine learning (ML) models-logistic regression (LR), artificial neural network (ANN), Random Forests (RF), support vector machine (SVM), and ensemble learning (EL)-using engineered (WCT-PC and QRS-PS) and previously established WCT differentiation features. Part 1 uses WCT ECG measurements alone, Part 2 pairs WCT and baseline ECG features, and Part 3 combines all features used in Parts 1 and 2 RESULTS: Among 235 WCT patients (158 SWCT, 77 VT), 103 had gold standard diagnoses. Part 1 models achieved AUCs of 0.86-0.88 using WCT ECG features alone. Part 2 improved accuracy with paired ECGs (AUCs 0.90-0.93). Part 3 showed variable results (AUC 0.72-0.93), with RF and SVM performing best. CONCLUSIONS: Incorporating engineered parameters related to QRS polarity direction and shifts can yield effective WCT differentiation, presenting a promising approach for automated CEI algorithms

Computerized electrocardiogram data transformation enables effective algorithmic differentiation of wide QRS complex tachycardias

BACKGROUND: Accurate automated wide QRS complex tachycardia (WCT) differentiation into ventricular tachycardia (VT) and supraventricular wide complex tachycardia (SWCT) can be accomplished using calculations derived from computerized electrocardiogram (ECG) data of paired WCT and baseline ECGs. OBJECTIVE: Develop and trial novel WCT differentiation approaches for patients with and without a corresponding baseline ECG. METHODS: We developed and trialed WCT differentiation models comprised of novel and previously described parameters derived from WCT and baseline ECG data. In Part 1, a derivation cohort was used to evaluate five different classification models: logistic regression (LR), artificial neural network (ANN), Random Forests [RF], support vector machine (SVM), and ensemble learning (EL). In Part 2, a separate validation cohort was used to prospectively evaluate the performance of two LR models using parameters generated from the WCT ECG alone (Solo Model) and paired WCT and baseline ECGs (Paired Model). RESULTS: Of the 421 patients of the derivation cohort (Part 1), a favorable area under the receiver operating characteristic curve (AUC) by all modeling subtypes: LR (0.96), ANN (0.96), RF (0.96), SVM (0.96), and EL (0.97). Of the 235 patients of the validation cohort (Part 2), the Solo Model and Paired Model achieved a favorable AUC for 103 patients with (Solo Model 0.87; Paired Model 0.95) and 132 patients without (Solo Model 0.84; Paired Model 0.95) a corroborating electrophysiology procedure or intracardiac device recording. CONCLUSION: Accurate WCT differentiation may be accomplished using computerized data of (i) the WCT ECG alone and (ii) paired WCT and baseline ECGs
