An audit of dementia education and training in UK health and social care: a comparison with national benchmark standards.

BACKGROUND: Despite people living with dementia representing a significant proportion of health and social care users, until recently in the United Kingdom (UK) there were no prescribed standards for dementia education and training. This audit sought to review the extent and nature of dementia education and training offered to health and social care staff in the UK against the standards described in the 2015 Dementia Training Standards Framework, which describes the knowledge and skills required of the UK dementia workforce. METHODS: This audit presents national data concerning the design, delivery, target audience, length, level, content, format of training, number of staff trained and frequency of delivery within existing dementia training programmes offered to health and social care staff. The Dementia Training Standards Framework was used as a reference for respondents to describe the subjects and learning outcomes associated with their training. RESULTS: The findings are presented from 614 respondents offering 386 training packages, which indicated variations in the extent and quality of training. Many training packages addressed the subjects of 'person-centred care', 'communication', 'interaction and behaviour in dementia care', and 'dementia awareness'. Few training packages addressed subjects concerning 'pharmacological interventions in dementia care', 'leadership' and 'end of life care'. Fewer than 40% of The Dementia Training Standards Framework learning outcomes targeted to staff with regular contact with people with dementia or in leadership roles were covered by the reported packages. However, for training targeted at increasing dementia awareness more than 70% of the learning outcomes identified in The Dementia Training Standards Framework were addressed. Many training packages are not of sufficient duration to derive impact; although the majority employed delivery methods likely to be effective. CONCLUSIONS: The development of new and existing training and education should take account of subjects that are currently underrepresented and ensure that training reflects the Training Standard Framework and evidence regarding best practice for delivery. Lessons regarding the limitations of training in the UK serve as a useful illustration of the challenge of implementing national dementia training standards; particularly for countries who are developing or have recently implemented national dementia strategies.

Young-onset dementia and the need for specialist care: a national and international perspective.

OBJECTIVES: Receiving a timely and accurate diagnosis and gaining access to age-appropriate support for younger people living with dementia (YPD) remains a challenge both in the UK and internationally because the focus of most dementia services is primarily upon the needs of older people. The political case to improve services for YPD depends upon the establishment of an understanding of the clinical symptoms, an unequivocal evidence base about need and an accurate evaluation of the size of the population affected. This short report assesses the evidence base from international studies regarding service design and delivery. The goal is to raise awareness, advance best practice and galvanise the international community to address the serious underfunding and underprovision of care for this marginalised group. CONCLUSION: The current evidence suggests that there are universal problems, regardless of continent, with delays to diagnosis and poor understanding of optimum models for service provision and long-term care.

A logical model of HIV-1 interactions with the T-cell activation signalling pathway.

MOTIVATION: Human immunodeficiency virus type 1 (HIV-1) hijacks host cellular processes to replicate within its host. Through interactions with host proteins, it perturbs and interrupts signaling pathways that alter key cellular functions. Although networks of viral-host interactions have been relatively well characterized, the dynamics of the perturbation process is poorly understood. Dynamic models of infection have the potential to provide insights into the HIV-1 host interaction. RESULTS: We employed a logical signal flow network to model the dynamic interactions between HIV-1 proteins and key human signal transduction pathways necessary for activation of CD4+ T lymphocytes. We integrated viral-host interaction and host signal transduction data into a dynamic logical model comprised of 137 nodes (16 HIV-1 and 121 human proteins) and 336 interactions collected from the HIV-1 Human Interaction Database. The model reproduced expected patterns of T-cell activation, co-stimulation and co-inhibition. After simulations, we identified 26 host cell factors, including MAPK1&3, Ikkb-Ikky-Ikka and PKA, which contribute to the net activation or inhibition of viral proteins. Through in silico knockouts, the model identified a further nine host cell factors, including members of the PI3K signalling pathway that are essential to viral replication. Simulation results intersected with the findings of three siRNA gene knockout studies and identified potential drug targets. Our results demonstrate how viral infection causes the cell to lose control of its signalling system. Logical Boolean modelling therefore provides a useful approach for analysing the dynamics of host-viral interactions with potential applications for drug discovery.

Determinants of burden in those who care for someone with dementia.

OBJECTIVES: Caregiver burden is a key measure in caregiver research and is frequently used as a baseline measure in intervention studies. Previous research has found numerous factors associated with caregiver burden such as the relationship quality between carer and patient, the patient's cognitive ability, behavioural and psychological symptoms displayed by the patient, caregiver gender, adverse life events to name a few. Many studies have investigated these factors singularly however current thought suggests a multi-factorial role and inter-dependence of these factors. Based on this it was decided to investigate factors associated with caregiver burden using a multiple regression analysis in order to ascertain the predictive quality of these factors of caregiver burden. METHOD: Cross-sectional study using validated measures of a patient's cognitive ability, ability to carry out day-to-day tasks and behavioural and psychological symptoms. Caregiver outcomes used are caregiver burden, relationship quality, caregiver confidence, experience of adverse life events, neuroticism, age and gender. Interviews and questionnaires were carried out on 74 patients diagnosed with dementia and their main caregivers from the Midlands of England. RESULTS: Multiple regression analysis showed that caregiver overload, carer-patient relationship quality, the experience of adverse life events, caregiver gender, caregivers' level of neuroticism, caregiver role captivity and the level of caregiver confidence accounted for over 80% of the variance in caregiver burden. CONCLUSION: These results confirm previous correlational research on caregiver burden. Furthermore, due to the use of multiple regression analysis the findings also show factors that are clear predictors of caregiver burden and we offer possible suggestions from these findings on future clinical practice interventions on caregiver burden.

Awareness of memory functioning in early Alzheimer's disease: lessons from a comparison with healthy older people and young adults.

To compare awareness of memory in people with early Alzheimer's disease (AD) with older and younger control groups in order to clarify the contributions of disease and ageing. Twenty-one individuals with early AD, 32 older people (OP) and 32 younger people (YP) estimated their performance before and following each of four tests of memory. Those with AD significantly overestimated performance prior to testing, confirming the presence of unawareness for prediction. Their estimates were adjusted for age in a similar way to those of OP, who predicted their performance accurately. Younger people significantly underestimated their performance. Following memory tests, YP and those with AD significantly adjusted their ratings towards greater accuracy but on average those with AD still overestimated. There were variations in post-test ratings from over to under prediction in all three groups. Heightened awareness post-performance may open possibilities of cognitive rehabilitation to consolidate momentary into more long-term awareness, whilst the operation of possible psychosocial influences suggests that emotion oriented interventions to increase acceptance and decrease shame might be helpful.

Cognitive functioning in Parkinson's disease: in relation to prevalence of dementia and psychiatric diagnosis.

Forty-three neurologically and psychiatrically assessed patients with idiopathic Parkinson's disease (PD) underwent detailed cognitive assessment. Cognitive deficits typical of senile dementia of Alzheimer's type (SDAT) were found in 7% but the majority showed definite impairments not typical of SDAT. Cognitive impairment was significantly more likely in those with more severe PD symptoms. There was substantial agreement between psychiatric diagnosis and psychological picture of SDAT and some links were found between other diagnostic categories and nature of cognitive functioning. However, cognitive deficits were also found in two-thirds of patients with no psychiatric diagnosis.
