Stakeholder views on the barriers and facilitators of psychosocial interventions to address reduction in aggressive challenging behaviour in adults with intellectual disabilities.

Background: Success of psychosocial interventions in reducing aggressive challenging behaviour is likely to be related not only to mechanistic aspects, but also to therapeutic and system factors. The study aims to examine the facilitators and barriers that influence whether psychosocial interventions for aggressive challenging behaviour in adults with intellectual disabilities lead to positive change. Methods: We conducted 42 semi-structured interviews with adults with intellectual disabilities and aggressive challenging behaviour, family/paid carers, and professionals engaged in or delivering a psychosocial intervention across the UK. Data were analysed thematically using a framework approach. Results: Stakeholders considered therapeutic and supportive relationships and personalised care as facilitating factors of psychosocial interventions to address aggressive challenging behaviour. The operational structure of community intellectual disability services and conflicting expectations of professionals and carers were the main contextual barriers that impeded the implementation of psychosocial interventions addressing aggressive challenging behaviour in adults with intellectual disabilities. Conclusions: Findings highlight the valued components that maximise positive change in adults with intellectual disabilities who display aggressive challenging behaviour. Several operational adjustments including referral criteria, roles of professionals and workforce issues need to be addressed in services to maximise the implementation of psychosocial interventions to reduce aggressive challenging behaviour in adults with intellectual disabilities.

The current study looked at what factors that lead to good outcomes from therapies that aim to reduce aggressive challenging behaviour in adults with learning disabilities. We also looked at the factors that may prevent positive change ( i.e., reduction in aggressive challenging behaviour). We interviewed 42 people including 14 adults with learning disabilities, 13 carers (6 family; 7 paid) and 13 professionals across the UK. All stakeholders agreed that supportive relationships between the person with a learning disability and their therapist, staff consistent, personalised therapy and involvement of the person with a learning disability and their carer(s) in care planning facilitate the reduction of aggressive challenging behaviour. On the other hand, differences in expectations between professionals and carers, personal reasons ( e.g. being the right timing for a person), and the way community learning disability services currently run may stop people from having the opportunity to take part in therapy are barriers to positive change such as reduction of aggressive challenging behaviour. The study findings highlight the valued components that maximise the positive change in adults with intellectual disabilities who display aggressive challenging behaviour. Several operational adjustments including referral criteria, roles of professionals and workforce issues need to be addressed in services to maximise the implementation of psychosocial interventions to reduce aggressive challenging behaviour in adults with intellectual disabilities.

Stakeholder perspectives on intensive support teams for adults with intellectual disabilities who display behaviour that challenges in England.

BACKGROUND: Adults with intellectual disabilities often display behaviour that challenges that is a result of biological differences, psychological challenges, and lack of appropriate social support. Intensive Support Teams (IST) are recommended to support the care needs of this group and avoid hospitalisation. However, little attention has been paid to the perspectives of stakeholders who manage, work in, or use ISTs. METHOD: Interviews and focus groups were conducted with 50 stakeholders (IST service managers and professionals, adults with intellectual disabilities, and family and paid carers) of ISTs. Services operated according to one of two service models previously identified in ISTs in England (enhanced or independent). RESULTS: Thematic analysis identified accessible and flexible support, individualised care, and the involvement of carers and other relevant agencies in management plans and reviews as features of good IST care highlighted by all stakeholder groups. IST managers and professionals described the key challenges of current IST provision as unclear referral criteria, limited interfaces with other local services, and perceived threats associated with funding and staff retention. Findings were similar between the two IST models. CONCLUSIONS: ISTs are able to offer care and specialist support that is valued by families, service users and other care providers. However, they face several operational challenges that should be addressed if ISTs are to reach their potential along with community intellectual disability services in supporting adults with intellectual disabilities who display behaviour that challenges in the community.

Clinical and cost evaluation of two models of specialist intensive support teams for adults with intellectual disabilities who display behaviours that challenge: the IST-ID mixed-methods study.

BACKGROUND: Intensive support teams (ISTs) are recommended for individuals with intellectual disabilities who display behaviours that challenge. However, there is currently little evidence about the clinical and cost-effectiveness of IST models operating in England. AIMS: To investigate the clinical and cost-effectiveness of IST models. METHOD: We carried out a cohort study to evaluate the clinical and cost-effectiveness of two previously identified IST models (independent and enhanced) in England. Adult participants (n = 226) from 21 ISTs (ten independent and 11 enhanced) were enrolled. The primary outcome was change in challenging behaviour between baseline and 9 months as measured by the Aberrant Behaviour Checklist-Community version 2. RESULTS: We found no statistically significant differences between models for the primary outcome (adjusted ß = 4.27; 95% CI -6.34 to 14.87; P = 0.430) or any secondary outcomes. Quality-adjusted life-years (0.0158; 95% CI: -0.0088 to 0.0508) and costs (£3409.95; 95% CI -£9957.92 to £4039.89) of the two models were comparable. CONCLUSIONS: The study provides evidence that both models were associated with clinical improvement for similar costs at follow-up. We recommend that the choice of service model should rest with local services. Further research should investigate the critical components of IST care to inform the development of fidelity criteria, and policy makers should consider whether roll out of such teams should be mandated.

Effect of passive myocardium on the compliance of porcine coronary arteries.

The objective of this study was to determine the effect of passive myocardium on the coronary arteries under distension and compression. To simulate distension and compression, we placed a diastolic-arrested heart in a Lucite box, where both the intravascular pressure and external (box) pressure were varied independently and expressed as a pressure difference (DeltaP = intravascular pressure - box pressure). The DeltaP-cross-sectional area relationship of the first several generations of porcine coronary arteries and the DeltaP-volume relationship of the coronary arterial tree (vessels >0.5 mm in diameter) were determined using a video densitometric technique in the range of +150 to -150 mmHg. The vasodilated left anterior descending (LAD) coronary artery of six KCl-arrested hearts were perfused with iodine and 3% Cab-O-Sil. The intravascular pressure was varied in a triangular pattern, whereas the absolute cross-sectional area of each vessel and the total arterial volume were calculated using video densitometry under different box pressures (0, 50, 100, and 150 mmHg). In the range of positive DeltaP, we found that the compliance of the proximal LAD artery in situ (4.85 +/- 3.8 x 10-3 mm2/mmHg) is smaller than that of the same artery in vitro (16.5 +/- 6 x 10-3 mm2/mmHg; P = 0.009). Hence, the myocardium restricts the compliance of the epicardial artery under distension. In the negative DeltaP range, the LAD artery does not collapse, whereas the same vessel readily collapses when tested in vitro. Hence, we conclude that myocardial tethering prevents collapse of large blood vessel under compression.
