Promoting independence in frail older people: a randomised controlled trial of a restorative care service in New Zealand.

BACKGROUND: frail older people often require tailored rehabilitation in order to remain at home, especially following a period of hospitalisation. Restorative care services aim to enhance an older person's ability to remain improve physical functioning, either at home or in residential care but evidence of their effectiveness is limited. OBJECTIVE: to evaluate the effectiveness of a restorative care service on institutional-free survival and health outcomes in frail older people referred for needs assessment in New Zealand. METHODS: a randomised controlled trial of restorative care or usual care in 105 older people at risk of permanent residential who were follow-up over 24 months. The restorative care service was delivered in short-stay residential care facilities and at participants' residences with the aim of reducing the requirement for permanent residential care. It included a comprehensive geriatric assessment and care plan developed and delivered, initially by a multi-disciplinary team and subsequently by home care assistants. RESULTS: compared with usual care, there was a non-significant absolute risk reduction of 14.3% for death or permanent residential care (8.8% for residential care and 7.2% for death alone) for the restorative care approach. There was no difference in levels of burden among caregivers. CONCLUSIONS: restorative care models that utilise case management and multi-disciplinary care may positively impact on institutional-free survival for frail older people without adversely impacting on the health of caregivers.

Central nervous system stimulants for secondary attention deficit-hyperactivity disorder after paediatric traumatic brain injury: a rationale and protocol for single patient (n-of-1) multiple cross-over trials.

BACKGROUND: It is estimated that 22,800 children were living with an Acquired Brain Injury (ABI) (0.6% of children aged under 15 years) in Australia during 2003. Many children after a traumatic brain injury will experience difficulties with attention and concentration; a condition termed secondary Attention Deficit-Hyperactivity Disorder. There is conflicting evidence on whether treatment with stimulant therapy with medications such as methylphenidate or dexamphetamine will improve the attention and behavior of children with this condition. METHODS/DESIGN: Single patient trials (n-of-1s or SPTs) evaluate the effect of titrated doses of psychostimulants methylphenidate or dexamphetamine compared to placebo on attention and behavior, in children with TBI and secondary ADHD. The aggregation of multiple SPTs will produce a population estimate of the benefit. Forty-two children will be registered into the trial through rehabilitation services at three large children's hospitals in Australia. Patients will complete up to 3 cycles of treatment. Each cycle is 2 weeks long comprising seven days each of treatment and placebo, with the first two days of each cycle considered a washout period and the data not analysed. The order of treatment and placebo is randomly allocated for each cycle. The Conners' Parent Rating Scales long forms will be employed to measure change in attention-deficit/hyperactivity and related problems of the child, and the primary outcome measure is the Conners' Global Index Parent Version. Secondary outcomes include the teacher and child (if aged > 12 years) Conners' Rating Scales, the Behaviour Rating Inventory of Executive Function among other measures. This study will provide high-level evidence using a novel methodological approach to inform clinicians about the most appropriate treatment for individual children. Through aggregation of individual trials, a population estimate of treatment effect will be provided to guide clinical practice in the treatment of children with secondary ADHD after a traumatic brain injury. DISCUSSION: This study employs an innovative methodological approach on the effectiveness of CNS stimulants for secondary ADHD from a brain injury. The findings will both guide clinicians on treatment recommendations, and inform the concept and acceptance of SPTs in paediatric research.

The Assessment of Services Promoting Independence and Recovery in Elders Trial (ASPIRE): a pre-planned meta-analysis of three independent randomised controlled trial evaluations of ageing in place initiatives in New Zealand.

INTRODUCTION: intermediate care has been developed to support older people to remain living in their own homes, combining a higher level of support with a rehabilitation focus. Evidence around their effectiveness remains mixed and there is ambiguity around the components. AIMS: to establish the impact of intermediate care on institutional free survival in frail older people referred for needs assessment in New Zealand (NZ). METHODS: pre-planned meta-analysis of three randomised controlled trials with follow-up at 3, 6, 12, 18 and 24 months. A total of 567 older people at risk of permanent institutionalisation as well as their primary informal carer (n = 234) were randomised to either intermediate or usual care. Interventions had common key features of care management, though varied in the use of ongoing care provision. RESULTS: the adjusted hazard ratio for the combined primary outcome of death or residential entry was 31% lower with a 95% confidence interval of (9%, 47%) for the intermediate care initiatives compared with usual care. CONCLUSION: intermediate care utilising a care management approach reduces a frail older person's risk of mortality and permanent institutionalisation.
