Dementia ECHO: Evaluation of a telementoring programme to increase dementia knowledge and skills in First Nations-led health services.

INTRODUCTION: High rates of dementia among Australian First Nations' peoples have resulted in an increased demand for dementia knowledge and skills among the primary health care professionals in these communities. The Dementia Extension for Community Healthcare Outcomes (ECHO) program aims to be a culturally safe way of increasing local health workforce capacity by facilitating dementia knowledge, skills and confidence among primary care professionals in First Nations community settings. Dementia ECHO is based on the international evidence-based telementoring programme, Project Extension for Community Healthcare Outcomes. Every Dementia ECHO session is delivered by videoconference and comprises a specialist-led presentation and a case discussion from a primary care health service participant. The aims of this study were to assess the uptake and reach of Dementia ECHO; examine the perceived importance of dementia care and dementia education among Aboriginal and Torres Strait Islander Community Controlled Health Service staff; and evaluate the potential impact of Dementia ECHO on health service staff pertaining to dementia knowledge, confidence to provide dementia care and professional isolation. METHOD: Dementia ECHO service activity data maintained by the programme providers was reviewed to determine uptake and reach. A pre-implementation survey examined Aboriginal and Torres Strait Islander Community Controlled Health Service staff perspectives on the importance of dementia education and the priority of a range of health issues. After each Dementia ECHO session, a brief online survey gathered quantitative and qualitative data regarding the potential impact of the session. RESULTS: Of 30 completed pre-implementation surveys, all staff rated dementia education as either very important or important. Salient themes highlighting why it is important are presented. When asked to rank six different health priorities, dementia (n = 10) and chronic disease (n = 10) were placed as the top priority. The brief post-session feedback provided 44 complete survey responses demonstrating: perceived improvement in dementia knowledge and skills (88.4%); increased confidence to provide dementia care (83%); and a reduction in professional isolation (88%). CONCLUSION: Dementia ECHO addresses a gap in dementia education that is much needed in health professionals with increasing numbers of First Nations people living with dementia. This current study shows that attending an evidence-based telementoring programme, such as Dementia ECHO, can increase dementia knowledge and confidence to care for someone living with dementia and their families.

The effects of low frequency Repetitive Transcranial Magnetic Stimulation (rTMS) and sham condition rTMS on behavioural language in chronic non-fluent aphasia: Short term outcomes.

INTRODUCTION: The application of low frequency (1 Hz) Repetitive Transcranial Magnetic Stimulation (rTMS) to right hemisphere (RH) language homologues in non-fluent aphasic populations has yielded improvements in behavioural language function, up to 43 months post stimulation. Functional imaging studies have demonstrated RH language homologue "overactivation" post left inferior frontal gyrus (IFG) damage, in chronic non-fluent aphasia. The effects of low frequency (inhibitory) rTMS are postulated to be as a result of a reduction of overactivation in RH language homologues, facilitating the reorganisation of neural language networks. METHODS: Low frequency (1 Hz) rTMS was applied to the anterior portion of a Broca's area homologue (pars triangularis), for 20 minutes per day for 10 days, using a stereotactic neuronavigational system. Twelve non-fluent aphasic patients (six real stimulation and six sham), 2-10 years post stroke were stimulated. Behavioural language outcome measures were taken at baseline and 1 week post rTMS. RESULTS: Comparisons between the real stimulation and sham conditions indicated significant main effects between the stimulation and sham groups to 1 week post stimulation for naming accuracy, latency and repetition. CONCLUSIONS: This study indicates that rTMS has the capacity to modulate neural language networks, to facilitate improvements in behavioural language function, 1 week post TMS.
