Rural general practitioner confidence in diagnosing and managing dementia: A two-stage, mixed methods study of dementia-specific training.

INTRODUCTION: Dementias a prevalent chronic healthcare condition affecting 46 million people worldwide and projected to grow in the coming years. Australians living in rural and regional areas often lack access to specialist dementia care, despite greater prevalence relative to metropolitan areas. OBJECTIVE: This study aimed to explore general practitioners (GP) understanding, confidence and attitudes towards dementia management in the rural context, and design and pilot a dementia-specific training program. DESIGN: A two-stage, mixed methods design, using qualitative and quantitative methods. Sixteen regional GPs from across Victoria participated in scoping semi-structured interviews. Fourteen separate GPs in the St Anthony Family Medical Practice group in the regional Loddon-Mallee area of Victoria completed the pilot training intervention. Pre- and post-training surveys (n = 10), as well as post-training interviews (n = 10), assessed attitude and knowledge changes. FINDINGS: Analysis of semi-structured scoping interviews indicated three themes regarding experience of dementia management, including: (1) attitudes to and experiences of dementia; (2) supporting people living with dementia; and (3) knowledge, education and training of dementia. The pilot dementia-specific training was found to improve attitudes (agreement across 24 best-practice indicators improved from 30% to 79%), knowledge (median increase of 2.5/10) and confidence in managing dementia and disclosing dementia diagnoses (median increase 3/10 and 2.75/10, respectively). DISCUSSION: General practitioners in this study lacked initial confidence in detecting and managing dementia in a rural primary care setting. A targeted training program showed improvements in these areas. CONCLUSION: Accessible, locally delivered, dementia education has the potential to improve confidence in early detection and management of people with dementia and thereby may address gaps in access to care for people living with dementia in rural settings.

A new model for general practice-led, regional, community-based, memory clinics.

BACKGROUND: Dementia is a major international health issue with high impact on the patient, relatives, and broader society. Routine screening for dementia is limited, despite known benefit of early detection and intervention on quality of care and patient outcomes. Screening is particularly limited in rural and regional areas, despite high burden and projected growth of dementia in these populations. The current study aimed to implement a new general practitioner (GP) led, multidisciplinary, model of care providing dementia detection and referral pathway to a community-based specialist clinic across six regional general practices. METHODS: Cross-sectional analysis of dementia screening and referral characteristics in the St Anthony Family Medical Practices group based in the regional area of Loddon-Mallee, Victoria. Data were collected on demographics and relevant medical history. Cognitive state was assessed using the Mini-Mental State Examination (MMSE), GP Assessment of Cognition (GPCog), and Geriatric Depression Scale (GDS). Referrals and referral outcomes were recorded for geriatrician, psycho-geriatrician, or both. RESULTS: Eight hundred and eighteenth patients over 65 years were screened, accounting for approximately 24.2% of 65 and over presentations for the practice network. Of those screened, 68.9% were indicated for referral and 30.3% of these were successfully referred. Of the indicated patients who received referrals, 34.2% declined. Many who declined referral had intermediate scores on the cognitive assessments utilized. CONCLUSION: Standardised models of care, integrated within community services, are necessary to improve access to early detection, referral and quality management of dementia. The St Anthony Memory Service model will be invaluable in informing future service development, and in particular the development of services for people living with dementia in rural and regional communities.

Effectiveness of a peer-mediated educational intervention in improving general practitioner diagnostic assessment and management of dementia: a cluster randomised controlled trial.

OBJECTIVE: Test effectiveness of an educational intervention for general practitioners (GPs) on quality of life and depression outcomes for patients. DESIGN: Double-blind, cluster randomised controlled trial. SETTING: General practices in Australia between 2007 and 2010. PARTICIPANTS: General practices were randomly allocated to the waitlist (n=37) or intervention (n=66) group, in a ratio of 1:2. A total of 2030 (1478 intervention; 552 waitlist) community-dwelling participants aged 75 years or older were recruited via 168 GPs (113 intervention; 55 waitlist). INTERVENTIONS: A practice-based academic detailing intervention led by a peer educator that included: (1) training in use of the GP assessment of cognition dementia screening instrument; (2) training in diagnosis and management based on Royal Australian College of General Practitioners Dementia Guidelines; (3) addressing GPs' barriers to dementia diagnosis; and (4) a business case outlining a cost-effective dementia assessment approach. OUTCOME MEASURES: Primary outcome measures were patient quality of life and depression; secondary outcome measures were: (1) sensitivity and specificity of GP identification of dementia; (2) referral to medical specialists and/or support services; (3) patient satisfaction with care; and (4) carer quality of life, depression and satisfaction with care. RESULTS: The educational intervention had no significant effect on patient quality of life or depression scores after 12 months. There were however improvements in secondary outcome measures including sensitivity of GP judgement of dementia (p=0.002; OR 6.0, 95% CI 1.92 to 18.73), satisfaction with GP communication for all patients (p=0.024; mean difference 2.1, 95% CI 0.27 to 3.93) and for patients with dementia (p=0.007; mean difference 7.44, 95% CI 2.02 to 12.86) and enablement of carers (p=0.0185; mean difference 24.77, 95% CI 4.15 to 45.40). CONCLUSION: Practice-based academic detailing did not improve patient quality of life or depression scores but did improve detection of dementia in primary care and patient satisfaction with GP communication.

Acute Predictors of Social Integration Following Mild Stroke.

BACKGROUND: Despite an acknowledged need to accurately predict stroke outcome, there is little empirical evidence regarding acute predictors of participation restriction post stroke. The current study examines prediction of social integration following mild stroke, using combinations of acute poststroke factors. PATIENTS AND METHODS: In a prospective, longitudinal study, a cohort of 60 stroke survivors was followed up at 6 months post stroke. Hierarchical multiple regression analyses were employed to evaluate the value of acute poststroke variables in predicting social integration at 6 months post stroke. RESULTS: A combination of age, number of comorbidities, stroke severity, social support factors, and general self-efficacy in the acute poststroke period accounted for 42% of the variance in 6-month social integration. The largest amount of variance (20%) was explained by inclusion of social support factors, including number and types of support. Post hoc analysis was conducted to establish whether marital status was the mediating variable through which early poststroke social support factors exerted influence upon subsequent social integration. The new combination of acute variables accounted for 48% of the variance in 6-month social integration. Results suggested that subjects with partners perceived higher levels of functional social support and lower levels of participation restriction. DISCUSSION: Stroke survivors with partners may receive greater amounts of companionship and encouragement from their partners, which enhances self-esteem and confidence. Such individuals are possibly more able to participate in and maintain relationships, thus improving social integration. CONCLUSIONS: Social support factors, mediated via marital status, are the strongest predictors of subsequent social integration following mild stroke.

An evaluation of the additional benefit of population screening for dementia beyond a passive case-finding approach.

OBJECTIVE: General practitioners (GPs) fail to identify more than 50% of dementia cases using the existing passive case-finding approach. Using data from the "Ageing in General Practice" study, we sought to establish the additional benefit of screening all patients over the age of 75 for dementia beyond those patients already identified by passive case-finding. METHOD: Patients were classified as "case-finding" (n = 425) or "screening" (n = 1006) based on their answers to four subjective memory related questions or their GP's clinical judgement of their dementia status. Cognitive status of each patient was formally assessed by a research nurse using the Cambridge Cognition Examination (CAMCOG-R). Patients then attended their usual GP for administration of the GP assessment of Cognition (GPCOG) dementia screening instrument, and follow-up care and/or referral as necessary in light of the outcome. RESULTS: The prevalence of dementia was significantly higher in the case-finding group (13.6%) compared to the screening group (4.6%; p < 0.01). The GPCOG had a positive predictive value (PPV) of 61% in the case-finding group and 39% in the screening group; negative predictive value was >95% in both groups. GPs and their patients both found the GPCOG to be an acceptable cognitive assessment tool. The dementia cases missed via case-finding were younger (p = 0.024) and less cognitively impaired (p = 0.020) than those detected. CONCLUSION: There is a very limited benefit of screening for dementia, as most people with dementia could be detected using a case-finding approach, and considerable potential for social and economic harm because of the low PPV associated with screening.

Multi-disciplinary rehabilitation for acquired brain injury in adults of working age.

BACKGROUND: Evidence from systematic reviews demonstrates that multi-disciplinary rehabilitation is effective in the stroke population, in which older adults predominate. However, the evidence base for the effectiveness of rehabilitation following acquired brain injury (ABI) in younger adults has not been established, perhaps because this scenario presents different methodological challenges in research. OBJECTIVES: To assess the effects of multi-disciplinary rehabilitation following ABI in adults 16 to 65 years of age. SEARCH METHODS: We ran the most recent search on 14 September 2015. We searched the Cochrane Injuries Group Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic+Embase (OvidSP), Web of Science (ISI WOS) databases, clinical trials registers, and we screened reference lists. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing multi-disciplinary rehabilitation versus routinely available local services or lower levels of intervention; or trials comparing an intervention in different settings, of different intensities or of different timing of onset. Controlled clinical trials were included, provided they met pre-defined methodological criteria. DATA COLLECTION AND ANALYSIS: Three review authors independently selected trials and rated their methodological quality. A fourth review author would have arbitrated if consensus could not be reached by discussion, but in fact, this did not occur. As in previous versions of this review, we used the method described by Van Tulder 1997 to rate the quality of trials and to perform a 'best evidence' synthesis by attributing levels of evidence on the basis of methodological quality. Risk of bias assessments were performed in parallel using standard Cochrane methodology. However, the Van Tulder system provided a more discriminative evaluation of rehabilitation trials, so we have continued to use it for our primary synthesis of evidence. We subdivided trials in terms of severity of brain injury, setting and type and timing of rehabilitation offered. MAIN RESULTS: We identified a total of 19 studies involving 3480 people. Twelve studies were of good methodological quality and seven were of lower quality, according to the van Tulder scoring system. Within the subgroup of predominantly mild brain injury, 'strong evidence' suggested that most individuals made a good recovery when appropriate information was provided, without the need for additional specific interventions. For moderate to severe injury, 'strong evidence' showed benefit from formal intervention, and 'limited evidence' indicated that commencing rehabilitation early after injury results in better outcomes. For participants with moderate to severe ABI already in rehabilitation, 'strong evidence' revealed that more intensive programmes are associated with earlier functional gains, and 'moderate evidence' suggested that continued outpatient therapy could help to sustain gains made in early post-acute rehabilitation. The context of multi-disciplinary rehabilitation appears to influence outcomes. 'Strong evidence' supports the use of a milieu-oriented model for patients with severe brain injury, in which comprehensive cognitive rehabilitation takes place in a therapeutic environment and involves a peer group of patients. 'Limited evidence' shows that specialist in-patient rehabilitation and specialist multi-disciplinary community rehabilitation may provide additional functional gains, but studies serve to highlight the particular practical and ethical restraints imposed on randomisation of severely affected individuals for whom no realistic alternatives to specialist intervention are available. AUTHORS' CONCLUSIONS: Problems following ABI vary. Consequently, different interventions and combinations of interventions are required to meet the needs of patients with different problems. Patients who present acutely to hospital with mild brain injury benefit from follow-up and appropriate information and advice. Those with moderate to severe brain injury benefit from routine follow-up so their needs for rehabilitation can be assessed. Intensive intervention appears to lead to earlier gains, and earlier intervention whilst still in emergency and acute care has been supported by limited evidence. The balance between intensity and cost-effectiveness has yet to be determined. Patients discharged from in-patient rehabilitation benefit from access to out-patient or community-based services appropriate to their needs. Group-based rehabilitation in a therapeutic milieu (where patients undergo neuropsychological rehabilitation in a therapeutic environment with a peer group of individuals facing similar challenges) represents an effective approach for patients requiring neuropsychological rehabilitation following severe brain injury. Not all questions in rehabilitation can be addressed by randomised controlled trials or other experimental approaches. For example, trial-based literature does not tell us which treatments work best for which patients over the long term, and which models of service represent value for money in the context of life-long care. In the future, such questions will need to be considered alongside practice-based evidence gathered from large systematic longitudinal cohort studies conducted in the context of routine clinical practice.

Impact of multiple low-level anticholinergic medications on anticholinergic load of community-dwelling elderly with and without dementia.

BACKGROUND: Elderly people, particularly those with dementia, are sensitive to adverse anticholinergic drug effects. This study examines the prevalence of anticholinergic medication, and anticholinergic load and its predictors, in community-dwelling elderly patients (aged 75 years and older) in Australia. METHODS: A research nurse visited the home of each participant (n = 1,044), compiled a list of current medications, and assessed participants' cognitive status using a subsection of the revised Cambridge Examination for Mental Disorders of the Elderly (CAMCOG-R). Anticholinergic load was determined for each patient using the Anticholinergic Drug Scale (ADS). RESULTS: Multivariate analysis identified several patient factors that were associated with higher anticholinergic burden, including polypharmacy (i.e. taking five or more medications) (p < 0.001), increasing age (p = 0.018), CAMCOG-R dementia (p = 0.003), depression (p = 0.003), and lower physical quality of life (p < 0.001). The dementia group (n = 86) took a significantly higher number of medications (4.6 vs. 3.9; p = 0.04), and had a significantly higher anticholinergic load (1.5 vs. 0.8; p = 0.002) than those without dementia (n = 958). Approximately 60% of the dementia group and 40% of the non-dementia group were receiving at least one anticholinergic drug. This difference was due to the higher proportion of dementia patients taking level 1 (potentially anticholinergic) (p = 0.002) and level 3 (markedly anticholinergic) (p = 0.005) drugs. CONCLUSIONS: There is considerable scope for the improvement of prescribing practices in the elderly, and particularly those with dementia. Importantly, level 1 anticholinergics have been identified as major contributors to the anticholinergic load in people with dementia. Longitudinal studies are required to determine the effects of increased and decreased anticholinergic load on cognitive function and other clinical outcomes for people with dementia.

Establishment of an effective acute stroke telemedicine program for Australia: protocol for the Victorian Stroke Telemedicine project.

RATIONALE: Urgent treatment of acute stroke in rural Australia is problematic partly because of limited access to medical specialists. Utilization of telemedicine could improve delivery of acute stroke treatments in rural communities. AIM: The study aims to demonstrate enhanced clinical decision making for use of thrombolysis within 4·5 h of ischemic stroke symptom onset in a rural setting using a telemedicine specialist support model. DESIGN: A formative program evaluation research design was used. The Victorian Stroke Telemedicine program was developed and will be evaluated over five stages to ensure successful implementation. The phases include: (a) preimplementation phase to establish the Victorian Stroke Telemedicine program including the clinical pathway, data collection tools, and technology processes; (b) pilot clinical application phase to test the pathway in up to 10 patients; (c) modification phase to refine the program; (d) full clinical implementation phase where the program is maintained for one-year; and (e) a sustainability phase to assess project outcomes over five-years. Qualitative (clinician interviews) and quantitative data (patient, clinician, costs, and technology processes) are collected in each phase. STUDY OUTCOMES: The primary outcome is to achieve a minimum 10% absolute increase in eligible patients treated with thrombolysis. Secondary outcomes are utilization of the telestroke pathway and improvements in processes of stroke care (e.g., time to brain scan). We will report door to telemedicine consultation time, length of telemedicine consultation, clinical utility and acceptability from the perspective of clinicians, and 90-day patient outcomes. SUMMARY: This research will provide evidence for an effective telestroke program for use in regional Australian hospitals.

Influence of rurality on diagnosing dementia in Australian general practice.

This article reviews the literature concerning barriers in making a diagnosis of dementia in general practice and examines these from a rural perspective. It is proposed that the increasing prevalence of dementia in coming years in Australia will be felt most keenly in rural communities where there are already shortages of GPs and dementia-specific services to manage growing demand. Evidence suggests that dementia is often not specifically diagnosed by GPs and that this is a global issue. There are many barriers to the diagnosis of dementia in general practice, including time constraints, diagnostic uncertainty, denial of symptoms by patients and families, and stigma. This review examines these barriers and their impact on making a dementia diagnosis from a rural general practice perspective. Identification of these practice issues and their influence on service delivery is essential to inform relevant policy decisions and to improve dementia management in rural general practice.

Ageing in general practice (AGP) trial: a cluster randomised trial to examine the effectiveness of peer education on GP diagnostic assessment and management of dementia.

BACKGROUND: Dementia is increasing in prevalence as the population ages. An earlier rather than later diagnosis allows persons with dementia and their families to plan ahead and access appropriate management. However, most diagnoses are made by general practitioners (GPs) later in the course of the disease and are associated with management that is poorly adherent to recommended guidelines. This trial examines the effectiveness of a peer led dementia educational intervention for GPs. METHODS: The study is a cluster randomised trial, conducted across three states and five sites. All GPs will complete an audit of their consenting patients aged 75 years or more at three time points - baseline, 12 and 24 months. GPs allocated to the intervention group will receive two educational sessions from a peer GP or nurse, and will administer the GPCOG to consenting patients at baseline and 12 months. The first education session will provide information about dementia and the second will provide individualised feedback on audit results. GPs in the waitlist group will receive the RACGP Guidelines by post following the 12 month audit OUTCOMES: Primary outcomes are carer and consumer quality of life and depression. Secondary outcomes include: rates of GP identification of dementia compared to a more detailed gold standard assessment conducted in the patient's home; GP identification of differential diagnoses including reversible causes of cognitive impairment; and GP referral to specialists, Alzheimers' Australia and support services. A "case finding" and a "screening" group will be compared and the psychometrics of the GPCOG will be examined. SAMPLE SIZE: Approximately 2,000 subjects aged 75 years and over will be recruited through approximately 160 GPs, to yield approximately 200 subjects with dementia (reducing to 168 by 24 months). DISCUSSION: The trial outlined in this paper has been peer reviewed and supported by the Australian National Health and Medical Research Council. At the time of submission of this paper 2,034 subjects have been recruited and the intervention delivered to 114 GPs. TRIAL REGISTRATION: Australia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12607000117415.

Rehabilitation interventions for foot drop in neuromuscular disease.

BACKGROUND: "Foot drop" or "Floppy foot drop" is the term commonly used to describe weakness or contracture of the muscles around the ankle joint. It may arise from many neuromuscular diseases. OBJECTIVES: To conduct a systematic review of randomised trials for the treatment of foot drop resulting from neuromuscular disease. SEARCH STRATEGY: In this update, we searched the Cochrane Neuromuscular Disease Group Trials Register (April 2009), MEDLINE (January 1966 to April 24 2009), EMBASE January 1980 to April 24 2009), CINAHL (January 1982 to May 6 2009), AMED (January 1985 to April 24 2009), the British Nursing Index (January 1985 to January 2008) and Royal College of Nursing Journal of Databases (January 1985 to January 2008). SELECTION CRITERIA: Randomised and quasi-randomised trials of physical, orthotic and surgical treatments for foot drop resulting from lower motor neuron or muscle disease and related contractures were included. People with primary joint disease were excluded. Interventions included a 'wait and see' approach, physiotherapy, orthoses, surgery and pharmacological therapy. The primary outcome measure was quantified ability to walk whilst secondary outcome measures included range of movement, dorsiflexor torque and strength, measures of activity and participation, quality of life and adverse effects. DATA COLLECTION AND ANALYSIS: Methodological quality was evaluated by two authors using the van Tulder criteria. Four studies with a total of n = 152 participants were included in the update to the original review. Heterogeneity of the studies precluded pooling the data. MAIN RESULTS: Early surgery did not significantly affect walking speed in a trial including 20 children with Duchenne muscular dystrophy. Both groups deteriorated during the 12 months follow-up. After one year, the mean difference (MD) of the 28 feet walking time was 0.00 seconds (95% confidence interval (CI) -0.83 to 0.83) and the MD of the 150 feet walking time was -2.88 seconds, favouring the control group (95% CI -8.18 to 2.42). Night splinting of the ankle did not significantly affect muscle force or range of movement about the ankle in a trial of 26 participants with Charcot-Marie-Tooth disease. Improvements were observed in both the splinting and control groups. In a trial of 26 participants with Charcot-Marie-Tooth disease and 28 participants with myotonic dystrophy, 24 weeks of strength training significantly improved six-metre timed walk in the Charcot-Marie-Tooth group compared to the control group (MD 0.70 seconds, favouring strength training, 95% CI 0.23 to 1.17), but not in the myotonic dystrophy group (MD -0.20 seconds, favouring the control group, 95% CI -0.79 to 0.39). No significant differences were observed for the 50 metre timed walk in the Charcot-Marie-Tooth disease group (MD 1.90 seconds, favouring the training group, 95% CI -0.29 to 4.09) or the myotonic dystrophy group (MD -0.80 seconds, favouring the control group, 95% CI -5.29 to 3.69). In a trial of 65 participants with facioscapulohumeral muscular dystrophy, 26 weeks of strength training did not significantly affect ankle strength. After one year, the mean difference in maximum voluntary isometric contraction was -0.43 kg, favouring the control group (95%CI -2.49 to 1.63) and the mean difference in dynamic strength was 0.44 kg, favouring the training group (95%CI -0.89 to 1.77). AUTHORS' CONCLUSIONS: Only one study, involving people with Charcot-Marie-Tooth disease, demonstrated a statistically significant positive effect of strength training. No effect of strength training was found in people with either myotonic dystrophy or facioscapulohumeral muscular dystrophy. Surgery had no significant effect in children with Duchenne muscular dystrophy and night splinting of the ankle had no significant effect in people with Charcot-Marie-Tooth disease. More evidence generated by methodologically sound trials is required.

Chronic condition self-management support: proposed competencies for medical students.

OBJECTIVE: Governments and the medical profession are concerned that there continues to be less than optimal health outcomes despite escalating expenditure on health services from the effect of the ageing population with chronic illnesses. In this context, doctors will need to have knowledge and skills in effective chronic condition management (CCM) and chronic condition self-management (CCSM). METHOD: A national workshop of representatives of eight medical schools from the CCSM special interest group (SIG) of the Australian and New Zealand Association on Medical Education met in September 2004, to consider curriculum content in CCM and CCSM. RESULTS: The workshop recommended that the Committee of Deans of Australian Medical Schools and the Commonwealth Department of Health and Ageing consider the identification and possible development of a specific curriculum for CCM and CCSM within the curricula of Australian Medical Schools. DISCUSSION: Consideration needs to be given to the changing nature of medical practice and that as part of this; doctors of the future will need skills in team participation, continuity of care, self-management support and patient-centered collaborative care planning. Doctors will also need skills to assist patients to better adhere to medical management, lifestyle behaviour change and risk factor reduction, if optimal health outcomes are to be achieved and costs are to be contained.

ICF Core Sets for low back pain.

OBJECTIVE: To report on the results of the consensus process integrating evidence from preliminary studies to develop the first version of a Comprehensive ICF Core Set and a Brief ICF Core Set for low back pain. METHODS: A formal decision-making and consensus process integrating evidence gathered from preliminary studies was followed. Preliminary studies included a Delphi exercise, a systematic review and an empirical data collection. After training in the ICF and based on these preliminary studies, relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preliminary studies identified a set of 503 ICF categories at the second, third and fourth ICF levels with 211 categories on body functions, 47 on body structures, 190 on activities and participation and 55 on environmental factors. Eighteen experts from 15 different countries attended the consensus conference on low back pain. Altogether 78 second-level categories were included in the Comprehensive ICF Core Set with 19 categories from the component body functions, 5 from body structures, 29 from activities and participation and 25 from environmental factors. The Brief ICF Core Set included a total of 35 second-level categories with 10 on body functions, 3 on body structures, 12 on activities and participation and 10 on environmental factors. CONCLUSION: A formal consensus process integrating evidence and expert opinion based on the ICF framework and classification led to the definition of ICF Core Sets for low back pain. Both the Comprehensive ICF Core Set and the Brief ICF Core Set were defined.

Shadows in the brain.

The aims of the present study were to investigate whether the processing of an object shadow occurs implicitly, that is without conscious awareness, and where physically within the human brain shadows are processed. Here we present neurological evidence, obtained from studies of brain-injured patients with visual neglect, that shadows are implicitly processed and that this processing may take place within the temporal lobe. Neglect patients with lesions that do not involve the right temporal lobe were still able to process shadows to optimize object shape perception. In contrast, shadow processing was not found to be as efficient in neglect patients with lesions that involve the right temporal lobe.

2: Rehabilitation of patients after stroke.

Stroke is the third highest cause of death and the leading cause of chronic disability in adults in Australia. Studies show clear advantages of treatment of patients in the acute phase of stroke in a dedicated stroke unit. Rehabilitation after stroke is a continuum, starting within days of stroke onset and ending only when it no longer produces any positive effect. More than half the 75% of patients who survive the first month after a stroke will require specialised rehabilitation. Effective rehabilitation relies on a coordinated, multidisciplinary team approach. Regular team meetings, as well as meetings with the patient, his or her family and carers, are essential. Improvements in function after stroke are the result of recovery within the ischaemic penumbra, resolution of cerebral oedema, neuroplasticity, and compensatory strategies learnt by the patient. Evidence supporting rehabilitation programs is based on evaluation of the multidisciplinary approach, or on the effect of a particular discipline (eg, speech therapy), rather than on individual components of treatment. When the patient is discharged from a formal rehabilitation program, the general practitioner's role becomes paramount. GPs can help patients deal with the consequences of stroke, such as depression, and any comorbidities. GPs may also provide counselling on issues ranging from interpersonal and sexual relationships, through ability to drive again, and vocational and recreational activities.

Diagnosis and treatment of obstructive sleep apnea in a stroke rehabilitation unit: a feasibility study.

Obstructive sleep apnea can be diagnosed in approximately 60% of stroke survivors in the postacute period and has been found to be associated with increased mortality and a worse functional outcome at 3 and 12 mo after discharge. In this study, 38 patients undergoing rehabilitation after stroke underwent sleep studies by using the AutoSet Portable II Plus device; obstructive sleep apnea was found in 18 of the patients, and five consecutively diagnosed patients were treated on the ward with nasal continuous positive airway pressure. The research has shown that it is feasible to routinely implement a diagnostic and therapeutic approach to sleep apnea on the rehabilitation ward, which is hoped to have a positive influence on mortality, functional outcome, and secondary prevention.

Early intervention for acute back injury: can we finally develop an evidence-based approach?

OBJECTIVE: Several reviews of the treatment of acute low back pain have been published in the past and have formed the basis of clinical guidelines. However, these lack consistency in some areas and valid data in others. As the literature in this field has continued to expand, the present review was undertaken to establish whether the guidelines in current use are supported by more recently published, scientifically rigorous research, and whether additional consensus regarding treatment of acute low back injury has been forthcoming in recent years. DESIGN: A review, and critical analysis, of literature relating to the treatment of acute low back pain that has been published since the production of the currently used clinical guidelines. The guidelines have been reviewed to assess whether their recommendations remain supportable. CONCLUSIONS: Recent research appears to support current clinical guidelines, i.e. exercise may have a positive effect while bed rest is ineffective and may be harmful, simple analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) have short-term benefits, and spinal manipulation may be effective in the first four weeks; no evidence was found for traction or back schools. However, we need more randomized controlled trials of treatments shown to be successful with the chronic population, e.g. focused on understanding psychological determinants, and using a multidisciplinary biopsychosocial approach. In the future this may help us to prevent acute low back progressing to the chronic state.
