ABSTRACT
BACKGROUND: Poor outcomes and high resource-use are observed for frail older people discharged from acute medical units. A specialist geriatric medical intervention, to facilitate Comprehensive Geriatric Assessment, was developed to reduce the incidence of adverse outcomes and associated high resource-use in this group in the post-discharge period. OBJECTIVE: To examine the costs and cost-effectiveness of a specialist geriatric medical intervention for frail older people in the 90 days following discharge from an acute medical unit, compared with standard care. METHODS: Economic evaluation was conducted alongside a two-centre randomised controlled trial (AMIGOS). 433 patients (aged 70 or over) at risk of future health problems, discharged from acute medical units within 72 hours of attending hospital, were recruited in two general hospitals in Nottingham and Leicester, UK. Participants were randomised to the intervention, comprising geriatrician assessment in acute units and further specialist management, or to control where patients received no additional intervention over and above standard care. Primary outcome was incremental cost per quality adjusted life year (QALY) gained. RESULTS: We undertook cost-effectiveness analysis for 417 patients (intervention: 205). The difference in mean adjusted QALYs gained between groups at 3 months was -0.001 (95% confidence interval [CI]: -0.009, 0.007). Total adjusted secondary and social care costs, including direct costs of the intervention, at 3 months were £4412 (5624, $6878) and £4110 (5239, $6408) for the intervention and standard care groups, the incremental cost was £302 (95% CI: 193, 410) [385, $471]. The intervention was dominated by standard care with probability of 62%, and with 0% probability of cost-effectiveness (at £20,000/QALY threshold). CONCLUSIONS: The specialist geriatric medical intervention for frail older people discharged from acute medical unit was not cost-effective. Further research on designing effective and cost-effective specialist service for frail older people discharged from acute medical units is needed.

BACKGROUND: acute medical units allow for those who need admission to be correctly identified, and for those who could be managed in ambulatory settings to be discharged. However, re-admission rates for older people following discharge from acute medical units are high and may be associated with substantial health and social care costs. OBJECTIVE: identifying patient-level health and social care costs for older people discharged from acute medical units in England. DESIGN: a prospective cohort study of health and social care resource use. SETTING: an acute medical unit in Nottingham, England. PARTICIPANTS: four hundred and fifty-six people aged over 70 who were discharged from an acute medical unit within 72 h of admission. METHODS: hospitalisation and social care data were collected for 3 months post-recruitment. In Nottingham, further approvals were gained to obtain data from general practices, ambulance services, intermediate care and mental healthcare. Resource use was combined with national unit costs. RESULTS: costs from all sectors were available for 250 participants. The mean (95% CI, median, range) total cost was £1926 (1579-2383, 659, 0-23,612). Contribution was: secondary care (76.1%), primary care (10.9%), ambulance service (0.7%), intermediate care (0.2%), mental healthcare (2.1%) and social care (10.0%). The costliest 10% of participants accounted for 50% of the cost. CONCLUSIONS: this study highlights the costs accrued by older people discharged from acute medical units (AMUs): they are mainly (76%) in secondary care and half of all costs were incurred by a minority of participants (10%).

OBJECTIVE: To evaluate the effect of specialist geriatric medical management on the outcomes of at risk older people discharged from acute medical assessment units. DESIGN: Individual patient randomised controlled trial comparing intervention with usual care. SETTING: Two hospitals in Nottingham and Leicester, UK. PARTICIPANTS: 433 patients aged 70 or over who were discharged within 72 hours of attending an acute medical assessment unit and at risk of decline as indicated by a score of at least 2 on the Identification of Seniors At Risk tool. INTERVENTION: Assessment made on the acute medical assessment unit and further outpatient management by specialist physicians in geriatric medicine, including advice and support to primary care services. MAIN OUTCOME MEASURES: The primary outcome was the number of days spent at home (for those admitted from home) or days spent in the same care home (if admitted from a care home) in the 90 days after randomisation. Secondary outcomes were determined at 90 days and included mortality, institutionalisation, dependency, mental wellbeing, quality of life, and health and social care resource use. RESULTS: The two groups were well matched for baseline characteristics, and withdrawal rates were similar in both groups (5%). Mean days at home over 90 days' follow-up were 80.2 days in the control group and 79.7 in the intervention group. The 95% confidence interval for the difference in means was -4.6 to 3.6 days (P=0.31). No significant differences were found for any of the secondary outcomes. CONCLUSIONS: This specialist geriatric medical intervention applied to an at risk population of older people attending and being discharged from acute medical units had no effect on patients' outcomes or subsequent use of secondary care or long term care.

BACKGROUND: tools are required to identify high-risk older people in acute emergency settings so that appropriate services can be directed towards them. OBJECTIVE: to evaluate whether the Identification of Seniors At Risk (ISAR) predicts the clinical outcomes and health and social services costs of older people discharged from acute medical units. DESIGN: an observational cohort study using receiver-operator curve analysis to compare baseline ISAR to an adverse clinical outcome at 90 days (where an adverse outcome was any of death, institutionalisation, hospital readmission, increased dependency in activities of daily living (decrease of 2 or more points on the Barthel ADL Index), reduced mental well-being (increase of 2 or more points on the 12-point General Health Questionnaire) or reduced quality of life (reduction in the EuroQol-5D) and high health and social services costs over 90 days estimated from routine electronic service records. SETTING: two acute medical units in the East Midlands, UK. PARTICIPANTS: a total of 667 patients aged ≥70 discharged from acute medical units. RESULTS: an adverse outcome at 90 days was observed in 76% of participants. The ISAR was poor at predicting adverse outcomes (AUC: 0.60, 95% CI: 0.54-0.65) and fair for health and social care costs (AUC: 0.70, 95% CI: 0.59-0.81). CONCLUSIONS: adverse outcomes are common in older people discharged from acute medical units in the UK; the poor predictive ability of the ISAR in older people discharged from acute medical units makes it unsuitable as a sole tool in clinical decision-making.

BACKGROUND: older people are at an increased risk of adverse outcomes following attendance at acute hospitals. Screening tools may help identify those most at risk. The objective of this study was to compare the predictive properties of five frailty-rating scales. METHOD: this was a secondary analysis of a cohort study involving participants aged 70 years and above attending two acute medical units in the East Midlands, UK. Participants were classified at baseline as frail or non-frail using five different frailty-rating scales. The ability of each scale to predict outcomes at 90 days (mortality, readmissions, institutionalisation, functional decline and a composite adverse outcome) was assessed using area under a receiver-operating characteristic curve (AUC). RESULTS: six hundred and sixty-seven participants were studied. Frail participants according to all scales were associated with a significant increased risk of mortality [relative risk (RR) range 1.6-3.1], readmission (RR range 1.1-1.6), functional decline (RR range 1.2-2.1) and the composite adverse outcome (RR range 1.2-1.6). However, the predictive properties of the frailty-rating scales were poor, at best, for all outcomes assessed (AUC ranging from 0.44 to 0.69). CONCLUSION: frailty-rating scales alone are of limited use in risk stratifying older people being discharged from acute medical units.

OBJECTIVE: To investigate two approaches to treating patients with persistent dressing problems and cognitive difficulties following stroke. DESIGN: Pilot randomized controlled trial. SETTING: Inpatient stroke rehabilitation service. SUBJECTS: Seventy consecutive stroke patients with persistent dressing problems and accompanying cognitive difficulties at two weeks after their stroke. INTERVENTIONS: Patients were randomly allocated to six weeks of either a systematic neuropsychological approach, based on analysis of dressing problems and further cognitive testing, or to the control group who received conventional (functional) dressing practice. Both groups received treatment three times a week in accordance with two separately prepared manuals. MAIN MEASURES: Nottingham Stroke Dressing Assessment (NSDA), Line Cancellation, 10-hole peg transfer test, Object Decision, Gesture Imitation. Patients were assessed at six weeks after randomization by an independent assessor masked to group allocation. RESULTS: Both neuropsychological and functional groups improved performance on the NSDA over the treatment period (31% and 22%, respectively) but there was no significant difference between groups at six weeks. However, the neuropsychological group showed a significantly greater improvement on a line cancellation test of visual neglect (t(62) = 2.1, P < 0.05) and a planned subanalysis for those with right hemisphere damage showed a trend towards better dressing outcome (P = 0.07, one-tailed). CONCLUSIONS: Results demonstrate the potential benefits of a systematic neuropsychological approach to dressing therapy, particularly for patients with right hemisphere damage. This study suggests the need for a phase III study evaluating the efficacy of a systematic neuropsychological approach in treating dressing difficulties, targeting patients with right hemisphere stroke and visuospatial impairments.

BACKGROUND: Many older people presenting to Acute Medical Units (AMU) are discharged after only a short stay (< 72 hours), yet many re-present to hospital or die within 1 year. Comprehensive Geriatric Assessment may improve patient outcomes for this group. PARTICIPANTS: Patients aged > 70 years and scoring positive on a risk screening tool ('Identification of Seniors At Risk') who are discharged within 72 hours of attending an AMU with a medical crisis, recruited prior to discharge. Sample size is 400. Carers of participants will also be recruited. INTERVENTION: Assessment on the AMU and further out-patient management by a specialist physician in geriatric medicine. Assessment and further management will follow the principles of Comprehensive Geriatric Assessment, providing advice and support to primary care services. DESIGN: Multi-centre, individual patient randomised controlled trial comparing intervention with usual care. OUTCOME MEASUREMENT: Follow up is by postal questionnaire 90 days after randomisation, and data will be entered into the study database by a researcher blind to allocation. The primary outcome is the number of days spent at home (for those admitted from home), or days spent in the same care home (if admitted from a care home). Secondary outcomes include mortality, institutionalisation, health and social care resource use, and scaled outcome measures, including quality of life, disability, mental well-being. Carer strain and well being will also be measured at 90 days. ANALYSES: Comparisons of outcomes and costs, and a cost utility analysis between the intervention and control groups will be carried out. TRIAL REGISTRATION: ISRCTN: ISRCTN21800480.

BACKGROUND: Stroke rehabilitation is a complex intervention. Many factors influence the interaction between the patient and the elements of the intervention. Rehabilitation interventions are aimed at altering different domains of patient outcome including body functions, activity and participation. As a consequence, randomised clinical trials in this area are difficult to design. We developed an archive of stroke rehabilitation trials (VISTA-Rehab) to act as a resource to help trialists model and design future rehabilitation studies. METHODS: We developed specific eligibility criteria for the entry of stroke rehabilitation trials into the archive. We established a Steering Committee to oversee projects and publications and commenced the recruitment of rehabilitation trials into this resource. RESULTS: As of August 2009, VISTA-Rehab contains data from 23 stroke rehabilitation trials (>3400 patients). Demographic data, including age [median=73, interquartile range (63,79)], gender (male=53%) and initial dependency [median baseline Barthel index score=6, interquartile range (9,19)], are available for all patients. Outcome measures include the modified Rankin Scale, Barthel Index, Rivermead Motor Assessment, Fugl-Meyer Assessment, General Health Questionnaire and Nottingham Extended Activities of Daily Living Scale. CONCLUSION: VISTA-Rehab expands the Virtual International Stroke Trials Archive to include rehabilitation trials. Anonymised data can be used to examine questions specific to stroke rehabilitation and to generate novel hypotheses.

OBJECTIVE: to determine the clinical effectiveness of a day hospital-delivered multifactorial falls prevention programme, for community-dwelling older people at high risk of future falls identified through a screening process. DESIGN: multicentre randomised controlled trial. SETTING: eight general practices and three day hospitals based in the East Midlands, UK. PARTICIPANTS: three hundred and sixty-four participants, mean age 79 years, with a median of three falls risk factors per person at baseline. INTERVENTIONS: a day hospital-delivered multifactorial falls prevention programme, consisting of strength and balance training, a medical review and a home hazards assessment. MAIN OUTCOME MEASURE: rate of falls over 12 months of follow-up, recorded using self-completed monthly diaries. RESULTS: one hundred and seventy-two participants in each arm contributed to the primary outcome analysis. The overall falls rate during follow-up was 1.7 falls per person-year in the intervention arm compared with 2.0 falls per person-year in the control arm. The stratum-adjusted incidence rate ratio was 0.86 (95% CI 0.73-1.01), P = 0.08, and 0.73 (95% CI 0.51-1.03), P = 0.07 when adjusted for baseline characteristics. There were no significant differences between the intervention and control arms in any secondary outcomes. CONCLUSION: this trial did not conclusively demonstrate the benefit of a day hospital-delivered multifactorial falls prevention programme, in a population of older people identified as being at high risk of a future fall.

BACKGROUND AND PURPOSE: We describe our attempts to evaluate the effectiveness of a virtual environment developed to rehabilitate stroke patients in the task of making a hot drink. METHODS: Single case studies were performed in 13/138 (9%) stroke patients undergoing rehabilitation in a UK stroke unit. Participants in AB/BA (n = 5) and ABA (n = 2) design studies received 5 one-hour sessions of attention control training (A phase) and 5 one-hour sessions of virtual environment training (B phase). An AB design with random duration of A and B phases (minimum duration of A and B phases 3 and 5 days respectively, with total duration of 3 weeks) was used in 6 participants. RESULTS: Visual inspection of scores across all cases showed a trend towards improvement over time in both real and virtual hot drink making ability in both control and intervention phases. There was no significant difference (Wilcoxon, p > 0.05) in the improvements in real and virtual hot drink making ability during all control and intervention phases in the 13 cases. Ceiling effects limited the evaluation of effectiveness in 5 of the 8 cases in which daily performance measures were used. CONCLUSIONS: Few people in this setting were suitable for this intervention. The case studies showed no evidence of a strong effect of this intervention, but we had great difficulty in performing single case studies. We conclude that more testing and development of this system is required before it is subjected to rigorous testing of clinical effectiveness.

OBJECTIVE: To determine whether occupational therapy focused specifically on personal activities of daily living improves recovery for patients after stroke. DESIGN: Systematic review and meta-analysis. DATA SOURCES: The Cochrane stroke group trials register, the Cochrane central register of controlled trials, Medline, Embase, CINAHL, PsycLIT, AMED, Wilson Social Sciences Abstracts, Science Citation Index, Social Science Citation, Arts and Humanities Citation Index, Dissertations Abstracts register, Occupational Therapy Research Index, scanning reference lists, personal communication with authors, and hand searching. REVIEW METHODS: Trials were included if they evaluated the effect of occupational therapy focused on practice of personal activities of daily living or where performance in such activities was the target of the occupational therapy intervention in a stroke population. Original data were sought from trialists. Two reviewers independently reviewed each trial for methodological quality. Disagreements were resolved by consensus. RESULTS: Nine randomised controlled trials including 1258 participants met the inclusion criteria. Occupational therapy delivered to patients after stroke and targeted towards personal activities of daily living increased performance scores (standardised mean difference 0.18, 95% confidence interval 0.04 to 0.32, P=0.01) and reduced the risk of poor outcome (death, deterioration or dependency in personal activities of daily living) (odds ratio 0.67, 95% confidence interval 0.51 to 0.87, P=0.003). For every 100 people who received occupational therapy focused on personal activities of daily living, 11 (95% confidence interval 7 to 30) would be spared a poor outcome. CONCLUSIONS: Occupational therapy focused on improving personal activities of daily living after stroke can improve performance and reduce the risk of deterioration in these abilities. Focused occupational therapy should be available to everyone who has had a stroke.

BACKGROUND AND PURPOSE: Virtual environments for use in stroke rehabilitation are in development, but there has been little evaluation of their suitability for this purpose. We evaluated a virtual environment developed for the rehabilitation of the task of making a hot drink. METHODS: Fifty stroke patients undergoing rehabilitation in a UK hospital stroke unit were involved. The performance of stroke rehabilitation patients when making a hot drink had the neurological impairments associated with performance of this task, and the errors observed were compared for standardized task performance in the real world and in a virtual environment. Neurological impairments were measured using standardized assessments. Errors in task performance were assessed rating video recordings and classified into error types. RESULTS: Real-world and virtual environment performance scores were not strongly associated (rho=0.30; P<0.05). Performance scores in both settings were associated with age, Barthel ADL score, Mini Mental State Examination score, and tests of visuospatial function. Real-world performance only was associated with arm function and sequencing ability. Virtual environment performance only was associated with language function and praxis. Participants made different errors during task performance in the real world and in the virtual environment. CONCLUSIONS: Although this virtual environment was usable by stroke rehabilitation patients, it posed a different rehabilitation challenge from the task it was intended to simulate, and so it might not be as effective as intended as a rehabilitation tool. Other virtual environments for stroke rehabilitation in development require similar evaluation.
