Additional weekend therapy may reduce length of rehabilitation stay after stroke: a meta-analysis of individual patient data

QUESTIONS: Among people receiving inpatient rehabilitation after stroke, does additional weekend physiotherapy and/or occupational therapy reduce the length of rehabilitation hospital stay compared to those who receive a weekday-only service, and does this change after controlling for individual factors? Does additional weekend therapy improve the ability to walk and perform activities of daily living, measured at discharge? Does additional weekend therapy improve health-related quality of life, measured 6 months after discharge from rehabilitation? Which individual, clinical and hospital characteristics are associated with shorter length of rehabilitation hospital stay? DESIGN: This study pooled individual data from two randomised, controlled trials (n=350) using an individual patient data meta-analysis and multivariate regression. PARTICIPANTS: People with stroke admitted to inpatient rehabilitation facilities. INTERVENTION: Additional weekend therapy (physiotherapy and/or occupational therapy) compared to usual care (5 days/week therapy). OUTCOME MEASURES: Length of rehabilitation hospital stay, independence in activities of daily living measured with the Functional Independence Measure, walking speed and health-related quality of life. RESULTS: Participants who received weekend therapy had a shorter length of rehabilitation hospital stay. In the un-adjusted analysis, this was not statistically significant (MD -5.7 days, 95% CI -13.0 to 1.5). Controlling for hospital site, age, walking speed and Functional Independence Measure score on admission, receiving weekend therapy was significantly associated with a shorter length of rehabilitation hospital stay (β=7.5, 95% CI 1.7 to 13.4, p=0.001). There were no significant between-group differences in Functional Independence Measure scores (MD 1.9 points, 95% CI -2.8 to 6.6), walking speed (MD 0.06 m/second, 95% CI -0.15 to 0.04) or health-related quality of life (SMD -0.04, 95% CI -0.26 to 0.19) at discharge. DISCUSSION: Modest evidence indicates that additional weekend therapy might reduce rehabilitation hospital length of stay.

Exploring psychometric properties of the SF-6D, a preference-based health-related quality of life measure, in the context of spinal cord injury

PURPOSE: The validity of the SF-6D, a preference-based measure of health-related quality of life, is not well explored in the context of spinal cord injury (SCI). The aim of this analysis was to assess appropriate measurement properties of the SF-6D in a sample of individuals living with SCI. METHODS: Longitudinal data from the Rick Hansen Spinal Cord Injury Registry were used. Responses to the 36-item short-form health survey were transformed into SF-6D utility scores. We investigated practicality, floor and ceiling effects, and responsiveness to change. Responsiveness to change was explored using three different anchors that reflected changes in self-reported health, functional independence, and life satisfaction. Discriminative validity was assessed by ten a priori defined hypotheses, with a distinction made between 'strong' and 'weak' hypotheses. RESULTS: Three hundred and fifty-eight individuals with SCI were included in this analysis. Practicality was deemed acceptable based on a completion rate of 94%. The SF-6D showed low responsiveness to detect important health changes over time, and differences in responsiveness were found between individuals with paraplegia and tetraplegia. All five strong hypotheses and three weak hypotheses were confirmed. CONCLUSION: The SF-6D demonstrated good practicality and discriminative validity in this sample. The failure to detect self-reported and clinically important health changes requires further consideration. Comparative performance of the SF-6D (i.e., how the SF-6D performs against other preference-based measures) is unknown in the SCI context and requires further research.

Controlo postural na sequência de movimento de sentado para de pé em crianças com alterações do desenvolvimento neuromotor

A Sequência de Movimento de Sentado para de Pé (SMSP) é um marco importante na independência funcional da criança, sendo a sua qualidade afetada em casos de alteração do controlo postural do tronco. É por isso motivo de especial foco neste estudo, como elemento avaliativo e interventivo. Este estudo tem como objetivo a análise da modificação de componentes motores relacionados com o controlo postural, durante a SMSP, em 5 crianças com alterações neuromotoras, face à aplicação de um programa de intervenção baseado no Tratamento de Neuro Desenvolvimento (TND). Foi para tal utilizada a análise cinemática da SMSP - nomeadamente as variáveis “variação do deslocamento dos segmentos cabeça e tronco” e “variação do ângulo perna-pé” entre o momento inicial e o seat-off – complementada com a aplicação do Teste de Medida da Função Motora 88 (TMFM-88) e a Classificação Internacional da Funcionalidade Incapacidade e Saúde-Versão Crianças e Jovens (CIF-CJ), bem como a avaliação de componentes de movimento com recurso a registo de imagem. A análise cinemática demonstrou uma diminuição do deslocamento dos segmentos cabeça e tronco na maioria dos casos, bem como uma maior mobilidade da tíbia sobre pé. Verificou-se um aumento do score final do TMFM-88, em todos os casos. A CIF-CJ não evidenciou alterações entre o início e o término do período de intervenção. O registo de imagem demonstrou alterações positivas visíveis no alinhamento de segmentos, nível de atividade, controlo postural, e recurso a estratégias compensatórias no conjunto postural sentado e na SMSP. Após o período de intervenção as crianças deste estudo evidenciaram modificações positivas nas variáveis em estudo, nomeadamente 1) diminuição do deslocamento dos segmentos cabeça e tronco na fase inicial da SMSP, 2) aumento da variação do ângulo perna-pé na fase inicial da SMSP, 3) aumento do score total da TMFM-88, 4) alteração positiva dos componentes de movimento alinhamento de segmentos e nível de atividade e 5) redução do recurso a estratégias compensatórias de movimento na SMSP. Estas modificações sugerem um controlo postural mais eficiente.

Influence of dual-task on sit-to-stand-to-sit postural control in Parkinson's disease

Postural control deficits are the most disabling aspects of Parkinson's disease (PD), resulting in decreased mobility and functional independence. The aim of this study was to assess the postural control stability, revealed by variables based on the centre of pressure (CoP), in individuals with PD while performing a sit-to-stand-to-sit sequence under single- and dual-task conditions. An observational, analytical and cross-sectional study was performed. The sample consisted of 9 individuals with PD and 9 healthy controls. A force platform was used to measure the CoP displacement and velocity during the sit-to-stand-to-sit sequence. The results were statistically analysed. Individuals with PD required greater durations for the sit-to-stand-to-sit sequence than the controls (p < 0.05). The anteroposterior and mediolateral CoP displacement were higher in the individuals with PD (p < 0.05). However, only the anteroposterior CoP velocity in the stand-to-sit phase (p = 0.006) was lower in the same individuals. Comparing the single- and dual-task conditions in both groups, the duration, the anteroposterior CoP displacement and velocity were higher in the dual-task condition (p < 0.05). The individuals with PD presented reduced postural control stability during the sit-to-stand-to-sit sequence, especially when under the dual-task condition. These individuals have deficits not only in motor performance, but also in cognitive performance when performing the sit-to-stand-to-sit sequence in their daily life tasks. Moreover, both deficits tend to be intensified when two tasks are performed simultaneously.

Is rehabilitation associated with change in functional status among nursing home residents?

Assessing functional status of residents in nursing homes is one way to evaluate the quality of care provided. The purpose of this study was to investigate whether rehabilitation interventions could lead to improved functional independence. A prospective study was carried out to examine the change in activities of daily living (ADL) of 310 residents aged 65 or above over a period of 6 months. About 41.3% (n = 128) received rehabilitation therapy. Functional improvement was observed in 30.6% of the participants. The corresponding figures for stabilization and functional decline were 45.2% and 24.2%, respectively. Using a multinomial logistic regression, we found that factors significantly associated with change in functional status included baseline ADL score, family visit, number of beds in the institution, and transfer to acute hospitals. After adjusting for these confounding variables, change in functional status of those who received rehabilitation and those who did not was not significantly different.

Assessment of functional capacity of the elderly associated with the risk for pressure ulcer

OBJECTIVE: To characterize the elderly with physical limitations; to assess functional capacity as it relates to physical mobility, cognitive status and level of functional independence in activities of daily living, and to relate functional capacity to the risk for pressure ulcers. METHODS: A quantitative cross-sectional approach, conducted in households in the city of João Pessoa (PB) with seniors who presented physical limitation. Fifty-one elderly were investigated in a two-stage cluster sampling design. RESULTS: There was evidence of impairments in functional capacity of the elderly aged 80 years or more, with more severe physical limitations, cognitive impairment and a higher level of dependency for activities. Significant differences were observed between the level of functional independence in performing activities of daily living and the risk of pressure ulcers. CONCLUSION: This study allowed for the identification of the elderly in functional decline and at risk for developing pressure ulcers, supporting the implementation of preventive actions at the household level.

MEETING THE NEEDS OF HANDICAPPED CHILDREN: A STUDY OF EDUCATIONAL AND HEALTH CARE SERVICES PROVIDED TO PRE-KINDERGARTEN CHILDREN IN THE HOUSTON INDEPENDENT SCHOOL DISTRICT EARLY CHILDHOOD PROGRAM FOR THE HANDICAPPED (PARENT SATISFACTION, FUNCTIONAL STATUS, PSYCHOSOCIAL DEVELOPMENT)

The Education for All Handicapped Children Act of 1975, P.L. 94-142, created a new challenge for the nation's public school systems. During 1982-1983, a national study, called the "Collaborative Study of Children with Special Needs", was conducted in 5 metropolitan school districts to evaluate the effectiveness of education and health care services of children in kindergarten to 6th grade being provided under P.L. 94-142 programs. This dissertation (the Substudy) was undertaken to augment the findings of the Collaborative Study. The purpose of this study was to develop a database to provide descriptive information on the demographic, service and health characteristics of a small group of 3 and 4 year old handicapped children served by the Houston Independent School District (HISD) during 1982-1983.^ The study involved a stratified sample of 105 three and four year old children divided into 3 groups according to type of handicapping condition.^ The results of the study gave a clearer picture of the demographic characteristics of these Pre-K children. Specifically, sex ratio was approximately one, lower than the national norm. Family and socioeconomic characteristics were assessed.^ The study used an independence/dependence index composed of 11 items on the parent questionnaire to assess the level of functional independence of each child. An association was found between index scores and parent-reported effects of the child on family activity. Parents who said that their child's condition had affected the family's job situation, housing accomodations, vacation plans, marriage, choice of friends and social activities were also more likely to report less independence in the child. In addition, many of the Substudy children had extensive care-taking needs reflected in specific components of the index such as dressing, feeding, toileting or moving about the house.^ In general the results of the Pre-K Substudy indicate that at the early childhood level, the HISD special education program is functioning well in most areas and that parents are very satisfied with the program.

Genetic definition of a protein-splicing domain: Functional mini-inteins support structure predictions and a model for intein evolution

Inteins are protein-splicing elements, most of which contain conserved sequence blocks that define a family of homing endonucleases. Like group I introns that encode such endonucleases, inteins are mobile genetic elements. Recent crystallography and computer modeling studies suggest that inteins consist of two structural domains that correspond to the endonuclease and the protein-splicing elements. To determine whether the bipartite structure of inteins is mirrored by the functional independence of the protein-splicing domain, the entire endonuclease component was deleted from the Mycobacterium tuberculosis recA intein. Guided by computer modeling studies, and taking advantage of genetic systems designed to monitor intein function, the 440-aa Mtu recA intein was reduced to a functional mini-intein of 137 aa. The accuracy of splicing of several mini-inteins was verified. This work not only substantiates structure predictions for intein function but also supports the hypothesis that, like group I introns, mobile inteins arose by an endonuclease gene invading a sequence encoding a small, functional splicing element.

Determinantes da incapacidade funcional em doentes com AVC

Introdução- O Acidente Vascular Cerebral continua a ser a primeira causa de morte em Portugal, sendo também responsável pelo elevado índice de incapacidade e dependência funcional da população adulta portuguesa, afetando significativamente os aspetos da vida física, económica e social. Os processos de reabilitação continuados têm-se mostrado bastante eficazes na recuperação da independência funcional destes doentes. Assim sendo o objetivo geral deste estudo consiste em avaliar o nível de independência funcional e os fatores determinantes nesses níveis, em doentes sujeitos a programas de reabilitação continuados e doentes sem reabilitação. Métodos- O presente estudo é de carácter quantitativo, enquadrando-se num desenho de estudo descritivo transversal e analítico, no qual participaram 60 indivíduos que sofreram AVC, pertencendo 36 ao grupo experimental e 24 ao grupo de controle. A recolha de dados foi efetuada através de um questionário composto por questões de caracterização sociodemográfica, de caracterização clinica, uma escala de APGAR Familiar e uma Escala de Medida de Independência funcional (MIF). Resultados- A análise por grupos mostra que o grupo experimental é mais independente que o grupo de controle, ou seja, o nível de independência funcional é mais elevado na sua generalidade na amostra de indivíduos sujeitos a processos de reabilitação. As variáveis que influenciaram significativamente a independência funcional foram: o género (no comportamento social no G.cont),o estado civil (solteiros/viúvo mais independentes aos níveis dos cuidados pessoais, controle dos esfíncteres, mobilidade e locomoção no G. exp), habilitações académicas (maior escolaridade maior independência no G. exp) fatores de risco (doentes sem fatores de risco no G. cont são mais independentes nos cuidados pessoais, controle de esfíncteres e locomoção), indivíduos com AVC isquémico são mais independentes nos cuidados pessoais e locomoção, e os que realizaram trombólise são mais independentes nas diferentes dimensões nos dois grupos. Conclusão- As variáveis sociodemográficas e clinicas exercem influência apenas em algumas dimensões da independência funcional dos utentes após o AVC e a reabilitação desenvolvida de forma continuada, aumenta o grau de independência dos doentes diminuindo o grau de incapacidade. Palavras-chave- Acidente Vascular Cerebral, Incapacidade, Independência Funcional, Reabilitação.

Predicting fitness for chemotherapy in older cancer patients

Background: The Vulnerable Elders Survey-13 (VES-13) is increasingly used to screen for older patients who can proceed to intensive chemotherapy without further comprehensive assessment. This study compared the VES-13 determination of fitness for treatment with the oncologist's assessments of fitness. Method: Sample: Consecutive series of solid tumour patients ≥65 years (n=175; M=72; range=65-86) from an Australian cancer centre. Patients were screened with the VES-13 before proceeding to usual treatment. Blinded to screening, oncologists concurrently predicted patient fitness for chemotherapy. A sample of 175 can detect, with 90% power, kappa coefficients of agreement between VES-13 and oncologists’ assessments >0.90 ("almost perfect agreement"). Separate backward stepwise logistic regression analyses assessed potential predictors of VES-13 and oncologists’ ratings of fitness. Results: Kappa coefficient for agreement between VES-13 and oncologists’ ratings of fitness was 0.41 (p<0.001). VES-13 and oncologists’ assessments agreed in 71% of ratings. VES-13 sensitivity = 83.3%; specificity = 57%; positive predictive value = 69%; negative predictive value = 75%. Logistic regression modelling indicated that the odds of being vulnerable to chemotherapy (VES-13) increased with increasing depression (OR=1.42; 95% CI: 1.18, 1.71) and decreased with increased functional independence assessed on the Bartel Index (OR=0.82; CI: 0.74, 0.92) and Lawton instrumental activities of daily living (OR=0.44; CI: 0.30, 0.65); RSquare=.65. Similarly, the odds of a patient being vulnerable to chemotherapy, when assessed by physicians, increased with increasing age (OR=1.15; CI: 1.07, 1.23) and depression (OR=1.23; CI: 1.06, 1.43), and decreased with increasing functional independence (OR=0.91; CI: 0.85, 0.98); RSquare=.32. Conclusions: Our data indicate moderate agreement between VES-13 and clinician assessments of patients’ fitness for chemotherapy. Current ‘one-step’ screening processes to determine fitness have limits. Nonetheless, screening tools do have the potential for modification and enhanced predictive properties in cancer care by adding relevant items, thus enabling fit patients to be immediately referred for chemotherapy.

Encouraging, assisting, and time to eat : comparison of mealtime assistance interventions in elderly medical inpatients

BACKGROUND: The prevalence of protein-energy malnutrition in older adults is reported to be as high as 60% and is associated with poor health outcomes. Inadequate feeding assistance and mealtime interruptions may contribute to malnutrition and poor nutritional intake during hospitalisation. Despite being widely implemented in practice in the United Kingdom and increasingly in Australia, there have been few studies examining the impact of strategies such as Protected Mealtimes and dedicated feeding assistant roles on nutritional outcomes of elderly inpatients. AIMS: The aim of this research was to implement and compare three system-level interventions designed to specifically address mealtime barriers and improve energy intakes of medical inpatients aged ≥65 years. This research also aimed to evaluate the sustainability of any changes to mealtime routines six months post-intervention and to gain an understanding of staff perceptions of the post-intervention mealtime experience. METHODS: Three mealtime assistance interventions were implemented in three medical wards at Royal Brisbane and Women's Hospital: AIN-only: Additional assistant-in-nursing (AIN) with dedicated nutrition role. PM-only: Multidisciplinary approach to meals, including Protected Mealtimes. PM+AIN: Combined intervention: AIN + multidisciplinary approach to meals. An action research approach was used to carefully design and implement the three interventions in partnership with ward staff and managers. Significant time was spent in consultation with staff throughout the implementation period to facilitate ownership of the interventions and increase likelihood of successful implementation. A pre-post design was used to compare the implementation and nutritional outcomes of each intervention to a pre-intervention group. Using the same wards, eligible participants (medical inpatients aged ≥65 years) were recruited to the preintervention group between November 2007 and March 2008 and to the intervention groups between January and June 2009. The primary nutritional outcome was daily energy and protein intake, which was determined by visually estimating plate waste at each meal and mid-meal on Day 4 of admission. Energy and protein intakes were compared between the pre and post intervention groups. Data were collected on a range of covariates (demographics, nutritional status and known risk factors for poor food intake), which allowed for multivariate analysis of the impact of the interventions on nutritional intake. The provision of mealtime assistance to participants and activities of ward staff (including mealtime interruptions) were observed in the pre-intervention and intervention groups, with staff observations repeated six months post-intervention. Focus groups were conducted with nursing and allied health staff in June 2009 to explore their attitudes and behaviours in response to the three mealtime interventions. These focus group discussions were analysed using thematic analysis. RESULTS: A total of 254 participants were recruited to the study (pre-intervention: n=115, AIN-only: n=58, PM-only: n=39, PM+AIN: n=42). Participants had a mean age of 80 years (SD 8), and 40% (n=101) were malnourished on hospital admission, 50% (n=108) had anorexia and 38% (n=97) required some assistance at mealtimes. Occasions of mealtime assistance significantly increased in all interventions (p<0.01). However, no change was seen in mealtime interruptions. No significant difference was seen in mean total energy and protein intake between the preintervention and intervention groups. However, when total kilojoule intake was compared with estimated requirements at the individual level, participants in the intervention groups were more likely to achieve adequate energy intake (OR=3.4, p=0.01), with no difference noted between interventions (p=0.29). Despite small improvements in nutritional adequacy, the majority of participants in the intervention groups (76%, n=103) had inadequate energy intakes to meet their estimated energy requirements. Patients with cognitive impairment or feeding dependency appeared to gain substantial benefit from mealtime assistance interventions. The increase in occasions of mealtime assistance by nursing staff during the intervention period was maintained six-months post-intervention. Staff focus groups highlighted the importance of clearly designating and defining mealtime responsibilities in order to provide adequate mealtime care. While the purpose of the dedicated feeding assistant was to increase levels of mealtime assistance, staff indicated that responsibility for mealtime duties may have merely shifted from nursing staff to the assistant. Implementing the multidisciplinary interventions empowered nursing staff to "protect" the mealtime from external interruptions, but further work is required to empower nurses to prioritise mealtime activities within their own work schedules. Staff reported an increase in the profile of nutritional care on all wards, with additional non-nutritional benefits noted including improved mobility and functional independence, and better identification of swallowing difficulties. IMPLICATIONS: The PhD research provides clinicians with practical strategies to immediately introduce change to deliver better mealtime care in the hospital setting, and, as such, has initiated local and state-wide roll-out of mealtime assistance programs. Improved nutritional intakes of elderly inpatients was observed; however given the modest effect size and reducing lengths of hospital stays, better nutritional outcomes may be achieved by targeting the hospital-to-home transition period. Findings from this study suggest that mealtime assistance interventions for elderly inpatients with cognitive impairment and/or functional dependency show promise.

Social work and complex care systems: The case of people hospitalised with a disability

Health and hospital system reforms prioritise efficiency. However, initiatives can impact on people with new or existing disabilities who require time to maximise functional independence. With greater demands for shorter hospital stays social workers face increasing pressure to facilitate discharge. This paper reports findings from research identifying factors contributing to extended stays for adults with disabilities. We sought to better understand patient characteristics and discharge planning challenges by analysing a clinical data set of 80 patients and qualitative interviews with five experienced hospital social workers. Three key factors are identified: issues around rehabilitation services; assessment and planning for community care; and availability of and access to discharge options. Strategies to reduce length of stay are reported. We argue that building collaborative partnerships and working across multiple, complex systems and disciplines are vital to ensure these patients access appropriate community-based resources within the current health reform environment.
