Randomized trial of a population-based, home-delivered intervention for preschool language delay

OBJECTIVE: iv>Population approaches to lessen the adverse impacts of preschool language delay remain elusive. We aimed to determine whether systematic ascertainment of language delay at age 4 years, followed by a 10-month, 1-on-1 intervention, improves language and related outcomes at age 5 years.

METHODS:
A randomized trial nested within a cross-sectional ascertainment of language delay. Children with expressive and/or receptive language scores more than 1.25 SD below the mean at age 4 years entered the trial. Children randomly allocated to the intervention received 18 1-hour home-based therapy sessions. The primary outcomes were receptive and expressive language (Clinical Evaluation of Language Fundamentals – Preschool, 2nd Edition) and secondary outcomes were child phonological skills, letter awareness, pragmatic skills, behavior, and quality of life.

RESULTS:
A total of 1464 children were assessed for language delay at age 4 years. Of 266 eligible children, 200 (13.6%) entered the trial, with 91 intervention (92% of 99) and 88 control (87% of 101) children retained at age 5 years. At age 5 years, there was weak evidence of benefit to expressive (adjusted mean difference, intervention − control, 2.0; 95% confidence interval [CI] −0.5 to 4.4; P = .12) but not receptive (0.6; 95% CI −2.5 to 3.8; P = .69) language. The intervention improved phonological awareness skills (5.0; 95% CI 2.2 to 7.8; P < .001) and letter knowledge (2.4; 95% CI 0.3 to 4.5; P = .03), but not other secondary outcomes.

CONCLUSIONS:
A standardized yet flexible 18-session language intervention was successfully delivered by non-specialist staff, found to be acceptable and feasible, and has the potential to improve long-term consequences of early language delay within a public health framework.iv>

Two-year outcomes of a population-based intervention for preschool language delay : an RCT

OBJECTIVE: We have previously shown short-term benefits to phonology, letter knowledge, and possibly expressive language from systematically ascertaining language delay at age 4 years followed by the Language for Learning intervention. Here, we report the trial's definitive 6-year outcomes. METHODS: Randomized trial nested in a population-based ascertainment. Children with language scores >1.25 SD below the mean at age 4 were randomized, with intervention children receiving 18 1-hour home-based therapy sessions. Primary outcome was receptive/expressive language. Secondary outcomes were phonological, receptive vocabulary, literacy, and narrative skills; parent-reported pragmatic language, behavior, and health-related quality of life; costs of intervention; and health service use. For intention-to-treat analyses, trial arms were compared using linear regression models. RESULTS: Of 1464 children assessed at age 4, 266 were eligible and 200 randomized; 90% and 82% of intervention and control children were retained respectively. By age 6, mean language scores had normalized, but there was little evidence of a treatment effect for receptive (adjusted mean difference 2.3; 95% confidence interval [CI] -1.2 to 5.7; P = .20) or expressive (0.8; 95% CI -1.6 to 3.2; P = .49) language. Of the secondary outcomes, only phonological awareness skills (effect size 0.36; 95% CI 0.08-0.65; P = .01) showed benefit. Costs were higher for intervention families (mean difference AU$4276; 95% CI: $3424 to $5128). CONCLUSIONS: Population-based intervention targeting 4-year-old language delay was feasible but did not have lasting impacts on language, possibly reflecting resolution in both groups. Long-term literacy benefits remain possible but must be weighed against its cost.

Preliminary study of the effect of low-intensity home-based physical therapy in chronic stroke patients

This study was a preliminary examination of the effect of low-intensity home-based physical therapy on the performance of activities of daily living (ADL) and motor function in patients more than 1 year after stroke. Twenty patients were recruited from a community stroke register in Nan-Tou County, Taiwan, to a randomized, crossover trial comparing intervention by a physical therapist immediately after entry into the trial (Group I) or after a delay of 10 weeks (Group II). The intervention consisted of home-based physical therapy once a week for 10 weeks. The Barthel Index (BI) and Stroke Rehabilitation Assessment of Movement (STREAM) were used as standard measures for ADL and motor function. At the first follow-up assessment at 11 weeks, Group I showed greater improvement in lower limb motor function than Group II. At the second follow-up assessment at 22 weeks, Group II showed improvement while Group I had declined. At 22 weeks, the motor function of upper limbs, mobility, and ADL performance in Group II had improved slightly more than in Group I, but the between-group differences were not significant. It appears that low-intensity home-based physical therapy can improve lower limb motor function in chronic stroke survivors. Further studies will be needed to confirm these findings.

Protocol for a home-based integrated physical therapy program to reduce falls and improve mobility in people with Parkinson’s disease

Background The high incidence of falls associated with Parkinson’s disease (PD) increases the risk of injuries and immobility and compromises quality of life. Although falls education and strengthening programs have shown some benefit in healthy older people, the ability of physical therapy interventions in home settings to reduce falls and improve mobility in people with Parkinson’s has not been convincingly demonstrated.
Methods/design 180 community living people with PD will be randomly allocated to receive either a home-based integrated rehabilitation program (progressive resistance strength training, movement strategy training and falls education) or a home-based life skills program (control intervention). Both programs comprise one hour of treatment and one hour of structured homework per week over six weeks of home therapy. Blinded assessments occurring before therapy commences, the week after completion of therapy and 12 months following intervention will establish both the immediate and long-term benefits of home-based rehabilitation. The number of falls, number of repeat falls, falls rate and time to first fall will be the primary measures used to quantify outcome. The economic costs associated with injurious falls, and the costs of running the integrated rehabilitation program from a health system perspective will be established. The effects of intervention on motor and global disability and on quality of life will also be examined.
Discussion This study will provide new evidence on the outcomes and cost effectiveness of home-based movement rehabilitation programs for people living with PD.

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.

Quality-of-life measurement in patients undergoing radiation therapy for head and neck cancer: a Hong Kong experience

The aims of this study are (1) to establish a reliable and valid quality-of-life (QOL) questionnaire for Chinese patients with head and neck (H&N) cancer who are treated with radiation therapy and (2) to evaluate the impact of the immediate side effects of treatment on the QOL of these patients. The 39-item "Quality of Life Radiation Therapy Instrument with Head and Neck Companion Module" (QOL-RTI/H&N) was translated into Chinese. In the reliability evaluation phase (study module 1), the questionnaire was administered twice to 56 H&N cancer patients, 7 days apart, during the second and third week of radiation therapy. In the validity evaluation phase (study module 2), 138 patients completed the QOL-RTI/H&N before starting and at the end of radiation therapy. Sixty-nine of these 138 patients also completed the QOL-RTI/H&N during the second week of their radiation therapy, at the same time as completing the Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N) questionnaire. Cronbach alpha coefficients were 0.88 for the general-tool QOL-RTI and 0.90 for the H&N subscale. Test-retest reliability was satisfactory with intraclass correlation coefficients of 0.89 for the general-tool QOL-RTI and 0.75 for the H&N subscale. The instrument can discriminate between patients with stage I or II disease and those with stage III or IV disease (P < .05). Concurrent validity was established by the good agreement with the FACT-H&N (r = 0.86, P < .001). A highly significant deterioration was in the QOL from the baseline to the end of treatment (mean difference for general tool = 1.95, P < .001; mean difference for H&N subscale = 4.85, P < .001). The Chinese QOL-RTI/H&N is a reliable and valid tool for determining the QOL in H&N cancer patients receiving radiation therapy. The immediate side effects of treatment had a significantly negative impact on the patients' QOL. The impact was relatively large for the functional and treatment-site aspects.

Service and support needs of Australian carers supporting a family member with disability at home

Background As part of an international, multicentre project, the service and support needs of Australian family carers were investigated.

Method A sample of 1,390, 448 family carers completed a self-report survey, including an adaptation of the Family Needs Survey (FNS) and several open-ended questions. A mixed method design was used, employing quantitative and qualitative analyses.

Results On the FNS the most frequently endorsed items were those relating to the need for information about services and, in particular, future, out-of-home accommodation. Similarly, the need for respite services was endorsed by over 80% of respondents. Comments indicated that access to and the quality of respite, day support, and therapy programs were a priority.

Conclusions Participants expressed the need for greater access to information. Access to appropriate respite options, together with quality day support and therapy services, remain a priority for family carers.

Patients and nurses' perspective on oxygen therapy : a qualitative study

Aim. This paper is a report of a study to describe patients' and nurses' perspectives on oxygen therapy.
Background. Failure to correct significant hypoxaemia may result in cardiac arrest, need for mechanical ventilation or death. Nurses frequently make clinical decisions about the selection and management of low-flow oxygen therapy devices. Better understanding of patients' and nurses' experiences of oxygen therapy could inform clinical decisions about oxygen administration using low-flow devices.
Methods. Face-to-face interviews with a convenience sample of 37 adult patients (17 cardio-thoracic: 20 medical surgical) and 25 intensive care unit nurses were conducted from February 2007 to September 2007. Interviews were audio-taped, transcribed verbatim and then analysed using a thematic analysis approach.
Findings. The patients identified three key factors that underpinned their compliance with oxygen therapy: (i) device comfort; (ii) ability to maintain activities of daily living; and (iii) therapeutic effect. The nurses identified factors, such as: (i) therapeutic effect, (ii) issues associated with compliance, (iii) strategies to optimize compliance, (iv) familiarity with device, (v) triggers for changing oxygen therapy devices, as being key to the effective management of oxygen therapy.
Conclusion. Differences between the patients' and nurses' perspective of oxygen therapy illustrate the variety of factors that impact on effective oxygen administration. Further research should seek to provide a further in-depth understanding of the current oxygen administration practices of nurses and the patient factors that enhance or hinder effectiveness of oxygen therapy. Detailed information about nurse and patient factors that influence oxygen therapy will inform a sound evidence base for nurses' oxygen administration decisions.

Are nurses the key to the increased uptake of frequent nocturnal home haemodialysis in Australia?

Background: Although there are significant benefits to frequent nocturnal home haemodialysis (NHHD) there has been a low acceptance of this therapy in Australia.

Aim: The aim of this paper is to explore and discuss the literature relating to the nursing barriers to frequent nocturnal home haemodialysis.

Methods: A search of nursing, medical, social work and psychological literature was performed.

Results: Nurses are key contributors to the increase of NHHD within the dialysis population. Knowledge, culture and nurse satisfaction are key areas to address to increase NHHD uptake.

Conclusion: Nurses need to challenge the cultural and organisational barriers that are preventing further uptake of NHHD. If nurses do not we cannot claim to be helping patients attain their best possible outcome.

Outpatient versus inpatient IV antibiotic management for pediatric oncology patients with low risk febrile neutropenia: a randomised trial

Febrile neutropenia (FN) is a frequent, serious complication of intensive pediatric chemotherapy regimens. The aim of this trial was to compare quality of life (QOL) between inpatient and outpatient intravenous antibiotic management of children and adolescents with low risk febrile neutropenia (LRFN).

Efficacy of mirtazapine add on therapy to haloperidol in the treatment of the negative symptoms of schizophrenia: a double-blind randomized placebo-controlled study.

The negative symptoms of schizophrenia remain a major clinical challenge. Mirtazapine is an antidepressant with antagonist properties at 5-HT2A, 5-HT3 and alpha 2 receptors as well as indirect 5-HT1a agonist effects. Many of these pharmacological actions have clinical or preclinical evidence of efficacy in schizophrenia. This study was a 6-week randomized placebo-controlled trial of mirtzepine or placebo add on to haloperidol 5 mg in the treatment of 30 patients with DSM-IV schizophrenia. The primary finding of the trial was a 42% reduction in Positive and Negative Syndrome Scale (PANSS) negative symptom scores in the mirtazapine group compared to placebo at the end of 6 weeks (mirtazapine 13.9, SD 1.56; placebo 23.9, SD 1.56; P = 0.000, F = 20.31, d.f. = 1). The PANNS total scores, Clinical Global Impression severity and improvement scales in addition showed superiority of mirtazapine over placebo. There was no difference between the groups on the Hamilton depression scale at endpoint, suggesting that the improvement in negative symptoms was not an artifact of mood improvement. These results suggest a potential role for mirtazapine in the negative symptoms of schizophrenia.

Reboxetine add on therapy to haloperidol in the treatment of schizophrenia: a preliminary double-blind randomized placebo-controlled study.

The negative symptoms of schizophrenia remain a major clinical challenge. Reboxetine is an antidepressant whose major mechanism of action is as a noradrenergic reuptake inhibitor. This study was a 6-week randomized placebo-controlled trial of reboxetine or placebo add on to haloperidol 5 mg in the treatment of 30 patients with DSM-IV schizophrenia. The trial failed to demonstrate any significant difference between the placebo and reboxetine groups on any of the outcome measures. This trial does not suggest that increased noradreneregic drive mediated by reuptake inhibition in patients taking dopamine antagonists is of therapeutic value in schizophrenia.
