Objectives: There is a growing need for evaluation of the results of mental health services and clinical treatment in older people, but evidence for effectiveness is limited in Greece. The Health of the Nations Outcome Scales for Elderly People (HoNOS65+) are promising instruments for the assessment of mental, physical and social health in older persons. They have been translated into the Greek language but have not been validated. The aim was to assess the inter-rater reliability, intraclass correlation, concurrent validity, internal consistency and sensitivity to change of HoNOS65+ in a Greek sample of older people with mental health problems. Method: Two samples, one of inpatients in a psychiatric hospital and the other of older people living in the community were used. In order to test the extent to which the HoNOS65+ were sensitive to change the first sample was reassessed after two months and the second after three months. For each participant HoNOS65+ were completed by two independent raters, and the clinician rated blindly each participant on the Stockton Geriatric Rating Scale and a scale which measured behavioural, physical, cognitive and emotional status. Results: In both groups (inpatients n?=?50, community n?=?65), the inter-rater reliability, intraclass correlation and concurrent validity were high while internal consistency of the scales taken together was low. At reassessment in 98 participants, HoNOS65+ showed changes comparable to clinician ratings. Conclusion: The Greek version of HoNOS65+ can achieve high levels of reliability, validity and sensitivity to change for measuring outcomes in older people with mental health problems. 相似文献

We report on two pregnant women who either had de novo restless legs syndrome (RLS) or had marked enhancement of preexisting RLS symptoms during pregnancy. Both patients had ferritin values <50 μg/L at baseline. The patients had relevant sleep disorders and daytime symptoms caused by RLS. The women were treated in an open paradigm with intravenous iron sucrose. A few weeks after therapy, both patients experienced a significant reduction or even remission of RLS symptoms. Their quality of life and sleep substantially improved and no treatment-related adverse effects were observed. According to our initial experience, intravenous iron sucrose administration appears to be an effective therapy in RLS patients with low ferritin values during pregnancy. 相似文献

ObjectivesWe aimed to examine the relationships between asthma control, daytime sleepiness, and asthma-specific health-related quality of life (HRQOL) among children with asthma. Path analyses were conducted to test if daytime sleepiness can mediate the effect of asthma control status on asthma-specific HRQOL.Methods160 dyads (pairs) of asthmatic children and their parents were collected for analyses. The Asthma Control and Communication Instrument (ACCI) was used to categorize adequate and poor asthma control status. The Cleveland Adolescent Sleepiness Questionnaire (CASQ) was used to measure children’s daytime sleepiness, including sleep in school, awake in school, sleep in evening, and sleep during transport. The Patient-Reported Outcomes Measurement Information System (PROMIS) Asthma Impact Scale was used to measure asthma-specific HRQOL.ResultsPoorly controlled asthma was associated with daytime sleepiness and impaired asthma-specific HRQOL. Asthma control status was directly associated with asthma-specific HRQOL (P < .05), whereas sleep in school and sleep in evening domains of daytime sleepiness significantly mediated the relationship between poor asthma control and impaired HRQOL (P < .01).ConclusionsAsthma control status was associated with pediatric asthma-specific HRQOL, and the association was significantly mediated by daytime sleepiness. Healthcare providers need to address pediatric sleep needs related to poor asthma control to reduce the negative impact on HRQOL. 相似文献

AbstractObjective: Patient-centered outcomes research is predicated on the idea that the opinions, attitudes, and preferences of patients should help inform study design and interpretation. To date, little is known about what defines patient-centered outcomes from cognitive evaluations. The current evaluation sought to explore this issue in persons with Parkinson’s disease (PwPD) and their care partners (CP). Method: Focus groups of 22 PwPD/CP dyads were conducted to identify potential consumer oriented endpoints from cognitive evaluations. These endpoints were utilized to create a Patient-Centered Cognitive Assessment Outcomes Scale, which was administered to a different group of 50 PwPD/CP dyads who rated the importance of each outcome and identified their top three priority outcomes. Results: Three themes emerged from the focus groups: improved knowledge, advice, and planning. Both PwPD and CP rated items in all three domains as being very important outcomes. Priorities for outcomes in both groups favored treatment planning information slightly above knowledge based outcomes. Conclusions: The PwPD and CP identified improved knowledge, advice for daily activities, and knowledge they could use to plan for future eventualities as very important. This information can be used as a framework for future studies aimed at demonstrating patient-centered outcomes from neuropsychological evaluations. Implications for future research are discussed. 相似文献

Executive skills and their functional implications: Approaches to rehabilitation after childhood TBI
《Developmental neurorehabilitation》2013,16(5):352-360
Background: It is widely acknowledged that children recover differently from adults following traumatic brain injury. The impact of neurological injury in the context of developing skills and changing expectations of behaviour requires a developmental approach to rehabilitation that considers children's abilities across home, school and community environments.Methods: This article aims to provide an overview of the impact of executive deficits on everyday functioning and to review information about intervention strategies that support long term development of skills.Results and conclusions: While individual disciplines are not directly referred to in this paper, input from a comprehensive and co-ordinated interdisciplinary team is crucial to understanding and reducing the impact of executive deficits on functional performance. 相似文献
