Background: Children with intellectual disabilities often have difficulties in daily tasks, requiring training to increase functional independence. This study measured the effectiveness of community skills training in a telephone task and a shopping task, and examined if community-based training was more effective than classroom-based training. Material and methods: A randomized control trial with 40 children aged 9–11years was completed. Intervention groups attended an eight-week training programme; the control group received no treatment. One intervention group practised skills in local shops. All participants were assessed before and after treatment in a shopping task and telephone task, using task analysis methodology. Results: Data showed a highly statistically significant difference between intervention and control groups in the shopping task (p=0.007); however, there was no significant difference between classroom and classroom supplemented by community-based learning in the shopping task. There was no significant difference between the intervention and control groups in the telephone task. Conclusion: Results suggested that skills training was effective in one of the skill areas with this client group. Further research is required to determine if community-based training is more effective than classroom-based learning.  相似文献

The aim of this study was to investigate perceptions on the use of smokeless tobacco in the Northern Province, South Africa. Ten focus groups were conducted in 1999 with two heterogeneous groups (5 with middle-aged and 5 with the aged). They were mainly Northern Sotho speaking. From 72 participants 16 women and 8 men admitted to using snuff. The most popular types of smokeless tobacco used were homemade snuff and only a few used ‘commercial” snuff. The basic ingredients for homemade snuff were tobacco and other plant leaves. Snuff was found to have important functions and to be socially acceptable in the groups studied mainly for ceremonial and medicinal use and to a lesser degree for relaxation and pleasure. Generally, positive and medicinal effects were noted for snuff use. Most participants agreed that it is addictive, but only a few acknowledged the negative effects in terms of causing cancer.  相似文献

General practitioners (GPs) are frontline health workers. They should be sensitive to the health needs of the community in addition to caring for patients that visit their practice. Due to changes in demography, epidemiology, ecology and healthcare policy, a community orientation becomes more important. Our research question is: to what extent does community orientation of GPs vary between countries and GPs and how can this variation be explained? We use cross-sectional survey data from the QUALICOPC study, conducted among over 7000 GPs in 34 countries. Community orientation was measured through a scale constructed from three survey questions on whether GPs would take action when confronted with: repeated accidents in an industrial setting, frequent respiratory problems in patients living near a certain industry, and repeated cases of food poisoning in the local community. Independent variables are at healthcare system level and GP or practice level. Data were analysed using linear multilevel regression analysis. Community orientation varies between GPs and countries. Community orientation is more frequent in healthcare systems with a list system, among self-employed GPs, those using medical records to make overviews, and those more active in prevention and multidisciplinary cooperation. GPs in rural areas and areas with more people from ethnic minorities are more community oriented. Based on the variation between countries and GPs, we would like to raise awareness and underline the importance of multidisciplinary cooperation.  相似文献

Countries around the globe have responded to pandemic preparedness and developed strategies to cope with the COVID-19 crisis. In this context, the role of healthcare professionals is of paramount importance. Pharmacists are playing a vital role in dealing, preparedness, prevention, protection, promoting access to medicines and to improve health outcomes during this crisis. In this context, “Drive-thru” pharmacy services improve access to medicines while ensuring the preventive measures suggested by the World Health Organization. This commentary provides an overview of opportunities and challenges related to the implementation of “drive-thru pharmacy services” and their role in improving public health during this crisis.  相似文献

《Injury》2016,47(1):244-249
IntroductionFalls incur nearly 35 million disability-adjusted life-years annually; 75% of which occur in low- and middle-income countries. The epidemiology of civilian injuries during conflict is relatively unknown, yet important for planning prevention initiatives, health policy and humanitarian assistance. This study aimed to determine the death and disability and household consequences of fall injuries in post-invasion Baghdad.MethodsA two-stage, cluster randomised, community-based household survey was performed in May of 2014 to determine the civilian burden of injury from 2003 to 2014 in Baghdad. In addition to questions about household member death, households were interviewed regarding injury specifics, healthcare required, disability, relatedness to conflict and resultant financial hardship.ResultsNine hundred households totaling 5148 individuals were interviewed. There were 138 fall injuries (25% of all injuries reported); fall was the most common mechanism of civilian injury in Baghdad. The rate of serious fall injuries increased from 78 to 466 per 100,000 persons in 2003 and 2013, respectively. Fall was the most common mechanism among the injured elderly (i.e. ≥65 years; 15/24 elderly unintentional injuries; 63%). However, 46 fall injuries were children aged <15 years (49% of unintentional injuries) and 77 were respondents aged 15–64 years (36%). Respondents who spent significant time within the home (i.e. unemployed, retired, homemaker) had three times greater odds of having suffered a fall injury than student referents (aOR 3.34; 95%CI 1.30–8.60). Almost 80% of fall injured were left with life-limiting disability. Affected households often borrowed substantial sums of money (34 households; 30% of affected households) and/or suffered food insecurity after a family member's fall (52; 46%).ConclusionFalls were the most common cause of civilian injury in Baghdad. In part due to the effect of prolonged insecurity on a fragile health system, many injuries resulted in life-limiting disabilities. In turn, households shouldered much of the burden after fall injury due to loss of income and/or medical expenditure, often resulting in food insecurity. Given ongoing conflict, civilian injury control initiatives, trauma care strengthening efforts and support for households of the injured is urgently needed.  相似文献
