Aim of the review To study the prevalence of drug interactions in hospital healthcare by reviewing literature. Method A review was carried out of studies written in Spanish and English on the prevalence of drug interactions in hospital care published in Pubmed between January 1990 and September 2008. The search strategy combined free text and MeSH terms, using the following keywords: ??Drug interaction??, ??prevalence?? and ??hospital??. For each article, we classified independent variables (pathology, age of population, whether patients were hospitalized or not, geographical location, etc.) and dependent variables (number of interactions per 100 patients studied, prevalence of patients with interactions, most common drug interactions, and others). Results The search generated 436 articles. Finally, 47 articles were selected for the study, 3 provided results about drug interactions with real clinical consequences, 42 about potential interactions, and 2 described both. The prevalence of patients with interactions was between 15 and 45?% and the number of interactions per 100 patients was between 37 and 106, depending on the group of studies analyzed. There was a considerable increase in these rates in patients with heart diseases and elderly persons. Conclusion There is a large number of studies on the prevalence of drug interactions in hospitals but they report widely varying results. The prevalence is higher in patients with heart diseases and elderly people. 相似文献

Currently in Brazil, living donor liver transplantation (LDLT) represents 8.5% of liver transplantation (LT), being the majority pediatric one. Up to now, according to Brazilian Organ Transplantation Association (ABTO) annual report, 2,086 procedures have been done nationwide, most of them in southeast and south regions. Based on national centers reports, biliary complication is the most common recipient postoperative complication (14.5–20.6%), followed by hepatic artery thrombosis (3.1–10.7%) and portal vein thrombosis (2.3–9.1%). Patient and graft overall 5-y survival correspond to 76% and 74%, respectively. Regarding the donor, morbidity rate ranges from 12.4% to 28.3%, with a national mortality rate of 0.14%. In conclusion, Brazilian LDLT programs enhance international experience that this is a feasible and safe procedure, as well as an excellent alternative strategy to overcome organs shortage. 相似文献

IntroductionSilicosis is a chronic progressive disease caused by inhalation of crystalline silica. Most cases develop in underground mine workers and in subjects involved in the extraction of natural stone (slate and granite). In view of the progressive emergence of new cases of silicosis in artificial quartz conglomerate workers, we performed a study to analyze the characteristics of silicosis produced by this new agent in Spain.MethodsThe study consisted of a series of 96 cases of silicosis diagnosed according to international criteria during the period 2010-2017. We analyzed clinical, radiological, pathological and functional characteristics.ResultsMean age of participants was 45 years; 55% had simple silicosis and 45% had complicated silicosis. Ten patients were diagnosed with accelerated silicosis, with a mean age of 33 years. Mean time of exposure to conglomerates was 15 years, and 77% had not used appropriate protection measures. Half of the patients were asymptomatic and presented different classic forms on chest X-ray and chest high-resolution computed tomography, along with ground-glass images. No lung function changes were recorded.ConclusionsSilicosis in artificial quartz conglomerate workers occurs in a young, actively employed population, a considerable percentage of whom present an accelerated form. They have few symptoms and no functional limitations. Protection measures are scarce. It is important to characterize these features to provide early diagnosis and implement the necessary preventive measures. 相似文献

Although concern for patient safety is inherent to the practice of the health care professions, its transformation into a specific body of knowledge is relatively recent and thus patient safety may be considered as a comparatively ‘new’ discipline. Its main objectives are to avoid the occurrence of preventable adverse events (accidents, errors and complications) associated with health care and to limit the impact of inevitable adverse events. Despite these simple definitions, patient safety is multifaceted, quite complex in nature and includes many key elements. Thus, it cannot be simply defined as the provision of safe health care or the protection of patients from harm by health care providers because there are economic, fiscal, social, cultural and organisational aspects of a patient safety climate. It is essential for all health care practitioners and health care organisations to become more familiar with the general context of patient safety, to actively participate in efforts to implement patient safety measures in daily practice and to establish a patient safety culture. 相似文献
