Nursing home-acquired pneumonia (NHAP) is a diagnostic and therapeutic challenge, and antimicrobial therapy represents only 1 facet of the treatment of this disease. The nursing home population consists of a mixture of well, frail and dependent elderly. For some residents, supportive care may be the best therapeutic option. A variety of antimicrobial regimens have been proposed for the empirical therapy of NHAP; however, there are still very few data from controlled clinical trials that assess outcome. The clinical trials that have been completed support the concept that an early switch from intravenous to oral therapy can be successfully used to treat pneumonia affecting frail, often seriously ill, groups of patients. Annual influenza vaccine should be offered to all nursing home residents. This practice is about 50% effective in preventing hospitalisation and pneumonia, and about 80% effective in preventing death. The same level of evidence is not available to support the use of pneumococcal vaccine in this group; however, current practice suggests that all nursing home residents receive this vaccine on admission and once every 6 years thereafter. Frequently, knowledge about pneumonia is not applied as optimally as should be done. Care maps have been shown to reduce length of stay and shorten the time from emergency room entry until administration of antibiotic therapy by up to 3 hours. Areas for urgent research attention in patients with NHAP are: (a) proper studies to define the microbiological aetiology of NHAP (this requires bronchoscopy with sampling of the distal airways using a protected bronchial brush); (b) randomised controlled clinical trials of sufficient size to determine whether one antibiotic regimen is superior to another (currently most trials are designed to show that the agent under study is equivalent to a currently used agent); and (c) end-of-life decision making in the nursing home population.
养老院获得性肺炎(NHAP)是一个诊断和治疗方面的挑战,抗菌治疗只是这种疾病治疗的一个方面。养老院人群包括健康、体弱和依赖他人的老年人。对于一些居民来说,支持性护理可能是最佳治疗选择。针对NHAP的经验性治疗已经提出了多种抗菌方案;然而,来自评估结果的对照临床试验的数据仍然非常少。已完成的临床试验支持这样一个概念,即从静脉治疗成功转换为口服治疗可用于治疗影响体弱且往往病情严重的患者群体的肺炎。应向所有养老院居民提供年度流感疫苗。这种做法在预防住院和肺炎方面约有50%的效果,在预防死亡方面约有80%的效果。目前尚无同样水平的证据支持在该群体中使用肺炎球菌疫苗;然而,目前的做法是所有养老院居民在入院时接种该疫苗,此后每6年接种一次。通常,关于肺炎的知识并没有得到应有的最佳应用。护理流程图已被证明可缩短住院时间,并将从进入急诊室到开始抗生素治疗的时间缩短多达3小时。NHAP患者急需研究关注的领域包括:(a)进行适当研究以确定NHAP的微生物病因(这需要使用保护性支气管刷对远端气道进行采样的支气管镜检查);(b)开展足够规模的随机对照临床试验,以确定一种抗生素方案是否优于另一种方案(目前大多数试验旨在表明所研究的药物等同于目前使用的药物);以及(c)养老院人群的临终决策。
