The advent of PCR has improved the identification of viruses in patients with communityacquired pneumonia (CAP). Several studies have used PCR to establish the importance of viruses in the aetiology of CAP.We performed a systematic review and meta-analysis of the studies that reported the proportion of viral infection detected via PCR in patients with CAP. We excluded studies with paediatric populations. The primary outcome was the proportion of patients with viral infection. The secondary outcome was short-term mortality.Our review included 31 studies. Most obtained PCR via nasopharyngeal or oropharyngeal swab. The pooled proportion of patients with viral infection was 24.5% (95% CI 21.5-27.5%). In studies that obtained lower respiratory samples in >50% of patients, the proportion was 44.2% (95% CI 35.1-53.3%). The odds of death were higher in patients with dual bacterial and viral infection (OR 2.1, 95% CI 1.32-3.31).Viral infection is present in a high proportion of patients with CAP. The true proportion of viral infection is probably underestimated because of negative test results from nasopharyngeal or oropharyngeal swab PCR. There is increased mortality in patients with dual bacterial and viral infection. @ERSpublications Viral infection is present in a high proportion of patients with community-acquired pneumonia
During the Gulf War in 1991 a telephone-based support system was established for elderly patients living at home in Israel. The study population involved 93 elderly patients (mean age 74), who had recently been discharged from hospital and were chosen for supervision by the Home-Care Unit of the Tel Aviv Sourasky Medical Center, Israel. Two different teams were involved with the telephone support calls: secretarial staff (nonprofessional team) and social workers (professional team). The research examined the characteristics of the study population and also included a comparison between the two groups of patients receiving the psycho-social support. The latter indicated that better results of outcome indices were achieved by the professional team. Further, this study demonstrated the feasibility of telephone-support outreach as an interventional strategy for psycho-social support for elderly patients at a time of crisis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
