Dental and microbiological risk factors for hospital-acquired pneumonia in non-ventilated older patients

We obtained a time series of tongue/throat swabs from 90 patients with lower limb fracture, aged 65-101 in a general hospital in the North East of England between April 2009-July 2010. We used novel real-time multiplex PCR assays to detect S. aureus, MRSA, E. coli, P. aeruginosa, S. pneumoniae, H. influenza and Acinetobacter spp. We collected data on dental/denture plaque (modified Quigley-Hein index) and outcomes of clinician-diagnosed HAP.The crude incidence of HAP was 10% (n = 90), with mortality of 80% at 90 days post discharge. 50% of cases occurred within the first 25 days. HAP was not associated with being dentate, tooth number, or heavy dental/denture plaque. HAP was associated with prior oral carriage with E. coli/S. aureus/P.aeruginosa/MRSA (p = 0.002, OR 9.48 95% CI 2.28-38.78). The incidence of HAP in those with carriage was 35% (4% without), with relative risk 6.44 (95% CI 2.04-20.34, p = 0.002). HAP was associated with increased length of stay (Fishers exact test, p=0.01), with mean 30 excess days (range -11.5-115). Target organisms were first detected within 72 hours of admission in 90% participants, but HAP was significantly associated with S. aureus/MRSA/P. aeruginosa/E. coli being detected at days 5 (OR 4.39, 95%CI1.73-11.16) or 14 (OR 6.69, 95%CI 2.40-18.60).Patients with lower limb fracture who were colonised orally with E. coli/ S. aureus/MRSA/P. aeruginosa after 5 days in hospital were at significantly greater risk of HAP (p = 0.002)

Trends in nursing research in France: a cross-sectional analysis

International audienceAimTo examine the engagement of French registered nurses with the Ministry of Health's initiative to spur scientific inquiry in the community.BackgroundFrench nursing research has suffered from a lack of dedicated funding. Positive signs of change have recently appeared, with the launch of the first national public funding programme dedicated to nursing research. This initiative, begun in 2010, was launched by the French Ministry of Health. Through this initiative, 149 registered nurses, serving as principal investigators, and their teams submitted research proposals between 2010 and 2011. The administrative guidelines of the funding programme are clearly oriented towards producing quantitative and exogenous nursing research.MethodA cross-sectional analysis of 149 nursing research projects submitted during the first and second years of a French national funding programme for hospital-based nursing research was conducted. Research proposals were included in the analysis whether they received funding or not. Data collection took place in 2011. The categories used in the analysis were the following: (1) the socio-demographic data on the registered nurse principal investigators, (2) the research teams and (3) the research proposals (methodologies, bibliography, focus of the research, output, the status of the research proposals).ResultsThis study highlights the presence of methodological homogeneity among the research proposals submitted for funding. Clear tendencies were towards interventional and quantitative studies and those with an exogenous factor research objective. Between 2010 and 2011, 25 projects were funded out of 149 submitted. They were mostly quantitative and/or focused on the exogenous factors in patient care.ConclusionThe socio-political context of a funding programme designed to encourage nursing research has had an implicit influence on the type of research to which French nurses have committed themselves to and the scientific positions with which these nurse researchers align themselves
