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).

Dysphagia is a common and frequently undetected complication of many neurological disorders and of sarcopoenia in ageing persons. Spontaneous swallowing frequency (SSF) has been mooted as a possible tool to classify dysphagia risk. We conducted a review of the literature to describe SSF in both the healthy population and in disease-specific populations, in order to consider its utility as a screening tool to identify dysphagia. We searched Medline, Embase, Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials databases. Metadata were extracted, collated and analysed to give quantitative insight. Three hundred and twelve articles were retrieved, with 19 meeting inclusion and quality criteria. Heterogeneity between studies was high (I2 = 99%). Mean SSF in healthy younger sub-groups was 0.98/min [CI: 0.67; 1.42]. In the Parkinson’s sub-group, mean SSF was 0.59/min [0.40; 0.87]. Mean SSF in healthy older, higher risk and dysphagic populations were similar (0.21/min [0.09; 0.52], 0.26/min [0.10; 0.72] and 0.30/min [0.16; 0.54], respectively). SSF is a novel, non-invasive clinical variable which warrants further exploration as to its potential to identify persons at risk of dysphagia. Larger, well-conducted studies are needed to develop objective, standardised methods for detecting SSF, and develop normative values in healthy populations.

Respiratory tract infections are the commonest nosocomial infections, and occur predominantly in frailer, older patients with multiple comorbidities. The oropharyngeal microbiota is the major reservoir of infection. This study explored the relative contributions of time in hospital and patient demographics to the community structure of the oropharyngeal microbiota in older patients with lower limb fracture. We collected 167 throat swabs from 53 patients (mean age 83) over 14 days after hospitalization, and analyzed these using 16S rRNA gene sequencing. We calculated frailty/comorbidity indices, undertook dental examinations and collected data on respiratory tract infections. We analyzed microbial community composition using correspondence (CA) and canonical correspondence analysis. Ten patients were treated for respiratory tract infection. Microbial community structure was related to frailty, number of teeth and comorbidity on admission, with comorbidity exerting the largest effect. Time in hospital neither significantly changed alpha ( = -0.910, = 0.365) nor beta diversity (CA1 = 0.022, = 0.982; CA2 = -0.513, = 0.609) of microbial communities in patient samples. Incidence of respiratory pathogens were not associated with time in hospital ( = -0.207, = 0.837), nor with alpha diversity of the oral microbiota ( = -1.599, = 0.113). Patient characteristics at admission, rather than time in hospital, influenced the community structure of the oral microbiota.

Impaired swallowing can lead to malnutrition, dehydration, choking, reduced quality of life and death.5–7 Because so many people are at risk of developing AP, a significant emphasis of this Statement is on prevention. [...]microaspiration due to abnormal swallowing results from a wide range of pathologies, and so heterogeneous patient groups are included in published studies on AP. Every hospital and care home should have at least one oral health ‘champion’ promoting good oral healthcare. Oral examination should be performed in all hospitalised patients at risk of AP or with suspected AP, and at least weekly in care home residents, checking for infection (eg, candidiasis), quality of dentition, food residue and cleanliness of mucosal surfaces.

This review provides an update on current evidence surrounding the epidemiology, treatment and prevention of non-respiratory infections in care homes. It covers urinary tract infection (UTI), methicillin-resistant Staphylococcus aureus (MRSA), decubitus ulcers, scabies, tinea infections and viral and bacterial gastroenteritis. The care home sector provides a unique ecological niche for infections, housing frail older people with multiple co-morbidities and frequent contact with healthcare services in a semi-closed environment. This leads to differences in the diagnosis and management of infections – particularly of outbreaks – when compared with community-dwelling counterparts. It is essential that care home staff play a role in the early recognition, isolation and treatment of infections, but they are often not trained as healthcare professionals – this presents a challenge to systematized response. Effective interface between care homes, public health and infection control services are essential to the delivery of care, yet it is not clear how to structure such links most effectively.

This review provides an update on current evidence surrounding epidemiology, treatment and prevention of lower respiratory tract infection, with special reference to pneumonia and influenza, in care home residents. The care home sector is growing and provides a unique ecological niche for infections, housing frail older people with multiple co-morbidities and frequent contact with healthcare services. There are therefore considerations in the epidemiology and management of these conditions that are specific to care homes. Opportunities for prevention, in the form of vaccination strategies and improving oral hygiene, may reduce the burden of these diseases in the future. Work is needed to research these infections specifically in the care home setting, and this article highlights current gaps in our knowledge.

Oral mucosal lesions occur frequently in older people and are important as they may reduce quality of life, represent pre-malignant change or indicate systemic disease. The commonest mucosal lesions in adults are denture-related lesions such as stomatitis, angular cheilitis, ulcers and hyperplasia, and occur in 8.4% of the adult population. In the hospital setting, oral mucosal lesions may lead to malnutrition, slow rehabilitation and recovery from illness, and adversely affect quality of life. The two major risk factors associated with oral lesions are denture use and smoking, and frequently older people have been exposed to both of these. Commonly used drugs such as antihypertensives, antidepressants and antibiotics may have oral mucosal side-effects, and polypharmacy may worsen these. Decreased awareness of changes in the oral mucosa, or inability to raise concerns due to dementia, delirium, social isolation, or difficulty accessing dental care may further compound the problem. Hospital admission could represent an opportunity to intervene, but oral mucosal lesions, and indeed oral hygiene, are areas which can be overlooked by doctors. This article is intended to highlight common or important oral mucosal diseases and increase awareness of these conditions for the practising hospital or community geriatrician.

Hospital acquired pneumonia (HAP) occurs in 1% of all hospital in-patients, and in around 10% of patients with lower limb fracture, with a mortality of 18- 43%. HAP arises from interactions between three main risk factor groups: resident oral microbiota, aspiration potential (dysphagia, reduced conscious level) and host factors (age, frailty, comorbidity). In this work novel multiplex real time PCR assays were used to study prospectively the oral colonisation dynamics of seven major commensal pathogens over the first fortnight after hospital admission in relation to oral health variables, medical variables and subsequent development of HAP. Of the 93 patients recruited, 10% developed HAP and 60% of in-hospital deaths after lower limb fracture were due to HAP. Persistent oral colonisation with E. coli or S. aureus was significantly associated with HAP or HAP/lower respiratory tract infection in older patients with lower limb fracture. In turn, S. aureus was associated with increased dental plaque at admission and with increased xerostomia indices at 14 days. Other factors such as witnessed aspiration and post-operative cough were also strongly associated with subsequent development of HAP. HAP was associated with increased risk of death and increased length of hospital admission. These findings suggest several potentially modifiable clinical risk factors, and a high risk population for HAP, to whom interventions could be targeted. Given the rise in the older population and the increased costs associated with HAP, early detection and prevention will become increasingly important. Further work is needed to understand the relationships between dental plaque, S. aureus and xerostomia, and also to identify microbial biomarkers which could be used at the start of hospital admission to stratify patients’ risk of HAP.

Hospital acquired pneumonia (HAP) is often fatal in older patients. The mouth is the main reservoir of infection and studies have suggested that oral hygiene interventions may prevent HAP. The aim of this study was to investigate associations between HAP and preceding a) heavy dental plaque and b) oral carriage of potential respiratory pathogens in older patients with lower limb fracture to determine the target for intervention studies. Methods 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. Results 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).

Conclusions 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).

He would never admit it, but a midweek trip to Ross County was probably the last thing Neil Lennon fancied after Celtic's Old Firm capitulation to Rangers at the weekend. It was County who inflicted a bloody nose on Celtic in the Scottish Cup semi-final of 2010. Celtic's manager need not have fretted. \"It was exactly the reaction I wanted,\" Lennon said, in reference to Sunday's 4-2 loss at Ibrox. \"It was an excellent workout. We won't get carried away but it was a small step in the right direction.\" Lennon said his team's \"performance and professionalism\" had pleased him most.
