Abstract
Background and purpose - Understanding the key drivers of hospital variation in postoperative infections after hip fracture surgery is important for directing quality improvements. Therefore, we investigated variation in the risk of any infection, and subgroups of infections including pneumonia and sepsis after hip fracture surgery.Methods - In this nationwide population-based cohort study, all Danish patients aged ≥ 65 undergoing surgery for an incident hip fracture from 2012 to 2017 were included. Risk of postoperative infections, based on data from hospital registration (hospital-treated infections) and antibiotic dispensing (community-treated infections), were calculated using multilevel Poisson regression analysis. Hospital variation was evaluated by intra-class coefficient (ICC) and median risk ratio (MRR).Results - The risk of hospital-treated infection was 15%. The risk of community-treated infection was 24%. The adjusted risk varied between hospitals from 7.8-25% for hospital-treated infection and 16-34% for community-treated infection. The ICC indicated that 19% of the adjusted variance was due to hospital level for hospital-treated infection. The ICC for community-treated infections was 13%. The MRR showed a 2-fold increased risk for the average patient acquiring a hospital-treated infection at the highest risk hospital compared with the lowest risk hospital. For community-treated infection, the MRR was 1.4.Interpretation - Our results suggest that 20% of infections could be reduced by applying the top performing hospitals' approach. Nearly a 5th of the variation was at the hospital level. This suggests a more standardized approach to avoid postoperative infection after hip fracture surgery.Hip fracture is a leading cause of hospital admission among the elderly. The 30-day mortality following hip fracture surgery has been approximately 10% during the last few years in Denmark (Pedersen et al. 2017). Higher mortality after hip fracture has been associated with a range of hospital factors (Kristensen et al. 2016, Sheehan et al. 2016) and patient factors in observational studies (Roche et al. 2005). Furthermore, variation in 30-day mortality after hip fracture surgery has been observed between Danish hospitals, but not fully explained (Kristensen et al. 2019).

Abstract
Introduction: Pneumonia is an important cause of death in patients with schizophrenia. It is critical to understand the risk factors of hospital-acquired pneumonia (HAP) and determine prevention strategies to reduce HAP. The aim of this study is to elucidate the risk factors for HAP in the middle-aged and elderly hospitalized patients with schizophrenia. Methods: We retrospectively reviewed the medical records of 2,617 the middle-aged and elderly patients (age ≥ 50) with schizophrenia who were admitted for the first time to a large-scale psychiatric hospital between 2016 and 2020. The factors related to the incidence of HAP in patients were analyzed, including personal characteristics, antipsychotics, and non-antipsychotics. Results: The HAP infection rate of hospitalized the middle-aged and elderly patients with schizophrenia was 7.8%. Chi-square analyses showed that older age, male, and ≥60 days of hospitalization were risk factors for HAP infection (χ2 = 94.272, p < 0.001; χ2 = 22.110, p < 0.001; χ2 = 8.402, p = 0.004). Multivariate logistic regression showed that quetiapine, clozapine, and olanzapine significantly increased the incidence of HAP (OR = 1.56, 95% CI = 1.05-2.32, p = 0.029; OR = 1.81, 95% CI = 1.26-2.60, p = 0.001; OR = 1.68, 95% CI = 1.16-2.42, p = 0.006). Antipsychotic drugs combined with aceglutamide had an effect on HAP (OR = 2.19, 95% CI = 1.38-3.47, p = 0.001). Conclusion: The high HAP infection rate in hospitalized the middle-aged and elderly patients with schizophrenia may be related to the increase of age and the use of antipsychotic drugs. The types and dosages of antipsychotic drugs should be minimized while paying attention to the mental symptoms of patients.

Abstract
The COVID19 outbreak in Italy is still a big concern. The Italian Government has recommended citizens to respect faithfully any compulsory legal disposition in order to stay home and so contributing in escaping viral contacts and slowing down epidemic. Emergency has raised a widely animated debate about how to read and comprehend the daily case numbers, the medical and caregivers availability, the needs to swab asymptomatic subjects. In this review the authors discuss about the many wheat and chaffs of how this virus disease is addressed .

Abstract
An observational prospective cohort study was conducted on 1,353 observations from a convenience sample of 311 long-term-care (LTC) residents to evaluate the effectiveness of a nurse practitioner-led outreach program on the health outcomes, emergency department (ED) transfers, and hospital admissions of LTC residents. The results show that ED transfers by the NPs were 27% less likely to be non-urgent than transfers made by MDs (OR = .73; 95% CI .54-.97) and that ED transfers by the NPs were 3.23 times more likely to be admitted to hospital than transfers by MDs (OR = 3.23; 95% CI 1.17-8.90). These findings highlight the potential benefits of the NP-led outreach program for LTC residents and for the health-care system.

Abstract
OBJECTIVEBilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors are associated with the retreatment of bCSDH with a focus on surgical laterality.METHODSIn a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012. Univariate and multivariate analyses were performed to determine the relationship between retreatment of bCSDH and clinical, radiological, and surgical variables.RESULTSTwo hundred ninety-one patients with bCSDH were identified, and 264 of them underwent unilateral (136 patients) or bilateral (128 patients) surgery. The overall retreatment rate was 21.6% (57 of 264 patients). Cases treated with unilateral surgery had twice the risk of retreatment compared with cases undergoing bilateral surgery (28.7% vs 14.1%, respectively, p = 0.002). In accordance with previous studies, the data also showed that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment.CONCLUSIONSIn bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical procedure.

Abstract
BACKGROUND Signs and symptoms of infection in frail elderly are atypical, causing delay in diagnosis and treatment. To improve communication between healthcare staff of signs and symptoms of infection we developed an instrument, using qualitative data from observations by nursing assistants when they suspected infection. The aim of this study was to assess the validity of nursing assistants observations by developing and testing the instrument for early detection of infection in elderly nursing home residents. METHODS The early detection of infection (EDIS) instrument was based on data from focus interviews with nursing assistants. Over one year the nursing assistants used EDIS to document episodes of suspected early signs and symptoms of infection in 204 nursing home residents. Two physicians classified documented episodes as "no infection", "possible infection", and "infection". The content validity of the 13 items of the EDIS was established to explore the relationships between the items. The construct validity was used to explore the relationship between the items and the presence or absence of infection. The predictive value of the developed model was evaluated by the percentage of correct classifications of the observed cases. Generalized linear model (ordinal multinomial distribution and logit link) was used. RESULTS Of the 388 events of suspected infection, 20 % were assessed as no infection, 31 % as possible infection and 49 % as infection. Content validity analysis showed that 12/13 of the items correlated significantly with at least one other statement. The range in number of significant inter-correlations was from 0 ("pain") to 8 ("general signs and symptoms of illness"). The construct validity showed that the items "temperature" , "respiratory symptoms" and "general signs and symptoms of illness" were significantly related to "infection", and these were also selected in the model-building. These items predicted correct alternative responses in 61 % of the cases. CONCLUSION The validation of EDIS suggests that the observation of "general signs and symptoms of illness", made by nursing assistants should be taken seriously in detecting early infection in frail elderly. Also, the statement "He/She is not as usual" should lead to follow-up.

Abstract
PURPOSE The aim of this study was to assess the incidence of methicillin-resistant Staphylococcus aureus (MRSA) colonisation in patients admitted into a level 1 German trauma centre with proximal femur fractures, to correlate this incidence with defined risk factors for MRSA colonisation and to determine its influence on morbidity and mortality. METHODS Between August and November 2006, 65 patients were included in the study. Cotton-tipped swab samples were taken from the nose, throat, groin and any skin defects in the emergency room. The following factors were recorded: age, gender, any concomitant diseases, the fracture type and treatment device, skin lesions, hospitalisation within the last year, any urinary or vascular catheters, a nasogastric or gastrostomy tube, an ileal stoma, the use of a respirator and antibiotic therapy within the last year. During follow-up, data concerning any surgical site infections; any chest, urinary or vascular catheter infections; the success of decontamination and death within 1 year after surgery were collected. RESULTS The risk factors for MRSA colonisation were positive in 40 patients. The incidence of MRSA colonisation was 17%, which is higher than in most comparable studies but consistent with some very recent publications. The nosocomial infection rates, surgical site infection rates and mortality within the 1-year follow-up period were significantly higher in the MRSA-colonised patients. CONCLUSION The high incidence of MRSA in this study supports the need for systematic detection of MRSA-colonised patients. In our hospital, any patient with positive risk factors for MRSA colonisation is swabbed in the emergency room and treated as MRSA positive until proven otherwise.

Abstract
The frequency of hospitalization among the elderly in the United States caused by gastrointestinal diseases between 1991 and 2004 increased dramatically, especially hospitalization of elderly individuals with nonspecific diagnoses. We analyzed 6 640 304 gastrointestinal disease-associated hospitalization records in this 14-year period by comparing the peak times of nonspecific gastrointestinal diseases with those of specific diseases. We found that most nonspecific gastrointestinal diseases peak concurrently with viral enteritis, suggesting a lack of diagnostic testing for viruses, which may adversely affect the efficiency of prevention, surveillance, and treatment efforts.

Abstract
Health care-associated infections (HAIs) have become more common as medical care has grown more complex and patients have become more complicated. HAIs are associated with significant morbidity, mortality, and cost. Growing rates of HAIs alongside evidence suggesting that active surveillance and infection control practices can prevent HAIs led to the development of hospital epidemiology and infection control programs. The role for infection control programs has grown and continues to grow as rates of antimicrobial resistance rise and HAIs lead to increasing risks to patients and expanding health care costs. In this review, we summarize the history of the development of hospital epidemiology and infection control, common HAIs and the pathogens causing them, and the structure and role of a hospital epidemiology and infection control program.

Abstract
AIM To explore early nonspecific signs and symptoms of infection in elderly institutionalized individuals as described by nursing assistants. BACKGROUND Nonspecific signs and symptoms and lack of specific ones are common in connection with infection in institutionalized elderly persons and contribute to a delayed diagnosis and treatment. In clinical care, the nurse makes notes on the individual status of the patient on a daily basis and decides whether to contact the physician or not. However, in Sweden nursing assistants provide most of the daily care and therefore have many opportunities to observe subtle changes that may be early signs of infection. METHOD Data were collected in 2006 from focus interviews with 21 female nursing assistants. The interviews were verbatim transcripted and analysed with qualitative content analysis for manifest content with no preconceived categories. FINDINGS Nursing assistants' descriptions of nonspecific signs and symptoms of infection comprised two exclusive categories. Is not as usual described general signs and symptoms of discomfort related to possible infection, such as discomfort, unrestrained behaviour, aggressiveness, restlessness, confusion, tiredness and feebleness, and decreased eating. Seems to be ill was more distinctly related to signs and symptoms of established infection in general terms of fever and pain or more specifically related to pneumonia, urinary tract infection, skin infection, cold and eye infection. CONCLUSION Nursing assistants have a keen observational ability to detect early signs that might help to confirm suspected infections in elderly nursing home residents early on. Whether or not the cited categories are actual early signs and symptoms of infectious disease needs to be further investigated.

Abstract
The rate of healthcare-associated infections can be regarded as an important outcome parameter of the hygienic quality of care in nursing homes. Our study aimed to evaluate the applicability of repeated prevalence investigations as a tool for surveillance of healthcare-associated infections in nursing homes. From December 2006 to September 2007 a total of five prevalence investigations were conducted in four nursing homes each (n=2,369 residents). Initially, defined structural and procedural parameters of the hygienic quality of the four nursing homes were evaluated based on a detailed inspection and a checklist including 40 parameters. The results showed a uniformly high level of the hygienic quality with only minor variation (mean 84%, range 75%-93% of parameters fulfilled). In total, the prevalence of healthcare-associated infections was 6.8%, with a marked increase with higher categories of dependency (3.5%, 4.0%, 8.5%, and 12.3%, respectively, in the categories 0, I, II, and III of the German grading of skilled nursing care). Respiratory tract (4.1%), skin/soft tissue (1.5%), and urinary tract infections were the most prevalent healthcare-associated infections. Respiratory tract infections showed a marked seasonal pattern. During the second prevalence investigation (February 2007), an outbreak of upper respiratory tract infections occurred in one of the nursing homes (attack rate, 17%). The crude prevalence rates showed considerable differences between the four nursing homes; however, after adjusting for the different categories of dependency, the standardized infection rates (SIR) were largely comparable (excluding the outbreak). After inclusion of the outbreak, the SIR of the specific nursing home was significantly higher compared to all other nursing homes. In conclusion, our study shows that repeated prevalence investigations can be an easy to use tool for surveillance of healthcare-associated infections as a surrogate parameter of the hygienic quality in nursing homes. This implies a knowledge of the seasonality of specific infections and a risk adjustment according to the categories of dependency. The primary intention of surveillance should be the identification of hygienic problems. However, the resources should preferentially be focused on hygienic structures and processes.

Abstract
OBJECTIVES Radiofrequency ablation (RFA) has been used to treat hepatic, renal and prostate tumors. Preliminary experiences in breast cancer, followed by surgical excision, were encouraging. We performed a pilot trial of ultrasound-guided percutaneous RFA, not followed by surgery, in three elderly inoperable patients with breast carcinoma. The study was undertaken to determine the feasibility of treating small breast malignancies with RFA only and to evaluate the safety and complications related to this treatment. METHODS Three patients with core-needle biopsy-proven invasive carcinoma (<2 cm in greatest dimension) underwent ultrasound-guided RFA under local anesthesia, as outpatient procedure. Treatment was planned to ablate the tumor and a margin of surrounding breast tissue. All the patients were evaluated after a 1, 6, 12 and 18 months of follow-up. RESULTS All the patients completed the treatment with minimal or no discomfort and returned home after 1 h. The mean age was 81.3 years (range, 76-86 years) and the mean tumor size was 11.6 mm (range, 10-13 mm). The tumors laid more than 10 mm from chest wall and from the skin. The mean time required for ablation was 10.3 min (range, 8-12 min). There were no treatment-related complications. Post-ablation ultrasound scan, mammography, Magnetic Resonance Imaging scan and core biopsy, confirmed the tumor necrosis. After 18 months of follow-up no recurrence occurred. CONCLUSIONS RFA was feasible and safe for minimally invasive treatment of elderly inoperable patients with early-stage, primary breast carcinoma.

Abstract
The objective of this study was to determine the frequency and the pattern of hospital-acquired infections (HAIs) in elderly (age over 65) patients, using routine surveillance data collected by the infection control committee in Dokuz Eylül University Hospital. In this study, 199 elderly patients diagnosed with HAIs in the years of 1999-2000 were included. During this period, 22.7% of all patients who had HAI were over 65 years old. The incidence rate of HAI in elderly patients was 1.2%, increasing with age. The most common types of HAIs were surgical site infections, septicemia, lower respiratory tract infections and urinary tract infections.

Abstract
OBJECTIVE The purpose of this study was to determine whether postoperative pain intensity differs between elderly abdominal surgery patients in whom postoperative pulmonary complications (PPC) develop and those in whom they do not. METHODS The exploratory secondary analysis of data from a prospective study of risk factors for PPC had a convenience sample of 86 patients (> or =60 years old) after abdominal surgery at 3 Midwestern hospitals. Daily measurements from postoperative day (POD) 1 to 6 included: pain (rated 0 to 10) at rest, with coughing, deep breathing, movement and walking, and frequency of ambulation. RESULTS Sixteen subjects (18.6%) had a PPC develop. Subjects with PPCs had higher mean pain intensities on all measures on each POD than those without. Those with PPCs had significantly higher pain intensities at rest on POD4 (P = .010), with deep breathing on POD2 (P = .015), POD4 (P = .009), POD5 (P = .006), and POD6 (P = .009), were up to a chair significantly fewer times on POD2 (P = .043), and walked significantly fewer times on POD5 (P = .002) and POD6 (P = .000) than those without PPCs. Length of stay for those with PPCs (mean, 17.9 days; standard deviation, 15.9 days; median, 10.0 days) was significantly longer than for those without PPCs (mean, 8.5 days; standard deviation, 4.8 days; median, 7.0 days; P = .000). CONCLUSION Results provide support for viewing pain as a factor that contributes to the development of PPCs among the elderly population after abdominal surgery. Therefore, nursing interventions of pain assessment and management, deep breathing, and ambulation may influence the incidence of this outcome.

Abstract
A total of 73 clinical isolates of Clostridium difficile isolated from stool/rectal swabs of patients admitted to the intensive care units at Mubarak Hospital, Ibn Sina Hospital Burn unit and Haematology wards at the Kuwait Cancer Control Centre, were investigated for their susceptibility to 15 antibiotics using the Etest. Amoxycillin-clavulanic acid, ampicillin, meropenem, metronidazole, penicillin, piperacillin, piperacillin/tazobactam, teicoplanin and vancomycin had excellent activities with MIC(90)s of 0.38, 0.5, 1, 0.19, 1.5, 2, 3, 0.25 and 0.75 mg/l, respectively. Of the 73 C. difficile isolates, 86% were resistant to imipenem (MIC(90) >32 mg/l) and almost 97% were resistant to trovafloxacin (MIC(90)>256 mg/l). Forty eight percent of the isolates were resistant to clindamycin. A total of 18 isolates were highly clindamycin-resistant with an MIC of >256 mg/l; 10 of these were toxin producers. Multiple antibiotic resistance (two or more antibiotics) was noted in 63 isolates. These were more common among the toxigenic strains than the non-toxigenic strains by a ratio of 2.5:1.

Abstract
Since the 1980s, methicillin-resistant Staphylococcus aureus (MRSA) has been identified as a significant infectious agent with an increasing incidence within both hospitals and the community. The aim of this study was to measure the incidence of MRSA colonization in patients admitted with a neck of femur fracture requiring implant surgery and to assess the outcome of these cases. We also sought to identify any risk factors associated with MRSA colonization, and to assess the need for any prophylactic treatment to prevent postoperative MRSA infection. Nasal, perineal and (where present) wound site swabs were taken on a sequential series of patients admitted with a neck of femur fracture who required a surgical implant. The presence of MRSA isolates from these swabs and the presence of a significant postoperative infection in both the colonized and non-colonized patients were recorded. A total of 66 patients were enrolled in the study, of whom 63 had surgical treatment for their fracture. A total of four patients were found to be colonized with MRSA. Of the study group, 27 patients had been admitted to hospital in the previous year, three of whom were found to be colonized with MRSA. Four of the patients were noted to have a postoperative infection-all of these cases were in the non-colonized group. The incidence of MRSA colonized patients in this series was 6%-a figure broadly consistent with previous studies. This does not appear to justify the routine screening of all neck of femur fracture admissions, though the results do suggest that a selective policy of screening only those who patients who had been admitted to hospital within the last year may be profitable. Our study does not appear to show any correlation between MRSA colonization and postoperative infection however. This is consistent with previous studies and does not support the adoption of an aggressive strategy for detection or eradication of MRSA prior to neck of femur fracture surgery.

Abstract
The Patient Treatment File (PTF) of the Department of Veterans Affairs (VA) comprises the computerized records of all inpatients treated at all VA hospitals throughout the United States. The database was utilized to study the clinical epidemiology and impact of C. difficile colitis on health care among hospitalized US military veterans. The computerized medical records of 15,091 cases with C. difficile colitis and 61,931 controls without the diagnosis were extracted from the annual files between 1993 and 1998. Of all patients admitted to the hospital, 1% were diagnosed with C. difficile colitis, in 16% of whom it was listed as the primary discharge diagnosis. C. difficile colitis was more likely to occur in elderly white patients with multiple comorbid conditions. Compared with a control population of hospitalized patients without C. difficile colitis, the case population was subjected to more medical and surgical procedures and experienced longer hospital stays. The diagnosis of C. difficile colitis was associated with more frequent admissions to the intensive care unit and higher hospital-related and subsequent mortality. Eleven percent of the cases were admitted to hospital a second time after a mean of 202 days, 2.5% were readmitted a third time after an additional 182 days, and 0.8% were readmitted a fourth time after an additional 194 days. In conclusion, as old age, multiple comorbid conditions, a high number of medical and surgical intervention, and long hospitalization constitute the main risk factors for the development of C. difficile colitis, efforts at prevention should be directed primarily towards patients who present with these characteristics.

Abstract
OBJECTIVE This study examined health and behavioral risk factors for infections that required hospitalization in postmenopausal women who were enrollees of a large health maintenance organization (HMO). METHODS Participants were 1,365 generally healthy women aged 55 to 80 years who were followed for up to 6 years. Infection diagnoses listed first in the automated hospital discharge records were used to identify hospitalizations for which infections were the primary cause of admission. Potential risk factors for these serious infections were identified from baseline questionnaire information and automated HMO records from before baseline and during follow-up. Risks for infections associated with hospital admission were examined using multivariate logistic regression methods. RESULTS Seventy-three women had a total of 90 hospital admissions in which infection was the primary discharge diagnosis. Behaviors that were independent predictors of infection were physical inactivity (adj. odds ratio = 4.08; 95% CI, 1.73-9.63) and smoking (adj. odds ratio = 2.64; 95% CI, 1.11-6.26). Incident cancer and lung disease were also associated with increased risk of infection. These associations were independent of age, body mass index, functional status, and other measures of health. CONCLUSIONS Modifiable risk factors such as physical inactivity and smoking may place older women at risk for serious infections although the causal link is yet to be explained. Further research in this area may lead to new strategies aimed at reducing the serious burden of infections in the older population.

Abstract
Point prevalence studies of hospital-acquired infections among the elderly in 65-70 long-term care facilities (LTCF) were carried out once a year over a three-year period in Oslo city, Norway. They showed an overall rate of 6.5% of hospital-acquired infections among 13 762 residents. The infection rate was approximately the same as in hospitals and twice as high as among hospitalized long-term psychiatric patients. Residents who had received surgical treatment within the previous three months had a high rate of postoperative infections, especially wound infections (14.8%). During the study period, the LTCFs were found to be understaffed and overcrowded. They had few private rooms, a lack of bathrooms and toilets, no isolation facilities and deficient ventilation systems. The economic consequences of hospital-acquired infections in these LTCFs were extra costs in medical and nursing care and antibacterial treatment of 157 500 Nkr/day (22500 USD). There would be a substantial cost-benefit in effective preventive measures against hospital-acquired infections in long-term care institutions.

Abstract
Continuous data collection on all new isolates of MRSA via CoSurv has taken place in Wales since January 1996. In order to audit this data collection, and to address some of the issues that it does not include, a survey of MRSA was carried out. Questionnaires were completed by infection control teams. Rates were calculated using hospital throughput denominators. Results from the one-day prevalence survey, the two-week incidence survey, and the follow-up survey carried out on new MRSA patients identified in the incidence survey, are presented. Results were found to be broadly similar to those collected via routine surveillance. MRSA was found frequently and disproportionately in the elderly, with higher rates in male than female patients. The highest incidence of total and invasive MRSA was in males aged 75 and over (total: 12.5/1000 finished consultant episodes; invasive: 2.8/1000). Although there was a large community reservoir of MRSA, most appeared to have been acquired in hospital, since most patients had a history of hospitalization, often with multiple hospital admissions. Community-based isolates from cases with no hospital history tended to have been from ulcers. Prevalence and incidence of MRSA was relatively low compared with hospital throughput (mean prevalence: 2.4/100 occupied beds; mean incidence: 3.6/1000 finished consultant episodes), there was also quite large variation between sites, even when screening samples were removed. Patients with MRSA had strikingly long stays before isolation of the organism (prevalence survey: 39 days; incidence survey: 31 days) and highest incidence occurred in elderly care wards. The outcome survey showed that approximately half of the patients were treated with some type of antimicrobial therapy for MRSA. Decontamination therapy was associated with clearance of MRSA only when controlling for sex of the patient. The majority of patients were discharged still with MRSA, mostly to their own homes. The survey emphasizes the need to continue surveillance to detect any changes, to allow guidelines based on evidence to be developed and to monitor the effectiveness of such guidelines.

Abstract
A prevalence study of methicillin-resistant Staphylococcus aureus (MRSA) colonization was carried out in 17 nursing homes in Northamptonshire over a 20-month period. Thirteen of 275 residents swabbed (4.7%) were found to be colonized and six of the 17 homes (35%) had colonized residents. Only two homes had more than one colonized resident. Individual risk factors for colonization were gender (male) and the presence of skin ulcers and sores. There were no significant risk factors identified for homes. Spread may have occurred in the two homes which had more than one colonized resident. Both these homes had the epidemic strain EMRSA-15 whereas three of the four homes with a single colonized resident had EMRSA-16. It is suggested that homes with residents colonized with EMRSA-16 may be able to prevent spread by adherence to good infection control procedures but that this may not be adequate to prevent spread of EMRSA-15.
