RESUMO
BACKGROUND: Point prevalence surveys are an important surveillance method for determining the burden of healthcare-associated infections (HCAIs). AIM: To outline the key results of two point prevalence surveys in England (2011 and 2016). METHODS: All National Health Service and independent sector hospitals in England were eligible to participate. Data were collected between September and November in both 2011 and 2016 based on the protocol and codebook devised by the European Centre for Disease Prevention and Control. Analysis was performed using Stata Version 13 and SAS Version 9.3. A mixed-effects model was applied, which allowed estimation of organization-specific means and accounted for the heterogeneity in the responses from different organizations. FINDINGS: A total of 100,755 case records were included (52,433 in 2011 and 48,312 in 2016). The estimated prevalence of HCAIs was slightly higher in 2016 [6.89%, 95% confidence interval (CI) 6.21-7.57%] than in 2011 (6.41%, 95% CI 5.75-7.06%). In both surveys, the prevalence of HCAIs was highest in adult intensive care units (23.1% in 2011, 21.2% in 2016), and pneumonia/lower respiratory tract infections was the most common cause of HCAIs (22.7% in 2011 vs 29.2% in 2016). Inpatients in acute hospitals were older and had higher risk of dying in 2016 compared with 2011; however, the proportion of inpatients with HCAIs or on antibiotics did not differ significantly. CONCLUSION: The burden of HCAIs in English hospitals increased slightly between 2011 and 2016. However, the proportion of inpatients with HCAIs or on antibiotics did not differ significantly.

Robots designed to elicit sexual arousal are coming. Sexual arousal can increase our willingness to engage in risky or unconventional sexual behaviors. However, researchers have yet to examine whether this effect extends to robots. Hence, this study provides the first empirical evidence that state sexual arousal can increase our willingness to engage erotically with robots. Based on previous research, we hypothesized that levels of sexual arousal would positively predict willingness to engage erotically with robots (Hypothesis 1); and that men would be more willing to engage erotically with robots than women (Hypothesis 2). A convenience sample of 321 adults (≥18y) completed a two-part online survey measuring their willingness to have sex with, love, engage in an intimate relationship with, and be friends with a robot and a human before and after viewing a sexually explicit video. The results partly support Hypotheses 1-2. They show that state sexual arousal increases willingness to have sex with a robot, and that men are more willing to have sex and engage in an intimate relationship with a robot than women, pre- and post-manipulation. These findings are important given the rise of sex robots and their potential influence on our intimate decisions and behaviors.
RESUMO
OBJECTIVE: To assess the incidence of maternal group B Streptococcus (GBS) infection in England. DESIGN: Population surveillance augmented through data linkage. SETTING: England. POPULATION: All pregnant women accessing the National Health Service (NHS) in England. METHODS: Invasive GBS (iGBS) infections during pregnancy or within 6 weeks of childbirth were identified by linking Public Health England (PHE) national microbiology surveillance data for 2014 to NHS hospital admission records. Capsular serotypes of GBS were determined by reference laboratory typing of clinical isolates from women aged 15-44 years. Post-caesarean section surgical site infection (SSI) caused by GBS was identified in 21 hospitals participating in PHE SSI surveillance (2009-2015). MAIN OUTCOME MEASURES: iGBS rate per 1000 maternities; risk of GBS SSI per 1000 caesarean sections. RESULTS: Of 1601 patients diagnosed with iGBS infections in England in 2014, 185 (12%) were identified as maternal infections, a rate of 0.29 (95% CI 0.25-0.33) per 1000 maternities and representing 83% of all iGBS cases in women aged 18-44 years. Seven (3.8%) were associated with miscarriage. Fetal outcome identified excess rates of stillbirth (3.4 versus 0.5%) and extreme prematurity (<28 weeks of gestation, 3.7 versus 0.5%) compared with national averages (P < 0.001). Caesarean section surveillance in 27 860 women (21 hospitals) identified 47 cases of GBS SSI, with an estimated 4.24 (3.51-5.07) per 1000 caesarean sections, a median time-to-onset of 10 days (IQR 7-13 days) and ten infections that required readmission. Capsular serotype analysis identified a diverse array of strains with serotype III as the most common (43%). CONCLUSIONS: Our assessment of maternal GBS infection in England indicates the potential additional benefit of GBS vaccination in preventing adverse maternal and fetal outcomes.

BACKGROUND: Bloodstream infections (BSIs) in patients in intensive care units (ICUs) are associated with increased morbidity, mortality and economic costs. Many BSIs are associated with central venous catheters (CVCs). The Infection in Critical Care Quality Improvement Programme (ICCQIP) was established to initiate surveillance of BSIs in English ICUs. METHODS: A web-based data capture system was launched on 1st May 2016 to collect all positive blood cultures (PBCs), patient-days and CVC-days. National Health Service (NHS) trusts in England were invited to participate in the surveillance programme. Data were linked to the antimicrobial resistance dataset maintained by Public Health England and to mortality data. FINDINGS: Between 1st May 2016 and 30th April 2017, 84 ICUs (72 adult ICUs, seven paediatric ICUs and five neonatal ICUs) based in 57 of 147 NHS trusts provided data. In total, 1474 PBCs were reported, with coagulase-negative staphylococci, Escherichia coli, Staphylococcus aureus and Enterococcus faecium being the most commonly reported organisms. The rates of BSI and ICU-associated CVC-BSI were 5.7, 1.5 and 1.3 per 1000 bed-days and 2.3, 1.0 and 1.5 per 1000 ICU-CVC-days in adult, paediatric and neonatal ICUs, respectively. There was wide variation in BSI and CVC-BSI rates within ICU types, particularly in adult ICUs (0-44.0 per 1000 bed-days and 0-18.3 per 1000 ICU-CVC-days). CONCLUSIONS: While the overall rates of ICU-associated CVC-BSIs were lower than 2.5 per 1000 ICU-CVC-days across all age ranges, large differences were observed between ICUs, highlighting the importance of a national standardized surveillance system to identify opportunities for improvement. Data linkage provided clinically important information on resistance patterns and patient outcomes at no extra cost to participating trusts.

Humans can anticipate music and derive pleasure from it. Expectations facilitate the learning of movements associated with anticipated events, and they are also linked with reward, which may further facilitate learning of the anticipated rewarding events. The present study investigates the synergistic effects of predictability and hedonic responses to music on arousal and motor-learning in a naïve population. Novel melodies were manipulated in their overall predictability (predictable/unpredictable) as objectively defined by a model of music expectation, and ranked as high/medium/low liked based on participants' self-reports collected during an initial listening session. During this session, we also recorded ocular pupil size as an implicit measure of listeners' arousal. During the following motor task, participants learned to play target notes of the melodies on a keyboard (notes were of similar motor and musical complexity across melodies). Pupil dilation was greater for liked melodies, particularly when predictable. Motor performance was facilitated in predictable rather than unpredictable melodies, but liked melodies were learned even in the unpredictable condition. Low-liked melodies also showed learning but mostly in participants with higher scores of task perceived competence. Taken together, these results highlight the effects of stimuli predictability on learning, which can be however overshadowed by the effects of stimulus liking or task-related intrinsic motivation.

Anesthesia of the horn bud for calf disbudding commonly is attained by injection of local anesthetic over branches of the cornual nerve, with anesthesia achieved in 3 to 20 min. With experienced and trained staff, this method is effective in 88 to 100% of calves. Variability in response and time of onset can compromise calf welfare if calves are disbudded before anesthesia is attained. Proposed legislative reliance on effective local anesthetic as the minimal method of pain relief for calves at disbudding means that administration of local anesthetic must achieve a repeatable level and rapid onset of analgesia. We describe an alternative method of local anesthesia administration that uses local site infiltration of anesthetic over the horn bud. However, this method has not yet been scientifically validated. This study assessed differences between disbudding using the cornual nerve block and disbudding with local anesthesia administered by local site infiltration. Efficacy of local anesthesia was assessed at 30-s intervals after administration by absence of reaction to 3 consecutive needle pricks over the horn buds. Behavior indicating pain was assessed during disbudding and scored from 0 to 3. Calf behavior was also recorded for 3 h after disbudding. Accelerometer data loggers were fitted to each calf for 24 h before and after disbudding to assess lying and standing times. Median time to cutaneous desensitization for local infiltration was 60 s compared with 225 s for cornual nerve block, and the variance in time to desensitization was less with local infiltration. Calves disbudded under cornual block had a larger behavioral response (indicated by a graded aversive body reaction) than calves disbudded under local infiltration. A multivariable model predicted that the mean body reaction score would be 0.6 for calves disbudded under local infiltration and 1.2 for calves disbudded under cornual block. There was no difference in any behaviors between the treatment groups in the 3 h after disbudding. Method of analgesia had no effect on lying time over the 24 h after disbudding. In this study, local infiltration was at least as effective in providing analgesia for disbudding as the cornual nerve block. Our results suggest that a more consistent, effective level of analgesia during disbudding was achieved using local infiltration and that there was no difference in postoperative expressions of pain.

BACKGROUND: An electronic reporting system (ERS) for the enhanced surveillance of carbapenemase-producing Gram-negative bacteria (CPGNB) was launched by Public Health England in May 2015. AIM: This evaluation aimed to assess uptake, timeliness and completeness of data provided and explore potential barriers and facilitators to adopting the system. METHODS: The evaluation comprised a retrospective analysis of surveillance data and semi-structured interviews with ERS users. FINDINGS: The proportion of organisms referred for investigation of carbapenem resistance via ERS increased over the first 12â¯months post-implementation from 35% to 73%; uptake varied widely across regions of England. Completeness of enhanced data fields was poor in 78% of submitted isolates. The median number of days to report confirmatory test results via ERS was 1â¯day for the regional service and nine days for the national reference laboratory, which additionally conducts phenotypic testing to confirm carbapenemase negativity. Hindrances to ERS utility included: a lack of designated, ongoing resource for system maintenance, technical support and development; uncertainty about how and when to use ERS and workload. Incomplete data prevented gaining a better understanding of important risk factors and transmission routes of CPGNB in England. CONCLUSION: The ERS is the only surveillance system in England with the potential to gather intelligence on important risk factors for CPGNB to inform public health measures to control their spread. Although the ERS captures more information on CPGNB than other surveillance systems, timeliness and completeness of the enhanced data require substantial improvements in order to deliver the desired health benefits.

BACKGROUND: The incidence of Escherichia coli bacteraemia in England is increasing amid concern regarding the roles of antimicrobial resistance and nosocomial acquisition on burden of disease. AIM: To determine the relative contributions of hospital-onset E. coli bloodstream infection and specific E. coli antimicrobial resistance patterns to the burden and severity of E. coli bacteraemia in West London. METHODS: Patient and antimicrobial susceptibility data were collected for all cases of E. coli bacteraemia between 2011 and 2015. Multivariable logistic regression was used to determine the association between the category of infection (hospital or community-onset) and length of stay, intensive care unit admission, and 30-day all-cause mortality. FINDINGS: E. coli bacteraemia incidence increased by 76% during the study period, predominantly due to community-onset cases. Resistance to quinolones, third-generation cephalosporins, and aminoglycosides also increased over the study period, occurring in both community- and hospital-onset cases. Hospital-onset and non-susceptibility to either quinolones or third-generation cephalosporins were significant risk factors for prolonged length of stay, as was older age. Rates of mortality were 7% and 12% at 7 and 30 days, respectively. Older age, a higher comorbidity score, and bacteraemia caused by strains resistant to three antibiotic classes were all significant risk factors for mortality at 30 days. CONCLUSION: Multidrug resistance, increased age, and comorbidities were the main drivers of adverse outcome. The rise in E. coli bacteraemia was predominantly driven by community-onset infections, and initiatives to prevent community-onset cases should be a major focus to reduce the quantitative burden of E. coli infection.

OBJECTIVE: Ankle sprains are common injuries that may lead to long-term morbidity. Individuals with obesity are at increased risk for ankle sprains; however, prognostic associations between body mass index (BMI) and recovery are less well understood. This study investigated whether BMI status affects recovery from ankle sprains. METHODS: We included individuals≥16 years old with grade 1 or 2 ankle sprains who sought emergency department treatment in Kingston, Ontario, Canada. Height in centimeters and weight in kilograms were measured at baseline by using a height rod and a standard medical column scale, respectively. BMI was calculated and categorized as non-overweight,<25.0kg/m2; overweight, 25.0-29.9kg/m2; and obese,≥30kg/m2. Recovery was assessed at 1, 3 and 6 months post-injury by the Foot and Ankle Outcome Score (FAOS). Continuous FAOS and binary recovery status were compared by BMI group at each assessment using a repeated measures linear mixed effects model and logistic regression, respectively. RESULTS: In total, 504 individuals were recruited and 6-month follow-up data were collected for 80%. We observed no significant differences in recovery at 1 and 3 months post-injury. At 6 months, between 53% and 66% of the participants were considered to have recovered according to the FAOS. The mean difference in unadjusted FAOS between participants classified as obese and non-overweight was -23.02 (95% confidence interval, -38.99 to -7.05) but decreased after adjusting for confounders. The odds ratio for recovery was 0.60 (0.37-0.97) before adjustment and 0.74 (0.43-1.29) after adjustment. Six-month recovery was significantly lower for participants with obesity than non-overweight participants on the FAOS Pain and Function in Daily Living subscales but were not clinically meaningful. CONCLUSIONS: All BMI groups showed improvements from ankle sprain over time. However, at 6 months, a sizeable proportion of the participants had not fully recovered particularly among individuals classified as obese. The findings suggest that individuals with obesity may benefit from specialized interventions focused on symptom management and functional activity.

BACKGROUND: The rise in antimicrobial resistance has highlighted the importance of surgical site infection (SSI) prevention with effective surveillance strategies playing a key role in improving patient safety. AIM: To map national needs and priorities for SSI surveillance against current national surveillance activity. METHODS: This study analysed SSI surveillance in National Health Service (NHS) hospitals in England covering 23 surgical procedures. Data collected were: (i) annual number of procedures, (ii) SSI rates from national reports, (iii) national reporting requirement (mandatory, voluntary, not offered), (iv) priority ranking from a survey of 84 English NHS hospitals, (v) excess length of stay and costs from the literature. The relationships between estimated SSI burden, national surveillance activity, and hospital-reported priorities were explored with descriptive and univariate analyses. FINDINGS: Among the 23 surgical categories analysed, top priority ranking by hospitals was associated only with current surveillance (r = 0.76, P < 0.01) and mandatory reporting (33% vs 8 and 4%, P = 0.04). Percentage of hospitals undertaking surveillance, mandatory reporting, and the selection of priorities did not match SSI burden. Large bowel surgery (LBS, voluntary) and caesarean section (not offered) were the two highest contributors of total SSIs per annum, with 39,000 (38%) and 17,000 (16%) respectively, while the four orthopaedic categories (all mandatory) contributed 5000 (5%). LBS also had the highest associated costs (£119 million per annum). CONCLUSION: Current surveillance and future priorities were not associated with SSI rate, volume, or cost to hospitals. The two highest contributors of SSIs and related costs have no (caesarean section) or limited (LBS) coverage by national surveillance.

BACKGROUND: Since the launch of the national Surgical Site Infection (SSI) Surveillance Service in 1997, successive expansions of the programme provided hospitals with increasing flexibility in procedures to target through surveillance. Ensuring that the programme continues to meet hospitals' needs remains essential. AIM: As a means to inform the future direction of the service, a survey of all acute National Health Service trusts was undertaken to assess and understand priorities for surveillance. METHODS: A web-based survey was circulated to acute NHS trust infection control teams in England, asking them to identify and rank (i) reasons for undertaking current SSI surveillance, (ii) priority surgical categories for future SSI surveillance, and (iii) reasons for prioritizing these categories. FINDINGS: Of the 161 trusts surveyed, 84 (52%) responded. Assessment of quality of care was identified as the most common driver for SSI surveillance activity. Considerable heterogeneity in priority areas was observed, with 24 different surgical categories selected as top priority. Of the procedures undertaken by 15 or more trusts, caesarean section (2.7), hip replacement (2.8) and coronary artery bypass graft (2.9) were highest ranked. All 17 categories in the current surveillance programme were selected as a top priority by one or more trusts. CONCLUSION: Whereas the majority of hospitals' priorities for SSI surveillance are included in the current programme, the top-ranked priority, caesarean section, is not included. Given the diversity of priority areas, maintaining a comprehensive spectrum of categories in the national programme is essential to assist hospitals in addressing local priorities.

BACKGROUND: Following hospital outbreaks of carbapenemase-producing Enterobacteriaceae (CPE), Public Health England published a toolkit in December 2013 to promote the early detection, management, and control of CPE colonization and infection in acute hospital settings. AIM: To examine awareness, uptake, implementation and usefulness of the CPE toolkit and identify potential barriers and facilitators to its adoption in order to inform future guidance. METHODS: A cross-sectional survey of National Health Service (NHS) acute trusts was conducted in May 2016. Descriptive analysis and multivariable regression models were conducted, and narrative responses were analysed thematically and informed using behaviour change theory. FINDINGS: Most (92%) acute trusts had a written CPE plan. Fewer (75%) reported consistent compliance with screening and isolation of CPE risk patients. Lower prioritization and weaker senior management support for CPE prevention were associated with poorer compliance. Awareness of the CPE toolkit was high and all trusts with patients infected or colonized with CPE had used the toolkit either as provided (32%), or to inform (65%) their own local CPE plan. Despite this, many respondents (80%) did not believe that the CPE toolkit guidance offered an effective means to prevent CPE or was practical to follow. CONCLUSION: CPE prevention and control requires robust IPC measures. Successful implementation can be hindered by a complex set of factors related to their practical execution, insufficient resources and a lack of confidence in the effectiveness of the guidance. Future CPE guidance would benefit from substantive user involvement, processes for ongoing feedback, and regular guidance updates.

Escherichia coli bacteraemia rates have been increasing in England. Using the national mandatory surveillance data for E. coli bacteraemia from 2012/13 to 2016/17, we aimed to estimate the incidence of E. coli bacteraemia and 30-day all-cause case fatality rate (CFR) by 2020/21 in the absence of new interventions to reduce infection rates. After controlling for age, sex, and hospital versus community-onset of infection, it is estimated that the incidence of E. coli bacteraemia will be 90.5 (95% PI: 89.8-91.3) per 100,000 population (N = 50,663), with an associated CFR of 11.5 (95% PI: 11.2-11.8) per 100,000 population (N = 6554), by 2020/21.

BACKGROUND: A national voluntary surveillance programme has shown year-on-year increases in the number of bacteraemias caused by Escherichia coli. Mandatory surveillance of E. coli bacteraemia was introduced in 2011 with the aim of improving the quantity and quality of data collected. In contrast to the other national mandatory surveillance programmes, cases are not currently categorized based upon time of onset in relation to hospital admission. AIM: To assess the case for applying time-of-onset categorization to cases of E. coli bacteraemia in England. METHODS: Data for all cases of E. coli bacteraemia reported to Public Health England between April 2012 and March 2016 were extracted from the national mandatory surveillance database. Cases were categorized as hospital-onset if positive blood cultures were obtained two or more days after admission. RESULTS: Approximately 21% of cases were categorized as hospital-onset. However, the proportion of hospital-onset cases decreased by 1% in each successive 12-month period, from 23% in 2012/13 to 20% in 2015/16 (P<0.001). CONCLUSIONS: Approximately one-fifth of E. coli bacteraemia cases reported via mandatory surveillance were identified as hospital-onset. Given that prevention and control strategies will vary by setting, the routine feedback of this information will prove important in informing infection prevention and control efforts. The categorization of this subset of cases represents an important step towards better understanding of the epidemiology of E. coli bacteraemia.

BACKGROUND: Escherichia coli causes more than one-third of the bacteraemia cases in England each year, and the incidence of these infections is increasing. AIM: To determine the underlying risk factors associated with E. coli bacteraemia. METHODS: A three-month enhanced sentinel surveillance study involving 35 National Health Service hospitals was undertaken in the winter of 2012/13 to collect risk factor information and further details on the underlying source of infection to augment data already collected by the English national surveillance programme. Antimicrobial susceptibility results for E. coli isolated from blood and urine were also collected. FINDINGS: A total of 1731 cases of E. coli bacteraemia were included. The urogenital tract was the most frequently reported source of infection (51.2% of cases) with previous treatment for a urinary tract infection being the largest independent effect associated with this infection source. Half of all patients had previous healthcare exposure in the month prior to the bacteraemia with antimicrobial therapy and urinary catheterization being reported in one-third and one-fifth of these patients, respectively. Previous healthcare exposure was associated with a higher proportion of antibiotic non-susceptibility in the blood culture isolates (P=0.001). CONCLUSION: Analysis of risk factors suggests the potential benefit of community- and hospital-related interventions, especially the better use of urinary catheters and improved antibiotic management of urinary tract infections. As part of the latter strategy, antibiotic resistance profiles need to be closely monitored to ensure that treatment guidelines are up to date to limit inappropriate empiric therapy.

PurposeLow-vision clients frequently report having problems with reading. Using magnification, reading performance (as measured by reading speed) can be improved by up to 200%. Current magnification aids can be expensive or bulky; therefore, we explored if the Apple iPad offers comparable performance in improving reading speeds, in comparison with a closed-circuit television (CCTV) video magnifier, or other magnification devices.MethodsWe recruited 100 participants between the ages of 24-97 years, with low vision who were literate and cognitively capable, of whom 57 had age-related macular degeneration. To assess reading, participants read standardized iReST texts and were tested for comprehension. We compared reading speed on the Apple iPad (10 inch) with that of the CCTV, home magnification devices, and baseline measures.ResultsAll assistive devices improved reading rates in comparison to baseline (P<0.001, Hedge's g>1), however, there was no difference in improvement across devices (P>0.05, Hedge's g<0.1). When experience was taken into account, those with iPad experience read, on average, 30 words per minute faster than first time iPad users, whereas CCTV experience did not influence reading speed.ConclusionsIn our sample, the Apple iPad was as effective as currently used technologies for improving reading rates. Moreover, exposure to, and experience with the Apple iPad might increase reading speed with that device. A larger sample size, however, is needed to do subgroup analysis on who would optimally benefit from each type of magnification device.

BACKGROUND: Geographic variation in cancer care is common when clear clinical management guidelines do not exist. In the present study, we sought to describe health care resource consumption by patients with metastatic gastric cancer (gc) and to investigate the possibility of regional variation. METHODS: In this population-based cohort study of patients with stage iv gastric adenocarcinoma diagnosed between 1 April 2005 and 31 March 2008, chart review and administrative health care data were linked to study resource utilization outcomes (for example, clinical investigations, treatments) in the province of Ontario. The study took a health care system perspective with a 2-year time frame. Chi-square tests were used to compare proportions of resource utilization, and analysis of variance compared mean per-patient resource consumption between geographic regions. RESULTS: A cohort of 1433 patients received 4690 endoscopic investigations, 12,033 computed tomography exams, 12,774 radiography exams, and 5059 ultrasonography exams. Nearly all patients were seen by a general practitioner (98%) and a specialist (99%), and were hospitalized (95%) or visited the emergency department (87%). Fewer than half received chemotherapy (43%), gastrectomy (37%), or radiotherapy (28%). The mean number of clinical investigations, physician visits, hospitalizations, and instances of patient accessing the emergency department or receiving radiotherapy or stent placement varied significantly by region. CONCLUSIONS: Variations in health care resource utilization for metastatic gc patients are observed across the regions of Ontario. Whether those differences reflect differential access to resources, patient preference, or physician preference is not known.
