RESUMO
Systemic anaplastic large-cell lymphoma (sALCL) is a rare T-cell lymphoma associated with poor prognosis after relapse. The immunoconjugate brentuximab vedotin (BV) first became available for relapsed sALCL in England in 2013, following the results of a pivotal phase II study. We present a population-based study describing outcomes of relapsed sALCL in England after BV, using Public Health England data. We obtained information on all relapsed/refractory (r/r) sALCL patients ≥18 years treated with BV monotherapy in England between 1 January 2014 and 31 December 2019. The final cohort comprised 127 patients with a median age of 60 years (range 19-89). Eighteen (14·2%) had received stem cell transplant in first remission. Median two-year overall survival (OS) was 46·6%. The vast majority of deaths (59) occurred within 18 months, with very few events after this. Receipt of BV as second line compared to third or fourth line was associated with significantly improved survival (two-year OS 50·3% vs 29·7%, P = 0·03). There was no difference in OS for different subgroups, including anaplastic lymphoma kinase status, age, gender, or receipt of stem cell transplantation in first response. We report excellent survival following treatment with BV in a real-world setting, comparable with previous clinical trial data.

BACKGROUND: Findings are presented from the evaluation of Public Health England's (PHE) Prioritization Framework (PF) aimed to assist local authority commissioners with their public health investment and disinvestment decisions. The study explored the take up of the PF in three early adopter local authority settings. METHODS: Semi-structured interviews (n = 30) across three local authorities supplemented by participant observation of workshops. RESULTS: Participants acknowledged that the PF provided a systematic means of guiding priority-setting and one that encouraged transparency over investment and disinvestment decisions. The role performed by PHE and its regional teams in facilitating the process was especially welcomed and considered critical to the adoption process. However, uptake of the PF required a significant investment of time and commitment from public health teams at a time when resources were stretched. The impact of the political environment in the local government was a major factor determining the likely uptake of the PF. Ensuring committed leadership and engagement from senior politicians and officers was regarded as critical to success. CONCLUSIONS: The study assessed the value and impact of PHE's PF tool in three early adopter local authorities. Further research could explore the value of the tool in aiding investment and disinvestment decisions and its impact on spending.

OBJECTIVES: The aim of the study was to identify care home characteristics associated with reported care home influenza outbreaks and factors associated with increased transmission of influenza-like illness (ILI) in care homes in Cheshire and Merseyside during the 2017-2018 influenza season. STUDY DESIGN: This is a matched case-control study comparing characteristics between care homes with and without a declared influenza outbreak and a retrospective risk factor analysis of care home residents with ILI. METHODS: Routinely collected outbreak surveillance data on symptomatic residents and staff, antiviral prophylaxis and influenza vaccination history, which were reported to Public Health England, were extracted from health protection electronic records. Further care home characteristics were extracted from the Care Quality Commission (CQC) website. Care homes with declared influenza outbreaks were matched with care homes without outbreaks. Chi-squared tests and logistic regression were used to examine associations between care home factors and ILI. RESULTS: There were no significant differences in characteristics between 77 care homes with declared influenza outbreaks and 77 matched care homes without outbreaks. Of 2,744 residents from the homes with a declared outbreak, 644 (24%) developed an ILI. The care home risk factors were having a low CQC score and activation of antiviral prophylaxis and the protective factors were having higher numbers of residents, specializing in dementia care and having the highest CQC score. Significantly more cases occurred in residential homes than in nursing homes, in homes with lower CQC scores and in homes where eligible residents were given antiviral prophylaxis. CONCLUSIONS: In homes with declared outbreaks, certain characteristics including activation of antiviral prophylaxis were associated with an increased risk of ILI. Further research is needed, particularly focussing on temporality between provision of prophylactic antivirals and the onset of ILI.

OBJECTIVES: To assess the association of antiviral prophylaxis and care home characteristics with the spread and severity of influenza-like illness in care homes with influenza outbreaks in North West England in the 2017/2018 influenza season. STUDY DESIGN: This is a retrospective observational study. METHODS: Routinely collected outbreak surveillance data reported to Public Health England were extracted from health protection electronic records. Data included use of antiviral prophylaxis, influenza-like illness or confirmed influenza, hospital admissions and deaths. Care home characteristics were obtained from the Care Quality Commission website. Single variable analysis and multivariable logistic regression were used to examine associations between care home characteristics, antiviral prophylaxis and influenza-related outcomes. RESULTS: In the 109 homes, there were 3498 residents; of whom, 855 (24%) developed an influenza-like illness. Antiviral prophylaxis was given to residents of 67 of the 109 care homes with outbreaks (61%). A significantly higher attack rate was observed among residents of homes given antiviral prophylaxis (27%) than among residents of homes not given antivirals (20%) (P < 0.001). Significantly more deaths occurred in homes for people with learning disabilities and homes that received antiviral prophylaxis (P < 0.001). CONCLUSIONS: In homes given antiviral prophylaxis, there were a higher number of residents with influenza-like illness and deaths. To improve our understanding of the impact of antiviral prophylaxis use in real life, enhanced and timely data collection is needed for identification of temporal associations between exposure and administration of antiviral prophylaxis. Consideration needs also to be given to ensure people with learning disabilities are protected through the seasonal influenza vaccine and timely antiviral prophylaxis when appropriate.

INTRODUCTION: An unprecedented global effort has been required to tackle the Ebola outbreak in West Africa. In this paper, we describe the contribution of Public Health England (PHE) in West Africa and the UK. SOURCES OF DATA: Public Health England AREAS OF AGREEMENT: The epidemic has been a humanitarian crisis for the three worst affected countries. PHE contributions have included expertise in outbreak control and microbiology services in West Africa, and UK preparedness for an imported case. AREAS OF CONTROVERSY: National and international systems require change to enhance the response to the next international public health crisis. GROWING POINTS: Legacy planning following the epidemic will be crucial, supporting the recovery of the health and public health systems in West Africa and ensuring that the knowledge gained during this outbreak is put to best use. AREAS TIMELY FOR DEVELOPING RESEARCH: Ongoing PHE-associated research includes efforts to understand the pathogenicity of Ebola virus disease, improve diagnostic capability, explore therapeutic options and develop new vaccines.

Objectives: Bilateral Institutional Health Partnerships (IHPs) are a means of strengthening health systems and are becoming increasing prevalent in global health. Nigeria Centre for Disease Control (NCDC) and Public Health England (PHE) have engaged in one such IHP as part of Public Health England's International Health Regulations Strengthening project. Presently, there have been limited evaluations of IHPs resulting in limited evidence of their effectiveness in strengthening health systems despite the concept being used across the world. Study design: Qualitative, using a validated tool. Methods: The ESTHER EFFECt tool was used to evaluate the IHP between NCDC and PHE. Senior leadership from both organisations participated in a two-day workshop where their perceptions of various elements of the partnership were evaluated. This was done through an initial quantitative survey followed by a facilitated discussion to further explore any arising issues. Results: This evaluation is the first published evaluation of a bilateral global health partnership undertaken by NCDC and PHE. NCDC scores were consistently higher than PHE scores. Key strengths and weaknesses of the partnership were identified such as having wide ranging institutional engagement, however needing to improve dissemination mechanisms following key learning activity. Conclusions: There is a dearth of evidence measuring the effectiveness of international health partnerships; of the studies that exist, many are lacking in academic rigour. We used the ESTHER EFFECt tool as it is an established method of evaluating the progress of the partnership, with multiple previous peer-reviewed publications. This will hopefully encourage more organisations to publish evaluations of their international health partnerships and build the evidence base.
RESUMO
JUUL is a groundbreaking electronic cigarette (e-cig) and the preeminent vaping product on the market. We present an overview of the rapid and spectacular rise of JUUL and its remarkable fall within the timespan of 2015 - 2020. We highlight JUUL's entering the market in June 2015, becoming the industry leader in mid 2017, and experiencing a litany of setbacks by late 2019 through to early 2020. We address the role played by JUUL in the ongoing epidemic of youth vaping. We also feature competing views on the public health impact of JUUL use (in particular), and e-cig vaping (in general). We further highlight the latest trends in youth vaping and sales records for JUUL and tobacco cigarettes. In view of the ongoing pandemic of COVID-19, we briefly summarize the existing evidence on the relationship between vaping and smoking and the prevalence, disease course, and clinical outcomes of COVID-19.
RESUMO
Vaccine co-administration can facilitate the introduction of new vaccines in immunisation schedules and improve coverage. We analysed real life data to quantify the extent of routine paediatric vaccine co-administrations as recommended and as never recommended in the immunisation schedule in England, and assessed factors for recommended and never recommended vaccine co-administrations. Immunisation data for all scheduled routine paediatric vaccines between 2008 and 2018 was obtained from the Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC). We included 6'257'828 doses administered to 1'005'827 children. Twenty-one percent of vaccines were given separately, 79% were co-administered. Sixty-four percent of vaccines scheduled for co-administration were co-administered as recommended while 15% were administered separately. Among all vaccine co-administrations, 75% happened as recommended in the schedule, 4% were never recommended, while 21% deviated from the schedule. Vaccine co-administration according to the schedule varied greatly between vaccines. Forty-eight percent of English children received at least one of their vaccine co-administrations not as recommended in the immunisation schedule, with 19% of children receiving none of their co-administered vaccines as recommended. Late administration of one or more vaccines increased the odds for deviated co-administrations (OR 1.60) and strongly increased the odds for never recommended co-administrations (OR 5.34). Differences between genders, NHS regions, and IMD quintiles were statistically significant but small. Suboptimal co-administration rates for routine paediatric vaccines are a missed opportunity and should be optimised by concerted public health action.
RESUMO
UK Biobank (UKB) is an international health resource enabling research into the genetic and lifestyle determinants of common diseases of middle and older age. It comprises 500â000 participants. Public Health England's Second Generation Surveillance System is a centralized microbiology database covering English clinical diagnostics laboratories that provides national surveillance of legally notifiable infections, bacterial isolations and antimicrobial resistance. We previously developed secure, pseudonymized, individual-level linkage of these systems. In this study, we implemented rapid dynamic linkage, which allows us to provide a regular feed of new COVID-19 (SARS-CoV-2) test results to UKB to facilitate rapid and urgent research into the epidemiological and human genetic risk factors for severe infection in the cohort. Here, we have characterized the first 1352 cases of COVID-19 in UKB participants, of whom 895 met our working definition of severe COVID-19 as inpatients hospitalized on or after 16 March 2020. We found that the incidence of severe COVID-19 among UKB cases was 27.4â% lower than the general population in England, although this difference varied significantly by age and sex. The total number of UKB cases could be estimated as 0.6â% of the publicly announced number of cases in England. We considered how increasing case numbers will affect the power of genome-wide association studies. This new dynamic linkage system has further potential to facilitate the investigation of other infections and the prospective collection of microbiological cultures to create a microbiological biobank (bugbank) for studying the interaction of environment, human and microbial genetics on infection in the UKB cohort.

We sought to gain insights into the determinants of seasonal influenza vaccine (SIV) uptake by conducting an age-stratified analysis (18-64 and 65+) of factors associated with SIV uptake among at-risk adults registered to English practices. Records for at-risk English adults between 2011 and 2016 were identified using the Clinical Practice Research Datalink database. SIV uptake was assessed annually. The associations of patient, practice, and seasonal characteristics with SIV uptake were assessed via cross-sectional and longitudinal analyses, using mixed-effects and general estimating equation logistic regression models. Overall SIV uptake was 35.3% and 74.0% for adults 18-64 and 65+, respectively. Relative to white patients, black patients were least likely to be vaccinated (OR18-64: 0.82 (95% CI: 0.80, 0.85); OR65+: 0.59 (95% CI: 0.56, 0.62)), while Asian patients among 18-64 year olds were most likely to be vaccinated (OR18-64: 1.10 (95% CI: 1.07, 1.13)). Females were more likely than males to be vaccinated among 18-64 year olds (OR18-64: 1.19 (95% CI: 1.18, 1.20)). Greater socioeconomic deprivation was associated with decreased odds of uptake among older patients (OR65+: 0.74 (95% CI: 0.71, 0.77)). For each additional at-risk condition, odds of uptake increased (OR18-64: 2.33 (95% CI: 2.31, 2.36); OR65+: 1.39 (95% CI: 1.38, 1.39)). Odds of uptake were highest among younger patients with diabetes (OR18-64: 4.25 (95% CI: 4.18, 4.32)) and older patients with chronic respiratory disease (OR65+: 1.60 (95% CI: 1.58, 1.63)), whereas they were lowest among morbidly obese patients of all ages (OR18-64: 0.68 (95% CI: 0.67, 0.70); OR65+: 0.97 (95% CI: 0.94, 0.99)). Prior influenza season severity and vaccine effectiveness were marginally predictive of uptake. Our age-stratified analysis uncovered SIV uptake disparities by ethnicity, sex, age, socioeconomic deprivation, and co-morbidities, warranting further attention by GPs and policymakers alike.
RESUMO
SORT IT (Structured Operational Research Training InitiaTive) is a successful capacity building programme started 10 years ago to develop operational research skills in low- and middle-income countries. Public Health England (PHE) aims to embed a culture of research in front-line staff, and SORT IT has been adapted to train frontline health protection professionals at PHE North West (PHE NW) to collate, analyse and interpret routinely collected data for evidence-informed decision-making. Six participants from the PHE NW Health Protection team were selected to attend a two-module course in Liverpool, UK, in May and in November 2018. Five participants finished the course with completed papers on characteristics and burden of influenza-like illness in elderly care homes (two papers), use of dried blood spots for blood-borne virus screening in prisons, uptake of meningococcal ACWY (groups A, C, W-135 and Y) vaccine in schoolchildren and fires in waste management sites. The SORT IT course led to 1) new evidence being produced to inform health protection practice, and 2) agreement within PHE NW to continue SORT IT with two courses per year, and 3) showed how a research capacity building initiative for low- and middle-income countries that combines 'learning with doing' can be adapted and used in a high-income country.
SORT IT (Structured Operational Research Training InitiaTive) est un programme fructueux de renforcement des capacités qui a démarré il y a 10 ans afin de développer des compétences en recherche opérationnelle dans les pays à revenu faible et moyen. Public Health England (PHE) vise à incorporer une culture de recherche au sein du personnel de première ligne. SORT IT a été adapté afin de former les professionnels de protection de la santé de première ligne à PHE-North West (PHE-NW) pour compiler, analyser et interpréter les données recueillies en routine en vue de prises de décisions basées sur des preuves. Six participants de l'équipe de PHE-NW Health Protection ont été choisis pour participer à un cours de deux modules à Liverpool, Royaume-Uni, en mai 2018 et en novembre 2018 respectivement. Cinq participants ont terminé le cours avec des articles achevés sur les caractéristiques et le fardeau des syndromes grippaux dans les maisons de retraite (deux articles), l'utilisation de gouttes de sang séché pour le dépistage des virus transmis par le sang dans les prisons, la couverture du vaccin anti-méningococcique ACWY (groupes A, C, W-135 and Y) chez les écoliers et les incendies dans les dépôts d'ordures. Les résultats et l'impact de cette approche incluent 1) la production de nouvelles preuves visant à informer les pratiques de protection de la santé ; 2) un accord au sein de PHE-NW pour poursuivre SORT IT avec deux cours par an ; et 3) la démonstration de la manière dont une initiative de renforcement des capacités de recherche destinée aux pays à revenu faible et moyen, qui combine « l'apprentissage par la pratique ¼, peut être adaptée et utilisée dans un pays à haut revenu.
El programa SORT IT (por Structured Operational Research Training InitiaTive) es una iniciativa eficaz de fortalecimiento de la capacidad, orientada a crear competencias en investigación operativa en los países de ingresos bajos y medianos, que se inició hace 10 años. La finalidad del organismo inglés de salud pública (PHE, por Public Health England) consiste en incorporar la cultura de la investigación en la práctica del personal de primera línea; el programa SORT IT se adaptó con miras a capacitar a los profesionales que prestan directamente la protección de la salud en el PHE-NW (noroccidente) para recopilar, analizar e interpretar los datos recogidos de manera sistemática y fundamentar así la adopción de decisiones basadas en la evidencia. Se escogieron seis participantes del equipo de protección de salud del PHE-NW para que asistieran a un curso en dos módulos en Liverpool, RU, en mayo del 2018 y noviembre del 2018. Cinco de los participantes terminaron el curso con la elaboración de artículos sobre las características y la carga de morbilidad por síndrome gripal en los hogares de ancianos (dos artículos), la utilización en las prisiones de muestras de manchas de sangre seca para el tamizaje de los virus de transmisión sanguínea, la aceptación de la vacuna ACWY (grupos A, C, W-135 and Y) contra el meningococo en los niños de edad escolar y los incendios en los centros de gestión de desechos. Los resultados y el impacto de esta iniciativa fueron los siguientes 1) se obtuvo nueva evidencia para fundamentar las prácticas de la protección de la salud; 2) se acordó continuar el programa SORT IT en el PHE-NW con dos cursos por año; y 3) se demostró cómo se puede adaptar una iniciativa de fortalecimiento de la capacidad en investigación dirigida a países de ingresos bajos y medianos, que asocia "aprender con hacer" para utilizarla en un país de ingresos altos.
RESUMO
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.

AIM: To examine the role of members of the NHS England Youth Forum (NHSEYF) and the strategies used to influence health service provision for children and young people. METHOD: An evaluative mixed-methods study was commissioned by NHS England and undertaken by the University of Hertfordshire between July 2015 and September 2016. Data collection comprised activity logs, a form of questionnaire, and semi-structured interviews. FINDINGS: The analysis of the activity logs revealed that the young people were undertaking a wide range of activities across England. Seven themes emerged from the interviews: the young people; motivation; commitment; community (the local area as well as a community spirit); knowledge experts; youth workers; and funding. In summary, the members of the NHSEYF were committed to their role and their work was having a positive effect on health service provision. CONCLUSION: The NHSEYF has developed rapidly and successfully. It is enabling the voice of young people to be heard.

Introduction The Public Health England (PHE; United Kingdom) Real-Time Syndromic Surveillance Team (ReSST) currently operates four national syndromic surveillance systems, including an emergency department system. A system based on ambulance data might provide an additional measure of the "severe" end of the clinical disease spectrum. This report describes the findings and lessons learned from the development and preliminary assessment of a pilot syndromic surveillance system using ambulance data from the West Midlands (WM) region in England. Hypothesis/Problem Is an Ambulance Data Syndromic Surveillance System (ADSSS) feasible and of utility in enhancing the existing suite of PHE syndromic surveillance systems? METHODS: An ADSSS was designed, implemented, and a pilot conducted from September 1, 2015 through March 1, 2016. Surveillance cases were defined as calls to the West Midlands Ambulance Service (WMAS) regarding patients who were assigned any of 11 specified chief presenting complaints (CPCs) during the pilot period. The WMAS collected anonymized data on cases and transferred the dataset daily to ReSST, which contained anonymized information on patients' demographics, partial postcode of patients' location, and CPC. The 11 CPCs covered a broad range of syndromes. The dataset was analyzed descriptively each week to determine trends and key epidemiological characteristics of patients, and an automated statistical algorithm was employed daily to detect higher than expected number of calls. A preliminary assessment was undertaken to assess the feasibility, utility (including quality of key indicators), and timeliness of the system for syndromic surveillance purposes. Lessons learned and challenges were identified and recorded during the design and implementation of the system. RESULTS: The pilot ADSSS collected 207,331 records of individual ambulance calls (daily mean=1,133; range=923-1,350). The ADSSS was found to be timely in detecting seasonal changes in patterns of respiratory infections and increases in case numbers during seasonal events. CONCLUSIONS: Further validation is necessary; however, the findings from the assessment of the pilot ADSSS suggest that selected, but not all, ambulance indicators appear to have some utility for syndromic surveillance purposes in England. There are certain challenges that need to be addressed when designing and implementing similar systems.

In April 2013, an H9N2 low pathogenicity avian influenza (LPAI) virus was isolated in a turkey breeder farm in Eastern England comprising 4966 birds. Point-of-lay turkey breeding birds had been moved from a rearing site and within 5 days had shown rapid onset of clinical signs of dullness, coughing, and anorexia. Three houses were involved, two contained a total of 4727 turkey hens, and the third housed 239 male turkeys. Around 50% of the hens were affected, whereas the male turkeys demonstrated milder clinical signs. Bird morbidity rose from 10% to 90%, with an increase in mortality in both houses of turkey hens to 17 dead birds in one house and 27 birds in the second house by day 6. The birds were treated with an antibiotic but were not responsive. Postmortem investigation revealed air sacculitis but no infraorbital sinus swellings or sinusitis. Standard samples were collected, and influenza A was detected. H9 virus infection was confirmed in all three houses by detection and subtyping of hemagglutinating agents in embryonated specific-pathogen-free fowls' eggs, which were shown to be viruses of H9N2 subtype using neuraminidase inhibition tests and a suite of real-time reverse transcription PCR assays. LPAI virus pathotype was suggested by cleavage site sequencing, and an intravenous pathogenicity index of 0.00 confirmed that the virus was of low pathogenicity. Therefore, no official disease control measures were required, and despite the high morbidity, birds recovered and were kept in production. Neuraminidase sequence analysis revealed a deletion of 78 nucleotides in the stalk region, suggesting an adaptation of the virus to poultry. Hemagglutinin gene sequences of two of the isolates clustered with a group of H9 viruses containing other contemporary European H9 strains in the Y439/Korean-like group. The closest matches to the two isolates were A/turkey/Netherlands/11015452/11 (H9N2; 97.9-98% nucleotide identity) and A/mallard/Finland/Li13384/10 (H9N2; 97% nucleotide identity). Both PB2 partial sequences were a 100% nucleotide identity with A/mallard/France/090360/09, indicating a European origin of the causative virus. Furthermore, partial sequencing analysis of the remaining genes revealed the virus to be genotypically of European avian origin and therefore of lower risk to public health compared with contemporary viruses in Central and Eastern Asia. Occupational health risks were assessed, and preventative measures were taken.

The seriousness and scale of the physical, psychological, economic and societal consequences relating to poor diets, inactivity and obesity is unprecedented. Consequently, the contextual factors underpinning the work of a nutritionist in the civil service are complex and significant; however, there are real opportunities to make a difference and help improve the health of the nation. The present paper describes the delivery of public health nutrition through two work programmes, namely action to support young people develop healthier lifestyle choices and more recently the investigation and deployment of local insights to develop action to tackle obesity. Combining the application of nutrition expertise along with broader skills and approaches has enabled the translation of research and evidence into programmes of work to better the public's health. It is evident that the appropriate evaluation of such approaches has helped to deliver engaging and practical learning opportunities for young people. Furthermore, efforts to build on local intelligence and seek collaborative development can help inform the evidence base and seek to deliver public health approaches, which resonate with how people live their lives.

Introduction In preparation for the London 2012 Olympic Games, existing syndromic surveillance systems operating in England were expanded to include daily general practitioner (GP) out-of-hours (OOH) contacts and emergency department (ED) attendances at sentinel sites (the GP OOH and ED syndromic surveillance systems: GPOOHS and EDSSS). Hypothesis/Problem The further development of syndromic surveillance systems in time for the London 2012 Olympic Games provided a unique opportunity to investigate the impact of a large mass-gathering event on public health and health services as monitored in near real-time by syndromic surveillance of GP OOH contacts and ED attendances. This can, in turn, aid the planning of future events. METHODS: The EDSSS and GPOOHS data for London and England from July 13 to August 26, 2012, and a similar period in 2013, were divided into three distinct time periods: pre-Olympic period (July 13-26, 2012); Olympic period (July 27 to August 12); and post-Olympic period (August 13-26, 2012). Time series of selected syndromic indicators in 2012 and 2013 were plotted, compared, and risk assessed by members of the Real-time Syndromic Surveillance Team (ReSST) in Public Health England (PHE). Student's t test was used to test any identified changes in pattern of attendance. RESULTS: Very few differences were found between years or between the weeks which preceded and followed the Olympics. One significant exception was noted: a statistically significant increase (P value = .0003) in attendances for "chemicals, poisons, and overdoses, including alcohol" and "acute alcohol intoxication" were observed in London EDs coinciding with the timing of the Olympic opening ceremony (9:00 pm July 27, 2012 to 01:00 am July 28, 2012). CONCLUSIONS: Syndromic surveillance was able to provide near to real-time monitoring and could identify hourly changes in patterns of presentation during the London 2012 Olympic Games. Reassurance can be provided to planners of future mass-gathering events that there was no discernible impact in overall attendances to sentinel EDs or GP OOH services in the host country. The increase in attendances for alcohol-related causes during the opening ceremony, however, may provide an opportunity for future public health interventions.

INTRODUCTION: Mandatory orthopaedic surgical site infection (SSI) data in England are used as a benchmark to compare infection rates between participating hospitals. According to the national guidelines, trusts are required to submit their data for at least one quarter of the year but they are free to report for all quarters. Owing to this ambiguity, there is a concern about robust reporting across trusts and therefore the accuracy of these data. There is also concern about the accuracy of collection methods. The aim of this five-year retrospective study was to assess the accuracy of SSI reporting at two hospitals in South East England under the same trust. METHODS: A retrospective review was carried out of five years of electronic medical records, microbiology data and readmission data of all patients who underwent hip and knee replacement surgery at these hospitals. These data were validated with the data submitted to Public Health England (PHE) and any discrepancy between the two was noted. RESULTS: A significant difference was found in the SSI rates reported by the surveillance staff and our retrospective method. CONCLUSIONS: Our study confirms the findings of a national survey, which raised concerns about the quality of SSI reporting and the usefulness of PHE SSI data for benchmarking purposes. To our knowledge, there are no previously published studies that have looked at the accuracy of the English orthopaedic SSI surveillance. In the light of our findings, there is an urgent need for external validation studies to identify the extent of the problem in the surveillance scheme. The governing bodies should also issue clear guidelines for reporting SSIs to maintain homogeneity and to present the true incidence of SSI. We suggest some measures that we have instituted to address these inadequacies that have led to significant improvements in reporting at our trust.

The Drug Interventions Programme is an initiative employed by the Home Office in 2003 to integrate the Criminal Justice System with drug treatment services with the ultimate goal of reducing acquisitive crime. Drug Action Teams employ this scheme on a local level by providing a broad range of services for misusers in the community. Although much attention has been placed on societal gains, there is an added benefit in improving the health outcomes of those referred. Opioid replacement therapy decreases illicit heroin use, reduces mortality and maintains contact with misusers allowing for psychosocial intervention. The Drug Interventions Programme provides direct access to such treatment in an otherwise high-risk and disengaged population. Anecdotal evidence of the programme is positive; with improved mental and physical health in offenders and a reduction in hospital admissions. However, monitoring health outcomes in offenders is challenging as long-term follow-up is difficult, poor compliance is an issue and coercive referrals may introduce a reporting bias. Drug Action Team services are cost-effective due a lower consumption of health and social care and reduced offending levels. The Drug Interventions Programme has been successful in maintaining offenders in treatment and the Home Office claim its role in reducing crime is cost-saving. Future delivery of the initiative is at risk due to spending reductions, competing interests and a focus towards payment by results. Opposition to future implementation of the Drug Interventions Programme must be met with evidence for its effectiveness in order to ensure its continued investment.

BACKGROUND: Reduction in the prevalence of vaccine type HPV infection in young women is an early indication of the impact of the HPV immunisation programme and a necessary outcome if the subsequent impact on cervical cancer is to be realised. METHODS: Residual vulva-vaginal swab (VVS) specimens from young women aged 16-24 years undergoing chlamydia screening in community sexual health services (formerly known as family planning clinics), general practice (GP), and youth clinics in 2010-2012 were submitted from 10 laboratories in seven regions around England. These specimens were linked to demographic and sexual behaviour data reported with the chlamydia test, anonymised, and tested for type-specific HPV DNA using a multiplex PCR and Luminex-based genotyping test. Estimated immunisation coverage was calculated and findings were compared to a baseline survey conducted prior to the introduction of HPV immunisation in 2008. RESULTS: A total of 4664 eligible specimens were collected and 4178 had a valid test result. The post-immunisation prevalence of HPV 16/18 infection was lowest in this youngest age group (16-18 years) and increased with age. This increase with age was a reversal of the pattern seen prior to immunisation and was inversely associated with estimates of age-specific immunisation coverage (65% for 16-18 year olds). The prevalence of HPV 16/18 infection in the post-immunisation survey was 6.5% amongst 16-18 year olds, compared to 19.1% in the similar survey conducted prior to the introduction of HPV immunisation. CONCLUSIONS: These findings are the first indication that the national HPV immunisation programme is successfully preventing HPV 16/18 infection in sexually active young women in England. The reductions seen suggest, for the estimated coverage, high vaccine effectiveness and some herd-protection benefits. Continued surveillance is needed to determine the effects of immunisation on non-vaccine HPV types.
