The first 5 years of Part 2A Orders: the use of powers from court applications to protect public health in England 2010-15.

BACKGROUND: Part 2A Orders are the legal means which allow local authorities (LAs), upon application to court, to exercise powers over persons, things or premises to protect public health. METHODS: We surveyed lead professionals involved in applications to understand the use and utility of such Orders since their inception in April 2010 to July 2015. RESULTS: All applications for Orders were granted; 29 for persons (28 for tuberculosis, 1 for HIV); these were renewed in 18 (18/25, 72%) cases up to seven times; 23 applications related to things (tattoo and piercing equipment); and three applications related to 'premises' (Escherichia coli 0137 on farm, faecal contamination). Use of the Orders against things occurred where there was failure of the Health and Safety Executive to transfer powers to LAs. Orders against persons were used as a last resort and renewed until treatment completion in the minority of cases (n = 3). One patient was detained under quarantine powers while assessing infectiousness. Significant difficulties in implementing the Part 2A Orders due to lack of resources, facilities and interagency collaboration were reported. CONCLUSIONS: Part 2A Orders are used as a last resort but improved facilities for safe and secure isolation would help improve implementation.

Outcomes analysis of new entrant screening for active tuberculosis in Heathrow and Gatwick airports, United Kingdom 2009/2010.

BACKGROUND: In 2012, the United Kingdom (UK) Government announced that the new entrant screening for active tuberculosis (TB) in Heathrow and Gatwick airports would end. Our study objective was to estimate screening yield and diagnostic accuracy, and identify those at risk of active TB after entry. METHODS: We designed a retrospective cohort study and linked new entrants screened from June 2009 to September 2010 through probabilistic matching with UK Enhanced TB Surveillance (ETS) data (June 2009 to December 2010). Yield was the proportion of cases reported to ETS within three months of airport screening in the screened population. To estimate screening diagnostic accuracy we assessed sensitivity, specificity, positive and negative predictive values. Through Poisson regression we identified groups at increased risk of TB diagnosis after entry. RESULTS: We identified 200,199 screened entrants, of these 59 had suspected TB at screening and were reported within 3 months to ETS (yield = 0.03 %). Sensitivity was 26 %; specificity was 99.7 %; positive predictive value was 13.2 %; negative predictive value was 99.9 %. Overall, 350 entrants were reported in ETS. Persons from countries with annual TB incidence higher than 150 cases per 100,000 population and refugees and asylum seekers were at increased risk of TB diagnosis after entry (population attributable risk 77 and 3 % respectively). CONCLUSION: Airport screening has very low screening yields, sensitivity and positive predictive value. New entrants coming from countries with annual TB incidence higher than 150 per 100,000 population, refugees and asylum seekers should be prioritised at pre- or post-entry screening.

Mortality during the 2013 heatwave in England--How did it compare to previous heatwaves? A retrospective observational study.

Heatwaves are predicted to increase in frequency and intensity as a result of climate change. The health impacts of these events can be significant, particularly for vulnerable populations when mortality can occur. England experienced a prolonged heatwave in summer 2013. Daily age-group and region-specific all-cause excess mortality during summer 2013 and previous heatwave periods back to 2003 was determined using the same linear regression model and heatwave definition to estimate impact and place observations from 2013 in context. Predicted excess mortality due to heat during this period was also independently estimated. Despite a sustained heatwave in England in 2013, the impact on mortality was considerably less than expected; a small cumulative excess of 195 deaths (95% confidence interval -87 to 477) in 65+ year olds and 106 deaths (95% CI -22 to 234) in <65 year olds was seen, nearly a fifth of excess deaths predicted based on observed temperatures. This impact was also less than seen in 2006 (2323 deaths) and 2003 (2234 deaths), despite a similarly prolonged period of high temperatures. The reasons for this are unclear and further work needs to be done to understand this and further clarify the predicted impact of increases in temperature.

Using real-time syndromic surveillance to assess the health impact of the 2013 heatwave in England.

Heatwaves are a seasonal threat to public health. During July 2013 England experienced a heatwave; we used a suite of syndromic surveillance systems to monitor the impact of the heatwave. Significant increases in heatstroke and sunstroke were observed during 7-10 July 2013. Syndromic surveillance provided an innovative and effective service, supporting heatwave planning and providing early warning of the impact of extreme heat thereby improving the public health response to heatwaves.

Poor uptake of primary healthcare registration among recent entrants to the UK: a retrospective cohort study.

OBJECTIVES: Uptake of healthcare among migrants is a complex and controversial topic; there are multiple recognised barriers to accessing primary care. Delays in presentation to healthcare services may result in a greater burden on costly emergency care, as well as increased public health risks. This study aimed to explore some of the factors influencing registration of new entrants with general practitioners (GPs). DESIGN: Retrospective cohort study. SETTING: Port health screening at Heathrow and Gatwick airports, primary care. PARTICIPANTS: 252 559 new entrants to the UK, whose entry was documented by the port health tuberculosis screening processes at Heathrow and Gatwick. 191 had insufficient information for record linkage. PRIMARY OUTCOME MEASURE: Registration with a GP practice within the UK, as measured through record linkage with the Personal Demographics Service (PDS) database. RESULTS: Only 32.5% of 252 368 individuals were linked to the PDS, suggesting low levels of registration in the study population. Women were more likely to register than men, with a RR ratio of 1.44 (95% CI 1.41 to 1.46). Compared with those from Europe, individuals of nationalities from the Americas (0.43 (0.39 to 0.47)) and Africa (0.74 (0.69 to 0.79)) were less likely to register. Similarly, students (0.83 (0.81 to 0.85)), long-stay visitors (0.82 (0.77 to 0.87)) and asylum seekers (0.46 (0.42 to 0.51)) were less likely to register with a GP than other migrant groups. CONCLUSIONS: Levels of registration with GPs within this selected group of new entrants, as measured through record linkage, are low. Migrant groups with the lowest proportion registered are likely to be those with the highest health needs. The UK would benefit from a targeted approach to identify the migrants least likely to register for healthcare and to promote access among both users and service providers.

Rapid estimation of excess mortality: nowcasting during the heatwave alert in England and Wales in June 2011.

BACKGROUND: A Heat-Health Watch system has been established in England and Wales since 2004 as part of the national heatwave plan following the 2003 European-wide heatwave. One important element of this plan has been the development of a timely mortality surveillance system. This article reports the findings and timeliness of a daily mortality model used to 'nowcast' excess mortality (utilising incomplete surveillance data to estimate the number of deaths in near-real time) during a heatwave alert issued by the Met Office for regions in South and East England on 24 June 2011. METHODS: Daily death registrations were corrected for reporting delays with historical data supplied by the General Registry Office. These corrected counts were compared with expected counts from an age-specific linear regression model to ascertain if any excess had occurred during the heatwave. RESULTS: Excess mortality of 367 deaths was detected across England and Wales in ≥85-year-olds on 26 and 27 June 2011, coinciding with the period of elevated temperature. This excess was localised to the east of England and London. It was detected 3 days after the heatwave. CONCLUSION: A daily mortality model was sensitive and timely enough to rapidly detect a small excess, both, at national and regional levels. This tool will be useful when future events of public health significance occur.

Seroepidemiologic study of pandemic (H1N1) 2009 during outbreak in boarding school, England.

We conducted a seroepidemiologic study during an outbreak of pandemic (H1N1) 2009 in a boarding school in England. Overall, 353 (17%) of students and staff completed a questionnaire and provided a serum sample. The attack rate was 40.5% and 34.1% for self-reported acute respiratory infection (ARI). Staff were less likely to be seropositive than students 13-15 years of age (staff 20-49 years, adjusted odds ratio [AOR] 0.30; >50 years AOR 0.20). Teachers were more likely to be seropositive than other staff (AOR 7.47, 95% confidence interval [CI] 2.31-24.2). Of seropositive persons, 44.6% (95% CI 36.2%-53.3%) did not report ARI. Conversely, of 141 with ARI and 63 with influenza-like illness, 45.8% (95% CI 37.0%-54.0%) and 30.2% (95% CI 19.2%-43.0%) had negative test results, respectively. A weak association was found between seropositivity and a prophylactic dose of antiviral agents (AOR 0.55, 95% CI 0.30-0.99); prophylactic antiviral agents lowered the odds of ARI by 50%.

Планы действий по защите здоровья населения от воздействия аномальной жары: руководство

В результате климатических изменений меняются погодные условия и по-видимому возрастает частота экстремальных погодных явлений, включая волны жары. В Европейском регионе ВОЗ ряд таких волн, имевших место в последнее время, стал причиной дополнительных случаев смерти, несмотря на то, что неблагоприятное влияние жаркой погоды и волн жары на здоровье людей в основном может быть предотвращено. Для эффективной профилактики заболеваемости и смертности, связанных с жарой, необходим комплекс действий на различных уровнях, включая создание и поддержание метеорологических систем раннего предупреждения, своевременное распространение рекомендаций о мерах профилактики и защиты, совершенствование жилищного и городского строительства, а также принятие мер, обеспечивающих готовность системы здравоохранения и системы социальной защиты к принятию необходимых мер. Все эти действия могут быть интегрированы в специальном плане защиты населения в периоды жары. Данное руководство является результатом работы в рамках проекта EuroHEAT, посвященного улучшению действий общественного здравоохранения во время экстремальных погодных явлений/волн жары, который финансируется совместно ВОЗ и Европейской комиссией. В руководстве объясняется важность создания планов защиты населения в периоды жары, указываются их основные характеристики и элементы, а также приводятся примеры из нескольких европейских стран, приступивших к реализации и оценке таких планов.

The implementation of chlamydia screening: a cross-sectional study in the south east of England.

BACKGROUND: England's National Chlamydia Screening Programme (NCSP) provides opportunistic testing for under 25 year-olds in healthcare and non-healthcare settings. The authors aimed to explore relationships between coverage and positivity in relation to demographic characteristics or setting, in order to inform efficient and sustainable implementation of the NCSP. METHODS: The authors analysed mapped NCSP testing data from the South East region of England between April 2006 and March 2007 inclusive to population characteristics. Coverage was estimated by sex, demographic characteristics and service characteristics, and variation in positivity by setting and population group. RESULTS: Coverage in females was lower in the least deprived areas compared with the most deprived areas (OR 0.48; 95% CI 0.45 to 0.50). Testing rates were lower in 20-24-year-olds compared with 15-19-year-olds (OR 0.69; 95% CI 0.67 to 0.72 for females and OR 0.67; 95% CI 0.64 to 0.71 for males), but positivity was higher in older males. Females were tested most often in healthcare services, which also identified the most positives. The greatest proportions of male tests were in university (27%) and military (19%) settings which only identified a total of 11% and 13% of total male positives respectively. More chlamydia-positive males were identified through healthcare services despite fewer numbers of tests. CONCLUSIONS: Testing of males focused on institutional settings where there is a low yield of positives, and limited capacity for expansion. By contrast, the testing of females, especially in urban environments, was mainly through established healthcare services. Future strategies should prioritise increasing male testing in healthcare settings.

Heat–health action plans: guidance

Climate change is leading to variations in weather patterns and an apparent increase in extreme weather events, including heat-waves. Recent heat-waves in the WHO European Region have led to a rise in related mortality, but the adverse health effects of hot weather and heat-waves are largely preventable. Prevention requires a portfolio of actions at different levels, including meteorological early warning systems, timely public and medical advice, improvements to housing and urban planning, and ensuring that health care and social systems are ready to act. These actions can be integrated into a defined heat–health action plan. This guidance results from the EuroHEAT project on improving public health responses to extreme weather/heat-waves, co-funded by WHO and the European Commission. It explains the importance of the development of heat–health action plans, their characteristics and core elements, with examples from several European countries that have begun their implementation and evaluation.

Public health professionals' perceptions toward provision of health protection in England: a survey of expectations of Primary Care Trusts and Health Protection Units in the delivery of health protection.

BACKGROUND: Effective health protection requires systematised responses with clear accountabilities. In England, Primary Care Trusts and the Health Protection Agency both have statutory responsibilities for health protection. A Memorandum of Understanding identifies responsibilities of both parties, but there is a potential lack of clarity about responsibility for specific health protection functions. We aimed to investigate professionals' perceptions of responsibility for different health protection functions, to inform future guidance for, and organisation of, health protection in England. METHODS: We sent a postal questionnaire to all health protection professionals in England from the following groups: (a) Directors of Public Health in Primary Care Trusts; (b) Directors of Health Protection Units within the Health Protection Agency; (c) Directors of Public Health in Strategic Health Authorities and; (d) Regional Directors of the Health Protection Agency RESULTS: The response rate exceeded 70%. Variations in perceptions of who should be, and who is, delivering health protection functions were observed within, and between, the professional groups (a)-(d). Concordance in views of which organisation should, and which does deliver was high (> or =90%) for 6 of 18 health protection functions, but much lower (< or =80%) for 6 other functions, including managing the implications of a case of meningitis out of hours, of landfill environmental contamination, vaccination in response to mumps outbreaks, nursing home infection control, monitoring sexually transmitted infections and immunisation training for primary care staff. The proportion of respondents reporting that they felt confident most or all of the time in the safe delivery of a health protection function was strongly correlated with the concordance (r = 0.65, P = 0.0038). CONCLUSION: Whilst we studied professionals' perceptions, rather than actual responses to incidents, our study suggests that there are important areas of health protection where consistent understanding of responsibility for delivery is lacking. There are opportunities to clarify the responsibility for health protection in England, perhaps learning from the approaches used for those health protection functions where we found consistent perceptions of accountability.
