Objective: To compare pregnancy rates and outcomes for women with cystic fibrosis in the UK with those of the general population and assess the effect of the introduction of disease‐modifying treatment. Design: A population‐based longitudinal study, 2003–17. Setting: United Kingdom. Population: Women aged 15–44 years in the UK cystic fibrosis (CF) Registry compared with women in England and Wales. Methods: We calculated pregnancy and live‐birth rates for the CF population and the general population of England and Wales. For women with CF we compared pregnancy rates before and after ivacaftor was introduced in 2013. We further used CF registry data to assess pregnancy outcomes for mothers with CF, and to assess the relationship between maternal pre‐pregnancy lung function and nutritional status and child gestational age. Main outcome measures: Pregnancy and live‐birth rates and child gestational age. Results: Of 3831 women with CF, 661 reported 818 pregnancies. Compared with the general population, the pregnancy rate was 3.3 times lower in the CF population (23.5 versus 77.7 per 1000 woman‐years); the live‐birth rate was 3.5 times lower (17.4 versus 61.4 per 1000 woman‐years) with 70% of pregnancies in CF women resulting in live births; termination of pregnancy rates were also lower (9% versus 22%). Pregnancy rates increased post‐ivacaftor for eligible women with CF, from 29.7 to 45.7 per 1000 woman‐years. There was no association between pre‐pregnancy lung function/nutrition status and gestational age. Conclusions: Pregnancy rates in women with CF are about one‐third of the rates in the general population with favourable outcomes, and increased for eligible women post‐ivacaftor. Pregnancy rates in women with CF are about a third of the rate in England and Wales with 70% live births. Ivacaftor increases the rate. [ABSTRACT FROM AUTHOR]

Nursing care is a major factor in the cost of most medical treatments. This paper reports on two alternative techniques for estimating the costs of nursing care, in the context of colorectal cancer treatment on a surgical ward in the University Hospital, Nottingham. The simpler, but cruder, technique is based on average patient costs, whilst the other is patient-specific and incorporates the use of nursing dependency data. Results from the two estimation methods are compared and the implications for the proper costing of nursing care are discussed. [ABSTRACT FROM AUTHOR]

Background: Chronic subdural haematoma (cSDH) is a common neurosurgical pathology affecting older patients with other health conditions. A significant proportion (up-to 90%) of referrals for surgery in neurosciences units (NSU) come from secondary care. However, the organisation of this care and the experience of patients repatriated to non-specialist centres are currently unclear., Objectives: This study aimed to clarify patient outcome in non-specialist centres following NSU discharge for cSDH surgery and to understand key system challenges. The study was set within a representative neurosurgical care system in the east of England., Design and Methods: We performed a retrospective cohort analysis of patients referred for cSDH surgery. Alongside case record review, patient and staff experience were explored using surveys as well as an interactive c-design workshop. Challenges were identified from thematic analysis of survey responses and triangulated by focussed workshop discussions., Results: Data on 381 patients referred for cSDH surgery from six centres was reviewed. One hundred and fifty-six (41%) patients were repatriated following surgery. Sixty-one (39%) of those repatriated suffered an inpatient complication (new infection, troponin rise or renal injury) following NSU discharge, with 58 requiring institutional discharge or new care. Surveys for staff (n = 42) and patients (n = 209) identified that resourcing, communication, and inter-hospital distance posed care challenges. This was corroborated through workshop discussions with stakeholders from two institutions., Conclusions: A significant amount of perioperative care for cSDH is delivered outside of specialist centres. Future improvement initiatives must recognise the system-wide nature of delivery and the challenges such an arrangement presents., (© The Author(s) 2024.

The origins of today's surgical societies are the guilds of medieval London. The Company of Barbers and the Guild of Surgeons vied for dominance no different from the scores of conflicts between rival artisans and merchants whose trades overlapped. The Company dates from 1308, when the council of London passed ordinances that installed its first master, Richard le Barber. When the surgeons received ordinances of their own in 1368, the barbers had the Council reassert theirs in 1376, 1390, 1415, and 1424. Faced with a vigorous organization with greater numbers the surgeons aligned with the physicians in 1423 to form a short-lived ruling "commonalty" with an elite membership based on educational achievement and proven ability that excluded the barbers. The surgeons were thereby granted authority over all of surgery, including that practiced by barbers, an arrangement that failed after only a year. The surgeons formed a guild in 1435 but could not compete with the barbers. The barbers' primacy became complete in 1462 when Edward IV chartered them to govern all aspects of surgery, along with the power to fine and imprison. From then barbers and surgeons amiably coexisted, likely because the rapidly growing population and the democratization of the practice of physic provided plenty of work. Henry VIII formally united the barbers and surgeons in 1540 under the Worshipful Company of Barbers and Surgeons, an amalgamation that lasted for two centuries until the surgeons broke away in 1745., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: The measurement of dementia in cross-national contexts relies on the assessment of functional limitations. We aimed to evaluate the performance of survey items on functional limitations across culturally diverse geographic settings., Methods: We used data from the Harmonized Cognitive Assessment Protocol Surveys (HCAP) in five countries (total N = 11,250) to quantify associations between items on functional limitations and cognitive impairment., Results: Many items performed better in the United States and England compared to South Africa, India, and Mexico. Items on the Community Screening Instrument for Dementia (CSID) had the least variability across countries (SD = 0.73 vs. 0.92 [Blessed] and 0.98 [Jorm IQCODE]), but also the weakest associations with cognitive impairment (median odds ratio [OR] = 2.23 vs. 3.01 [Blessed] and 2.75 [Jorm IQCODE])., Discussion: Differences in cultural norms for reporting functional limitations likely influences performance of items on functional limitations and may affect the interpretation of results from substantive studies., Highlights: There was substantial cross-country variation in item performance. Items from the Community Screening Instrument for Dementia (CSID) had less cross-country variability but lower performance. There was more variability in performance of instrumental activities of daily living (IADL) compared to activities of daily living (ADL) items. Variability in cultural expectations of older adults should be taken into account. Results highlight the need for novel approaches to assessing functional limitations., (© 2023 The Authors.

Introduction: Most cognitive assessments have been developed in high-income countries but are used in diverse contexts. Differences in culture and context may affect the performance of cognitive items., Methods: We used the Harmonized Cognitive Assessment Protocol (HCAP) surveys in the United States, Mexico, India, England, and South Africa (combined N = 11,364) to quantify associations across countries between cognitive items and cognitive impairment status using age- and sex-adjusted logistic regression., Results: Associations were stronger in the United States (median odds ratio [OR] across items = 0.17) and England (median OR = 0.19), compared to South Africa (median OR = 0.23), India (median OR = 0.29), and Mexico (median OR = 0.28). Items assessing memory (e.g., delayed recall tasks) had the most consistent associations of the largest magnitudes across contexts., Discussion: Transporting cognitive items among countries and cultures warrants caution. Our results can guide the design of future instruments by identifying items that performed well either in individual contexts or across the range of contexts considered., Highlights: Little quantitative evidence exists to guide the design of cognitive assessments in cross-national studies. The performance of cognitive items for the measurement of dementia varied across countries. Items with lower variation across countries (e.g., delayed word recall) should be used in future cross-national assessments. Across countries, there was variability in the performance of language assessments, with the exception of the animal naming task. Results can be used to design future cross-national or location-specific cognitive assessments., (© 2022 the Alzheimer's Association.)

Never a monarch nor head of state, Queen Caroline of Ansbach (1683-1737) is among the legendary women rulers of England and Great Britain alongside Queens Elizabeth I and II, Queen Victoria, and Lady Margaret Thatcher. As queen consort, she was the acknowledged power behind the throne of her husband, King George II (1683-1760), working with Robert Walpole, the first Prime Minister of England. George accepted her intellectual superiority and backstage dominance even before he acceded to the throne in 1727. "[He had] no pretensions toward intellect and [was] basically interested in little more than military glory, political power, and a wife who would do her duty by providing him with male heirs," wrote popular historian John Van de Kiste. After they were wed in 1705, Caroline carried out her task with a remarkable fecundity: a male heir, Frederick Louis, in 1707, followed by Anne (1709), Amelia (1711), Caroline (1713), George William (1717), William (1721), Mary (1723), and Louise (1724). With good reason she believed that her influence over George came from his sexual attraction to her. It was a conceit that proved to be her undoing as she strove to hide from common knowledge an unsightly umbilical hernia. The rupture caused her death in 1737 at age 54. It strangulated, perforated, and spilled feculent succus entericus and fetid fluid onto the royal bed, a vivid example of the consequences of an untreated surgical condition.

Background: Children in care face adverse health outcomes throughout their life course compared with their peers. In England, over the past decade, the stark rise in the number of cared-for children has coincided with rising child poverty, a key risk factor for children entering care. We aimed to assess the contribution of recent trends in child poverty to trends in care entry., Methods: In this longitudinal, ecological study of 147 local authorities in England, we linked data from the Department for Work and Pensions and HM Revenue & Customs on the proportion of children younger than 16 years living in families with income less than 60% of the contemporary national median income, before housing costs, with Department for Education data on rates of children younger than 16 years entering care. Using within-between regression models, and controlling for employment trends, we estimated the association of changing child poverty rates with changing care entry rates within different areas. Our primary outcome was the annual rate of children younger than 16 years starting to be looked after by local authorities in England., Findings: Between 2015 and 2020, controlling for employment rates, a 1 percentage point increase in child poverty was associated with an additional five children entering care per 100 000 children (95% CI 2-8). We estimate that, over the study period, 8·1% of the total number of children under the age of 16 entering care (5·0-11·3) were linked to rising child poverty, equivalent to 10 351 (6447-14 567) additional children., Interpretation: We report evidence that rising child poverty rates might be contributing to an increase in children entering care. Children's exposure to poverty creates and compounds adversity, driving poor health and social outcomes in later life. National anti-poverty policies are key to tackling adverse trends in children's care entry in England., Funding: National Institute for Health Research (NIHR) School for Public Health Research, NIHR Public Health Policy Research Unit, Swedish Research Council, Wellcome Trust, Medical Research Council, and NIHR Applied Research Collaboration North West Coast., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2022 The Author(s).

Background: We aimed to investigate the impact of socio-economic inequalities in cancer survival in England on the Number of Life-Years Lost (NLYL) due to cancer., Methods: We analysed 1.2 million patients diagnosed with one of the 23 most common cancers (92.3% of all incident cancers in England) between 2010 and 2014. Socio-economic deprivation of patients was based on the income domain of the English Index of Deprivation. We estimated the NLYL due to cancer within 3 years since diagnosis for each cancer and stratified by sex, age and deprivation, using a non-parametric approach. The relative survival framework enables us to disentangle death from cancer and death from other causes without the information on the cause of death., Results: The largest socio-economic inequalities were seen mostly in adults <45 years with poor-prognosis cancers. In this age group, the most deprived patients with lung, pancreatic and oesophageal cancer lost up to 6 additional months within 3 years since diagnosis than the least deprived. For most moderate/good prognosis cancers, the socio-economic inequalities widened with age., Conclusions: More deprived patients and particularly the young with more lethal cancers, lose systematically more life-years than the less deprived. To reduce these inequalities, cancer policies should systematically encompass the inequities component., (© 2022. The Author(s).)

The evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus leads to new variants that warrant timely epidemiological characterization. Here we use the dense genomic surveillance data generated by the COVID-19 Genomics UK Consortium to reconstruct the dynamics of 71 different lineages in each of 315 English local authorities between September 2020 and June 2021. This analysis reveals a series of subepidemics that peaked in early autumn 2020, followed by a jump in transmissibility of the B.1.1.7/Alpha lineage. The Alpha variant grew when other lineages declined during the second national lockdown and regionally tiered restrictions between November and December 2020. A third more stringent national lockdown suppressed the Alpha variant and eliminated nearly all other lineages in early 2021. Yet a series of variants (most of which contained the spike E484K mutation) defied these trends and persisted at moderately increasing proportions. However, by accounting for sustained introductions, we found that the transmissibility of these variants is unlikely to have exceeded the transmissibility of the Alpha variant. Finally, B.1.617.2/Delta was repeatedly introduced in England and grew rapidly in early summer 2021, constituting approximately 98% of sampled SARS-CoV-2 genomes on 26 June 2021., (© 2021.

Background: Targeted obesity prevention policies would benefit from the identification of population groups with the highest risk of weight gain. The relative importance of adult age, sex, ethnicity, geographical region, and degree of social deprivation on weight gain is not known. We aimed to identify high-risk groups for changes in weight and BMI using electronic health records (EHR)., Methods: In this longitudinal, population-based cohort study we used linked EHR data from 400 primary care practices (via the Clinical Practice Research Datalink) in England, accessed via the CALIBER programme. Eligible participants were aged 18-74 years, were registered at a general practice clinic, and had BMI and weight measurements recorded between Jan 1, 1998, and June 30, 2016, during the period when they had eligible linked data with at least 1 year of follow-up time. We calculated longitudinal changes in BMI over 1, 5, and 10 years, and investigated the absolute risk and odds ratios (ORs) of transitioning between BMI categories (underweight, normal weight, overweight, obesity class 1 and 2, and severe obesity [class 3]), as defined by WHO. The associations of demographic factors with BMI transitions were estimated by use of logistic regression analysis, adjusting for baseline BMI, family history of cardiovascular disease, use of diuretics, and prevalent chronic conditions., Findings: We included 2 092 260 eligible individuals with more than 9 million BMI measurements in our study. Young adult age was the strongest risk factor for weight gain at 1, 5, and 10 years of follow-up. Compared with the oldest age group (65-74 years), adults in the youngest age group (18-24 years) had the highest OR (4·22 [95% CI 3·86-4·62]) and greatest absolute risk (37% vs 24%) of transitioning from normal weight to overweight or obesity at 10 years. Likewise, adults in the youngest age group with overweight or obesity at baseline were also at highest risk to transition to a higher BMI category; OR 4·60 (4·06-5·22) and absolute risk (42% vs 18%) of transitioning from overweight to class 1 and 2 obesity, and OR 5·87 (5·23-6·59) and absolute risk (22% vs 5%) of transitioning from class 1 and 2 obesity to class 3 obesity. Other demographic factors were consistently less strongly associated with these transitions; for example, the OR of transitioning from normal weight to overweight or obesity in people living in the most socially deprived versus least deprived areas was 1·23 (1·18-1·27), for men versus women was 1·12 (1·08-1·16), and for Black individuals versus White individuals was 1·13 (1·04-1·24). We provide an open access online risk calculator, and present high-resolution obesity risk charts over a 1-year, 5-year, and 10-year follow-up period., Interpretation: A radical shift in policy is required to focus on individuals at the highest risk of weight gain (ie, young adults aged 18-24 years) for individual-level and population-level prevention of obesity and its long-term consequences for health and health care., Funding: The British Hearth Foundation, Health Data Research UK, the UK Medical Research Council, and the National Institute for Health Research., Competing Interests: Declaration of interests RLB reports consulting fees from Novo Nordisk, ViiV Healthcare, Pfizer, and Gila Therapeutics; payment or honoraria for lectures, presentations, speakers bureaus, manuscript writing or educational events from Novo Nordisk, ViiV Healthcare, International Medical Press, and Medscape; participation on a data safety monitoring board or advisory board for Novo Nordisk, Pfizer, and ViiV Healthcare; being a committee member of the British Obesity and Metabolic Surgery Society, a trustee for the Association for the Study of Obesity, a scientific chair of the International Federation for the Surgery for Obesity (IFSO) and metabolic disorders European Chapter, a chair of the Royal College of Physicians advisory Committee on Nutrition, Weight and Health, an European Society of Endocrinology clinical committee member, and a trustee of Obesity Empowerment Network UK; being a member of the IFSO scientific committee; being a member of the NICE Weight Management Guideline Development Group; and being a principal investigator on two obesity clinical trials of cagrilintide versus placebo and semaglutide versus placebo (sponsored by Novo Nordisk), and one clinical trial of liraglutide versus placebo (both drugs were provided by Novo Nordisk).

Introduction: Vaccination against the COVID-19 virus began in December 2020 in the UK and into Spring 2021 has been running at 5% population/week. High levels of social restrictions were implemented for the third time in January 2021 to control the second wave and resulting increases in hospitalisations and deaths. Easing those restrictions must balance multiple challenging priorities, weighing the risk of more deaths and hospitalisations against damage done to mental health, incomes and standards of living, education and provision of non-Covid-19 healthcare., Methods: Weekly and monthly officially published data for 2020/21 were used to estimate the influence of seasonality and social restrictions on the spread of COVID-19 by age group, on the economy and on healthcare services. These factors were combined with the estimated impact of vaccinations and immunity from past infections into a model that retrospectively reflected the actual numbers of reported deaths closely both in 2020 and early 2021. The model was applied prospectively to the next 6 months to evaluate the impact of different speeds of easing social restrictions., Results: The results show vaccinations as significantly reducing the number of hospitalisations and deaths. The central estimate is that relative to rapid easing, the avoided loss of 57 000 life-years from a strategy of relatively slow easing over the next several  months comes at a cost in terms of GDP reduction of around £0.4 million/life-year loss avoided. This is over 10 times higher than the usual limit the NHS uses for spending against Quality Adjusted Life Years (QALYs) saved. Alternative assumptions for key factors affecting the spread of the virus give significantly different trade-offs between costs and benefits of different speeds of easing. Disruption of non-Covid-19 Healthcare provision also increases in times of higher levels of social restrictions., Conclusion: In most cases, the results favour a somewhat faster easing of restrictions in England than current policy implies., (© 2021 The Authors.

The SARS-CoV-2 lineage B.1.1.7, designated variant of concern (VOC) 202012/01 by Public Health England 1 , was first identified in the UK in late summer to early autumn 2020 2 . Whole-genome SARS-CoV-2 sequence data collected from community-based diagnostic testing for COVID-19 show an extremely rapid expansion of the B.1.1.7 lineage during autumn 2020, suggesting that it has a selective advantage. Here we show that changes in VOC frequency inferred from genetic data correspond closely to changes inferred by S gene target failures (SGTF) in community-based diagnostic PCR testing. Analysis of trends in SGTF and non-SGTF case numbers in local areas across England shows that B.1.1.7 has higher transmissibility than non-VOC lineages, even if it has a different latent period or generation time. The SGTF data indicate a transient shift in the age composition of reported cases, with cases of B.1.1.7 including a larger share of under 20-year-olds than non-VOC cases. We estimated time-varying reproduction numbers for B.1.1.7 and co-circulating lineages using SGTF and genomic data. The best-supported models did not indicate a substantial difference in VOC transmissibility among different age groups, but all analyses agreed that B.1.1.7 has a substantial transmission advantage over other lineages, with a 50% to 100% higher reproduction number.

Background and Objectives: The Best Pharmaceuticals for Children Act (BPCA) incentivizes the study of on-patent medicines in children and mandates that the National Institutes of Health sponsor research on off-patent drugs important to pediatric therapeutics. Failing to enroll cohorts that reflect the pediatric population at large restricts the generalizability of such studies. In this investigation, we evaluate racial and ethnic minority representation among participants enrolled in BPCA-sponsored studies., Methods: Data were obtained for all participants enrolled in 33 federally funded studies of drugs and devices conducted from 2008 through June 2020. Observed racial and ethnic distributions were compared with expected distributions by sampling Census data at the same geographic frequency as in the studies. Racial and ethnic enrollment was examined by demography, geography, study type, study burden, and expected bias. Standard descriptive statistics, χ 2 , generalized linear models, and linear regression were applied., Results: A total of 10 918 participants (51% male, 6.6 ± 8.2 years) were enrolled across 46 US states and 4 countries. Studies ranged from treatment outcome reviews to randomized, placebo-controlled trials. Minority enrollment was comparable to, or higher than, expected (+0.1% to +2.6%) for all groups except Asian Americans (-3.7%, P < .001). American Indian and Alaskan Native and multiracial enrollment significantly increased over the evaluation period ( P < .01). There were no significant differences in racial distribution as a function of age or sex, although differences were observed on the basis of geography, study type, and study burden., Conclusions and Relevance: This study revealed no evidence of racial and ethnic bias in enrollment for pediatric studies conducted with funding from BPCA, fulfilling the legislation's expectation to ensure adequate representation of all children., Competing Interests: POTENTIAL CONFLICT OF INTEREST: Dr Abdel-Rahman, Ms Delmore, and Drs Hornik, Paul, Sullivan, Wade, and Zimmerman serve as members of the steering committee for the Pediatric Trials Network, which receives Best Pharmaceuticals for Children Act funding from the Eunice Kennedy Shriver National Institute for Child Health and Human Development.

COVID-19 poses a major challenge to care homes, as SARS-CoV-2 is readily transmitted and causes disproportionately severe disease in older people. Here, 1167 residents from 337 care homes were identified from a dataset of 6600 COVID-19 cases from the East of England. Older age and being a care home resident were associated with increased mortality. SARS-CoV-2 genomes were available for 700 residents from 292 care homes. By integrating genomic and temporal data, 409 viral clusters within the 292 homes were identified, indicating two different patterns - outbreaks among care home residents and independent introductions with limited onward transmission. Approximately 70% of residents in the genomic analysis were admitted to hospital during the study, providing extensive opportunities for transmission between care homes and hospitals. Limiting viral transmission within care homes should be a key target for infection control to reduce COVID-19 mortality in this population., Competing Interests: WH, GT, ES, DA, CH, BW, LM, MH, AJ, MC, SP, LC, SC, FK, AY, GH, TF, MP, IG, YC, CB, SG, RA, EH, NB, MB, MS, DJ, IJ, AA, JS, CL, GD, SP, DK, IG No competing interests declared, MT I have received grant support from the Academy of Medical Sciences, the Health Foundation, and the NIHR Biomedical Research Centre.

Objective: To assess trends in inequalities in Children Looked After (CLA) in England between 2004 and 2019, after controlling for unemployment, a marker of recession and risk factor for child maltreatment., Design: Longitudinal local area ecological analysis., Setting: 150 English upper-tier local authorities., Participants: Children under the age of 18 years., Primary Outcome Measure: The annual age-standardised rate of children starting to be looked after (CLA rate) across English local authorities, grouped into quintiles based on their level of income deprivation. Slope indices of inequality were estimated using longitudinal segmented mixed-effects models, controlling for unemployment., Results: Since 2008, there has been a precipitous rise in CLA rates and a marked widening of inequalities. Unemployment was associated with rising CLA rates: for each percentage point increase in unemployment rate, an estimated additional 9 children per 100 000 per year (95% CI 6 to 11) became looked after the following year. However, inequalities increased independently of the effect of unemployment. Between 2007 and 2019, after controlling for unemployment, the gap between the most and least deprived areas increased by 15 children per 100 000 per year (95% CI 4 to 26) relative to the 2004-2006 trend., Conclusions: The dramatic increase in the rate of children starting to be looked after has been greater in poorer areas and in areas more deeply affected by recession. But trends in unemployment do not explain the decade-long rise in inequalities, suggesting that other socioeconomic factors, including rising child poverty and reduced spending on children's services, may be fuelling inequalities. Policies to safely reduce the CLA rate should urgently address the social determinants of child health and well-being., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Offensive human waste refers to non-hazardous waste that contains body fluids from non-infectious humans, comprised of post-consumer Absorbent Hygiene Products (AHPs), swabs, dressings, bedding, gloves, and other materials. While this waste category requires more stringent handling, storage and disposal measures than general waste, its non-hazardous nature suggests that there are opportunities for waste valorisation. An inventory of 200 offensive human waste bags collected from various healthcare institutions in South-Eastern England show that about 76% of the waste is comprised of AHPs, most of which are adult incontinence pads and child nappies. Mixed plastics comprised of predominantly HDPE represent 9% of the waste. To evaluate the potentials for offensive human waste valorisation, small-scale separation tests involving artificially-soiled nappies and associated mixed plastic packaging wastes have been performed. Findings suggest that about 50% of the total superabsorbent polymer is recoverable from fluff pulp fractions, recoveries of which are unaffected by the presence of ionic species typically present in human waste. On the other hand, recovery of mixed plastic packaging is more challenging. Overall, however, findings suggest that viable AHP recycling is possible if recyclate materials are targeted towards non-food related markets outlets such as the construction and land remediation sectors., (Copyright © 2019 Elsevier Ltd.

Objectives: To evaluate the psychometric properties of a novel, brief measure of physical, psychological and sexual intimate partner violence (IPV) and estimate the overall prevalence of and gender differences in this violence., Design: Data are from the Avon Longitudinal Study of Parents and Children (ALSPAC), a birth-cohort study., Setting: Avon, UK., Participants: 2128 women and 1145 men who completed the questionnaire assessment at age 21., Outcome Measures: Participants responded to eight items on physical, psychological and sexual IPV victimisation at age 21. Participants indicated whether the violence occurred before age 18 and/or after and led to any of eight negative impacts (eg, fear). We estimated the prevalence of IPV and tested for gender differences using χ 2 or t-tests. We evaluated the IPV victimisation measure based on internal consistency (alpha coefficient), dimensionality (exploratory factor analysis) and convergent validity with negative impacts., Results: Overall, 37% of participants reported experiencing any IPV and 29% experienced any IPV after age 18. Women experienced more frequent IPV, more acts of IPV and more negative impacts than men (p<0.001 for all comparisons). The IPV measure showed high internal consistency (α=0.95), strong evidence for unidimensionality and was highly correlated with negative impacts (r=0.579, p<0.001)., Conclusions: The prevalence of IPV victimisation in the ALSPAC cohort was considerable for both women and men. The strong and consistent gender differences in the frequency and severity of IPV suggest clinically meaningful differences in experiences of this violence. The ALSPAC measure for IPV victimisation was valid and reliable, indicating its suitability for further aetiological investigations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Background: It is unclear whether child maltreatment is increasing or decreasing in England and Wales. More evidence is needed, from multiple sources and over longer periods of time, to explore trends in child maltreatment. We investigated whether the annual incidence of child maltreatment has changed over time, using official record data and time-series methods to establish long-term trends., Methods: In this observational time-series analysis, we used six data sources (Government records for child mortality, police-recorded child homicides, crimes against children, child protection, and children in care; and NSPCC data) to estimate the incidence of child maltreatment in England and Wales and examine long-term trends. We included nationally representative data that could estimate the incidence of child maltreatment for more than 25 years. Our primary outcomes were the number of victims (age <20 years) or perpetrators (age >16 years) of child maltreatment per 12-month period in England, including or excluding Wales. We fitted Poisson regression models with year as the exposure and the number of victims or perpetrators of child maltreatment as the outcome (adjusted for population age-structure and size). When a linear trend was not appropriate, we fitted generalised additive models with penalised splines to visualise trends., Findings: The incidence of child mortality by homicide or assault decreased by 90% (2·7 per 100 000 children) between 1858 and 2016 and the incidence of people guilty of child cruelty or neglect decreased by 83% (6·7 per 100 000 adults) between 1893 and 2016, whereas child protection registrations increased by 182% (328·7 per 100 000 children) between 1988 and 2016. Crimes against children and children entering care increased between 2000 and 2016. In 2016, 40 children died by homicide, with twice as many adolescent (15-19 years) deaths than infant (age <1 year) deaths. In 2016, 67 700 children were placed on the child protection register and neglect and emotional abuse were the most common reasons., Interpretation: Although long-term trends have decreased, child maltreatment remains a major public health problem in England and Wales. Further research is needed to establish whether adolescents are a particularly vulnerable age group and whether neglect and emotional abuse are increasing.

There is a global need to transform cancer follow-up care to address the needs of cancer survivors while efficiently using the health care system to limit the effects of provider shortages, gaps in provider knowledge, and already overburdened clinics; improve the mental health of clinicians; and limit costs to health care systems and patients. England, Northern Ireland, and Australia are implementing an approach that triages patients to personalized follow-up care pathways depending on the types and levels of resources needed for patients' long-term care that has been shown to meet patients' needs, more efficiently use the health care system, and reduce costs. This article discusses lessons learned from these implementation efforts, identifying the necessary components of these care models and barriers and facilitators to implementation of this care. Specifically, the United States and other countries looking to transform follow-up care should consider how to develop six key principles of this care: algorithms to triage patients to pathways; methods to assess patient issues to guide care; remote monitoring systems; methods to support patients in self-management; ways to coordinate care and information exchange between oncology, primary care, specialists, and patients; and methods to engage all stakeholders and secure their ongoing buy-in. Next steps to advance this work in the United States are discussed.

Introduction: There are several brief screening tools for gambling that possess promising psychometric properties, but have uncertain utility in generalist healthcare environments which prioritize prevention and brief interventions. This study describes an examination of the National Opinion Research Centre Diagnostic and Statistical Manual of Mental Disorders Screen for Gambling Problems (NODS-CLiP), in comparison with the Problem Gambling Severity Index (PGSI), when used to operationalize gambling problems across a spectrum of severity., Methods: Data were obtained from 1058 primary care attendees recruited from 11 practices in England who completed various measures including the NODS-CLiP and PGSI. The performance of the former was defined by estimates of sensitivity, specificity, positive predictive values (PPVs), and negative predictive values (NPVs), when PGSI indicators of problem gambling (5+) and any gambling problems (1+), respectively, were reference standards., Results: The NODS-CLiP demonstrated perfect sensitivity for problem gambling, along with high specificity and a NPV, but a low PPV. There was much lower sensitivity when the indicator of any gambling problems was the reference standard, with capture rates indicating only 20% of patients exhibiting low to moderate severity gambling problems (PGSI 1-4) were identified by the NODS-CLiP., Conclusions: The NODS-CLiP performs well when identifying severe cases of problem gambling, but lacks sensitivity for less severe problems and may be unsuitable for settings which prioritize prevention and brief interventions. There is a need for screening measures which are sensitive across the full spectrum of risk and severity, and can support initiatives for improving identification and responses to gambling problems in healthcare settings such as primary care.

Child maltreatment is a major public health problem, which is plagued with research challenges. Good epidemiological data can help to establish the nature and scope of past and present child maltreatment, and monitor its progress going forward. However, high quality data sources are currently lacking for England and Wales. We employed systematic methodology to harness pre-existing datasets (including non-digitalised datasets) and develop a rich data source on the incidence of Child maltreatment over Time (iCoverT) in England and Wales. The iCoverT consists of six databases and accompanying data documentation: Child Protection Statistics, Children In Care Statistics, Criminal Statistics, Homicide Index, Mortality Statistics and NSPCC Statistics. Each database is a unique indicator of child maltreatment incidence with 272 data variables in total. The databases span from 1858 to 2016 and therefore extends current data sources by over 80 years. We present a proof-of-principle analysis of a subset of the data to show how time series methods may be used to address key research challenges. This example demonstrates the utility of iCoverT and indicates that it will prove to be a valuable data source for researchers, clinicians and policy-makers concerned with child maltreatment. The iCoverT is freely available at the Open Science Framework (osf.io/cf7mv)., Competing Interests: The authors have declared that no competing interests exist.

Background: Kidney function reduces with age, increasing the risk of harm from increased blood levels of many medicines. Although estimated glomerular filtration rate (eGFR) is reported for prescribing decisions in those aged ≥65 years, creatinine clearance (Cockcroft-Gault) gives a more accurate estimate of kidney function., Aim: To explore the extent of prescribing outside recommendations for people aged ≥65 years with reduced kidney function in primary care and to assess the impact of using eGFR instead of creatinine clearance to calculate kidney function., Design and Setting: A cross-sectional survey of anonymised prescribing data in people aged ≥65 years from all 80 general practices (70 900 patients) in a north of England former primary care trust., Method: The prevalence of prescribing outside recommendations was analysed for eight exemplar drugs. Data were collected for age, sex, actual weight, serum creatinine, and eGFR. Kidney function as creatinine clearance (Cockcroft-Gault) was calculated using actual body weight and estimated ideal body weight., Results: Kidney function was too low for recommended prescribing in 4-40% of people aged ≥65 years, and in 24-80% of people aged ≥85 years despite more than 90% of patients having recent recorded kidney function results. Using eGFR overestimated kidney function for 3-28% of those aged ≥65 years, and for 13-58% of those aged ≥85 years. Increased age predicted higher odds of having a kidney function estimate too low for recommended prescribing of the study drugs., Conclusion: Prescribing recommendations when kidney function is reduced are not applied for many people aged ≥65 years in primary care. Using eGFR considerably overestimates kidney function for prescribing and, therefore, creatinine clearance (Cockcroft-Gault) should be assessed when prescribing for these people. Interventions are needed to aid prescribers when kidney function is reduced., (© British Journal of General Practice 2018.)

This study compares the cost-effectiveness of treating dorsally displaced distal radial fractures with a volar locking plate and percutaneous fixation. It was performed from the perspective of the National Health Service (NHS) using data from a single-centre randomised controlled trial. In total 130 patients (18 to 73 years of age) with a dorsally displaced distal radial fracture were randomised to treatment with either a volar locking plate (n = 66) or percutaneous fixation (n = 64). The methodology was according to National Institute for Health and Care Excellence guidance for technology appraisals. . There were no significant differences in quality of life scores between groups at any time point in the study. Both groups returned to baseline one year post-operatively. NHS costs for the plate group were significantly higher (p < 0.001, 95% confidence interval 497 to 930). For an additional £713, fixation with a volar locking plate offered 0.0178 additional quality-adjusted life years in the year after surgery. The incremental cost-effectiveness ratio (ICER) for plate fixation relative to percutaneous fixation at list price was £40 068. When adjusting the prices of the implants for a 20% hospital discount, the ICER was £31 898. Patients who underwent plate fixation did not return to work earlier. We found no evidence to support the cost-effectiveness, from the perspective of the NHS, of fixation using a volar locking plate over percutaneous fixation for the operative treatment of a dorsally displaced radial fracture., (©2015 The British Editorial Society of Bone & Joint Surgery.)

Background: The Productive Series is a collection of change programmes designed by the English National Health Service (NHS) Institute for Innovation and Improvement to help frontline healthcare staff improve quality and reduce wasted time, so that this time can be reinvested into time spent with patients. The programmes have been implemented in at least 14 countries around the world. This study examines an implementation of the Productive Community Services programme that took place in a Community healthcare organisation in England from July 2010 to March 2012., Objectives: To explore staff members' perceptions of a Productive Community Services implementation., Design: Cross-sectional interview., Settings: Community Healthcare Organisation in East Anglia, England., Participants: 45 participants were recruited using purposive, snowballing and opportunistic sampling methods to represent five main types of staff group in the organisation; clinical team members, administrative team members, service managers/team leaders, senior managers and software support staff. Team members were recruited on the basis that they had submitted data for at least one Productive Community Services module., Methods: Semi-structured individual and group interviews were carried out after the programme concluded and analysed using thematic analysis., Results: This report focuses on six of the themes identified. The analysis found that communication was not always effective, and there was a lack of awareness, knowledge and understanding of the programme. Many staff did not find the Productive Community Services work relevant, and although certain improvements were sustained, suboptimal practices crept back. Although negative outcomes were reported, such as the programme taking time away from patients initially, many benefits were described including improved stock control and work environments, and better use of the Electronic Patient Record system., Conclusions: One of the themes identified highlighted the positive perceptions of the programme, however a focus on five other themes indicate that important aspects of the implementation could have been improved. The innovation and implementation literature already addresses the issues identified, which suggests a gap between theory and practice for implementation teams. A lack of perceived relevance also suggests that similar programmes need to be made more easily adaptable for the varied specialisms found in Community Services. Further research on Productive Community Services implementations and knowledge transfer is required, and publication of studies focusing on the less positive aspects of implementations may accelerate this process., (Copyright © 2015 Elsevier Ltd.

Objectives: To explore the change in direct medical costs associated with inflammatory polyarthritis (IP) 10 to 15 years after its onset., Methods: Patients from the Norfolk Arthritis Register who had previously participated in a health economic study in 1999 were traced 10 years later and invited to participate in a further prospective questionnaire-based study. The study was designed to identify direct medical costs and changes in health status over a 6-month period using previously validated questionnaires as the primary source of data., Results: A representative sample of 101 patients with IP from the 1999 cohort provided complete data over the 6-month period. The mean disease duration was 14 years (SD 2.1, median 13.6, interquartile range 12.6-15.4). The mean direct medical cost per patient over the 6-month period was £1496 for IP (inflated for 2013 prices). This compared with £582 (95% CI £355-£964) inflated to 2013 prices per patient with IP 10 years earlier in their disease. The increased cost was largely associated with the use of biologics in the rheumatoid arthritis subgroup of patients (51% of total costs incurred). Other direct cost components included primary care costs (11%), hospital outpatient (19%), day care (12%), and inpatient stay (4%)., Conclusion: The direct healthcare costs associated with IP have more than doubled with increasing disease duration, largely as a result of the use of biologics. The results showed a shift in the direct health costs from inpatient to outpatient service use.

Alcohol-related violence is a pressing public health concern. In 2005, the government of England and Wales took a controversial approach to preventing violence by removing restrictions on opening hours for alcohol outlets, thus increasing the availability of alcohol. The policy aimed to remove fixed closing times, which it claimed was contributing to urban violence occurring at peak closing times. It proposed to reduce violence and disorder by installing systems of 'staggered closing times'. This policy was criticised for overlooking established public health principles prioritising the control of alcohol availability in the prevention of alcohol-related harm. In this study, we treated the removal of trading hour restrictions as a natural experiment to test competing theoretical principles about the relationship between alcohol availability and violence. Our study took place in the City of Manchester over a four-year period 2004-2008. Detailed trading records for over 600 alcohol outlets were obtained, as were police records for all violent incidents. We found considerable variation in the implementation of extended trading hours across the city, which affected area-level exposure of changes in alcohol availability and staggered closing times. To isolate the effect of these changes on violence, we performed a dose-response analysis to examine whether improved staggering of closing hours (or increased alcohol availability) was associated with decreases in violence. We found no evidence to support the government-proposed hypothesis that staggered closing reduces violence. We also found no support for the alternative hypothesis; that increase alcohol availability would result in increased violence. This study provides an example of how better evidence can be generated from natural experiments by placing added emphasis on theory, causal mechanisms and implementation science., (Copyright © 2013 Elsevier Ltd.

Vascular calcification (VC) strongly correlates with declining renal function and contributes to the high morbidity and mortality of patients with CKD (chronic kidney disease). It is closely regulated by circulating factors but little is known about the capacity of serum from patients to induce calcification outside the disease setting, which we now define as the calcific potential of serum. We have therefore examined the ability of serum from age- and sex-matched subjects with and without advancing CKD to induce calcification of cultured SMCs (smooth muscle cells). Samples from patients with CKD induced significant calcification compared with controls. More importantly, samples from patients on haemodialysis induced significantly higher calcification than those with moderate or advanced CKD. The calcification induced by the latter two but not those on haemodialysis could be enhanced with calcium chloride and β-GP (β-glycerophosphate). A positive correlation was evident between measured serum creatinine, phosphate, PTH (parathyroid hormone), OPG (osteoprotegerin) and the degree of calcification in vitro. eGFR (estimated glomerular filtration rate), DBP (diastolic blood pressure), haemoglobin and serum albumin correlated negatively. Stepwise multivariate analysis of log-transformed calcific potential data highlighted serum creatinine, albumin and OPG as significant predictors, explaining approximately 50% of the variation. Thus, other regulators, either not investigated or as yet unidentified, may contribute to the calcification potential of serum in vitro. Furthermore, uraemic serum can induce graded calcification outside of the disease milieu that reflects the degree of kidney impairment in vivo. These findings could have important clinical relevance in terms of developing novel diagnostic and/or therapeutic strategies for subjects with CKD.

Recent recommendations for physicians in the UK outline key aspects of care that should improve patient outcomes and experience in acute hospital care. Included in these recommendations are Consultant patterns of work to improve timeliness of clinical review and improve continuity of care. This study used a contemporaneous validated survey compared with clinical outcomes derived from Hospital Episode Statistics, between April 2009 and March 2010 from 91 acute hospital sites in England to evaluate systems of consultant cover for acute medical admissions. Clinical outcomes studied included adjusted case fatality rates (aCFR), including the ratio of weekend to weekday mortality, length of stay and readmission rates. Hospitals that had an admitting Consultant presence within the Acute Medicine Unit (AMU, or equivalent) for a minimum of 4 hours per day (65% of study group) had a lower aCFR compared with hospitals that had Consultant presence for less than 4 hours per day (p<0.01) and also had a lower 28 day re-admission rate (p<0.01). An 'all inclusive' pattern of Consultant working, incorporating all the guideline recommendations and which included the minimum Consultant presence of 4 hours per day (29%) was associated with reduced excess weekend mortality (p<0.05). Hospitals with >40 acute medical admissions per day had a lower aCFR compared to hospitals with fewer than 40 admissions per day (p<0.03) and had a lower 7 day re-admission rate (p<0.02). This study is the first large study to explore the potential relationships between systems of providing acute medical care and clinical outcomes. The results show an association between well-designed systems of Consultant working practices, which promote increased patient contact, and improved patient outcomes in the acute hospital setting.

Unlike other industrialised countries, the UK deferred the routine introduction of disease-modifying therapies (DMTs) for multiple sclerosis (MS) in favour of an experiment. Between 2002 and 2005, MS sufferers were identified, were offered DMTs only if deemed suitable by their physicians, and were monitored thereafter to assess long-term outcomes. It has been demonstrated for other therapies that judgements about suitability to receive treatment are conditioned by the patient's deprivation status. We hypothesised that this would have been the case for DMTs also. Using individual patient data for samples in Nottingham and in Glasgow, we matched patients' postcodes of residence with deprivation scores and confirmed that patients from more deprived areas were less likely to have been prescribed DMTs. A more detailed analysis of the Nottingham data revealed two channels through which this outcome was effected. First, people from less-deprived areas were more likely to possess clinical characteristics, such as less severe disease severity and shorter duration of the disease, that enhanced their suitability for treatment. Second, the analysis of the clinical notes detailing patients' correspondence with the medical teams suggested that less-deprived people were more able to exercise a voice capable of influencing physicians' prescribing decisions.

Background and Purpose: Procedures requiring specific skill sets often have been shown to depend on institutional volume, that is, centers receiving a higher volume observe better outcomes in those patients. This relationship recently has been shown to exist for subarachnoid hemorrhage(SAH) patients in a large study in the United States. We aim to examine this relationship for SAH patients in England, restricting analysis to specialist neurosurgical units., Methods: Aggregate counts of patients with SAH in 25 specialist neuroscience centers in England, from 2005 to 2011, were obtained from the Hospital Episode Statistics database maintained by the National Health Service Information Center. These data were linked with national mortality statistics to obtain counts of deaths. Poisson regression was used to investigate the relationship between institutional caseload of SAH and 6-month mortality from any cause. Six-month mortality rates and mortality ratios were computed., Results: Annual institutional caseload of admissions with SAH was inversely related to 6-month mortality (P=0.009; r(2)=0.26). Each 100-patient increase in annual patient volume was associated with a 24% reduction in mortality (adjusted mortality ratio, 0.76; confidence interval, 0.67-0.87). This relationship was consistent across the entire range of annual institutional caseloads examined (29-367 cases for the lowest and highest volumes seen in a single center in 1 year)., Conclusions: Our results provide support for management of SAH at high-volume centers and suggest that health care policy in this setting should pursue regionalization while ensuring an adequate geographic spread of access to care.

In female sexually transmitted infection clinic attendees, Mycoplasma genitalium was more frequently detected using vaginal (53/73) versus endocervical (43/73) specimens. In women without other sexually transmitted infections, M. genitalium detection (N = 44) was associated with age ≤22 years (odds ratio, 2.53; P = 0.006) and clinical evidence of cervicitis (odds ratio, 2.11; P = 0.03).

Background: UK policy expects health professionals to involve patients in decisions about their care (including medicines use) and, at the same time, to follow prescribing guidelines. The compatibility of these approaches is unclear., Aim: To explore the relationship between prescribing guidelines and patient-partnership by exploring the attitudes of patients, GPs and primary care trust (PCT) prescribing advisors., Design and Setting: A mixed-methods study using qualitative, semi-structured interviews followed by a quantitative, questionnaire survey in primary care in Northern England., Method: Interviews were conducted with 14 patients taking a statin or a proton pump inhibitor, eight GPs and two prescribing advisors. A multi-variate sampling strategy was used. Qualitative findings were analysed using framework analysis. Questionnaires based on themes derived from the interviews were distributed to 533 patients and 305 GPs of whom 286 (54%) and 142 (43%) responded., Results: Areas of tension between guidelines and patient partnership were identified, including potential damage to trust in the doctor and reduced patient choice, through the introduction of the policy maker as a third stakeholder in prescribing decisions. Other areas of tension related to applying single condition guidelines to patients with multiple illnesses, competition for doctors' time and the perception of cost containment. Many GPs coped with these tensions by adopting a flexible approach or prioritising the doctor-patient relationship over guidelines., Conclusion: Rigidly applied guidelines can limit patient choice and may damage the doctor-patient relationship. GPs need flexibility in order to optimise the implementation of prescribing guidelines, while responding to individuals' needs and preferences.

Objective: It has been found that women with rheumatoid arthritis (RA) have a poorer prognosis than men. However, the impact of age at symptom onset is unclear. We investigated the relationship between these factors and functional disability in patients with recent-onset inflammatory polyarthritis (IP)., Methods: A total of 3,666 patients (66% women) were registered with the Norfolk Arthritis Register between 1990 and 2008. Functional disability was assessed using the Health Assessment Questionnaire (HAQ), adjusted for age at HAQ completion. Linear random-effects models were used to examine HAQ score over time, by sex and age at symptom onset (early = age <55 years, late = age 55-74 years, very late = age ≥75 years)., Results: Women had higher HAQ scores over time than men (mean difference 0.29; 95% confidence interval [95% CI] 0.25, 0.34). Men with late-onset IP had lower baseline HAQ scores than men with early onset (mean difference -0.14; 95% CI -0.29, -0.001). Women had comparable baseline HAQ scores at all ages of onset. Both sexes showed the greatest rate of disability progression in patients with very late onset. Those with early onset had a steady level of disability over time. Adjustment for treatment received, comorbidities, and RA subgroup analysis produced results that were largely similar to the initial analysis., Conclusion: Female patients have higher HAQ scores than male patients; patients with early symptom onset show the smallest sex difference. Older age at symptom onset is associated with an increasingly steep trajectory of disability progression. The impact of sex on outcome is evident at baseline, whereas the impact of age at symptom onset becomes apparent during long-term followup., (Copyright © 2011 by the American College of Rheumatology.)

Background: Strong correlation between mean intracranial pressure (ICP) and its pulse wave amplitude (AMP) has been demonstrated in different clinical scenarios. We investigated the relationship between invasive mean arterial blood pressure (ABP) and AMP to explore its potential role as a descriptor of cerebrovascular pressure reactivity after traumatic brain injury (TBI)., Methods: We retrospectively analyzed data of patients suffering from TBI with brain monitoring. Transcranial Doppler blood flow velocity, ABP, ICP were recorded digitally. Cerebral perfusion pressure (CPP) and AMP were derived. A new index-pressure-amplitude index (PAx)-was calculated as the Pearson correlation between (averaged over 10 s intervals) ABP and AMP with a 5 min long moving average window. The previously introduced transcranial Doppler-based autoregulation index Mx was evaluated in a similar way, as the moving correlation between blood flow velocity and CPP. The clinical outcome was assessed after 6 months using the Glasgow outcome score., Results: 293 patients were studied. The mean PAx was -0.09 (standard deviation 0.21). This negative value indicates that, on average, an increase in ABP causes a decrease in AMP and vice versa. PAx correlated strong with Mx (R (2) = 0.46, P < 0.0002). PAx also correlated with age (R (2) = 0.18, P < 0.05). PAx was found to have as good predictive outcome value (area under curve 0.71, P < 0.001) as Mx (area under curve 0.69, P < 0.001)., Conclusions: We demonstrated significant correlation between the known cerebral autoregulation index Mx and PAx. This new index of cerebrovascular pressure reactivity using ICP pulse wave information showed to have a strong association with outcome in TBI patients.

Objective: To investigate the relationship between pre-symptom onset live births and functional outcome in women with inflammatory polyarthritis (IP)., Methods: 1872 women with no subsequent pregnancies were registered with the Norfolk Arthritis Register between 1990 and 2004 and followed-up for a median of 5 years. Functional disability over time was assessed by Health Assessment Questionnaire (HAQ). The number and calendar year of past live births were recorded. Differences in HAQ score over time by parity and time since last live birth (latency), adjusted for age and symptom duration, were examined using linear random effects models. The results were then adjusted for a number of potential confounders., Results: 1553 women (83%) had ≥1 live births before symptom onset. The median latency was 26 years (IQR 16-35). Parous women had significantly lower HAQ scores over time than nulliparous women (-0.19, 95% CI -0.32 to -0.06). Increasing latency was associated with increasing HAQ score; the mean HAQ score of women with a latency of approximately 32 years was the same as for nulliparous women. This was independent of autoantibody status, socioeconomic status, smoking history and comorbidity., Conclusion: Parous women who develop IP have better functional outcome over time than nulliparous women who develop IP. The beneficial effect of parity diminishes with time.

Background: In England, two national programmes of HPV vaccination for girls have been instituted, a routine programme for 12- and 13-year-olds and a catch-up programme for 17- and 18-year-olds. Uptake rates across the country have been far from uniform, and this research sought to identify factors explaining the variation in uptake by locality., Methods: An association between uptake, deprivation and ethnic background had been established in pilot research. The present analysis was conducted at an aggregate, Primary Care Trust (PCT), level for the first year of the programmes. Published measures of HPV vaccination uptake, material deprivation, ethnic composition of PCT populations, primary care quality, and uptake of cervical screening and of other childhood immunisations were collated. Strong evidence of collinearity amongst the explanatory variables required a factor analysis to be undertaken. This provided four independent factors, used thereafter in regression models to explain uptake by PCT., Results: The factor analysis revealed that ethnic composition was associated with attitudes towards cervical screening and other childhood vaccinations, whilst material deprivation and quality of primary care were orthogonal. Ethnic composition, early childhood vaccination, cervical screening and primary care quality were found to be influential in predicting uptake in both the routine and the catch-up cohorts, although with a lower degree of confidence in the case of the last two independent variables. Lower primary care quality was significant in explaining a greater fall in vaccination uptake between the first two doses in the catch-up cohort. Greater deprivation was a significant explanatory factor for both uptake and the fall in uptake between doses for the catch-up cohort but not for uptake in the routine cohort., Conclusion: These results for uptake of the first year of the national programme using aggregate data corroborate findings from intentions surveys and pilot studies. Deprivation, the ethnic composition of the population, the effectiveness of primary care and the acceptability of childhood vaccinations are salient factors in explaining local HPV vaccine uptake in England.

Objective: To report the causes of, and ages at, death of subjects in an English colorectal cancer screening trial., Design and Setting: Analysis of 78 708 deaths occurring between 1981 and 2008, within the Nottingham randomised controlled trial of biennial faecal occult blood testing., Main Outcome Measures: Cause of death, age at death by sex and by cause., Results: Significantly more subjects died from verified colorectal cancer in the trial's control group than in the intervention group (3.2% vs 2.9%). For no other major cause of death was the difference in proportion across the two groups statistically significant. Age at death was lower for cancer than for other principal causes, except for ischaemic heart disease among women. However, mean age at death was higher for colorectal cancer than for other cancers, except for prostate cancer among men. Increasing levels of material deprivation significantly lowered the expected ages at death, independently of cause. For both men and women, the mean age at death from all causes for screening participants was higher than that of controls and non-participants. Mean deprivation was lowest among participants. Of those participating in screening, and dying from colorectal cancer, subjects receiving negative test results lived significantly longer than those who received positive test results. However, if dying from other causes, they died at an earlier age., Conclusions: The age at death from colorectal cancer is higher than that of most other cancers. Those accepting a screening invitation live longer than non-participants. In part, this difference is explained by relative deprivation. Among screening participants, the receipt of a positive, as opposed to a negative, test result is associated with a later age at death.

Orthognathic surgery has advanced considerably since its development in the mid-twentieth century, and in most maxillofacial units mandibular and maxillary osteotomies are routine procedures. However, to enable accurate health planning and costing, and to obtain meaningful consent, it is important to have reliable data for duration of operation and inpatient stay. Virtually every aspect of orthognathic surgery has been researched, but we know of no recent studies that have looked specifically at how long the procedures take and how long patients stay in hospital. We retrospectively studied a sample of patients who had had orthognathic operations at six maxillofacial units in the United Kingdom (UK) to assess these measures. We looked at 411 operations which included 139 bilateral sagittal split osteotomies, 53 Le Fort I osteotomies, and 219 bimaxillary osteotomies. The study showed that the mean (SD) operating time for bilateral sagittal split osteotomy is 2h 6min (46min), 1h 54min (45minutes) for Le Fort I osteotomy, and 3h 27min (60min) for bimaxillary osteotomy. The duration of postoperative hospital stay was also measured. Fifty percent of patients spent one night in hospital after bilateral sagittal split osteotomy, whereas 39% and 9% of patients spent two and three nights, respectively. Forty-five percent of patients spent one night in hospital after Le Fort I osteotomy, whereas 34%, 13%, and 2% spent two, three, and four nights, respectively. Forty-one percent of patients spent two nights in hospital after bimaxillary osteotomy, whereas 34%, 21%, and 3% spent one, three, and four nights, respectively. This data provides evidence for national benchmarks., (Copyright 2009 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.)

Background: High rates of long-term antidepressant prescribing have been identified in the older population., Aims: To explore the attitudes of older patients and their GPs to taking long-term antidepressant therapy, and their accounts of the influences on long-term antidepressant use., Design of Study: Qualitative study using in-depth semi-structured interviews., Setting: One primary care trust in North Bradford., Method: Thirty-six patients aged > or =75 years and 10 GPs were interviewed. Patients were sampled to ensure diversity in age, sex, antidepressant type, and home circumstances., Results: Participants perceived significant benefits and expressed little apprehension about taking long-term antidepressants, despite being aware of the psychological and social factors involved in onset and persistence of depression. Barriers to discontinuation were identified following four themes: pessimism about the course and curability of depression; negative expectations and experiences of ageing; medicine discontinuation perceived by patients as a threat to stability; and passive (therapeutic momentum) and active (therapeutic maintenance) decisions to accept the continuing need for medication., Conclusion: There is concern at a public health level about high rates of long-term antidepressant prescribing, but no evidence was found of a drive for change either from the patients or the doctors interviewed. Any apprehension was more than balanced by attitudes and behaviours supporting continuation. These findings will need to be incorporated into the planning of interventions aimed at reducing long-term antidepressant prescribing in older people.

Background: Cancer screening programmes in England are publicly-funded. Professionals' beliefs in the public health benefits of screening can conflict with individuals' entitlements to exercise informed judgement over whether or not to participate. The recognition of the importance of individual autonomy in decision making requires greater understanding of the knowledge, attitudes and beliefs upon which people's screening choices are founded. Until recently, the technology available required that cancer screening be confined to women. This study aimed to discover whether male and female perceptions of cancer and of screening differed., Methods: Data on the public's cancer beliefs were collected by means of a postal survey (anonymous questionnaire). Two general practices based in Nottingham and in Mansfield, in east-central England, sent questionnaires to registered patients aged 30 to 70 years. 1,808 completed questionnaires were returned for analysis, 56.5 per cent from women., Results: Women were less likely to underestimate overall cancer incidence, although each sex was more likely to cite a sex-specific cancer as being amongst the most common cancer site. In terms of risk factors, men were most uncertain about the role of stress and sexually-transmitted diseases, whereas women were more likely to rate excessive alcohol and family history as major risk factors. The majority of respondents believed the public health care system should provide cancer screening, but significantly more women than men reported having benefiting from the nationally-provided screening services. Those who were older, in better health or had longer periods of formal education were less worried about cancer than those who had illness experiences, lower incomes, or who were smokers. Actual or potential participation in bowel screening was higher amongst those who believed bowel cancer to be common and amongst men, despite women having more substantial worries about cancer than men., Conclusion: Our results suggest that men's and women's differential knowledge of cancer correlates with women's closer involvement with screening. Even so, men were neither less positive about screening nor less likely to express a willingness to participate in relevant screening in the future. It is important to understand gender-related differences in knowledge and perceptions of cancer, if health promotion resources are to be allocated efficiently.

Background: Although the association between poor health and deprivation is well-founded, a 'Scottish effect' has been observed, whereby the level of health appears even poorer than Scotland's higher level of deprivation should warrant. We consider whether 'Scottish effects' also occur within the regions of England and Wales., Method: Using ward-level data from the national census, we regress healthy life expectancies relative to total life expectancies on Carstairs deprivation scores, households' average disposable incomes, geo-spatial characteristics and regional dummy variables., Results: Higher incomes and lower Carstairs scores are each associated with longer proportions of lives expected to be spent in good health or without long-standing illness. Relative to the London region, the coefficients on the regional dummies are uniformly negative and mostly significant., Conclusions: There exist differences in relative health expectancies between the regions of England and Wales, which are not fully explained by the differences in socio-economic circumstances. Conventional deprivation measures tend to understate the poorer health performances of the more deprived regions (Wales and the north of England), and the understatement increases with deprivation. The exception to the rule is London, where health expectancies are superior to those which deprivation leads us to expect.
