Evaluation of the impact of the NICE head injury guidelines on inpatient mortality from traumatic brain injury : an interrupted time series analysis

Objective To evaluate the impact of National Institute for Health and Care Excellence (NICE) head injury guidelines on deaths and hospital admissions caused by traumatic brain injury (TBI). Setting All hospitals in England between 1998 and 2017. Participants Patients admitted to hospital or who died up to 30 days following hospital admission with International Classification of Diseases (ICD) coding indicating the reason for admission or death was TBI. Intervention An interrupted time series analysis was conducted with intervention points when each of the three guidelines was introduced. Analysis was stratified by guideline recommendation specific age groups (0–15, 16–64 and 65+). Outcome measures The monthly population mortality and admission rates for TBI. Study design An interrupted time series analysis using complete Office of National Statistics cause of death data linked to hospital episode statistics for inpatient admissions in England. Results The monthly TBI mortality and admission rates in the 65+ age group increased from 0.5 to 1.5 and 10 to 30 per 100 000 population, respectively. The increasing mortality rate was unaffected by the introduction of any of the guidelines. The introduction of the second NICE head injury guideline was associated with a significant reduction in the monthly TBI mortality rate in the 16–64 age group (-0.005; 95% CI: −0.002 to −0.007). In the 0–15 age group the TBI mortality rate fell from around 0.05 to 0.01 per 100 000 population and this trend was unaffected by any guideline. Conclusion The introduction of NICE head injury guidelines was associated with a reduced admitted TBI mortality rate after specialist care was recommended for severe TBI. The improvement was solely observed in patients aged 16–64 years. The cause of the observed increased admission and mortality rates in those 65+ and potential treatments for TBI in this age group require further investigation

Advancing public health policy making through research on the political strategies of alcohol industry actors

Development and implementation of evidence-based policies is needed in order to ameliorate the rising toll of non-communicable diseases (NCDs). Alcohol is a key cause of the mortality burden and alcohol policies are under-developed. This is due in part to the global influence of the alcohol industry. We propose that a better understanding of the methods and the effectiveness of alcohol industry influence on public health policies will support efforts to combat such influence, and advance global health. Many of the issues on the research agenda we propose will inform, and be informed by, research into the political influence of other commercial actors

The Effects of Caring for Young Children with Developmental Disabilities on Mothers’ Health and Healthcare Use : Analysis of Primary Care Data in the Born in Bradford Cohort

We explored the association between caregiving for preschool children with developmental disabilities and maternal health and healthcare use using linked primary care and Born in Bradford birth cohort data. Adjusting for prenatal health, healthcare use and socioeconomic status, mothers who were caregivers were more likely than other mothers to have symptoms of psychological distress (odds ratio 1.24; 95% CI 1.01, 1.53), exhaustion (1.42; 1.12, 1.80) and possibly head and musculoskeletal pain (1.18; 0.97, 1.43). Despite the higher prevalence of symptoms, they did not access healthcare services more and may seek healthcare for psychological distress less often (0.64; 0.40, 1.02). In general, socioeconomic disadvantage was associated with worse health. Pakistani ethnicity (versus white British) and prenatal consultation were strongly associated with higher postnatal consultation rates. Prenatal ill health, healthcare use and socioeconomic status are important factors in the detection of postnatal ill health via primary care services. If caregiver burden and the risk of under-detecting (and thus under treating) caregiver ill health is not addressed during the preschool period health inequalities between caregivers and other mothers and their families may persist and grow. The health of mothers of young disabled children, in particular their unmet health needs, warrants attention in research and clinical practice

Starting school: educational development as a function of age of entry and prematurity

Objective: To estimate the impact on early development of prematurity and summer birth and the potential ‘double disadvantage’ created by starting school a year earlier than anticipated during pregnancy, due to being born preterm. Design, setting and patients: We investigated the impact of gestational and school-entry age on the likelihood of failing to achieve a ‘Good Level of Development’ (GLD) on the Early Years Foundation Stage Profile in 5-year-old children born moderate-to-late preterm using data from the Born in Bradford longitudinal birth cohort. We used hierarchical logistic regression to control for chronological maturity, and perinatal and socioeconomic factors. Results: Gestational age and school-entry age were significant predictors of attaining a GLD in the 10 337 children who entered school in the correct academic year given their estimated date of delivery. The odds of not attaining a GLD increased by 1.09 (95% CI 1.06 to 1.11) for each successive week born early and by 1.17 for each month younger within the year group (95% CI 1.16 to 1.18). There was no interaction between these two effects. Children starting school a year earlier than anticipated during pregnancy were less likely to achieve a GLD compared with (1) other children born preterm (fully adjusted OR 5.51 (2.85–14.25)); (2) term summer births (3.02 (1.49–6.79)); and (3) preterm summer births who remained within their anticipated school-entry year (3.64 (1.27–11.48)). Conclusions: These results confirm the developmental risks faced by children born moderate-to-late preterm, and—for the first time—illustrate the increased risk associated with ‘double disadvantage’

Blood pressure change across pregnancy in white British and Pakistani women: analysis of 1 data from the Born in Bradford cohort

The incidence of gestational hypertension (GH) and pre-eclampsia (PE) is increasing. Use of blood pressure (BP) change patterns may improve early detection of BP abnormalities. We used Linear spline random-effects models to estimate BP patterns across pregnancy for white British and Pakistani women. Pakistani women compared to white British women had lower BP during the first two trimesters of pregnancy, irrespective of the development of GH or PE or presence of a risk factor. Pakistani compared to white British women with GH and PE showed steeper BP increases towards the end of pregnancy. Pakistani women were half as likely to develop GH, but as likely to develop PE than white British women. To conclude; BP trajectories differ by ethnicity. Because GH developed evenly from 20 weeks gestation, and PE occurred more commonly after 36 weeks in both ethnic groups, the lower BP up to the third trimester in Pakistani women resulted in a lower GH rate, whereas PE rates, influenced by the steep third trimester BP increase were similar. Criteria for diagnosing GH and PE may benefit from considering ethnic differences in BP change across pregnancy

Prevalence of, and Risk Factors for, Presenting Visual Impairment : Findings from a vision screening programme based on UK NSC guidance in a multi-ethnic population

YesPurpose: To determine presenting visual acuity levels and explore the factors associated with failing vision screening in a multi-ethnic population of UK children aged 4–5 years. Methods: Visual acuity (VA) using the logMAR Crowded Test was measured in 16,541 children in a population-based vision screening programme. Referral for cycloplegic examination was based on national recommendations (>0.20logMAR in one or both eyes). Presenting visual impairment (PVI) was defined as VA >0.3logMAR in the better eye. Multivariable logistic regression was used to assess the association of ethnicity, maternal, and early-life factors with failing vision screening and PVI in participants of the Born in Bradford birth cohort. Results: In total, 2467/16,541 (15%) failed vision screening, 732 (4.4%) had PVI. Children of Pakistani (OR: 2.49; 95% CI: 1.74–3.60) and other ethnicities (OR: 2.00; 95% CI: 1.28–3.12) showed increased odds of PVI compared to white children. Children born to older mothers (OR: 1.63; 95% CI: 1.19–2.24) and of low birth weight (OR: 1.52; 95% CI: 1.00–2.34) also showed increased odds. Follow-up results were available for 1068 (43.3%) children, 993 (93%) were true positives; 932 (94%) of these had significant refractive error. Astigmatism (>1DC) (44%) was more common in children of Pakistani ethnicity and hypermetropia (>3.0DS) (27%) in white children (Fisher’s exact, p < 0.001). Conclusions: A high prevalence of PVI is reported. Failing vision screening and PVI were highly associated with ethnicity. The positive predictive value of the vision screening programme was good, with only 7% of children followed up confirmed as false positives.National Institute for Health Research Post-Doctoral Fellowship Award (PDF-2013-06-050); The Born in Bradford study presents independent research commissioned by the National Institute for Health Research Collaboration for Applied Health Research and Care (NIHR CLAHRC) and the Programme Grants for Applied Research funding scheme (RP-PG-0407-10044)
