Published: February 2018

ObjectivesTo determine whether introduction or withdrawal of a maternal financial incentive was associated with changes in timing of first attendance for antenatal care (‘booking’), or incidence of small for gestational age.DesignA natural experimental evaluation using interrupted time series analysis.SettingA hospital-based maternity unit in the north of England.Participants34 589 women (and their live-born babies) who delivered at the study hospital and completed the 25th week of pregnancy in the 75 months before (January 2003 to March 2009), 21 months during (April 2009 to December 2010) and 36 months after (January 2011 to December 2013) the incentive was available.InterventionThe Health in Pregnancy Grant was a financial incentive of £190 ($235; €211) payable to pregnant women in the UK from the 25th week of pregnancy, contingent on them receiving routine antenatal care.Primary and secondary outcome measuresThe primary outcome was mean gestational age at booking. Secondary outcomes were proportion of women booking by 10, 18 and 25 weeks’ gestation; and proportion of babies that were small for gestational age.ResultsBy 21 months after introduction of the grant (ie, immediately prior to withdrawal), compared with what was predicted given prior trends, there was an reduction in mean gestational age at booking of 4.8 days (95% CI 2.3 to 8.2). The comparable figure for 24 months after withdrawal was an increase of 14.0 days (95% CI 2.8 to 16.8). No changes in incidence of small for gestational age babies were seen.ConclusionsThe introduction of a universal financial incentive for timely attendance at antenatal care was associated with a reduction in mean gestational age at first attendance, but not the proportion of babies that were small for gestational age. Future research should explore the effects of incentives offered at different times in pregnancy and of differing values; and how stakeholders view such incentives.

ObjectivesTo determine whether implementation of a case-based payment system changed all-cause readmission rates in the 30 days following discharge after surgery, we analysed all surgical procedures performed in all hospitals in France before (2002–2004), during (2005–2008) and after (2009–2012) its implementation.SettingOur study is based on claims data for all surgical procedures performed in all acute care hospitals with >300 surgical admissions per year (740 hospitals) in France over 11 years (2002–2012; n=51.6 million admissions).InterventionsWe analysed all-cause 30-day readmission rates after surgery using a logistic regression model and an interrupted time series analysis.ResultsThe overall 30-day all-cause readmission rate following discharge after surgery increased from 8.8% to 10.0% (P<0.001) for the public sector and from 5.9% to 8.6% (P<0.001) for the private sector. Interrupted time series models revealed a significant linear increase in readmission rates over the study period in all types of hospitals. However, the implementation of case-based payment was only associated with a significant increase in rehospitalisation rates for private hospitals (P<0.001).ConclusionIn France, the increase in the readmission rate appears to be relatively steady in both the private and public sector but appears not to have been affected by the introduction of a case-based payment system after accounting for changes in care practices in the public sector.

Published: February 2018

ObjectivesThis study aimed to establish the association between timing and provision of palliative care (PC) and quality of end-of-life care indicators in a population of patients dying of cancer.SettingThis study uses linked cancer patient data from the National Cancer Registry, the electronic medical record system used in primary care (SystmOne) and the electronic medical record system used within a specialist regional cancer centre. The population resided in a single city in Northern England.ParticipantsRetrospective data from 2479 adult cancer decedents who died between January 2010 and February 2012 were registered with a primary care provider using the SystmOne electronic health record system, and cancer was certified as a cause of death, were included in the study.ResultsLinkage yielded data on 2479 cancer decedents, with 64.5% who received at least one PC event. Decedents who received PC were significantly more likely to die in a hospice (39.4% vs 14.5%, P<0.005) and less likely to die in hospital (23.3% vs 40.1%, P<0.05), and were more likely to receive an opioid (53% vs 25.2%, P<0.001). PC initiated more than 2 weeks before death was associated with avoiding a hospital death (≥2 weeks, P<0.001), more than 4 weeks before death was associated with avoiding emergency hospital admissions and increased access to an opioid (≥4 weeks, P<0.001), and more than 33 weeks before death was associated with avoiding late chemotherapy (≥33 weeks, no chemotherapy P=0.019, chemotherapy over 4 weeks P=0.007).ConclusionFor decedents with advanced cancer, access to PC and longer duration of PC were significantly associated with better end-of-life quality indicators.

Published: February 2018

IntroductionThe aim of the study is to analyse the prevalence of smoking among resident physicians at a regional university hospital. In addition, we examined the trends in the smoking behaviour of physicians in relation to results obtained in other studies carried out previously at this hospital, as well as those published nationally and internationallyMethodA cross-sectional observational study evaluating tobacco consumption in young physicians was carried out at the level of secondary healthcare in a regional university hospital in Cordoba, Spain. All the study subjects were resident physicians who underwent a mandatory preliminary occupational health examination between 2012 and 2016. There was no sampling selection as anyone who took this examination was considered to be within the target population. We calculated the proportions of smokers, former smokers and non-smokers, with 95% CIs. Univariate and multivariate analyses (binary logistic regression) were used to analyse the results (P<0.05).ResultsThe response rate was 99.4%, with a sample size of 324 out of a possible 326 physicians. The average age was 28.6±3.7—DT—(95% CI 28.2 to 29.0), and 62.3% (202/324; 95% CI 57.3 to 67.2) were women. Smoking prevalence was 6.5% (21/324; 95% CI 3.5 to 9.3) with a further 5.2% (17/324; 95% CI 2.7 to 7.8) being ex-smokers. There were no significant differences in the prevalence of tobacco consumption according to age (P=0.266), sex (9.0% for men and 5.0% for women; P=0.128), medical specialty (P=0.651) or year of residency (P=0.975). A 52.7% decline in the number of young physician smokers was noted between 1986 and 2016 (95% CI −44.0 to −63.5), together with a 64.4% increase in non-smokers (95% CI 55.2 to 77.3).ConclusionsWe observed a significantly low prevalence of tobacco use among trainee physicians in the cohort, an effect of new antismoking laws, with positive role model implications for new physicians and medical students.

ObjectivesAcute rhinosinusitis (ARS) has a high incidence. Diagnosis is clinical, and evolution is mostly self-limited. The aim of this study was to describe the sociodemographic characteristics and use of diagnostic tools and medications in patients with ARS.DesignThis is a prospective observational study in real-life clinical practice.SettingPatients with clinical diagnosis of ARS (n=2610) were included from ear, nose and throat clinics in Spain. A second visit at resolution was done.ParticipantsPatients were classified according to the duration of symptoms: viral ARS (≤10 days), postviral ARS (>10 days, ≤12 weeks) and chronic rhinosinusitis (>12 weeks).Main outcome measuresSociodemographic characteristics, symptoms, disease severity, quality of life (Sino-Nasal Outcome Test-16), used diagnostic tools and medications, and the management performed by primary care physicians (PCPs) and by otorhinolaryngologists (ORLs) were assessed.ResultsOf the patients 36% were classified as having viral ARS, 63% postviral ARS and 1% as chronic rhinosinusitis. Working in a poorly air-conditioned environment was a risk factor (OR: 2.26, 95% CI 1.27 to 4.04) in developing postviral ARS. A higher number of diagnostic tools (rhinoscopy/endoscopy: 80% vs 70%; plain X-ray: 70% vs 55%; CT scan: 22% vs 12%; P<0.0001) were performed in postviral than viral cases. PCPs performed more X-rays than ORLs (P<0.0001). Patients, more those with postviral than viral ARS, received a high number of medications (oral antibiotics: 76% vs 62%; intranasal corticosteroids: 54% vs 38%; antihistamines: 46% vs 31%; mucolytic: 48% vs 60%; P<0.0001). PCPs prescribed more antibiotics, antihistamines and mucolytics than ORLs (P<0.0068). More patients with postviral than viral ARS reported symptoms of potential complications (1.5% vs 0.4%; P=0.0603). Independently of prescribed medications, quality of life was more affected in patients with postviral (38.7±14.2 vs 36.0±15.3; P=0.0031) than those with viral ARS. ARS resolution was obtained after 6.04 (viral) and 16.55 (postviral) days, with intranasal corticosteroids being associated with longer (OR: 1.07, 95% 1.02 to 1.12) and phytotherapy with shorter (OR: 0.95, 95% CI 0.91 to 1.00) duration.ConclusionsThere is a significant overuse of diagnostic tools and prescribed medications, predominantly oral antibiotics, by PCPs and ORLs, for viral and postviral ARS.
Protein-enriched, milk-based supplement to counteract sarcopenia in acutely ill geriatric patients offered resistance exercise training during and after hospitalisation: study protocol for a randomised, double-blind, multicentre trial

Published: February 2018

IntroductionAge-related loss of muscle mass and strength, sarcopaenia, burdens many older adults. The process is accelerated with bed rest, protein intakes below requirements and the catabolic effect of certain illnesses. Thus, acutely ill, hospitalised older adults are particularly vulnerable. Protein supplementation can preserve muscle mass and/or strength and, combining this with resistance exercise training (RT), may have additional benefits. Therefore, this study investigates the effect of protein supplementation as an addition to offering RT among older adults while admitted to the geriatric ward and after discharge. This has not previously been investigated.Methods and analysisIn a block-randomised, double-blind, multicentre intervention study, 165 older adults above 70 years, fulfilling the eligibility criteria, will be included consecutively from three medical departments (blocks of n=20, stratified by recruitment site). After inclusion, participants will be randomly allocated (1:1) to receive either ready-to-drink, protein-enriched, milk-based supplements (a total of 27.5 g whey protein/day) or isoenergetic placebo products (<1.5 g protein/day), twice daily as a supplement to their habitual diet. Both groups will be offered a standardised RT programme for lower extremity muscle strength (daily while hospitalised and 4×/week after discharge). The study period starts during their hospital stay and continues 12 weeks after discharge. The primary endpoint is lower extremity muscle strength and function (30 s chair-stand-test). Secondary endpoints include muscle mass, measures of physical function and measures related to cost-effectiveness.Ethics and disseminationApproval is given by the Research Ethic Committee of the Capital Region of Denmark (reference no. H-16018240) and the Danish Data Protection Agency (reference no. HGH-2016-050). There are no expected risks associated with participation, and each participant is expected to benefit from the RT. Results will be published in peer-reviewed international journals and presented at national and international congresses and symposiums.Trial registration numberNCT02717819 (9 March 2016).

Published: February 2018

IntroductionThe introduction of biological disease-modifying antirheumatic drugs (bDMARDs) has improved the treatment of inflammatory rheumatic diseases dramatically. However, bDMARD treatment failure occurs in 30%–40% of patients due to lack of effect or adverse events, and the tools to predict treatment outcomes in individual patients are currently limited. The objective of the present study is to identify diagnostic, prognostic and predictive biomarkers, which can be used to (1) diagnose inflammatory rheumatic diseases early in the disease course with high sensitivity and specificity, (2) improve prognostication or (3) predict and monitor treatment effectiveness and tolerability for the individual patient.Methods and analysisThe present study is an observational and translational open cohort study with prospective collection of clinical data and biological materials (primarily blood) in patients with inflammatory rheumatic diseases treated in routine care. Patients contribute with one cross-sectional blood sample and/or are enrolled for longitudinal follow-up on initiation of a new DMARD (blood sampling after 0, 3, 6, 12, 24, 36, 48, 60 months of treatment). Other biological materials will be collected when accessible and relevant. Demographics, disease characteristics, comorbidities and lifestyle factors are registered at inclusion; DMARD treatment and outcomes are collected repeatedly during follow-up. Currently (July 2017), >5000 samples from approximately 3000 patients have been collected. Data will be analysed using appropriate statistical analyses.Ethics and disseminationThe protocol is approved by the Danish Ethics Committee and the Danish Data Protection Agency. Participants give written and oral informed consent. Biomarkers will be evaluated and published according to the Reporting Recommendations for Tumour Marker (REMARK) prognostic studies, Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) and the Standards for Reporting of Diagnostic Accuracy (STARD) guidelines. Results will be published in peer-reviewed scientific journals and presented at international conferences.Trial registration numberNCT03214263.

Published: February 2018

IntroductionStroke events deeply affect not only the stroke survivor but also often the quality of life and physical and psychological health of the family and friends who care for them. There is a need for further information about the unmet needs of these informal carers in order to develop support services and interventions. The primary objective of this review is to report and synthesise the research describing the unmet needs of carers of stroke survivors.Methods and analysisA systematic review of quantitative and qualitative studies that report on the unmet needs of carers will be conducted. The following databases will be searched for relevant articles: MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, EMBASE, Allied and Complementary Medicine Database and Scopus. No publication date constraints will be applied. Studies will be limited to those published in English and conducted among humans. Eligible studies will report on the unmet needs of informal carers of stroke survivors, defined as family members, friends and other unpaid caregivers. Studies which focus on formal, clinical or medical caregivers will be excluded. A narrative synthesis and pooled analysis of the main outcomes will be reported.Ethics and disseminationThis review will be submitted to a peer-reviewed journal. Our findings are expected to provide new insights into the unmet needs of stroke survivors’ carers. Knowledge about the unmet needs of carers will inform the development and refinement of interventions and services to address these needs and better support carers of stroke survivors. The findings of this systematic review will be disseminated publicly and in peer-reviewed journals and may be the topic of research presentations.Trial registration numberCRD42017067391.
Monocular and binocular visual impairment in the UK Biobank study: prevalence, associations and diagnoses

Published: February 2018

ObjectiveTo determine the prevalence of, associations with and diagnoses leading to mild visual impairment or worse (logMAR >0.3) in middle-aged adults in the UK Biobank study.Methods and analysisPrevalence estimates for monocular and binocular visual impairment were determined for the UK Biobank participants with fundus photographs and spectral domain optical coherence tomography images. Associations with socioeconomic, biometric, lifestyle and medical variables were investigated for cases with visual impairment and matched controls, using multinomial logistic regression models. Self-reported eye history and image grading results were used to identify the primary diagnoses leading to visual impairment for a sample of 25% of cases.ResultsFor the 65 033 UK Biobank participants, aged 40–69 years and with fundus images, 6682 (10.3%) and 1677 (2.6%) had mild visual impairment or worse in one or both eyes, respectively. Increasing deprivation, age and ethnicity were independently associated with both monocular and binocular visual impairment. No primary diagnosis for the recorded level of visual impairment could be identified for 49.8% of eyes. The most common identifiable diagnoses leading to visual impairment were cataract, amblyopia, uncorrected refractive error and vitreoretinal interface abnormalities.ConclusionsThe prevalence of visual impairment in the UK Biobank study cohort is lower than for population-based studies from other industrialised countries. Monocular and binocular visual impairment are associated with increasing deprivation, age and ethnicity. The UK Biobank dataset does not allow confident identification of the causes of visual impairment, and the results may not be applicable to the wider UK population.

Published: February 2018

BackgroundMicrosatellite instability is reflective of a deficient mismatch repair system (dMMR), which may be due to either sporadic or germline mutations in the relevant mismatch repair (MMR) gene. MMR status is frequently determined by immunohistochemistry (IHC) for mismatch repair proteins (MMRPs) on colorectal cancer (CRC) resection specimens. However, IHC testing performed on endoscopic biopsy may be as reliable as that performed on surgical resections.AimWe aimed to evaluate the reliability of MMR IHC staining on preoperative CRC endoscopic biopsies compared with matched-surgical resection specimens.MethodsA retrospective search of our institution’s histopathology electronic database was performed. Patients with CRC who had MMR IHC performed on both their preoperative endoscopic biopsy and subsequent resection from January 2010 to January 2016 were included. Concordance of MMR staining between biopsy and resection specimens was assessed.ResultsFrom 2000 to 2016, 53 patients had MMR IHC performed on both their preoperative colorectal endoscopic biopsy and resection specimens; 10 patients (18.87%) demonstrated loss of ≥1 MMRP on their initial endoscopic tumour biopsy. The remainder (81.13%) showed preservation of staining for all MMRPs. There was complete agreement in MMR IHC status between the preoperative endoscopic biopsies and corresponding resection specimens in all cases (κ=1.000, P<0.000) with a sensitivity of 100% (95% CI 69.15 to 100) and specificity of 100% (95% CI 91.78 to 100) for detection of dMMR.ConclusionEndoscopic biopsies are a suitable source of tissue for MMR IHC analysis. This may provide a number of advantages to both patients and clinicians in the management of CRC.
How many people have been bitten by dogs? A cross-sectional survey of prevalence, incidence and factors associated with dog bites in a UK community
Authors: Westgarth Carri , Brooke Megan , Christley Robert M 
Published: February 2018

BackgroundDog bite studies are typically based on hospital records and may be biased towards bites requiring significant medical treatment. This study investigated true dog bite prevalence and incidence at a community-level and victim-related risk factors, in order to inform policy and prevention.MethodsA cross-sectional study of a community of 1280 households in Cheshire, UK, surveyed 694 respondents in 385 households. Data included dog ownership and bite history, demographics, health and personality (Ten Item Personality Inventory (TIPI) brief measure). Multivariable logistic regression modelled risk factors for having ever been bitten by a dog, accounting for clustering of individuals within households.ResultsA quarter of participants (24.78%, 95% CI 21.72 to 28.13) reported having ever been bitten by a dog during their lifetime, with only a third of bites described requiring further medical treatment and 0.6% hospital admission. Incidence of dog bites was 18.7 (11.0–31.8) per 1000 population per year. Males were 1.81 times more likely to have been bitten in their lifetime than females (95% CI 1.20 to 2.72, P=0.005). Current owners of multiple dogs were 3.3 times more likely (95% CI 1.13 to 9.69, P=0.03) to report having been bitten than people not currently owning a dog. Regarding all bites described, most commonly people were bitten by a dog that they had never met before the incident (54.7%). Individuals scoring higher in emotional stability had a lower risk of having ever been bitten (OR=0.77 for 1 point change in scale between 1 and 7, 95% CI 0.66 to 0.9, P=0.001).ConclusionThis study suggests that the real burden of dog bites is considerably larger than those estimated from hospital records. Further, many bites do not require medical treatment and hospital-based bite data are not representative of bites within the wider population. Victim personality requires further investigation and potential consideration in the design of bite prevention schemes.
