Menopause symptom prevalence in three post–COVID-19 syndrome clinics in England: A cross-sectional analysis

ObjectivesThere is an overlap between symptoms of perimenopause/menopause and post-COVID syndrome and there is a concern that some female patients referred to post-COVID syndrome clinics may have undiagnosed perimenopause/menopause. However, the prevalence of such symptoms in this population is unknown. MethodsCross-sectional analysis of 122 women's health questionnaires as part of a service improvement project in three National Health Service post-COVID syndrome clinics in England. The primary outcomes were prevalence of menopause symptoms and association between the total menopause symptom questionnaire (MSQ) score and the key predictors. ResultsAge group 40-54 years showed the highest prevalence of most individual symptoms and the highest mean total MSQ score (36.4; confidence interval [CI] 32.3-40.6), correlating clinically with the onset of perimenopause/menopause. Regression modeling shows a significant positive parabolic relationship between age and total MSQ score. Age group 40-54 years is associated with a 6.60-point higher (CI 1.31-11.9) total MSQ score than the age group 55-79 years; an increase of one index of multiple deprivation quintile is associated with a 2.85-point lower (CI −1.24 to −4.45) total MSQ score; presence of a gynecologic diagnosis is associated with a 6.31-point higher (CI 1.32-11.3) total MSQ score. A total of 51% of patients who menstruate reported menstrual disturbance with COVID-19 infection and 21% with COVID-19 vaccination. ConclusionsSymptoms possibly attributable to perimenopause and menopause were highly prevalent among female patients attending post-COVID syndrome clinics in Greater Manchester, England. Our findings provide key prevalence estimates and significant predictors of MSQ scores that are vital for future research, clinical practice, and policy.

Is Scotland Walking in the Right Direction? A Cross-Sectional Analysis of Trends in Walking by Socioeconomic Status.

Walking is a key target behavior for promoting population health. This paper charts the 30-year history of walking policy in Scotland. We assess whether population walking levels among adults in Scotland have changed in recent years and identify the characteristics of those least likely to report any walking. We pooled 9years (2012-2019 and 2021) of data from adult (≥16y) respondents of the Scottish Health Survey (n = 41,470). The outcomes of interest were the percentage reporting (1)any walking and (2)any walking with an average pace that is of at least moderate intensity. We also investigated the contribution of walking to total nonoccupational moderate to vigorous physical activity. We used linear and logistic regressions to test linear trends over time and to identify inequalities by age, sex, and the Scottish Index of Multiple Deprivation quintile. There was an increase in all measures of walking over the period 2012-2021; for example, the percentage reporting any walking increased by 7 percentage points (81.4%-88.4%). Inequalities still exist by age, sex, and the Scottish Index of Multiple Deprivation but have not grown over time. Inequalities by sex and age are most pronounced in the least affluent Scottish Index of Multiple Deprivation quintiles; less affluent older women are least likely to report any walking. Scotland appears to be walking in the right direction. Surveillance data support a positive trend after decades of policy and promotion efforts. The policies do not appear to be exacerbating existing inequalities, but narrowing them will require more concentrated efforts.

The effect of frailty on mortality and hospital admission in patients with benign pleural disease in Wales: a cohort study

Pleural disease is common, representing 5% of the acute medical workload, and its incidence is rising, partly due to the ageing population. Frailty is an important feature and little is known about disease progression in patients with frailty and pleural disease. We aimed to examine the effect of frailty on mortality and other relevant outcomes in patients diagnosed with pleural disease. In this cohort study in Wales, the national Secure Anonymised Information Linkage databank was used to identify a cohort of individuals diagnosed with non-malignant pleural disease between Jan 1, 2005, and March 1, 2023, who were not known to have left Wales. Frailty was assessed at diagnosis of pleural disease using an electronic Frailty Index. The primary outcome was time from diagnosis to all-cause mortality for all patients. Data were analysed using multilevel mixed-effects Cox proportional hazards regression adjusting for the prespecified covariates of age, sex, Welsh Index of Multiple Deprivation quintile, smoking status, comorbidity, and subtype of pleural disease. 54 566individuals were included in the final sample (median age 66years [IQR 47-77]; 26 477 [48·5%] were female and 28 089 [51·5%] were male). By the end of the study period, 25 698 (47·1%) participants had died, with a median follow-up of 1·0years (IQR 0·2-3·6). There was an association between frailty and all-cause mortality, which increased as frailty worsened. Compared with fit individuals, there was increasing mortality for those with mild frailty (adjusted hazard ratio 1·11 [95% CI 1·08-1·15]; p<0·0001), moderate frailty (1·25 [1·20-1·31]; p<0·0001), and severe frailty (1·36 [1·28-1·44]; p<0·0001). Independent of age and comorbidities, frailty status at diagnosis of pleural disease appeared to be useful as a prognostic indicator. Patients with moderate or severe frailty had a rapid decline in health. Future patients should be assessed for frailty at the time of diagnosis of pleural disease and might benefit from optimised care and advance care planning.

Paediatric open fractures presenting to a level 1 trauma centre: a 10 year epidemiological study.

The epidemiology of paediatric fractures has been previously described, however there is limited data available on open fractures in this population. The purpose of this study was to investigate trends, mechanism of injury (MOI) and severity of paediatric open fractures and undertake an epidemiological study. All children ≤ 16.0 years presenting with open fractures were identified between 01/04/2013 and 01/04/2023. Those with craniofacial, thoracic and distal phalangeal fractures were excluded. Incidence was calculated based on those presenting within the local geographical region. Social deprivation was measured using the Index of Multiple Deprivation (IMD). There were 208 open fractures with a median age of 11.0(q1 7.4-q3 13.4) years, and 153(74.6%) were in males. The MOIs were road traffic collisions 73(35.1%), sports/play 45(21.6%), fall > 2m 29(13.9%), simple fall 25(12.0%), crush 16(7.7%), bites 8(3.8%), assault 6(2.9%), and other 6(2.9%). Nineteen children (9.1%) presented with polytrauma. Gustilo-Anderson grade for long bone fractures were I-61(29.3%), II-24(11.5%), IIIa-36(17.3%), IIIb-30(14.4%) and IIIc-7(3.4%). There were 129 children presenting within the local geographical region providing an annual incidence of 8.0/100,000. Radius and ulna were the most frequently injured 49(38.0%) followed by tibia and fibula 44(34.1%). There were 69(53.5%) children presenting from an IMD quintile 1 with open fractures. Paediatric open fractures are commonly seen in the adolescent male and affect those who are from a more socially deprived background. These injuries account for 3.2% of fractures admitted to a MTC. Data suggests children principally sustain open fractures through two distinct injury patterns and ten-year trends suggests that there is a gradual decline in the annual incidence.

Impact of single round of low dose CT lung cancer screening on cause of mortality in different socio-economic groups: a post-hoc analysis of long-term follow-up of the UKLS trial

Lower socioeconomic status, as measured by the Index of Multiple Deprivation (IMD), is associated with higher rates of smoking-related disease mortality, and with poor uptake of cancer screening. Here we explore whether socioeconomic status impacts the effectiveness of a single round of low-dose-CT screening, or impacts other causes of death, in the UKLS LDCT screening trial. IMD quintiles were defined according to UK-wide data, with the deprived group defined as the lower two quintiles (Q1-2) and the less deprived as Q3-5. Follow-up data was obtained for lung cancer diagnosis (median follow-up 9.1 years) and cause of death (median follow-up 9.9 years). Outcomes were compared based on IMD group and trial arm (CT or control). More deprived quintiles were less likely to respond to the questionnaire, but this population was more likely to be selected for screening by the LLP risk model. Lower IMD quintiles benefitted from low-dose-CT screening in terms of lung cancer survival (HR 1.89, 95% CI 1.16-3.08) to the same extent as upper quintiles (HR 1.87, 95% CI 1.07-3.26). However, there was a bigger impact on deaths due to COPD and emphysema in more deprived quintiles. Whilst LDCT screening benefit for lung cancer was similar, significant impact on the rates of death from other smoking-related diseases, notably COPD and emphysema, was seen primarily in lower socioeconomic groups. Future research is required to confirm how lung cancer screening benefits other disease outcomes.

BackgroundReductions in local government funding implemented in 2010 due to austerity policies have been associated with worsening socioeconomic inequalities in mortality. Less is known about the relationship of these reductions...

Socioeconomic inequalities in accumulation of multimorbidity in England from 2019 to 2049: a microsimulation projection study

There are socioeconomic inequalities in the prevalence of multimorbidity and its accumulation across the life course. Estimates of multimorbidity prevalence in English primary care increased by more than two-thirds from 2004 to 2019. We developed a microsimulation model to quantify current and projected multimorbidity inequalities in the English adult population. We used primary care data for adults in England from the Clinical Practice Research Datalink Aurum database between 2004 and 2019, linked to the 2015 English Index of Multiple Deprivation (IMD), to model time individuals spent in four health states (healthy, one chronic condition, basic multimorbidity [two or more chronic conditions], and complex multimorbidity [three or more chronic conditions affecting three or more body systems]) by sex, age, IMD quintile, birth cohort, and region. We applied these transition times in a stochastic dynamic continuous-time microsimulation model to Office for National Statistics population estimates for adults aged 30-90 years. We calculated projected prevalence and cumulative incident cases from 2019 to 2049 by IMD quintile, age group (younger than 65 years vs 65 years and older), and years to be lived without multimorbidity at age 30 years. Under the assumption that all chronic conditions were lifelong, and that once diagnosed there was no recovery, we projected prevalence of multimorbidity (basic or complex) increases by 34% from 53·8% in 2019 to 71·9% (95% uncertainty interval 71·8-72·0) in 2049. This rise equates to an 84% increase in the number of people with multimorbidity: from 19·2 million in 2019 to 35·3 million in 2049 (35·3 million to 35·4 million). This projected increase is greatest in the most deprived quintile, with an excess 1·07 million (1·04 million to 1·10 million) cumulative incident basic multimorbidity cases and 0·70 million (0·67 million to 0·74 million) complex multimorbidity cases over and above the projected cases for the least deprived quintile, largely driven by inequalities in those younger than 65 years. The median expected number of years to be lived without multimorbidity at age 30 years in 2019 is 15·12 years (14·62-16·01) in the least deprived IMD quintile and 12·15 years (11·61-12·60) in the most deprived IMD quintile. The number of people living with multimorbidity will probably increase substantially in the next 30 years, a continuation of past observed increases partly driven by changing population size and age structure. Inequalities in the multimorbidity burden increase at each stage of disease accumulation, and are projected to widen, particularly among the working-age population. Substantial action is needed now to address population health and to prepare health-care and social-care systems for coming decades.

Neighborhood Deprivation and Changes in Oral Health in Older Age: A Longitudinal Population-Based Study

The aim of this study was to examine the extent to which neighborhood-level socioeconomic factors (objective and perceived) are associated with poor oral health in older adults over time, independent of individual socioeconomic position. Data for this cross-sectional and longitudinal observation study came from a socially and geographically representative cohort of men aged 71 to 92 y in 2010–12 (n = 1,622), drawn from British general practices, which was followed up in 2018–19 (aged 78–98 y; N = 667). Dental measures at both times included number of teeth, periodontal pocket depth, self-rated oral health, and dry mouth. Neighborhood deprivation was based on Index of Multiple Deprivation (IMD) and a cumulative index measuring perceptions about local environment. Individual-level socioeconomic position was based on longest-held occupation. Multilevel and multivariate logistic regressions, adjusted for relevant sociodemographic, behavioral, and health-related factors, were performed to examine the relationships of dental measures with IMD and perceived neighborhood quality index, respectively. Cross-sectionally, risks of tooth loss, periodontal pockets, and dry mouth increased from IMD quintiles 1 to 5 (least to most deprived); odds ratios (ORs) for quintile 5 were 2.22 (95% confidence interval [CI], 1.41–3.51), 2.82 (95% CI, 1.72–4.64), and 1.51 (95% CI, 1.08–2.09), respectively, after adjusting for sociodemographic, behavioral, and health-related factors. Risks of increased pocket depth and dry mouth were significantly greater in quintile 5 (highest problems) of perceived neighborhood quality index compared to quintile 1. Over the 8-y follow-up, deterioration of dentition (tooth loss) was significantly higher in the most deprived IMD quintiles after full adjustment (OR for quintile 5 = 2.32; 95% CI, 1.09–4.89). Deterioration of dentition and dry mouth were significantly greater in quintile 5 of perceived neighborhood quality index. Neighborhood-level factors were associated with poor oral health in older age, both cross-sectionally and longitudinally, particularly with tooth loss, and dry mouth, independent of individual-level socioeconomic position.

The role of the multiple Index of deprivation in predicting mental health outcomes after the COVID-19 pandemic in adolescents: a cross-sectional study

BackgroundThe number of children and young people (CYP) diagnosed with mental health problems has increased over the past decade. The COVID-19 pandemic also has accelerated this increase, raising significant concerns about adolescent emotional wellbeing. Research suggests that adolescents who live in more deprived areas are more likely to experience poor emotional wellbeing. Children in the northwest of England are among those with the poorest outcomes in the UK. We aimed to investigate the association between deprivation and mental health outcomes from 2019 to 2022. The aim was to support local authorities with targeted provision of public health services as well as predicting service need for 2022 onwards. MethodsIn this cross-sectional study, we analysed routinely collected Schools Health Needs Assessment (SHNA) data. The School Health Needs Assessment dataset contained 32 676 responses from Year 6 (ages 10–11 years) and Year 9 (ages 13–14 years) who completed the annual survey in 2019–22. The questionnaire was offered to all mainstream schools, delivered by the public health school nursing service. Index of multiple deprivation (IMD) data were provided for household postcodes. Data were analysed using IBM SPSS. Factor analysis created a composite emotional wellbeing scale (EWS) and estimates generated by school year (Years 6 and 9) and three academic years (2019–22). We calculated correlations between IMD and EWS overall and within school and academic year samples. FindingsThe final total sample across the three consecutive survey years and the two school years was 32 659. The sample consisted of 15 932 (49%) female students and 5066 (16%) students who registered at school as from an ethnic minority. Of the total sample, 9209 (28%) lived in a postcode in the most deprived IMD quintile in England. There was an overall decrease in EWS from Year 6 to Year 9 and from 2019 to 2022. The Year 6 students in 2022 reported mean levels of EWS equivalent to Year 9 students in 2019 indicating a shift toward poorer mental health in younger children. The correlational analyses showed no significant associations between IMD and EWS scores within the school or academic year cohorts. A follow-up analysis of children in receipt or not in receipt of free school meals also showed no significant association with EWS scores. InterpretationFindings showed that the emotional wellbeing of children and young people in the northwest of England has deteriorated since 2019, with greatest changes observed in the younger cohort of children in Year 6. This was not explained by postcode-based indices of multiple deprivation. Although it is recognised that deprivation is both a cause and a result of poor mental health, policy decisions on service provision for children and young people should not be based solely on IMD or receipt of free school meals. A rapid response is required to address the decline in emotional wellbeing currently observed in younger children of the northwest of England. FundingNone.

Assessment of the association between ambient air pollution and stillbirth in the UK: Results from a secondary analysis of the MiNESS case-control study.

We examined whether the risk of stillbirth was related to ambient air pollution in a UK population. Prospective case-control study. Forty-one maternity units in the UK. Women who had a stillbirth ≥28 weeks' gestation (n = 238) and women with an ongoing pregnancy at the time of interview (n = 597). Secondary analysis of data from the Midlands and North of England Stillbirth case-control study only including participants domiciled within 20 km of fixed air pollution monitoring stations. Pollution exposure was calculated using pollution climate modelling data for NO2 , NOx and PM2.5 . The association between air pollution exposure and stillbirth risk was assessed using multivariable logistic regression adjusting for household income, maternal body mass index (BMI), maternal smoking, Index of Multiple Deprivation quintile and household smoking and parity. Stillbirth. There was no association with whole pregnancy ambient air pollution exposure and stillbirth risk, but there was an association with preconceptual NO2 exposure (adjusted odds ratio [aOR] 1.06, 95% CI 1.01-1.08 per microg/m3 ). Risk of stillbirth was associated with maternal smoking (aOR 2.54, 95% CI 1.38-4.71), nulliparity (aOR 2.16, 95% CI 1.55-3.00), maternal BMI (aOR 1.05, 95% CI 1.01-1.08) and placental abnormalities (aOR 4.07, 95% CI 2.57-6.43). Levels of ambient air pollution exposure during pregnancy in the UK, all of were beneath recommended thresholds, are not associated with an increased risk of stillbirth. Periconceptual exposure to NO2 may be associated with increased risk but further work is required to investigate this association.

Validation of a dynamic method of measuring households and populations from primary care Electronic Health Records: Cross-sectional comparison with Office for National Statistics Census 2021 estimates

ObjectivesWe have developed a dynamic method for identifying household members from Electronic Health Records (EHR). We compared the 2021 Census estimates of household number and demography with similar estimates derived from primary care EHRs on the Census date using primary care EHRs for the population of north east London (NEL).&#x0D; MethodWe included 2,115,017 patients registered with a general practitioner on the 2021 Census date in NEL and assigned households from encrypted Unique Property Reference Numbers. We compared household number and size by Local Authority (LA), Middle Layer Super Output Area (MSOA) and area’s Index of Multiple Deprivation quintiles (IMDq) to Office for National Statistics (ONS) 2021 Census estimates and by LA to ONS Admin Based Housing Stock (ABHS) 2020 estimates. We assessed differences in EHR and Census 2021 populations by sex, age, LA, MSOA and IMDq. Sensitivity analyses will exclude those without a recent recorded clinical encounter.&#x0D; ResultsEHR population estimates (2,115,017) were 116,346 (5.8%) higher than Census estimates (1,998,671), higher among men (9.2%) than women (2.5%) in almost all age groups, especially men aged 30-50 years and higher in the most (8.7%), than in the least (2.5%) deprived IMDq. EHR household estimates (660,789) were 68,047 (9.3%) lower than Census estimates (728,836), and 19,719 (3.1%) higher than ABHS occupied addresses (641,070). EHR household size estimates were 15.6%, 29.2%,12.5% and 8.4% lower for household sizes 1,2 3 and 4, and 13.3%, 42.1%, 82.1% and 195.8% higher for household sizes 5, 6,7 and 8 respectively when compared to Census estimates. EHR population and household estimates were respectively 5-10% higher and 5-11% lower for almost all NEL local authorities.&#x0D; ConclusionEHR- and Census-derived population and household estimates differ, mainly in the prevalence of larger households. While data were extracted on the same date, person-level validation was not possible. Differences may reflect deregistration delay in EHR when changing residence. Analyses based on clinical encounters recency may identify registered patients who are no longer residents.

Colorectal cancer incidence trends by tumour location among adults of screening-age in England: a population-based study.

Proximal and distal colorectal cancers (CRCs) exhibit different clinical, molecular and biological patterns. The aim of this study was to determine temporal trends in the age-standardized incidence rates (ASIRs) of proximal and distal CRC following the introduction of the English Bowel Cancer Screening Programme (BCSP) in 2006. The National Cancer Registration and Analysis Service database was used to identify incident cases of CRC among adults of screening age (60-74 years) between 2001 and 2017. ASIRs were calculated using the European Standard Population 2013 and incidence trends analysed by anatomical subsite (proximal, caecum to descending colon; distal, sigmoid to rectum), sex and Index of Multiple Deprivation (IMD) quintile using Joinpoint regression software. Between 2001 and 2017, 541 515 incident cases of CRC were diagnosed [236 167 proximal (43.6%) and 305 348 distal (56.4%)]. A marginal reduction in the proximal ASIR was noted from 2008 [annual percentage change (APC) -1.4% (95% CI -2.0% to -0.9%)] compared with a greater reduction in distal ASIR from 2011 to 2014 [APC -6.6% (95% CI -11.5% to -1.5%)] which plateaued thereafter [APC -0.5% (95% CI -3.2% to 2.2%)]. Incidence rates decreased more rapidly in men than women. Adults in IMD quintiles 4-5 experienced the greatest reduction in distal tumours [APC -3.5% (95% CI -4.3% to -2.7%)]. Following the introduction of the English BCSP, the incidence of CRC has subsequently reduced among adults of screening age, with this trend being most pronounced in distal tumours and in men. There is also evidence of a reduction in the deprivation gap for distal tumour incidence. Strategies to improve the detection of proximal tumours are warranted.

Non-fatal overdose risk associated with prescribing opioid agonists concurrently with other medication: Cohort study conducted using linked primary care, secondary care and mortality records.

An apparently protective effect of opioid agonist treatment (OAT) on all-cause and cause-specific mortality risk has been widely reported. Non-fatal overdose (NFO) often precedes subsequent drug-poisoning deaths. We hypothesized that benzodiazepines, gabapentinoids, antipsychotics, antidepressants, Z-drugs or opioids increase the NFO risk when co-prescribed with OAT. We conducted a cohort study using the Clinical Practice Research Datalink GOLD and Aurum databases. The cohort was linked to Hospital Episode Statistics admitted patient care data (HES-APC), neighbourhood- and practice-level Index of Multiple Deprivation quintiles and mortality records from the Office for National Statistics. Primary care in England. We studied patients with opioid use disorder, aged 18-64 years, who were prescribed OAT (15155 methadone and 5743 buprenorphine recipients) between Jan 1, 1998, and Dec 31, 2017. The main outcome examined was NFO risk during co-prescription of OAT with benzodiazepines, antipsychotics, gabapentinoids, antidepressants, Z-drugs or opioids. Overdose was defined according to International Classification of Diseases codes from the HES-APC data set. Negative binomial regression models were used to estimate weighted rate ratios (wRR) for NFO during co-prescription of OAT and benzodiazepines, antipsychotics, gabapentinoids, antidepressants, Z-drugs or opioids with periods of exclusive OAT usage. Among 20 898 patients observed over 83 856 person-years, we found an elevated overdose risk that resulted in hospital admission during co-prescription of OAT with benzodiazepines [wRR: 1.45; 95% confidence interval (CI) = 1.26-1.67], gabapentinoids (wRR = 2.22; 95% CI = 1.77-2.79), Z-drugs (wRR = 1.60; 95% CI = 1.31-1.96), antipsychotics (wRR = 1.85; 95% CI = 1.53-2.25) and opioids (wRR = 1.28; 95% CI = 1.02-1.60). The risk ratio for antidepressant co-prescriptions was below unity (wRR = 0.90; 95% CI = 0.79-1.02) but this result was not statistically significant. Elevated risk of non-fatal overdose among opioid agonist treatment recipients is associated with concurrent use of medication prescribed for other reasons.

Duration of protection of ancestral-strain monovalent vaccines and effectiveness of bivalent BA.1 boosters against COVID-19 hospitalisation in England: a test-negative case-control study

Bivalent BA.1 booster vaccines were offered to adults aged 50 years or older and clinically vulnerable people as part of the 2022 autumn COVID-19 booster vaccination programme in England. Previously, all adults in England had been offered a primary course consisting of two doses of either ChAdOx1-S or monovalent mRNA vaccine and an mRNA monovalent booster vaccine. We aimed to estimate the long-term duration of protection provided by monovalent COVID-19 vaccines, and the incremental vaccine effectiveness of bivalent BA.1 boosters. In this test-negative case-control study, cases of COVID-19 and controls aged 18 years or older were identified from national data for PCR tests done in hospital settings in England. Our analysis was restricted to people with acute respiratory infections coded in the primary diagnosis field. Data for vaccination status were extracted from the English national vaccine register and linked to COVID-19 testing data. Between June 13 and Dec 25, 2022, we estimated the vaccine effectiveness against hospitalisation of two or three or more doses of monovalent COVID-19 vaccines compared with being unvaccinated, stratified by age (18-64 years vs ≥65 years). Between Sept 5, 2022, and Feb 5, 2023, we estimated the incremental vaccine effectiveness (ie, in addition to the protection from earlier vaccines) of receiving a bivalent BA.1 booster vaccine in addition to at least two doses of a monovalent vaccine (when the last dose was at least 6 months ago) among people aged 50 years or older. Analyses were adjusted for week of test, gender, age, COVID-19 risk group, residing in a care home, being a health or social care worker, Index of Multiple Deprivation quintile, ethnicity, and recent COVID-19 positivity. Our analysis of monovalent COVID-19 vaccines included 19 841 cases and 43 410 controls. Absolute vaccine effectiveness against hospitalisation among people who had received at least three doses plateaued from 6 months after the last dose at around 50% in those aged 65 years or older and at around 30% in those aged 18-64 years. Our analyses of the effectiveness of bivalent BA.1 boosters included data for 9954 cases and 39 108 controls aged 50 years or older. Incremental vaccine effectiveness peaked at 53·0% (95% CI 47·9-57·5) 2-4 weeks after administration, before waning to 35·9% (31·4-40·1) after 10 or more weeks. Our study provides evidence that monovalent COVID-19 vaccines offer moderate long-term protection against hospitalisation in people aged 65 years or older and that the bivalent BA.1 booster vaccines were effective in preventing hospitalisation among people aged 50 years or older at a time when omicron lineages were circulating in England. None.

P-444 The use of socioeconomic deprivation as an explanation of variation in IVF success rates between clinics

Abstract Study question Can differences in the live birth rate (LBR) between clinics with similar standard operating procedures (SOPs) be explained by variations in socioeconomic deprivation? Summary answer Socioeconomic deprivation does not appear to explain differences in LBR between clinics with similar SOPs in this cohort What is known already IVF success rates vary markedly between clinics. Numerous factors determine whether an IVF cycle is likely to be successful. It has been suggested that more socioeconomically deprived women are significantly less likely to achieve a live birth per cycle than less deprived women. In the UK, there is considerable variation in the levels of socioeconomic deprivation between different cities. Study design, size, duration We undertook a multi-center, retrospective review of prospectively collected data. We included all women undergoing their first IVF/ICSI cycle between January 2016 and December 2020 in eight different clinics belonging to the same IVF group. Clinics were located across England: three were situated in ‘very deprived’ cities, two in ‘predominantly affluent’ cities and the remaining cities were ‘neither very deprived nor very affluent’ i.e. their distribution was not skewed. Participants/materials, setting, methods We included all women undergoing their first IVF/ICSI cycle involving transfer of a single, fresh embryo. SOPs for medical and laboratory aspects of treatment were similar across all eight clinics. Socioeconomic deprivation was assessed using the Index of Multiple Deprivation (IMD) determined by the residential postcode of each woman undergoing treatment. Patients were categorized into quintiles according to IMD score. Live birth rates across IMD quintiles were calculated. Statistical analysis was performed using SPSS 22. Main results and the role of chance In total, across the 8 clinics, 17171 women underwent an IVF/ICSI cycle. The LBR ranged from 17.9 - 35.7% (p &amp;lt; 0.001) with both upper and lower extremes in clinics in cities classified as ‘neither very deprived nor very affluent’. The overall LBR ranged from 23.7-26.0% across the IMD quintiles. This difference was neither linear nor statistically significant. Similar trends were noted whether the treatment was NHS (n = 4992) or self-funded (n = 12179). The proportion of women in each IMD quintile varied significantly (p &amp;lt; 0.001) across the different clinics: in the most deprived quintile this ranged from 3.2 - 22.8% and in the least deprived quintile this ranged from 19.1 - 30.8%. The LBR in each IMD quintile also varied significantly (p &amp;lt; 0.001) across the different clinics. The LBR in the most deprived quintile ranged from 7.1 - 46.1% and in the least deprived quintile ranged from 19.4 - 22.9%. Limitations, reasons for caution Our results require caution as the distribution of deprivation amongst women undergoing IVF was not representative of the cities in which clinics were located with a skew towards greater affluence seen. Further unknown variables appear responsible for the significant variation in LBRs between clinics rather than IMD categorization alone. Wider implications of the findings The distribution of deprivation amongst women undergoing IVF was not representative of the cities in which clinics were located. Whilst not unexpected due to the cost of IVF, ethical questions regarding access to fertility care are highlighted and efforts to promote inclusion should be prioritized.

Delirium in hip fracture patients admitted from home during the COVID-19 pandemic is associated with higher mortality, longer total length of stay, need for post-acute inpatient rehabilitation, and readmission to acute services.

Delirium is associated with adverse outcomes following hip fracture, but the prevalence and significance of delirium for the prognosis and ongoing rehabilitation needs of patients admitted from home is less well studied. Here, we analyzed relationships between delirium in patients admitted from home with 1) mortality; 2) total length of hospital stay; 3) need for post-acute inpatient rehabilitation; and 4) hospital readmission within 180 days. This observational study used routine clinical data in a consecutive sample of hip fracture patients aged ≥ 50 years admitted to a single large trauma centre during the COVID-19 pandemic between 1 March 2020 and 30 November 2021. Delirium was prospectively assessed as part of routine care by the 4 A's Test (4AT), with most assessments performed in the emergency department. Associations were determined using logistic regression adjusted for age, sex, Scottish Index of Multiple Deprivation quintile, COVID-19 infection within 30 days, and American Society of Anesthesiologists grade. A total of 1,821 patients were admitted, with 1,383 (mean age 79.5 years; 72.1% female) directly from home. Overall, 87 patients (4.8%) were excluded due to missing 4AT scores. Delirium prevalence in the whole cohort was 26.5% (460/1,734): 14.1% (189/1,340) in the subgroup of patients admitted from home, and 68.8% (271/394) in the remaining patients (comprising care home residents and inpatients when fracture occurred). In patients admitted from home, delirium was associated with a 20-day longer total length of stay (p < 0.001). In multivariable analyses, delirium was associated with higher mortality at 180 days (odds ratio (OR) 1.69 (95% confidence interval (CI) 1.13 to 2.54); p = 0.013), requirement for post-acute inpatient rehabilitation (OR 2.80 (95% CI 1.97 to 3.96); p < 0.001), and readmission to hospital within 180 days (OR 1.79 (95% CI 1.02 to 3.15); p = 0.041). Delirium affects one in seven patients with a hip fracture admitted directly from home, and is associated with adverse outcomes in these patients. Delirium assessment and effective management should be a mandatory part of standard hip fracture care.

#4727 FLOZINATION: A ROLLING QUALITY IMPROVEMENT PROGRAMME

Abstract Background and Aims Sodium glucose linked transporter-2 inhibitors (SGLT2i) reduce renal and cardiovascular end points in people with chronic kidney disease (CKD), both with and without diabetes. Despite exciting data from the CREDENCE and DAPA-CKD trials, implementation of new evidence to every day clinical practice can be challenging. We present the results of a rolling quality improvement project regarding SGLT2i prescription. The aim of the project was to support clinicians in the evidence based prescribing of SGLT2i for CKD. Method Three renal units who share a single electronic clinical database agreed a joint protocol and staged implementation programme. These tertiary referral renal units cover a population of around 2.3 million people. The important timeline regarding SGLT2i licensing and interventions is shown in Figure 1. Interventions were as follows: 1. Identification of patients meeting the licensing criteria for prescription of canagliflozin for CKD with diabetes. 2. Addition of an alert to the electronic patient record. 3. SGLT2i protocol developed and advertised via poster in outpatient clinic sites. 4. Evaluation of clinician attitude to prescribing. 5. Measurement of number of patients meeting the licensing criteria for prescription of dapagliflozin for CKD with and without diabetes. Measurement of SGLT2i prescription was audited from the electronic record. Results In the first wave of the programme, 326 patients were identified as suitable under the initial licensing criteria for canagliflozin, and electronic alerts were added to the records of these patients. When measuring number of patients who may be suitable under the dapagliflozin licensing, there were 562 patients with diabetes and 5262 without diabetes. In a survey of clinician attitudes, 94% suggested they felt well equipped to prescribe SGLT2i. Prescribing of SGLT2i across time is shown in Figure 2. 1146 patients have been prescribed SGLT2i. Age was 64±13 years, and the majority were male (68%) with type 2 diabetes mellitus (61%). Most (73.6%) were treated with angiotensin converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB). More than half (54%) of patients live in areas with high levels of socio-economic deprivation (Scottish Index of Multiple Deprivation quintiles 1 or 2). Estimated glomerular filtration rate was 40.9±23.5ml/min/1.73 m2 and Kidney Failure Risk Equation (KFRE) 5 year risk of end stage kidney disease (ESKD) was 23.2±28.2%. In comparison with the general outpatient clinic population, the distribution of socioeconomic deprivation was similar, but a higher proportion were female (46%). Conclusion An iterative quality improvement project was designed around the evolving drug licensing of SGLT2i and capitalised on local strengths, including an effective and well used clinical electronic database shared across renal units. Clinicians have been supported in SGLT2i prescribing with highly visible clinical protocols, and electronic alerts to highlight candidate patients. A high level of SGLT2i prescribing has been achieved in a population at high risk of ESKD. Further interventions should focus on prescribing in groups where gaps have been identified – such as women and those without diabetes. Other units would be recommended to capitalise on existing strengths, exploit the use of clinical databases, and ensure protocols are inclusive and well-advertised in order to optimise evidence based treatment of CKD.

#3790 BASELINE BLOOD PRESSURE CONTROL IN THE NURTURE CKD COHORT STUDY

Abstract Background and Aims Blood pressure (BP) control is one of the most important therapeutic interventions in chronic kidney disease (CKD) and reduces cardiovascular morbidity, mortality and progression to end stage kidney disease. The optimal BP target for patients with CKD is debated, with several guidelines making different recommendations. This analysis of the UK multicentre NURTuRE CKD cohort study assessed achievement of BP targets and investigated associations with achieved BP. Method 2996 participants with CKD stages G3-4 or G1-2 plus albuminuria &amp;gt;30 mg/mmol were enrolled from 16 nephrology centres in the UK from 2017 to 2019. Medical history, demographic, biometric and laboratory samples were collected at baseline. BP was measured according to a standard operating procedure. Three measurements differing by &amp;lt;10% were recorded and the mean value used for analysis. BP control was assessed against the following guidelines: National Institute for Health and Clinical Excellence (NICE), Kidney Disease Improving Global Outcomes (KDIGO) 2012 and 2021 guidelines. Results 2992 participants had a baseline BP measurement and of these 59% were male, 53% were ≥65 years, 87% were of white ethnicity and 31% had diabetes. Median eGFR was 33.8 (24.0 to 46.6) ml/min/1.73m2. The mean systolic BP for the cohort was 139 ± 20 and diastolic 80 ± 12 mmHg. The characteristics of patients with a higher mean systolic BP included: ≥65 years, male sex, black ethnicity, diabetic, body mass index &amp;gt;30 kg/m2, a history of atherosclerotic cardiovascular disease, lower eGFR values and higher albuminuria category. Conversely, mean systolic BP was not associated with index of multiple deprivation quintiles, health literacy by the single-literacy item screener and smoking status. Achievement of BP targets is shown in Table 1. Of 2723 with centrally calculated urine albumin creatinine ratio (ACR) and BP data available, only 1036 participants (38.0%) met the NICE guideline recommended BP. For the KDIGO 2012 guideline, 794 participants (29.2%) achieved recommended BP control. For KDIGO 2021, only 420 participants (15.4%) met the standard of systolic BP &amp;lt;120mmHg. For those in the highest risk albuminuria category (A3) only 143 (18.6%) and 96 (12.5%) of participants met the KDIGO BP recommendations for 2012 and 2021, respectively. Conclusion BP control in the NUTuRE-CKD cohort at baseline was suboptimal when compared to all three major guidelines. Subgroups at highest risk of adverse outcomes demonstrated poorer BP control. Given the importance of BP control in people with CKD, further research into BP management approaches and barriers to achieving optimal control is required. Priority should be given to developing a patient-centred approach to reduce BP more effectively.
