Trends and geographical variations in outpatient antimicrobial consumption in Ireland in relation to socio-economic deprivation.

Background: Different factors have been associated with changes in antimicrobial consumption rates in Ireland, however the relationship between socio-economic deprivation and antimicrobial consumption has not been explored. The presented ecological analysis explores the temporal and geographical variation in outpatient antimicrobial consumption and socio-economic deprivation in Ireland from January 2015 to March 2022. Method: Deprivation index (DI) was used as a socio-economic proxy. A multilevel mixed model was applied to explore temporal variation and analyse the longitudinal antimicrobial consumption (DID) in relation to DI. Furthermore, maps were generated based on antimicrobial consumption rates, and spatial autocorrelation analyses were carried out to study geographical variation in antimicrobial consumption rates. Results: The antimicrobial consumption rates per month varied from 26.2 DID (January 2015) to 22.1 DID (March 2022) showing an overall reduction of 16 %. Overall, total antimicrobial consumption in the multilevel model showed a consistent correlation with higher DI score (6.6 (95%CI 3.9 to 9.3)), and winter season (3.6 (95%CI 3.2 to 3.9)). In contrast, before COVID-19 showed significant lower antimicrobial consumption rates compared to during COVID-19 (-4.0 (95%CI -4.7 to -3.23)). No consistent trends were observed for geographical variation between areas. Conclusion: Antimicrobial consumption rates decreased from 2015 to 2021 in Ireland. No geographical patterns were observed in antimicrobial consumption rates but associations between deprivation and antimicrobial consumption rates were observed.

Maternal social deprivation and preterm birth: The PreCARE cohort study.

BACKGROUND: Maternal exposure to unfavourable social conditions is associated with a higher rate of perinatal complications, such as placental vascular pathologies. A higher risk of preterm birth (PTB) has also been reported, and variations across studies and settings suggest that different patterns may be involved in this association. OBJECTIVE: To assess the association between maternal social deprivation and PTB (overall and by phenotype). METHODS: We analysed 9365 patients included in the PreCARE cohort study. Four dimensions (social isolation, insecure housing, no income from work and absence of standard health insurance) defined maternal social deprivation (exposure). They were considered separately and combined into a social deprivation index (SDI). The associations between social deprivation and PTB <37 weeks (primary outcome) were analysed with univariable and multivariable log-binomial models (adjusted for maternal age, parity, education level and birthplace). Then we used multinomial analysis to examine the association with preterm birth phenotypes (secondary outcome): spontaneous labour, preterm prelabour rupture of membranes (PPROM) and placental vascular pathologies. RESULTS: In all, 66.3%, 17.8%, 8.9% and 7.0% of patients had an SDI of 0, 1, 2 and 3, respectively. Social isolation affected 4.5% of the patients, insecure housing 15.5%, no income from work 15.6% and no standard health insurance 22.4%. Preterm birth complicated 7.0% of pregnancies (39.8% spontaneous labour, 28.3% PPROM, 21.8% placental vascular pathologies and 10.1% other phenotypes). Neither the univariable nor multivariable analyses found any association between social deprivation and the risk of preterm birth overall (SDI 1 versus 0: aRR 1.02, 95% confidence interval [CI] 0.83, 1.26; 2 versus 0: aRR 1.05, 95% CI 0.80, 1.38; 3 versus 0: aRR 0.92, 95% CI 0.66, 1.29) or its different phenotypes. CONCLUSIONS: In the French PreCARE cohort, we observed no association between markers of social deprivation and the risk of preterm birth, regardless of phenotype.

Disparities in Emergency Medical Services Use, Prehospital Notification, and Symptom Onset to Arrival in Patients With Acute Stroke.

BACKGROUND: Disparities in time to hospital presentation and prehospital stroke care may be important drivers in inequities in acute stroke treatment rates, functional outcomes, and mortality. It is unknown how patient-level factors, such as race and ethnicity and county-level socioeconomic status, affect these aspects of prehospital stroke care. METHODS: Cross-sectional study of patients with ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage in the Get With the Guidelines-Stroke registry, presenting from July 2015 to December 2019, with symptom onset <24 hours. Multivariable logistic regression and quantile regression were used to investigate the outcomes of interest: emergency medical services (EMS) transport (versus private vehicle), EMS prehospital notification (versus no prehospital notification), and stroke symptom onset to time of arrival at the emergency department. Prespecified covariates included patient-level, hospital-level, and county-level characteristics. RESULTS: The inclusion criteria was met by the 606 369 patients. Of the patients, 51.2% were men and 69.9% White, with a median National Institutes of Health Stroke Severity of 4 (IQR, 2-10), and median social deprivation index (SDI) of 51 (IQR, 27-75). Median symptom onset to arrival time was 176 minutes (IQR, 64-565). Black race was significantly associated with prolonged symptom onset to emergency department arrival time (+28.21 minutes [95% CI, 25.59-30.84]), and decreased odds of EMS prehospital notification (OR, 0.80 [95% CI, 0.78-0.82]). SDI was not associated with differences in EMS use but was associated with lower odds of EMS prehospital notification (upper SDI tercile versus lowest, OR, 0.79 [95% CI, 0.78-0.81]). SDI was also significantly associated with stroke symptom onset to emergency department arrival time (upper SDI tercile versus lowest +2.56 minutes [95% CI, 0.58-4.53]). CONCLUSIONS: In this national cross-sectional study, Black race was associated with prolonged onset to time of arrival intervals and significantly decreased odds of EMS prehospital notification, despite similar use of EMS transport. Greater county-level deprivation was also associated with reduced odds of EMS prehospital notification and slightly prolonged stroke symptom onset to emergency department arrival time. Efforts to reduce place-based disparities in stroke care must address significant inequities in prehospital care of acute stroke and continue to address health inequities associated with race and ethnicity.

Digital Exclusion, Social Deprivation, and Clinical Outcomes of Patients Undergoing Hyperacuity Home Monitoring.

INTRODUCTION: Digital exclusion is a growing challenge when deploying digital patient care pathways and a potential barrier to widespread implementation, especially in the field of smartphone-based self-monitoring of vision. This retrospective case series seeks to examine the characteristics of individuals who adhere to a smartphone home monitoring programme using the Alleye app for retinal disease, with a focus on digital exclusion, social deprivation and clinical outcomes. METHODS: We conducted a retrospective analysis of 89 patients with retinal pathologies including diabetic retinopathy and retinal vein occlusions at Moorfields Eye Hospital participating in an Alleye home monitoring programme between April 2020 and November 2022. Postcodes were used to determine the Digital Exclusion Risk Index (DERI) and the Index of Multiple Deprivation (IMD) rebased for London. Clinical information from the electronic patient record and Alleye app usage data were extracted for each patient. Associations between the DERI/IMD, clinical parameters and app use were examined using multivariable regression models. RESULTS: Mean DERI was 2.56 (standard deviation [SD] = 0.36), IMD was 6.25 (SD = 2.79), visual acuity (VA) in the better eye at study entry was 83.28 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (SD = 7.92), and mean follow-up was 344.46 days (SD = 260.13). During the observation period, 36% received an intravitreal injection (IVI) and VA fell by at least ten letters in approximately one in four patients. In 87.5% of patients requiring IVI, the use of the app increased. We found no association between clinical parameters and programme adherence for DERI or IMD. CONCLUSIONS: We found no association between high digital exclusion risk and high social deprivation with monitoring adherence to smartphone-based self-monitoring of vision, contrary to the currently available evidence. This suggests that smartphone-based self-monitoring of vision is accessible to population groups of varying digital exclusion and social deprivation risk, and can be safely employed to monitor clinical progression.

Equity in the provision of helicopter emergency medical services in the United Kingdom: a geospatial analysis using indices of multiple deprivation.

BACKGROUND: Helicopter Emergency Medical Services (HEMS) in the United Kingdom (UK) are provided in a mixed funding model, with the majority of services funded by charities alongside a small number of government-funded operations. More socially-deprived communities are known to have greater need for critical care, such as that provided by HEMS in the UK. Equity of access is an important pillar of medical care, describing how resource should be allocated on the basis of need; a concept that is particularly relevant to resource-intensive services such as HEMS. However, the Inverse Care Law describes the tendency of healthcare provision to vary inversely with population need, where healthcare resource does not meet the expected needs in areas of higher deprivation. It is not known to what extent the Inverse Care Law applies to HEMS in the UK. METHODS: Modelled service areas were created with each small unit geography locus in the UK assigned to its closest HEMS operational base. The total population, median decile on index of multiple deprivation, and geographic area for each modelled service area was determined from the most recently available national statistics. Linear regression was used to determine the association between social deprivation, geographic area, and total population served for each modelled service area. RESULTS: The provision of HEMS in the UK varied inversely to expected population need; with HEMS operations in more affluent areas serving smaller populations. The model estimated that population decreases by 18% (95% confidence interval 1-32%) for each more affluent point in median decile of index of multiple deprivation. There was no significant association between geographic area and total population served. CONCLUSION: The provision of HEMS in the UK is consistent with the Inverse Care Law. HEMS operations in more deprived areas serve larger populations, thus providing a healthcare resource inversely proportional with the expected needs of these communities. Funding structures may explain this variation as charities are more highly concentrated in more affluent areas.

[Multidimensional Social Deprivation Impacts on Frailty in the Elderly: The Mediating Effect of Depression]. / 多维社会剥夺感对老年人衰弱的影响−抑郁的中介效应分析.

Objective: To investigate the mediating role of depression in the association between multidimensional social deprivation and frailty among the elderly. Methods: A total of 533 elderly individuals were enrolled from a district in Chengdu using a convenience sampling method. The participants responded to a questionnaire survey. Spearman rank correlation coefficient was employed to assess the correlations among social deprivation, depression, and frailty. MacKinnon's product-of-coefficients method was used to test the significance of the mediating effect of depression between social deprivation and frailty. Results: Among the participants, the average score for social deprivation among the participants was 48.9±7.1, the depression detection rate was 12.8%, and the frailty incidence rate was 8.4%. Social deprivation was positively correlated with frailty (r=0.212, P<0.001) and depression (r=0.399, P<0.001), while depression was positively correlated with frailty (r=0.248, P<0.001). The results of the mediation analysis showed that depression partially mediated the relationship between social deprivation and frailty (P<0.05), accounting for 64.95% of the mediation effect. Specifically, depression partially mediated the relationship between socio-economic status, comprehensive feeling, and frailty (P<0.05), accounting for 70.30% and 64.76% of the mediating effect, respectively. Depression fully mediated the relationship between family and social support, political and social participation dimensions, and frailty (P<0.05). Conclusion: Social deprivation can influence frailty in elderly people, with depression partially mediating this association.

A Comprehensive Insight into the Economic Profile of People Receiving Metabolic and Bariatric Surgery Use in France.

BACKGROUND: The use of metabolic and bariatric surgery (MBS) is not uniformly distributed within the population, even if it is governed by established guidelines. This disparity seems to be associated, among other factors, with the economic profile of people receiving this surgery. OBJECTIVES: We investigated the disparities in the use of MBS with respect to the socio-economic level in France based on socio-economic status (SES). MATERIALS AND METHODS: A descriptive observational study was conducted to compare the population of individuals with obesity who underwent MBS (MBS group) with individuals with obesity with no history of MBS (obese group). Data were extracted from the French National Hospital discharge database ("Programme De Médicalisation des Systèmes d'Information," PMSI). Socio-economic status (SES) was assessed through the French Deprivation Index (FDep). RESULTS: The use of MBS was significantly lower in patients having a higher SES compared to those having a lower one. There was no statistically significant difference in the use of MBS between individuals within the 4th and 5th SES quintiles compared to those in the 2nd and 3rd quintiles. No difference was found in the specific MBS procedures used depending on the SES. The obesity level was significantly lower in patients from the 1st and 3rd SES quintiles compared to the patients having a lower SES. CONCLUSION: Our study provides valuable insights into the complex interrelationships between the use of MBS, patients' SES, and obesity levels according to the FDep. These findings underscore the importance of developing targeted interventions to address disparities in the use of bariatric care.

Unveiling Hidden Disparities: Evaluating US Multiple Listing Practices in Lung Transplantation.

BACKGROUND: Multiple listing (ML) is a practice used to increase the potential for transplant but is controversial due to concerns that it disproportionately benefits patients with greater access to health care resources. RESEARCH QUESTION: Is there disparity in ML practices based on social deprivation in the United States and does ML lead to quicker time to transplant? STUDY DESIGN AND METHODS: A retrospective cohort study of adult (≥ 18 years of age) lung transplant candidates listed for transplant (2005-2018) was conducted. Exclusion criteria included heart only or heart and lung transplant and patients relisted during the observation period. Data were obtained from the United Network for Organ Sharing Standard Transplant Analysis and Research File. The first exposure of interest was the Social Deprivation Index with a primary outcome of ML status, to assess disparities between ML and single listing (SL) participants. The second exposure of interest was ML status with a primary outcome of time to transplant, to assess whether implementation of ML leads to quicker time to transplant. RESULTS: A total of 35,890 patients were included in the final analysis, of whom 791 (2.2%) were ML and 35,099 (97.8%) were SL. ML participants had lower median level of social deprivation (5 units, more often female: 60.0% vs 42.3%) and lower median lung allocation score (35.3 vs 37.3). ML patients were more likely to be transplanted than SL patients (OR, 1.42; 95% CI, 1.17-1.73), but there was a significantly quicker time to transplant only for those whom ML was early (within 6 months of initial listing) (subdistribution hazard ratio, 1.17; 95% CI, 1.04-1.32). INTERPRETATION: ML is an uncommon practice with disparities existing between ML and SL patients based on several factors including social deprivation. ML patients are more likely to be transplanted, but only if they have ML status early in their transplant candidacy. With changing allocation guidelines, it is yet to be seen how ML will change with the implementation of continuous distribution.

Early social isolation disrupts adult personality expression in group-living mites.

Animal personalities are characterized by intra-individual consistency and consistent inter-individual variability in behaviour across time and contexts. Personalities abound in animals, ranging from sea anemones to insects, arachnids, birds, fish and primates, yet the pathways mediating personality formation and expression remain elusive. Social conditions during the early postnatal period are known determinants of mean behavioural trait expressions later in life, but their relevance in shaping personality trajectories is unknown. Here, we investigated the consequences of early social isolation on adult personality expression in plant-inhabiting predatory mites Phytoseiulus persimilis. These mites are adapted to live in groups. We hypothesized that transient experience of social isolation early in life, that is, deprivation of any social contact during a sensitive window in the post-hatching phase, has enduring adverse effects on adult personality expression. Newly hatched mites were transiently reared in isolation or in groups and tested as adults for repeatability of various within-group behaviours, such as movement patterns and mutual interactions including sociability, defined as the propensity to associate and interact benignly with conspecifics, and activity patterns when alone. Groups composed of individuals with the same or different early-life experiences were repeatedly videotaped and individual behaviours were automatically analysed using AnimalTA. Social experiences early in life had persistent effects on mean behavioural traits as well as adult personality expression, as measured by intraclass correlation coefficients (indicating repeatability). On average, isolation-reared females moved at higher speeds, meandered less, kept greater distances from others and had fewer immediate neighbours than group-reared females. Group-reared females were highly repeatable in inter-individual distance, moving speed, meandering and area explored, whereas isolation-reared females were repeatable only in the number of immediate neighbours. Activity, quantified as the proportion of time spent moving within groups, was only repeatable in group-reared females, whereas activity, quantified as the proportion of time spent moving when alone, was only repeatable in females reared in isolation. Strikingly, also the early-life experiences of male mates influenced personality expression of mated females, with isolation-reared males boosting the repeatability of behavioural traits of group-reared females. Overall, our study provides evidence that a transient phase of social isolation during a critical period early in life has lasting effects that extend into adulthood, impairing adult personality expression. These effects should cascade upward, changing the phenotypic composition and diversity within populations.

Association between hospital procedure volume, socioeconomic status, comorbidities, and adverse events related to surgical abortion: A nationwide population-based cohort study.

BACKGROUND: Limited evidence exists on the influence of hospital procedure volume, socioeconomic status, and comorbidities on surgical abortion outcomes. OBJECTIVE: Our study aimed to assess the association between hospital procedure volume, individual and neighborhood deprivation, comorbidities, and abortion-related adverse events. STUDY DESIGN: A nationwide population-based cohort study of all women hospitalized for surgical abortion was conducted from January 1, 2018, to December 31, 2019 in France. Annual hospital procedure volume was categorized into four levels based on spline function visualization: very low (<80), low ([80-300[), high ([300-650[), and very high-volume (≥650) centers. The primary outcome was the occurrence of at least one surgical-related adverse event, including hemorrhage, retained products of conception, genital tract and pelvic infection, transfusion, fistulas and neighboring lesions, local hematoma, failure of abortion, admission to an intensive care unit or death. These events were monitored during the index stay and during a subsequent hospitalization up to 90 days. The secondary outcome encompassed general adverse events not directly linked to surgery. RESULTS: Of the 112,842 hospital stays, 4,951 (4.39%) had surgical-related adverse events and 256 (0.23%) had general adverse events. The multivariate analysis showed a volume-outcome relationship, with lower rates of surgical-related adverse events in very high-volume (2.25%, aOR=0.34, 95%CI [0.29-0.39], p<0.001), high-volume (4.24%, aOR=0.61, 95%CI [0.55-0.69], p<0.001), and low-volume (4.69%, aOR=0.81, 95%CI [0.75-0.88], p<0.001) when compared to very low-volume centers (6.65%). Individual socioeconomic status (aOR=1.69, 95%CI [1.47-1.94], p<0.001), neighborhood deprivation (aOR=1.31, 95% CI [1.22-1.39], p<0.001), and comorbidities (aOR=1.79, 95%CI [1.35-2.38], p<0.001) were associated with surgical-related adverse events. Conversely, the multivariate analysis of general adverse events did not reveal any volume-outcome relationship. CONCLUSION: The presence of a volume-outcome relationship underscores the need for enhanced safety standards in low-volume centers to ensure equity in women's safety during surgical abortions. However, our findings also highlight the complexity of this safety concern which involves multiple other factors including socioeconomic status and comorbidities that policymakers must consider.

The impact of socioeconomic deprivation on liver transplantation.

Despite global expansion, social disparities impact all phases of liver transplantation, from patient referral to post-transplant care. In pediatric populations, socioeconomic deprivation is associated with delayed referral, higher waitlist mortality, and reduced access to living donor transplantation. Children from socially deprived communities are twice as much less adherent to immunosuppression and have up to a 32% increased incidence of graft failure. Similarly, adult patients from deprived areas and racial minorities have a higher risk of not initiating the transplant evaluation, lower rates of waitlisting, and a 6% higher risk of not being transplanted. Social deprivation is racially segregated, and Black recipients have an increased risk of post-transplant mortality by up to 21%. The mechanisms linking social deprivation to inferior outcomes are not entirely elucidated, and powered studies are still lacking. We offer a review of the most recent evidence linking social deprivation and post-liver transplant outcomes in pediatric and adult populations, as well as a literature-derived theoretical background model for future research on this topic.

Do Social Deprivation and Surgical Volume Influence Outcomes Following Distal Radius Fracture Fixation?

BACKGROUND: Distal radius fractures account for nearly 25% of fractures in adults, with a trend toward operative fixation. The objective of this study was to assess the relationship between surgeon and hospital volume with complications following distal radius fixation. METHODS: A retrospective study was performed using the New York Statewide Planning and Research Cooperative System database from 2009 to 2015. Outpatient claims were identified for distal radius fractures and surgery. The facility and surgeon's identifier were used to calculate annual procedure volume. The risk for infection, carpal tunnel surgery, and revision/hardware removal was analyzed, and Social Deprivation Index (SDI) was linked to each patient. Patient demographics and rate of complications were compared across hospital and physician volume. RESULTS: A total of 14 748 patients were included, finding Federal and self-pay insurance associated with low-volume (LV) facility care and private insurance with high-volume (HV) facilities. The SDI for patients treated by LV surgeons and hospitals was significantly higher compared with HV providers. Low-volume facilities and surgeons had a higher 3-month risk of infection requiring reoperation. High-volume facilities were less likely to treat Hispanic patients, those with comorbidities, higher SDI, and with Federal or self-pay insurance. CONCLUSIONS: Patients treated by LV surgeons and facilities had a higher risk of infection requiring surgery within 3 months than those treated by HV providers. Low-volume facilities were more likely to treat patients who were Hispanic, Federally insured, and with comorbidities and higher SDI than HV facilities, increasing their risk for disadvantaged care. LEVEL OF EVIDENCE: Level III.

Description and Cross-Sectional Analyses of 25,880 Adults and Children in the UK National Registry of Rare Kidney Diseases Cohort.

Introduction: The National Registry of Rare Kidney Diseases (RaDaR) collects data from people living with rare kidney diseases across the UK, and is the world's largest, rare kidney disease registry. We present the clinical demographics and renal function of 25,880 prevalent patients and sought evidence of bias in recruitment to RaDaR. Methods: RaDaR is linked with the UK Renal Registry (UKRR, with which all UK patients receiving kidney replacement therapy [KRT] are registered). We assessed ethnicity and socioeconomic status in the following: (i) prevalent RaDaR patients receiving KRT compared with patients with eligible rare disease diagnoses receiving KRT in the UKRR, (ii) patients recruited to RaDaR compared with all eligible unrecruited patients at 2 renal centers, and (iii) the age-stratified ethnicity distribution of RaDaR patients with autosomal dominant polycystic kidney disease (ADPKD) was compared to that of the English census. Results: We found evidence of disparities in ethnicity and social deprivation in recruitment to RaDaR; however, these were not consistent across comparisons. Compared with either adults recruited to RaDaR or the English population, children recruited to RaDaR were more likely to be of Asian ethnicity (17.3% vs. 7.5%, P-value < 0.0001) and live in more socially deprived areas (30.3% vs. 17.3% in the most deprived Index of Multiple Deprivation (IMD) quintile, P-value < 0.0001). Conclusion: We observed no evidence of systematic biases in recruitment of patients into RaDaR; however, the data provide empirical evidence of negative economic and social consequences (across all ethnicities) experienced by families with children affected by rare kidney diseases.

Investigating mental healthcare inequalities associated with forced migration: promise and potential pitfalls of electronic health records.

There is a lack of data on mental health service utilisation and outcomes for people with experience of forced migration living in the UK. Details about migration experiences documented in free-text fields in electronic health records might be harnessed using novel data science methods; however, there are potential limitations and ethical concerns.

Social Support Buffers the Effect of Social Deprivation on Comorbidity Burden in Adults with Cancer.

BACKGROUND: Adults with cancer have higher rates of comorbidity compared to those without cancer, with excess burden in people from lower socioeconomic status (SES). Social deprivation, based on geographic indices, broadens the focus of SES to include the importance of "place" and its association with health. Further, social support is a modifiable resource found to have direct and indirect effects on health in adults with cancer, with less known about its impact on comorbidity. PURPOSE: We prospectively examined associations between social deprivation and comorbidity burden and the potential buffering role of social support. METHODS: Our longitudinal sample of 420 adults (Mage = 59.6, SD = 11.6; 75% Non-Hispanic White) diagnosed with cancer completed measures at baseline (~6 months post-diagnosis) and four subsequent 3-month intervals for 1 year. RESULTS: Adjusting for age, cancer type, and race/ethnicity, we found a statistically significant interaction between social support and the effect of social deprivation on comorbidity burden (ß = -0.11, p = 0.012), such that greater social support buffered the negative effect of social deprivation on comorbidity burden. CONCLUSION: Implementing routine screening for social deprivation in cancer care settings can help identify patients at risk of excess comorbidity burden. Clinician recognition of these findings could trigger a referral to social support resources for individuals high on social deprivation.

This study examines the complex interplay among neighborhood-level deprivation, social support, and comorbidity burden in adults diagnosed with cancer. We know that individuals with cancer often face health challenges, especially those from lower socioeconomic backgrounds. This research expands the scope beyond just income or education level to include the impact of "place" or social deprivation on health outcomes. The study followed 420 adults diagnosed with cancer over the course of a year, examining how social deprivation and social support influenced their comorbidity burden. Interestingly, findings suggest that social support can act as a buffer against the negative effects of social deprivation on comorbidity burden. These results highlight the importance of considering not only just medical treatment but also the social context in which patients live when managing cancer care. Identifying patients at risk of increased comorbidity burden due to social deprivation and providing them with appropriate social support resources could significantly improve their overall health.

Social deprivation and spatial clustering of childhood asthma in Australia.

BACKGROUND: Asthma is the most common chronic respiratory illness among children in Australia. While childhood asthma prevalence varies by region, little is known about variations at the small geographic area level. Identifying small geographic area variations in asthma is critical for highlighting hotspots for targeted interventions. This study aimed to investigate small area-level variation, spatial clustering, and sociodemographic risk factors associated with childhood asthma prevalence in Australia. METHODS: Data on self-reported (by parent/carer) asthma prevalence in children aged 0-14 years at statistical area level 2 (SA2, small geographic area) and selected sociodemographic features were extracted from the national Australian Household and Population Census 2021. A spatial cluster analysis was used to detect hotspots (i.e., areas and their neighbours with higher asthma prevalence than the entire study area average) of asthma prevalence. We also used a spatial Bayesian Poisson model to examine the relationship between sociodemographic features and asthma prevalence. All analyses were performed at the SA2 level. RESULTS: Data were analysed from 4,621,716 children aged 0-14 years from 2,321 SA2s across the whole country. Overall, children's asthma prevalence was 6.27%, ranging from 0 to 16.5%, with significant hotspots of asthma prevalence in areas of greater socioeconomic disadvantage. Socioeconomically disadvantaged areas had significantly higher asthma prevalence than advantaged areas (prevalence ratio [PR] = 1.10, 95% credible interval [CrI] 1.06-1.14). Higher asthma prevalence was observed in areas with a higher proportion of Indigenous individuals (PR = 1.13, 95% CrI 1.10-1.17). CONCLUSIONS: We identified significant geographic variation in asthma prevalence and sociodemographic predictors associated with the variation, which may help in designing targeted asthma management strategies and considerations for service enhancement for children in socially deprived areas.

Diabetes-related amputations in Germany: analysis of time trend from 2015 to 2022 and differences by area-level socioeconomic deprivation.

Background: Diabetes-related amputations reduce health-related quality of life and are an indicator of the quality of care of diabetes. Methods: Population-based age-standardized rates for diabetes-related cases of major and minor amputation were calculated and reported for the years 2015 - 2022 using the Diagnosis-related groups statistics. For 2022 these rates were also reported according to area-level socioeconomic deprivation. Results: Diabetes-related major amputations decreased from 6.8 to 5.2 per 100,000 residents in women and from 18.6 to 17.5 per 100,000 residents in men between 2015 and 2022. In 2021 and 2022, there was no further decrease in men compared to the previous year. Diabetes-related minor amputations decreased in women between 2015 and 2022, but increased in men. Amputation rates were higher in regions with high deprivation than in regions with low deprivation. Conclusions: Diabetes care should consider socioeconomic differences into account. The monitoring of the trends in amputations needs to be continued.

Prevalence of gestational diabetes mellitus in Germany: Temporal trend and differences by regional socioeconomic deprivation.

Background: Gestational diabetes mellitus (GDM) increases the risk for adverse pregnancy outcomes. In 2012, a general screening for GDM was introduced in Germany. Methods: The analysis is based on data from the external inpatient quality assurance for obstetrics from the years 2013 to 2021. Women with pregestational diabetes were excluded. GDM was defined either by documentation in the maternity record or by ICD diagnosis O24.4 during hospitalisation. We reported the prevalence stratified by year, maternal age and regional socioeconomic deprivation. Results: The age-standardized prevalence of GDM continuously rose from 4.7 % in 2013 to 8.5 % in 2021. The increase was observed in all age groups. In 2021, this corresponded to 63,563 women with GDM. The prevalence was higher in highly deprived regions than in low deprived regions. Conclusion: A steady increase in GDM prevalence and evidence of health inequalities emphasise the need for primary prevention strategies for GDM.

Vascular service provision during the COVID-19 pandemic worsened major amputation rates in socially deprived diabetic populations.

Introduction: The Coronavirus Disease - 2019 (COVID-19) pandemic significantly impacted healthcare service provision and put diabetic patients at increased risk of adverse health outcomes. We aimed to assess the impact of the COVID-19 pandemic on the incidence and demographic shift of major lower-limb amputation in diabetic patients. Methods: We performed a retrospective analysis of diabetic patient records undergoing major lower-limb amputation between 01/03/2019 and 01/03/2021 at the Royal Sussex County Hospital, the regional arterial hub for Sussex. Primary outcomes were amputation incidence rates and patient demographics compared between the prepandemic and pandemic cohorts. Results: The incidence rate ratio of major lower-limb amputations shows a drop in amputations during the pandemic compared to pre-pandemic (IRR 0.82; 95% CI 0.57-1.18). Data suggests a shift in the social deprivation background of patients receiving amputations to disproportionately affect those in the more deprived 50% of the population (p=0.038). Younger patients received more amputations during the pandemic compared to prepandemic levels (p=0.001). Conclusion: Results suggest that during the COVID-19 pandemic there was a paradoxical reduction in amputations compared to prepandemic levels. However, changes to the demographic makeup of patient's receiving amputations are alarming as younger, and more deprived patients have been disproportionately affected by the pandemic.

Differential effects of obesity on perioperative outcomes in renal cell carcinoma patients based on race and ethnicity and neighborhood-level socioeconomic status.

Background: Obesity is a well-established risk factor of renal cell carcinoma (RCC), however the impact of obesity on surgical outcomes for racial and ethnic minority patients with RCC is unclear. This study investigated whether a higher body mass index (BMI) or obesity (BMI ≥30 kg/m2) was associated with worse perioperative outcomes and if there were heterogeneous effects based on race, ethnicity, and neighborhood-level socioeconomic factor. Methods: In this single-center cross-sectional study, medical records of patients who underwent partial or radical nephrectomy between 2010 and 2022 were retrospectively reviewed. Logistic regression analysis was performed to assess associations of BMI and perioperative outcomes [ischemia time, estimated blood loss (EBL), and length of hospital stay]. Results: A total of 432 patients, including 49.8% non-Hispanic White (NHW), 35.0% Hispanic, and 6.9% American Indian (AI) patients, were included. Median [interquartile range (IQR)] BMI was 30.2 (26.3-35.2) kg/m2, and Hispanic (31.5) and AI (32.5) patients had higher median BMI than NHW (29.1) patients (P=0.006). Median ischemia time, EBL, and length of hospital stay were 18.5 (IQR, 15.0-22.4) minutes, 150 (IQR, 75.0-300.0) mL, and 3 (IQR, 2-5) days. BMI ≥35 kg/m2 was associated with a longer ischemia time [>18.5 minutes; odds ratio (OR), 5.17; 95% confidence interval (CI): 1.81-14.76; P=0.002], and the association was stronger in NHW than Hispanic patients (BMI continuous OR, 1.13; 95% CI: 1.04-1.22; P=0.004 in NHW and OR, 1.07; 95% CI: 0.98-1.17; P=0.12 in Hispanics). Class I and II/III obese patients had over two-fold increased odds of a larger EBL (>150 mL) than patients with normal weight (OR, 2.17; 95% CI: 1.03-4.59; P=0.04 for class I and OR, 2.24; 95% CI: 1.04-4.84; P=0.04 for class II/III obese patients). This association was stronger in patients from neighborhoods with high social deprivation index (SDI) and in NHW patients (BMI ≥30 vs. <30 kg/m2, OR, 3.53; 95% CI: 1.57-7.97; P=0.002 in high SDI neighborhoods and OR, 2.38; 95% CI: 1.10-5.14; P=0.03 in NHW). BMI was not associated with a longer hospital stay. Conclusions: In this study, obesity increased likelihood of worse perioperative outcomes, and the associations varied based on race and ethnicity and neighborhood-level socioeconomic factors.
