Process and Outcome Measures for Infants Born Moderate and Late Preterm in Tertiary Canadian Neonatal Intensive Care Units.

OBJECTIVE: To describe the prevalence of and between-center variations in care practices and clinical outcomes of moderate and late preterm infants (MLPIs) admitted to tertiary Canadian neonatal intensive care units (NICUs). STUDY DESIGN: This was a retrospective cohort study including infants born at 320/7 through 366/7 weeks of gestation and admitted to 25 NICUs participating in the Canadian Neonatal Network between 2015 and 2020. Patient characteristics, process measures represented by care practices, and outcome measures represented by clinical in-hospital and discharge outcomes were reported by gestational age weeks. NICUs were compared using indirect standardization after adjustment for patient characteristics. RESULTS: Among 25 669 infants (17% of MLPIs born in Canada during the study period) included, 45% received deferred cord clamping, 7% had admission hypothermia, 47% received noninvasive respiratory support, 11% received mechanical ventilation, 8% received surfactant, 40% received antibiotics in the first 3 days, 4% did not receive feeding in the first 2 days, and 77% had vascular access. Mortality, early-onset sepsis, late-onset sepsis, or necrotizing enterocolitis occurred in <1% of the study cohort. Median (IQR) length of stay was 14 (9-21) days among infants discharged home from the admission hospital and 5 (3-9) days among infants transferred to community hospitals. Among infants discharged home, 33% were discharged on exclusive breastmilk and 75% on any breastmilk. There were significant variations between NICUs in all process and outcome measures. CONCLUSIONS: Care practices and outcomes of MLPIs varied significantly between Canadian NICUs. Standardization of process and outcome quality measures for this population will enable benchmarking and research, facilitating systemwide improvements.

Association Between the Use of an Adaptive Cardiac Resynchronization Therapy Algorithm and Health Care Use and Cost.

OBJECTIVES: To assess the association between the use of adaptive pacing on clinical and economic outcomes of cardiac resynchronization therapy (CRT) recipients in a real-world analysis. BACKGROUND: The adaptivCRT (aCRT) algorithm was shown in prior subgroup analyses of prospective trials to achieve clinical benefits, but a large prospective trial showed nonsignificant changes in the endpoint of mortality or hospitalizations due to heart failure. METHODS: CRT-implanted patients from the Optum Clinformatics database with ≥ 90 days of follow-up were included. Remote monitoring data were used to classify patients based on CRT setting-adaptive biventricular and left ventricular pacing (aCRT) vs standard biventricular pacing (Standard CRT). Inverse probability of treatment weighting was used to adjust for baseline differences between groups. Mortality, 30-day readmissions, health care use, and payer and patients' costs were evaluated post-implantation. RESULTS: This study included 2412 aCRT and 1638 Standard CRT patients (mean follow-up: 2.4 ± 1.4 years), with balanced baseline characteristics after adjustment. The aCRT group was associated with lower all-cause mortality rates (adjusted hazard ratio = 0.88 [95% confidence interval (CI):0.80, 0.96]), fewer all-cause 30-day readmissions (adjusted incidence rate ratio = 0.87 [CI:0.81, 0.94]), and fewer all-cause and HF-related inpatient, outpatient and emergency department visits. The aCRT cohort was also associated with lower all-cause outpatient payer-paid amounts and lower all-cause and HF-related inpatient and emergency department patient-paid amounts. CONCLUSIONS: In this retrospective analysis of a large real-world cohort, the use of an adaptive CRT algorithm was associated with lower mortality rates, reduced health care resource use and lower payer and patient costs.

Vrba was right: Historical climate fragmentation, and not current climate, explains mammal biogeography.

Climate plays a crucial role in shaping species distribution and evolution over time. Dr Vrba's Resource-Use hypothesis posited that zones at the extremes of temperature and precipitation conditions should host a greater number of climate specialist species than other zones because of higher historical fragmentation. Here, we tested this hypothesis by examining climate-induced fragmentation over the past 5 million years. Our findings revealed that, as stated by Vrba, the number of climate specialist species increases with historical regional climate fragmentation, whereas climate generalist species richness decreases. This relationship is approximately 40% stronger than the correlation between current climate and species richness for climate specialist species and 77% stronger for generalist species. These evidences suggest that the effect of climate historical fragmentation is more significant than that of current climate conditions in explaining mammal biogeography. These results provide empirical support for the role of historical climate fragmentation and physiography in shaping the distribution and evolution of life on Earth.

High disease burden and healthcare resource usage in patients with acute porphyria-A population-based analysis.

BACKGROUND AND AIMS: Acute porphyria is a chronic recurrent disease with late diagnosis, heterogeneous clinical presentations and potentially devastating complications. The study aimed at providing real-world evidence on the natural course of acute porphyria, patient characteristics, disease burden, and healthcare utilization before diagnosis. METHODS: This observational study used anonymized claims data covering 8 365 867 persons from German statutory health insurance, spanning 6 years (2015-2020). Patients with at least one diagnosis of acute porphyria during the index period (2019-2020) were classified into three groups by attack frequency. These findings were compared with two age- and sex-adjusted reference groups: the general population and fibromyalgia patients. Prevalence over the index period was calculated for all porphyria patients and those with active acute porphyria. RESULTS: We revealed a prevalence of 79.8 per 1 000 000 for acute porphyria, with 12.9 per 1 000 000 being active cases. Acute porphyria patients, particularly with frequent attacks, demonstrated a higher comorbidity burden compared to the general population. Within the year before the recorded diagnosis, patients with acute porphyria required a median of 23.0 physician visits, significantly higher than the general population's 16.0. Additionally, 33.8% were hospitalized at least once during this period, a notably higher proportion than the general population (19.3%). CONCLUSIONS: This study's findings, collected before the introduction of givosiran, as the first approved preventive therapy for acute porphyria in Europe, highlight the need for healthcare strategies and policies tailored to the complex needs of acute porphyria patients. The significant healthcare demands, heightened comorbidity burden, and increased healthcare system utilization emphasize the urgency of developing a comprehensive support infrastructure for these patients. Also, these acute porphyria real-world findings provide additional insights on disease characteristics in Germany.

Healthcare resource use and costs associated with the misdiagnosis of migraine.

OBJECTIVE: To compare healthcare resource utilization and healthcare costs in patients with migraine with or without a history of misdiagnosis. BACKGROUND: Despite the high prevalence of migraine, migraine is commonly misdiagnosed. The healthcare resource use and cost burden of a misdiagnosis is unknown. METHODS: This retrospective cohort study identified adults with an incident migraine diagnosis from the Merative™ Marketscan® Commercial and Medicare Supplemental Databases between June 2018 and 2019. Patients with a diagnosis of commonly considered misdiagnoses (headache, sinusitis, or cervical pain) before their migraine diagnosis were classified as the "misdiagnosed cohort." Patients in the misdiagnosed cohort were potentially misdiagnosed, then eventually received a correct diagnosis. Patients without a history of commonly considered misdiagnoses prior to their migraine diagnosis were classified as the "correctly diagnosed cohort." Healthcare resource utilization and healthcare costs were assessed in the period before migraine diagnosis and compared between the cohorts. Outcomes were reported as per patient per month and compared with incidence rate ratios. RESULTS: A total of 29,147 patients comprised the correctly diagnosed cohort and 3841 patients comprised the misdiagnosed cohort and met the inclusion criteria. Patients in the misdiagnosed cohort had statistically significantly higher rates of inpatient admissions (0.02 vs. 0.01, incidence rate ratio [IRR] 1.61, 95% confidence interval [CI] 1.47-1.74), emergency department visits (0.10 vs. 0.05; IRR 1.89, 95% CI 1.79-1.99), neurologist visits (0.12 vs. 0.02; IRR 5.95, 95% CI 5.40-6.57), non-neurologist outpatient visits (2.64 vs. 1.58; IRR 1.67, 95% CI 1.62-1.72) and prescription fills (2.82 vs. 1.84; IRR 1.53, 95% CI 1.48-1.58) compared to correctly diagnosed patients. Misdiagnosed patients had statistically significantly higher rates of healthcare cost accrual for inpatient admissions ($1362 vs. $518; IRR 2.62, 95% CI 2.50-2.75), emergency department visits ($222 vs. $98; IRR 2.27, 95% CI 2.18-2.36), neurologist visits ($42 vs. $9; IRR 4.39, 95% CI 4.00-4.79), non-neurologist outpatient visits ($1327 vs. $641; IRR 2.07, 95% CI 1.91-2.24), and prescription fills ($305 vs. $215; IRR 1.41, 95% CI 1.18-1.70) compared to correctly diagnosed patients. CONCLUSION: Patients with migraine who have a history of misdiagnoses have higher rates of healthcare resource utilization and cost accrual versus those without such history.

Impact of headache frequency and preventive treatment failure on quality of life, disability, and direct and indirect costs among individuals with episodic migraine in the United States.

OBJECTIVE: To evaluate unmet needs among individuals with episodic migraine (EM) in the United States (US). BACKGROUND: Data are limited on the impact of headache frequency (HF) and preventive treatment failure (TF) on the burden of migraine in the US. METHODS: A retrospective, cross-sectional analysis of 2019 National Health and Wellness Survey (NHWS) data was conducted from an opt-in online survey that identified respondents (aged ≥18 years) in the US with self-reported physician-diagnosed migraine. Participants were stratified by HF (low: 0-3 days/month; moderate-to-high: 4-14 days/month) and prior preventive TF (preventive naive; 0-1 TF; ≥2 TFs). Comparisons were conducted between preventive TF groups using multivariable regression models controlling for patient demographic and health characteristics. RESULTS: Among individuals with moderate-to-high frequency EM, the NHWS identified 397 with ≥2 TFs, 334 with 0-1 TF, and 356 as preventive naive. The 36-item Short-Form Health Survey (version 2) Physical Component Summary scores were significantly lower among those with ≥2 TFs, at a mean (standard error [SE]) of 41.4 [0.8] versus the preventive-naive 46.8 [0.9] and 0-1 TF 44.5 [0.9] groups; p < 0.001 for both). Migraine Disability Assessment Scale scores were significantly higher in the ≥2 TFs, at a mean (SE) of 37.7 (3.9) versus preventive-naive 26.8 (2.9) (p < 0.001) and 0-1 TF 30.1 (3.3) (p = 0.011) groups. The percentages of time that respondents experienced absenteeism (mean [SE] 21.6% [5.5%] vs. 13.4% [3.6%]; p = 0.022), presenteeism (mean [SE] 55.0% [8.3%] vs. 40.8% [6.5%]; p = 0.015), overall work impairment (mean [SE] 59.4% [5.6%] vs. 45.0% [4.4%]; p < 0.001), and activity impairment (mean [SE] 56.8% [1.0%] vs. 44.4% [0.9%]; p < 0.001) were significantly higher in the ≥2 TFs versus preventive-naive group. Emergency department visits (preventive-naive, p = 0.006; 0-1 TF, p = 0.008) and hospitalizations (p < 0.001 both) in the past 6 months were significantly higher in the ≥2 TFs group. Direct and indirect costs were significantly higher in the ≥2 TFs (mean [SE] $24,026 [3460]; $22,074 [20]) versus 0-1 TF ($10,897 [1636]; $17,965 [17]) and preventive-naive ($11,497 [1715]; $17,167 [17]) groups (p < 0.001 for all). Results were similar in the low-frequency EM group. CONCLUSIONS: In this NHWS analysis, individuals with more prior preventive TFs experienced significantly higher humanistic and economic burden regardless of HF.

A Comprehensive Accounting of Construction Materials in Belt and Road Initiative Projects.

The Belt and Road Initiative (BRI) stands as the most ambitious infrastructure project in history, marked by its scale of investment, extensive geographical reach across continents and countries, and a diverse array of projects from roads to digital networks. While the BRI's environmental sustainability has raised concerns, the impacts of construction materials used in these projects have been overlooked, especially in developing countries. Here, we map and account for the materials embodied in the BRI by integrating, for the first time, official governmental project reports, geographical information, and material flow analysis. We pinpoint and analyze the BRI material stocks in each individual project by material types, countries, regions, and sectors. Between 2008 and 2023, 328 million tons of construction materials have accumulated in 540 BRI projects around the world, mostly in Asia and Africa. Aggregates (sand and gravel) constitute the largest share (82%), followed by cement, steel, and other materials. Most of the materials are used in transportation infrastructure. Our work further highlights some limitations in terms of data quality for such sustainability assessments. By shedding light on the significant impact of BRI projects on raw material usage across the globe, this study sets the stage for further investigations into environmental impacts of BRI and material stock-flow-nexus from perspective of an initiative.

Burden of respiratory syncytial virus (RSV) infection in Germany: a systematic review.

BACKGROUND: Respiratory syncytial virus (RSV) is a major cause of acute lower respiratory infection and hospitalizations among infants, young children, and the elderly. This systematic literature review aimed to summarize the epidemiological and economic burden estimates of RSV infection at any age in Germany. METHODS: We conducted a systematic literature search to identify full-text articles published from 2003 to 2023 and reporting data on the epidemiological or economic burden of RSV in Germany. Based on pre-specified eligibility criteria, data on incidence, rates of hospital and intensive care unit (ICU) admission, clinical manifestation, underlying conditions, seasonality, health care resource use and costs were extracted. RESULTS: After screening 315 full-text articles, we included 42 articles in the review. The characteristics of the included studies were heterogenous regarding study population, setting, age groups and RSV-related outcome measures. The most frequently reported epidemiological outcome measures were RSV detection rate (n = 33), followed by clinical manifestation (n = 19), seasonality (n = 18), and underlying conditions of RSV infection (n = 13). RSV detection rates were reported across heterogenous study populations, ranging from 5.2 to 55.4% in pediatric inpatient cases and from 2.9 to 14% in adult inpatient cases. All articles that reported RSV detection rates across several age groups demonstrated the highest burden in infants and young children. Few articles reported RSV-related outcome measures distinctively for the outpatient setting. Health care resource use, such as hospital length of stay, ICU admission rate and treatment of patients with RSV infection were described in 23 articles, of which only one study quantified associated costs from 1999 to 2003 for children ≤ 3 years. In-hospital ICU admission rates varied between 3.6 and 45%, depending on population characteristics as age and underlying conditions. CONCLUSIONS: This systematic review revealed that RSV imposes substantial disease burden in infants, young children, and the elderly in Germany, whereby infants are particularly affected. To date, there has been limited exploration of the impact of RSV infection on healthy children or the elderly in Germany. Given their notably high reported burden in studies, the medical and economic RSV burden in these groups should move more into focus.

Potential healthcare resource use and associated costs of every 2 month injectable cabotegravir plus rilpivirine long-acting regimen implementation in the Spanish National Healthcare System compared to daily oral HIV treatments.

INTRODUCTION: HIV treatment currently consists of daily oral antiretroviral therapy (ART). Cabotegravir + rilpivirine long-acting (CAB + RPV LA) is the first ART available in Spain administered every 2 months through intramuscular injection by a healthcare professional (HCP). The objective of this analysis was to assess potential healthcare resource use (HRU) and cost impact of implementing CAB + RPV LA vs. daily oral ART at National Health System (NHS) hospitals. METHODS: Online quantitative interviews and cost analysis were performed. Infectious disease specialists (IDS), hospital pharmacists (HP) and nurses were asked about their perception of potential differences in HRU between CAB + RPV LA vs. daily oral ART, among other concepts of interest. Spanish official tariffs were applied as unit costs to the HRU estimates (€2022). RESULTS: 120 responders (n = 40 IDS, n = 40 HP, n = 40 nurses) estimated an average number of annual visits per patient by speciality (IDS, HP, and nurse, respectively) of 3.3 vs. 3.7; 4.4 vs. 6.2; 6.1 vs. 3.9, for CAB + RPV LA vs. daily oral ART, and 3.0 vs. 3.2; 4.8 vs. 5.8; 6.9 vs. 4.9, respectively when adjusting by corresponding specialist responses. Estimation by the total sample led to an annual total cost per patient of €2,076 vs. €2,473, being €2,032 vs. €2,237 after adjusting by corresponding HCP, for CAB + RPV LA vs. daily oral ART. CONCLUSIONS: These results suggest that the implementation of CAB + RPV LA in NHS hospitals would not incur in increased HRU-related costs compared to current daily oral ARTs, being potentially neutral or even cost-saving.

Intraspecific variation in crayfish behavioral traits affects leaf litter breakdown in streams.

Although intraspecific trait variation is increasingly recognized as affecting ecosystem processes, few studies have examined the ecological significance of among-population variation in behavioral traits in natural ecosystems. In freshwater habitats, crayfish are consumers that can influence ecosystem structure (e.g., macroinvertebrate communities) and function (e.g., leaf litter breakdown). To test whether crayfish behavioral traits (activity, boldness, and foraging voracity) are major contributors of leaf litter breakdown rates in the field, we collected rusty crayfish (Faxonius rusticus) from eight streams across the midwestern USA and measured behaviors using laboratory assays. At the same streams, we measured breakdown rates of leaf packs that were accessible or inaccessible to crayfish. Our results provide evidence that among-population variation in crayfish boldness and foraging voracity was a strong predictor of leaf litter breakdown rates, even after accounting for commonly appreciated environmental drivers (water temperature and human land use). Our results suggest that less bold rusty populations (i.e., emerged from shelter more slowly) had greater direct impacts on leaf litter breakdown than bold populations (P = 0.001, r2 = 0.85), potentially because leaf packs can be both a shelter and food resource to crayfish. Additionally, we found that foraging voracity was negatively related to breakdown rates in leaf packs that were inaccessible to crayfish (P = 0.025, r2 = 0.60), potentially due to a trophic cascade from crayfish preying on other invertebrates that consume leaf litter. Overall, our results add to the growing evidence that trait variation in animals may be important for understanding freshwater ecosystem functioning.

Impact of moderate-to-high-suicide-intent in major depressive disorder: a retrospective cohort study on patient characteristics and healthcare resource utilisation in England.

BACKGROUND: Major depressive disorder (MDD) is a disabling mental illness that can affect all aspects of daily life and is a leading cause of healthcare resource utilisation (HCRU). AIMS: We aimed to characterise patients with MDD with moderate-to-high-suicide-intent, compare their HCRU to patients with MDD without moderate-to-high-suicide-intent, and better understand their patient pathways. METHODS: This retrospective cohort study used data collected from primary care electronic health records from Clinical Practice Research Datalink (CPRD), linked to Hospital Episode Statistics, Mental Health Services Data Set, and Office for National Statistics in England. Adults diagnosed with ≥ 1 MDD diagnosis between 04/2007 and 11/2015 were categorised by suicide intent. RESULTS: 307,476 patients with MDD were included (294,259 patients without moderate-to-high-suicide-intent and 13,217 with moderate-to-high-suicide-intent). Patients with MDD with moderate-to-high-suicide-intent were younger on average (39.0 vs. 44.8 years) and included a lower percentage of females (58% vs. 65%) compared to patients without moderate-to-high-suicide-intent. HCRU was greater among patients with moderate-to-high-suicide-intent than patients without moderate-to-high-suicide-intent during the first follow-up year for general practitioner consultations (38.5 vs. 29.4), psychiatric outpatient visits (1.5 vs. 0.1), psychiatrist visits (3.6 vs. 0.3), emergency visits (1.5 vs. 0.3), and hospitalisations (86% vs. 26%). Overall, 56% of patients with moderate-to-high-suicide-intent had an antidepressant prescription within 30 days from the initial moderate-to-high-suicide-intent. CONCLUSIONS: Patients with MDD and moderate-to-high-suicide-intent were younger, included more males and incurred greater HCRU than those without moderate-to-high-suicide-intent. These results suggest a greater need for effective medical care and appropriate treatments for patients with moderate-to-high-suicide-intent, which could help reduce associated symptoms, mortality, and HCRU.

Nationwide epidemiology and health resource use among children with COVID-19 in Japan.

BACKGROUND: The COVID-19 pandemic posed substantial challenges to healthcare systems. Understanding the responses of pediatric health services is crucial for future pandemic planning and preparedness, yet such data remains limited. METHODS: In this retrospective cohort study, we analyzed data from administrative databases developed by Japan Medical Data Center and DeSC Healthcare Inc. The dataset comprised records of 2,612,511 children, totaling 60,224,888 person-months, from January 2020 to May 2022. Multivariate generalized estimation equations were used to examine the incidence rates of COVID-19 and associated health resource use. RESULTS: Our analysis revealed that the incidence rates of COVID-19 gradually increased from Wave I (2.2 cases per 100,000 person-months) to Wave V (177.8cases per 100,000 person-months), with a notable elevation during Wave VI (2367.7 cases per 100,000 person-months). While nucleic acid amplification tests were primarily used during Waves I-V, the use of rapid antigen tests markedly increased in Wave VI. The hospitalization rates increased gradually from 0.2 in Wave I to 10.2 events per 100,000 person-months in Wave VI, and the case-hospitalization risk decreased from 14.9% in Wave II to 0.7% in Wave VI. Additionally, we observed decreasing trends in the use of antibiotics (Wave I, 31.8%; Wave VI, 9.0%), whereas antipyretic use rose from Wave I (56.1%) to Wave VI (86.6%). CONCLUSIONS: Our study highlighted essential changes in the nationwide pediatric healthcare system's response to the COVID-19 pandemic. These findings provide valuable insights into the future pandemic planning and preparedness.

Clinical and economic burden of acute exacerbations of idiopathic pulmonary fibrosis: a prospective observational study in Spain (OASIS study).

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a fatal progressive lung disease entailing significant impairment in health-related quality of life (HRQoL) and high socioeconomic burden. The course of IPF includes episodes of acute exacerbations (AE-IPF) leading to poor outcomes. This study aimed to compare management, costs and HRQoL of patients with AE-IPF to patients without AE-IPF during one year in Spain. MATERIALS AND METHODS: In a 12-month, prospective, observational, multicenter study of IPF patients, healthcare resource use was recorded and costs related to AE-IPF were estimated and compared between patients with and without AE-IPF. HRQoL was measured with the St. George's Respiratory Questionnaire (SGRQ), EuroQoL 5 dimensions 5 levels questionnaire (EQ-5D-5L), EQ-5D visual analogue scale (EQ-VAS) and the Barthel Index. RESULTS: 204 IPF patients were included: 22 (10.8%) experienced ≥ 1 acute exacerbation, and 182 (89.2%) did not. Patients with exacerbations required more primary care visits, nursing home visits, emergency visits, hospital admissions, pharmacological treatments and transport use (p < 0.05 for all comparisons). Likewise, patients with exacerbations showed higher annual direct health AE-IPF-related costs. In particular, specialized visits, emergency visits, days of hospitalization, tests, palliative care, transport in ambulance and economic aid (p < 0.05 for all comparisons). Exploratory results showed that patients with AE-IPF reported a non-significant but substantial decline of HRQoL compared with patients without AE-IPF, although causality can be inferred. CONCLUSION: We observed significantly higher resource use and cost consumption and lower HRQoL among patients suffering exacerbations during the study. Thus, preventing or avoiding AE-IPF is key in IPF management.

An analysis of the diagnoses and costs of pediatric emergency care visits: a single center study.

BACKGROUND: Children's emergency care visits are common, although the costs and reasons for visits vary. This register-based study examines the costs of pediatric emergency care and the diagnoses related to visits made to the Pediatric Emergency Unit at Tampere University Hospital (Tays), Tampere, Finland. METHODS: This retrospective study described pediatric emergency care visits made between September 2018 and December 2019 to a single center in Tampere, Finland. The data were gathered from medical files and from cost-per-patient software and analyzed in groups by age, season, level of treatment in the ED (primary or secondary), and hospitalization, as well as by diagnosis groups. RESULTS: During the study period, 11,454 visits were made. The total costs were over €3,380,000 ($2,837,758), with a median cost per visit was €260 ($217.90). Higher costs were associated with hospitalization and treatment in secondary care. The most common diagnoses were respiratory tract infections, counseling, other infections, GI symptoms, and other reasons. CONCLUSION: Seriously ill children incur the highest costs per visit in pediatric emergency care. Respiratory tract infections are common reasons for emergency care visits, and the reasons why children come to emergency care in Finland are similar to those in other countries.

Health inequalities and their relationship with socioeconomic indicators in the Maresme region (Catalonia): A cross-sectional ecological study.

OBJECTIVE: Health inequalities are universal, but their magnitude and determinants vary according to geographic areas, and understanding variations is essential to designing and implementing preventive and corrective policies. Our objective was to evaluate health inequalities in the Maresme region (Catalonia, Spain) and the relationship with socioeconomic indicators. DESIGN: Cross-sectional ecological study (2017). SITE: Maresme region. PARTICIPANTS: Population assigned to any of the Maresme's 21 basic health areas (BHAs). MEASURES: Sociodemographic, socioeconomic, health, and health resource use indicators published by the Catalan Health Service's Information and Knowledge Unit. RESULTS: Differences observed between BHAs were 49% in mortality, 266% in diabetes incidence, 348% in stroke incidence, and 89% in hospitalizations. In the most compared to the least disadvantaged BHAs, socioeconomic deprivation, as measured by the socioeconomic index (SEI), was 4.6 times greater and the percentage population with low educational attainment (EA) was 3.7 times higher. Greater deprivation was associated with greater prevalence of diabetes, chronic obstructive pulmonary disease, and high blood pressure, and greater incidence of diabetes, ischemic heart disease, and cancer. Likewise, a greater percentage population with low EA was associated with higher premature mortality and avoidable hospitalizations. CONCLUSION: Great variation exists in socioeconomic, health, and health resource use between the different Maresme BHAs. Socioeconomic deprivation is strongly correlated with the prevalence and incidence of certain chronic diseases, and low EA is correlated with premature mortality and avoidable hospitalizations. Our findings point to the urgency of taking health inequalities into account in designing and implementing healthcare strategies, programs, and policies.

Relationship between Diagnostic Method and Pathogen Detection, Healthcare Resource Use, and Cost in U.S. Adult Outpatients Treated for Acute Infectious Gastroenteritis.

A retrospective observational study was performed to assess the relationship between diagnostic method (traditional work-up [TW], multiplex PCR panel with < 12 target pathogens [PCR < 12], or multiplex PCR panel with ≥ 12 target pathogens [PCR12]), and diagnostic yield, health care resource use (HRU), and cost in adult outpatients visiting U.S. hospitals for acute infectious gastroenteritis (AGE). Using data from PINC AI Healthcare Database during January 1, 2016-June 30, 2021, we analyzed adult patients with an AGE diagnosis and stool testing performed during an outpatient visit. Detection rates for different pathogens were analyzed for those with microbiology data available. Among 36,787 patients, TW was most often performed (57.0%). PCR12 testing was more frequent in patients from large, urban, and teaching hospitals, compared to TW (all P < 0.01). PCR12 was associated with a higher mean index visit cost (by $97) but lower mean 30-day AGE-related follow-up cost (by $117) than TW. Patients with PCR12 had a lower 30-day AGE-related hospitalization risk than TW (1.7% versus 2.7% P < 0.01). Among the 8,451 patients with microbiology data, PCR12 was associated with fewer stool tests per patient (mean 1.61 versus 1.26), faster turnaround time (mean 6.3 versus 25.7 h) and lower likelihood of receiving in-hospital antibiotics (39.4% versus 47.1%, all P < 0.01) than TW. A higher percentage of patients with PCR12 had a target pathogen detected (73.1%) compared to PCR < 12 (63.6%) or TW (45.4%, P < 0.01). Thus, we found that large multiplex PCR panels were associated with lower 30-day AGE-related follow-up cost and risk of AGE-related hospitalization, and increased diagnostic yield compared to TW.

Estimating the hospital costs of care for people living with HIV in England using routinely collected data.

BACKGROUND: Understanding the health care activity and associated hospital costs of caring for people living with HIV is an important component of assessing the cost effectiveness of new technologies and for budget planning. METHODS: Data collected between 2010 and 2017 from an English HIV treatment centre were combined with national reference costs to estimate the rate of hospital attendances and costs per quarter year, according to demographic and clinical factors. The final dataset included records for 1763 people living with HIV, which was analysed using negative binomial regression models and general estimating equations. RESULTS: People living with HIV experienced an unadjusted average of 0.028 (standard deviation [SD] 0.20) inpatient episodes per quarter, equivalent to one every 9 years, and 1.85 (SD 2.30) outpatient visits per quarter. The unadjusted mean quarterly cost per person with HIV (excluding antiretroviral drug costs) was £439 (SD 604). Outpatient appointments and inpatient episodes accounted for 88% and 6% of total costs, respectively. In adjusted models, low CD4 count was the strongest predictor of inpatient stays and outpatient visits. Low CD4 count and new patient status (having a first visit at the Trust in the last 6 months) were the factors that most increased estimated costs. Associations were weaker or less consistent for demographic factors (age, sex/sexual orientation/ethnicity). Sensitivity analyses suggest that the findings were generally robust to alternative parameter and modelling assumptions. CONCLUSION: A number of factors predicted hospital activity and costs, but CD4 cell count and new patient status were the strongest. The study results can be incorporated into future economic evaluations and budget impact assessments of HIV-related technologies.

Urbanization shifts long-term phenology and severity of phytoplankton blooms in an urban lake through different pathways.

Climate change can induce phytoplankton blooms (PBs) in eutrophic lakes worldwide, and these blooms severely threaten lake ecosystems and human health. However, it is unclear how urbanization and its interaction with climate impact PBs, which has implications for the management of lakes. Here, we used multi-source remote sensing data and integrated the Virtual-Baseline Floating macroAlgae Height (VB-FAH) index and OTSU threshold automatic segmentation algorithm to extract the area of PBs in Lake Dianchi, China, which has been subjected to frequent PBs and rapid urbanization in its vicinity. We further explored long-term (2000-2021) trends in the phenological and severity metrics of PBs and quantified the contributions from urbanization, climate change, and also nutrient levels to these trends. When comparing data from 2011-2021 to 2000-2010, we found significantly advanced initiation of PBs (28.6 days) and noticeably longer duration (51.9 days) but an insignificant trend in time of disappearance. The enhancement of algal nutrient use efficiency, likely induced by increased water temperature and reduced nutrient concentrations, presumably contributed to an earlier initiation and longer duration of PBs, while there was a negative correlation between spring wind speed and the initiation of PBs. Fortunately, we found that both the area of the PBs and the frequency of severe blooms (covering more than 19.8 km2 ) demonstrated downward trends, which could be attributed to increased wind speed and/or reduced nutrient levels. Moreover, the enhanced land surface temperature caused by urbanization altered the thermodynamic characteristics between the land and the lake, which, in turn, possibly caused an increase in local wind speed and water temperature, suggesting that urbanization can differently regulate the phenology and severity of PBs. Our findings have significant implications for the understanding of the impacts of urbanization on PB dynamics and for improving lake management practices to promote sustainable urban development under global change.

The essential role of biodiversity in the key axes of ecosystem function.

Biodiversity is essential for maintaining the terrestrial ecosystem multifunctionality (EMF). Recent studies have revealed that the variations in terrestrial ecosystem functions are captured by three key axes: the maximum productivity, water use efficiency, and carbon use efficiency of the ecosystem. However, the role of biodiversity in supporting these three key axes has not yet been explored. In this study, we combined the (i) data collected from more than 840 vegetation plots across a large climatic gradient in China using standard protocols, (ii) data on plant traits and phylogenetic information for more than 2,500 plant species, and (iii) soil nutrient data measured in each plot. These data were used to systematically assess the contribution of environmental factors, species richness, functional and phylogenetic diversity, and community-weighted mean (CWM) and ecosystem traits (i.e., traits intensity normalized per unit land area) to EMF via hierarchical partitioning and Bayesian structural equation modeling. Multiple biodiversity attributes accounted for 70% of the influence of all the variables on EMF, and ecosystems with high functional diversity had high resource use efficiency. Our study is the first to systematically explore the role of different biodiversity attributes, including species richness, phylogenetic and functional diversity, and CWM and ecosystem traits, in the key axes of ecosystem functions. Our findings underscore that biodiversity conservation is critical for sustaining EMF and ultimately ensuring human well-being.

Limited access to liver transplantation and TIPS despite high mortality, healthcare resource use and costs of cirrhosis in Germany.

BACKGROUND AND AIMS: Data on number of patients with cirrhosis in Germany are limited. We therefore aimed to estimate prevalence, comorbidities, mortality, utilization of healthcare resources and costs of patients with cirrhosis and incidence of decompensation of cirrhosis in Germany. METHODS: This longitudinal observational study was based on an anonymized representative claims database including 4.9 million persons insured by a statutory health insurance (SHI) between 2015-2020. Patients with decompensated and compensated cirrhosis were selected via diagnostic ICD codes and followed for 2 years. RESULTS: Prevalence of cirrhosis in 2015 was 250/100 000, resulting in 201 747 (95% CI: 197 540-206 040) patients extrapolated to the German population. Out of all patients with compensated cirrhosis in 2015 who did not deceased, 16.0% developed a decompensation within 3 years. Overall, 978 patients (Ø-age: 68 years; 60% male) were included in the decompensated, and 5135 patients (Ø-age: 66 years; 59% male) in the compensated cirrhosis cohort. Patients with decompensated cirrhosis had a higher burden of comorbidities (Charlson Comorbidity Index 7.3 vs. 4.4) and 3 times higher costs per quarter (7172 € vs. 2213 €) than patients with compensated cirrhosis. 1-year mortality after decompensation was 51% compared to 8% in compensated cirrhosis. Of note, only few patients with decompensated cirrhosis received a liver transplantation or transjugular intrahepatic portosystemic shunts (TIPS) (1% and 5%). CONCLUSION: Patients with cirrhosis have a high healthcare burden in especially decompensated stage. Accordingly, 1-year mortality of decompensated cirrhosis in Germany is high. Despite high health resource utilization, only few patients have access to liver transplantation or TIPS.
