Robustness assessment of regressions using cluster analysis typologies: a bootstrap procedure with application in state sequence analysis

BackgroundIn standard Sequence Analysis, similar trajectories are clustered together to create a typology of trajectories, which is then often used to evaluate the association between sequence patterns and covariates inside regression models. The sampling uncertainty, which affects both the derivation of the typology and the associated regressions, is typically ignored in this analysis, an oversight that may lead to wrong statistical conclusions. We propose utilising sampling variation to derive new estimates that further inform on the association of interest.MethodsWe introduce a novel procedure to assess the robustness of regression results obtained from the standard analysis. Bootstrap samples are drawn from the data, and for each bootstrap, a new typology replicating the original one is constructed, followed by the estimation of the corresponding regression models. The bootstrap estimates are then combined using a multilevel modelling framework that mimics a meta-analysis. The fitted values from this multilevel model allow to account for the sampling uncertainty in the inferential analysis. We illustrate the methodology by applying it to the study of healthcare utilisation trajectories in a Swiss cohort of diabetic patients.ResultsThe procedure provides robust estimates for an association of interest, along with 95% prediction intervals, representing the range of expected values if the clustering and associated regressions were performed on a new sample from the same underlying distribution. It also identifies central and borderline trajectories within each cluster. Regarding the illustrative application, while there was evidence of an association between regular lipid testing and subsequent healthcare utilisation patterns in the original analysis, this is not supported in the robustness assessment.ConclusionsInvestigating the relationship between trajectory patterns and covariates is of interest in many situations. However, it is a challenging task with potential pitfalls. Our Robustness Assessment of Regression using Cluster Analysis Typologies (RARCAT) may assist in ensuring the robustness of such association studies. The method is applicable wherever clustering is combined with regression analysis, so its relevance goes beyond State Sequence Analysis.

Water utilization practices and wastage at household level: A case study of Lahore City

AbstractThe current research places its emphasis on addressing the issue of water shortage, which, if left unaddressed, could hinder sustainable development in the broader Punjab region, with a particular focus on the city of Lahore. In pursuit of our research objectives, we conducted a comprehensive survey that involved 600 households within Lahore. Our research methodology included the usage of both quantitative and qualitative analysis which included interviews and snowball sampling. Our findings indicate a clear and direct correlation between water shortage and patterns of water utilization and wastage. The absence of sustainable strategies to ensure adequate water supply, efficient resource management, and universal sanitation poses a substantial threat to our future. To address water shortages, it is crucial to encourage the use of water‐saving appliances and fixtures like toilets, low‐flow faucets, and showerheads. The purpose of these measures is to conserve water and align it with sustainable development goals by encouraging resource utilization that is efficient, minimizing environmental impact. By implementing these solutions, both households and border areas can benefit from significant water‐saving practices. Consequently, we recommend that the government implement targeted programs aimed at raising awareness among individuals about responsible water usage and reducing wasteful practices within households.

Are Healthcare Resource Utilization Patterns for Pain Management Specific to Post-Acute COVID-19 Syndrome? A Study of Survivors from the First French Pandemic Wave

Objectives: Chronic pain is a common symptom in Post-Acute COVID-19 Syndrome (PACS), affecting 11–60% of patients, but the link between COVID-19 and chronic pain remains unclear. This study assesses healthcare resource utilization (HRU) for pain management among French COVID-19 survivors, using the National French Claims Database (SNDS). We analyzed medical consultations, rehabilitation services, diagnostic procedures, and medication dispensing to identify PACS-related pain patterns and their impact on the healthcare system. Methods: The cohort included 68,822 patients hospitalized during the first COVID-19 wave (March–June 2020), with 13,939 ICU survivors. HRU was assessed for six months pre- and post-hospitalization in four areas: (1) medical consultations and rehabilitation; (2) pain-related medication dispensing; (3) neuropathic diagnostic procedures; (4) hospital admissions for chronic pain. A post–pre ratio (PP-Ratio) compared post-COVID to pre-COVID HRU. Results: Significant changes in HRU were observed, particularly for ICU survivors. Neurology consultations (PP-Ratio 1.41) and outpatient physical therapy (PP-Ratio 1.69) increased. Dispensing of strong opioids, antiepileptics, anxiolytics, and hypnotics rose, while NSAID use decreased. Hospitalizations for chronic pain also increased (PP-Ratio 1.52). Similar trends were seen among ICU survivors, with notable increases in opioid and antiepileptic use. No distinct PACS-related pain patterns emerged. Conclusions: Non-specific increases in HRU for pain management were found following COVID-19 hospitalization, likely due to disease severity and ICU care rather than PACS-related chronic pain. Further research is needed to explore long-term pain outcomes in this population.

Epidemiology and Management of Moderate to Severe Thyroid Eye Disease in the United States: Analysis of a Healthcare Claims Database.

To estimate the incidence, prevalence, patient characteristics and healthcare utilization patterns of moderate to severe thyroid eye disease (TED) in the United States. Retrospective review of medical and prescription claims data from the Inovalon deidentified claims database. Patients with moderate to severe TED were identified based on specific and sensitive definitions using International Classification of Diseases (ICD) codes selected by a group of TED specialists. The incident moderate to severe TED population included 3364 and 1730 patients using the sensitive and specific definitions, respectively. After adjusting for age and gender, corresponding incidence rates in the sensitive and specific populations were 8.97 (13.49 in women and 4.27 in men) and 4.37 (6.59 in women and 2.05 in men) per 100,000 person-years, respectively. The prevalent population included 16,310 and 8018 patients using the sensitive and specific definitions, respectively, corresponding to adjusted prevalence rates of 44.13 (66.00 in women and 21.39 in men) and 20.55 (31.18 in women and 9.50 in men) per 100,000 persons. A preponderance of women was observed, and comorbidity rates were high, with > 40% of prevalent patients experiencing hypertension. Steroids were the most frequently prescribed medication. The impact of teprotumumab was not captured, since this study only included claims data through 2019. The estimated incidence and prevalence rates of TED demonstrate the considerable impact of this disease in the United States, making the creation of a specific ICD code imperative for effective healthcare planning and management.

Trends and associated factors of mental health diagnoses in Catalan Primary Care (2010-2019).

The prevalence of mental health disorders has significantly increased in recent years, posing substantial challenges to healthcare systems worldwide, particularly primary care (PC) settings. This study examines trends in mental health diagnoses in PC settings in Catalonia from 2010 to 2019 and identifies associated sociodemographic, clinical characteristics, psychopharmacological treatments, and resource utilization patterns. Data from 947,698 individuals without prior severe mental illness, derived from the Data Analytics Program for Health Research and Innovation (PADRIS), were analyzed for this study. Sociodemographic data, diagnoses, and resource utilization were extracted from electronic health records. Descriptive statistics, chi-square tests, Mann-Whitney tests, and a multivariate binary logistic regression were employed to analyze the data. Over the study period, 172,112 individuals (18.2%) received at least one mental health diagnosis in PC, with unspecified anxiety disorder (40.5%), insomnia (15.7%) and unspecified depressive disorder (10.2%) being the most prevalent. The prevalence of these diagnoses increased steadily until 2015 and stabilized thereafter. Significant associations were found between mental health diagnoses, female sex, lower socioeconomic status, higher BMI, and smoking status in a multivariate binary logistic regression. This study highlights a growing burden of stress-related mental health diagnoses in PC in Catalonia, driven by demographic and socioeconomic factors. These findings may be indicative of broader trends across Europe and globally. Addressing this rising prevalence requires innovative approaches and collaborative strategies that extend beyond traditional healthcare resources. Engaging stakeholders is essential for implementing effective, sustainable solutions that promote mental health in Catalonia and potentially inform similar initiatives worldwide.

The health and economic burden of rare endocrine disease: Often ignored, always important.

Rare endocrine diseases (RED) often pose chronic and life-threatening challenges, yet their economic costs and societal impact remains have not been precisely quantified. We obtained patient data from the 2018 Nationwide Inpatient Sample (NIS) and the Nationwide Readmissions Database (NRD), identifying RED patients through International Classification of Diseases, 10th revision codes. The difference of economic burden between RED patients and the control group, including hospital length of stay, hospitalisation costs, and readmission rates, was assessed using chi-square tests. We extracted 638 083 (2.98%) RED-related records from the NIS database. Compared to patients with common conditions, RED patients showed an exceedingly high burden of disease, including significantly extended hospital stays (P < 0.05), elevated total charges (P < 0.05), and heightened mortality rates (P < 0.05). They also had a substantially increased 30-day all-cause readmission rate based on the NRD database (P < 0.05). Although the different subgroups of RED patients had varying patterns of health care utilisation and economic burdens, they all surpassed those of patients with common conditions. There is a need for novel strategies aimed at mitigating the substantial RED-related burdens borne by individuals, families, and society in general, as well as funding for research and clinical trials.

Diverse phenotypes, consistent treatment: a study of 30,997 South Asian and White IBD patients using the UK IBD BioResource.

To evaluate South Asian (SA) and White (WH) inflammatory bowel disease (IBD) phenotypes, and to explore treatment approach variations between these cohorts in the UK using the IBD BioResource database. Differences between WH and SA IBD patients were analysed using demographic, phenotypic and outcome data. Drug utilisation patterns and surgical outcomes were assessed in propensity score-matched (PSM) cohorts with multivariable logistic regression, Cox regression and Kaplan-Meier analysis. 30,997 eligible patients were included. UC was the predominant disease subtype in SA (p<0.001). SA were younger at diagnosis (p<0.001), had a male preponderance (p<0.001), and were less likely to have a smoking history at diagnosis. The SA CD phenotype differed from WH, with less ileal (SA 30.3%, WH 38.4%, p=0.008) and stricturing (SA 16.9%, WH 25.6%, p<0.001) disease, but more perianal disease (SA 38.5%, WH 32.2%, p=0.009). More SA UC patients had extensive disease (SA 41.7%, WH 34.1%, p<0.001). In PSM cohorts, comparing treatments, there were no differences in 5-aminosalicylate, corticosteroid, thiopurine, anti-TNF or vedolizumab use. Survival analysis in matched cohorts showed no difference in time to surgery (CD) or colectomy (UC), and SA ethnicity was not associated with a difference in risk of surgery/colectomy. Demographic and phenotypic differences exist between UK SA and WH IBD patients, highlighting distinct ethnicity-related variance, and the need for a research focus on under-represented populations. In comparing matched SA and WH patients, no disparity in medical and surgical IBD therapy in UK healthcare has been demonstrated: treatment is consistent regardless of ethnicity.

IDENTIFIKASI POLA PEMANFAATAN RUANG UNTUK AKOMODASI PENGINAPAN PADA LAHAN HUNIAN MASYARAKAT DI LINGKUNGAN PERMUKIMAN DESA PELIATAN UBUD

Homestay within residential homes has become increasingly popular among foreign tourists recently. Due to the high demand for this type of accommodation, homestays and guesthouses have begun to emerge within the homes of local residents around Ubud. Houses that were originally intended solely as residences are now undergoing a functional transformation, adding a role as accommodations for tourists. This has created a complexity in spatial needs within one area, ultimately affecting and blending the spatial values traditionally held by the local community. If this trend continues without efforts to harmonize it with local cultural values and architecture, the cultural identity in the spatial patterns and values of traditional residences could fade. The researcher will examine in detail how space utilization patterns for accommodations within Ubud residences are being managed. Further, factors influencing the placement of spaces for lodging buildings will be explored. The results of the study indicate that most space utilization patterns for homestay buildings within residential homes in the village of Peliatan still apply local architectural styles, although there are some adjustments in construction systems and materials used.

Receipt of Medications for Alcohol and Opioid Use Disorders: The Importance of Service Utilization Patterns.

Medications for alcohol use disorder (MAUD) and opioid use disorder (MOUD) are underutilized evidence-based treatments. While patients often receive treatment in multiple medical treatment settings, it is unknown whether certain treatment settings or combinations of settings are associated with increased receipt of MAUD or MOUD. Data from the cross-sectional 2019 National Survey on Drug Use and Health were used to identify treatment settings where adult respondents received any past year alcohol treatment (n = 476, 33% female) or, separately, opioid treatment (n = 337, 38% female). Three-stage latent class analysis assessed the patterns of treatment settings utilization and their associations with receipt of MAUD or MOUD, adjusting for potential confounders. Only 10.9% of those in alcohol treatment received MAUD while 40.9% of those in opioid treatment received MOUD. Analyzing different treatment settings visited by respondents, a four-class model best fit the MAUD sample while a three-class model best fit the MOUD sample. There were significant differences in receipt of MAUD by treatment setting classes in unadjusted models (p < 0.05). There were no significant differences in receipt of MOUD across treatment utilization classes, but MOUD receipt was associated with severity of opioid use in all treatment setting classes. People in treatment for alcohol or opioid use were more likely to receive medication if their use was more severe, and were more likely to receive MAUD if they accessed care in many settings. As MOUD and especially MAUD are underutilized, these findings highlight opportunities to increase access to evidence-based care for alcohol and opioid use disorders.

Patterns of siderophore production and utilization at Station ALOHA from the surface to mesopelagic waters

AbstractThe North Pacific subtropical gyre is a globally important contributor to carbon uptake despite being a persistently oligotrophic ecosystem. Supply of the micronutrient iron to the upper ocean varies seasonally to episodically, and when coupled with rapid biological consumption, results in low iron concentrations. In this study, we examined changes in iron uptake rates, along with siderophore concentrations and biosynthesis potential at Station ALOHA across time (2013–2016) and depth (surface to 500 m) to observe changes in iron acquisition and internal cycling by the microbial community. The genetic potential for siderophore biosynthesis was widespread throughout the upper water column, and biosynthetic gene clusters peaked in spring and summer along with siderophore concentrations, suggesting changes in nutrient delivery, primary production, and carbon export seasonally impact iron acquisition. Dissolved iron turnover times, calculated from iron‐amended experiments in surface (15 m) and mesopelagic (300 m) waters, ranged from 9 to 252 d. The shortest average turnover times at both depths were associated with inorganic iron additions (14 9 d) and the longest with iron bound to strong siderophores (148 225 d). Uptake rates of siderophore‐bound iron were faster in mesopelagic waters than in the surface, leading to high Fe : C uptake ratios of heterotrophic bacteria in the upper mesopelagic. The rapid cycling and high demand for iron at 300 m suggest differences in microbial metabolism and iron acquisition in the mesopelagic compared to surface waters. Together, changes in siderophore production and consumption over the seasonal cycle suggest organic carbon availability impacts iron cycling at Station ALOHA.

Determinants of Agricultural Land Fallowing in Kerala, India: Insights and Implications

Kerala's land use dynamics have undergone significant transformations, with increasing fallows emerged as a key concern amid changing land utilization patterns. The study explores key factors contributing to the fallowing of agricultural land in Kerala. The research was conducted across three districts selected based on implementation of fallow land development schemes representing the northern, central, and southern regions of the state. A total of 360 farmers were surveyed, comprising 180 farmers with owned fallow land and 180 beneficiaries of fallow land development schemes. Data were collected using a pretested interview schedule, developed through extensive literature review and expert inputs. Factor analysis was employed to identify key determinants. Six major factors with eigenvalues greater than one were extracted, explaining 58.95% of the cumulative variance. These factors include perspectives on fallowing, socio-economic attributes, land use experience, risk contingencies, personal traits, and economic and agro-ecological features. The findings highlight that perspectives on fallowing contribute the largest variance (21.96%), emphasizing the importance of farmers' perception on causes and consequences of fallowing. Socio-economic attributes (11.25%) underline the role of family size, subsidiary enterprises, land value, and wage rate in influencing land use decisions. Land use experience (9.06%) reflects farming experience and preceding crop cultivated. Risk contingencies (6.22%) emphasize challenges like wild animal attacks and distance of farm land from road. Personal traits (5.50%) comprise of age and personal reason for fallowing. Economic and agro-ecological features (4.96%) including income, extreme weather events and land fragmentation, also emerged as critical determinants. The study provides a comprehensive understanding of the multi-dimensional factors driving agricultural land fallowing in Kerala, offering insights for policymakers and stakeholders to design targeted interventions to promote sustainable land use.

Rubber additives and relevant oxidation products in groundwater in a central China region: Levels, influencing factors and exposure

This study investigated the presence of rubber additives and relevant oxidation products (RAROPs) in groundwater in central China's aboveground river region. Seven RAROPs were detected, and their levels in shallow groundwater showed a mild decreasing trend from the area near the Yellow River (Avg: 8.49 ng·L-1) to the area on the far bank of the Yellow River (Avg: 5.01 ng·L-1). In contrast, deep groundwater's RAROPs contents showed a dramatic decrease to only 0.26 ng·L-1. The dominant contaminant was found to be N-(1, 3-dimethylbutyl) -N′-phenyl -p-phenylenediamine (6PPD). The vicinity of the garages and car parks was often characterized as contamination hotspots. Correlation analyses further indicated that aquaculture was likely to be a potential pathway for shallow groundwater contaminant inputs. The amount of RAROPs intake by humans through groundwater is nearly 30 times different due to the imbalanced development between urban and rural areas. Children were the most vulnerable to RAROPs. Therefore, human activities (transportation, waste tire storage, water resource allocation and utilization patterns, diversion of Yellow River water to aquaculture ponds) may exacerbate RAROPs pollution in groundwater by leaching contaminants through the surface soil. These results are important for developing appropriate utilization and protection strategies for groundwater resources in developing countries.

Antimicrobial utilisation patterns between 2013 and 2022 in Canadian neonates born at less than 33 weeks gestation: a retrospective cohort study

Excessive antimicrobial exposure is associated with an increase in neonatal mortality, morbidities and adverse neurodevelopment. Canadian Neonatal Network has been promoting judicious antimicrobial use through the Evidence-based Practice for Improving Quality processes. Our objective was to evaluate the antimicrobial consumption among neonates in tertiary neonatal intensive care units (NICU) in Canada in the recent decade. This is a retrospective cohort study including data from very preterm infants (born at <33 weeks gestational age) admitted to all NICUs in Canada between January 1, 2013, and December 31, 2022. Nationwide antimicrobial utilization rate (AUR) benchmarking started in 2016, and quality improvement initiatives were continued in the subsequent years to promote judicious use of antimicrobials across the network. AUR is defined as the number of days with ≥1 antimicrobial divided by the total patient days (PD). Culture-proven sepsis refers to a neonate with positive culture of pathogens in blood and/or cerebrospinal fluid. The outcomes were evaluated during pre- (2013-2017) and post-intervention periods (2018-2022). Interrupted time-series analysis was used, and comparison of AUR calculated per each 3-month time block and the slope changes were conducted across the pre- and post-intervention periods regarding total patients and subgroups. A total of 41,253 infants were included, with 22,644 (55%) being male. The AUR was significantly lower among infants from the post- vs. those from the pre-intervention periods (152 vs. 184, p<0.0001). Among 35,670 infants without culture-proven sepsis or necrotizing enterocolitis≥Stage 2, AUR was significantly lower in the post-intervention group vs. the pre-intervention group (110 vs. 136, p<0.0001). Interrupted time-series showed significant reduction in AUR during both pre- and post-intervention periods among all infants with and without culture proven sepsis or necrotizing enterocolitis≥Stage 2 (all p<0.0001), as well as those born at <29 weeks gestational age. A comprehensive, network-wide quality improvement initiatives led to a significant and sustained reduction in antimicrobial use among preterm infants born at <33 weeks gestational age with and without culture-proven sepsis or necrotizing enterocolitis≥Stage2. This study was supported by the Canadian Institutes of Health Research Project Grant 2019 (201903PJT-420294-CA2-CAAA-245530), matched funding from the British Columbia Women's Health Foundation and start-up funding from the Women and Children's Health Research Institute, University of Alberta. The coordinating center in Toronto is funded by the Canadian Institutes of Health Research grant for the Canadian Preterm Birth Network (PBN 150642).

Awareness of Fluoride Toothpaste among Parents of Children and Adolescents

This study assessed parental knowledge and utilization patterns of fluoride containing dentifrices in the context of youth oral health promotion. A direct questionnaire was administered to 168 parents of young patients who attended the Pediatric Dental Clinic at Yonsei University Dental Hospital between March and May 2024. The findings indicated that while a significant majority (94.6%) of parents acknowledged the importance of fluoride in adult oral care products, their understanding of the potential adverse effects was limited. The study found that 84.5% of children used fluoride toothpaste and 96.4% of parents considered fluoride toothpaste essential for their children. However, a considerable proportion (40.5%) used low-fluoride formulations and many parents lacked awareness of the fluoride concentration (42.3%) and the appropriate dosage for their children (61.3%). Notably, paternal parents had a higher likelihood of being uninformed about fluoride content (24.7%, &lt;i&gt;p&lt;/i&gt; = 0.003) and the correct quantity of toothpaste (26.2%, &lt;i&gt;p&lt;/i&gt; &lt; 0.05) that children should use. These observations underscore the need for targeted education for fluoride-containing oral care products for parents. Precise guidelines on suitable fluoride toothpaste types and quantities tailored to the developmental stages in children are important for enhancing oral health outcomes in youth.

Objective: This study utilizes the Sehat Card Plus (SCP) programme's health insurance database in Khyber Pakhtunkhwa(KP) to assess demographic characteristics, healthcare utilization patterns, and disease profiles of beneficiaries. Additionally,it analyses processes related to claims, settlements with hospitals, and the financial expenditure of the programme.Methods: The study employed the programme's third-party managed Management Information System (MIS) to obtain asample of 100,029 beneficiary records from January 1st, 2021, to October 31st, 2022, across 10 designated study districts inKP province. After removing 5,642 duplicate records, the final dataset comprised 94,387 unique beneficiary records,subjected to descriptive statistical analysis.Results: Among women, 25,745 (50%) of admissions were in the 15-45 years age group, while 14,189 (33%) of maleadmissions were in the 60 and above age group. The hospital mortality rate was 5,200 (5.5%), with an average cost peradmission of PKR 31,395. KP government spent PKR 2.96 billion on 94,387 patients, allocating PKR 828 million to treatcardiovascular diseases. The average cost of treating ischaemic heart disease was PKR 89,919. Empanelled hospitals tookan average of 51±52.8 days to send claims, and SLIC took 21±26.1 days to settle claims.Conclusion: The third party administrators of the SCP programme maintain a robust database, capturing all hospitaladmissions under the SCP programme. However, improvements in database quality and the incorporation of new indicatorsare recommended for enhanced and independent programme monitoring and evaluation, especially with regard to equity.Keywords: Health Insurance Database, Healthcare Utilization, Health Insurance Program Evaluation

Inpatient Test Utilization and Test Volume Benchmarking: A Q-Probes Study.

Test-ordering practices vary widely between and within health care organizations, and methods used to benchmark test utilization data are unstandardized. To develop and apply standardized methodology to compare inpatient test utilization data submitted by laboratories enrolled in a College of American Pathologists Q-Probes study. Participating laboratories provided inpatient test volumes for 50 designated analytes and total inpatient days for 2019 or a recent 12-month period. Test utilization patterns were characterized by studying test volumes standardized per 1000 inpatient days. Test volume variability used the standardized median absolute deviation; standardized test volumes were evaluated by calculating comparative ranges for each analyte. Standardized test volumes falling outside their respective comparative ranges are referred to as outliers in this study. Volume data were tested for association with stewardship practices and institutional demographics. Methodology using standardized test volume data identified test groups that are commonly used in the inpatient setting and efficiently identified volume outliers. High test volume outliers included creatine kinase myocardial band, free prostate-specific antigen, myoglobin, serotonin release assay, and hepatitis B serologies; no low-volume outliers were observed. Among 33 participants, 13 (39%) had no test volume outliers, while 5 (15%) showed multiple tests (13-34) with comparatively high volumes. No statistically significant relationships were found between stewardship practices and test-ordering patterns. Our approach can be used to measure inpatient test volume data across organizations and for identifying test volumes falling outside of the standardized comparative ranges that may require interventions to change test utilization practices.
