Generalizing observational study results: applying propensity score methods to complex surveys

Metabolic syndrome in the setting of obesity: impact on in-hospital complications and outcomes after total knee and hip arthroplasty

Aims

This study aims to evaluate the impact of metabolic syndrome in the setting of obesity on in-hospital outcomes and resource use after total joint replacement (TJR).

Methods

A retrospective analysis was conducted using the National Inpatient Sample from 2006 to the third quarter of 2015. Discharges representing patients aged 40 years and older with obesity (BMI > 30 kg/m2) who underwent primary TJR were included. Patients were stratified into two groups with and without metabolic syndrome. The inverse probability of treatment weighting (IPTW) method was used to balance covariates.

Results

The obese cohort with metabolic syndrome was significantly older, more likely to be female, had higher rates of Medicare insurance, and more likely to be non-Hispanic Black than the obese cohort without metabolic syndrome. In the unweighted analysis, patients with obesity and metabolic syndrome were more likely to experience cardiac, gastrointestinal, genitourinary, and postoperative anemia complications, had a longer length of stay, and were less likely to be discharged home compared to obese patients without metabolic syndrome. After adjusting for covariates using IPTW, patients with obesity and metabolic syndrome were more likely to experience postoperative anemia complications only and had lower rates of home discharge, but there were no significant differences in any other complication variables or length of stay.

Conclusion

Given the variability of metabolic health in obesity, the development of tailored perioperative protocols and recommendations acknowledging this variability in metabolic health in obese patients would ultimately potentially benefit patients and improve outcomes of TJR.

Application of High-Dimensional Propensity Score Methods to the National Health and Aging Trends Study

BACKGROUND

High-dimensional propensity scoring (HDPS) is a method for empirically identifying potential confounders within large healthcare databases such as administrative claims data. However, this method has not yet been applied to large national health surveys such as the National Health and Aging Trends Study (NHATS), an ongoing nationally representative survey of older adults in the United States and important resource in gerontology research.

METHODS

In this Research Practice article, we present an overview of HDPS and describe the specific data transformation steps and analytic considerations needed to apply it to national health surveys. We applied HDPS within NHATS to investigate the association between self-reported visual difficulty and incident dementia, comparing HDPS to conventional confounder selection methods.

RESULTS

Among 7 207 dementia-free NHATS Wave 1 respondents, 528 (7.3%) had self-reported visual difficulty. In an unadjusted discrete time proportional hazards model accounting for the complex survey design of NHATS, self-reported visual difficulty was strongly associated with incident dementia (odds ratio [OR] 2.34, 95% confidence interval [CI]: 1.95-2.81). After adjustment for standard investigator-selected covariates via inverse probability weighting, the magnitude of this association decreased, but evidence of an association remained (OR 1.44, 95% CI: 1.11-1.85). Adding 75 HDPS-prioritized variables to the investigator-selected propensity score model resulted in further attenuation of the association between visual impairment and dementia (OR 0.94, 95% CI: 0.70-1.23).

CONCLUSIONS

HDPS can be successfully applied to national health surveys such as NHATS and may improve confounder adjustment. We hope developing this framework will encourage future consideration of HDPS in this setting.

Analysis of patients with Crohn's disease and intestinal obstruction: a National Inpatient Sample study

Background

Crohn's disease (CD) predisposes patients to intestinal obstruction (IO), a severe complication. This study examined the outcomes and healthcare utilization of patients with CD and IO using data from the National Inpatient Sample (NIS).

Methods

This retrospective analysis of NIS data from 2016-2020 compared hospitalized adult CD patients with and without IO. Outcomes studied include in-hospital mortality, length of stay (LOS), hospitalization charges, and the requirement for intervention, using regression models for adjustment.

Results

Among the 304,149 CD patients, 27,024 had IO. These patients experienced higher in-hospital mortality (3.9% vs. 1.8% for non-IO, adjusted odds ratio [aOR] 1.78, 95% confidence interval [CI] 1.09-2.89; P=0.02), longer mean LOS (7.23 vs. 4.53 days for non-IO, P<0.001), and higher average hospitalization charges ($71,775 vs. $43,717 for non-IO, P<0.001). Additionally, they had higher odds of requiring admission to the intensive care unit (aOR 1.99, 95%CI 1.45-2.73; P<0.001), intubation (aOR 2.53, 95%CI 1.74-3.68; P<0.001), balloon dilation (aOR 1.50, 95%CI 1.132-1.98; P=0.005), or intestinal resection (aOR 2.29, 95%CI 2.11-2.49; P<0.001).

Conclusions

CD patients with IO face considerable challenges, including greater mortality, longer hospital stays, and higher hospitalization costs. The need for intensive care and surgical interventions highlights the urgent need for improved management and treatment strategies to enhance outcomes for these patients.

Intravascular Ultrasound during Endovascular Intervention for Peripheral Artery Disease, by Severity, Location, Device, and Procedure

There is limited evidence for the role of intravascular ultrasound (IVUS) in patients who underwent peripheral vascular intervention (PVI). We conducted retrospective cohort study utilizing the Healthcare Cost and Utilization Project-Agency for Healthcare Research and Quality National Readmission database to delineate outcomes in IVUS-guided PVI versus non-IVUS-guided PVI. The present study utilized National Readmission database between January 1, 2016, and December 31, 2019. We identified patients who underwent endovascular intervention for peripheral artery disease using relevant International Classification of Diseases, Tenth Revision, Procedural Coding System. The cohort was divided based on the use of IVUS during the procedure. The primary outcome was major amputation at 6 months after index hospitalization. Measured confounders were matched using propensity score inverse probability of treatment weighing method. We further performed a subgroup analysis based on disease severity, location of intervention, device, and procedure. A total of 434,901 hospitalizations were included in the present analysis. PVI with IVUS compared with no IVUS had similar risk of amputation at 6 months (195 of 8,939 [2.17%] vs 10,404 of 384,003 [2.71%]), hazard ratio 0.98, CI 0.77 to 1.25. Further, there was no difference in the rates of secondary outcomes. On subgroup analysis, amputation rates were significantly lower in patients with rest pain, in iliac intervention, or patients who underwent drug-eluting stent implantation with the use of IVUS compared with no IVUS. This nationwide observational study showed that there was no difference in major amputation rates with the use of IVUS in patients who underwent PVI. However, in subgroup of patients with rest pain, iliac intervention or drug-eluting stent implantation IVUS use was associated with significantly lower major amputation rates.

Associations between mental health & substance use treatment and alcohol use progression and recovery among US women drinkers

BACKGROUND

Alcohol use has profound public health impact on women; however, modifiable factors that may influence alcohol use progression/recovery, including health service utilization, are understudied in women.

OBJECTIVE

To investigate the association between mental health (MH) and substance use (SU) treatment with alcohol use progression and recovery among women who currently use alcohol or have in the past.

METHODS

This study is a secondary data analysis of prospective data from waves 1 (2001-2002) and 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; a US-nationally representative sample of adults). The analytic sample was limited to women who reported past or current alcohol use at wave 1 (N = 15,515). Latent transition analysis (LTA) examined whether receiving SU/MH treatment in the year prior to wave 1 was associated with transitioning between three empirically-derived stages of alcohol involvement (no, moderate, and severe problems classes), between Waves 1 and 2 adjusting for possible confounders using propensity score weight.

RESULTS

Compared to White female drinkers, female drinkers who were from Black, Hispanic, or other races were less likely to receive SU/MH treatment (p-values ≤. 001). SU/MH treatment in the year prior to wave 1 was associated with transitioning from the moderate problems class to the no problems class between Waves 1 and 2 (p-value = .04).

CONCLUSION

Receipt of SU or MH treatment among women, was associated with a higher likelihood of remission from moderate alcohol use problems to no problems over time. Future research, including investigation into treatment characteristics (e.g., frequency, duration, type) should further explore why women initially experiencing severe alcohol use problems did not experience similar remission.

Association of Medicare Advantage Enrollment With Financial Burden of Care : A Retrospective Cohort Study

BACKGROUND

Compared with traditional Medicare (TM), Medicare Advantage (MA) plans typically offer supplemental benefits and lower copayments for in-network services and must include an out-of-pocket spending limit.

OBJECTIVE

To examine whether the financial burden of care decreased for persons switching from TM to MA (TM-to-MA switchers) relative to those remaining in TM (TM stayers).

DESIGN

Retrospective longitudinal cohort study comparing changes in financial outcomes between TM-to-MA switchers and TM stayers.

SETTING

Population-based.

PARTICIPANTS

7054 TM stayers and 1544 TM-to-MA switchers from the Medical Expenditure Panel Survey, 2014 to 2021.

MEASUREMENTS

Individual health care costs (out-of-pocket spending and cost sharing), financial burden (high and catastrophic), and subjective financial hardship (difficulty paying medical bills, paying medical bills over time, and inability to pay medical bills).

RESULTS

Compared with TM stayers, TM-to-MA switchers had small differences in out-of-pocket spending ($168 [95% CI, -$133 to $469]) and proportions of total health expenses paid out of pocket (cost sharing) (0.2 percentage point [CI, -1.3 to 1.7 percentage points]), families with out-of-pocket spending greater than 20% of their income (high financial burden) (0.3 percentage point [CI, -2.5 to 3.0 percentage points]), families reporting out-of-pocket spending greater than 40% of their income (catastrophic financial burden) (0.7 percentage point [CI, -0.1 to 1.6 percentage points]), families reporting paying medical bills over time (-0.2 percentage point [CI, -1.7 to 1.4 percentage points]), families having problems paying medical bills (-0.4 percentage point [CI, -2.7 to 1.8 percentage points]), and families reporting being unable to pay medical bills (0.4 percentage point [CI, -1.3 to 2.0 percentage points]).

LIMITATION

Inability to account for all medical care and cost needs and variations across MA plans, small baseline differences in out-of-pocket spending, and potential residual confounding.

CONCLUSION

Differences in financial outcomes between beneficiaries who switched from TM to MA and those who stayed with TM were small. Differences in financial burden ranged across outcomes and did not have a consistent pattern.

Identifying Vulnerabilities to NSAID Adverse Events in the U.S. Population: An Analysis of Preexisting Conditions and Sex

Purpose: In 2005, the Food and Drug Administration (FDA) issued a decision memorandum regarding nonsteroidal anti-inflammatory drugs (NSAIDs). The memorandum recommended the withdrawal of certain NSAIDs due to potential cardiovascular adverse effects. It highlighted the issue of cardiovascular risk associated with NSAIDs as a class. The NSAID medication guide includes a wide range of adverse drug reactions (ADRs), such as increased blood pressure, liver failure, allergic reactions, heart attack, and intestinal bleeding. Although both sexes have an increased risk of ADRs with NSAID use, females have a greater risk than males due to differences in pharmacodynamics and higher medication concentrations (mg/kg). In particular, females with high blood pressure, coronary heart, kidney, and liver disease are at an additional risk of harm from NSAID ADRs. This study quantifies sex-specific differences and other factors associated with prescription NSAID use. Method: The data for this study were obtained from the National Health and Nutrition Examination Survey (NHANES), a complex survey conducted by the Centers for Disease Control and Prevention (CDC) in two-year cycles. A survey-weighted logistic regression model was utilized to investigate potential sex differences with prescription NSAIDs in the context of other factors, including kidney disease, hypertension, liver disease, insurance status, coronary heart disease, and age, within the 2011-2018 NHANES survey data. Results: Females reported a slightly higher percentage of high blood pressure and kidney disease than males, while males reported a slightly higher percentage of coronary heart and liver disease than females. Last, the model indicated that females were 58% more likely to have used a prescription NSAID than males. Conclusion: The results confirm that women and people with medical conditions, who would potentially suffer greater harm from NSAID ADRs, are more likely to use a prescription NSAID than individuals without these conditions.

Sex differences in heart disease prevalence among individuals with spinal cord injury: A population-based study

CONTEXT/OBJECTIVE

The risk for cardiovascular disease is amplified following spinal cord injury, but whether risk differs between the sexes remains unknown. Here, we evaluated sex differences in the prevalence of heart disease among individuals with spinal cord injury, and compared sex differences with able-bodied individuals.

DESIGN

The design was a cross-sectional study. Multivariable logistic regression analysis was conducted, using inverse probability weighting to account for the sampling method and to adjust for confounders.

SETTING

Canada.

PARTICIPANTS

Individuals who participated in the national Canadian Community Health Survey.

INTERVENTIONS

Not applicable.

OUTCOME MEASURES

Self-reported heart disease.

RESULTS

Among 354 individuals with spinal cord injury, the weighted prevalence of self-reported heart disease was 22.9% in males and 8.7% in females, with an inverse-probability weighted odds ratio of 3.44 (95% CI 1.70-6.95) for males versus females. Among 60,605 able-bodied individuals, the prevalence of self-reported heart disease was 5.8% in males and 4.0% in females, with an inverse probability weighted odds ratio of 1.62 (95% CI 1.50-1.75) for males versus females. The effect of male sex on increasing heart disease prevalence was about two times higher among individuals with spinal cord injury than able-bodied individuals (relative difference in inverse probability weighted odds ratios = 2.12, 95% CI 1.08-4.51).

CONCLUSION

Males with spinal cord injury exhibit a significantly higher prevalence of heart disease, compared with females with spinal cord injury. Moreover, relative to able-bodied individuals, spinal cord injury amplifies sex-related differences in heart disease. Overall, this work will inform targeted cardiovascular prevention strategies, and may also inform a better understanding of cardiovascular disease progression in both able-bodied and individuals with spinal cord injury.

Recruitment, data collection, participation rate, and representativeness of the international cross-sectional PRICOV-19 study across 38 countries

BACKGROUND

Recruitment for surveys has been a great challenge, especially in general practice.

METHODS

Here, we reported recruitment strategies, data collection, participation rates (PR) and representativeness of the PRICOV-19 study, an international comparative, cross-sectional, online survey among general practices (GP practices) in 37 European countries and Israel.

RESULTS

Nine (24%) countries reported a published invitation; 19 (50%) had direct contact with all GPs/GP practices; 19 (50%) contacted a sample of GPs /GP practices; and 7 (18%) used another invitation strategy. The median participation rate was 22% (IQR = 10%, 28%). Multiple invitation strategies (P-value 0.93) and multiple strategies to increase PR (P-value 0.64) were not correlated with the PR. GP practices in (semi-) rural areas, GP practices serving more than 10,000 patients, and group practices were over-represented (P-value < 0.001). There was no significant correlation between the PR and strength of the primary care (PC) system [Spearman's r 0.13, 95% CI (-0.24, 0.46); P-value 0.49]; the COVID-19 morbidity [Spearman's r 0.19, 95% CI (-0.14, 0.49); P-value 0.24], or COVID-19 mortality [Spearman's r 0.19, 95% CI (-0.02, 0.58); P-value 0.06] during the three months before country-specific study commencement.

CONCLUSION

Our main contribution here was to describe the survey recruitment and representativeness of PRICOV-19, an important and novel study.

Association of metabolic syndrome and its components with Parkinson's disease: a cross-sectional study

BACKGROUND

The interrelation between metabolic syndrome (MetS) and Parkinson's disease (PD) likely arises from shared pathological mechanisms. This study thus aims to examine the impact of MetS and its components on PD.

METHODS

This study utilized data extracted from the National Health and Nutrition Examination Survey database spanning 1999 to 2020. The random forest algorithm was applied to fill in the missing data. Propensity score optimal full matching was conducted. The data were adjusted by total weights derived from both sampling and matching weights. The weighted data were utilized to create multifactor logistic regression models. Odds ratios (ORs) and average marginal effects, along with their corresponding 95% confidence intervals (CIs), were calculated.

RESULTS

MetS did not significantly affect the risk of PD (OR: 1.01; 95% CI: 0.77, 1.34; P = 0.92). Hypertension elevated the risk of PD (OR: 1.33; 95% CI: 1.01, 1.76; P = 0.045), accompanied by a 0.26% increased probability of PD occurrence (95% CI: 0.01%, 0.52%; P = 0.04). Diabetes mellitus (DM) had a 1.38 times greater likelihood of developing PD (OR:1.38; 95% CI: 1.004, 1.89; P = 0.046), corresponding to a 0.32% increased probability of PD occurrence (95% CI: -0.03%, 0.67%; P = 0.07). Nevertheless, no correlation was observed between hyperlipidemia, waist circumference and PD.

CONCLUSION

MetS does not affect PD; however, hypertension and DM significantly increase the risk of PD.

Sampling weighting strategies in causal mediation analysis

BACKGROUND

Causal mediation analysis plays a crucial role in examining causal effects and causal mechanisms. Yet, limited work has taken into consideration the use of sampling weights in causal mediation analysis. In this study, we compared different strategies of incorporating sampling weights into causal mediation analysis.

METHODS

We conducted a simulation study to assess 4 different sampling weighting strategies-1) not using sampling weights, 2) incorporating sampling weights into mediation "cross-world" weights, 3) using sampling weights when estimating the outcome model, and 4) using sampling weights in both stages. We generated 8 simulated population scenarios comprising an exposure (A), an outcome (Y), a mediator (M), and six covariates (C), all of which were binary. The data were generated so that the true model of A given C and the true model of A given M and C were both logit models. We crossed these 8 population scenarios with 4 different sampling methods to obtain 32 total simulation conditions. For each simulation condition, we assessed the performance of 4 sampling weighting strategies when calculating sample-based estimates of the total, direct, and indirect effects. We also applied the four sampling weighting strategies to a case study using data from the National Survey on Drug Use and Health (NSDUH).

RESULTS

Using sampling weights in both stages (mediation weight estimation and outcome models) had the lowest bias under most simulation conditions examined. Using sampling weights in only one stage led to greater bias for multiple simulation conditions.

DISCUSSION

Using sampling weights in both stages is an effective approach to reduce bias in causal mediation analyses under a variety of conditions regarding the structure of the population data and sampling methods.

Vegetarian diets and risk of nonalcoholic fatty liver disease: An observational study of National Health and Nutrition Examination Survey 2005-2018 using propensity score methods

BACKGROUND

Studies on the association between vegetarian diets and nonalcoholic fatty liver disease (NAFLD) are limited and have inconsistent results. This study aims to explore the association between vegetarian diets and NAFLD and compare the stage of fibrosis between vegetarians and nonvegetarians in a US representative sample.

METHODS

Cross-sectional data from 23,130 participants aged ≥20 years were obtained from the National Health and Nutrition Examination Survey, 2005-2018. Vegetarian status was classified based on two 24-h dietary recalls. We examined the association between vegetarian diets and the risk of NAFLD using the propensity score weighting method.

RESULTS

Vegetarian diets were significantly associated with decreases in hepatic steatosis index (HSI), US fatty liver index and nonalcoholic fatty liver disease fibrosis score with mean differences of -2.70 (95% confidence interval [CI]: -3.69, -1.70), -3.03 (95% CI: -7.15, -0.91) and -0.12 (95% CI: -0.26, -0.01), respectively. While modelling the risk of NAFLD, we estimated that vegetarians were 53% less likely to have NAFLD assessed by HSI (odds ratios [OR]: 0.47; 95% CI: 0.34, 0.65). The effect of vegetarian diets was higher among individuals with lower waist circumferences (OR: 0.20) than among those with higher waist circumferences (OR: 0.53,p interaction ${p}_{\text{interaction}}\,$ = 0.004). However, the association was largely attenuated after adjusting for body mass index and diabetes status. No significant association was identified between vegetarian diets and advanced fibrosis.

CONCLUSIONS

Vegetarian diets were associated with a lower prevalence of NAFLD among US adults, and the association appeared to be stronger in people with lower waist circumferences. Further studies are warranted to replicate our findings.

Association of waist circumference and BMI with premature death in young and middle-aged population

Introduction

Premature death is a global health indicator, significantly impacted by obesity, especially in young and middle-aged population. Both body mass index (BMI) and waist circumference (WC) assess obesity, with WC specifically indicating central obesity and showing a stronger relationship with mortality. However, despite known associations between BMI and premature death, as well as the well-recognized correlation between WC and adverse health outcomes, the specific relationship between WC and premature death remains unclear. Therefore, focusing on young and middle-aged individuals, this study aimed to reliably estimate independent and combined associations between WC, BMI and premature death, thereby providing causal evidence to support strategies for obesity management.

Methods

This study involved 49,217 subjects aged 18-50 years in the United States from 1999 to 2018 National Health and Nutrition Examination Survey (NHANES). Independent and combined associations between WC and BMI with premature death across sex and age stratum were examined by Cox regression. Survey weighting and inverse probability weighting (IPW) were further considered to control selection and confounding bias. Robustness assessment has been conducted on both NHANES and China Health and Retirement Longitudinal Study (CHARLS) data.

Results

A linear and positive relationship between WC and all-cause premature death was found in both males and females, with adjusted HRs of 1.019 (95%CI = 1.004-1.034) and 1.065 (95%CI = 1.039-1.091), respectively. Nonlinear relationships were found with respect to BMI and all-cause premature death. For females aged 36-50 with a BMI below 28.6 kg/m2, the risk of premature death decreased as BMI increased, indicated by adjusted HRs of 0.856 (95%CI = 0.790-0.927). Joint analysis showed among people living with obesity, a larger WC increased premature death risk (HR = 1.924, 95%CI = 1.444-2.564).

Discussion

WC and BMI exhibited prominent associations with premature death in young and middle-aged population. Maintaining an appropriate WC and BMI bears significant implications for preventing premature death.

Outcomes of transcatheter aortic valve replacement in patients with history of chest wall irradiation: Propensity matched analysis of five years data from national inpatient sample (2016-2020)

INTRODUCTION

Chest radiotherapy has been utilized to treat intra-thoracic and mediastinal tumors. Chest wall irradiation (C-XRT) survivors frequently develop valvular disease, including aortic stenosis, which eventually requires valve replacement. Previous trials have shown worse outcomes with surgical aortic valve replacement. However, transcatheter aortic valve replacement (TAVR) outcomes-related data in patients with C-XRT is limited.

METHODS

The national inpatient sample (NIS) database was queried from 2016 to 2020 to identify adult hospitalizations with TAVR, which were dichotomized based on a history of C-XRT using ICD-10-CM codes. Propensity score matching was performed to derive age, sex, hospital characteristics, and co-morbidities matched controls without a history of C-XRT. The outcomes studied were inpatient mortality and complications, mean length of stay (LOS), and total hospital charge (THC). Multivariate logistic and linear regression were used to analyze the outcomes.

RESULTS

Of 296,670 patients who underwent TAVR between 2016 and 2020, 515 had a history of C-XRT. Upon propensity score matching in patients undergoing TAVR, Patients with a history of C-XRT showed significantly lower adjusted odds of in-hospital mortality (adjusted odd ratio [aOR] 0.04, 95 % CI [0.003-0.57], p = 0.017), lower mean LOS by 1.6 days (-1.88 to -1.26 days, p < 0.001) and reduced mean THC (-$74,720, [-$88,784 to -$60,655], p < 0.001). Additionally, patients with C-XRT had significantly lower adjusted odds of inpatient complications, mainly acute myocardial infarction, cerebrovascular events, acute respiratory failure, acute kidney injury, need for vasopressors and cardiopulmonary resuscitation, whereas similar odds of complications, including a requirement of intubation, mechanical ventilation, hemodialysis, and cardiogenic shock.

CONCLUSION

Our analysis showed reduced adjusted odds of in-hospital mortality, length of stay, total hospital charges, and inpatient complications in patients undergoing TAVR with a history of C-XRT. TAVR appears to be a safe and viable alternative in this population subgroup.

Frailty Among Revision Total Knee Arthroplasty Recipients: Epidemiology and Propensity Score-weighted Analysis of Effect on In-hospital Postoperative Outcomes

BACKGROUND

Frailty has been shown to correlate with worse outcomes after total knee arthroplasty (TKA), although less is known regarding its effect on revision TKA (rTKA). This study examines the epidemiologic characteristics and inpatient outcomes of patients with frailty undergoing rTKA.

METHODS

Discharge data from National Inpatient Sample registry were used to identify all patients aged 50 years or older who underwent rTKA between 2006 and 2015. Patients were stratified into frail and nonfrail groupings, based on the presence of specific International Classification of Diseases-9 diagnostic coding. An analysis comparing the epidemiology, medical comorbidities, and propensity score-weighted postoperative clinical and economic outcomes of the two groups was done.

RESULTS

From 2006 to the third quarter of 2015, a total of 576,920 patients (17,727 frail) who underwent rTKA were included. The average age in the study's population was 67.2 years, with a female distribution of 57.4%. Frail patients were more likely to exhibit markedly higher rates of almost all modified Elixhauser Comorbities than their nonfrail counterparts. Frail patients were also more likely to undergo different types of revisions, including an increased rate of removal of the prosthesis without replacement. In addition, frail patients displayed increased likelihood of experiencing any postoperative complication, deep vein thrombosis, postoperative anemia, respiratory complications, and wound dehiscence. Frail patients experienced lower rates of discharge home and increased length of stay than the nonfrail cohort.

DISCUSSION

Patients with frailty undergoing rTKA are at markedly higher risk for inpatient postoperative complications and increased length of stay. Understanding the implications of frailty within rTKA is essential for risk assessment and preoperative optimization for this expanding population.

Breast cancer screening among Medicare Advantage enrollees with dementia

BACKGROUND

The decision to screen for breast cancer among older adults with dementia is complex and must often be individualized, as these individuals have an elevated risk of harm from over-screening. Medicare beneficiaries with dementia are increasingly enrolling in Medicare Advantage plans, which typically promote receipt of preventive cancer screening among their enrollees. This study examined the utilization of breast cancer screening among Medicare enrollees with dementia, in Medicare Advantage and in fee-for-service Medicare.

METHODS

We conducted a pooled cross-sectional study of women with Alzheimer's disease and related dementias or cognitive impairment who were eligible for mammogram screening. We used Medicare Current Beneficiary Survey data to identify utilization of biennial mammogram screening between 2012 and 2019. Poisson regression models were used to estimate prevalence ratios of mammogram utilization and to calculate adjusted mammogram rates for Medicare Advantage and fee-for-service Medicare enrollees with dementia, and further stratified by rurality and by dual eligibility for Medicare and Medicaid.

RESULTS

Mammogram utilization was 16% higher (Prevalence Ratio [PR] 1.16; 95% CI: 1.05, 1.29) among Medicare Advantage enrollees with dementia, compared to their counterparts in fee-for-service Medicare. Rural enrollees experienced no significant difference (PR 0.99; 95% CI: 0.72, 1.37) in mammogram use between Medicare Advantage and fee-for-service Medicare enrollees. Among urban enrollees, Medicare Advantage enrollment was associated with a 21% higher mammogram rate (PR 1.21; 95% CI: 1.09, 1.35). Dual-eligible Medicare Advantage enrollees had a 34% higher mammogram rate (PR 1.34; 95% CI: 1.10, 1.63) than dual-eligible fee-for-service Medicare enrollees. Among non-dual-eligible enrollees, adjusted mammogram rates were not significantly different (PR 1.11; 95% CI: 0.99, 1.24) between Medicare Advantage and fee-for-service Medicare enrollees.

CONCLUSIONS

Medicare beneficiaries age 65-74 with Alzheimer's disease and related dementias or cognitive impairment had a higher mammogram use rate when they were enrolled in Medicare Advantage plans compared to fee-for-service Medicare, especially when they were dual-eligible or lived in urban areas. However, some Medicare Advantage enrollees with Alzheimer's disease and related dementias or cognitive impairment may have experienced over-screening for breast cancer.

The Effect of Home- and Community-Based Services on Social Engagement

Objectives: Home- and community-based services (HCBS) help older adults to remain active in community settings. However, it is not known if there is a causal relationship between HCBS and social engagement. Methods: We used data from the 2010 and 2012 Health and Retirement Study and measured the effect of HCBS on social engagement via nearest-neighbor Mahalanobis matching, optimal pair matching, genetic matching, and optimal full matching. Results: Genetic matching showed that the odds of social engagement for participants who received at least one HCBS (congregate meal, home-delivered meal, transportation service, case management, homemaker or housekeeping services, or caregiver services) in the prior two years was 1.07 times more likely than participants who have not received any HCBS (robust SE = .030, p = .040). Discussion: HCBS may remove barriers to social engagement through increasing older adults' personal resources and personal networks.

Medicaid compared to private insurance is associated with lower rates of sterilization in people with unwanted births

BACKGROUND

Medicaid, unlike any other insurance mechanism, imposes a consent requirement on female patients desiring sterilization that must be completed at least 30 days, but no more than 180 days, before sterilization. Desired sterilization cannot be completed in the Medicaid population without this consent. Large-scale national evidence is lacking on the effect of this requirement.

OBJECTIVE

This study aimed to explore the influence of insurance status on the achievement of postpartum sterilization after a self-reported unwanted birth in a nationally representative sample.

STUDY DESIGN

This was a retrospective cohort analysis using data from the 2013-2015 National Survey of Family Growth. The National Survey of Family Growth uses a stratified, multistage clustered sample to make nationally representative estimates for men and women aged 15 to 44 years in the household population of the United States. The analysis was limited to a cohort of birthing people who reported their last birth as unwanted and who were insured by either Medicaid or private insurance. The survey was analyzed with the application of inverse probability of treatment weights to balance those with Medicaid and those with private insurance in addition to the survey weight. The association between completion of postpartum sterilization and insurance type was evaluated using weighted logistic regression, adjusting for demographic and clinical characteristics.

RESULTS

In an adjusted and inverse probability of treatment weight balanced analysis of a weighted national sample representing 4,164,304 people (416 respondents), Medicaid-insured birthing people with history of unwanted births were found to have 56% lower odds of obtaining postpartum sterilization (odds ratio, 0.44; 95% confidence interval, 0.22-0.87; P=.019) than those with private insurance.

CONCLUSION

This study adds to mounting evidence that insurance type plays a significant role in the achievement of desired postpartum sterilization, with individuals with Medicaid less likely to undergo the procedure. The findings call for policy reforms around sterilization policy in the United States, emphasizing the need for uniform consent procedures that do not discriminate based on insurance status.

Impact of Advanced Therapy Centers on Characteristics and Outcomes of Heart Failure Admissions

BACKGROUND

Although much attention has been paid to admission and transfer patterns for cardiogenic shock, contemporary data are lacking on decompensated heart failure (HF) admissions and transfers and the impact of advanced therapy centers (ATCs) on outcomes.

METHODS

HF hospitalizations were obtained from the Nationwide Readmissions Database 2016 to 2019. Centers performing at least 1 heart transplant or left ventricular assist device were classified as ATCs. Patient characteristics, outcomes, and procedural volume were compared among 3 cohorts: admissions to non-ATCs, admissions to ATCs, and transfers to ATCs. A secondary analysis evaluated outcomes for severe HF hospitalizations (cardiogenic shock, cardiac arrest, and mechanical ventilation). Multivariable logistic regression was performed to adjust for the presence of HF decompensations and significant clinical variables during univariate analysis.

RESULTS

A total of 2 331 690 hospitalizations (81.2%) were admissions to non-ATCs (94.5% of centers), 525 037 (18.3%) were admissions to ATCs (5.5% of centers), and 15 541 (0.5%) were transferred to ATCs. Patients treated at ATCs (especially those transferred) had higher rates of HF decompensations, procedural frequency, lengths of stay, and costs. Unadjusted mortality was 2.6% at non-ATCs and was higher at ATCs, both for directly admitted (2.9%, P<0.001) and transferred (11.2%, P<0.001) patients. However, multivariable-adjusted mortality was significantly lower at ATCs, both for directly admitted (odds ratio, 0.82 [95% CI, 0.78-0.87]; P<0.001) and transferred (odds ratio, 0.66 [95% CI, 0.57-0.78]; P<0.001) patients. For severe HF admissions, unadjusted mortality was 37.2% at non-ATCs and was lower at ATCs, both for directly admitted (25.3%, P<0.001) and transferred (25.2%, P<0.001) patients, with similarly lower multivariable-adjusted mortality.

CONCLUSIONS

Patients with HF treated at ATCs were sicker but associated with higher procedural volume and lower adjusted mortality.

Are disparities in mental health care for Medicaid beneficiaries lower in managed care?

BACKGROUND

There are large and persistent racial and ethnic disparities in the use of mental health care in the United States. Medicaid managed care plans have the potential to reduce racial and ethnic disparities in use of mental health care through monitoring of need and active management of use of services across the populations they cover. This study compares racial and ethnic disparities among Medicaid beneficiaries in managed care with those not in managed care.

METHODS

We compared Medicaid beneficiaries enrolled health maintenance organizations (HMOs) with those in fee-for-service (FFS) using data from the 2007-2015 Medical Expenditure Panel Survey (N = 26,113). We specified two-part propensity score adjusted models to estimate differences in mental health related emergency department visits, hospital stays, prescription fills, and outpatient visits overall and by race/ethnicity.

RESULTS

HMO enrollment was associated with lower odds of having a mental health prescription (OR = 0.86, 95 % CI 0.78-0.96) or outpatient visit (OR = 0.82 95 % CI 0.73-0.92). These differences were similar across racial and ethnic groups or larger among Non-Hispanic Black and Hispanic beneficiaries than among Non-Hispanic White beneficiaries.

CONCLUSIONS

Medicaid managed care has not improved the inequitable allocation of mental health care across racial and ethnic groups. Explicit attention to monitoring of racial and ethnic differences in use of mental health care in Medicaid managed care is warranted.

IMPLICATIONS

Improvement in racial and ethnic disparities in mental health care in Medicaid manage care is unlikely to occur without targeted accountability mechanisms, such as required reporting or other contracting requirements.

Application of inverse weighting analysis to assess the association of youth perceptions with the age of initiation of tobacco products

Introduction

To examine if perceptions of harmfulness and addictiveness of hookah and cigarettes impact the age of initiation of hookah and cigarettes, respectively, among US youth. Youth (12-17 years old) users and never users of hookah and cigarettes during their first wave of PATH participation were analyzed by each tobacco product (TP) independently. The effect of perceptions of (i) harmfulness and (ii) addictiveness at the first wave of PATH participation on the age of initiation of ever use of hookah was estimated using interval-censoring Cox proportional hazards models.

Methods

Users and never users of hookah at their first wave of PATH participation were balanced by multiplying the sampling weight and the 100 balance repeated replicate weights with the inverse probability weight (IPW). The IPW was based on the probability of being a user in their first wave of PATH participation. A Fay's factor of 0.3 was included for variance estimation. Crude hazard ratios (HR) and 95% confidence intervals (CIs) are reported. A similar process was repeated for cigarettes.

Results

Compared to youth who perceived each TP as "a lot of harm", youth who reported perceived "some harm" had younger ages of initiation of these tobacco products, HR: 2.53 (95% CI: 2.87-4.34) for hookah and HR: 2.35 (95% CI: 2.10-2.62) for cigarettes. Similarly, youth who perceived each TP as "no/little harm" had an earlier age of initiation of these TPs compared to those who perceived them as "a lot of harm", with an HR: 2.23 (95% CI: 1.82, 2.71) for hookah and an HR: 1.85 (95% CI: 1.72, 1.98) for cigarettes. Compared to youth who reported each TP as "somewhat/very likely" as their perception of addictiveness, youth who reported "neither likely nor unlikely" and "very/somewhat unlikely" as their perception of addictiveness of hookah had an older age of initiation, with an HR: 0.75 (95% CI: 0.67-0.83) and an HR: 0.55 (95% CI: 0.47, 0.63) respectively.

Discussion

Perceptions of the harmfulness and addictiveness of these tobacco products (TPs) should be addressed in education campaigns for youth to prevent early ages of initiation of cigarettes and hookah.

Impact of chronic thrombocytopenia on healthcare resource utilization, in-hospital outcomes, and costs following percutaneous coronary intervention of chronic total occlusion: a nationwide propensity weighted analysis

BACKGROUND

Data on the impact of chronic thrombocytopenia (CT) on outcomes following chronic total occlusion (CTO) percutaneous coronary interventions (PCI) is limited. Most studies are case reports and focused on postprocedural thrombocytopenia. The purpose of this present study is to assess the impact of CT (> one year) on health resource utilization (HRU), in-hospital outcomes, and cost following CTO PCI.

METHODS

We used discharge data from the 2016-2018 National Inpatient Sample and propensity score-weighted approach to examine the association between CT and HRU among patients undergoing CTO PCI. HRU was measured as a binary indicator defined as a length of stay greater than seven days and/or discharge to a non-home setting. The cost was measured as total charges standardized to 2018 dollars. Both outcomes were assessed using generalized linear models adjusted for survey year, and baseline characteristics.

RESULTS

Relative to its absence, the presence of CT following CTO PCI was associated with a 4.8% increased probability of high HRU (Population Average Treatment Effect (PATE) estimate = 0.048; 95% Confidence Interval (CI) = 0.041-0.055; P<0.001) and approximately $18,000 more in total hospital charges (PATE estimate = +$18,297.98; 95% CI = $15,101.33-$21,494.63, P<0.001).

CONCLUSION

Among chronic total occlusion patients undergoing percutaneous coronary intervention, those with chronic thrombocytopenia had higher resource use, including total hospital charges, and worse in-hospital outcomes when compared with those without chronic thrombocytopenia.

Historical Obesity and Early-Onset Cancers: A Propensity-Weighted Analysis of the National Health and Nutrition Examination Survey

BACKGROUND

The incidence of early-onset obesity-related cancers (diagnosed < 50 years) is increasing in the U.S. We examined the reported historical body mass index (BMI) of adults with early and later-onset cancers to explore relation to obesity.

METHODS

We queried the 1999-2018 NHANES database for adults diagnosed with obesity-related cancers (colorectal, non-colorectal gastrointestinal, uterine, breast). We classified early and late-onset cancer based on a diagnosis age of < 50 and ≥ 50 years, respectively. Propensity-weighted analysis was used to compare prior historical BMIs between the matched groups.

RESULTS

After weighing, we included 2,966,528 patients with obesity-related cancers, 846,211 (28%) of which were < 50 years. In the matched analysis, 69.1% of early-onset CRC cases were diagnosed as obese (BMI ≥ 30 kg/m2) before cancer diagnosis, compared to 47.2% of late-onset cases (p < 0.03). Similarly, a higher percentage of adults with other early-onset gastrointestinal cancers had prior obesity as compared to the late-onset cohort (70.3% vs. 40.5%, p = 0.0002). BMI showed a trend toward higher values at ages 20-24 for early-onset CRC and 30-34 for other gastrointestinal cancers. In contrast, later-onset CRC and other gastrointestinal cancers exhibited higher BMI values at later ages (30-34 and 35-39, respectively). Early-onset uterine cancer was linked to a higher BMI compared to later-onset cancer (34.0 vs. 31.1 kg/m2, p < 0.0001), with a trend towards a higher BMI before 19 years old.

CONCLUSIONS

Our nationally representative data reveal that higher and earlier body fatness in adulthood associates with early-onset gastrointestinal and uterine cancers. These findings underscore the importance of intensifying efforts to combat early-life obesity.

Government Housing Assistance and Cancer Screening Among Adults With Low Income

INTRODUCTION

Access to affordable housing may support cancer control for adults with low income by alleviating financial barriers to preventive care. This study examines relationships between cancer screening and receipt of government housing assistance among adults with low income.

METHODS

Data are from the 2019 and 2021 National Health Interview Survey. Eligible respondents were classified as up-to-date or not with breast cancer (BC), cervical cancer (CVC) and colorectal cancer (CRC) screening guidelines. Multivariable logistic regression was used to model guideline-concordant screening by receipt of government housing assistance, overall and stratified by urban-rural status, race/ethnicity, and age. Analyses were performed in 2023.

RESULTS

Analyses for BC, CVC and CRC screening included 2,258, 3,132, and 3,233 respondents, respectively. There was no difference in CVC screening by housing assistance status, but screening for BC and CRC was higher among those who received assistance compared to those who did not (59.7% vs. 50.8%, p<0.01 for BC; 57.1% vs. 44.1%, p<0.01 for CRC). In models adjusted for sociodemographic characteristics, health status and insurance, these differences were not statistically significant for either BC or CRC screening. In stratified adjusted models, housing assistance was statistically significantly associated with increased BC screening in urban areas (aOR=1.35, 95% CI=1.00-1.82) and among Hispanic women (aOR=2.20, 95% CI=1.01-4.78) and women 45-54 years of age (aOR=2.10, 95% CI=1.17-3.75).

CONCLUSIONS

Policies that address housing affordability may enhance access to BC screening for some subgroups, including women in urban areas, Hispanic women, and younger women. More research on the mechanisms that link housing assistance to BC screening is needed.

Economic Evaluation of a Nonmedical Financial Assistance Program on Missed Treatment Appointments Among Adults With Cancer

PURPOSE

We retrospectively evaluated the clinical and economic impact of a program providing nonmedical financial assistance on missed treatment appointments among patients receiving cancer treatment at a large, Southeastern public hospital system.

MATERIALS AND METHODS

We used patient electronic health records, program records, and cancer registry data to examine the impact of the program on rates of missed (or no-show) radiation therapy and infusion chemotherapy/immunotherapy appointments in the 180 days after treatment initiation. We used propensity weighting to estimate the effect of the program, stratified by treatment appointment type (radiation therapy, infusion chemotherapy/immunotherapy). We developed a decision tree-based economic model to conduct a cost-consequence analysis from the health system perspective in a hypothetical cohort over a 6-month time horizon.

RESULTS

Of 1,347 patients receiving radiation therapy between 2015 and 2019, 53% (n = 715) had ≥1 no-shows and 28% (n = 378) received program assistance. Receipt of any assistance was associated with a 2.1 percentage point (95% CI, 0.6 to 3.5) decrease in the proportion of no-shows, corresponding to a 51% decrease in the overall mean no-show proportion. Under the current funding model, the program is estimated to save the health system $153 in US dollars per missed appointment averted, relative to not providing nonmedical financial assistance. Of the 1,641 patients receiving infusion chemotherapy/immunotherapy, 33% (n = 541) received program assistance, and only 14% (n = 223) had ≥1 no-shows. The financial assistance program did not have a significant effect on no-show proportions among infusion visits.

CONCLUSION

This study used a novel approach to retrospectively evaluate a nonmedical financial assistance program for patients undergoing active cancer treatment. Findings support investment in programs that address patients' nonmedical financial needs, particularly for those undergoing intensive radiation therapy.

The impact of racism on subsequent healthcare use and experiences for adult New Zealanders: a prospective cohort study

BACKGROUND

Racism is an important determinant of health and driver of racial/ethnic health inequities. Experience of racism has been linked to negative healthcare use and experiences although most studies have been cross-sectional. This study examines the relationship between reported experience of racism and subsequent use and experience of health services.

METHODS

This is a prospective cohort study design. The 2016/2017 adult New Zealand Health Survey (NZHS) provided the sampling frame and baseline data on exposures, health status and confounders. This stand-alone study invited all exposed individuals to participate when sampled based on their reported experience of racism (ever), stratified by broad ethnic groupings (Māori, Pacific, Asian, European/Other). Equal numbers of unexposed participants were selected for invitation using propensity score matching (propensity to experience racism, based on key available predictive factors). Follow-up was one to two years after NZHS interview. Outcome variables (last 12 months) were: unmet healthcare need (overall, for mental health, for a general practitioner); satisfaction with usual medical centre; and experiences with general practitioners (explaining care, involvement in decision-making, treated with respect/dignity, confidence and trust). Logistic regression models examining the association between experience of racism (at baseline) and health service use and experience (at follow-up) used doubly-robust estimation to weight for propensity scores used in the sampling with additional adjustment for confounders.

RESULTS

The study had 2010 participants. Experience of racism (ever) at baseline was associated with higher overall unmet need at follow-up (adjusted OR (aOR) = 1.71, 95% CI 1.31, 2.23), with similar patterns for other unmet need measures. Experience of racism was associated with higher dissatisfaction with a usual medical centre (aOR = 1.41, 95% CI 1.10, 1.81) and with higher reporting of negative patient experiences.

CONCLUSION

In line with how racism structures oppression, exposure to racism is largely felt by non-European groups in Aotearoa New Zealand. Experiences of racism potentially lead to poorer healthcare and healthcare inequities through higher unmet need, lower satisfaction and more negative experiences of healthcare. The health system has a critical role to play in addressing racism within healthcare and supporting societal efforts to eliminate racism and ethnic inequities.

Comparison of Health Care Utilization in Different Usual Sources of Care Among Older People With Cardiovascular Disease in China: Evidence From the Study on Global Ageing and Adult Health

Objectives: To compare the health care utilization in different usual sources of care (USCs) among the elderly population with cardiovascular disease in China. Methods: Cross-sectional data for 3,340 participants aged ≥50 years with cardiovascular disease from Global AGEing and Adult Health (2010)-China were used. Using the inverse probability of treatment weighting on the propensity score with survey weighting, combined with negative binomial regression and logistic regression models, the correlation between USCs and health care utilization was assessed. Results: Patients using primary care facilities as their USC had fewer hospital admissions (IRR = 0.507, 95% CI = 0.413, 0.623) but more unmet health needs (OR = 1.657, 95% CI = 1.108, 2.478) than those using public hospitals. Patients using public clinics as their USC had higher outpatient visits (IRR = 2.188, 95% CI = 1.630, 2.939) than the private clinics' group. Conclusion: The difference in inpatient care utilization and unmet health care needs between public hospitals and primary care facilities, and the difference in outpatient care utilization between public and private clinics were significant. Using primary care facilities as USCs, particularly public ones, appeared to increase care accessibility, but it still should be strengthened to better address patients' health care needs.

Identifying Causal Risk Factors for Self-Harm Among Adolescents With U.S. Child Protective Services Contact

OBJECTIVES

To estimate effects of potentially modifiable risk factors for self-harm among adolescents in the Child Protective Services (CPS) system.

METHODS

Data came from the National Survey of Child and Adolescent Well-being, a nationally representative longitudinal survey. Candidate risk factors included child's feelings of worthlessness, the presence of supportive adults in the child's life, and parental psychological aggression. Propensity score weighting (PSW) was used to control for observed confounders, and the average effect of experiencing the risk factor among those who did was estimated using weighted logistic regression.

RESULTS

Odds ratios for self-harm comparing youth with low and high parental psychological aggression to none were 0.93 (0.35-2.45) and 1.25 (0.55-2.82), respectively. The OR for feelings of worthlessness was 1.73 (0.70-4.27), and for supportive adults 0.58 (0.28-1.19). The combination of survey and propensity score weights may have affected statistical power.

CONCLUSIONS

Preventing self-harm in adolescents requires a multifaceted approach given the existing evidence base and lack of strong associations with individual risk factors. Fostering supportive relationships with adults merits future research given the observed, non-significant 42% reduction in odds of self-harm among CPS involved youth who had a supportive relationship with an adult, compared to those who did not.

STEM doctorate recipients with disabilities experienced early in life earn lower salaries and are underrepresented among higher academic positions

There is paucity of data examining disparities in salary and representation for disabled scientists, which is needed to advance inclusion and equity for people with disabilities in STEM. Using data from the 2019 Survey of Doctorate Recipients (United States, N = 1,148,817), we show that doctorate recipients working in Science, Technology, Engineering and Mathematics (STEM) with disabilities experienced early in life (at age <25 yr) earned US$10,580 less per year (95% CI: -$13,661, -$7,499) than non-disabled workers. In the subset of academic workers, doctorate recipients with early disabilities earned $14,360 less (95% CI: -$17,546, -$11,175) than those without disabilities. We observed an underrepresentation of academics with disabilities in higher faculty ranks (χ2: 647.2; P < 0.0001), among Deans/Presidents (χ2: 27.4; P = 0.0004) and among those with tenure (χ2: 525; P < 0.0001). These findings support a need to expand inclusion efforts, provide equal opportunities for career advancement and improve working conditions for people with disabilities in STEM.

Association between first-line antidepressant use and risk of dementia in older adults: a retrospective cohort study

BACKGROUND

Prior studies suggested that antidepressant use is associated with an increased risk of dementia compared to no use, which is subject to confounding by indication. We aimed to compare the dementia risk among older adults with depression receiving first-line antidepressants (i.e., SSRI/SNRI) versus psychotherapy, which is also considered the first-line therapy for depression.

METHODS

This retrospective cohort study was conducted using the US Medical Expenditure Panel Survey from 2010 to 2019. We included adults aged ≥ 50 years diagnosed with depression who initiated SSRI/SNRI or psychotherapy. We excluded patients with a dementia diagnosis before the first record of SSRI/SNRI use or psychotherapy. The exposure was the patient's receipt of SSRI/SNRI (identified from self-report questionnaires) or psychotherapy (identified from the Outpatient Visits or Office-Based Medical Provider Visits files). The outcome was a new diagnosis of dementia within 2 years (i.e., survey panel period) identified using ICD-9/ICD-10 codes from the Medical Conditions file. Using a multivariable logistic regression model, we reported adjusted odds ratios (aORs) with 95% confidence intervals (CIs). We also conducted subgroup analyses by patient sex, age group, race/ethnicity, severity of depression, combined use of other non-SSRI/SNRI antidepressants, and presence of underlying cognitive impairment.

RESULTS

Among 2,710 eligible patients (mean age = 61 ± 8, female = 69%, White = 84%), 89% used SSRIs/SNRIs, and 11% received psychotherapy. The SSRI/SNRI users had a higher crude incidence of dementia than the psychotherapy group (16.4% vs. 11.8%), with an aOR of 1.36 (95% CI = 1.06-1.74). Subgroup analyses yielded similar findings as the main analyses, except no significant association for patients who were aged < 65 years (1.23, 95% CI = 0.93-1.62), male (1.34, 95% CI = 0.95-1.90), Black (0.76, 95% CI = 0.48-1.19), had a higher PHQ-2 (1.39, 95% CI = 0.90-2.15), and had underlying cognitive impairment (1.06, 95% CI = 0.80-1.42).

CONCLUSIONS

Our findings suggested that older adults with depression receiving SSRIs/SNRIs were associated with an increased dementia risk compared to those receiving psychotherapy.

Disability and morbidity among US birth cohorts, 1998-2018: A multidimensional test of dynamic equilibrium theory

A substantial body of prior research has explored patterns of disability-free and morbidity-free life expectancy among older populations. However, these distinct facets of later-life health are almost always studied in isolation, even though they are very likely to be related. Using data from the US Health and Retirement Study and a multistate life table approach, this paper explores the interactions between disability, morbidity, and mortality by sex and education among four successive US birth cohorts, born from 1914 to 1923 to 1944-1953 and compared in the periods 1998-2008 and 2008-2018. We find little compression of disability but a marked expansion of morbidity across cohorts. However, disability-free life expectancy (DFLE) among those living with chronic morbidities has increased, even though at the population-level DFLE is largely unchanged. Broadly, these patterns suggest that successive cohorts of older populations in the US are experiencing a dynamic equilibrium, where the link between chronic morbidities and disability has weakened over successive cohorts. Investigating patterns by educational attainment, we find marked disparities where the least educated individuals not only live significantly fewer years free of disabilities or chronic morbidities but also have experienced an expansion in morbidity and disability. Our findings suggest that the future trajectory of disability-free life expectancy in the US is increasingly contingent on efforts to improve disease management and control the severe consequences of chronic morbidities.

Contemporary Trends in Clinical Characteristics, Therapeutic Strategies and Outcomes in Patients Aged 80 Years and Older Presenting with non-ST Elevation Myocardial Infarctions in the United States

The current guidelines for the management and treatment of acute coronary syndromes do not fully consider the role of age in guiding medical or invasive management. We investigated the characteristics, management strategies, and clinical outcomes of patients aged 80 years and older presenting with non-ST elevation myocardial infarction (NSTEMI). A cohort study using the nationwide inpatient sample database of patients aged 80 years and older presenting with NSTEMI in the United States between 2012 to 2018 was performed. About 24.2% (151,472/625,916) of NSTEMI patients were 80 years and older. Older patients (≥80 years) had higher in-hospital mortality and cardiovascular complications compared to younger patients (odds ratio (OR) 1.79, 95% confidence intervals (CI) 1.71-1.88, P < 0.001). Among older patients, conservative medical management was associated with higher inpatient mortality compared to percutaneous coronary intervention (PCI) (OR 2.3, 95% CI 2.18-2.41, P < 0.001) or coronary artery bypass graft (CABG) (OR 1.9, 95% CI 1.76-2.09, P < 0.001). The highest mortality rate was observed in older patients who underwent both PCI and CABG, followed by those treated conservatively and those undergoing coronary angiography without revascularization. This study provides valuable insights into the clinical characteristics and outcomes of elderly patients presenting with NSTEMI in the United States. The results emphasize the importance of a tailored approach to the management of ACS in elderly patients and the need for improved revascularization strategies to reduce in-hospital mortality and adverse cardiovascular outcomes. Therefore, the clinician should tailor the management of older patients presenting with NSTEMI.

Comparative effectiveness between mosunetuzumab monotherapy clinical trial and real-world data in relapsed/refractory follicular lymphoma in third or subsequent lines of systemic therapy

A comparison of clinical outcomes in the third or subsequent line (3 L+) of systemic therapy between a real-world data (RWD) external control cohort and a mosunetuzumab single-arm clinical trial cohort is presented. Data for 3 L + patients with relapsed/refractory follicular lymphoma (FL) were obtained from the mosunetuzumab single-arm trial (n = 90) and a US electronic health records database (n = 158), with patients meeting key eligibility criteria from the trial, balanced on pre-specified prognostic factors. Overall response and complete response rates were 80% and 60% in the mosunetuzumab cohort and 75% and 33% in the RWD cohort, odds ratios of 1.23 (95% CI, 0.52-2.93) and 3.18 (95% CI, 1.41-7.17), respectively. Hazard ratios for progression-free survival and overall survival were 0.82 (95% CI, 0.53-1.27) and 0.43 (95% CI, 0.19-0.94). These findings support a clinically meaningful benefit of mosunetuzumab monotherapy as a chemotherapy-free option for the 3 L + FL population.

Federal Housing Assistance and Chronic Disease Among US Adults, 2005-2018

Introduction

Housing insecurity is associated with poor health outcomes. Characterization of chronic disease outcomes among adults with and without housing assistance would enable housing programs to better understand their population's health care needs.

Methods

We used National Health and Nutrition Examination Survey (NHANES) data from 2005 through 2018 linked to US Department of Housing and Urban Development (HUD) administrative records to estimate the prevalence of obesity, diabetes, and hypertension and to assess the independent associations between housing assistance and chronic conditions among adults receiving HUD assistance and HUD-assistance-eligible adults not receiving HUD assistance at the time of their NHANES examination. We estimated propensity scores to adjust for potential confounders among linkage-eligible adults who had an income-to-poverty ratio less than 2 and were not receiving HUD assistance. Sensitivity analysis used 2013-2018 NHANES cycles to account for disability status.

Results

Adults not receiving HUD assistance had a significantly lower adjusted prevalence of obesity (42.1%; 95% CI, 40.4%-43.8%) compared with adults receiving HUD assistance (47.5%; 95% CI, 44.8%-50.3%), but we found no differences for diabetes and hypertension. We found significant associations between housing assistance and obesity (adjusted odds ratio = 1.29; 95% CI, 1.12-1.47), but these were not significant in the sensitivity analysis with and without controlling for disability status. We found no significant associations between housing assistance and diabetes or hypertension.

Conclusion

Based on data from a cross-sectional survey, we observed a higher prevalence of obesity among adults with HUD assistance compared with HUD-assistance-eligible adults without HUD assistance. Results from this study can help inform research on understanding the prevalence of chronic disease among adults with HUD assistance.

Prevalence, Correlates, and Impact of Psychiatric Disorders and Treatment Utilization Among Muslims in the United States: Results from the National Epidemiological Survey of Alcohol and Related Conditions

There is a paucity of research on the true prevalence of psychiatric disorders in Muslim Americans. This research aims to explore the prevalence, correlates and impact of mood disorders, anxiety disorders, and posttraumatic stress disorders (PTSD) in Muslims as compared with a non-Muslim sample. We used propensity scores to match 372 individuals who self-identified as Muslims from The National Epidemiologic Survey on Alcohol and Related Conditions III with a control group (n = 744) from the same dataset. The prevalence of psychiatric disorders was similar in Muslim Americans and non-Muslims. Help-seeking was generally low, but Muslims with a lifetime history of PTSD were less likely than non-Muslims with PTSD to seek help through self-help groups (2.2% vs. 21.1%, p < 0.05). Moreover, Muslims with mood disorders experienced lower mental health scores compared to non-Muslims with mood disorders. Efforts need to be made to identify psychiatric disorders in this faith group and engage in treatment.

Maternal adverse childhood experiences on child growth and development in rural Pakistan: An observational cohort study

Maternal adverse childhood experiences (ACEs) have significant impacts on the next generation with links to negative birth outcomes, impaired cognitive development, and increased socioemotional problems in children. However, not all types or levels of adversity are similarly deleterious and research from diverse contexts is needed to better understand why and how intergenerational transmission of adversity occurs. We examined the role of maternal ACEs on children's growth, cognitive, and socioemotional development at 36 months postpartum in rural Pakistan. We used data from 877 mother-child dyads in the Bachpan Cohort, a birth cohort study. Maternal ACEs were captured using an adapted version of the ACE-International Questionnaire. Outcomes at 36 months of age included child growth using the WHO growth z-scores, fine motor and receptive language development assessed with the Bayley Scales of Infant and Toddler Development, and socioemotional and behavioral development measured with the Ages and Stages Questionnaire: Socioemotional and Strengths and Difficulties Questionnaire. To estimate the associations between maternal ACEs and child outcomes, we used multivariable generalized linear models with inverse probability weights to account for sampling and loss to follow-up. Over half of mothers in our sample (58%) experienced at least one ACE. Emotional abuse, physical abuse, and emotional neglect were the most commonly reported ACEs. We found null relationships between the number of maternal ACEs and child growth. Maternal ACEs were associated with higher fine motor and receptive language development and worse socioemotional and behavioral outcomes. Maternal ACE domains had similarly varying relationships with child outcomes. Our findings highlight the complexity of intergenerational associations between maternal ACEs and children's growth and development. Further work is necessary to examine these relationships across cultural contexts and identify moderating factors to mitigate potential negative intergenerational effects.

Similar Patient Satisfaction and Quality of Life Improvement Achieved with TKA and THA According to the Goodman Scale: A Comparative Study

Background: Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are effective treatments for severe knee and hip osteoarthritis. Historically, TKA has been associated with lower satisfaction than THA, but recent advances in knee surgery have led to lower dissatisfaction rates. This study aimed to compare the satisfaction and self-reported improvement in the quality of life of two cohorts of patients who underwent TKA and THA, respectively. Methods: This observational study compared two previously published cohorts of patients who underwent THA and TKA in a single university center. The Goodman scale was used to assess satisfaction and self-perception of improved quality of life after TKA and THA at a minimum one-year follow-up. Propensity score matching was used to balance age, gender, and follow-up between groups. Significance was set at 0.05. Results: The study included a total of 105 THAs and 131 TKAs. Both groups had high levels of satisfaction with pain relief, ability to do house/yard work, and overall satisfaction, with above 90% satisfaction rates. Regarding improvement in quality of life, both groups had 86% of patients reporting improvement as "much better." After propensity score matching, no significant difference was found between THA and TKA for any of the comparisons made using the Goodman scale. Conclusions: The study showed that both TKA and THA resulted in high levels of satisfaction and improvement in quality of life. There was no significant difference in satisfaction rates between TKA and THA, contrary to the historical trend of lower satisfaction rates for TKA.

The prevalence and treatment utilization of substance use disorders among Muslims in the United States: A national epidemiological survey

BACKGROUND AND OBJECTIVES

Research on substance use disorder (SUD) among Muslims in the United States (US) is limited. There are several unique factors, including denial and stigma, that make this population at risk of SUD. This study explored the prevalence, treatment utilization, and impact of SUD among Muslims in the US compared with a matched control group from general respondents.

METHODS

Data from 372 self-identified Muslims were obtained from the National Epidemiologic Survey on Alcohol and Related Conditions III. A matched non-Muslim control group (N = 744) were selected based on demographics and other SUD-related clinical variables. The impact of SUD was assessed using the 12-Item Short Form Health Survey (SF-12).

RESULTS

Among the 372 Muslims, 53 (10.85%) had lifetime alcohol/drug use disorder, while 75 (18.42%) had lifetime tobacco use disorder (TUD). With statistical significance, alcohol use disorder (AUD) was lower while TUD was higher in the Muslim group than in the control group. The rates of all other substances were not statistically different between the Muslim and control groups. The Muslim group have higher help-seeking and a lower mean score on the SF-12 emotional scale than the control group.

CONCLUSION AND SCIENTIFIC SIGNIFICANCE

Muslim Americans have higher prevalence of TUD, lower prevalence of AUD, and similar prevalence of other SUD compared to the public. Affected individuals have poor emotional functioning which may be exacerbated by the impact of stigma. This is the first study to estimate prevalence of variety of SUD in American Muslims from a national representative sample.

The Impact of Frailty on Outcomes Following Primary Total Hip Arthroplasty in Patients of Different Sex and Race: Is Frailty Equitably Detrimental?

BACKGROUND

Whether frailty impacts total hip arthroplasty (THA) patients of different races or sex equally is unknown. This study aimed to assess the influence of frailty on outcomes following primary THA in patients of differing race and sex.

METHODS

This is a retrospective cohort study utilizing a national database (2015-2019) to identify frail (≥2 points on the modified frailty index-5) patients undergoing primary THA. One-to-one matching for each frail cohort of interest (race: Black, Hispanic, Asian, versus White (non-Hispanic), respectively; and sex: men versus women) was performed to diminish confounding. The 30-day complications and resource utilizations were then compared between cohorts.

RESULTS

There was no difference in the occurrence of at least 1 complication (P > .05) among frail patients of differing race. However, frail Black patients had increased odds of postoperative transfusion (odds ratio [OR]: 1.34, 95% confidence interval [CI]: 1.02-1.77), deep vein thrombosis (OR: 2.61, 95% CI: 1.08-6.27), as well as >2-day hospitalization and nonhome discharge (P < .001). Frail women had higher odds of having at least 1 complication (OR: 1.67, 95% CI: 1.47-1.89), nonhome discharge, readmission, and reoperation (P < .05). Contrarily, frail men had higher 30-day cardiac arrest (0.2% versus 0.0%, P = .020) and mortality (0.3 versus 0.1%, P = .002).

CONCLUSION

Frailty appears to have an overall equitable influence on the occurrence of at least 1 complication in THA patients of different races, although different rates of some individual, specific complications were identified. For instance, frail Black patients experienced increased deep vein thrombosis and transfusion rates relative to their non-Hispanic White counterparts. Contrarily, frail women, relative to frail men, have lower 30-day mortality despite increased complication rates.

Is use of a smuggler to cross the US-Mexico border associated with mental health problems among undocumented immigrants from Mexico?

Although numerous studies have found that Latine immigrants to the United States (US) have better health outcomes on average than persons born in the US, studies of persons living in Mexico have found that undocumented immigrants have worse health, especially those that were deported, compared to Mexican citizens that never migrated or migrated with authorization. However, the health outcomes of Mexican migrants using a smuggler to cross the US-Mexico border is a gap in the literature. We hypothesized that undocumented immigrant adults who used a smuggler to cross the US-Mexico border would be more likely to report mental health problems upon return to Mexico compared with undocumented immigrant adults that did not use a smuggler. We analyzed nationally representative, cross-sectional survey data of 1,563 undocumented immigrants currently living in Mexico. Most undocumented immigrants in the sample (87%) used a smuggler. Use of a smuggler by undocumented immigrant adults was associated with a 4.7% higher prevalence of emotional or psychiatric problems compared to undocumented immigrant adults that did not use a smuggler. We conclude that modality of ingress into the US is a risk factor for poorer mental health among undocumented immigrant adults.

Protein-Energy Malnutrition Is Associated with Worse Outcomes in Patients with Atrial Fibrillation: A Nationwide Analysis

Protein-energy malnutrition (PEM), which leads to a reduced ability of tissues to regenerate and repair themselves, may exacerbate many chronic diseases, including atrial fibrillation (AF), which occurs as a response of the heart to chronic inflammation. However, population-based studies examining the association between PEM and the prevalence and health care burden of AF are lacking. The aim of this retrospective cohort study was to estimate the impact of PEM on the prevalence and clinical outcomes of hospitalization for AF. The National Inpatient Sample (NIS) 2016 and 2017 datasets were searched for data on hospitalized adult patients with AF as a principal diagnosis; we subsequently identified AF patients with and without PEM as a secondary diagnosis using International Classification of Diseases, Tenth Revision (ICD-10), codes. The primary outcome of our study was inpatient mortality, while the secondary outcomes were hospital length of stay (LOS), total hospital cost (THC), cardiogenic shock, pacemaker insertion, successful ablation, and restoration of cardiac rhythm. Propensity score-weighted analysis was used accordingly to adjust for confounders. Out of 821,630 AF hospitalizations, 21,385 (3%) had PEM. Hospitalization for AF with PEM led to a statistically significant increase in mortality (adjusted odds ratio [aOR], 2.30; 95% confidence interval [CI], 1.93-2.75; P < .001) with an adjusted increase in the THC of $15,113 (95% CI, 11,246-18,980; P < .001), a 2-day increase in the LOS (95% CI, 1.92-2.41; P < .001), increased odds of cardiogenic shock (aOR, 1.36; 95% CI, 1.01-1.85; P = .04), and decreased odds of undergoing successful ablation (aOR, .71; 95% CI,.56-.88; P = .002) and achieving the restoration of cardiac rhythm (aOR, 0.56; 95% CI, 0.49-0.0.63; P ≤ .001) compared to those without PEM. These results indicate that PEM is associated with worse in-hospital outcomes in patients with AF. This potential association suggests that nutritional rehabilitation may be essential for improving hospitalization outcomes in AF patients.

The impact of COVID-19 on hospitalization outcomes of patients with acute myocardial infarction in the USA

Background/study objective

The effect of the COVID-19 pandemic affected health care delivery, as it led to variable outcomes in different disease states including cardiovascular diseases. In this study, we evaluated the impact of coexisting COVID-19 on Acute Myocardial Infarction (AMI).

Design/setting

We analyzed discharge records of AMI patients from the National Inpatient Sample (NIS) in the year 2020.

Main outcome measures

Using propensity score matching, we assessed the impact of COVID-19 infection on the in-hospital outcomes of patients presenting with AMI.

Results

There were 1154 patients with concomitant COVID-19 infection and AMI who were matched with 109,990 patients with AMI and without COVID-19. We found that patients with COVID-19 who had AMI were less likely to have dyslipidemia (64.6 % vs. 70.4 %, p < 0.001), peripheral vascular disease (2.4 % vs. 3.8 % p = 0.0017), smoking history (23.5 % vs. 28.2 % p < 0.0001) and hypertension (37.1 % vs. 40.1 % p = 0.004).COVID-19 was associated with higher hospital mortality rates (Adjusted odds ratio aOR: 2.72, CI: 2.23-3.30, p < 0.001), cardiac arrest (aOR: 1.65, 95 % CI: 1.26-2.15, p < 0.001), cardiogenic shock (aOR:1.36,95 % CI: 1.10-1.68, p = 0.004) and respiratory failure (aOR:1.81, 95 % CI: 1.55-2.11 p < 0.001) compared to AMI patients without COVID-19. There was also a significant association between coexisting COVID-19 and longer duration of hospital stay (Adjusted mean differences:1.40, 95 % CI: 1.31-1.59 p < 0.0001) in AMI patients.

Conclusion

COVID-19 infection is associated with worse in-hospital mortality and cardiorespiratory complications in patients with AMI.

Method comparison and estimation of causal effects of insomnia on health outcomes in a survey sampled population

Applying causal inference methods, such as weighting and matching methods, to a survey sampled population requires properly incorporating the survey weights and design to obtain effect estimates that are representative of the target population and correct standard errors (SEs). With a simulation study, we compared various approaches for incorporating the survey weights and design into weighting and matching-based causal inference methods. When the models were correctly specified, most approaches performed well. However, when a variable was treated as an unmeasured confounder and the survey weights were constructed to depend on this variable, only the matching methods that used the survey weights in causal estimation and as a covariate in matching continued to perform well. If unmeasured confounders are potentially associated with the survey sample design, we recommend that investigators include the survey weights as a covariate in matching, in addition to incorporating them in causal effect estimation. Finally, we applied the various approaches to the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) and found that insomnia has a causal association with both mild cognitive impairment (MCI) and incident hypertension 6-7 years later in the US Hispanic/Latino population.

Is socioeconomic status related to youth e-cigarette use? Examining family affluence and sexual identity

There is limited evidence about the relationship between socioeconomic status (SES) and youth electronic cigarette use, particularly among sexual minorities. This study investigates whether family affluence is significantly associated with e-cigarette use among youth, including sexual minority youth. Data came from the 2021 National Youth Tobacco Survey (N = 10,515). The prevalence of e-cigarette use for all participants and sexual minority youth (N = 1376) by SES was calculated and ranked according to the Family Affluence Scale. A propensity score weighting method was used to address the imbalance in characteristics among SES groups. The associations of SES with current e-cigarette use and current flavored e-cigarette use were estimated using univariate survey logistic regression for all participants and self-identified sexual minority students. The prevalence of e-cigarette use was similar among socioeconomic groups for all participants and sexual minorities. The propensity score weighting analysis showed no significant association between SES and current e-cigarette use for all participants and sexual minority students. Equally, there was no significant association between SES and current flavored e-cigarette use. Findings suggest that other protective and risk factors might explain youth e-cigarette use more than SES (family affluence scale).

Determinants of life expectancy at birth: a longitudinal study on OECD countries

This paper analyses the influence of several determinants on life expectancy at birth in 36 OECD countries over the 1999-2018 period. We utilized a cross-country fixed-effects multiple regression analysis with year and country dummies and used dynamic models, backward stepwise selection, and Arellano-Bond estimators to treat potential endogeneity issues. The results show the influence of per capita health-care expenditure, incidence of out-of-pocket expenditure, physician density, hospital bed density, social spending, GDP level, participation ratio to labour, prevalence of chronic respiratory diseases, temperature, and total size of the population on life expectancy at birth. In line with previous studies, this analysis confirms the relevance of both health care expenditure and health care system (physicians and hospital beds in our analysis) in influencing a country's population life expectancy. It also outlines the importance of other factors related to population behaviour and social spending jointly considered on this outcome. Policy makers should carefully consider these mutual influences when allocating public funds, particularly after the COVID-19 pandemic period.

Anxiety, depression, and concentration in cancer survivors: National Health and Nutrition Examination Survey results

PURPOSE

We report on prevalence of anxiety, depression, and concentration difficulties and their associations in survivors of cancer in a nationally representative sample up to 25 years after diagnosis.

METHODS

Using the National Health and Nutrition Examination Survey (NHANES) data from 2015 to 2018, participants between the ages of 18 and 79 self-reported on cancer history, symptoms of anxiety, depression, and difficulties with concentration.

RESULTS

Of 10,337 participants, 691 (6.7%) reported a previous diagnosis of cancer; the median time since diagnosis was 8 years. Prevalence was similar between those with and without cancer for anxiety (45.8% versus 46.9%) and depression (19.7% versus 20.0%). Concentration difficulties were more common (11.3% versus 9.0%) for those with a history of cancer compared to those without (adjusted OR = 1.38, 95% CI: 1.00-1.90). Prevalence of mental health symptoms was not related to time since diagnosis. Anxiety and depression were highly correlated (r = 0.81, 95% CI: 0.74-0.86) and moderately correlated with difficulty with concentration (r = 0.52, 95%CI: 0.40-0.64 and r = 0.64, 95% CI: 0.53-0.74 respectively).

CONCLUSIONS

Difficulty with concentration was more commonly reported by participants with than without a cancer history. Report of anxiety and depression was no different between participants with and without a history of cancer. Anxiety, depression, and difficulties with concentration were strongly related. Further research is needed to explore if there is a causal association, and if so, the direction of these correlations, so that interventions may be appropriately targeted.

Association between metabolic syndrome components and gingival bleeding is women-specific: a nested cross-sectional study

BACKGROUND

Metabolic syndrome (MetS) is a cluster of atherosclerotic risk factors that increases cardiovascular risk. MetS has been associated with periodontitis, but the contribution of single MetS components and any possible sexual dimorphism in this relation remain undetermined.

METHODS

Using the third National Health and Nutrition Examination Survey (NHANES III), we performed a nested cross-sectional study to test whether individuals aged > 30 years undergoing periodontal evaluation (population) exposed to ≥ 1 MetS component (exposure) were at increased risk of bleeding/non-bleeding periodontal diseases (outcome) compared to nonexposed individuals, propensity score matched for sex, age, race/ethnicity, and income (controls). The association between MetS components combinations and periodontal diseases was explored overall and across subgroups by sex and smoking. Periodontal health status prediction based on MetS components was assessed.

RESULTS

In total, 2258 individuals (n. 1129/group) with nested clinical-demographic features were analyzed. Exposure was associated with gingival bleeding (+ 18% risk for every unitary increase in MetS components, and triple risk when all five were combined), but not with stable periodontitis; the association was specific for women, but not for men, irrespective of smoking. The only MetS feature with significant association in men was high BP with periodontitis. CRP levels significantly increased from health to disease only among exposed women. MetS components did not substantially improve the prediction of bleeding/non-bleeding periodontal disease.

CONCLUSION

The observed women-specific association of gingival bleeding with single and combined MetS components advances gender and precision periodontology. Further research is needed to validate and expand these findings.

Food security status and breast cancer screening among women in the United States: Evidence from the Health and Retirement Study and Health Care and Nutrition Study

PURPOSE

To assess the impact of food insecurity on biennial breast cancer screenings (i.e., mammography or breast X-ray) among older women in the United States (US).

METHODS

Data from the 2014 and 2016 waves of the Health and Retirement Study and the 2013 Health Care and Nutrition Study were used. The analyses were limited to a nationally representative sample of 2,861 women between 50 and 74 years of age, residing in the US. We employed a propensity score weighting method to balance observed confounders between food-secure and food-insecure women and fit a binary logistic regression to investigate population-level estimates for the association between food security and breast cancer screening.

RESULTS

Food insecurity was significantly associated with failure to obtain a mammogram or breast X-ray within the past two years. Food-insecure women had 54% lower odds of reporting breast cancer screening in the past 2 years (adjusted OR = 0.46; 95% CI 0.30-0.70, p-value < 0.001) as compared to food-secure women. Additional factors associated with a higher likelihood of receiving breast cancer screenings included greater educational attainment, higher household income, regular access to health care/advice, not smoking, and not being physically disabled or experiencing depressive symptoms.

CONCLUSION

Results demonstrate a socioeconomic gradient existing in regard to the utilization of regular breast cancer screenings among women. Those who tend to have lower education, lower income, and lack of reliable healthcare access are more likely to be food insecure. Thus, more likely to face the financial, logistical, or environmental barriers in obtaining screening services that accompany food insecurity.

Association of corticosteroid use and attention deficit/hyperactivity disorder in asthmatic children varies by age

OBJECTIVE

We aim to examine the impact of corticosteroids use on ADHD among children with asthma by administration routes.

METHODS

A population-based, cross-sectional analysis included pediatric patients ages 5-20 years old from the 2016 and 2019 Kids Inpatient Database (unweighted N = 111,702). ICD-10-CM codes were used to identify corticosteroids use, asthma, and ADHD cases. Survey logistic regression models with purposeful variable selection algorithms were built to examine the association between corticosteroids use, and ADHD by asthma severity and age. An inverse probability weighting (IPW) approach was used to help further control residual confounding.

RESULTS

Among children aged 5-11 years old, the odds of ADHD were significantly higher in children with moderate to severe asthma who used inhaled corticosteroids than nonusers (moderate asthma: adjusted odds ratios [aOR] 1.46, 95% confidence interval [CI] 1.14-2.44; severe asthma: aOR 1.61, 95% CI 1.18-2.21). Although oral corticosteroid use was not independently associated with ADHD in young children, combined use of inhaled and oral corticosteroid had almost 5 times higher odds of use among ADHD in children with severe asthma vs. nonusers (aOR 4.85, 95% CI 2.07 - 11.35). No associations were found between any corticosteroid use and ADHD among asthmatic children aged 12-20 years.

CONCLUSIONS

In this retrospective analysis, we found inhaled corticosteroids were positively associated with ADHD in younger children with moderate to severe asthma, but not in older children.

Did Access to Ambulatory Care Moderate the Associations Between Visit Mode and Ancillary Services Utilization Across the COVID-19 Pandemic Period?

BACKGROUND/OBJECTIVE

In recent years, 2 circumstances changed provider-patient interactions in primary care: the substitution of virtual (eg, video) for in-person visits and the COVID-19 pandemic. We studied whether access to care might affect patient fulfillment of ancillary services orders for ambulatory diagnosis and management of incident neck or back pain (NBP) and incident urinary tract infection (UTI) for virtual versus in-person visits.

METHODS

Data were extracted from the electronic health records of 3 Kaiser Permanente Regions to identify incident NBP and UTI visits from January 2016 through June 2021. Visit modes were classified as virtual (Internet-mediated synchronous chats, telephone visits, or video visits) or in-person. Periods were classified as prepandemic [before the beginning of the national emergency (April 2020)] or recovery (after June 2020). Percentages of patient fulfillment of ancillary services orders were measured for 5 service classes each for NBP and UTI. Differences in percentages of fulfillments were compared between modes within periods and between periods within the mode to assess the possible impact of 3 moderators: distance from residence to primary care clinic, high deductible health plan (HDHP) enrollment, and prior use of a mail-order pharmacy program.

RESULTS

For diagnostic radiology, laboratory, and pharmacy services, percentages of fulfilled orders were generally >70-80%. Given an incident NBP or UTI visit, longer distance to the clinic and higher cost-sharing due to HDHP enrollment did not significantly suppress patients' fulfillment of ancillary services orders. Prior use of mail-order prescriptions significantly promoted medication order fulfillments on virtual NBP visits compared with in-person NBP visits in the prepandemic period (5.9% vs. 2.0%, P=0.01) and in the recovery period (5.2% vs. 1.6%, P=0.02).

CONCLUSIONS

Distance to the clinic or HDHP enrollment had minimal impact on the fulfillment of diagnostic or prescribed medication services associated with incident NBP or UTI visits delivered virtually or in-person; however, prior use of mail-order pharmacy option promoted fulfillment of prescribed medication orders associated with NBP visits.
