Migration background and use of preventive healthcare services: Findings of the German Ageing Survey

BackgroundThis study aimed to investigate the relationship between migration background and the utilization of preventive healthcare services.MethodsCross-sectional data from wave 5 in the year 2014, with a sample size of 7,684 individuals, were extracted from the nationally representative German Ageing Survey. The survey included community-dwelling individuals aged 40 years and above, with migration background serving as the primary independent variable. The outcomes measured included participation in cancer screenings, flu vaccinations, and routine health check-ups. Multiple logistic regressions were used to examine the association between migration background and preventive healthcare services.ResultsRegressions showed that the presence of a migration background with personal migration experience (compared with not having a migration background) was associated with a lower likelihood of using preventive healthcare services. More precisely, compared to individuals not having a migration background, individuals with a migration background and personal migration experience had a lower likelihood of routine health check-ups (OR = 0.76, 95% CI: 0.61 to 0.95), flu vaccinations (OR = 0.75, 95% CI: 0.59 to 0.95) and cancer screenings (OR = 0.71, 95% CI: 0.57 to 0.89). In contrast, there was no significant association between the presence of a migration background without personal migration experience (compared with not having a migration background) and the use of preventive healthcare services.ConclusionIn conclusion, results showed differences between individuals without migration background and individuals with migration background (and with personal migration experience) in terms of using preventive healthcare services. It may be helpful to specifically address individuals with migration background (and with migration experience) in terms of using preventive healthcare services.

Preventive Healthcare Utilization among Asian Americans in the U.S.: Testing the Institute of Medicine’s Model of Access to Healthcare

The current research, guided by the intersectionality theory and the Institute of Medicine’s healthcare access model, explored the determinants of preventive care utilization within the Asian American community. Analyzing data from the Asian American Quality of Life Survey (with a sample size of 2535), logistic regression models were employed, incorporating various factors: demographic variables, immigration-related variables, health and access, and patient–provider relationship. Results revealed that longer stays in the U.S., having health insurance coverage, having a usual source of care, and higher satisfaction levels with prior healthcare services were associated with increased odds of utilizing preventive healthcare. These findings contribute to our comprehension of preventive care utilization among Asian Americans and offer practical insights for targeted interventions in social work and public health and strategic healthcare planning.

The effects of mobile primary health teams: Evidence from the Médico del Barrio strategy in Ecuador

Starting in 2017, Ecuador gradually expanded its primary healthcare access program nationwide using mobile traveling healthcare teams through the Estrategia Médico del Barrio (EMB) [or Neighborhood Doctor Strategy]. EMB teams, composed of a primary care physician, a nurse, and a community health worker, made home visits in marginalized areas. We estimate the impact of the EMB on health and utilization outcomes using nationally representative household surveys for 2006 (N = 55,666), 2012–13 (N = 92,500) and 2018–19 (N = 168,747). The treatment variable at the extensive margin is any exposure to EMB at the canton level. At the intensive margin, we use exposure in terms of weeks covered by EMB and the number and composition of EMB personnel per 1000 population. We identify outcomes of treated vs. non- or partially-treated cantons based on the random combination of the timing of the start of the program’s implementation and the timing of the survey interview, which varied across cantons. We use difference-in-difference (DD) and difference-in-difference-in-difference (DDD) frameworks, the latter for cantons with high indigenous concentration. We find significant effects on the reported health problem and preventive care, but mixed results in terms of curative healthcare. The DDD specification shows that EMB improved health problem diagnoses and preventive healthcare utilization, including in highly indigenous cantons, yet it seemed to have mixed results in terms of curative care use in Ecuador. Various alternative specifications and robustness tests do not qualitatively alter the main findings.

The design and implementation of a multi-center, pragmatic, individual-level randomized controlled trial to evaluate Baby2Home, an mHealth intervention to support new parents

BackgroundBecoming a parent is a transformative experience requiring multiple transitions, including the need to navigate several components of health care, manage any mental health issues, and develop and sustain an approach to infant feeding. Baby2Home (B2H) is a digital intervention built on the collaborative care model (CCM) designed to support families during these transitions to parenthood. ObjectivesWe aim to investigate the effects of B2H on preventive healthcare utilization for the family unit and patient-reported outcomes (PROs) trajectories with a focus on mental health. We also aim to evaluate heterogeneity in treatment effects across social determinants of health including self-reported race and ethnicity and household income. We hypothesize that B2H will lead to optimized healthcare utilization, improved PROs trajectories, and reduced racial, ethnic, and income-based disparities in these outcomes as compared to usual care. MethodsB2H is a multi-center, pragmatic, individual-level randomized controlled trial. We will enroll 640 families who will be randomized to: [1] B2H + usual care, or [2] usual care alone. Preventive healthcare utilization is self-reported and confirmed from medical records and includes attendance at the postpartum visit, contraception use, depression screening, vaccine uptake, well-baby visit attendance, and breastfeeding at 6 months. PROs trajectories will be analyzed after collection at 1 month, 2 months, 4 months, 6 months and 12 months. PROs include assessments of stress, depression, anxiety, self-efficacy and relationship health. ImplicationsIf B2H proves effective, it would provide a scalable digital intervention to improve care for families throughout the transition to new parenthood.

Pre-Pandemic and Recent Oral and Medical Health Care Utilization among Young American Indian Children and Their Caregivers

Children from diverse ethnic groups are at significantly increased risk for dental caries. In particular, American Indian (AI) children have the highest incidence of detal caries of any ethnic group. The COVID-19 pandemic dramatically restricted health care access, including preventive oral health care. Given this context, it is unclear whether or not preventive oral health care for AI children has resumed since lockdown. To address this question, we surveyed adult AI caregivers (N = 152) of children aged 0–5 years, assessing recent (12-month) and pre-COVID (for caregivers of children aged 3–5 years) preventive oral and medical health services. We also examined medical health care access and utilization among caregivers. Among children aged 3–5 years old, both pre-pandemic and past year medical care utilization were generally high (80 and 90%, respectively) as was any oral health care utilization (64 & 78%, respectively). Oral health check-ups were more common over the last year (62%) compared to pre-COVID (44%). Recent health care utilization among children 1–5 years old in this sample were generally comparable to national estimates, except for higher reported preventive medical care (99% vs. 87.6%, respectively) and higher preventive oral care (96% vs. 59.6%, respectively). More caregivers reported delaying or foregoing needed health care due to COVID (28–38%) versus due to cost (8–17%). In this survey of AI caregivers, recent child preventive health care utilization was high, and changes in utilization following the lockdown phases of the pandemic were comparable for oral and medical health care.

Identifying future high healthcare utilization in patients with multimorbidity – development and internal validation of machine learning prediction models using electronic health record data

PurposeTo develop and internally validate prediction models with machine learning for future potentially preventable healthcare utilization in patients with multiple long term conditions (MLTC). This study is the first step in investigating whether prediction models can help identify patients with MLTC that are most in need of integrated care.MethodsA retrospective cohort study was performed with electronic health record data from adults with MLTC from an academic medical center in the Netherlands. Based on demographic and healthcare utilization characteristics in 2017, we predicted ≥ 12 outpatient visits, ≥ 1 emergency department (ED) visits, and ≥ 1 acute hospitalizations in 2018. Four machine learning models (elastic net regression, extreme gradient boosting (XGB), logistic regression, and random forest) were developed, optimized, and evaluated in a hold-out dataset for each outcome.ResultsA total of 14,486 patients with MLTC were included. Based on the area under the curve (AUC) and calibration curves, the XGB model was selected as final model for all three outcomes. The AUC was 0.82 for ≥ 12 outpatient visits, 0.76 for ≥ 1 ED visits and 0.73 for ≥ 1 acute hospitalizations. Despite adequate AUC and calibration, precision-recall curves showed suboptimal performance.ConclusionsThe final selected models per outcome can identify patients with future potentially preventable high healthcare utilization. However, identifying high-risk patients with MLTC and substantiating if they are most in need of integrated care remains challenging. Further research is warranted investigating whether patients with high healthcare utilization are indeed the most in need of integrated care and whether quantitively identified patients match the identification based on clinicians’ experience and judgment.

Comparing situational influences on differential healthcare utilization trajectories in patients on home palliative care: A qualitative study.

Patients with terminal cancer receiving home palliative care present differential healthcare utilization trajectories before death. It remains unclear which situational elements influence these trajectories among disparate patient groups. The aim of this study was to compare situational influences on "persistently high" and "low stable" trajectories of healthcare utilization in patients who received palliative care support at home. Bereaved family caregivers were recruited from our prior quantitative study investigating healthcare utilization trajectories in oncology patients on home-based palliative care. In-depth interviews were conducted with 30 family caregivers. Data were analyzed using thematic analysis. Analysis of data uncovered how the 2 utilization trajectories were influenced by the interplay of 1 or more of 4 situational elements. Perceived symptom control in patients, influenced by their determination to die at home, shapes the susceptibility to situational contingencies, resulting in differential utilization trajectories. Caregivers' mental readiness in dealing with unexpected circumstances has a significant impact on the overall manageability of care, ultimately affecting decisions related to healthcare utilization. The concordance between symptom needs and scope of homecare services in a given situation proves to be an important determinant. Lastly, perceived accessibility to informal support in times of need acts as a contextual reinforcement, either preventing or precipitating decisions regarding healthcare utilizations. Our findings hold important implications for the provision of homecare services, in particular, the need for comprehensive assessment of end-of-life wishes during homecare enrolment and strengthening psychological preparedness of caregivers. Expansion of home-based clinical interventions tailored to high utilizers, and funding for temporary in-home respite should be considered to optimally manage potentially preventable acute healthcare utilization.

Exploring Preventive Health Care Utilization Among Black/African American Men.

Black/African American (BAA) men have the lowest life expectancy among other major demographic groups in the United States, with BAA male mortality rates 40% higher than their White male counterparts. Despite known benefits of preventive health care utilization, BAA men are 43% more likely to use the emergency department for usual care. Many intersecting factors like medical mistrust and religion have been identified as common barriers BAA men face in health care utilization with few studies exploring factors that impact their current preventive health care utilization. In addition, BAA men's perceptions of health and ability to identify or seek help have always been disproportionately lower than other racial groups despite higher rates of preventable diseases. Using the tenets of the Andersen Healthcare Utilization Model, this cross-sectional study of 176 BAA men explores BAA men's current preventive health care practices while examining the intersection of predisposing, enabling, and need factors on BAA men's preventive health care utilization. While it is well known that higher income levels and higher education positively influence health care utilization, the intersection of religious affiliation and higher levels of medical mistrust was associated with BAA men's decreased engagement with health care as religion posed as a buffer to health care utilization. This study demonstrated that BAA men's perception of health differed by sexual orientation, educational status, and income. However, across all groups the participants' perspective of their health was not in alignment with their current health outcomes. Future studies should evaluate the impact of masculine norms as potential enabling factors on BAA men's preventive health care utilization.

Critical Elements of Care Coordination for Older Persons in Rural Communities: An Evaluation of the Iowa Return to Community Service Demonstration.

We evaluated the Iowa Return to Community, a service demonstration designed to coordinate care and reduce preventable healthcare utilization among at-risk older persons living at home in rural communities. During 2021, 262 older persons elected to participate in the IRTC program. Individuals who participated were more likely to live in micropolitan areas (OR = 2.30, 95% CI 1.34-3.95) relative to metropolitan locations. Individuals who used recommended services were more likely to be men (OR 3.65, 95% CI 1.16-11.51) and more likely to live in rural (OR 17.48, 95% CI 1.37-223.68) and micropolitan areas (OR 3.17, 95% CI 1.00-10.05). However, prevention of health care use corresponded more with consistent and prolonged IRTC program engagement rather than volume of service use. The IRTC constitutes a population aging and rural health strategy to reduce unnecessary health care use while supporting individual preferences to remain at home.

Jail-based medication for opioid use disorder and patterns of reincarceration and acute care use after release: A sequence analysis

BackgroundTreatment with methadone and buprenorphine medications for opioid use disorder (MOUD) during incarceration may lead to better community re-entry, but evidence on these relationships have been mixed. We aimed to identify community re-entry patterns and examine the association between in-jail MOUD and a pattern of successful reentry defined by rare occurrence of reincarceration and preventable healthcare utilization. MethodsData came from a retrospective, observational cohort study of 6066 adults with opioid use disorder who were incarcerated in New York City jails and released to the community during 2011–14. An outcome was community re-entry patterns identified by sequence analysis of 3-year post-release reincarceration, emergency department visits, and hospitalizations. An exposure was receipt of in-jail MOUD versus out-of-treatment (42 % vs. 58 %) for the last 3 days before discharge. The study accounted for differences in baseline demographic, clinical, behavioral, housing, and criminal legal characteristics between in-jail MOUD and out-of-treatment groups via propensity score matching. ResultsThis study identified five re-entry patterns: stability (64 %), hospitalization (23 %), delayed reincarceration (7 %), immediate reincarceration (4 %), and continuous incarceration (2 %). After addressing confounding, 64 % and 57 % followed the stability pattern among MOUD and out-of-treatment groups who were released from jail in 2011, respectively. In 2012–14, the prevalence of following the stability pattern increased year-by-year while a consistently higher prevalence was observed among those with in-jail MOUD. ConclusionsSequence analysis helped define post-release stability based on health and criminal legal system involvement. Receipt of in-jail MOUD was associated with a marker of successful community re-entry.

Health care utilization by long-term survivors of blood or marrow transplantation-A Bone Marrow Transplant Survivor Study report.

Blood or marrow transplantation (BMT) survivors carry a high burden of morbidity, yet health care utilization by this vulnerable population remains understudied. Patterns and predictors of various domains of health care utilization in long-term BMT survivors were evaluated. Study participants were drawn from the Bone Marrow Transplant Survivor Study (BMTSS). Patients transplanted between 1974 and 2014 at one of three transplant centers who had survived ≥2years after BMT and were aged ≥18 years at the time of the study were included. A BMTSS survey served as the source of data for health care utilization, sociodemographics, and chronic health conditions. Domains of health care utilization in the 2 years preceding study participation included routine checkups, BMT-related visits, transplant/cancer center visits, emergency room (ER) visits, hospitalizations, and high health care utilization (≥7 physician visits during the 2 years before the study). Clinical characteristics and therapeutic exposures were abstracted from medical records. In this cohort of 3342 BMT survivors (52% allogeneic), the prevalence of health care utilization declined over time since BMT for both allogeneic and autologous BMT survivors, such that among those who had survived ≥20 years, only 49%-53% had undergone routine checkups, 37%-38% reported BMT-related visits, and 28%-29% reported transplant/cancer center visits. The presence of severe/life-threatening conditions and chronic graft-vs-host disease increased the odds of health care utilization across all domains. Lower education, lack of insurance, and Hispanic ethnicity were associated with a lower prevalence of routine checkups and/or transplant/cancer center visits. Lower income increased the odds of ER visits but reduced the odds of hospitalizations or high health care utilization. This study identified vulnerable populations of long-term BMT survivors who would benefit from specialized risk-based anticipatory care to reduce high health care utilization, ER visits, and hospitalizations.

Risk stratification tools in primary care in Europe

Abstract Risk stratification is an intentional, planned and proactive process that predicts the probability of adverse events occurring and assigns an individual a risk status or score. Based on individual risk assessment, patients are typically classified into high-, medium- (rising-) and low-risk groups. Risk levels should correspond to the likelihood that patients experience negative health outcomes and/or higher rates of unnecessary or preventable health care utilization. This allows targeting effective interventions to prevent them and promotes resource utilization based on individual and population needs rather than demand. Risk stratification is essential for PHC practices to be proactive and reach out to individuals based on their risk profile even if they do not present to PHC facilities and to tailor PHC service delivery accordingly. Even if risk stratification (especially as it becomes more sophisticated) is not done at the PHC level, the results can be made available to PHC professionals, often through integrated electronic health record systems, so they can benefit from it in their daily practice. Risk stratification may be carried out in PHC settings with varying degrees of complexity depending on local resources and with different purposes depending on the context. This presentation will discuss the different risk stratification tools used in country across the European region, and provide practical examples on their uses in PHC. The presentation will discuss enabling factors for advanced risk stratification that accounts for multimorbidity and social complexity.

One-Step Weighting to Generalize and Transport Treatment Effect Estimates to a Target Population

The problems of generalization and transportation of treatment effect estimates from a study sample to a target population are central to empirical research and statistical methodology. In both randomized experiments and observational studies, weighting methods are often used with this objective. Traditional methods construct the weights by separately modeling the treatment assignment and study selection probabilities and then multiplying functions (e.g., inverses) of their estimates. In this work, we provide a justification and an implementation for weighting in a single step. We show a formal connection between this one-step method and inverse probability and inverse odds weighting. We demonstrate that the resulting estimator for the target average treatment effect is consistent, asymptotically Normal, multiply robust, and semiparametrically efficient. We evaluate the performance of the one-step estimator in a simulation study. We illustrate its use in a case study on the effects of physician racial diversity on preventive healthcare utilization among Black men in California. We provide R code implementing the methodology.

Adverse Childhood Experiences and Family-Centered Care.

Adverse Childhood Experiences (ACEs) include experiences of child maltreatment and household dysfunction. Prior work has shown that children with ACEs may have suboptimal utilization of preventive health care, including annual well-visits, however little is known about the relationship between ACEs and quality of patient care. Using data from the 2020 National Survey of Children's Health (N = 22,760) a series of logistic regression models estimated associations between ACEs, both individually and cumulatively, and five components of family-centered care. Most ACEs were consistently associated with lower odds of family-centered care (e.g. financial hardship was associated with doctors always spend enough time with children, AOR = 0.53; 95% CI = 0.47, 0.61), except for having a parent or guardian die, which was associated with higher odds. Cumulative ACE score was also associated with lower odds of family-centered care (e.g. doctors always listened carefully to the parent, AOR = 0.86; 95% CI = 0.81, 0.90). These findings emphasize the importance of the consideration of ACEs in the context of family-centered care, and support the need for ACEs screening in the clinical setting. Future work should focus on mechanisms explaining the observed associations.

Delayed Diagnostic Paracentesis Is Associated with Increased Preventable Healthcare Utilization in Disadvantaged Patient Populations with Advanced Liver Disease and Elevated INR.

Patients hospitalized with cirrhosis, ascites, and elevated INR often experience delays in timely diagnostic paracentesis. Identify whether delays in diagnostic paracentesis were associated with adverse outcomes in a hospital system serving a large disadvantaged population. Retrospective cohort analysis of patients admitted from January 2017 to October 2019 with cirrhosis, ascites, and INR ≥ 1.5 across a multi-hospital health system in central Texas. We examined demographic and clinical characteristics of patients with diagnostic paracentesis (1) ≤ 24h; (2) > 24h; (3) therapeutic only or no paracentesis. We used logistic regression to examine differences in clinical outcomes controlling for confounders. 479 patients met inclusion criteria. 30.0% (N = 143) were Latino, 6.7% (N = 32) African American, and 67.8% (N = 325) under or uninsured. 54.1% of patients received a diagnostic paracentesis ≤ 24h of admission and 21.1% did not receive a diagnostic paracentesis during the hospitalization. Undergoing diagnostic paracentesis > 24h of admission was associated with a 2.3day increase in length of stay (95% CI 0.8-3.8), and OR 1.7 for an Emergency Room visit within 30days of discharge (95% CI 1.1-2.7) compared to receiving a diagnostic paracentesis ≤ 24h. Patients receiving diagnostic paracentesis in radiology were more likely to have a delay in procedure OR 5.8 (95% CI 2.8-8.6). Delayed diagnostic paracentesis is associated with increased preventable healthcare utilization compared with timely diagnostic paracentesis. Health systems should support efforts to ensure timely diagnostic paracentesis for patients with advanced liver disease, including performance at the bedside.

Health literacy and uptake of annual physical checkups among emerging adults in the United States: Findings from the Behavioral Risk Factor Surveillance System

AbstractPublic health literature is replete with evidence on the determinants of preventive healthcare utilization. However, gap exists in the relationship between health literacy, a key social determinant of health, and annual physical checkups, especially among younger adults in the United States. This age group is one of the least likely to utilize such services for screening and prevention of diseases, which can have a significant impact on their long‐term health as they progress through the life course. Using the Andersen Healthcare Utilization framework, this study investigated the association between health literacy, an enabling factor, and uptake of annual physical checkups among emerging adults aged 18–29. A binary logistic regression model was employed to achieve the study objective using data from the 2016 Behavioral Risk Factor Surveillance System data (N = 9515). Findings showed that 61% of young adults had physical checkups in the past year. After adjusting for predisposing, need, and other enabling factors, experiencing difficulties with oral and written health literacy and having difficulties obtaining medical information and advice were significantly associated with lower odds of physical checkups in the past year. These findings provide evidence for strategies like Healthy People 2030 that aim to increase preventive healthcare service utilization among emerging adults.

A Pharmacy Liaison–Patient Navigation Intervention to Reduce Inpatient and Emergency Department Utilization Among Primary Care Patients in a Medicaid Accountable Care Organization

Patients with unmet health-related social needs are at high risk for preventable health care utilization. Prior interventions to identify health-related social needs and provide navigation services with community resources have not taken place in pharmacy settings. To evaluate an enhancement of pharmacy care to reduce hospital admissions and emergency department (ED) visits among primary care patients in a Medicaid accountable care organization (ACO). This nonrandomized controlled trial was conducted from May 1, 2019, through March 4, 2021, with 1 year of follow-up. Study allocation was determined by odd or even medical record number. The study was performed at a general internal medicine practice at a large safety-net hospital in Boston, Massachusetts. Patients who qualified for the hospital's pharmacy care program (aged 18-64 years and within the third to tenth percentile for health care utilization and cost among Medicaid ACO membership) who attended a visit with a primary care clinician were eligible. Of 770 eligible patients, 577 were approached, 127 declined, and 86 could not be contacted. Patients in the control group received usual pharmacy care focused on medication adherence. Patients in the intervention group received enhanced pharmacy care with an additional focus on identification of and intervention for health-related social needs. The intervention took place for 1 year. The primary outcome was inpatient hospital admissions and ED visits (composite outcome) in the 12 months after enrollment during the intervention period. Among 364 allocated patients (mean [SD] age, 50.1 [10.1] years; 216 women [59.3%]), 35 were Hispanic of any race (9.6%) and 214 were non-Hispanic Black (58.8%). All participants were included in the intention-to-treat analysis. In analyses controlling for baseline hospital admissions and ED visits the year prior to enrollment, the enhanced pharmacy care group was not associated with the odds of having any hospital admission or ED visit (adjusted odds ratio, 0.62 [95% CI, 0.23-1.62]; P = .32) among all patients and was not associated with the visit rates among those with any visit (adjusted rate ratio, 0.93 [95% CI, 0.71-1.22]; P = .62) relative to the usual pharmacy care group in the year following enrollment. The findings of this nonrandomized controlled trial suggest that inpatient and ED utilization among Medicaid ACO members at a safety-net hospital was not significantly different between groups at 1-year follow-up. ClinicalTrials.gov Identifier: NCT03919084.

Trajectories of Preventive Health Care Utilization Among Older Koreans: The Role of Social Relationships.

Receiving timely health screening is associated with important public health benefits among older adults. By focusing on the role of social relationships, the present study was aimed at examining longitudinal trajectories of health screening use among older adults in Korea, whose universal health care system provides free-of-charge health screening. A nationally representative sample of 3,575 individuals aged 65 or older from wave one of the Korean Longitudinal Study of Aging (2006) was followed for 10 years (up to Wave 6, 2016). Mixed-effect logit models were used to investigate how an older adult's social relationship characteristics (i.e., household composition, financial support from family, social group participation, and the frequency of contact with friends or relatives) were associated with their trajectories of participation in the national health screening program. Despite the low financial burden, only 49.7% of older adults in Korea reported receiving the recommended health screening at the baseline. Although the probability of receiving recommended health screening increased over the 10-year study period, the trajectories were significantly different by an older adult's social relationship characteristics. All four social relationship characteristics were significantly associated with receiving health screening. However, those with more frequent social contacts and those who participated in social groups showed steeper increases in the probability of receiving health screening (i.e., significant interaction with time). This study highlights the importance of social relationships and intervention approaches that accommodate socially isolated older adults to facilitate their timely receipt of recommended preventive care.

Effects of marriage equality legislation on sexual health of the US population.

Even though prior research has investigated the relationship between same-sex partnership recognition policies and health outcomes, the impact of same-sex marriage laws on sexually transmitted infections has not received much attention. Using state-level panel data from 2000 to 2019, I show that marriage equality legislation decreases the spread of (shorter-term) syphilis infections and of (longer-term) human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) infections among the general population. Event study analyses correcting for non-staggered treatment implementation confirm these negative effects, but also suggest that standard difference-in-differences models understate the impact of the legislation by up to 8% points. Further analysis supports that these legislation effects operate through three mechanisms: increasing social tolerance, strengthening relationship commitment, and expanding health care access and coverage for HIV/AIDS prevention and treatment. Disaggregating the results by sexual behavior reveals that legal access to same-sex marriage leads to sizable decreases in AIDS rates among men who have sex with men (MSM) (the most at-risk population for an infection). Even though there is economically significant evidence that the legislation improves sexual health of the heterosexual population due to increased utilization of preventive sexual health care, the legislation does not have a direct impact on infection rates for the non-MSM population.

Assessing Risks of Early Childhood Caries in Primary Care Practice Using Electronic Health Records and Neighborhood Data.

Early childhood caries (ECC) is a persistent public health challenge, affecting more than 56% of US toddlers and preschool-aged children. Despite this, ECC is largely preventable with routine oral hygiene practices, diet, and application of topical fluoride. This study assessed the utilization of preventive oral health care in primary care practices and evaluated the variation in patient characteristic and geographic disparities. We conducted a retrospective study using electronic health records (EHRs) over a 2-year period. Patients' home addresses were geocoded and linked to census-based neighborhood statistics and fluoridated water accessibility. Multiple logistic regression modeling was used to assess the risk of ECC in patients with fluoride preventive care, controlled for demographics, comorbid conditions, and neighborhood risk factors. Patients aged 6 to 71 months who had primary care providers at family medicine and general pediatric clinics in a large academic medical center. The presence of dental caries based on diagnoses in EHRs. The study consisted of 10 836 patients: 17% treated with topical fluoride varnish (TFV), 12% prescribed oral fluoride supplement, 6.1% with both TFV and supplement, and 64% without fluoride treatment. Patients with fluoride treatment were 24% to 53% less likely to have ECC. Children living in rural and nonfluoridated water communities had 1.7 to 1.8 times greater risk of developing ECC. Minority, under/uninsured, and low-income patients also were at an increased risk of ECC. Despite continuing efforts to improve access to dental care for vulnerable populations, substantial disparities remain among socioeconomically disadvantaged children. To address dental care shortage, primary care clinicians should serve as the safety net to care for vulnerable and underserved children who have no or limited access to oral health services. Future research into the collaboration between primary care and dental providers at the level of both practice and professional education should be considered.
