A usual source of care: supplement or substitute for health insurance among low-income children?

Age of autism diagnosis in Latin American and Caribbean countries

LAY ABSTRACT

An earlier diagnosis of autism spectrum disorder might lead to earlier intervention. However, people living in Latin American and Caribbean countries do not have much knowledge about autism spectrum disorder symptoms. It has been suggested that the older a child is when diagnosed, the fewer opportunities he or she will have to receive services. We asked 2520 caregivers of autistic children in six different Latin America and Caribbean Countries, the child's age when they noticed some developmental delays and their child's age when they received their first autism spectrum disorder diagnosis. Results indicate that, on average, caregivers were concerned about their child's development by 22 months of age; however, the diagnosis was received when the child was 46 months of age. In addition, older children with better language abilities and public health coverage (opposed to private health coverage) were diagnosed later. On the contrary, children with other medical problems and more severe behaviors received an earlier diagnosis. In our study, children were diagnosed around the time they entered formal schooling, delaying the access to early intervention programs. In summary, the characteristics of the autistic person and the type of health coverage influence the age of diagnosis in children living in Latin America and Caribbean Countries.

Access to health services among sexual minority people in the United States

Sexual minority people in the United States are less likely to have access to health services when compared to their heterosexual counterparts. Less is known about the within-group sociodemographic memberships among sexual minority people regarding access to health services. Using data from a nationally representative sample, a series of univariate and bivariate analyses were used to determine associations between sociodemographic group membership and access to health services. Results suggest there are significant differences in access to health services within the sexual minority population. Differences in access to health services when considering sex-at-birth, sexual identity, age, race/ethnicity, urbanicity, education level and income status were found. These findings offer insight into the role sociodemographic group membership has on the equity of access to health services. Specifically, results indicated that disproportionate access to health services among sexual minority people were more pronounced among those with group membership who experience social marginalisation. This was particularly true for sexual minority people who were bisexual, younger, Black and Latinx, lower-income earners and sexual minority people with less education attainment. Results from this study may be used to inform policies and practices aimed at improving access to health services including, but not limited to, the expansion of the Affordable Care Act and continued development of Federally Qualified Health Centers, while acknowledging the role of within-group differences among sexual minority people.

Emergency Department/ Urgent Care as Usual Source of Care and Clinical Outcomes in CKD: Findings From the CRIC (Chronic Renal Insufficiency Cohort) Study

Rationale & Objective

Having a usual source of care increases use of preventive services and is associated with improved survival in the general population. We evaluated this association in adults with chronic kidney disease (CKD).

Study Design

Prospective, observational cohort study.

Setting & Participants

Adults with CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC) Study.

Predictor

Usual source of care was self-reported as: 1) clinic, 2) emergency department (ED)/urgent care, 3) other.

Outcomes

Primary outcomes included incident end-stage kidney disease (ESKD), atherosclerotic events (myocardial infarction, stroke, or peripheral artery disease), incident heart failure, hospitalization events, and all-cause death.

Analytical Approach

Multivariable regression analyses to evaluate the association between usual source of care (ED/urgent care vs clinic) and primary outcomes.

Results

Among 3,140 participants, mean age was 65 years, 44% female, 45% non-Hispanic White, 43% non-Hispanic Black, and 9% Hispanic, mean estimated glomerular filtration rate 50 mL/min/1.73 m². Approximately 90% identified clinic as usual source of care, 9% ED/urgent care, and 1% other. ED/urgent care reflected a more vulnerable population given lower baseline socioeconomic status, higher comorbid condition burden, and poorer blood pressure and glycemic control. Over a median follow-up time of 3.6 years, there were 181 incident end-stage kidney disease events, 264 atherosclerotic events, 263 incident heart failure events, 288 deaths, and 7,957 hospitalizations. Compared to clinic as usual source of care, ED/urgent care was associated with higher risk for all-cause death (HR, 1.53; 95% CI, 1.05-2.23) and hospitalizations (RR, 1.41; 95% CI, 1.32-1.51).

Limitations

Cannot be generalized to all patients with CKD. Causal relationships cannot be established.

Conclusions

In this large, diverse cohort of adults with moderate-to-severe CKD, those identifying ED/urgent care as usual source of care were at increased risk for death and hospitalizations. These findings highlight the need to develop strategies to improve health care access for this high-risk population.

Exploration of the psychometric properties of the Person-Centred Primary Care Measure (PCPCM) in a Chinese primary care population in Hong Kong: a cross-sectional validation study

OBJECTIVES

To evaluate the validity and psychometric properties of the Chinese Person-Centred Primary Care Measure (PCPCM) in a Chinese-speaking population.

DESIGN

A cross-sectional study.

SETTING

A primary care clinic in Hong Kong.

PARTICIPANTS

300 Chinese adult patients (150 males and 150 females) were recruited from a primary care clinic to complete a questionnaire containing the PCPCM, Consultation and Relational Empathy (CARE), Patient Enablement Index (PEI) and Adult (short version) Primary Care Assessment Tool (PCAT). The Chinese PCPCM was readministered to 118 participants after 14 days for test-retest reliability.

OUTCOME MEASURES

The construct validity, reliability and sensitivity of the Chinese PCPCM.

RESULTS

The Chinese PCPCM was identified to have a one-factor construct, with good item fit and unidimensionality on Rasch analysis. Internal reliability was high (Cronbach's alpha >0.8) with moderate test-retest reliability (intraclass correlation coefficient=0.622, p<0.001). Significant correlations (0.58, 0.42, 0.48) between the PCPCM and CARE, PEI and Adult (short version) PCAT scores supported good convergent construct validity. PCPCM scores were higher among patients who had known their doctors for a longer period or who were more likely to be able to see the same doctor at every visit, and among those who self-reported to have 'better health' rather than 'worse health'.

CONCLUSION

The Chinese PCPCM appears to be a valid, reliable and sensitive instrument for evaluating the quality of person-centred care among primary care patients in Hong Kong. Further studies are needed to confirm the utility of this instrument in other Chinese-speaking populations around the world.

The Impact of Restrictive Policies on Mexican Immigrant Parents and Their Children's Access to Health Care

Background: This study assessed whether policies that limit Mexican immigrants' access to care affects their children's access to a regular source of care, health insurance, and timely preventive health visits. Method: This was a cross-sectional study among Mexican immigrant parents who attended a health promotion program in Texas, Nevada, New York, and Illinois. A sociodemographic survey, including parental and child variables, was administered. Results: Children of parents without health insurance were almost four times more likely to be uninsured and eight times more likely to lack a regular source of care. Children of parents without a regular source of care were less than half as likely to have their own regular source of care than children whose parents had a regular source of care. Discussion: Findings suggest when parents are uninsured/lack a regular source of care, a child's health disparity is created. Reducing disparities in health care coverage, affecting foreign-born parents, positively impacts their children's access to care. Clinical Trial Registration number: NCT03209713.

A New Comprehensive Measure of High-Value Aspects of Primary Care

PURPOSE

To develop and evaluate a concise measure of primary care that is grounded in the experience of patients, clinicians, and health care payers.

METHODS

We asked crowd-sourced samples of 412 patients, 525 primary care clinicians, and 85 health care payers to describe what provides value in primary care, then asked 70 primary care and health services experts in a 2½ day international conference to provide additional insights. A multidisciplinary team conducted a qualitative analysis of the combined data to develop a parsimonious set of patient-reported items. We evaluated items using factor analysis, Rasch modeling, and association analyses among 2 online samples and 4 clinical samples from diverse patient populations.

RESULTS

The resulting person-centered primary care measure parsimoniously represents the broad scope of primary care, with 11 domains each represented by a single item: accessibility, advocacy, community context, comprehensiveness, continuity, coordination, family context, goal-oriented care, health promotion, integration, and relationship. Principal axes factor analysis identified a single factor. Factor loadings and corrected item-total correlations were >0.6 in online samples (n = 2,229) and >0.5 in clinical samples (n = 323). Factor scores were fairly normally distributed in online patient samples, and skewed toward higher ratings in point-of-care patient samples. Rasch models showed a broad spread of person and item scores, acceptable item-fit statistics, and little item redundancy. Preliminary concurrent validity analyses supported hypothesized associations.

CONCLUSIONS

The person-centered primary care measure reliably, comprehensively, and parsimoniously assesses the aspects of care thought to represent high-value primary care by patients, clinicians, and payers. The measure is ready for further validation and outcome analyses, and for use in focusing attention on what matters about primary care, while reducing measurement burden.

Developing a New Measure of Primary Care Using the Medical Expenditure Panel Survey

OBJECTIVE

To develop and assess the reliability of a measure of primary care using items from the Medical Expenditure Panel Survey (MEPS), a US representative survey of community-dwelling persons.

METHODS

On the basis of the domains from the literature on primary care characteristics, we identified relevant items within the 2013-2014 MEPS family of surveys. In a sample of primary survey respondents with at least 1 office-based physician visit in the last 12 months, we conducted exploratory factor analysis, retaining items with a factor loading of 0.30 and factors ≥3 items. Using a hold-out sample, internal consistency, reproducibility, and confirmatory factor analyses were performed.

RESULTS

On the basis of 16 care domains, we found 32 candidate items in the MEPS. Factor analyses of data from 4549 persons meeting inclusion criteria (27.6% of the total sample), yielded 3 unique factors involving 24 items. We named these subscales Relationship, Comprehensiveness, and Health Promotion, displaying internal consistency reliability of 0.86, 0.78, and 0.69, respectively. Confirmatory factor analysis corroborated the stability of the exploratory findings in the hold out sample. Sensitivity analyses showed robustness to differences in underlying correlation structure, alternative approach to missing data, and extension to indirect survey respondents.

CONCLUSIONS

The MEPS Primary Care measure with 3 subscales is reliable and may be useful in conducting primary care health services and outcomes research in the rich MEPS dataset. Further validation is needed, and is described in a companion paper.

Factors Associated With Loss of Usual Source of Care Among Older Adults

PURPOSE

Access to a usual source of care (USC) is associated with better preventive health and chronic disease treatment. Although most older adults have a USC, loss of USC, and factors associated with loss of USC, have not previously been examined.

METHODS

We followed 7,609 participants of the National Health and Aging Trends Study annually for up to 6 years (2011-2016). Discrete time-to-event techniques and pooled logistic regression were used to identify demographic, clinical, and social factors associated with loss of USC.

RESULTS

Ninety-five percent of older adults reported having a USC in 2011, of whom 5% subsequently did not. Odds of losing a USC were higher among older adults with unmet transportation needs (adjusted odds ratio [aOR] 1.67), who moved to a new residence (aOR 2.08), and who reported depressive symptoms (aOR 1.40). Odds of losing a USC were lower for those who had ≥4 chronic conditions (vs 0-1; aOR 0.42) and with supplemental (aOR 0.52) or Medicaid (aOR 0.67) insurance coverage.

CONCLUSIONS

We identified factors associated with older adults' loss of a USC. Potentially modifiable factors, such as access to transportation and supplemental insurance, deserve further investigation to potentially assist older adults with continuous access to care.

Off to the Right Start: Well-Child Visit Attendance Among Health Center Users

INTRODUCTION

This study examines correlates of past-year well-child visit attendance, reasons for choosing to receive care at a health center, and patient experience among pediatric federally qualified health center users.

METHOD

This observational study used cross-sectional 2009 Health Center Patient Survey data. Descriptive statistics, bivariate analysis, and multivariable models were utilized.

RESULTS

This study found that 83.0% of children who visited a health center in the past year had a well-child visit in the past year and 88.5% had a usual source of care, with no disparities based on race/ethnicity or insurance status. A usual source of care, especially a health center, enhanced well-child visit attendance. The top reasons for seeking care at a health center include convenience (31.6%), quality (24.5%), accessibility (17.7%), and co-located nonmedical services (11.5%).

DISCUSSION

Well-child visit attendance is high but there is room for improvement, particularly among patients who lack a usual source of care.

Predictors of Age of Diagnosis for Children with Autism Spectrum Disorder: The Role of a Consistent Source of Medical Care, Race, and Condition Severity

Having a consistent source of medical care may facilitate diagnosis of autism spectrum disorders (ASD). This study examined predictors of age of ASD diagnosis using data from the 2011-2012 National Survey of Children's Health. Using multiple linear regression analysis, age of diagnosis was predicted by race, ASD severity, having a consistent source of care (CSC), and the interaction between these variables after controlling for birth cohort, birth order, poverty level, parental education, and health insurance. While African American children were diagnosed earlier than Caucasians, this effect was moderated by ASD severity and CSC. Having a CSC predicted earlier diagnosis for Caucasian but not African American children. Both physician and parent behaviors may contribute to diagnostic delays in minority children.

Disparities in access to preventive health care services among insured children in a cross sectional study

Children with insurance have better access to care and health outcomes if their parents also have insurance. However, little is known about whether the type of parental insurance matters. This study attempts to determine whether the type of parental insurance affects the access to health care services of children.I used data from the 2009-2013 Medical Expenditure Panel Survey and estimated multivariate logistic regressions (N = 26,152). I estimated how family insurance coverage affects the probability that children have a usual source of care, well-child visits in the past year, unmet medical and prescription needs, less than 1 dental visit per year, and unmet dental needs.Children in families with mixed insurance (child publicly insured and parent privately insured) were less likely to have a well-child visit than children in privately insured families (odds ratio = 0.86, 95% confidence interval 0.76-0.98). When restricting the sample to publicly insured children, children with privately insured parents were less likely to have a well-child visit (odds ratio = 0.82, 95% confidence interval 0.73-0.92), less likely to have a usual source of care (odds ratio = 0.79, 95% confidence interval 0.67-0.94), and more likely to have unmet dental needs (odds ratio = 1.68, 95% confidence interval 1.10-2.58).Children in families with mixed insurance tend to fare poorly compared to children in publicly insured families. This may indicate that children in these families may be underinsured. Expanding parental eligibility for public insurance or subsidizing private insurance for children would potentially improve their access to preventive care.

Understanding how low-income families prioritize elements of health care access for their children via the optimal care model

Background

Insurance coverage alone does not guarantee access to needed health care. Few studies have explored what “access” means to low-income families, nor have they examined how elements of access are prioritized when availability, affordability, and acceptability are not all achievable. Therefore, we explored low-income parents’ perspectives on accessing health care.

Methods

In-depth interviews with a purposeful sample of 29 Oregon parents who responded to a previously administered statewide survey about health insurance. Transcribed interviews were analyzed by a multidisciplinary team using a standard iterative process.

Results

Parents highlighted affordability and limited availability as barriers to care; a continuous relationship with a health care provider helped them overcome these barriers. Parents also described the difficult decisions they made between affordability and acceptability in order to get the best care they could for their children. We present a new conceptual model to explain these experiences accessing care with health insurance: the Optimal Care Model. The model shows a transition from optimal care to a breaking point where affordability becomes the driving factor, but the care is perceived as unacceptable because it is with an unknown provider.

Conclusions

Even when covered by health insurance, low-income parents face barriers to accessing health care for their children. As the Affordable Care Act and other policies increase coverage options across the United States, many Americans may experience similar barriers and facilitators to health care access. The Optimal Care Model provides a useful construct for better understanding experiences that may be encountered when the newly insured attempt to access available, acceptable, and affordable health care services.

Insurance coverage and anticipatory guidance: are Hispanic children at a disadvantage?

We examined pediatric insurance status and receipt of weight-related anticipatory guidance in the 2008-2010 Medical Expenditures Panel Survey (n = 12,438). Hispanic children were more likely than white children to report diet and exercise counseling, regardless of insurance. Given the risks of overweight and obesity among Hispanic children, these findings are promising.

Medical home quality and readmission risk for children hospitalized with asthma exacerbations

OBJECTIVE

The medical home likely has a positive effect on outpatient outcomes for children with asthma. However, no information is available regarding the impact of medical home quality on health care utilization after hospitalizations. We sought to explore the relationship between medical home quality and readmission risk in children hospitalized for asthma exacerbations.

METHODS

We enrolled 601 children, aged 1 to 16 years, hospitalized for an acute asthma exacerbation at a single pediatric facility that captures >85% of all asthma admissions in an 8-county area. Caregivers completed the Parent's Perception of Primary Care (P3C), a Likert-based, validated survey. The P3C yields a total score of medical home quality and 6 subscale scores assessing continuity, access, contextual knowledge, comprehensiveness, communication, and coordination. Asthma readmission events were prospectively collected via billing data. Hazards of readmission were calculated by using Cox proportional hazards adjusting for chronic asthma severity and key measures of socioeconomic status.

RESULTS

Overall P3C score was not associated with readmission. Among the subscale comparisons, only children with lowest access had a statistically increased readmission risk compared with children with the best access. Subgroup analysis revealed that children with private insurance and good access had the lowest rates of readmission within a year compared with other combinations of insurance and access.

CONCLUSIONS

Among measured aspects of medical home in a cohort of hospitalized children with asthma, having poor access to a medical home was the only measure associated with increased readmission. Improving physician access for children with asthma may lower hospital readmission.

The effects of health insurance and a usual source of care on a child's receipt of health care

INTRODUCTION

Although recent health care reforms will expand insurance coverage for U.S. children, disparities regarding access to pediatric care persist, even among the insured. We investigated the separate and combined effects of having health insurance and a usual source of care (USC) on children's receipt of health care services.

METHODS

We conducted secondary analysis of the nationally representative 2002-2007 Medical Expenditure Panel Survey data from children (≤ 18 years of age) who had at least one health care visit and needed any additional care, tests, or treatment in the preceding year (n = 20,817).

RESULTS

Approximately 88.1% of the study population had both a USC and insurance; 1.1% had neither one; 7.6% had a USC only, and 3.2% had insurance only. Children with both insurance and a USC had the fewest unmet needs. Among insured children, those with no USC had higher rates of unmet needs than did those with a USC.

DISCUSSION

Expansions in health insurance are essential; however, it is also important for every child to have a USC. New models of practice could help to concurrently achieve these goals.

Understanding the Gap in Primary Care Access and Use Between Teens and Younger Children

Primary health care use among teenagers falls short of clinical recommendations and consistently lags behind that of younger children. Using the Medical Expenditure Panel Survey, the authors explore three explanations for this age-related gap: family composition, parental awareness of children’s health care needs, and the relative role of predisposing, enabling, and need-based factors for teens and younger children. Teenagers are 64% more likely to have no usual source of care and 25% more likely to have had no health care visit in the prior year relative to younger children. The gap narrows in families with children from both age-groups and among children with special health care needs. The largest disparity in primary care access exists between teens in families with no younger sibling(s) and younger children in families with no teen(s). A resolution to the age-related access gap will likely require understanding of, and intervention into, family-level determinants of poor access.

Is health insurance enough? A usual source of care may be more important to ensure a child receives preventive health counseling

Despite the promise of expanded health insurance coverage for children in the United States, a usual source of care (USC) may have a bigger impact on a child's receipt of preventive health counseling. We examined the effects of insurance versus USC on receipt of education and counseling regarding prevention of childhood injuries and disease. We conducted secondary analyses of 2002-2006 data from a nationally-representative sample of child participants (≤17 years) in the Medical Expenditure Panel Survey (n = 49,947). Children with both insurance and a USC had the lowest rates of missed counseling, and children with neither one had the highest rates. Children with only insurance were more likely than those with only a USC to have never received preventive health counseling from a health care provider regarding healthy eating (aRR 1.21, 95% CI 1.12-1.31); regular exercise (aRR 1.06, 95% CI 1.01-1.12), use of car safety devices (aRR 1.10, 95% CI 1.03-1.17), use of bicycle helmets (aRR 1.11, 95% CI 1.05-1.18), and risks of second hand smoke exposure (aRR 1.12, 95% CI 1.04-1.20). A USC may play an equally or more important role than insurance in improving access to health education and counseling for children. To better meet preventive counseling needs of children, a robust primary care workforce and improved delivery of care in medical homes must accompany expansions in insurance coverage.

The case for synergy between a usual source of care and health insurance coverage

BACKGROUND

In 2010, the United States (US) passed health insurance reforms aimed at expanding coverage to the uninsured. Yet, disparities persist in access to health care services, even among the insured.

OBJECTIVE

To examine the separate and combined association between having health insurance and/or a usual source of care (USC) and self-reported receipt of health care services.

DESIGN/SETTING

Two-tailed, chi-square analyses and logistic regression models were used to analyze nationally representative pooled 2002-2007 data from the Medical Expenditure Panel Survey (MEPS).

PARTICIPANTS

US adults (≥18 years of age) in the MEPS population who had at least one health care visit and who needed any care, tests, or treatment in the past year (n = 62,067).

MAIN OUTCOME MEASURES

We assessed the likelihood of an adult reporting unmet medical needs; unmet prescription needs; a problem getting care, tests, or treatment; and delayed care based on whether each individual had health insurance, a USC, both, or neither one.

KEY RESULTS

Among adults who reported a doctor visit and a need for services in the past year, having both health insurance and a USC was associated with the lowest percentage of unmet medical needs, problems and delays in getting care while having neither one was associated with the highest unmet medical needs, problems and delays in care. After adjusting for potentially confounding covariates (age, race, ethnicity, employment, geographic residence, education, household income as a percent of federal poverty level, health status, and marital status), compared with insured adults who also had a USC, insured adults without a USC were more likely to have problems getting care, tests or treatment (adjusted relative risk [aRR] 1.27; 95% confidence interval [CI] 1.18-1.37); and also had a higher likelihood of experiencing a delay in urgent care (aRR 1.12; 95% CI 1.05-1.20).

CONCLUSIONS

Amidst ongoing health care reform, these findings suggest the important role that both health insurance coverage and a usual source of care may play in facilitating individuals' access to care.

Electronic health records vs Medicaid claims: completeness of diabetes preventive care data in community health centers

PURPOSE

Electronic Health Record (EHR) databases in community health centers (CHCs) present new opportunities for quality improvement, comparative effectiveness, and health policy research. We aimed (1) to create individual-level linkages between EHR data from a network of CHCs and Medicaid claims from 2005 through 2007; (2) to examine congruence between these data sources; and (3) to identify sociodemographic characteristics associated with documentation of services in one data set vs the other.

METHODS

We studied receipt of preventive services among established diabetic patients in 50 Oregon CHCs who had ever been enrolled in Medicaid (N = 2,103). We determined which services were documented in EHR data vs in Medicaid claims data, and we described the sociodemographic characteristics associated with these documentation patterns.

RESULTS

In 2007, the following services were documented in Medicaid claims but not the EHR: 11.6% of total cholesterol screenings received, 7.0% of total influenza vaccinations, 10.5% of nephropathy screenings, and 8.8% of tests for glycated hemoglobin (HbA(1c)). In contrast, the following services were documented in the EHR but not in Medicaid claims: 49.3% of cholesterol screenings, 50.4% of influenza vaccinations, 50.1% of nephropathy screenings, and 48.4% of HbA(1c) tests. Patients who were older, male, Spanish-speaking, above the federal poverty level, or who had discontinuous insurance were more likely to have services documented in the EHR but not in the Medicaid claims data.

CONCLUSIONS

Networked EHRs provide new opportunities for obtaining more comprehensive data regarding health services received, especially among populations who are discontinuously insured. Relying solely on Medicaid claims data is likely to substantially underestimate the quality of care.

Medical home disparities between children with public and private insurance

OBJECTIVE

To compare the prevalence of a medical home for children with public versus private insurance and identify components of the medical home that contribute to any differences.

METHODS

We performed a secondary data analysis of the 2007 National Survey of Children's Health. A medical home was defined as meeting each of 5 components: 1) usual source of care; 2) personal doctor/nurse; 3) family-centered care; 4) care coordination, if needed; and 5) no problems getting a referral, if needed. We estimated the national prevalence of the medical home and its components for children with public versus private insurance. Comparisons were made using logistic regression, unadjusted and adjusted for sociodemographic factors.

RESULTS

A total of 67% of privately insured children met all 5 components of the medical home, compared with only 45% of publicly insured children (P < .001). The gap in medical home prevalence between public and private groups remained significant after controlling for sociodemographic characteristics (public vs private adjusted odds ratio [AOR] 0.82; 95% confidence interval [95% CI] 0.73-0.92). Over 90% of children in both groups reported having a usual source of care and a personal doctor/nurse. Only 58% of publicly insured children reported family-centered care, compared with 76% of privately insured children (P < .001). This difference was significant after adjustment for sociodemographic characteristics (public vs private AOR 0.87; 95% CI 0.77-0.99).

CONCLUSIONS

Significant medical home disparities exist between publicly and privately insured children, driven primarily by disparities in family-centered care. Efforts to promote the medical home must recognize and address determinants of family-centered care.

The medical home, preventive care screenings, and counseling for children: evidence from the Medical Expenditure Panel Survey

OBJECTIVE

Little is known about the role of the medical home in promoting essential preventive health care services in the general pediatric population. This study examined associations between having a medical home and receipt of health screenings and anticipatory guidance.

METHODS

We conducted a cross-sectional analysis of the 2004-2006 Medical Expenditure Panel Survey (MEPS). Our sample included 21 055 children aged 0 to 17 years who visited a health care provider in the year prior to the survey. A binary indicator of the medical home was developed from 22 questions in MEPS, reflecting 4 of the 7 American Academy of Pediatrics' recommended components of the medical home: accessible, family-centered, comprehensive, and compassionate care. Multivariable logistic regression was used to examine the association between the medical home and receipt of specific health screenings and anticipatory guidance, controlling for confounding variables.

RESULTS

Approximately 49% of our study sample has a medical home. The medical home, defined when the usual source of care is a person or facility, is significantly associated with 3 health screenings (ie, weight, height, and blood pressure) and several anticipatory guidance topics (ie, advice about dental checkups, diet, exercise, car and bike safety), with odds ratios ranging from 1.26 to 1.54.

CONCLUSIONS

The medical home is associated with increased odds of children receiving some health screenings and anticipatory guidance. The medical home may provide an opportunity to improve the delivery of these services for children.

Beyond insurance coverage: usual source of care in the treatment of hypertension and hypercholesterolemia. Data from the 2003-2006 National Health and Nutrition Examination Survey

BACKGROUND

Expanding insurance coverage, while necessary, may not be sufficient to ensure high-quality care for adults with cardiovascular disease. We sought to examine the association between having a usual source of care (USOC) and receiving medication treatment of hypertension and hypercholesterolemia.

METHODS

Using the 2003-2006 National Health and Nutrition Examination Survey, we categorized USOC (a place to go when sick or need medical advice) and insurance status in adults >or=35 years old with an indication for medication treatment of hypertension (n = 3,142) and hypercholesterolemia (n = 1,134), determined using the Joint National Committee 7 and Adult Treatment Panel III recommendations, respectively. Multivariable logistic regression modeling was used to determine the independent effect of USOC on receiving treatment of hypertension and hypercholesterolemia, controlling for age, sex, race/ethnicity, insurance status, and comorbidities. Separate multivariable models were examined stratified by insurance status.

RESULTS

Among subjects with an indication for treatment of hypertension and hypercholesterolemia, 32.4% and 42.0% were untreated, respectively. When compared with adults with a USOC, adults without a USOC were more likely to be untreated for hypertension (adjusted prevalence ratio [aPR] 2.43, 95% CI 1.88-2.85) and hypercholesterolemia (aPR 1.79, 95% CI 1.31-2.13). In stratified analyses among subjects with insurance, no USOC remained associated with being untreated (hypertension, aPR 2.58, 95% CI 1.88-3.08; hypercholesterolemia, aPR 1.65, 95% CI 0.97-2.18).

CONCLUSIONS

Absence of a USOC was associated with being untreated for hypertension and hypercholesterolemia, even among individuals with insurance, suggesting that efforts to improve chronic disease management should also facilitate access to a regular source of care.
