Interpretation of coefficients in segmented regression for interrupted time series analyses.

Background: Segmented regression, a common model for interrupted time series (ITS) analysis, primarily utilizes two equation parametrizations. Interpretations of coefficients vary between the two segmented regression parametrizations, leading to occasional user misinterpretations. Methods: To illustrate differences in coefficient interpretation between two common parametrizations of segmented regression in ITS analysis, we derived analytical results and present an illustration evaluating the impact of a smoking regulation policy in Italy using a publicly accessible dataset. Estimated coefficients and their standard errors were obtained using two commonly used parametrizations for segmented regression with continuous outcomes. We clarified coefficient interpretations and intervention effect calculations. Results: Our investigation revealed that both parametrizations represent the same model. However, due to differences in parametrization, the immediate effect of the intervention is estimated differently under the two approaches. The key difference lies in the interpretation of the coefficient related to the binary indicator for intervention implementation, impacting the calculation of the immediate effect. Conclusions: Two common parametrizations of segmented regression represent the same model but have different interpretations of a key coefficient. Researchers employing either parametrization should exercise caution when interpreting coefficients and calculating intervention effects.

Effectiveness and feasibility of three types of parent reminders to increase adolescent human papillomavirus (HPV) vaccination.

Parent reminders have produced modest improvements in human papillomavirus (HPV) vaccination among adolescents. However, little prior research has compared the effectiveness and feasibility of different HPV reminder types in resource-limited settings. We conducted a quasi-experimental study (2016-2017) to evaluate the effectiveness of three parent reminder types (mailed letters, robocalls, text messages) on next-dose HPV vaccine receipt among 12-year-olds in a large Federally Qualified Health Center in Los Angeles County. Six clinics were matched into three pairs: randomly assigning one clinic within each pair to intervention and control. Intervention clinics were randomly assigned to deliver one of the three parent reminder types. We calculated rates of next-dose vaccine receipt and assessed intervention effects using logistic regression models. We calculated the proportion of each type of reminder successfully delivered as a feasibility measure. The study sample comprised 877 12-year-olds due for an HPV vaccine dose (47% female, >85% Latino). At 4-month follow-up, 23% of intervention patients received an HPV vaccine dose compared to only 12% of control patients. Overall, receipt of any reminder increased rates of the next-needed HPV vaccine compared to usual care (p = 0.046). Significant improvements were observed for text reminders (p = 0.036) and boys (p = 0.006). Robocalls were the least feasible reminder type. Text message reminders are feasible and effective for promoting HPV vaccination. Future research is needed to assess the effectiveness and feasibility of reminders compared to other vaccine promotion strategies.

Impact of a Multi-Level, Multi-Component, System Intervention on HPV Vaccination in a Federally Qualified Health Center.

BACKGROUND: Human papillomavirus (HPV) vaccines can significantly reduce the burden of HPV-associated cancers, but remain underutilized. We evaluated a multi-component, system-level intervention to improve HPV vaccination in a large Federally Qualified Health Center (FQHC) that serves a primarily low income Latino population. METHODS: From January 2015 through March 2017, we evaluated the effectiveness of a multi-component, system-level intervention to improve HPV vaccination rates in eight clinics randomly assigned to study condition (four intervention, four usual care). The intervention included parent reminders for HPV vaccine series completion, provider training, clinic-level audit and feedback, and workflow modifications to reduce missed opportunities for vaccination. Using a difference-in-differences approach, we compared HPV vaccination rates among patients, ages 11 to 17 during a 12-month preintervention period and a 15-month intervention period. Linear mixed models were used to estimate intervention effects on vaccine initiation and completion. RESULTS: The sample included approximately 15,000 adolescents each quarter (range 14,773-15,571; mean age 14 years; 51% female, 88% Latino). A significantly greater quarterly increase in HPV vaccine initiation was observed for intervention compared with usual care clinics (0.75 percentage point greater increase, P < 0.001), corresponding to 114 additional adolescents vaccinated per quarter. The intervention led to a greater increase in HPV vaccine completion rates among boys (0.65 percentage point greater increase, P < 0.001), but not girls. CONCLUSIONS: Our system-level intervention was associated with modest improvements in HPV vaccine initiation overall and completion among boys. IMPACT: Study findings have implications for reducing HPV-related cancers in safety net populations.

Increasing HPV Vaccination among Low-Income, Ethnic Minority Adolescents: Effects of a Multicomponent System Intervention through a County Health Department Hotline.

BACKGROUND: Introduction of the human papillomavirus (HPV) vaccine in 2006 was a game-changing advance in cancer control. Despite the vaccine's potential cancer prevention benefits, uptake remains low. We utilized a randomized design to evaluate a multicomponent intervention to improve HPV vaccine uptake among low-income, ethnic minority adolescents seeking services through a county health department telephone hotline. METHODS: Hotline callers who were caregivers of never-vaccinated adolescents (11-17 years) were randomized by call-week to intervention or control conditions. The intervention included brief telephone and print education, delivered in multiple languages, and personalized referral to a low-cost/free vaccine provider. Participants completed baseline (n = 238), 3-month (n = 215), and 9-month (n = 204) telephone follow-up surveys. RESULTS: HPV vaccine initiation rates increased substantially by 9-month follow-up overall, although no differences were observed between intervention and control groups (45% vs. 42%, respectively, P > 0.05). We also observed significant improvements in perceived HPV risk, barriers to vaccination, and perceived knowledge in both study conditions (P < 0.05). CONCLUSIONS: A low-intensity county hotline intervention did not produce a greater increase in HPV vaccination rates than routine practice. However, 44% of unvaccinated adolescents in both conditions received at least one dose of the vaccine, which can be viewed as a successful public health outcome. Future studies should evaluate more intensive interventions that address accessing and utilizing services in complex safety net settings. IMPACT: Study results suggest the need for investigators to be aware of the potential priming effects of study participation, which may obscure the effect of low-intensity interventions.

Human papillomavirus (HPV) vaccination in the transition between adolescence and adulthood.

PURPOSE: Young adulthood is characterized by changes in health care decision-making, insurance coverage, and sexual risk. Although the human papillomavirus (HPV) vaccine is now approved for adults up to age 45, and catch-up vaccination is currently recommended up through age 26, vaccination rates remain low in young adults. This study explored perspectives on HPV vaccination among young adults receiving care at the student health center of a large public university. METHODS: We conducted semi-structured interviews (n = 27) and four focus groups with female and male undergraduate and graduate students (n = 18) and semi-structured interviews with health care providers (n = 6). Interviews and focus groups explored perceived risk of HPV infection, benefits of the HPV vaccine, and motivations for and barriers to HPV vaccination. RESULTS: Many young adults cited their parents' views and recommendations from medical providers as influential on their decision-making process. Students perceived that cervical cancer prevention was a main benefit of the HPV vaccine and sexual activity was a risk factor for HPV infection. Students often lacked knowledge about the vaccine's benefits for males and expressed some concerns about the safety and side effects of a vaccine perceived as new. Logistical barriers to vaccination included uncertainty over vaccination status and insurance coverage for the vaccine, and concerns about balancing the vaccine schedule with school obligations. Providers' vaccine recommendations were impacted by health system factors, including clinical infrastructure, processes for recommending and documenting vaccination, and office visit priorities. Suggested vaccination promotion strategies included improving the timing and messaging of outreach efforts on campus and bolstering clinical infrastructure. CONCLUSIONS: Although college may be an opportune time to reach young adults for HPV vaccination, obstacles including navigating parental influence and independent decision-making, lack of awareness of vaccination status, and numerous logistical and system-level barriers may impede vaccination during this time.

Cancer surveillance and preventive services in a diverse sample of breast and colorectal cancer survivors.

PURPOSE: Cancer survivors diagnosed at an early age remain at risk for cancer recurrence and other chronic diseases. This study assessed engagement in surveillance for recurrence, cancer screening, and other recommended preventive health services among breast and colorectal cancer survivors with early-onset disease (≤ 50 years) who were diagnosed in California. METHODS: Breast and colorectal cancer survivors diagnosed with early-onset cancer between 1999 and 2009 were identified through the California Cancer Registry, the state-based cancer registry, and surveyed. Multivariable regression analyses were used to assess correlates of receipt of cancer surveillance, cancer screening, and other preventive health services. RESULTS: Of the 497 survivors that were invited to participate in the study, 156 completed the survey for a response rate of 31%. The sample was 50 years of age on average (range 32-69 years) with a mean time since diagnosis of 9 years. The majority of the sample (71%) was a racial/ethnic minority (24% Latino, 15% African American, 29% Asian). Overall, 80% received appropriate surveillance for recurrence, and 72% received recommended screening for early detection of other cancers (breast, cervical, colorectal). Increasing age was associated with lower likelihood of early detection screening (adjusted odds ratio (aOR) 0.28, 95% confidence interval (CI) 0.11-0.69), and higher income was associated with a greater likelihood (aOR 4.89, 95% CI 1.62-14.81). Screening rates were highest for blood pressure (96%), cholesterol (86%), and diabetes (81%), followed by dental visits (64%) and flu vaccination (35%). Greater use of recommended preventive health services was associated with increasing age, female sex, higher education level, and having health insurance. CONCLUSIONS: Although the majority of survivors received appropriate surveillance for recurrence, engagement in other preventive health services varied substantially. IMPLICATIONS FOR CANCER SURVIVORS: Efforts are needed to address gaps in the use of recommended cancer screening and preventive health services among cancer survivors, particularly survivors with early-onset disease who may be at increased risk for additional cancers and common chronic conditions over their lifetime.

The Drug Shortage Crisis in the United States: Impact on Cancer Pharmaceutical Safety.

Drug shortages pose a significant public health concern in the United States, and cancer drugs are among those most affected. Shortages present serious safety risks for patients and substantial burden on providers and the healthcare system. Multifaceted drivers of this complex problem include manufacturing disruptions, raw material shortages, regulatory issues, market dynamics, and limited financial incentives that reward quality and production of off-patent drugs. Oncology drugs in short supply have resulted in substitution of less effective or more toxic alternatives, medication errors, and treatment delays, and are especially concerning for medications with no adequate substitute. Consequently, patient outcomes such as disease progression and survival have been adversely affected. Furthermore, emerging gray markets have contributed to cost-prohibitive markups and introduction of counterfeit products that compromise patient safety. The Food and Drug Administration plays a key role in preventing and managing pharmaceutical shortages, largely through regulations requiring early notification of manufacturing interruptions. Other proposed strategies similarly target upstream causes and center on reducing regulatory hurdles for manufacturers and increasing incentives for market entry and quality improvement. Despite progress in preventing supply disruptions, continued exploration of underlying systemic drivers remains critical to informing long-term solutions and alleviating the clinical and economic impact of drug shortages.

Obesity, physical activity, and dietary behaviors in an ethnically-diverse sample of cancer survivors with early onset disease.

PURPOSE: To assess weight status, physical activity, and dietary behaviors in an ethnically-diverse sample of breast and colorectal cancer survivors with early onset disease (≤ 50 years). METHODS: Breast and colorectal cancer survivors, diagnosed between 1999 and 2009 with early-stage cancer diagnosed by 50 years of age, were identified through a population-based cancer registry and surveyed. Descriptive and regression analyses were conducted to characterize the sample and identify correlates of lifestyle behaviors. FINDINGS: The majority of participants (n = 156) were female (83%), insured (84%), and racial/ethnic minorities (29% Asian, 24% Latino, 15% African American). Participants' mean age at response was 50 years and mean time since diagnosis was 9 years. Over half of survivors were overweight or obese. Few participants reported engaging in regular physical activity (31%) and adhering to minimum guidelines for fruit and vegetable consumption (32%). A substantial proportion of survivors consumed fast food in the past week (75%) and nearly half (48%) reported daily consumption of sugar-sweetened beverages. Lower income was associated with inadequate fruit and vegetable intake. Fast food and sugar-sweetened beverage consumption was significantly higher among racial/ethnic minority survivors compared to non-Latino whites. CONCLUSIONS: High prevalence of overweight and suboptimal adherence to recommended nutrition and physical activity behaviors were observed among cancer survivors with early onset disease. Cancer survivors diagnosed at a young age may benefit from targeted interventions to address overweight and suboptimal nutrition and physical activity.

Trends in Cervical Cancer Screening in California's Family Planning Program.

OBJECTIVE: Guidelines recommend 3-year cervical cancer screening intervals to avoid unnecessary invasive procedures; however, regular testing remains critical. We evaluated trends in cervical cancer screening among low-income women receiving family planning-related services and their association with patient and provider characteristics. MATERIALS AND METHODS: Using claims and enrollment data from California's publicly funded family planning program, we identified 540,026 women with a clinician visit at 216 sites between 2011 and 2015. We calculated guideline adherent cervical cancer testing rates for 6-month periods among women aged 21 to 24, 25 to 29, and 30 to 64 years. We also calculated guideline adherent chlamydia testing for women aged 21 to 24 years. RESULTS: Having a 3-year cervical cancer screening test declined for all age groups. The odds of cervical cancer screening declined for women aged 21 to 24 years by an estimated 11% every 6 months (odds ratio [OR] = 0.90, 95% confidence interval [CI] = 0.89-0.90), a significantly greater decline than for the other age groups. Among women aged 21 to 29 years, the decrease was significantly larger for Latina (ratio of ORs = 0.95, 95% CI = 0.95-0.96) and Spanish-speaking (ratio of ORs = 0.95, 95% CI = 0.95-0.96) women compared with non-Latina and non-Spanish-speaking women. A smaller decline was seen for chlamydia screening. CONCLUSIONS: Changes in screening interval guidelines are associated with overall decreased screening. This trend was strongest among women aged 21 to 24 years, even as they continued to be screened appropriately for chlamydia, suggesting many missed opportunities. Efforts to reduce unnecessary cervical cancer screening should be monitored to maintain appropriate screening rates to avoid advanced-stage diagnoses and higher health care costs.

Behavioral and mental health risk factor profiles among diverse primary care patients.

Behavioral and mental health risk factors are prevalent among primary care patients and contribute substantially to premature morbidity and mortality and increased health care utilization and costs. Although prior studies have found most adults screen positive for multiple risk factors, limited research has attempted to identify factors that most commonly co-occur, which may guide future interventions. The purpose of this study was to identify subgroups of primary care patients with co-occurring risk factors and to examine sociodemographic characteristics associated with these subgroups. We assessed 12 behavioral health risk factors in a sample of adults (n=1628) receiving care from nine primary care practices across six U.S. states in 2013. Using latent class analysis, we identified four distinct patient subgroups: a 'Mental Health Risk' class (prevalence=14%; low physical activity, high stress, depressive symptoms, anxiety, and sleepiness), a 'Substance Use Risk' class (29%; highest tobacco, drug, alcohol use), a 'Dietary Risk' class (29%; high BMI, poor diet), and a 'Lower Risk' class (27%). Compared to the Lower Risk class, patients in the Mental Health Risk class were younger and less likely to be Latino/Hispanic, married, college educated, or employed. Patients in the Substance Use class tended to be younger, male, African American, unmarried, and less educated. African Americans were over 7 times more likely to be in the Dietary Risk versus Lower Risk class (OR 7.7, 95% CI 4.0-14.8). Given the heavy burden of behavioral health issues in primary care, efficiently addressing co-occurring risk factors in this setting is critical.

Disparities in parental human papillomavirus (HPV) vaccine awareness and uptake among adolescents.

Trends in HPV vaccine awareness among parents of adolescent girls and boys (ages 13-17) and HPV vaccine uptake (≥1 dose) among girls (ages 13-17) were evaluated in Los Angeles County, California. Between 2007 and 2011, parental HPV vaccine awareness increased from 72% to 77% overall, with significant increases among mothers, Latinos, and respondents with daughters and Medi-Cal insured children. In 2011, parents who were male, older, less educated, Asian/Pacific Islander, and had sons remained significantly less likely to be aware. HPV vaccine initiation among daughters nearly doubled from 25% in 2007 to 48% in 2011, and girls who were older, uninsured, and had access-related barriers showed the largest improvements. In 2011, daughters who were younger and who had older and African American parents were at risk for low uptake. Thus, initiatives targeting male and younger adolescents, culturally-relevant information, and access to vaccination may help to reduce identified disparities.

The Affordable Care Act's Impacts on Access to Insurance and Health Care for Low-Income Populations.

The Patient Protection and Affordable Care Act (ACA) expands access to health insurance in the United States, and, to date, an estimated 20 million previously uninsured individuals have gained coverage. Understanding the law's impact on coverage, access, utilization, and health outcomes, especially among low-income populations, is critical to informing ongoing debates about its effectiveness and implementation. Early findings indicate that there have been significant reductions in the rate of uninsurance among the poor and among those who live in Medicaid expansion states. In addition, the law has been associated with increased health care access, affordability, and use of preventive and outpatient services among low-income populations, though impacts on inpatient utilization and health outcomes have been less conclusive. Although these early findings are generally consistent with past coverage expansions, continued monitoring of these domains is essential to understand the long-term impact of the law for underserved populations.

Public Funds Account for Over 70 Percent of Health Care Spending in California.

In California, personal health care expenditures are estimated to total more than $367 billion in 2016. Approximately 71 percent of these expenditures will be paid for with public funds (i.e., taxpayer dollars). This estimated contribution of public funds to health care expenditures is much higher than estimates that include only major health insurance programs such as Medicare and Medicaid. Several additional public funding sources also contribute to health care expenditures in the state, including government spending for public employee health benefits, tax subsidies for employer-sponsored insurance and the Affordable Care Act (ACA) insurance exchange, and county health care expenditures. As health care reform continues to take effect, it will be important to monitor the public versus private contributions to state health care expenditures to ensure that funds are being distributed both efficiently and equitably.

Patient Navigators: Agents of Creating Community-Nested Patient-Centered Medical Homes for Cancer Care.

Patient navigation is an internationally utilized, culturally grounded, and multifaceted strategy to optimize patients' interface with the health-care team and system. The DuPage County Patient Navigation Collaborative (DPNC) is a campus-community partnership designed to improve access to care among uninsured breast and cervical cancer patients in DuPage County, IL. Importantly, the DPNC connects community-based social service delivery with the patient-centered medical home to achieve a community-nested patient-centered medical home model for cancer care. While the patient navigator experience has been qualitatively documented, the literature pertaining to patient navigation has largely focused on efficacy outcomes and program cost effectiveness. Here, we uniquely highlight stories of women enrolled in the DPNC, told from the perspective of patient navigators, to shed light on the myriad barriers that DPNC patients faced and document the strategies DPNC patient navigators implemented.

Delays in Cancer Care Among Low-Income Minorities Despite Access.

INTRODUCTION: Narrowing the racial/ethnic and socioeconomic disparities in breast and cervical cancer requires an in-depth understanding of motivation for adherence to cancer screening and follow-up care. To inform patient-centered interventions, this study aimed to identify reasons why low-income women adhered to or delayed breast or cervical cancer screening, follow-up and treatment despite access to cancer care-related services. METHODS: Semistructured qualitative interviews were conducted among women with access to cancer care-related services receiving care at an academic cancer center, federally qualified health centers, or free clinics in the Chicago metropolitan area. Transcripts were coded and analyzed for themes related to rationales for adherence. RESULTS: Among 138 participants, most were African American (46%) or Hispanic (36%), English speaking (70%), and between ages 41 and 65 years (64%). Primary drivers of nonadherence included lack of knowledge of resources, denial or fear, competing obligations, and embarrassment. Facilitators included abnormality identification, patient activation, provider-initiated actions, and motivation from family or friends. CONCLUSIONS: Interventions targeting increased adherence to care among low-income and ethnic minority women should direct efforts to proactive, culturally and patient-informed education that enables patients to access resources and use the health care system, address misconceptions about cancer, ensure health care providers' communication of screening guidelines, and leverage the patient's social support network.

Evaluating a bilingual patient navigation program for uninsured women with abnormal screening tests for breast and cervical cancer: implications for future navigator research.

OBJECTIVES: The DuPage Patient Navigation Collaborative evaluated the Patient Navigation Research Program (PNRP) model for uninsured women receiving free breast or cervical cancer screening through the Illinois Breast and Cervical Cancer Program in DuPage County, Illinois. METHODS: We used medical records review and patient surveys of 477 women to compare median follow-up times with external Illinois Breast and Cervical Cancer Program and Chicago PNRP benchmarks of performance. We examined the extent to which we mitigated community-defined timeliness risk factors for delayed follow-up, with a focus on Spanish-speaking participants. RESULTS: Median follow-up time (29.0 days for breast and 56.5 days for cervical screening abnormalities) compared favorably to external benchmarks. Spanish-speaking patients had lower health literacy, lower patient activation, and more health care system distrust than did English-speaking patients, but despite the prevalence of timeliness risk factors, we observed no differences in likelihood of delayed (> 60 days) follow-up by language. CONCLUSIONS: Our successful replication and scaling of the PNRP navigation model to DuPage County illustrates a promising approach for future navigator research.

Factors associated with HPV awareness among mothers of low-income ethnic minority adolescent girls in Los Angeles.

Among caregivers of adolescent girls, awareness of human papillomavirus (HPV) is strongly associated with vaccine uptake. Little is known, however, about the predictors of HPV awareness among low-income ethnic minority groups in the U.S. The purpose of this study is to understand demographic factors associated with HPV awareness among low-income, ethnic minority mothers in Los Angeles County. We conducted a cross-sectional study of caregivers of adolescent girls through the Los Angeles County Department of Public Health Office of Women's Health's hotline. The majority of the participants were foreign-born (88%), one quarter lacked a usual source of care, and one quarter lacked public or private health insurance for their daughter. We found that one in three participants had never heard of HPV or the vaccine. Mothers that were unaware of HPV were significantly more likely to conduct the interview in a language other than English and to lack health insurance for their daughters. HPV vaccine awareness was much lower in our caregiver sample (61%) than in a simultaneous national survey of caregivers (85%). The associations between lack of awareness and use of a language other than English, as well as lack of health insurance for their daughter indicate the need for HPV vaccine outreach efforts tailored to ethnic minority communities in the U.S.

What women want: patient recommendations for improving access to breast and cervical cancer screening and follow-up.

BACKGROUND: The patient voice remains underrepresented in clinical and public health interventions. To inform interventions that strive to improve access to breast and cervical cancer screening and follow-up among low-income populations, we explored recommendations from low-income women pursuing health care in the safety net. METHODS: Semi-structured interviews were conducted among women receiving follow-up care for an abnormal breast or cervical cancer screening result or a positive cancer diagnosis in federally qualified health centers, free clinics, or an academic cancer center in the Chicago metropolitan area. FINDINGS: Of the 138 women interviewed in the parent study, 52 women provided recommendations for improving access to screening and follow-up care. Most were between 41 and 65 years old (62%) and African American (60%) or White (25%). Recommendations included strengthening community-based health education with more urgent messaging, strategic partnerships, and active learning experiences to increase patient engagement, which women regarded as a key driver of access. Women also suggested increasing access by way of changes to health care delivery systems and policy, including more direct patient-provider and patient-clinic communications, addressing delays caused by high patient volume, combining preventive services, expanding insurance coverage, and adjusting screening guidelines. CONCLUSIONS: This exploratory study demonstrates important insights from the patient lens that may help to increase the acceptability and efficacy of community and clinical interventions aimed at improving access to breast and cervical cancer screening and follow-up. Further research is needed to identify appropriate integration of patient input into interventions, practice, and policy change.

Community-campus partnership in action: lessons learned from the DuPage County Patient Navigation Collaborative.

BACKGROUND: Using community-based participatory research (CBPR), the DuPage County Patient Navigation Collaborative (DPNC) developed an academic campus-community research partnership aimed at increasing access to care for underserved breast and cervical cancer patients within DuPage County, a collar county of Chicago. Given rapidly shifting demographics, targeting CBPR initiatives among underserved suburban communities is essential. OBJECTIVES: To discuss the facilitating factors and lessons learned in forging the DPNC. METHODS: A patient navigation collaborative was formed to guide medically underserved women through diagnostic resolution and if necessary, treatment, after an abnormal breast or cervical cancer screening. LESSONS LEARNED: Facilitating factors included (1) fostering and maintaining collaborations within a suburban context, (2) a systems-based participatory research approach, (3) a truly equitable community-academic partnership, (4) funding adaptability, (5) culturally relevant navigation, and (6) emphasis on co-learning and capacity building. CONCLUSIONS: By highlighting the strategies that contributed to DPNC success, we envision the DPNC to serve as a feasible model for future health interventions.

Access to care outcomes: a telephone interview study of a suburban safety net program for the uninsured.

Access DuPage (AD) currently provides primary care for about 14,000 low income, uninsured residents of suburban DuPage County, IL, an area with a very limited healthcare safety net infrastructure. A telephone interview survey evaluated health care utilization, satisfaction, and health status outcomes and compared recent enrollees to individuals in the program for at least 1 year. Sequential new AD enrollees (n = 158) were asked about the previous year when uninsured, while randomly selected established AD enrollees (n = 135) were asked the same questions about the previous year when actively enrolled in AD. Established enrollees reported being more likely to get 'any kind of tests or treatment' (96.3 vs. 46.2 %, p < 0.0001), fewer cost (78.5 vs. 21.3 %, p < 0.0001) and transportation barriers to care, more preventive and mental health services, and better self-management care. However, established enrollees also reported 14 % greater use of hospital inpatient and 9 % greater use of emergency room care, as well as continued difficulty in accessing needed specialty and dental care services. Despite more (diagnosed) conditions, established enrollees were over 2.5 times more likely to report good to excellent health status and over three times more likely to rate their satisfaction with health care as good to excellent. Findings illustrate the substantial benefits of assuring access to care for the uninsured, but do not reflect immediate savings from reduced hospital utilization. Access to care programs will be an important tool to address the needs of the 30 million people who will continue to be uninsured in the United States.
