Primary care appointment availability for new Medicaid patients increased after Medicaid expansion in Michigan

State-Level Medicaid Reimbursement and Imaging Utilization by Medicaid and Children's Health Insurance Program Patients

PURPOSE

To determine if relative Medicaid-to-Medicare reimbursement rates are associated with patient imaging utilization.

METHODS

This cross-sectional study estimated the association of diagnostic imaging utilization with the state-level Medicaid-to-Medicare reimbursement ratio (MMRR) of professional payments. State-specific reimbursement ratios were computed for each imaging modality. Logistic regression was used to estimate the likelihood of having imaging, and gamma regression was used to estimate the average number of imaging studies for those with imaging. These models were performed for each gender-modality combination controlling for patient characteristics.

RESULTS

Among 48,835,765 Medicaid patients, 54.3% were women. The median MMRR was 0.82 (interquartile range [IQR]: 0.73-0.94) for CT, 0.87 (IQR: 0.76-1.01) for MR, 0.76 (IQR: 0.69-0.99) for nuclear medicine (NM), 0.85 (IQR: 0.73-1.09) for ultrasound, and 0.82 (IQR: 0.74-0.97) for radiography or fluoroscopy (XR). The probability of having imaging was 25.9% for CT, 25.9% for MR, 21.4% for ultrasound, and 31.8% for XR higher at 75th percentile of the MMRR distribution compared with the 25th percentile (P < .001). For those with imaging, the mean number of imaging studies received was associated with 5.7% fewer studies for NM at the 75th percentile compared with the 25th percentile (P < .001), although there was no difference for other modalities.

CONCLUSIONS

Medicaid payments are related to imaging utilization. A higher MMRR is associated with a substantially increased likelihood of Medicaid patients receiving CT, MR, ultrasound, and XR imaging but no difference in the amount of imaging studies received for those with imaging for these modalities.

Reconsidering and Measuring Patient Access in Medicaid

This JAMA Forum discusses the ways that policymakers can use different metrics that are more meaningful to patients when measuring patient access to treatment in the Medicaid program.

Private health insurance in the United States and Sweden: A comparative review

Background and Aims

The United States of America and Sweden both contain a public and private component to their healthcare systems. While both countries spend a similar amount per capita on public healthcare expenditures, the United States spends significantly more in the private healthcare sector. Sweden has a social democratic model of health care, and given its identity as a welfare state, private health insurance providers have a small and nuanced role.

Methods

This paper was completed after searches were queried for "Sweden," "United States," and variants of the words "insurance," "public," "private," "Medicare," "Medicaid," "public," and "costs." A preliminary search in May 2022, yielded 78 articles, of which 45 were ultimately considered relevant for this review. Inclusion criteria consisted of English language articles, topic relevance, and verification of MEDLINE-indexed journals. These searches were performed in PubMed, Google Scholar, Embase, and Cochrane. Summary findings of these searches are compiled in this review.

Results

Sweden guarantees low-cost appropriate care to all citizens with equitable access; however, drawbacks of its system include high financial burden, lack of primary care infrastructure, as well as geographical and socioeconomic inequities. On the other hand, the United States' healthcare system is built around the private sector with public health insurance reserved only for the most vulnerable patient populations.

Conclusion

Our goal is to provide an overview, compare the role of private health insurance in both countries, and highlight policies that have had beneficial effects in each nation. Possible solutions to the drawbacks of each nation's health insurance policies could be addressed by additional support to Sweden's vulnerable population by developing a program similar to the US' Medicare Advantage program. Conversely, the United States may benefit from increasing access to public health insurance, especially in instances where families face unemployment.

Association of Medicaid expansion with dental emergency department visits overall and by states' Medicaid dental benefits provision

BACKGROUND

Evidence on the association of Medicaid expansion with dental emergency department (ED) utilization is limited, while even less is known on policy-related changes in dental ED visits by Medicaid programs' dental benefits generosity. The objective of this study was to estimate the association of Medicaid expansion with changes in dental ED visits overall and by states' benefits generosity.

METHODS

We used the Healthcare Cost and Utilization Project's Fast Stats Database from 2010 to 2015 for non-elderly adults (19 to 64 years of age) across 23 States, 11 of which expanded Medicaid in January 2014 while 12 did not. Difference-in-differences regression models were used to estimate changes in dental-related ED visits overall and further stratified by states' dental benefit coverage in Medicaid between expansion and non-expansion States.

RESULTS

After 2014, dental ED visits declined by 10.9 [95% confidence intervals (CI): -18.5 to -3.4] visits per 100,000 population quarterly in states that expanded Medicaid compared to non-expansion states. However, the overall decline was concentrated in Medicaid expansion states with dental benefits. In particular, among expansion states, dental ED visits per 100,000 population declined by 11.4 visits (95% CI: -17.9 to -4.9) quarterly in states with dental benefits in Medicaid compared to states with emergency-only or no dental benefits. Significant differences between non-expansion states by Medicaid's dental benefits generosity were not observed [6.3 visits (95% CI: -22.3 to 34.9)].

CONCLUSIONS

Our findings suggest the need to strengthen public health insurance programs with more generous dental benefits to curtail costly dental ED visits.

Early pregnancy confirmation availability at crisis pregnancy centers and abortion facilities in the United States

OBJECTIVES

Crisis pregnancy centers (CPCs) seek to dissuade people from having abortions. Twenty-five states have policies supporting CPCs. We aimed: (1) to characterize access to early pregnancy confirmation at CPCs compared to abortion facilities nationwide and (2) to understand the role of state CPC policy in service access.

STUDY DESIGN

We conducted a national mystery caller study of 445 CPCs and geographically paired abortion facilities, posing as patients seeking pregnancy confirmation. Facility type (CPC vs abortion facility) was the primary exposure in Aim 1. Wait time to first available early pregnancy appointment was the primary outcome. In Aim 2, state-level CPC policy designation (supportive vs not supportive of CPCs) was the primary exposure. Difference in wait time ≥7 days to first available appointment between CPCs and paired abortion facilities was the primary outcome.

RESULTS

CPCs were more likely than abortion facilities to provide same-day appointments (68.5% vs 37.2%, p < 0.0001), and free pregnancy testing (98.0% vs 16.6%, p < 0.0001). The median wait to first available appointment at a CPC was 0 days (IQR 0,1), compared to 1 day at abortion facilities (IQR 0, 5), p < 0.0001. In states with supportive CPC policy environments, abortion facilities were less likely to have wait times exceeding their paired CPC by a week or more, compared to paired facilities in states with non-supportive CPC policy environments (p = 0.033). This remained true after adjusting for state abortion policy environment (p = 0.011).

CONCLUSIONS

Pregnancy confirmation is more accessible at CPCs compared to abortion facilities. Factors other than state-level CPC policies likely influence service accessibility. There is a need for improved access to pregnancy confirmation in medical settings.

IMPLICATIONS

Our findings demonstrating that pregnancy confirmation is more accessible at crisis pregnancy centers than at abortion facilities are predicted to be exacerbated in the wake of abortion clinic closures following the Dobbs v Jackson Women's Health Organization Supreme Court decision. This highlights the need for improved funding and support for pregnancy confirmation service delivery in medical settings, including abortion facilities.

Secret shopper studies: an unorthodox design that measures inequities in healthcare access

Secret shopper studies are particularly potent study designs that allow for the gathering of objective data for a variety of research hypotheses, including but not limited to, healthcare delivery, equity of healthcare, and potential barriers to care. Of particular interest during the COVID-19 pandemic, secret shopper study designs allow for the gathering of data over the phone. However, there is a dearth of literature available on appropriate methodological practices for these types of studies. To make these study designs more widely accessible, here we outline the case for using the secret shopper methodology and detail best practices for designing and implementing them.

Association of Medicaid Expansion With Emergency Department Visits by Medical Urgency

IMPORTANCE

Relatively little is known about the association of the Medicaid eligibility expansion under the Patient Protection and Affordable Care Act with emergency department (ED) visits categorized by medical urgency.

OBJECTIVE

To estimate the association between state Medicaid expansions and ED visits by the urgency of presenting conditions.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study used the Healthcare Cost and Utilization Project State Emergency Department Databases from January 2011 to December 2017 for 2 states that expanded Medicaid in 2014 (New York and Massachusetts) and 2 states that did not (Florida and Georgia). Difference-in-differences regression models were used to estimate the changes in ED visits overall and further stratified by the urgency of the conditions using an updated version of the New York University ED algorithm between the states that expanded Medicaid and those that did not, before and after the expansion. Data were analyzed between June 7 and December 12, 2021.

EXPOSURE

State-level Medicaid eligibility expansion.

MAIN OUTCOMES AND MEASURES

Emergency department visits per 1000 population overall and stratified by medical urgency of the conditions.

RESULTS

In total, 80.6 million ED visits by 26.0 million individuals were analyzed. Emergency department visits were concentrated among women (59.3%), non-Hispanic Black individuals (28.3%), non-Hispanic White individuals (47.8%), and those aged 18 to 34 years (47.5%) and 35 to 44 years (20.4%). The rates of ED visits increased by a mean of 2.4 visits in nonexpansion states and decreased by a mean of 2.2 visits in expansion states after 2014, resulting in a significant regression-adjusted decrease of 4.7 visits per 1000 population (95% CI, -7.7 to -1.5; P = .003) in expansion states. Most of this decrease was associated with decreases in ED visits by conditions classified as not emergent (-1.5 visits; 95% CI, -2.4 to -0.7; P < .001), primary care treatable (-1.1 visits; 95% CI, -1.6 to -0.5; P < .001), and potentially preventable (-0.3 visits; 95% CI, -0.5 to -0.1; P = .02). No significant changes were observed for ED visits related to injuries and conditions classified as not preventable (-1.4; 95% CI, -3.1 to 0.3; P = .10), as well as for substance use and mental health disorders (0.0; 95% CI, -0.2 to 0.2; P = .94).

CONCLUSIONS AND RELEVANCE

The findings of this study suggest that Medicaid expansion was associated with decreases in ED visits, for which decreases in ED visits for less medically emergent ED conditions may have been a factor.

Title: advancing urban health equity in the United States in an age of health care gentrification: a framework and research agenda

Background

Access to health care has traditionally been conceptualized as a function of patient socio-demographic characteristics (i.e., age, race/ethnicity, education, health insurance status, etc.) and/or the system itself (i.e., payment structures, facility locations, etc.). However, these frameworks typically do not take into account the broader, dynamic context in which individuals live and in which health care systems function.

Purpose

The growth in market-driven health care in the U.S. alongside policies aimed at improving health care delivery and quality have spurred health system mergers and consolidations, a shift toward outpatient care, an increase in for-profit care, and the closure of less profitable facilities. These shifts in the type, location and delivery of health care services may provide increased access for some urban residents while excluding others, a phenomenon we term “health care gentrification.“ In this commentary, we frame access to health care in the United States in the context of neighborhood gentrification and a concurrent process of changes to the health care system itself.

Conclusions

We describe the concept of health care gentrification, and the complex ways in which both neighborhood gentrification and health care gentrification may lead to inequitable access to health care. We then present a framework for understanding health care gentrification as a function of dynamic and multi-level systems, and propose ways to build on existing models of health care access and social determinants of health to more effectively measure and address this phenomenon. Finally, we describe potential strategies applied researchers might investigate that could prevent or remediate the effects of health care gentrification in the United States.

Evaluating network adequacy of oral health services for children on Medicaid in Arizona

Purpose

Inadequate networks can prevent patients from being able to see the providers that they trust and depend upon, especially for children insured through Medicaid. To improve our understanding of poor oral health care outcomes, we conducted a test of network adequacy among Medicaid pediatric dental providers in Arizona through a “secret shopper” phone survey.

Methods

This study tested multiple components of children's access to oral health care, including reliability of provider directory information, appointment availability at the practice level for children covered under Medicaid versus commercial insurance, and compliance with regulatory standards. We contacted individual providers, following a standardized script to schedule a routine appointment on behalf of a 5-year-old patient enrolled in either a Medicaid or commercial plan. We documented the time until the next available appointment, if the practice was reached, and if the practice accepted the specified insurance plan.

Results

We identified, catalogued, and attempted to call a total of 185 unique practices across Arizona. In four counties, we were unable to identify a single pediatric oral health provider through health plan directories. We observed minimal differences in appointment wait times between callers with commercial insurance and those insured through Medicaid.

Conclusions

Our findings underscore the need to improve the accessibility of pediatric health services, especially in rural regions. Facilitating access to routine and recommended oral health screenings for children enrolled in Medicaid is imperative to appropriate stewardship and fulfilling our commitment to provide this vital public health resource.

Treatment access for opioid use disorder in pregnancy among rural and American Indian communities

BACKGROUND

Opioid use disorder (OUD) in pregnancy disproportionately impacts rural and American Indian (AI) communities. With limited data available about access to care for these populations, this study's objective was to assess clinic knowledge and new patient access for OUD treatment in three rural U.S. counties.

MATERIAL AND METHODS

The research team used unannounced standardized patients (USPs) to request new patient appointments by phone for white and AI pregnant individuals with OUD at primary care and OB/GYN clinics that provide prenatal care in three rural Utah counties. We assessed a) clinic familiarity with buprenorphine for OUD; b) appointment availability for buprenorphine treatment; c) appointment wait times; d) referral provision when care was unavailable; and e) availability of OUD care at referral locations. We compared outcomes for AI and white USP profiles using descriptive statistics.

RESULTS

The USPs made 34 calls to 17 clinics, including 4 with publicly listed buprenorphine prescribers on the Substance Abuse and Mental Health Services Administration website. Among clinical staff answering calls, 16 (47%) were unfamiliar with buprenorphine. OUD treatment was offered when requested in 6 calls (17.6%), with a median appointment wait time of 2.5 days (IQR 1-5). Among clinics with a listed buprenorphine prescriber, 2 of 4 (50%) offered OUD treatment. Most clinics (n = 24/28, 85.7%) not offering OUD treatment provided a referral; however, a buprenorphine provider was unavailable/unreachable 67% of the time. The study observed no differences in appointment availability between AI and white individuals.

CONCLUSIONS

Rural-dwelling AI and white pregnant individuals with OUD experience significant barriers to accessing care. Improving OUD knowledge and referral practices among rural clinics may increase access to care for this high-risk population.

Impacts of Early ACA Medicaid Expansions on Physician Participation

OBJECTIVE

To quantify impacts of early Affordable Care Act (ACA) Medicaid expansions on Medicaid participation for primary care physicians.

DATA SOURCES

The study uses secondary Medicaid Analytic eXtract (MAX) data from the United States for 2009-2012 as well as secondary National Plan and Provider Enumeration System (NPPES) data from the United States for 2015.

STUDY DESIGN

The study uses a quasi-experimental difference-in-differences study design where the policy change is Medicaid expansion in 6 states that adopted early ACA Medicaid expansions during 2010 and 2011: California, Connecticut, the District of Columbia, Minnesota, New Jersey, and Washington. The key outcome variables are five monthly measures of physician participation: the number of Medicaid visits, the number of Medicaid patients, seeing at least 1 Medicaid patient, seeing at least 25 Medicaid patients, and seeing at least 50 Medicaid patients.

DATA COLLECTION/EXTRACTION METHODS

The sample consists of all physicians who were active between 2005 and 2015 according to the NPPES.

PRINCIPAL FINDINGS

For primary care physicians, Medicaid expansion led to a 29% increase in Medicaid visits (5.88 per month; 95% CI: 2.49 to 9.27), a 29% increase in Medicaid patients (4.59 per month; 95% CI: 2.16 to 7.02), and did not affect the probability of any Medicaid participation. Medicaid expansion also led to a 22% increase in the probability of seeing at least 25 Medicaid patients per month (4.58 percentage points; 95% CI: 1.27 to 7.89) and a 31% increase in the probability of seeing at least 50 Medicaid patients per month (2.99 percentage points; 95% CI: 0.99 to 4.99).

CONCLUSIONS

Early ACA Medicaid expansions led to increased Medicaid visits for primary care physicians but did not affect the probability of any Medicaid participation. Primary care physicians who had previously served Medicaid patients responded to early ACA Medicaid expansions by serving substantially more Medicaid patients.

Primary Care Access During the COVID-19 Pandemic: a Simulated Patient Study

BACKGROUND

Primary care practices have experienced major strains during the COVID-19 pandemic, such that patients newly seeking care may face potential barriers to timely visits.

OBJECTIVE

To quantify availability and wait times for new patient appointments in primary care and to describe how primary care practices are guiding patients with suspected COVID-19.

DESIGN

Trained callers conducted simulated patient calls to 800 randomly sampled primary care practices between September 14, 2020, and September 28, 2020.

PARTICIPANTS

We extracted complete primary care physician listings from large commercial insurance networks in four geographically dispersed states between September 10 and 14, 2020 (n=11,521). After excluding non-physician providers and removing duplicate phone numbers, we identified 2705 unique primary care physician practices from which we randomly sampled 200 practices in each region.

MAIN MEASURES

Primary care appointment availability, median wait time in days, and practice guidance to patients suspecting COVID-19 infection.

KEY RESULTS

Among 56% of listed practices that had accurate contact information listed in the directory, 84% offered a new patient in-person or virtual appointment. Median wait time was 10 days (IQR 3-26 days). The most common guidance in case of suspected COVID-19 was clinician consultation, which was offered in 41% of completed calls. Callers were otherwise directed to on-site testing (14%), off-site testing (24%), a COVID-19 hotline (8%), or an urgent care/emergency department (12%), while 2% of practices had no guidance to offer.

CONCLUSIONS

Despite resource constraints, most reachable primary care practices offered timely new patient appointments as well as direct COVID-19 care. Pandemic mitigation strategies should account for and support the central role of primary care practices in the community-based pandemic response.

The effect of Medicaid expansion on Medicaid participation, payer mix, and labor supply in primary care

Evidence of increased health care utilization associated with the Medicaid expansion suggests that clinicians increased capacity to meet demand. However, little is known about the mechanism underlying this response. Using a novel source of all-payer data, we quantified clinicians' response to the Medicaid expansion - examining whether and how they changed their Medicaid participation decisions, payer mix, and overall labor supply. Primary care clinicians in expansion states provided an average of 49 additional appointments per year (a 21% relative increase) for patients insured by Medicaid, compared to clinicians in non-expansion states - with new-patient visits representing half (25 appointments) of this overall increase. Clinicians did not increase their labor supply to accommodate these additional appointments. They instead offset the 1.7 percentage point average increase in Medicaid payer mix with an equivalent reduction in commercial payer mix. However, this reduction in commercial patient share represented only a 2.8% relative decrease, with commercially insured patients still comprising the majority of the average clinician's patient panel. Subsample analyses revealed a larger increase in care for Medicaid patients among clinicians with high Medicaid participation preceding the eligibility expansion.

Development of an unannounced standardized patient protocol to evaluate opioid use disorder treatment in pregnancy for American Indian and rural communities

BACKGROUND

Opioid use disorder (OUD) disproportionately impacts rural and American Indian communities and has quadrupled among pregnant individuals nationwide in the past two decades. Yet, limited data are available about access and quality of care available to pregnant individuals in rural areas, particularly among American Indians (AIs). Unannounced standardized patients (USPs), or "secret shoppers" with standardized characteristics, have been used to assess healthcare access and quality when outcomes cannot be measured by conventional methods or when differences may exist between actual versus reported care. While the USP approach has shown benefit in evaluating primary care and select specialties, its use to date for OUD and pregnancy is very limited.

METHODS

We used literature review, current practice guidelines for perinatal OUD management, and stakeholder engagement to design a novel USP protocol to assess healthcare access and quality for OUD in pregnancy. We developed two USP profiles-one white and one AI-to reflect our target study area consisting of three rural, predominantly white and AI US counties. We partnered with a local community health center network providing care to a large AI population to define six priority outcomes for evaluation: (1) OUD treatment knowledge among clinical staff answering telephones; (2) primary care clinic facilitation and provision of prenatal care and buprenorphine treatment; (3) appropriate completion of evidence-based screening, symptom assessment, and initial steps in management; (4) appropriate completion of risk factor screening/probing about individual circumstances that may affect care; (5) patient-directed tone, stigma, and professionalism by clinic staff; and (6) disparities in care between whites and American Indians.

DISCUSSION

The development of this USP protocol tailored to a specific environment and high-risk patient population establishes an innovative approach to evaluate healthcare access and quality for pregnant individuals with OUD. It is intended to serve as a roadmap for our own study and for future related work within the context of substance use disorders and pregnancy.

Reproductive-Age Women's Experience of Accessing Treatment for Opioid Use Disorder: "We Don't Do That Here"

PURPOSE

For reproductive-age women, medications for opioid use disorder (OUD) decrease risk of overdose death and improve outcomes but are underutilized. Our objective was to provide a qualitative description of reproductive-age women's experiences of seeking an appointment for medications for OUD.

METHODS

Trained female callers placed telephone calls to a representative sample of publicly listed opioid treatment clinics and buprenorphine providers in Florida, Kentucky, Massachusetts, Michigan, Missouri, North Carolina, Tennessee, Virginia, Washington, and West Virginia to obtain appointments to receive medication for OUD. Callers were randomly assigned to be pregnant or non-pregnant and have private or Medicaid-based insurance to assess differences in the experiences of access by these characteristics. The callers placed 28,651 uniquely randomized calls, 10,117 to buprenorphine-waivered prescribers and 754 to opioid treatment programs. Open-ended, qualitative data were obtained from the callers about the access experiences and were analyzed using a qualitative, iterative inductive-deductive approach. From all 28,651 total calls, there were 17,970 unique free-text comments to the question "Please give an objective play-by-play of the description of what happened in this conversation."

FINDINGS

Analysis demonstrated a common path to obtaining an appointment. Callers frequently experienced long hold times, multiple transfers, and difficult interactions. Clinic receptionists were often mentioned as facilitating or obstructing access. Pregnant callers and those with Medicaid noted more barriers. Obtaining an appointment was commonly difficult even for these persistent, trained callers.

CONCLUSIONS

Interventions are needed to improve the experiences of reproductive-age women as they enter care for OUD, especially for pregnant women and those with Medicaid coverage.

Avoiding Medicaid: Characteristics Of Primary Care Practices With No Medicaid Revenue

Primary care access for Medicaid patients is an ongoing area of concern. Most studies of providers' participation in Medicaid have focused on factors associated with the Medicaid program, such as reimbursement rates. Few studies have examined the characteristics of primary care practices associated with Medicaid participation. We used a nationally representative survey of primary care practices to compare practices with no, low, and high Medicaid revenue. Seventeen percent of practices received no Medicaid revenue; 38 percent and 45 percent were categorized as receiving low and high Medicaid revenue, respectively. Practices with no Medicaid revenue were more often small, independent, and located in urban areas with higher household income. These practices also have lower population health capabilities.

COVID-19: Social Work's Opportunity to Revitalize Advocacy for a Universal, Single-Payer Healthcare System

The COVID-19 pandemic is exposing failures of the for-profit health insurance system in the USA. This social commentary briefly reviews short-term policies that have been enacted to address immediate health insurance needs during the pandemic as well as long-term policies that have been implemented and proposed to solve the shortcomings of this system. Prior to the Patient Protection and Affordable Care Act of 2010, the National Association of Social Workers advocated for a single-payer health care system. The author argues that the COVID-19 pandemic is a watershed moment offering social work an ideal opportunity to revitalize its advocacy and commitment to a single-payer health care system grounded in the Universal Declaration of Human Rights, which asserts that health care is a human right.

The Association Between Hospital Characteristics and Emergency Medical Treatment and Labor Act Citation Events

OBJECTIVES

The Emergency Medical Treatment and Labor Act (EMTALA) is a federal law enacted in 1986 prohibiting patient dumping (refusing or transferring patients with emergency medical conditions without appropriate stabilization), and discrimination based upon ability to pay. We evaluate hospital-level features associated with citation for EMTALA violation.

MATERIALS AND METHODS

A retrospective analysis of observational data on EMTALA enforcement (2005-2013). Regression analysis evaluates the association between facility-level features and odds of EMTALA citation by hospital-year.

RESULTS

Among 4916 EMTALA-obligated hospitals there were 1925 EMTALA citation events at 1413 facilities between 2005 and 2013, with 4.3% of hospitals cited per year. In adjusted analyses, increased odds of EMTALA citations were found at hospitals that were: for-profit [odds ratio (OR): 1.61; 95% confidence interval (CI): 1.32-1.96], in metropolitan areas (OR: 1.32; 95% CI: 1.11-1.57); that admitted a higher proportion of Medicaid patients (OR: 1.01; 95% CI: 1.0-1.01); and were in the top quartiles of hospital size (OR: 1.48; 95% CI: 1.10-1.99) and emergency department (ED) volume (OR: 1.56; 95% CI: 1.14-2.12). Predicted probability of repeat EMTALA citation in the year following initial citation was 17% among for-profit and 11% among other hospital types. Among citation events for patients presenting to the same hospital's ED, there were 1.30 EMTALA citation events per million ED visits, with 1.04 at private not-for-profit, 1.47 at government-owned, and 2.46 at for-profit hospitals.

CONCLUSIONS

For-profit ownership is associated with increased odds of EMTALA citations after adjusting for other characteristics. Efforts to improve EMTALA might be considered to protect access to emergency care for vulnerable populations, particularly at large, urban, for-profit hospitals admitting high proportions of Medicaid patients.

Association of Pregnancy and Insurance Status With Treatment Access for Opioid Use Disorder

IMPORTANCE

Medications for opioid use disorder, including buprenorphine hydrochloride and methadone hydrochloride, are highly effective at improving outcomes for individuals with the disorder. For pregnant women, use of these medications also improves pregnancy outcomes, including the risk of preterm birth. Despite the known benefits of medications for opioid use disorder, many pregnant and nonpregnant women with the disorder are not receiving them.

OBJECTIVE

To determine whether pregnancy and insurance status are associated with a woman's ability to obtain an appointment with an opioid use disorder treatment clinician.

DESIGN, SETTING, AND PARTICIPANTS

In this cross-sectional study with random assignment of clinicians and simulated-patient callers (performed in "secret shopper" format), outpatient clinics that provide buprenorphine and methadone were randomly selected from publicly available treatment lists in 10 US states (selected for variability in opioid-related outcomes and policies) from March 7 to September 5, 2019. Pregnant vs nonpregnant woman and private vs public insurance assigned randomly to callers to create unique patient profiles. Simulated patients called the clinics posing as pregnant or nonpregnant women to obtain an initial appointment with a clinician.

MAIN OUTCOMES AND MEASURES

Appointment scheduling, wait time, and out-of-pocket costs.

RESULTS

A total of 10 871 unique patient profiles were assigned to 6324 clinicians. Among all women, 2312 of 3420 (67.6%) received an appointment with a clinician who prescribed buprenorphine, with lower rates among pregnant vs nonpregnant callers (1055 of 1718 [61.4%] vs 1257 of 1702 [73.9%]; relative risk, 0.83; 95% CI, 0.79-0.87). For clinicians who prescribed methadone, there was no difference in appointment access for pregnant vs nonpregnant callers (240 of 271 [88.6%] vs 237 of 265 [89.4%]; relative risk, 0.99; 95% CI, 0.93-1.05). Insurance was frequently not accepted, with 894 of 3420 buprenorphine-waivered prescribers (26.1%) and 174 of 536 opioid treatment programs (32.5%) granting appointments only when patients agreed to pay cash. Median wait times did not differ between pregnant and nonpregnant callers among buprenorphine prescribers (3 days [interquartile range, 1-7 days] vs 3 days [interquartile range, 1-7 days]; P = .43) but did differ among methadone prescribers (1 day [interquartile range, 1-4 days] vs 2 days [interquartile range, 1-6 days]; P = .049). For patients agreeing to pay cash, the median out-of-pocket costs for initial appointments were $250 (interquartile range, $155-$300) at buprenorphine prescribers and $34 (interquartile range, $15-$120) at methadone prescribers.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study with random assignment of clinicians and simulated-patient callers, many women, especially pregnant women, faced barriers to accessing treatment. Given the high out-of-pocket costs and lack of acceptance of insurance among many clinicians, access to affordable opioid use disorder treatment is a significant concern.

Medicaid Expansion Reduced Emergency Department Visits by Low-income Adults Due to Barriers to Outpatient Care

BACKGROUND

Prior studies have found conflicting effects of Medicaid expansion on emergency department (ED) utilization but have not studied the reasons patients go to EDs.

OBJECTIVES

Examine the changes in reasons for ED use associated with Medicaid expansion.

RESEARCH DESIGN

Difference-in-difference analysis.

SUBJECTS

We included sample adults from the 2012 to 2017 National Health Interview Survey who were US citizens and reported a total family income below 138% federal poverty level (n=30,259).

MEASURES

We examined changes in the proportion of study subjects reporting: (1) any ED visits; (2) ED visits due to perceived illness severity; (3) office not open; and (4) barriers to outpatient care, comparing expansion and nonexpansion states.

RESULTS

Overall, 30.6% of low-income adults reported ED use in the past year, of which 74.1% reported illness acuity, 12.4% reported office not open, 9.5% reported access barriers, and 4.0% did not report any reason. Medicaid expansion was not associated with statistically significant changes in overall ED use [-2.2% (95% confidence interval-CI), -5.5% to 1.2%), P=0.21], ED visits due to perceived illness severity [0.5% (95% CI, -2.4% to 3.5%), P=0.73], or office not open [-0.9% (95% CI, -2.3% to 0.5%); P=0.22], but was associated with significant decrease in ED visits due to access barriers [-1.4% (95% CI, -2.6% to -0.2%), P=0.022].

CONCLUSIONS

Medicaid expansion was associated with a decrease in low-income adults who reported outpatient care barriers as reasons for ED visits. There were no significant changes in overall ED utilization, likely because the majority of respondent reported ED use due to concerns with illness severity or outpatient office was closed.

Medicaid Expansion and Mechanical Ventilation in Asthma, Chronic Obstructive Pulmonary Disease, and Heart Failure

Rationale: The Affordable Care Act's Medicaid expansion has led to increased access to chronic disease care among newly insured adults. Despite this, its effects on clinical outcomes, particularly for patients with asthma, chronic obstructive pulmonary disease, and heart failure, are uncertain. Objectives: To assess whether Medicaid expansion was associated with changes in mechanical ventilation rates among hospitalized patients with heart failure, asthma, and chronic obstructive pulmonary disease. Methods: Difference-in-differences analysis comparing discharge data from four states that expanded Medicaid in 2014 (Arizona, Iowa, New Jersey, and Washington) and three comparison states that did not (North Carolina, Nebraska, and Wisconsin) was performed. Models were adjusted for patient and hospital factors. Results: Mechanical ventilation rates at baseline were 7.2% in nonexpansion states and 8.8% in expansion states. Medicaid expansion was associated with a decline in mechanical ventilation rates at -0.2% per quarter (95% confidence interval [CI], -0.3% to 0.0%; P = 0.010). We did not observe a change in the rate of ICU admission (-0.4% per quarter; 95% CI, -0.8% to 0.1%; P = 0.10) or in-hospital mortality (0.1% per quarter; 95% CI, 0.0% to 0.1%; P = 0.30). In a negative control among adults aged 65 years or older, changes in mechanical ventilation rates were similar, though the CIs crossed zero (-0.1%; 95% CI, -0.2% to 0.0%; P = 0.08). Conclusions: Medicaid expansion may have been associated with a decline in mechanical ventilation rates among uninsured and Medicaid-covered patients admitted with heart failure, chronic obstructive pulmonary disease, and asthma.

Primary Care Access to New Patient Appointments for California Medicaid Enrollees: A Simulated Patient Study

PURPOSE

We undertook a study to evaluate variation in the availability of primary care new patient appointments for Medi-Cal (California Medicaid) enrollees in Northern California, and its relationship to emergency department (ED) use after Medicaid expansion.

METHODS

We placed simulated calls by purported Medi-Cal enrollees to 581 primary care clinicians (PCCs) listed as accepting new patients in online directories of Medi-Cal managed care plans. Data from the California Health Interview Survey, Medi-Cal enrollment reports, and California hospital discharge records were used in analyses. We developed multilevel, mixed-effect models to evaluate variation in appointment access. Multiple linear regression was used to examine the relationship between primary care access and ED use by county.

RESULTS

Availability of PCC new patient appointments to Medi-Cal enrollees lacking a PCC varied significantly across counties in the multilevel model, ranging from 77 enrollees (95% CI, 70-81) to 472 enrollees (95% CI, 378-628) per each available new patient appointment. Just 19% of PCCs had available appointments within the state-mandated 10 business days. Clinicians at Federally Qualified Health Centers had higher availability of new patient appointments (rate ratio = 1.56; 95% CI, 1.24-1.97). Counties with poorer PCC access had higher ED use by Medi-Cal enrollees.

CONCLUSIONS

In contrast to findings from other states, access to primary care in Northern California was limited for new patient Medi-Cal enrollees and varied across counties, despite standard statewide reimbursement rates. Counties with more limited access to primary care new patient appointments had higher ED use by Medi-Cal enrollees.

Association Between the ACA Medicaid Expansions and Primary Care and Emergency Department Use During the First 3 Years

BACKGROUND

Evidence is limited and mixed as to how the Patient Protection and Affordable Care Act (ACA) Medicaid expansions affected the utilization of primary care physicians (PCPs) and emergency departments (EDs) at the national level.

OBJECTIVE

To examine the association between the ACA Medicaid expansions and changes in the utilization of PCP and ED visits at the national level during the first 3 years (2014-2016) of the implementation.

DESIGN

A difference-in-differences analysis to compare outcomes between individuals in 32 states that expanded Medicaid versus individuals in 19 non-expansion states.

PARTICIPANTS

A nationally representative sample of US-born individuals 26-64 years old with family incomes lower than 138% of the federal poverty level from the 2010-2016 Medical Expenditure Panel Survey.

INTERVENTION

ACA Medicaid expansions MAIN MEASURES: We examined PCP-related outcomes ((i) whether a participant had any PCP visit during a year and (ii) the annual number of PCP visits per person) and ED-related outcomes ((i) whether a participant had any ED visit during a year and (ii) the annual number of ED visits per person).

KEY RESULTS

A total of 17,803 participants were included in our analysis. We found that the proportion of individuals with any PCP visit during a year marginally increased (difference-in-differences estimate, + 3.6 percentage points [pp]; 95% CI, - 0.4 pp to + 7.6 pp; P = 0.08) following the Medicaid expansions, without any change in the annual number of PCP visits per person. We found no evidence that ED utilization (both the proportion of individuals with any ED visit during a year and the annual number of ED visits per person) changed meaningfully after the Medicaid expansions.

CONCLUSION

Using the nationally representative data of individuals who were affected by the ACA, we found that the ACA Medicaid expansions were associated with a modest improvement in access to PCPs without an increase in ED use.

Does Primary Care Provider Supply Influence Medicaid Acceptability?

BACKGROUND

Following the Affordable Care Act's Medicaid expansions, access to care improved through elevated coverage rates among the low-income population. In Michigan, a major factor contributing to improved access among low-income patients was increased Medicaid acceptance in primary care settings.

OBJECTIVES

Prior evidence shows substantial geographic variation preacceptance and postacceptance of Medicaid. In this study, we determine whether physician's willingness to accept new Medicaid patients is moderated by the availability of other providers in close proximity.

METHODS

The study uses Michigan simulated patient (ie, "secret shopper") data collected during 2014 and 2015, and applies a difference-in-differences styled event-study regression approach comparing trends in Medicaid acceptability and appointment scheduling between areas in Michigan with higher densities of primary care providers against those with lower densities of providers that could arguably be classified a health professional shortage areas.

RESULTS

Through one year after Michigan's Medicaid expansion, practices in low-supply areas appeared no more likely (P>0.10) to turn away a newly insured Medicaid patient than a practice in a supply-rich area. The wait times for patients in a low-supply area were about a day longer (P<0.05) than for patients in supply-rich areas through 4 months after the expansion, though this difference dissipated through 8 and 12 months after the expansion.

CONCLUSIONS

These results indicate that newly insured Medicaid patients are gaining access to care in settings with limited health care supply.

Association of Medicaid Expansion With Coverage and Access to Care for Pregnant Women

OBJECTIVE

To identify the association of the Affordable Care Act's Medicaid expansion with payment for delivery, early access to prenatal care, preterm birth, and birth weights considered small for gestational age (SGA).

METHODS

A difference-in-difference design was used to assess changes in outcomes before and after Medicaid expansion in expansion states, using nonexpansion states as a control group. We used national birth certificate data from 2009 to 2017. Difference-in-difference linear probability models were used to assess the effects of the policy implementation, adjusting for demographics, month of birth, state, year, and county-level unemployment rates. Standard errors were clustered at the state level. Two prespecified subgroup analyses were performed of nulliparous women and women with no more than a high school diploma.

RESULTS

The study sample included 8,701,889 women from 15 expansion states and 9,509,994 from 11 nonexpansion states. In the adjusted analysis, the percentage of Medicaid-covered deliveries increased by 2.3 absolute percentage points (95% CI 0.2-4.4, P=.04) in expansion states compared with nonexpansion states. There were no significant changes in the proportion of women who were uninsured, as there was a relative decrease in the percentage of deliveries covered by private insurance (-2.8 percentage points [95% CI -4.9 to -0.8, P=.01]). There were also no significant differences in the rate of women initiating prenatal care in the first trimester, preterm birth rates, or rates of low birth weight after the Medicaid expansion. Findings were similar in both subgroups.

CONCLUSION

Medicaid expansion was associated with increased Medicaid coverage for childbirth in expansion states; similar gains in private coverage were seen in nonexpansion states. There were no associations with changes in early access to prenatal care, preterm birth, or SGA birth weights.

Access to Primary Care Clinics for Patients With Chronic Pain Receiving Opioids

IMPORTANCE

Opioid-prescribing policies and guidelines aimed at reducing inappropriate opioid prescribing may lead physicians to stop prescribing opioids. Patients may thus encounter difficulties finding primary care practitioners willing to care for them if they take opioids.

OBJECTIVES

To assess practitioner willingness to accept and continue prescribing opioids to new patients with pain and whether this willingness differs across payer types.

DESIGN, SETTING, AND PARTICIPANTS

This survey study used a simulated patient call audit method. A brief telephone survey was administered to all clinics followed by a call using a patient script simulating an adult patient with chronic pain who was taking long-term opioids. The patient had Medicaid or private insurance. Calls were made between June 22 and October 30, 2018, to 667 primary care clinics that served a general adult population in Michigan. Clinics that accepted both Medicaid and private insurance, took new patient appointments, and were successfully recontacted for the simulated call were eligible for the study.

MAIN OUTCOMES AND MEASURES

Prevalence of clinics' acceptance of new patients receiving prescription opioids overall and by clinic characteristics and insurance type.

RESULTS

Of the 194 eligible clinics, 94 (48.4%) were randomized according to insurance type to receive calls from research assistants posing as children of patients with Medicaid and 100 (51.5%) to receive calls from those with private insurance. Overall, 79 (40.7%) stated that their practitioners would not prescribe opioids to the simulated patient. Thirty-three clinics (17.0%) requested more information before making a decision. Compared with single-practitioner clinics, clinics with more than 3 practitioners were more likely (odds ratio [OR], 2.99; 95% CI, 1.48-6.04) to accept new patients currently taking opioids. No difference was found in access based on insurance status (OR, 0.92; 95% CI, 0.52-1.64) or whether the clinic offered medications for opioid use disorders (OR, 1.10; 95% CI, 0.45-2.69).

CONCLUSIONS AND RELEVANCE

The findings suggest that access to primary care may be reduced for patients taking prescription opioids, which could lead to unintended consequences, such as conversion to illicit substances or reduced management of other medical comorbidities.

Access to Office-Based Buprenorphine Treatment in Areas With High Rates of Opioid-Related Mortality: An Audit Study

BACKGROUND

Improving access to treatment for opioid use disorder is a national priority, but little is known about the barriers encountered by patients seeking buprenorphine-naloxone ("buprenorphine") treatment.

OBJECTIVE

To assess real-world access to buprenorphine treatment for uninsured or Medicaid-covered patients reporting current heroin use.

DESIGN

Audit survey ("secret shopper" study).

SETTING

6 U.S. jurisdictions with a high burden of opioid-related mortality (Massachusetts, Maryland, New Hampshire, West Virginia, Ohio, and the District of Columbia).

PARTICIPANTS

From July to November 2018, callers contacted 546 publicly listed buprenorphine prescribers twice, posing as uninsured or Medicaid-covered patients seeking buprenorphine treatment.

MEASUREMENTS

Rates of new appointments offered, whether buprenorphine prescription was possible at the first visit, and wait times.

RESULTS

Among 1092 contacts with 546 clinicians, schedulers were reached for 849 calls (78% response rate). Clinicians offered new appointments to 54% of Medicaid contacts and 62% of uninsured-self-pay contacts, whereas 27% of Medicaid and 41% of uninsured-self-pay contacts were offered an appointment with the possibility of buprenorphine prescription at the first visit. The median wait time to the first appointment was 6 days (interquartile range [IQR], 2 to 10 days) for Medicaid contacts and 5 days (IQR, 1 to 9 days) for uninsured-self-pay contacts. These wait times were similar regardless of clinician type or payer status. The median wait time from first contact to possible buprenorphine induction was 8 days (IQR, 4 to 15 days) for Medicaid and 7 days (IQR, 3 to 14 days) for uninsured-self-pay contacts.

LIMITATION

The survey sample included only publicly listed buprenorphine prescribers.

CONCLUSION

Many buprenorphine prescribers did not offer new appointments or rapid buprenorphine access to callers reporting active heroin use, particularly those with Medicaid coverage. Nevertheless, wait times were not long, implying that opportunities may exist to increase access by using the existing prescriber workforce.

Primary Care Clinicians' Views About the Impact of Medicaid Expansion in Michigan: A Mixed Methods Study

BACKGROUND

Michigan's approach to Medicaid expansion, the Healthy Michigan Plan (HMP), emphasizes primary care, prevention, and incentives for patients and primary care practitioners (PCPs).

OBJECTIVE

Assess PCPs' perspectives about the impact of HMP on their patients and practices.

DESIGN

In 2014-2015, we conducted semi-structured interviews then a statewide survey of PCPs.

SETTING

Interviewees came from varied types of practices in five Michigan regions selected for racial/ethnic diversity and a mix of rural and urban settings. Surveys were sent via mail.

PARTICIPANTS

Interviewees were physician (n = 16) and non-physician practitioners (n = 3). All Michigan PCPs caring for ≥ 12 HMP enrollees were surveyed (response rate 55.5%, N = 2104).

MEASUREMENTS

PCPs' experiences with HMP patients and recent changes in their practices.

RESULTS

Interviews include examples of the impact of Medicaid expansion on patients and practices. A majority of surveyed PCPs reported recent increases in new patients (52.3%) and patients who had not seen a PCP in many years (56.2%). For previously uninsured patients, PCPs reported positive impact on control of chronic conditions (74.4%), early detection of serious illness (71.1%), medication adherence (69.1%), health behaviors (56.5%), emotional well-being (57.0%), and the ability to work, attend school, or live independently (41.5%). HMP patients reportedly still had more difficulty than privately insured patients accessing some services. Most PCPs reported that their practices had, in the past year, hired clinicians (53.2%) and/or staff (57.5%); 15.4% had colocated mental health care. Few (15.8%) reported established patients' access to urgent appointments worsened.

LIMITATIONS

PCP reports of patient experiences may not be accurate. Results reflect the experiences of PCPs with ≥ 12 Medicaid patients. Differences between respondents and non-respondents present the possibility for response bias.

CONCLUSIONS

PCPs reported improved patient access to care, medication adherence, chronic condition management, and detection of serious illness. Established patients' access did not diminish, perhaps due to reported practice changes.

Health care in a multi-payer system: Spillovers of health care service demand among adults under 65 on utilization and outcomes in medicare

This paper examines, theoretically and empirically, how changes in the demand for health insurance and medical services in the non-Medicare population - coverage eligibility changes for parents and the firm size composition of employment - spill over and affect health insurance coverage and how these factors affect per beneficiary Medicare spending. We find that factors that increase coverage and hence demand for medical services in the non-Medicare population generate contemporaneous decreases in per beneficiary Medicare spending and utilization, particularly for high variation services. Moreover, these increases in the demand for medical services in the non-Medicare population are not associated with increases in the total quantity of physician services supplied. Finally, we find that the higher Medicare spending associated with lower insurance coverage rates in the non-Medicare population does not generate improvements in measures of Medicare patients' well-being, such as patient experience of care, ambulatory-care sensitive admissions, and mortality.

Outpatient Office Wait Times And Quality Of Care For Medicaid Patients

The time patients spend in a doctor's waiting room prior to a scheduled appointment is an important component of the quality of the overall health care experience. We analyzed data on twenty-one million outpatient visits obtained from electronic health record systems, which allowed us to measure time spent in the waiting room beyond the scheduled appointment time. Median wait time was a little more than four minutes. Almost one-fifth of visits had waits longer than twenty minutes, and 10 percent were more than thirty minutes. Waits were shorter for early-morning appointments, for younger patients, and at larger practices. Median wait time was 4.1 minutes for privately insured patients and 4.6 minutes for Medicaid patients. After adjustment for patient and appointment characteristics, Medicaid patients were 20 percent more likely than the privately insured patients to wait longer than twenty minutes, with most of this disparity explained by differences in practices and providers they saw. Wait times for Medicaid patients relative to privately insured patients were longer in states with relatively lower Medicaid reimbursement rates. The study complements other work that suggests that Medicaid patients face some additional barriers in the receipt of care.

Geographic Variation in Medicaid Acceptance Across Michigan Primary Care Practices in the Era of the Affordable Care Act

Coverage and access have improved under the Affordable Care Act, yet it is unclear whether recent gains have reached those regions within states that were most in need of improved access to care. We examined geographic variation in Medicaid acceptance among Michigan primary care practices before and after Medicaid expansion in the state, using data from a simulated patient study of primary care practices. We used logistic regression analysis with time indicators to assess regional changes in Medicaid acceptance over time. Geographic regions with lower baseline (<50%) Medicaid acceptance had significant increases in Medicaid acceptance at 4 and 8 months post-expansion, while regions with higher baseline (≥50%) Medicaid acceptance did not experience significant changes in Medicaid acceptance. As state Medicaid expansions continue to be implemented across the country, policy makers should consider the local dynamics of incentives for provider participation in Medicaid.

Patient-Perceived Access to Care When Actively Seeking Treatment

PURPOSE/OBJECTIVES

To examine predictors of perceived access to care and reported barriers to care of patients with cancer actively seeking treatment.
.

DESIGN

Retrospective secondary data analysis.
.

SETTING

U.S. Medical Expenditure Panel Survey, a national survey with questions about healthcare coverage and access.
.

SAMPLE

1,170 adults with cancer actively seeking treatment.
.

METHODS

A retrospective analysis of data. Bivariate tests for significant association between individual characteristics and low perceived access to care were conducted using a chi-square test. 
.

MAIN RESEARCH VARIABLES

The dependent variable was perceived access to care. The independent variables included sex, age, race, poverty status, education level, marital status, cancer site, comorbidities, and insurance status.
.

FINDINGS

Those with Medicaid insurance or no health insurance had significantly lower perceived access to care compared to those with Medicare. Institutional barriers to treatment, such as financial or insurance, were the most common reported barriers.
.

CONCLUSIONS

Most adults with cancer reported adequate access to medical care and medications, but a small yet vulnerable population expressed difficulties in accessing treatment.
.

IMPLICATIONS FOR NURSING

To effectively advocate for vulnerable populations with Medicaid or no insurance, nurses may require specialized knowledge beyond the scope of general oncology nursing.

Access to Primary Care Appointments Following 2014 Insurance Expansions

PURPOSE

The Patient Protection and Affordable Care Act (ACA) expanded coverage to roughly 12 million individuals by mid-2014 and 20 million by 2016, raising concern about the capacity of the primary care system to absorb these individuals. We set out to determine how justified the concern was.

METHODS

We used an audit design in which simulated patients called primary care practices seeking new-patient appointments in 10 diverse states (Arkansas, Georgia, Iowa, Illinois, Massachusetts, Montana, New Jersey, Oregon, Pennsylvania, and Texas) from November 2012 through March 2013 and from May 2014 through July 2014, before and after the major ACA insurance expansions. Callers were randomly assigned to scripts specifying either private or Medicaid insurance and called only offices identified as "in network" for each plan.

RESULTS

We completed 5,385 private insurance and 4,352 Medicaid calls in 2012-2013 and 2,424 private insurance and 2,474 Medicaid calls in 2014. Overall appointment rates for private insurance remained stable from 2012 (84.7%) to 2014 (85.8%) with Massachusetts and Pennsylvania experiencing significant increases. Overall, Medicaid appointment rates increased 9.7 percentage points (57.9% to 67.6%) with substantial variation by state. Across all callers, median wait times for those obtaining an appointment were 7 days in 2012 and 5 days in 2014, but the difference was not statistically significant.

CONCLUSIONS

Contrary to widespread concern, we find no evidence that the millions of individuals newly insured through the ACA decreased new-patient appointment availability across 10 states as shown by stable wait times and appointment rates for private insurance as of mid-2014.

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.

New Medicaid Enrollees See Health and Social Benefits in Pennsylvania's Expansion

Understanding how new Medicaid enrollees are approaching their own health and health care in the shifting health care landscape of the Affordable Care Act has implications for future outreach and enrollment efforts, as well as service planning for this population. The objective of this study was to explore the health care experiences and expectations of new Medicaid expansion beneficiaries in the immediate post-enrollment period. We conducted semistructured, qualitative interviews with a random sample of 40 adults in Philadelphia who had completed an application for Medicaid through a comprehensive benefits organization after January 1, 2015, when the Medicaid expansion in Pennsylvania took effect. We conducted an inductive, applied thematic analysis of interview transcripts. The new Medicaid beneficiaries described especially high levels of pent-up demand for care. Dental care was a far more pressing and motivating concern than medical care. Preventive services were also frequently mentioned. Participants anticipated that insurance would reduce both stress and financial strain and improve their experience in the health care system by raising their social standing. Participants highly valued the support of telephone application counselors in the Medicaid enrollment process to overcome bureaucratic obstacles they had encountered in the past. Dental care and preventive services appear to be high priorities for new Medicaid enrollees. Telephone outreach and enrollment support services can be an effective way to overcome past experiences with administrative barriers.

The Affordable Care Act and Diabetes Diagnosis and Care: Exploring the Potential Impacts

This article reviews available data on the implications of the Affordable Care Act (ACA) for the diagnosis and care of type 2 diabetes. We provide a general overview of the major issues for diabetes diagnosis and care, and describe the policies in the ACA that affect diabetes diagnosis and care. We also estimate that approximately 2.3 million of the 4.6 million people in the USA with undiagnosed diabetes aged 18-64 in 2009-2010 may have gained access to free preventive care under the ACA, which could increase diabetes detection. In addition, we note two factors that may limit the success of the ACA for improving access to diabetes care. First, many states with the highest diabetes prevalence have not expanded Medicaid eligibility, and second, primary care providers may not adequately meet the increase in Medicaid patients because federal funding to increase provider reimbursement for Medicaid visits recently expired. We close by discussing current gaps in the literature and future directions for research on the ACA's impact on diabetes diagnosis, care, and health outcomes.

Measuring Medicaid Physician Participation Rates and Implications for Policy

Policy makers continue to debate Medicaid expansion under the Affordable Care Act, and concerns remain about low provider participation in the program. However, there has been little research on how various measures of physician participation may reflect different elements of capacity for care within the Medicaid program and how these distinct measures correlate with one another across states. Our objectives were to describe several alternative measures of provider participation in Medicaid using recently publicly available data, to compare state rankings across these different metrics, and to discuss potential advantages and disadvantages of each measure for research and policy purposes. Overall, we find that Medicaid participation as measured by raw percentages of physicians taking new Medicaid patients is only weakly correlated with population-based measures that account for both participation rates and the numbers of physicians per capita or physicians per Medicaid beneficiary. Participation rates for all physicians versus primary care physicians also offer different information about state-level provider capacity. Policy makers should consider multiple dimensions of provider access in assessing policy options in Medicaid, and further research is needed to evaluate the linkages between these provider-based measures and beneficiaries' perceptions of access to care in the program.

Testing the Validity of Primary Care Physicians' Self-Reported Acceptance of New Patients by Insurance Status

OBJECTIVE

To compare physicians' self-reported willingness to provide new patient appointments with the experience of research assistants posing as either a Medicaid beneficiary or privately insured person seeking a new patient appointment.

DATA SOURCES/STUDY SETTING

Survey administered to California physicians and telephone calls placed to a subsample of respondents.

STUDY DESIGN

Cross-sectional comparison.

DATA COLLECTION/EXTRACTION METHODS

All physicians whose California licenses were due for renewal in June or July 2013 were mailed a survey, which included questions about acceptance of new Medicaid and new privately insured patients. Subsequently, research assistants using a script called the practices of a stratified random sample of 209 primary care physician respondents in an attempt to obtain a new patient appointment. By design, half of the physicians selected for the telephone validation reported on the survey that they accepted new Medicaid patients and half indicated that they did not.

PRINCIPAL FINDINGS

The percentage of callers posing as Medicaid patients who could schedule new patient appointments was 18 percentage points lower than the percentage of physicians who self-reported on the survey that they accept new Medicaid patients. Callers were also less likely to obtain appointments when they posed as patients with private insurance.

CONCLUSIONS

Physicians overestimate the extent to which their practices are accepting new patients, regardless of insurance status.
