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

Cross-Sectional Evaluation of State-Level Protections, Medical Debt, and Deferred Care Among Sexual and Gender Minority People

BACKGROUND

Millions of Americans have medical debt and/or defer care due to cost. Few studies have examined the association of such health-related financial problems with sexual orientation or gender identity, and whether state-level policies protecting sexual and gender minority (SGM) people affect disparities in such problems.

OBJECTIVE

To examine the relationships between SGM status, state-level SGM protections, and health-related financial problems.

DESIGN

Cross-sectional analysis.

PARTICIPANTS

Nationally-representative sample of U.S. adults in the 2021 National Financial Capability Study.

MAIN MEASURES

Prevalence of medical debt and/or deferred care; adjusted odds ratios (aORs) by SGM status and residence in a state with fewer SGM protections.

KEY RESULTS

Of 25,170 survey respondents, 3.7% were gay/bisexual men, 4.3% lesbian/bisexual women, and 0.6% transgender people. Among lesbian/bisexual women, 39.4% had medical debt, the highest proportion of any group. Accounting for sociodemographic and personal-financial factors, women and all lesbian/gay/bisexual persons (vs. straight men) more often experienced medical debt (aOR [95% CI]: straight women 1.28 [1.16, 1.41], gay/bisexual men 1.55 [1.23, 1.94], lesbian/bisexual women 1.80 [1.50, 2.10]) or deferred care (e.g., 1.80 [1.51, 2.16] for lesbian/bisexual women). Transgender people vs. cisgender men were more likely to defer care (aOR = 2.58 [1.54, 4.30]). Living in a state with fewer SGM protections was associated with higher rates of health-related financial problems for most groups, especially cisgender women and lesbian/bisexual women.

CONCLUSIONS

Lesbian/gay/bisexual, female, and transgender adults experience more health-related financial problems, especially in states lacking SGM protections, underlining the importance of universal, comprehensive insurance coverage (including for services unique to SGM people), ending bans on gender-affirming care, and closing the male-female pay gap.

A Few Doctors Will See Some of You: The Critical Role of Underrepresented in Medicine (URiM) Family Physicians in the Care of Medicaid Beneficiaries

PURPOSE

Despite being key to better health outcomes for patients from racial and ethnic minority groups, the proportion of underrepresented in medicine (URiM) physicians remains low in the US health care system. This study linked a nationally representative sample of family physicians (FPs) with Medicaid claims data to explore the relative contributions to care of Medicaid populations by FP race and ethnicity.

METHODS

This descriptive cross-sectional study used 2016 Medicaid claims data from the Transformed Medicaid Statistical Information System and from 2016-2017 American Board of Family Medicine certification questionnaire responses to examine the diversity and Medicaid participation of FPs. We explored the diversity of FP Medicaid patient panels and whether they saw ≥150 beneficiaries in 2016. Using logistic regression models, we controlled for FP demographics, practice characteristics, and characteristics of the communities in which they practiced.

RESULTS

Of 13,096 FPs, Latine, Hispanic, or of Spanish Origin (LHS) FPs and non-LHS Black FPs saw more Medicaid beneficiaries compared with non-LHS White and non-LHS Asian FPs. The patient panels of URiM FPs had a much greater proportion of Medicaid beneficiaries from racial and ethnic minority groups. Overall, non-LHS Black and LHS FPs had greater odds of seeing ≥150 Medicaid beneficiaries in 2016.

CONCLUSIONS

These findings clearly show the critical role URiM FPs play in caring for Medicaid beneficiaries, suggesting physician race and ethnicity are correlated with Medicaid participation. Diversity in the health care workforce is essential for addressing racial health inequities. Policies need to address problems in pathways to medical education, including failures to recruit, nurture, and retain URiM students.

Analysis of social determinants of health on emergency department utilization by gunshot wound survivors after level 1 trauma center discharge

Background

This project analyzed risk factors for emergency department (ED) utilization without readmission within 2 weeks post-discharge for survivors of gun violence.

Methods

A hundred gun violence survivors admitted to a Level 1 trauma center were surveyed. Descriptive analyses and group comparisons were conducted between patients who did and did not use the ED. Factors analyzed are rooted in social determinants of health and clinical care related to the index hospitalization.

Results

Of the 100 patients, 31 had an ED visit within 6 weeks, although most (87.1%) returned within 2 weeks of discharge. Factors significantly associated (p≤0.05) with a return ED visit included: not having an identified primary care provider, not having friends or family to count on for help, not having enough money to support themselves before return to work, and not feeling able to read discharge instructions.

Conclusion

Lack of a primary care provider, low health literacy and social support were associated with increased ED visits without readmission post-discharge.

Medicaid Managed Care and Pediatric Dental Emergency Department Visits

Importance

Millions of economically disadvantaged children depend on Medicaid for dental care, with states differing in whether they deliver these benefits using fee-for-service or capitated managed care payment models. However, there is limited research examining the association between managed care and the accessibility of dental services.

Objective

To estimate the association between the adoption of managed care for dental services in Florida's Medicaid program and nontraumatic dental emergency department visits and associated charges.

Design, Setting, and Participants

This cohort study used an event-study difference-in-differences design, leveraging Florida Medicaid's staggered adoption of managed care to examine its association with pediatric nontraumatic dental emergency department visits and associated charges. This study included all Florida emergency department visits from 2010 to 2014 in which the patient was 17 years or younger, the patient was a Florida resident, Medicaid paid for the visit, and a primary or secondary International Classification of Diseases, Ninth Revision, code was used to classify a nontraumatic dental condition. Analyses were conducted between May 2023 and April 2024.

Exposure

The county of residence transitioning Medicaid dental services from fee-for-service to a fully capitated managed care program managed by a dental plan.

Main Outcomes and Measures

The rate of nontraumatic dental emergency department visits per 100 000 pediatric Medicaid enrollees and the associated mean charges per visit. Nontraumatic dental emergency department visits are a well-documented proxy for access to dental care. Data on emergency department visit counts came from the Florida Agency for Health Care Administration. Medicaid population denominators were derived from the American Community Survey's 5-year estimates.

Results

Among the 34 414 pediatric nontraumatic dental emergency department visits that met inclusion criteria across Florida's 67 counties, the mean (SD) age of patients was 8.11 (5.28) years, and 50.8% of patients were male. Of these, 10 087 visits occurred in control counties and 24 327 in treatment counties. Control counties generally had lower rates of NTDC ED visits per 100 000 enrollees compared with treatment counties (123.5 vs 132.7). Over the first 2.5 years of implementation, the adoption of managed care was associated with an 11.3% (95% CI, 4.0%-18.4%; P = .002) increase in nontraumatic dental emergency department visits compared with pre-implementation levels. There was no evidence that the average charge per visit changed.

Conclusions and Relevance

In this cohort study, Florida Medicaid's adoption of managed care for pediatric dental services was associated with increased emergency department visits for children, which could be associated with decreased access to dental care.

Physician selection for hospital integration: Theoretical considerations and empirical findings

BACKGROUND

The U.S. health care system has seen an increase in hospital-physician integration, with hospitals acquiring increasing numbers of physician practices. This shift has been linked to higher costs without significant improvements in quality.

PURPOSE

This study sought to identify the characteristics of physicians who transitioned from independent practice to hospital integration.

METHODOLOGY/APPROACH

We used physician variables, including quality scores, medical school rankings, years of experience, experience treating socially or medically complex patients, practice style, and location, as well as health care market and county-level variables to understand these determinants using a fixed-effects logistic regression model.

RESULTS

A total of 101,746 physicians representing 66 clinical specialties satisfied our inclusion criteria, of which 3,656 became hospital-integrated between 2018 and 2020. The integrating physicians were generally less experienced, had lower quality scores, and generated less revenue per Medicare patient. Their patients, on average, had higher comorbidity scores, were more likely to be dually eligible, and resided in counties with higher poverty rates.

CONCLUSION

Our findings indicate that the physicians most likely to become hospital integrated are those facing reimbursement pressures due to a complex case mix and the associated challenges of performing well on the quality metrics. We also found some support for the anticompetitive aspects of hospital-physician integration. Our results suggest that hospitals are integrating with a relatively less experienced physician workforce but one that is perhaps more capable of treating clinically and socioeconomically complex patients.

PRACTICE IMPLICATIONS

Hospitals interested in using physician integration strategically to improve care quality should put more emphasis on physician quality. Such an approach has the potential to increase efficiency without sacrificing quality of care.

Training in Residency and Provision of Reproductive Health Services Among Family Medicine Physicians

Importance

Contraception and abortion services are essential health care, and family medicine (FM) physicians are an important part of the workforce providing this care. Residency could inform the reproductive health services FM physicians provide.

Objective

To determine which residency training factors are associated with FM physicians' provision of reproductive health services to Medicaid beneficiaries.

Design, Setting, and Participants

This cross-sectional, population-based observational study of inpatient and outpatient FM physicians who completed residency between 2008 and 2018 and treated at least 1 Medicaid beneficiary in 2019 was conducted from November 2022 to March 2023. The study used 2019 American Medical Association Masterfile and Historical Residency file, as well as the 2019 Transformed Medicaid Statistical Information System claims.

Exposures

Residency training in community-based or reproductive health-focused programs.

Main Outcomes and Measures

The outcomes were providing the following to at least 1 Medicaid beneficiary in 2019: prescription contraception (pill, patch, and/or ring), intrauterine device (IUD) and/or contraceptive implant, and dilation and curettage (D&C). Odds of providing each outcome were measured using correlated random-effects regression models adjusted for physician, residency program, and county characteristics.

Results

In the sample of 21 904 FM physician graduates from 410 FM residency programs, 12 307 were female (56.3%). More than half prescribed contraception to Medicaid beneficiaries (13 373 physicians [61.1%]), with lower proportions providing IUD or implant (4059 physicians [18.5%]) and D&C (152 physicians [.7%]). FM physicians who graduated from a Reproductive Health Education in Family Medicine program, which fully integrates family planning into residency training, had significantly greater odds of providing prescription contraception (odds ratio [OR], 1.23; 95% CI, 1.07-1.42), IUD or implant (OR, 1.79; 95% CI, 1.28-2.48), and D&C (OR, 3.61; 95% CI, 2.02-6.44). Physicians who completed residency at a Teaching Health Center, which emphasizes community-based care, had higher odds of providing an IUD or implant (OR, 1.51; 95% CI, 1.19-1.91).

Conclusions and Relevance

In this cross-sectional study of FM physicians providing Medicaid service, characteristics of residency training including community-based care and integration of family planning training are associated with greater odds of providing reproductive health services. With growing reproductive health policy restrictions, providing adequate training in reproductive health is critical to maintaining access to care, especially for underserved populations.

Dentists Who Participate in Medicaid: Who They Are, Where They Locate, How They Practice

Low utilization of dental services among low-income individuals and racial minorities reflects pervasive inequities in U.S. health care. There is limited research determining common characteristics among dentists who participate in Medicaid or the Children's Health Insurance Program. Using detailed Medicaid claims data and a provider database, we estimate that among dentists with 100 or more pediatric Medicaid patients, 48% practice in high-poverty areas, 10% practice in rural areas, and 29% work in large practices (11 or more dentists). Among those with zero Medicaid patients, 18% practice in high-poverty areas, 4% practice in rural areas, and 11% work in large practices. We found that dentist race/ethnicity has an independent effect on Medicaid participation even when adjusting for community characteristics, meaning non-White dentists are more likely to treat Medicaid patients, regardless of the median income or racial/ethnic profile of the community.

Association of Primary Care Physicians' Individual- and Community-Level Characteristics With Contraceptive Service Provision to Medicaid Beneficiaries

Importance

Little is known about primary care physicians who provide contraceptive services to Medicaid beneficiaries. Evaluating this workforce may help explain barriers to accessing these services since contraceptive care access is critical for Medicaid beneficiaries' health.

Objective

To describe the primary care physician workforce that provides contraceptive services to Medicaid beneficiaries and explore the factors associated with their Medicaid contraceptive service provision.

Design, Setting, and Participants

This cross-sectional study, conducted from August 1 to October 10, 2022, used data from the Transformed Medicaid Statistical Information System from 2016 for primary care physicians from 4 specialties (family medicine, internal medicine, obstetrics and gynecology [OBGYN], and pediatrics).

Main Outcomes and Measures

The main outcomes were providing intrauterine devices (IUDs) or contraceptive implants to at least 1 Medicaid beneficiary, prescribing hormonal birth control methods (including a pill, patch, or ring) to at least 1 Medicaid beneficiary, the total number of Medicaid beneficiaries provided IUDs or implants, and the total number Medicaid beneficiaries prescribed hormonal birth control methods in 2016. Physician- and community-level factors associated with contraceptive care provision were assessed using multivariate regression methods.

Results

In the sample of 251 017 physicians (54% male; mean [SD] age, 49.17 [12.58] years), 28% were international medical graduates (IMGs) and 70% practiced in a state that had expanded Medicaid in 2016. Of the total physicians, 48% prescribed hormonal birth control methods while 10% provided IUDs or implants. For OBGYN physicians, compared with physicians younger than 35 years, being aged 35 to 44 years (odds ratio [OR], 3.51; 95% CI, 2.93-4.21), 45 to 54 years (OR, 3.01; 95% CI, 2.43-3.72), or 55 to 64 years (OR, 2.27; 95% CI, 1.82-2.83) was associated with higher odds of providing IUDs and implants. However, among family medicine physicians, age groups associated with lower odds of providing IUDs or implants were 45 to 54 years (OR, 0.66; 95% CI, 0.55-0.80), 55 to 64 years (OR, 0.51; 95% CI, 0.39-0.65), and 65 years or older (OR, 0.29; 95% CI, 0.19-0.44). Except for those specializing in OBGYN, being an IMG was associated with lower odds of providing hormonal contraceptive service (family medicine IMGs: OR, 0.80 [95% CI, 0.73-0.88]; internal medicine IMGs: OR, 0.85 [95% CI, 0.77-0.93]; and pediatric IMGs: OR, 0.85 [95% CI, 0.78-0.93]). Practicing in a state that expanded Medicaid by 2016 was associated with higher odds of prescribing hormonal contraception for family medicine (OR 1.50; 95% CI, 1.06-2.12) and internal medicine (OR, 1.71; 95% CI, 1.18-2.48) physicians but not for physicians from other specialties.

Conclusions and Relevance

In this cross-sectional study of primary care physicians, physician- and community-level factors, such as specialty, age, and the Medicaid expansion status of their state, were significantly associated with how they provided contraceptive services to Medicaid beneficiaries. However, the existence of associations varied across clinical specialties. Ensuring access to contraception among Medicaid beneficiaries may therefore require policy and program approaches tailored for different physician types.

Disparities in Elective Spine Surgery for Medicaid Beneficiaries: A Systematic Review

STUDY DESIGN

Systematic review.

OBJECTIVES

We sought to synthesize the literature investigating the disparities that Medicaid patients sustain with regards to 2 types of elective spine surgery, lumbar fusion (LF) and anterior cervical discectomy and fusion (ACDF).

METHODS

Our review was constructed in accordance with Preferred Reporting Items and Meta-analyses (PRISMA) guidelines and protocol. We systematically searched PubMed, Embase, Scopus, CINAHL, and Web of Science databases. We included studies comparing Medicaid beneficiaries to other payer categories with regards to rates of LF and ACDF, costs/reimbursement, and health outcomes.

RESULTS

A total of 573 articles were assessed. Twenty-five articles were included in the analysis. We found that the literature is consistent with regards to Medicaid disparities. Medicaid was strongly associated with decreased access to LF and ACDF, lower reimbursement rates, and worse health outcomes (such as higher rates of readmission and emergency department utilization) compared to other insurance categories.

CONCLUSIONS

In adult patients undergoing elective spine surgery, Medicaid insurance is associated with wide disparities with regards to access to care and health outcomes. Efforts should focus on identifying causes and interventions for such disparities in this vulnerable population.

Adoption of Patient-Reported Outcomes by Health Systems and Physician Practices in the USA

BACKGROUND

Patient-reported outcome measures (PROs) can help clinicians adjust treatments and deliver patient-centered care, but organizational adoption of PROs remains low.

OBJECTIVE

This study examines the extent of PRO adoption among health systems and physician practices nationally and examines the organizational capabilities associated with more extensive PRO adoption.

DESIGN

Two nationally representative surveys were analyzed in parallel to assess health system and physician practice capabilities associated with adoption of PROs of disability, pain, and depression.

PARTICIPANTS

A total of 323 US health system and 2,190 physician practice respondents METHODS: Multivariable regression models separately estimated the association of health system and physician practice capabilities associated with system-level and practice-level adoption of PROs.

MAIN MEASURES

Health system and physician practice adoption of PROs for depression, pain, and disability.

KEY RESULTS

Pain (50.6%) and depression (43.8%) PROs were more commonly adopted by all hospitals and medical groups within health systems compared to disability PROs (26.5%). In adjusted analyses, systems with more advanced health IT functions were more likely to use disability (p<0.05) and depression (p<0.01) PROs than systems with less advanced health IT. Practice-level advanced health IT was positively associated with use of depression PRO (p<0.05), but not disability or pain PRO use. Practices with more chronic care management processes, broader medical and social risk screening, and more processes to support patient responsiveness were more likely to adopt each of the three PROs. Compared to independent physician practices, system-owned practices and community health centers were less likely to adopt PROs.

CONCLUSIONS

Chronic care management programs, routine screening, and patient-centered care initiatives can enable PRO adoption at the practice level. Developing these practice-level capabilities may improve PRO adoption more than solely expanding health IT functions.

The Association of Readmission Reduction Activities with Primary Care Practice Readmission Rates

BACKGROUND

A great deal of research has focused on how hospitals influence readmission rates. While hospitals play a vital role in reducing readmissions, a significant portion of the work also falls to primary care practices. Despite this critical role of primary care, little empirical evidence has shown what primary care characteristics or activities are associated with reductions in hospital admissions.

OBJECTIVE

To examine the relationship between practices' readmission reduction activities and their readmission rates.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective study of 1,788 practices who responded to the National Survey of Healthcare Organizations and Systems (fielded 2017-2018) and 415,663 hospital admissions for Medicare beneficiaries attributed to those practices from 2016 100% Medicare claims data. We constructed mixed-effects logistic regression models to estimate practice-level readmission rates and a linear regression model to evaluate the association between practices' readmission rates with their number of readmission reduction activities.

INTERVENTIONS

Standardized composite score, ranging from 0 to 1, representing the number of a practice's readmission reduction capabilities. The composite score was composed of 12 unique capabilities identified in the literature as being significantly associated with lower readmission rates (e.g., presence of care manager, medication reconciliation, shared-decision making, etc.).

MAIN OUTCOMES AND MEASURES

Practices' readmission rates for attributed Medicare beneficiaries.

KEY RESULTS

Routinely engaging in more readmission reduction activities was significantly associated (P < .05) with lower readmission rates. On average, practices experienced a 0.05 percentage point decrease in readmission rates for each additional activity. Average risk-standardized readmission rates for practices performing 10 or more of the 12 activities in our composite measure were a full percentage point lower than risk-standardized readmission rates for practices engaging in none of the activities.

CONCLUSIONS

Primary care practices that engaged in more readmission reduction activities had lower readmission rates. These findings add to the growing body of evidence suggesting that engaging in multiple activities, rather than any single activity, is associated with decreased readmissions.

In Medicaid Managed Care Networks, Care Is Highly Concentrated Among A Small Percentage Of Physicians

States have increasingly outsourced the provision of Medicaid services to private managed care plans. To ensure that plans maintain access to care, many states set network adequacy standards that require plans to contract with a minimum number of physicians. In this study we used data from the period 2015-17 for four states to assess the level of Medicaid participation among physicians listed in the provider network directories of each managed care plan. We found that about one-third of outpatient primary care and specialist physicians contracted with Medicaid managed care plans in our sample saw fewer than ten Medicaid beneficiaries in a year. Care was highly concentrated: 25 percent of primary care physicians provided 86 percent of the care, and 25 percent of specialists, on average, provided 75 percent of the care. Our findings suggest that current network adequacy standards might not reflect actual access; new methods are needed that account for beneficiaries' preferences and physicians' willingness to serve Medicaid patients.

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.
