Long-Term Engagement of Patients With Advanced Cancer: Results From the EPAC Randomized Clinical Trial.

Importance: The long-term effect of interventions that assist patients with establishing their end-of-life care preferences among patients with cancer remain relatively unknown. Objective: To evaluate the association of a long-term intervention of a lay health worker-led advance care planning intervention among patients with advanced stages of cancer with overall survival and end-of-life health care use and costs. Design, Setting, and Participants: This follow-up study of the EPAC randomized clinical trial conducted between August 2013 and February 2015 used data from 9.4 years after the first patient was enrolled with a data cut-off date of February 1, 2023. Overall, 213 participants with stage 3 or 4 or recurrent cancer in the US Veterans Affairs Palo Alto Health Care System were included. Interventions: A 6-month lay health worker-led education and support intervention to assist patients with establishing their end-of-life preferences vs usual care. Main Outcomes and Measures: The outcomes of interest were overall survival, risk of death, restricted mean survival time, and palliative care, hospice, and acute care use in the final 30 days before death for participants who died. Results: Among 213 participants randomized and included in the intention-to-treat analysis, the mean (SD) age was 69.3 (9.1) years; 211 (99.1%) were male, 2 (0.90%) were female. There were no demographic or clinical characteristic imbalances at enrollment. As of February 1, 2023, 188 had died. The intervention group had a 25% reduction in risk of death (hazard ratio, 0.75; 95% CI, 0.56-0.98); more palliative care (44 [50.0%] vs 35 [35.0%]) and hospice use (64 [72.7%] vs 53 [53.0%]); and lower emergency department use (20 [22.7%] vs 47 [47.0%]), hospitalizations (17 [19.3%] vs 46 [46.0%]), and median (IQR) total health care costs (median [IQR], $1637 [$383-$9026] vs $18 520 [$4790-$50 729]) than control group participants. Conclusions and Relevance: The effects of the lay health worker-led intervention remain durable, with nearly complete follow-up, supporting integration into routine cancer care. Trial Registration: ClinicalTrials.gov Identifier: NCT02966509.

Changes in emergency department use associated with Medicaid expansion under the Affordable Care Act: A comparison of waiver and traditional expansion states.

Objective: To determine whether changes in emergency department use associated with Medicaid expansions differed between states undergoing waiver and traditional expansions. Methods: Design: This study was a cross-sectional difference-in-difference and event studies of Medicaid Expansion among states that expanded during or after 2014. Setting: We used a nationally representative cross-sectional survey from all 50 United States and the District of Columbia from 2010 to 2016. Participants: Adults aged 19-65 years with incomes <138% of the federal poverty level were included. Main Outcomes and Measures: Main outcomes were self-reported emergency department (ED) utilization in the last 12 months. Results: Individuals in states across all expansion types were not more likely to report any ED use in the previous year (2.8 percentage point increase [0.0-5.5], P = 0.052) but were more likely to report visiting an ED 2 times or more in the previous year (2.0 [0.0-4.1], P = 0.049) than those in non-expansion states. Individuals in states undergoing traditional expansions likewise were not more likely to report any ED use (2.2 [-0.7 to 1.5], P = 0.136) but were more likely to report visiting an ED 2 times or more in the previous year (2.3 [0.1-4.4], P = 0.038). Conversely, individuals in waiver states were more likely to report increase in any ED use (5.6 [0.3-11.0], P = 0.038), but were not more likely to report use of EDs 2 times or more in the previous year (0.8 [-3.2-4.9], P = 0.688). The differences between traditional and waiver states in any ED use and ED use 2 times or more in the previous 12 months were not statistically significant (P = 0.215 and P = 0.501, respectively). Conclusions: Three years after expanding Medicaid under the Affordable Care Act, there is little evidence of differences between traditional and waiver expansion states in changes in any ED use or intensive ED use. Future studies should investigate longer term changes in ED use.

Association Between Cervical Cancer Screening Guidelines and Preterm Delivery Among Females Aged 18 to 24 Years.

Importance: Cervical cancer screening is associated with reduced cervical cancer mortality; however, clinical trials have also shown an association between excisional procedures for cervical neoplasia and an increased risk of preterm delivery (PTD). National screening guidelines must weigh adverse effects on birth outcomes against benefits of cancer prevention. Objective: To ascertain the population-level association between the number of guideline-recommended cervical cancer screenings and downstream PTD risk among females aged 18 to 24 years. Design, Setting, and Participants: This cross-sectional study used a difference-in-differences approach based on variation in the recommended number of cervical cancer screenings (over time and across individuals giving birth at different ages) to estimate the association between the cumulative recommended number of screenings (by the time of childbirth) and PTD risk. National Vital Statistics System data from females aged 18 to 24 years who had a singleton, nulliparous birth in the US between 1996 and 2018 were used. Regression models were adjusted for maternal educational level, race and ethnicity, comorbidities, marital status, and prenatal care visits. Data were analyzed between June 2020 and March 2023. Exposure: A constructed variable capturing the cumulative number of guideline-recommended cervical cancer screenings for an individual based on their age and year of childbirth. Main Outcomes and Measures: Binary indicators for PTD and very preterm delivery (VPTD), defined as delivery before 37 and 34 weeks' gestational age, respectively, and gestational age was measured in weeks from the first day of the last menstrual period. Results: Among 11 333 151 females aged 18 to 24 years who gave birth between 1996 and 2018, 2 069 713 were Black (18.3%), 2 601 225 were Hispanic (23.0%), 6 068 498 were White (53.5%) individuals, and 593 715 (5.2%) were individuals of other race or ethnicity (Alaska Native; American Indian; Asian; Pacific Islander; multiracial; or unknown or missing race or ethnicity). Mean (SD) age was 20.9 (1.9) years, and 766 001 individuals (6.8%) had hypertension or diabetes. The mean (SD) number of guideline-recommended screenings by time of childbirth was 2.4 (2.2). Overall, PTD and VPTD occurred in 1 140 490 individuals (10.1%) and 333 040 (2.9%) of births, respectively. One additional recommended screening was associated with a 0.073 (95% CI, 0.026-0.120) percentage-point increase in PTD risk but no statistically significant change in VPTD risk. Females with hypertension or diabetes had a higher increase in PTD risk than those without these comorbidities (0.26 [95% CI, 0.11-0.4] vs 0.06 [95% CI, 0.01-0.10] percentage points; Wald test P < .001). Conclusions and Relevance: Findings of this cross-sectional study suggest that additional recommended cervical cancer screenings before birth were associated with an increased risk of PTD. These results can be used in future simulation models integrating oncological trade-offs to help ascertain optimal screening strategies.

Health Care Use and Spending Among Need-Based Subgroups of Medicare Beneficiaries With Full Medicaid Benefits.

Importance: Beneficiaries dual eligible for Medicare and Medicaid account for a disproportionate share of expenditures due to their complex care needs. Lack of coordination between payment programs creates misaligned incentives, resulting in higher costs, fragmented care, and poor health outcomes. Objective: To inform the design of integrated programs by describing the health care use and spending for need-based subgroups in North Carolina's full benefit, dual-eligible population. Design, Setting, and Participants: This cross-sectional study using Medicare and North Carolina Medicaid 100% claims data (2014-2017) linked at the individual level included Medicare beneficiaries with full North Carolina Medicaid benefits. Data were analyzed between 2021 and 2022. Exposure: Need-based subgroups: community well, home- and community-based services (HCBS) users, nursing home (NH) residents, and intensive behavioral health (BH) users. Measures: Medicare and Medicaid utilization and spending per person-year (PPY). Results: The cohort (n = 333 240) comprised subgroups of community well (64.1%, n = 213 667), HCBS users (15.0%, n = 50 095), BH users (15.2%, n = 50 509), and NH residents (7.5%, n = 24 927). Overall, 61.1% reported female sex. The most common racial identities included Asian (1.8%), Black (36.1%), and White (58.7%). Combined spending for Medicare and Medicaid was $26 874 PPY, and the funding of care was split evenly between Medicare and Medicaid. Among need-based subgroups, combined spending was lowest among community well at $19 734 PPY with the lowest portion (38.5%) of spending contributed by Medicaid ($7605). Among NH residents, overall spending ($68 359) was highest, and the highest portion of spending contributed by Medicaid (70.1%). Key components of spending among HCBS users' combined total of $40 069 PPY were clinician services on carrier claims ($14 523) and outpatient facility services ($9012). Conclusions and relevance: Federal and state policy makers and administrators are developing strategies to integrate Medicare- and Medicaid-funded health care services to provide better care to the people enrolled in both programs. Substantial use of both Medicare- and Medicaid-funded services was found across all need-based subgroups, and the services contributing a high proportion of the total spending differed across subgroups. The diversity of health care use suggests a tailored approach to integration strategies with comprehensive set benefits that comprises Medicare and Medicaid services, including long-term services and supports, BH, palliative care, and social services.

Employer-Sponsored Coverage Stabilized And Uninsurance Declined In The Second Year Of The COVID-19 Pandemic.

The health risks of COVID-19, combined with widespread economic instability in the US, spurred Congress to pass temporary measures to improve access to health insurance. Using data from the Household Pulse Survey, a high-frequency, population-based survey, we examined trends in health coverage during 2021 and early 2022 among nonelderly adults. We estimated that eight million people gained coverage during this period, primarily because of increases in Medicaid and other public coverage. Despite rising employment, rates of employer-sponsored coverage remained flat. In Medicaid expansion states, employment rates increased significantly among Medicaid enrollees. Our results suggest that when the public health emergency ends, many people currently enrolled in Medicaid might no longer be eligible, particularly in Medicaid expansion states. Policy makers and employers should be prepared to help people who lose Medicaid eligibility identify and navigate enrollment in alternative sources of health insurance, including both Affordable Care Act Marketplace and employer-sponsored coverage.

Medication Payments by Insurers and Patients for the Treatment of Metastatic Castrate-Resistant Prostate Cancer.

PURPOSE: The implications of high prices for cancer drugs on health care costs and patients' financial burdens are a growing concern. Patients with metastatic castrate-resistant prostate cancer (mCRPC) are often candidates for multiple first-line systemic therapies with similar impacts on life expectancy. However, little is known about the gross and out-of-pocket (OOP) payments associated with each of these drugs for patients with employer-sponsored health insurance. We therefore aimed to determine the gross and OOP payments of first-line drugs for mCRPC and how the payments vary across drugs. METHODS: This retrospective cohort study included 4,298 patients with prostate cancer who initiated therapy with one of six drugs approved for first-line treatment of mCRPC between July 1, 2013, and June 30, 2019. We compared gross and OOP payments during the 6 months after initiation of treatment for mCRPC using private payer claims data across patients using different first-line drugs. RESULTS: Gross payments varied across drugs. Over the 6 months after the index prescription, mean unadjusted gross drug payments were highest for patients receiving sipuleucel-T ($115,525 USD) and lowest for patients using docetaxel ($12,804 USD). OOP payments were lower than gross drug payments; mean 6-month OOP payments were highest for cabazitaxel ($1,044 USD) and lowest for docetaxel ($296 USD). There was a wide distribution of OOP payments within drug types. CONCLUSION: Drugs for mCRPC are expensive with large differences in payments by drug type. OOP payments among patients with employer-sponsored health insurance are much lower than gross drug payments, and they vary both across and within first-line drug types, with some patients making very high OOP payments. Although lowering drug prices would reduce pharmaceutical spending for patients with mCRPC, decreasing patient financial burden requires understanding an individual patient's benefit design.

Association Between High-Deductible Health Plans and Hernia Acuity.

IMPORTANCE: About half of people younger than 65 years with private insurance are enrolled in a high-deductible health plan (HDHP). While these plans entail substantially higher out-of-pocket costs for patients with chronic medical conditions who require ongoing care, their effect on patients undergoing surgery who require acute care is poorly understood. It is plausible that higher out-of-pocket costs may lead to delays in care and more complex surgical conditions. OBJECTIVE: To determine the association between enrollment in HDHPs and presentation with incarcerated or strangulated hernia. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort analysis included privately insured patients aged 18 to 63 years from a large commercial insurance claims database who underwent a ventral or groin hernia operation from January 2016 through June 2019 and classified their coverage as either a traditional health plan or an HDHP per the Internal Revenue Service's definition. Multivariable regression, adjusting for demographic and clinical covariates, was used to examine the association between enrollment in an HDHP and the primary outcome of presentation with an incarcerated or strangulated hernia. EXPOSURES: Traditional health plan vs HDHP. MAIN OUTCOMES AND MEASURES: Presence of an incarcerated or strangulated hernia per International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis codes. RESULTS: Among 83 281 patients (71.9% men and 28.1% women; mean [SD] age, 48.7 [10.9] years) who underwent hernia surgery, 27 477 (33.0%) were enrolled in an HDHP and 21 876 (26.2%) had a hernia that was coded as incarcerated or strangulated. The mean annual deductible was considerably higher for those in the HDHP group than their traditional health plan counterparts (unadjusted mean [SD], $3635 [$2094] vs $705 [$737]; adjusted, -$2931; P < .001). Patients in the HDHP group were more likely to present with an incarcerated or strangulated hernia (adjusted odds ratio, 1.07; 95% CI, 1.03-1.11; P < .001). CONCLUSIONS AND RELEVANCE: In this cohort study, enrollment in an HDHP was associated with higher odds of presenting with an incarcerated or strangulated hernia, which is more likely to require emergency surgery that precludes medical optimization. These data suggest that, among patients with groin and ventral hernias, enrollment in an HDHP may be associated with delays in surgical care that result in complex disease presentation.

The Role of Physician-Driven Device Preference in the Cost Variation of Common Interventional Radiology Procedures.

PURPOSE: To analyze the impact of physician-specific equipment preference on cost variation for procedures typically performed by interventional radiologists at a tertiary care academic hospital. MATERIALS AND METHODS: From October 2017 to October 2019, data on all expendable items used by 9 interventional radiologists for 11 common interventional radiology procedure categories were compiled from the hospital analytics system. This search yielded a final dataset of 44,654 items used in 2,121 procedures of 11 different categories. The mean cost per case for each physician as well as the mean, standard deviation, and coefficient of variation (CV) of the mean cost per case across physicians were calculated. The proportion of spending by item type was compared across physicians for 2 high-variation, high-volume procedures. The relationship between the mean cost per case and case volume was examined using linear regression. RESULTS: There was a high variability within each procedure, with the highest and the lowest CV for radioembolization administration (56.6%) and transjugular liver biopsy (4.9%), respectively. Variation in transarterial chemoembolization cost was mainly driven by microcatheters/microwires, while for nephrostomy, the main drivers were catheters/wires and access sets. Mean spending by physician was not significantly correlated with case volume (P =.584). CONCLUSIONS: Physicians vary in their item selection even for standard procedures. While the financial impact of these differences vary across procedures, these findings suggest that standardization may offer an opportunity for cost savings.

Trends in US Health Insurance Coverage During the COVID-19 Pandemic.

Importance: While most working-age adults in the US obtain health insurance through an employer, little is known about the implications of the massive pandemic-related job loss in March 2020 and subsequent rebound for rates of employer-sponsored coverage and uninsurance. Objective: To determine how health insurance coverage changed during the COVID-19 pandemic. Design Setting and Participants: Analysis of trends in insurance coverage based on repeated cross sections of the US Census Bureau's Household Pulse Survey data, using linear regression to adjust for respondent's demographic and socioeconomic characteristics and state of residence. More than 1.2 million US adults aged 18 to 64 years were surveyed from April 23 through December 21, 2020. Exposures: The COVID-19 pandemic, separated into spring and summer and fall and winter time periods during 2020, as well as state Medicaid expansion status. Main Outcomes and Measures: Regression-based estimates of the weekly percentage-point change in respondents' health insurance status, including having any health insurance, any employer-sponsored health insurance, or only nonemployer sponsored coverage. Nonemployer-sponsored coverage is categorized into private, Medicaid, and other public in some analyses. Results: The study population included 1 212 816 US adults (51% female; mean [SD] age, 42 [13] years) across all 50 US states and Washington DC. Among these respondents, rates of employer-sponsored coverage declined by 0.2 percentage points each week during the COVID-19 pandemic. Other types of coverage, particularly from public sources, increased by 0.1 and 0.2 percentage points in the spring and summer and fall and winter periods, respectively. Overall, health insurance coverage of any type declined, particularly during the spring and summer period, during which uninsurance increased by 1.4 percentage points, representing more than 2.7 million newly uninsured people, over a 12-week period. Conclusions and Relevance: In this cross-sectional study of data from the US Census Bureau's Household Pulse Survey, results showed that while public programs played an important role in protecting US adults from pandemic-driven declines in employment-sponsored coverage, many people became uninsured during 2020.

Analysis of Publicly Funded Reinsurance-Government Spending and Insurer Risk Exposure.

This analysis compares the design of section 1332 reinsurance policies across states based on their potential for reducing insurer risk exposure and likely level of government spending.

Cataract Surgery Complexity and Surgical Complication Rates Among Medicare Beneficiaries With and Without Dementia.

PURPOSE: To evaluate cataract surgery complexity and complications among US Medicare beneficiaries with and without dementia. DESIGN: Retrospective claims-based cohort study. PARTICIPANTS: A 20% representative sample of Medicare beneficiaries, 2006-2015. METHODS: Dementia was identified from diagnosis codes on or prior to each beneficiary's first-eye cataract surgery. For each surgery, we identified setting, routine vs complex coding, anesthesia provider type, duration, and any postoperative hospitalization. We evaluated 30- and 90-day complication rates-return to operating room, endophthalmitis, suprachoroidal hemorrhage, retinal detachment, retinal tear, macular edema, glaucoma, or choroidal detachment-and used adjusted regression models to evaluate likelihood of surgical characteristics and complications. Complication analyses were stratified by second-eye cataract surgery within 90 days postoperatively. RESULTS: We identified 457,128 beneficiaries undergoing first-eye cataract surgery, 23,332 (5.1%) with dementia. None of the evaluated surgical complications were more likely in dementia-diagnosed beneficiaries. There was also no difference in likelihood of nonambulatory surgery center setting, anesthesiologist provider, or postoperative hospitalization. Dementia-diagnosed beneficiaries were more likely to have surgeries coded as complex (15.6% of cases vs 8.8%, P < .0001), and surgeries exceeding 30 minutes (OR = 1.21, 95% CI = 1.17-1.25). CONCLUSIONS: Among US Medicare beneficiaries undergoing cataract surgery, those with dementia are more likely to have "complex" surgery" lasting more than 30 minutes. However, they do not have greater likelihood of surgical complications, higher-acuity setting, advanced anesthesia care, or postoperative hospitalization. This may be influenced by case selection and may suggest missed opportunities to improve vision. Future research is needed to identify dementia patients likely to benefit from cataract surgery.

ACA Medicaid Expansion Associated With Increased Medicaid Participation and Improved Health Among Near-Elderly: Evidence From the Health and Retirement Study.

The Affordable Care Act (ACA) dramatically expanded health insurance, but questions remain regarding its effects on health. We focus on older adults for whom health insurance has greater potential to improve health and well-being because of their greater health care needs relative to younger adults. We further focus on low-income adults who were the target of the Medicaid expansion. We believe our study provides the first evidence of the health-related effects of ACA Medicaid expansion using the Health and Retirement Study (HRS). Using geo-coded data from 2010 to 2016, we estimate difference-in-differences models, comparing changes in outcomes before and after the Medicaid expansion in treatment and control states among a sample of over 3,000 unique adults aged 50 to 64 with income below 100% of the federal poverty level. The HRS allows us to examine morbidity outcomes not available in administrative data, providing evidence of the mechanisms underlying emerging evidence of mortality reductions due to expanded insurance coverage among the near-elderly. We find that the Medicaid expansion was associated with a 15 percentage point increase in Medicaid coverage which was largely offset by declines in other types of insurance. We find improvements in several measures of health including a 12% reduction in metabolic syndrome; a 32% reduction in complications from metabolic syndrome; an 18% reduction in the likelihood of gross motor skills difficulties; and a 34% reduction in compromised activities of daily living (ADLs). Our results thus suggest that the Medicaid expansion led to improved physical health for low-income, older adults.

Receipt of Eye Care Services among Medicare Beneficiaries with and without Dementia.

PURPOSE: To examine the relationship between dementia status and receipt of eye care among US Medicare beneficiaries. DESIGN: Retrospective, claims-based analysis. PARTICIPANTS: A 20% representative sample of Medicare beneficiaries who received care between January 1, 2006, and December 31, 2015. METHODS: Dementia was identified from diagnosis codes documented in a beneficiary's first 3 years of observed Medicare enrollment. Eye care visits were identified from provider specialty codes on each encounter claim. We used multivariable Cox proportional hazards regression models with time-varying covariates to compare the likelihood of receiving eye care between beneficiaries with and without dementia. All models were adjusted for potential confounders, including demographics, urban/rural residence, systemic health (Charlson Index), and ocular comorbidities. MAIN OUTCOME MEASURES: Hazard ratio (HR) and 95% confidence interval (CI) for (1) being seen by any eye care provider (ophthalmologist or optometrist); (2) being seen by an ophthalmologist specifically; and (3) receiving cataract surgery (among beneficiaries with ophthalmologist encounters). RESULTS: A total of 4 451 200 beneficiaries met inclusion criteria; 3 805 718 (85.5%) received eye care during the study period, and 391 556 (8.8%) had diagnosed dementia. Some 73.4% of beneficiaries diagnosed with dementia saw an eye care provider during the study period and 55.4% saw an ophthalmologist versus 86.7% and 74.0% of beneficiaries, respectively, without dementia diagnoses. Compared with those without dementia diagnoses, beneficiaries with diagnosed dementia had lower likelihood of seeing any eye care provider (adjusted HR, 0.69; 95% CI, 0.69-0.70) and were less likely to see an ophthalmologist (adjusted HR, 0.55; 95% CI, 0.55-0.55). Among the subset of beneficiaries who did see ophthalmologists, those with diagnosed dementia were also less likely to receive cataract surgery than beneficiaries without diagnosed dementia (HR, 0.62; 95% CI, 0.62-0.63) and less likely to receive a cataract diagnosis (18% vs. 82%). CONCLUSIONS: US Medicare beneficiaries diagnosed with dementia are less likely to receive eye care than those without diagnosed dementia. Depending on visual acuity and functional status, this may have implications for injury prevention, physical and cognitive function, and quality of life. Further work is needed to identify barriers to receiving eye care, determine eye care services and settings that provide greatest value to patients with dementia, and implement measures to improve access to appropriate eye care.

The effects of medicare advantage on opioid use.

Despite a vast literature on the determinants of prescription opioid use, the role of health insurance plans has received little attention. We study how the form of Medicare beneficiaries' drug coverage affects the volume of opioids they consume. We find that enrollment in Medicare Advantage, which integrates drug coverage with other medical benefits, significantly reduces beneficiaries' likelihood of filling an opioid prescription, as compared to enrollment in a stand-alone drug plan. Approximately half of this effect was due to fewer fills from prescribers who write a very large number of opioid prescriptions.

Association Between HEDIS Performance and Primary Care Physician Age, Group Affiliation, Training, and Participation in ACA Exchanges.

BACKGROUND: There are a limited number of studies investigating the relationship between primary care physician (PCP) characteristics and the quality of care they deliver. OBJECTIVE: To examine the association between PCP performance and physician age, solo versus group affiliation, training, and participation in California's Affordable Care Act (ACA) exchange. DESIGN: Observational study of 2013-2014 data from Healthcare Effectiveness Data and Information Set (HEDIS) measures and select physician characteristics. PARTICIPANTS: PCPs in California HMO and PPO practices (n = 5053) with part of their patient panel covered by a large commercial health insurance company. MAIN MEASURES: Hemoglobin A1c testing; medical attention nephropathy; appropriate treatment hypertension (ACE/ARB); breast cancer screening; proportion days covered by statins; monitoring ACE/ARBs; monitoring diuretics. A composite performance measure also was constructed. KEY RESULTS: For the average 35- versus 75-year-old PCP, regression-adjusted mean composite relative performance scores were at the 60th versus 47th percentile (89% vs. 86% composite absolute HEDIS scores; p < .001). For group versus solo PCPs, scores were at the 55th versus 50th percentiles (88% vs. 87% composite absolute HEDIS scores; p < .001). The effect of age on performance was greater for group versus solo PCPs. There was no association between scores and participation in ACA exchanges. CONCLUSIONS: The associations between population-based care performance measures and PCP age, solo versus group affiliation, training, and participation in ACA exchanges, while statistically significant in some cases, were small. Understanding how to help older PCPs excel equally well in group practice compared with younger PCPs may be a fruitful avenue of future research.

Does Multispecialty Practice Enhance Physician Market Power?

In health care, vertical integration - common ownership of producers of complementary services - may have both pro- and anti-competitive effects. We use data on 40 million commercially-insured individuals from the Health Care Cost Institute to construct price indices for office visits to general-practice and specialist physicians for the years 2008-2012. Controlling for generalist market concentration, we find that generalists charge higher prices when they are integrated with specialists, and that the effect of integration is larger in more concentrated specialist markets. Conversely, controlling for specialist market concentration, specialists charge higher prices when integrated with generalists, with larger effects in more concentrated generalist markets. Our results suggest that multispecialty practice enhances physician market power.

Comparative Usability Study of a Newly Created Patient-Centered Tool and Medicare.gov Plan Finder to Help Medicare Beneficiaries Choose Prescription Drug Plans.

INTRODUCTION: In response to reported difficulties in selecting a Medicare Part D prescription drug plan, we designed a patient-centered online Part D plan selection tool (CHOICE1.0) to simplify the selection process and to provide personalized, expert recommendations. METHODS: This ethnographic comparative usability study observed 44 patients using the first version of the tool during Medicare 2016 Open Enrollment. Participants were observed as they chose their drug plan using Medicare.gov and 1 of 3 versions of CHOICE1.0 that varied in amount of expert guidance. Descriptive statistics were used to analyze exit survey data. The observations were video-recorded, and field notes were analyzed thematically. RESULTS: Participants were significantly more satisfied with CHOICE1.0 for choosing a plan, understanding information, and ease of use compared to Medicare.gov. Those using expert versions of CHOICE1.0 were more likely to indicate their intention to switch plans than those using Medicare.gov, though they wanted to know the source and content. CONCLUSION: The more patient-centered prescription drug choice tool improved user experience and enabled users to choose plans more consistent with expert recommendations.

Differences in Cataract Surgery Rates Based on Dementia Status.

BACKGROUND: Cataract surgery substantially improves patient quality of life. Despite the rising prevalence of dementia in the US, little is known about use of cataract surgery among this group. OBJECTIVE: To evaluate the relationship between dementia status and cataract surgery. METHODS: Using administrative insurance claims for a representative sample of 1,125,387 US Medicare beneficiaries who received eye care between 2006 and 2015, we compared cataract surgery rates between patients with and without dementia via multivariable regression models to adjust for patient characteristics. Main outcome measures were annual rates of cataract surgery and hazard ratio and 95% confidence interval (CI) for receiving cataract surgery. RESULTS: Cataract surgery was performed in 457,128 patients, 23,331 with a prior diagnosis of dementia. 16.7% of dementia patients underwent cataract surgery, compared to 43.8% of patients without dementia. 59 cataract surgeries were performed per 1000 dementia patients annually, versus 105 surgeries per 1000 nondementia patients. After adjusting for patient characteristics, dementia patients were approximately half as likely to receive cataract surgery compared to nondementia patients (adjusted HR = 0.53, 95% CI 0.53-0.54). Among the subset of patients who received a first cataract surgery, those with dementia were also less likely to receive second-eye cataract surgery (adjusted HR = 0.87, 95% CI 0.86-0.88). CONCLUSION: US Medicare patients with dementia are less likely to undergo cataract surgery than those without dementia. This finding has implications for quality of care and dementia progression. More information is necessary to understand why rates of cataract surgery are lower for these patients, and to identify conditions where benefits of surgery may outweigh risks.

Machine-Based Expert Recommendations And Insurance Choices Among Medicare Part D Enrollees.

Choosing a health insurance plan is difficult for many people, and patient-centered decision support may help consumers make these choices. We tested whether providing a patient-centered decision-support tool-with or without machine-based, personalized expert recommendations-influenced decision outcomes for Medicare Part D enrollees. We found that providing an online patient-centered decision-support tool increased older adults' satisfaction with the process of choosing a prescription drug plan and the amount of time they spent choosing a plan. Providing personalized expert recommendations as well increased rates of plan switching. Many people who could have accessed the tool chose not to, and the characteristics of people who used the tool differed from those who did not. We conclude that a patient-centered decision-support tool providing personalized expert recommendations can help people choose a plan, but different approaches may be necessary to encourage more people to periodically reevaluate their options.

Sex Differences in Treatment Strategies Among Patients With Ulcerative Colitis: A Retrospective Cohort Analysis of Privately Insured Patients.

BACKGROUND: Sex-based treatment disparities occur in many diseases. Women undergo fewer procedural interventions, and their care is less consistent with guideline-based therapy. There is limited research exploring sex-based differences in ulcerative colitis treatment. We hypothesized that women are less likely to be treated with strategies consistent with long-term disease remission, including surgery and maintenance medications. OBJECTIVE: The aim of this study was to determine if patient sex is associated with choice of treatment strategy for ulcerative colitis. DESIGN: This is a retrospective cohort analysis. SETTING: Data were gathered from a large commercial insurance claims database from 2007 to 2015. PATIENTS: We identified a cohort of 38,851 patients newly diagnosed with ulcerative colitis, aged 12 to 64 years with at least 1 year of follow-up. MAIN OUTCOME MEASURES: The primary outcomes measured were the differences between male and female patients in 1) rates and types of index ulcerative colitis operations, 2) rates and types of ulcerative colitis medication prescriptions, and 3) rates of opioid prescriptions. RESULTS: Men were more likely to undergo surgical treatment for ulcerative colitis (2.94% vs 1.97%, p < 0.001, OR 1.51, p < 0.001). The type of index operation performed did not vary by sex. Men were more likely to undergo treatment with maintenance medications, including biologic (12.4% vs 10.2%, p < 0.001, OR 1.22, p < 0.001), immunomodulatory (16.3% vs 14.9%, p < 0.001, OR 1.08, p = 0.006), and 5-aminosalicylate medications (67.0% vs 63.2%, p < 0.001, OR 1.18, p < 0.001). Women were more likely to undergo treatment with rescue therapies and symptomatic control with corticosteroids (55.5% vs 54.0%, p = 0.002, OR 1.07, p = 0.002) and opioids (50.2% vs 45.9%, p < 0.001, OR 1.17, p < 0.001). LIMITATIONS: Claims data lack clinical characteristics acting as confounders. CONCLUSIONS: Men with ulcerative colitis were more likely to undergo treatment consistent with long-term remission or cure, including maintenance medications and definitive surgery. Women were more likely to undergo treatment consistent with short-term symptom management. Further studies to explore underlying mechanisms of sex-related differences in ulcerative colitis treatment strategies and disease trajectories are warranted.
