Characteristics and outcomes associated with two asthma quality of care measures.

OBJECTIVE: We investigated asthma quality measures to understand patient characteristics associated with non-attainment of quality care and measure the association with asthma-related emergency department (ED) visits or inpatient hospitalizations (IPs). METHODS: Using administrative data from ALL Kids, Alabama's Children's Health Insurance Program, from 2013 to 2019 we calculated non-attainment of the Medication Management for Asthma (MMA) and Asthma Medication Ratio (AMR) quality measures. Patient characteristics and asthma-related ED visits and IPs associated with non-attainment of the MMA and AMR measures were assessed using logit regression models and Marginal effects at the mean. RESULTS: Among 2528 children with asthma, 53.2% failed to attain the MMA measure and 8.5% the AMR measure. Prior asthma-related ED visits or IP stays increased likelihood of non-attainment by 14.8 percentage points (95% CI 8.6-20.9) for MMA and 7.3 percentage points (95% CI 2.8-11.8) for AMR. Among 868 children (34.3%) with three years of continuous enrollment, AMR non-attainment was associated with a 6.1 percentage point increase in ED or IP utilization (95% CI 1.3-10.9), however MMA non-attainment was not associated with either outcome. Prior ED visit/IP stay was associated with a 17.2 percentage point (95% CI 8.3-26.1) increase in the likelihood of a subsequent ED visit/IP stay among those with non-attainment MMA and a 15.5 percentage point increase (95% CI 6.9-24.2) for non-attainment AMR. CONCLUSIONS: Patient characteristics associated with non-attainment of asthma quality measures presents actionable evidence to guide improvement efforts as non-attainment AMR increases the risk of subsequent ED visits and IP stays.

The effect of expanded insurance coverage under the Affordable Care Act on emergency department utilization in New York.

BACKGROUND: One of the proposed benefits of expanding insurance coverage under the Affordable Care Act (ACA) was a reduction in emergency department (ED) utilization for non-urgent visits related to lack of health insurance coverage and access to primary care providers. The objective of this study was to estimate the effect of the 2014 ACA implementation on ED use in New York. METHODS: We used the Healthcare Cost and Utilization Project State Emergency Department and State Inpatient Databases for all outpatient and all inpatient visits for patients admitted through an ED from 2011 to 2016. We focused on in-state residents aged 18 to 64, who were covered under Medicaid, private insurance, or were uninsured prior to the 2014 expansion. We estimated the effect of the expanded insurance coverage on average monthly ED visits volumes and visits per 1000 residents (rates) using interrupted time-series regression analyses. RESULTS: After ACA implementation, overall average monthly ED visits increased by around 3.0%, both in volume (9362; 95% Confidence Intervals [CI]: 1681-17,522) and in rates (0.80, 95% CI:0.12-1.49). Medicaid covered ED visits volume increased by 23,972 visits (95% CI: 16,240 -31,704) while ED visits by the uninsured declined by 13,297 (95% CI:-15,856 - -10,737), and by 1453 (95% CI:-4027-1121) for the privately insured. Medicaid ED visits rates per 1000 residents increased by 0.77 (95% CI:-1.96-3.51) and by 2.18 (95% CI:-0.55-4.92) for those remaining uninsured, while private insurance visits rates decreased by 0.48 (95% CI:-0.79 - -0.18). We observed increases in primary-care treatable ED visits and in visits related to mental health and alcohol disorders, substance use, diabetes, and hypertension. All estimated changes in monthly ED visits after the expansion were statistically significant, except for ED visit rates among Medicaid beneficiaries. CONCLUSION: Net ED visits by adults 18 to 64 years of age increased in New York after the implementation of the ACA. Large increases in ED use by Medicaid beneficiaries were partially offset by reductions among the uninsured and those with private coverage. Our results suggest that efforts to expand health insurance coverage only will be unlikely to reverse the increase in ED use.

US Privacy Laws Go Against Public Preferences and Impede Public Health and Research: Survey Study.

BACKGROUND: Reaping the benefits from massive volumes of data collected in all sectors to improve population health, inform personalized medicine, and transform biomedical research requires the delicate balance between the benefits and risks of using individual-level data. There is a patchwork of US data protection laws that vary depending on the type of data, who is using it, and their intended purpose. Differences in these laws challenge big data projects using data from different sources. The decisions to permit or restrict data uses are determined by elected officials; therefore, constituent input is critical to finding the right balance between individual privacy and public benefits. OBJECTIVE: This study explores the US public's preferences for using identifiable data for different purposes without their consent. METHODS: We measured data use preferences of a nationally representative sample of 504 US adults by conducting a web-based survey in February 2020. The survey used a choice-based conjoint analysis. We selected choice-based conjoint attributes and levels based on 5 US data protection laws (Health Insurance Portability and Accountability Act, Family Educational Rights and Privacy Act, Privacy Act of 1974, Federal Trade Commission Act, and the Common Rule). There were 72 different combinations of attribute levels, representing different data use scenarios. Participants were given 12 pairs of data use scenarios and were asked to choose the scenario they were the most comfortable with. We then simulated the population preferences by using the hierarchical Bayes regression model using the ChoiceModelR package in R. RESULTS: Participants strongly preferred data reuse for public health and research than for profit-driven, marketing, or crime-detection activities. Participants also strongly preferred data use by universities or nonprofit organizations over data use by businesses and governments. Participants were fairly indifferent about the different types of data used (health, education, government, or economic data). CONCLUSIONS: Our results show a notable incongruence between public preferences and current US data protection laws. Our findings appear to show that the US public favors data uses promoting social benefits over those promoting individual or organizational interests. This study provides strong support for continued efforts to provide safe access to useful data sets for research and public health. Policy makers should consider more robust public health and research data use exceptions to align laws with public preferences. In addition, policy makers who revise laws to enable data use for research and public health should consider more comprehensive protection mechanisms, including transparent use of data and accountability.

Adherence to Telemonitoring Therapy for Medicaid Patients With Hypertension: Case Study.

BACKGROUND: Almost 50% of the adults in the United States have hypertension. Although clinical trials indicate that home blood pressure monitoring can be effective in managing hypertension, the reported results might not materialize in practice because of patient adherence problems. OBJECTIVE: The aims of this study are to characterize the adherence of Medicaid patients with hypertension to daily telemonitoring, identify the impacts of adherence reminder calls, and investigate associations with blood pressure control. METHODS: This study targeted Medicaid patients with hypertension from the state of Texas. A total of 180 days of blood pressure and pulse data in 2016-2018 from a telemonitoring company were analyzed for mean transmission rate and mean blood pressure change. The first 30 days of data were excluded because of startup effects. The protocols required the patients to transmit readings by a specified time daily. Patients not transmitting their readings received an adherence reminder call to troubleshoot problems and encourage transmission. The patients were classified into adherent and nonadherent cohorts; adherent patients were those who transmitted data on at least 80% of the days. RESULTS: The mean patient age was 73.2 (SD 11.7) years. Of the 823 patients, 536 (65.1%) were women, and 660 (80.2%) were urban residents. The adherent cohort (475/823, 57.7%) had mean transmission rates of 74.9% before the adherence reminder call and 91.3% after the call, whereas the nonadherent cohort (348/823, 42.3%) had mean transmission rates of 39% and 58% before and after the call, respectively. From month 1 to month 5, the transmission rates dropped by 1.9% and 10.2% for the adherent and nonadherent cohorts, respectively. The systolic and diastolic blood pressure values improved by an average of 2.2 and 0.7 mm Hg (P<.001 and P=.004), respectively, for the adherent cohort during the study period, whereas only the systolic blood pressure value improved by an average of 1.6 mm Hg (P=.02) for the nonadherent cohort. CONCLUSIONS: Although we found that patients can achieve high levels of adherence, many experience adherence problems. Although adherence reminder calls help, they may not be sufficient. Telemonitoring lowered blood pressure, as has been observed in clinical trials. Furthermore, blood pressure control was positively associated with adherence.

The Effect of the Medicaid Expansion on Frequent Emergency Department Use in New York.

BACKGROUND: There is limited evidence on the effect of the Affordable Care Act (ACA) on frequent emergency department (ED) use. OBJECTIVES: To estimate the effect of the ACA Medicaid expansion on frequent ED use in New York. METHODS: We used data from the Healthcare Cost and Utilization Project State Emergency Department Databases and State Inpatient Databases from 2011 to 2016. A consistent and unique patient identifier enabled us to identify ED visits by the same patient across different facilities within the state for each calendar year. Multivariate logistic regressions were used to quantify the policy's effect on frequent ED use (≥ 4 ED visits/year). We included in-state residents 18 to 64 years of age who were covered by Medicaid, private insurance, or were uninsured. Sensitivity analyses were conducted using alternative definitions of frequent use. To validate the findings, a falsification analysis was also conducted using only the 3 pre-expansion years. RESULTS: Our study included 14.3 million ED patients with 23.8 million ED visits from 2011 to 2016. Frequent users (7.2%) accounted for 26.6% of all ED visits. The likelihood of frequent ED use declined by 4% among Medicaid beneficiaries (adjusted odds ratio [AOR] 0.96, 95% confidence intervals (CI) 0.95-0.97) and by 12% for the uninsured (AOR 0.88, 95% CI 0.86-0.89) in the post-expansion period, compared with the pre-expansion period. Private insurance enrollees were 9% more likely to exhibit frequent use in the post-expansion period (AOR 1.09, 95% CI 1.08-1.11). The sensitivity analyses yielded results similar to those of the main model. The falsification analyses revealed small and insignificant year-to-year changes in the 3 pre-expansion years. CONCLUSION: The likelihood of frequent ED use decreased 3 years after New York implemented the ACA Medicaid expansion, particularly for Medicaid beneficiaries and the uninsured, highlighting the importance of expanding health insurance and provisions tailored at high-need populations.

Mining Fiskeby III and Mandarin (Ottawa) Expression Profiles to Understand Iron Stress Tolerant Responses in Soybean.

The soybean (Glycine max L. merr) genotype Fiskeby III is highly resistant to a multitude of abiotic stresses, including iron deficiency, incurring only mild yield loss during stress conditions. Conversely, Mandarin (Ottawa) is highly susceptible to disease and suffers severe phenotypic damage and yield loss when exposed to abiotic stresses such as iron deficiency, a major challenge to soybean production in the northern Midwestern United States. Using RNA-seq, we characterize the transcriptional response to iron deficiency in both Fiskeby III and Mandarin (Ottawa) to better understand abiotic stress tolerance. Previous work by our group identified a quantitative trait locus (QTL) on chromosome 5 associated with Fiskeby III iron efficiency, indicating Fiskeby III utilizes iron deficiency stress mechanisms not previously characterized in soybean. We targeted 10 of the potential candidate genes in the Williams 82 genome sequence associated with the QTL using virus-induced gene silencing. Coupling virus-induced gene silencing with RNA-seq, we identified a single high priority candidate gene with a significant impact on iron deficiency response pathways. Characterization of the Fiskeby III responses to iron stress and the genes underlying the chromosome 5 QTL provides novel targets for improved abiotic stress tolerance in soybean.

Effects of spring temperatures on the strength of selection on timing of reproduction in a long-distance migratory bird.

Climate change has differentially affected the timing of seasonal events for interacting trophic levels, and this has often led to increased selection on seasonal timing. Yet, the environmental variables driving this selection have rarely been identified, limiting our ability to predict future ecological impacts of climate change. Using a dataset spanning 31 years from a natural population of pied flycatchers (Ficedula hypoleuca), we show that directional selection on timing of reproduction intensified in the first two decades (1980-2000) but weakened during the last decade (2001-2010). Against expectation, this pattern could not be explained by the temporal variation in the phenological mismatch with food abundance. We therefore explored an alternative hypothesis that selection on timing was affected by conditions individuals experience when arriving in spring at the breeding grounds: arriving early in cold conditions may reduce survival. First, we show that in female recruits, spring arrival date in the first breeding year correlates positively with hatch date; hence, early-hatched individuals experience colder conditions at arrival than late-hatched individuals. Second, we show that when temperatures at arrival in the recruitment year were high, early-hatched young had a higher recruitment probability than when temperatures were low. We interpret this as a potential cost of arriving early in colder years, and climate warming may have reduced this cost. We thus show that higher temperatures in the arrival year of recruits were associated with stronger selection for early reproduction in the years these birds were born. As arrival temperatures in the beginning of the study increased, but recently declined again, directional selection on timing of reproduction showed a nonlinear change. We demonstrate that environmental conditions with a lag of up to two years can alter selection on phenological traits in natural populations, something that has important implications for our understanding of how climate can alter patterns of selection in natural populations.

Turmoil in the Health Insurance Marketplaces.

The first three years of the Affordable Care Act's Health Insurance Marketplaces have been tumultuous ones, with rapid entry and exit of insurers and recent spikes in premiums. As concerns mount about the stability and viability of the Marketplaces, this brief provides some insight into the forces behind the headlines and presents six options for policymakers to consider.

The effects of direct-to-consumer advertising on medication use among Medicaid children with asthma.

Asthma medication adherence is low, particularly among Medicaid enrollees. There has been much debate on the impact of direct-to-consumer advertising (DTCA) on health care use, but the impact on medication use among children with asthma has been unexamined. The study sample included 180,584 children between the ages of 5 and 18 with an asthma diagnosis from a combined dataset of Medicaid Analytic eXtract and national advertising data. We found that DTCA expenditure during the study period was significantly associated with an increase in asthma medication use. However, the effectiveness declined after a certain level.

The impact of texting bans on motor vehicle crash-related hospitalizations.

We used a panel design and the Nationwide Inpatient Sample from 19 states between 2003 and 2010 to examine the impact of texting bans on crash-related hospitalizations. We conducted conditional negative binomial regressions with state, year, and month fixed effects to examine changes in crash-related hospitalizations in states after the enactment of a texting ban relative to those in states without such bans. Results indicate that texting bans were associated with a 7% reduction in crash-related hospitalizations among all age groups. Texting bans were significantly associated with reductions in hospitalizations among those aged 22 to 64 years and those aged 65 years or older. Marginal reductions were seen among adolescents. States that have not passed strict texting bans should consider doing so.

Fractures and mortality in relation to different osteoporosis treatments.

OBJECTIVES: Few studies have assessed the effectiveness of different drugs for osteoporosis (OP). We aimed to determine if fracture and mortality rates vary among patients initiating different OP medications. METHODS: We used the Medicare 5% sample to identify new users of intravenous (IV) zoledronic acid (n=1.674), oral bisphosphonates (n=32.626), IV ibandronate (n=492), calcitonin (n=2.606), raloxifene (n=1.950), or parathyroid hormone (n=549). We included beneficiaries who were ≥65 years of age, were continuously enrolled in fee-for-service Medicare and initiated therapy during 2007-2009. Outcomes were hip fracture, clinical vertebral fracture, and all-cause mortality, identified using inpatient and physician diagnosis codes for fracture, procedure codes for fracture repair, and vital status information. Cox regression models compared users of each medication to users of IV zoledronic acid, adjusting for multiple confounders. RESULTS: During follow-up (median, 0.8-1.5 years depending on the drug), 787 subjects had hip fractures, 986 had clinical vertebral fractures, and 2.999 died. Positive associations included IV ibandronate with hip fracture (adjusted hazard ratio (HR), 2.37; 95% confidence interval (CI) 1.25-4.51), calcitonin with vertebral fracture (HR=1.59, 95%CI 1.04-2.43), and calcitonin with mortality (HR=1.31; 95%CI 1.02-1.68). Adjusted HRs for other drug-outcome comparisons were not statistically significant. CONCLUSIONS: IV ibandronate and calcitonin were associated with higher rates of some types of fracture when compared to IV zolendronic acid. The relatively high mortality associated with use of calcitonin may reflect the poorer health of users of this agent.

Impact of texting laws on motor vehicular fatalities in the United States.

Using a panel study design, we examined the effects of different types of texting bans on motor vehicular fatalities. We used the Fatality Analysis Reporting System and a difference-in-differences approach to examine the incidence of fatal crashes in 2000 through 2010 in 48 US states with and without texting bans. Age cohorts were constructed to examine the impact of these bans on age-specific traffic fatalities. Primarily enforced laws banning all drivers from texting were significantly associated with a 3% reduction in traffic fatalities in all age groups, and those banning only young drivers from texting had the greatest impact on reducing deaths among those aged 15 to 21 years. Secondarily enforced restrictions were not associated with traffic fatality reductions in any of our analyses.

Patterns and predictors of osteoporosis medication discontinuation and switching among Medicare beneficiaries.

BACKGROUND: Low adherence to bisphosphonate therapy is associated with increased fracture risk. Factors associated with discontinuation of osteoporosis medications have not been studied in-depth. This study assessed medication discontinuation and switching patterns among Medicare beneficiaries who were new users of bisphosphonates and evaluated factors possibly associated with discontinuation. METHODS: We identified patients initiating bisphosphonate treatment using a 5% random sample of Medicare beneficiaries with at least 24 months of traditional fee-for-service and part D drug coverage from 2006 through 2009. We classified medication status at the end of follow-up as: continued original bisphosphonate, discontinued without switching or restarting, restarted the same drug after a treatment gap (≥ 90 days), or switched to another anti-osteoporosis medication. We conducted logistic regression analyses to identify baseline characteristics associated with discontinuation and a case-crossover analysis to identify factors that precipitate discontinuation. RESULTS: Of 21,452 new users followed respectively for 12 months, 44% continued their original therapy, 36% discontinued without switching or restarting, 8% restarted the same drug after a gap greater than 90 days, and 11% switched to another anti-osteoporosis medication. Factors assessed during the 12-month period before initiation were weakly associated with discontinuation. Several Factors measured during follow-up were associated with discontinuation, including more physician visits, hospitalization, having a dual-energy X-ray absorptiometry test, higher Charlson comorbidity index scores, higher out-of-pocket drug payments, and upper gastrointestinal problems. Patterns were similar for 4,738 new users followed for 30 months. CONCLUSIONS: Among new bisphosphonates users, switching within and across drug classes and extended treatment gaps are common. Robust definitions and time-varying considerations should be considered to characterize medication discontinuation more accurately.

Generic alendronate use among Medicare beneficiaries: are Part D data complete?

BACKGROUND: Generic alendronate was approved in the United States on February 6, 2008. Medicare beneficiaries might pay for generic alendronate out-of-pocket without having claims submitted, resulting in misclassification of generic alendronate use in Medicare data. OBJECTIVES: To estimate the completeness of generic alendronate use in 2008 Medicare Part D data; to identify factors associated with staying on branded alendronate versus switching to a generic product. METHODS: We identified Medicare beneficiaries highly adherent (medication possession ratio ≥80%) with branded alendronate during 1/1/06-2/6/07 ("2007 cohort") and during 1/1/07-2/6/08 ("2008 cohort"). The outcome was medication status at the end of follow-up (12/31/2007 or 12/31/2008), classified as continued branded alendronate, switched to generic alendronate, switched to another bisphosphonate or presumed discontinued bisphosphonate therapy. Cox regression estimated the hazard ratio (HR) for discontinuation in 2008 compared to 2007. Multinomial logistic regression identified factors associated with medication status for the 2008 cohort. RESULTS: Among 15,310 subjects using branded alendronate in the 2008 cohort, 81% switched to generic alendronate. The proportion presumably discontinuing bisphosphonate therapy was 8.9% in 2008 compared to 7.7% in the 2007 cohort (adjusted HR, 1.15; 95% confidence interval, 1.05, 1.26). Factors associated with staying on branded alendronate in 2008 were higher income, eligibility for a low income subsidy and use of Fosamax® plus vitamin D. CONCLUSION: Evaluation of Medicare prescription drug data suggests that the amount of missing claims for generic alendronate in 2008 was not substantial, and misclassification of exposure in studies examining alendronate use post-generic product availability should be minimal.

Dental hygienists' scope of practice regulations and preventable non-traumatic dental emergency department visits: A cross-sectional study of 10 U.S. states.

OBJECTIVES: As emergency department (ED) visits for non-traumatic dental complaints continue to rise in the United States (U.S.), some states are implementing initiatives to expand access to the oral health workforce. This study examines the associations between the 2014 Dental Hygiene Professional Practice Index (DHPPI) and preventable dental ED visits. METHODS: In 2020, we used ED data from 10 U.S. states and ordinary least squares models to examine the relationship between the states' DHPPI scores and preventable dental ED use. We stratified regressions by age to examine this relationship across different age cohorts and introduced interaction terms to assess the same relationship among rural and urban residents. RESULTS: On average, 23.8% of all non-traumatic dental ED visits were identified as preventable. Controlling for other factors, a one-point increase in DHPPI scores was associated with a decrease of 0.01 (95% CI -0.03, -0.02) preventable dental ED visits per 1000 county population in each year-quarter. In the age-stratified models, the strength of the association between DHPPI scores and preventable dental ED visits was higher in the 20 to 34 (-0.03, 95% CI -0.04, -0.02), and the 35 to 50 age cohorts (-0.17, 95% CI -0.00, -0.00). U.S. states with DHPPI scores below 60 saw significantly higher preventable dental ED visits among rural residents. CONCLUSIONS: This study demonstrates that stringent state policies regarding the dental hygienist workforce are associated with higher preventable dental ED visits in the U.S. Policy makers and stake holders must address the scope of practice policies to alleviate the burden of access to oral healthcare.

Social determinants of health and emergency department utilization in Alabama Children's Health Insurance Program.

OBJECTIVES: Injuries are the leading cause of death among children and youth in the United States, representing a major concern to society and to the public and private health plans covering pediatric patients. Data from ALL Kids, Alabama's Children's Health Insurance Program, were used to evaluate the relationship between community-level social determinants of health (SDOH) and pediatric emergency department (ED) use and differences in these associations by age and race. STUDY DESIGN: This was a retrospective, pooled cross-sectional analysis. METHODS: We used ALL Kids data to identify ED visits (injury and all-cause) among children who were enrolled at any time from 2015 to 2017. Exploratory factor analysis was used to categorize SDOH from 18 selected Census tract-level variables. Multilevel Poisson regression models were used to evaluate the effects of community and individual factors and their interactions. RESULTS: Census tract-level SDOH were grouped as low socioeconomic status (SES), urbanicity, and immigrant-density factors. Low SES and urbanicity factors were associated with ED visits (injury and all-cause). The low SES and urbanicity factors also moderated the association between race and ED visits (injury and all-cause). CONCLUSIONS: The environment in which children live influences their ED use; however, the impact varies by age, race, and Census tract factors. Further studies should focus on specific community factors to better understand the relationship among SDOH, individual characteristics, and ED utilization.

Mortality following bone metastasis and skeletal-related events among women with breast cancer: a population-based analysis of U.S. Medicare beneficiaries, 1999-2006.

The aim of the study is to quantify the impact of bone metastasis and skeletal-related events (SREs) on mortality in older breast cancer patients. Using the linked Surveillance, Epidemiology and End Results-Medicare database, we identified women aged 65 years or older diagnosed with breast cancer between July 1, 1999 and December 31, 2005 and followed them to determine deaths occurring through December 31, 2006. We classified patients as having possible bone metastasis and SREs using discharge diagnoses from inpatient claims and diagnoses paired with procedure codes from outpatient claims. We used Cox regression to estimate mortality hazards ratios (HR) among women with bone metastasis with or without SRE, compared with women without bone metastasis. Among 98,260 women with breast cancer (median follow-up, 3.3 years), 7,189 (7.3%) had bone metastasis either at breast cancer diagnosis (1.5%) or during follow-up (5.8%). SREs occurred in 3,319 (46%) of women with bone metastasis. HRs for risk of death were 4.9 (95% CI 4.7-5.1) and 6.2 (95% CI 5.9-6.5), respectively, for women with bone metastasis but no SRE and for women with bone metastasis plus SRE, compared with women without bone metastasis. In analyses restricted to women with bone metastasis, the adjusted HR was 1.5 (95% CI 1.4-1.6) for women with bone metastasis plus SRE, compared with women with bone metastasis but without SRE. Having a bone metastasis, as indicated by Medicare claims, was associated strongly with mortality among women with breast cancer. This association was stronger for bone metastasis complicated by SRE than for bone metastasis without SRE.

Disparities in Telehealth Utilization in a Population of Publicly Insured Children During the COVID-19 Pandemic.

Telehealth became a crucial vehicle for health care delivery in the United States during the COVID-19 pandemic. However, little research exists on inequities in telehealth utilization among the pediatric population. This study examines disparities in telehealth utilization in a population of publicly insured children. This observational, retrospective study used administrative data from Alabama's stand-alone Children's Health Insurance Program, ALL Kids. Rates of any telehealth use for March to December 2020 were examined. In addition-to capture lack of health care utilization-rates of having no medical claims were examined and compared with March to December 2019 and 2018. Multinomial logit models were estimated to investigate how telehealth use and having no medical claims (reference category: having medical claims but no telehealth) were associated with race/ethnicity, rural-urban residence, and family income. Of the 106,478 enrollees over March to December 2020, 13.4% had any telehealth use and 24.7% had no medical claims. The latter was greater than no medical claims in 2019 (19.5%) and 2018 (20.7%). Black and Hispanic children had lower odds of any telehealth use (odds ratio [OR]: 0.81, P < 0.01; OR: 0.68, P < 0.01) and higher odds of no medical claims (OR: 1.11, P < 0.05; OR: 1.73, P < 0.05) than non-Hispanic White children. Rural residents had lower odds of telehealth use than urban residents. Those in the highest family income-based fee group had higher odds of telehealth use than the lowest family income-based fee group. As telehealth will likely continue to play an important role in health care delivery, additional efforts/investments are required to ensure telehealth does not further exacerbate inequities in pediatric health care access.

Medical liability and health care reform.

We examine the impact of the Affordable Care Act (ACA) on medical liability and the controversy over whether federal medical reform including a damages cap could make a useful contribution to health care reform. By providing guaranteed access to health care insurance at community rates, the ACA could reduce the problem of under-compensation resulting from damages caps. However, it may also exacerbate the problem of under-claiming in the malpractice system, thereby reducing incentives to invest in loss prevention activities. Shifting losses from liability insurers to health insurers could further undermine the already weak deterrent effect of the medical liability system. Republicans in Congress and physician groups both pushed for the adoption of a federal damages cap as part of health care reform. Physician support for damages caps could be explained by concerns about the insurance cycle and the consequent instability of the market. Our own study presented here suggests that there is greater insurance market stability in states with caps on non-economic damages. Republicans in Congress argued that the enactment of damages caps would reduce aggregate health care costs. The Congressional Budget Office included savings from reduced health care utilization in its estimates of cost savings that would result from the enactment of a federal damages cap. But notwithstanding recent opinions offered by the CBO, it is not clear that caps will significantly reduce health care costs or that any savings will be passed on to consumers. The ACA included funding for state level demonstration projects for promising reforms such as offer and disclosure and health courts, but at this time the benefits of these reforms are also uncertain. There is a need for further studies on these issues.
