Service provision and quality outcomes in home health for rural Medicare beneficiaries at high risk for unplanned care

Multiple barriers exist to providing home health care in rural areas. This study examined relationships between service provision and quality outcomes among rural, fee-for-service Medicare beneficiaries who received home health care between 2011 and 2013 for conditions associated with high-risk for unplanned care. More skilled nursing visits, visits by more types of providers, more timely care, and shorter lengths of stay were associated with significantly higher odds of hospital readmission and emergency department use and significantly lower odds of community discharge. Results may indicate unmeasured clinical severity and care needs among this population. Additional research regarding the accuracy of current severity measures and adequacy of case-mix adjustment for quality metrics is warranted, especially given the continued focus on value-based payment policies.     

Rethinking prevention in primary care: applying the chronic care model to address health risk behaviors

This study examines the Chronic Care Model (CCM) as a framework for preventing health risk behaviors such as tobacco use, risky drinking, unhealthy dietary patterns, and physical inactivity. Data were obtained from primary care practices participating in a national health promotion initiative sponsored by the Robert Wood Johnson Foundation. Practices owned by a hospital health system and exhibiting a culture of quality improvement were more likely to offer recommended services such as health risk assessment, behavioral counseling, and referral to community-based programs. Practices that had a multispecialty physician staff and staff dieticians, decision support in the form of point-of-care reminders and clinical staff meetings, and clinical information systems such as electronic medical records were also more likely to offer recommended services. Adaptation of the CCM for preventive purposes may offer a useful framework for addressing important health risk behaviors.     

Cost-sharing for emergency care and unfavorable clinical events: findings from the safety and financial ramifications of ED copayments study

Objective. To evaluate the effect of emergency department (ED) copayment levels on ED use and unfavorable clinical events. Data Source/Study Setting. Kaiser Permanente–Northern California (KPNC), a prepaid integrated delivery system. Study Design. In a quasi‐experimental longitudinal study with concurrent controls, we estimated rates of ED visits, hospitalizations, ICU admissions, and deaths associated with higher ED copayments relative to no copayment, using Poisson random effects and proportional hazard models, controlling for patient characteristics. The study period began in January 1999; more than half of the population experienced an employer‐chosen increase in their ED copayment in January 2000. Data Collection/Extraction Methods. Using KPNC automated databases, the 2000 U.S. Census, and California state death certificates, we collected data on ED visits and unfavorable clinical events over a 36‐month period (January 1999 through December 2001) among 2,257,445 commercially insured and 261,091 Medicare insured health system members. Principal Findings. Among commercially insured subjects, ED visits decreased 12 percent with the $20–35 copayment (95 percent confidence interval [CI]: 11–13 percent), and 23 percent with the $50–100 copayment (95 percent CI: 23–24 percent) compared with no copayment. Hospitalizations, ICU admissions, and deaths did not increase with copayments. Hospitalizations decreased 4 percent (95 percent CI: 2–6 percent) and 10 percent (95 percent CI: 7–13 percent) with ED copayments of $20–35 and $50–100, respectively, compared with no copayment. Among Medicare subjects, ED visits decreased by 4 percent (95 percent CI: 3–6 percent) with the $20–50 copayments compared with no copayment; unfavorable clinical events did not increase with copayments, e.g., hospitalizations were unchanged (95 percent CI: ?3 percent to +2 percent) with $20–50 ED copayments compared with no copayment. Conclusions. Relatively modest levels of patient cost‐sharing for ED care decreased ED visit rates without increasing the rate of unfavorable clinical events.     

Effects of the Premier Hospital Quality Incentive Demonstration on Medicare Patient Mortality and Cost

Objective. To evaluate the effects of the Premier Inc. and Centers for Medicare and Medicaid Services Hospital Quality Incentive Demonstration (PHQID), a public quality reporting and pay-for-performance (P4P) program, on Medicare patient mortality, cost, and outlier classification.
Data Sources. The 2000–2006 Medicare inpatient claims, Medicare denominator files, and Medicare Provider of Service files.
Study Design. Panel data econometric methods are applied to a retrospective cohort of 11,232,452 admissions from 6,713,928 patients with principal diagnoses of acute myocardial infarction (AMI), heart failure, pneumonia, or a coronary-artery bypass grafting (CABG) procedure from 3,570 acute care hospitals between 2000 and 2006. Three estimators are used to evaluate the effects of the PHQID on risk-adjusted (RA) mortality, cost, and outlier classification in the presence of unobserved selection, resulting from the PHQID being voluntary: fixed effects (FE), FE estimated in the subset of hospitals eligible for the PHQID, and difference-in-difference-in-differences.
Data Extraction Methods. Data were obtained from CMS.
Principal Findings. This analysis found no evidence that the PHQID had a significant effect on RA 30-day mortality or RA 60-day cost for AMI, heart failure, pneumonia, or CABG and weak evidence that the PHQID increased RA outlier classification for heart failure and pneumonia.
Conclusions. By not reducing mortality or cost growth, this study suggests that the PHQID has made little impact on the value of inpatient care purchased by Medicare.     

Payment systems and incentives in primary care: implications of recent reforms in Estonia and Romania

Since the early 1990s, major reform in healthcare has been adopted in former communist countries in Central and Eastern Europe. More than 20 years after, reform in healthcare still draws much interest from policy makers and academics alike. One of the dynamic components of reform has been the reform of payment systems in primary care. This article looks at recent developments in payment systems and financial incentives in Estonia and Romania. We conclude that finding the appropriate mix in paying and incentivizing primary care providers in a transitional context is no easy solution for healthcare policy makers who need to carefully weigh in the advantages and inherent problems of various payment arrangements. In a transitional, rapidly changing healthcare system and society, and a context of financial stringency, the theoretical effects of payment mechanisms may be more difficult to predict and manage than it is expected.

Practice‐site‐level measures of primary care comprehensiveness and their associations with patient outcomes

ObjectivesTo develop two practice‐site‐level measures of comprehensiveness and examine their associations with patient outcomes, and how their performance differs from physician‐level measures.Data SourcesMedicare fee‐for‐service claims.Study DesignWe calculated practice‐site‐level comprehensiveness measures (new problem management and involvement in patient conditions) across 5286 primary care physicians (PCPs) at 1339 practices in the Comprehensive Primary Care initiative evaluation in 2013. We assessed their associations with practices’ attributed beneficiaries’ 2014 total Medicare expenditures, hospitalization rates, ED visit rates. We also examined variation in PCPs’ comprehensiveness across PCPs within practices versus between primary care practices. Finally, we compared associations of practice‐site and PCP‐level measures with outcomes.Principal FindingsThe measures had good variation across primary care practices, strong validity, and high reliability. Receiving primary care from a practice at the 75th versus 25th percentile on the involvement in patient conditions measure was associated with $21.93 (2.8%) lower total Medicare expenditures per beneficiary per month (P < .01). Receiving primary care from a practice at the 75th versus 25th percentile on the new problem management measure was associated with $14.77 (1.9%) lower total Medicare expenditures per beneficiary per month (P < .05); 8.84 (3.0%) fewer hospitalizations (P < .001), and 21.27 (3.1%) fewer ED visits per thousand beneficiaries per year (P < .01). PCP comprehensiveness varied more within than between practices.ConclusionsMore comprehensive primary care practices had lower Medicare FFS expenditures, hospitalization, and ED visit rates. Both PCP and practice‐site level comprehensiveness measures had strong construct and predictive validity; PCP‐level measures were more precise.     

Inappropriate use of emergency ambulance services and the implications for primary health care in Japan

The number and per-capita emergency transports by public ambulancesand the percentage of transports of patients with non-emergencyconditions has been increasing in Japan, especially in urbanareas. Public ambulance services are, of course, essential fortransporting patients with crucial health problems. However,inappropriate ambulance use by patients who do not need emergencytreatment, but who need primary health care, means that thesepatients cannot get suitable health care, and diminishes theeffectiveness and efficiency of emergency medical-care servicesystems. The purposes of this study were to identify the factorsrelating to usage of public ambulance services in urban areas,to determine how to make these services more effective and moreefficient, and to discuss how to provide primary health-careservices so as to reduce the inappropriate use of public ambulanceservices. We investigated the accessibility of primary health-careservices, the characteristics of public ambulance service utilization,and the potential needs of the elderly for emergency-care servicesin two Tokyo wards: Edogawa andSetagaya. There were less healthresources, such as clinics, hospital beds and physicians, percapita in Edogawa than in Setagaya. Both the percentage of ambulancetransports of patients suffering from mild problems and thepercentage of ambulance transports on Sundays were higher inEdogawa than in Setagaya. Our survey showed that the percentagesof the elderly who would call for ambulances for each of threespecific health problems (fever, chest pain and ankle sprain)were all higher in Edogawa than in Setagaya. In both wards,elderly people living with their children and/or grandchildrenwere more likely to choose different health resources accordingto the specific problem being experienced than were elderlypeople living with other aged persons but without young people.The insufficient development of primary healthcare resourcesand systems increased the inappropriate use of high-cost emergencyambulance services by the elderly living in urban areas, wherefamily support is weakening. Health systems therefore need tobe reoriented so as to enhance accessibility to primary healthcareservices.     

The impact of Medicaid expansion on spending and utilization by older low-income Medicare beneficiaries

Objective

To examine indirect spillover effects of Affordable Care Act (ACA) Medicaid expansions to working-age adults on health care coverage, spending, and utilization by older low-income Medicare beneficiaries.

Data Sources

2010–2018 Health and Retirement Study survey data linked to annual Medicare beneficiary summary files.

Study Design

We estimated individual-level difference-in-differences models of total spending for inpatient, institutional outpatient, physician/professional provider services; inpatient stays, outpatient visits, physician visits; and Medicaid and Part A and B Medicare coverage. We compared changes in outcomes before and after Medicaid expansion in expansion versus nonexpansion states.

Data Collection/Extraction Methods

The sample included low-income respondents aged 69 and older with linked Medicare data, enrolled in full-year traditional Medicare, and residing in the community.

Principal Findings

ACA Medicaid expansion was associated with a 9.8 percentage point increase in Medicaid coverage (95% CI: 0.020–0.176), a 4.4 percentage point increase in having any institutional outpatient spending (95% CI: 0.005–0.083), and a positive but statistically insignificant 2.4 percentage point change in Part B enrollment (95% CI: −0.003 to 0.050, p = 0.079).

Conclusions

ACA Medicaid expansion was associated with more institutional outpatient spending among older low-income Medicare beneficiaries. Increased care costs should be weighed against potential benefits from increased realized access to care.     

Differences in patient perceptions of integrated care among black,hispanic, and white Medicare beneficiaries

ObjectiveThis study sought to identify potential disparities among racial/ethnic groups in patient perceptions of integrated care (PPIC) and to explore how methodological differences may influence measured disparities.Data SourceData from Medicare beneficiaries who completed the 2015 Medicare Current Beneficiary Survey (MCBS) and were enrolled in Part A benefits for an entire year.Study DesignWe used 4‐point measures of eight dimensions of PPIC and assessed differences in dimensions among racial/ethnic groups. To estimate differences, we applied a “rank and replace” method using multiple regression models in three steps, balancing differences in health status among racial groups and adjusting for differences in socioeconomic status. We reran all analyses with additional SES controls and using standard multiple variable regression.Data Collection/Extraction MethodsNot applicable.Principal FindingsWe found several significant differences in perceived integrated care between Black versus White (three of eight measures) and Hispanic versus White (one of eight) Medicare beneficiaries. On average, Black beneficiaries perceived more integrated support for self‐care than did White beneficiaries (mean difference = 0.14, SE = 0.06, P =.02). Black beneficiaries perceived more integrated specialists’ knowledge of past medical history than did White beneficiaries (mean difference = 0.12, SE = 0.06, P =.01). Black and Hispanic beneficiaries also each reported, on average, 0.18 more integrated medication and home health management than did White beneficiaries (P <.01 and P <.01). These findings were robust to sensitivity analyses and model specifications.ConclusionsThere exist some aspects of care for which Black and Hispanic beneficiaries may perceive greater integrated care than non‐Hispanic White beneficiaries. Further studies should test theories explaining why racial/ethnic groups perceive differences in integrated care.     

Acceptance of New Medicaid Patients by Primary Care Physicians and Experiences with Physician Availability among Children on Medicaid or the Children's Health Insurance Program

Objective

To estimate the relationship between physicians'' acceptance of new Medicaid patients and access to health care.

Data Sources

The National Ambulatory Medical Care Survey (NAMCS) Electronic Health Records Survey and the National Health Interview Survey (NHIS) 2011/2012.

Study Design

Linear probability models estimated the relationship between measures of experiences with physician availability among children on Medicaid or the Children''s Health Insurance Program (CHIP) from the NHIS and state-level estimates of the percent of primary care physicians accepting new Medicaid patients from the NAMCS, controlling for other factors.

Principal Findings

Nearly 16 percent of children with a significant health condition or development delay had a doctor''s office or clinic indicate that the child''s health insurance was not accepted in states with less than 60 percent of physicians accepting new Medicaid patients, compared to less than 4 percent in states with at least 75 percent of physicians accepting new Medicaid patients. Adjusted estimates and estimates for other measures of access to care were similar.

Conclusions

Measures of experiences with physician availability for children on Medicaid/CHIP were generally good, though better in states where more primary care physicians accepted new Medicaid patients.
