More physicians: improved availability or induced demand?

A number of empirical studies have shown that there is a negative association between population:physician ratio and utilization of medical services. However, it is not clear whether this relationship reflects supplier-inducement, the effect of lower prices on patient demand, a supply response to variation in health status, or improved availability. In Norway, patient fees and state reimbursement fees are set centrally. Therefore, the correlation between utilization and population:physician ratio either reflects supplier-inducement, a supply response or an availability effect. We applied a theoretical model which distinguished between an inducement and an availability effect. The model was implemented on a cross-sectional data set which contained information about patient visits and laboratory tests for all fee-for-service primary care physicians in Norway. Since population:physician ratio is potentially endogenous, an instrumental variable approach is used. We found no evidence for inducement either for number of visits or for provision of laboratory services.

Fee-for-Service Medicare-Enrolled Elderly Veterans Are Increasingly Voting with Their Feet to Use More VA and Less Medicare, 2003-2014

OBJECTIVE

To examine the long-term reliance on outpatient care at the population (i.e., system) level among fee-for-service Medicare-enrolled elderly veterans in the Department of Veterans Affairs (VA) health care system and Medicare from 2003 to 2014.

DATA SOURCES/STUDY SETTING

We analyzed a 5 percent random sample, stratified by facility, age, gender, and race, of Medicare-enrolled veterans enrolled in a VA primary care panel using VA administrative data and Medicare claims.

STUDY DESIGN

We performed a repeated cross-sectional analysis over 48 quarters. VA reliance was defined at the system level as the proportion of total visits (VA + Medicare) that occurred in VA. We examined four visit types and seven high-volume medical subspecialties. We applied direct standardization adjusting for age, gender, and race using the 2010 population distribution of Medicare-enrolled veterans.

PRINCIPAL FINDINGS

Over the 12-year period, VA provided the vast majority of mental health care. Conversely, veterans received slightly more than half of their primary care and most of their specialty care, surgical care, and seven high-volume medical subspecialties through Medicare. However, reliance on VA outpatient care steadily increased over time for all categories of care.

CONCLUSIONS

Despite the controversies about VA access to care, Medicare-enrolled veterans, who have a choice of using VA or Medicare providers, appear to increase their use of VA care prior to the Choice Act.

Assessing the culture of medical group practices

This study was designed to identify the relevant components of the organizational culture of medical group practices and to develop an instrument to measure those cultures. Building on the work of industrial psychologists and organizational sociologists, a 35-item instrument was developed through an iterative process with more than 100 medical groups. The final instrument was tested using responses from physicians practicing in two very different medical groups: one a prepaid group practice with salaried physicians and the other, until recently, a fee-for-service practice. Using stepwise discriminant analysis of the responses to this instrument, more than 90% of the physicians were able to be placed in the appropriate practice setting.

Link between pay for performance incentives and physician payment mechanisms: evidence from the diabetes management incentive in Ontario

Pay for performance (P4P) incentives for physicians are generally designed as additional payments that can be paired with any existing payment mechanism such as a salary, fee-for-services and capitation. However, the link between the physician response to performance incentives and the existing payment mechanisms is still not well understood. In this article, we study this link using the recent primary care physician payment reform in Ontario as a natural experiment and the Diabetes Management Incentive as a case study. Using a comprehensive administrative data strategy and a difference-in-differences matching strategy, we find that physicians in a blended capitation model are more responsive to the Diabetes Management Incentive than physicians in an enhanced fee-for-service model. We show that this result implies that the optimal size of P4P incentives vary negatively with the degree of supply-side cost-sharing. These results have important implications for the design of P4P programs and the cost of their implementation.

Provider choice and continuity for the treatment of depression

The role of specialist versus generalist providers regularly surfaces in health-care reform debates about costs and quality of care. By changing incentives to seek and deliver care, different payments systems can affect both the probability of initial specialty care and the duration of this patient-provider relationship. The authors compare provider selection (psychiatrist, nonphysician mental-health specialist, general medical provider) and duration of this relationship among depressed patients in prepaid and fee-for-service plans. Regarding initial care, depressed patients in prepaid plans are significantly less likely to see a psychiatrist and more likely to see a nonphysician mental-health specialist than patients in fee-for-service plans. Although the mix of providers differs, patient demographic and clinical characteristics have similar effects on specialty in both payment systems, ie, there are no differences in who gets specialty care by type of payment, but in how many get specialty care. The average duration of a patient-provider relationship is significantly shorter in prepaid plans. Durations are significantly shorter for patients of both psychiatrists and general medical providers in prepaid plans, but do not differ by payments type for nonphysician therapists. In both payments systems, patients of nonphysician providers end the relationship sooner than patients of psychiatrists or general medical providers. Although the authors find provider switching to be associated significantly with discontinuing antidepressant medication, there is no significant direct effect on patient health outcomes.

Low-Value Service Use in Provider Organizations

OBJECTIVE

To assess whether provider organizations exhibit distinct profiles of low-value service provision.

DATA SOURCES

2007-2011 Medicare fee-for-service claims and enrollment data.

STUDY DESIGN

Use of 31 services that provide minimal clinical benefit was measured for 4,039,733 beneficiaries served by 3,137 provider organizations. Variation across organizations, persistence within organizations over time, and correlations in use of different types of low-value services within organizations were estimated via multilevel modeling, with adjustment for beneficiary sociodemographic and clinical characteristics.

PRINCIPAL FINDINGS

Organizations provided 45.6 low-value services per 100 beneficiaries on average, with considerable variation across organizations (90th/10th percentile ratio, 1.78; 95 percent CI, 1.72-1.84), including substantial between-organization variation within hospital referral regions (90th/10th percentile ratio, 1.66; 95 percent CI, 1.60-1.71). Low-value service use within organizations was highly correlated over time (r, 0.98; 95 percent CI, 0.97-0.99) and positively correlated between 13 of 15 pairs of service categories (average r, 0.26; 95 percent CI, 0.24-0.28), with the greatest correlation between low-value imaging and low-value cardiovascular testing and procedures (r, 0.54).

CONCLUSIONS

Use of low-value services in provider organizations exhibited substantial variation, high persistence, and modest consistency across service types. These findings are consistent with organizations shaping the practice patterns of affiliated physicians.

Survival and treatment for colorectal cancer Medicare patients in two group/staff health maintenance organizations and the fee-for-service setting

The current study compares treatment use and long-term survival in colorectal cancer patients between Medicare beneficiaries enrolled in two large prepaid group/staff health maintenance organizations (HMOs) and the fee-for-service (FFS) setting. The study is based on 15,352 colorectal cancer cases diagnosed between 1985 and 1992 and followed through 1995. Survival differences between the HMO and FFS cases were assessed using Cox regression. Treatment differences were evaluated using logistic regression. HMO cases had a lower overall mortality than did FFS cases but not a significantly lower colorectal cancer-specific mortality. Use of surgical resection was similar between HMO and FFS cases. However, rectal cancer cases in the HMOs were more likely to receive postsurgical radiation therapy than FFS cases. Superior overall survival in the HMOs may be the result of increased colorectal cancer screening, greater use of adjuvant therapies, and selection of healthier individuals.

Effects of Medicaid managed care on health care use: infant emergency department and ambulatory services

OBJECTIVE

Many urban children rely on emergency departments (ED) for ambulatory care. The objective of this study was to determine whether enrollment in Medicaid managed care (MMC) alters ED or other ambulatory care compared with fee-for-service Medicaid (FFSM).

METHODS

A prospective cohort study of infants born between May 1994 and April 1995 with a 6-month follow-up period was conducted in an urban, teaching hospital and surrounding ambulatory settings. A consecutive sample of 644 infants enrolled in MMC or FFSM was studied; 92% of eligible patients were enrolled, and 94% completed follow-up. The main outcome measures were 1) proportion of patients in each group visiting an ED, primary care practitioner (PCP), or specialist; 2) mean number of visits per group; and 3) ED reliance (EDR) defined as the proportion of all ambulatory visits occurring in an ED.

RESULTS

Fifty-six percent of MMC and 54% of FFSM patients visited an ED (relative risk: 1.03; 95% confidence interval [CI]: 0.83, 1.27). More MMC patients had a sick visit to their PCP (relative risk: 1.34; 95% CI: 1.03, 1.74); no difference in proportion with well-child or specialty visits was found. Although the mean number of total ambulatory, ED, and specialty visits was the same, MMC patients had fewer well-child and more sick visits to the PCP than FFSM patients (P =.01). EDR was 21% for both groups (P =.95). After adjustment for other factors in multivariate analysis, insurance status remained unassociated with EDR (adjusted odds ratio [OR]: 0.91; 95% CI: 0.56, 1.69). Factors associated with EDR included United States-born mother (OR: 5.34; 95% CI: 1.61, 17.68) and use of a hospital-based primary care physician (OR: 2.00; 95% CI: 1.34, 2.98). Variables that characterized infants who were less likely to be ED reliant included adequate maternal prenatal care (OR: 0.52; 95% CI: 0.34, 0.78) and having a mother who completed high school (OR: 0.67; 95% CI: 0.45, 0.99).

CONCLUSIONS

Enrollment in MMC did not alter ED usage patterns when compared with FFSM. Some variation in use of other ambulatory services was detected.

Do Medicare HMOs still reduce health services use after controlling for selection bias?

This study models the relationship between Medicare beneficiary decisions to join Medicare HMOs and subsequent health services utilization. The relationship between health plan choice and utilization is thought to be endogenous because of favorable selection into HMOs. Previous studies found significantly lower inpatient utilization among Medicare HMO enrollees than among nonenrollees, but lacked strong controls for selection bias. Thus, a firm conclusion could not be drawn as to whether the observed differences were attributable to the HMO practice setting or to baseline differences in the illness profiles of the two groups studied. The present study uses simultaneous equations methods, including discrete factor estimation, to test the effect of Medicare HMOs on utilization when strong controls for selection bias are imposed. The model was run on a panel of 1993-1996 data from the Medicare Current Beneficiary Survey, supplemented with linked data on Medicare HMO characteristics and area supply characteristics. The study found that even when favorable selection is controlled for, Medicare HMOs significantly reduce both the probability of hospitalization and the number of inpatient days used by those who are hospitalized. Medicare HMOs do not, however, appear to reduce the use of physician services.

Effect of utilization review in a fee-for-service health insurance plan

BACKGROUND

Although utilization review is widely used to control health care costs, its effect on patterns of health care is uncertain.

METHODS

In 1989, New York City and its unions temporarily replaced actual utilization review with sham review for half the participants in the city's fee-for-service health insurance plan. We compared the health services provided to 3702 enrollees whose requests were subjected to utilization review (the review group) with the services provided to 3743 enrollees whose requests received sham review and were automatically approved for insurance coverage (the nonreview group). The enrollees, physicians, and hospitals were all unaware of the group assignments.

RESULTS

During the study period (mean duration, eight months), the members of the review group underwent 1255 procedures in 20 categories of procedures for which second opinions were required (such as breast, cataract, foot, hernia, and hip-replacement surgery, as well as hysterectomy and coronary bypass surgery), and the members of the nonreview group underwent 1365 procedures (P = 0.02). The members of the review group had 124 fewer procedures in doctors' offices and hospital outpatient departments (P = 0.002). In the following year, the members of the review group underwent 248 procedures from the 20 categories, and the members of the nonreview group underwent 234 (P = 0.46). No other differences in patterns of care were found between the groups, including rates of hospital admission to medical-surgical, substances-abuse, or psychiatric units; average lengths of hospital stay; the percentage of enrollees who received preadmission testing; or rates of use of home care. During the study period, the mean age-adjusted insurance payments per person were $7,355 in the review group and $6,858 in the nonreview group (P = 0.06).

CONCLUSIONS

The utilization-review program reduced the performance of diagnostic and surgical procedures for which second opinions were required and did not merely delay them until the following year. Otherwise, the program had little effect. Alternatively, actual review and sham review may both have decreased the use of hospital services, with patients or their physicians choosing more efficient treatment when they believed that care would be reviewed.

Specialty care by child neurologists: a workforce analysis

OBJECTIVE

To provide a current profile of the practice of child neurology, report the attitudes of child neurologists toward practice, and analyze the supply of child neurologists.

METHODS

In March 2002, a questionnaire was sent to all active members of the Child Neurology Society (n = 1,051) and to nonmember physicians under age 70 who listed child neurology as a primary or secondary specialty on the American Medical Association Masterfile (n = 433). The response rate was 65%. Eligibility criteria were then applied to arrive at the sample of main specialty in child neurology working at least 20 hours per week in patient care. The final population was 604. Differences in practice characteristics were tested by practice type, and the number of full-time patient care child neurologists was projected by extrapolating to nonrespondents.

RESULTS

There are 904 full-time patient care child neurologists in the United States and 1.27 per 100,000 children. Career satisfaction is 90%, yet no growth in the supply is projected over the next 20 years. Wait times for an appointment average 53 and 44 days for a new and return visit, with longer wait times in university settings. Average annual income is 151,000 dollars.

CONCLUSION

The practice characteristics of child neurologists suggest that the specialty will be challenged to meet patient demands.

Receipt of preventive services among privately insured minorities in managed care versus fee-for-service insurance plans

OBJECTIVE

We compare preventive services utilization among privately insured African Americans and Hispanics in managed care organizations (MCOs) versus fee-for-service (FFS) plans. We also examine racial/ethnic disparities in the receipt of preventive services among enrollees in FFS or MCO plans.

DESIGN

Analysis of the nationally representative 1996 Medical Expenditure Panel Survey.

PARTICIPANTS

Participants included 1,120 Hispanic, 929 African-American, and 6,383 non-Hispanic white (NHW) adults age 18 to 64 years with private health insurance.

MEASUREMENTS AND MAIN RESULTS

We examined self-reported receipt of physical examination, blood pressure measurement, cholesterol assessment, Papanicolau testing, screening mammography, and breast and prostate examinations. Multivariate modeling was used to adjust for age, gender, education, household income, and health status. Hispanics in MCOs were more likely than their FFS counterparts to report having preventive services, with adjusted differences ranging from 5 to 19 percentage points (P <.05 for physical examination, blood pressure measurement, breast examination and Pap smear). Among African Americans, such patterns were of a smaller magnitude. In both MCOs and FFS plans the proportion of African Americans reporting preventive services was equal to or greater than NHWs. In contrast, among Hispanic women in FFS, a non-statistically significant trend of fewer cancer screening tests than NHW's was observed (Pap smears 75% vs 80%; mammograms 66% vs 74%, respectively). In both MCO and FFS plans, Hispanics were less likely than NHWs to report having blood pressure and cholesterol measurement (P <.05).

CONCLUSIONS

With the demise of traditional MCOs, reform efforts should incorporate those aspects of MCOs that were associated with greater preventive service utilization, particularly among Hispanics. Existing ethnic disparities warrant further attention.

Evaluation of claims, medical records, and self-report for measuring fecal occult blood testing among medicare enrollees in fee for service

BACKGROUND

There is no agreement on the best data source for measuring colorectal cancer (CRC) screening. Medicare claims have been used to measure CRC testing but the validity of using claims to measure fecal occult blood tests (FOBT) has not been established.

METHODS

We compared ascertainment of FOBT among three data sources: self-reports, Medicare claims, and medical records. Data were collected on FOBT use during the study window (1/1/1998 - 12/31/2002). Our study was conducted with North Carolina Medicare enrollees (N = 561) who had previously responded to a telephone survey on CRC tests. FOBT information was abstracted from respondents' physician office medical records and compared with self-reported FOBT use and Medicare claims for FOBT. Data sources were assessed for accuracy and completeness of FOBT reporting using sensitivity, specificity, positive predictive value, negative predictive value, and agreement.

RESULTS

Reporting of FOBT use in the prior year in medical records and Medicare claims agreed 82% of the time [95% confidence interval (95% CI), 79-85%]. FOBT 1-year use rates from self-report agreed with test use found in medical records 70% of the time (95% CI, 66-74%). The lowest agreement was between self-reported 1-year FOBT use and Medicare claims, which agreed 67% of the time (95% CI, 63-71%).

CONCLUSIONS

No data source could be established as providing complete and valid information about FOBT use among Medicare enrollees, showing the difficulty of ascertaining test use rates for noninvasive, low-cost procedures conducted in multiple settings. Caution should be used when attempting to measure FOBT use with self-report, Medicare claims, or medical records.

Effect of Physician Reimbursement Methodology on the Rate and Cost of Cataract Surgery

OBJECTIVES

To compare the effects of 2 reimbursement methodologies, fee-for-service and contact capitation, on cataract extraction rates and costs in a stable physician population with little potential for the influence of patient selection. Previous research evaluating the relationship between physician reimbursement incentives and cataract surgical rates has been limited by physician and patient selection bias.

METHODS

A pre-post analysis of claims and encounter data for an average of 91,473 commercial beneficiaries and 14,084 Medicare beneficiaries receiving eye care from a network of ophthalmologists and optometrists in St Louis, Mo, between 1997 and 1998. The rate of cataract extractions per 1000 beneficiaries, the costs of cataract procedures, the rates of noncataract procedures, and the level of professional reimbursement for providers were compared during the final 6 months of fee-for-service physician reimbursement and the first 6 months of contact capitation.

RESULTS

Both commercial and Medicare beneficiaries were approximately one half as likely to have cataract extraction (P<.001) under contact capitation as compared with fee-for-service. Professional reimbursement increased by 8% whereas facility fees for cataract procedures decreased by approximately 45%. Cataract surgical rates were disproportionately affected when compared with other ophthalmologic procedures. During the study period, cataract surgical rates were stable in the national and Missouri traditional fee-for-service Medicare population.

CONCLUSIONS

The stability of the physician and patient populations allowed us to isolate the effects of physician reimbursement methodology on practice patterns. Compared with fee-for-service, contact capitation reimbursement was associated with significant decreases in cataract extraction rates and costs. The frequency of the cataract extraction surgery, the most common major elective procedure in ophthalmology, was more responsive to physician financial incentives than other ophthalmologic procedures were.

Sensitivity of administrative claims to identify incident cases of lung cancer: a comparison of 3 health plans

BACKGROUND

Administrative claims are readily available, but their usefulness for identifying persons with non-small cell lung cancer (NSCLC) is relatively unknown, particularly for younger persons and those enrolled in Medicaid.

OBJECTIVES

To determine the sensitivity of ICD-9-CM codes for identifying persons with NSCLC.

METHODS

This was a retrospective analysis of insurance claims records linked to the Surveillance, Epidemiology, and End Results (SEER) cancer registry for the time period January 1, 2002, through December 31, 2005. Persons included in the sample were identified with NSCLC using SEER morphology and histology codes and were enrolled in a commercial health plan, Medicaid, or Medicare fee-for-service health plans in Washington State. The outcome measure was sensitivity, defined as the percentage of SEER-identified patients who were accurately identified as NSCLC cases using ICD-9-CM diagnoses (162.2, 162.3, 162.4, 162.5, 162.8, 162.9, or 231.2) recorded in any claim field in administrative claims data. We examined the influence of varying the number and timing of administrative codes in relation to the SEER cancer diagnosis date. In multivariate models, we examined the influence of age, sex, and comorbidity on sensitivity.

RESULTS

The sensitivity of 1 medical claim including at least 1 ICD-9-CM code for identifying NSCLC within 60 days of diagnosis as documented in the SEER registry was 51.1% for Medicaid, 87.7% for Medicare, and 99.4% for commercial plan members. Sensitivity can improve at the expense of identifying a portion of patients who are 3 or more months from their true diagnosis date. In multivariate models, age, race, and noncancer comorbidity but not gender significantly influenced sensitivity.

CONCLUSIONS

Administrative claims are sensitive for identifying patients with new NSCLC in the commercial and Medicare plans. For Medicaid patients, linkage with cancer registry records is needed to conduct studies using administrative claims.

Effectiveness of sealant treatment over five years in an insured population

BACKGROUND

The authors analyzed an insurance claim database to evaluate the use and effectiveness of placing sealants on first and second permanent molars of children in private dental practices.

METHODS

A retrospective study was conducted using an insured population with sealant coverage at 70 percent of the usual fee in a preferred provider organization than that limited reapplication to once every three years. Children were selected who were eligible for sealant benefits from July 1, 1990, to June 30, 1991. Two groups were selected for analysis, based on age, as determined by permanent molar eruption dates. Children who received sealants were compared with those who did not to determine post-sealant restorative outcomes after five years.

RESULTS

During the full year of coverage, sealants were used in only 16.3 percent of first permanent molars and 11.6 percent of second permanent molars. The five-year incidence of an occlusal restoration having been placed was 13.7 percent and 20.8 percent, respectively, on nonsealed first and second molars and 6.5 percent and 10.4 percent, respectively, on sealed first and second molars. From years three to five, sealant placement provided only nominal additional preventive effect.

CONCLUSIONS

In the population selected, both the incidence of occlusal caries and the use of sealants were lower than expected for both age groups. However, within these groups, molar occlusal surfaces were only half as likely to have been restored in sealed teeth than in nonsealed teeth after five years.

CLINICAL IMPLICATIONS

Based on the five-year data from a population with a low incidence of caries, the authors found that 15 sealed first permanent molars or 10 sealed second permanent molars prevented placement of one occlusal restoration. Therefore, sealants are more effective when placed in patients with risk factors for occlusal caries.

Breast cancer detection and outcomes in a disability beneficiary population

Women with disabilities may be at higher risk of late-stage breast cancer. Using the 1991-93 Medicare-Surveillance Epidemiology and End Results (SEER)-linked data set, the authors compared stage at diagnosis and mortality, for Social Security Disability Insurance (SSDI)-qualifying women and similarly aged non-SSDI qualifying women. Disabled patients were diagnosed at a later American Joint Committee on Cancer stage. Disabled patients had higher all-cause mortality rates but had similar breast cancer-specific mortality. Disabled women belonging to Medicare HMOs tended to have earlier stage diagnosis and better survival compared to Medicare fee-for-service (FFS) insurance. In conclusion, disabled patients tended to be diagnosed with breast cancer at a later stage and to have higher mortality. These findings were more pronounced in Medicare FFS than in Medicare HMOs.

The workforce in otolaryngology-head and neck surgery: moving into the next millennium

OBJECTIVE

The goal was to examine the current scope of otolaryngologists' practices, their geographic distribution, and the roles otolaryngologists and other specialists play in caring for patients with otolaryngic and related conditions of the head and neck.

STUDY DESIGN

A large national survey and administrative claims databases were examined to develop practice profiles and compile a physician supply for otolaryngology. A focus group of otolaryngologists provided information to model future scenarios.

RESULTS

The current and predicted workforce supply and demographics are at a satisfactory level and are decreasing as a proportion of the increasing population. Empiric data analysis supports the diverse nature of an otolaryngologist's practice and the unique role for otolaryngologists that is not shared by many other providers. Together with the focus group results, the study points to areas for which more background and training are warranted.

CONCLUSIONS

This study represents a first step in a process to form coherent workforce recommendations for the field of otolaryngology.

Women's use of preventive screening services: a comparison of HMO versus fee-for-service enrollees

Health maintenance organizations (HMOs) may relax some of the institutional barriers to using preventive screening services by requiring only a nominal copayment for such services and by promoting their use via educational programs. However, the gatekeeper system employed by HMOs may discourage the use of these services if referrals are required to access them. Using the 1987 National Medical Expenditure Survey and the 1992 National Health Interview Survey, the authors investigate whether HMO enrollment is associated with the use of preventive screening services for nonelderly, privately insured women. Employing models that control for self-selection into HMOs, the authors find that women who were enrolled in HMOs in 1987 were more likely to have received Pap smears and breast exams within the last year and to have ever received a mammogram when compared with women with fee-for-service coverage. By 1992, however, HMOs had lost this comparative advantage.

Paying for Primary Care: The Factors Associated with Physician Self-selection into Payment Models

To determine the factors associated with primary care physician self-selection into different payment models, we used a panel of eight waves of administrative data for all primary care physicians who practiced in Ontario between 2003/2004 and 2010/2011. We used a mixed effects logistic regression model to estimate physicians' choice of three alternative payment models: fee for service, enhanced fee for service, and blended capitation. We found that primary care physicians self-selected into payment models based on existing practice characteristics. Physicians with more complex patient populations were less likely to switch into capitation-based payment models where higher levels of effort were not financially rewarded. These findings suggested that investigations aimed at assessing the impact of different primary care reimbursement models on outcomes, including costs and access, should first account for potential selection effects.

Vulnerable populations and health insurance

This study provided a national profile of health insurance of certain vulnerable populations including children, racial/ethnic minorities, low-income families, non-metropolitan statistical area (MSA) residents, and those with poor health status. The study shows an increase in the proportion of uninsured nonelderly population. While public insurance helped reduce the employment- and health-related disparities in private coverage, it has not overcome other disparities related to vulnerable characteristics including race/ethnicity, wages, education, and area of residence. Comparison between health maintenance organization (HMO) and fee-for-service insurance indicates that younger although not much healthier people, racial/ethnic minorities, MSA residents, and those residing in the West and Northeast regions were more likely to have HMO coverage. To reduce significant disparities in health insurance coverage, policy makers will have to consider expanding public insurance coverage, targeting vulnerable groups, particularly those with multiple vulnerable characteristics rather than merely the economically distressed. Expecting managed care to achieve cost containment for services provided to vulnerable populations may be unrealistic.

Uptake of the centers for medicare and medicaid obesity benefit: 2012-2013

OBJECTIVE

To assess the use of the Medicare Obesity Benefit (MOB) by a licensed physician or associate provider in an outpatient setting in older adults.

METHODS

A serial cross-sectional analysis of fee-for-service Medicare claims (2012 and 2013) was used to assess the use of the MOB. Number and proportion of Medicare beneficiaries over age 65 using the benefit were assessed. Correlation between state-obesity rates and MOB uptake was determined based on state-specific obesity prevalence data from the Behavioral Risk Factor Surveillance System. Results There were 27,338 (0.10%) Medicare beneficiaries over age 65 in 2012 using the MOB and slightly more in 2013 (n = 46,821 [0.17%]). Mean age of MOB users in both years was 73 years, and 62% were females. Use declined with older age and was highest in the Northeast and lowest in the Midwest. High state obesity prevalence was not correlated with higher uptake of the MOB. Estimated proportion of persons with obesity using the MOB was 0.35% and 0.60% in successive years. A mean of 1.99 and 2.16 claims/MOB user was observed.

CONCLUSIONS

While the rate of MOB use increased in the second full year of its implementation, few were availing themselves of this benefit.

Provider Experiences with Chronic Care Management (CCM) Services and Fees: A Qualitative Research Study

BACKGROUND

Support for ongoing care management and coordination between office visits for patients with multiple chronic conditions has been inadequate. In January 2015, Medicare introduced the Chronic Care Management (CCM) payment policy, which reimburses providers for CCM activities for Medicare beneficiaries occurring outside of office visits.

OBJECTIVE

To explore the experiences, facilitators, and challenges of practices providing CCM services, and their implications going forward.

DESIGN

Semi-structured telephone interviews from January to April 2016 with 71 respondents.

PARTICIPANTS

Sixty billing and non-billing providers and practice staff knowledgeable about their practices' CCM services, and 11 professional society representatives.

KEY RESULTS

Practice respondents noted that most patients expressed positive views of CCM services. Practice respondents also perceived several patient benefits, including improved adherence to treatment, access to care team members, satisfaction, care continuity, and care coordination. Facilitators of CCM provision included having an in-practice care manager, patient-centered medical home recognition, experience developing care plans, patient trust in their provider, and supplemental insurance to cover CCM copayments. Most billing practices reported few problems obtaining patients' consent for CCM, though providers felt that CMS could better facilitate consent by marketing CCM's goals to beneficiaries. Barriers reported by professional society representatives and by billing and non-billing providers included inadequacy of CCM payments to cover upfront investments for staffing, workflow modification, and time needed to manage complex patients. Other barriers included inadequate infrastructure for health information exchange with other providers and limited electronic health record capabilities for documenting and updating care plans. Practices owned by hospital systems and large medical groups faced greater bureaucracy in implementing CCM than did smaller, independent practices.

CONCLUSIONS

Improving providers' experiences with and uptake of CCM will require addressing several challenges, including the upfront investment for CCM set-up and the time required to provide CCM to more complex patients.

The relation between managed care market share and the treatment of elderly fee-for-service patients with myocardial infarction

PURPOSE

To determine if greater managed care market share is associated with greater use of recommended therapies for fee-for-service patients with acute myocardial infarction.

SUBJECTS AND METHODS

We examined the care of 112,900 fee-for-service Medicare beneficiaries aged > or = 65 years who resided in one of 320 metropolitan statistical areas and who were admitted with an acute myocardial infarction between February 1994 through July 1995. Use of recommended medical treatments and 30-day survival were determined for areas with low (<10%), medium (10% to 30%), and high (>30%) managed care market share.

RESULTS

After adjustment for severity of illness, teaching status of the admission hospital, and area characteristics, areas with high levels of managed care had greater use of beta-blockers (relative risk [RR] for greater use = 1.18; 95% confidence interval [CI]: 1.06 to 1.29) and aspirin at discharge (RR = 1.05; 95% CI: 1.02 to 1.07), but less appropriate coronary angiography (RR = 0.93; 95% CI: 0.86 to 1.01) and reperfusion (RR = 0.95; 95% CI: 0.85 to 1.03) when compared with areas with low levels of managed care.

CONCLUSIONS

Medicare beneficiaries with fee-for-service insurance who resided in areas with high managed care activity were more likely to have received appropriate treatment with beta-blockers and aspirin, and less likely to have undergone coronary angiography following admission for myocardial infarction. Thus, the effects of managed care may not be limited to managed care enrollees.
