Differences in the obstetric malpractice claims filed by Medicaid and non-Medicaid patients.

BACKGROUND: Many physicians believe Medicaid patients are more likely than non-Medicaid patients to file malpractice claims. This study examines the accuracy of this belief in regard to obstetric malpractice claims. METHODS: Claims filed between January 1982 and June 1988 from the major malpractice insurer in Washington State were used to compare obstetric malpractice claims filed on behalf of Medicaid and non-Medicaid patients. RESULTS: Eleven percent (7/62) of all closed obstetric claims were filed by Medicaid patients, whereas 19 percent of all births in Washington State were to Medicaid patients between 1982 and 1988. Failure to diagnose or treat a fetal condition was the most commonly alleged negligence in both Medicaid and non-Medicaid groups. Most claims in both groups were settled before the cases went to court; a substantial minority of claims were dropped. The mean cost of Medicaid claims ($406,984) was three times that of non-Medicaid claims ($133,743), suggesting that paid Medicaid claims were more severe than paid non-Medicaid claims. CONCLUSIONS: Medicaid patients appear no more likely to file obstetric malpractice claims than non-Medicaid patients. The low likelihood of filing claims, coupled with large settlements, suggests that Medicaid patients may have less access to legal services than non-Medicaid patients.

Comparing the medical utilization and expenditures of low income health plan enrollees with Medicaid recipients and with low income enrollees having Medicaid eligibility.

The study examines the medical care (hospital, physician, drug, diagnostic) utilization and expenditures of low income persons enrolled in a prepaid health plan with a matched group of Medicaid recipients. The study also examines the medical care utilization of low income persons enrolled in a prepaid health plan with a similar group of low income persons enrolled in the health plan but also eligible for Medicaid benefits. Utilization and population-at-risk data were obtained from the Kaiser-Permanente Medical Care Program of Portland, Oregon and from the State of Oregon Welfare Division. A hypothesis of lower hospital utilization by low income enrollees compared with Medicaid recipients was accepted. A hypothesis of higher ambulatory care utilization was accepted for diagnostic procedures and prescription use, but rejected for office visit utilization. An analysis of the findings appeared to implicate the Medicaid program for differences observed. The hypotheses of no significant differences in inpatient and ambulatory medical care utilization of low income health plan enrollees with and without Medicaid eligibility were generally rejected. Low income enrollees with concurrent Medicaid had consistently higher utilization rates for all services resulting in substantially higher medical care expenditures per person. The findings appear to contribute some useful information to planning or establishing policy for Medicaid Prepayment programs or other programs enrolling low income persons in prepaid health plans or HMOs.

Optometric prescribing patterns: a quality comparison of Medicaid and non-Medicaid practitioners.

This study analyzes five variables related to quality and utilization of optometric prescribing of eyeglasses. The practices of optometrists participating in the New York City Medicaid Program were compared with those not participating. The variables chosen for this study can be analyzed by computer and seem to have wide applicability for monitoring of optometry services. Significant differences were found in four of the five variables under review. Overall, non-Medicaid patients appear to be receiving higher quality optometric care and less unnecessary care. Many of these differences, however, depend on the setting of the practice-whether solo, group, or corporate. Of additional note, wide variations occurred in the patterns of practice for non-Medicaid, as well as Medicaid, optometrists.

Nursing home costs, Medicaid rates, and profits under alternative Medicaid payment systems.

This analysis compares nursing home costs, Medicaid payment rates, and profits under three Medicaid nursing home payment systems: case-mix, facility-specific, and class-rate systems. Data used were collected from 135 nursing homes in seven states. The association of case mix with costs, rates, and profits under the three payment systems was of particular interest. Case mix was more strongly associated (positively) with patient care cost and the Medicaid rate for the case-mix systems than for the other systems, particularly the class-rate systems. In contrast, case mix and profits were not associated in the case-mix or facility-specific systems, but were negatively associated in the class rate systems. Overall, the results suggest that case-mix systems have some important advantages over other payment systems, but further research is needed on larger samples and involving the newer case-mix systems.

Factors associated with pediatricians' participation in Medicaid in North Carolina.

OBJECTIVE: To describe the relative importance of factors influencing pediatricians' participation in Medicaid in North Carolina. DESIGN: Questionnaire survey. SETTING AND PARTICIPANTS: Nonacademic primary care pediatricians in direct patient care at least 50% of the time; 332 (85%) of the 389 eligible pediatricians responded. MAIN OUTCOME MEASURES: Proportion of pediatricians who restricted Medicaid patients' access to their practices. The association between restricting access and the following factors was assessed: Medicaid reimbursement, pediatricians' demographic characteristics, knowledge of the Medicaid program, attitudes toward Medicaid patients and the Medicaid program, and beliefs about whether other physicians were available to care for Medicaid patients. RESULTS: Twenty-nine percent of pediatricians restricted Medicaid patients' access to their practices. The proportion of pediatricians restricting access was 62% in cities, 13% in medium-sized towns, and 12% in small towns (P less than .001), but the proportion of pediatricians in cities who restricted access varied from 87% to 22%. Pediatricians who received a higher proportion of their usual fee were less likely to restrict Medicaid patients' access. The relationship between Medicaid payment and restricted access was substantially weakened after controlling for the following factors: (1) the size of the community, (2) pediatricians' attitudes toward Medicaid payment, (3) their perceptions that they were too busy to care for Medicaid patients, and (4) whether there were other resources for the care of Medicaid patients. At comparable levels of payment, rural pediatricians were about six times less likely than urban pediatricians to restrict access. Pediatricians who knew less about Medicaid reimbursement also restricted access more often. Whether or not they restricted access to new Medicaid patients, pediatricians provided acute, preventive, hospital, and emergency care to the Medicaid patients who were already in their practices. CONCLUSIONS: Existing resources for the care of Medicaid patients, pediatricians' economic dependence on Medicaid, and the local norms of practice may be important factors in pediatricians' decision to participate in Medicaid. Increasing reimbursement will have only modest effects on Medicaid participation. Strategies to improve participation should also address pediatricians' knowledge of the Medicaid program and enlist the support of community physicians.

Physician participation in Medicaid: evidence from California.

The objective of this paper is to investigate physician participation in the Medicaid program. In particular, how sensitive is the physician's involvement with Medicaid to variations in Medicaid reimbursements? How important are fee levels in the private market? What is the impact of inflation on the costs of physicians' inputs, particularly if the Medicaid fee remains relatively constant? These questions are explored through an empirical analysis fo data from the California Medicaid program. Two aspects of physician participation form the focus of the study: 1) the percentage of physicians participating in Medicaid in a given county and 2) the average number of nonaged, Medicaid patients treated by each participating physician. Information on these variables and on Medicaid fees and private charges come from Medicare and Medicaid claims records for more than 3,000 physicians. The most significant result of the study is the reaffirmation of the importance of the amounts of both private charges and Medicaid payments in determining participation rates and average Medicaid case loads per participating physician. Both dependent variables are, as expected, inversely related to physicians' average billed revenue per patient and are positively related to average Medicaid payments per patient. In addition, it appears that the long-run impact of a change in billed revenue is significantly larger in absolute value than a corresponding change in the amount that Medicaid is willing to pay.

Medicaid prenatal care: a comparison of use and outcomes in fee-for-service and managed care.

BACKGROUND: To control rising costs, state Medicaid agencies are enrolling recipients in managed care health plans (MCPs). We performed this study to assess this policy's impact on accessibility and outcomes of Medicaid-funded prenatal care. METHODS: We performed a retrospective, controlled study with three cohorts: a study group of 1106 Medicaid recipients enrolled in three MCPs, a matched comparison group of 4830 recipients receiving care in the fee-for-service (FFS) system, and a second matched comparison group of 4434 non-Medicaid enrollees of the same MCPs. Data on prenatal care use and birth outcomes were obtained through linkage of claims and discharge files with birth certificate files. RESULTS: Medicaid recipients enrolled in MCPs used prenatal care similarly to those in the FFS system and showed equal or modestly improved birth-weight distributions. However, Medicaid MCP enrollees showed poorer use of prenatal care and birth outcomes compared with non-Medicaid enrollees of the same plans. CONCLUSIONS: Enrollment in MCPs has a neutral or small beneficial effect on the prenatal care received by the Medicaid population. However, providing financial access and modifying the system of care for this population did not result in parity with the general population.

Professional liability reform and access to Medicaid obstetric care in New York State.

Professional liability costs and fear of lawsuits have made participation in Medicaid difficult for office-based physicians who provide prenatal care, both obstetricians and family physicians. We assessed the possible impact of changes in three liability policy reforms on expanding access of Medicaid-eligible pregnant women to these private physicians. We surveyed members of the New York State District of the American College of Obstetricians and Gynecologists and the New York Academy of Family Physicians to explore whether they would start, expand, or resume obstetric service to Medicaid patients in response to a ceiling on litigation awards, no-fault insurance and a subsidy for liability expenses. We then compared the reported increases in participation on the basis of liability reforms to those in response to changes in Medicaid policies. We found in general that the three liability reforms would have similar impacts on Medicaid participation, although a subsidy was indicated by fewer physicians than the ceiling or no-fault approaches. The support for the liability reforms was as effective as proposals of greater reimbursement rates. The proportion of obstetricians or family physicians increasing their participation depended more on whether they would be starting Medicaid participation, expanding existing Medicaid participation or resuming former Medicaid participation than on the particular liability policy.(ABSTRACT TRUNCATED AT 250 WORDS)

Foreign medical graduates and Maryland Medicaid.

To determine whether foreign medical graduates provide a disproportionate share of medical care to the poor, Medicaid vendors in Maryland were compared with all licensed physicians in the State. Foreign medical graduates constitute 22 per cent of all physicians in Maryland but 36 per cent of the Medicaid vendors. In addition, of all the vendors for fiscal 1974, 94 per cent who were licensed in 1972 or 1973 were foreign medical graduates. This disproportional representation in the Medicaid program is concentrated in the specialties of general surgery, internal medicine and general practice. Thirty-two per cent of all foreign medical graduates in Maryland are board-certified physicians, but only 22 per cent of those who are Medicaid vendors are board certified. For United States medical graduates, 48 per cent of all physicians are board certified, but this figure increases to 52 per cent for the Medicaid vendors. Finally, representation of foreign medical graduates among Medicaid vendors tends to be highest in areas with the highest physician-to-population ratios and with the highest percentages of total Medicaid payments.

Use of community-based mental health programs by HMOs: evidence from a Medicaid demonstration.

BACKGROUND: Proposals to enroll Medicaid beneficiaries in health maintenance organizations (HMOs) have raised concerns that community-based mental health treatment programs would be adversely affected. METHODS: In Hennepin County (Minnesota) 35% of Medicaid beneficiaries were randomly assigned to prepaid plans. Random samples of individuals with severe mental illness with selected from the prepaid enrollees and from beneficiaries remaining with traditional Medicaid. The two groups were compared with respect to their use of community treatment programs and the write-off (the proportion of patient charges for which payment was not received) experienced by those programs for members of the study sample. RESULTS: There was no strong evidence that Medicaid beneficiaries with severe mental illness who were randomly assigned to prepaid plans used community-based mental health treatment programs differently than did other Medicaid beneficiaries. However, write-offs were consistently higher for enrollees in prepaid plans. CONCLUSIONS: In the short run, the use of community-based mental health treatment programs need not be affected by enrollment of Medicaid beneficiaries in prepaid plans, providing that Medicaid program administrators take steps to minimize the disruption of ongoing treatment, offer beneficiaries a choice among prepaid plans, and encourage community treatment programs to contract with plans to serve beneficiaries.

An evaluation of the impact of maternity care coordination on Medicaid birth outcomes in North Carolina.

BACKGROUND: Care coordination is an important component of the enhanced prenatal care services provided under the recent expansions of the Medicaid program. The effect of maternity care coordination services on birth outcomes in North Carolina was assessed by comparing women on Medicaid who did and did not receive these services. METHODS: Health program data files, including Medicaid claims paid for maternity care coordination, were linked to 1988 and 1989 live birth certificates. Simple comparisons of percentages and rates were supplemented by a logistic regression analysis. RESULTS: Among women on Medicaid who did not receive maternity care coordination services, the low birth weight rate was 21% higher, the very low birth weight rate was 62% higher, and the infant mortality rate was 23% higher than among women on Medicaid who did receive such services. It was estimated that, for each $1.00 spent on maternity care coordination, Medicaid saved $2.02 in medical costs for newborns up to 60 days of age. Among the women who did receive maternity care coordination, those receiving it for 3 or more months had better outcomes than those receiving it for less than 3 months. CONCLUSIONS: These results suggest that maternity care coordination can be effective in reducing low birth weight, infant mortality, and newborn medical care costs among babies born to women in poverty.

Geographic variation in physicians' fees. Payments to physicians under Medicare and Medicaid.

To study geographic differences in physician fees recognized by the Medicare and Medicaid programs, we analyzed physician reimbursement rates at the national, regional, state, and county levels. The results indicate that nationally, Medicaid specialist fees are 77% of Medicare specialist fees. Meidcare specialist fees in metropolitan areas are 23% higher than those in nonmetropolitan areas, but there are no differences under Medicaid. State Medicare specialist fees varied from 73% to 132% of the national Medicare average, while Medicaid specialist fees ranged from 49% to 179% of the national Medicaid average. State Medicaid fees for specialists ranged from 39% to 100% of Medicare specialist fees. These results indicate that under national health insurance, fees set at national or statewide levels could have notable effects on physician remuneration in some localities.

Can the psro's be cost effective? A study of the effect of the Commonwealth Health Agencies monitoring program on the length of stay of Medicaid patients in Massachusetts.

To analyze the effect of the Commonwealth Health Agencies Monitoring Program on the length of stay of a sample of Massachusetts Medicaid patients, we compared their experience with that of non-Medicaid patients. We found a consistently decreasing trend in the length of stay of Medicaid patients during the 2 1/2-year period studied. The average length of stay of Medicaid patients decreased by 11.9 per cent relative to the norm, whereas the non-Medicaid length of stay decreased by only 6.6 per cent. We infer that the Program may be credited within the 5.3 per cent differential decrease. The consistency and reliability of the data suggest that similar results may be extrapolated to the hospitals not sampled. We conclude that Professional Standards Review Organizations, of which this program was a precursor, can be cost effective, given an expanded review mandate and the application of suibable evaluative processes.

Medicaid, morbidity, and physician use.

Medical programs which provide services for low-income persons who have high medical needs have been criticized for high costs and have raised questions about overuse of physician services. A Baltimore SMSA household interview of use of health services permitted comparison of use of physician and preventive services controlled for morbidity by Medicaid recipients and two other income groups. Medicaid recipients were sickest and had higher physician use. They were more likely to have visits suggested by a physician, to be asked to return, and to be given injections. Physician visit rates were higher for each morbidity category, particularly for Medicaid healthy, who also used more preventive services in two weeks. Higher use of services by Medicaid recipients is accounted for by higher morbidity and increased need and demand for preventive services. Constraints on the use of physician services now most directly affect use of preventive services by those of low income without Medicaid benefits in the Baltimore SMSA.

Medicaid records as a valid data source: the Tennessee experience.

Health care researchers rarely employ Medicaid claim files as a data base, in part because they are designed to serve fiscal and administrative ends. Indeed, some investigators have emphasized the deficiencies in such records. In contrast, we have found Tennessee Medicaid data to be suitable for research. A statewide automated data processing system reduces the occurrence of many of the errors noted by others. Further, analysis of the July 1974 month of payment file illustrates the accuracy and internal consistency of Tennessee Medicaid data. Specimen legend drug results for ambulatory patients suggest investigations of physician prescribing patterns. Evaluation of the Medicaid claims processing system suggests other applications in health care administration and research. In a time when available resources are dwindling, the incisive use of Medicaid claims files offers an attractive alternative to expensive new systems of data collection and analysis.

Encouraging preventive services for low-income children. The effect of expanding Medicaid.

Every year since 1984, Congress has expanded Medicaid to cover an increasing proportion of low-income children. In this study, a multivariate analysis of data from the 1987 National Medical Expenditure Survey was used to determine whether expanded Medicaid eligibility is likely to be effective in encouraging recommended preventive visits for low-income, preschool children. For low-income children who would otherwise be uninsured, a full year of Medicaid increased the probability of any well-child visits by 17 percentage points, and compliance with the guidelines of the American Academy of Pediatrics for well-child visits increased by 13 percentage points. The generosity of Medicaid fees did not alter the magnitude of these effects. However, even if all uninsured children under 200% of the poverty line were eligible for Medicaid, low-income children would continue to lag behind other children in their use of preventive services. Factors other than insurance and income, such as the lower educational attainment of low-income mothers, explain approximately 80% of the gap between children above and below 200% of poverty. The rate of compliance with the American Academy of Pediatrics guidelines was less than 50% for all preschool children. Departures from the recommended schedule of visits were particularly pronounced in the second year of life and may interfere with children receiving the recommended immunizations in a timely manner.

HMOs for Medicaid: the road to financial independence is often poorly paved.

During the 1980s both the federal government and the private sector articulated policies to encourage the development and participation of health maintenance organizations (HMOs) in the Medicaid program. However, the policies, intended to save costs, limited the ability of new HMOs to achieve financial independence. New plans that emphasize Medicaid participation have few, if any, options on benefit design or in setting capitation rates. Relative to fee-for-service Medicaid programs, their costs to provide services may be quite high, as they have neither the buying power not the ability to impose discounts. As a consequence, plans must focus their financial planning efforts on targeting and attaining a stable enrollment base and on controlling the amount of services provided, tasks that are difficult for all HMOs. Achieving a stable enrollment base is particularly hard because Medicaid eligibles have few incentives to enroll and once enrolled often lose their Medicaid eligibility. Traditional HMOs control the amount of services provided through physician selection, financial incentives on physicians, and monitoring and utilization review. Lack of information and the difficulty inherent in attracting sufficient provider participation limit the first two strategies, so new plans often adopt organization structures that rely heavily on monitoring activities. Unfortunately, management information systems for HMOs are often the weakest link. We discuss the tasks and present data on financial planning, on putting financial plans into operation, and on monitoring progress toward financial independence for a set of ten demonstration projects sponsored by the Robert Wood Johnson Foundation.
