Quality management practices in Medicaid managed care: a national survey of Medicaid and commercial health plans participating in the Medicaid program.

CONTEXT: Rapid expansion of Medicaid managed care has raised concerns about the capacity and willingness of health plans enrolling Medicaid beneficiaries to provide high-quality care. Recently, legislation has facilitated market entry of Medicaid plans, health plans that draw most of their enrollment from the Medicaid population. OBJECTIVE: To characterize and compare the organizational characteristics and programs related to quality of care of commercial and Medicaid health plans that participate in the Medicaid program. DESIGN: Cross-sectional survey conducted September 1997 to April 1998. SETTING: The Medicaid program in 11 states and the District of Columbia. PARTICIPANTS: All 154 health plans in these localities that provided prepaid general medical care to Medicaid beneficiaries during June 1997, of which 130 (84%) responded to the survey. MAIN OUTCOME MEASURES: Health plan reports of structural characteristics, services offered, performance measurement and feedback, disease management programs, information systems capabilities, and provider network composition and relationships. RESULTS: Half of the respondents were Medicaid plans, with 75% or more of enrollees drawn from the Medicaid population. Medicaid plans tended to be smaller and newer than commercial plans that also served the Medicaid population and had more enabling programs targeting the special needs of the Medicaid population, such as inadequate transportation (85% of Medicaid plans vs 62% of commercial plans; P = .003) and illiteracy (66% vs 38%, respectively; P = .002). Overall, 71% of Medicaid plans vs 43% of commercial plans had enabling programs targeted at 6 or more of the 8 special needs we specified (P = .001). While commercial plans had a higher proportion of board-certified primary care physicians (81% vs 73%; P = .01), we found no major differences between Medicaid plans and commercial plans in collection and dissemination of performance measures, designation of specific areas for quality improvement, or use of disease management programs targeted at conditions prevalent in the Medicaid population. Neither commercial nor Medicaid plans reported high success in improving quality of care. CONCLUSIONS: Based on our survey, while Medicaid plans resemble commercial plans serving the Medicaid population in many aspects of quality management, they are more likely to target programs directed to the specific needs of the Medicaid population. Neither commercial nor Medicaid plans have notably strong records in actual quality improvement.

Can Medicaid managed care provide continuity of care to new Medicaid enrollees? An analysis of tenure on Medicaid.

OBJECTIVES: The purpose of this study was to analyze duration of coverage among new Medicaid enrollees. METHODS: The 1991 Survey of Income and Program Participation was used to examined the duration of coverage for individuals who did not have Medicaid in January 1991 and obtained coverage by May 1993. RESULTS: Of new Medicaid enrollees, 38% (90% confidence interval [CI] = 34%, 42%) remained covered 1 year later; 26% (90% CI = 21%, 31%) remained covered at 28 months. Of those older than 65 years, 54% (90% CI = 31%, 77%) retained Medicaid for 28 months, vs 20% (90% CI = 14%, 26%) of children. Of people who lost Medicaid, 54% (90% CI = 31%, 77%) had no insurance the following month. CONCLUSIONS: Almost two thirds of new Medicaid recipients lose coverage within 12 months. It is unlikely that Medicaid managed care will enhance continuity of care for new recipients.

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 asthma care for Medicaid and non-Medicaid children in a health maintenance organization.

OBJECTIVE: To compare ambulatory visit patterns, rates of medication use, and emergency department and hospital utilization for children with asthma covered under Medicaid and commercial payers within the same health maintenance organization (HMO). DESIGN: Retrospective cohort study. SETTING: Eleven staff-model pediatric departments of an HMO. PATIENTS: A total of 1928 Medicaid and 11007 non-Medicaid children aged 2 to 18 years with at least 1 encounter with a diagnosis of asthma between October 1, 1991, and September 30, 1996. METHODS: We linked patient-level data from the HMO's automated medical record system for ambulatory encounters, a claims system for emergency department and hospital care, and an automated pharmacy dispensing database. Medicaid and non-Medicaid patients were compared for all encounter types and for prescribing and dispensing of beta-agonist and controller medications (inhaled corticosteroids and cromolyn sodium). Incidence rate ratios were calculated from Poisson regression models to control for age, sex, and, when appropriate, beta-agonist dispensing rate. The number of refills authorized on each prescription and the fraction of medications dispensed as refills compared with new prescriptions were compared for Medicaid and non-Medicaid patients. RESULTS: Medicaid-insured children in the HMO were 1.4 times (95% confidence interval, 1.2-1.5) more likely to receive care in emergency departments and 1.3 times (95% confidence interval, 1.1-1.5) more likely to be hospitalized for their asthma compared with non-Medicaid members. Medicaid and non-Medicaid enrollees had similar yearly rates of nonurgent (1.32 vs 1.17) and urgent (0.38 vs 0.31) ambulatory visits. Beta-agonists were dispensed roughly equally to Medicaid and non-Medicaid members. Although Medicaid patients were less likely to have controller medications dispensed (relative risk, 0.72; 95% confidence interval, 0.69-0.74), they were equally likely to have them prescribed. CONCLUSIONS: Differences in ambulatory contact for Medicaid members do not explain the higher rates of emergency department visits and hospitalization in this population. Reasons for lower rates of dispensing of controller medications should continue to be investigated as one cause of increased morbidity for low-income children with asthma.

Medicaid acceptance and availability of timely follow-up for newborns with Medicaid.

OBJECTIVE: Decreased physician participation in Medicaid has been shown to affect adversely timeliness of adult acute care and pediatric specialty care, but it is not clear whether this is the case for newborn follow-up. The objectives of this study were to determine whether there is a difference within clinics in the timeliness of follow-up appointments that are given to newborns with Medicaid compared with newborns with private insurance and to determine whether there is a difference between clinics that do and do not accept Medicaid in the timeliness of appointments that are given for newborn follow-up. METHODS: A randomized crossover study was conducted among general pediatric clinics and practices that were identified from the yellow pages and Internet searches of hospitals and health departments in 8 metropolitan areas from September 2003 to March 2004. A simulated parent telephoned clinics to find the earliest available appointment for a 1-day-old infant who needed routine follow-up after discharge that day. Clinics were randomly assigned to receive a first call from a patient with either Medicaid or private insurance; each clinic received the same call at least 3 weeks later with the patient's insurance status reversed. The main outcome measure was whether the appointment was timely (< or =2 days from the day of the call). RESULTS: Of 401 participating clinics, 22% did not accept Medicaid. Among clinics that accepted Medicaid, availability of a timely appointment for a newborn with Medicaid was similar to that for a newborn with private insurance (87% vs 90%, respectively). Appointments that were provided to privately insured newborns were as likely to be timely in clinics that accept Medicaid as in clinics that do not accept Medicaid (89.5% vs 93.4%, respectively). However, providing timely appointments was significantly less likely in clinics that were in high-poverty locations compared with clinics that were not (86.1% vs 92.7%, respectively). CONCLUSIONS: Although newborns with Medicaid did not have access to >20% of clinics because of their insurance, among clinics that did accept Medicaid, timeliness of available follow-up was similar for newborns with Medicaid compared with newborns with private insurance and similar between clinics that did and did not accept Medicaid. However, to the extent that care for newborns with Medicaid is concentrated in clinics in high-poverty areas, some newborns with Medicaid may not be able to receive timely appointments.

Accuracy of Medicaid payer coding in hospital patient discharge data: implications for Medicaid policy evaluation.

BACKGROUND: Ambulatory care-sensitive hospitalization rates derived from hospital discharge data have been used to compare ambulatory care across insurance and delivery system groups. OBJECTIVE: We sought to quantify the impact of coding inaccuracies in hospital discharge data on counts of hospitalizations for ambulatory care-sensitive conditions among Medicaid beneficiaries. METHODS: This was a cross-sectional comparison of administrative databases of all California Medicaid beneficiaries younger than 65 years of age. We compared the number of hospitalizations that were attributed to Medicaid beneficiaries in California's hospital discharge data for 1994 to 1999 with the number derived from a file that linked hospital discharge data with the Medicaid eligibility file. RESULTS: Hospital discharge data undercounted 28.2% of hospitalizations for ambulatory care-sensitive conditions among Medicaid beneficiaries and overcounted 13.4% of such admissions among non-Medicaid beneficiaries. Approximately 5% of hospitalizations for ambulatory care-sensitive conditions captured as Medicaid admissions in routine hospital discharge data were among patients who gained Medicaid coverage as a result of the hospitalization. Patients who acquire Medicaid coverage as a result of a hospitalization are much more likely to be placed into Medicaid fee for service rather than Medicaid managed care which biases comparisons of these 2 delivery models. CONCLUSION: Caution should be used in the interpretation of Medicaid hospitalization rates as calculated from routine hospital discharge data. State agencies that provide hospital discharge data should consider the opportunity to improve the evaluation of Medicaid services by linking hospital discharge data with Medicaid enrollment files.

The impact of Medicaid managed care on primary care physician participation in Medicaid.

OBJECTIVES: Medicaid managed care has been touted as an important vehicle for increasing physician participation in Medicaid. Although there is anecdotal evidence that the opportunity to participate in Medicaid via managed care increases physician participation, no empirical study has validated the claim. This study explores the relationship between Medicaid managed care penetration at the county-level and the likelihood that a physician practicing in that county will participate in Medicaid. RESEARCH DESIGN: We used 3 waves of a large, nationally representative sample of primary care physicians from the Community Tracking Study followed across time (1996-2001) to estimate the impact of changing Medicaid managed care penetration levels on physician participation in the program. County-level Medicaid managed care penetration rates were collected directly from state Medicaid agencies for the study. FINDINGS: In cross-sectional bivariate and multivariate analyses, Medicaid managed care penetration is significantly associated with physician participation in Medicaid; however, the relationship is nonmonotonic, of small magnitude and generally not in the anticipated direction. Our analyses indicate that a 10 percentage point increase in managed care penetration would reduce the likelihood that physicians participate in Medicaid on average by 2.9 percentage points. Although commercial MCO penetration exhibited a small positive, linear relationship with physician participation, this was not sufficient to offset the effects of Medicaid-dominant MCO penetration. Panel data analysis supported these findings. CONCLUSIONS: This study failed to find that increases in Medicaid managed care lead to increased primary care physician participation in Medicaid during the period 1996-2001.

Dentists' ranking of Medicaid reimbursement rates as a measure of their pediatric Medicaid participation.

The objective of the study was to determine the usefulness of dentists' ranking of Medicaid reimbursement rates as a measure of their participation in the Medicaid program for children. Data were obtained from two mail-in questionnaire surveys of Connecticut dentists, before and after an increase in Medicaid reimbursement rates for children. Dentists ranked acceptability of Medicaid reimbursement rates on a seven-point index, while their participation in the Medicaid program was assessed by whether they acknowledged treating Medicaid children and were currently accepting new Medicaid children into their practices. There was a significant difference (p < 0.0001) in the dentists' ranking of Medicaid reimbursement rates following the rate increase indicating that the index was responsive. Acceptance of new Medicaid children into dental practices was a better measure of active participation in the Medicaid program. Following the increase in Medicaid reimbursement rates, dentists ranking it as acceptable/equivocal were more likely (p < 0.02) to accept new Medicaid children into their practices. In conclusion, the index of dentists' ranking of Medicaid reimbursement rates was a responsive and valid measure of their participation in the Medicaid program.

Ability of Medicaid claims data to identify incident cases of breast cancer in the Ohio Medicaid population.

BACKGROUND: The use of Medicaid data to study cancer-related outcomes would be highly desirable. However, the accuracy of Medicaid claims data in the identification of incident cases of breast cancer is unknown. OBJECTIVES: (1) To estimate the sensitivity of Medicaid claims data for case ascertainment of breast cancer, and (2) to determine the positive predictive value (PPV) of diagnostic and procedure codes retrieved from Medicaid claims, using the Ohio Cancer Incidence Surveillance System (OCISS) as the gold standard. METHODS: The study used the linked OCISS and Medicaid enrollment files, 1997-1998 (n = 1,648). The claims search yielded 2,635 incident cases, of which 1,132 were also identified through the OCISS-Medicaid files. Sensitivity and PPV of Medicaid data were calculated in subgroups of the population. RESULTS: The overall sensitivity was 68.7 percent, but varied greatly across the subgroups of the population. It was lower among women enrolled in Medicaid only for part of the study year than those enrolled in Medicaid for 12 months of the study year (56.7 percent and 78.0 percent respectively, p < 0.0001), and lower among those who are dual Medicare-Medicaid eligible compared to those not participating in the Medicare program (63.1 percent and 78.6 percent respectively, p < 0.0001). The overall PPV was 43.0 percent, increasing up to 86.6 percent in the presence of procedure codes indicating the presence of mastectomy and lumpectomy, in addition to that of breast cancer diagnosis. CONCLUSIONS: The sensitivity of Medicaid claims for case ascertainment of breast cancer is somewhat low, but improves considerably when accounting for women enrolled in Medicaid for the entire duration of the study year. The PPV is poor due to a high rate of false positives. The higher PPV obtained in the presence of procedure codes, in addition to diagnosis codes, will help researchers to correctly identify incident cases of breast cancer using Medicaid claims data.

The contribution of Medicaid managed care to the increasing undercount of Medicaid beneficiaries in the Current Population Survey.

BACKGROUND: The Current Population Survey (CPS) is an important source of data for comparing beneficiaries across insurance groups. However, the CPS routinely underestimates the Medicaid population, and for unexplained reasons these underestimates have been increasing over time. OBJECTIVE: We sought to determine whether the penetration of Medicaid managed care is associated with the magnitude of the underestimate of Medicaid beneficiaries in the CPS using a pooled cross-sectional comparison of survey and administrative databases on all California Medicaid beneficiaries younger than 65 years of age. MEASURES: We compared the CPS estimates of Medicaid beneficiaries in California from 1995 to 1999 with the gold-standard number derived from the Medicaid eligibility file for the same time period and examined the association between the CPS underestimate and penetration of managed care in the beneficiary's county. RESULTS: The CPS underestimated the Medicaid population by approximately a third. At the county level, errors in estimated numbers of Medicaid beneficiaries in the CPS increased in association with the penetration of Medicaid managed care. Each percentage point increase in the penetration of managed care was associated with an underestimate in the CPS of 0.4 percentage points. CONCLUSION: A substantial portion of the increase in the underestimates of the number of Medicaid beneficiaries in the CPS can be explained by the growth of Medicaid managed care. Steps must be taken to improve the CPS if this survey is to remain useful for making accurate estimates of Americans' health insurance status.

Do quality improvement strategies for Medicaid enrollees differ in Medicaid-dominant versus commercial managed care organizations?

OBJECTIVE: To examine whether it matters, in terms of quality improvement initiatives and access to commercial networks, whether states contract with Medicaid-dominant or commercial managed care plans. STUDY DESIGN: A 2001 telephone survey of Medicaid managed care plans in 11 states that together account for about half of the national Medicaid managed care enrollment. METHODS: The survey was developed in consultation with a panel of individuals knowledgeable about Medicaid managed care. Information on plan characteristics and network design was obtained from the plan CEO or person most knowledgeable about the topics. The rest of the data were obtained from the person the CEO named as most knowledgeable about quality improvement initiatives. RESULTS: Surveyed plans reported an extensive array of quality improvement initiatives. Programs are in many ways similar across Medicaid-dominant and commercial plans. Medicaid-dominant plans tend to specialize more in conditions of greatest priority to Medicaid beneficiaries. Commercial plans tend to develop programs for accreditation by the National Committee for Quality Assurance, and to limit measurement specific to the Medicaid population. They draw on their commercial networks to support the Medicaid product line, but how much they expand provider access is not clear. Both types of programs face barriers that limit the effectiveness of the plans' initiatives. CONCLUSION: This study shows extensive development of quality initiatives in Medicaid managed care plans, with limited differences across Medicaid-dominant and commercial plans.

Medicare and Medicaid home health and Medicaid waiver services for dually eligible older adults: risk factors for use and correlates of expenditures.

PURPOSE: The purpose of this work was to, among frail dually eligible older adults, determine risk factors for the likelihood of using Medicare home health and Medicaid home health services and to, among service users, determine correlates of Medicare home health, Medicaid home health, and Medicaid waiver service expenditures. DESIGN AND METHODS: Dually eligible individuals enrolled in Connecticut's Medicaid home- and community-based services (HCBS) waiver program for the aged (N = 5,232) were identified from a statewide database containing person-level linked data from Medicare claims, Medicaid claims, and uniform clinical assessment forms. Expenditures, based on claims data, were observed from the month following clinical assessment over the period August 1995 to December 1997. RESULTS: In multivariate models controlling for medical conditions and sociodemographic variables, similar functional disability measures were strongly associated with the probability of the use of, and expenditures for, Medicare home health and Medicaid home health services; severe cognitive impairment was strongly associated with greater Medicaid waiver service expenditures. IMPLICATIONS: Given the similarity of factors associated with Medicare and Medicaid home health service use and expenditures, greater integration of Medicare and Medicaid financing, reimbursement, and delivery strategies for home health services may be feasible and warranted for dually eligible older adults enrolled in state Medicaid HCBS waiver programs.

The effects of medicaid reimbursement on the access to care of medicaid enrollees: a community perspective.

Previous research has not found a strong association between Medicaid reimbursement levels and enrollees' access to medical care, even though higher fees increase the acceptance of Medicaid patients by physicians. This study shows that high Medicaid acceptance rates by physicians in a community are more important than fee levels per se in affecting enrollees' access to medical care. Although high fee levels increase the probability that individual physicians will accept Medicaid patients, high fee levels do not necessarily lead to high levels of physician Medicaid acceptance in an area. Numerous other physician practice, health system, and community characteristics also affect Medicaid acceptance. The effects of Medicaid fees on Medicaid acceptance are substantially lower in areas with high Medicaid managed care penetration and for physicians who practice in institutional settings. The results suggest that a broad range of factors need to be considered to increase access to physicians for Medicaid enrollees.

Impact of Maine's Medicaid drug formulary change on non-Medicaid markets: spillover effects of a restrictive drug formulary.

BACKGROUND: Market penetration of HMOs affect physician practice styles for non-HMO patients. OBJECTIVE: To study the impact of a restrictive Medicaid drug formulary on prescribing patterns for other patients, ie, so-called spillover effects. DESIGN: A before-and-after, 3-state comparison study. EVENT: On January 1, 2001, Maine's Medicaid program implemented a restrictive drug formulary for the proton pump inhibitor class, with pantoprazole as the only preferred drug. MAIN OUTCOME MEASURE: The Medicaid and non-Medicaid market shares of pantoprazole in Maine (vs New Hampshire and Vermont and among Maine physicians with different Medicaid share of practice. RESULTS: After 3 months, the market share of pantoprazole in Maine (vs 2 control states) increased 79% among Medicaid prescriptions (vs 1%-2%), 10% among cash prescriptions (vs 3%), and 7% among other third-party payer prescriptions (vs 1%). The market shares increased more among Maine physicians with a higher Medicaid share of practice (high vs middle vs low [market]: 16% vs 8% vs 5% [cash]; 11% vs 5% vs 4% [other third-party payers]). Linear regression results indicate that practicing medicine in Maine leads to a 72% increase in pantoprazole share among Medicaid prescriptions (P < .001). In addition, for each 10% Medicaid share of practice in Maine, the share of pantoprazole increases 1.8% among cash prescriptions (P = .01) and 1.4% among other third-party payer prescriptions (P < .001). CONCLUSIONS: Maine's Medicaid drug formulary generated spillover effects in cash and other third-party payer markets, with somewhat stronger effects in the cash market.

Medicaid program; relations with other agencies, miscellaneous Medicaid definitions, third party liability quality control, and limitations on federal funds for abortions--HCFA. Final rule.

These final regulations (1) revise Medicaid rules to reflect current policy on State payment of cost sharing amounts under Medicare Part B "buy-in" agreements; (2) revise and clarify certain Medicaid definitions; (3) remove the requirement that State plans include third party liability quality control reviews as part of the State's Medicaid quality control systems; and (4) provide for limitations on the use of Federal funds for abortion. These final regulations allow States with Medicare Part B buy-in agreements the option of paying cost sharing amounts for Medicaid beneficiaries for those Medicare services that States do not cover in their Medicaid plans. States may pay cost sharing amounts under Medicare Part B buy-in agreements on all, some or none of the Part B Medicare services that are covered in the Medicaid plan. We are revising definitions and clarifying ambiguities in several existing Medicaid regulations. The revisions are to the definitions of private duty nursing services, inpatient and outpatient, inpatient and outpatient hospital services, and other laboratory and x-ray services. We are removing the requirement in our quality assurance regulations that States monitor third party liability errors as a part of their quality control system. Instead, we plan to issue regulations which encourage improved third party liability (TPL) operations by making them an integral component of State Medicaid Management Information System subject to periodic evaluation through systems performance reviews. We are revising the Medicaid regulations to provide for limitations on the use of Federal funds for abortion, in accordance with previously enacted laws.

Examining differences in death rates for medicaid and non-medicaid nursing home residents.

OBJECTIVES: The purpose of this work was to examine differences in the probability of death for Medicaid and privately funded nursing home residents, controlling for differences in facility, market, and resident characteristics. METHODS: Given that Medicaid residents are more likely to die in nursing facilities, the probability of dying within 1 or 2 years is estimated using a series of probit models, controlling for whether a resident is Medicaid-funded or privately-funded. As resident characteristics, market attributes, facility characteristics, and facility fixed effects are sequentially added to the specifications, the gap in the probability of death between Medicaid and private-pay residents is considered. RESULTS: The overall mortality rate for Medicaid residents was 14.8% points higher than the death rate for privately funded residents. When considering death within 1 year and 2 years, Medicaid resident death rates were 4.2% and 7.8% higher, respectively. The apparent difference in mortality declines as one controls for resident, market, and facility characteristics. Both facility characteristics and facility fixed effects are relatively important in explaining differences in death rates between Medicaid and private-pay residents. CONCLUSIONS: Differences in death rates between Medicaid and private-pay residents are relatively small, suggesting that residents with different payment sources are not treated differently in nursing homes in ways that impact the probability of death. However, policymakers may want to look more closely at whether Medicaid residents are segregated into lower-quality facilities.

Comparison of Medicaid and non-Medicaid dental providers.

A statewide mail survey of a stratified sample of 640 Michigan general dentists was conducted in 1983, with a response rate of 41 percent, n = 261. An analysis was performed to compare Medicaid and non-Medicaid providers. About half of all respondents reported that they were not seeing any Medicaid patients (Group 1); 29 percent reported that less than 10 percent of their patients were Medicaid-eligible (Group 2), and 22 percent reported that 10 percent or more of their patients were Medicaid-eligible (Group 3). Significant differences existed among the three groups for age of respondent, length of time in practice, and number of new patients seen each month. Respondents with greater percentages of Medicaid patients in their practices were more likely to be in group practice. Stratification of respondents by location suggested that rural providers were more likely than urban respondents to have some Medicaid patients in their practices. Over 40 percent of respondents from all groups reported themselves as being not busy enough. In 1984, more than one million persons in Michigan were eligible for Medicaid dental benefits, but only one-fourth of these individuals were recipients of dental care. Factors that may limit dentists' participation in the Medicaid program, despite the presence of a large eligible population and self-reported lack of business, are discussed.
