Use of preventive services by Medicare fee-for-service beneficiaries: does spillover from managed care matter?

BACKGROUND: Health care delivery varies with the level of managed care activity (MCA) in an area, potentially affecting health care for those not participating in managed care programs. However, the extent to which MCA is associated with the use of cancer screening by fee-for-service beneficiaries (FFS) is unclear. OBJECTIVE: We sought to study colorectal cancer screening among Medicare FFS beneficiaries in relation to levels of Medicare MCA. RESEARCH DESIGN: This study linked 1999 Medicare denominator and Part B claims data with the 1998 Area Resource File. After categorizing MCA as low (<10%), moderate (10-29.99%), or high (> or =30%), we assessed the association between colorectal cancer screening among FFS beneficiaries and MCA, controlling for individual demographic variables and county-level attributes of socioeconomic status and physician resources. SUBJECTS: We included Medicare FFS beneficiaries 65 years of age or older with both Part A and Part B coverage for the entire calendar year from large counties in the study. MEASURES: We measured the likelihood of undergoing fecal occult blood testing (FOBT), flexible sigmoidoscopy (FLEX), or colonoscopy (COL). RESULTS: Compared with Medicare FFS beneficiaries residing in counties with low MCA, those in high MCA counties were significantly more likely to undergo FOBT (adjusted odds ratio [AOR] 1.10, 95% confidence interval [CI] 1.04-1.16), FLEX (AOR 1.11, 95% CI 1.04-1.18), or colonoscopy, after receiving FOBT/FLEX (AOR 1.07, 95% CI 1.02-1.13). CONCLUSIONS: From a public health perspective, an association between higher levels of MCA and colorectal cancer screening among those not enrolled in managed care may translate into modest increases in use of colorectal cancer screening and possibly earlier detection.

Report from the front lines: rural Medicaid primary care providers as gatekeepers of rural health service networks.

This study of primary care practitioners in Louisiana's Medicaid managed care program, Community Care, focused on the program's implementation and perceived impact. PCPs were interviewed to assess their perceived responsibilities as gatekeepers and how well they believed the system facilitated or impeded their fulfillment of those responsibilities, to examine issues of access and quality, and to determine their knowledge and use of local referral networks. Findings indicate that although they appreciated the financial stability derived from having a larger patient base and understood their roles well, they were concerned with several facets of the program, including perceived limitations imposed on their medical decision making, an added burden of paperwork, and a lack of both downward and upward communication. They also believed the referral network of available providers for medical and social services to be more limited for their Medicaid patients than for their private patients. Policy implications are discussed.

Healthcare reform in Puerto Rico. Managed care in a unique environment.

To reduce healthcare costs, Puerto Rico has adopted an innovative managed-care program to replace its old public healthcare system. Under the new program, healthcare funding for the medically indigent is being transferred from government-run hospitals and clinics to contracted private insurers who provide a wide range of services on a capitated payment plan. This well-planned initiative addresses the need to cut healthcare costs in Puerto Rico, but whether it will successfully meet the healthcare needs of beneficiaries in the long run is up for debate.

Preconception counseling for the primary care physician.

All health care providers that interact with women of childbearing age should understand the potential benefits of preconception counseling and to approach the evaluation in a thorough manner during routine health maintenance visits. With the increased number of patients enrolled in managed care programs, health maintenance visits provide the unique opportunity to educate women contemplating pregnancy regarding the potential influences of their lifestyle and health status on the future pregnancy. It is becoming increasingly apparent that interventions made during the preconception period are just as crucial as the subsequent 9 months of prenatal care to achieve an optimal maternal-fetal outcome. Some guidelines for the preconception evaluation have been provided, and the implications of chronic medical illness on pregnancy have been discussed.

Principal-agent theory: a framework for improving health care reform in Tennessee.

Using a framework based on principal-agent theory, this study examines problems faced by managed care organizations (MCOs) and major health care providers under the state of Tennessee's current capitation-based managed care programs called TennCare. Based on agency theory, the study proposes a framework to show how an effective collaborative relationship can be forged between the state of Tennessee and participating MCOs which takes into account the major concerns of third-party health care providers. The proposed framework further enhances realization of the state's key health care reform goals which are to control the rising costs of health care delivery and to expand health care coverage to uninsured and underinsured Tennesseans.

Peer review of the quality of care. Reliability and sources of variability for outcome and process assessments.

CONTEXT: Peer assessments have traditionally been used to judge the quality of care, but a major drawback has been poor interrater reliability. OBJECTIVES: To compare the interrater reliability for outcome and process assessments in a population of frail older adults and to identify systematic sources of variability that contribute to poor reliability. SETTING: Eight sites participating in a managed care program that integrates acute and long-term care for frail older adults. PATIENTS: A total of 313 frail older adults. DESIGN: Retrospective review of the medical record with 180 charts randomly assigned to 2 geriatricians, 2 geriatric nurse practitioners, or 1 geriatrician and 1 geriatric nurse practitioner and 133 charts randomly assigned to either a geriatrician or a geriatric nurse practitioner. MAIN OUTCOME MEASURES: Interrater reliabilities for structured implicit judgments about process and outcomes for overall care and care for each of 8 tracer conditions (eg, arthritis). RESULTS: Outcome measures had higher interrater reliability than process measures. Five outcome measures achieved fair to good reliability (more than 0.40), while none of the process measures achieved reliabilities more than 0.40. Three factors contributed to poorer reliabilities for process measures: (1) an inability of reviewers to differentiate among cases with respect to the quality of management, (2) systematic bias from individual reviewers, and (3) systematic bias related to the professional training of the reviewer (ie, physician or nurse practitioner). CONCLUSIONS: Peer assessments can play an important role in characterizing the quality of care for complex patients with multiple interrelated chronic conditions, but reliability can be poor. Strategies to achieve adequate reliability for these assessments should be applied. These strategies include emphasizing outcomes measurement, providing more structured assessments to identify true differences in patient management, adjusting systematic bias resulting from the individual reviewer and their professional background, and averaging scores from multiple reviewers. Future research on the reliability of peer assessments should focus on improving the ability of process measures to differentiate among cases with respect to the quality of management and on identifying additional sources of systematic bias for both process and outcome measures. Explicit recognition of factors influencing reliability will strengthen efforts to develop sound measures for quality assurance.

Self-directed health plans: alternatives to managed care enabled by new technologies.

Few people believed the Internet would have much impact on the delivery of health care services. However, combined with technological advances in how computer systems are structured and implemented and knowing what doesn't work in managed care from bitter experience, the Internet is being used to create a new paradigm of alternative health insurance products. These products hold the potential to change for the better the face of health care as we know it. Self-directed health plans will be less expensive than managed care programs and offer greater predictability in health care spending. For health care providers, SDHPs' reliance upon episode allowances will create a new market for packaged or bundled services. Providers will be paid to provide solutions, not just treatment. This could represent a new model in which physicians accept a risk-adjusted payment and provide a warranty that they will do whatever necessary until the patient has reached the reasonably expected health status. This is a radical departure from the fee-for-service or capitation system.

Ruptured appendicitis among children as an indicator of access to care.

OBJECTIVE: To determine factors associated with ruptured appendicitis among children, using administrative databases. Insurance-related differences in the risk of ruptured appendix among adults in California have previously been described (Braveman, Schaaf, Egerter, et al. 1994). DATA SOURCES/STUDY SETTING: State of Maryland Medicaid claims data for children < or = 18 years of age from 1989 to 1993 and hospital discharge data for children < or = 19 years of age from 1989 to 1994 were analyzed. STUDY DESIGN: Administrative data analysis pre- and post-implementation of a Medicaid managed care program called Maryland Access to Care. DATA COLLECTION/EXTRACTION METHODS: Medicaid claims and hospital discharge ICD-9-CM codes were used to define hospitalization for ruptured and nonruptured appendicitis. Linear regression was used to model trends. Logistic regression was used to model the probability of ruptured appendicitis. PRINCIPAL FINDINGS: Among the 374 Medicaid inpatient claims for appendicitis, 37 percent were for ruptured appendicitis. Among the 5,141 hospital discharges for appendicitis, 30 percent were for ruptured appendicitis. Using Medicaid claims data, the probability of ruptured appendicitis was inversely related to age (OR = 0.86, 95% CI 0.81-0.91), white race (OR = 0.35, 95% CI 0.17-0.71) and preventive care visits (OR = 0.19, 95% CI 0.05-0.77). Using hospital discharge data, age (OR = 0.91, 95% CI 0.90-0.93) and female gender (OR = 0.87, 95% CI 0.77-0.99) were significant covariates. Insurance-related covariates were not significant in multivariate models addressing the probability of ruptured appendicitis. CONCLUSIONS: During a period of rapid managed care growth, insurance type was not associated with an increased risk of ruptured appendicitis among children in this geographic area. Age, female gender, and the number of preventive care visits are inversely related to the risk of ruptured appendix among children. The protective effect of preventive care visits suggests that a primary care relationship facilitates access to care, thus reducing delay in the management of appendicitis.

Plan characteristics and SSI enrollees' access to and quality of care in four TennCare MCOs.

OBJECTIVE: To assess hypotheses about which managed care organization (MCO) characteristics affect access to care and quality of care--including access to specialists, providers' knowledge about disability, and coordination of care--for people with disabilities. DATA SOURCES/STUDY SETTING: Survey of blind/disabled Supplemental Security Income (SSI) enrollees in four MCOs serving TennCare, Tennessee's Medicaid managed care program, in Memphis, conducted from 1998 through spring 1999. STUDY DESIGN: We compared enrollee reports of access and quality across the four MCOs using regression methods, and we use case study methods to assess whether patterns both within and across MCOs are consistent with the hypotheses. DATA COLLECTION: We conducted computer-assisted telephone surveys and used regression analysis to compare access and quality controlling for enrollee characteristics. PRINCIPAL FINDINGS: Although the four MCOs' characteristics varied, access to providers, coordination of care, and access to some services were generally similar across MCOs. Enrollees in one plan, the only MCO with a larger provider network and that paid physicians on a fee-for-service basis, reported their providers were more knowledgeable, and they had more secondary preventive care visits. Differences found in access to specialists and delays in approving care appear to be unrelated to characteristics reported by the MCOs, but instead may be related to how tightly utilization is reviewed. CONCLUSIONS: Plan networks, financial incentives, utilization management methods, and state requirements are important areas for further study, and, in the meantime, ongoing monitoring of SSI enrollees in each MCO may be important for detecting problems and successes.

Coping with the changing state of dental managed care.

About 58 percent of the American population has some type of managed dental care that pays for some, not all, dental care needs. Unlike the medical profession, the dental profession has not been devoured by managed care, but there is no question that managed care plans are here to stay. The various types of managed care programs are changing every day. The trend is for DHMOs and dental indemnity programs to decrease, DPPOs and dental referral programs to increase and dental reimbursement programs to grow slowly as more organizations become aware of their benefits. Plans vary from excellent to poor in their service to patients and their dentists. We dentists must learn to live with them and to educate our patients about the advantages and disadvantages of each. I am pleased to observe that fee-for-service dentistry, although challenged, is still very alive and strong and serving the public with the same high quality and freedom of choice for which American dentistry has always been known.

Misunderstanding of asthma controller medications: association with nonadherence.

OBJECTIVE: Nonadherence to regular inhaled anti-inflammatory medication use is a frequent contributor to poor control of persistent asthma and may result from misunderstanding of the preventive role of such medications. This study's aims are to 1) test the hypothesis that misunderstanding is associated with decreased adherence to its daily use and 2) identify factors associated with increased risk of misunderstanding. STUDY DESIGN: A sample of parents of children with asthma insured by Medicaid and enrolled in managed care programs in Northern California, Washington, and Massachusetts were interviewed by telephone. This analysis focused on the subset that reported having an inhaled anti-inflammatory medication and whose medication use and symptom frequency in the 2 weeks before the interview suggested persistent asthma. Misunderstanding of the role of inhaled anti-inflammatory medication was defined as identifying it as being for treatment of symptoms after they begin and not for prevention of symptoms before they start. RESULTS: A total of 1663 parents of children with asthma (63% response rate) were interviewed. Of those, 571 subjects (34%) reported use of an inhaled anti-inflammatory medication and met our criteria for persistent asthma. Among those with persistent asthma, 23% (131 parents) misunderstood the role of their child's inhaled anti-inflammatory. Misunderstanding of inhaled anti-inflammatory medication was associated with decreased adherence to its daily use (odds ratio [OR] 0.18, 95% confidence interval [CI], 0.11-0.29). The risk for misunderstanding was lower if the patient had seen a specialist (OR 0.42, 95% CI, 0.24-0.75) or had graduated high school (OR=0.54, 95% CI, 0.34-0.84). CONCLUSION: Misunderstanding of the role of inhaled anti-inflammatory medication is associated with reduced adherence to its daily use.

HEDIS performance trends in Medicare managed care.

The authors analyzed performance trends between 1996 and 1998 for health plans in the Medicare managed care program. Four measures from the Health Employer Data and Information Set (HEDIS) were used to track performance changes: adult access to preventive/ambulatory health services, beta blocker treatment following heart attacks, breast cancer screening, and eye exams for people with diabetes. Using a cohort analysis at the health plan level, statistically significant improvements in performance rates were observed for all measures. Health plans exhibiting relatively poor performance in 1996 accounted for the largest share of overall improvement in these measures across years.

Oral corticosteroid use among children in TennCare.

BACKGROUND: Lack of information about medication effects and use in children is a long-standing and troublesome policy issue. Documenting patterns of use for medications with potential for suboptimal use and adverse effects, such as oral corticosteroids, would be useful. OBJECTIVE: To describe the use of oral corticosteroids among children enrolled in TennCare, Tennessee's managed care program for Medicaid enrollees and uninsured individuals. DESIGN: A retrospective cohort study. DRUG EXPOSURE: Children enrolled in TennCare who had prescriptions filled in their name for oral corticosteroids during 1998 were identified. Descriptive information included age, race, sex, and county of residence. We identified possible indications for corticosteroid use for new users by searching encounter files for encounters temporally related to the index prescription. Subsequent use of corticosteroids was measured in the 365 days after the index prescription. RESULTS: Of 400 724 children continuously enrolled in TennCare during the study period, 29 362 (7327 per 100 000) children had a prescription filled for an oral corticosteroid. Steroid prescription filling was more common among young children and male children and less common among black children. Children in rural counties had oral corticosteroid prescriptions filled at a higher rate than children residing in urban counties. Nearly 75% of corticosteroid users filled only 1 prescription during the study period; 1319 children filled 4 or more prescriptions. Asthma was the most common indication for oral corticosteroid use (16%), whereas 1 in 5 users (22%) had an unknown indication for oral corticosteroid use. CONCLUSIONS: A large number of children enrolled in TennCare had a prescription for oral corticosteroids filled in 1998. Further population-based studies describing the development of adverse effects in users of corticosteroids would be important.

Combining state administrative databases and provider records to assess the quality of care for children enrolled in Medicaid.

Our objective was to assess the capability of state administrative health care databases to evaluate the quality of immunization rates for a Medicaid managed care population. Data on 5599 2 year olds were obtained from a Medicaid claims database, a health department database, and the records of the children's assigned providers. The study was conducted on 1 managed care program in 1 state. Test performance ratio analyses were used to assess the relative accuracy and contribution of each source of administrative data. We found that of the 67,188 doses needed, 45,511 (68%) were documented as administered per at least 1 of the data sources. Medicaid claims data alone accounted for 18% of immunized children, while health department data used by itself accounted for 12%. Together, these 2 sources identified 34% of immunized children. Large administrative databases, such as Medicaid claims and data from a health department, while valuable sources of information on quality, may underestimate outcomes such as immunization rates. Assessments of the quality of health care should rely on a combination of administrative data and providers' records as sources of information.

Comparison of cesarean section rates in fee-for-service versus managed care patients in the Ohio Medicaid population, 1992-1997.

OBJECTIVE: To examine changes over time in the cesarean section rates for fee-for-service (FFS) beneficiaries versus enrollees of managed care programs (MCPs) in the Ohio Medicaid population. STUDY DESIGN: Cross-sectional study using linked Ohio birth certificates and Medicaid files. PATIENTS AND METHODS: Study patients were Medicaid-enrolled residents of urban counties who had singleton, live births from 1992 through 1997 (n = 86,459). Changes in primary and repeat cesarean section rates were analyzed in the FFS and MCP groups. The test of homogeneity of odds ratios was used to measure the statistical difference between unadjusted odds ratios. Logistic regression analysis was conducted to adjust for risk factors. RESULTS: From 1992 to 1997, the difference in the rates of primary and repeat cesarean sections between FFS and MCP patients decreased. The unadjusted odds ratio (OR) increased from 0.66 to 0.81 (P = .06) for primary cesarean sections and from 0.67 to 1.04 (P = .03) for repeat cesarean sections; this indicated that the likelihood of undergoing a cesarean section increased over time for MCP enrollees compared with FFS beneficiaries. The results of the multivariate analysis indicated that the interaction term of payment source by year was not significant for primary cesarean sections (adjusted OR = 0.93; 95% confidence interval = 0.83, 1.04), but was highly significant for repeat cesarean sections (adjusted OR = 0.53; 95% confidence interval = 0.44, 0.64). CONCLUSION: We observed a reduction in the difference between the rates of both primary and repeat cesarean sections in FFS and MCP patients over time. The reduction was not statistically significant for primary cesarean sections. For repeat cesarean sections, however, we observed a convergence of the rates for FFS and MCP patients.

Medication patterns for attention-deficit/hyperactivity disorder and comorbid psychiatric conditions in a low-income population.

The aims of this study were two-fold: (1) to describe the patterns of comorbid psychiatric diagnosis and psychotropic drug therapy for children enrolled in a Medicaid-managed care program and diagnosed with attention-deficit/hyperactivity disorder (ADHD) in 2000 and (2) to examine child and provider characteristics associated with psychotropic medication patterns for this population. Multivariate logistic regression models were used to examine correlates of stimulant and seven nonstimulant psychotropic medication classes (alpha-agonists, mood stabilizer/anticonvulsant, antianxiety, standard antipsychotic, atypical antipsychotic, and tricyclic antidepressant (TCA)/other antidepressant and selective serotonin reuptake inhibitor (SSRI) antidepressant). With the exception of conduct disorders (odds ratio, 1.22; 95% confidence interval, 1.06-1.40), comorbid disorders had a significant protective effect (odds ratio less than 1) on dispensing stimulants. After adjusting for covariates, stimulant dispensing was strongly correlated with the interactions of geographic region with race/ethnicity and provider type. Children residing in the upstate New York region had an approximately ten-fold greater chance of being dispensed a stimulant compared to similar children in New York City. Utilizing a mental health provider increased the chance of being dispensed a stimulant by factor of two for children from New York City of any race/ethnicity group. Models predicting nonstimulant drug dispensing were distinct from the stimulant model. After adjusting for covariates, nonstimulant psychotropic medication dispensing was correlated with clinical factors, including comorbid disorder category and use of a mental health provider, as well as notable sociodemographic factors. Complex psychotropic medication and comorbid psychiatric disorder patterns were evident for this low-income population of children with ADHD. The roles of clinical, patient, and provider factors need to be better understood to explain these patterns of stimulant and nonstimulant psychotropic medications dispensed.
