Health plan decision making with new medicare information materials

OBJECTIVE: To examine the effect of providing new Medicare information materials on consumers' attitudes and behavior about health plan choice. DATA SOURCE: New and experienced Medicare beneficiaries who resided in the Kansas City metropolitan statistical area during winter 1998-99 were surveyed. More than 2,000 computer-assisted telephone interviews were completed across the two beneficiary populations with a mean response rate of 60 percent. STUDY DESIGN: Medicare beneficiaries were randomly assigned to a control group or one of three treatment groups that received varying amounts and types of new Medicare information materials. One treatment group received the Health Care Financing Administrations's pilot Medicare & You 1999 handbook, a second group received the same version of the handbook and a Medicare version of the Consumer Assessment of Health Plans (CAHPS) report, and a third treatment group received the Medicare & You bulletin, an abbreviated version of the handbook. PRINCIPAL FINDINGS: Results of the study suggest that the federal government's new consumer information materials are having some influence on Medicare beneficiaries' attitudes and behaviors about health plan decision making. Experienced beneficiary treatment group members were significantly more confident with their current health plan choice than control group members, but new beneficiaries were significantly less likely to use the new materials to choose or change health plans than control group members. In general the effects on confidence and health plan switching did not vary across the different treatment materials. CONCLUSIONS: The 1999 version of the Medicare & You materials contained a message that it is not necessary to change health plans. This message appears to have decreased the likelihood of using the new materials to choose or change plans, whereas other materials to which beneficiaries are exposed may encourage plan switching. Because providing more information to beneficiaries did not result in commensurate increases in confidence levels or rate of health plan switching, factors other than the amount of information, such as how the information is presented, may be more critical than volume.     

Beneficiaries' perceptions of new Medicare health plan choice print materials

This article presents findings from a study involving seven focus groups with aged and disabled Medicare beneficiaries in the Kansas City area regarding their impressions of a pilot version of the Medicare & You 1999 handbook and the Medicare Consumer Assessment of Health Plans Study (CAHPS) survey report. Beneficiaries generally had positive reactions to both booklets and viewed the handbook as an important reference tool. Based on the findings, we present policy recommendations for the development and dissemination of Medicare health plan information to beneficiaries.     

Reporting of CAHPS quality information to medicare beneficiaries

OBJECTIVES: To assess which Consumer Assessment of Health Plans (CAHPS) survey measures Medicare beneficiaries find the most meaningful, how beneficiaries and information intermediaries interpret different formats for presenting CAHPS information, and how beneficiaries have reacted to the CAHPS information included in the annual mailing to beneficiaries called Medicare & You 2000. DATA SOURCES: Fourteen focus groups of beneficiaries and State Health Insurance Assistance Program counselors, more than 200 cognitive interviews, and 122 mall-intercept interviews with beneficiaries were conducted from spring 1998 through winter 2000. STUDY DESIGN: In 1998 focus groups and cognitive interviews were conducted with Medicare beneficiaries and State Health Insurance Assistance Program counselors to determine which CAHPS measures to report to Medicare beneficiaries and how to report this information. In 1999 additional focus groups and mall-intercept interviews were conducted to determine which measures to include in Medicare & You 2000. To obtain feedback on the CAHPS information in Medicare & You 2000 additional focus groups were conducted in winter 2000. PRINCIPAL FINDINGS:Focus group participants indicated that getting the care they need quickly, having access to specialists, and communicating well with doctors were more important to them than nonmedical characteristics of plans. Most beneficiaries had problems interpreting quality information. Many misinterpreted star charts, and while bar charts appear easier to read, many beneficiaries still had trouble interpreting the information on these charts. Most beneficiaries did not consider quality information important to them and most were unaware of the availability of CAHPS information. CONCLUSIONS: Many challenges lie ahead in making quality information meaningful to Medicare beneficiaries. These challenges include increasing awareness of the existence of this information, educating beneficiaries about how this information can help in choosing a health plan, continuing to simplify reporting formats, assuring beneficiaries that this information comes from a credible source, and providing guidance to beneficiaries about how quality information can help with health care decisions.     

Effects of CAHPS health plan performance information on plan choices by New Jersey Medicaid beneficiaries

OBJECTIVE: To assess the effects of CAHPS health plan performance information on plan choices and decision processes by New Jersey Medicaid beneficiaries. DATA SOURCES/STUDY SETTING: The study sample was a statewide sample of all new Medicaid cases that chose Medicaid health plans during April 1998. The study used state data on health maintenance organization (HMO) enrollments and survey data for a subset of these cases. STUDY DESIGN: An experimental design was used, with new Medicaid cases randomly assigned to experimental or control groups. The experimental group received a CAHPS report along with the standard enrollment materials, and the control group did not. DATA COLLECTION: The HMO enrollment data were obtained from the state in June 1998, and evaluation survey data were collected from July to October 1998. PRINCIPAL FINDINGS: No effects of CAHPS information on HMO choices were found for the total sample. Further examination revealed that only about half the Medicaid cases said they received and read the plan report and there was an HMO with dominant Medicaid market share but low CAHPS performance scores. The subset of cases who read the report and did not choose this dominant HMO chose HMOs with higher CAHPS scores, on average, than did those in an equivalent control group. CONCLUSIONS: Health plan performance information can influence plan choices by Medicaid beneficiaries, but will do so only if they actually read it. These findings suggest a need for enhancing dissemination of the information as well as further education to encourage informed choices.     

Differences in the structure of CAHPS measures among the medicare fee-for-service, medicare managed care, and privately insured populations

OBJECTIVE: To confirm in a new population, the Medicare fee-for-service population, the factor structure previously found in two Consumer Assessment of Health Plans Study (CAHPS) field-test surveys with Medicare HMO and adult privately insured populations. DATA SOURCES: Primary data were collected in the fall of 1998. Survey responses from the Medicare Fee-for-Service CAHPS survey field test were compared to results from the Medicare HMO and adult privately insured field-test studies conducted in the fall of 1996. STUDY DESIGN: Respondents for the field-test survey were a random sample of Medicare beneficiaries in five states who had opted for the original Medicare plan (fee-for-service). DATA COLLECTION: Data were collected by a mailed survey with a telephone follow-up survey to those who did not return the mailed survey. PRINCIPAL FINDINGS: A confirmatory factor analysis in two different samples of Medicare fee-for-service beneficiaries provided basic support for a previously reported three-factor structure underlying the CAHPS reports and rating items: (1) quality of provider or staff communications; (2) timely access to quality health care; and (3) quality of plan administration. An exploratory factor analysis revealed a variant three-factor structure. CONCLUSION: Because of differences in the factor structures among the different populations discussed, caution needs to be exercised in any composite development, based on factor analysis or any other basis, by which cross-population comparisons will be made. Comparisons should only be made on composites representing stable structure across all populations concerned.     

Lessons learned from the National Medicare & You Education Program

In fall 1998 CMS implemented the National Medicare Education Program (NMEP) to educate beneficiaries about their Medicare program benefits; health plan choices; supplemental health insurance; beneficiary rights, responsibilities, and protections; and health behaviors. CMS has been monitoring the implementation of the NMEP in six case study sites as well as monitoring each of the information channels for communicating with beneficiaries. This article describes select findings from the case studies, and highlights from assessment activities related to the Medicare & You handbook, the toll-free 1-800-MEDICARE Helpline, Internet, and Regional Education About Choices in Health (REACH).     

Beneficiary survey-based feedback on new Medicare informational materials

In response to the Balanced Budget Act (BBA) of 1997, the Center for Medicare & Medicaid Services (CMS) initiated a massive information and education campaign to promote effective health plan decision-making. Early results suggest that the pilot version of the Medicare & You handbook and other new Medicare informational materials were viewed favorably overall. Despite their limitations, most beneficiaries found the information useful. The longer, more comprehensive materials were not perceived to be more useful than the shorter, less complicated version. Additional research is needed to determine which subgroups of beneficiaries may need more and, possibly less, information.     

How Do Proxy Responses and Proxy‐Assisted Responses Differ from What Medicare Beneficiaries Might Have Reported about Their Health Care?

OBJECTIVE: Assess proxy respondent effects on health care evaluations by Medicare beneficiaries. DATA SOURCE: 110,215 respondents from the nationally representative 2001 CAHPS((R)) Medicare Fee-for-Service Survey. STUDY DESIGN/DATA COLLECTION/EXTRACTION METHODS: We compare the effects of both proxy respondents and proxy assistance (reading, writing, or translating) on 23 "objective" report items and four "subjective" global measures of health care experiences using propensity-score-weighted regression. We assess whether proxy effects differ among spouses, other relatives, or nonrelatives. PRINCIPAL FINDINGS: Proxy respondents provide less positive evaluations of beneficiary health care experiences than otherwise similar self-reporting beneficiaries for more subjective global ratings (average effect of 0.21 standard deviations); differences are smaller for relatively objective and specific report items. Proxy assistance differences are similar, but about half as large. Reports from spouse proxy respondents are more positive than those from other proxies and are similar to what would have been reported by the beneficiaries themselves. Standard regression techniques may overestimate proxy effects in this instance. CONCLUSIONS: One should treat proxy responses to subjective ratings cautiously. Even seemingly innocuous reading, writing, and translation by proxies may influence answers. Spouses may be accurate proxies for the elderly in evaluations of health care.     

Do Mass Media Affect Medicare Beneficiaries’ Use of Diabetes Services?

BACKGROUND: Appropriate secondary preventive care for people with diabetes can reduce complications and premature death, yet many people with diabetes do not get these services. Mass media may influence individual health behavior. METHODS: In 1999, the West Virginia Medical Institute (WVMI) began a long-term radio and television campaign to educate West Virginia Medicare beneficiaries with diabetes about the importance of foot exams, eye exams, HbA1c testing, and influenza and pneumonia immunizations using messages with an "Ask your doctor about..." formula. To assess campaign efficacy, WVMI commissioned a telephone survey of 1500 randomly selected beneficiaries likely to have diabetes in two groups of counties with differing exposure to the messages. The survey asked whether the beneficiary had heard the messages and responded to them, by message topic. RESULTS: Nearly everyone (90%) in both survey groups said they had seen or heard the diabetes ads. However, high-exposure group members were about 1.2 times more likely to recall hearing most messages than low-exposure group members, and were 1.2 to 1.8 times more likely to say that they did what the messages suggested. CONCLUSIONS: Media campaigns with preventive health messages targeted to Medicare beneficiaries with diabetes can reach them and may induce appropriate responses.     

End of life Medicare and Medicaid expenditures for dually eligible beneficiaries

In 1995, combined Medicare and Medicaid spending in the last year of life for dually eligible beneficiaries was more than $40,000 per beneficiary. Medicaid's share, primarily for long-term care (LTC), constituted about 40 percent of the total. Beneficiaries under age 65, Black persons, and individuals who died in a hospital had higher than average expenditures. The vast majority (86 percent) received some form of supportive services (nursing home, home care, hospice services). It is critical that policy deliberations consider both acute and LTC use concurrently because of their extensive use by dually eligible beneficiaries, as well as the interaction of the two funding sources (Medicare and Medicaid) that cover them.     

Market Variations in Intensity of Medicare Service Use and Beneficiary Experiences with Care

Objective

Examine associations between patient experiences with care and service use across markets.

Data Sources/Study Setting

Medicare fee-for-service (FFS) and managed care (Medicare Advantage [MA]) beneficiaries in 306 markets from the 2003 Consumer Assessments of Healthcare Providers and Systems (CAHPS) surveys. Resource use intensity is measured by the 2003 end-of-life expenditure index.

Study Design

We estimated correlations and linear regressions of eight measures of case-mix-adjusted beneficiary experiences with intensity of service use across markets.

Data Collection/Extraction

We merged CAHPS data with service use data, excluding beneficiaries under 65 years of age or receiving Medicaid.

Principal Findings

Overall, higher intensity use was associated (p<.05) with worse (seven measures) or no better care experiences (two measures). In higher-intensity markets, Medicare FFS and MA beneficiaries reported more problems getting care quickly and less helpful office staff. However, Medicare FFS beneficiaries in higher-intensity markets reported higher overall ratings of their personal physician and main specialist. Medicare MA beneficiaries in higher-intensity markets also reported worse quality of communication with physicians, ability to get needed care, and overall ratings of care.

Conclusions

Medicare beneficiaries in markets characterized by high service use did not report better experiences with care. This trend was strongest for those in managed care.     

Measurement equivalence of the Consumer Assessment of Healthcare Providers and Systems (CAHPS<Superscript>®</Superscript>) Medicare survey items between Whites and Asians

Purpose

Asians report worse experiences with care than Whites. This could be due to true differences in care received, expectations about care, or survey response styles. We examined responses to the Consumer Assessment of Healthcare Providers and Systems (CAHPS^®) Medicare survey items by Whites and Asians, controlling for underlying level on the CAHPS constructs.

Methods

We conducted multiple group analyses to evaluate measurement equivalence of CAHPS Medicare survey data between White and Asian Medicare beneficiaries for CAHPS reporting composites (communication with personal doctor, access to care, plan customer service) and global ratings of care using pooled data from 2007 to 2011. Responses were obtained from 1,326,410 non-Hispanic Whites and 40,672 non-Hispanic Asians (hereafter referred to as Whites and Asians). The median age for Whites was 70, with 24 % 80 or older, and 70 for Asians, with 23 % 80 or older. Fifty-eight percent of Whites and 56 % of Asians were female.

Results

A model without group-specific estimates fit the data as well as a model that included 12 group-specific estimates (7 factor loadings, 3 measured variable errors, and 2 item intercepts): Comparative Fit Index = 0.947 and 0.948; root-mean-square error of approximation = 0.052 and 0.052, respectively). Differences in latent CAHPS score means between Whites and Hispanics estimated from the two models were similar, differing by 0.053 SD or less.

Conclusions

This study provides support for measurement equivalence of the CAHPS Medicare survey composites (communication, access, customer service) and global ratings between White and Asian respondents, supporting comparisons of care experiences between the two groups.

     

Enhancing influenza immunization. Postcard and telephone reminders and the challenge of immunization site shift

OBJECTIVE: To determine if postcard and telephone reminders increased the rate of influenza immunization of Medicare beneficiaries. DESIGN: Before and after trial (postcard reminders) with systematically allocated control group (telephone reminder intervention). SETTING: A semirural family practice residency program. PATIENTS AND OTHER PARTICIPANTS: All 475 noninstitutionalized persons older than 65 years who had received at least 1 office service in the previous 2 years. INTERVENTION: In September 1996, each of 475 patients received a postcard urging prompt influenza immunization. Those not responding within 1 month were systematically allocated either to a group receiving further telephone contact or to a control group. At the time of telephone contact, any offered information about influenza immunization received outside the Smoky Hill Family Practice Center, Salina, Kan, was recorded. MAIN OUTCOME MEASURES: We measured the percentage of change in practice-administered influenza immunizations compared with the baseline rate of the preceding 2 years; the difference in immunization rates between the telephone intervention group and controls; and the number of patients contacted by telephone who reported receiving influenza immunization at a site other than the Family Practice Center. RESULTS: Twenty-eight percent of patients who received a postcard obtained office influenza immunizations within 1 month, but no additional immunizations could be attributed to the telephone intervention. Thirty-five percent of patients contacted by telephone reported receiving influenza immunization at a site other than the Family Practice Center. CONCLUSIONS: The postcard intervention was associated with a significant increase in the office immunization rate. This increase may have been confounded by "site shift" in which individuals came to the office for an immunization that they might otherwise have received at other community sites.     

Comparing mortality and time until death for medicare HMO and FFS beneficiaries

OBJECTIVE: To compare adjusted mortality rates of TEFRA-risk HMO enrollees and disenrollees with rates of beneficiaries enrolled in the Medicare fee-for-service sector (FFS), and to compare the time until death for decedents in these three groups. DATA SOURCE: Data are from the 124 counties with the largest TEFRA-risk HMO enrollment using 1993-1994 Medicare Denominator files for beneficiaries enrolled in the FFS and TEFRA-risk HMO sectors. STUDY DESIGN: A retrospective study that tracks the mortality rates and time until death of a random sample of 1,240,120 Medicare beneficiaries in the FFS sector and 1,526,502 enrollees in HMOs between April 1, 1993 and April 1, 1994. A total of 58,201 beneficiaries switched from an HMO to the FFS sector and were analyzed separately. PRINCIPAL FINDINGS: HMO enrollees have lower relative odds of mortality than a comparable group of FFS beneficiaries. Conversely, HMO disenrollees have higher relative odds of mortality than comparable FFS beneficiaries. Among decedents in the three groups, HMO enrollees lived longer than FFS beneficiaries, who in turn lived longer than HMO disenrollees. CONCLUSIONS: Medicare TEFRA-risk HMO enrollees appear to be, on average, healthier than beneficiaries enrolled in the FFS sector, who appear to be in turn healthier than HMO disenrollees. These health status differences persist, even after controlling for beneficiary demographics and county-level variables that might confound the relationship between mortality and the insurance sector.     

The effect of the illness episode approach on Medicare beneficiaries'' health insurance decisions.

This article reports on a quasi-experimental test of the Illness Episode Approach (IEA), a new approach to providing Medicare beneficiaries with information about the financial consequences of alternative health care coverage decisions. Beneficiaries were randomly assigned to free, three-hour workshops, half using materials developed through application of the IEA, half using traditional comparative information on insurance options. Analysis of data collected before and after the workshops indicates that participants in the Illness Episode sessions were more likely to drop duplicative coverage, to spend less on premiums, and to report that their decisions to change coverage had met their expectations. The entire sample of workshop participants showed significant increases in knowledge of Medicare and their own insurance, as well as improved satisfaction with the cost of their health care coverage.     

How Do the Experiences of Medicare Beneficiary Subgroups Differ between Managed Care and Original Medicare?

Objective. To examine whether disparities in health care experiences of Medicare beneficiaries differ between managed care (Medicare Advantage [MA]) and traditional fee‐for‐service (FFS) Medicare. Data Sources. 132,937 MA and 201,444 FFS respondents to the 2007 Medicare Consumer Assessment of Health Care Providers and Systems (CAHPS) survey. Study Design. We defined seven subgroup characteristics: low‐income subsidy eligible, no high school degree, poor or fair self‐rated health, age 85 and older, female, Hispanic, and black. We estimated disparities in CAHPS experience of care scores between each of these groups and beneficiaries without those characteristics within MA and FFS for 11 CAHPS measures and assessed differences between MA and FFS disparities in linear models. Principal Findings. The seven subgroup characteristics had significant (p<.05) negative interactions with MA (larger disparities in MA) in 27 of 77 instances, with only four significant positive interactions. Conclusion. Managed care may provide less uniform care than FFS for patients; specifically there may be larger disparities in MA than FFS between beneficiaries who have low incomes, are less healthy, older, female, and who did not complete high school, compared with their counterparts. There may be potential for MA quality improvement targeted at the care provided to particular subgroups.     

Targeted mailed materials and the Medicare beneficiary: increasing mammogram screening among the elderly

OBJECTIVES: Older women have the highest breast cancer rates but are underscreened relative to their risk. Racial/ethnic minority women especially have low screening rates, often because of financial constraints. In response, Medicare introduced subsidized biennial mammogram benefits in 1991. This study examined the effect on mammography rates of an intervention that informed women about the Medicare benefit. METHODS: A list frame method of subject selection was used to select random samples of eligible women from the Health Care Financing Administration's master beneficiary file. Women were interviewed by telephone in 1991 (N = 917) before the targeted mailing and in 1993 (N = 922). One control and 2 treatment communities participated. RESULTS: Mammogram use increased significantly among minorities in the treatment groups. Among minorities who received the intervention, Black women were twice as likely (odds ratio = 1.97) and Hispanic women were more than twice as likely (odds ratio = 2.33) to undergo screening relative to their untreated cohorts. CONCLUSIONS: A targeted low-cost mailed intervention can help increase screening rates among elderly minority women. The Health Care Financing Administration should promote its benefits aggressively if it expects to reach its target--elderly beneficiaries.
