The effect of a combined influenza/pneumococcal immunization reminder letter.

BACKGROUND: The effect of a combined influenza and pneumococcal immunization reminder letter on increasing influenza and pneumococcal immunization rates, and the timeliness of receiving immunizations after receipt of a reminder letter, have not been examined. This study addresses these issues using a sample of new Medicare beneficiaries residing in Hawaii. METHODS: Newly enrolled Medicare beneficiaries in Hawaii from 25 September 1995 through 31 August 1996 were randomly assigned to one of three groups: Group 1, no letter (n=2144); Group 2, influenza immunization reminder letter only (n=2213); or Group 3, pneumococcal and influenza immunization reminder letter (n=2171). Health Care Financing Administration claims data were compared among groups. RESULTS: In Group 3, the influenza immunization rate increased 3.8 percentage points (n=87; p=0.017) compared with Group 1. The Group 3 pneumococcal immunization rate increased 3.5 percentage points (n=78; p<0.001) compared to Group 1 and 4.0 percentage points (n=86; p<0.001) compared to Group 2. Sixty-six beneficiaries in Group 3 received simultaneous pneumococcal and influenza immunizations, a significant difference compared to Group 1 or Group 2. Increases in immunizations were observed immediately following the reminder letters and the effect persisted for 5 to 7 weeks. CONCLUSIONS: The combination letter increased both influenza and pneumococcal immunization rates and the simultaneous administration of immunizations without detrimental effect to influenza immunization rates. A combined reminder letter is inexpensive and recommended as part of a multicomponent campaign for adult immunization.

Analysis of nationwide pharmacy charges per DRG.

The national hospital data used by the Health Care Financing Administration (HCFA) to construct the DRG-payment weights for the Medicare prospective-pricing system are analyzed and evaluated. The database represented a 20% sample of all Medicare hospital bills in 1981. Each record contained 96 bytes of data in 28 field elements, including DRG assignment, Standard Metropolitan Statistical Area code, length of stay (LOS), pharmacy charges, and total hospital charges. There was considerable variation in the relative weight of pharmacy charges to total ancillary charges among DRGs; however, the degree of variation appeared to be similar for both rural and urban hospitals. Examination of the pharmacy charges for the top-10 Medicare DRGs revealed that the median pharmacy charge per DRG was consistently less than the average pharmacy charge per DRG. Average pharmacy charges per DRG were generally 50% greater for urban hospitals than rural hospitals. Average and median LOS per DRG also differed substantially, and the LOS for urban hospitals was approximately 20% longer than it was in rural hospitals for all DRGs. The standards derived from the pharmacy-charge and LOS data used by HCFA in developing the DRG-payment weights should be used cautiously. The heterogeneity of these data confirms the imprecision in constructing these weights and the need to use median rather than average statistics as standards in use-review programs.

Finding relief from TEFRA cost limits.

The Tax Equity and Fiscal Responsibility Act (TEFRA) limits cost-per-case rate increases for inpatient care delivered by healthcare providers excluded from Medicare's prospective payment system. Costs beyond these limits normally are not reimbursed. Under certain circumstances, however, healthcare providers can receive reimbursement beyond TEFRA limits by petitioning for an adjustment from their fiscal intermediaries and the Health Care Financing Administration. Although the request process often is lengthy, providers who can thoroughly document substantial increases in the cost of delivering care due to extraordinary circumstances, significant wage, increases, or noncompatibility of cost-reporting periods may be granted relief in the form of a rate adjustment and, in rare cases, the assignment of a new base year.

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.

Strategies to encourage mammography use among women in senior citizens' housing facilities.

BACKGROUND: This randomized trial evaluated the impact of mammography-enhancing interventions implemented in 40 senior citizens' housing facilities in Pennsylvania and North Carolina. METHODS: After stratification of the facilities according to the socioeconomic status and racial backgrounds of their residents, they were randomly assigned to one of four groups to receive the following: 1) standard care--a Medicare mammography benefit flier; 2) education--the flier and a community education program; 3) access--the flier, mammography appointments, and transportation; 4) combined--all interventions. Telephone surveys, conducted prior to any intervention, identified mammography-eligible women, who were re-surveyed six months later to ascertain mammography use. RESULTS: Logistic regression analyses identified mammography intention, age, and the interaction between ever having had mammography and being in the combined intervention group to be significant predictors of mammography use at six months. However, no significant main effect was found for any of the interventions. CONCLUSIONS: These results suggest that the combination of community-directed mammography education and access to mammography appointments encourages mammography use primarily by women who are already predisposed to having mammography. However, individually targeted and tailored interventions may be needed to encourage mammography use among women who have never had mammography and/or express no intention of having it done.

Billing for physician services: a comparison of actual billing with CPT codes assigned by direct observation.

BACKGROUND: Little is known about the accuracy of family physicians' use of the Current procedural Terminology (CPT) coding scheme for office visits, despite increased administrative oversight of Medicare billing practices. In addition, the patient and visit characteristics that are associated with over- and undercoding are not well understood. METHODS: This study compared coding for evaluation and management (E&M) services billed for 3791 visits to 138 family physicians with the codes assigned by trained research nurses using direct observation. We calculated the degree to which the codes for E&M were concordant with the observer-assigned codes. Analysis of variance and logistic regression were used to examine the association of visit and patient characteristics with discordance between billed and observer-assigned CPT codes. RESULTS: Billing codes were concordant for 55% of encounters. Discordance was evenly distributed between under- and overcoding. Concordance of billed and observed codes was greatest for patients with indemnity insurance. Undercoding increased with longer visit length and a smaller percentage of the visit spent planning treatment. Overcoding was more common during visits with a greater percentage of time spent chatting, planning treatment, and delivering preventive services. CONCLUSIONS: Family physicians are generally accurate in their billing procedures. The findings on patient and visit characteristics associated with over- or undercoding may be used by practicing clinicians to enhance the accuracy of their coding and billing procedures.

Participation in health promotion programs by the rural elderly.

The Health Care Financing Administration (HCFA) funded a series of demonstration programs to learn about the implications of extending coverage for disease prevention/health promotion services to Medicare beneficiaries. This article examines the use of such services by a rural population under this demonstration program. Individuals enrolled in the demonstration were eligible for specific risk reduction interventions. They were enrolled in one of two groups: (1) a hospital-based group in which hospitals were paid a capitated fee for providing all services and (2) a physician-based group in which physicians were paid fee-for-service for providing each service. Chi-square tests of association as well as logistic regression models were used to assess whether eligibility for services, and use of services by those eligible, varied by group and by sociodemographic characteristics. Forty-one percent were eligible for a nutrition program, 11% for smoking cessation, 2% for alcohol counseling, and 7% for dementia/depression evaluations. Participation in the programs varied across the programs and within programs by gender, education, and group assignment. Older rural Americans will use some disease prevention/health promotion services if they are covered by Medicare. Use will be higher among those with more education. Rural beneficiaries are more likely to use preventive services if encouraged to do so by their doctors rather than by hospital-based programs.

Evaluation and management codes: from current procedural terminology through relative update commission to Center for Medicare and Medicaid Services.

BACKGROUND: Physicians should have a working knowledge of the process by which patient care codes are created and subsequently assigned values. The Society of Critical Care Medicine has representatives on the national committees that focus on code creation and definition and on assignment of relative value units. In addition, a better understanding of documentation requirements and the audit process will facilitate improved compliance and minimize liability. DISCUSSION: The authors discuss the current procedural terminology (CPT) process for defining care codes and the relative update commission (RUC) process for assigning values to those codes, with each code assigned a separate value in three separate categories. Steps for managing any concern or dispute about billing, denials, or an audit are subsequently addressed. Tenets of proper documentation are discussed, and some future developments are identified that are likely to affect critical care. CONCLUSION: Knowledge of the procedures by which care codes are defined and valued is necessary for using these codes properly, as well as for addressing needs unmet by existing codes. Preventing audits is the best approach to proper coding and billing, and documentation is key.

Pay for performance in commercial HMOs.

BACKGROUND: Pay for performance has increasingly become the subject of intense interest and debate, both of which have been heightened as the Centers for Medicare and Medicaid Services moves closer to adopting this approach for Medicare. Although many claims have been made for the effectiveness of this approach, the extent of its national penetration remains unknown. METHODS: We surveyed a sample of 252 health maintenance organizations (HMOs) (response rate, 96%) drawn from 41 metropolitan areas across the nation about use of pay for performance. We determined the prevalence of pay-for-performance programs, detailed the features of such programs, and examined the adoption of pay for performance as a function of the characteristics of both the health plans and markets. RESULTS: More than half the HMOs, representing more than 80% of persons enrolled, use pay for performance in their provider contracts. Of the 126 health plans with pay-for-performance programs, nearly 90% had programs for physicians and 38% had programs for hospitals. Use of pay for performance was statistically associated with geographic region, use of primary care providers (PCPs) as gatekeepers, use of capitation to pay PCPs, and whether the plans themselves received bonuses or penalties according to performance. CONCLUSIONS: Pay for performance is now commonly used by HMOs, especially those that are situated to assign responsibility for a particular patient to a PCP or medical group. As the design of Medicare with pay for performance moves forward, it will be important to leverage the early experience of pay for performance in the commercial market.

Mailed reminders for area-wide influenza immunization: a randomized controlled trial.

OBJECTIVE: To determine if mailed reminders would increase area-wide influenza immunization for persons aged 65 and older. DESIGN: A randomized, controlled trial. SETTING: Ten counties in Indiana. PARTICIPANTS: Using a Medicare database, 10,000 subjects were selected randomly from 10 counties in Indiana and randomized for the study. Using pre-established criteria, 4503 persons in the control group and 4508 in the intervention group were eligible for study. INTERVENTION: Intervention subjects received mailed reminders during the immunization season of 1995. MEASUREMENTS: Data from mailed surveys, Medicare claims, and phone calls were used to determine immunization rates. RESULTS: Of those surveyed who received immunization, only 63.4% filed a Medicare claim. Immunization rates were high in both groups but higher in the intervention group, 69.0% versus 64.2%. Age, presence of lung disease, assignment to the intervention group, presence of heart disease, and an age-sex interaction term were significantly and independently related to immunization. CONCLUSIONS: The Healthy People Year 2000 goal (60% immunization for persons 65 and older) was exceeded in this population. Medicare claims data do not reflect immunization rates accurately. Mailed reminders, an inexpensive intervention, increased immunization rates area-wide and have potential for cost savings.

The effects of framing and action instructions on whether older adults obtain flu shots.

The authors tested the effects of cues to action--messages intended to increase flu immunizations. North Dakota counties were randomly assigned to reminder letters, action letters, or no letters. Within the reminder-letter counties, Medicare recipients received either (a) a reminder from the state peer review organization (PRO) to obtain a flu shot or (b) a reminder from the PRO, framed either in terms of the loss associated with failing to get a shot or (c) the benefits associated with getting a shot. Within the action-letter counties, Medicare recipients leaned where and when to receive a flu shot. Reminder type failed to differentially affect the immunization rate (overall M = 24.5%). However, the action messages worked better (28.2%) than no message (19.6%).

The relationship of the value of outcome comparisons to the number of patients per provider.

PURPOSE: Monte Carlo methods were used to assess how the value of outcome comparisons depends on the number of patients per provider. METHODS: We simulated two patient data sets that have been used for well-known studies of outcome comparisons: mortality rates for coronary artery bypass surgeons from New York and Pennsylvania, and 30-day hospital mortality rates of Medicare patient from a national data set. In the simulated data sets, each surgeon or hospital provider was assigned a true or underlying probability of mortality. RESULTS: For the simulated CABG surgery data set, the underlying probability of mortality explained 30% of the variation in the observed mortality rate when there were 100 patients per physician, and 63% when there were 400 patients. The positive predictive value of using an observed mortality rate in the bottom 10% to identify a surgeon whose underlying probability of mortality was in the bottom 10% was 31% for 100 patients and 59% for 400 patients. The relationship between underlying and observed rates was weaker in the simulated Medicare data set with the same number of patients per provider. For a given data set, the amount of random variation in the observed rates of adverse outcomes among providers can be estimated with a simple equation. CONCLUSION: The results show that the assessment of provider outcomes may be greatly affected by random variation. An indication of the amount of random variation in a given data set can be obtained from the examples in this study and an equation for estimating random variation.

Data quality and DRGs: an assessment of the reliability of federal beneficiary discharge data in selected Manhattan hospitals.

New York County Health Services Review Organization (NYCHSRO), the physicians' professional standards review organization of Manhattan, examined whether diagnostic coding errors identified in Manhattan hospitals would affect reimbursement under a diagnostic-related group (DRG) method of financing inpatient services. A sampling of 1,027 Medicare and Medicaid cases representing discharges from 18 Manhattan hospitals during 1982 and 1983 revealed incorrect DRG assignment for 17.5% of patient record abstracts, but these appear to have been unsystematic rather than deliberate errors. The difference between estimated reimbursement based on original and reabstracted records was not statistically significant either in the aggregate or for specific hospitals. It is emphasized that while New York State's Prospective Hospital Reimbursement Methodology (in effect during the study period) is not solely dependent upon DRG's case-mix is one of several factors used to make adjustments to existing per diem rates. A key recommendation is that hospitals conduct internal monitorings with all involved departments to improve the quality of the data abstracting process.

Long-term cost effectiveness of early and sustained dual oral antiplatelet therapy with clopidogrel given for up to one year after percutaneous coronary intervention results: from the Clopidogrel for the Reduction of Events During Observation (CREDO) trial.

OBJECTIVES: This study sought to evaluate the long-term cost effectiveness of a clopidogrel loading strategy before percutaneous coronary intervention (PCI) followed by continued treatment for one year. BACKGROUND: The Clopidogrel for the Reduction of Events During Observation (CREDO) trial, a randomized trial of 2,116 patients, showed the effectiveness of antiplatelet therapy with clopidogrel 300 mg before PCI and 75 mg daily for one year afterward compared with placebo load and placebo days 29 to 365 in reducing the combined risk of death, myocardial infarction, and stroke. All patients received clopidogrel on days 1 to 28 and aspirin on days 1 to 365. METHODS: All hospitalizations were assigned a diagnosis-related group. Associated costs were estimated three ways (including professional costs): 1) Medicare costs, 2) MEDSTAT costs, and 3) blend with Medicare for those age > or = 65 years and MEDSTAT for those age <65 years. Clopidogrel 75 mg cost 3.22 dollars. Life expectancy in trial survivors was estimated using external data. Confidence intervals were assessed by bootstrap. RESULTS: The primary composite end point occurred in 89 (8.45%) clopidogrel patients and in 122 (11.48%) placebo patients (relative risk reduction [RRR] 26.9%; 95% confidence interval [CI] 3.9% to 44.4%). The number of life-years gained (LYG) with clopidogrel was 0.1526 (95% CI 0.0263 to 0.2838) using Framingham data and 0.1920 (95% CI 0.054 to 0.337) using Saskatchewan data. Average total costs were 664 dollars higher for the clopidogrel arm (95% CI -461 dollars to 1,784 dollars). The incremental cost-effectiveness ratios (ICERs) based on Framingham data ranged from 3,685 dollars/LYG to 4,353 dollars/LYG, with over 97% of bootstrap-derived ICER estimates below 50,000 dollars/LYG. The ICERs based on Saskatchewan data were 2,929 dollars/LYG to 3,460 dollars/LYG, with over 98% of estimates below 50,000 dollars/LYG. CONCLUSIONS: Platelet inhibition with clopidogrel loading before PCI followed by therapy for one year is highly cost effective.
