Results of the National Initiative for Cancer Care Quality: how can we improve the quality of cancer care in the United States?

PURPOSE: In 1999, the National Cancer Policy Board called attention to the quality of cancer care in the United States and recommended establishing a quality monitoring system with the capability of regularly reporting on the quality of care for patients with cancer. METHODS: Using data from a patient survey 4 years after diagnosis and review of medical records, we determined the percentage of stage I to III breast cancer and stage II to III colorectal cancer survivors in five metropolitan statistical areas (MSAs) across the United States who received recommended care specified by a comprehensive set of explicit quality measures. RESULTS: Two thousand three hundred sixty-six (63%) of 3,775 eligible patients responded to the survey, and 85% consented to have their medical records reviewed. Our final analytic sample (n = 1,765) included 47% of the eligible patients. Patients with breast and colorectal cancer received 86% of recommended care (95% CI, 86% to 87%) and 78% of recommended care (95% CI, 77% to 79%), respectively. Adherence to quality measures was less than 85% for 18 of the 36 breast cancer measures, and significant variation across MSAs was observed for seven quality measures. The percent adherence was less than 85% for 14 of the 25 colorectal cancer measures, and one quality measure demonstrated statistically significant variation across the MSAs. CONCLUSION: Initial management of patients with breast and colorectal cancer in the United States seemed consistent with evidence-based practice; however, substantial variation in adherence to some quality measures point to significant opportunities for improvement.

Early experience with pay-for-performance: from concept to practice.

CONTEXT: The adoption of pay-for-performance mechanisms for quality improvement is growing rapidly. Although there is intense interest in and optimism about pay-for-performance programs, there is little published research on pay-for-performance in health care. OBJECTIVE: To evaluate the impact of a prototypical physician pay-for-performance program on quality of care. DESIGN, SETTING, AND PARTICIPANTS: We evaluated a natural experiment with pay-for-performance using administrative reports of physician group quality from a large health plan for an intervention group (California physician groups) and a contemporaneous comparison group (Pacific Northwest physician groups). Quality improvement reports were included from October 2001 through April 2004 issued to approximately 300 large physician organizations. MAIN OUTCOME MEASURES: Three process measures of clinical quality: cervical cancer screening, mammography, and hemoglobin A1c testing. RESULTS: Improvements in clinical quality scores were as follows: for cervical cancer screening, 5.3% for California vs 1.7% for Pacific Northwest; for mammography, 1.9% vs 0.2%; and for hemoglobin A1c, 2.1% vs 2.1%. Compared with physician groups in the Pacific Northwest, the California network demonstrated greater quality improvement after the pay-for-performance intervention only in cervical cancer screening (a 3.6% difference in improvement [P = .02]). In total, the plan awarded 3.4 million dollars (27% of the amount set aside) in bonus payments between July 2003 and April 2004, the first year of the program. For all 3 measures, physician groups with baseline performance at or above the performance threshold for receipt of a bonus improved the least but garnered the largest share of the bonus payments. CONCLUSION: Paying clinicians to reach a common, fixed performance target may produce little gain in quality for the money spent and will largely reward those with higher performance at baseline.

Racial trends in the use of major procedures among the elderly.

BACKGROUND: Differences in the use of major procedures according to patients' race are well known. Whether national and local initiatives to reduce these differences have been successful is unknown. METHODS: We examined data for men and women enrolled in Medicare from 1992 through 2001 on annual age-standardized rates of receipt of nine surgical procedures previously shown to have disparities in the rates at which they were performed in black patients and in white patients. We also examined data according to hospital-referral region for three of the nine procedures: coronary-artery bypass grafting (CABG), carotid endarterectomy, and total hip replacement. RESULTS: Nationally, in 1992, the rates of receipt for all the procedures examined were higher among white patients than among black patients. The difference between the rates among whites and blacks increased significantly between 1992 and 2001 for five of the nine procedures, remained unchanged for three procedures, and narrowed significantly for one procedure. We examined rates of CABG, carotid endarterectomy, and total hip replacement in 158 hospital-referral regions (79 hospital-referral regions for black men and white men and 79 for black women and white women) with an adequate number of persons for each procedure. We found that in the early 1990s, whites had higher rates for these procedures than blacks in every hospital-referral region. By 2001, the difference between whites and blacks (both men and women) in the rates of these procedures narrowed significantly in 22 hospital-referral regions, widened significantly in 42, and were not significantly changed in the remaining hospital-referral regions. At the end of the study period, we found no hospital-referral region in which the difference in rates between whites and blacks was eliminated for men or women with regard to any of these three procedures. CONCLUSIONS: For the decade of the 1990s, we found no evidence, either nationally or locally, that efforts to eliminate racial disparities in the use of high-cost surgical procedures were successful.

Care in U.S. hospitals--the Hospital Quality Alliance program.

BACKGROUND: The Hospital Quality Alliance (HQA) is the first initiative that routinely reports data on hospitals' performance nationally. Heretofore, such data have been unavailable. METHODS: We used data collected by the Centers for Medicare and Medicaid Services on 10 indicators of the quality of care for acute myocardial infarction, congestive heart failure, and pneumonia. The main outcome measures were hospitals' performance with respect to each indicator and summary scores for each clinical condition. Predictors of a high level of performance were determined with the use of multivariable linear regression. RESULTS: A total of 3558 hospitals reported data on at least one stable measure (defined as information obtained from discharge data from at least 25 patients) during the first half of 2004. Median performance scores (expressed as the percentage of patients who satisfied the criterion) were at least 90 percent for 5 of the 10 measures but lower for the other 5. Performance varied moderately among large hospital-referral regions, with the top-ranked regions scoring 12 percentage points (for acute myocardial infarction) to 23 percentage points (for pneumonia) higher than the bottom-ranked regions. A high quality of care for acute myocardial infarction predicted a high quality of care for congestive heart failure but was only marginally better than chance at predicting a high quality of care for pneumonia. Characteristics associated with small but significant increases in performance included being an academic hospital, being in the Northeast or Midwest, and being a not-for-profit hospital. CONCLUSIONS: Analysis of data from the new HQA national reporting system shows that performance varies among hospitals and across indicators. Given this variation and small differences based on hospitals' characteristics, performance reporting will probably need to include numerous clinical conditions from a broad range of hospitals.

Error reporting and disclosure systems: views from hospital leaders.

CONTEXT: The Institute of Medicine has recommended establishing mandatory error reporting systems for hospitals and other health settings. OBJECTIVE: To examine the opinions and experiences of hospital leaders with state reporting systems. DESIGN AND SETTING: Survey of chief executive and chief operating officers (CEOs/COOs) from randomly selected hospitals in 2 states with mandatory reporting and public disclosure, 2 states with mandatory reporting without public disclosure, and 2 states without mandatory systems in 2002-2003. MAIN OUTCOME MEASURES: Perceptions of the effects of mandatory systems on error reporting, likelihood of lawsuits, and overall patient safety; attitudes regarding release of incident reports to the public; and likelihood of reporting incidents to the state or to the affected patient based on hypothetical clinical vignettes that varied the type and severity of patient injury. RESULTS: Responses were received from 203 of 320 hospitals (response rate = 63%). Most CEOs/COOs thought that a mandatory, nonconfidential system would discourage reporting of patient safety incidents to their hospital's own internal reporting system (69%) and encourage lawsuits (79%) while having no effect or a negative effect on patient safety (73%). More than 80% felt that the names of both the hospital and the involved professionals should be kept confidential, although respondents from states with mandatory public disclosure systems were more willing than respondents from the other states to release the hospital name (22% vs 4%-6%, P = .005). Based on the vignettes, more than 90% of hospital leaders said their hospital would report incidents involving serious injury to the state, but far fewer would report moderate or minor injuries, even when the incident was of sufficient consequence that they would tell the affected patient or family. CONCLUSIONS: Most hospital leaders expressed substantial concerns about the impact of mandatory, nonconfidential reporting systems on hospital internal reporting, lawsuits, and overall patient safety. While hospital leaders generally favor disclosure of patient safety incidents to involved patients, fewer would disclose incidents involving moderate or minor injury to state reporting systems.

Impact of 3-tier formularies on drug treatment of attention-deficit/hyperactivity disorder in children.

BACKGROUND: Expenditures for medications used to treat attention-deficit/hyperactivity disorder (ADHD) in children have increased rapidly. Many employers and health plans have adopted 3-tier formularies in an attempt to control costs for these and other drugs. OBJECTIVE: To assess the effect of copayment increases associated with 3-tier formulary adoption on use and spending patterns for ADHD medications for children. DESIGN AND SETTING: Observational study using quasi-experimental design to compare effects on ADHD medication use and spending for children enrolled as dependents in an employer-sponsored plan that made major changes to its pharmacy benefit design and a comparison group of children covered by the same insurer. The plan simultaneously moved from a 1-tier (same copayment required for all drugs) to a 3-tier formulary and implemented an across-the-board copayment increase. The plan later moved 3 drugs from tier 3 to tier 2. PARTICIPANTS: An intervention group of 20 326 and a comparison group of 15 776 children aged 18 years and younger. MAIN OUTCOME MEASURES: Monthly probability of using an ADHD medication; plan, enrollee, and total ADHD medication spending; and medication continuation. RESULTS: A 3-tier formulary implementation resulted in a 17% decrease in the monthly probability of using medication (P<.001), a 20% decrease in expected total medication expenditures, and a substantial shifting of costs from the plan to families (P<.001). Intervention group children using medications in the pre-period were more likely to change to a medication in a different tier after 3-tier adoption, relative to the comparison group (P = .08). The subsequent tier changes resulted in increased plan spending (P<.001) and decreased patient spending (P = .003) for users but no differences in continuation. CONCLUSIONS: The copayment increases associated with 3-tier formulary implementation by 1 employer resulted in lower total ADHD medication spending, sizeable increases in out-of-pocket expenditures for families of children with ADHD, and a significant decrease in the probability of using these medications.

Quality of care in for-profit and not-for-profit health plans enrolling Medicare beneficiaries.

BACKGROUND: For-profit health plans now enroll the majority of Medicare beneficiaries who select managed care. Prior research has produced conflicting results about whether for-profit health plans provide lower quality of care. OBJECTIVE: The objective was to compare the quality of care delivered by for-profit and not-for-profit health plans using Medicare Health Plan Employer Data and Information Set (HEDIS) clinical measures. RESEARCH DESIGN: This was an observational study comparing HEDIS scores in for-profit and not-for-profit health plans that enrolled Medicare beneficiaries in the United States during 1997. OUTCOME MEASURES: Outcome measures included health plan quality scores on each of 4 clinical services assessed by HEDIS: breast cancer screening, diabetic eye examination, beta-blocker medication after myocardial infarction, and follow-up after hospitalization for mental illness. RESULTS: The quality of care was lower in for-profit health plans than not-for-profit health plans on all 4 of the HEDIS measures we studied (67.5% vs 74.8% for breast cancer screening, 43.7% vs 57.7% for diabetic eye examination, 63.1% vs 75.2% for beta-blocker medication after myocardial infarction, and 42.1% vs 60.4% for follow-up after hospitalization for mental illness). Adjustment for sociodemographic case-mix and health plan characteristics reduced but did not eliminate the differences, which remained statistically significant for 3 of the 4 measures (not beta-blocker medication after myocardial infarction). Different geographic locations of for-profit and not-for-profit health plans did not explain these differences. CONCLUSION: By using standardized performance measures applied in a mandatory measurement program, we found that for-profit health plans provide lower quality of care than not-for-profit health plans. Special efforts to monitor and improve the quality of for-profit health plans may be warranted.

How patients' sociodemographic characteristics affect comparisons of competing health plans in California on HEDIS quality measures.

OBJECTIVE: To estimate effects of patient sociodemographic characteristics on differential performance within and between plans in a single market area on the HEDIS quality of care measures, widely used for purchasing and accreditation decisions in the United States. DESIGN: Using logistic regression, we modeled associations of age, sex, and zip-code-linked sociodemographic characteristics of health plan members with HEDIS measures of screening and preventive services. We calculated the impact of adjusting for these associations on measures of health plan performance. SETTING: Twenty-two California health plans provided individual-level HEDIS data and zip codes of residence for up to 2 years. PARTICIPANTS: 110 541 commercially insured health plan members. MAIN OUTCOME MEASURES: Ten HEDIS quality-of-care measures. RESULTS: Performance on quality measures was negatively associated with percent receiving public assistance in the local area (seven out of 10 measures), percent Black (three measures), and percent Hispanic (four measures), and positively associated with percent college educated (six measures), and percent urban (three measures), controlling for plan, while associations with percent Asian were positive for three measures and negative for one (P < 0.05 for six associations, P < 0.01 for four, P < 0.001 for 17). Associations were consistent across plans and over time. Adjustment for these characteristics changed rates for most plans and measures by <5 percentage points. CONCLUSIONS: Adjustment for socioeconomic case mix has little impact on the measured performance of most plans in California, but substantially affects a few. The impact of case mix on indicators should be considered when making comparisons of health plan quality.

Use of high-cost operative procedures by Medicare beneficiaries enrolled in for-profit and not-for-profit health plans.

BACKGROUND: It is widely believed that for-profit health plans are more likely than not-for-profit health plans to respond to financial incentives by restricting access to care, especially access to high-cost procedures. Until recently, data to address this question have been limited. METHODS: We tested the hypothesis that the rates of use of 12 common high-cost procedures would be lower in for-profit health plans than in not-for-profit plans. Using standardized Medicare HEDIS data on 3,726,065 Medicare beneficiaries 65 years of age or older who were enrolled in 254 health plans during 1997, we compared for-profit and not-for-profit plans with respect to rates of cardiac catheterization, coronary-artery bypass grafting, percutaneous transluminal coronary angioplasty, carotid endarterectomy, reduction of femur fracture, total hip replacement, total knee replacement, partial colectomy, open cholecystectomy, closed cholecystectomy, hysterectomy, and prostatectomy. We adjusted the comparisons for sociodemographic case mix and for characteristics of the health plans other than their tax status, including the plans' location. RESULTS: The rates of carotid endarterectomy, cardiac catheterization, coronary-artery bypass grafting, and percutaneous transluminal coronary angioplasty were higher in for-profit health plans than they were in not-for-profit health plans; the rates of use of other common costly operative procedures were similar in the two types of plan. After adjustment for enrollee case mix and other characteristics of the plans, the for-profit plans had significantly higher rates than the not-for-profit plans for 2 of the 12 procedures we studied and had lower rates for none. The geographic locations of the health plans did not explain these findings. CONCLUSIONS: Contrary to our expectations about the likely effects of financial incentives, the rates of use of high-cost operative procedures were not lower among beneficiaries enrolled in for-profit health plans than among those enrolled in not-for-profit health plans.

Differences in health-related quality of life and treatment preferences among black and white patients with end-stage renal disease.

BACKGROUND: Relatively little is known about racial differences in health-related quality of life (HRQL) among patients receiving dialysis for end-stage renal disease (ESRD) or how such differences may relate to preferences for renal transplantation. METHODS: We surveyed 1392 patients, ages 18-54 approximately 10 months after they initiated dialysis in 4 regions of the United States. The HRQL measures analyzed were overall health, emotional health, physical activity, energy level, social activity, and effect of ESRD on daily life. We also examined whether the measures of HRQL were associated with patients' preferences for renal transplantation by race. RESULTS: After adjustment for socioeconomic and clinical characteristics, Black women and men reported better overall health than White women and men, respectively. Black women reported higher energy levels than White women, and Black men reported less negative effects of ESRD on daily life compared to White men. Black men with high levels of physical activity were less likely to be certain about preferring a transplant than White men with similar levels of physical activity. CONCLUSIONS: Black patients receiving dialysis reported better HRQL than White patients, even after controlling for potential confounders. Racial differences in preferences for renal transplantation among men may be associated with their levels of physical activity.

Physicians' beliefs about racial differences in referral for renal transplantation.

BACKGROUND: Black patients with end-stage renal disease are much less likely than white patients to undergo renal transplantation, but previous research has shown that black patients are only slightly less likely to desire this procedure. A better understanding of physicians' views about racial differences in access to transplantation may help reduce disparities in care. METHODS: We surveyed 278 nephrologists in 4 US regions about quality of life and survival for black and white patients undergoing renal transplantation and reasons for racial differences in access to transplantation. We also surveyed 606 of their patients about their care. RESULTS: Physicians were less likely to believe transplantation improves survival for blacks than whites (69% versus 81%; P = 0.001), but similarly likely to believe it improves quality of life (84% versus 86%). Factors commonly cited by physicians as important reasons why blacks are less likely than whites to be evaluated for transplantation included patients' preferences (66%), availability of living donors (66%), failure to complete evaluations (53%), and comorbid illnesses (52%). Fewer physicians perceived patient-physician communication and trust (38%) or physician bias (12%) as important reasons. Black patients were less likely than white patients to report receiving some or a lot of information about transplantation (55% versus 74%; P = 0.006) when their physicians did not view patient-physician communication and trust as an important reason for racial differences in care. CONCLUSION: Nephrologists' views about the benefits of renal transplantation and reasons for racial differences in access to this procedure may affect how they present this treatment option to black and white patients.

Effects of pharmaceutical promotion on adherence to the treatment guidelines for depression.

OBJECTIVES: We sought to examine the impact of direct-to-consumer advertising (DTCA) and pharmaceutical promotion to physicians on the likelihood that (1) an individual diagnosed with depression received antidepressant medication and that (2) antidepressant medication was used for the appropriate duration. RESEARCH DESIGN AND SUBJECTS: A quasiexperimental design was used to examine treatment patterns of 30,621 depressed individuals whose insurance claims were included in the MarketScan database from 1997 through 2000. The main explanatory variables were spending on DTCA, detailing to physicians, and free samples for 6 antidepressant medications. RESULTS: Individuals diagnosed with depression during periods when class-level antidepressant DTCA spending was highest (cumulative spending more than US 18.5 million dollars) had 32% higher relative odds of initiating medication therapy compared with those diagnosed during periods when DTCA spending was lowest (P < 0.0001). Free samples of medications dispensed to physicians had no effect on odds of initiating antidepressant use. Class-level DTCA spending on antidepressants had a small positive effect on the duration of antidepressant use, whereas DTCA spending for the specific medication taken by an individual had no effect on treatment duration. Detailing spending at the class or product level had no significant effect on duration of treatment with an antidepressant medication. CONCLUSIONS: Our results suggest that DTCA of antidepressants was associated with an increase in the number of people diagnosed with depression who initiated medication therapy. DTCA was associated with a small increase in the number of individuals treated with antidepressants who received the appropriate duration of therapy. Promotion to physicians was not associated with either the initiation of treatment with an antidepressant or with the duration of therapy.

The effect of incentive-based formularies on prescription-drug utilization and spending.

BACKGROUND: Many employers and health plans have adopted incentive-based formularies in an attempt to control prescription-drug costs. METHODS: We used claims data to compare the utilization of and spending on drugs in two employer-sponsored health plans that implemented changes in formulary administration with those in comparison groups of enrollees covered by the same insurers. One plan simultaneously switched from a one-tier to a three-tier formulary and increased all enrollee copayments for medications. The second switched from a two-tier to a three-tier formulary, changing only the copayments for tier-3 drugs. We examined the utilization of angiotensin-converting-enzyme (ACE) inhibitors, proton-pump inhibitors, and 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins). RESULTS: Enrollees covered by the employer that implemented more dramatic changes experienced slower growth than the comparison group in the probability of the use of a drug and a major shift in spending from the plan to the enrollee. Among the enrollees who were initially taking tier-3 statins, more enrollees in the intervention group than in the comparison group switched to tier-1 or tier-2 medications (49 percent vs. 17 percent, P<0.001) or stopped taking statins entirely (21 percent vs. 11 percent, P=0.04). Patterns were similar for ACE inhibitors and proton-pump inhibitors. The enrollees covered by the employer that implemented more moderate changes were more likely than the comparison enrollees to switch to tier-1 or tier-2 medications but not to stop taking a given class of medications altogether. CONCLUSIONS: Different changes in formulary administration may have dramatically different effects on utilization and spending and may in some instances lead enrollees to discontinue therapy. The associated changes in copayments can substantially alter out-of-pocket spending by enrollees, the continuation of the use of medications, and possibly the quality of care.
