Trends in Colorectal Cancer Test Use in the Medicare Population, 1998–2005

BACKGROUND Colorectal cancer (CRC) screening has been covered under the Medicare program since 1998. No prior study has addressed the question of the completeness of CRC screening in the entire Medicare cohort. METHODS In 2008, CRC test-use rates were analyzed for the national fee-for-service Medicare population using Medicare enrollment and claims data from 1998 through 2005. Annual test-use rates were calculated for fecal occult blood testing, sigmoidoscopy, barium enema, and colonoscopy for each year by the demographic characteristics of enrollees. A current-in-Medicare rate was calculated to assess the percentage of enrollees with CRC testing according to recommended intervals. RESULTS Colonoscopy rates have increased every year since the introduction of CRC screening coverage. Test-use rates for all other test modalities have steadily decreased. The percentage of Medicare enrollees receiving appropriate tests has slowly increased. In 2005, 47% of enrollees aged >or=65 years and 33% of enrollees aged 50-64 years had claims indicating that they had been tested according to recommended intervals. CONCLUSIONS CRC test-use rates in the Medicare population are low. Disparities are apparent by age, race/ethnicity, gender, disability, income, and geographic residence. Much work remains to be done to increase testing to acceptable levels.

Data Sources for Measuring Colorectal Endoscopy Use Among Medicare Enrollees

Background: Estimates of colorectal cancer test use vary widely by data source. Medicare claims offer one source for monitoring test use, but their utility has not been validated. We compared ascertainment of sigmoidoscopy and colonoscopy between three data sources: self reports, Medicare claims, and medical records. Materials and Methods: The study population included Medicare enrollees residing in North Carolina (n = 561) who had participated in a telephone survey on colorectal cancer tests. Medicare claims were obtained for the 5 years preceding the survey (January 1, 1998 to December 31, 2002). Information about sigmoidoscopy and colonoscopy procedures conducted in physician offices were abstracted from medical records. Sensitivity, specificity, positive predictive value, negative predictive value, agreement, and κ statistics were calculated using the medical record as the gold standard. Agreement on specific procedure type and purpose was also assessed. Results: Agreement between claim and medical record regarding whether an endoscopic procedure had been done was high (over 90%). Agreement between self report and medical record and between self report and claim was good (79% and 74%, respectively). All three data sources adequately distinguished the type of procedure done. None of the data sources showed reliable levels of agreement regarding procedure purpose (screening or diagnostic). Conclusion: Medicare claims can provide accurate information on whether a patient has undergone colorectal endoscopy and may be more complete than physician medical records. Medicare claims cannot be used to distinguish screening from diagnostic tests. Recognizing this limitation, researchers who use Medicare claims to assess rates of colorectal testing should include both screening and diagnostic endoscopy procedures in their analyses.

The PEACE project: Identification of quality measures for hospice and palliative care

CONTEXT In 2008, the Centers for Medicare & Medicaid Services (CMS) required U.S. hospices to implement comprehensive quality improvement programs. CMS contracted with the Quality Improvement Organization in North and South Carolina to develop quality measures and instruments to assess hospice and palliative care quality. OBJECTIVES To develop a set of quality measures, with complete specifications, and data collection tools for use by hospice and palliative care providers in quality improvement. METHODS Quality measures were identified from: published literature, the National Quality Forum, CMS measures, the National Quality Measures Clearinghouse, and measures submitted by two national hospice organizations. Available data on the quality measures were gathered and pilot data were collected for measures with no available data. A Technical Expert Panel (TEP) rated quality measures on: importance, scientific soundness, feasibility and usability, using numeric scores for each dimension. Scores for quality measures were averaged across dimensions and across TEP members to identify measures for further development. RESULTS Of 174 measures identified, 88 were determined appropriate to the setting and were reviewed and rated by the TEP. Measures with overall scores ≥75th percentile (n = 23), measures with high importance scores (n = 7), measures for under-represented domains (n = 2), and process measures antecedent to TEP identified measures (n = 2), and were selected. CONCLUSIONS Specifications and data collection tools are available for 34 PEACE quality measures that were highly rated by experts in hospice and palliative care. Future research should assess the scientific soundness and responsiveness of these measures to quality improvement.

Impact of Distance to a Urologist on Early Diagnosis of Prostate Cancer Among Black and White Patients

PURPOSE We examined whether an increased distance to a urologist is associated with a delayed diagnosis of prostate cancer among black and white patients, as manifested by higher risk disease at diagnosis. MATERIALS AND METHODS North Carolina Central Cancer Registry data were linked to Medicare claims for patients with incident prostate cancer diagnosed in 2004 to 2005. Straight-line distances were calculated from the patient home to the nearest urologist. Race stratified multivariate ordinal logistic regression was used to examine the association between distance to a urologist and prostate cancer risk group (low, intermediate, high or very high/metastasis) at diagnosis for black and white patients while accounting for age, comorbidity, marital status and diagnosis year. An overall model was then used to examine the distance × race interaction effect. RESULTS Included in analysis were 1,720 white and 531 black men. In the overall cohort the high risk cancer rate increased monotonically with distance to a urologist, including 40% for 0 to 10, 45% for 11 to 20 and 57% for greater than 20 miles. Correspondingly the low risk cancer rate decreased with longer distance. On race stratified multivariate analysis longer distance was associated with higher risk prostate cancer for white and black patients (p = 0.04 and <0.01, respectively) but the effect was larger in the latter group. The distance × race interaction term was significant in the overall model (p = 0.03). CONCLUSIONS Longer distance to a urologist may disproportionally impact black patients. Decreasing modifiable barriers to health care access, such as distance to care, may decrease racial disparities in prostate cancer.

The PEACE Project Review of Clinical Instruments for Hospice and Palliative Care

BACKGROUND Hospice and palliative care organizations are expanding their use of standardized instruments and other approaches to measure quality. We undertook a systematic review and evaluation of published patient-level instruments for potential application in hospice and palliative care clinical quality measurement. METHODS We searched prior reviews and computerized reference databases from 1990 through February 2007 for studies of instruments relevant to physical, psychological, social, cultural, spiritual, or ethical aspects of palliative care, or measuring prognosis, function or continuity of care. Publications were selected for full review if they provided evidence of psychometric properties or practical application of an instrument tested in or appropriate for a hospice or palliative care population. Selected instruments were evaluated and scored for scientific soundness and potential application in clinical quality measurement. RESULTS The search found 1427 publications, with 229 selected for full manuscript review. Manuscripts provided information on 129 instruments which were evaluated using a structured scoring guide for psychometric properties. Thirty-nine instruments scoring near or above the 75th percentile were recommended. Most instruments covered multiple domains or focused on care for physical symptoms, psychological or social aspects of care. Few instruments were available to measure cultural aspects of care, structure and process of care, and continuity of care. CONCLUSION Numerous patient-level instruments are available to measure physical, psychological and social aspects of palliative care with adequate evidence for scientific soundness and practical clinical use for quality improvement and research. Other aspects of palliative care may benefit from further instrument development research.

Quality Measures for Hospice and Palliative Care: Piloting the PEACE Measures

BACKGROUND The Carolinas Center for Medical Excellence launched the PEACE project in 2006, under contract with the Centers for Medicare & Medicaid Services (CMS), to identify, develop, and pilot test quality measures for hospice and palliative care programs. OBJECTIVES The project collected pilot data to test the usability and feasibility of potential quality measures and data collection processes for hospice and palliative care programs. Settings/subjects: Twenty-two hospices participating in a national Quality Improvement Collaborative (QIC) submitted data from 367 chart reviews for pain care and 45 chart reviews for nausea care. Fourteen additional hospices completed a one-time data submission of 126 chart reviews on 60 potential patient-level quality measures across eight domains of care and an organizational assessment evaluating structure and processes of care. DESIGN Usability was assessed by examining the range, variability and size of the populations targeted by each quality measure. Feasibility was assessed during the second pilot study by surveying data abstractors about the abstraction process and examining the rates of missing data. The impact of data collection processes was assessed by comparing results obtained using different processes. RESULTS Measures shown to be both usable and feasible included: screening for physical symptoms on admission and documentation of treatment preferences. Methods of data collection and measure construction appear to influence observed rates of quality of care. CONCLUSIONS We successfully identified quality measures with potential for use in hospices and palliative care programs. Future research is needed to understand whether these measures are sensitive to quality improvement interventions.

Use of Electronic Documentation for Quality Improvement in Hospice

Little evidence exists about the use of electronic documentation (ED) in hospice and its relationship to quality improvement (QI) practices. The purposes of this study were to (1) estimate the prevalence of ED use in hospice, (2) identify organizational characteristics associated with use of ED, and (3) determine whether quality measurement practices differed based on documentation format (electronic vs nonelectronic). Surveys concerning the use of ED for QI practices and the monitoring of quality-related care and outcomes were collected from 653 hospices. Users of ED were able to monitor a wider range of quality-related data than users of non-ED. Quality components such as advanced care planning, cultural needs, experience during care of the actively dying, and the number/types of care being delivered were more likely to be documented by users of ED. Use of ED may help hospices monitor quality and compliance.

Trends and Racial Differences in the Use of Androgen Deprivation Therapy for Metastatic Prostate Cancer

CONTEXT Androgen deprivation therapy (ADT) is widely used to manage the symptoms of advanced prostate cancer and has been shown to slow the progression of the disease. Previous research investigating racial differences in the use of ADT has reported inconsistent findings. OBJECTIVES The purpose of this study was to assess use trends for ADT overall and by type (orchiectomy and luteinizing hormone-releasing hormone [LHRH] agonists) and the factors associated with time to receipt for metastatic prostate cancer. METHODS Data from the Surveillance, Epidemiology, and End Results (SEER) cancer registry and Medicare claims database were obtained for 5,273 men, aged 65 years and older and diagnosed with Stage IV prostate cancer during 1991-1999 from seven SEER regions. An accelerated failure time regression model with log-normal distribution was used to examine factors associated with mean time to receipt of ADT. RESULTS African-American men were less likely than white men to receive any ADT after diagnosis (P<0.001). Differences were noted in the time to receipt of ADT, with African-American men having a longer mean time to receipt of orchiectomy (time ratio [TR]=1.50; 95% confidence interval [CI]=1.03, 2.17) or LHRH agonist (TR=1.42; 95% CI=1.06, 1.89) than white men. CONCLUSION African-American men with metastatic prostate cancer were significantly less likely to receive ADT and, when treated, had a slightly longer time to receipt than white men, which has implications for patients and physicians involved in the palliative management of metastatic prostate cancer.

Seat Belt Use Laws: The Influence of Data on Public Opinion

Motor vehicle crashes are a major public health problem. Mandatory seat belt use laws capable of lessening the highway death and injury toll have recently received a great deal of public attention. Public opinions toward such laws were assessed in a representative sample of 410 North Carolina drivers. In our experimental design, subjects were randomly assigned to receive one of six types of data expressing the effectiveness of the proposed mandatory and the current voluntary policies. A comparison group received no data. Exposure to data about the effec tiveness of the proposed seat belt law was strongly predictive of policy preferences, though the specific type of data did not appear to have an influence. Additional characteristics predictive of policy preferences included attitudes toward other government regulations, beliefs about the effectiveness of seat belts, and personal seat belt use. The findings suggest that health educators need to continue to provide the public with data about potential safety regulations. Furthermore, health educators, to be more effective, should target information toward certain critical beliefs such as those about the relative effectiveness of a particular policy.

Quality improvement in hospice: adding a big job to an already big job?

Hospice organizations are adopting quality measurement and quality improvement (QI) practices to comply with the Medicare Conditions of Participation effective January 31, 2009. However, little is known about organizational best practices or specific needs during implementation. This study identified and described the barriers and facilitators to QI implementation in hospice. Using semistructured interviews with a national sample of key informants (n = 52) concerning facilitators and barriers to QI in hospice, 4 major themes emerged from the data regarding participants’ experiences and perceptions: (1) external factors constrain QI implementation; (2) internal factors limit capacity for QI; (3) research on best practices is limited; and (4) traditional QI may not be a good fit for hospice. Though challenging, participants provided recommendations that they believed would facilitate QI in hospice. Categorizing barriers and facilitators as within or outside an organization’s control may help organizations assess their capabilities and locate resources to address areas for improvement.
