Racial disparities in the frequency of patient safety events: results from the National Medicare Patient Safety Monitoring System.

BACKGROUND: Although there is extensive evidence of racial disparities in processes and outcomes of medical care, there has been limited investigation of disparities in patient safety. OBJECTIVE: To determine whether there are racial disparities in the frequency of adverse events studied in the Medicare Patient Safety Monitoring System. DESIGN AND SUBJECTS: Abstraction of 102,623 randomly selected charts from hospital discharges of non-Hispanic white and black Medicare patients between January 1, 2004 and December 31, 2007 to assess frequency of patient safety events in 4 domains: general (pressure ulcers and falls), selected nosocomial infections, selected procedure-related adverse events, and adverse drug events due to anticoagulants and hypoglycemic agents. MEASURES: Racial disparities in risk of patient safety events, and differences in adverse event rates among hospital groups stratified by percentage of black patients. RESULTS: Blacks had higher adjusted risk than whites of suffering one of the measured nosocomial infections (1.34; 95% confidence interval, 1.17-1.55; P < 0.001) and one of the measured adverse drug events (1.29; 95% confidence interval, 1.19-1.40; P < 0.001). After adjustment for patient and hospital factors, patients in hospitals with the highest percentages of black patients were at increased risk of experiencing one of the measured nosocomial infections (1.9% vs. 1.5%; P < 0.001) and adverse drug events (8.7% vs. 7.8%; P < 0.01). CONCLUSIONS: Hospitalized blacks are at higher risk than whites of experiencing certain patient safety events. In addition, hospitals serving high percentages of black patients have higher risk-adjusted rates of selected patient safety events.

Opportunities to improve colorectal cancer screening in Connecticut through Medicare claims data.

Colorectal cancer represents a serious public-health problem in the United States, with important geographic differences and disparities of care evident in its detection and treatment. While effective screening tests exist, Connecticut lacks current data about rates of colorectal cancer screening. The Connecticut Department of Public Health commissioned Qualidigm, the federally designated Quality Improvement Organization, to conduct an analysis of 2008 fee-for-service Medicare claims data to determine screening rates. This article reports the findings of this analysis to increase awareness of opportunities for improvement in colorectal cancer screening and to highlight demographic and geographic variations that may require particular attention in Connecticut.

The Equity and Quality (EQual) Health-Care Project: A Connecticut Health Foundation initiative with Qualidigm.

In response to the growing incidence and prevalence of diabetes, quality and disparity of care concerns, and the increasing diversity of the US and Connecticut's populations, the Connecticut Health Foundation funded Qualidigm to implement the Equity and Quality (EQual) Health-Care Project. Now in its second full year, the EQualHealth-CareProject is helping eight primary-care practices in Connecticut improve the equity and quality of diabetes care through technology, education, and quality improvement.

A descriptive study of educational outreach to promote use of quality improvement tools in primary care private practice.

The objective of this study was to describe the experience of a Quality Improvement Organization (QIO) providing educational outreach to promote use of quality improvement (QI) tools in primary care private practice. Two QIO outreach workers conducted visits with physicians and targeted staff. Data were analyzed on physician demographics, visits, and use of QI tools using standard quantitative and qualitative methods. QIO staff frequently encountered difficulty in accessing physicians and administrative staff and reported many barriers to QI. Despite these challenges, outreach visits were associated with adoption of QI tools, and certain physician characteristics were associated with greater numbers of outreach visits and tools adopted. QIOs and other external parties who seek to improve quality of care in private practice primary care physician offices face challenges in gaining access to physicians and administrative personnel. Additional study is needed to better understand associations between physician characteristics, educational outreach visits, and adoption of QI tools.

Understanding barriers to participation in mammography by women with disabilities.

PURPOSE: The study purpose was to identify barriers to mammography screening among women with different disabilities and to suggest interventions to address barriers. METHODS: Forty-two women with self-reported disabilities, ages 40 to 69 years participated. They resided in 24 Connecticut towns, and most had a prior mammogram. Data were collected through six disability-specific focus groups from women with sensory, physical, psychiatric, and cognitive/intellectual impairments. Facilitator-conducted groups used a semistructured guide. Qualitative analysis applied an iterative coding process to generate themes and categories. RESULTS: We identified four themes (i.e., access, beliefs, social support, and comfort/ accommodations) and nine subthemes that characterized barriers. In all focus groups, women mentioned physical access and physical comfort/accommodations as types of barriers. Other major subthemes were communication and professional support. Women also described mammography facilitators. CONCLUSION: Despite frequent use of health care and personal strategies to facilitate mammography screening, women with disabilities reported barriers to getting mammograms. Findings suggest a multifaceted approach to address these barriers.

Reducing disparities in utilization of mamography: reaching dually eligible women in Connecticut.

This article describes a two-pronged intervention by the health care Quality Improvement Organization (QIO) for Connecticut to address the disparity in rates of mammography screening between women eligible for both Medicare and Medicaid (i.e., "dually eligible") and other Medicare beneficiaries. The interventions were directed beneficiaries. One intervention addressed information and access needs of the target population: an education session was followed by a mobile mammography van session at low-income housing sites in specific geographic areas. The second intervention was a culturally-sensitive direct mailing to dually eligible beneficiaries across the state. Implementation methods are described including: defining and identifying the target population; specifying the disparity; developing community collaboration; and testing the mail materials. Preliminary results of the education sessions and community testing of the direct mail materials generated information about the target population. Issues in implementation and analysis include: reaching the target population, building community relations, and developing design approaches to test the intervention.

A comprehensive evaluation of a diabetes quality improvement project in privately owned primary care practices that serve minority patients.

The authors conducted a diabetes quality improvement project in 5 privately owned primary care practices serving at least 25% minority patients. Interventions included group-specific and practice-specific training on an electronic patient registry, cultural competency practices and tools, and selected quality improvement strategies. The authors conducted a comprehensive evaluation involving quantitative and qualitative data to assess project impact. Although overall clinical performance did not improve over the 14- to 20-month project time frame, other practice structural characteristics and processes did show improvement: successful implementation of the registry and clinician reminders in all practices, institution of team care and patient reminders in 4 practices, and collection of patient race/ethnicity data in 4 practices. These results highlight the difficulty of bringing about clinical improvement in this subset of practices and also the importance of conducting comprehensive evaluations to fully understand and interpret multicomponent quality improvement projects.

Hospital-acquired pressure ulcers: results from the national Medicare Patient Safety Monitoring System study.

OBJECTIVES: To determine the national and state incidence levels of newly hospital-acquired pressure ulcers (PUs) in Medicare beneficiaries and to describe the clinical and demographic characteristics and outcomes of these individuals. DESIGN: Retrospective secondary analysis of the national Medicare Patient Safety Monitoring System (MPSMS) database. SETTING: Medicare-eligible hospitals across the United States and select territories. PARTICIPANTS: Fifty-one thousand eight hundred forty-two randomly selected hospitalized fee-for-service Medicare beneficiaries discharged from the hospital between January 1, 2006, and December 31, 2007. MEASUREMENTS: Data were abstracted from the MPSMS, which collects information on multiple hospital adverse events. RESULTS: Of the 51,842 individuals in the MPSMS 2006/07 sample, 2,313 (4.5%) developed at least one new PU during their hospitalization. The mortality risk-adjusted odds ratios were 2.81 (95% confidence interval (CI) = 2.44-3.23) for in-hospital mortality, 1.69 (95% CI=1.61-1.77) for mortality within 30 days after discharge, and 1.33 (95% CI = 1.23-1.45) for readmission within 30 days. The hospital risk-adjusted main length of stay was 4.8 days (95% CI = 4.7-5.0 days) for individuals who did not develop PUs and 11.2 days (95% CI = 10.19-11.4) for those with hospital-acquired PUs (P < .001). The Northeast region and Missouri had the highest incidence rates (4.6% and 5.9%, respectively). CONCLUSION: Individuals who developed PUs were more likely to die during the hospital stay, have generally longer hospital lengths of stay, and be readmitted within 30 days after discharge.

Challenges in recruiting minority-serving private practice primary care physicians to a quality improvement project.

The objectives of this study were the following: (1) describe one organization's experience with recruiting minority-serving private practice primary care physicians to an ambulatory quality improvement (QI) project; (2) compare and contrast physicians who agreed to participate with those who declined; and (3) list incentives and barriers to participation. The authors identified eligible physicians by analyzing Medicare Part B claims data, a publicly available physician database, and office staff responses to telephone inquiries. The recruitment team had difficulty identifying, contacting, and recruiting eligible physicians. Solo practitioners and physicians who had lower scores on certain quality measures were more likely to participate. Barriers to participation were similar in all practices and included concerns about extra work, difficulty of change, and impact on office work flow. Commonly used incentives were offered but were not universally embraced. Additional work is required to refine the process of physician recruitment and to find more compelling incentives for QI.

Understanding patterns of change over time to improve mammography rates.

This retrospective cohort study determined trends and patterns of mammography rates during 5 years (1997-2001) among female Medicare beneficiaries ages 50 years and older in Connecticut to better understand changes in rates over time and to plan future interventions. Time series analysis and hierarchical Longitudinal logistic regression were used to assess changes over time. Mammography rates increased significantly during the 5-year period (p < .001). A cyclical pattern was observed for all age groups and counties, with dips and peaks in the spring and fall each year (average increase 8% per year), consistent with concentrated intervention activity at those times.

Improving the quality of preventive cardiovascular care provided by primary care physicians: insights from a US Quality Improvement Organization.

BACKGROUND: During 2000-03, Qualidigm, a US Quality Improvement Organization, conducted a project to improve the care received by elderly Medicare patients with coronary artery disease or cardiovascular risk factors. METHODS: We recruited primary care physicians in private practice in the state of Connecticut. Then, we identified approximately 30-50 patients per physician from the periods 1 January 2000 to 31 December 2000 and 1 November 2001 to 31 October 2002. We abstracted medical records to assess processes and outcomes of care, and we provided the physicians with performance data and a variety of practice-enhancing materials. The physicians utilized those materials that they perceived to be most helpful. RESULTS: We identified and recruited 974 primary care physicians to participate. Of these, 103 (10.6%) committed to participate, and 85 of the 103 completed the project. Among the intervention tools, physicians and their office personnel utilized personal digital assistants (PDAs) (36.5%) and patient education materials (34.1%) most commonly. Overall, quality of care improved for most physicians (mean quality score 62.0 to 67.8%, P < 0.001). However, not all improved, and most improvements were modest [mean absolute improvement in quality score 5.8%, standard deviation (SD) 6.8%]. CONCLUSIONS: Quality Improvement Organizations and others interested in improving outpatient quality of care face significant challenges in recruiting self-employed primary care physicians to quality improvement projects and in bringing about transformational change. Future primary care quality improvement projects should include careful assessments of practice-specific barriers, interventions that are linked to these barriers, and support of the practices on implementation.
