Racial and Ethnic Disparities in Care The Perspectives of Cardiologists

Background—Despite extensive documentation of racial and ethnic disparities in care, provider awareness of disparities has been thought to be low. To be effective, educational efforts for physicians must consider providers’ knowledge and beliefs about what causes disparities and what can be done about them. Methods and Results—We conducted a Web-based survey of 344 cardiologists to determine their level of awareness of disparities and views of underlying causes. Responses were assessed by means of 5-point Likert scales. Thirty-four percent of cardiologists agreed that disparities existed in care overall in the US healthcare system, and 33% agreed that disparities existed in cardiovascular care. Only 12% felt disparities existed in their own hospital setting, and even fewer, 5%, thought disparities existed in the care of their own patients. Despite this, most respondents rated the strength of the evidence about disparities as “very strong” or “strong.” Respondents identified many potential causes for disparities in care but were more likely to endorse patient and system level factors (eg, insurance status or adherence) rather than provider level factors. Conclusions—Cardiologists’ awareness of disparities in care remains low, and awareness is inversely proportional to proximity to their own practice setting.

Advancing the science of patient safety

Despite a decades worth of effort, patient safety has improved slowly, in part because of the limited evidence base for the development and widespread dissemination of successful patient safety practices. The Agency for Healthcare Research and Quality sponsored an international group of experts in patient safety and evaluation methods to develop criteria to improve the design, evaluation, and reporting of practice research in patient safety. This article reports the findings and recommendations of this group, which include greater use of theory and logic models, more detailed descriptions of interventions and their implementation, enhanced explanation of desired and unintended outcomes, and better description and measurement of context and of how context influences interventions. Using these criteria and measuring and reporting contexts will improve the science of patient safety.

What context features might be important determinants of the effectiveness of patient safety practice interventions

Background Differences in contexts (eg, policies, healthcare organisation characteristics) may explain variations in the effects of patient safety practice (PSP) implementations. However, knowledge of which contextual features are important determinants of PSP effectiveness is limited and consensus is lacking on a taxonomy of which contexts matter. Methods Iterative, formal discussions were held with a 22-member technical expert panel composed of experts or leaders in patient safety, healthcare systems, and methods. First, potentially important contextual features were identified, focusing on five PSPs. Then, two surveys were conducted to determine the context likely to influence PSP implementations. Results The panel reached a consensus on a taxonomy of four broad domains of contextual features important for PSP implementations: safety culture, teamwork and leadership involvement; structural organisational characteristics (eg, size, organisational complexity or financial status); external factors (eg, financial or performance incentives or PSP regulations); and availability of implementation and management tools (eg, training organisational incentives). Panelists also tended to rate specific patient safety culture, teamwork and leadership contexts as high priority for assessing their effects on PSP implementations, but tended to rate specific organisational characteristic contexts as high priority only for use in PSP evaluations. Panelists appeared split on whether specific external factors and implementation/management tools were important for assessment or only description. Conclusion This work can guide research commissioners and evaluators on the contextual features of PSP implementations that are important to report or evaluate. It represents a first step towards developing guidelines on contexts in PSP implementation evaluations. However, the science of context measurement needs maturing.

The Relationship Between Type of Mental Health Provider and Met and Unmet Mental Health Needs in a Nationally Representative Sample of HIV-positive Patients

This study examined mental health service utilization among a nationally representative sample of adults with HIV and psychiatric disorders or perceived need for mental health services. Data are from the HIV Cost and Services Utilization Study (HCSUS) mental health survey (n = 1489) conducted in 1997–1998. Most (70%) needed mental healthcare. Of these, 30% received no mental health services in the previous 6 months, 16% received services from general medical providers (GMPs) only, and 54% used mental health specialists. Clients with perceived need for care were more likely to receive any mental health services and services from mental health specialists (versus GMPs) than clients having mental disorders without perceived need. More patients using specialists versus GMPs received psychotherapeutic medications and psychiatric hospitalizations, controlling for psychiatric symptom severity. The findings underscore that the differential mental health service provision between specialists and GMPs existing in the general population also is present among persons with HIV.

Distance to Public Test Sites and HIV Testing

This article examines how proximity to the nearest publicly funded test site affects HIV testing. Using a sample of 5,361 Los Angeles County adults, multinomial logit models estimated simultaneously the likelihood of (1) obtaining an HIV test in the prior 2 years, and (2) testing in a private physicians office, a publicly funded medical clinic, or in a nonmedical setting, such as a bar or bathhouse. Low-income Los Angeles residents rely on publicly funded sites for HIV testing. When public sites are more distant, poor individuals are less likely to use them and less likely to get tested. Distance from public sites does not affect HIV testing among the nonpoor. To encourage HIV testing among the groups where HIV is growing fastest, public health agencies must keep the time and money costs of HIV testing low.

Bridging the gap between basic science and clinical practice: a role for community clinicians

BackgroundTranslating the extraordinary scientific and technological advances occurring in medical research laboratories into care for patients in communities throughout the country has been a major challenge. One contributing factor has been the relative absence of community practitioners from the US biomedical research enterprise. Identifying and addressing the barriers that prevent their participation in research should help bridge the gap between basic research and practice to improve quality of care for all Americans.MethodsWe interviewed over 200 clinicians and other healthcare stakeholders from 2004 through 2005 to develop a conceptual framework and set of strategies for engaging a stable cadre of community clinicians in a clinical research program.ResultsLack of engagement of community practitioners, lack of necessary infrastructure, and the current misalignment of financial incentives and research participation emerged as the three primary barriers to community clinician research participation. Although every effort was made to learn key motivators for engagement in clinical research from interviewees, we did not observe their behavior and self-report by clinicians does not always track with their behavior.ConclusionsA paradigm shift involving acknowledgement of the value of clinicians in the context of community research, establishment of a stable infrastructure to support a cohort of clinicians across time and research studies, and realignment of incentives to encourage participation in clinical research is required.

ZIP Code Correlates of HIV-Testing: A Multi-level Analysis in Los Angeles

In this study we examine how individuals’ residential areas relate to their HIV-testing, regardless of individuals’ characteristics. Data from a 1999 random probability sample of Los Angeles (LA) County adults (n = 5475) was used to conduct a multi-level analysis of HIV-testing among respondents in (1) all 233 ZIP codes and (2) the subset of regions with higher rates of higher-risk sex. Results showed that HIV-testing rates varied across individuals’ residential ZIP codes. Throughout LA and in higher-risk regions, residents of areas containing concentrations of African Americans were more likely to test for HIV than residents of White or Latino areas, regardless of individuals’ own race/ethnicity or the number of AIDS cases or testing sites in ZIP codes. However, residents of Latino areas were no more likely to test than residents of White areas. This is a concern because of increasing rates of HIV-infection among Latinos. We conclude that opportunities exist to increase testing in Latino higher-risk areas.

Reengineering the clinical research enterprise to involve more community clinicians

BackgroundThe National Institutes of Health has called for expansion of practice-based research to improve the clinical research enterprise.MethodsThis paper presents a model for the reorganization of clinical research to foster long-term participation by community clinicians.Based on the literature and interviews with clinicians and other stakeholders, we posited a model, conducted further interviews to test the viability of the model, and further adapted it.ResultsWe propose a three-dimensional system of checks and balances to support community clinicians using research support organizations, community outreach, a web-based registry of clinicians and studies, web-based training services, quality audits, and a feedback mechanism for clinicians engaged in research.ConclusionsThe proposed model is designed to offer a systemic mechanism to address current barriers that prevent clinicians from participation in research. Transparent mechanisms to guarantee the safety of patients and the integrity of the research enterprise paired with efficiencies and economies of scale are maintained by centralizing some of the functions. Assigning other responsibilities to more local levels assures flexibility with respect to the size of the clinician networks and the changing needs of researchers.

Patient safety in the nursing home: how nursing staff assess and communicate about change in condition.

Nursing homes must improve quality of care even as it becomes increasingly complex, and patient safety science may provide a helpful paradigm. Training materials are needed to build staff capacity for clinical assessment and communication, thereby improving care processes. Designed to develop curricular materials, this study used focus groups to determine how experienced nurses and aides assess and communicate about resident clinical changes. Four focus groups were conducted, and interviews were analyzed for themes in an iterative process by multidisciplinary team members. Staff reported that consistent caregiving enables detection of subtle clinical changes; aides further noted the importance of affective bonding. Aides and nurses alike regarded all clinical changes as potentially significant, while nursing staff lacked a consistent approach to assessment. Using a patient safety framework, structural changes and process elements were identified as important topics for further training to support clinical communication and improve resident and facility outcomes.

Off-premise alcohol sales policies, drinking, and sexual risk among people living with HIV.

Drinking among HIV-positive individuals increases risks of disease progression and possibly sexual transmission. We examined whether state alcohol sales policies are associated with drinking and sexual risk among people living with HIV. In a multivariate analysis combining national survey and state policy data, we found that HIV-positive residents of states allowing liquor sales in drug and grocery stores had 70% to 88% greater odds of drinking, daily drinking, and binge drinking than did HIV-positive residents of other states. High-risk sexual activity was more prevalent in states permitting longer sales hours (7% greater odds for each additional hour). Restrictive alcohol sales policies may reduce drinking and transmission risk in HIV-positive individuals.
