Ethics in public health research: a research protocol to evaluate the effectiveness of public-private partnerships as a means to improve health and welfare systems worldwide.
Public-private partnerships have become a common approach to health care problems worldwide. Many public-private partnerships were created during the late 1990s, but most were focused on specific diseases such as HIV/AIDS, tuberculosis, and malaria. Recently there has been enthusiasm for using public-private partnerships to improve the delivery of health and welfare services for a wider range of health problems, especially in developing countries. The success of public-private partnerships in this context appears to be mixed, and few data are available to evaluate their effectiveness. This analysis provides an overview of the history of health-related public-private partnerships during the past 20 years and describes a research protocol commissioned by the World Health Organization to evaluate the effectiveness of public-private partnerships in a research context.

The practitioner's dilemma: can we use a patient's race to predict genetics, ancestry, and the expected outcomes of treatment?
Recent research has identified genetic traits that can be used in a laboratory setting to distinguish among global population groups. In some genetic analyses, the population groups identified resemble groups that are historically categorized as "races." On the basis of these associations, some researchers have argued that a patient's race can be used to predict underlying genetic traits and from these traits, the expected outcomes of treatment. Others have questioned the use of race in this way, arguing that racially defined groups are so heterogeneous that predictions of individual characteristics derived from group averages are bound to be problematic. Practitioners today face the dilemma of translating this scientific debate into clinical decisions made 1 patient at a time. Is it or is it not appropriate to use a patient's self-identified "race" to help decide treatment? In contrast to the global population groups identified by genetic studies, the U.S. population has experienced substantial genetic admixture over time, weakening our ability to distinguish groups on the basis of meaningful genetic differences. Nonetheless, many researchers have suggested that these differences are still sufficient to identify racially specific uses for pharmaceutical and other treatments. A review of recent research on the treatment of hypertension and congestive heart failure finds that race-specific treatments of this type carry a substantial risk for treating patients--black or white--inappropriately, either by withholding a treatment that may be effective or by using a treatment that may be ineffective. Only by moving beyond historical concepts of "race" to examining a patient's individual socioeconomic, cultural, behavioral, and ancestral circumstances can a practitioner select the treatment that is most likely to be effective and in doing so, can best serve that patient's needs.

Listening to patients: cultural and linguistic barriers to health care access.
BACKGROUND AND OBJECTIVES: Full access to medical care includes cultural and linguistic access as well as financial access. We sought to identify cultural and linguistic characteristics of low-income, ethnic minority patients' recent encounters with health care organizations that impede, and those that increase, health care access. METHODS: We conducted four focus groups with ethnically homogeneous African American, Latino, Native American, and Pacific Islander patients. Study participants were "walked" through the stages of a medical encounter and asked to identify physician and staff behaviors that made the patient feel more comfortable (a surrogate for increasing access) and behaviors that made the patient feel less comfortable (a surrogate for decreasing access). RESULTS: African American and Native American patients in particular expressed overall satisfaction with their physicians' services. Patients from all groups saw nonphysician staff as frequently impeding access. Based on perceptions of negative stereotypes, Native American and Pacific Islander patients reported hostility toward physicians' efforts at prevention and patient education. CONCLUSIONS: For the ethnic minority patients in our study, most perceived that cultural impediments to access involved nonphysician staff. Closer collaborations between health care organizations and ethnic minority communities in the recruitment and training of staff may be needed to improve cultural and linguistic access to care.

Race/ethnicity and patient satisfaction. Using the appropriate method to test for perceived differences in care.
OBJECTIVE: To determine whether an established patient satisfaction scale commonly used in the primary care setting is sufficiently sensitive to identify racial/ethnic differences in satisfaction that may exist; to compare a composite indicator of overall patient satisfaction with a 4-item satisfaction scale that measures only the quality of the direct physician-patient interaction. DESIGN: Real-time survey of patients during a primary care office visit. SETTING: Private medical offices in a generally affluent area of northern California. PARTICIPANTS: Five hundred thirty-seven primary care patients selected at random from those entering a medical office. MAIN OUTCOME MEASURES: Patient satisfaction using 1) a composite, 9-item satisfaction scale (VSQ-9); and 2) a 4-item subset of that scale that measures only satisfaction with direct physician care. RESULTS: The 9-item, composite scale identified no significant difference in patient satisfaction between white and nonwhite patients, after controlling for patient demographics and other aspects of the visit. The 4-item, physician-specific scale indicated that nonwhite patients were less satisfied than white patients with their direct interaction with the physicians included in the study (P </=.01). CONCLUSIONS: Measurements of patient satisfaction that use multi-item, composite indicators should also include focused comparisons of satisfaction directly with the care provided by the physician. In measurements of patient satisfaction, patient race/ethnicity should be included as an explanatory variable. The results also confirm earlier findings that factors external to the direct physician-patient interaction can have substantial effects on patients' perceptions of that interaction.
