Qualitative research methods.

The use of rigorous qualitative research methods can enhance the development of quality measures, the development and dissemination of comparative quality reports, as well as quality improvement efforts. This paper describes how such methods have been and can be used, and identifies how to improve the use of such methods in studying quality of care. Focus groups and cognitive interviews are now a standard part of the development of valid and reliable survey instruments. They are particularly useful in developing surveys to gather data on the experiences and responses of patients and consumers to plans, services, and providers. These two methods have also been adapted and applied to improve the development and dissemination of comparative quality reports to consumers and other audiences, while key informant interviews and focus groups have been critical in the exploratory assessment of stakeholder responses to reports and their effects on consumers. Interviews have also been used to identify best practices found in health plans receiving high scores on the Consumer Assessment of Health Plans Surveys and measures of effectiveness in the Health Employer Data and Information Set. It would be valuable to widen the use of qualitative methods, especially structured observations, to document in detail the delivery of services designed to improve quality, so the implementation of complex processes can be more carefully measured and related to outcomes. The design and conduct of rigorous qualitative research takes a skilled and experienced team. Issues commonly faced in quantitative work must also be addressed in qualitative studies, including study design, specification of the unit of analysis, sampling, instrument design and administration, and, in particular, data analysis. It is especially critical that the analysis and interpretation process be deliberate and thorough to avoid the use of initial impression rather than detailed examination of the raw data.     

Consumer information and biased selection in the demand for coverage supplementing Medicare.

This study examines how the relationship between health insurance knowledge and the health status of health insurance consumers influences their decisions to purchase insurance coverage. Data from the federal Medicare health insurance program for the elderly in the United States are used. The basic Medicare program provides a limited amount of coverage for health care services obtained from any provider in the private fee-for-service (FFS) market. Beneficiaries of this program may choose to supplement the basic coverage which they receive by two mechanisms: either they may purchase private insurance designed to fill some of the gaps left by the federal program ('Medigap' policies), thereby remaining in the FFS market and preserving their choice of provider, or they may enroll in health maintenance organizations (HMOs), thereby leaving the FFS market and agreeing to use only those providers affiliated with the HMO, and in return receiving broader coverage at little additional out-of-pocket cost. The study was made possible by a unique data set which combines measures of beneficiary knowledge of Medicare coverage with measures of perceived health status, socio-economic characteristics, and insurance coverage choices for a sample of Medicare beneficiaries who participated in an educational workshop about their insurance coverage options. These data were used to estimate a multinomial logistic model of the determinants of insurance choices, where the options included the two listed above and a basic Medicare option. The study explicitly recognizes the interaction between insurance information and health status in health plan choice. These results show that knowledge of coverage does have a differential impact on the decision to purchase health insurance depending on health status. With a high level of knowledge, sicker beneficiaries are less likely to have basic Medicare alone, compared with HMOs or Medigap policies, while healthier beneficiaries are less likely to be enrolled in HMOs, compared with Medigap policies. This finding has important implications for the use of health status measures to adjust capitated payment formulas when knowledgable consumers have the option to enroll in HMOs or remain in the FFS environment. In the absence of health status adjusters for the HMO capitation payments, high levels of coverage knowledge may exacerbate inherent selection bias among these coverage options by healthier and sicker consumers of health insurance.     

Public–Private Collaboration in Health and Human Service Delivery: Evidence from Community Partnerships

The collaboration among public–private partnerships that applied to the Community Care Network (CCN) demonstration program of the Hospital Research and Educational Trust is examined. These partnerships link broad-based community coalitions with health and human service providers in efforts to improve community health and local service delivery. Although they willingly collaborated in identifying community health needs, coordinating services, and reporting to the community, partnership participants showed less alacrity in joining forces to reduce redundancy and increase efficiency. Such patterns suggest that organizations might best profit from working together on activities that maintain existing power relations and that have the potential to add prestige and attract new clients. Collaboration in these areas may be essential to building a foundation of trust that leads to future cooperation in more sensitive areas.

A GIS-based methodology for improving needle exchange service delivery

Background

A variety of legal, social and logistical factors can prevent individuals from accessing formal needle exchange programmes. One common solution to this problem is satellite exchange, which involves collaborating with people who already use an exchange to deliver needles and other supplies to those unable to access the exchange. While this approach can be very successful, one potential problem is that those most willing to deliver needles to their peers are often members of social networks that are already well connected with the needle exchange, leading to duplication of effort.In this paper we describe a simple and novel method for identifying groups of people who are demonstrably in need of improved access to needles, and for re-targeting efforts to meet the needs of those people. The method described was piloted at the Homeless Youth Alliance, San Francisco, USA, and further refined at Clean Needles Now, Los Angeles, USA.

Methods

People accessing needle exchange sites were asked to participate in a survey with two questions: “where were you and what time was it last time someone borrowed a needle from you?” and “where were you and what time was it last time you had to borrow a needle from someone else?” Responses were geocoded, and maps produced showing ‘hotspots’ where people were frequently finding themselves without needles.

Results

Satellite needle exchange was refined from an ad-hoc activity into one which focused on delivering needles to those with empirically demonstrable need. Maps produced in the process also proved valuable in discussions with local officials and other agencies about funding, as well as needle provision policy and practices.

Conclusion

We describe a method for rapidly assessing, describing, and responding to unmet and under-met need among injecting drug users. The method is particularly well-suited to organizations with extremely limited resources.
