Researcher and researched--community perspectives: toward bridging the gap.

In the process of initiating a new community-based research project, the authors wanted to understand the experiences of community members and researchers in community-based research projects and to develop guidelines to improve future projects. They conducted qualitative, key informant interviews with 41 people involved at all levels of community-based research projects in Seattle. Respondents were identified using a snowball sampling technique. More problems than successes were discussed by informants, including dissatisfaction with the focus of research, which some said is marked by a lack of cultural appropriateness and relevance. Power imbalances, lack of trust, and communication difficulties impeded collaboration. According to respondents, many problems could be avoided if the community were involved from the beginning in setting research priorities and developing and implementing interventions. Meaningful collaboration between communities and researchers is characterized by early involvement of communities, power sharing, mutual respect, community benefit, and cultural sensitivity.

Cost-effectiveness of combined outreach for the pneumococcal and influenza vaccines.

BACKGROUND: We conducted a cost-effectiveness analysis as part of a randomized, controlled trial of a community-based outreach initiative to promote the pneumococcal and influenza vaccines for people aged 65 years or older. METHODS: The analysis was based on primary data from the trial on the increase in vaccination rates and cost of the intervention, and published estimates of the effectiveness of the vaccines and cost of treatment. We performed partial stochastic analyses based on the confidence intervals (CIs) of the effectiveness of the intervention and of the vaccines. RESULTS: The cost-effectiveness ratio of the combined-outreach initiative as implemented was $35 486 per quality-adjusted life-year (QALY), whereas it was $53 547 per QALY for the pneumococcal vaccine and $130 908 per QALY for the influenza vaccine. In partial stochastic analyses, the quasi-CI of the combined-outreach initiative ranged from $15 145 to $152 311 per QALY. The cost-effectiveness ratio of the intervention targeted to people who had never received the pneumococcal vaccine or who had not received the influenza vaccine in the previous year was $11 771 per QALY, with a quasi-CI of $3330 to $46 095 per QALY. With the use of the projected cost of replicating the intervention, the cost-effectiveness ratio was $26 512 per QALY for the initiative as implemented and $7843 per QALY for a targeted initiative. CONCLUSIONS: The community-based outreach initiative to promote the pneumococcal and influenza vaccines was reasonably cost-effective. Further improvements in cost-effectiveness could be made by targeting the initiative or through lessons learned during the first year that would reduce the cost of the initiative in subsequent years.

Improving collaboration between researchers and communities.

Active collaboration between communities and researchers is critical to developing appropriate public health research strategies that address community concerns. To capture the perspectives of inner-city Seattle communities about issues in community-researcher partnerships, Seattle Partners for Healthy Communities conducted interviews with community members from the ethnically diverse neighborhoods of Central and Southeast Seattle. The results suggest that effective community-researcher collaborations require a paradigm shift from traditional practices to an approach that involves: acknowledging community contributions, recruiting and training minority people to participate in research teams, improving communication, sharing power, and valuing respect and diversity.

Increasing influenza and pneumococcal immunization rates: a randomized controlled study of a senior center-based intervention.

BACKGROUND: Immunizations decrease morbidity from influenza and pneumococcal infections. Immunization levels remain below desired levels despite clinic-based and public education efforts. This paper describes a randomized, controlled trial of a senior center-based program, which used peer-to-peer outreach to increase pneumococcal and influenza immunization rates among an urban senior population. METHODS: Seniors were randomized to intervention or control groups. The intervention group received educational brochures mailed with reply cards to report immunization status, telephone calls from senior volunteers to unimmunized participants, and computerized immunization tracking. Immunization rates were obtained before and after the intervention by self-report. RESULTS: Among participants without prior pneumococcal immunization, the pneumococcal immunization rate among the intervention group (52.0%; 95% CI = 46.6%-57.4%) was significantly higher than that of the control group (30.9%; 95% CI = 26.6%-35.2%) (rate ratio = 1.68; 95% CI = 1.40-2.03). Among those without influenza immunization in the prior year, significantly more (50.0%; 95% CI = 40.0%-60.0%) were immunized against influenza in the intervention group than in the control group (23.0%; 95% CI = 15.2%-33.3%) (rate ratio = 2.17; 95% CI = 1.42-3.31). Among those with influenza immunization in the prior year, the rate ratio was 1.04 (95% CI = 1.01-1.07). CONCLUSIONS: The intervention increased both influenza and pneumococcal immunization rates to high levels, suggesting that further progress in increasing adult immunization coverage is possible.
