Effective lay health worker outreach and media-based education for promoting cervical cancer screening among Vietnamese American women.

OBJECTIVES: We sought to promote cervical cancer screening among Vietnamese American women in Santa Clara County, Calif. METHODS: In 2001-2004, we recruited and randomized 1005 Vietnamese American women into 2 groups: lay health worker outreach plus media-based education (combined intervention) or media-based education only. Lay health workers met with the combined intervention group twice over 3 to 4 months to promote Papanicolaou (Pap) testing. We used questionnaires to measure changes in awareness, knowledge, and Pap testing. RESULTS: Testing increased among women in both the combined intervention (65.8% to 81.8%; P<.001) and media-only (70.1% to 75.5%; P<.001) groups, but significantly more in the combined intervention group (P=.001). Among women never previously screened, significantly more women in the combined intervention group (46.0%) than in the media-only group (27.1%) obtained tests (P<.001). Significantly more women in the combined intervention group obtained their first Pap test or obtained one after an interval of more than 1 year (became up-to-date; 45.7% to 67.3%, respectively; P<.001) than did those in the media-only group (50.9% to 55.7%, respectively; P=.035). CONCLUSIONS: Combined intervention motivated more Vietnamese American women to obtain their first Pap tests and to become up-to-date than did media education alone.

Community-based participatory research increases cervical cancer screening among Vietnamese-Americans.

Using community-based participatory research methods, a community-research coalition in Santa Clara County, California (SCC) conducted a quasi-experimental, controlled trial to increase Pap test receipt and to build community capacity among Vietnamese-American women. From 1999 to 2004, the Coalition planned and implemented an Action Plan with six components: multimedia campaign, lay health worker outreach, Vietnamese Pap clinic with patient navigation, registry and reminder system, continuing medical education for Vietnamese physicians, and restoring a Breast and Cervical Cancer Control Program site. Components were evaluated individually. Community-wide, cross-sectional telephone surveys of Vietnamese women in SCC (intervention community) and Harris County, Texas (comparison community) measured overall project impact. Receipt and currency of Pap tests increased significantly in the intervention compared with the comparison community. Community involvement, system changes, community and research capacity building, dissemination of results, and program sustainability were also demonstrated. Community-based participatory research is feasible and effective in Vietnamese-American communities.

Papanicolaou testing among Vietnamese Americans: results of a multifaceted intervention.

BACKGROUND: Vietnamese-American women have the highest incidence of cervical cancer of any ethnic group, and they underutilize Papanicolaou (Pap) tests. DESIGN: Development and implementation of a multifaceted intervention using community-based participatory research (CBPR) methodology and evaluated with a quasi-experimental controlled design with cross-sectional pre-intervention (2000) and post-intervention (2004) telephone surveys. Data were analyzed in 2005. SETTING: Santa Clara County, California (intervention community) and Harris County, Texas (comparison community). PARTICIPANTS: Vietnamese-American women aged 18 and older (n =1566 at pre-intervention and 2009 at post-intervention). INTERVENTION: A community-academic coalition developed and implemented six components: Vietnamese-language media campaign, lay health worker outreach, Vietnamese Pap clinic, patient registry/reminder system, restoration of a government-funded low-cost screening program, and continuing medical education for Vietnamese physicians. OUTCOME MEASURE: Pap test receipt. RESULTS: Overall response rate was 56%. Pap test receipt increased in the intervention (77.5% to 84.2%, p <0.001), but not in the comparison community (73.9% to 70.6%, p >0.05). In multivariate analyses, the intervention was associated with increased Pap test receipt (odds ratio [OR]=2.02, 95% confidence interval [CI]=1.37-2.99). Other factors associated with increased Pap testing included longer U.S. residence, having health insurance, having a regular site of care, having a respectful physician, having a non-Vietnamese or a female Vietnamese physician, and recalling exposure to Vietnamese-language media about Pap testing. Factors associated with reduced likelihood of Pap test receipt were age 65 years and older, never married, less than high school education, and income below poverty level. CONCLUSIONS: A multifaceted CBPR intervention was associated with increased Pap test receipt among Vietnamese-American women in one community.

Increasing Vietnamese-American physicians' knowledge of cervical cancer and Pap testing: impact of continuing medical education programs.

Vietnamese-American women who regularly see Vietnamese-American physicians are less likely to obtain Pap tests, perhaps because of the physicians' limited training in preventive medicine and the women's discomfort receiving Pap tests from male physicians. To address this problem, during 2001-2003, the University of California, San Francisco's (USCF) Vietnamese Community Health Promotion Project collaborated with the Vietnamese Physician Association of Northern California to organize 3 continuing medical education (CME) seminars on cervical cancer for association members. Experts gave lectures and answered questions about screening, diagnosis, and treatment to train physicians to identify risk factors, recommend Pap tests, and evaluate and conduct follow up of abnormal tests. To evaluate the seminars, we administered pre- and post-CME pencil-and-paper questionnaires. Data analysis employing the McNemar chi-squared test demonstrated significant changes in knowledge and understandingfrom pre- to post-CME in multiple areas. Results suggest that CME seminars can significantly increase Vietnamese physicians' knowledge about cervical cancer diagnosis and treatment.

Encouraging Vietnamese-American women to obtain Pap tests through lay health worker outreach and media education.

BACKGROUND: Five times more Vietnamese-American women develop cervical cancer than white women. Few studies have examined whether community-based participatory research can effectively address Asian immigrants' health problems. This article reports the preliminary evaluation of 1 such project. METHODS: A coalition of 11 organizations in Santa Clara County, California worked with university researchers to design and simultaneously implement a media education (ME) campaign and a lay health worker outreach (LHWO) program to increase Vietnamese-American women's cervical cancer awareness, knowledge, and screening. Two agencies each recruited 10 lay health workers (LHWs), who, in turn, each recruited 20 women who were then randomized into 2 groups: 10 to LHWO+ME (n = 200) and 10 to ME alone (n = 200). LHWs organized meetings with women to increase their knowledge and to motivate them to obtain Pap tests. Participants completed pre- and post-intervention questionnaires. RESULTS: At post-intervention, significantly more LHWO+ME women understood that human papillomavirus and smoking cause cervical cancer. The number of women who had obtained a Pap test increased significantly among women in both LHWO+ME and ME groups, but substantially more in the LHWO+ME group. Significantly more LHWO+ME women said they intended to have a Pap test. CONCLUSIONS: Media education campaigns can increase Vietnamese women's awareness of the importance of Pap tests, but lay health workers are more effective at encouraging women to actually obtain the tests. Lay health workers are effective because they use their cultural knowledge and social networks to create change. Researchers, community members, and community-based organizations can share expert knowledge and skills, and build one another's capacities.
