A rapid ethnographic assessment of barriers to health service utilization was conducted to identify maternal factors predicting use of child immunizations in Haiti. Methods included four focus group interviews, four natural group interviews, individual interviews with 14 health care providers and participant observation at vaccination posts. Analysis of qualitative data identified five categories of maternal factors associated with immunization use: competing priorities, low motivation, socioeconomic constraints, perceived accessibility of services, fears about health or social consequences and knowledge and folk beliefs related to vaccines. Selected variables among these factors were incorporated into a survey instrument designed to compare mothers of completely vaccinated children (cases) with mothers of incompletely vaccinated children (controls). The questionnaire was administered to 299 randomly selected mothers (217 cases, 82 controls). Bivariate and multivariate analyses found that of the factors identified through ethnographic research, only vaccine-related knowledge was significantly associated with immunization status. The utility and constraints of using ethnographic research for instrument development in epidemiological studies are discussed.

PIP: A rapid ethnographic assessment consisting of 4 focus groups, 4 natural group interviews, 14 provider interviews and participant observation rally posts was combined into a questionnaire which was tested by chi square for use in predicting which Haitian mothers utilize immunization services. The study population were mothers of 1800 children 12-23 months old in the Mirebalais Area Community Health program in the central highlands of Haiti. The program uses the rally post system, with teams visiting villages at 6-week intervals. Audio tapes and written notes were reduced to lists of all possible barriers to maternal utilization, and then regrouped into 16 categories, under 5 topics: competing priorities, lack of motivation, socioeconomic constraints, perceived accessibility of posts, fears of health consequences and knowledge of folk beliefs about vaccines. 22 questionnaire items were then developed, which were edited by the overall project director without input from the ethnographer. The questions were administered to 299 mothers, 82 with incompletely immunized, and 217 with completely immunized children. The questions which significantly predicted complete vaccination by bivariate analysis were knowledge of the name of 1 or more vaccines or illnesses, the recommended number of doses, and the correct age to begin vaccinations. It was likely that time demands from subsistence farming and income generating activities also affected service utilization, but the women probably interpreted the question on employment incorrectly.
