Use of formative research in developing a knowledge translation approach to rotavirus vaccine introduction in developing countries.

BackgroundRotavirus gastroenteritis is the leading cause of diarrheal disease mortality among children under five, resulting in 450,000 to 700,000 deaths each year, and another 2 million hospitalizations, mostly in the developing world. Nearly every child in the world is infected with rotavirus at least once before they are five years old.Vaccines to prevent rotavirus or minimize its severity are now becoming available, and have already been introduced into the public vaccine programs of several Latin American countries. The World Health Organization (WHO) has made rotavirus vaccine introduction in developing countries a high priority.The WHOs Guidelines for Vaccine Introduction indicates that a key determinant to achieving vaccine introduction is the public health priority of the disease, suggesting that where the disease is not a priority uptake of the vaccine is unlikely. WHO recommends conducting a qualitative analysis of opinions held by the public health community to determine the perceptions of the disease and the priority given to the vaccine.MethodsThis paper presents the formative research results of a qualitative survey of public health providers in five low- and middle-income countries to determine if and to what degree rotavirus is perceived to be a problem and the priority of a vaccine. Open-ended surveys were carried out through focus group discussions and one-on-one interviews.ResultsResearchers discovered that in all five countries knowledge of rotavirus was extremely low, and as a result was not considered a high priority. However, diarrhea among young children was considered a high priority among public health providers in the three poorest countries with relatively high levels of child mortality: India, Indonesia, and Nicaragua.ConclusionIn the poorest countries, advocacy and communication efforts to raise awareness about rotavirus sufficient for prioritization and accelerated vaccine introduction might benefit from a knowledge translation approach that delivers information and evidence about rotavirus through the broader context of diarrheal disease control, an existing priority, and including information about other new interventions, specifically low-osmolarity oral rehydration solution and zinc treatment.

Determinants of Human Papillomavirus Vaccine Acceptability in Latin America and the Caribbean

Prophylactic human papillomavirus (HPV) vaccines provide promise as a key component of future cervical cancer prevention programs in the Latin America and the Caribbean region. The successful introduction and acceptance of these vaccines will depend on a range of factors including awareness of cervical cancer as a problem, affordability of the vaccine, political will, competition with other vaccines, feasibility of vaccine delivery and acceptability of the vaccine among the range of groups who will influence uptake. While existing data about acceptability from Latin America and the Caribbean is scarce, it is clear that health policymakers, providers and the general public lack knowledge about HPV and cervical cancer. Furthermore, they would value more local epidemiologic data related to cervical cancer. Price is currently a major barrier to vaccine acceptability and a priority for advocacy. More research is required in Latin America and the Caribbean to determine what messages and strategies will work in these communities.

Acceptability of self-collection sampling for HPV-DNA testing in low-resource settings: a mixed methods approach

BackgroundVaginal self-sampling with HPV-DNA tests is a promising primary screening method for cervical cancer. However, women’s experiences, concerns and the acceptability of such tests in low-resource settings remain unknown.MethodsIn India, Nicaragua, and Uganda, a mixed-method design was used to collect data from surveys (N = 3,863), qualitative interviews (N = 72; 20 providers and 52 women) and focus groups (N = 30 women) on women’s and providers’ experiences with self-sampling, women’s opinions of sampling at home, and their future needs.ResultsAmong surveyed women, 90% provided a self- collected sample. Of these, 75% reported it was easy, although 52% were initially concerned about hurting themselves and 24% were worried about not getting a good sample. Most surveyed women preferred self-sampling (78%). However it was not clear if they responded to the privacy of self-sampling or the convenience of avoiding a pelvic examination, or both. In follow-up interviews, most women reported that they didn’t mind self-sampling, but many preferred to have a provider collect the vaginal sample. Most women also preferred clinic-based screening (as opposed to home-based self-sampling), because the sample could be collected by a provider, women could receive treatment if needed, and the clinic was sanitary and provided privacy. Self-sampling acceptability was higher when providers prepared women through education, allowed women to examine the collection brush, and were present during the self-collection process. Among survey respondents, aids that would facilitate self-sampling in the future were: staff help (53%), additional images in the illustrated instructions (31%), and a chance to practice beforehand with a doll/model (26%).ConclusionSelf-and vaginal-sampling are widely acceptable among women in low-resource settings. Providers have a unique opportunity to educate and prepare women for self-sampling and be flexible in accommodating women’s preference for self-sampling.

Cervical cancer prevention and the Millennium Development Goals

The advent of new technologies such as the human papillomavirus (HPV) vaccine and HPV DNA tests--along with new insights into the appropriate use of low-resource technologies such as visual inspection of the cervix and treatment of cervical lesions with cryotherapy--have increased optimism about the potential for effective disease control in low-resource settings. Nevertheless, it is also important to ask ourselves how new health initiatives contribute, or fail to contribute, to major global undertakings such as achievement of the Millennium Development Goals (MDGs). While reproductive health in general, and cervical cancer prevention in particular, are not explicitly mentioned among the MDGs, they are implied; and it is certain that women cannot contribute to sustainable development without good health. The question is, in what ways do scaled-up cervical cancer prevention activities, including introduction of the new HPV vaccines and increased access to precancer screening and treatment, contribute to attainment of the MDGs?

Advocacy, communication, and partnerships: Mobilizing for effective, widespread cervical cancer prevention

Both human papillomavirus (HPV) vaccination and screening/treatment are relatively simple and inexpensive to implement at all resource levels, and cervical cancer screening has been acknowledged as a “best buy” by the WHO. However, coverage with these interventions is low where they are needed most. Failure to launch or expand cervical cancer prevention programs is by and large due to the absence of dedicated funding, along with a lack of recognition of the urgent need to update policies that can hinder access to services. Clear and sustained communication, robust advocacy, and strategic partnerships are needed to inspire national governments and international bodies to action, including identifying and allocating sustainable program resources. There is significant momentum for expanding coverage of HPV vaccination and screening/preventive treatment in low‐resource settings as evidenced by new global partnerships espousing this goal, and the participation of groups that previously had not focused on this critical health issue.

Implementing the world health organization code: Improved information for mothers

Beginning in 1977 in the United States and in 1979 internationally, Nestle S.A., a multinational corporation, became the target of a major boycott. Criticism of the companys activities focused on its attempts to influence health professionals in Third World countries to recommend the companys infant formula to mothers, and on the allegedly biased nature of the companys educational materials and product information on infant feeding. In 1981, the company accepted the International Code of Marketing of Breast-milk Substitutes, which was passed by the World Health Assembly that same year ,(1). However, the international committee that organized the boycott contended that the company was not complying with four specific areas of the code, and insisted that the boycott would not be lifted until the company complied fully with the recommendations made by the World Health Organization (WHO). Among other stipulations, the committee called for the company to change its product labels and educational materials regarding the benefits, use, and preparation of infant formula. In the Joint Statement of Understanding signed in January 1984 by the company and the boycott committee, the company agreed to seek advice from health communication c.onsultants to revise its labels and educational materials, and to consult with representatives of the boycott committee, WHO, and the United Nations Childrens Fund (UNICEF) on its progress in the four areas of contention. To fulfill its pledge to seek advice from health communication consultants, the company contracted with our organization, a U.S.-based, international private nonprofit organization (Note 1), to assist it in revising its infant-formula labels and educational materials on breastfeeding. This case study outlines a successful approach to implementing parts of the international code (Note 2). It also is an example of cooperation between private industry and the international development community to foster socially responsible marketing of infant formula. Other companies may find that this approach can help make their information conform to the code.
