RESUMEN

PURPOSE: To describe the first year results of Rwanda's Screen, Notify, See, and Treat cervical cancer screening program, including challenges encountered and revisions made to improve service delivery. METHODS: Through public radio broadcasts, meetings of local leaders, church networks, and local women's groups, public awareness of cervical cancer screening opportunities was increased and community health workers were enlisted to recruit and inform eligible women of the locations and dates on which services would be available. Screening was performed using human papillomavirus (HPV) DNA testing technology, followed by visual inspection with acetic acid (VIA), and cryotherapy, biopsy, and surgical treatment for those who tested HPV-positive. These services were provided by five district hospitals and 15 health centers to HIV-negative women of age 35-45 and HIV-positive women of age 30-50. Service utilization data were collected from the program's initiation in September 2013 to October 2014. RESULTS: Of 7,520 cervical samples tested, 874 (11.6%) screened HPV-positive, leading 780 (89%) patients to undergo VIA. Cervical lesions were found in 204 patients (26.2%) during VIA; of these, 151 were treated with cryoablation and 15 were referred for biopsies. Eight patients underwent complete hysterectomy to treat advanced cervical cancer. Challenges to service delivery included recruitment of eligible patients, patient loss to follow-up, maintaining HIV status confidentiality, and efficient use of consumable resources. CONCLUSION: Providing cervical cancer screening services through public health facilities is a feasible and valuable component of comprehensive women's health care in resource-limited settings. Special caution is warranted in ensuring proper adherence to follow-up and maintaining patient confidentiality.

RESUMEN

BACKGROUND: Cervical cancer is the most common female cancer in Rwanda that, in 2011, became the first African country to implement a national vaccination programme against human papillomavirus (HPV). METHODS: To provide a robust baseline for future evaluations of vaccine effectiveness, cervical cell specimens were obtained from 2508 women aged 18-69 years from the general population in Kigali, Rwanda, during 2013/14. 20 % of women were HIV-positive. Samples were used for liquid-based cytology and HPV testing (44 types) with GP5+/6+ PCR. RESULTS: HPV prevalence was 34 %, being highest (54 %) in women ≤19 years and decreasing to 20 % at age ≥50. Prevalence of high risk (HR) HPV and cytological abnormalities was 22 and 11 % respectively (including 2 % with high-grade squamous intraepithelial lesions, HSIL) decreasing with age. Age-standardised prevalence of HR HPV was 22 % (or 19 % among HIV-negative women), and HPV16 was the most common type. Prevalence of HPV and cytological abnormalities were significantly higher in HIV-positive than HIV-negative women, and the difference increased with age. Other significant risk factors for HPV positivity in multivariate analyses were high lifetime number of sexual partners, receiving cash for sex, and being a farmer. 40 % of women with HSIL were infected with HPV16/18 and there was no significant difference between HIV-positive and HIV-negative women. CONCLUSIONS: This study confirms Rwanda to be a setting of high prevalence of HPV and cervical disease that is worsened by HIV. These data will serve as a robust baseline for future evaluations of HPV vaccine programme effectiveness.

RESUMEN

Bhutan (2010) and Rwanda (2011) were the first countries in Asia and Africa to introduce national, primarily school-based, human papillomavirus (HPV) vaccination programmes. These target 12 year-old girls and initially included catch-up campaigns (13-18 year-olds in Bhutan and ninth school grade in Rwanda). In 2013, to obtain the earliest indicators of vaccine effectiveness, we performed two school-based HPV urine surveys; 973 female students (median age: 19 years, 5th-95th percentile: 18-22) were recruited in Bhutan and 912 (19 years, 17-20) in Rwanda. Participants self-collected a first-void urine sample using a validated protocol. HPV prevalence was obtained using two PCR assays that differ in sensitivity and type spectrum, namely GP5+/GP6+ and E7-MPG. 92% students in Bhutan and 43% in Rwanda reported to have been vaccinated (median vaccination age = 16, 5th-95th: 14-18). HPV positivity in urine was significantly associated with sexual activity measures. In Rwanda, HPV6/11/16/18 prevalence was lower in vaccinated than in unvaccinated students (prevalence ratio, PR = 0.12, 95% confidence interval, CI: 0.03-0.51 by GP5+/GP6+, and 0.45, CI: 0.23-0.90 by E7-MPG). For E7-MPG, cross-protection against 10 high-risk types phylogenetically related to HPV16 or 18 was of borderline significance (PR = 0.68; 95% CI: 0.45-1.01). In Bhutan, HPV6/11/16/18 prevalence by GP5+/GP6+ was lower in vaccinated than in unvaccinated students but CIs were broad. In conclusion, our study supports the feasibility of urine surveys to monitor HPV vaccination and quantifies the effectiveness of the quadrivalent vaccine in women vaccinated after pre-adolescence. Future similar surveys should detect increases in vaccine effectiveness if vaccination of 12 year-olds continues.

RESUMEN

As the pace of vaccine uptake accelerates globally, there is a need to document low-income country experiences with vaccine introductions. Over the course of five years, the government of Rwanda rolled out vaccines against pneumococcus, human papillomavirus, rotavirus, and measles & rubella, achieving over 90% coverage for each. To carry out these rollouts, Rwanda's Ministry of Health engaged in careful review of disease burden information and extensive, cross-sectoral planning at least one year before introducing each vaccine. Rwanda's local leaders, development partners, civil society organizations and widespread community health worker network were mobilized to support communication efforts. Community health workers were also used to confirm target population size. Support from Gavi, UNICEF and WHO was used in combination with government funds to promote country ownership and collaboration. Vaccination was also combined with additional community-based health interventions. Other countries considering rapid consecutive or simultaneous rollouts of new vaccines may consider lessons from Rwanda's experience while tailoring the strategies used to local context.

RESUMEN

BACKGROUND: Detailed cost evaluations of delivery of new vaccines such as pneumococcal conjugate, human papillomavirus (HPV), and rotavirus vaccines in low and middle-income countries are scarce. This paper differs from others by comparing the costs of introducing multiple vaccines in a single country and then assessing the financial and economic impact at the time and implications for the future. The objective of the analysis was to understand the introduction and delivery cost per dose or per child of the three new vaccines in Rwanda to inform domestic and external financial resource mobilization. METHODS: Start-up, recurrent, and capital costs from a government perspective were collected in 2012. Since pneumococcal conjugate and HPV vaccines had already been introduced, cost data for those vaccines were collected retrospectively while prospective (projected) costing was done for rotavirus vaccine. RESULTS: The financial unit cost per fully immunized child (or girl for HPV vaccine) of delivering 3 doses of each vaccine (without costs related to vaccine procurement) was $0.37 for rotavirus (RotaTeq(®)) vaccine, $0.54 for pneumococcal (Prevnar(®)) vaccine in pre-filled syringes, and $10.23 for HPV (Gardasil (®)) vaccine. The financial delivery costs of Prevnar(®) and RotaTeq(®) were similar since both were delivered using existing health system infrastructure to deliver infant vaccines at health centers. The total financial cost of delivering Gardasil(®) was higher than those of the two infant vaccines due to greater resource requirements associated with creating a new vaccine delivery system in for a new target population of 12-year-old girls who have not previously been served by the existing routine infant immunization program. CONCLUSION: The analysis indicates that service delivery strategies have an important influence on costs of introducing new vaccines and costs per girl reached with HPV vaccine are higher than the other two vaccines because of its delivery strategy. Documented information on financial commitments for new vaccines, particularly from government sources, is a useful input into country policy dialogue on sustainable financing and co-financing of new vaccines, as well as for policy decisions by donors such as Gavi, the Vaccine Alliance.

RESUMEN

Despite an estimated 456,000 deaths caused by cancer in sub-Saharan Africa in 2012 and a cancer burden that is predicted to double by 2030, the region accounts for only 0·3% of worldwide medical expenditure for cancer. Challenges to cancer care in sub-Saharan Africa include a shortage of clinicians and training programmes, weak healthcare infrastructure, and inadequate supplies. Since 2011, Rwanda has developed a national cancer programme by designing comprehensive, integrated frameworks of care, building local human resource capacity through partnerships, and delivering equitable, rights-based care. In the 2 years since the inauguration of Rwanda's first cancer centre, more than 2500 patients have been enrolled, including patients from every district in Rwanda. Based on Rwanda's national cancer programme development, we suggest principles that could guide other nations in the development of similar cancer programmes.

RESUMEN

BACKGROUND: In some settings, rotavirus vaccines have been associated with a small risk of intussusception. This study describes the demographics, clinical characteristics and outcomes of children with intussusception in Rwanda before vaccine introduction in May 2012. METHODS: We retrospectively reviewed data on pediatric patients treated for intussusception at University Teaching Hospital of Kigali from January 2009 to June 2012. Hospital registries were reviewed to identify intussusception cases. Archived patient files were abstracted to collect data on demographics, clinical presentation, surgery and outcome. RESULTS: During the study period, 70 children ≤19 years of age were treated for intussusception and patient files were retrieved for 60 (86%) cases. Over half of patients (58%) were <1 year of age and 90% were transferred from a district hospital. Only 30% of patients presented within 3 days of symptom onset and 35% experienced a delay of ≥6 hours between surgical review and surgery. Surgical complications were experienced by 35% of children. Over 1 quarter (28%) of children died. Compared with children who survived, children who died were significantly more likely to have experienced complications (21% vs. 71%; P < 0.001) and to be female (28% vs. 65%; P = 0.009). DISCUSSION: Mortality due to intussusception was high among Rwanda children. Delays in presentation and treatment were common. Assessing trends in the number of cases to monitor for vaccine-associated intussusception will be difficult. Additional work is needed to further understand risk factors for mortality, to calculate incidence rates and to monitor the safety of the rotavirus vaccination program.

RESUMEN

PROBLEM: Although it is highly preventable and treatable, cervical cancer is the most common and most deadly cancer among women in Rwanda. APPROACH: By mobilizing a diverse coalition of partnerships, Rwanda became the first country in Africa to develop and implement a national strategic plan for cervical cancer prevention, screening and treatment. LOCAL SETTING: Rwanda - a small, landlocked nation in East Africa with a population of 10.4 million - is well positioned to tackle a number of "high-burden" noncommunicable diseases. The country's integrated response to infectious diseases has resulted in steep declines in premature mortality over the past decade. RELEVANT CHANGES: In 2011-2012, Rwanda vaccinated 227,246 girls with all three doses of the human papillomavirus (HPV) vaccine. Among eligible girls, three-dose coverage rates of 93.2% and 96.6% were achieved in 2011 and 2012, respectively. The country has also initiated nationwide screening and treatment programmes that are based on visual inspection of the cervix with acetic acid, testing for HPV DNA, cryotherapy, the loop electrosurgical excision procedure and various advanced treatment options. LESSONS LEARNT: Low-income countries should begin to address cervical cancer by integrating prevention, screening and treatment into routine women's health services. This requires political will, cross-sectoral collaboration and planning, innovative partnerships and robust monitoring and evaluation. With external support and adequate planning, high nationwide coverage rates for HPV vaccination and screening for cervical cancer can be achieved within a few years.

RESUMEN

PROBLEM: Virtually all women who have cervical cancer are infected with the human papillomavirus (HPV). Of the 275,000 women who die from cervical cancer every year, 88% live in developing countries. Two vaccines against the HPV have been approved. However, vaccine implementation in low-income countries tends to lag behind implementation in high-income countries by 15 to 20 years. APPROACH: In 2011, Rwanda's Ministry of Health partnered with Merck to offer the Gardasil HPV vaccine to all girls of appropriate age. The Ministry formed a "public-private community partnership" to ensure effective and equitable delivery. LOCAL SETTING: Thanks to a strong national focus on health systems strengthening, more than 90% of all Rwandan infants aged 12-23 months receive all basic immunizations recommended by the World Health Organization. RELEVANT CHANGES: In 2011, Rwanda's HPV vaccination programme achieved 93.23% coverage after the first three-dose course of vaccination among girls in grade six. This was made possible through school-based vaccination and community involvement in identifying girls absent from or not enrolled in school. A nationwide sensitization campaign preceded delivery of the first dose. LESSONS LEARNT: Through a series of innovative partnerships, Rwanda reduced the historical two-decade gap in vaccine introduction between high- and low-income countries to just five years. High coverage rates were achieved due to a delivery strategy that built on Rwanda's strong vaccination system and human resources framework. Following the GAVI Alliance's decision to begin financing HPV vaccination, Rwanda's example should motivate other countries to explore universal HPV vaccine coverage, although implementation must be tailored to the local context.
