RESUMO
Pharmacovigilance (PV) systems in many countries in sub-Saharan Africa (SSA) are not fully functional. The spontaneous adverse events (AE) reporting rate in SSA is lower than in any other region of the world, and healthcare professionals (HCPs) in SSA countries have limited awareness of AE surveillance and reporting procedures. The GSK PV enhancement pilot initiative, in collaboration with PATH and national PV stakeholders, aimed to strengthen passive safety surveillance through a training and mentoring program of HCPs in healthcare facilities in three SSA countries: Malawi, Côte d'Ivoire, and Democratic Republic of Congo (DRC). Project implementation was country-driven, led by the Ministry of Health via the national PV center or department, and was adapted to each country's needs. The implementation phase for each country was scheduled to last 18 months. At project start, low AE reporting rates reflected that awareness of PV practices was very low among HCPs in all three countries, even if a national PV center already existed. Malawi did not have a functional PV system nor a national PV center prior to the start of the initiative. After 18 months of PV training and mentoring of HCPs, passive safety surveillance was enhanced significantly as shown by the increased number of AE reports: from 22 during 2000-2016 to 228 in 18 months to 511 in 30 months in Malawi, and ~ 80% of AE reports from trained healthcare facilities in Côte d'Ivoire. In DRC, project implementation ended after 7 months because of the SARS-CoV-2 pandemic. Main challenges encountered were delayed AE report transmission (1-2 months, due mainly to remoteness of healthcare facilities and complex procedures for transmitting reports to the national PV center), delayed or no causality assessment due to lack of expertise and/or funding, negative perceptions among HCPs toward AE reporting, and difficulties in engaging public health programs with the centralized AE reporting processes. This pilot project has enabled the countries to train more HCPs, increased reporting of AEs and identified KPIs that could be flexibly replicated in each country. Country ownership and empowerment is essential to sustain these improvements and build a stronger AE reporting culture.

Invasive meningococcal disease (IMD) imposes a significant burden on the global community due to its high case fatality rate (4-20%) and the risk of long-term sequelae for one in five survivors. An expert group meeting was held to discuss the epidemiology of IMD and immunization policies in Malaysia, Philippines, Thailand, and Vietnam. Most of these countries do not include meningococcal immunization in their routine vaccination programs, except for high-risk groups such as immunocompromised people and pilgrims. It is difficult to estimate the epidemiology of IMD in the highly diverse Asia-Pacific region, but available evidence indicate serogroup B is increasingly dominant. Disease surveillance systems differ by country. IMD is not a notifiable disease in some of them. Without an adequate surveillance system in the region, the risk and the burden of IMD might well be underestimated. With the availability of new combined meningococcal vaccines and the World Health Organization roadmap to defeat bacterial meningitis by 2030, a better understanding of the epidemiology of IMD in the Asia-Pacific region is needed.

INTRODUCTION: Pharmacovigilance (PV) systems to monitor drug and vaccine safety are often inadequate in sub-Saharan Africa. In Malawi, a PV enhancement initiative was introduced to address major barriers to PV. OBJECTIVE: The objective of this initiative was to improve reporting of adverse events (AEs) by strengthening passive safety surveillance via PV training and mentoring of local PV stakeholders and healthcare providers (HCPs) at their own healthcare facilities (HCFs). METHODS: An 18-month PV training and mentoring programme was implemented in collaboration with national stakeholders, and in partnership with the Ministry of Health, GSK and PATH. Two-day training was provided to Expanded Programme on Immunisation coordinators, identified as responsible for AE reporting, and four National Regulatory Authority representatives. Abridged PV training and mentoring were provided regularly to HCPs. Support was given in upgrading the national PV system. Key performance indicators included the number of AEs reported, transmission of AE forms, completeness of reports, serious AEs reported and timeliness of recording into VigiFlow. RESULTS: In 18 months, 443 HCPs at 61 HCFs were trained. The number of reported AEs increased from 22 (January 2000 to October 2016) to 228 (November 2016 to May 2018), enabling Malawi to become a member of the World Health Organization Programme for International Drug Monitoring. Most (98%) AE report forms contained mandatory information on reporter, event, patient and product, but under 1% were transmitted to the national PV office within 48 h. CONCLUSION: Regular PV training and mentoring of HCPs were effective in enhancing passive safety surveillance in Malawi, but the transmission of reports to the national PV centre requires further improvement.
When a medicine or vaccine is made available for use, healthcare organisations maintain regular surveillance to confirm that the medicinal product is safe and effective. The efficiency of this surveillance depends mainly on the healthcare system and medical practices in place in each country. An important element is an effective procedure for identifying and reporting any unwanted medical occurrences (adverse events) after taking a medicinal product. In countries where regular safety surveillance has not been maintained, it is important to train and mentor healthcare providers on the need to be aware of adverse events and the importance of adhering to safety reporting procedures. GSK and partners conducted a pilot project in Malawi with the aim of improving adverse event reporting by training and mentoring healthcare providers. Training sessions and continuous mentoring were conducted over 18 months, involving 443 healthcare providers at 61 healthcare facilities. There was a large increase in the number of adverse events reported: from 22 in the 16-year period before the project started to 228 during the 18-month project period. This project showed that the training and mentoring programme for healthcare providers was effective in increasing the number of adverse events reported. This enabled Malawi to join the World Health Organization's international safety reporting scheme. Other countries facing similar challenges in safety surveillance systems could benefit from a similar approach.
