SIAPS has supported the Division: Pharmaceutical Services to conduct support supervisory visit (SSVs) to monitor and assess progress of the supported programs and provide recommendations to further strengthen implementation of pharmaceutical service delivery. The SSVs are used to monitor the extent of implementation of interventions aimed at strengthening pharmaceutical services in MRMDs, hospitals, and primary health care (PHC) facilities; identify challenges in the services; provide onsite support; and make recommendations to address the challenges. These visits are carried out once a year, and the SSV teams check whether issues identified from previous visits have been addressed. SIAPS has supported the MOHSS to implement strategies to strengthen the inventory management of antiretroviral (ARV) medicines and the ART pharmaceutical system. A stronger inventory management system will enable the country to cope with the scale-up of ART services, which increased quantities of health commodities and more complex inventory management tasks.
Using Support Supervisory Visits for Monitoring and Mentorship for Pharmaceutical Services Delivery in Namibia
SIAPS helped improve pharmaceutical product quality by building the capacity of the Namibia Medicines Regulatory Council (NMRC) to review medicine registration dossiers; inspect pharmaceutical manufacturing facilities and finished (imported) products at ports of entry and in the marketplace; to chemically test medicines compliance with established standards; and monitor overall compliance with applicable regulatory standards and norms. In addition, SIAPS supported MOHSS in strengthening the management and regulation of medical devices and support equipment in Namibia, and in revising the National Medicines Policy, a crucial of pharmaceutical regulation and governance. SIAPS supported the reconfiguration of the desk-top Pharmadex tool to a web-based application. In general, the six-year support of the SIAPS project to the NMRC contributed to the strengthening of this regulatory agency, which in turn, contributed to improvements in service delivery to the clients. The registration process improved, to decrease the long-standing backlog of dossiers; PMS ensured safety and quality of pharmaceuticals; and implementation of web-based Pharmadex provided a means for clients/applicants to upload applications and follow up the progress of dossier review, which reduced workload for NMRC staff. SIAPS provided continuous TA for the restructuring of the NMRC.
Therapeutics Information and Pharmacovigilance Centre’s Analysis of Spontaneous Adverse Events due to Antiretroviral and Other Medicines
The use of antiretrovirals (ARVs) in combination for treating patients with HIV has greatly ameliorated morbidity and mortality by reducing viral load to undetectable levels and boosting the body’s immunity. However serious adverse reactions causing long- or short-term effects have been associated with ARV treatment. These reactions have caused major concerns internationally, potentially threatening patient adherence to long-term treatment. The duration of treatment of patients infected with HIV; co-morbid conditions, such as tuberculosis (TB) and malaria; and the complications due to HIV infection or AIDS make it difficult to determine the exact cause of the adverse events (AEs) experienced by patients taking ARV medicines. The prevalence of co-morbid conditions differs across socioeconomic groups and geographical regions, which may contribute to differences in ARV toxicity profiles. Hence, it is recommended that national HIV treatment programs establish population-level ARV toxicity profiles for their countries. Therefore, with increased survival of patients and the long-term duration of antiretroviral treatment (ART), it is important for national pharmacovigilance centers to monitor the immediate and long-term effects of these ARVs on the population. A simple, practical, and cost-effective method for evaluating the safety of drugs approved for human use is the spontaneous reporting of AEs to a pharmacovigilance center. This method is helpful for identifying serious and rare medicine-associated AEs. The evaluation of these AEs informs regulatory decisions on improving the safety of medicines in the country and globally. The objective of the Analysis of Namibia Therapeutics Information and Pharmacovigilance Centre’s Data was to identify drug safety concerns associated with the use of antiretroviral medicines in Namibia’s HIV treatment program, by analyzing pharmacovigilance data generated from spontaneous reports of suspected adverse events (AEs).
The SIAPS-developed AMR coalition-based strategy identifies educational institutions, such as UNAM; therapeutic committees (TCs); and key institutions involved in AMR, such as the National Institute of Pathology (NIP) as key players in the pre- and in-service training of health care professionals to enhance RMU and combat AMR. SIAPS collaborated with key institutions, including the MoHSS, Div:PhSs, UNAM-SOM, UNAM-SOP, NIP, and TCs in the Kunene and Karas regions, in activities to reduce hospital-acquired infections (HAIs); improve infection prevention and control (IPC); and promote RMU in Namibia.
SIAPS supported the MoHSS to design and implement a web-based electronic information system (dashboard) for both patient and stock status in Namibia. It was designed to improve coordination among facility, district, regional, and national stakeholders involved in HIV commodity management; increase the use of pharmaceutical information for management decision making at all levels of health care; and improve planning for financial resources for pharmaceutical commodities. The dashboard comprises a module for monitoring 22 pharmaceutical services delivery indicators, a module that summarizes the number of people accessing ART services, and an early warning system against stock-outs of antiretrovirals (ARVs) and other essential medicines.
Consolidating SIAPS’ Five-Year Support to the Ministry of Health and Social Services for Strengthening Pharmacovigilance in Namibia
The goal of SIAPS in Namibia was to improve the quality and safety of pharmaceutical services to achieve sustained HIV epidemic control. Since 2012, SIAPS focused on interventions that increased the availability of quality antiretrovirals (ARVs), other essential medicines, and services to sustain more than 80% ART coverage of patients in need. SIAPS activities also contributed to ensuring patient safety through pharmacovigilance (PV) activities.
