Risk No medicinal product is entirely or absolutely safe for all people, in all places, at all times. We must always live with some measure of uncertainty.
What is Pharmacovigilance? WHO definition: The science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug-related problem. This applies throughout the life-cycle of a medicine equally to the pre-approval stage as to the post-approval. ADR monitoring – Medicines safety – Drug Monitoring
What is the scope of pharmacovigilance? improve patient care and safety in relation to the use of medicines, and all medical and paramedical interventions, improve public health and safety in relation to the use of medicines, contribute to the assessment of benefit, harm, effectiveness and risk of medicines, encouraging their safe, rational and more effective (including cost-effective) use, and promote understanding, education and clinical training in pharmacovigilance and its effective communication to the public
Why pharmacovigilance? Humanitarian concerns Hippocrates admonition at least do not harm Economical concerns
Studies of ADR related deaths UK: It has been suggested that ADRs may cause 5700 deaths per year in UK Pirmohamed et al, 2004 US: ADRs were 4th-6th commonest cause of death in the US in 1994 Lazarou et al, 1998 Sweden: ADRs were 7th commonest cause of death in Sweden in 2001 Jönsson et al, 2010
125 Patients • 24 Patients experienced ADRs (19%) 59% were avoidable
Cost of ADRs in the US? Cost of drug related morbidity and mortality exceeded $177.4 billion in 2000 Ernst FR & Grizzle AJ, 2001: J American Pharm. Assoc ADR related cost to the country exceeds the cost of the medications themselves

3 tiers-approach for WHO As before Spontaneous reporting Regional trainings – WHO and UMC Country support – WHO, UMC and UMC-A More than before - Active surveillance Tools - CEMFlow for Cohort Event Monitoring Handbooks Nigeria, Tanzania, Ghana – Cohort Event Monitoring in Public Health Programmes Maintain as the cheapest, easiest, most sustainable method
Expecting the Worst - Crisis Management Support, guidelines & technical resources
3 tiers-approach for WHO As never before Indicators Minimum requirements for a Functional National PV System Fundraising EuropeAid; UNITAID, GFATM, PEPFAR; FP7 etc Centres of excellence Ghana – WHO Collaborating Centre for Advocacy and training in PV Morocco – training for francophone countries Developing networks PV Consultants Network for Africa Global Network for ADR reporting in prequalified vaccines National Centres meeting in Ghana
Activities the last few months • Ghana, May • PV conference arranged by West African Health Organization • Morocco, June • Training course for francophone countries • Togo, October • PV Consultants Network for Africa • Ghana, November • Stakeholders meeting, Donors and WHO • Activities in other parts of the world: • Training course in Singapore for Asian countries • UMC country visits in eastern European countries • Restart of PV in India • Coming – training course in Mexico
Challenges for the future To make PV systems sustainable through: • stable financing • trained and dedicated staff Create a culture of reporting • from health professionals • the public
