Why the use of drugs in Public Health Programmes (PHP) could carry some risk of harm Proposals regarding synergy between PHP and Pharmacovigilance (PV) WHO GUIDELINE « PHARMACOVIGILANCE AND PUBLIC HEALTH PROGRAMMES »
Slide 3-

Clinical Practice vs PHP Clinical practice PHYSICIAN Improve patient health Public Health Programmes HEALTH AUTHORITIES Improve population health (Prevent disease)
Slide 4-

Public Health or community health Science and art of preventing disease, prolonging life and promoting health and efficiency through organized community efforts.
Slide 5-

PHP Education Environmental modifications Nutrition intervention Lifestyle and behavioural changes Mass free distribution of drugs
Slide 6-

PHP characteristics Vertical and intensive programmes Prophylaxis : vaccination, preventive treatment (ivermectine, albendazole, antibiotic and antiparasitic prophylaxis…) Treatment (artemisinine derivatives against malaria, ARVs, Tuberculosis, Schistosomiasis...) Eradication (lymphatic filariasis, Trachomatis, Leprosy, poliomyelitis elimination programmes…) Involve drugs and vaccines
Slide 7-

PHP sponsors Government WHO Other non-governmental organizations: UNICEF - private associations Private sector: Onchocerciasis eradication /Merck, - Leprosis eradication/Novartis, Filariasis eradication/GSK, Trachoma eradication /Pfizer, ARV Access initiatives/ Merck, GSK, Roche, Boeringer Ingelheim, Abbot

Slide 9-

PHP monitoring Incidence and prevalence of the disease Morbidity and mortality rates Number of patients treated Number of drug units delivered What about the risk / effectiveness of drugs used?
Slide 10-

PHP guidelines (WHO, National) No mention of: ADRs Pharmacovigilance Reports
Slide 11-

1- DISEASES Tropical diseases Not well diagnosed (Exposed not always suffering from the disease) Comorbid conditions Insufficient follow-up
Slide 12-

2. POPULATION Low living standards (Malnutrition) Cultural specificities (Traditional medicines) Unlabelled and off-label indications (pregnant or breast feeding women, small children, elderly people) Food habits
Slide 13-

3. DRUGS Distribution of huge amounts of drugs Poor quality standards or counterfeits New drugs with little clinical experience Orphan drugs, donated drugs Improperly stored, delivered and used Lack of established manufacturers
Slide 14-

4. HEALTH CARE SYSTEM Under developed public health system Under developed drug regulatory system No pharmacovigilance programme Unqualified health workers Poor medical services Financial shortages
Slide 15-

Need to monitor PHPs… To detect, evaluate and prevent ADRs related to: Harm Acceptance and tolerance Misuse Dependence Effect on pregnancy and children Therapeutic failures (resistance, quality defects, counterfeits)
Slide 16-

PHP Crucial and critical Long standing Technically performed Good financial support PV Seen as a luxury discipline Not fully established No spontaneous reporting culture, no PV competence Poor support In most developing countries
Slide 17-

In those countries PHPs could provide: Opportunity to implement PV activities Offer a cohort of patients under controlled conditions to be monitored for safety over a period of time PV will Detect , evaluate, and prevent adverse events Promote rational use of drugs in mass treatment programmes Evaluate the impact of the programmes Improve acceptability of the programme

Slide 21-

RESPONSIBILITIES Promote best practice; PV While starting the programme: Is the medicine well known? Is the company represented in the country? Is the safety profile of the drug established? Is the dosage in use authorised by marketing authorisation? In case of generic product: what about bioequivalence test? NATIONAL PHP MANAGER
Slide 22-

RESPONSIBILITIES Health workers Diagnose ADRs Manage ADRs Take action Educate patients Attend meetings Promote rational use of drugs Report ADRs to the district Investigation team
Slide 23-

RESPONSIBILITIES Assess causality Investigate and manage ADRs Take action Educate patients Train health workers Promote rational use of drugs Report ADRs to the national pharmacovigilance coordinator DISTRICT INVESTIGATION TEAM

Slide 27-

Addressing the needs of public health programs Malaria HIV/AIDS Neutropenia with ACTs in malaria-HIV co-infected ? Result of repeated treatment with ACTs? Dystonia with As-Aq? SJS susceptibility Delete d4t? NVP in women? Can we use TDF without renal monitoring? Risk of severe anaemia in children with AZT? Use NVP & rifampicin concomitantly in HIV/TB patients?
Slide 28-

CONCLUSION The success of PHP is largely dependent on the participation of society and the acceptance that drugs are safe PV should be an integral part of every PHP PV is essential to promote the rational and safe use of medicines and the acceptability of mass treatment programmes.

Complementary functions for a common goal PHP Reducing morbidity and mortality Pharmacovigilance Evaluating drug effectiveness, harm and cost IMPROVE PATIENT HEALTH
