Promoting Rational Use of Injections within National Medicine Policies World Health Organisation Dept. Essential Drugs and Medicines Policy Safe Injection Global Network Phnom Penn October 2002

A National Medicines Policy often not implemented due to lack of political will and corruption Expresses the goals and objectives set by a government for the pharmaceutical sector and identifies the main strategies for achieving them –specifies the roles of all stakeholders (public and private) –specifies government aims, decisions & commitments –should be concerned with: equitable access, ensuring drugs are of good quality, safety and efficacy, promoting correct use of drugs

Every country needs a national drug policy because of: medical reasons –25-40% of the world population has no access to drugs –up to 50% of the worlds drugs may be used inappropriately –substandard and counterfeit drugs are not infrequent cost reasons –drugs are 20-40% of health budgets - antibiotics & injections are most expensive the need for coordinated multiple interventions –single interventions do not change behaviour long-term

Up to 56 % of primary care patients receive injections - > 90% may be medically unnecessary % of primary care patients receiving injections Chart date from: Quick et al, 1997, Managing Drug Supply ä 15 billion injections per year globally ä half are with unsterilized needle/syringe ä million infections of hepatitis B/C and up to 160,000 infections of HIV per year associated with injections

Reducing injectables in WHO’s model EDL SIGN recognised frequency of injectables in 11th EDL nature of problem (plus consequences) is identified and presented to secretariat of model EDL (EDM) –136 out of 306 active ingredients are injectables –173 injectable formulations –<50% injectables had enough information to decide syringe size –injectable ingredients listed problem presented to expert committee of model EDL expert committee agreed to: –review all injectables by the Cochrane Collaboration –insert a statement in the 12th model EDL : “ those who supply injectables should supply the necessary equipment to give them in a sterile way ”

12 national strategies to promote RUD 1. Mandated multi-disciplinary body to coordinate medicine use policies 2. Evidence-based standard treatment guidelines 3. Essential Drug Lists based on treatments of choice 4. Drug & Therapeutic Committees in hospitals 5. Problem-based training in pharmacotherapy in under-grad. training 6. Continuing medical education as a licensure requirement 7. Supervision, audit and feedback 8. Independent drug information e.g bulletins, formularies 9. Public education about drugs 10. Avoidance of perverse financial incentives 11. Appropriate and enforced drug regulation 12. Sufficient govt. expenditure to ensure availability of drugs, equip, staff

National policies to reduce unsafe inapprop. injections A national task force – a subcommittee of the NDP body - to assess unsafe inapprop. injections and plan action Select appropriate injectable drugs and equipment –public sector EDL, market withdrawal of inappropriate injections –increase availability of approp.injections (with enough equip) & alternatives –reduce availability of inappropriate injections through effective registration of drugs & dispensing outlets, enforcing Px-only regulation Train healthcare workers and the public on approp. safe use Regulate and monitor promotional activities and material Establish functional drug and therapeutic committees Eliminate economic incentives encouraging injection over-use –prescriber salaries from drug sales, especially expensive injections –dispensing fees that are a % of drug costs –flat prescription fees
