Conclusion: Interventions to Change Drug Use • Best evidence in PHC area • Focused, problem oriented repeated training • Supervision or self monitoring with simple indicators • Peer group oriented guideline development • Evidence lacking for : • Private sector, adults, and chronic diseases Framework for Changing Drug Use Practices

29. Conclusion: Interventions to Change Drug Use (2) • Few interventions in hospitals in developing countries but based on experience in developed countries great potential exists for hospital interventions to be successful • Consumers need to be involved. Experience is lacking but interactive, context specific programs using a mix of communication channels are likely to be effective Framework for Changing Drug Use Practices
