Essential Medicines Guiding principle: A limited range of carefully selected essential medicines leads to better health care, better medicines management, and lower costs Definition: Essential medicines are those that satisfy the priority health care needs of the population Selection: Selected with due regard to disease prevalence, evidence on efficacy and safety, and comparative costeffectiveness. 2| Essential Medicines List: Concept and Procedures
… 38 years of EML 1977 1 st Model list published, 208 active substances - List is revised every two years by WHO Expert Committee - 2002 Revised procedures approved by WHO (EB 109/8) - Last revision EML (April 2013) contains 374 medicines The first list was a major breakthrough in the history of medicine, pharmacy and public health Médecins sans Frontières, 2000 3| Essential Medicines List: Concept and Procedures

The Essential Medicines List and concept l "The concept of essential medicines is one of the major public health achievements in the history of WHO. l It is as relevant today as it was at it inception over 30 years ago. " Dr Margaret Chan — Director-General, WHO 5| Essential Medicines List: Concept and Procedures
Why is it 'model' l Model for its selection process (“one medicine per class” approach unless clinically relevant differences demonstrated) l Model to facilitate efforts to 'improve health' of population Regulation Quality (Rational) Responsible and evidence-based use Procurement and Supply Access: Availability, Affordability, Accessibility and Acceptability 6| Essential Medicines List: Concept and Procedures
18 th WHO Model List of Essential Medicines 2013 Report of the WHO Expert Committee, 2013 N. = 208 7| Essential Medicines List: Concept and Procedures N. = 374
EML 2013 in numbers l 374 – total number of drugs/medicines – Core list: 282 (FDC: 23) – Complementary list: 68 (FDC: 1) 8| Essential Medicines List: Concept and Procedures
EML 2013 in numbers Adult List l 374 – total number of drugs/medicines – Core list: 282 (FDC: 23) – Complementary list: 68 (FDC: 1) Pediatric List l 278 in total – Core list: 206 (FDC: 11) – Complementary list: 60 (FDC: 1) 9| Essential Medicines List: Concept and Procedures

EML criteria (EB 109/8, 2001) l Disease burden and public health need l Sound adequate data on the efficacy, safety and comparative cost-effectiveness of available treatments – Need for special diagnostic or treatment facilities considered l “Absolute cost of the treatment will not constitute a reason to exclude a medicine from the Model List that otherwise meets the stated selected criteria” 11 | Essential Medicines List: Concept and Procedures
Application period for EML 2015 (Expert Committee April 2015) l Open for 6 months: 15 June 2014 – 30 November 2014 l Applications evaluated for methodology: systematic review, evidence appraisal and synthesis (when needed, changes and new application requested) l Application can be rejected (by EML secretariat) for lack of sufficient rigour in reporting available evidence l Application sent to 2 or 3 Panel members (acting indipendently as blinded referees) 12 | Essential Medicines List: Concept and Procedures
EML: applications, referees and EC l The opinions and evaluations expressed by the 2 (or 3) referees are brought to the attention of WHO Expert Committee (EC) l EC has a plenary discussion and takes a decision l Usually without voting 13 | Essential Medicines List: Concept and Procedures

EML criteria and GRADE … the basics l A systematic review of the best available evidence l A systematic review (synthesis and appraisal) is more important than a metanalysis (pooled estimate) l Importance of summary evidence table … with appraisal of risk of bias (study defect/reliability) to evaluate confidence in estimates (for both outcomes of efficacy and safety) … this was once called quality of evidence 17 | Essential Medicines List: Concept and Procedures
