Access to Controlled Medicines Willem Scholten, PharmD, MPA Team Leader, Access to Controlled Medicines, World Health Organization, Geneva, Switzerland TECHNICAL BRIEFING SEMINAR Geneva, 29 October – 2 November 2012
Overview • The global pain management crisis • Causes of the problem • Working methods for improvement • Including WHO Policy guidelines
Uses of Controlled Medicines • Opioid analgesics: e. g. morphine moderate and severe pain • Long-acting opioid agonists: methadone, buprenorphine treatment of opioid dependence • Ergometrine and ephedrine: emergency obstetrics • Benzodiazepines: anxiolytics, hypnotics, antiepileptics • Phenobarbital: antiepileptic
Inequality • 93.8% of all (licit) morphine consumption by 21.8% of the world population (INCB 2010, Data for 2009) • 4.7 billion people live in countries where medical opioid consumption is near to zero (on a total world population of 6.5 billion) (Seya et al. 2011, Data for 2006)
Other Controlled Medicines Opioid analgesics best documented. Also access problems with other controlled medicines • Opioid agonist treatment of opioid dependence: • World-wide coverage: 8% of patients only • Phenobarbital • 80% of epilepsy patients in Africa have no access • Ketamine !!!!!!!!!!! • Upcoming surgery/anaesthesia crisis world-wide
Consumption increase • Global consumption of strong opioids rose from • 1.82 mg/capita of Morphine Equivalents (1980) to • 59.66 mg / capita (2009) (Pain & Policy Studies Group, University of Wisconsin) • Increase is faster since the introduction of the Three-Step Ladder of Cancer Pain Relief (WHO, 1986) • Most of increase in industrialized countries
Adequacy Consumption of Opioid Analgesics (2007) from: Seya MJ et al, J Pain & Pall Care Pharmacother 2011;25:6-18
Adequacy of Consumption Measure (ACM) ≥1 Adequate 0.3 – 1 Moderate 0.1 – 0.3 Low 0.03 – 0.1 Very Low < 0.03 "No" consumption • Logarithmic scale!!!
Adequacy as a function of development Data for 2006
Method for ACM • Based on • Consumption of all strong opioids (INCB statistics 2006) • Morbidity (HIV, cancer, lethal injuries) • Benchmark: average of Top-20 Human Develop Index • Method for calculating long term needs Long term targets for countries • Unsuitable for accurate calculation of short term needs A first comparison between the consumption of and the need for opioid analgesics at country, regional and global levels Seya MJ et al, J Pain and Pall Care Pharmacother, 2011;25:6-18
ACM Benchmark • No generally accepted Good per Capita Consumption Level • Assumption: most developed countries are near to "good" Average of " Top–x " from Human Development Index (HDI) can be used as benchmark • Choice of x is arbitrary – but major impact on outcome!
Adequacy of opioid consumption(x million people)* * Number of people living in countries where opioid consumption is …
Global need to treat all pain • Current global consumption of strong opioids: 213 000 kg morphine equivalents (2006) • Needed to treat all pain adequately: 1 292 000 kg morphine equivalents Seya MJ et al., J of Pain and Palliative Care Pharmacotherapy; 2011;25:6-18
Validation? For the Netherlands: ACM: 51 % (Seya et al.) • 43% of chronic non-cancer pain patients report not to receive pain treatment • 79% of patients believe their pain is inadequately treated Bekkering GE et al, Epidemiology of chronic pain and its treatment in the Netherlands. The Netherlands J of Med. 2011; 69(3): 141 – 152 (Systematic review) Studies for other European countries on their way; this will allow validation of ACM-method

Because they have… • Excessive fear for dependence • Excessive fear for diversion • Neglected and ignored medical needs
Why do these barriers exist and what are they? • One century of drug control • 23 January 1912, The Hague: first Opium Convention • Focus has been on prevention of • abuse, • dependence and • crime related to trafficking • Medical and scientific supply "forgotten"
Preamble Single Convention Single Convention on Narcotic Drugs (1961; as amended) Recognizing that the medical use of narcotic drugs continues to be indispensable for the relief of pain and suffering and that adequate provision must be made to ensure the availability of narcotic drugs for such purposes …
Categories of barriers • Legislation and Policy • Knowledge • Attitudes • Health-Care Professionals • General Public • Economic
Legislative barriers • Inappropriate laws and regulations • Rules often not preventing abuse, dependence and diversion • Rules often a barrier for medical access • Limitations on prescriptions and administration • Duration • Maximum dosage • Administration of medicines restricted • Special prescription forms • Limitation of outlets • Limitations on who is allowed to prescribe • Special licensing in spite of medical degree
Policy barriers • Access to controlled medicines not included in national policy plans • National Pharmaceutical Policy Plan • National Cancer Control Plan • National HIV/AIDS Plan • Investigation/prosecution of prescribers • Investigation of those who subscribe at an adequate level • Too much red tape • Speed of licensing procedures
Knowledge barriers • Medical Schools • Many do not teach opioid analgesia • Physicians • Fear for dependence • Unfamiliarity with prescribing and dosing • Prescribing obsolete medicines (pethidine=meperidine still in use) • Unfamiliarity with pain assessment • Learned "not to treat symptoms, but disease"
Attitude barriers • Patient and family • Association morphine impending death • Conviction that suffering chastens • Health-care and other professionals • Continuing use of obsolete or counter-productive terminology • Seniors not allowing juniors to introduce new techniques
Economical and procurementbarriers • General issues as for other medicines e.g. • Insurance and affordability • Distribution problems • In some countries Separate distribution systems for controlled medicines
Improving access Suggested steps • Policy analysis • Legal analysis (external lawyer, trained on the issue) • National policy on improving access • National one-day symposia for awareness raising
Working methods (1) • Preferrably: working group that includes • authorities • representatives of relevant health-care professionals • Pharmacists, GPs, PC, oncology, surgery…. (pain everywhere!) • Treatment of opioid dependence • Veterinarians? • patient representatives
Working methods (2) • Full analysis of barriers • Policy planning • Priority setting • Implementation • Evaluate, set new priorities and adjust policy plan etc…
