The Single Convention establishes two mechanisms: (1) The estimates system for narcotic drug requirements , and (2) The statistical returns system for narcotic drugs
Drug Requirements Definition
The Single Convention (Article 19) defines drug requirements as the quantities of drugs that will be used in the country for medical and scientific consumption, as well as for the manufacturing of other licit preparations.
How are estimated requirements established for a country?
• Governments estimate amount of controlled substances needed to satisfy all medical and scientific requirements for the next year • Submit Estimates to INCB on Form B by June 30 th of each year for the following year (i.e., by 30 June 2012 for 2013 estimated requirements) • INCB evaluates, confirms and publishes the estimate for each Government • Government may then manufacture or import controlled substances within that amount to distribute to medical facilities for the treatment of patients

Supplementary Estimates
• Single Convention authorizes Governments to submit a supplementary estimate • Government should include explanation of why an increase is needed • Can be submitted at any time, and can be approved quickly by INCB when requested
Reasons for not submitting estimated requirements
Governments lack appropriate methods and procedures for estimating opioid requirements Governments do not allocate sufficient personnel or resources to administer the technical function of estimating drug requirements
Why are Estimates of opioids important for the INCB?
“Governments and the [International Narcotics Control] Board need to have accurate information about medical needs for narcotic drugs. In the case of narcotic drugs that are opiates, it is particularly important to accurately estimate all medical needs because the Board must make arrangements well in advance to cultivate a sufficient quantity of poppy plants.” (p. 1) (INCB, 1996)
Related Issues Impacting Estimates
Cost of purchasing, importing medicines Difficulty finding an interested supplier, due to small profit margin for certain low-cost opioids such as IR oral morphine Difficulty identifying Exporter/Supplier with affordable prices, appropriate formulations Challenges in identifying specific formulations and amounts of medicines needed

Estimated Requirements vs. Need for Controlled Medicines
Estimated Requirements: quantities necessary to provide medical treatment through existing health-care infrastructure Needs: quantities necessary to provide medical treatment for all health problems in country
Methods for Estimating Opioid Requirements
1) Consumption –based method 2) Service –based method 3) Morbidity –based method International Narcotics Control Board and World Health Organization. Guide on Estimating Requirements for Substances under International Control. Vienna, Austria: United Nations; 2012. http://www.incb.org/incb/en/guide on-estimating-requirements.html
1) Consumption –based method
Based on use of opioids over recent years Developed using an average of the amounts consumed in recent years
Example: Calculating morphine requirement of country X for 2013
Year 2010 2011 2012 Morphine use (kg) 17 15 18
Average = 16.7 kg + (10%) 1.67 kg 18.4 kg Estimated Morphine Requirement for 2013
1) Consumption –based method
Appropriate to use when:
reliable data about recent opioid consumption can be collected, demand for health-care services has reached a relatively steady level, well-functioning supply management system, and use of controlled substances is rational
Limitations:
Does not provide a basis for improving rational use and accuracy, stock-outs, losses, and waste may reduce accuracy, and incomplete data due to poor stock management, inadequate record-keeping or reporting to authorities
2) Service –based method
Calculates requirements for controlled substances based on current levels of use of each substance (for all indications) in a sample of standard healthcare facilities.
Data from standard facilities extrapolated to calculate the requirements for other similar facilities Targets health services available and takes into account current treatment levels o may reflect financial / administrative constraints in existing healthcare system
2) Service-based method
Example: Total annual estimated morphine requirement for country x Type of Facility
Regional Cancer Center Nat’l Cancer Center Hospice
Total number of facilities in country
5
Expected number of patient contacts at all facilities
90,000
Avg. morphine consumption per 1,000 patient contacts (at standard facility)
5 kg
Total requirement per facility type
450 kg 1 10 40,000 50,000 4.375 kg 6 kg 175 kg 300 kg
Total
925 kg
2) Service –based method
Appropriate to use when: Limitations:
prescribing, administering and dispensing patterns in standard facilities are rational, pattern of morbidity in standard facilities is representative of the region/country detailed data on patient morbidity and standard treatment guidelines are not available.
may not take into account medical needs of patients that cannot be met due to constraints of existing health system, inappropriate patterns of prescribing, administering, dispensing in standard facilities will be perpetuated in calculations, and limitations of healthcare system (frequent stock outs) may make it difficult to select valid standard facilities
3) Morbidity –based method
Based on frequency of diseases and health problems (morbidity) and on accepted treatment norms Advantage – draws attention to magnitude of the health problem, (i.e., unrelieved pain) Disadvantage – will likely overestimate the quantities that would actually be consumed
Morbidity-based Estimate for Morphine:
example standard treatment norm
For Cancer patients: # annual deaths x 80% requiring EOL care with oral morphine x 90 days x 60-75mg per day For AIDS patients: # annual deaths x 50% requiring EOL care with oral morphine x 90 days x 60-75 mg per day

3) Morbidity-based method
Example: morphine requirement for late-stage HIV/AIDS pts. in country x Sample Facility
Nat’l Referral hospital with PC unit Regional hospital with PC unit Hospice with home based care Total
No. of late-stage cancer patients Total No. of facilities in country
1,200 1

600 6,075 mg 800 500 5 10 4,000 5,000 2,000 2,500 6,075 mg 6,075 mg
Total qty. of morphine consumed by all late-stage HIV/AIDS patients
3.65 kg 12.15 kg 15.19 kg 30.99 kg
3) Morbidity-based method
Example: morphine requirement for late-stage HIV/AIDS and Cancer pts. in country x
Total: late-stage cancer patients Total: late-stage HIV/AIDS patients GRAND TOTAL
31.59 kg 30.99 kg 62.58 kg
3) Morbidity –based method
Appropriate to use when:
patterns of data on past use are unavailable or unreliable, health services are rapidly changing or new, accurate and complete data on morbidity are available, standard treatment norms have been developed, and promoting a change towards more rational prescribing (according to standard treatment norm).
Limitations:
Healthcare infrastructure may not have the capacity to treat all morbidity if standard treatment norms are not followed, calculated requirements will not match their use For accuracy, need to have complete morbidity data and standard treatment guidelines.
Considerations for ensuring accurate Estimates
Goal: To ensure that opioids are safely distributed to patients receiving medical treatment and to avoid large unused inventories and diversion: • Is there an adequate infrastructure to support the use of medications?
• Will medicines be appropriately stocked, distributed, prescribed, and dispensed?
• Are there trained health care professionals willing to prescribe?
• Are there guidelines for safe handling of controlled medicines?
What can countries do to improve their estimates system?
Decide on appropriate method to develop Estimated Requirement Implement the method Communication between National Competent Authority and Health Professionals
Conclusions
Estimates are Single Convention obligation Government responsibility for calculating estimated requirements to submit annually to INCB Supplementary Estimates are possible New Guide from INCB/WHO offers information on responsibilities and 3 suggested methods Important to consider current capacity of healthcare infrastructure

Estimates: Questions for Discussion
• Have the estimates been adequate to satisfy actual needs for pain management? • What sources of information are used?
• Has the method been evaluated? • How could the method be strengthened?
Guatemala
• Since 2006, oral morphine had not been available in public hospitals • Fellow working to improve distribution of morphine supply from Guatemala City to regional hospitals in rural areas, including training and preparation of paperwork to introduce new supply of oral morphine • In early 2009, requested by Government to assist with calculating national estimated requirement for morphine
Guatemala
• Initially, looked at total population that would need oral morphine for pain relief – proposed to increase estimate to cover 50% of those in need • WHOCC and IAHPC colleagues cautioned against this approach, advised fellow to consider actual need and safe distribution of morphine first • Ultimately considered how many patients were currently being cared for by palliative care units in the country and arrived at a more realistic estimate for morphine
