  1. Differences in the availability of medicines used for chronic and acute conditions in developing countries Alexandra Cameron International Conference on Improving the Use of Medicines (ICIUM) November 2011

  2. Background • Developing countries are undergoing an epidemiological transition from infectious and parasitic diseases to non-communicable diseases • In low- and middle-income countries chronic diseases account for 39% and 72% of all deaths, respectively. • Appropriate pharmacological treatment has been shown to lead to significant reductions in chronic disease morbidity and mortality • Equitable access to essential medicines is a key component of a comprehensive health system response to the prevention and management of chronic diseases • Previous studies have reported low availability of essential medicines, especially in the public sector • The availability of 15 generic medicines used for a range of conditions in 36 developing countries was 38% and 64% in the public and private sectors, respectively (Cameron et al, 2009) • Several studies have shown similar results for medicines used to treat chronic diseases. • No study to date has investigated whether medicines for chronic diseases are less available than medicines in other therapeutic categories.

  3. Hypothesis and research objective • Hypothesis: in countries with weak health systems that have historically focused on infectious diseases, medicines for chronic diseases are less available than medicines used to treat acute illness.   • Objective: to investigate whether differences exist in the availability of medicines used for chronic conditions compared to those used for acute conditions, in developing countries.

  4. Methodology • Data on medicine availability obtained from 50 facility-based surveys conducted in 40 developing countries using WHO/HAI standard methodology. • Medicines included in WHO/HAI surveys selected for international comparability as well as local relevance • 30 medicines included: 15 most-commonly surveyed medicines for each of acute conditions and chronic diseases. • All medicines included in any WHO/HAI survey classified as acute or chronic • Alternate strengths of the same medicine combined when used for same indication • Frequency of inclusion of each medicines in the 50 surveys was calculated to identify the top 15 medicines in each category

  5. Methodology (2) • % availability of each medicine was compiled for both originator brand and generic medicines, in both public and private sectors. • Availability of originator brands and generics was also combined on a facility-by-facility basis to determine the overall availability (any product type) of each medicine. • Gap between availability of acute and chronic medicines calculated as the difference in availability of the two baskets of medicines. • Mean availability of chronic basket was disaggregated by therapeutic class and compared to the mean availability of the acute basket. • Results aggregated by World Bank Country Income Group and WHO Region.

  6. Results

  7. Study limitations • Availability may not reflect average over time • Public sector availability may be influenced by national EML and levels of care • Choice of medicines included in each basket • Country variations in use • Important treatments (e.g. insulin) missing • lack of a clear distinction between acute and chronic indications for some medicines • Variations in time since patent expiry

  8. Conclusions and policy implications • Availability of acute and chronic medicines both sub-optimal in the public sector • Significant differences in public sector availability of medicines for acute and chronic conditions • Gaps between acute and chronic not the result of low patient demand due to lower disease burden or other factors. • Increased attention to chronic diseases is needed in the public sector, especially in LICs and LMICs and especially in Africa

  9. Conclusions and policy implications (2) • Low availability can have many causes: • lack of resources or under-budgeting • inaccurate forecasting • inefficient procurement / distribution • low demand/slow-moving products • Low public sector availability can be addressed through and adequate, equitable, and sustainable financing, e.g. social health insurance with outpatient medicines benefit that includes medicines for NCDs. • Improved purchasing and/or distribution efficiency can also improve availability • Schemes to make chronic disease medicines available in the private sector at subsidised prices
