Strengths and Limitations of Market Intelligence Data for Pharmaceutical Policy Analysis in LMIC ICIUM 2011 - Third International Conference for Improving Use of Medicines Antalya, November 2011
Agenda • Introduction to: • Volume data • Medical Data • Sampling and projection • Data quality process • Summary What do we collect, why do we collect it in that way & where we collect it
Volume data: Collected from different parts of the supply chain, depending on the country
20% 72% 71% 18% 70% 1% 7% 6% 3% 5% 1% 2% 1% ThailandChannels ofdistribution Updated 2010 Agents/distributors Manufacturers Own distributor Wholesalers Healthcenters & private clinics Retail drugstores type A & B Non drugstoreoutlets General hospitals Special hospitals Consumers Market covered by TLPI Market covered by TLHI Status 2009 Results are based on information provided by 27 manufacturersthat represent 30% of the market share.
Ecuador – multi-source sampling • Data sources: • MF data (unprojected) • Distributor data (unprojectable) • Wholesaler data (projectable) • Chain pharmacies (unprojectable) • Independent pharmacies (projectable)
Data points Information typically captured (volume data) Derived characteristics (EPhMRA ATC, Manufacturer, Corporation, Molecule, Salt, Launch, Brand/Unbranded, Volume (Units, SU or Kg)
Information captured in medical data No in-patient Diagnosis Patient demographics • ICD10 codes • Doctorwording • Co-diagnoses • Treated/untreated • Age • Sex • Smoker/non-smoker • Insurance Doctordemographics Therapy • Age, sex • Speciality • Year qualified • University • Region • Productprescribed • Desiredeffect • Co-prescription • ATC, NDF • Dosagedata
Sampling and projectionKey elements of sampling concepts The right balance determines the relevance of our measurements
Sampling and projectionSample design stratification Weighting variables + Geospatial
Data quality – sampling error components Random Error:Unviewed ≠ sample • Sample size • Stratification • Selection Systematic Error =data collection • Non-response • Incompletereporting • Reporting time • Reporting quality
Data quality: Sample design Brazil
IMS Annual Validation Studies (for sales data) • Since 1964, in collaboration with industry associations (EPhMRA, BPIRG), we conduct annual comparisons with our customers, contrasting IMS data estimates with actual industry sales. • These ‘validation studies’ are carried out in more than 60 markets with ~ 2,200 pharmaceutical companies, covering more than 70,000 product forms. • The results are published once a year in the IMS Annual Report on Quality Assurance – ACTS. • All validation studies follow the same uniform procedure and reporting is standardized in order to allow cross-country comparisons and easy reading.
Bias (only for sales data) Average over/underestimation of the real market performance: Total IMS units of all validated product forms Total real units of all validated product forms Example: Pack IMS Units Real Units R-Value A 1,000 900 1.111 B 1,200 1,500 0.800 Bias = -3.4% C 4,000 3,800 1.053 D 6,500 7,000 0.929 E 7,200 7,400 0.973 Total 19,900 20,600 0.966

Share of total volume used in validation comparison (2009) Latvia = 27% Malaysia = 29% Mexico = 36% Turkey = 66% Venezuela = 72%
Limitations of data utilization • Prices • Collected only at one point in supply chain • Generally list prices • Discounting not always known or able to be taken into account • Coverage • Not all channels, and samples of channels • Often combines public and private in same audit • Accuracy varies by product size for sample-based data • Almost all audits are sample based • Inpatient prescribing not available • Cross country comparisons using medical data needs to bear in mind specialty mix
Reimbursement policy assessment and impact • Generic market evolution • Generics policies and impact • Pricing policy impact on volume • Potential savings (using country own price data) • Medicines shortages • Quality of care initiatives assessment and impact • Unwarranted variations in volumes • Pharmaceutical “gaps” • Usage by indication • Exposure studies • Adherence to guidelines • WHO/National Essential Drug List • Therapy area formularies e.g. antibiotics
