Estimating Tanzania's National Met and Unmet Blood Demand from a Survey of a Representative Sample of Hospitals

Estimating blood demand to determine collection goals challenges many low-income countries. We sampled Tanzanian hospitals to estimate national blood demand. A representative sample based on probability proportional to size (pps) sampling of 42 of 273 (15%) Tanzanian transfusing hospitals were selected. Blood bank registers, patient medical records, and blood component disposition records were reviewed prospectively from June –September 2013 to determine the number of components requested and the number and proportion issued, not issued due to non-availability, and not issued for other reasons.
