MOYA-SALAZAR, Jeel; PIO-DAVILA, Liz  and  DIAZ R, Rommel. Depletion of blood supply and cost due to indeterminate donations at the Guillermo Almenara Irigoyen National Hospital. Horiz. Med. [online]. 2017, vol.17, n.1, pp.31-37. ISSN 1727-558X.

Objective: To evaluate the depletion of blood supply and the cost due to indeterminate donations at Hospital Nacional Guillermo Almenara Irigoyen during 2014. Materials and methods: A retrospective cross-sectional study and a cost-utility analysis were conducted in donations showing results in the gray zone (sample value/cutoff value between >0.85 and <1) after a serological screening of seven infectious markers (HIV, HBsAg, HBcAb, HCV, HTLV-1/2, syphilis and Chagas disease) and the simultaneous determination of the HIV Ag/Ab combo by means of a fourth generation ELISA. Data was encoded and tabulated using the e-Delphyn® system. The cost-utility analysis was performed considering the current exchange rate. Results: Out of 9,560 donations, 20.7% (1977 donations) showed results in the gray zone which caused a loss of 863.9 liters of blood and USD 92,640. The highest and lowest rate of seroprevalence were observed in HBcAb with 10.18% (973 indeterminate test results) and anti-HIV with 0.39% (47 indeterminate test results), respectively (p<0.05). No significant differences were found between the anti-HIV y HIV Ag/Ab combo screening methods (p=0.776). Conclusions: It was demonstrated that more than 800 liters of discarded blood generated a more than USD 90,000 cost due to indeterminate donations causing economic damages to the hospital budget and a depletion of blood supply available for patients at Hospital Nacional Guillermo Almenara Irigoyen.
