Introduction: G6PD deficiency is one of the most prevalent genetic diseases in Lebanon (1% in Lebanese males). Easy and effective screening methods exist to detect this deficiency early in newborns.
Objective: To assess the cost-effectiveness of G6PD deficiency screening in the routine work-up of every male newborn in Lebanon.
Methods: Of 299 babies with G6PD deficiency detected between 1999 and 2004, 139 (46.5%) were located, contacted, and surveyed for their experience of acute anemia crises.
Results: A previous community survey had indicated a 77.8% risk for an acute anemia crisis necessitating hospitalization in unscreened patients, most often associated with consuming fava beans raw or in combination products. In contrast, only 5 (3.8%) of the 139 screened G6PD-deficient babies had ever developed a severe acute anemia crisis. The risk for hospitalization following a crisis had thus been reduced by 95% among patients screened for G6PD deficiency, compared to those unscreened. The estimated mean cost of each hospitalization, which lasts on average 7 days, is 1450 USD. The cost of screening is about 3 USD. The analysis indicates that, given the current prevalence of the deficiency and the reduction in hospitalization rates associated with knowing one's status, the cost of systematic screening is about 2.58 times lower than that of anemia-related hospitalizations in an unscreened population.
Conclusion: The efficiency of routinely testing evidenced here supports changes in screening policies for boys.
