Cost-effectiveness analysis

We divided the economic burden of thalassemia detection intodirect,indirectandintangiblecosts, since it covered material cost, labor cost and capital cost, including the cost of patient care and non-patient careactivities. Lots of investigation had reported the cost of major and intermedia thalassemia in China1-3.The excepted lifespan for a normal individual is 75 years in China. The estimated annual per capitadirect cost forthalassemia major and intermedia is ¥43058.66; the estimated annual percapitaindirectcost of thalassemiais ¥20474.51; and the intangiblecost is estimated at¥302466.67(usually ¥138200.00-¥300000.00). The total economic burden ((direct cost + indirect cost)*75+ intangiblecost ) of thalassemia major and intermedia is estimated nearly $760000.00 dollars2. The cost-effectiveness ratio (CER) of finding a carrier of thalassemiawas ¥560.00,by traditional hematological screening methods (Blood routine examination andHemoglobin electrophoresis analysis first, and then hemoglobin gene test to confirm) in contrast to ¥200.00 by NGS screen based on our study. The incremental cost-effectiveness ratio (ICER) is a statistic used in cost-effectiveness analysis to summarize the cost-effectiveness of a health care intervention and could be estimated as ICER=(C1-C0)/(E1-E0), where C1 and E1 are the cost and effect in the intervention group and where C0 and E0 are the cost and effect in the control care group.In this study: C1=NGS cost of all samples, E1=Numbers of thalassemiacarriers detected by NGS, C0=Traditional hematological screening cost of all sample + kit testing cost of union set of the traditional hematological screening, E0= Numbers of thalassemiacarriers detected by kit testing after the MCV+MCH, HbA2 parallel combined detection screen. The ICER of NGS & traditional hematological screeningis -2920. NGS screening not only reduces screening costs, but by early diagnosis also avoids the economic burden of thalassemia major and intermedia among infants estimated to cost nearly one million dollars over their lifespan.
