Objective: To estimate the economic burden of needlestick injuries (NSIs) among healthcare workers (HCWs) in China.
Design: A model was built to evaluate the economic burden of NSIs.Methods: The cost model was developed from a societal perspective, including both direct and indirect costs, with lifetime horizon. The direct costs were categorized into infection prevention and treatment of infections. The indirect cost included productivity loss of both HCWs and his/her family members due to the blood-borne infections. Sub-group analyses were conducted to estimate the cost per NSI when the source patient (SP) was confirmed with hepatitis B virus/hepatitis C virus/human immunodeficiency virus (HBV/HCV/HIV) infection. One-way and probabilistic sensitivity analyses were conducted for all parameters to examine the robustness of the result.
Results: The model projected a total cost of ¥699 for each NSI (direct and indirect cost were ¥553 and ¥146, respectively). The cost per NSI when the SP was confirmed with HBV/HCV/HIV was ¥4,238, ¥18,404, and ¥6,152, respectively. The total economic burden of NSIs among HCWs in China was estimated to be ¥5.8 billion, and about half of the cost was associated with NSIs in nurses, at ¥2.8 billion.
Limitations: This study did not incorporate the costs of litigation/psychological, and the prevalence of the infections was based on the general population, so the actual costs per NSI may be underestimated. More real-world studies of treatment cost about HBV/HCV are needed to further supporting this study.
Conclusions: The economic burden of NSIs among HCWs in China is substantial. Comprehensive NSI prevention programs, including implementation of safety needles and devices, have high potential for healthcare institutions to achieve downstream cost savings and cost offsets.
