ARMADANS GIL, Lluís et al. Safety-engineered devices to prevent percutaneous injuries: cost-effectiveness analysis on prevention of high-risk exposure. Gac Sanit [online]. 2006, vol.20, n.5, pp. 374-381. ISSN 0213-9111. http://dx.doi.org/10.1590/S0213-91112006000500006.
Objective: To assess the efficiency of the replacement of several medical devices by engineered sharp injury (SI) prevention devices (ESIPDs). Methods: The cost-effectiveness ratios of the replacement of medical devices in use by ESIPDs were estimated: their purchasing costs and the direct costs of sharp injury care were taken into account; the number of SI avoidable by each ESIPD was estimated from the 252 occupational SI notified by healthcare workers at a 1,300 bed hospital from March 2002 to February 2003. The relationship between ESIPD additional costs and the number of high-risk SI was estimated (SI were classified as high-risk if they met two or more of the following criteria: moderately-deep or deep injury, injury with a device previously inserted in an artery or vein, or with a device exposed to blood). Results: ESIPDs order according to cost-effectiveness ratio: safety needle for implanted ports (-2.65 /SI avoided), followed by syringes with protective shield (869.79 /SI), resheathable winged steel needles, needleless administration sets, and short catheters with protective encasement. ESIPDs order according to relationship between additional costs and number of high-risk sharp injuries avoided: safety needles for implanted ports, followed by winged steel needles, hypodermic syringes, short catheter and needleless administration sets. Conclusions: Savings in SI care outweigh additional costs of certain ESIPDs. Cost-effectiveness analysis is useful in assigning priorities; however the risks of SI by every device must be taken into account.
