How does your org prevent RNs from inadvertently increasing heparin dose after holding for critical PTT when post-hold PTT comes back therapeutic or subtherapeutic?
For example, my org's protocol is that if PTT is critical, hold heparin x 1 hr, recheck PTT, and if less than x secs, restart at 3 units/kg/h less than pre-hold dose. However, if post-hold PTT is subtherapeutic, for example, some RNs may misinterpret the protocol (which has been reviewed by human factors engineer) and increase dose, not as intended.
