Michael Mals, 57, underwent a hip replacement at Lutheran General Hospital on Aug. 14, 2008. He was given Coumadin, a blood thinner, to prevent deep vein thrombosis (DVT). Three days later he was transferred to a nursing home for rehab where his INR (international normalized ratio) became supratherateutic and Coumadin was discontinued. In other words, his blood became too thin for his well-being.
Mals was readmitted to Lutheran General Hospital on Aug. 28, 2008 with an elevated INR level, suspected internal bleeding and an elevated white blood count. He was diagnosed with a bleed within the left iliacus muscle and bilateral DVTs. He was restarted on Coumadin, and he returned to the nursing home on Sept. 2.
On Sept. 11, 2008, Mals was readmitted to Lutheran General with elevated INR and anemia, placed on Lovenox anticoagulant therapy and sent back to the rehab facility.
