ReviewVenous thromboembolism: a collaborative quality improvement model for practitioners, hospitals, and insurers.
Venous thromboembolism (VTE) carries significant morbidity and mortality and affects a large portion of hospitalized patients. VTE prophylaxis is rated by the Agency for Healthcare Research and Quality as the most effective of 79 patient safety practices it assessed in 2001. ⋯ The CQIs are uniquely structured to catalyze hospitals and practitioners to become self-optimizing. In this review, we describe the model BCBSM/BCN and participating Michigan hospitals have developed to improve the prevention and diagnosis of VTE for patients in the state of Michigan.

Comparative StudyEvaluation of dose requirements for prolonged bivalirudin administration in patients with renal insufficiency and suspected heparin-induced thrombocytopenia.
Bivalirudin, a direct thrombin inhibitor, is indicated for patients with suspected heparin-induced thrombocytopenia (HIT) with anticipated percutaneous coronary intervention (PCI). Data is limited on dose selection among patients with renal insufficiency, particularly with prolonged infusion durations. The study cohort comprised 73 patients with renal dysfunction who received bivalirudin for suspected HIT with or without acute coronary syndrome. ⋯ When eGFR was calculated by the modification of diet in renal disease (MDRD; ml/min/1.73 m(2)) formula, the average bivalirudin dose achieving a therapeutic aPTT was 0.07 ± 0.04, 0.12 ± 0.07, and 0.20 ± 0.07 for patients with eGFR between 15-30, 31-60, >60, respectively. The difference between the dose achieving a therapeutic aPTT for patients with eGFR >60 when calculated by MDRD versus CG was completely abolished when obese patients were excluded from the CG cohort. The results of our series of patients with renal dysfunction receiving prolonged duration of bivalirudin in the setting of acute coronary syndrome (ACS) suggests that dose adjustment is safe and should be considered for patients with moderate to severe renal impairment (eGFR < 60 ml/min/1.73 m(2)).
