RESUMO
Background: The American Heart Association has a call to action to reduce hospital acquired venous thromboembolism (HA-VTE) by 20% by the year 2030. There is increasing recognition that quality improvement initiatives for VTE reduction should focus on reducing potentially preventable HA-VTE. The objective of our study was to determine what proportion of HA-VTE events are potentially preventable. Methods: This was a retrospective, single center pilot study of 50 patients with HA-VTE. Seven preventability factors were identified with a focus on VTE prescription and administration. Data were extracted through chart review using a systematic data collection form. The primary endpoint was the proportion of patients with potentially preventable HA-VTE. Descriptive statistics were used. Results: The median age was 66 years with an admission VTE risk level of moderate-high in 94%. Potentially preventable HA-VTE was found in 40% of cases. Missed doses occurred in 29.8% with a median of 2 missed doses and a range of 1 to 20. Patient refusal was the most common reason for missed doses in 71%. Delays in initiation occurred in 12.7%. Sixty percent of those on mechanical prophylaxis only had nonadherence. Conclusion: Forty percent of HA-VTE cases were potentially preventable. Missed doses was the most common preventability factor identified with patient refusal accounting for most missed doses.
RESUMO
BACKGROUND: The University HealthSystem Consortium (UHC), a national hospital engagement network (HEN), establishes health-system metrics to assess and improve quality of care. In 2012, a metric for inpatient anticoagulant hemorrhage was developed. The utility of this metric to improve anticoagulation care has not been assessed. OBJECTIVE: To identify opportunities to improve anticoagulation safety through the use of a HEN metric for inpatient anticoagulant-associated hemorrhage. METHODS: This was a single-center, retrospective, observational study of metric identified patients with presumed inpatient anticoagulant hemorrhage. Records were reviewed to confirm anticoagulant hemorrhage and identify bleed site and severity. A structured process was used to assess bleed preventability and subsequently identify opportunities for improving care. Each bleed was reviewed by 2 investigators. RESULTS: Anticoagulant hemorrhage was confirmed in 85.9% (61/71) with heparin infusion the most common anticoagulant. Patients were primarily medical, with a mean age of 72.7 ± 15 years. The most common bleed sites were gastrointestinal (24.6%) and retroperitoneal (21.3%). Major bleeding occurred in 60.7% (37/61). Anticoagulant hemorrhage was preventable in 18% (11/61) of cases with heparin protocol noncompliance the most common cause of a preventable bleed. Several opportunities for improving heparin infusion therapy were recognized and protocol changes were implemented. CONCLUSIONS: The UHC metric accurately captures inpatient anticoagulant-associated hemorrhage the majority of time. The UHC metric on anticoagulant-associated hemorrhage can be a useful part of a health system's overall plan for the safe use of anticoagulants in the hospital setting.

Data comparing the patient characteristics, management and outcomes for dabigatran versus warfarin major bleeding in the practice setting are limited. We performed a retrospective single health system study of atrial fibrillation patients with dabigatran or warfarin major bleeding from October 2010 through September 2012. Patient identification occurred through both an internal adverse event reporting system and a structured stepwise data filtering approach using the International Classification of Diseases diagnosis codes. Thirty-five dabigatran major bleeding patients were identified and compared to 70 warfarin major bleeding patients. Intracranial bleed occurred in 4.3 % of warfarin patients and 8.6 % of dabigatran patients. Dabigatran patients tended to be older (79.9 vs. 76 years) and were more likely to have a creatinine clearance of 15-30 mL/min (40 vs. 18.6 %, p = 0.02). Over one-third of dabigatran patients had an excessive dose based on renal function. More dabigatran patients required a procedure for bleed management (37.1 vs. 17.1 %, p = 0.03) and received a hemostatic agent for reversal (11.4 vs. 1.4 %, p = 0.04). Dabigatran patients were twice as likely to spend time in an ICU (45.7 vs. 27.1 %, p = 0.06), be placed in hospice/comfort care (14.3 vs. 7.1 %, p = 0.24), expire during hospitalization (14.3 vs. 7.1 %, p = 0.24), and expire within 30-days (22.9 vs. 11.4 %, p = 0.28). In a single hospital center practice setting, as compared to warfarin, patients with dabigatran major bleeding were more likely to be older, have renal impairment, require a procedure for bleed management and receive a hemostatic agent. Patients with dabigatran major bleeding had an excessive dose for renal function in more than one-third of cases.

OBJECTIVES: To identify patient characteristics, bleed management, and bleed outcomes in patients experiencing an apixaban major bleeding event and to identify opportunities to improve the safe use of apixaban. METHODS: This retrospective single health-system study identified apixaban patients experiencing a major bleeding event between January 2013 and May 2016 through electronic medical record review. Patient characteristics, bleed management, and outcomes were extracted in those with a confirmed major bleed assessed by the International Society on Thrombosis and Haemostasis criteria. RESULTS: Fifty major bleeding events occurred in 49 patients (79 ± 9.8 years). Patient characteristics included history of hypertension (94%), anemia (68%), and concomitant antiplatelet use (68%). Gastrointestinal bleeding occurred in 72% of patients and intracranial hemorrhage in 14% of patients. Packed red blood cells (PRBCs) were utilized in 82% of patients and reversal agents were administered to 6% of patients. Mortality during the hospital admission for the bleed was 0%. Anticoagulation was held at discharge in 64% of patients and remained held at 30 days in the majority of patients. Of those on concurrent aspirin therapy, an appropriate indication was not found in 64.7% of patients. CONCLUSIONS: Patients with major bleeding were elderly and frequently on inappropriate concomitant antiplatelet therapy. The majority of patients were managed with PRBC transfusion. More than half of patients had anticoagulation therapy held at discharge. Concerns with prescribing and patient management were identified leading to recommendations for improving the safe use of apixaban therapy.

Rivaroxaban, the first oral direct factor Xa inhibitor, was approved for stroke prevention in nonvalvular atrial fibrillation in 2011. Limited data are available regarding major bleeding in a clinical practice setting. The purpose of this study is to describe the patient characteristics, management, and outcomes of major bleeding events in patients receiving rivaroxaban for atrial fibrillation. This retrospective, single health system study identified patients with rivaroxaban having a major bleeding event between July 2011 and June 2014. Patients were identified through adverse event reporting or by cross-referencing rivaroxaban with International Classification of Diseases, Ninth Revision diagnosis codes for atrial fibrillation and hemorrhage, with and without transfusion. A total of 60 patients were identified. The mean age of patients was 80.3 ± 7.4 years. The most common bleed sites were gastrointestinal (63.3%) and intracranial (26.7%). Higher dose than recommended based on renal function was present in 35% of patients and concurrent antiplatelet therapy occurred in 70%. Activated prothrombin complex concentrate was utilized in 30% of patients and recombinant factor VIIa in 6.7%. A procedure or surgery was performed for bleed management in 10 patients. Anticoagulation was held at discharge in 76% of patients. A total of 6 patients died during hospital admission, 5 of whom experienced an intracranial hemorrhage. In conclusion, patients experiencing a rivaroxaban major bleeding event were elderly, often renally impaired, and receiving concurrent antiplatelet therapy. In-hospital mortality was 10%. The majority of patients (76%) had anticoagulation therapy held at discharge.
