An Evaluation of Interprofessional Patient Navigation Services in High Utilizers at a County Tertiary Teaching Health System.

EXECUTIVE SUMMARY: The Affordable Care Act holds health systems accountable for patient outcomes. Patients with low socioeconomic status are at highest risk of lacking a primary care provider, receiving lower quality of care, and being readmitted. These patients also have elevated risks of all-cause readmissions and death after discharge. The purpose of this study was to determine if an interprofessional patient navigation program (PNP) decreases emergency department (ED) visits and hospital admissions for these high utilizers of care, thus promoting the implementation of PNPs in other healthcare settings. We performed a retrospective, single-centered, chart review of patients who were enrolled in the PNP. We compared utilization, including ED visits and hospital admissions, for patients two years prior to enrollment to their utilization after enrollment. We found significant reductions in hospital utilization through patient navigation in the predominantly indigent, culturally diverse population of high utilizers of the healthcare system. In addition, our investigation of costs associated with implementing a PNP indicates the potential for cost avoidance.

Increased Enoxaparin Dosing for Venous Thromboembolism Prophylaxis in General Trauma Patients.

OBJECTIVE: To review the evidence regarding increased enoxaparin dosing for venous thromboembolism (VTE) prophylaxis in the general trauma patient population. DATA SOURCES: A search of MEDLINE databases (1946 to October 2016) was conducted using the search terms enoxaparin, thromboembolism prophylaxis, venous thromboembolism, trauma, anti-factor Xa, and weight-based dosing. Additional references were identified from a review of literature citations. STUDY SELECTION AND DATA EXTRACTION: Search results were limited to English-language studies conducted in humans. Trials that included only obese patients or nontrauma patients were excluded. DATA SYNTHESIS: A total of 7 trials (958 patients) explored the use of increased dosing of enoxaparin for VTE prophylaxis in trauma patients. Patients were divided by enoxaparin dosing strategies: standard dosing of 30 mg twice daily (BID; n = 509), higher initial dosing regimen (n = 216), or dosing based on anti-FXa level adjustments (n = 233). The majority of the 42 total VTE events (64.3%) occurred in the standard dosing regimen. Within each group, VTE was reported in 5.3% of patients in the standard dosing group, 3.2% in the higher initial dosing group, and 4% in the anti-FXa adjustment group. Initial subtherapeutic anti-FXa levels occurred in 33% to 92% of standard dose patients and 9% to 39% of higher initial dose patients. The average weight-based dose required to achieve a therapeutic level ranged between 0.43 and 0.54 mg/kg/dose BID. The overall rate of bleeding was low, with 3 incidents (0.37%) reported. CONCLUSION: Standard-dose enoxaparin prophylaxis may not be optimal for the general trauma patient population. Weight-based enoxaparin dosing (0.5 mg/kg/dose BID) is an option in trauma patients considered to be at a lower risk of bleeding complications.
