Challenges in implementing government-directed VTE guidance for medical patients: a mixed methods study

Understanding patients' care barriers in the treatment of venous thromboembolism

Venous thromboembolism (VTE) is a major health care problem. There are common barriers to quality healthcare but are these barriers the same for VTE patients? A national online survey was administered to adults who had experienced a recent VTE event. The survey assessed perceptions of VTE care barriers: (1) Difficulty to meet healthcare costs related to VTE care; (2) difficulty to meet costs for VTE prescription medications; (3) difficulty with transportation to get VTE care; and (4) the degree of support of others needed to get VTE care. Each question was correlated with patient demographics including income level, place of residence, current work status, and health insurance; care related patient harms experienced with the VTE episode; number of lifetime VTE events; beliefs concerning VTE outcomes, and oral anticoagulant therapy type. Logistic regression analysis was used to determine the effect of independent variables on barriers to VTE care. Approximately 30% of VTE patients reported at least one significant barrier to VTE care. Patients rated healthcare costs and VTE prescription medication costs mildly difficult. The odds of reporting barriers were positively associated with the number of DVTs experienced in the previous 2 years. VTE-related depression was also moderately associated with increased odds of reporting significant VTE care barriers. Nearly 1 in 3 VTE sufferers reported significant barriers to VTE care, with healthcare costs and VTE medication costs being the most common. Efforts to identify patients who may experience barriers should be sought early in care.

Prophylaxis of Venous Thromboembolism in Geriatric Settings: A Cluster-Randomized Multicomponent Interventional Trial

OBJECTIVES

To evaluate the efficacy of an intervention on the practice of venous thromboembolism prevention.

DESIGN

A multicenter, prospective, controlled, cluster-randomized, multifaceted intervention trial consisting of educational lectures, posters, and pocket cards reminding physicians of the guidelines for thromboprophylaxis use.

SETTINGS

Twelve geriatric departments with 1861 beds total, of which 202, 803, and 856 in acute care, post-acute care, and long-term care wards, respectively.

PARTICIPANTS

Patients hospitalized between January 1 and May 31, 2015, in participating departments.

MEASUREMENTS

The primary endpoint was the overall adequacy of thromboprophylaxis prescription at the patient level, defined as a composite endpoint consisting of indication, regimen, and duration of treatment. Geriatric departments were divided into an intervention group (6 departments) and control group (6 departments). The preintervention period was 1 month to provide baseline practice levels, the intervention period 2 months, and the postintervention period 1 month in acute care and post-acute care wards or 2 months in long-term care wards. Multivariable regression was used to analyze factors associated with the composite outcome.

RESULTS

We included 2962 patients (1426 preintervention and 1536 postintervention), with median age 85 [79;90] years. For the overall 18.9% rate of inadequate thromboprophylaxis, 11.1% was attributable to underuse and 7.9% overuse. Intervention effects were more apparent in post-acute and long-term care wards although not significantly [odds ratio 1.44 (95% confidence interval 0.78;2.66), P = .241; and 1.44 (0.68, 3.06), P = .345]. Adequacy rates significantly improved in the postintervention period for the intervention group overall (from 78.9% to 83.4%; P = .027) and in post-acute care (from 75.4% to 86.3%; P = .004) and long-term care (from 87.0% to 91.7%; P = .050) wards, with no significant trend observed in the control group.

CONCLUSIONS/IMPLICATIONS

This study failed to demonstrate improvement in prophylaxis adequacy with our intervention. However, the intervention seemed to improve practices in post-acute and long-term care but not acute care wards.
