Venous thromboembolism: exploring incidence and utility of screening in individuals with dual diagnosis

Objectives

The development of venous thromboembolism (VTE) is a common complication following spinal cord injury (SCI) and brain injury (BI), leading to significant morbidity and mortality. The purpose of this study was to explore the incidence of VTE in patients with the dual diagnosis (DD) of SCI and concomitant BI using ultrasonography.

Design

Retrospective study.

Setting

Acute rehabilitation hospital.

Participants

Thirty-one individuals admitted for DD rehabilitation who were routinely screened for VTE with ultrasound on admission.

Interventions

Not applicable.

Main Outcome Measures

Retrospective chart review was performed to identify whether patients were found to have DVT or PE at the following three time points: in acute care prior to admission to rehabilitation, at time of admission diagnosed via screening examination, and after admission to rehabilitation during the inpatient stay via post screening examinations. Retrospective chart review was also performed to identify incidence of bleeding.

Results

67.7% of individuals were found to have DVTs at any timepoint. Of these DVTs, 22.6% were identified in acute care, 48.4% on admission to rehabilitation, and 16.1% during the course of rehabilitation stay. Of those who were placed on therapeutic anticoagulation due to admission diagnosis of VTE, 25% developed recurrent DVT and 12.5% had bleeding complications. No cases of PE were observed in this study population.

Conclusions

This study found a high incidence of DVT for the DD population at all three timepoints with a high proportion identified via screening ultrasonography on admission to rehabilitation. Further research is needed to investigate the incidence of VTE and utility of screening ultrasonography in this population.
