Risk factors for deep vein thrombosis and pulmonary embolism: a comparative study between acute hospital care and mental health inpatient settings for older people

Abstract

Purpose This study aims to establish if risk factors for venous thromboembolism (VTE) in older hospitalized psychiatric patients differ from geriatric inpatients and if the current risk assessment tools being used are suitable. Design/methodology/approach The authors undertook a single centre retrospective review of 75 records for presence of predetermined risk factors. In total, 55 discharged patients with thrombotic events within geriatric settings were compared with 20 from mental health settings. Differences in risk factors were determined using t-test and Fisher’s exact test. Findings VTE patients in geriatric units were older and had reduced mobility. Psychiatric patients were more likely to be dehydrated and treated with psychotropics. Whilst rates of VTE screening were comparable in both settings, geriatric inpatients were more frequently prescribed thromboprophylaxis. Research limitations/implications Older psychiatric inpatients differ from those in medical/surgical settings in their profiles and risk factors for VTE. Approaches for VTE risk management also differed. Practical implications The study suggests the need for VTE screening tools and treatment protocols specific to older psychiatric settings. Social implications Targeted approaches may improve outcomes specific to each group. Originality/value To the best of the authors’ knowledge, this is the first attempt in comparing VTE risk factors across acute physical health care and mental health settings.
