title: Venous thromboembolism: patient awareness and education in the pre-operative assessment clinic.
abstract: Each year venous thromboembolism (VTE) causes up to 60,000 deaths in the UK, many resulting from hospital-acquired thromboses following elective surgery. National Institute for Health and Clinical Excellence (NICE) guidelines state that all elective surgical patients should receive verbal and written information pre-operatively regarding the risks of developing VTE. This audit assessed elective surgical patient's prior awareness of VTE and examined how effective targeted patient education during the pre-operative assessment is in increasing this awareness. A 13 point questionnaire designed to assess a pre-operative patient's understanding of topics relating to VTE was provided to consecutive patients identified as being at risk of developing VTE at the end of their pre-operative assessment over a two-week period. A total of 68 questionnaires were completed. Provision of verbal and written information was poor (47 %, n = 32 and 47 %, n = 32 respectively). Despite this, 71 % (n = 48) of patients were aware of the consequences of developing VTE. Many patients correctly identified surgery (71 %, n = 48), immobility (71 %, n = 48) and being overweight (68 %, n = 46) as risk factors, but not dehydration (47 %, n = 32). Lack of awareness regarding personal methods to reduce the risk of developing a VTE post-operatively (24 %, n = 16) and potential side-effects of medical prophylaxis (32 %, n = 22) were also identified. Many patients already possess an awareness of VTE, however, specific knowledge regarding its risk factors and methods of prevention is lacking. Provision of targeted written and verbal educational information during the pre-operative assessment is an effective method of increasing a patient's awareness of these topics. Increased patient awareness may empower patients in their post-operative recovery and enable them to make more informed decisions regarding VTE prophylaxis options.
