The obese population’s views on the symptoms and risks of chronic venous insufficiency - 2 (OBVIOUS-2) cross-sectional survey

IntroductionIndividuals with high body mass index (BMI) are more likely to have symptomatic LLVD than age matched populations with normal BMI. National priorities in venous disease set by the James Lind Alliance focus on improving access to healthcare and patient education. The aims of this study are to determine patient knowledge and potential burden of LLVD in a population of patients attending a UK, regional weight management service.MethodsA postal questionnaire containing 12 questions relating to LLVD and obesity was distributed to the active list of patients under the weight management medical service at Dudley Group of Hospitals between May 2022-23. Respondents were provided with a stamped, addressed envelope to return the questionnaire. Ethical approval was granted by the Hampshire Research & Ethics Committee.ResultsSome 367 questionnaires were distributed to patients currently enrolled in specialist weight management services. 103 complete responses were received (28%), Most patients were between 50 and 70 years of age. 25% of patients already had a formal diagnosis of LLVD, with a further 84 (82%) reported signs or symptoms which may be related to LLVD. Almost half (49/103, 48%) had concerns over their skin quality with a similar proportion (25/103, 51%) having sought medical help. The majority (71/103, 69%) were unaware of the association between obesity and LLVD. Twelve participants had education regarding simple adjuncts designed to improve symptoms and/or prevent ulceration (emollients, dressings, stockings, or leg elevation). Four participants had previously undergone treatment for varicose veins.ConclusionIn a population of patients accessing weight management services, we have demonstrated that a quarter of patients have already received a diagnosis of LLVD, however there is for a greater undiagnosed burden of LLVD in part due to lack of patient and possibly clinician awareness.
