ObjectiveThe objective of the study was to describe the quality of life (QoL) status and investigate the influencing factors of QoL among patients with deep vein thrombosis (DVT).MethodsA retrospective analysis at a single center was performed, and the clinical data of 161 patients with DVT admitted to West China Hospital of Sichuan University from June 2019 to June 2020 were collected with the Villalta scale, Hospital Anxiety and Depression Scale (HADS), and Chronic Venous Insufficiency Questionnaire (CIVIQ). The relationship between QoL and influencing factors, including characteristics, course of DVT, postthrombotic syndrome (PTS), psychological status, and behaviors, was analyzed by Student’s t-test, analysis of variance and multiple linear regression.ResultsA total of 161 patients who completed all the questionnaires between 2019 and 2020 were included, and 110 patients (68%) were male. The mean QoL score acquired by the CIVIQ scale was 74.18±8.44, and the results showed significant differences between patients of different ages, genders, behaviors and psychological statuses (P < 0.05). Multiple regression analysis showed that age (P = 0.024), negative mood (P < 0.001), CCI index (P < 0.001), PTS (P < 0.001) and regular exercise (P = 0.002) influenced the CIVIQ scale evaluation model, in which exercise regularly was a protective factor for QoL, and age, negative mood, CCI index and PTS were risk factors for QoL.ConclusionThe QoL of DVT patients was impaired and associated with age, mood, CCI index and PTS. Regular exercise is beneficial for improving the quality of life of DVT patients.
