Patients’ perception of long-term, low-molecular weight heparins for cancer-associated thrombosis (CAT): Treatment expectations, convenience, and satisfaction related to patient profile.

Abstract

88 Background: In the TROPIQUE study CAT pts had high expectations for anticoagulant treatment & long-term LMWH was perceived as convenient with high degree of treatment satisfaction. In this study, using the Perception of Anti-Coagulant Treatment Questionnaires (PACT-Q), we assessed the inpact of patient profile on treatment expectations, convenience and satisfaction. Methods: PACT-Q (1&2) were proposed on a voluntarily basis to cancer pts recently diagnosed with symptomatic venous thromboembolism; the global mean scores±SD was correlated to pts characteristics. Results: 269 PACT-Q1 & 139 PACT-Q2 were analysed &135 pts done both of them. In all pts, the highest mean scores were for expectations of symptom relief (4.22±0.9), confidence in preventing clots (3.98±1.04) & importance of simplicity of use (3.94±0.75). For clot prevention men were more confident (4.06±0.81) vs women (3.85±0.88). Expectations of symptom relief was higher in women (4.07±0.98) vs men (3.89±1.09). Importance of ease of use was higher in treated pts (4.27±0.89) vs no therapy (4.00±0.99) & pts with age ≥ 49 (4.46±0.59) vs < 49 years (3.98±1.07). At the end of the study, PACT-Q2 answers showed, an Anticoagulant Treatment Satisfaction scores of 62.9±16.7. 67.2% of pts felt strongly reassured & 48.5% were satisfied with symptom decrease. 69.1% of pts were satisfied / very satisfied with their anticoagulant treatment. Treatment-related side effects were as expected (41.7%), better/much better than expected (45.5%). 80.6% of pts reported higher ease with tinzaparin and 76.2% with other LMWH. According to pts characteristics, satisfaction was higher in men (64.4±17.7) vs women (61.0±15.0), in non-metastatic (64.6±16.9) vs metastatic (61.1±16.2). ECOG (3-4) pts reported lower treatment convenience with higher satisfaction vs ECOG (0-1); 80.0% of ECOG (3-4) pts were satisfied/very satisfied with anticoagulant treatment. 70.0% of ECOG (1-0) patients stated symptom decrease & 80.0 % a feeling of reassurance. Conclusions: pt’s profile influenced positively the perception of long-term LMWH treatment but not the convenience & treatment satisfaction.
