Quality of Life of Patients Receiving Warfarin Therapy at a Tertiary Care Centre in Indonesia Using DASS (Duke Anticoagulation Satisfaction Scale).

Purpose: This study aimed to examine the quality of life of patients receiving warfarin therapy at Dr. Hasan Sadikin Central General Hospital, and its relationship with demographic factors.

Patients and methods: The procedures started with the submission of a study permit, followed by validation of the Duke Anticoagulation Satisfaction Scale (DASS) questionnaire. In addition, the validated questionnaire was completed by the participants, and significant variables were analyzed using the chi-square method for multivariate analysis.

Results: The results showed that the questionnaire was valid and could be used for further analyses. Among the 88 selected participants, 52 and 36 had scoring categories <56.266 and 56.266 ≤ x ≤ 143.734, respectively, with no patients having a scoring category > 143.734. In addition, participants with low education and aged ≥ 52 years were 4.916 and 3.161 times more at risk of having quality of life score of 56.266 ≤ x ≤ 143.734, respectively. Based on the results, the average quality of life score of patients was 59.66. Participants with low educational levels and those aged ≥ 52 years were at a higher risk of having quality of life score of 56.266 ≤ x ≤ 143.734.

Conclusion: In summary, a lower quality of life score was linked to increased comfort and satisfaction among patients receiving warfarin treatment. Additionally, these patients experienced fewer feelings of limitations and inconveniences related to their treatment plans.
