• Study description:
  The present study has been designed to describe the HRQoL in patients with non valvular AF receiving conventional VKA but no controlled and those controlled who received VKA or DOAC. Approximately 500 patients seen in internal medicine are planned to be included in the study. Patients should be included in a ratio 2:1, 2 patients controlled (VKA patients with a Time in Therapeutic range TTR ≥ 65% and all DOAC patients) per 1 patient uncontrolled (VKA patients with a TTR < 65%), due to the controlled patients comprise more treatments. The design of the study impose an only visit to be performed that will coincide with one of those performed by the patients as part of routine follow-up of their disease, without interfering with usual clinical practice of the investigator. HRQoL will be based on the patients’ ratings on Sawicki questionnaire completed during the only study visit. This questionnaire includes 32 items grouped in 5 dimensions – treatment satisfaction, self-efficacy, strained social network, daily hassles and distress. Higher scores indicate lower HRQoL. The scores of each individual question will be summarized descriptively in thecontrolled and uncontrolled patients.
