Aim:

To evaluate and compare treatment compliance among different oral anticoagulants.

Design:

Transversal descriptive study.

Location:

Primary Care. Bargas Basic Healthcare Area.

Participants:

Patients in treatment with oral anticoagulants more than 6 months who belonged to six Family Medicine quotas were included. Displaced patients, those unable to take medication autonomously, admitted to hospital or who died during the study were excluded.

Primary endpoints:

The variables studied were: age, sex, educational level, family unit, treatment time, type of anticoagulant, side effects, polymedication, type of prescription, education for health and treatment compliance. Descriptive statistics and analysis were performed.

Results:

110 patients with a mean age of 73.02 (SD: 12.06) years old were studied. A total of 29.1% were in treatment with oral anticoagulants (OACs). Median treatment time was 47 months (interquartile range: 16-77.25). A total of 84.5% were polymedicated (7.36±3.96 drugs on average). In total 81.81% (95%CI 73.32-88.52%) were compliant. A total of 93.75% complied with OACs (95%CI 79.19-99.23%) compared to 76.92% with acenocumarol (95%CI 66.00-85.71%) (p=0.055). Compliance in polymedicated patients was 86% compared to 58.8% in non-polymedicated patients (p=0.02).

Conclusion:

Our study revealed an apparent greater treatment adherence in patients treated with OACs in regard to those treated with acenocumarol. Treatment adherence is greater in polymedicated patients.
