Knowledge level and coping strategies according to coagulation levels in older persons with atrial fibrillation

The present study examined the knowledge level and the coping strategies of older persons with atrial fibrillation, who were on oral anticoagulant therapy. The relationship among knowledge level, problem and affective-oriented coping strategies, and the level of anticoagulant effectiveness were examined. We also compared differences between subjects who were within a therapeutic range for International Normalized Ratio levels with those who were not. The research design was descriptive and correlational. One hundred older persons completed the Jaloweic Coping Scale (a knowledge questionnaire) and socio-demographic, contextual and clinical characteristic questions. The findings suggested that the knowledge levels were low (53%), and problem-oriented coping strategies were most often used (32.62%) compared to affective-oriented coping strategies (18.96%). Other than praying and putting one's trust in God (P = 0.05), it appeared that no other significant coping strategies differentiated the subjects regarding their level of anticoagulant effectiveness. It is recommended that further examination of the reasons for older persons' low knowledge level, in regard to their oral anticoagulant therapy, occurs and that use of problem-oriented coping strategies, to improve self-care measures, be encouraged.
