Factors leading to poor adherence to secondary prophylaxis of rheumatic fever

Abstract

Objectives: The objective of this study was to determine the level of adherence and possible barriers to secondary prophylaxis among patients with Rheumatic heart disease (RHD). Methodology: It is a cross-sectional study conducted at the largest tertiary care cardiac center of Karachi, Pakistan. We included patients with RHD, based on transthoracic echocardiography and adherence to the secondary prophylaxis and possible barriers were assessed using a structured questionnaire. Results: Among total of 195 patients 66.7% (130) were female, mean age was 32.25 ± 13.78 years. Rural residents were 51.3% (100) and 59.5% (116) of the patients were illiterate. Benzathine Penicillin injection was prescribed to 56.4% (110) patients, out of them 70.0% (77) of the patients were counseled regarding duration of secondary prophylaxis. The most common reason for non-adherence was reported to be a painful injection (19.1%). Conclusion: Majority of the RHD patients are not being prescribed and effectively counseled regarding secondary prophylaxis. Low adherence to the secondary prophylaxis was observed and the common reasons for non-adherence were painful injection, non-availability of nearby health facility, friends/family advising them otherwise, allergic reaction, and patients feeling sick and unable to take injection.
