Treatment satisfaction and medication adherence attitudes among hypertensive patients: a cross-sectional study in a low-to-middle-income country
摘要
One major barrier to effectively managing blood pressure in hypertensive patients is nonadherence to antihypertensive drugs. Therefore, the primary goal of the current study was to assess hypertensives’ attitudes toward the use of antihypertensive drugs.
MethodsThis cross-sectional study’s methodological instrument was a questionnaire. The locations used for the study were the primary healthcare facilities under the Ministry of Health. In addition to clinical and demographic information, the questionnaire included the Arabic versions of the Drug Attitude Inventory (DAI-10) and the Treatment Satisfaction Questionnaire for Medication (TSQM).
ResultsIn this study, 356 patients with hypertension were included. More than half of the patients (57.6%, n = 205) were on amlodipine, whereas 117 (32.9%) used valsartan. The vast majority of the patients (95.2%) believed that they benefited from their antihypertensive drugs, with the benefits outweighing the drawbacks. The majority were satisfied with the effectiveness of their antihypertensive medications, 59.6% were very satisfied, and 23.3% were satisfied with the ability of antihypertensive medications to treat the disease condition. The DAI-10 score was negatively associated with the time since diagnosis (p = 0.004), the presence of documented food or drug allergies (p < 0.001), and the body mass index (BMI) (p = 0.004). In contrast, DAI-10 scores were positively associated with the perceived effectiveness of antihypertensive medications (p = 0.010), convenience (p = 0.040), and global satisfaction scores (p < 0.001). The perceived effectiveness score was significantly associated with side effect scores (p = 0.002), convenience (p < 0.001), and global satisfaction (p < 0.001). Global satisfaction was negatively associated with time since diagnosis (p = 0.008) and positively associated with the DAI-10 score (p < 0.001), effectiveness (p < 0.001), and side effects (p < 0.001).
ConclusionsThis study revealed that attitudes toward and levels of satisfaction with antihypertensives were positive and high among hypertensive patients. This is specifically related to the effectiveness and convenience of antihypertensives. The time since the diagnosis of hypertension, records of documented allergies, and patient BMI play significant roles as predictive factors for the development of negative attitudes and lack of patient satisfaction. Measures should therefore be put in place to encourage positive attitudes and satisfaction among hypertensive individuals.
