Low adherence is an essential element responsible for impaired effectiveness and efficiency in the pharmacological treatment of hypertension. Patient satisfaction is an important measure of healthcare quality and is a crucial determinant of patients' perspective on behavioural intention.
This study determined the association between medication adherence and treatment satisfaction among hypertensive patients attending hypertension outpatient clinic in Lagos University Teaching Hospital (LUTH), Nigeria.
Setting - The study setting was LUTH; a descriptive cross-sectional study was conducted. Study design - Hypertensive patients were consecutively recruited from the outpatient clinic. Medication adherence was assessed using the 8-item Morisky Medication Adherence Scale and treatment satisfaction was assessed using the 14-item Treatment Satisfaction Questionnaire for Medication.
Univariate and linear regression analyses were conducted using STATA software version 14.1 (StataCorp LP, College Station, TX, USA). Statistical significance was set at P ≤ 0.05.
A total of 500 respondents with a mean age of 58.9 ± 13.3 years participated in the study. Overall, majority (446 [89.2%]) of the respondents in this study had 'moderate' adherence to antihypertensive medication. However, only five (1.0%) respondents reported 'high' adherence. Mean scores were highest in the moderate adherence category for all satisfaction domains and overall domain. Treatment satisfaction was associated with medication adherence, and was statistically significant (P = 0.000).
One in every hundred patients had high adherence to hypertensive medication in this study, and there was a positive association between treatment satisfaction and medication adherence. Continuous patient-specific and tailored adherence education and counselling for hypertensive patients is recommended.
依从性低是导致高血压药物治疗效果和效率受损的一个重要因素。患者满意度是医疗质量的一项重要指标，也是患者行为意向观点的关键决定因素。
本研究确定了在尼日利亚拉各斯大学教学医院（LUTH）高血压门诊就诊的高血压患者中，药物依从性与治疗满意度之间的关联。
研究地点——研究地点为LUTH；开展了一项描述性横断面研究。研究设计——从门诊连续招募高血压患者。使用8项Morisky药物依从性量表评估药物依从性，使用14项药物治疗满意度调查问卷评估治疗满意度。
使用STATA软件版本14.1（美国德克萨斯州大学站StataCorp LP公司）进行单变量和线性回归分析。统计学显著性设定为P≤0.05。
共有500名平均年龄为58.9±13.3岁的受访者参与了本研究。总体而言，本研究中的大多数受访者（446名[89.2%]）对降压药物的依从性为“中等”。然而，只有5名（1.0%）受访者报告“高度”依从。在所有满意度领域和总体领域中，中等依从性类别中的平均得分最高。治疗满意度与药物依从性相关，且具有统计学显著性（P = 0.000）。
在本研究中，每百名患者中有一名对高血压药物有高度依从性，治疗满意度与药物依从性之间存在正相关。建议对高血压患者持续进行针对个体的、量身定制的依从性教育和咨询。
