KNOWLEDGE AND PERCEPTION OF HYPERTENSION AND ITS MANAGEMENT AMONG PATIENTS

Abstract

This study investigated patients' knowledge, perceptions, and attitudes towards hypertension and its management. A quantitative survey research design was adopted to explore these aspects comprehensively. A structured questionnaire was meticulously designed to gather data from a sample of 120 respondents. The data collected were analyzed using frequency tables, simple percentages, means, and standard deviations to provide a detailed statistical overview. Additionally, a t-test was employed to test the hypotheses stated in the study, evaluating the relationships between various factors affecting patients' understanding and management of hypertension. The findings revealed significant insights into patients' awareness and attitudes. The majority of respondents demonstrated a good understanding of hypertension and its risk factors, with 78.7% agreeing to be well-informed about the condition. However, there was variability in perceptions of how hypertension impacted daily life, with 75% of participants acknowledging significant effects, while 11.1% disagreed. The attitudes towards management strategies were largely positive, with 76% agreeing on the importance of adhering to prescribed treatment plans. The t-test results showed that patients' knowledge about hypertension and its risk factors was significantly above the assumed mean of 0, with a mean difference of 85.75 (t = 32.267, p < 0.05). Similarly, patients' perceptions of the impact of hypertension on daily life and attitudes towards management strategies were significantly higher than the assumed mean, indicating a strong awareness and positive attitude towards managing their condition. The study concluded that there is a significant level of awareness and positive attitude among patients regarding hypertension, but there are areas where perceptions and management strategies can be improved. Based on the findings, several recommendations were proposed. Firstly, healthcare providers should enhance educational programs to address gaps in understanding and reinforce the importance of managing hypertension. Secondly, integrating regular, personalized counselling sessions could improve patients' adherence to management plans. Thirdly, there is a need for targeted interventions to address specific misconceptions or barriers that might affect patients’ perceptions and daily management of hypertension. Furthermore, policymakers should support initiatives that facilitate better access to resources for hypertension management, ensuring that patients have the necessary support to adhere to treatment. Lastly, further research is recommended to explore these aspects in diverse populations and settings to develop more generalized and applicable strategies for hypertension management.

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Hypertension, commonly known as high blood pressure, is a significant public health concern globally, affecting millions of individuals regardless of age, gender, or socioeconomic status. It is a chronic medical condition characterized by elevated blood pressure levels persistently exceeding the normal range. According to Mills et al. (2020), global disparities in hypertension prevalence and control have been observed, highlighting the widespread impact of this condition across different populations and regions.

Despite its prevalence and potential complications, such as heart disease, stroke, and kidney failure, hypertension often goes undiagnosed or undertreated. Mirzaei et al. (2020) emphasized the importance of awareness, treatment, and control of hypertension among the adult Iranian population, indicating gaps in knowledge and management of this condition. This lack of awareness and inadequate management contribute to the burden of hypertension-related morbidity and mortality worldwide.

Understanding patients' knowledge and perception of hypertension and its management is crucial for effective prevention and control strategies. Guimarães et al. (2016) highlighted the role of illness perceptions in medication adherence among hypertensive patients, suggesting that individuals' beliefs and understanding of their condition influence their treatment behaviours. Similarly, Ross et al. (2020) emphasized the importance of considering patients' treatment beliefs in addressing medication noncompliance and improving hypertension management outcomes.

Health organizations like the World Health Organization (WHO) recognize the significance of adherence to long-term therapies in managing chronic conditions like hypertension (WHO, 2021). Adherence to antihypertensive medications is crucial for achieving blood pressure control and reducing the risk of cardiovascular events. Morisky et al. (2018) discussed the predictive validity of a medication adherence measure in an outpatient setting, highlighting its importance in identifying patients at risk of nonadherence and poor treatment outcomes.

The level of illness perception among hypertensive patients can influence their adherence to medical regimens. Doust Mohammadi et al. (2018) investigated the relationship between illness perception and adherence to the medical regimen in elderly patients with hypertension, suggesting that perceptions of the condition impact treatment adherence behaviours. Similarly, Taheri-Kharameh et al. (2017) assessed illness perception and adherence to therapeutic regimens among patients with hypertension, emphasizing the need to address patients' perceptions of hypertension management strategies.

Noncompliance with antihypertensive medication remains a challenge in hypertension management. Rashid et al. (2023) studied noncompliance to antihypertensive medication among patients with essential hypertension, highlighting the need for interventions to improve medication adherence and control blood pressure levels. Strategies aimed at addressing barriers to adherence, such as medication side effects or forgetfulness, are essential for improving treatment outcomes.

In addition to medication adherence, the quality of hypertension management at the community level is influenced by patients' perceptions and beliefs about their condition. Tan et al. (2017) explored hypertensive patients' perceptions towards quality use of medication and hypertension management, emphasizing the importance of patient-centered approaches in healthcare delivery. Understanding patients' perspectives can help healthcare providers tailor interventions to meet individual needs and preferences.

1.2 Statement of Problem

The management of hypertension presents significant challenges globally, despite its well-documented prevalence and associated health risks. Research indicates that awareness, treatment, and control of hypertension remain suboptimal in many populations, including in Iran (Mirzaei et al., 2020). Despite efforts to improve hypertension management, there are persistent gaps in knowledge and perception among patients, which contribute to poor adherence to treatment regimens and suboptimal blood pressure control (Guimarães et al., 2016). This lack of understanding and engagement with hypertension management leads to a significant burden of morbidity and mortality worldwide.

One critical gap in the literature is the limited understanding of illness perceptions among hypertensive patients and their impact on medication adherence (Doust Mohammadi et al., 2018). While studies have highlighted the influence of patients' beliefs and perceptions on treatment adherence, there is a need for further investigation into the specific factors shaping illness perceptions in hypertension management (Taheri-Kharameh et al., 2017). Additionally, research focusing on the determinants of noncompliance to antihypertensive medication is essential to develop targeted interventions that address the underlying reasons for treatment nonadherence (Rashid et al., 2023).

Furthermore, there is a lack of comprehensive strategies aimed at improving hypertension management at the community level, taking into account patients' perspectives and preferences (Tan et al., 2017). While patient-centred approaches have been advocated for in healthcare delivery, there is a paucity of research exploring the implementation and effectiveness of such strategies in hypertension management (World Health Organization, 2021). Addressing these gaps in the literature is crucial for developing tailored interventions that promote patient engagement, improve treatment adherence, and ultimately, enhance the effectiveness of hypertension management strategies.
