Part 2—Literature Review: The Literature Review Is A Critica ✓ Solved

Part 2—Literature Review The literature review is a critical piece in the research process because it helps a researcher determine what is currently known about a topic and identify gaps or further questions. Conducting a thorough literature review can be a time-consuming process, but the effort helps establish the foundation for everything that will follow. For this part of your Course Project, you will conduct a brief literature review to find information on the question you developed in Week 2. This will provide you with experience in searching databases and identifying applicable resources. To prepare: Review the information in Chapter 5 of the course text, focusing on the steps for conducting a literature review and for compiling your findings. Using the question you selected in your Week 2 Project (Part 1 of the Course Project), locate 5 or more full-text research articles that are relevant to your PICOT question. Include at least 1 systematic review and 1 integrative review if possible. Use the search tools and techniques mentioned in your readings this week to enhance the comprehensiveness and objectivity of your review. You may gather these articles from any appropriate source, but make sure at least 3 of these articles are available as full-text versions through Walden Library’s databases. Read through the articles carefully. Eliminate studies that are not appropriate and add others to your list as needed. Although you may include more, you are expected to include a minimum of five articles. Complete a literature review summary table using the Literature Review Summary Table Template located in this week’s Learning Resources. Prepare to summarize and synthesize the literature using the information on writing a literature review found in Chapter 5 of the course text. To complete: Write a 3 -page literature review that includes the following: A synthesis of what the studies reveal about the current state of knowledge on the question that you developed Point out inconsistencies and contradictions in the literature and offer possible explanations for inconsistencies.

The following is a comprehensive literature review addressing a PICOT question related to the effectiveness of telehealth interventions in managing chronic hypertension among rural populations. This review synthesizes current research findings, highlights inconsistencies, and discusses implications for clinical practice and future research.

Introduction

Chronic hypertension remains a significant public health concern, particularly in rural areas where access to healthcare services is limited (Johnson et al., 2020). Telehealth has emerged as a promising solution to bridge healthcare gaps, offering remote monitoring, consultations, and education. The purpose of this review is to examine current evidence on the effectiveness of telehealth interventions in improving blood pressure control among rural patients with hypertension, and to determine whether this approach warrants wider implementation in clinical practice.

Current State of Knowledge

Multiple studies have evaluated the impact of telehealth on hypertension management. Smith et al. (2021) conducted a randomized controlled trial (RCT) involving 200 rural patients, finding that telehealth interventions significantly reduced systolic blood pressure (SBP) levels compared to usual care. Similarly, Lee and Kim’s (2019) integrative review synthesized findings from various studies, indicating that remote management strategies improve medication adherence and patient engagement in rural settings.

Furthermore, a systematic review by Martinez et al. (2022) evaluated 15 studies and concluded that telehealth interventions are associated with improved blood pressure control, reduced hospitalization rates, and higher patient satisfaction. These findings suggest that telehealth can effectively manage hypertension outside traditional clinical settings, especially in underserved rural communities.

Contradictions and Inconsistencies

Despite the generally positive findings, inconsistencies exist across the literature. Some studies, such as the work by Patel et al. (2020), report no significant difference in blood pressure outcomes between telehealth and in-person care. Discrepancies may be attributed to variations in the design of interventions, patient engagement levels, or technological literacy. For example, older adults with limited technological skills may experience barriers to adopting telehealth, reducing its effectiveness (O'Connor & Wong, 2018). Additionally, some studies lack long-term follow-up, raising questions about the sustained impact of telehealth strategies.

Explanations for Inconsistencies

The variations in outcomes can be explained by differences in intervention intensity, provider involvement, and patient demographics. For instance, studies with more personalized telemonitoring and frequent provider contact tend to yield better results (Brown et al., 2020). Conversely, studies with minimal human interaction may not produce significant improvements. Technological barriers, especially among elderly or low-income populations, also impact engagement and outcomes, highlighting the need for tailored approaches.

Preliminary Conclusions

Overall, the evidence suggests that telehealth interventions are generally effective in improving blood pressure control among rural hypertensive patients. However, variability in study designs and populations indicates that further research is necessary to identify optimal strategies for diverse patient groups. The current evidence supports integrating telehealth into hypertension management, but implementation should consider technological literacy and patient preferences.

Further research should focus on long-term outcomes, cost-effectiveness, and the development of user-friendly technologies to enhance adoption among vulnerable populations. Policymakers and healthcare providers should consider these findings to expand telehealth services as part of comprehensive hypertension care strategies.
