Summary
The article focuses on the cardiovascular disease (CVD) impacts that cause a high death rate and pose a global public health problem. Even though CVD is now more manageable, Zhang and Fa (2021) report that patients continue to struggle with medication adherence and lifestyle adjustments. As a result, the study aimed to conduct a meta-analysis of prior studies to establish the effect of nursing intervention (NI) on managing blood pressure and tolerance to lifestyle changes.
Characteristics of the Meta-Analysis
A meta-analysis is a statistical method used to combine and examine data from unrelated studies on a specific subject, thereby integrating the results. The work by Zhang and Fa (2021) possesses several qualities that qualify it as a meta-analysis. The pooling of data is the first evident component, as Zhang and Fa (2021) combine data from several studies.
According to Haidich (2010), the objective is to improve the statistical power and accuracy of their conclusions. Out of the 905 papers found in the various databases, eight articles were selected for review (Zhang & Fa, 2021). The criteria for inclusion or omission of studies are clearly defined to assure relevance and comparability (Siddaway et al., 2019), comprising four and three parameters, respectively. Zhang and Fa (2021) conducted a statistical quantitative analysis of the data, where the I2 statistic was used to determine the degree of heterogeneity. However, the I2 is characterized by a high bias, especially considering the small number of studies that were reviewed.
Furthermore, the article includes a forest map and a sensitivity analysis to illustrate concentration and the parameters that significantly affect the model’s stability. Confidence intervals were used to establish a range of values within which the true effect size was anticipated to fall (Seidler et al., 2020). The researchers also assessed the risk of bias in the chosen papers and found that while two publications had some risk of bias, the other six studies had none. They also conducted a statistical significance test to ascertain whether the total effect size was statistically significant. For instance, the fasting blood glucose levels of the NI and RC groups differed significantly (Zhang & Fa, 2021). The authors provided additional interpretation of the findings by providing insights and conclusions based on the pooled data from all included studies.
Inclusion and Exclusion Criteria
The researchers clearly described the inclusion and exclusion criteria used to select the publications for the study. A further four criteria were used to select the qualifying articles for Zhang and Fa’s study (2021), which was based on articles using the randomized controlled trials methodology. These criteria were: A comparison of nursing intervention (NI) versus routine nursing care (RC); Patients receiving treatment for cardiovascular disease (CVD); The efficacy of treatment for patients with CVD; Articles where the full text was provided. I concur with the researchers’ strategy given that the parameters were clearly defined, including the interventions, population of study, efficacy of treatment, and the availability of the articles in full text.
Verdict on the Conclusions
I agree with how the findings have been contextualized to support the finding that most CVD patients can be safely treated with NI. Zhang & Fa (2021) provide an alternative interpretation and demonstrate a connection with other findings and the broader scientific context, such as Hendriks et al.’s (2014) work, as cited in Zhang & Fa (2021). The discussion outlines the limitations and implications for future clinical research and shows how the results align with the objectives stated in the introduction. The findings offer new understandings and contributions to clinical practice.
Applying the Implications to Nursing Practice
The critical nursing objectives for patients with CVDs include encouraging physical activity, reducing fatigue, alleviating symptoms of fluid overload, managing anxiety, promoting patient empowerment in decision-making, and providing the patient and their family with health education. I would refer to the implications of the article by applying NI over RCs to help manage patients with CVDs and achieve the outlined nursing objectives. This is crucial since it can help prevent the disease’s progression and reduce the risk of complications.
