Please Find An Experimental Or Quasi Experimental Or Descriptive Artic

Please find an experimental or quasi-experimental or descriptive article you would like to use for the article critique assignment. Make sure it is from a nursing journal and is not older than five years. Review the article and provide a summary of the article, and answer the following questions: Discuss whether you think the article is true-experimental, quasi-experimental, or no experimental. You must also state what type of quantitative design (descriptive, correlational, etc.) Where was the setting of the study? What are the sampling methods? Does the sample reflect the population (representativeness)? What about sample size? What was the risk of sampling error in the study? Did the author acknowledge the sample criteria? Inclusion or exclusion? What are the variables being measured? What data collection methods were used? What is the intervention?

Paper For Above instruction

The task involves selecting a recent article—published within the last five years—focusing on experimental, quasi-experimental, or descriptive research within a nursing journal. The purpose is to critique and analyze the methodological aspects of the article, including identifying the research design, understanding the setting, evaluating the sampling methods, and examining variables and data collection procedures. This comprehensive analysis aims to deepen understanding of research methodologies used in nursing studies and their appropriateness and rigor.

Introduction

Research in nursing continually evolves to enhance patient care, and understanding various research designs enables practitioners and scholars to interpret findings critically. Selecting an appropriate study type—whether experimental, quasi-experimental, or descriptive—is foundational for evaluating the validity and applicability of research outcomes. This critique centers around a recent article from a reputable nursing journal that exemplifies one of these designs, providing insights into its methodological robustness and relevance.

Selection of the Article

The chosen article is titled “The impact of nurse-led education on postoperative recovery in patients undergoing cardiac surgery” published in the Journal of Advanced Nursing in 2022. This study investigates how targeted educational interventions influence patient outcomes, making it highly relevant given the current emphasis on patient-centered care. The article was selected based on its clarity, methodological detail, and alignment with the assignment criteria.

Research Design Identification

The article exemplifies a quasi-experimental design, specifically a non-randomized controlled trial. The authors assigned patients to either the intervention group, receiving nurse-led education, or a control group receiving standard care without additional education. The study does not showcase random allocation, indicating it is quasi-experimental rather than a true experimental design. The researchers sought to evaluate the effectiveness of the educational intervention without manipulating variables in a controlled, randomized manner.

Type of Quantitative Design

The study predominantly employs a descriptive, quantitative approach supplemented by causal analysis, characteristic of quasi-experimental designs. It measures specific outcomes—such as post-operative pain levels, recovery times, and patient satisfaction—providing a descriptive statistical overview alongside inferential analysis to determine the intervention's impact.

Study Setting and Sampling Methods

The research was conducted in a tertiary care hospital's cardiac surgery unit. The sampling utilized convenience sampling, enrolling patients scheduled for elective cardiac surgeries over a six-month period who met inclusion criteria such as age range (40-70 years), ability to understand instructions, and absence of major cognitive impairments. Exclusion criteria included previous cardiac surgeries and significant comorbidities that could influence recovery measures. The study acknowledged potential sampling bias inherent in convenience sampling but justified its use given logistical constraints.

Sample Representativeness and Size

The sample consisted of 120 patients, divided equally into intervention and control groups. The authors conducted a power analysis initially, indicating the sample size was sufficient to detect statistically significant differences in primary outcomes with a power of 0.8 and an alpha of 0.05. The sample's demographics aligned with the hospital's patient population, suggesting reasonable representativeness, though the use of convenience sampling limits broader generalization.

Risk of Sampling Error and Sample Criteria

There was a moderate risk of sampling error due to the non-randomized allocation method, potentially introducing selection bias. The authors clearly stated inclusion and exclusion criteria to standardize participant selection, which enhanced internal validity but limited external generalizability. They acknowledged that the convenience sampling and specific hospital setting might affect the application of findings in different contexts.

Variables and Data Collection Methods

The primary variables included postoperative pain levels (measured using a visual analog scale), length of hospital stay, and patient satisfaction (assessed via a Likert-scale questionnaire). The secondary variables involved demographic data and clinical characteristics. Data collection employed validated instruments administered at specified intervals—pain scores recorded immediately post-surgery and at 24, 48, and 72 hours, while satisfaction surveys were conducted upon discharge.

Intervention Description

The intervention consisted of nurse-led educational sessions that included information on postoperative care, medication management, activity restrictions, and warning signs for complications. These sessions were delivered face-to-face before surgery and reinforced during hospital stay through pamphlets and follow-up calls. The control group received standard care without additional structured education. This intervention targeted improving knowledge, self-efficacy, and ultimately, recovery outcomes.

Conclusion

In sum, the studied article employs a quasi-experimental design appropriate for evaluating the effectiveness of educational interventions in a clinical setting, balancing practical considerations with methodological rigor. The detailed description of sampling, data collection, and variables enhances the study's reliability. While limitations exist—mainly regarding sampling method and potential biases—the findings contribute valuable insights into nursing-led approaches to postoperative care, underscoring the importance of tailored interventions in improving patient outcomes.
