Critical Appraisal Quantitative Articles

Critical Appraisal Quantitative Articles


The study focuses on workplace violence against nurses and explores the approaches of addressing the issue in the contemporary clinical setting. The PICOt statement states ‘For emergency nurses and staff (ED) (P) Does the use of Interventions and Response training Courses (I) help in recognizing and mitigating all workplace violence (O) compared to the existing no-training approach (C)?’ The appraisal examines Hemati –Ismaeili et al.’s (2018) which sought to explore policy measures meant to reduce WPV against nurses in the ED using educational and managerial interventions. The next article by Shi et al (2017) purposed to assess the prevalence and related risk factors of WPV against Chinese nurses.

Hemati- Ismaeli et al.’s (2018) study is informed by the need to address the increasing research of workplace violence, which according to the findings, has increased by almost 30% to rise from 68. % to 98.8% across various healthcare settings, of which the ED is a part. The article’s significance in nursing is that its implementation is bound to create a safer environment not just for patient care but also lead to a reduction in WPV unleashed on nurses by either the patient or their families within the ED. The purpose and overarching objective were to plan a WVP prevention program.

On the other hand, Shi et al. (2017) conducted a cross-sectional study on WPV were just like their counterparts in this paper found that in China, WPV had risen to 96% up from 90%. The purpose and primary objective of the study was to explore the features of WPV encountered by nurses in China at tertiary and county-level hospitals. The study sought to conduct identification and analysis of risk factors for WPV and then develop the grounds for its future preventive strategies.

How do these two articles support the nurse practice issue you chose?

The two articles will be useful in answering the pertinent issue of WPV directed against nurses working in the ED because by establishing the risk factors associated with Chinese nurses as indicated by Shi et al. (2017) one could use these as the basis for advancing an evidence-based intervention. The prevalence rates would be useful as the baseline to assess and evaluate the success of the PICOT Question-based intervention. Similarly, Hemati- Ismaeili et al. (2018) findings would play a significant part in the formulation and implementation of the EBP project since it delves into the efficacy of some of the educational and managerial policy interventions which have been proposed and their success in decreasing WVP against nurses stationed at the ED. The two are relevant in answering my research question of using an education intervention to reduce WVP.

Method of Study:

Shi et al. (2017) used the cross-sectional study as their research methodology which involved the use of stratified random sampling to collect data spanning two years from Dec 2014 to Jan 2016. This contrasts with the Iranian scholars Hemati-Ismaeli and others used a combination of both quantitative as well as qualitative. Since in my proposed research, I have opted for qualitative methodology as the approach to use in my research project, one of its benefits is that it produces an in-depth description of the participants’ experiences, there and opinions which helps a lot during the interpretation of their actions. However, on the flip side, the use of a qualitative approach in research has the limitation of glossing over contextual sensitivities, which may lead to undue attention being focused more on meanings and experiences.

Shi et al. (2017)  use of cross sectional study, as quoted in this paper has the advantage of not being demanding in terms of financial costs and time needed to research from beginning to end. Its main disadvantage is that since it only captures data at a specific point in time, it cannot be used for behavior analysis over a long period. Lastly, Hemati- Ismaeli and company research, which used a mixed-method approach, has the merit of having the combined strengths of both quantitative and qualitative studies. For example, researchers using this method can use numbers to add specificity to words, pictures or even narratives. However, critics of the mixed-method approach point out that one of its demerits is that it leads to much duplicity of content making it difficult for one researcher to use this method.

Results of Study

Shi et al. (2017) results indicated that the prevalence of WPV stood at 66%, of which 65% was verbal violence. With verbal violence taking the top slot, physical violence was ranked second at 12% while sexual harassment stood at 4%. After going through Hemati- Ismaeili’ et al. (2018) findings, their results indicated that before the implantation of WVPP, verbal violence stood at 5.7% but decreased to 57.1 % once the program was proposed. The implications of these findings to nursing are due to its widespread nature and cutting across all healthcare settings. It is the responsibility of all stakeholders to develop and ensure that effective control strategies of VWP are put in place from the individual to the hospital up to the national levels.

Outcomes Comparison

The anticipated outcomes of my PICOT Question-based EBP project which entails the use of interventions and training courses, will improve the identification and mitigation of all forms of WPV. This will be evidenced by a decrease in the fall of incidence rates in terms of percentages and also help in mitigating the adverse effects WPV has on the performance, health and works satisfaction among ED nurses. These outcomes compare to those of the two articles herein critically analyzed in that it uses an educational intervention approach that has been demonstrated to be effective.


In conclusion, this paper has established that critical appraisal of published research findings is important not just for scholarly purposes but also for healthcare professionals actively working in clinical practice. This is because the integration of proposed changes into patient-centered care guidelines and recommendations calls for a thorough analysis of current literature for the success of evidence-based nursing care and therapeutic interventions.
