Introduction

Adopting new teaching and learning strategies in nursing is very important for excellence in the development of students’ knowledge, skills and attitudes^(1-2). Thus, clinical simulation, configured as a pedagogical mechanism for teaching and learning in health, which imitates real clinical care, has gained space in nursing education, characterized as an experiential, interactive, collaborative and learner-centered strategy⁽³⁾.

Specifically regarding teaching and learning of cardiopulmonary resuscitation (CPR) for nursing, strategies frequently adopted by educators are still guided by traditional approaches, such as lectures supported by PowerPoint^® presentations and laboratory skills training guided by an instructor^(4-5).

This classic pattern of CPR training has shown ineffective results for care quality, such as a decrease in the cognitive and psychomotor skills of individuals 1 month after the completion of the courses^(6-7). However, it is not yet clear whether new teaching and learning strategies, such as clinical simulation, are more effective in developing the competence of nursing students to attend CPR^(4,8).

The evaluation of the development of clinical competence, defined as the application of skills in all domains of practice, articulating knowledge, skills and attitudes in different clinical contexts^(7,9), is considered a complex and difficult to handle topic. Its use in the teaching of CPR to nursing students was verified in studies whose outcomes were varied and not always conclusive regarding its effectiveness^(10-12).

This study aimed to identify the effectiveness of clinical simulation for competence development regarding CPR in comparison with different teaching and learning strategies used in the education of nursing students.

Method

This is a systematic literature review, prepared in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) strategy⁽¹³⁾, from July to October 2019.

To comply with this systematic review, seven steps were followed: (1) definition of the research question, specifying the population and the intervention of interest; (2) identification of databases, descriptors, keywords and search strategies; (3) establishment of inclusion and exclusion criteria; (4) search databases with up to two independent researchers; (5) comparison of examiners’ searches and definition of initial study selection; (6) application of the inclusion criteria and justification for possible exclusions, along with the critical analysis of all studies included in the review; (7) elaboration of a critical summary, synthesizing the information made available by the articles included in the review, and presentation of conclusion, informing the evidence on the effects of the intervention⁽¹⁴⁾.

The research question was defined through the Patient - Intervention - Comparison-Outcomes (PICO) strategy⁽¹⁵⁾ with the following elements: the acronym P referred to undergraduate nursing students; I, clinical simulation; C, different teaching and learning strategies; and O, the development of clinical competence for CPR. Thus, the following guiding question was structured: What is the effectiveness of clinical simulation in comparison with different teaching and learning strategies for competence development regarding CPR in nursing students?

The following databases were defined as data source: PubMed^®/MEDLINE^®, Latin American and Caribbean Literature on Health Sciences (LILACS), Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Web of Science.

According to the database, specific descriptors and search strategies were used. In PubMed^® and Scopus, the descriptors found in Medical Subjects Headings (MESH) “Students, Nursing”, “Simulation Training”, “Teaching”, “Clinical Competence” and “Cardiopulmonary Resuscitation” were used, and the search strategies were P versus I − (“Students, Nursing” OR “Pupil Nurses” OR “Student, Nursing” OR “Nurses, Pupil” OR “Nurse, Pupil” OR “Pupil Nurse” OR “Nursing Student” OR “Nursing Students”) AND (“Training, Simulation” OR “Interactive Learning” OR “Learning, Interactive”) - and I versus C versus O − (“Training, Simulation” OR “Interactive Learning” OR “Learning, Interactive”) AND (Teaching OR “Training Techniques” OR “Technique, Training” OR “Techniques, Training” OR “Training Technique” OR “Training Technics” OR “Technic, Training” OR “Technics, Training” OR “Training Technic” OR “Pedagogy” OR “Pedagogies” OR “Teaching Methods” OR “Method, Teaching” OR “Methods, Teaching” OR “Teaching Method” OR “Academic Training” OR “Training, Academic” OR “Training Activities” OR “Activities, Training” OR “Training Activity” OR “Techniques, Educational” OR “Technics, Educational” OR “Educational Technics” OR “Educational Technic” OR “Technic, Educational” OR “Educational Techniques” OR “Educational Technique” OR “Technique, Educational”) AND (“Clinical Competence” OR “Competency, Clinical” OR “Competence, Clinical” OR “Clinical Competency” OR “Clinical Competencies” OR “Competencies, Clinical” OR “Clinical Skill” OR “Skill, Clinical” OR “Skills, Clinical” OR “Clinical Skills”) AND (“Clinical Competence” OR “Competency, Clinical” OR “Competence, Clinical” OR “Clinical Competency” OR “Clinical Competencies” OR “Competencies, Clinical” OR “Clinical Skill” OR “Skill, Clinical” OR “Skills, Clinical” OR “Clinical Skills”) AND (“Cardiopulmonary Resuscitation” OR “Resuscitation, Cardiopulmonary” OR CPR OR “Cardio-Pulmonary Resuscitation” OR “Cardio Pulmonary Resuscitation” OR “Resuscitation, Cardio-Pulmonary” OR “Code Blue” OR “Mouth-to-Mouth Resuscitation” OR “Mouth to Mouth Resuscitation” OR “Mouth-to-Mouth Resuscitations” OR “Resuscitation, Mouth-to-Mouth” OR “Resuscitations, Mouth-to-Mouth” OR “Basic Cardiac Life Support” OR “Life Support, Basic Cardiac”).

In CINAHL, the descriptors were “Students, Nursing”, “Simulations”, “Teaching”, “Clinical Competence” and “Resuscitation, Cardiopulmonary”, identified in titles, and the following search strategies were applied: P versus I - (“Students, Nursing”) AND (Simulations) - and I versus C versus O - (Simulations) AND (Teaching OR “Models, Educational”) AND (“Clinical Competence”) AND (“Resuscitation, Cardiopulmonary”).

In Web of Science, the descriptors “Students, Nursing”, “Simulation Training”, “Teaching”, “Clinical Competence” and “Cardiopulmonary Resuscitation” were used. The search strategy was configured as: (“Students, Nursing” AND “Simulation Training” AND Teaching AND “Clinical Competence” AND “Cardiopulmonary Resuscitation”).

At LILACS, the following Health Science Descriptors (DeCS) were searched: “Nursing Students”, “Simulation Training”, “Teaching”, “Clinical Competence”, “Cardiopulmonary Resuscitation” and their English and Spanish versions, with the following search strategy: (“Students, Nursing”) AND (“Simulation Training”) AND (Teaching) AND (“Clinical Competence”) AND (“Cardiopulmonary Resuscitation”) (“Estudiantes de Enfermería”) AND (“Entrenamiento Simulado”) AND (Enseñanza) AND (“Competencia Clínica”) AND (“Reanimación Cardiopulmonar”) (“Nursing Students”) AND (“Simulation Training”) AND (Teaching) AND (“Clinical Competence”) AND (“Cardiopulmonary Resuscitation”).

Primary studies of clinical trial type, randomized or not, were included, which presented the comparison of the effectiveness of clinical simulation to develop competence on CPR in adults with other teaching and learning strategies applied to undergraduate nursing students, without delimited timeline; published in Portuguese, English and Spanish; in scientific journals and electronically available. Studies that addressed nursing professionals, neonatal and pediatric CPR, literature reviews, editorials, reviews, experience reports, case studies, theoretical reflections, dissertations, theses, monographs and summaries published in annals of events were excluded.

The studies were identified in the information sources selected by two independent researchers, previously trained to evaluate titles and abstracts, through a single version free web review program named Rayyan Qatar Computing Research Institute (Rayyan QCRI)⁽¹⁶⁾, identified at the link https://rayyan.qcri.org/.

Rayyan QCRI helps authors of systematic reviews to carry out their work quickly, easily and pleasantly, allowing the export of studies from a certain database for the program and the exposure of titles and abstracts, with the blindness of the auxiliary researcher, which guarantees reliability in the selection of information, accuracy and methodological precision⁽¹⁶⁾.

The 12 studies that showed divergence were sent to a third researcher, specialized in the theme, responsible for making the decision to include or exclude, and then a critical analysis of the articles was carried out. After we observed the incipience of selected studies, the references of the included articles were analyzed, without resulting in new additions to the final sample.

In data collection, the criteria from a validated instrument⁽¹⁷⁾ were used, addressing title, authors, year of publication, origin of the study, language, journal, objectives, methodological design, results and conclusion. The Evidence Level⁽¹⁸⁾ was also classified and the selection and inclusion of studies was demonstrated following the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analyzes-PRISMA⁽¹³⁾.

The methodological evaluation of the selected studies was carried out according to the critical evaluation instruments from Joanna Briggs Institute⁽¹⁹⁾ and Medical Education Research Study Quality Instrument (MERSQI)⁽²⁰⁾. We opted to use both to obtain a broad scenario of evaluation of the articles methodological quality, since the adopted instruments have different perspectives and evaluation criteria.

The instrument referring to Joanna Briggs Institute has a total of nine items of methodological evaluation aimed at quasi-experimental studies and 13 for experimental ones and considers whether they are present, absent, and whether there is clarity or not⁽¹⁹⁾. MERSQI consists of a total of six domains, composed of criteria that assess the methodological quality of the studies: (1) study design (only one group or a post-test, 1 point; pre-test and post-test of a single group, 1.5 points, two non-randomized groups, 2 points and a randomized study, 3 points); (2) sample (one studied institution, 0.5 point; two institutions, 1 point; three studied institutions, 1.5 point and the sample response rate <50%, 0.5 point; 50% to 74%, 1 point and >75%, 1.5 points); (3) data type (assessment made by the participants, 1 point and objective assessment, 2 points); (4) validity of the assessment instrument (internal structure not reported, zero point; reported, 1 point; unreported content, zero point; reported content, 1 point; relations with other unreported variables, zero point and reported relations, 1 point); (5) data analysis (inappropriate for the study design or data type, zero point; appropriate for the study design, 1 point; only descriptive analysis, 1 point; in addition to descriptive analysis, 2 points); and (6) results (obtaining knowledge and skills, 1.5 points; satisfaction, attitudes, perceptions, opinions, general facts and confidence, 1 point). The maximum score is 18⁽²⁰⁾. Studies with scores ≤10 are considered low quality ones; from >10 to <15, moderate quality; and ≥15, high quality⁽²¹⁾.

• ^*
  RCT = Randomized clinical trial

The quasi-experimental studies included in this review met most of the quality assessment requirements indicated by the instrument of Joanna Briggs Institute, being considered of good quality. Only the criterion that addresses the use of multiple measurements of results in pre- and post-intervention/exposure over time has not been met in two studies^(23-24).

As for experimental studies, despite the fact that most criteria indicated for quality assessment have been met, there was a significant methodological weakness regarding the blinding of the researcher, participants, those responsible for providing treatment and results evaluators regarding the allocation of treatment.

MERSQI was also used to assess the methodological quality of the studies included in the sample, shown in Figure 4.

Through the use of MERSQI, it is possible to state that the studies included in the sample of this review had moderate methodological quality (10< n <15), with an average score of 12.5 points, a minimum value of 11 and a maximum value of 14.5 points. The criteria responsible for conferring methodological weakness were the execution of the studies in a single center/institution and the lack of clarification as to the validity of the assessment instruments highlighted by these manuscripts.

The articles included in the review are summarized in Figure 5. All of them were international publications. The authors identified that clinical simulation was an effective teaching and learning strategy to develop clinical competence in nursing students for cardiopulmonary resuscitation, when compared to other teaching mechanisms.

  CPR = Cardiopulmonary resuscitation

Discussion

A total of three quasi-experimental studies^(22-24) and two experimental^(25-26) were included in the sample of this review. Although all authors have pointed to clinical simulation as an effective strategy to develop clinical competence for cardiopulmonary resuscitation in nursing students, the scarcity of identified studies demonstrates the need for further scientific exploration in this area⁽⁹⁾.

Most^{(22-23,25-26)} studies have compared clinical simulation in CPR with traditional teaching and learning strategies for nursing, such as lecture with the support of PowerPoint presentations and the training of laboratory skills using a low fidelity manikin. They obtained statistically significant results for clinical simulation in CPR in view of other exposed methods, which can subsidize their use in nursing education^(9,22-23).

A randomized experimental study carried out with a total of 31 Chinese nurses, that compared the effectiveness of simulation to develop nursing competence with traditional teaching strategies corroborates this statements, highlighting statistically significant results for the increase of cognitive and psychomotor skills (p=0.001), a reduction in stress levels (p=0.011) and increased confidence (p=0.026)⁽²⁷⁾.

Other studies have also pointed out clinical simulation as an innovative pedagogical strategy for the development of cognitive, psychomotor and affective skills in nursing, affirming its effectiveness for the development of clinical competence^(25,28-30).

This review used two different instruments^(19-20) to assess the methodological quality of the selected article sample. Joanna Briggs Institute instrument pointed out the good quality of quasi-experimental and experimental studies, but it highlighted the blinding criterion as an important methodological weakness in experimental studies.

The absence of the participant, personnel or statistician blinding, in a scientific study, can compromise the methodological quality by providing biased behavior of those involved and research bias, which affects the internal validity of the investigations and makes the effectiveness of the research uncertain. However, it is worth noting the existing difficulty to perform blinding in educational experiments, mainly due to the impossibility of guaranteeing the absence of exchange of information among the participants involved^(19,31-36).

MERSQI, another instrument used in this study, is described as reliable because it provides accuracy in identifying the methodological quality of the articles⁽³⁷⁾. This assessment instrument identified a moderate level of quality in the researches that comprised the sample, highlighting as main weaknesses the execution of studies in a single center/institution and the lack of clarification of the validity of the instruments used.

This result is similar to a systematic review study on education based on simulation in nursing, which also used MERSQI and indicated moderate methodological quality for a sample of a total of 26 articles, in addition to the need for improvement in the preparation of educational intervention studies in nursing, mainly because they are performed in a single center and do not consider the previous validation of the instruments used⁽³⁷⁾.

Despite the fact that multicenter clinical trials are considered the gold standard in research, since they attend different communities and reduce the time of experimentation, they are generally expensive and complex studies, which makes its execution difficult and can justify the fact that most scientific publications on pedagogical interventions in nursing be carried out in a single center⁽³⁸⁾.

On the other hand, the validation of instruments is a criterion of fundamental methodological quality, as it confers the reliability of the intended findings. The lack of clarification on this issue, in the studies that comprised the sample of this review, may compromise the reliability of the statistical conclusions of researches and justify its moderate methodological quality⁽³⁹⁾.

This study had two main limitations: the incipience of quasi-experimental and experimental articles on the effectiveness of simulation to develop clinical competence in CPR; and the difficulty to compare the results of the studies that made up the sample, in view of the approach to different evaluation instruments.

Based on the findings of this systematic review, it is possible to add scientific evidence capable of supporting the teaching and learning process of CPR in undergraduate nursing through clinical simulation, indicating its effectiveness, focusing on the methodological quality of studies, which is an important resource in view of the accelerated growth of information.

Conclusion

We identified a total of five studies that confirm the effectiveness of clinical simulation to develop competence in cardiopulmonary resuscitation for nursing, in view of other pedagogical strategies. Joanna Briggs Institute methodological assessment instrument demonstrated good quality of the included studies, and the Medical Education Research Study Quality Instrument showed moderate methodological quality.

This study contributes to teaching, research and nursing care, as it demonstrates the effectiveness of simulation as a teaching and learning strategy, indicating it as a pedagogical possibility to develop clinical competence in cardiopulmonary resuscitation.
