Improving Nurses’ Knowledge of Continuous ST-Segment Monitoring

Standard practices in cardiac monitoring: training needs of intensive care unit nurses

BACKGROUND

Enforcing practice standards for cardiac monitoring in intensive care units (ICUs) has been shown to reduce misdiagnoses and inappropriate interventions. Continuous professional development (CPD) programs are committed to aligning clinical practices with recommended standards. The crucial initial phase in CPD development involves assessing the training needs of the targeted population.

OBJECTIVE

To assess the training needs of ICU nurses in cardiac monitoring. The overarching goal was to formulate a focused Continuous Professional Development (CPD) program geared towards implementing standard practices in cardiac monitoring.

METHODS

This study employed a generic qualitative approach with a descriptive design, utilizing interviews and focus groups from July to September 2018. Involving 16 ICU nurses. Content analysis was employed, encompassing transcription, fluctuant and iterative reading, unitization, categorization, coding, description, and interpretation.

RESULTS

All nurses recognized cardiac monitoring's importance in the ICU but reported barriers to its effective implementation which were related to factors that could addressed by a CPD as insufficient knowledge and skills. Training needs were identified in both clinical and technical aspects, with recommendations for practical and theoretical activities and e-learning strategies. Barriers related to organizational aspects (equipment and communication within the healthcare team) were also mentioned.

CONCLUSION

ICU nurses presented clear and specific training needs related to cardiac monitoring as knowledge, skills, and competencies. Other organizational aspects were also reported as barriers. Addressing these learning needs through targeted CPD aligned with organizational initiatives can contribute to enhancing the quality of cardiac monitoring practices in ICUs.

Nurses' competency in electrocardiogram interpretation in acute care settings: A systematic review

AIMS

Identify and synthesize evidence of nurses' competency in electrocardiogram interpretation in acute care settings.

DESIGN

Systematic mixed studies review.

DATA SOURCES

Cumulative Index to Nursing and Allied Health Literature, Medline, Scopus and Cochrane were searched in April 2021.

REVIEW METHODS

Data were selected using the updated Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework. A data-based convergent synthesis design using qualitative content analysis was adopted. Quality appraisal was undertaken using validated tools appropriate to study designs of the included papers.

RESULTS

Forty-three papers were included in this review. Skills and attitudes were not commonly assessed, as most studies referred to 'competency' in the context of nurses' knowledge in electrocardiogram interpretation. Nurses' knowledge levels in this important nursing role varied notably, which could be partly due to a range of assessment tools being used. Several factors were found to influence nurses' competency in electrocardiogram interpretation across the included studies from individual, professional and organizational perspectives.

CONCLUSION

The definition of 'competency' was inconsistent, and nurses' competency in electrocardiogram interpretation varied from low to high. Nurses identified a lack of regular training and insufficient exposure in electrocardiogram interpretation. Hence, regular, standard training and education are recommended. Also, more research is needed to develop a standardized and comprehensive electrocardiogram interpretation tool, thereby allowing educators to safely assess nurses' competency.

IMPACT

This review addressed questions related to nurses' competency in electrocardiogram interpretation. The findings highlight varying competency levels and assessment methods. Nurses reported a lack of knowledge and confidence in interpreting electrocardiograms. There is an urgent need to explore opportunities to promote and maintain nurses' competency in electrocardiogram interpretation.

Capability of emergency nurses for electrocardiogram interpretation

INTRODUCTION

Electrocardiogram is the first-line diagnostic imaging modality for evaluating patients with chest pain. The present study aimed to determine the capability of emergency nurses for electrocardiogram interpretation by using a more appropriate questioning method.

METHODS

This was a cross-sectional descriptive survey. A convenience sample of 96 emergency nurses was obtained from two emergency departments in Hong Kong. The electrocardiogram-interpretation capability of the emergency nurses was determined using a self-developed well-designed questionnaire comprising 10 questions on electrocardiogram interpretation. Each question carried one point, such that the maximum score was 10 points. The higher the score, the more capable was the emergency nurse at electrocardiogram interpretation.

RESULTS

The mean score achieved by the participants was 7.7 ± 1.8. Only 12.5% of the participants were able to answer all questions correctly. A considerable proportion of the participants were unable to recognize first-degree heart block (74.0%), second-degree heart block type I (52.1%), or third-degree heart block (39.6%). Gender, electrocardiogram training, nursing experience, and emergency department experience had significant associations with mean score.

CONCLUSIONS

The electrocardiogram-interpretation capability of the emergency nurses was fair. Better training should be implemented to help emergency nurses recognize potentially fatal heart blocks, enabling prompt and appropriate patient treatment.

Among Unstable Angina and Non-ST-Elevation Myocardial Infarction Patients, Transient Myocardial Ischemia and Early Invasive Treatment Are Predictors of Major In-hospital Complications

BACKGROUND

Treatment for unstable angina (UA) or non-ST-elevation myocardial infarction (NSTEMI) is aimed at plaque stabilization to prevent infarction. Two treatment strategies are (1) invasive (ie, cardiac catheterization laboratory <24 hours after admission) or (2) selectively invasive (ie, medications with cardiac catheterization laboratory >24 hours for recurrent symptoms). However, it is not known if the frequency of transient myocardial ischemia (TMI) or complications during hospitalization varies by treatment.

PURPOSE

We aimed to (1) examine occurrence of TMI in UA/NSTEMI, (2) compare frequency of TMI by treatment pathway, and (3) determine predictors of in-hospital complications (ie, death, myocardial infarction [MI], pulmonary edema, shock, dysrhythmia with intervention).

METHODS

Hospitalized patients with coronary artery disease (ie, history of MI, percutaneous coronary intervention/stent, coronary artery bypass graft, >50% lesion via angiogram, or positive troponin) were recruited, and 12-lead electrocardiogram Holter initiated. Clinicians, blinded to Holter data, decided treatment strategy; offline analysis was done after discharge. Transient myocardial ischemia was defined as more than 1-mm ST segment ↑ or ↓, in more than 1 electrocardiographic lead, more than 1 minute.

RESULTS

Of 291 patients, 91% were white, 66% were male, 44% had prior MI, and 59% had prior percutaneous coronary intervention/stent or coronary artery bypass graft. Treatment pathway was early in 123 (42%) and selective in 168 (58%). Forty-nine (17%) had TMI: 19 (15%) early invasive, 30 (18%) selective (P = .637). Acute MI after admission was higher in patients with TMI regardless of treatment strategy (early: no TMI 4% vs yes TMI 21%; P = .020; selective: no TMI 1% vs yes TMI 13%; P = .0004). Predictors of major in-hospital complication were TMI (odds ratio, 9.9; 95% confidence interval, 3.84-25.78) and early invasive treatment (odds ratio 3.5; 95% confidence interval, 1.23-10.20).

CONCLUSIONS

In UA/NSTEMI patients treated with contemporary therapies, TMI is not uncommon. The presence of TMI and early invasive treatment are predictors of major in-hospital complications.
